Any reference in this Indenture to a merger, transfer, consolidation, amalgamation, consolidation, assignment, sale, disposition or transfer, or similar term, shall be deemed to apply to a division of or by a limited liability company, a limited partnership or any other entity, or an allocation of assets to a series of a limited liability company, a limited partnership or any other entity (or the unwinding of such a division or allocation), as if it were a merger, transfer, consolidation, amalgamation, consolidation, assignment, sale, disposition or transfer, or similar term, as applicable, to, of or with a separate Person.

Section 1.04    Limited Condition Transactions and Other Compliance Measurements. Notwithstanding anything to the contrary in this Indenture (including in connection with any calculation that is made on a pro forma basis), in connection with any action being taken in connection with a Limited Condition Transaction, for purposes of:

(a)    determining compliance with any provision of this Indenture which (i) requires the calculation of any financial ratio or test (including the Consolidated Net Total Leverage Ratio, Consolidated Senior Secured Debt Ratio and Fixed Charge Coverage Ratio) and/or (ii) requires the absence of any Default or Event of Default (or any type of Default or Event of Default); or

(b)    determining compliance with any basket or other condition set forth in this Indenture (including baskets measured as a percentage of Consolidated EBITDA or Consolidated Total Assets);

in each case, at the option of the Company (the Company’s election to exercise such option in connection with any Limited Condition Transaction, an “LCT Election”), the date of determination of whether any such action is permitted under this Indenture shall be deemed to be (A) in the case of any acquisition or other Investment in an Unrestricted Subsidiary (including by way of merger, amalgamation or consolidation) or any assumption or Incurrence of Liens, or any transaction relating thereto, the date (or on the basis of the financial statements for the most recently ended reference period) of entry into a binding letter of intent or the definitive agreements for such Limited Condition Transaction (or, solely in connection with an acquisition (including by way of merger, amalgamation or consolidation); or (B) in the case of any other Restricted Payment, at the time (or on the basis of the financial statements for the most recently ended reference period) of the declaration of such Restricted Payment (the applicable date determined pursuant to clause (A) or (B), the “LCT Test Date”), and if, after giving effect to the Limited Condition Transaction and the other transactions to be entered into in connection therewith (including any Incurrence of Indebtedness and the use of proceeds thereof) and, at the election of the Company, any other Limited Condition Transaction that has not been consummated but with respect to which the Company has made an LCT Election, on a pro forma basis as if they had occurred at the beginning of the most recently completed reference period ending prior to the LCT Test Date, the Company or the applicable Restricted Subsidiary would have been permitted to take such action on the relevant LCT Test Date in compliance with such ratio,

-25-

test, basket or condition, such ratio, test, basket or condition shall be deemed to have been complied with. For the avoidance of doubt, if the Company has made an LCT Election and any of the ratios, tests, baskets or conditions for which compliance was determined or tested as of the LCT Test Date are exceeded as a result of fluctuations in any such ratio, test, basket or condition, including due to fluctuations in Consolidated EBITDA at or prior to the consummation of the relevant transaction or action, such baskets, tests, ratios and conditions will not be deemed to have been exceeded as a result of such fluctuations.

In addition, for purposes of determining the permissibility of any action, change, transaction or event that requires a calculation of any financial ratio or financial test and/or the amount of Consolidated Total Assets or Adjusted Consolidated Net Income, such financial ratio, financial test or amount shall, subject to the immediately preceding paragraph, be calculated at the time such action is taken, such change is made, such transaction is consummated or such event occurs, as the case may be, and no Default or Event of Default shall be deemed to have occurred solely as a result of a change in such financial ratio, financial test or amount occurring after the time such action is taken, such change is made, such transaction is consummated or such event occurs, as the case may be.

