THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE EXPIRATION OF THE APPLICABLE HOLDING PERIOD WITH RESPECT TO RESTRICTED SECURITIES SET FORTH IN RULE 144 UNDER THE SECURITIES ACT.

BY ITS ACQUISITION OF THIS SECURITY THE HOLDER AND ANY SUBSEQUENT TRANSFEREE HEREOF WILL BE DEEMED TO HAVE REPRESENTED AND WARRANTED THAT EITHER (I) THE PURCHASER IS NOT ACQUIRING OR HOLDING SUCH NOTE OR AN INTEREST THEREIN WITH THE ASSETS OF

(A) AN “EMPLOYEE BENEFIT PLAN” (AS DEFINED IN SECTION 3(3) OF ERISA) THAT IS SUBJECT TO ERISA, (B) A “PLAN” DESCRIBED IN SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”), (C) ANY ENTITY DEEMED TO HOLD “PLAN ASSETS” OF ANY OF THE FOREGOING BY REASON OF AN EMPLOYEE BENEFIT PLAN’S OR PLAN’S INVESTMENT IN SUCH ENTITY OR (D) A GOVERNMENTAL PLAN OR CHURCH PLAN SUBJECT TO SUCH PROVISIONS THAT ARE SIMILAR TO SUCH PROVISIONS OF ERISA OR THE CODE (COLLECTIVELY, “SIMILAR LAWS”) OR (II) THE ACQUISITION AND HOLDING OF SUCH NOTE BY THE PURCHASER, THROUGHOUT THE PERIOD THAT IT HOLDS SUCH NOTE AND THE DISPOSITION OF SUCH NOTE OR AN INTEREST THEREIN WILL NOT CONSTITUTE OR RESULT IN A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE, A BREACH OF FIDUCIARY DUTY UNDER ERISA OR A VIOLATION OF ANY PROVISIONS OF ANY APPLICABLE SIMILAR LAW.

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

(1) Each Global Note initially shall (x) be registered in the name of DTC or the nominee of DTC, (y) be delivered to the Notes Custodian for DTC and (z) bear legends as set forth in Section 2.1(d). Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the DTC, its successors or its respective nominees, except as set forth in Sections 2.1(e)(4) and 2.1(f). 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(f) 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(f), 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.

(f) 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 Exchange Act, 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(d). 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(e) 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. One Officer shall sign the Notes for each Issuer by manual, facsimile or PDF 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.

A Note shall not be valid until an authorized officer of the Trustee manually authenticates the Note. 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.

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 for original issue on the Issue Date in an aggregate principal amount of $1,325,000,000, (2) subject to the terms of this Indenture, Additional Notes for original issue in an unlimited principal amount, (3) Exchange Notes for issue only in an exchange offer pursuant to the Registration Rights Agreement and only in exchange for Initial Notes or Additional Notes of an equal principal amount and (4) 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, Additional Notes or Exchange Notes.

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 Trust Officer, 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.

In case either Issuer or any Guarantor, pursuant to Article IV or Section 10.2, as applicable, 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 Article IV, 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. The Issuers shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Notes may be presented for payment. The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Notes Register”) and, upon written request from either of the Issuers, the Registrar shall provide the Issuers with a copy of the Notes Register to enable them to maintain a register of the Notes at their registered offices. In accordance with the Luxembourg law of August 10, 1915 on commercial companies (as amended), the Company will maintain a register of Notes at its registered office. The Issuers may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any co-registrar.

The Issuers shall advise the Paying Agent in writing five Business Days prior to any interest payment date of any Additional Interest payable pursuant to the Registration Rights Agreement.

The Issuers shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. 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. If the Issuers fail to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.7. Either Issuer or any Guarantor may act as Paying Agent, Registrar or transfer agent.

The Issuers initially appoint the Trustee as Registrar and Paying Agent for the Notes. The Issuers may change any Registrar or Paying Agent without prior notice to the Holders, but upon 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. (Eastern 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 or any Guarantor 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. Upon any bankruptcy, reorganization or similar proceeding with respect to the Issuers, the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.5. Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, or to the extent otherwise required under the TIA, the Issuers, on their own behalf and on behalf of each of the Guarantors, shall furnish or cause the Registrar to furnish to the Trustee, in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders and the Issuers shall otherwise comply with TIA Section 312(a).

(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 Sections 2.1(e) and 2.1(f), 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. The Trustee shall refuse to register any requested transfer or exchange that does not comply with this Section 2.6.

(b) Transfers of Rule 144A Notes and Institutional Accredited Investor Notes. The following provisions shall apply with respect to any proposed registration of transfer of a Rule 144A Note or an Institutional Accredited Investor Note prior to the date that is one year after the later of the date of its original issue and the last date on which either Issuer or any Affiliate of the Issuers was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”):

(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

(2) a transfer of a Regulation S 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 the Issuers and the Registrar; and

(3) a transfer of a Regulation S Note or a beneficial interest therein to a Non-U.S. Person shall be made upon receipt by the Registrar or its agent of a certificate substantially in the form set forth in Section 2.9 hereof from the proposed transferee and receipt by the Registrar or its agent of an Opinion of Counsel, certification and/or other information satisfactory to the Issuers.

After the expiration of the Restricted Period, interests in the Regulation S Note may be transferred in accordance with applicable law without requiring the certification set forth in Section 2.8, Section 2.9 or Section 2.10 or any additional certification.

(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) Initial Notes are being exchanged for Exchange Notes in an exchange offer pursuant to the Registration Rights Agreement, in which case the Exchange Notes shall not bear a Restricted Notes Legend, (2) an Initial Note is being transferred pursuant to an effective registration statement, (3) Initial Notes are being exchanged for Notes that do not bear the Restricted Notes Legend in accordance with Section 2.6(e) or (4) 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 the 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 the Depositary 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 the Depositary, 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 Sections 2.2, 2.6, 2.11, 2.13, 3.5, 5.6 or 9.5).

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 forms of Notes attached hereto as Exhibits A, B and C) 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(f) 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(d).

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. The Trustee shall have no 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 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 may rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among 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.

This certificate is delivered to request a transfer of $[ ] principal amount of the 8.750% Senior Secured Notes due 2019 (the “Notes”) of Trinseo Materials Operating S.C.A. and Trinseo Materials Finance, Inc. (the “Issuers”).

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

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. 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 clause (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to the Issuers.

SECTION 2.10. Form of Certificate to Be Delivered in Connection with Transfers to AIs.

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

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(d) of the Indenture.

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 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 an indemnity bond sufficient in the judgment of the (i) Trustee to protect the Trustee and (ii) the Issuers to protect the Issuers, the Trustee, the Paying Agent and the Registrar, from any loss which any of them may suffer if a Note is replaced, 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 13.6 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 Trust 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.

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 13.2, 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.

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.

SECTION 3.1. Payment of Notes. The Issuers shall promptly pay the principal of, premium, if any, and interest (including Additional 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 (including Additional Interest) shall be considered paid on the date due if by 10:00 a.m. Eastern 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 (including Additional 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.

The Issuers shall pay interest on overdue principal at the rate specified therefor in the Notes, and it shall pay interest on overdue installments of interest (including Additional 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.

(7) Indebtedness permitted by this covenant need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this covenant permitting such Indebtedness; and

(8) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined on the basis of GAAP.

Accrual of interest, accrual of dividends, the accretion of accreted value, the accretion or amortization of original issue discount, the payment of interest in the form of additional Indebtedness, the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock or the reclassification of commitments or obligations not treated as Indebtedness due to a change in GAAP will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 3.2. The amount of any Indebtedness outstanding as of any date shall be (i) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (ii) the principal amount of the Indebtedness, or liquidation preference thereof, in the case of any other Indebtedness.

If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary of the Company as of such date (and, if such Indebtedness is not permitted to be Incurred as of such date under this Section 3.2, the Company shall be in default of this Section 3.2).

Notwithstanding any other provision of this Section 3.2, the maximum amount of Indebtedness that the Company or a Restricted Subsidiary may Incur pursuant to this Section 3.2 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

The Company and the Issuers shall not, and shall not permit any Guarantor to, directly or indirectly, Incur any Indebtedness (including Acquired Indebtedness and Permitted Debt) that is subordinated or junior in right of payment to any Indebtedness of the Company, the Issuers or such Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in right of payment to the Notes or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Company, the Issuers or such Guarantor, as the case may be; provided that for purposes of this Indenture, (1) unsecured Indebtedness shall not be treated as subordinated or junior to Secured Indebtedness merely because it is unsecured and (2) senior Indebtedness shall not be treated as subordinated or junior to any other senior Indebtedness merely because it has a junior priority with respect to the same collateral or is secured by different collateral.

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

(1) declare or pay any dividend or make any distribution on or in respect of the Company’s or any Restricted Subsidiary’s Capital Stock (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of their Restricted Subsidiaries), except:

(i) dividends or distributions payable in Capital Stock of the Company (other than Disqualified Stock) or in options, warrants or other rights to purchase such Capital Stock of the Company; and

(ii) dividends or distributions payable to the Company or a Restricted Subsidiary (and, in the case of any such Restricted Subsidiary making such dividend or distribution, to holders of its Capital Stock other than the Company or another Restricted Subsidiary on no more than a pro rata basis);

(2) purchase, repurchase, redeem, retire or otherwise acquire or retire for value any Capital Stock of the Company or any Parent of the Company held by Persons other than the Company or a Restricted Subsidiary of the Company;

(3) purchase, repurchase, redeem, defease or otherwise acquire or retire for value, prior to scheduled maturity, scheduled repayment or scheduled sinking fund payment, any Subordinated Indebtedness (other than (i) any such purchase, repurchase, redemption, defeasance or other acquisition or retirement in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case, due within one year of the date of purchase, repurchase, redemption, defeasance or other acquisition or retirement and (ii) any Indebtedness Incurred pursuant to Section 3.2(b)(4)); or

(any such dividend, distribution, purchase, redemption, repurchase, defeasance, other acquisition, retirement or Restricted Investment referred to in clauses (1) through (4) are referred to herein as a “Restricted Payment”), if at the time the Company or such Restricted Subsidiary makes such Restricted Payment:

(i) a Default shall have occurred and be continuing (or would result immediately thereafter therefrom);

(ii) the Company is not able to Incur an additional $1.00 of Indebtedness pursuant to Section 3.2(a) after giving effect, on a pro forma basis, to such Restricted Payment; or

(iii) the aggregate amount of such Restricted Payment and all other Restricted Payments made subsequent to the Issue Date (including Permitted Payments permitted by Sections 3.3(b)(6), (10), (11) and (17), but excluding all other Restricted Payments permitted by Section 3.3(b)) would exceed the sum of (without duplication):

(A) 50% of Consolidated Net Income for the period (treated as one accounting period) from January 1, 2013 to the end of the most recent fiscal quarter ending prior to the date of such Restricted Payment for which internal consolidated financial statements of the Company are available (or, in the case such Consolidated Net Income is a deficit, minus 100% of such deficit);

(B) 100% of the aggregate Net Cash Proceeds, and the fair market value of property or assets or marketable securities, received by the Company from the issue or sale of its Capital Stock (other than Disqualified Stock or Designated Preferred Stock) or as a result of a merger or consolidation (the consideration for which is Capital Stock of the Company) with another Person that is not a Restricted Subsidiary of the Company subsequent to the Issue Date or otherwise contributed to the equity (other than through the issuance of Disqualified Stock or Designated Preferred Stock) of the Company subsequent to the Issue Date (other than (x) Net Cash Proceeds or property or assets or marketable securities received from an issuance or sale of such Capital Stock to a Restricted Subsidiary or an employee stock ownership plan or trust established by the Company or any Subsidiary of the Company for the benefit of its employees to the extent funded by the Company or any Restricted Subsidiary, (y) Net Cash Proceeds or property or assets or marketable securities to the extent that any Restricted Payment has been made from such proceeds in reliance on Section 3.3(b)(6) and (z) Excluded Contributions);

(C) 100% of the aggregate Net Cash Proceeds, and the fair market value of property or assets or marketable securities, received by the Company or any Restricted Subsidiary from the issuance or sale (other than to the Company or a Restricted Subsidiary of the Company or an employee stock ownership plan or trust established by the Company or any Subsidiary of the Company for the benefit of their employees to the extent funded by the Company or any Restricted Subsidiary) by the Company or any Restricted

Subsidiary subsequent to the Issue Date of any Indebtedness, Disqualified Stock or Designated Preferred Stock that has been converted into or exchanged for Capital Stock of the Company (other than Disqualified Stock or Designated Preferred Stock) plus, without duplication, the amount of any cash, and the fair market value of property or assets or marketable securities, received by the Company or any Restricted Subsidiary upon such conversion or exchange;

(D) 100% of the aggregate amount received in cash and the fair market value, as determined in good faith by the Company, of marketable securities or other property received by means of: (a) the sale or other disposition (other than to the Company or a Restricted Subsidiary) of Restricted Investments made by the Company or its Restricted Subsidiaries and repurchases and redemptions of such Restricted Investments from the Company or its Restricted Subsidiaries and repayments of loans or advances, and releases of guarantees, which constitute Restricted Investments by the Company or its Restricted Subsidiaries, in each case after the Issue Date or (ii) the sale (other than to the Company or a Restricted Subsidiary) of the stock of an Unrestricted Subsidiary or a distribution from an Unrestricted Subsidiary (other than in each case to the extent of the amount of the Investment in such Unrestricted Subsidiary made by the Company or a Restricted Subsidiary pursuant Section 3.3(b)(10) or (14) or to the extent of the amount of the Investment that constituted a Permitted Investment) or a dividend from an Unrestricted Subsidiary after the Issue Date; and

(E) in the case of the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary or the merger or consolidation of an Unrestricted Subsidiary into the Company or a Restricted Subsidiary or the transfer of all or substantially all of the assets of an Unrestricted Subsidiary to the Company or a Restricted Subsidiary after the Issue Date, the fair market value of the Investment in such Unrestricted Subsidiary (or the assets transferred), as determined in good faith by the Company at the time of the redesignation of such Unrestricted Subsidiary as a Restricted Subsidiary or at the time of such merger or consolidation or transfer of assets (after taking into consideration any Indebtedness associated with the Unrestricted Subsidiary so designated or merged or consolidated or Indebtedness associated with the assets so transferred), other than to the extent of the amount of the Investment in such Unrestricted Subsidiary made by the Company or a Restricted Subsidiary pursuant to Section 3.3(b)(10) or (14) or to the extent of the amount of the Investment that constituted a Permitted Investment.

