The Issuer has duly authorized the creation of an issue of 3.625% Senior Unsecured Notes due 2029 issued on the date hereof (the 'InitialNotes') and, to provide therefor, the Issuer and the Guarantors have duly authorized the execution and delivery of this Indenture.

All things necessary to make the Notes (as defined herein), when executed by the Issuer and authenticated and delivered hereunder and duly issued by the Issuer, the valid and legally binding obligations of the Issuer and to make this Indenture a valid and legally binding agreement of the Issuer, in accordance with their and its terms, have been done.

Each of the parties hereto is entering into this Indenture for the benefit of the other parties and for the equal and ratable benefit of the Holders (as defined below) of (i) the Initial Notes and (ii) any Additional Notes (as defined herein) that may be issued from time to time under this Indenture.

NOW, THEREFORE, THIS INDENTURE WITNESSETH:

For and in consideration of the premises and the purchase of the Notes by the Holders thereof, it is mutually covenanted and agreed, for the equal and ratable benefit of all Holders, as follows:

(2)

all accounting terms not otherwise defined herein have the meanings assigned to them in accordance with GAAP (as defined herein);

(3)

the words 'herein', 'hereof' and 'hereunder' and other words of similar import refer to this Indenture as a whole and not to any particular Article, Section or other subdivision;

(4)

all references to Articles, Sections, Exhibits and Appendices shall be construed to refer to Articles and Sections of, and Exhibits and Appendices to, this Indenture;

(7)

all references to the date the Notes were originally issued shall refer to the Issue Date; and

(8)

any reference to interest on, or in respect of, any Note in this Indenture shall be deemed to include Additional Interest if, in such context, Additional Interest is, was or would be payable pursuant to Section 503; any express mention of Additional Interest in any provision of this Indenture shall not be construed as excluding Additional Interest in those provisions of this Indenture where such express mention is not made.

(b) When calculating the availability under any basket or ratio under this Indenture, in each case for any purpose in connection with a Limited Condition Acquisition, the date of determination of such basket or ratio and of any Default may, at the option of the Issuer, be the date the definitive agreement(s) for such Limited Condition Acquisition is entered into. Any such ratio or basket shall be calculated on a pro forma basis after giving effect to such Limited Condition Acquisition and other transactions in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof and the granting, creation, incurrence or suffering to exist of any Lien) as if they had been consummated at the beginning of the applicable period for purposes of determining the ability to consummate any such Limited Condition Acquisition; provided, however, that if the Issuer elects to make such determination as of the date of such definitive agreement(s), then (i) if any of such ratios are no longer complied with or baskets are exceeded as a result of fluctuations in such ratio (including due to fluctuations in EBITDA or other financial result or metric of the Issuer or the target company) or basket subsequent to such date of determination and at or prior to the consummation of the relevant Limited Condition Acquisition, such ratios or baskets will not be deemed to have been breached or exceeded as a result of such fluctuations solely for purposes of determining whether the Limited Condition Acquisition is permitted under this Indenture and (ii) such ratios or baskets shall not be tested at the time of consummation of such Limited Condition Acquisition or related transactions; providedfurther, however, that if the Issuer elects to have such determinations occur at the time of entry into such definitive agreement(s), any such transactions (including any incurrence of Indebtedness and the use of proceeds thereof and the granting, creation, incurrence or suffering to exist of any Lien) shall be deemed to have occurred on the date the definitive agreement(s) is entered into and shall be deemed outstanding thereafter for purposes of calculating any ratios or baskets under this Indenture after the date of such definitive agreement(s) and before the consummation of such Limited Condition Acquisition, unless such definitive agreement(s) is terminated or such Limited Condition Acquisition or incurrence of Indebtedness or such other transaction to which pro forma effect is being given is abandoned or with respect to which the Issuer has delivered an Officer's Certificate to the Trustee stating that such transaction will not occur.

For purposes of this definition, 'control', as used with respect to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise.

'Agent' means any Note Registrar, Transfer Agent, co-registrar, Notes Custodian, Paying Agent or other agent appointed in accordance with this Indenture to perform any function that this Indenture authorized such agent to perform.

'Aggregate Net Availability Debt' means, as of any date of determination, the sum of the following (in each case without duplication): (a) the then outstanding aggregate principal amount of Indebtedness of the Issuer and its Subsidiaries incurred pursuant to clause (10) of the definition of 'Permitted Liens'; plus (b) the then outstanding aggregate principal amount of all Subsidiary Debt incurred after the Issue Date pursuant to Section 1011(a)(12); provided that, any such Subsidiary Debt will be excluded from this clause (b) to the extent that such Subsidiary Debt (or the related Indebtedness) is included in clause (a) or (c) of this definition; plus (c) the then existing Attributable Debt of the Issuer and its Subsidiaries in respect of Sale and Leaseback Transactions entered into after the Issue Date pursuant to Section 1012(c); provided that any such Attributable Debt will be excluded from this clause (c) to the extent of Indebtedness relating thereto is included in clause (a) or (b) of this definition; provided, further, in no event will the amount of any Indebtedness (including Guarantees of such Indebtedness) be required to be included in the calculation of Aggregate Net Availability Debt more than once despite the fact that more than one Person is obligated with respect to such Indebtedness and despite the fact that such Indebtedness is secured by the assets of more than one Person (for example, in the case where more than one Subsidiary has Guaranteed or otherwise become liable for such Indebtedness or in the case where there are Liens on assets of one or more of the Issuer and its Subsidiaries securing such Indebtedness or one or more Guarantees thereof, the amount of Indebtedness so Guaranteed or secured shall only be included once in the calculation of Aggregate Net Availability Debt); minus (d) the aggregate amount of cash and Company Cash Equivalents of the Issuer and its Subsidiaries (other than any Future Escrow Subsidiary) as of such date (but disregarding the proceeds of Indebtedness that is incurred on such date).

For purposes of calculating the amount of 'Aggregate Net Availability Debt' for purposes of clause (10) of the definition of 'Permitted Liens', Section 1011(a)(12) and Section 1012(c), the Issuer may elect, pursuant to an Officer's Certificate delivered to the Trustee, to treat all or any portion of the commitment under any Indebtedness which is to be incurred or secured by such Lien, as the case may be, as being incurred as of the applicable date of determination and any subsequent incurrence of Indebtedness under such commitment that was so treated shall not be deemed to be an incurrence of additional Indebtedness or an additional Lien at such subsequent time; provided further, however, that such committed amount shall be treated as outstanding Indebtedness (whether or not outstanding) for each subsequent calculation of the 'Aggregate Net Availability Debt' hereunder for so long as such Indebtedness is so designated. In addition, (i) any Future Escrow Debt shall be deemed to not constitute Aggregate Net Availability Debt and (ii) any Permitted Revolving Indebtedness shall be deemed to not constitute Aggregate Net Availability Debt.

-3-

'Appendix' has the meaning specified in Section 201.

'Applicable Measurement Period' in effect at any time means the Issuer's most recently ended four fiscal quarters immediately preceding the applicable date of determination for which internal financial statements are available (as determined in good faith by the Issuer).

If since the beginning of such period any Person that subsequently became a Subsidiary of the Issuer or was merged with or into the Issuer or any Subsidiary of the Issuer since the beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation or disposed operation that would have required adjustment pursuant to this definition, then the applicable amount shall be calculated giving pro forma effect thereto for such Applicable Measurement Period as if such Investment, acquisition, disposition, merger, consolidation or disposed operation had occurred at the beginning of the Applicable Measurement Period.

(1)

1.00% of the then outstanding principal amount of such Note; and

(2)

the excess, if any, of (a) the present value at such Redemption Date of (i) the Redemption Price (such Redemption Price being set forth in the table appearing in Section 1101) of such Note at May 1, 2024, plus (ii) all required interest payments due on such Note through May 1, 2024 (excluding accrued interest to the Redemption Date), computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over (b) the then-outstanding principal amount of such Note.

Calculation of the Applicable Premium will be made by the Issuer or on behalf of the Issuer by such Person as the Issuer shall designate; provided, however, that such calculation or the correctness thereof shall not be a duty or obligation of the Trustee.

'Applicable Procedures' means, with respect to any payment, tender, redemption, transfer or exchange of or for beneficial interests in any Global Note, the rules and procedures of the Depositary that apply to such payment, tender, redemption, transfer or exchange.

'Attributable Debt' means, with respect to any Sale and Leaseback Transaction, at the time of determination, the lesser of (a) the sale price of the property so leased multiplied by a fraction the numerator of which is the remaining portion of the base term of the lease included in such transaction and the denominator of which is the base term of such lease, and (b) the total obligation (discounted to the present value at the implicit interest factor, determined in accordance with GAAP, included in the rental payments) of the lessee for rental payments (other than amounts required to be paid on account of property taxes as well as maintenance, repairs, insurance, water rates and other items which do not constitute payments for property rights) during the remaining portion of the base term of the lease included in such transaction. Notwithstanding the foregoing, if such Sale and Leaseback Transaction results in a Finance Lease Obligation, the amount of Indebtedness represented thereby will be determined in accordance with the definition of 'Finance Lease Obligation'.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Issuer or any Guarantor in reliance thereon, whether or not notation of such action is made upon such Note.

A copy of all notices to any Agent shall be sent to the Trustee at the address shown above. Any Person may change its address by giving notice of such change as set forth herein.

SECTION 107. Notice to Holders; Waiver. Where this Indenture provides for notice of any event to Holders by the Issuer or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and delivered electronically or mailed, first class postage prepaid, to each Holder affected by such event, at his address as it appears in the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Notices given by publication shall be deemed given on the first date on which publication is made; notices given by first-class mail, postage prepaid, shall be deemed given five calendar days after mailing; notices sent by overnight delivery service will be deemed given when delivered; and notices given electronically shall be deemed given when sent. Any notices required to be given to the Holders of Notes that are in global form will be given to the Depositary pursuant to Applicable Procedures.

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Issuer elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee's understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee's reliance upon and compliance with such instructions notwithstanding that such instructions conflict or are inconsistent with a subsequent written instruction. The Issuer agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

In case by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Holders may communicate pursuant to TIA Section 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Issuer, the Guarantors, the Trustee, each Agent and any other Person shall have the protection of TIA Section 312(c).

-30-

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

All agreements of each Guarantor in this Indenture will bind its successors, except as otherwise provided in Section 1208 hereof.

SECTION 110. Severability Clause. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111. Benefits of Indenture. Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto, any Agent, Paying Agent, any Note Registrar and their respective successors hereunder and the Holders any benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 112. Governing Law. This Indenture, the Notes and the Note Guarantees shall be governed by and construed in accordance with the laws of the State of New York. THE PARTIES HERETO AGREE TO SUBMIT TO THE JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH OF MANHATTAN, IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE NOTES.