Notwithstanding anything to the contrary in this Indenture, unless the Company otherwise notifies the Trustee, with respect to any amount Incurred or transaction entered into (or consummated) in reliance on a provision of this Indenture that does not require compliance with a financial ratio or financial test (any such amount, including any amount drawn under any revolving credit facility and any cap expressed as a percentage of Adjusted Consolidated Net Income or Consolidated Total Assets, a “Fixed Amount”) substantially concurrently with any amount Incurred or transaction entered into (or consummated) in reliance on a provision of this Indenture that requires compliance with a financial ratio or financial test (any such amount, an “Incurrence-Based Amount”), it is understood and agreed that (i) the Incurrence of the Incurrence-Based Amount shall be calculated first without giving effect to any Fixed Amount but giving full pro forma effect to the use of proceeds of such Fixed Amount and the related transactions and (ii) the Incurrence of the Fixed Amount shall be calculated thereafter. Unless the Company elects otherwise, the Company shall be deemed to have used amounts under an Incurrence-Based Amount then available to the Company prior to utilization of any amount under a Fixed Amount then available to the Company.

Subject to the preceding paragraphs under this caption, all financial ratios and tests and the amount of Adjusted Consolidated Net Income and Consolidated Total Assets contained in this Indenture that are calculated with respect to any reference period shall be calculated with respect to such reference period on a pro forma basis.

For purposes of covenant compliance, the amount of any Investment shall be the amount actually invested, without adjustment for subsequent increases or decreases in the value of such Investment but giving effect to any returns or distributions of capital or repayment of principal actually received in cash by such Person with respect thereto.

Section 1.05    Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Note, shall be sufficient for any purpose of this Indenture and (subject to Section 7.01 hereof) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 1.05.

-26-

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute proof of the authority of the Person executing the same. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient.

(c) The ownership of Notes shall be proved by the register of the Notes maintained by the Registrar.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by 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 any action taken, suffered or omitted by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Note.

(e) The Company may set a record date for purposes of determining the identity of Holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or take any other act, or to vote or consent to any action by vote or consent authorized or permitted to be given or taken by Holders. Unless otherwise specified, if not set by the Company prior to the first solicitation of a Holder made by any Person in respect of any such action, or in the case of any such vote, prior to such vote, any such record date shall be the later of 10 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation.

(f) Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this Section 1.05(f) shall have the same effect as if given or taken by separate Holders of each such different part.

(g) Without limiting the generality of the foregoing, a Holder, including DTC, may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders, and DTC may provide its proxy to the beneficial owners of interests in any such Global Note through such depositary’s standing instructions and customary practices.

The Company may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any Global Note held by DTC entitled under the procedures of such depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action shall be valid or effective if made, given or taken more than 90 days after such record date.

THE NOTES

Section 2.01    Form and Dating.

(a)    General. The Notes shall be designated as the “4.50% Senior Notes due 2028.” The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is initially limited to $600.0 million, except for Notes authenticated and delivered upon registration or transfer of or in exchange for or in lieu of other Notes pursuant to Sections 2.06 and 2.07 hereof. Additional Notes may be issued from time to time after the Closing Date in accordance with Section 2.14 hereof. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. Unless a Note shall have a zero dollar balance, the Notes shall be in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company, the Subsidiary 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.

(b)    Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

Section 2.02    Execution and Authentication. At least one Officer must sign the Notes for the Company by manual, facsimile or electronic signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

A Note will not be valid until authenticated by the manual or electronic signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee will, upon receipt of a written order of the Company signed by two Officers of the Company (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. Each Authentication Order shall specify the number of separate Note certificates to be authenticated, and the registered Holder, principal amount and delivery direction for each Note. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 of this Indenture.

-28-

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication of the Notes 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 Company.

Section 2.03    Registrar and Paying Agent. The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Company and the Trustee; provided, however, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.07 hereof.

The Company initially appoints DTC to act as Depositary with respect to the Global Notes.

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

Section 2.04    Paying Agent to Hold Money in Trust. The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and shall notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

Section 2.05    Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Company shall furnish, or request that the Registrar furnish, to the Trustee at least seven (7) Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes.