(b) Section 3.3(a) will not prohibit any of the following (collectively, “Permitted Payments”):

(1) the payment of any dividend or distribution within 60 days after the date of declaration thereof, if at the date of declaration such payment would have complied with the provisions of this Indenture or the redemption, repurchase or retirement of Indebtedness if, at the date of any irrevocable redemption notice, such payment would have complied with the provisions of this Indenture;

(2) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Capital Stock or Subordinated Indebtedness made by exchange (including any such exchange pursuant to the exercise of a conversion right or privilege in connection with which cash is paid in lieu of the issuance of fractional shares) for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of the Company (other than Disqualified Stock or Designated Preferred Stock) (“Refunding Capital Stock”) or a substantially concurrent contribution to the equity (other than through the issuance of Disqualified Stock or Designated Preferred Stock or through an Excluded Contribution) of the Company; provided, however, that to the extent so applied, the Net Cash Proceeds, or fair market value of property or assets or of marketable securities, from such sale of Capital Stock or such contribution will be excluded from Section 3.3(a)(iii);

(3) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Subordinated Indebtedness made by exchange for, or out of the proceeds of the substantially concurrent sale of, Refinancing Indebtedness permitted to be Incurred pursuant to Section 3.2;

(4) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Preferred Stock of the Company or a Restricted Subsidiary made by exchange for or out of the proceeds of the substantially concurrent sale of Preferred Stock of the Company or a Restricted Subsidiary, as the case may be, that, in each case, is permitted to be Incurred pursuant to Section 3.2;

(5) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Subordinated Indebtedness or Disqualified Stock or Preferred Stock of a Restricted Subsidiary:

(ii) to the extent required by the agreement governing such Subordinated Indebtedness, Disqualified Stock or Preferred Stock, following the occurrence of a Change of Control (or other similar event described therein as a “change of control”), but only if the Company shall have first complied with Section 3.9 and purchased all Notes tendered pursuant to the offer to repurchase all the Notes required thereby, prior to purchasing, repurchasing, redeeming, defeasing or otherwise acquiring or retiring such Subordinated Indebtedness, Disqualified Stock or Preferred Stock; or

(iii) consisting of Acquired Indebtedness (other than Indebtedness Incurred (A) to provide all or any portion of the funds utilized to consummate the transaction or series of related transactions pursuant to which such Person became a Restricted Subsidiary or was otherwise acquired by the Company or a Restricted Subsidiary or (B) otherwise in connection with or contemplation of such acquisition);

(6) a Restricted Payment to pay for the repurchase, retirement or other acquisition or retirement for value of Capital Stock (other than Disqualified Stock) of the Company or any of its Parents held by any future, present or former employee, director or consultant of the Company, any of its Subsidiaries or any of their Parents (or permitted transferees, assigns, estates, trusts or heirs of such employee, director or consultant) either pursuant to any management equity plan or stock option plan or any other management or employee benefit plan or agreement or upon the termination of such employee, director or consultant’s employment or directorship; provided, however, that the aggregate Restricted Payments made under this clause (6) do not exceed (i) prior to the consummation of an underwritten public Equity Offering of the common stock or common equity interests of the Company or any Parent, $15.0 million in any calendar year and (ii) following the consummation of an underwritten public Equity Offering of the common stock or common equity interests of the Company or any Parent, $30.0 million (in each case, with unused amounts in any calendar year being carried over for the two immediately succeeding calendar years); provided further that such amount in any calendar year may be increased by an amount not to exceed:

(i) the cash proceeds from the sale of Capital Stock (other than Disqualified Stock or Designated Preferred Stock) of the Company and, to the extent contributed to the capital of the Company (other than through the issuance of Disqualified Stock or Designated Preferred Stock or an Excluded Contribution), Capital Stock of any of the Company’s Parents, in each case to members of management, directors or consultants of the Company, any of its Subsidiaries or any of its Parents that occurred after the Issue Date, to the extent the cash proceeds from the sale of such Capital Stock have not otherwise been applied to the payment of Restricted Payments by virtue of Section 3.3(a)(iii); plus

(ii) the cash proceeds of key man life insurance policies received by the Company and its Restricted Subsidiaries after the Issue Date; less

(iii) the amount of any Restricted Payments made in previous calendar years pursuant to clauses (i) and (ii) of this Section 3.3(b)(6);

and provided further that cancellation of Indebtedness owing to the Company or any Restricted Subsidiary from members of management, directors, employees or consultants of the Company, any of the Company’s Parents or any of its Restricted Subsidiaries in connection with a repurchase of Capital Stock of the Company or any of its Parents will not be deemed to constitute a Restricted Payment for purposes of this covenant or any other provision of this Indenture;

(7) the declaration and payment of dividends on Disqualified Stock, or Preferred Stock of a Restricted Subsidiary, Incurred in accordance with Section 3.2;

(8) purchases, repurchases, redemptions, defeasances or other acquisitions or retirements of Capital Stock deemed to occur upon the exercise of stock options, warrants or other rights in respect thereof if such Capital Stock represents a portion of the exercise price thereof;

(11) payments by the Company, or loans, advances, dividends or distributions to any Parent to make payments, to holders of Capital Stock of the Company or any Parent in lieu of the issuance of fractional shares of such Capital Stock; provided, however, that any such payment, loan, advance, dividend or distribution shall not be for the purpose of evading any limitation of this covenant or otherwise to facilitate any dividend or other return of capital to the holders of such Capital Stock (as determined in good faith by the Board of Directors);

(13) (i) the declaration and payment of dividends on Designated Preferred Stock of the Company issued after the Issue Date; and (ii) the declaration and payment of dividends on Refunding Capital Stock that is Preferred Stock; provided, however, that, in the case of clause (i), the amount of all dividends declared or paid pursuant to this clause shall not exceed the Net Cash Proceeds received by the Company or the aggregate amount contributed in cash to the equity (other than through the issuance of Disqualified Stock or an Excluded Contribution of the Company), from the issuance or sale of such Designated Preferred Stock; provided further, in the case of clause (ii), that for the most recently ended four fiscal quarters for which internal financial statements are available immediately preceding the date of issuance of such Designated Preferred Stock, after giving effect to such issuance on a pro forma basis the Company would be permitted to Incur at least $1.00 of additional Indebtedness pursuant to Section 3.2(a);

(17) so long as no Default or Event of Default has occurred and is continuing (or would result therefrom), Restricted Payments (including loans or advances) in an aggregate amount outstanding at the time made not to exceed $75.0 million; and

(18) so long as no Default or Event of Default has occurred and is continuing (or would result therefrom), mandatory redemptions of Disqualified Stock issued as a Restricted Payment permitted to be made under this covenant, or as a Permitted Payment (excluding this clause (18)) or as consideration for a Permitted Investment; provided that the aggregate amount of such Disqualified Stock redeemed will not, in each case, exceed the amount of such initial Restricted Payment, Permitted Payment or Permitted Investment.

For purposes of determining compliance with this Section 3.3, in the event that a Restricted Payment meets the criteria of more than one of the categories of Permitted Payments described in clauses (1) through (18) above, or is permitted pursuant to Section 3.3(a), the Company will be entitled to classify such Restricted Payment (or portion thereof) on the date of its payment or later reclassify such Restricted Payment (or portion thereof) in any manner that complies with this Section 3.3.

The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of such Restricted Payment of the asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment. The fair market value of any cash Restricted Payment shall be its face amount, and the fair market value of any non-cash Restricted Payment, property or assets other than cash shall be determined conclusively by the Board of Directors of the Company acting in good faith.

Notwithstanding the foregoing provisions of this Section 3.3, the Company will not, and will not permit any of its Restricted Subsidiaries to, declare or pay any cash dividend or make any cash distribution on or in respect of the Company’s Capital Stock or purchase for cash or otherwise acquire for cash any Capital Stock of the Company or any other direct or indirect parent of the Company, for the purpose of paying any cash dividend or making any cash distribution to, or acquiring Capital Stock of any direct or indirect parent of the Company for cash from, the Permitted Holders, in each case by means of utilization of the cumulative Restricted Payment credit provided by the first paragraph of this covenant, unless at the time and after giving effect to such payment, the Consolidated Secured Leverage Ratio of the Company and its Restricted Subsidiaries would be less than 3.50 to 1.00.

SECTION 3.4. Limitation on Restrictions on Distributions from Restricted Subsidiaries.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any of its Restricted Subsidiaries to:

(1) pay dividends or make any other distributions in cash or otherwise on its Capital Stock or pay any Indebtedness or other obligations owed to the Company or any of its Restricted Subsidiaries;

(3) sell, lease or transfer any of its property or assets to the Company or any Restricted Subsidiary;

provided that (x) the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock or other common equity interests and (y) the subordination

of (including the application of any standstill requirements to) loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness Incurred by the Company or any Restricted Subsidiary shall not be deemed to constitute such an encumbrance or restriction.

(1) any encumbrance or restriction pursuant to (i) any Credit Facility or (ii) any other agreement or instrument, in each case, in effect at or entered into on the Issue Date;

(2) any encumbrance or restriction pursuant to this Indenture, the Notes, the Note Guarantees and the Security Documents;

(5) any encumbrance or restriction (i) that restricts in a customary manner the subletting, assignment or transfer of any property or asset that is subject to a lease, license or similar contract or agreement, or the assignment or transfer of any lease, license or other contract or agreement; (ii) contained in mortgages, pledges, charges or other security agreements permitted under this Indenture or securing Indebtedness of the Company or a Restricted Subsidiary permitted under this Indenture to the extent such encumbrances or restrictions restrict the transfer or encumbrance of the property or assets subject to such mortgages, pledges, charges or other security agreements; or (iii) pursuant to customary provisions restricting dispositions of real property interests set forth in any reciprocal easement agreements of the Company or any Restricted Subsidiary;

(6) any encumbrance or restriction pursuant to Purchase Money Obligations and Capitalized Lease Obligations permitted under this Indenture, in each case, that impose encumbrances or restrictions on the property so acquired;

(7) any encumbrance or restriction imposed pursuant to an agreement entered into for the direct or indirect sale or disposition to a Person of all or substantially all the Capital Stock or assets of the Company or any Restricted Subsidiary (or the property or assets that are subject to such restriction) pending the closing of such sale or disposition;

(12) other Indebtedness, Disqualified Stock or Preferred Stock of Foreign Subsidiaries permitted to be Incurred or issued subsequent to the Issue Date pursuant Section 3.2 that impose restrictions solely on the Foreign Subsidiaries party thereto or their Subsidiaries;

(13) restrictions created in connection with any Qualified Securitization Financing that, in the good faith determination of the Company are necessary or advisable to effect such Securitization Facility;

(14) any encumbrance or restriction arising pursuant to an agreement or instrument relating to any Indebtedness permitted to be Incurred subsequent to the Issue Date pursuant to Section 3.2 if (A) the Company determines at the time of issuance of such Indebtedness that such encumbrances or restrictions will not adversely affect, in any material respect, the Issuers’ ability to make principal or interest payments on the Notes or (B) such encumbrance or restriction applies only during the continuance of a default relating to such Indebtedness;

(15) any encumbrance or restriction existing by reason of any Lien permitted under Section 3.6; or

(16) any encumbrance or restriction pursuant to an agreement or instrument effecting a refinancing of Indebtedness Incurred pursuant to, or that otherwise refinances, an agreement or instrument referred to in clauses (1) to (15) of this Section 3.4(b) or this clause (16) (an “Initial Agreement”) or contained in any amendment, supplement or other modification to an agreement referred to in clauses (1) to (15) of this Section 3.4(b) or this clause (16); provided, however, that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such agreement or instrument are no less favorable in any material respect to the Holders taken as a whole than the encumbrances and restrictions contained in the Initial Agreement or Initial Agreements to which such refinancing or amendment, supplement or other modification relates (as determined in good faith by the Company).

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless:

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration (including by way of relief from, or by any other Person assuming responsibility for, any liabilities, contingent or otherwise) at least equal to the fair market value (such fair market value to be determined on the date of contractually agreeing to such Asset Disposition), as determined in good faith by the Board of Directors of the Company, of the shares and assets subject to such Asset Disposition (including, for the avoidance of doubt, if such Asset Disposition is a Permitted Asset Swap);

(2) in any such Asset Disposition, or series of related Asset Dispositions (except to the extent the Asset Disposition is a Permitted Asset Swap), at least 75% of the consideration from such Asset Disposition (including by way of relief from, or by any other Person assuming responsibility for, any liabilities, contingent or otherwise) received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; and

(3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company or any Restricted Subsidiary, as the case may be:

(i) to the extent such Net Available Cash constitutes proceeds from Collateral, (A) to prepay, repay or purchase any Payment Priority Obligation (in each case, other than Indebtedness owed to the Company or any Restricted Subsidiary); provided, however, that, in connection with any prepayment, repayment or purchase of Indebtedness pursuant to this clause (i), the Company or such Restricted Subsidiary will retire such Indebtedness and will cause the related commitment

(if any) to be reduced in an amount equal to the principal amount so prepaid, repaid or purchased; or (B) to prepay, repay or purchase Pari Passu Secured Obligations at a price of no more than 100% of the principal amount of such Pari Passu Secured Obligations plus accrued and unpaid interest to the date of such prepayment, repayment or purchase; provided that, to the extent the Company redeems, repays or repurchases Pari Passu Secured Obligations pursuant to this clause (B), the Issuers shall equally and ratably reduce Obligations under the Notes as provided under Section 5.7, through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for an Asset Disposition Offer) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be prepaid;

(ii) if the assets subject to such Asset Disposition are the property or assets of a Restricted Subsidiary that is not a Guarantor, to permanently reduce Indebtedness of (i) a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to an Issuer or any Restricted Subsidiary, or (ii) an Issuer or a Guarantor;

(iii) to the extent the Company or such Restricted Subsidiary elects to invest in or commit to invest in Additional Assets (including by means of an investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by the Company or another Restricted Subsidiary) within 365 days from the later of (A) the date of such Asset Disposition and (B) the receipt of such Net Available Cash; provided, that a binding commitment to make an investment of Additional Assets shall be treated as a permitted application of the Net Available Cash from the date of such commitment; provided further that (x) in the event such binding commitment is later canceled or terminated for any reason before such Net Available Cash is so applied, the Company or such Restricted Subsidiary may satisfy its obligation as to any Net Available Cash by entering into another binding commitment within 180 days of such cancellation or termination of the prior binding commitment and (y) if such investment is not consummated within the period set forth in clause (x) or such binding commitment is terminated, the Net Available Cash not so applied will be deemed to be Excess Proceeds (as defined below); provided further (i) that the Company or such Restricted Subsidiary may only enter into such a commitment under clause (x) one time with respect to each Asset Disposition and (ii) the assets (including Capital Stock) acquired with the Net Available Cash of an Asset Disposition of Collateral are pledged as Collateral; or

(iv) to the extent such Net Available Cash from such Asset Disposition does not constitute proceeds from Collateral, any of clauses (i), (ii) and (iii) of Section 3.5(a)(3);

provided that, pending the final application of any such Net Available Cash in accordance with clause (i) or clause (ii) above, the Company and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise use such Net Available Cash in any manner not prohibited by this Indenture.

(b) Any Net Available Cash from Asset Dispositions that is not applied or invested or committed to be applied or invested as provided in Section 3.5(a) will be deemed to constitute “Excess Proceeds” under this Indenture. On the 366th day after an Asset Disposition, if the aggregate amount of Excess Proceeds under this Indenture exceeds $50.0 million, the Company will within 10 Business Days be required to make an offer (“Asset Disposition Offer”) to all Holders of Notes issued under this Indenture and, to the extent the Company elects, to all holders of other outstanding Pari Passu Secured Obligations, to purchase the maximum principal amount of Notes and any such Pari Passu Secured Obligations to which the Asset Disposition Offer applies that may be purchased out of the Excess Proceeds, at an offer price in respect of the Notes in an amount equal to 100% of the principal amount of the Notes and Pari Passu Secured Obligations, in each case, plus accrued and unpaid interest, if any, to, but not including, the date of purchase, in accordance with the procedures set forth in this Indenture or the agreements governing the Pari Passu Indebtedness, as applicable, and, with respect to the Notes, in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof. The Issuers will deliver notice of such Asset Disposition Offer electronically or by first-class mail, with a copy to the Trustee, to each Holder of Notes at the address of such Holder appearing in the security register or otherwise in accordance with the procedures of DTC, describing the transaction or transactions that constitute the Asset Disposition and offering to repurchase the Notes for the specified purchase price on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is delivered, pursuant to the procedures required by this Indenture and described in such notice.

(c) To the extent that the aggregate amount of Notes and Pari Passu Secured Obligations so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for any purpose not prohibited by this Indenture. If the aggregate principal amount of the Notes surrendered in any Asset Disposition Offer by Holders and other Pari Passu Secured Obligations surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Excess Proceeds shall be allocated by the Company among the Notes and Pari Passu Secured Obligations to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Notes and Pari Passu Secured Obligations, subject to adjustments so that no Note in an unauthorized amount remains outstanding. Upon completion of any Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

(d) To the extent that any portion of Net Available Cash payable in respect of the Notes is denominated in a currency other than U.S. dollars, the amount thereof payable in respect of the Notes shall not exceed the net amount of funds in U.S. dollars that is actually received by the Company upon converting such portion into U.S. dollars.

(e) For the purposes of Section 3.5(a)(2) hereof, the following will be deemed to be cash:

(1) the assumption by the transferee of Indebtedness or other liabilities contingent or otherwise of the Company or a Restricted Subsidiary (other than Subordinated Indebtedness, Disqualified Stock of the Company or a Guarantor or Preferred Stock of a Guarantor) and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness or other liability in connection with such Asset Disposition;

(2) securities, notes or other obligations received by the Company or any Restricted Subsidiary of the Company from the transferee that are converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents within 180 days following the closing of such Asset Disposition;

(3) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Disposition, to the extent that the Company and each other Restricted Subsidiary are released from any Guarantee of payment of such Indebtedness in connection with such Asset Disposition;

(4) consideration consisting of Indebtedness of the Company (other than Subordinated Indebtedness or Disqualified Stock) received after the Issue Date from Persons who are not the Company or any Restricted Subsidiary; and

(5) any Designated Non-Cash Consideration received by Holdings, the Company or any Restricted Subsidiary in such Asset Dispositions having an aggregate fair market value, taken together with all other Designated Non-Cash Consideration received pursuant to this covenant that is at that time outstanding, not to exceed the greater of (i) $100.0 million and (ii) 3.5% of Total Assets (with the fair market value of each item of Designated Non-Cash Consideration being measured at the time received and without giving effect to subsequent changes in value).

(f) The Issuers will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to this Section 3.5.

SECTION 3.6. Limitation on Liens. The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, Incur or permit to exist any Lien (other than Permitted Liens) upon any of their property or assets (including Capital Stock of a Restricted Subsidiary of the Company), whether owned on the Issue Date or acquired after that date, which Lien secures any Indebtedness.

Any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the Incurrence of such Indebtedness shall also be permitted to secure any Increased Amount with respect to such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness as a result of any accrual of interest, any accretion of accreted value or liquidation preference, any amortization of original issue discount, any fluctuations in the exchange rate of currencies, the payment of interest in the form of additional Indebtedness with the same terms or the payment of dividends on Preferred Stock in the form of additional shares of Preferred Stock of the same class.