SECTION 113. Legal Holidays. In any case where any Interest Payment Date, Redemption Date or Stated Maturity or Maturity of any Note shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Notes) payment of principal, and premium, if any, or interest need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date, or at the Stated Maturity or Maturity; provided, however, that no interest shall accrue for purposes of such payment for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or Maturity, as the case may be.

SECTION 114. No Personal Liability of Directors, Managers, Officers, Employees and Stockholders. No past, present or future director, manager, officer, employee, incorporator or stockholder of the Issuer or any Guarantor or any of their Subsidiaries, as such, shall have any liability for any obligations of the Issuer or the Guarantors under the Notes, the Note Guarantees or this 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 to the fullest extent permitted by applicable law. The waiver and release are part of the consideration for issuance of the Notes.

SECTION 115. Concerning the TIA. Except with respect to specific provisions of the TIA expressly referenced in the provisions of this Indenture, the TIA shall not be applicable to, and shall not govern, this Indenture and the Notes;

SECTION 116. Counterparts. This Indenture may be executed in any number of counterparts, each of which shall be original; but such counterparts shall together constitute but one and the same instrument. One signed copy is enough to prove this Indenture. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. This Indenture shall be valid, binding, and enforceable against a party when executed and delivered by an authorized individual on behalf of the party by means of (i) an original manual signature; (ii) a faxed, scanned, or photocopied manual signature, or (iii) any other electronic signature permitted by the federal Electronic Signatures in Global and National Commerce Act, state enactments of the Uniform Electronic Transactions Act, and/or any other relevant electronic signatures law, including any relevant provisions of the UCC (collectively, 'Signature Law'), in each case to the extent applicable. Each faxed, scanned, or photocopied manual signature, or other such electronic signature, shall for all purposes have the same validity, legal effect, and admissibility in evidence as an original manual signature. Each party hereto shall be entitled to conclusively rely upon, and shall have no liability with respect to, any faxed, scanned, or photocopied manual signature, or other such electronic signature, of any other party and shall have no duty to investigate, confirm or otherwise verify the validity or authenticity thereof. For the avoidance of doubt, original manual signatures shall be used for execution or indorsement of writings when required under the UCC or other Signature Law due to the character or intended character of the writings.

SECTION 117. USA PATRIOT Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account. The Issuer agrees that it will provide the Trustee with information about the Issuer as the Trustee may reasonably request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act.

SECTION 118. Waiver of Jury Trial. EACH OF THE ISSUER, ANY GUARANTOR AND THE TRUSTEE AND EACH HOLDER OF A NOTE, BY ITS ACCEPTANCE THEREOF, THEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREBY OR HEREBY.

SECTION 119. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation any act or provision of any present or future law or regulation or governmental authority, natural disaster, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, labor dispute, disease, epidemic or pandemic, quarantine, national emergency and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, communications system failure, malware or ransomware or other unavailability of the Federal Reserve Bank wire or facsimile or telex system or other funds transfer system or other wire or communication facility or unavailability of any securities clearing system; it being understood that the Trustee shall use reasonable efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

ARTICLE TWO

NOTE FORMS

SECTION 201. Form and Dating. Provisions relating to the Initial Notes are set forth in Appendix I attached hereto (the 'Appendix') which is hereby incorporated in, and expressly made part of, this Indenture. The Initial Notes and the Trustee's certificate of authentication shall be substantially in the form of Exhibit 1 to the Appendix which is hereby incorporated in, and expressly made a part of, this Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer is subject, if any, or usage (provided, however, that any such notation, legend or endorsement is in a form reasonably acceptable to the Issuer). Each Note shall be dated the date of its authentication. The terms of the Note set forth in the Appendix are part of the terms of this Indenture.

SECTION 202. Execution, Authentication, Delivery and Dating. The Notes shall be executed on behalf of the Issuer by at least one Officer. The signature of any Officer on the Notes may be manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Notes.

Notes bearing the manual or facsimile signature of an individual who was at any time the proper officer of the Issuer shall bind the Issuer, notwithstanding that such individual has ceased to hold such office prior to the authentication and delivery of such Notes or did not hold such office at the date of such Notes.

At any time and from time to time after the execution and delivery of this Indenture, the Issuer may deliver Notes executed by the Issuer to the Trustee for authentication, together with an Issuer Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Issuer Order shall authenticate and deliver such Notes.

On the Issue Date, the Issuer shall deliver the Initial Notes in the aggregate principal amount of $400,000,000 executed by the Issuer to the Trustee for authentication, together with an Issuer Order for the authentication and delivery of such Notes, specifying the principal amount and registered holder of each Note and directing the Trustee to authenticate the Notes and deliver the same to the persons named in such Issuer Order and the Trustee in accordance with such Issuer Order shall authenticate and deliver such Initial Notes. At any time and from time to time after the Issue Date, the Issuer may deliver Additional Notes executed by the Issuer to the Trustee for authentication, and in connection with any Automatic Exchange pursuant to Section 2.3(c)(vii) in the Appendix, the Global Note that is not a Transfer Restricted Note, together with an Issuer Order for the authentication and delivery of such Additional Notes, or Global Note that is not a Transfer Restricted Note in connection with such Automatic Exchange, specifying the principal amount of and registered holder of each Note, directing the Trustee to authenticate the Additional Notes, or Global Note that is not a Transfer Restricted Note in connection with such Automatic Exchange and deliver the same to the persons in such Issuer Order and the Trustee in accordance with such Issuer Order shall authenticate and deliver such Additional Notes, or Global Note that is not a Transfer Restricted Note in connection with such Automatic Exchange. In each case, the Trustee shall receive an Officer's Certificate and an Opinion of Counsel of the Issuer that it may reasonably require in connection with such authentication of Notes. Such Issuer Order shall specify the amount of Notes to be authenticated and the date on which such Notes are authenticated.

-33-

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.

In case the Issuer or any Guarantor, pursuant to Article Eight of this Indenture, shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into which the Issuer or such Guarantor shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed a supplemental indenture hereto with the Trustee pursuant to Article Eight of this Indenture, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, 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, but otherwise in substance of like tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Issuer Request of the successor Person, shall authenticate and deliver Notes as specified in such request 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 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.

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an affiliate of the Issuer.

ARTICLE THREE

THE NOTES

SECTION 301. Title and Terms. The aggregate principal amount of Notes which may be authenticated and issued under this Indenture is not limited; provided, however, that any Additional Notes issued under this Indenture are issued in accordance with Sections 202 and 313 hereof, as part of the same series as the Initial Notes.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture, and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

The Notes shall be known and designated as the '3.625% Senior Unsecured Notes Due 2029' of the Issuer. The Stated Maturity of the Notes shall be May 1, 2029, and the Notes shall bear interest at the rate of 3.625% per annum from the Issue Date, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, payable on November 1, 2021 and semiannually thereafter on May 1 and November 1 in each year and at said Stated Maturity, until the principal thereof is paid or duly provided for and to the Person in whose name the Note (or any Predecessor Note) is registered at the close of business on April 15 and October 15 immediately preceding such Interest Payment Date, whether or not a Business Day (each, a 'Regular Record Date').

-34-

The principal of, and premium, if any, and interest on, the Notes shall be payable at the offices or agencies of the Issuer set forth in Section 302, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders of the Notes at their respective addresses set forth in the Note Register; provided, however, that all payments of principal, premium, if any, and interest with respect to Notes represented by one or more permanent Global Notes registered in the name of or held by the Depositary will be made by wire transfer of immediately available funds to the Depositary.

Holders shall have the right to require the Issuer to purchase their Notes, in whole or in part, in the event of a Change of Control Repurchase Event pursuant to Section 1013.

The Notes shall be redeemable as provided in Article Eleven.

The due and punctual payment of principal of, and premium, if any, and interest on, the Notes payable by the Issuer is fully and unconditionally Guaranteed, to the extent set forth herein, by each of the Guarantors.

SECTION 302. Note Registrar, Transfer Agent and Paying Agent. The Issuer shall maintain one or more Paying Agents for the Notes in the continental United States. The Issuer hereby appoints the Trustee as the initial Paying Agent.

The Issuer shall be responsible for making calculations called for under the Notes, including but not limited to determination of Redemption Price or other amounts payable on the Notes. The Issuer will make the calculations in good faith and, absent manifest error, its calculations will be final and binding on the Holders. The Issuer will provide a schedule of its calculations to the Trustee when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Issuer's calculations without independent verification. The Trustee shall forward the Issuer's calculations to any Holder of the Notes upon the written request of such Holder.

The Issuer will also maintain one or more registrars (each, a 'Note Registrar') with offices in the continental United States. The Issuer will also maintain a transfer agent (each, a 'Transfer Agent') in the continental United States. The Issuer hereby appoints the Trustee as the initial Note Registrar and Transfer Agent. The Note Registrar and the Transfer Agent shall keep a register of the Notes and of their transfer and exchange (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the 'Note Register'). The Note Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Note Register shall be open to inspection by the Trustee. The Issuer may change the Paying Agents, the Note Registrars or the Transfer Agents without prior notice to the Holders. The Issuer may have one or more co-registrars and one or more additional paying agents. The term 'Note Registrar' includes any co-registrars.

If any Notes are listed on an exchange and the rules of such exchange so require, the Issuer will satisfy any requirement of such exchange as to paying agents, registrars and transfer agents and will comply with any notice requirements required under such exchange in connection with any change of Paying Agent, Registrar or Transfer Agent.

The Issuer shall enter into an appropriate agency agreement with any Note 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 Issuer shall notify the Trustee in writing of the name and address of any such Agent. If the Issuer fails to maintain a Note Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 607. The Issuer or any Affiliate thereof may act as Paying Agent or Note Registrar.

-35-

The Issuer acknowledges that neither the Trustee nor any Agent makes any representations as to the interpretation or characterization of the transactions herein undertaken for tax or any other purpose, in any jurisdiction.

SECTION 303. Denominations. The Notes shall be issuable only in registered form without coupons and only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

SECTION 304. Temporary Notes. Pending the preparation of definitive Notes, the Issuer may execute, and upon Issuer Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as conclusively evidenced by their execution of such Notes.

If temporary Notes are issued, the Issuer will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Issuer designated for such purpose pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuer shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes.

SECTION 305. Registration of Transfer and Exchange.

Upon surrender for registration of transfer of any Note at the office or agency of the Issuer designated pursuant to Section 1002, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations of a like aggregate principal amount.

At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive.

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange.

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Issuer or the Note Registrar) be duly endorsed, or be accompanied by written instruments of transfer, in form satisfactory to the Issuer and the Note Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. The transferor of any Note shall also provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Internal Revenue Code Section 6045. The Trustee may rely on information provided to it and shall have no

-36-

responsibility to verify or ensure the accuracy of such information. Neither the Note Registrar nor the Issuer will be required to register the transfer or exchange of any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or any Notes for a period of 15 days before a selection of Notes to be redeemed.

