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

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

The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of the Paying Agent designated by the Company 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 Company as may be maintained for such purpose pursuant to Section  2.3 ; provided , however , that, at the option of the Paying Agent, each installment of interest may be paid by (i) check mailed to the addresses of the Persons entitled thereto as such addresses appear in the Notes Register or (ii) wire transfer to an account located in the United States maintained by the payee, subject to the last sentence of this paragraph. Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by DTC. Payments in respect of Notes represented by Definitive Notes (including principal, premium, if any, and interest) held by a Holder of at least $1,000,000 aggregate principal amount of Notes represented by Definitive Notes will be made in accordance with the Notes Register, or by wire transfer to a Dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

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

59

(c)     Denominations . The Notes shall be issuable only in fully registered form in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

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

THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT PURSUANT TO REGULATION S, AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ANY OTHER APPLICABLE JURISDICTION. TERMS USED IN THIS PARAGRAPH HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT.

(3)    Each Global Note, whether or not an Initial Note, shall bear a legend substantially in the form of the following on the face thereof:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“ DTC ”), NEW YORK, NEW YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO DTC, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.

(4)    The form of letter referred to in clause (D) of the second sentence in the legend set forth in clause (1) of this Section 2.1(d) shall be substantially in the form set forth in Exhibit C to this Indenture or such other form as the Company may from time to time provide to the Trustee.

61

(e)     Book-Entry Provisions . (i) This Section  2.1(e) shall apply only to Global Notes deposited with the Trustee, as Notes Custodian, and for which the applicable procedures of DTC shall govern.

(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 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 DTC, its successors or its respective nominees, except as set forth in Section  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 Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by 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 Company 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 Company 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.

62

(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 Company 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 Company within 90 days of such notice, (B) the Company in its sole discretion executes 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 clause (A), (B) or (C) of the preceding sentence, the Company shall promptly make available to the Registrar 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 Company 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 Company or any affiliate of the Company 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 Company 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.

63

(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 Company 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 Company 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.

(g)    Each purchaser or transferee by its purchase or acquisition of the Notes, shall be deemed to have represented and covenanted that either (a) no portion of the assets used to acquire and hold the Notes (or any interest therein) constitutes assets of any employee benefit plan subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ ERISA ”), any plan, individual retirement account (an “ IRA ”) or other arrangement that is subject to Section 4975 of the Code, or provisions under any other federal, state, local, non-U.S. or other laws, rules or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”) or an entity whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement under ERISA or the Code, including under U.S. Department of Labor regulation §2510.3-101, as modified by Section 3(42) of ERISA or under Similar Laws or (b) the acquisition and holding of the Notes (or any interest therein) will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation under any applicable Similar Law.

SECTION 2.2     Execution and Authentication . One Officer shall sign the Notes for the Company by manual or facsimile 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 signatory 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 $350,000,000, (2) subject to the terms of this Indenture, Additional Notes for original issue in an unlimited principal amount and (3) under the circumstances set forth in Section  2.6(e) , Initial Notes in the form of an Unrestricted Global Note, in each case upon a written order of the Company signed by one Officer (the “ Company Order ”). Such Company Order shall specify whether the Notes will be in the form of Definitive Notes or Global Notes, the amount of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated, the Holder of the Notes and whether the Notes are to be Initial Notes or Additional Notes.

64

The Trustee may appoint an agent (the “ Authenticating Agent ”) reasonably acceptable to the Company 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 Company. 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 the Company or any Guarantor, pursuant to Article IV or Section  10.2 , as applicable, shall consolidate with or merge with or into, or convey, transfer, lease or otherwise dispose of all or substantially all its assets, to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into which the Company 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 Company 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 Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “ Registrar ”) and an office or agency where Notes may be presented for payment. The Registrar shall keep a register of the Notes and of their transfer and exchange (the “ Notes Register ”). The Company 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 Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee in writing of the name and address of each such agent. If the Company fails 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 . The Company or any Guarantor may act as Paying Agent, Registrar or transfer agent.

65

The Company initially appoints DTC to act as Depositary with respect to the Global Notes. The Company initially appoints the Trustee as Registrar and Paying Agent for the Notes. The Company 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 Company 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 Company and the Trustee.

SECTION 2.4     Paying Agent to Hold Money in Trust . By no later than 11:00 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 Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium or interest when due. The Company 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 Company or other obligors on the Notes), shall notify the Trustee in writing of any default by the Company or any Guarantor in making any such payment and shall during the continuance of any default by the Company (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 the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent (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 Company 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 Company, 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. If the Trustee is not the Registrar, the Company, on its 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.

SECTION 2.6     Transfer and Exchange .

(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 Registrar a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion

66

or other document required by this Section  2.6 . The Registrar will promptly register any transfer or exchange that meets the requirements of this Section  2.6 by noting the same in the Notes Register maintained by the Registrar for the purpose, and no transfer or exchange will be effective until it is registered in such Notes Register. The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section  2.6 and Section  2.1(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 Registrar shall refuse to register any requested transfer or exchange that does not comply with this paragraph.

(b)     Transfers of Rule 144A Notes . The following provisions shall apply with respect to any proposed transfer of a Rule 144A Note:

(1)    A Rule 144A Note or beneficial interest therein may be transferred to a Non-U.S. Person who takes delivery in the form of a Regulation S Note or beneficial interest therein only if the transferor first delivers to the Registrar or its agent a certificate substantially in the form set forth in Section  2.9 hereof, to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S (if applicable).

(2)    A transfer of a Rule 144A Note or a beneficial interest therein to any Person may be made only if the transferor of the beneficial interest in the Rule 144A Note first delivers to the Registrar or its agent a certificate substantially in the form of assignment on the reverse of the Notes.

(c)     Transfers of Regulation S Notes . The following provisions shall apply with respect to any proposed transfer of a Regulation S Note:

(2)    A transfer of a Regulation S Note or a beneficial interest therein to a Non-U.S. Person shall be made only if the transferor first delivers to the Registrar or its agent (1) a certificate substantially in the form set forth in Section  2.9 hereof, to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S (if applicable) and (2) a certificate substantially in the form of assignment on the reverse of the Notes.

(3)    A transfer of a Regulation S Note or a beneficial interest therein to any other Person may be made only if the transferor of the beneficial interest in the Regulation S Note first delivers to the Registrar or its agent a certificate, substantially in the form of assignment on the reverse of the Notes.