(c)    Transfer and Exchange of Beneficial Interests for Definitive Notes. If any holder of a beneficial interest in an Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 2.06(b)(2) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.06(g) hereof, and the Company will execute and the Trustee will authenticate upon receipt of an Authentication Order in accordance with Section 2.02 hereof and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.06(c) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee shall deliver such Definitive Notes to the Persons in whose names such Notes are so registered.

(d)    Transfer and Exchange of Definitive Notes for Beneficial Interests. A Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.

(A)    to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection;

(B)    to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(C)    to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date.

(6)    Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

(7)    The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof.

(8)    All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile or electronic mail.

(9)    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 Notes (including any transfers between or among Participants) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.07    Replacement Notes. If any mutilated Note is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements for replacements of Notes are met. The Holder must supply indemnity or security sufficient in the judgment of the Trustee (with respect to the Trustee) and the Company (with respect to the Company) to protect the Company, the Trustee, any Agent or any authenticating agent from any loss which any of them may suffer if a Note is replaced. The Company and the Trustee may charge for their fees and expenses in replacing a Note including amounts to cover any tax, assessment, fee or other governmental charge that may be imposed in relation thereto. The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes.

Every replacement Note is an obligation of the Company.

Section 2.08    Outstanding Notes. The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07 hereof.

If a Note is replaced pursuant to Section 2.07 of this Indenture, it ceases to be outstanding unless the Trustee and the Registrar receive proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay all principal, premium and accrued interest with respect to the outstanding Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09    Treasury Notes. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, request, waiver or consent in the exercise of any discretion, power or authority (whether contained in this Indenture or vested by operation of law) which the Trustee is required, expressly or impliedly, to exercise in or by reference to the interests of the Holders or any of them, Notes owned by the Company or any Subsidiary Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee knows are so owned will be so disregarded.

Section 2.10    Temporary Notes. Until Definitive Notes are ready for delivery, the Company may prepare and the Trustee shall upon receipt of an Authentication Order authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate Definitive Notes in exchange for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as Definitive Notes.

-34-

Section 2.11    Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of all canceled Notes in its customary manner (subject to the record retention requirements of the Exchange Act and the Trustee), and upon the written request of the Company, the Trustee shall deliver evidence of such cancellation to the Company. The Company may not issue new Notes to replace Notes that it has redeemed or paid or that have been delivered to the Trustee for cancellation.

Section 2.12    Payment of Interest; Defaulted Interest. Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 2.03; provided, however, that each installment of interest, if any, on any Note may at the Company’s option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 2.05, to the address of such Person as it appears on the Note or (ii) transfer to an account maintained by the payee located inside the United States.

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 registered Holder thereof on the relevant regular Record Date by virtue of having been such Holder, and such defaulted interest and, if applicable, interest on such defaulted interest (to the extent lawful) at the rate or formula specified in the Notes (such defaulted interest and, if applicable, interest thereon herein collectively called “Defaulted Interest”) may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall not be less than 20 days after such notice is received by the Trustee), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or 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 Trustee 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 Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice (which notice shall be prepared by the Company) of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Notes at his address as it appears in the Registrar 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 mailed as aforesaid, 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).

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

-35-

Subject to the foregoing provisions of this Section and Section 2.06, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

Section 2.13    CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” and/or “ISIN” numbers (if then generally in use). The Trustee shall not be responsible for the use of CUSIP or ISIN numbers, and the Trustee makes no representation as to their correctness as printed on any Note or notice to Holders. The Company shall promptly notify the Trustee in writing of any change in the CUSIP or ISIN numbers. A separate CUSIP or ISIN number will be issued for any Additional Notes, unless the Initial Notes and such Additional Notes are treated as “fungible” for U.S. federal income tax purposes.

Section 2.14    Issuance of Additional Notes. The Company may issue Additional Notes under this Indenture in accordance with the procedures of Section 2.02. The Initial Notes issued on the date of this Indenture and any Additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture; provided that any Additional Notes that are not fungible with the Notes for U.S. federal income tax purposes will have a separate CUSIP, ISIN, common code or other identifying number, as applicable.