(a) The Company shall not permit any of its Wholly Owned Subsidiaries that are Restricted Subsidiaries (and non-Wholly Owned Subsidiaries if such non-Wholly Owned Subsidiaries guarantee other capital markets debt securities of the Company or any Restricted Subsidiary or guarantee all or a portion of the Credit Agreement), other than a Guarantor, to Guarantee the payment of any Indebtedness of the Company or any other Guarantor unless:

(1) such Restricted Subsidiary within 30 days executes and delivers a supplemental indenture to this Indenture and joinder or supplement to the Registration Rights Agreement providing for a senior Guarantee by such Restricted Subsidiary, and (i) executes and delivers a supplement or joinder to the Security Documents, or executes and delivers new Security Documents, and any Intercreditor Agreement and takes all actions required thereunder to perfect the Liens created thereunder; provided that

(i) if such Indebtedness is by its express terms subordinated in right of payment to the Notes or such Guarantor’s Guarantee, any such Guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee with respect to the Notes substantially to the same extent as such Indebtedness is subordinated to the Notes or such Guarantor’s Guarantee of the Notes; and

(ii) if the Notes or such Guarantor’s Guarantee is subordinated in right of payment to such Indebtedness, the Guarantee under the supplemental indenture shall be subordinated to such Restricted Subsidiary’s guarantee with respect to such Indebtedness substantially to the same extent as the Notes or the Guarantor’s Guarantee is subordinated to such Indebtedness; and

(2) such Restricted Subsidiary providing a Note Guarantee in accordance with this covenant will (i) waive and will not in any manner whatsoever claim or take the benefit or advantage of, any rights of reimbursement, indemnity or subrogation or any other rights against the Company or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary under its Guarantee until payment in full of Obligations under this Indenture; and (ii) deliver to the Trustee an Opinion of Counsel to the effect that:

(ii) such Guarantee constitutes a valid, binding and enforceable obligation of such Restricted Subsidiary, except insofar as enforcement thereof may be limited by bankruptcy, insolvency or similar laws (including, without limitation, all laws relating to fraudulent transfers) and except insofar as enforcement thereof is subject to general principals of equity;

provided that this Section 3.7 shall not be applicable (i) to any guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary, or (ii) in the event that the Guarantee of the Company’s obligations under the Notes or this Indenture by such Subsidiary would not be permitted by applicable law, rule or regulation.

In addition, upon the Guarantee by any Post-Closing Guarantor that was previously prohibited under applicable law, rule or regulation from Guaranteeing the Company’s obligations under the Notes and this Indenture becoming permissible under all such laws, rules and regulations, such Post-Closing Guarantor will promptly execute and deliver a supplemental indenture to this Indenture and joinder or supplement to the Registration Rights Agreement providing for a senior Guarantee by such Post-Closing Guarantor and supplement or joinder to the Security Documents.

(b) The Company may elect, in its sole discretion, to cause any Subsidiary that is not otherwise required to be a Guarantor to become a Guarantor, in which case such Subsidiary shall only be required to comply with the 30-day period described in Section 3.7(a).

(c) If any Guarantor becomes an Immaterial Subsidiary, the Company 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 described in the first paragraph above 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).

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or conduct any transaction (including the purchase, sale, lease or exchange of any property or the rendering of any service) with any Affiliate of the Company (an “Affiliate Transaction”) involving aggregate value in excess of $5.0 million unless:

(1) the terms of such Affiliate Transaction taken as a whole are not materially less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable transaction at the time of such transaction or the execution of the agreement providing for such transaction in arm’s length dealings with a Person who is not such an Affiliate; and

(2) in the event such Affiliate Transaction involves an aggregate value in excess of $10.0 million, the terms of such transaction have been approved by a majority of the members of the Board of Directors.

Any Affiliate Transaction shall be deemed to have satisfied the requirements set forth in clause (2) of this Section 3.8(a) if such Affiliate Transaction is approved by a majority of the Disinterested Directors, if any.

(1) any Restricted Payment permitted to be made pursuant to Section 3.3, or any Permitted Investment;

(2) any issuance or sale of Capital Stock, options, other equity-related interests or other securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, or entering into, or maintenance of, any employment, consulting, collective bargaining or benefit plan, program, agreement or arrangement, related trust or other similar agreement and other compensation arrangements, options, warrants or other rights to purchase Capital Stock of the Company, any Restricted Subsidiary or any Parent, restricted stock plans, long-term incentive plans, stock appreciation rights plans, participation plans or similar employee benefits or consultants’ plans (including valuation, health, insurance, deferred compensation, severance, retirement, savings or similar plans, programs or arrangements) or indemnities provided on behalf of officers, employees, directors or consultants approved by the Board of Directors of the Company, in each case in the ordinary course of business;

(6) the entry into and performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of any transaction arising out of, and any payments pursuant to or for purposes of funding, any agreement or instrument in effect as of or on the Issue Date, as these agreements and instruments may be amended, modified, supplemented, extended, renewed or refinanced from time to time in accordance with the other terms of this covenant or to the extent not more disadvantageous to the Holders in any material respect;

(7) any customary transaction with a Securitization Entity effected as part of a Qualified Securitization Financing;

(8) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of business, which are fair to the Company or the relevant Restricted Subsidiary in the reasonable determination of the Board of Directors or the senior management of the Company or the relevant Restricted Subsidiary, or are on terms no less favorable than those that could reasonably have been obtained at such time from an unaffiliated party;

(9) any transaction between or among the Company or any Restricted Subsidiary and any Affiliate of the Company or an Associate or similar entity that would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary or any Affiliate of the Company or a Restricted Subsidiary or any Affiliate of any Permitted Holder owns an equity interest in or otherwise controls such Affiliate, Associate or similar entity;

(10) issuances or sales of Capital Stock (other than Disqualified Stock or Designated Preferred Stock) of the Company or options, warrants or other rights to acquire such Capital Stock and the granting of registration and other customary rights in connection therewith or any contribution to capital of the Company or any Restricted Subsidiary;

(16) any purchases by the Company’s Affiliates of Indebtedness or Disqualified Stock of the Company or any of its Restricted Subsidiaries the majority of which Indebtedness or Disqualified Stock is purchased by Persons who are not the Company’s Affiliates; provided that such purchases by the Company’s Affiliates are on the same terms as such purchases by such Persons who are not the Company’s Affiliates.

(a) If a Change of Control occurs, unless the Issuers have previously or concurrently mailed a redemption notice with respect to all of the outstanding Notes as set forth under Section 5.7(a) or Section 5.7(b), the Issuers shall make an offer to purchase all of the Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to but excluding the date of repurchase, subject to the right of Holders of the Notes of record on the relevant record date to receive interest due on the relevant interest payment date. Within 30 days following any Change of Control, the Company will send notice of such Change of Control Offer electronically or by first class mail, with a copy to the Trustee, to each Holder of Notes at the address of such Holder appearing in the security register or otherwise in accordance with the procedures of DTC, with the following information:

(6) that Holders will be entitled to withdraw their tendered Notes and their election to require the Issuers to purchase such Notes; provided that the Paying Agent receives, not later than the close of

business on the second Business Day prior to the expiration date of the Change of Control Offer, a telegram, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

The unpurchased portion of the Notes must be equal to at least $2,000 or any integral multiple of $1,000 in excess of $2,000;

(8) if such notice is delivered prior to the occurrence of a Change of Control, stating that the Change of Control Offer is conditional on the occurrence of such Change of Control; and

(3) deliver, or cause to be delivered, to the Trustee for cancellation the Notes so accepted together with an Officer’s Certificate to the Trustee stating that such Notes or portions thereof have been tendered to and purchased by the Issuers.

(c) The Issuers will not be required to make a Change of Control Offer following a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuers and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer, or (2) notice of redemption of all outstanding Notes has been given pursuant to this Indenture as described in Section 5.7, unless and until there is a default in the payment of the redemption price on the applicable Redemption Date or the redemption is not consummated due to the failure of a condition precedent contained in the applicable redemption notice to be satisfied.

(d) Notwithstanding anything to the contrary in this Section 3.9, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer.

(e) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Issuers, or any third party making a Change of Control Offer in lieu of the Issuers as described in this Section 3.9, purchases all of the Notes validly tendered

and not withdrawn by such Holders, the Issuers or such third party will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer, to redeem all Notes that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest to but excluding the date of redemption.

(f) The Issuers will comply with the requirements of Section 14(e) under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuers will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

(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), the Company will furnish to the Trustee, within 15 days after the time periods specified below:

(1) all financial information 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 the Company is a “foreign private issuer” as such term is defined under the rules and regulations of the SEC), if the Company 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 the Company’s certified independent accountants but within 120 days after the end of each fiscal year and within 60 days after the end of each fiscal quarter; 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 the Company is a “foreign private issuer” as such term is defined under the rules and regulations of the SEC) if the Company 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. Notwithstanding the foregoing, the Company shall not be so obligated to file such reports with the SEC (i) if the SEC does not permit such filing or (ii) prior to the consummation of an exchange offer or the effectiveness of a shelf registration statement as required by the Registration Rights Agreement, so long as, if clause (i) or (ii) is applicable, the Company makes available such information to prospective purchasers of Notes, in addition to providing such information to the Trustee and the Holders of the Notes, in each case, at the Company’s expense and by the applicable date the Company would be required to file such information pursuant to the immediately preceding sentence. 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; provided that such cure shall not otherwise affect the rights of the Holders under Section 6.1 if Holders of at least 30% in principal amount of the then total outstanding Notes have declared the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately and such declaration shall not have been rescinded or cancelled prior to such cure. In addition, to the extent not satisfied by the foregoing, the Company will agree that, for so long as any Notes are outstanding, it will furnish to Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(b) Substantially concurrently with the furnishing or making such information available to the Trustee pursuant to Section 3.10(a), the Company shall also post copies of such information required by Section 3.10(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 investors in the Notes (which prospective investors 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.

(c) 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 Company’s equity investors and analysts). The conference call will be following the last day of each fiscal quarter of the Company and not later than 10 Business Days from the time that the Company distributes the financial information as set forth in Section 3.10(b). No fewer than two days prior to the conference call, 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.

(d) For so long as any direct or indirect parent company of the Company is a guarantor of the Notes, the Company may satisfy its obligations pursuant to this Section 3.10 with respect to financial information relating to the Company by furnishing financial information relating to such parent; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such parent, on the one hand, and the information relating to the Company and its Restricted Subsidiaries on a standalone basis, on the other hand.

(a) If on or after the Issue Date (1) a Wholly Owned Subsidiary (other than an Immaterial Subsidiary) that is not a Guarantor Guarantees the Credit Agreement, or (2) the Company or any of its Restricted Subsidiaries acquires or creates a Wholly Owned Subsidiary (other than an Immaterial Subsidiary) and such Wholly Owned Subsidiary Guarantees the Credit Agreement, then, in each case, the Company shall cause such Wholly Owned Subsidiary to become a Guarantor and execute and deliver (within five Business Days of guaranteeing the Credit Agreement or becoming a Wholly Owned Subsidiary, as the case may be) to the Trustee a supplemental indenture substantially in the form of Exhibit C hereto, pursuant to which such Wholly Owned Subsidiary shall unconditionally Guarantee, on a joint and several basis with the other Guarantors, the full and prompt payment of the principal of, premium, if any, interest and Additional Interest, if any, in respect of the Notes on a senior basis and all other obligations under this Indenture.

(b) The Company shall not permit any Wholly Owned Subsidiary (other than an Immaterial Subsidiary), directly or indirectly, to Guarantee the Credit Agreement unless such Wholly Owned Subsidiary (i) is a Guarantor or (ii) within five Business Days executes and delivers (x) to the Trustee a supplemental indenture substantially in the form of Exhibit C hereto, pursuant to which such Wholly Owned Subsidiary shall unconditionally Guarantee, on a joint and several basis with the other Guarantors, the full and prompt payment of the principal of, premium, if any, interest and Additional Interest, if any, in respect of the Notes on a senior basis and all other obligations under this Indenture and (y) a supplement or joinder agreement to the applicable Security Documents or new Security Documents, as applicable, providing for a pledge of its assets as Collateral for the Notes to the same extent as set forth in such Security Documents and take all actions required under such Security Documents to perfect the Liens created under such Security Documents.

SECTION 3.12. 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, which initially shall be located at Wilmington Trust, National Association, Corporate Capital Markets, 50 South Sixth Street, Suite 1290, Minneapolis, MN 55402-1544, Attention: Trinseo Materials Administrator, 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 3.13. 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 corporate 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 3.14. Payment of Taxes. The Company 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 the Company or any Subsidiary; provided, however, that the Company 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 Company), are being maintained in accordance with GAAP or where the failure to effect such payment will not be disadvantageous to the Holders.

SECTION 3.15. 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 Registration Rights Agreement, the Notes or the 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 3.16. 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. The Issuers also shall comply with TIA Section 314(a)(4) and 314(b).

SECTION 3.17. Further Instruments and Acts. Upon request of the Trustee or as necessary to comply with future developments or requirements, the Issuers will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 3.18. Conduct of Business. The Issuers will not, and will not permit any of their Restricted Subsidiaries to, engage in any businesses other than any business conducted or proposed to be conducted by the Issuers and their Restricted Subsidiaries on the Issue Date or any business that is similar, reasonably related, incidental or ancillary thereto or any reasonable extension thereof.

SECTION 3.19. 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 3.20. Designation of Restricted and Unrestricted Subsidiaries. The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not

cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 3.3 or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default.

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Company giving effect to such designation and an Officer’s Certificate of the Company certifying that such designation complies with the preceding conditions and was permitted by the covenant described above under Section 3.3. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under the covenant described under Section 3.2, the Company will be in default of such covenant.

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an Incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under the covenant described under Section 3.2, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be in existence following such designation.

Any such designation by the Board of Directors of the Company shall be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors of the Company giving effect to such designation and an Officer’s Certificate of the Company certifying that such designation complies with the preceding conditions.

SECTION 3.21. Suspension of Certain Covenants. Following the first day the Notes have achieved Investment Grade Status and no Default or Event of Default has occurred and is continuing under this Indenture, then beginning on that day and ending on a Reversion Date (such period a “Suspension Period”), the Issuers and the Company’s Restricted Subsidiaries will not be subject to Sections 3.2, 3.3, 3.4, 3.5, 3.7, 3.8 and 4.1(a)(3).

On each Reversion Date, all Indebtedness Incurred during the Suspension Period will be classified as having been Incurred pursuant to Section 3.2(a) or one of the clauses of Section 3.2(b) (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to the Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be Incurred pursuant to Section 3.2(a) or (b), such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 3.2(b)(5)(iii). On or after the Reversion Date, all Liens created during the Suspension Period will be considered Permitted Liens. Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 3.3 will be made as though Section 3.3 had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will reduce the amount available to be made as Restricted Payments under Section 3.3(a). As described above, however, no Default, Event of Default or breach of any kind shall be deemed to have occurred as a result of the Reversion Date occurring on the basis of any actions taken or the continuance of any circumstances resulting from actions taken or the performance of obligations under agreements entered into by the Issuers or any of the Restricted Subsidiaries during the Suspension Period (other than agreements to take actions after the Reversion Date that would not be permitted outside of the Suspension Period entered into in contemplation of the Reversion Date).

During the Suspension Period, no Restricted Subsidiary may be designated as an Unrestricted Subsidiary.

The Issuers, in an Officer’s Certificate, shall provide the Trustee notice of any Covenant Suspension or Reversion Date. The Trustee will have no obligation to (i) independently determine or verify if such events have occurred, (ii) make any determination regarding the impact of actions taken during the Suspension Period on the Issuers’ future compliance with their covenants or (iii) notify the Holders of a Covenant Suspension or Reversion Date.

SECTION 3.22. Trinseo Finance. Trinseo Finance shall not hold any material assets, become liable for any material obligations, engage in any trade or business, or conduct any business activity, other than (1) the Incurrence of Indebtedness as the co-obligor or guarantor, as the case may be, of the Notes and any other Indebtedness that is permitted to be Incurred by the Company under Section 3.2; provided, however, that the net proceeds of such Indebtedness are not retained by Trinseo Finance and (2) activities incidental thereto. Neither Holdings, the Company nor any of their Restricted Subsidiaries shall engage in any transactions with Trinseo Finance in violation of the immediately preceding sentence. Trinseo Finance shall be a Wholly-Owned Subsidiary of the Company that is a Domestic Subsidiary at all times. This Indenture also provides that for so long as the Company or any successor obligor under the Notes is a Person that is not incorporated in the United States of America, any State of the United States or the District of Columbia there will be a co-issuer of the Notes that is a Wholly-Owned Subsidiary of the Company (or such successor thereof) that is a Domestic Subsidiary.

Subject to the applicable limitations set forth in the Security Documents and this Indenture (including with respect to Excluded Assets), the Issuers and the Guarantors shall execute any and all further documents, financing statements, applications for registration, agreements and instruments, and take all further action that may be required under applicable law, or that the Collateral Agent may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the security interest created or intended to be created by the Security Documents in the Collateral.