67

(d)     Restricted Notes Legend . Upon the transfer, exchange or replacement of Notes not bearing a Restricted Notes Legend, the Registrar shall deliver Notes that do not bear a Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing a Restricted Notes Legend, the Registrar shall deliver only Notes that bear a Restricted Notes Legend unless (1) an Initial Note is being transferred pursuant to an effective registration statement, (2) Initial Notes are being exchanged for Notes that do not bear the Restricted Notes Legend in accordance with Section  2.6(e) or (3) there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Company to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. 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 Company’s 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 Company’s satisfaction that the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities Act, the Company 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 Company shall have previously otherwise made eligible for exchange with DTC, (ii) provide prior written notice (the “ Automatic Exchange Notice ”) to each Holder at such Holder’s address appearing in the register of Holders at least fifteen (15) calendar days prior to the Automatic Exchange Date (the “ Automatic Exchange Notice Date ”), which notice must include (w) the Automatic Exchange Date, (x) the section of this Indenture pursuant to which the Automatic Exchange shall occur, (y) the “CUSIP” number of the Restricted Global Note from which such Holder’s beneficial interests will be transferred and (z) the “CUSIP” number of the Unrestricted Global Note into which such Holder’s beneficial interests will be transferred, and (iii) on or prior to the Automatic Exchange Date, deliver to the Trustee for authentication one or more Unrestricted Global Notes, duly executed by the Company and a Company Order requesting the Trustee to authenticate, in an aggregate principal amount equal to the aggregate principal amount of Restricted Global Notes to be exchanged into such Unrestricted Global Notes.

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 Company. As a condition to any Automatic Exchange, the Company shall provide, and the

68

Trustee shall be entitled to conclusively rely upon, an Officer’s Certificate and Opinion of Counsel to the Company 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 cancelled 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 Company 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 Company 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 Company’s and Registrar’s written request.

No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company 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 Company (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 sending of a notice of an offer to repurchase or notice of redemption of Notes and ending at the close of business on the day of such sending 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 Company, the Trustee, the Paying Agent or the Registrar may deem and treat the person in whose name a Note is registered as the owner of such Note for the purpose of receiving payment of principal of, premium, if any, and (subject to paragraph 2 of the form of Notes attached hereto as Exhibit A ) interest on such Note and for all other purposes whatsoever, including without limitation the transfer or exchange of such Note, whether or not such Note is overdue, and none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

69

SECTION 2.10     [Reserved] .

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 destroyed, lost or stolen, the Company shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Company and the Trustee that such Note has been destroyed, lost or stolen within a reasonable time after such Holder has notice of such loss, destruction or stealing and the Registrar has not registered a transfer prior to receiving such notification, (b) makes such request to the Company 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 ”), (c) satisfies any other reasonable requirements of the Trustee and (d) provides an indemnity bond, as more fully described below; 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 Company 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 Company or the Trustee in connection therewith. Such Holder shall furnish an indemnity bond sufficient in the judgment of (i) the Trustee to protect the Trustee and (ii) the Company to protect the Company, the Trustee, the Paying Agent and the Registrar, from any loss which any of them may suffer if a Note is replaced, and, in the absence of notice to the Company, any Guarantor or the Trustee that such Note has been acquired by a protected purchaser, the Company shall execute, and upon receipt of a Company 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 Company in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section  2.11 , the Company 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 Company, 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.

72

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 cancelled by it, those delivered to it for cancellation, those paid pursuant to Section  2.11 and those described in this Section  2.12 as not outstanding. A Note does not cease to be outstanding in the event the Company or an Affiliate of the Company holds the Note; provided , however , that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, the provisions of Section  12.4 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 the Company or an Affiliate of the Company 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 Company 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 Company 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 Company considers appropriate for temporary Notes. Without unreasonable delay, the Company 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 Company 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 Company shall execute, and the Trustee shall, upon receipt of a Company 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.

73

SECTION 2.14     Cancellation . The Company may, at any time, 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 Company or any Guarantor acquires 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 Company may not issue new Notes to replace Notes it has paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

If the Company delivers a Global Note to the Trustee for cancellation on a date that is after a record date and on or before the corresponding interest payment date, then interest shall be paid to Holders in accordance with the applicable procedures of DTC.

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 Company 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 Company, at its election, as provided in clause (a) or (b) below:

(a)    The Company 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 Company 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 Company 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

74

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 Company 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 Company shall promptly notify the Trustee in writing of such Special Record Date, and in the name and at the expense of the Company, 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  12.1 , not less than 10 calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the provisions in Section  2.15(b) .

(b)    The Company 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 Company 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 interest, which were carried by such other Note.

SECTION 2.16     CUSIP and ISIN Numbers .

The Company 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 Company shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers.

(10)    in the event that the Company or a Restricted Subsidiary (x) incurs Indebtedness to finance an acquisition or (y) assumes Indebtedness of Persons that are acquired by the Company or any Restricted Subsidiary or merged into the Company or a Restricted Subsidiary in accordance with the terms of this Indenture, the date of determination of the Fixed Charge Coverage Ratio, the Consolidated Secured Leverage Ratio or the Consolidated Total Leverage Ratio, as applicable, shall, at the option of the Company, be the date that a definitive agreement for such acquisition is entered into and the Fixed Charge Coverage Ratio, the Consolidated Secured Leverage Ratio or the Consolidated Total Leverage Ratio, as applicable, shall be calculated giving pro forma effect to such acquisition and the other transactions to be entered into in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof) consistent with the definition of Fixed Charge Coverage Ratio, Consolidated Secured Leverage Ratio or Consolidated Total Leverage Ratio, as applicable, and, for the avoidance of doubt, (A) if any such ratios are exceeded as a result of fluctuations in such ratio (including due to fluctuations in the Consolidated EBITDA of the Company or the target company) at or prior to the consummation of the relevant acquisition, such ratios

81

will not be deemed to have been exceeded as a result of such fluctuations solely for purposes of determining whether such acquisition and any related transactions are permitted hereunder and (B) such ratios shall not be tested at the time of consummation of such acquisition or related transactions; provided, further , that if the Company elects to have such determinations occur at the time of entry into such definitive agreement, (i) any such transaction shall be deemed to have occurred on the date the definitive agreement is entered into and to be outstanding thereafter for purposes of calculating any ratios under this Indenture after the date of such agreement and before the earlier of the date of consummation of such acquisition or the date such agreement is terminated or expires without consummation of such acquisition and (ii) to the extent any covenant baskets were utilized in satisfying any covenants, such baskets shall be deemed utilized until the earlier of the date of consummation of such acquisition or the date such agreement is terminated or expires without consummation of such acquisition, but any calculation of Consolidated EBITDA for purposes of other incurrences of Indebtedness or Liens or making of Restricted Payments (not related to such acquisition) shall not reflect such acquisition until it has been consummated;