No service charge shall be made for any registration of transfer or exchange or redemption of Notes, but the Issuer may require payment of a sum sufficient to cover any taxes, fees or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Sections 202, 304, 906, 1013 or 1108 not involving any transfer.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Notes. If (a) any mutilated Note is surrendered to the Trustee, or (b) the Issuer and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Issuer and the Trustee such security or indemnity to save each of them harmless from any claim, loss, cost or liability resulting from such lost or stolen Note, then, in the absence of written notice to the Issuer or the Trustee that such Note has been acquired by a Protected Purchaser (as defined in Section 8-303 of the Uniform Commercial Code) (a 'Protected Purchaser'), the Issuer shall execute and upon Issuer Order the Trustee shall authenticate and deliver, 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 Issuer in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section, the Issuer may require the payment of 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 the Trustee) connected therewith.

Every new Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuer and each Guarantor, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 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 307. Payment of Interest; Interest Rights Preserved.

(a) 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 interest at the office or agency of the Issuer maintained for such purpose pursuant to Section 1002; provided, however, that, subject to Section 301 hereof, each installment of interest may at the Issuer's option be paid by mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 308, to the address of such Person as it appears in the Note Register; provided, however, that payment by wire transfer of immediately available funds shall be required with respect to principal of, premium, if any, and interest on, all Notes in global form and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuer and the Paying Agent at least ten days in advance of the applicable payment date.

-37-

(b) Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the Regular Record Date by virtue of having been such Holder, 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 'DefaultedInterest') may be paid by the Issuer, at its election in each case, as provided in clause (1) or (2) below:

(1)

the Issuer 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 for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Issuer shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Issuer shall promptly notify the Trustee of such Special Record Date, and in the name and at the expense of the Issuer, the Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided for in Section 107, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so given, such Defaulted Interest shall be paid 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 following clause (2); or

(2)

the Issuer 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 Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

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

SECTION 308. Persons Deemed Owners. Prior to the due presentment of a Note for registration of transfer, the Issuer, any Guarantor, the Trustee and any agent of the Issuer or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of, and premium, if any, and (subject to Sections 305 and 307) interest on, such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Issuer, the Trustee or any agent of the Issuer or the Trustee shall be affected by notice to the contrary.

-38-

SECTION 309. Cancellation. All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be cancelled by the Trustee in accordance with its customary procedures. The Issuer may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Issuer may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously authenticated hereunder which the Issuer has not issued and sold, and all Notes so delivered shall be cancelled by the Trustee in accordance with its customary procedures. If the Issuer shall so acquire any of the Notes, however, such acquisition shall not operate as a satisfaction of the indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures.

SECTION 310. Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 311. Transfer and Exchange. The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer. When a Note is presented to the Note Registrar or a co-registrar with a request to register a transfer, the Note Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Notes are presented to the Note Registrar or a co-registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Note Registrar shall make the exchange as requested if the same requirements are met.

SECTION 312. CUSIP, ISIN and Common Code Numbers. The Issuer in issuing the Notes may use CUSIP, ISINs and 'Common Code' numbers (in each case, if then generally in use) in addition to serial numbers, and, if so, the Trustee shall use such CUSIP, ISINs and 'Common Code' numbers in addition to serial numbers in notices of redemption, repurchase or other notices to Holders as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such CUSIP, ISINs and 'Common Code' numbers either as printed on the Notes or as contained in any notice of a redemption or repurchase or other notice and that reliance may be placed only on the serial or other identification numbers printed on the Notes, and any such redemption or repurchase or other notice shall not be affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee in writing of any change in the CUSIP, ISINs and 'Common Code' numbers applicable to the Notes.

SECTION 313. Issuance of Additional Notes. The Issuer may issue additional Notes having identical terms and conditions to the Initial Notes issued on the Issue Date (the 'AdditionalNotes'). The Initial Notes issued on the Issue Date and any Additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture; provided, however, that Additional Notes will not be issued with the same CUSIP, if any, as Initial Notes unless such Additional Notes are fungible with Initial Notes for U.S. Federal income tax purposes.

in respect of clause (1)(B), no Default has occurred and is continuing on the date of the deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the

-40-

deposit shall not result in a breach or violation of, or constitute a default under any other instrument to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings);
(3)

the Issuer or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture;

(4)

the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Notes at the Stated Maturity or on the Redemption Date, as the case may be; and

(5)

the Issuer has delivered to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that all conditions precedent herein to the satisfaction and discharge of this Indenture have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Issuer to the Trustee under Section 607, the obligations of the Issuer to any Authenticating Agent under Section 612 and, if money or Government Securities shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive such satisfaction and discharge.

SECTION 402. Application of Trust Money. Subject to the provisions of the last paragraph of Section 1003, all money or Government Securities deposited with the Trustee pursuant to Section 401 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 Issuer acting as its own Paying Agent) of the principal (and premium, if any) and interest for whose payment such money or Government Securities has been deposited with the Trustee; but such money or Government Securities 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 Government Securities in accordance with Section 401 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 Issuer'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 401 until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 401; provided, however, that if the Issuer has made any payment of principal of, and premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

(A) is caused by a failure to make principal payments (including a payment at final maturity) aggregating in excess of $75.0 million on any such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a 'PaymentDefault'); or

(B) results in the acceleration of such Indebtedness prior to its express stated maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $75.0 million or more at one time outstanding;

-43-

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

(a) If any Event of Default (other than an Event of Default specified in Section 501(9) above with respect to the Issuer) occurs and is continuing, the Trustee or the Holders of at least 25.00% in principal amount of the Outstanding Notes issued under this Indenture may declare the principal of, and interest, premium, if any, and any other monetary obligations on, all the Outstanding Notes to be due and payable immediately, by a notice in writing to the Issuer (and to the Trustee if given by Holders).

(b) Upon the effectiveness of a declaration under Section 502(a), such principal, premium, if any, and interest will be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising under Section 501(9) with respect to the Issuer, any Subsidiary of the Issuer that is a Significant Subsidiary or any group of Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary, all Outstanding Notes will become due and payable immediately without further action or notice.

(c) If a Default for a failure to report or failure to deliver a required certification in connection with another Default (the 'InitialDefault') occurs, then at the time such Initial Default is cured, such Default for a failure to report or failure to deliver a required certificate in connection with another Default that resulted solely because of that Initial Default will also be cured without any further action. Any Default for the failure to comply with the provisions under Section 1009 or otherwise to deliver any notice or certificate pursuant to any other provision of this Indenture shall be deemed to be cured upon the delivery of any such report required by Section 1009 or such notice or certificate, as applicable, even though such delivery is not within the prescribed period specified in this Indenture.

(d) Holders of a majority in aggregate principal amount of the Outstanding Notes, by written notice to the Trustee, may (i) at any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, rescind and annul such declaration and its consequences, so long as such rescission and annulment would not conflict with any judgment of a court of competent jurisdiction and all amounts owing to the Trustee have been paid and (ii) waive an existing Default or Event of Default and its consequences hereunder (except a continuing Default in the payment of principal of, or interest or premium, if any, on, any Outstanding Note held by a non-consenting Holder which has become due otherwise than by such declaration of acceleration); provided, however, that no such rescission or waiver shall affect any subsequent default or impair any right consequent thereon.

(e) Notwithstanding the preceding paragraph, in the event of any Event of Default specified in Section 501(6) above, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 20 days after such Event of Default arose,

(1)

the Indebtedness or Guarantee that is the basis for such Event of Default has been discharged, or

(2)

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

(3)

if the default that is the basis for such Event of Default has been cured or is no longer continuing.

-44-

(f) Any notice of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default, notice of acceleration or take any other action (a 'Noteholder Direction') provided by any one or more Holders of Notes (each a 'Directing Holder') must be accompanied by a written representation from each such Holder delivered to the Issuer and the Trustee that such Holder is not (or, in the case such Holder is the Depositary or its nominee, that such Holder is being instructed solely by beneficial owners that have represented to such Holder that they are not) Net Short (a 'Position Representation'), which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default shall be deemed a continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the Notes are accelerated. If the Holder of a Note is a clearing system or a common safekeeper or its nominee, any Position Representation required hereunder shall be provided by the clearing system or the common safekeeper or its nominee or by the beneficial owner of an interest in such Global Note after delivery to the Trustee of appropriate confirmation of beneficial ownership satisfactory to the Trustee. In addition, each Directing Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide the Issuer with such other information as the Issuer may reasonably request from time to time in order to verify the accuracy of such Holder's Position Representation within five Business Days of request therefor (a 'Verification Covenant'). The Trustee shall have no duty whatsoever to obtain this information for the Issuer. In any case in which the Holder of a Note is the Depositary or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Note in lieu of the Depositary or its nominee, and the Depositary shall be entitled to rely conclusively on such Position Representation and Verification Covenant in delivering its direction to the Trustee. If the Trustee acts pursuant to a Noteholder Direction, the Trustee shall, upon written request, deliver copies of the Position Representations for all Directing Holders to the Issuer within three Business Days of such request.

If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Issuer determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officer's Certificate stating that the Issuer has initiated litigation in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Event of Default that resulted from the applicable Noteholder Direction, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to such Event of Default shall be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Issuer provides to the Trustee an Officer's Certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to any Event of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation shall result in such Holder's participation in such Noteholder Direction being disregarded; and, if, without the participation of such Holder, the percentage of Notes held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Event of Default shall be deemed never to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default; provided, however, that any indemnity or security provided by the Directing Holders to the Trustee shall not be invalidated and shall continue to survive. For the avoidance of doubt, the foregoing requirements applicable to Noteholder Directions do not apply to any other directions given by Holders of Notes to the Trustee under this Indenture.

-45-

With its acquisition of a Note, each Holder and subsequent purchaser of the Note consents to the delivery of its Position Representation by the Trustee to the Issuer in accordance with the terms of this Indenture. Each Holder of a Note and subsequent purchaser of the Note waives any and all claims, in law and/or in equity, against the Trustee, and agrees not to commence any legal proceeding against the Trustee in respect of, and agrees that the Trustee will not be liable for any action that the Trustee takes in accordance with this Indenture, or arising out of or in connection with following instructions or taking actions, in each case in accordance with a Noteholder Direction and, in each case, other than arising out of or in respect of the Trustee's gross negligence or willful misconduct. The Issuer hereby waives any and all claims, in law and/or in equity, against the Trustee, and agrees not to commence any legal proceeding against the Trustee in respect of, and agrees that the Trustee will not be liable for any action that the Trustee takes in accordance with this Indenture, or arising out of or in connection with following instructions or taking actions, in each case in accordance with a Noteholder Direction and, in each case, other than arising out of or in respect of the Trustee's gross negligence or willful misconduct.