From and after the Issue Date, upon the acquisition by an Issuer or any Guarantor of property which constitutes Collateral (“After-Acquired Collateral”), such Issuer or such Guarantor shall, within 90 days with respect to any Material Real Property, and to the extent required by this Indenture and/or the Security Documents with respect to all other After-Acquired Collateral, execute and deliver such security instruments, financing statements, certificates and opinions of counsel as shall be necessary to vest in the Collateral Agent a perfected security interest, subject only to Permitted Liens, in such After-Acquired Collateral and to have such After-Acquired Collateral added to the Collateral, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such After-Acquired Collateral to the same extent and with the same force and effect. The Issuers and the Guarantors may, in their reasonable discretion and in consultation with the Trustee and the Collateral Agent, extend such 90 day time period with respect to any such document to such longer time period as the such Issuers or such Guarantors reasonably believe in good faith is necessary to deliver such documents; provided that such Issuers and such Guarantors shall provide written notice of any such extension to the Trustee for the benefit of the Holders of the Notes, which notice shall describe in reasonable detail the Collateral to which the applicable documents apply and the length of such extension.

(a) keep their respective material insurable properties adequately (as reasonably determined by the Company) insured in all material respects at all times by financially sound and reputable insurers to such extent and against such risks, including fire and other risks insured against by extended coverage, as is customary with companies in the same or similar businesses operating in the same or similar locations; and

(b) within 60 days of the Issue Date (or such longer period as the Issuers may, in their reasonable discretion and in consultation with the Trustee and the Collateral Agent, reasonably believe in good faith is necessary) cause all such policies covering any Collateral to be endorsed or otherwise amended to include the Collateral Agent as an additional insured, loss payee or mortgagee, as applicable, and, to the extent available on commercially reasonable terms, cause each such policy to provide that it shall not be canceled, modified or not renewed (i) by reason of nonpayment of premium unless not less than 10 days’ prior written notice thereof is given by the insurer to the Collateral Agent (giving the Collateral Agent the right to cure defaults in the payment of premiums) or (ii) for any other reason unless not less than 30 days’ prior written notice thereof is given by the insurer to the Collateral Agent.

SECTION 3.25. Impairment of Security Interest. The Issuers shall not, and shall not permit any Restricted Subsidiary to (x) take or knowingly or negligently omit to take any action that would have the result of materially impairing the security interest with respect to the Collateral (it being understood, subject to the proviso below, that the Incurrence of Permitted Liens shall under no circumstances be deemed to materially impair the security interest with respect to the Collateral) for the benefit of the Collateral Agent, the Trustee and the Holders, or (y) grant to any Person other than the Collateral Agent or, if different, the collateral agent under any Payment Priority Obligations, Pari Passu Secured Obligations or Junior Secured Obligations that are subject to an Intercreditor Agreement, for the benefit of the Collateral Agent, the Trustee and the Holders and the other beneficiaries described in the Security Documents and any Intercreditor Agreement, and other than with respect to any Permitted Lien, any interest whatsoever in any of the Collateral, except that (i) the Issuers and the Restricted Subsidiaries may Incur Permitted Liens and the Collateral may be discharged and released in accordance with this Indenture, the applicable Security Documents or any Intercreditor Agreement and (ii) the applicable Security Documents may be amended from time to time to cure any ambiguity, mistake, omission, defect or inconsistency therein. Each of the Issuers and each Guarantor will, at its sole cost and expense, execute and deliver all such agreements and instruments as necessary, or as the Trustee or Collateral Agent reasonably requests, to more fully or accurately describe the assets and property intended to be Collateral or the obligations intended to be secured by the Security Documents.

SECTION 3.26. Post-Closing Obligations. The Issuers shall use their reasonable best efforts to deliver to the Initial Purchasers, the Trustee and the Collateral Agent the documents described in Schedule I within 90 days after the Closing Date. The Issuers may, in their reasonable discretion and in consultation with the Trustee and the Collateral Agent, extend such 90 day time period with respect to any such document to such longer time period as the Issuers reasonably believe in good faith is necessary to deliver such documents; provided that the Issuers shall provide written notice of any such extension to the Trustee and the Holders of the Notes, which notice shall describe in reasonable detail the Collateral to which the applicable documents apply and the length of such extension.

(a) Neither Issuer will consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets to, any Person, unless:

(1) the resulting, surviving or transferee Person (the “Successor Company”) will be a Person organized and existing under the laws of any member state of the European Union, the United States of America, any State of the United States or the District of Columbia and the Successor Company (if not either of the Issuers) will expressly assume, by supplemental indenture, amendment or other instrument executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company under the Notes, this Indenture, the Security Documents and any Intercreditor Agreement, and the Successor Company shall cause such amendments, supplements or other instruments to be executed, filed and recorded in such jurisdictions as may be required by applicable law to preserve and protect the Lien on the Collateral owned by or transferred and if such Successor Company is not a corporation, a co-obligor of the Notes is a corporation organized or existing under such laws;

(2) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Company or any Subsidiary of the Successor Company as a result of such transaction as having been Incurred by the Successor Company or such Subsidiary at the time of such transaction), no Default or Event of Default shall have occurred and be continuing;

(3) immediately after giving effect to such transaction, either (a) the Successor Company with respect to such Issuer would be able to Incur at least an additional $1.00 of Indebtedness pursuant to Section 3.2(a) hereof or (b) the Fixed Charge Coverage Ratio would not be lower than it was immediately prior to giving effect to such transaction; and

(4) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each to the effect that such consolidation, merger or transfer and such supplemental indenture, amendment or other instrument (if any) comply with this Indenture and an Opinion of Counsel to the effect that such supplemental indenture, amendment or other instrument (if any) has been duly authorized, executed and delivered and is a legal, valid and binding agreement enforceable against the Successor Company (in each case, in form reasonably satisfactory to the Trustee); provided that in giving an Opinion of Counsel, counsel may rely on an Officer’s Certificate as to any matters of fact, including as to satisfaction of clauses (2) and (3) above.

(b) For purposes of this Section 4.1, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

(c) The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, either Issuer under this Indenture, the Notes, the Security Documents and any Intercreditor Agreement, but in the case of a lease of all or substantially all its assets, the predecessor company will not be released from its obligations under this Indenture, the Notes, the Security Documents or any Intercreditor Agreement.

(d) Notwithstanding Section 4.1(a)(2), (a)(3) and (a)(4) (which do not apply to transactions referred to in this sentence), (i) any Restricted Subsidiary of the Company may consolidate or otherwise combine with, merge into or transfer all or part of its properties and assets to the Company and (ii) any Restricted Subsidiary may consolidate or otherwise combine with, merge into or transfer all or part of its properties and assets to any other Restricted Subsidiary. Notwithstanding Section 4.1(a)(2) and (a)(3) (which do not apply to the transactions referred to in this sentence), the Company may consolidate or otherwise combine with or merge into an Affiliate incorporated or organized for the purpose of changing the legal domicile of the Company, reincorporating the Company in another jurisdiction, or changing the legal form of the Company.

(e) The foregoing provisions (other than the requirements of Section 4.1(a)(2)) shall not apply to the creation of a new Subsidiary as a Restricted Subsidiary of the Company.

(2) sell, convey, transfer or dispose of, all or substantially all its assets, in one transaction or a series of related transactions, to, any Person; or

(i) the other Person is the Company or any Restricted Subsidiary that is a Guarantor or becomes a Guarantor concurrently with the transaction; or

(ii) (A) either (x) a Guarantor is the continuing Person or (y) the resulting, surviving or transferee Person (the “Successor Guarantor”) expressly assumes all of the obligations of the Guarantor under its Guarantee of the Notes and the Security Documents and any Intercreditor Agreement and the Successor Guarantor shall cause such amendments, supplements or other instruments to be executed, filed and recorded in such jurisdiction as may be required by applicable law to preserve and protect the Lien in the Collateral owned by or transferred to such Successor Guarantor; and

(B) immediately after giving effect to the transaction, no Default has occurred and is continuing; or

(iii) the transaction constitutes a sale or other disposition (including by way of consolidation or merger) of the Guarantor or the sale or disposition of all or substantially all the assets of the Guarantor (in each case other than to the Company or a Restricted Subsidiary) otherwise permitted by this Indenture.

SECTION 5.1. Notices to Trustee. If the Issuers elect to redeem Notes pursuant to the optional redemption provisions of Section 5.7 hereof, they must furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officer’s Certificate setting forth:

Any optional redemption referenced in such Officer’s Certificate may be canceled by the Issuers at any time prior to notice of redemption being sent to any Holder and thereafter shall be null and void.

SECTION 5.2. Selection of Notes to Be Redeemed or Purchased. If less than all of the Notes are to be redeemed pursuant to Section 5.7 or purchased in an Asset Disposition Offer pursuant to Section 3.5 or a redemption pursuant to Section 5.9, the Trustee will select Notes for redemption or purchase (a) if the Notes are in global form, on a pro rata basis or by lot or such similar method in accordance with the procedures of DTC and (b) if the Notes are in definitive form, on a pro rata basis (subject to adjustments to maintain the authorized Notes denomination requirements) except:

(1) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or

No Notes in an unauthorized denomination or less than $2,000 in aggregate principal amount shall be redeemed in part. In the event of partial redemption, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee will promptly notify the Issuers in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

SECTION 5.3. Notice to Redemption. Except in the case of redemptions due to changes in tax law (for which the time frame will be as set forth in Section 5.9), at least 30 days but not more than 60 days before a redemption date, the Issuers will send or cause to be delivered electronically or mailed by first class mail postage prepaid, a

notice of redemption to each Holder whose Notes are to be redeemed at its registered address or otherwise in accordance with the procedures of DTC, except that redemption notices may be delivered electronically or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article VIII or XI hereof.

The notice will identify the Notes (including the CUSIP or ISIN number) to be redeemed and will state:

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

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

(6) that, unless the Issuers default in making such redemption payment, interest and Additional Interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date;

(7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Issuers’ request, the Trustee will give the notice of redemption in the Issuers’ name and at its expense; provided, however, that the Issuers have delivered to the Trustee, at least 45 days prior to the redemption date (or such shorter period as is acceptable to the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

SECTION 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, including, but not limited to, completion of an Equity Offering (in the case of redemption pursuant to Section 5.7(b) hereof) or Change of Control (in the case of purchase pursuant to Section 3.9 hereof), as the case may be.

SECTION 5.5. Deposit of Redemption or Purchase Price. Prior to 10:00 a.m. Eastern 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 and Additional Interest, if any, on, all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest and Additional Interest, if any, on, all Notes to be redeemed or purchased.

If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest and Additional Interest, if any, 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 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 multiple of $1,000 in excess thereof.

(a) At any time prior to August 1, 2015, the Issuers may redeem the Notes in whole or in part, at their option, upon not less than 30 nor more than 60 days’ prior notice at a redemption price equal to 100.000% of the principal amount of such Notes plus the relevant Applicable Premium as of, and accrued and unpaid interest and Additional Interest, if any, to the redemption date.

(b) At any time and from time to time on or after August 1, 2015, the Issuers may redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days’ notice at a redemption price equal to the percentage of principal amount set forth below plus accrued and unpaid interest, if any, on the Notes redeemed to the applicable date of redemption, if redeemed during the twelve-month period beginning on the year indicated below:

(c) At any time and from time to time prior to August 1, 2015, the Issuers may redeem Notes with the net cash proceeds received by the Issuers from any Qualified Equity Offering at a redemption price equal to 108.750% plus accrued and unpaid interest to the redemption date, in an aggregate principal amount for all such redemptions not to exceed 35% of the original aggregate principal amount of the Notes (including Additional Notes); provided that

(1) In each case the redemption takes place not later than 180 days after the closing of the related Qualified Equity Offering, and

(2) not less than 50% of the original aggregate principal amount of the Notes issued under this Indenture (including any Additional Notes) remains outstanding immediately thereafter (excluding Notes held by the Company or any of its Restricted Subsidiaries).

(d) In addition, at any time and from time to time prior to August 1, 2015, the Issuers may redeem up to 10% of the original principal amount of the Notes issued under this Indenture (including any Additional Notes) during each twelve-month period commencing with the Issue Date at a redemption price of 103% of the aggregate principal amount thereof plus accrued and unpaid interest to the redemption date.

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

(g) 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. The Issuers are not required to make mandatory redemption or sinking fund payments with respect to the Notes; provided, however, that under certain circumstances, the Issuers may be required to offer to purchase Notes under Section 3.5 and Section 3.9. The Issuers may at any time and from time to time purchase Notes in the open market or otherwise.

SECTION 5.9. Tax Redemption. 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 30 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 the redemption date, premium, if any, and all Additional Amounts, if any, then due and which will become due on the date of redemption as a result of the redemption or otherwise, if the Issuers determine in good faith that the Issuers 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 the Issuers 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:

(a) any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of any Relevant Taxing Jurisdiction affecting taxation which 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

(b) 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) and (b), a “Change in Tax Law”).

Notwithstanding the foregoing, the Issuers may not redeem the Notes under this provision 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 which was officially announced at the time the latter became a Relevant Taxing Jurisdiction.

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 the Indenture. In the case of Additional Amounts required to be paid as a result of the Issuers conducting business in any jurisdiction (an “Additional Taxing 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.

Notwithstanding the foregoing, no such notice of redemption will be given (a) 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 Guarantee, as the case may be, were then due and (b) unless at the time such notice is given, the obligation to pay Additional Amounts remains in effect.

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.

Prior to the mailing of any notice of redemption pursuant to this Section 5.9, the Issuers will deliver to the Trustee:

(a) an Officer’s Certificate stating that the Issuers are entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Issuers so to redeem have occurred (including that such obligation to pay such Additional Amounts cannot be avoided by the Issuers or any Guarantor or surviving entity taking reasonable measures available to it); and

(b) a written opinion of independent legal counsel of recognized standing qualified under the laws of the Relevant Taxing Jurisdiction and reasonably satisfactory to the Trustee to the effect that the Issuers or a Guarantor or surviving entity, as the case may be, is or would be obligated to pay such Additional Amounts as a result of a Change in Tax Law.

The Trustee will accept, and shall be entitled to rely on, such Officer’s Certificate and opinion as sufficient evidence of the satisfaction of the conditions precedent described above, without further inquiry.

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.

SECTION 6.1. Events of Default. Each of the following is an “Event of Default”:

(1) default in any payment of interest, if any, on any Note when due and payable, continued for 30 days;

(2) default in the payment of the principal amount of or premium, if any, on any Note issued under this Indenture when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise;

(3) failure to comply with the Issuers’ agreements or obligations contained in this Indenture for 60 days after written notice by the Trustee on behalf of the Holders or by the Holders of at least 30% in principal amount of the outstanding Notes;

(4) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is Guaranteed by the Company or any of its Restricted Subsidiaries), other than Indebtedness owed to the Company or any of its Restricted Subsidiaries whether such Indebtedness or Guarantee now exists or is created after the date hereof, which default:

(A) is caused by a failure to pay principal of such Indebtedness, at its stated final maturity (after giving effect to any applicable grace periods provided in such Indebtedness); or

(B) results in the acceleration of such Indebtedness prior to its stated final maturity;

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a payment default or the maturity of which has been so accelerated, aggregates $75.0 million or more;

(5) failure by the Issuers or any Significant Subsidiary (or group of Restricted Subsidiaries that together (determined as of the most recent consolidated financial statements of the Company for a fiscal period end provided as required under Section 3.10) would constitute a Significant Subsidiary), to pay final judgments aggregating in excess of $75.0 million other than any judgments covered by indemnities provided by, or insurance policies issued by, reputable and creditworthy companies, which final judgments

remain unpaid, undischarged and unstayed for a period of more than 60 days after such judgment becomes final, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed;

(6) any Note Guarantee ceases to be in full force and effect, other than in accordance with the terms of this Indenture or a Guarantor denies or disaffirms its obligations under its Note Guarantee, other than in accordance with the terms of this Indenture or upon release of such Guarantee in accordance with this Indenture;

(7) any Security Document shall for any reason (other than pursuant to the terms thereof including as a result of a transaction not prohibited by this Indenture) cease to create a valid and perfected lien, with the priority required by the Security Documents or any security interest in any material portion of the Collateral purported to be covered thereby, subject to Permitted Liens, (i) except to the extent that any such perfection or priority is not required pursuant to this Indenture or Security Documents or results from the failure of the Collateral Agent to maintain possession of certificates actually delivered to it representing securities pledged under the Security Documents and (ii) except as to Collateral consisting of Material Real Property to the extent that such losses are covered by a lender’s title insurance policy and such insurer has not denied coverage;

(8) the failure by the Issuers or any Guarantor to comply for 60 days after notice with its other agreements contained in the Security Documents, except for a failure that would not be material to the Holders of the Notes and would not materially affect the value of the Collateral taken as a whole (together with the defaults described in clauses (7) and (8) the “security default provisions”).