(11)    notwithstanding anything in this covenant to the contrary, in the case of any Indebtedness incurred to refinance Indebtedness initially incurred in reliance on a clause of Section  3.2(b) measured by reference to a percentage of LTM EBITDA or Total Assets at the time of Incurrence, if such refinancing would cause the percentage of LTM EBITDA or Total Assets restriction to be exceeded if calculated based on the percentage of LTM EBITDA or Total Assets on the date of such refinancing, such percentage of LTM EBITDA or Total Assets restriction shall not be deemed to be exceeded so long as the principal amount of such refinancing Indebtedness does not exceed (a) the principal amount of such Indebtedness being refinanced, plus (b) the Additional Refinancing Amount; and

(12)    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 .

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 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 ).

For purposes of determining compliance with any Dollar-denominated restriction on the Incurrence of Indebtedness, the Dollar equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect

82

on the date such Indebtedness was Incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided , that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable Dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such Dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed (a) the principal amount of such Indebtedness being refinanced plus (b) the Additional Refinancing Amount.

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 shall not, and shall not permit any Guarantor to, directly or indirectly, Incur any Indebtedness (including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of the Company 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 Note Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Company or such Guarantor, as the case may be. 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) unsubordinated Indebtedness shall not be treated as subordinated or junior to any other unsubordinated Indebtedness merely because it has a junior priority with respect to the same collateral or is secured by different collateral or because it is guaranteed by different obligors.

(3)    an amount equal to 100.0% of the Net Available Cash from such Asset Disposition is applied:

(i)    to the extent the Company or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of any Indebtedness), (A) to redeem, prepay, repay or purchase any Indebtedness of a non-Guarantor or any Secured Indebtedness (in each case, other than Indebtedness owed to the Company or any Restricted Subsidiary), including Indebtedness under the Credit Agreement (or any Refinancing Indebtedness in respect thereof) within 450 days from the later of (a) the date of such Asset Disposition and (b) the receipt of such Net Available Cash; provided , however , that, in connection with any redemption, 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 redeem, prepay, repay or purchase Pari Passu Indebtedness; provided further that, to the extent the Company redeems, repays or repurchases Pari Passu Indebtedness pursuant to this clause (B), the Company 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 100.0% 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 100.0% 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; and

(ii)    to the extent the Company or any 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 equal to the amount of Net Available Cash received by the Company or another Restricted Subsidiary) within 450 days from the later of (A) the date of such Asset Disposition and (B) the receipt of such Net Available Cash; provided , however , that a binding

93

agreement shall be treated as a permitted application of Net Available Cash from the date of such commitment with the good faith expectation that an amount equal to Net Available Cash will be applied to satisfy such commitment within 180 days of such commitment (an “ Acceptable Commitment ”) and, in the event of any Acceptable Commitment is later cancelled or terminated for any reason before such amount is applied in connection therewith, the Company or such Restricted Subsidiary enters into another Acceptable Commitment (a “ Second Commitment ”) within 180 days of such cancellation or termination; provided further that if any Second Commitment is later cancelled or terminated for any reason before such amount is applied, then such Net Available Cash shall constitute Excess Proceeds;

provided that, pending the final application of the amount 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)    The amount of any Net Available Cash from Asset Dispositions that is not applied or invested or committed to be applied or invested as provided in the preceding paragraph (it being understood that any portion of such Net Available Cash used to make an offer to repurchase Notes, as described in Section  3.5(a)(3) above, shall be deemed to have been so applied whether or not such offer is accepted) will be deemed to constitute “ Excess Proceeds ” under this Indenture. On the 451st day after the later of an Asset Disposition or the receipt of such Net Available Cash, 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 Indebtedness, to purchase the maximum principal amount of Notes and any such Pari Passu Indebtedness 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 100.0% of the principal amount of the Notes and Pari Passu Indebtedness, in each case, plus accrued and unpaid interest, if any, to, but not including, the date of purchase (or, in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness), 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 Company will deliver notice of such Asset Disposition Offer electronically or by first-class mail, with a copy to the Trustee, the Paying Agent and each Holder of Notes at the address of such Holder appearing in the security register or otherwise in accordance with the applicable 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 15 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. The Company may satisfy the foregoing obligations with respect to any Net Available Cash from an Asset Disposition by making an Asset Disposition Offer with respect to all Net Available Cash prior to the expiration of the relevant 450 days (or such longer period provided above) or with respect to any unapplied Excess Proceeds.

94

(c)    To the extent that the aggregate amount of Notes and Pari Passu Indebtedness 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 Indebtedness surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Company shall allocate the Excess Proceeds among the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Notes and Pari Passu Indebtedness, provided that no Notes or other Pari Passu Indebtedness will be selected and purchased in an unauthorized denomination. Upon completion of any Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero. Additionally, the Company may, at its option, make an Asset Disposition Offer using proceeds from any Asset Disposition at any time after the consummation of such Asset Disposition. Upon consummation or expiration of any Asset Disposition Offer, any remaining Net Available Cash shall not be deemed Excess Proceeds and the Company may use such Net Available Cash for any purpose not prohibited by this Indenture. To the extent that any portion of Net Available Cash payable in respect of the Notes is denominated in a currency other than Dollars, the amount thereof payable in respect of the Notes shall not exceed the net amount of funds in Dollars that is actually received by the Company upon converting such portion into Dollars.