Section 2.15    Record Date. The Record Date for purposes of determining the identity of Holders entitled to vote or consent to any action by vote or consent authorized or permitted under this Indenture shall be determined as specified by the Company to the Trustee.

(2)    the redemption date;

(3)    the principal amount of Notes to be redeemed;

(4)    the redemption price;

(5)    applicable CUSIP numbers; and

Section 3.02    Selection of Notes to Be Redeemed. If less than all of the Notes are to be redeemed at any time, the Trustee shall select Notes for redemption or purchase as follows:

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

-36-

(2)    if the Notes are not listed on any national securities exchange, by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate.

In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 10 days nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $2,000 or integral multiples of $1,000 in excess thereof; provided that no Notes of $2,000 in principal amount or less shall be redeemed in part. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03    Notice of Redemption. At least 10 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to the Trustee and each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12 hereof.

The notice shall identify the Notes (including CUSIP numbers) to be redeemed and will state:

(1)    the redemption date;

(2)    the redemption price;

(3)    if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note or with respect to a Global Note a notation shall be made on Schedule A thereto to reduce the principal amount of the Global Note to an amount equal to the unredeemed portion of the Global Note surrendered;

(4)    the name and address of the Paying Agent;

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

(6)    that, unless the Company defaults in making such redemption payment, interest on Notes (or portion thereof) called for redemption ceases to accrue on and after the redemption date;

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

(8)    whether the redemption of the Notes is subject to one or more conditions precedent; and

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

-37-

In addition, any notice given with respect to a redemption pursuant to Section 3.07 may provide that payment of the redemption price and performance of the Company’s obligations with respect to any redemption or purchase may be performed by another Person. At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at their expense; provided, however, that the Company has delivered to the Trustee, at least 10 days (or such shorter period as shall be acceptable to the Trustee) prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in this Section 3.03.

Any notice of redemption may, at the Company’s discretion, state that it is subject to one or more conditions precedent, including, but not limited to, completion of any debt or equity offering, Change of Control or other corporate transaction or event. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’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 so delayed.

Section 3.04    Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption shall, subject to the provisions of the final paragraph of Section 3.03, become irrevocably due and payable on the redemption date at the redemption price.

Section 3.05    Deposit of Redemption Price. Prior to 11:00 a.m., New York City time, on the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest, if any, on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest, if any, on, all Notes to be redeemed.

If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest will cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption is not so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06    Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

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

If an Event of Default specified in Section 6.01(g) or (h) above occurs with respect to the Company, the principal of, premium, if any, and accrued interest on the Notes then outstanding shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

(b)    [reserved].

(c)    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 (each a “Directing Holder”) must be accompanied by a written representation from each such Holder (other than a Regulated Bank) delivered to the Company and the Trustee that such Holder is not (or, in the case such Holder is DTC or its nominee, that such Holder is being instructed solely by beneficial owners that 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. In addition, each Directing Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide the Company with such other information as the Company 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”). In any case in which the Holder is DTC or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Notes in lieu of DTC or its nominee and DTC shall be entitled to conclusively rely on such Position Representation and Verification Covenant in delivering its direction to the Trustee.

If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Company 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 Officers’ Certificate stating that the Company has initiated litigation with 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 Company provides to the Trustee an Officers’ 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;

-53-

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, any acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Event of Default.

Notwithstanding anything in this Section 6.02(c) to the contrary, any Noteholder Direction delivered to the Trustee in connection with a Default under Sections 6.01(d), (e) or (f) during the pendency of an Event of Default under Section 6.01(g) as a result of a bankruptcy or similar proceeding shall not require compliance with this Section 6.02(c). In addition, for the avoidance of doubt, this Section 6.02(c) shall not apply to any Holder that is a Regulated Bank.