(9) the Issuers or any Guarantor that is 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 pursuant to or within the meaning of any Bankruptcy Law:

(B) consents to the entry of an order for relief against it in an involuntary case or proceeding;

(E) consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against it; or

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

(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;

(D) any similar relief is granted under any foreign laws and the order, decree or relief remains unstayed and in effect for 60 consecutive days;

(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; or

(F) a German Insolvency Event occurs in relation to any Guarantor organized under the laws of the Federal Republic of Germany that is a Significant Subsidiary.

SECTION 6.2. Acceleration. If any Event of Default (other than an Event of Default described in clause (9) or (10) of Section 6.1) occurs and is continuing, the Trustee by notice to the Issuers, or 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 and Additional Interest, if any, on all the Notes to be immediately due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest, including Additional Interest, if any, will be due and payable immediately.

In the event of any Event of Default specified in clause (4) of Section 6.1, 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

(b) all existing Events of Default, except nonpayment of principal, premium or interest, including Additional Interest, if any, 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 (9) or (10) of Section 6.1 occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest, including Additional Interest, if any, 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.

SECTION 6.3. Other Remedies. If an Event of Default occurs and is continuing, the Trustee or Collateral Agent 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, including Additional Interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee or Collateral Agent 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.

In addition to the right of acceleration set forth in Section 6.2 hereof, if an Event of Default occurs and is continuing under this Indenture, the Trustee or the Collateral Agent, as applicable, shall, subject to the provisions contained in the Intercreditor Agreement, have the right to exercise remedies with respect to the Collateral such as foreclosure, as are available under this Indenture, the Security Documents and at law.

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 or the Security Documents except (i) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest, including Additional Interest, if any, 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, interest or Additional Interest, if any, 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, Additional Interest, if any, 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, 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 of conducting any proceeding for any remedy available to the Trustee or the Collateral Agent or of exercising any trust or power conferred on the Trustee or the Collateral Agent. However, the Trustee and the Collateral Agent may refuse to follow any direction that conflicts with law or this Indenture or the Notes or, subject to Sections 7.1 and 7.2, that the Trustee or the Collateral Agent determines is unduly prejudicial to the rights of other Holders or would involve the Trustee or the Collateral Agent in personal liability; provided, however, that the Trustee or 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 or the Collateral Agent shall be entitled to indemnification satisfactory to it 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. Subject to Section 6.7, a Holder may not pursue any remedy with respect to this Indenture, the Notes or the Collateral unless:

(1) such Holder has previously given the Trustee or the Collateral Agent, as applicable, 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 the Trustee security 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 or indemnity; and

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

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, including Additional Interest, if any, 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 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 Additional Interest, if any, to the extent lawful) and the amounts provided for in Section 7.7.

SECTION 6.9. Trustee May File Proofs of Claim. 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 (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the 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, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7.

No provision of this Indenture shall be deemed to authorize the Trustee to or Collateral Agent authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

(a) If the Trustee or Collateral Agent collects any money or property pursuant to this Article VI it shall, subject to the Intercreditor Agreement, pay out the money or property in the following order:

FIRST: to the Trustee or the Collateral Agent for amounts due to them under Section 7.7;

SECOND: to Holders for amounts due and unpaid on the Notes for principal of, or premium, if any, and interest and Additional Interest, if any, 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 (including Additional Interest), respectively; and

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 for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party

litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by 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.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture, the Notes, the Security Agreement, the Intercreditor Agreement and any other Security Document and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(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

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates, opinions or orders furnished to the Trustee and conforming to the requirements of this Indenture or the Notes, as the case may be. 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;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts;

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5; and

(4) No provision of this Indenture or the Notes shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or there-under or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to clauses (a), (b) and (c) of this Section 7.1.

(e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuers.

(f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.1 and to the provisions of the TIA.

(a) The Trustee may conclusively rely on and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document (whether in its original or facsimile form) reasonably believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. 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) 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.

(c) The Trustee may execute any of the trusts and powers hereunder or perform any duties hereunder either directly or through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent or attorney appointed with due care by it hereunder.

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers conferred upon it by this Indenture.

(e) The Trustee may consult with counsel of its selection, and the advice or opinion of counsel relating to this Indenture or the Notes shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder or under the Notes in good faith and in accordance with the advice or opinion of such counsel.

(f) 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 a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default or of any such Significant Subsidiary is received by the Trustee at the corporate trust office of the Trustee specified in Section 3.12, and such notice references the Notes and this Indenture.

(g) 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.

(h) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture or the Notes at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred therein or thereby.

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

(j) Whenever in the administration of this Indenture or the Notes the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder or thereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith or willful misconduct on its part, conclusively rely upon an Officer’s Certificate.

(k) 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.

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

(m) The Trustee may request that the Issuers deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture or the Notes.

(s) The Trustee shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens upon any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part.

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 Sections 7.10 and 7.11. In addition, the Trustee shall be permitted to engage in transactions with the Issuers; provided, however, that if the Trustee acquires any conflicting interest under the TIA, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the SEC for permission to continue acting as Trustee or (iii) resign.

SECTION 7.4. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Collateral, the Security Documents 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 paid to the Issuers pursuant to the terms of this Indenture and shall not be responsible for 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.

SECTION 7.5. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual knowledge 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 it is actually known to a Trust Officer. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, interest or Additional Interest, if any, 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 January 31 beginning January 31, 2014, the Trustee shall mail to each Holder a brief report dated as of such January 31 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).

A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange (if any) on which the Notes are listed. The Issuers agree to notify the Trustee promptly in writing whenever the Notes become listed on any stock exchange and of any delisting thereof and the Trustee shall comply with TIA Section 313(d).

SECTION 7.7. Compensation and Indemnity. For the purposes of this Section 7.7, the Trustee and the Collateral Agent are referred to collectively as the “Indemnified Parties,” and each as an “Indemnified Party.” The Company shall pay to the Trustee from time to time such compensation with respect to the Trustee, for its acceptance of this Indenture and services hereunder and, with respect to the Collateral Agent, for its acceptance of the Security Agreement and services thereunder, as the parties shall agree in writing from time to time. The Trustee’s and the 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. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s and the Collateral Agent’s agents and counsel.

The Issuers and the Guarantors, jointly and severally, shall indemnify each Indemnified Party and its officers, directors, employees, agents and any predecessor trustee or collateral agent and their respective officers, directors, employees and agents 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 it in connection with the acceptance or administration of this trust and the performance of its duties hereunder or under the Security Documents (including the reasonable costs and expenses of enforcing this Indenture or the Security Documents 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 or under the Security Documents) (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 through the Trustee’s own willful misconduct, negligence or bad faith or incurred by the Collateral Agent through the Collateral Agent’s own willful misconduct, gross negligence or bad faith, in each case 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.

The obligations of the Company under this Section 7.7 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee or the Collateral Agent, as applicable.

Notwithstanding anything to the contrary in Section 3.6 hereof, to secure the payment obligations of the Issuers and the Guarantors in this Section 7.7, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except 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.

When the Trustee and Collateral Agent incur expenses or render services after an Event of Default specified in Section 6.1(9) or Section 6.1(10) 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. 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:

(3) a receiver or other public officer takes charge of the Trustee or its property; or

If the Trustee resigns or is removed by the Issuers or by the Holders of a majority in principal amount of the Notes and such Holders do not reasonably promptly appoint a successor Trustee as described in the preceding paragraph, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Issuers shall promptly appoint a successor Trustee.

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.

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.

If the Trustee fails to comply with Section 7.10, unless the Trustee’s duty to resign is stayed as provided in TIA Section 310(b), 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.

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. 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 without any further act shall be the successor Trustee.

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. Intercreditor Agreement and the Security Documents. The Trustee is hereby directed and authorized by the Holders to execute and deliver, or cause the Collateral Agent to execute and deliver, the Inter-creditor Agreement and any other Security Documents to the extent it is named as a party therein. Whether or not so expressly stated therein, in entering into, or taking (or forbearing from) any action under or pursuant to, the Inter-creditor Agreement or any other Security Document, the Trustee and the Collateral Agent each shall have all of the rights, immunities, indemnities and other protections granted to it under this Indenture (in addition to those that may be granted to it under the terms of such other agreement or agreements). Each Holder, by its acceptance of a Note, hereby authorizes the Collateral Agent to execute and deliver the Intercreditor Agreement for the benefit of the Holders and make the representations of such Holder set forth therein, and each Holder agrees to be bound by all of the provisions of the Intercreditor Agreement. In addition, each Holder acknowledges and agrees that the Collateral Agent has entered into the Intercreditor Agreement and other Security Documents for the benefit of the Holders and agrees to be bound by all of the provisions thereof.

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.

SECTION 8.1. Option to Effect Legal Defeasance or Covenant Defeasance; Defeasance. The Issuers may, at their option and at any time, elect to have either Section 8.2 or 8.3 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII.

SECTION 8.2. Legal Defeasance and Discharge. Upon the Issuers’ exercise under Section 8.1 hereof of the option applicable to this Section 8.2, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the 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 Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all of their other obligations under such Notes, the Guarantees and this Indenture and the Security Documents (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, and interest and Additional Interest, if any, on the Notes when such payments are due solely out of the trust referred to in Section 8.4 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 3.12 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

SECTION 8.3. Covenant Defeasance. Upon the Issuers’ exercise under Section 8.1 hereof of the option applicable to this Section 8.3, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be released from each of their obligations under the covenants contained in Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.16, 3.19, 3.21, 3.24 and 4.1 (except Sections 4.1(a)(1) and (a)(2)) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.4 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 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 Guarantees will be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.1 hereof of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, Sections 6.1(3) (other than with respect to Sections 4.1(a)(1) and (a)(2)), 6.1(4), 6.1(5), 6.1(6), 6.1(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), and 6.1(10) (with respect only to a Guarantor that is a Significant Subsidiary or any group of Guarantors that taken together would constitute a Significant Subsidiary) hereof shall not constitute Events of Default.

SECTION 8.4. Conditions to Legal or Covenant Defeasance. In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.2 or 8.3 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, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of and premium, if any, interest and Additional Interest, if any, 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;

(2) in the case of Legal Defeasance, the Issuers shall have delivered to the Trustee an Opinion of Counsel in the United States confirming that, subject to customary assumptions and exclusions;

(A) the Issuers have received from, or there has been published by, the United States Internal Revenue Service a ruling; or

(B) since the issuance of such Notes, there has been a change in the applicable U.S. federal income tax law;

in either case stating that, and based thereon such Opinion of Counsel in the United States 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 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 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 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 8.5. Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.6 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 8.5, the “Trustee”) pursuant to Section 8.4 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 and Additional Interest, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Obligations deposited pursuant to Section 8.4 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. The indemnity contained herein shall survive discharge of the Indenture and any resignation or removal of the Trustee.

Notwithstanding anything in this Article VIII to the contrary, the Trustee will deliver or pay to the Issuers from time to time upon the request of the Issuers any money or U.S. Government Obligations held by it as provided in Section 8.4 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.4(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.6. Repayment to the Issuers. Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium or Additional Interest, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium or Additional Interest, if any, or interest has become due and payable shall be paid to the Issuers on their written request unless an abandoned property law designates another Person or (if then held by the Issuers) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuers for payment thereof unless an abandoned property law designates another Person, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense of the Issuers cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuers.

SECTION 8.7. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. dollars or U.S. Government Obligations in accordance with Section 8.2 or 8.3 hereof, as the case may be, by reason of any order or judgment of any court or Governmental Authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ and the Guarantors’ obligations under this Indenture and the Notes and the Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.2 or 8.3 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2 or 8.3 hereof, as the case may be; provided, however, that, if the Issuers make any payment of principal of, premium or Additional Interest, if any, or interest on, any Note following the reinstatement of its obligations, the Issuers will 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.

SECTION 9.1. Without Consent of Holders. Notwithstanding Section 9.2 hereof, without the consent of any Holder, the Issuers, the Trustee and, to the extent applicable, the Collateral Agent may amend or supplement any Note Documents or Security Documents and the Issuers may direct the Trustee and the Collateral Agent, and the Trustee and Collateral Agent shall, enter into an amendment to the Intercreditor Agreement or any Future Intercreditor Agreement, to:

(1) cure any ambiguity, omission, mistake, defect, error or inconsistency or reduce the minimum denomination of the Notes;

(2) provide for the assumption by a successor Person of the obligations of the Issuers or any Guarantor under any Note Document;

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

(4) add to the covenants or provide for a Note Guarantee for the benefit of the Holders or surrender any right or power conferred upon the Company or any Restricted Subsidiary;

(5) make any change that does not adversely affect the rights of any Holder in any material respect;

(6) make such provisions as necessary (as determined in good faith by the Company) for the issuance of Additional Notes in accordance with the terms of this Indenture;

(7) provide for any Restricted Subsidiary to provide a Note Guarantee in accordance with Section 3.2, to add Guarantees with respect to the Notes, to add security to or for the benefit of the Notes, or to confirm and evidence the release, termination, discharge or retaking of any Guarantee or Lien with respect to or securing the Notes when such release, termination, discharge or retaking is provided for under this Indenture;

(8) evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee pursuant to the requirements hereof or to provide for the accession by the Trustee to any Note Document;

(9) make any amendment to the provisions of this Indenture relating to the transfer and legending of Notes as permitted by this Indenture, including, without limitation, to facilitate the issuance and administration of Notes; provided, however, that (i) compliance with this Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and adversely affect the rights of Holders to transfer Notes;

(10) mortgage, pledge, hypothecate or grant any other Lien in favor of the Trustee or the Collateral Agent for the benefit of the Collateral Agent, the Trustee, the Holders of the Notes and any holders of Pari Passu Secured Obligations, as additional security for the payment and performance of all or any portion of the Notes Obligations or any Pari Passu Secured Obligations subject to the Security Documents in any property or assets, including any which are required to be mortgaged, pledged or hypothecated, or in which a Lien is required to be granted to or for the benefit of the Trustee or the Collateral Agent pursuant to this Indenture, any of the Security Documents or otherwise, in each case as certified in an Officer’s Certificate;

(11) provide for the release of Collateral from the Lien pursuant to this Indenture, the Security Documents, the Intercreditor Agreement and any Future Intercreditor Agreement when permitted or required by the Security Documents, this Indenture, the Intercreditor Agreement or any Future Intercreditor Agreement, in each case as certified in an Officer’s Certificate; or

(12) provide for the succession of parties (other than the Issuers and the Guarantors) to the Security Documents, and other changes that are ministerial and administrative in nature, in connection with any refinancing, amendment, renewal, extension, substitution, restructuring, replacement, supplement or other modification of any agreement governing Pari Passu Secured Obligations and to which such parties are bound, in each case solely to the extent not prohibited by this Indenture; or

(13) conform the text of this Indenture, the Notes, the Note Guarantees, the Security Documents or the Intercreditor Agreement to any provision under the heading “Description of Notes” in the Offering Memorandum to the extent that such provision under the heading “Description of Notes” in the Offering Memorandum is intended to be a verbatim recitation or a summary of a provision of this Indenture, the Notes, the Note Guarantees, the Security Documents or the Intercreditor Agreement as certified in an Officer’s Certificate.

In connection with any amendment, the Trustee shall be entitled to receive an Officer’s Certificate and Opinion of Counsel each stating that such amendment is authorized or permitted by the terms of this Indenture, the Credit Agreement and each agreement governing any Pari Passu Secured Obligations, as applicable, and that all conditions precedent to such amendment required by this Indenture, the Credit Agreement and each agreement governing any Pari Passu Secured Obligations, as applicable, have been complied with.

Subject to Section 9.2, upon the request of the Issuers and upon receipt by the Trustee and Collateral Agent, if applicable, of the documents described in Sections 9.6 and 13.4 hereof, the Trustee and Collateral Agent, if applicable,

will join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture or other Notes Document unless such amended or supplemental indenture or other Notes Document affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture.

After an amendment or supplement under this Section 9.1 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 under this Section 9.1.

SECTION 9.2. With Consent of Holders. Except as provided below in this Section 9.2, the Issuers, the Guarantors, the Trustee and, to the extent applicable, the Collateral Agent may amend or supplement this Indenture, any Guarantee, the Notes issued hereunder the Intercreditor Agreement or any Security Document (together, the “Notes Documents”) with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding and issued under this Indenture, including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes, and, subject to Sections 6.4 and 6.7 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, and Additional Interest, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes, the Guarantees and the Security Documents may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes issued under this Indenture (including consents obtained in connection with a purchase of or tender offer or exchange offer for Notes). Section 2.12 hereof and Section 13.6 hereof shall determine which Notes are considered to be “outstanding” for the purposes of this Section 9.2.

Upon the request of the Issuers accompanied by a resolution of their Boards of Directors authorizing the execution of any such amended or supplemental indenture or other Notes Document, and upon the filing with the Trustee of evidence of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Sections 9.6 and 13.4 hereof, the Trustee (and the Collateral Agent to the extent a party to the applicable document) will join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture or other Notes Document unless such amended or supplemental indenture or other Notes Document affects the Trustee’s or the Collateral Agent’s, as applicable, own rights, duties or immunities under this Indenture or other Notes Document or otherwise, in which case the Trustee (and the Collateral Agent to the extent a party to the applicable document) may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture or other Notes Document.