Notwithstanding anything in this Section 502(f) to the contrary, any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default specified in Section 501(9) above, shall not require compliance with this Section 502(f). For the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with this Indenture, shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements in any Officer's Certificate delivered to it, or otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise. The Trustee shall have no liability to the Issuer, any Holder of a Note or any other Person in acting in good faith in accordance with a Noteholder Direction. For the avoidance of doubt, the Trustee will treat all Holders of Notes equally with respect to their rights under this Indenture. In connection with the requisite percentages required under this Indenture, the Trustee shall also treat all outstanding Notes equally irrespective of any Position Representation in determining whether the requisite percentage has been obtained with respect to the initial delivery of the Noteholder Direction. The Issuer confirms that any and all actions that the Trustee takes or omits to take with respect to a Noteholder Direction, and all fees, costs expenses of the Trustee and its agents and counsel arising in connection therewith, shall be covered by the Issuer's indemnification obligations under Section 607.

SECTION 503. Additional Interest. Notwithstanding anything else in this Indenture or in the Notes, in the event of the Issuer's failure to comply with its obligations under Section 1009: (a) the sole remedy of the Holders and the Trustee after the occurrence of any such failure shall, for the first 180 days following the occurrence of such failure, consist exclusively of the right to receive additional interest ('AdditionalInterest') with respect to the Notes at a rate equal to 0.25% per annum of the principal amount of such Notes, which Additional Interest shall accrue from and including the date on which such failure first occurred to the 180th day thereafter (or such earlier date on which such failure shall have been cured or waived); (b) during such 180 day period, any such failure shall be deemed not to be an Event of Default; and (c) on the 181st day after such failure (if such failure shall not have been cured or waived prior to such 181st day), such failure will then constitute an Event of Default without any further notice or lapse of time and the Notes will be subject to acceleration as provided in Section 502. If Additional Interest is payable on the Notes, the Issuer shall provide an Officer's Certificate to the Trustee on or before the Regular Record Date for each Interest Payment Date such Additional Interest is payable setting forth the accrual period and the amount of such Additional Interest payable. The Trustee may provide a copy of such Officer's Certificate relating to Additional Interest to any Holder upon request. Unless and until a Responsible Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether any Additional Interest is payable, or with respect to the nature, extent, or calculation of the amount of any Additional Interest owed, or with respect to the method employed in such calculation of any Additional Interest. If the Issuer shall have paid Additional Interest directly to the persons entitled to it, the Issuer shall deliver to the Trustee an Officer's Certificate setting forth the particulars of such payment.

-46-

SECTION 504. Collection of Indebtedness and Suits for Enforcement by Trustee. The Issuer covenants that if:

(1)

default is made in the payment of any installment of interest on any Note when such interest becomes due and payable and such default continues for a period of 30 days, or

(2)

default is made in the payment of the principal of or premium, if any, on any Note at the Maturity thereof,

the Issuer will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal of, and interest or premium, if any, on, the Notes when due, and interest or premium, if any, on any overdue principal, and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Issuer fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Issuer, any Guarantor or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Issuer, any Guarantor or any other obligor upon the Notes, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders under this Indenture and the Note Guarantees by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any such rights, including seeking recourse against any Guarantor, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy, including seeking recourse against any Guarantor.

SECTION 505. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Issuer or any other obligor including any Guarantor, upon the Notes or the property of the Issuer or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Issuer for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(1)

to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Notes and to file such 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 of the Holders allowed in such judicial proceeding, and

-47-

(2)

to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors' committee or other similar committee.

SECTION 506. Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

SECTION 507. Application of Money Collected. Any money or property collected by the Trustee pursuant to this Article, or after the occurrence and during the continuance of an Event of Default any money or property distributable in respect of the Issuer's or Guarantors' obligations under this Indenture, shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, interest or premium, if any, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee (including any predecessor Trustee) under Section 607;

SECOND: To the payment of the amounts then due and unpaid for principal of, and interest or premium, if any, on, the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal, and interest or premium, if any, respectively; and

THIRD: The balance, if any, to the Issuer or as a court of competent jurisdiction may direct in writing; provided, however, that all sums due and owing to the Holders and the Trustee have been paid in full as required by this Indenture.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 507.

-48-

SECTION 508. Limitation on Suits. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder of a Note shall pursue any remedy with respect to this Indenture or the Notes, unless:

(1)

such Holder has previously given the Trustee written notice that an Event of Default is continuing;

(2)

Holders of at least 25.00% in aggregate principal amount of the Outstanding Notes have requested in writing the Trustee to pursue the remedy;

(3)

such Holder or Holders have offered and, if requested, provided to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense;

(4)

the Trustee does not comply with such request within 60 days after receipt of the request and the offer of security or indemnity; and

(5)

during such 60-day period, Holders of a majority in aggregate principal amount of the Outstanding Notes do not give the Trustee a direction inconsistent with such request,

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or the Note Guarantees to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture or the Note Guarantees, except in the manner herein provided and for the equal and ratable benefit of all the Holders (it being further 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 509. Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article Eleven) and in such Note of the principal of, and premium, if any, and (subject to Section 307) interest on, such Note on the respective Stated Maturities expressed in such Note (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment on or after such respective dates, and such rights shall not be impaired without the consent of such Holder.

SECTION 510. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture or the Note Guarantees and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuer, any Guarantor, any other obligor of the Notes, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 511. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

-49-

SECTION 512. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 513. Control by Holders. The Holders of not less than a majority in principal amount of the Outstanding Notes shall have the right to 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 with respect to the Notes; provided, however, that:

(1)

such direction shall not be in conflict with any rule of law or with this Indenture, and such Holders have complied with Section 603(6),

(2)

the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

(3)

the Trustee need not take any action which might involve it in personal liability or be unjustly prejudicial to the Holders not consenting (it being further understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unjustly prejudicial to such Holders).

SECTION 514. Waiver of Past Defaults. Subject to Sections 509 and 902, the Holders of not less than a majority in principal amount of the Outstanding Notes by written notice to the Trustee may on behalf of the Holders of all such Notes waive any existing Default or Event of Default and its consequences hereunder (except (1) a continuing Default or Event of Default in the payment of principal of, or interest or premium, if any, on, such Note held by a non-consenting Holder, or (2) in respect of a covenant or provision hereof or in any Note Guarantee which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Note affected, which shall require the consent of all such Holders) and rescind any acceleration and its consequences with respect to the Notes; provided, however, such rescission would not conflict with any judgment of a court of competent jurisdiction.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

SECTION 515. Waiver of Stay or Extension Laws. Each of the Issuer, the Guarantors and any other obligor on the Notes covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and each of the Issuer, the Guarantors and any other obligor on the Notes (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

-50-

Upon request of any such successor Trustee, the Issuer shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

(b) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 611. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder; provided, however, such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee shall have; provided, however, that, the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Any such appointment shall be evidenced by an instrument in writing signed by an authorized signatory of the Trustee, and a copy of such instrument shall be promptly furnished to the Issuer. Wherever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Issuer.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent; provided, however, such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Issuer. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Issuer. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Issuer and shall give written notice of such appointment to all Holders of Notes, in the manner provided for in Section 107. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Issuer agrees to pay to each Authenticating Agent from time to time such compensation for its services under this Section as shall be agreed in writing between the Issuer and such Authenticating Agent.

If an appointment is made pursuant to this Section, the Notes may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternate certificate of authentication in the following form:

ARTICLE TEN

COVENANTS

SECTION 1001. Payment of Principal, Premium, if any, and Interest. The Issuer covenants and agrees for the benefit of the Holders that it will duly and punctually pay the principal of, and premium, if any, and interest on, the Notes in accordance with the terms of the Notes and this Indenture. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Issuer, holds as of 12:00 noon Eastern Time on the due date money deposited by the Issuer in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due.

-63-

SECTION 1002. Maintenance of Office or Agency. The Issuer will maintain in the continental United States an office or agency where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Corporate Trust Office of the Trustee shall be such office or agency of the Issuer in continental United States, unless the Issuer shall designate and maintain some other office or agency for one or more of such purposes. The Issuer will give prompt written notice to the Trustee of any change in the location of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Issuer hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

The Issuer 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; provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency in continental United States. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office or agency.

SECTION 1003. Money for Notes Payments to Be Held in Trust. If the Issuer shall at any time act as its own Paying Agent, it will, on or before each due date of the principal of, or premium, if any, or interest on, any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal, or premium, if any, or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee in writing of its action or failure so to act.

Whenever the Issuer shall have one or more Paying Agents for the Notes, it will, on or before each due date of the principal of, or premium, if any, or interest on, any Notes in accordance with Section 1001, deposit with a Paying Agent a sum sufficient to pay the principal, interest or premium, if any, so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Issuer will promptly notify the Trustee in writing of such action or any failure so to act.

Each Paying Agent agrees:

(1)

that it will hold all sums received by it as Paying Agent for the payment of the principal of or interest on any Notes in trust for the benefit of the Holders or of the Trustee;

(2)

that it will give the Trustee notice of any failure by the Issuer to make any payment of the principal of or interest on any Notes and any other payments to be made by or on behalf of the Issuer under this Indenture or the Notes when the same shall be due and payable; and

(3)

that it will pay any such sums so held in trust by it to the Trustee forthwith upon the Trustee's written request at any time during the continuance of the failure referred to in clause (2) above.

-64-

The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Issuer Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Issuer or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Issuer or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, or premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Issuer on Issuer Request, or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as Trustee thereof, shall thereupon cease.

SECTION 1004. Organizational Existence. Subject to Article Eight, the Issuer will do or cause to be done all things necessary to preserve and keep in full force and effect its organizational existence and its organizational rights (charter and statutory) and franchises; provided, however, that the Issuer shall not be required to preserve any such right or franchise if the Board of Directors of the Issuer shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Subsidiaries, taken as a whole.

SECTION 1009. Reports and Other Information.

(a) Notwithstanding that the Issuer may not be required to be or remain subject to the reporting requirements of Section 13(a) or 15(d) of the Exchange Act, the Issuer will file with the SEC (unless such filing is not permitted under the Exchange Act or by the SEC), so long as any Notes are Outstanding, the annual reports, information, documents and other reports that the Issuer is required to file with the SEC pursuant to such Section 13(a) or 15(d) or would be so required to file if the Issuer were so subject.