(d)    Notwithstanding any other provisions of this Section  3.5 ,

(i)    to the extent that any of or all the Net Available Cash of any Asset Disposition by a Foreign Subsidiary (a “ Foreign Disposition ”) is (x) prohibited or delayed by applicable local law, (y) restricted by applicable organizational documents or any agreement or (z) subject to other onerous organizational or administrative impediments from being repatriated to the United States, the portion of such Net Available Cash so affected will not be required to be applied in compliance with this covenant, and such amounts may be retained by the applicable Foreign Subsidiary so long, but only so long, as the applicable local law, documents or agreements prohibit, delay, restrict or impede, as applicable, repatriation to the United States (the Company hereby agreeing to use reasonable efforts (as determined in the Company’s reasonable business judgment) to otherwise cause the applicable Foreign Subsidiary to, within one year following the date on which the respective payment would otherwise have been required, promptly take all actions reasonably required by the applicable local law, applicable organizational impediments or other impediment to permit such repatriation), and if within one year following the date on which the respective payment would otherwise have been required such repatriation of any of such affected Net Available Cash is not prohibited, delayed, restricted or impeded, as applicable, under the applicable local law, applicable organizational impediment or other impediment, such repatriated Net Available Cash will be promptly (and in any event not later than five (5) Business Days after such repatriation could be made) applied (net of additional Taxes payable or reserved against as a result thereof) (whether or not such repatriation actually occurs) in compliance with this Section  3.5 ; and

95

(ii)    to the extent that the Company has determined in good faith that repatriation of any of or all the Net Available Cash of any Foreign Disposition would have an adverse Tax consequence (which for the avoidance of doubt, includes, but is not limited to, any prepayment whereby doing so the Company, any Subsidiary, or any of their respective Affiliates and/or equity owners would incur a tax liability, including a taxable dividend, as a result of an income inclusion pursuant to Code Section 956 or any withholding tax), the Net Available Cash so affected will not be required to be applied in accordance with this Section  3.5 . The non-application of any prepayment amounts as a consequence of the foregoing provisions will not, for the avoidance of doubt, constitute a Default or an Event of Default.

(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 of the Company or 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, or the cancellation or termination of any such Indebtedness or liability in connection therewith;

(2)    securities, notes or other obligations received by the Company or any Restricted Subsidiary 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) 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 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 $20.0 million and 2.0% 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 provisions of this Indenture relating to the Company’s obligation to make an offer to repurchase the Notes as a result of an Asset Disposition may be waived or modified with the written consent of the Holders of a majority in principal amount of the then outstanding Notes.

96

(g)    To the extent that the provisions of any securities laws, rules or regulations, including Rule 14e-1 under the Exchange Act, conflict with the provisions of this Indenture, the Company will comply with the applicable securities laws, rules and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

SECTION 3.6     Limitation on Liens . The Company shall not, and shall not permit any Guarantor to, directly or indirectly, create, Incur or permit to exist any Lien (except Permitted Liens) (each, an “ Initial Lien ”) that secures obligations under any Indebtedness of the Company or any Guarantor, on any asset or property of the Company or any Guarantor, unless:

(1)    in the case of Liens securing Subordinated Indebtedness, the Notes and Note Guarantees are secured by a Lien on such property or assets that is senior in priority to such Liens; or

(2)    in all other cases, the Notes or the Note Guarantees are ratably secured with (or, at the Company’s election, secured on a senior basis to) the obligations so secured, except that the foregoing shall not apply to any Liens securing the Notes and the Note Guarantees.

Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding sentence shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the Incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “ Increased Amount ” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms, accretion of original issue discount or liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness.

SECTION 3.7     Limitation on Guarantees .

With respect to a Guarantee of any such Indebtedness of the Company or any Guarantor, if such Indebtedness is by its express terms subordinated in right of payment to the Notes or such Guarantor’s Note Guarantee, any such Guarantee by such

97

Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Note Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes or such Guarantor’s Note Guarantee.

(b)    Notwithstanding the foregoing, 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, (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 under applicable law, or (iii) to any Excluded Subsidiary.

(c)    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 not be required to comply with the 60-day period described in Section  3.7(a) above.

(d)     Each Note Guarantee shall be released in accordance with Section  10.2 hereof.

SECTION 3.8     Limitation on Affiliate Transactions .

(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 $40.0 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.

in each case, in a manner that complies in all material respects with the requirements specified in such form, except as described above or below and subject to exceptions consistent with the presentation of information in the Offering Memorandum; provided , however , that the Company shall not be required to (i) comply with Regulation G under the Exchange Act or Item 10(e) of Regulation S-K with respect to any “non-GAAP” financial information contained therein, (ii) provide any information that is not otherwise similar to information currently included in the Offering Memorandum or (iii) provide separate financial statements or other information contemplated by Rule 3-09 or Rule 3-10 of Regulation S-X, or in each case any successor provisions. In addition, notwithstanding the foregoing, the Company will not be required to (i) comply with Sections 302, 906 and 404 of the Sarbanes-Oxley Act of 2002, as amended, or (ii) otherwise furnish any information, certificates or reports required by Items 307 or 308 of Regulation S-K. 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 hereof if Holders of at least 30.0% 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 shall agree that, for so long as any Notes are outstanding, it shall 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.

105

(b)    If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries and such Unrestricted Subsidiaries hold in the aggregate more than 5.0% of the Total Assets of the Company, then the annual and quarterly financial information required by Section  3.10(a)(1) and (2)  will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

(c)    Substantially concurrently with the furnishing or making such information available to the Trustee pursuant to Section  3.10(a) hereof, the Company shall also use its commercially reasonable efforts to post copies of such information required by Section  3.10(a) hereof 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, in the case of securities analysts and market making financial institutions, reasonably satisfactory to the Company. To the extent the Company determines in good faith that it cannot make such reports available in the manner described in the preceding sentence after the use of its commercially reasonable efforts, the Company shall furnish such reports to the Holders of the Notes, upon their request. The Company may condition the delivery of any such reports to such Holders, prospective investors in the Notes, and securities analysts and market making financial institutions on the agreement of such Persons to (i) treat all such reports (and the information contained therein) and information as confidential, (ii) not use such reports and the information contained therein for any purpose other than their investment or potential investment in the Notes and (iii) not publicly disclose any such reports (and the information contained therein) and information.

(d)    If at any time the Company shall cease to have a class of securities registered under Section 12 of the Exchange Act, the Company will be required to hold quarterly conference calls for the Holders of Notes, prospective investors in the Notes and securities analysts and market making financial institutions, 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 (or as applicable, any Parent Entity’s) equity investors and analysts). The conference call, if required pursuant to the preceding sentence, will be following the last day of each fiscal quarter of the Company and not later than ten (10) Business Days from the time that the Company distributes the financial information as set forth in Section  3.10(a)(1) or (2), as applicable . No fewer than two days prior to any such 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 and market making financial institutions to obtain access to such call. For the avoidance of doubt, the requirements of this Section  3.10(d) shall not apply so long as the Company has a class of securities registered under Section 12 of the Exchange Act.