Without the consent of each Holder of Notes affected, an amendment, supplement or waiver may not, with respect to any Notes issued thereunder and held by a nonconsenting Holder:

(1) reduce the principal amount of such Notes whose Holders must consent to an amendment;

(2) reduce the stated rate of or extend the stated time for payment of interest on any such Note (other than provisions relating to Section 3.5 and Section 3.9);

(4) reduce the premium payable upon the redemption of any such Note or change the time at which any such Note may be redeemed, in each case as set forth in Section 5.7;

(6) impair the right of any Holder to receive payment of principal of and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any such payment on or with respect to such Holder’s Notes;

(7) waive a Default or Event of Default with respect to the nonpayment of principal, premium or interest (except pursuant to a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of such Notes and a waiver of the payment default that resulted from such acceleration);

(8) make any change in the amendment or waiver provisions which require the Holders’ consent described in this Section 9.2.

In addition, without the consent of the Holders of at least 66 2/3% in principal amount of Notes then outstanding, no amendment, supplement or waiver may (i) release all or substantially all of the Collateral from the Liens of the Security Documents (except as permitted by the terms of this Indenture and the Security Documents) or (ii) make any change in this Indenture, any Security Document, the Intercreditor Agreement or any Future Intercreditor Agreement that has the effect of altering the priority of the liens or the application of proceeds of the Collateral in a manner that would adversely affect the Holders in any material respect.

It shall not be necessary for the consent of the Holders under this Indenture to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. A consent to any amendment, supplement or waiver under this Indenture by any Holder of the Notes given in connection with a tender or exchange of such Holder’s Notes will not be rendered invalid by such tender or exchange.

After an amendment or supplement under this Section 9.2 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 9.3. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture, any Guarantee and the Notes will be set forth in an amended or supplemental indenture that complies with the TIA as then in effect.

SECTION 9.4. Revocation and Effect of Consents and Waivers. 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.

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 9.5. Notation on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The 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.

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 9.6. Trustee to Sign Amendments. The Trustee shall sign any amended or supplemental indenture or amendment to other Notes Document authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The 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 Sections 7.1 and 7.2 hereof) shall be fully protected in conclusively relying upon, in addition to the documents required by Section 13.4 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.

SECTION 10.1. Guarantee. Subject to the provisions of this Article X, 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 (including Additional Interest) on the Notes and all other obligations and liabilities of the Issuers under this Indenture (including without limitation interest (including Additional 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), and the Registration Rights Agreement (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 to the extent such other Indebtedness is subordinate to the Guaranteed Obligations, in which case the obligations of the Guarantors under the Guarantees will rank senior in right of payment to such other Indebtedness.

To evidence its Guarantee set forth in this Section 10.1, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an Officer of such Guarantor.

Each Guarantor hereby agrees that its Guarantee set forth in this Section 10.1 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

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

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 X notwithstanding any extension or renewal of any Guaranteed Obligation.

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.

Each Guarantor further agrees that its 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.

Except as set forth in Section 10.2, 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.

Each Guarantor agrees that its 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 Guarantee in compliance with Section 10.2, Article VIII or Article XI. Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium, if any, interest or Additional Interest, if any, 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.

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 (including Additional 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).

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 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 Guarantee.

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

The Guarantee set forth in this Section 10.1 is a continuing guarantee of payment and shall apply to all Guaranteed Obligations whenever arising.

(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 Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its 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 of a Guarantor shall be automatically and unconditionally released and discharged upon:

(1) a sale or other disposition (including by way of consolidation or merger) of the Capital Stock of such Guarantor or the sale or disposition of all or substantially all the assets of the Guarantor (other than to the Issuers or a Restricted Subsidiary) 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 VIII or Article XI;

(4) to the extent that such Guarantor is not an Immaterial Subsidiary solely due to the operation of clause (i) of the definition of “Immaterial Subsidiary,” upon the release of the guarantee referred to in such clause;

(5) to the extent such Guarantor is also a guarantor or borrower under the Credit Agreement as in effect on the Issue Date and, at the time of release of its Guarantee, (x) has been released from its guarantee of, and all pledges and security, if any, granted in connection with the Credit Agreement (except a release by or as a result of a payment thereon), (y) is not an obligor under any Indebtedness (other than Indebtedness permitted to be Incurred pursuant to Section 3.2(b)(3)) and (z) does not guarantee any Indebtedness of the Company or any of the Guarantors; or

(6) upon the achievement of Investment Grade Status by the Notes; provided that such Note Guarantee shall be reinstated upon the Reversion Date.

(c) To the extent that the jurisdiction of formation of any Guarantor that becomes party to this Indenture requires additional local law provisions with respect to such new Guarantor’s Guarantee obligations, such provisions shall be set out in the supplemental indenture and shall be deemed incorporated by reference into this Section 10.2. 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.

SECTION 10.3. 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 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 10.3 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 10.4. 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 10.5. Execution of Supplemental Indenture for Future Guarantors. Each Subsidiary and other Person which is required to become a Guarantor pursuant to Section 3.7, subject to Section 10.2 hereof, shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit D hereto pursuant to which such Subsidiary or other Person shall become a Guarantor under this Article X 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.

SECTION 11.1. Satisfaction and Discharge. This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when:

(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 of interest, 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 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) 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

(e) the Issuers have delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of such Notes issued hereunder at maturity or the redemption date, as the case may be.

In addition, the Issuers shall deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to clause (a)(2) of this Section 11.1, the provisions of Sections 8.6 and 11.2 hereof will survive.

SECTION 11.2. Application of Trust Money. Subject to the provisions of Section 8.6 hereof, all money deposited with the Trustee pursuant to Section 11.1 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 and Additional Interest, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 11.1 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 11.1 hereof; provided that if the Issuers have made any payment of principal of, premium or Additional Interest, 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.

(a) The payment of the principal of and interest and premium, if any, on the Notes when due, whether at maturity, by acceleration, repurchase, redemption or otherwise and whether by the Issuers pursuant to the Notes or by the Guarantors pursuant to the Guarantees, the payment of all other Notes Obligations and the performance of all other Notes Obligations of the Issuers and the Guarantors under this Indenture, the Notes, the Guarantees and the Security Documents are secured as provided in the Security Documents which the Issuers and the Guarantors have entered into and will be secured by Security Documents hereafter delivered as required or permitted by this Indenture. The Issuers shall, and shall cause each Guarantor to, and each Guarantor shall, make all filings (including filings of continuation statements and amendments to Uniform Commercial Code (or other personal property security legislation) financing statements that may be necessary to continue the effectiveness of such Uniform Commercial Code (or other personal property security legislation) financing statements) and all other actions as are necessary or required by the Security Documents to maintain (at the sole cost and expense of the Issuers and the Guarantors) the security interest created by the Security Documents in the Collateral (other than with respect to any Collateral the security interest in which is not required to be perfected or maintained under the Security Documents) as a perfected security interest subject only to Liens permitted by Section 3.6.

(1) the Capital Stock and other securities of the Company or any Subsidiary of the Company that are owned by the Issuers or any Guarantor shall constitute Collateral only to the extent that such Capital Stock and other securities can secure the Notes and Pari Passu Indebtedness without Rule 3-16 of Regulation S-X under the Securities Act (“Rule 3-16”) (or any other law, rule or regulation) requiring separate financial statements of such Subsidiary to be filed with the SEC (or any other governmental agency) (the “Rule 3-16 Exception”);

(2) in the event that Rule 3-16 requires or is amended, modified or interpreted by the SEC to require (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would require) the filing with the SEC (or any other governmental agency) of separate financial statements of any Subsidiary of the Issuers, due to the fact that such Subsidiary’s Capital Stock and other securities secure the Notes and/or Pari Passu Indebtedness, then the Capital Stock and other securities of such Subsidiary shall automatically be deemed not to be part of the Collateral (but only to the extent necessary to not be subject to such requirement) and in such event, the Security Documents may be amended or modified, without the consent of any Holder or a holder of Pari Passu Indebtedness, to the extent necessary to release the security interests in the shares of Capital Stock and other securities that are so deemed to no longer constitute part of the Collateral; and

(3) in the event that Rule 3-16 is amended, modified or interpreted by the SEC to permit (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would permit) the Company’s or such Subsidiary’s Capital Stock and other securities to secure the Notes and/or Pari Passu Indebtedness in excess of the amount then pledged without the filing with the SEC (or any other governmental agency) of separate financial statements of the Issuer or such Subsidiary, then the Capital Stock and other securities of the Company or of such Subsidiary shall automatically be deemed to be a part

of the Collateral (but only to the extent permitted without becoming subject to any such financial statement requirements). In such event, the Security Documents may be amended or modified, without the consent of any Holder or holders of Pari Passu Lien Indebtedness, to the extent necessary to subject to the Liens under the Security Documents such additional Capital Stock and other securities and the Company or such Subsidiary shall take all actions necessary to perfect such Liens.

Notwithstanding the foregoing, any such Capital Stock excluded as Collateral under the Rule 3-16 Exception will not be excluded from the collateral securing the Credit Agreement as a result of being excluded as Collateral.

(a) The Trustee and each of the Holders by acceptance of the Notes hereby designates and appoints the Collateral Agent as its agent (or, if applicable, as security trustee in accordance with the terms of any security trustee deed to be entered into in connection with the Security Documents) under this Indenture and the Security Documents and the Trustee and each of the Holders by acceptance of the Notes hereby irrevocably authorizes the Collateral Agent to take such action on its behalf under the provisions of this Indenture and the Security Documents and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Security Documents, together with such powers as are reasonably incidental thereto. The provisions of this Section 12.2 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders nor any of the Guarantors shall have any rights as a third party beneficiary of any of the provisions contained herein other than as expressly provided in Section 12.5. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the Security Documents, the Collateral Agent shall not have any duties or responsibilities hereunder nor shall the Collateral Agent have or be deemed to have any fiduciary relationship with the Trustee, any Holder or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Security 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. The Collateral Agent shall act pursuant to the instructions of the Holders and the Trustee with respect to the Security Documents and the Collateral. For the avoidance of doubt, the Collateral Agent shall have no discretion under this Indenture, the Intercreditor Agreement or the Security Documents and shall not be required to make or give any determination, consent, approval, request or direction without the written direction of the Holders of a majority in aggregate principal amount of the then outstanding Notes or the Trustee, as applicable. After the occurrence of an Event of Default, the Trustee may direct the Collateral Agent in connection with any action required or permitted by this Indenture, the Security Documents or the Intercreditor Agreement.

(b) None of the Collateral Agent or any of its respective Affiliates shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own gross negligence or willful misconduct) or under or in connection with any Collateral Document or the transactions contemplated thereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any of the Trustee or any Holder for any recital, statement, representation, warranty, covenant or agreement made by the Issuers or any Guarantor or Affiliate of any Issuer, any Guarantor, or any officer or Affiliate thereof, contained in this or any Indenture, any Security Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this or any other Indenture or the Security Documents, or the validity, effectiveness, genuineness, enforceability or sufficiency of this or any other Indenture or the Security Documents, or for any failure of any Guarantor or any other party to this Indenture or the Security Documents to perform its obligations hereunder or thereunder. None of the Collateral Agent or any of its respective Affiliates shall be under any obligation to the Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this or any other Indenture or the Security Documents or to inspect the properties, books, or records of any Issuer, any Guarantor or any of their Affiliates.

(c) The Collateral Agent and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory,

underwriting, or other business with the Issuers, any Guarantor and their Affiliates as though it was not the Collateral Agent hereunder and without notice to or consent of the Trustee. The Trustee and the Holders acknowledge that, pursuant to such activities, the Collateral Agent or its Affiliates may receive information regarding any Issuer, Guarantor or their respective Affiliates (including information that may be subject to confidentiality obligations in favor of, any such Issuer, any such Guarantor or such Affiliate) and acknowledge that the Collateral Agent shall not be under any obligation to provide such information to the Trustee or the Holders. Nothing herein shall impose or imply any obligation on the part of the Collateral Agent to advance funds.

(d) The Collateral Agent is authorized and directed to (i) enter into the Security Documents, (ii) bind the Holders on the terms as set forth in the Security Documents and (iii) perform and observe its obligations under the Security Documents.

(e) The Trustee agrees that it shall not (and shall not be obligated to), and shall not instruct the Collateral Agent to, unless specifically requested to do so by a majority of the Holders, take or cause to be taken any action to enforce its rights under this Indenture or against any Guarantor, including the commencement of any legal or equitable proceedings, to foreclose any Lien on, or otherwise enforce any security interest in, any of the Collateral.

If at any time or times the Trustee shall receive (i) by payment, foreclosure, set-off or otherwise, any proceeds of Collateral or any payments with respect to the Obligations arising under, or relating to, this Indenture, except for any such proceeds or payments received by the Trustee from the Collateral Agent pursuant to the terms of this Indenture, or (ii) payments from the Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article VI, the Trustee shall promptly turn the same over to the Collateral Agent, in kind, and with such endorsements as may be required to negotiate the same to the Collateral Agent.

(f) The Collateral Agent is each Holder’s agent for the purpose of perfecting the Holders’ security interest in assets which, in accordance with Article 9 of the Uniform Commercial Code (or other personal property security legislation) can be perfected only by possession. Should the Trustee obtain possession of any such Collateral, upon request from the Issuers, the Trustee shall notify the Collateral Agent thereof, and, promptly upon the Collateral Agent’s request therefor shall deliver such Collateral to the Collateral Agent or otherwise deal with such Collateral in accordance with the Collateral Agent’s instructions.

(g) The Collateral Agent shall have no obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by any Issuer, any Guarantor or is cared for, protected, or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all or the Issuer or any Guarantor’s property constituting collateral intended to be subject to the Lien and security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture or any Security Document, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Agent may act in any manner it may deem appropriate, in its sole discretion given the Collateral Agent’s own interest in the Collateral and that the Collateral Agent shall have no other duty or liability whatsoever to the Trustee or any Holder as to any of the foregoing.

(h) No provision of this Indenture or any Security Document shall require the Collateral Agent (or the Trustee) 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 in the case of the Collateral Agent) if it shall have reasonable grounds for believing that repayment of such funds is not assured to it. Notwithstanding anything to the contrary contained in this Indenture, the Intercreditor Agreement or the Security 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 to inspect or conduct any studies of any property under the mortgages 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 or indemnity from the Holders in an amount and in a form all 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) The Collateral Agent (i) shall not be liable for any action it takes or omits to take in good faith which it reasonably believes to be authorized or within its rights or powers, or for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Collateral Agent was grossly negligent in ascertaining the pertinent facts, (ii) shall not be liable for interest on any money received by it except as the Collateral Agent may agree in writing with the Issuers (and money held in trust by the Collateral Agent need not be segregated from other funds except to the extent required by law), (iii) the Collateral Agent may consult with counsel of its selection and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it in good faith and in accordance with the advice or opinion of such counsel. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act.

(j) Neither the Collateral Agent nor the Trustee shall be liable for delays or failures in performance resulting from acts beyond its control. Such acts shall include but not be limited to acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes or other disasters. Neither the Collateral Agent nor the Trustee shall be liable for any indirect, special or consequential damages (included but not limited to lost profits) whatsoever, even if it has been informed of the likelihood thereof and regardless of the form of action.

(k) The Collateral Agent may execute any of its duties under this Indenture and the Security Documents by or through agents, in particular, but not limited to, the Credit Agreement Collateral Agent (as defined in the Intercreditor Agreement) subject to the terms of the Intercreditor Agreement, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties.

(l) In each case that the Collateral Agent may or is required hereunder or under any other Notes Document 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 other Notes Document, the Collateral Agent may seek direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. The Collateral Agent shall not be liable with respect to any Action taken or omitted to be taken by it in accordance with the direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. If the Collateral Agent shall request direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes with respect to any Action, the Collateral Agent shall be entitled to refrain from such Action unless and until the Collateral Agent shall have received direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes, and the Collateral Agent shall not incur liability to any Person by reason of so refraining.

(m) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless a Trust Officer of the Collateral Agent shall have received written notice from the Trustee 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 Holders of a majority in aggregate principal amount of the Notes subject to this Section 12.3.

(n) To the extent not inconsistent, the Collateral Agent shall be entitled to all of the protections, immunities, indemnities, rights and privileges of the Trustee set forth in this Indenture.