Section 6.03    Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

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

Section 6.04    Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the outstanding Notes by written notice to the Company and to the Trustee may waive all past defaults and rescind and annul a declaration of acceleration and its consequences if (x) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and accrued interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived and (y) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. The Company shall deliver to the Trustee an Officers’ Certificate stating that the requisite percentage of Holders have consented to such waiver and attaching copies of such consents. When a Default or Event of Default is waived, it is cured and ceases.

Section 6.05    Control by Majority. The Holders of at least a majority in aggregate principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal expense or liability for which (as determined in good faith by it) the Trustee has not received adequate indemnity, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from Holders of Notes. Prior to taking any action under the Indenture at the direction of Holders, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

Section 6.06    Limitation on Suits.

(a)    A Holder may not pursue any remedy with respect to this Indenture or the Notes unless:

(1)    the Holder gives the Trustee written notice of a continuing Event of Default;

-54-

(2)    the Holders of at least 30% in aggregate principal amount of outstanding Notes make a written request to the Trustee to pursue the remedy;

(3)    such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against any costs, liability or expense;

(4)    the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5)    during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request.

Section 6.07    Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, and interest on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08    Collection Suit by Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in clause (a) or (b) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any other obligor on the Notes for the whole amount of principal, premium, if any, and accrued interest and fees remaining unpaid, together with interest on overdue principal and premium, if any, and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum borne by the Notes and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 7.06 of this Indenture.

Section 6.09    Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 7.06 of this Indenture) and the Holders allowed in any judicial proceedings relating to the Company, its creditors or its property and shall be entitled and empowered to participate as a member, voting or otherwise, of any official committee appointed for such matter, to collect and receive any monies or other securities or property payable or deliverable upon the conversion or exchange of the Notes or upon any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee under Section 7.06 of this Indenture. 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.

Section 6.10    Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

First: to the Trustee for amounts due under Section 7.06 of this Indenture;

-55-

Second: to Holders for interest accrued on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for interest;

Third: to Holders for principal amounts and premium, if any, due and unpaid on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal; and

Fourth: to the Company or, if applicable, the Subsidiary Guarantors as their respective interests may appear.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to each Holder and the Company a notice that states the record date, the payment date and amount to be paid.

Section 6.11    Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable and documented attorneys’ fees and expenses against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

Section 6.12    Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture 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 proceedings, the Company, 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 has been instituted.

Section 6.13    Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07 hereof, 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.

Section 6.14    Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder 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 6 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.

ARTICLE 7

TRUSTEE

Section 7.01    Duties of Trustee.

(a)    If an Event of Default has occurred and is continuing, the Trustee shall, in the exercise of its rights and powers under this Indenture, use the same degree of care and skill in its exercise of such rights and powers as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs, subject to the provisions of clause (h) below.

(b)    Except during the continuance of an Event of Default of which a Trust Officer has actual knowledge, the Trustee and the Agents:

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

(ii)    in the absence of willful misconduct or gross negligence on its part, may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee under this Indenture, the Notes and the Note Guarantees, as applicable. However, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture, the Notes and the Note Guarantees as the case may be (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(c)    The Trustee and the Agents shall not be relieved from liability for their own negligent action, their own negligent failure to act or their own willful misconduct, except that:

(i)    this Section 7.01(c) does not limit the effect of Section 7.01(b);

(ii)    the Trustee and the Agents shall not be liable for any error of judgment made in good faith by a Trust Officer or Trust Officers unless it is proved in a final non-appealable decision of a court of competent jurisdiction that the Trustee and the Agents were negligent in ascertaining the pertinent facts; and

(iii)    the Trustee and the Agents shall not be liable with respect to any action they take or omit to take in good faith in accordance with a direction received by it pursuant to Section 6.05.

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

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

-57-

(g)    Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee and the Agents shall be subject to the provisions of this Section 7.01.

(h)    The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee, security, prefunding or indemnity satisfactory to it against the costs, expenses (including reasonable attorneys’ fees and expenses), losses and liabilities that might be incurred by it in compliance with such request or direction.

(i)    The Agents shall have the right to become Holders as freely as if they were not a party to this Indenture.

(j)    The Agents shall act solely as agents of the Company and need not act in the best interests of the Holders.