106

(e)    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 a Parent Entity; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such Parent Entity (and other direct or indirect Parent Entities included in such information, if any), on the one hand, and the information relating to the Company and its Restricted Subsidiaries on a standalone basis, on the other hand. For the avoidance of doubt, the consolidating information referred to in the proviso in the preceding sentence need not be audited.

(f)    Notwithstanding anything to the contrary set forth in this Section  3.10 , if the Company or any Parent Entity of the Company has filed with the SEC the reports described in the preceding paragraphs with respect to the Company or any Parent Entity, the Company shall be deemed to be in compliance with the provisions of this Section  3.10 , relating to the filing or furnishing of such reports (and, for avoidance of doubt, will not be required to separately furnish such reports to the Holders of the Notes or post such reports to its website, IntraLinks or otherwise). It is understood that the Trustee shall have no responsibility to determine if such reports have been filed with the SEC, posted on any website or otherwise furnished to the Holders.

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

SECTION 3.11     [Reserved] .

SECTION 3.12     Maintenance of Office or Agency .

The Company 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. The corporate trust office of the Trustee, which initially shall be located at Wilmington Trust, National Association, 246 Goose Lane, Suite 105, Guilford, Connecticut 06347, Attention: GCP Applied Technologies Inc. Administrator, shall be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company 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 Company 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 or served at the corporate trust office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations and surrenders.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation. The Company 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. The office of the Trustee shall not be an office or agency of the Company for the purposes of service of legal process on the Company or any Guarantor.

107

SECTION 3.13     Existence . The Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its legal existence; provided, that the foregoing shall not prohibit any transaction permitted under Article IV or restrict the ability of the Company to convert to (or take similar action to become) another form of legal entity; provided, further, that the Company shall not be required to preserve or keep in full force and effect its legal existence if the Company shall determine (i)  that the preservation or keeping thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Company and its Restricted Subsidiaries, taken as a whole or (ii) the failure to preserve or keep in full force and effect such legal existence is not adverse in any material respect to the Holders of the Notes.

SECTION 3.14     Payment of Taxes . The Company will pay, and will cause each of its Restricted Subsidiaries to pay, prior to delinquency, all of its and their, as applicable, taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

SECTION 3.15     [Reserved] .

SECTION 3.16     Compliance Certificate . The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officer’s Certificate, the signer 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 Company is taking or proposes to take with respect thereto.

SECTION 3.17     Further Instruments and Acts . Upon request of the Trustee or as necessary to comply with future developments or requirements, the Company 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     [Reserved] .

SECTION 3.19     Statement by Officers as to Default . The Company shall deliver to the Trustee, as soon as possible and in any event within 30 days after the Company becomes 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 Company is taking or proposes to take with respect thereto.

108

SECTION 3.20     Designation of Restricted and Unrestricted Subsidiaries . 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 Investment”, 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 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 an Officer’s Certificate certifying that such designation complies with the preceding conditions and was permitted by 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 as of such date and, if such Indebtedness is not permitted to be Incurred as of such date by Section  3.2 , the Company will be in default of such covenant.

The Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section  3.2 (including pursuant to clause 5(ii) thereof treating such redesignation as an acquisition for the purpose of such clause), 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 Company shall be evidenced to the Trustee by an Officer’s Certificate certifying that such designation complies with the preceding conditions.

SECTION 3.21     Suspension of Certain Covenants on Achievement of Investment Grade Status . 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 continuing until the Reversion Date, the Company and its 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) (collectively, the “ Suspended Covenants ”).

If at any time the Notes cease to have such Investment Grade Status, then the Suspended Covenants will thereafter be reinstated as if such covenants had never been suspended (the “ Reversion Date ”) and be applicable pursuant to the terms of the Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the Indenture), unless and until the Notes subsequently attain Investment Grade Status and no Default or Event of Default is in existence (in which event the Suspended Covenants shall no longer be in effect for such time that the Notes maintain an Investment Grade Status);

109

provided , however , that no Default, Event of Default or breach of any kind shall be deemed to exist under the Indenture, the Notes or the Note Guarantees with respect to the Suspended Covenants based on, and none of the Company or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period, or any actions taken at any time pursuant to any contractual obligation arising prior to the Reversion Date, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period. The period of time between the date of suspension of the covenants and the Reversion Date is referred to as the “ Suspension Period ”.

On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section  3.2(b)(4)(ii) . On and 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 prior to, but not during, the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will not reduce the amount available to be made as Restricted Payments under Section  3.3(a)(iii) . On the Reversion Date, the amount of Excess Proceeds shall be reset at zero. Any Affiliate Transaction entered into after the Reversion Date pursuant to an agreement entered into during any Suspension Period will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section  3.8(b)(6 ). Any encumbrance or restriction on the ability of any Restricted Subsidiary to take any action described in Section  3.4(a)(1) through (3)  that becomes effective during the Suspension Period will be deemed to have existed on the Issue Date, so that it is classified as permitted under Section  3.4(b)(1) . In addition, within 60 days of the Reversion Date, the Company must comply with Section  3.7 .

On and after each Reversion Date, the Company and its Subsidiaries will be permitted to consummate the transactions contemplated by any contract entered into during the Suspension Period, so long as such contract and such consummation would have been permitted during such Suspension Period.

The Company, in an Officer’s Certificate, shall provide the Trustee notice of any suspension of covenants under this Indenture pursuant to this Section  3.21 and of any occurrence of a Reversion Date. The Trustee will have no obligation to (i) independently determine or verify if such events have occurred or (ii) make any determination regarding the impact of actions taken during the Suspension Period on the Company’s future compliance with its covenants. In addition, the Trustee shall have no duty to monitor the ratings of the Notes, shall not be deemed to have any knowledge of the ratings of the Notes and shall have no duty to notify Holders if the Notes achieve Investment Grade Status.

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

SECTION 6.4     Waiver of Past Defaults . The Holders of a majority in aggregate principal amount of the outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, (a) waive, by their consent (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), an existing Default or Event of Default and its consequences under this Indenture except (i) a Default or Event of Default in the payment of the principal of, or interest, on a Note held by a non-consenting Holder

120

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 those arising as a result of nonpayment of principal, premium, if any, or interest that has become due solely because of the acceleration, (3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid, (4) the Company has paid the Trustee its compensation and reimbursed the Trustee for its reasonable expenses, disbursements and advances and (5) in the event of the cure or waiver of an Event of Default of the type described in clause (4) of Section  6.1(a) , the Trustee shall have received an Officer’s Certificate and an Opinion of Counsel stating that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

SECTION 6.5     Control by Majority . The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee 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 determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability; provided , however , that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any such action hereunder, the Trustee 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 or the Notes unless:

(3)    such Holders have offered in writing and, if requested, provided to 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.