(o) With respect to any Lien, including any Lien on Shared Collateral (as defined in the Intercreditor Agreement) created under a Security Document which is governed by Swiss law (“Swiss Liens”):

(i) the Collateral Agent or the Bailee Collateral Agent (as defined in the Intercreditor Agreement) (and each agent or sub-agent or attorney-in-fact appointed by the Collateral Agent or the Bailee Collateral Agent from time to time pursuant to the terms of the Intercreditor Agreement) shall accept, hold, administer and, as the case may be, enforce or release:

acting in its own name and as representative (direkter Stellvertreter) in the name and for account of each Holder and the Trustee;

(ii) the Collateral Agent or the Bailee Collateral Agent (and each agent or sub-agent or attorney-in-fact appointed by the Collateral Agent or the Bailee Collateral Agent from time to time pursuant to the terms of the Intercreditor Agreement) shall accept, hold, administer and, as the case may be, enforce or release:

as fiduciary (treuhänderisch) in its own name but for the benefit of itself, each Holder and the Trustee;

(iii) each present and future Holder and the Trustee hereby appoints, instructs and authorizes the Collateral Agent or the Bailee Collateral Agent (and each agent or sub-agent or attorney-in-fact appointed by the Collateral Agent or the Bailee Collateral Agent from time to time pursuant to the terms of the Intercreditor Agreement) to accept, hold, administer and, as the case may be, enforce or release the Swiss Liens, the benefit of sub-paragraphs (i) and (ii) and any proceeds of such Swiss Liens as set out in sub-paragraphs (i) and (ii) and in the respective Security Document constituting the Swiss Liens, and the Collateral Agent or the Bailee Collateral Agent (and each agent or sub-agent or attorney-in-fact appointed by the Collateral Agent or the Bailee Collateral Agent from time to time pursuant to the terms of the Intercreditor Agreement) hereby accepts such appointment;

(iv) each present and future Holder and the Trustee hereby instructs and authorizes the Collateral Agent or the Bailee Collateral Agent (and each agent or sub-agent or attorney-in-fact appointed by the Collateral Agent or the Bailee Collateral Agent from time to time pursuant to the terms of the Intercreditor Agreement) in its own name and/or in the name of such Holder or the Trustee as its representative (direkter Stellvertreter), as the case may be to give effect to this Section 12.2.(o), to enter into, amend, replace, rescind or terminate any Security Document or other document constituting the Swiss Liens, 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 Liens on behalf of such Holder or the Trustee; and

(v) this Section 12.2.(o) shall apply mutatis mutandis to all other provisions of this Notes Documents under which the Collateral Agent or the Bailee Collateral Agent (and each agent or sub-agent or attorney-in-fact appointed by the Collateral Agent or the Bailee Collateral Agent from time to time pursuant to the terms of the Intercreditor Agreement) and/or Trustee is instructed and authorized (i) to accept, hold, administer and, as the case may be, enforce or release the Swiss Liens and/or (ii) to enter into, amend, replace, rescind or terminate any Security Document or other document constituting the Swiss Liens and to exercise any rights and perform any obligations thereunder.

SECTION 12.3. Recordings and Opinions. The Issuers shall comply with the provisions of § 314(b) of the Trust Indenture Act following qualification of this Indenture pursuant to the Trust Indenture Act, except to the

extent not required as set forth in any SEC regulation or interpretation (including any no-action letter issued by the Staff of the SEC, whether issued to the Issuers or any other Person), subject to the requirements of the Trust Indenture Act. Following such qualification, to the extent the Issuers are required to furnish to the Trustee an Opinion of Counsel pursuant to Trust Indenture Act Section 314(b)(2), the Issuers shall furnish such opinion as required by such Section.

(a) Each Holder of Notes, by its acceptance thereof, consents and agrees to the terms of each Security Document and the Intercreditor Agreement, as originally in effect and as amended, restated, amended and restated, renewed, modified, supplemented or replaced from time to time in accordance with its terms or the terms of this Indenture, authorizes and directs the Trustee to authorize the Collateral Agent to enter into the Security Documents to which it is a party, authorizes and empowers the Trustee and the Collateral Agent to enter into the Intercreditor Agreement and any Future Intercreditor Agreement and authorizes and empowers the Trustee and the Collateral Agent to bind the Holders of Notes pursuant to the terms of the Intercreditor Agreement and any Future Intercreditor Agreement, make the representations of the Holders set forth therein and to perform their respective obligations and exercise their respective rights and powers under the Security Documents ; provided, however, that if any of the provisions of the Security Documents limit, qualify or conflict with the duties imposed by the provisions of the Trust Indenture Act, the Trust Indenture Act shall control.

(b) The Trustee is authorized and empowered to receive for the benefit of the Holders of Notes any funds collected or distributed under the Security Documents to which the Trustee is entitled pursuant to the terms of the Intercreditor Agreement and to make further distributions of such funds to the Holders of Notes according to the provisions of this Indenture.

(c) Subject to the Intercreditor Agreement, the Trustee is authorized and empowered to institute and maintain, or direct the Collateral Agent to institute and maintain, such suits and proceedings as it may deem expedient to protect or enforce the Liens of the Security Documents or to prevent any impairment of Collateral by any acts that may be unlawful or in violation of the Security Documents.

(a) Collateral may be released from the Lien and security interest created by the Security Documents to secure the Obligations at any time or from time to time as required by the terms of the Intercreditor Agreement or any Future Intercreditor Agreement and this Section 12.5. The applicable assets included in the Collateral shall be automatically released from the Liens securing the Notes Obligations under any one or more of the following circumstances:

(1) in part, in connection with any sale or other disposition of Collateral to a Person that is not a Restricted Subsidiary, an Issuer or a Guarantor (but excluding any transaction subject to Section 4.1), if such sale or other disposition does not violate the covenant described under Section 3.5 or is otherwise permitted in accordance with this Indenture;

(2) in part, in the case of a Guarantor that is released from its Note Guarantee pursuant to Section 10.2, the release of the Capital Stock, of such Guarantor;

In addition, the Liens on the Collateral securing the Notes and the Guarantees also will be released upon (i) payment in full of the principal of, together with accrued and unpaid interest on, the Notes and all other Notes Obligations that are due and payable at or prior to the time such principal, together with accrued and unpaid interest, is paid or (ii) a Legal Defeasance or Covenant Defeasance under Article VIII or a discharge in accordance with Article XI.

Upon the receipt of an Officer’s Certificate from the Issuers, as described in Section 12.5(b) below and any necessary or proper instruments of termination, satisfaction or release prepared by the Issuers, the Collateral Agent shall execute, deliver or acknowledge such instruments or releases to evidence the release of any Collateral permitted to be released pursuant to this Indenture, the Security Documents, the Intercreditor Agreement or any Future Intercreditor Agreement.

Each Holder authorizes the Collateral Agent and the Credit Agreement Collateral Agent (as defined in the Intercreditor Agreement) to release such Collateral at its discretion without notification or further reference to the Holders.

SECTION 12.6. Permitted Releases Not to Impair Lien; Trust Indenture Act Requirements.

(a) To the extent applicable, the Issuers shall cause § 313(b) of the Trust Indenture Act, relating to reports, and § 314(d) of the Trust Indenture Act, relating to the release of property or securities subject to the Lien of the Security Documents, to be complied with.

(b) Any release of Collateral permitted by Section 12.5 hereof shall be deemed not to impair the Liens under this Indenture and the Security Documents in contravention thereof and any Person that is required to deliver a certificate or opinion under this Indenture or any Collateral Document shall be entitled to rely upon the foregoing as a basis for delivery of such certificate or opinion. Any certificate or opinion required by § 314(d) of the Trust Indenture Act may be made by an officer or legal counsel, as applicable, of the Issuers except in cases where § 314(d) of the Trust Indenture Act requires that such certificate or opinion be made by an independent Person, which Person shall be an independent engineer, appraiser or other expert selected by or reasonably satisfactory to the Trustee.

(c) Notwithstanding anything to the contrary in this Section 12.6, the Issuers shall not be required to comply with all or any portion of § 314(d) of the Trust Indenture Act if it determines, in good faith based on the written advice of counsel, a copy of which written advice shall be provided to the Trustee, that under the terms of § 314(d) of the Trust Indenture Act or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of § 314(d) of the Trust Indenture Act is inapplicable to any release or series of releases of Collateral

SECTION 12.7. 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 XII 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 XII; and if the Trustee or the Collateral Agent shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee or the Collateral Agent, as the case may be.

SECTION 12.8. No Fiduciary Duties: Collateral. Neither the Trustee nor the Collateral Agent shall be deemed to owe any fiduciary duty to any holder of Pari Passu Secured Obligations and neither shall be liable to any such holder of Pari Passu Secured Obligations if the Trustee shall in good faith mistakenly pay over or distribute to Holders of Notes or to the Issuers or to any other person cash, property or securities to which any holder of Pari Passu Secured Obligations shall be entitled by virtue of this Article or otherwise. With respect to the holder of Pari Passu Secured Obligations, the Trustee and the Collateral Agent undertake to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article and the Intercreditor Agreement and no implied covenants or obligations with respect to the holder of Pari Passu Secured Obligations shall be read into this Indenture against the Trustee or the Collateral Agent.

In the event of any conflict or inconsistency between the terms of the Intercreditor Agreement or any Future Intercreditor Agreement and the terms of this Indenture, the terms of the Intercreditor Agreement or such Future Intercreditor Agreement shall govern.

SECTION 13.1. Trust Indenture Act Controls. If and to the extent that any provision of this Indenture limits, qualifies or conflicts with another provision which is required to be included in this Indenture by the TIA, the provision required by the TIA shall control. Each Guarantor in addition to performing its obligations under its Guarantee shall perform such other obligations as may be imposed upon it with respect to this Indenture under the TIA.

SECTION 13.2. Notices. Any notice, request, direction, consent or communication made pursuant to the provisions of this Indenture or the Notes shall be in writing and delivered in person, sent by facsimile, sent by electronic mail in PDF format, delivered by commercial courier service or mailed by first-class mail, postage prepaid, addressed as follows:

Notwithstanding any other provision of this Indenture or any Note, where this Indenture or any Note provides for notice of any event (including any notice of redemption or purchase) to a Holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given if given to DTC (or its designee) pursuant to the standing instructions from DTC or its designee.

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 13.6. 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 Trust 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 13.7. 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 13.8. 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 13.9. Governing Law. THIS INDENTURE, THE NOTES AND THE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. THE APPLICATION OF THE PROVISIONS SET OUT IN ARTICLES 86 TO 94-8 OF THE LUXEMBOURG LAW ON COMMERCIAL COMPANIES DATED AUGUST 10, 1915 IS EXCLUDED.

SECTION 13.10. Jurisdiction. 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 Guarantee or the Notes may be instituted in any state or Federal court in the Borough of Manhattan, New York, New York, and any appellate court from any thereof, and each of them irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding. 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 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 13.11. Waivers of Jury Trial. EACH OF THE ISSUERS, THE GUARANTORS AND THE TRUSTEE HEREBY 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 GUARANTEES AND FOR ANY COUNTERCLAIM THEREIN.

SECTION 13.12. 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 13.13. No Recourse Against Others. No director, officer, employee, incorporator or shareholder of the Issuers or any of their Subsidiaries or Affiliates, or 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 Guarantees, this Indenture or the Security Documents or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for 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 13.14. 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 in this Indenture shall bind its successors.

SECTION 13.15. 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 facsimile or PDF 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 by facsimile or PDF shall be deemed to be their original signatures for all purposes.

SECTION 13.16. Qualification of Indenture. The Issuers have agreed to qualify this Indenture under the TIA in accordance with the terms and conditions of the Registration Rights Agreement and to pay all reasonable costs and expenses (including attorneys’ fees and expenses for the Issuers, the Trustee and the Holders) incurred in connection therewith, including, but not limited to, costs and expenses of qualification of this Indenture and the Notes and printing this Indenture and the Notes. The Trustee shall be entitled to receive from the Issuers any such Officer’s Certificates, Opinions of Counsel or other documentation as it may reasonably request in connection with any such qualification of this Indenture under the TIA.

SECTION 13.17. 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 13.18. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, 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 13.19. 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 13.20. Jurisdiction. The Issuers consent to the exclusive jurisdiction of the United States District Court for the Southern District of New York and any appellate court from thereof. Each of the Issuers and the Guarantors appoint CT Corporation System, located at 111 Eighth Avenue, 13th Floor, New York, New York as its authorized agent upon which service of process may be served in any action or proceeding brought in the United States District Court for the Southern District of New York or any U.S. Federal court sitting in The City of New York in connection with either this Indenture or the Notes.

SECTION 13.21. Waiver of Immunities. To the extent that the Issuers may in any jurisdiction claim for itself or its 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 Trustee and the Holders not to claim, and irrevocably waive, the immunity to the full extent permitted by law.

SECTION 13.22. Currency Rate Indemnity. The Issuers agree that, if a judgment or order made by any court for the payment of any amount in respect of any Notes is expressed in a currency other than U.S. dollars, the Issuers will indemnify the Trustee and the relevant Holder against any deficiency arising from any variation in rates of exchange between the date as of which the U.S. dollars currency is notionally converted into the judgment currency for the purposes of the judgment or order and the date of actual payment. This indemnity constitutes a separate and independent obligation from the Issuers’ other obligations under this Indenture, gives rise to a separate and independent cause of action, applies irrespective of any indulgence granted from time to time and will continue in full force and effect notwithstanding any judgment or order for a liquidated sum or sums in respect of amounts due under this Indenture or the Notes.

SECTION 13.23. Interest Act (Canada). For purposes of the Interest Act (Canada), whenever any interest payable by the Issuers on the Notes is calculated using a rate based on a year of 360 days, such rate used pursuant to such calculation, when expressed as an annual rate, is equivalent to (x) the applicable rate based on a year of 360 days, (y) multiplied by the actual number of days in the calendar year in which the period for which such interest is payable (or compounded) ends, and (z) divided by 360. The principle of deemed reinvestment of interest does not apply to any interest calculation on the Notes with respect to the Issuers, and the rates of interest stipulated in this Notes payable by the Issuers are intended to be nominal rates and not effective rates or yields.

IN WITNESS WHEREOF, the parties have caused this Indenture to be duly executed all as of the date and year first written above.

Trinseo Materials Operating S.C.A., a company (société en commandite par actions) organized and existing under the laws of the Grand Duchy of Luxembourg and registered with the Luxembourg Trade and Companies Register under number B 153586, and Trinseo Materials Finance, Inc., a Delaware corporation (such companies, and their successors and assigns under the Indenture hereinafter referred to, being herein called the “Issuers”), promise to pay interest on the principal amount of this Note at 8.750% per annum from January 29, 2013 until maturity and shall pay Additional Interest, if any, payable pursuant to the Registration Rights Agreement referred to below. The Issuers will pay interest semi-annually in arrears every February 1 and August 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes 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 1, 2013. 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 (including Additional 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.

In addition to the rights provided to Holders of the Notes under the Indenture, Holders of Registrable Notes (as defined in the Registration Rights Agreement) shall have all rights set forth in the Registration Rights Agreement, dated as of January 29, 2013, among the Issuers, the Guarantors named therein and the other parties named on the signature pages thereto (the “Registration Rights Agreement”), including the right to receive Additional Interest in certain circumstances. If applicable, Additional Interest shall be paid to the same Persons, in the same manner and at the same times as regular interest.

By no later than 10:00 a.m. (New York City time) on the date on which any principal of, premium, if any, interest or Additional Interest, if any, 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, interest and Additional Interest when due. Interest on any Note which is payable, and is timely 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 preceding January 15 and July 15 at the office or agency of the Issuers maintained for such purpose pursuant to Section 2.3 of the Indenture. The principal of (and premium, if any) and interest (and Additional Interest, if any) on the Notes shall be payable at the office or agency of the Paying Agent or Registrar designated by the Issuers maintained for such purpose (which shall initially be the office of the Trustee maintained for such purpose), or at such other office or agency of the Issuers as may be maintained for such purpose pursuant to Section 2.3 of the Indenture; 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, interest and Additional Interest, if any) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depository. Payments in respect of Notes represented by Definitive Notes (including principal, premium, if any, interest and Additional Interest, if any) 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). If an Interest 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.

The Issuers initially appoint Wilmington Trust, National Association (the “Trustee”) as Registrar and Paying Agent for the Notes. The Issuers may change any Registrar or Paying Agent without prior notice to the Holders. Either Issuer or any Guarantor may act as Paying Agent, Registrar or transfer agent.

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

If money for the payment of principal, premium, if any, interest or Additional Interest, if any, 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.

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 U.S. dollars or U.S. Government Obligations for the payment of principal, premium, if any, interest and Additional Interest, if any on the Notes to redemption or maturity, as the case may be.

Subject to certain exceptions contained in the Indenture, the Indenture and the Notes may be amended, or a Default thereunder may be waived, with the consent of the Holders of a majority in aggregate principal amount of the outstanding Notes. Without notice to or the consent of any Holder, the Issuers, the Guarantors and the Trustee may amend or supplement the Indenture and the Notes as provided in the Indenture.

If an Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of an Issuer or certain Guarantors) occurs and is continuing, the Trustee by notice to the Issuers, or the Holders of at least 30% in principal amount of the outstanding Notes by notice to the Issuers and the Trustee, may declare the principal of, premium, if any, and accrued and unpaid interest (including Additional Interest, if any), and any other monetary obligations on all the Notes to be due and payable immediately. Upon the effectiveness of such declaration, such principal, premium, interest, Additional Interest, if any, 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 (including Additional 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.