(k)    The obligations of the Agents under this Indenture shall be several and not joint.

Section 7.02    Rights of Trustee.

(a)    The Trustee and the Agents may conclusively rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond or any other paper or document believed by it to be genuine and to have been signed or presented by the proper Person or Persons. The Trustee and the Agents need not investigate any fact or matter stated in the document.

(b)    Before the Trustee or an Agent acts or refrains from acting (except in connection with (x) the issuance of the Initial Notes on the Closing Date and (y) with respect to an Opinion of Counsel, the execution of any amendment or supplement adding a new Guarantor under this Indenture), it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee or an Agent shall not be liable for any action it takes or omits to take in good faith in reliance on an Officers’ Certificate or Opinion of Counsel.

(c)    The Trustee may act through its attorneys, custodians, nominees and agents and shall not be responsible for the misconduct or negligence of or for the supervision of any agent, custodians, nominees or attorney appointed with due care.

(d)    Neither the Trustee nor an Agent shall be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee’s or such Agent’s conduct does not constitute willful misconduct or negligence as determined in a final non-appealable decision of a court of competent jurisdiction.

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

(f)    The Trustee and the Agents shall not be bound to make any investigation into any statement, warranty or representation, or the facts or matters stated in any resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond or other paper or document made or in connection with this Indenture; moreover, the Trustee and the Agents shall not be bound to make any investigation into (i) the performance or observance of any of the covenants, agreements or other terms or

-58-

conditions set forth herein, (ii) the occurrence of any default, or the validity, enforceability, effectiveness or genuineness of this Indenture or any other agreement, instrument or document or (iii) the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note or other evidence of indebtedness or other paper or document, but the Trustee or an Agent, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee or an Agent, as applicable, shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(g)    The Trustee shall not be deemed to have knowledge of any Default or Event of Default except any Default or Event of Default of which a Responsible Officer shall have received written notification from the Company or a Holder at the Corporate Trust Office of the Trustee and such notice references the Notes and this Indenture.

(h)    In no event shall the Trustee or an Agent be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee or Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

(i)    The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent (including the Agents), custodian and other Person employed to act hereunder.

(j)    The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

(k)    The Trustee shall not have any duty (A) to see to any recording, filing, or depositing of this Indenture or any agreement referred to herein, or to see to the maintenance of any such recording or filing or depositing or to any rerecording, re-filing or redepositing of any thereof or (B) to see to any insurance.

(l)    The right of the Trustee or an Agent to perform any discretionary act enumerated in this Indenture shall not be construed as a duty.

(m)    The Trustee shall furnish the Company periodic cash transaction statements which include detail for all investment transactions effected by the Trustee or brokers selected by the Company. Upon the Company’s election, such statements will be delivered via the Trustee’s online service and upon electing such service, paper statements will be provided only upon request. The Company waives the right to receive brokerage confirmations of security transactions effected by the Trustee as they occur, to the extent permitted by law. The Company further understands that trade confirmations for securities transactions effected by the Trustee will be available upon request and at no additional cost, and other trade confirmations may be obtained from the applicable broker.

Section 7.03    Individual Rights of Trustee. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company, the Guarantors or their Affiliates with the same rights it would have if it were not the Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Section 7.09. In addition, the Trustee shall be permitted to engage in transactions with the Company; provided, however, that if the Trustee acquires any conflicting interest the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the SEC for permission to continue acting as Trustee or (iii) resign.

-59-

Section 7.04    Disclaimer. Neither the Trustee nor any Agent shall be responsible for and none of them makes any representation as to the validity or adequacy of this Indenture, the Notes or the Note Guarantees, neither of them shall be accountable for the Company’s use of the Notes or the proceeds from the Notes, and neither of them shall be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication or for the use or application of any funds received by any Paying Agent other than the Trustee.