-65-

(b) Notwithstanding the foregoing, the Issuer will not be obligated to file such reports with the SEC if the SEC does not permit such filing; provided, however, in such case, the Issuer shall provide such information to the Trustee and the Holders, prospective investors that certify they are qualified institutional buyers, securities analysts and market makers ('Permitted Parties') by the date the Issuer would be required to file such information pursuant to the preceding paragraph. The requirements set forth in this paragraph and the preceding paragraph may be satisfied by delivering such information electronically to the Trustee and posting copies of such information on a website (which may be nonpublic and may be maintained by the Issuer or a third party) to which Permitted Parties are given access and to which such information is posted.

(c) For so long as the Issuer is subject to the reporting requirements of Section 13(a) or 15(d) of the Exchange Act, the Issuer shall use its commercially reasonable efforts, consistent with its judgment as to what is prudent at the time, to participate in quarterly and annual conference calls to discuss results of operations with Permitted Parties. The Issuer shall issue a press release which will provide the date and time of any such call and will direct Permitted Parties to contact the investor relations office of the Issuer to obtain access to the conference call.

(d) At any time when the Issuer is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Issuer shall use its reasonable efforts to participate in quarterly and annual private conference calls to discuss results of operations with Permitted Parties within 15 Business Days after the date on which quarterly and annual, as the case may be, reports are required to be furnished under this Indenture. The Issuer shall employ commercially reasonably means expected to reach Permitted Parties no fewer than three Business Days prior to the date of the conference call required to be held to announce the time and date of such conference call and either including all information necessary to access the call or directing Permitted Parties to contact the appropriate person at the Issuer to obtain such information.

(e) At any time when the Issuer is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Issuer will furnish to Holders and to prospective investors, upon the requests of such Holders, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are 'restricted securities' under Rule 144 under the Securities Act.

(f) Notwithstanding anything else contained in this Indenture, if the Issuer has filed with the SEC the reports described in the preceding paragraphs (including via the EDGAR system or any successor electronic filing system), the Issuer shall be deemed to be in compliance with clauses (a), (b) and (e) above.

(g) Delivery of reports, information and documents to the Trustee is for informational purposes only and its receipt of such reports shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer's compliance with any of its covenants under this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officer's Certificates). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, our compliance with the covenants or with respect to any reports or other documents filed with the SEC or EDGAR or website under this Indenture, or participate in any conference calls.

The Issuer shall not, and shall not permit any of its Subsidiaries to, create, incur or assume any Lien (other than Permitted Liens) upon any Principal Property to secure Indebtedness of the Issuer, any Subsidiary of the Issuer or any other Person, without securing the Notes equally and ratably with or, at the option of the Issuer, prior to, such other Indebtedness for so long as such other Indebtedness is so secured. Any Lien that is granted to secure the Notes under this Section 1010 shall be automatically released and discharged at the same time as the release of the Lien that gave rise to the obligation to secure the Notes under this Section 1010. The foregoing restriction shall not apply to any Subsidiary that constitutes an Excluded Subsidiary for so long as it constitutes an Excluded Subsidiary.

SECTION 1011. Limitation on Subsidiary Debt.

(b) Any such Subsidiary also may, without Guaranteeing the payment of the principal of, or premium, if any, or interest on, the Notes, extend, renew, replace, refinance or refund any Subsidiary Debt permitted pursuant to Section 1011(a); provided that any Subsidiary Debt incurred to so extend, renew, replace, refinance or refund shall be incurred within 360 days of the maturity, retirement or other repayment or prepayment of the Subsidiary Debt being extended, renewed, replaced, refinanced or refunded and the principal amount of the Subsidiary Debt incurred to so extend, renew, replace, refinance or refund shall not exceed the principal amount of Subsidiary Debt being extended, renewed, replaced, refinanced or refunded plus any premium or fee (including tender premiums) or other reasonable amounts payable, plus the amount of fees, expenses and other costs incurred, in connection with any such extension, renewal, replacement, refinancing or refunding.

(c) For purposes of determining compliance with this Section 1011, (i) any other obligation of the obligor on such Indebtedness (or of any other Person who could have incurred such Indebtedness under this Section 1011 under clauses (a)(1) through (a)(12) above) arising under any Guarantee, Lien or letter of credit, bankers' acceptance or other similar instrument or obligation supporting such Indebtedness shall be disregarded to the extent that such Guarantee, Lien or letter of credit, bankers' acceptance or other similar instrument or obligation secures the principal amount of such Indebtedness; (ii) in the event that an item of Indebtedness meets the criteria of more than one of the categories of Subsidiary Debt described in clauses (a)(1) through (a)(12) above, the Issuer will be permitted to classify such item of Indebtedness on the date of its incurrence, and such item of Indebtedness will be treated as having been incurred pursuant to only one of such categories; and (iii) the accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, will not be deemed to be an incurrence of Indebtedness for purposes of this Section 1011.

(d) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, where the Indebtedness incurred is denominated in a different currency, the amount of such Indebtedness will be the U.S. dollar equivalent determined on the date of the incurrence of such Indebtedness; provided, however, that if any such Indebtedness denominated in a different currency is subject to a currency agreement with respect to U.S. dollars covering all principal, premium, if any, or interest payable on such Indebtedness, the amount of such Indebtedness expressed in U.S. dollars will be as provided in such currency agreement. The principal amount of any refinancing Indebtedness incurred in the same currency as the Indebtedness being

-69-

refinanced will be the U.S. dollar equivalent of the Indebtedness being refinanced, except to the extent that (1) such U.S. dollar equivalent was determined based on a currency agreement, in which case the refinancing Indebtedness will be determined in accordance with the preceding sentence, and (2) the principal amount of the refinancing Indebtedness exceeds the principal amount of the Indebtedness being refinanced, in which case the U.S. dollar equivalent of such excess will be determined on the date such refinancing Indebtedness is incurred. The maximum amount of Indebtedness that any Subsidiary of the Issuer may incur pursuant to this Section 1011 shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in exchange rates or currency values.

(e) The amount of any Indebtedness outstanding as of any date will be:

(1)

the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2)

the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(3)

in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(A)

the fair market value of such assets at the date of determination; and

(B)

the amount of the Indebtedness of the other Person.

SECTION 1012. Limitation on Sale and Leaseback Transactions.

(a) The Issuer will not, nor will it permit any of its Subsidiaries to, enter into any arrangement with any other Person pursuant to which the Issuer or any of its Subsidiaries leases any Principal Property that has been or is to be sold or transferred by the Issuer or the Subsidiary to such other Person (a 'Sale and Leaseback Transaction').

(b) The following Sale and Leaseback Transactions are not subject to the limitation above or the restrictions set forth in Section 1010:

(1)

temporary leases for a term, including renewals at the option of the lessee, of not more than three years;

(2)

leases between only the Issuer and a Subsidiary of the Issuer or only between Subsidiaries of the Issuer or leases with an Excluded Subsidiary for so long as it constitutes an Excluded Subsidiary;

(3)

leases where the proceeds from the sale of the subject property are at least equal to the fair market value (as determined in good faith by the Issuer) of the subject property and the Issuer applies an amount equal to the net proceeds of the sale to the retirement of long term Indebtedness or the purchase, construction, development, expansion or improvement of other property or equipment used or useful in its business, within 270 days of the closing date of such sale; provided that in lieu of applying such amount to the retirement of long-term Indebtedness, the Issuer may deliver Notes to the Trustee or other debt securities to the trustee of such long-term Indebtedness for cancellation; and

-70-

(4)

leases of property executed by the time of, or within 270 days after the latest of, the acquisition, the completion of construction, development, expansion or improvement, or the commencement of commercial operation, of the subject property.

(c) Notwithstanding the foregoing, the Issuer and its Subsidiaries may enter into any Sale and Leaseback Transaction that would otherwise be subject to the restrictions set forth in the first paragraph above, if after giving effect thereto and at the date of determination, Aggregate Net Availability Debt does not exceed the greatest of (a) $1,000.0 million, (b) 15% of the Consolidated Net Tangible Assets of the Issuer measured as of the closing date of such Sale and Leaseback Transaction and (c) 3.75 times EBITDA of the Issuer for the Applicable Measurement Period.

SECTION 1013. Change of Control Repurchase Event.

(a) If a Change of Control Repurchase Event occurs, unless the Issuer at such time has given notice of redemption pursuant to Article Four or Eleven with respect to all the Outstanding Notes and all conditions to such redemption have been either satisfied or waived, each Holder will have the right to require the Issuer to repurchase all or any part (in a principal amount equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder's Notes pursuant to an offer to repurchase on the terms described below (the 'Change ofControl Offer'). In the Change of Control Offer, the Issuer will offer a price in cash (the 'Change of Control Payment') equal to 101.00% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including the date of purchase, subject to the rights of Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Payment Date. Within 30 days following any Change of Control Repurchase Event, unless the Issuer at such time has given notice of redemption pursuant to Article Four or Eleven with respect to all of the Outstanding Notes, the Issuer will mail by first class mail or overnight mail, with a copy to the Trustee sent in the same manner, to each Holder (such mailing to be sent to the address of such Holder appearing in the Note Register or otherwise delivered in accordance with the procedures of the Depositary) and to the Trustee describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed or otherwise sent (the 'Change of Control Payment Date'), and such notice shall include the following information:

(1)

that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest on the Change of Control Payment Date;

(2)

if such notice is delivered prior to the occurrence of a Change of Control Repurchase Event, stating that the Change of Control Offer is conditional on the occurrence of such Change of Control Repurchase Event and if applicable, shall state that, in the Issuer's discretion, the Change of Control Payment Date may be delayed until such time as the Change of Control Repurchase Event shall occur, or that such redemption may not occur and such notice may be rescinded in the event that the Issuer shall determine that such condition will not be satisfied by the Change of Control Payment Date, or by the Change of Control Payment Date as so delayed; and

(3)

the other instructions, as determined by the Issuer, consistent with this Section 1013, that a Holder must follow.

-71-

(b) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 1013, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 1013 by virtue of such compliance, and the foregoing procedures will be deemed modified as necessary to permit such compliance.

(c) On the Change of Control Payment Date, the Issuer shall, to the extent lawful,

(1)

accept for payment all Notes or portions of Notes (in a principal amount equal to $2,000 or an integral multiple of $1,000 in excess thereof) properly tendered and not withdrawn pursuant to the Change of Control Offer,

(2)

deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered and not withdrawn and

(3)

deliver, or cause to be delivered, to the Trustee the Notes properly accepted together with an Officer's Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

(d) In the event that the Issuer makes a Change of Control Payment, the Paying Agent shall promptly mail or deliver to each Holder of Notes properly tendered and not withdrawn the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount equal to $2,000 or an integral multiple of $1,000 in excess thereof. The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(e) The Issuer shall not be required to make a Change of Control Offer following a Change of Control Repurchase Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all such Notes properly tendered and not withdrawn under such Change of Control Offer, or (2) a notice of redemption has been given pursuant to Article Four or Article Eleven at any time prior to 30 days following any Change of Control Repurchase Event with respect to all outstanding Notes, unless and until there is a Default in the payment of the applicable redemption price.