121

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 contractual right of any Holder to receive payment of interest on the Notes held by such Holder or to institute suit for the enforcement of any such payment on or with respect to such Holder’s Notes after the due date therefor shall not be impaired or affected without the consent of such Holder (and, for the avoidance of doubt, the amendment, supplement or modification in accordance with the terms of this Indenture of Articles III and IV and Sections 6.1(a)(3) , (4) , (6) and (7)  and the related definitions shall be deemed not to impair the contractual right of any Holder to receive payments 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 Note).

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

SECTION 6.10     Priorities .

FIRST: to the Trustee for amounts due to it under Section  7.7 ;

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 Company, a suit by a Holder pursuant to Section  6.7 or a suit by Holders of more than 10.0% in outstanding principal amount of the Notes.

126

SECTION 7.7     Compensation and Indemnity .

The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including, but not limited to, costs of collection, costs of preparing reports, certificates and other documents, costs of preparation and mailing of notices to Holders. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the agents, counsel, accountants and experts of the Trustee. The Company shall indemnify the Trustee, its directors, officers, employees and agents against any and all loss, liability, damages, claims or expense, including taxes (other than taxes based upon the income of the Trustee) (including reasonable attorneys’ and agents’ fees and expenses) incurred by it without willful misconduct or gross negligence, as determined by a final nonappealable order of a court of competent jurisdiction, on its part in connection with the administration of this trust and the performance of its duties hereunder and under the Notes, including the costs and expenses of enforcing this Indenture (including this Section  7.7 ) and the Notes and of defending itself against any claims (whether asserted by any Holder, the Company or otherwise). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity of which it has received written notice. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall provide reasonable cooperation at the Company’s expense in the defense. The Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel; provided that the Company shall not be required to pay the fees and expenses of such separate counsel if it assumes the Trustee’s defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Company and the Trustee in connection with such defense.

To secure the Company’s payment obligations in this Section  7.7 , the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Notes. Such lien shall survive the satisfaction and discharge of this Indenture. The Trustee’s respective right to receive payment of any amounts due under this Section  7.7 shall not be subordinate to any other liability or Indebtedness of the Company.

The Company’s payment obligations pursuant to this Section  7.7 shall survive the discharge of this Indenture and any resignation or removal of the Trustee under Section  7.8 . Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs fees, expenses or renders services after the occurrence of a Default specified in clause (5) of Section  6.1(a) , the fees and expenses (including the reasonable fees and expenses of its 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 Company in writing not less than 30 days prior to the effective date of such resignation. The Holders of a majority in principal amount of then outstanding 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 Company’s

127

written consent, which consent will not be unreasonably withheld. The Company shall remove the Trustee if:

(1)    the Trustee fails to comply with Section  7.3 or Section  7.10 hereof;

(2)    the Trustee is adjudged bankrupt or insolvent;

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

(4)    the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed by the Company 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 Company shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall, at the expense of the Company, 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 10.0% in principal amount of the Notes may petition, at the Company’s 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 Company’s 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

128

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. 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.

SECTION 7.11     [Reserved] .

SECTION 7.12     Trustee’s Application for Instruction from the Company . Any application by the Trustee for written instructions from the Company 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 Company actually receives such application, unless any such Officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

ARTICLE VIII

LEGAL DEFEASANCE AND COVENANT

DEFEASANCE

SECTION 8.1     Option to Effect Legal Defeasance or Covenant Defeasance; Defeasance . The Company may, at its 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 Company’s exercise under Section  8.1 hereof of the option applicable to this Section  8.2 , the Company and each of the Guarantors will, subject to the satisfaction of the applicable 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 Note Guarantees) on the date such conditions set forth below are satisfied (hereinafter, “ Legal Defeasance ”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section  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 the Note Documents (and the Trustee, on written demand of and at the expense

129

of the Company, shall execute such instruments reasonably requested by the Company 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, on the Notes when such payments are due solely out of the trust referred to in Section  8.4 hereof;

(2)    the Company’s obligations with respect to the Notes under Article II concerning issuing temporary Notes, registrations of 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 Company’s or Guarantors’ obligations in connection therewith; and

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

The Company at its option at any time may exercise under Section  8.1 hereof the option applicable to this Section  8.2 notwithstanding its prior exercise of the option applicable to Section  8.3 hereof.

SECTION 8.3     Covenant Defeasance . Upon the Company’s exercise under Section  8.1 hereof of the option applicable to this Section  8.3 , the Company and each of the Guarantors will, subject to the satisfaction of the applicable conditions set forth in Section  8.4 hereof, be released from each of their obligations under the covenants contained in Section  3.2 , 3.3 , 3.4 , 3.5 , 3.6 , 3.7 , 3.8 , 3.9 , 3.10 , 3.16 , 3.19 , 3.21 and Section  4.1 (except Section  4.1(a)(1) ) hereof with respect to the outstanding Notes on and after the date such 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 Note Guarantees, the Company 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(a) hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section  8.1 hereof of the option applicable to this Section  8.3 , subject to the satisfaction of the applicable conditions set forth in Section  8.4 hereof, Sections 6.1(a)(3) (other than with respect to Section  4.1(a)(1) ), 6.1(a)(4) , 6.1(a)(5) (with respect only to any Significant Subsidiary (or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary)), 6.1(a)(6) , and 6.1(a)(7) hereof shall not constitute Events of Default.

130

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 Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in Dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient (in the case of U.S. Government Obligations or a combination of cash in Dollars and U.S. Government Obligations, in the opinion of a nationally recognized firm of independent public accountants, a nationally recognized investment bank or a nationally recognized appraisal or valuation firm) to pay the principal of and premium, if any, and interest, due on the Notes on the stated maturity date or on the applicable redemption date, as the case may be, and the Company must specify whether such Notes are being defeased to maturity or to a particular redemption date;

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

(A)    the Company has 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 to the effect that, and based thereon such Opinion of Counsel in the United States shall state that, subject to customary assumptions and exclusions, the Holders, in their capacity as Holders, will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and Legal Defeasance and will be subject to U.S. federal income tax in the same amounts and in the same manner and at the same times as would have been the case if such deposit and Legal Defeasance had not occurred;

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

(6)    [reserved];

131

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

(8)    the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel in the United States (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for or relating to Legal Defeasance or 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 the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company 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.