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; provided, however, that if the Trustee acquires any conflicting interest under the TIA, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the Commission for permission to continue acting as Trustee or (iii) resign.

No 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 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.

This Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent acting on its behalf) manually signs the certificate of authentication on the other side of this Note.

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).

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.

The words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.

SECTION 2.1. Agreement to Be Bound. [Subject to Section 2.3, the] [The] Guaranteeing Subsidiary hereby becomes a party to the Indenture as a Guarantor and as such will have all of the rights and be subject to all of the obligations and agreements of a Guarantor under the Indenture.

SECTION 2.2. Guarantee. [Subject to Section 2.3, the] [The] Guaranteeing Subsidiary agrees, on a joint and several basis with all the existing Guarantors, to fully, unconditionally and irrevocably Guarantee to each Holder of the Notes and the Trustee the Guaranteed Obligations pursuant to Article X of the Indenture on a senior basis.

(a) To the extent that (i) the Guaranteeing Subsidiary becomes, under Article X of the Indenture or under any other provision of any Notes Document, the Registration Rights Agreement or the Purchase Agreement (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 Guaranteeing Subsidiary’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 Guaranteeing Subsidiary or would otherwise be restricted under Swiss corporate law then applicable (the “Restricted Obligations”), the aggregate liability of the Guaranteeing Subsidiary for Restricted Obligations shall be limited to the amount of unrestricted equity capital surplus (including the unrestricted portion of general and statutory reserves, other free reserves, retained earnings and current net profits) available for distribution as dividends to the shareholders of the Guaranteeing Subsidiary at the time the Guaranteeing Subsidiary 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 Guaranteeing Subsidiary 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.

(A) deduct Swiss Withholding Tax at the rate of 35 per cent. (or such other rate as in force from time to time) from any payment made by it in respect of Restricted Obligations;

(C) notify (and the Issuers shall ensure that the Guaranteeing Subsidiary will notify) the Trustee 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 or the Issuers under any Transaction Document to indemnify the Holders of the Notes and the Trustee in respect of the deduction of the Swiss Withholding Tax). The Guaranteeing Subsidiary 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 Guaranteeing Subsidiary under and pursuant to the relevant Transaction Document.

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

(4) revaluation of hidden reserves (if and to the extent permitted by mandatory Swiss law);

(5) approval by a shareholders’ meeting of the Guaranteeing Subsidiary of the (resulting) profit distribution; and

(6) all such other measures necessary or useful to allow the Guaranteeing Subsidiary to make the payments agreed hereunder with a minimum of limitations.

(d) Any Collateral granted by the Guaranteeing Subsidiary under any Security Document shall, by inclusion of respective language in such Security Document(s), also be made subject to the limitations set out in this Section 2.3.]³

(a) The restrictions in this Section 2.03 shall apply to any Guaranty and indemnity (the “German Guaranty”) granted by a Guarantor (a “German Guarantor”) incorporated under the laws of Germany as a limited liability company (“GmbH”) for liabilities of its direct or indirect shareholder(s) (upstream) or an entity affiliated with such shareholder (verbundenes Unternehmen) within the meaning of section 15 of the German Stock Corporation Act (Aktiengesetz) (cross-stream) (excluding, for clarification purposes any direct or indirect Subsidiary of such Guarantor).

(b) The restrictions in this Section 2.03 shall not apply to the extent the German Guarantor secures any indebtedness under the Notes to the extent they are on-lent or otherwise (directly or indirectly) passed on to the relevant German Guarantor or its Subsidiaries and such amount on-lent or otherwise passed on is not repaid for as long as such amounts on-lent or otherwise (directly or indirectly) passed on as set out above have not been the subject of an adjustment in the calculation of the relevant German Guarantor’s Net Assets in accordance with Section 2.03(d) below.

(i) The parties to this Guaranty agree that if payment under the German Guaranty would (A) cause the amount of a German Guarantor’s net assets, as calculated pursuant to Section 2.03 (d) below, to fall below the amount of its registered share capital (Stammkapital) or increase an existing shortage of its registered share capital in each case in violation of section 30 of the German Limited Liability Company Act (“GmbHG”) (such event is hereinafter referred to as a “Capital Impairment”) or (B) deprive the German Guarantor of the liquidity necessary to fulfill its financial liabilities to its creditors a (“Liquidity Impairment”), then the Trustee shall, subject to Section 2.03(c)(i) and (ii), demand payment under the German Guaranty from such German Guarantor only to the extent such Capital Impairment or Liquidity Impairment would not occur.

(ii) The restrictions set out in Section 2.03(c) in relation to a Liquidity Impairment shall cease to apply, if, at the time a demand for payment under the German Guaranty is made against a German Guarantor, such German Guarantor is unable to pay its debts as they fall due (zahlungsunfähig) or (ii) insolvency proceedings (Insolvenzverfahren) over any of such German Guarantor’s assets have been opened.

(iii) If the relevant German Guarantor does not notify the Trustee in writing (the “Management Notification”) within fifteen (15) Business Days after the Trustee notified such German Guarantor in writing of its intention to demand payment under the German Guaranty that a Capital Impairment or Liquidity Impairment would occur (setting out in reasonable detail to what extent a Capital Impairment or Liquidity Impairment would occur in the form of a management balance sheet (including explanations with regard to the Liquidity Impairment) and providing prima facie evidence that a realization or other measures undertaken in accordance with the mitigation provisions set out in Section 2.03(e) would not prevent such Capital Impairment and/or Liquidity Impairment), then the restrictions set forth in clause (i) of this Section 2.03(c) shall not apply.

(iv) If the relevant German Guarantor does not provide an Auditors’ Determination (as defined in Section 2.03(f)) within thirty (30) Business Days from the date on which the Trustee received the Management Notification, then the restrictions set out in clause (i) of this Section 2.03(c) shall not apply and the Trustee shall not be obliged to assign or make available to the German Guarantor any net proceeds realized.

(d) Net Assets. The calculation of net assets (the “Net Assets”) shall only take into account the sum of the values of the assets of the relevant German Guarantor determined in accordance with applicable law and court decisions and, if there is no positive going concern (positive Fortführungsprognose) based on the lower of book value (Buchwert) and liquidation value (Liquidationswert) (consisting of all assets which correspond to those items listed in section 266 subsection (2) A, B and C of the German Commercial Code (“HGB”)) less the relevant German Guarantor’s liabilities (consisting of all liabilities and liability reserves which correspond to those items listed in accordance with section 266 subsection (3) B, C and D of the HGB). For the purposes of calculating the Net Assets, the following balance sheet items shall be adjusted as follows:

(i) the amount of any increase in the registered share capital of the relevant German Guarantor which was carried out after the relevant German Guarantor became a party to this Guaranty without the prior written consent of the Trustee shall be deducted from the amount of the registered share capital of the relevant German Guarantor;

(ii) any funds received by any Issuer under the issuance of the Notes which have been or are on-lent or otherwise passed on to the relevant German Guarantor or to any Subsidiary of such German Guarantor and have not yet been repaid at the time when payment under the German Guaranty is demanded, shall be disregarded for as long as no demand has been made in relation to such amounts on-lent or otherwise (directly or indirectly) passed on as set out above under the Guarantee by the relevant German Guarantor in accordance with Section 2.03(b) above; and

(iii) loans or other contractual liabilities incurred by the relevant German Guarantor in gross-negligent or willful breach of Notes Documents or the shall not be taken into account as liabilities.

(i) The relevant German Guarantor shall realize, to the extent legally permitted and commercially justifiable in a situation where it does not have sufficient Net Assets to maintain its registered share capital, all of its assets that are shown in the balance sheet with a book value (Buchwert) that is significantly lower than the market value of the assets but only if the relevant asset is not necessary for the German Guarantor’s business (betriebsnotwendig).

(ii) The limitations on demanding payment under this German Guaranty set out in this Section 2.03(e) shall not apply if and to the extent that the relevant German Guarantor is legally permitted to

dissolve hidden reserves or setting-off claims to avoid demanding payment under the German Guaranty causing a Capital Impairment of the relevant German Guarantor provided that it is commercially justifiable to take such measures.

(i) If the relevant German Guarantor claims that a Capital Impairment or Liquidity Impairment would occur on payment under this German Guaranty and the Trustee has requested an Auditors’ Determination (as defined below), the German Guarantor shall (at its own cost and expense) arrange for the preparation of a balance sheet by a firm of recognized auditors (the “Auditors”) in order to have such Auditors determine whether (and if so, to what extent) any payment under this German Guaranty would cause a Capital Impairment or Liquidity Impairment (the “Auditors’ Determination”).

(ii) The Auditors’ Determination shall be prepared, taking into account the adjustments set out in Section 2.03(d) above, by applying the generally accepted accounting principles applicable from time to time in Germany (Grundsätze ordnungsmäßiger Buchführung) based on the same principles and evaluation methods as constantly applied by the relevant German Guarantor in the preparation of its financial statements, in particular in the preparation of its most recent annual balance sheet, and taking into consideration applicable court rulings of German courts. Subject to SECTION 2.03 (h) below, such Auditors’ Determination shall be binding on the relevant German Guarantor and the Trustee.

(iii) Even if the relevant German Guarantor arranges for the preparation of an Auditors’ Determination, the relevant German Guarantor’s obligations under the mitigation provisions set out in Section 2.03(e) above shall continue to exist.

(g) Improvement of Financial Condition. If, after it has been provided with an Auditors’ Determination which prevented it from demanding any or only partial payment under this German Guaranty, the Trustee ascertains in good faith that the financial condition of the relevant German Guarantor as set out in the Auditors’ Determination has substantially improved (in particular, if the relevant German Guarantor has taken any action in accordance with the mitigation provisions set out in Section 2.03(e)), the Trustee may, at the relevant German Guarantor’s cost and expense, arrange for the preparation of an updated balance sheet of the relevant German Guarantor by applying the same principles (unless a change of law or court practice requires otherwise) that were used for the preparation of the Auditors’ Determination by the Auditors who prepared the Auditors’ Determination pursuant to clause (i) of Section 2.03(f) above in order for such Auditors to determine whether (and, if so, to what extent) the Capital Impairment or Liquidity Impairment has been cured as a result of the improvement of the financial condition of the relevant German Guarantor. The Trustee may demand payment under this German Guaranty to the extent that the Auditors determine that the Capital Impairment or Liquidity Impairment has been cured.

(h) No Waiver. Nothing in this Section 2.03 shall limit the enforceability, legality or validity of this German Guaranty nor shall it prevent the Trustee from claiming in court that the provision of this German Guaranty by and/or demanding payment under this German Guaranty against the relevant German Guarantor does not fall within the scope of section 30 of the GmbHG. The Trustee’s rights to any remedies it may have against the relevant German Guarantor shall not be limited if it is ascertained by a final court decision that section 30 of the GmbHG did not apply. The agreement of the Trustee to abstain from demanding any or part of the payment under this German Guaranty in accordance with the provisions above shall not constitute a waiver (Verzicht) of any right granted under this Indenture or any other Notes Document to the Trustee, the Collateral Agent or any Secured Party.]⁴

(a) Each Guarantor which is party to any Security Document governed by Dutch law (the “Dutch Guarantors”) hereby irrevocably and unconditionally undertakes to pay to the Collateral Agent as creditor in its own right and not as a representative of the other Secured Parties amounts equal to any amounts owing from time to time by that Guarantor to any Secured Party under any Notes Document as and when those amounts are due for payment under the relevant Notes Document.

(b) Each Dutch Guarantor and the Collateral Agent acknowledge that the obligations of each Dutch Guarantor under Section 2.3(a) are several and are separate and independent from, and shall not in any way limit or affect, the corresponding obligations of that Dutch Guarantor to any Secured Party under any Notes Document (its “Corresponding Debt”) nor shall the amounts for which each Dutch Guarantor is liable under Section 2.3(a)) (its “Parallel Debt”) be limited or affected in any way by its Corresponding Debt provided that: (i) the Parallel Debt of each Dutch Guarantor shall be decreased to the extent that its Corresponding Debt has been irrevocably paid or (in the case of guarantee obligations) discharged and (ii) the Corresponding Debt of each Dutch Guarantor shall be decreased to the extent that its Parallel Debt has been irrevocably paid or (in the case of guarantee obligations) discharged.

(c) The Collateral Agent acts in its own name and not as a trustee, and its claims in respect of the Parallel Debt shall not be held on trust. The Security Documents governed by Dutch law granted under the Senior Secured Notes Documents to the Collateral Agent to secure the Parallel Debt is granted to the Collateral Agent in its capacity as creditor of the Parallel Debt and shall not be held on trust.

(d) All monies received or recovered by the Collateral Agent pursuant to this Section 2.3, and all amounts received or recovered by the Notes Documents from or by the enforcement of any Security Documents governed by Dutch law granted to secure the Parallel Debt, shall be applied in accordance with this Agreement.

(e) Without limiting or affecting the Collateral Agent’s rights against the Dutch Guarantors (whether under this Section 2.3 or under any other provision of the Notes Documents), each Dutch Guarantor acknowledges that: (i) nothing in this Section 2.3 shall impose any obligation on the Collateral Agent to advance any sum to any Dutch Guarantor or otherwise under any Notes Document, except in its capacity as lender (as applicable) and (ii) for the purpose of any vote taken under any Notes Document, the Collateral Agent shall not be regarded as having any participation or commitment other than those which it has in its capacity as a lender (as applicable).]⁵

[SECTION 2.3 Limitation for Swedish Guarantors. The obligations of any Guarantor incorporated in Sweden in its capacity as a Guarantor (each a “Swedish Guarantor”) shall be limited if (and only if) and to the extent required by an application of the provision of the Swedish Companies Act (Sw. Aktiebolagslagen (2005:551)) (or its equivalent from time to time) regulating distribution of assets (including profits and dividends and any other form of transfer or value) (Chapter 17, Section 1-3 (or its equivalent from time to time)) and it is understood that the liability of each Swedish Guarantor under this Indenture only applies to the extent permitted by the above mentioned provisions of the Swedish Companies Act, provided that all steps available to the Swedish Guarantors and their respective shareholder to authorize their obligations under the Indenture have been taken.]⁶

(a) The guarantee in this Article II does not apply to any liability of any Belgian Guarantor to the extent that such liability would result in the guarantee constituting unlawful financial assistance within the meaning of the Belgian Company Code. A “Belgian Guarantor” for the purposes of this Article II shall be any Guarantor with its main establishment (“voornaamste vestiging/établissement principal”) in Belgium.

(b) Further, the obligations of any Belgian Guarantor under the guarantee in this Article [ ] shall in all events be limited to a maximum aggregate amount equal to the greater of:

(A) the Net Assets (as defined below) of the Belgian Guarantor calculated on the basis of the last financial statements available on the date hereof;

(B) the Net Assets (as defined below) of the Belgian Guarantor calculated on the basis of the last audited financial statements or audited interim financial statements available on the date of the demand for payment by the Belgian Guarantor under the guarantee in this Article II; and

(C) the arithmetic mean of the Net Assets (as defined below) of such Belgian Guarantor on the basis of the last five audited financial statements of such Belgian Guarantor at the date a demand for payment is made under the guarantee in this Article II.

minus the amount paid or payable by such Belgian Guarantor pursuant to its guarantee obligations under the Credit Agreement.

For the purpose of this Article II, “Net Assets” means the aggregate amount of the assets of the Belgian Guarantor as shown in the audited financial statements referred to above:

(i) less the aggregate amount of all financial indebtedness (schulden/dettes) referred to in Article 320 or 617 of the Belgian Company Code, owed by the Belgian Guarantor;

(ii) less the aggregate amount of the provisions (voorzieningen/provisions) referred to in Article 320 or 617 of the Belgian Company Code;

(iii) plus the aggregate amount of all financial indebtedness (schulden/dettes) referred to in Article 320 or 617 of the Belgian Company Code that are owed by the Belgian Guarantor to another member of the Group as a result of any on-lending by that member to the Belgian Guarantor of proceeds drawn under this Agreement,

(2) the aggregate amount (plus any accrued interest thereon, expenses and fees) of:

(A) the amounts received by the Belgian Guarantor and by any Subsidiary of the Belgian Guarantor under [this Agreement], outstanding at any given time until the demand for payment by the Belgian Guarantor under this Agreement; and

(B) any intra-group loans or facilities made available to the Belgian Guarantor and to any Subsidiary of the Belgian Guarantor by any other member of the Group using directly or indirectly all or part of the proceeds made available pursuant to this Agreement.]⁷

[SECTION 2.3 Limitation for Irish Guarantors. The Guarantee does not apply to any liability to the extent that it would result in the Guarantee constituting unlawful financial assistance within the meaning of, in respect of a Guarantor incorporated under the laws of Ireland, section 60 of the Companies Act 1963 of Ireland.]⁸