SECTION 1103. Election to Redeem; Notice to Trustee. If the Issuer elects to redeem some or all of the Notes pursuant to Section 1101, it shall furnish to the Trustee, at or prior to the date notice of such redemption is required to be given to Holders, an Officer's Certificate stating (i) the clause of Section 1101 of this Indenture pursuant to which the redemption shall occur, (ii) the Redemption Date, (iii) the principal amount of Notes to be redeemed, (iv) the Redemption Price (or manner of calculation if not then known), (v) that such election has been duly authorized by all requisite corporate action on the part of the Issuer, and (vi) that such redemption complies, or will comply, with any applicable covenants or conditions precedent set forth in this Indenture. Notice of redemption of Notes to be redeemed at the election of the Issuer shall be given to the Trustee by the Issuer or, at the Issuer's request and provision of the notice to be given containing such notice information five Business Days (unless a shorter notice shall be agreed to by the Trustee) prior to the date notice is to be given to the Holders, by the Trustee in the name and at the expense of the Issuer. Any redemption may be cancelled by the Issuer upon written notice to the Trustee at any time prior to notice of redemption being sent to any Holder and thereafter shall be null and void. If the Redemption Price is not known at the time such notice is to be given, the actual Redemption Price, calculated as described in the terms of the Notes, will be set forth in an Officer's Certificate delivered to the Trustee no later than two Business Days prior to the Redemption Date.

SECTION 1104. Selection by Trustee of Notes to Be Redeemed. If less than all of the Notes are to be redeemed at any time, the Trustee will select the Notes for redemption on a pro rata basis (or, in the case of Notes issued in global form, subject to the applicable procedures of the Depositary) unless otherwise required by law or applicable stock exchange or depositary requirements.

Notes with a principal amount of $2,000 or less cannot be redeemed in part. Notices of redemption shall be delivered by first class mail (or otherwise in accordance with the procedures of the Depositary), at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such Holder's registered address, except that redemption notices may be mailed or sent more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. If any Note is to redeemed in part only, any notice of redemption that relates to such Note shall state the portion of the principal amount thereof that has been or is to be redeemed.

If any Notes are to be redeemed in part only, the Issuer shall issue a new Note (or cause to be transferred by book entry) in principal amount equal to the unredeemed portion of the original Note in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption, subject to the satisfaction of any applicable conditions. On and after the Redemption Date, unless the Issuer defaults in payment of the Redemption Price, interest shall cease to accrue on Notes or portions of Notes called for redemption (unless the Issuer defaults in the payment of the applicable redemption payment).

SECTION 1105. Notice of Redemption. Notice of redemption shall be given in the manner provided for in Section 107 not less than 10 nor more than 60 days prior to the Redemption Date, to each Holder to be redeemed.

All notices of redemption shall identify the Notes and state:

(3)

if less than all Outstanding Notes are to be redeemed, the identification (and, in the case of a partial redemption, the principal amounts) of the particular Notes to be redeemed,

(4)

in case any Note is to be redeemed in part only, the notice which relates to such Note shall state that on and after the Redemption Date, upon surrender of such Note, the Holder will receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof remaining unredeemed,

(5)

that on the Redemption Date the Redemption Price (and accrued interest, if any, to the Redemption Date payable as provided in Section 1107) will become due and payable upon each such Note, or the portion thereof, to be redeemed, and that, if the redemption occurs, interest thereon will cease to accrue on and after said date,

(6)

any condition precedent to the redemption;

(7)

the place or places where such Notes are to be surrendered for payment of the Redemption Price and accrued interest, if any,

(8)

(9)

that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price,

(10)

the CUSIP, ISIN or 'Common Code' number and that no representation is made as to the accuracy or correctness of the CUSIP, ISIN or 'Common Code' number, if any, listed in such notice or printed on the Notes, and

(11)

the clause of Section 1101 and/or the paragraph of the Notes pursuant to which the Notes are to be redeemed.

Any redemption may, at the Issuer's discretion, be subject to one or more conditions precedent, which shall be set forth in the related notice of redemption, including, but not limited to, completion of an Equity Offering, other offering or other transaction or event. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Issuer's discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed.

If any such condition precedent has not been satisfied, the Issuer shall provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date (or such shorter period as may be acceptable to the Trustee). Upon receipt of such notice, the notice of redemption shall be rescinded or delayed, and the redemption of the Notes shall be rescinded or delayed as provided in such notice. Upon receipt, the Trustee shall provide such notice to each Holder in the same manner in which the notice of redemption was given.

The Issuer or its Affiliates may acquire Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, so long as such acquisition does not otherwise violate the terms of this Indenture.

-75-

SECTION 1106. Deposit of Redemption Price. No later than 12:00 noon (New York City time) on any Redemption Date, the Issuer shall deposit with the Trustee or with a Paying Agent (or, if the Issuer is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and accrued interest on, all the Notes which are to be redeemed on that date.

SECTION 1107. Notes Payable on Redemption Date. Notice of redemption having been given to the Holders in accordance with Section 1105, the Notes so to be redeemed shall, on the Redemption Date, become due and payable, unless such redemption is conditioned on the happening of a future event, at the Redemption Price therein specified (together with accrued interest to the Redemption Date), and from and after such date (unless the Issuer shall default in the payment of the Redemption Price and accrued interest) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, the Redemption Price for such Note , together with accrued interest to the Redemption Date, shall be paid by the Issuer and such Notes shall be canceled by the Trustee; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the close of business on the relevant Regular Record Dates according to their terms and the provisions of Section 307.

If the Redemption Price for any Note called for redemption, together with accrued interest to the Redemption Date, shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Notes, unless such redemption is conditioned on the happening of a future event.

SECTION 1108. Notes Redeemed in Part. Any Note which is to be redeemed only in part (pursuant to the provisions of this Article) shall be surrendered at an office or agency of the Issuer maintained for such purpose pursuant to Section 1002 (with, if the Issuer or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the Holder thereof or such Holder's attorney duly authorized in writing), and the Issuer shall execute, and the Trustee shall authenticate and deliver (or transfer by book entry) to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered.

ARTICLE TWELVE

GUARANTEES

SECTION 1201. Note Guarantees. Subject to this Article Twelve, each Guarantor hereby jointly and severally, fully and unconditionally Guarantees, on a senior basis, the Notes and Obligations of the Issuer hereunder and thereunder, and Guarantees to each Holder of a Note authenticated and delivered by the Trustee, and to the Trustee for itself and on behalf of such Holder, that: (1) the principal of, and interest and premium, if any, on, the Notes will be paid in full when due, whether at Stated Maturity, by acceleration or otherwise (including the amount that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Law), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder will be paid in full or performed, all in accordance with the terms hereof and thereof; and (2) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise, subject, however, in the case of clauses (1) and (2) above, to the limitation set forth in Section 1204 hereof.

-76-

Each Guarantor hereby agrees (to the extent permitted by applicable law) that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

Each Guarantor hereby waives (to the extent permitted by law) the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer or any other Person, protest, notice and all demands whatsoever and covenants that the Note Guarantee of such Guarantor shall not be discharged as to any Note except by complete performance of the obligations contained in such Note, this Indenture and such Note Guarantee. Each Guarantor acknowledges that the Note Guarantee is a Guarantee of payment, performance and compliance when due and not of collection. Each of the Guarantors hereby agrees that, in the event of a default in payment of principal, interest or premium, if any, with respect to such Note, whether at its Stated Maturity, by acceleration, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce such Guarantor's Note Guarantee without first proceeding against the Issuer or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the Maturity of the Notes, to collect interest on the Notes or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holder the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Note Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee on the other hand, (1) subject to this Article Twelve, the Maturity of the obligations Guaranteed hereby may be accelerated as provided in Article Five hereof for the purposes of the Note Guarantee of such Guarantor notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations Guaranteed hereby, and (2) in the event of any acceleration of such obligation as provided in Article Five hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Note Guarantee of such Guarantor.

Each Note Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuer for liquidation, reorganization, should the Issuer become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuer's assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes, whether as a 'voidable preference', 'fraudulent transfer' or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

-77-

SECTION 1202. Severability. In case any provision of any Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby to the extent permitted by applicable law.

SECTION 1203. Additional Guarantors. The Issuer shall cause any Subsidiary required to Guarantee payment of the Notes pursuant to the terms and provisions of Section 1011 to execute and deliver to the Trustee any amendment pursuant to Section 901(7) or supplement to this Indenture (in the case of such supplement, substantially in the form of Exhibit A) in accordance with the provisions of Article Nine of this Indenture pursuant to which such Subsidiary shall Guarantee all of the obligations on the Notes, whether for principal, premium, if any, interest (including interest accruing after the filing of, or which would have accrued but for the filing of, a petition by or against the Issuer under any Bankruptcy Law, whether or not such interest is allowed as a claim after such filing in any proceeding under such law) and other amounts due in connection therewith (including any fees, expenses and indemnities), on an unsecured senior basis. Upon the execution of any such amendment or supplement, the obligations of the Guarantors and any such Subsidiary under their respective Note Guarantees shall become joint and several and each reference to the 'Guarantor' in this Indenture shall, subject to Section 1208, be deemed to refer to all Guarantors, including such Subsidiary. Such Note Guarantee shall be released in accordance with Section 802 and Section 1208.

SECTION 1204. Limitation of Guarantors' Liability. Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the Guarantee by each such Guarantor pursuant to its Note Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Holders and each such Guarantor hereby irrevocably agree that the obligations of such Guarantor under its Note Guarantee shall be limited to the maximum amount that will not, 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 this Section 1204, result in the obligations of such Guarantor under its Note Guarantee constituting such fraudulent transfer or conveyance.

SECTION 1205. Contribution. In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, interse, that in the event any payment or distribution is made by any Guarantor (a 'Funding Guarantor') under a Note Guarantee, such Funding Guarantor shall be entitled to a contribution from all other Guarantors in a prorataamount based on the Adjusted Net Assets (as defined below) of each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Issuer's obligations with respect to the Notes or any other Guarantor's obligations with respect to the Note Guarantee of such Guarantor. 'AdjustedNetAssets' of such Guarantor at any date shall mean the lesser of (1) the amount by which the fair value of the property of such Guarantor exceeds the total amount of liabilities, including contingent liabilities (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date), but excluding liabilities under the Note Guarantee of such Guarantor at such date and (2) the amount by which the present fair salable value of the assets of such Guarantor at such date exceeds the amount that will be required to pay the probable liability of such Guarantor on its debts (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date), excluding debt in respect of the Note Guarantee of such Guarantor, as they become absolute and matured.