Notwithstanding anything in this Article VIII to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company 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, a nationally recognized investment bank or a nationally recognized appraisal or valuation firm, 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 Company . Subject to applicable law, any money deposited with the Trustee or any Paying Agent, or then held by the Company or the Guarantors in trust for the payment of the principal of, premium or interest on, any Note that is not applied but remains unclaimed by the Holder of such Note for two years after such principal, premium or interest has become due and payable shall be repaid to the Company on its written request, or if such money is then held by the Company or the Guarantors in trust, such money shall be released from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company and the Guarantors for payment thereof as general creditors unless applicable 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 Company as trustee thereof, will thereupon cease; provided , however , that the Trustee or such Paying Agent, before being

132

required to make any such repayment, shall at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which 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 Company.

SECTION 8.7     Reinstatement . If the Trustee or Paying Agent is unable to apply any money or 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 Company’s and the Guarantors’ obligations under this Indenture and the Notes and the Note 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 Company make any payment of principal of, premium, or interest on, any Note following the reinstatement of its obligations, the Company 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.

ARTICLE IX

SECTION 9.1     Without Consent of Holders . Notwithstanding Section  9.2 of this Indenture, the Company, any Guarantor, if applicable, and the Trustee may amend, supplement or modify this Indenture, any Note Guarantee and the Notes without the consent of any Holder:

(1)    to cure any ambiguity, omission, mistake, defect, error or inconsistency, conform any provision to any provision under the heading “Description of Notes” in the Offering Memorandum or reduce the minimum denomination of the Notes;

(6)    to make any change that does not adversely affect the rights of any holder of any series of debt securities, including the Notes, in any material respect;

(7)    to change or eliminate any provisions of this Indenture so long as there are no Holders entitled to the benefit of the provisions;

133

(8)    at the Company’s election, to comply with any requirement of the SEC in connection with the qualification of this Indenture under the TIA, if such qualification is required;

(9)    to make such provisions as necessary (as determined in good faith by the Company) for the issuance of Additional Notes;

(10)    to provide for any Restricted Subsidiary to provide a Note Guarantee in accordance with Section  3.7 , 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;

(11)    to 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;

(12)    to supplement any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Notes so long as any such action shall not adversely affect the interests of any Holder of such series of Notes or any other series of debt securities issued thereunder;

(13)    to comply with Section  4.1 hereof;

(14)    in the case of subordinated debt securities, to make any change to the provisions of this Indenture or any supplemental indenture relating to subordination that would limit or terminate the benefits available to any holder of senior Indebtedness under such provisions (but only if each such holder of senior Indebtedness under such provisions consents to such change); or

(15)    to 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 other applicable securities law and (ii) such amendment does not adversely affect the rights of Holders to transfer Notes in any material respect.

Subject to Section  9.2 , upon the request of the Company and upon receipt by the Trustee of the documents described in Sections 9.6 and 12.4 hereof, the Trustee will join with the Company and the Guarantors, if applicable, in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties, liabilities 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 Company shall provide to Holders a notice briefly describing such amendment or supplement,

134

which the Company may do by making such notice publicly available by filing with the SEC. The failure to provide 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 Company, the Guarantors, if applicable, and the Trustee may amend or supplement this Indenture, any Note Guarantee and the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, such 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, 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 and the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of or tender offer or exchange offer for such Notes). Section  2.12 hereof and Section  12.4 hereof shall determine which Notes are considered to be “outstanding” for the purposes of this Section  9.2 .

Upon the request of the Company 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 12.4 hereof, the Trustee will join with the Company and the Guarantors, if applicable, in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties, liabilities 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.

Without the consent of each Holder of Notes affected, an amendment, supplement or waiver may not, with respect to any Notes 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 );

(3)    reduce the principal of or extend the Stated Maturity of 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 ;

(5)    make any such Note payable in currency other than that stated in such Note;

(6)    impair the contractual 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

135

for the enforcement of any such payment on or with respect to such Holder’s Notes (and, for the avoidance of doubt, the amendment, supplement or modification in accordance with the terms of this Indenture of Articles III and IV and Sections 6.1(a)(3) , (4) , (6) and (7)  and the related definitions shall be deemed not to impair the contractual 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 Note);

(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); or

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

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 purchase of, or tender offer or exchange offer for, such Holder’s Notes will not be rendered invalid by such purchase, tender or exchange.

After an amendment or supplement under this Section  9.2 becomes effective, the Company shall provide to Holders a notice briefly describing such amendment or supplement, which the Company may do by making such notice publicly available by filing with the SEC. The failure to provide 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 this Indenture . Every amendment or supplement to this Indenture, any Note Guarantee and the Notes will be set forth in an amended or supplemental indenture that complies with this Indenture 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 Company 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

136

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 Company in exchange for all Notes may issue and the Trustee shall, upon receipt of a Company 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 authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. 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  12.2 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 Company in accordance with its terms.

ARTICLE X

GUARANTEE

SECTION 10.1     Guarantee . Subject to the provisions of this Article X , each Guarantor hereby fully, unconditionally and irrevocably guarantees (the “ Note Guarantees ”), as primary obligor and not merely as surety, jointly and severally with each other Guarantor on an unsecured, unsubordinated basis, to each Holder of the Notes, and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest on the Notes and all other obligations and liabilities of the Company under this Indenture (including without limitation interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Company or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding and the obligations under Section  7.7 ) (all the foregoing being hereinafter collectively called the “ Guaranteed Obligations ”). Each Guarantor agrees that the Guaranteed Obligations of such Guarantor 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 Note Guarantees will rank senior in right of payment to such other Indebtedness.

137

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

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 Company or any other person under this Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (d) the release of any security held by any Holder 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 the Company; (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 Note Guarantee herein shall remain in full force and effect until payment in full of all the Guaranteed Obligations or such Guarantor is released from its Note Guarantee in compliance with Section  10.2 , Article VIII or Article XI . Each Guarantor further agrees that its Note Guarantee herein shall continue to be effective or be reinstated, as the

138

case may be, if at any time payment, or any part thereof, of principal of, premium, if any, or interest on any of the Guaranteed Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company 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 the Company to pay any of the Guaranteed Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee on behalf of the Holders an amount equal to the sum of (i) the unpaid amount of such Guaranteed Obligations then due and owing and (ii) accrued and unpaid interest on such Guaranteed Obligations then due and owing (but only to the extent not prohibited by law) (including interest accruing after the filing of any petition in bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the Company 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 Note Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guaranteed Obligations, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purposes of this Note Guarantee.