-78-

SECTION 1206. Subrogation. Each Guarantor shall be subrogated to all rights of Holders against the Issuer in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 1201; provided, however, that, if an Event of Default has occurred and is continuing, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuer under this Indenture or the Notes shall have been paid in full.

SECTION 1207. Reinstatement. Each Guarantor hereby agrees (and each Person who becomes a Guarantor shall agree) that the Note Guarantee provided for in Section 1201 shall continue to be effective or be reinstated, as the case may be, if at any time, payment, or any part thereof, of any obligations or interest thereon is rescinded or must otherwise be restored by a Holder to the Issuer upon the bankruptcy or insolvency of the Issuer or any Guarantor.

SECTION 1208. Release of a Guarantor. Any Note Guarantee by a Guarantor of the Notes shall be automatically and unconditionally released and discharged upon:

(1)

in connection with any sale or other disposition of all or substantially all of the assets of such Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Subsidiary of the Issuer;

(2)

in connection with any sale or other disposition of Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Subsidiary of the Issuer, if the Guarantor ceases to be a Subsidiary of the Issuer as a result of the sale or other disposition;

(3)

upon the merger or consolidation of such Guarantor with or into the Issuer or another Guarantor that is the surviving Person in such merger or consolidation, or upon the liquidation of such Guarantor following the transfer of all of its assets to the Issuer or another Guarantor;

(4)

the exercise of the Legal Defeasance of the Notes under Section 1302 hereof, or the Covenant Defeasance of the Notes under Section 1303 hereof, or if the Issuer's obligations under this Indenture are discharged in accordance with Section 401 of this Indenture;

(5)

in the case of a Guarantor that becomes an Excluded Subsidiary, upon delivery to the Trustee of an Officer's Certificate certifying that such Guarantor has become an Excluded Subsidiary; or

(6)

upon the release or discharge of the Guarantee by such Subsidiary of such Indebtedness of the Issuer or any Subsidiary, or the repayment of all the Indebtedness, in each case, that resulted in an obligation to provide a Note Guarantee (including, the release, discharge or repayment of all outstanding amounts under the Term Loan Facility, the Revolving Facility and the 2028 Notes with respect to any Guarantor that provided a Note Guarantee as of the Issue Date).

-79-

SECTION 1209. Benefits Acknowledged. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and from its Guarantee and waivers pursuant to its Note Guarantees under this Article Twelve.

SECTION 1210. Effectiveness of Note Guarantees.

This Indenture and the Note Guarantees shall be effective upon its execution and delivery by the parties hereto. Each Guarantor hereby agrees that its Note Guarantee pursuant to this Article Twelve shall be effective notwithstanding the absence of an endorsement of any notation of such Note Guarantee on the Notes.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301. Issuer's Option to Effect Legal Defeasance or Covenant Defeasance.

SECTION 1302. Legal Defeasance and Discharge. Upon the Issuer's exercise under Section 1301 of the option applicable to this Section 1302, the Issuer and each of the Guarantors shall be deemed to have been discharged from their respective obligations with respect to all Outstanding Notes, the Note Guarantees and this Indenture on the date the conditions set forth in Section 1304 are satisfied (hereinafter, 'Legal Defeasance'). For this purpose, such Legal Defeasance means that the Issuer and each of the Guarantors shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Notes (including the Note Guarantees), which shall thereafter be deemed to be 'Outstanding' only for the purposes of Section 1305 and the other Sections of this Indenture referred to in (1) and (2) below, and to have satisfied all its other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of Outstanding Notes to receive payments in respect of the principal of, and interest or premium, if any, on, such Notes when such payments are due, from the trust described in Section 1305, (2) the Issuer's obligations with respect to such Notes under Sections 303, 304, 305, 306, 1002 and 1003 and (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder, and the obligations of each of the Guarantors and the Issuer in connection therewith. Subject to compliance with this Section 1302, the Issuer may exercise its option under this Section 1302 notwithstanding the prior exercise of its option under Section 1303 with respect to the Notes.

SECTION 1303. Covenant Defeasance. Upon the Issuer's exercise under Section 1301 of the option applicable to this Section 1303, each of the Issuer and the Guarantors shall be released from its respective obligations under Sections 801 and 1004 and Sections 1009 through and including 1013 with respect to the Outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, 'Covenant Defeasance'), and the Notes shall thereafter be deemed not to be 'Outstanding' for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed 'Outstanding' for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Notes, the Issuer or any Guarantor, as applicable, 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

-80-

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 Event of Default under Section 501, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby.

SECTION 1304. Conditions to Legal Defeasance or Covenant Defeasance. The following shall be the conditions to application of either Section 1302 or Section 1303 to the Outstanding Notes:

Before such a deposit, the Issuer may give to the Trustee, in accordance with Section 1103 hereof, a notice of its election to redeem all of the Outstanding Notes at a future date in accordance with Article Eleven hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing;

(2)

in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the Trustee confirming that,

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

(B) since the Issue Date, 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 shall confirm that, subject to customary assumptions and exclusions, the Holders of the Outstanding Notes will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

-81-

(3)

in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the Trustee confirming that, the Holders of the Outstanding Notes will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4)

no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit (and any similar and concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

(5)

such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which, the Issuer or any of its Subsidiaries is a party or by which any of them is bound;

(6)

the Issuer shall have delivered to the Trustee an Officer's Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders over the other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or others; and

(7)

the Issuer shall have delivered to the Trustee an Officer's Certificate and an Opinion of Counsel each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with.

SECTION 1305. Deposited Money and Government Securities To Be Held in Trust Other Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 1003, all cash and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1305, the 'QualifyingTrustee') pursuant to Section 1304 in respect of the Outstanding Notes shall be held in trust and applied by the Qualifying Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Qualifying Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, interest and premium, if any, but such money or Government Securities need not be segregated from other funds except to the extent required by law.

The Issuer shall pay and indemnify the Qualifying Trustee against any tax, fee or other charge imposed on or assessed against the Government Securities deposited pursuant to Section 1304 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Notes.

Anything in this Article Thirteen to the contrary notwithstanding, the Qualifying Trustee shall deliver or pay to the Issuer from time to time upon Issuer Request any money or Government Securities held by it as provided in Section 1304 which are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance, as applicable, in accordance with this Article; provided that, solely in a case involving Government Securities, such determination shall be accompanied by an opinion of an investment bank, appraisal firm or firm of

SECTION 1306. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or Government Securities in accordance with Section 1305 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer's and each Guarantor's obligations under this Indenture and the Outstanding Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 1302 or 1303, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 1305; provided, however, that, if the Issuer makes any payment of principal of, or interest or premium, if any, on, any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

Beneficial interests in a Rule 144A Global Note may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Note, whether before or after the expiration of the Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form provided in this Indenture) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if applicable).

The Rule 144A Global Note and the Regulation S Global Note are collectively referred to herein as 'Global Notes'. The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary as hereinafter provided.

-2-

(b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Note deposited with or on behalf of the Depositary.

The Issuer shall execute and the Trustee shall, in accordance with this Section 2.1(b), authenticate and deliver initially one or more Global Notes that (a) shall be registered in the name of the Depositary and (b) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary's instructions or held by the Trustee as custodian for the Depositary.

Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair as between the Depositary and its Agent Members, the operation of customary practices of the Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Note.

Such order shall specify the amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated.

2.3 Transfer and Exchange.

(a) Transfer and Exchange of Definitive Notes. When Definitive Notes are presented to the Note Registrar with a request:

(x) to register the transfer of such Definitive Notes; or

-3-

(y) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations, the Note Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Notes surrendered for transfer or exchange:

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

(ii) if such Definitive Notes are required to bear a restricted notes legend, they are being transferred or exchanged pursuant to an effective registration statement under the Securities Act, pursuant to Section 2.3(b) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

(A) if such Definitive Notes are being delivered to the Note Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or

(B) if such Definitive Notes are being transferred to the Issuer, a certification to that effect; or

(C) if such Definitive Notes are being transferred (x) pursuant to an exemption from registration in accordance with Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of the Securities Act: (i) a certification to that effect (in the form set forth on the reverse of the Note) and (ii) if the Issuer so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.3(d)(i).

(b) Restrictions on Transfer of a Definitive Note for a Beneficial Interest in a Global Note. A Definitive Note may not be exchanged for a beneficial interest in a Rule 144A Global Note or a Regulation S Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with:

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

(ii) written instructions directing the Trustee to make, or to direct the Notes Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Note (in the case of a transfer pursuant to clause (b)(i)(A)) or Regulation S Global Note (in the case of a transfer pursuant to clause (b)(i)(B)) to reflect an increase in the aggregate principal amount of the Notes represented by the Rule 144A Global Note or Regulation S Global Note, as applicable, such instructions to contain information regarding the Agent Member account to be credited with such increase,

then the Trustee shall cancel such Definitive Note and cause, or direct the Notes Custodian to cause, in accordance with the standing instructions and procedures of the Depositary and the Notes Custodian, the aggregate principal amount of Notes represented by the Rule 144A Global Note or Regulation S Global Note, as applicable, to be increased by the aggregate principal amount of the Definitive Note to be

-4-

exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Note or Regulation S Global Note, as applicable, equal to the principal amount of the Definitive Note so canceled. If no Rule 144A Global Notes or Regulation S Global Notes, as applicable, are then outstanding, the Issuer shall issue and the Trustee shall authenticate, upon written order of the Issuer in the form of an Officer's Certificate of the Issuer, a new Rule 144A Global Note or Regulation S Global Note, as applicable, in the appropriate principal amount.

(c) Transfer and Exchange of Global Notes.

(i) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Note shall deliver to the Note Registrar a written order given in accordance with the Depositary's procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the Global Note. The Note Registrar shall, in accordance with such instructions instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being transferred.

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

(iii) Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor depositary or a nominee of such successor depositary.

(iv) In the event that a Global Note is exchanged for a Definitive Note pursuant to Section 2.4 of this Appendix, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Notes intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Issuer.

(v) During the Distribution Compliance Period, beneficial ownership interests in Regulation S Global Notes may only be sold, pledged or transferred in accordance with the Applicable Procedures and only (i) to the Issuer, (ii) in an offshore transaction in accordance with Regulation S (other than a transaction resulting in an exchange for an interest in a Regulation S Global Note) or (iii) pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities laws of any State of the United States.

(vi) In the event that a Global Note is exchanged for Definitive Notes pursuant to Section 2.4, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Notes intended to ensure that such transfers comply with Rule 144A, Regulation S or such other applicable exemption from registration under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Issuer.

-5-

(vii) Upon the Issuer's satisfaction that the Notes are no longer Transfer Restricted Notes and the legends in Section 2.3(e) below shall no longer be required in order to maintain compliance with the Securities Act, beneficial interests in a Transfer Restricted Note that is a Global Note may, at the Issuer's option, be automatically exchanged into beneficial interests in a Global Note that is not a Transfer Restricted 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 (A) with respect to the Initial Notes issued on the Issue Date, the Issue Date or (B) 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 Issuer's satisfaction that the Notes are no longer Transfer Restricted Notes and the legend in Section 2.3(d) below shall no longer be required in order to maintain compliance with the Securities Act, the Issuer may (i) provide written notice to the Trustee at least 10 calendar days prior to any Automatic Exchange, instructing the Trustee to direct the Depositary to exchange all of the outstanding beneficial interests in a particular Transfer Restricted Note that is a Global Note to a Global Note that is not a Transfer Restricted Note, which the Issuer shall have previously otherwise made eligible for exchange with the Depositary, (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 10 calendar days prior to any Automatic Exchange (an '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 Transfer Restricted Note from which such Holder's beneficial interests will be transferred and (z) the 'CUSIP' number of the Global Note that is not a Transfer Restricted Note into which such Holder's beneficial interests will be transferred, and (iii) on or prior to the date of the Automatic Exchange, deliver to the Trustee for authentication one or more Global Notes that are not Transfer Restricted Notes, duly executed by the Issuer, in an aggregate principal amount equal to the aggregate principal amount of Transfer Restricted Notes to be exchanged. At the Issuer's request on no less than five calendar days' notice, the Trustee shall deliver, in the Issuer's name and at its expense, the Automatic Exchange Notice to each Holder at such Holder's address appearing in the register of Holders. Notwithstanding anything to the contrary in this Section 2.3(c)(vii), during the 10 day period between the Automatic Exchange Notice Date and the Automatic Exchange Date, no transfers or exchanges other than pursuant to this Section 2.3(c)(vii) shall be permitted without the prior written consent of the Issuer. As a condition to any Automatic Exchange, the Issuer shall provide, and the Trustee shall be entitled to rely upon, an Officer's Certificate reasonably acceptable to the Trustee to the effect that such Automatic Exchange shall be effected in compliance with the Securities Act and that the restrictions on transfer contained herein and in the legends in Section 2.3(d) below shall no longer be required in order to maintain compliance with the Securities Act, and that the aggregate principal amount of the particular Global Notes that are Transfer Restricted Notes may be transferred to the particular Global Notes that are note Transfer Restricted Notes by adjustment made on the records of the Trustee, as the depositary custodian, to reflect such Automatic Exchange. Upon such exchange of beneficial interests pursuant to this Section 2.3(c)(vii), the aggregate principal amount of the Global Notes shall be increased or decreased by adjustments made on the records of the Trustee, as depositary custodian, to reflect the relevant increase or decrease in the principal amount of such Global Note resulting from the applicable exchange. The Transfer Restricted Note from which beneficial interests are transferred pursuant to an Automatic Exchange shall be canceled following such Automatic Exchange.

(d) Legend.

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

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE 'SECURITIES ACT'), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF, AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED SECURITIES, TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE 'RESALE RESTRICTION TERMINATION DATE') THAT IS [IN THE CASE OF RULE 144A NOTES: ONE YEAR AFTER THE LATEST OF THE ORIGINAL ISSUE DATE HEREOF, THE ORIGINAL ISSUE DATE OF THE ISSUANCE OF ANY ADDITIONAL NOTES AND THE LAST DATE ON WHICH THE ISSUER OR ANY AFFILIATE OF THE ISSUER WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF SUCH SECURITY),] [IN THE CASE OF REGULATION S NOTES: 40 DAYS AFTER THE LATEST OF THE ORIGINAL ISSUE DATE HEREOF, THE ORIGINAL ISSUE DATE OF THE ISSUANCE OF ANY ADDITIONAL NOTES AND THE DATE ON WHICH THIS SECURITY (OR ANY PREDECESSOR OF SUCH SECURITY) WAS FIRST OFFERED TO PERSONS OTHER THAN DISTRIBUTORS (AS DEFINED IN RULE 902 OF REGULATION S) IN RELIANCE ON REGULATION S], ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT ('RULE 144A'), TO A PERSON IT REASONABLY BELIEVES IS A 'QUALIFIED INSTITUTIONAL BUYER' AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT, (E) TO AN INSTITUTIONAL 'ACCREDITED INVESTOR' WITHIN THE MEANING OF RULE 501(a)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT THAT IS NOT A QUALIFIED INSTITUTIONAL BUYER AND THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF ANOTHER INSTITUTIONAL ACCREDITED INVESTOR, IN EACH CASE IN A MINIMUM PRINCIPAL AMOUNT OF $250,000 OF SECURITIES OR (F) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY'S AND THE TRUSTEE'S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSES (D), (E) OR (F) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. A SECURITY NOT BEARING THIS LEGEND WILL BE ISSUED AFTER THE RESALE RESTRICTION TERMINATION DATE IN ACCORDANCE WITH APPLICABLE PROCEDURES OF THE DEPOSITORY TRUST COMPANY, OR IF THE SECURITIES ARE NOT GLOBAL SECURITIES, UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. [IN THE CASE OF REGULATION S NOTES: BY ITS ACQUISITION HEREOF, THE HOLDER HEREOF REPRESENTS THAT IT IS NOT A U.S. PERSON NOR IS IT PURCHASING FOR THE ACCOUNT OF A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT.]

-7-

BY ITS ACQUISITION OF THIS SECURITY, THE HOLDER THEREOF WILL BE DEEMED TO HAVE REPRESENTED AND WARRANTED THAT EITHER (1) NO PORTION OF THE ASSETS USED BY SUCH HOLDER TO ACQUIRE OR HOLD THIS SECURITY CONSTITUTES THE ASSETS OF AN EMPLOYEE BENEFIT PLAN THAT IS SUBJECT TO TITLE I OF THE U.S. EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED ('ERISA'), OF A PLAN, INDIVIDUAL RETIREMENT ACCOUNT OR OTHER ARRANGEMENT THAT IS SUBJECT TO SECTION 4975 OF THE U.S. INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE 'CODE') OR PROVISIONS UNDER ANY OTHER FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER LAWS OR REGULATIONS THAT ARE SIMILAR TO SUCH PROVISIONS OF ERISA OR THE CODE ('SIMILAR LAWS'), OR OF AN ENTITY WHOSE UNDERLYING ASSETS ARE CONSIDERED TO INCLUDE 'PLAN ASSETS' OF ANY SUCH PLAN, ACCOUNT OR ARRANGEMENT, OR (2) THE ACQUISITION AND HOLDING OF THIS SECURITY WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE OR A SIMILAR VIOLATION UNDER ANY APPLICABLE SIMILAR LAWS.

Each Definitive Note shall also bear the following additional legend:

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

(ii) Upon any sale or transfer of a Transfer Restricted Note (including any Transfer Restricted Note represented by a Global Note) pursuant to Rule 144 under the Securities Act, the Note Registrar shall permit the transferee thereof to exchange such Transfer Restricted Note for a certificated Note that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Note, if the transferor thereof certifies in writing to the Note Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Note).

(iii) After a transfer of any Initial Notes during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Notes, all requirements pertaining to the restricted notes legend on such Initial Securities shall cease to apply and the requirements that any such Initial Notes be issued in global form shall continue to apply.

(e) Cancellation or Adjustment of Global Note. At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Notes, redeemed, purchased or canceled, such Global Note shall be returned to the Depositary for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes, redeemed, purchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes Custodian, to reflect such reduction.

-8-

(f) No Obligation of the Trustee.

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners. Neither the Trustee nor any Agent shall have responsibility for any actions taken or not taken by the Depositary.

(ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among the Depositary participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Principal and Interest.

The Issuer will pay the principal of this Note on May 1, 2029.

The Issuer promises to pay interest on the principal amount of this Note on each Interest Payment Date, as set forth below, at the rate of 3.625% per annum.

Interest will be payable semi-annually (to the Holders of record of the Notes (or any Predecessor Notes) at the close of business on October 15 or April 15 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing November 1, 2021.

Interest on this Note will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from April 30, 2021; provided, however, that, if there is no existing Default in the payment of interest and if this Note is authenticated between a Regular Record Date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

The Issuer shall pay interest on overdue principal and premium, if any, and interest on overdue installments of interest, to the extent lawful, at a rate per annum equal to the rate of interest applicable to the Notes.

2.

Method of Payment.

The Issuer will pay interest (except Defaulted Interest) on the principal amount of the Notes on each November 1 and May 1 (commencing on November 1, 2021) to the Persons who are Holders (as reflected in the Note Register at the close of business on October 15 and April 15 immediately preceding the Interest Payment Date), in each case, even if the Note is cancelled on registration of transfer or registration of exchange after such Regular Record Date; provided, however, that, with respect to the payment of principal, the Issuer will make payment to the Holder that surrenders this Note to any Paying Agent on or after May 1, 2029.

The Issuer will pay principal, interest and premium, if any in U.S. dollars.

However, the Issuer may pay principal, interest or premium, if any, by its check payable in such money; provided, that all payments of principal, premium, if any, and interest with respect to Notes represented by one or more permanent Global Notes registered in the name of or held by the Depositary will be made by wire transfer of immediately available funds to the Depositary; provided, further, that all payments of principal, premium, if any, and interest with respect to certificated Notes will be made by wire transfer of immediately available funds to any Holder of such Notes in certificate form in immediately available funds to accounts specified by the holders of such certificate notes at least ten days in advance of the applicable payment date. Subject to the foregoing sentence, the Issuer may make payments on the Notes by mailing a check for such interest to a Holder's registered address (as reflected in the Note Register). If a payment date is a date other than a Business Day at a place of payment, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period.

If a bankruptcy or insolvency Default with respect to the Issuer occurs and is continuing, the Notes automatically become immediately due and payable. Subject to the provisions of the Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any rights or powers under the Indenture at the request or direction of any of the Holders of the Notes unless such Holders have offered indemnity or security against any loss, liability or expense satisfactory to the Trustee. Subject to certain restrictions, the Holders of a majority in principal amount of the outstanding Notes are given the right to 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. The Trustee, however, may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee in personal liability.

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

2. We understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is one year after the later of the date of original issue and the last date on which the Issuer or any affiliate of the Issuer was the owner of such Notes (or any predecessor thereto) (the 'Resale Restriction Termination Date') only (i) to the Issuer, (ii) pursuant to a registration statement that has been declared effective under the Securities Act, (iii) in a transaction complying with the requirements of Rule 144A under the Securities Act ('Rule 144A'), to a person we reasonably believe

The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to clause (v) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the 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 prior to the Resale Restriction Termination Date of the Notes pursuant to clause (iv), (v) or (vi) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Issuer and the Trustee.