Each Guarantor also agrees to pay any and all fees, costs and expenses (including attorneys’ fees and expenses) incurred by the Trustee or the Holders in enforcing any rights under this Section  10.1 .

SECTION 10.2     Limitation on Liability; Termination, Release and Discharge .

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

(b)    The Note Guarantee of a Guarantor shall be automatically and unconditionally terminated, released and discharged upon:

(1)    a sale or other disposition (including by way of consolidation, merger or amalgamation) of (i) the Capital Stock of such Guarantor as a result of which such

139

Guarantor ceases to be a Restricted Subsidiary or (ii) all or substantially all the assets of the Guarantor to a Person other than to the Company or a Restricted Subsidiary and as 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;

This Indenture will be discharged and will cease to be of further effect (except as to surviving rights of transfer or exchange of the Notes and indemnification rights of the Trustee, as expressly provided for in this Indenture) as to all Notes issued hereunder, when:

(a)    either:

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

(2)    all such Notes not theretofore delivered to the Trustee for cancellation (i) have become due and payable by reason of the making of a notice of redemption or otherwise, (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 Company;

(b)    the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in Dollars, U.S. Government Obligations, or a combination thereof, as applicable, 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; provided that upon any redemption that requires the payment of the Applicable Premium, the amount deposited shall be sufficient for purposes of this Indenture to the extent that an amount is deposited with the Trustee equal to the Applicable Premium with respect to the Notes calculated as of the earlier of the date on which arrangements referred to in the foregoing clause (a)(2)(iii) are entered into and the date of the notice of redemption, with any deficit as of the date of the redemption only required to be deposited with the Trustee on or prior to the date of the redemption;

(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 shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit;

SECTION 11.2     Application of Trust Money . Subject to the provisions of Section  8.6 hereof, all money in Dollars or U.S. Government Obligations 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 the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium) and interest for whose payment such money in Dollars or U.S. Government Obligations has been deposited with the Trustee; but such money in Dollars or U.S. Government Obligations 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 Company’s 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 Company has made any payment of principal of, premium or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

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.

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.

The Company or any Guarantor may act as Paying Agent, Registrar or transfer agent.

The Company issued the Notes under an Indenture dated as of April 10, 2018 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “ Indenture ”), among the Company, the guarantors named therein and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all terms and provisions of the Indenture, and Holders are referred to the Indenture for a statement of those terms. In the event of a conflict between the terms of the Notes and the terms of the Indenture, the terms of the Indenture shall control.

The Notes are unsecured, unsubordinated obligations of the Company. The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is unlimited. This Note is one of the 5.500% Senior Notes due 2026 referred to in the Indenture. The Notes include (i) $350,000,000 principal amount of the Company’s 5.500% Senior Notes due 2026 issued under the Indenture on April 10, 2018 (the “ Initial Notes ”) and (ii) if and when issued, additional Notes that may be issued from time to time under the Indenture subsequent to April 10, 2018 (the “ Additional Notes ”) as provided in Section  2.1(a) of the Indenture. The Initial Notes and the Additional Notes shall be part of the same class for all purposes of the Indenture; provided that Additional Notes will not be issued with the same CUSIP, ISIN or other identifying number as the Initial Notes unless such Additional Notes are fungible with the Initial Notes for U.S. federal income tax purposes.

The Notes shall be entitled to the benefits of Note Guarantees, if any, made for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantors, if any, the Trustee and the Holders, and for events causing release of the Guarantors, if any, from the Note Guarantees, if any.

153

The Company may redeem the Notes at any time and from time to time in whole or in part, subject to the terms and conditions set forth in Section  5.7 of the Indenture. The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

The Indenture provides that upon the occurrence of a Change of Control and subject to further limitations contained therein, the Company shall make an offer to repurchase outstanding Notes in accordance with the procedures set forth in the Indenture.

In accordance with Section 3.5 of the Indenture, the Company will be required to offer to purchase Notes upon the occurrence of certain events.

The Notes shall be issuable only in fully registered form in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any tax and fees required by law or permitted by the Indenture. The Company (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 sending of a notice of an offer to repurchase or notice of redemption of Notes and ending at the close of business on the day of such sending 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.

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

If money for the payment of the principal of, premium or interest on this Note remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request. After any such repayment, Holders entitled to the money must look only to the Company and the Guarantors for payment thereof as general creditors unless applicable abandoned property law designates another Person.

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

154

Subject to certain exceptions contained in the Indenture, the Indenture, the Note Guarantees 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 Company, the Guarantors and the Trustee may amend or supplement the Indenture, any Note Guarantees and the Notes as provided in the Indenture.

Events of Default are set forth in the Indenture. If an Event of Default (other than an Event of Default described in clause (5) of Section 6.1(a) of the Indenture with respect to the Company) occurs and is continuing, the Trustee by written notice to the Company, or the Holders of at least 30.0% in principal amount of the outstanding Notes by written notice to the Company and the Trustee, may declare the principal of and accrued and unpaid interest, if any, on all the Notes to be due and payable. Upon such a declaration, such principal and accrued and unpaid interest, if any, will be due and payable immediately. If an Event of Default described in clause (5) of Section  6.1(a) of the Indenture with respect to the Company occurs and is continuing, the principal of and accrued and unpaid 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. Under certain circumstances set forth in Section  6.4 of the Indenture, Holders of a majority in aggregate principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences under the Indenture.

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 Company, 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 Company and its Affiliates and Subsidiaries; provided , however , that if the Trustee acquires any conflicting interest, 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.

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

155

This Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent acting on its behalf) manually authenticates 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 Company has caused CUSIP and ISIN numbers, if applicable, to be printed on the Notes and has 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 correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or purchase and reliance may be placed only on the other identification numbers printed on the Notes.

This Note shall be governed by, and construed in accordance with, the laws of the State of New York.

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

The undersigned represents and warrants to you that:

1.    We are an institutional “accredited investor” within the meaning of 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 in accordance with all applicable securities laws of the United States and other jurisdictions, 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.

If any resale or other transfer of the Notes is proposed to be made pursuant to clause (e) above, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Issuer 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 Issuer and the Trustee reserve the right prior to the offer, sale or other transfer of the Notes pursuant to clause (c), (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Issuer and the Trustee.