Section 7.05    Notice of Defaults. If a Default occurs and is continuing and is actually known to a Responsible Officer of the Trustee, the Trustee shall deliver to each Holder notice of the Default within 90 days after it is known to the Trustee. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Note, the Trustee may withhold notice if and so long as the Trustee in good faith determines that withholding notice is in the interests of the Holders.

Section 7.06    Compensation and Indemnity. The Company shall pay to the Trustee and the Agents from time to time such compensation for their services as the parties shall agree in writing from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee and the Agents upon request for all reasonable out-of-pocket expenses incurred or made by it, including, but not limited to, costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Holders and reasonable costs of counsel, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee or any predecessor Trustee in each of its capacities hereunder (including as Paying Agent, Registrar or as an Agent, as applicable), and each of their officers, directors, employees, counsel and agents, against any and all loss, liability or expense (including, but not limited to, reasonable attorneys’ fees and expenses) incurred by it in connection with the administration of this trust and the performance of their duties hereunder and under the Notes and the Note Guarantees, including the costs and expenses of enforcing this Indenture (including this Section 7.06), the Notes and the Note Guarantees and of defending itself against any claims (whether asserted by any Holder, the Company or otherwise). The Trustee and the Agents shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee or an Agent to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee and the Agents may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee or an Agent as a result of its own willful misconduct or gross negligence.

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Notes. The right of the Trustee to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company.

The Company’s obligations pursuant to this Section and any lien arising hereunder shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee or an Agent. When the Trustee or an Agent incurs expenses after the occurrence of a Default specified in Sections 6.01(g) or (h) with respect to the Company, the expenses are intended to constitute administrative expenses under any Bankruptcy Law.

-60-

Pursuant to Section 11.01, the obligations of the Company hereunder are jointly and severally guaranteed by the Guarantors.

Section 7.07    Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Notes may remove the Trustee by so notifying the Company and the Trustee in writing and may appoint a successor Trustee. The Company shall remove the Trustee if:

(i)    the Trustee fails to comply with Section 7.09;

(ii)    the Trustee is adjudged bankrupt or insolvent;

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

(iv)    the Trustee otherwise becomes incapable of acting.

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

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.06. All costs reasonably incurred in connection with any resignation or removal hereunder shall be borne by the Company.

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

If the Trustee fails to comply with Section 7.09, unless the Trustee’s duty to resign is stayed, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section 7.07, the Company’s obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

Section 7.08    Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have.

-61-

Section 7.09    Eligibility; Disqualification. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. The Trustee together with its affiliates shall at all times have a combined capital surplus of at least $50.0 million as set forth in its most recent annual report of condition. The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties under this Indenture.

Section 7.10    Limitation on Duty of Trustee. The Trustee shall not have any duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture, the Notes and the Note Guarantees by the Company, the Guarantors or any other Person.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01    Legal Defeasance and Covenant Defeasance.

(a)    The Company may at any time, at the option of its Boards of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either clause (b) or (c) below applied to all outstanding Notes upon compliance with the conditions set forth in Section 8.02.

(b)    Upon the Company’s exercise under clause (a) hereof of the option applicable to this paragraph (b), the Company and any Subsidiary Guarantor shall, subject to the satisfaction of the conditions set forth in Section 8.02, be deemed to have been discharged from their respective obligations with respect to all outstanding Notes and the corresponding Subsidiary Guarantees, if any, on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.03 and the other Sections of this Indenture referred to in sub-clauses (i) and (ii) in this paragraph, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions, which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.03, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (ii) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith and (iv) this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this paragraph (b) notwithstanding the prior exercise of its option under paragraph (c) hereof.

(c)    Upon the Company’s exercise under paragraph (a) hereof of the option applicable to this clause (c), the Company and each Subsidiary Guarantor, if any, shall, subject to the satisfaction of the conditions set forth in Section 8.02, be released from their obligations, if any, under the covenants contained in Sections 4.06 and 4.11 and Section 5.01(a)(3) with respect to the outstanding Notes and the corresponding Subsidiary Guarantee, if any, on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any

thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01(d), but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under paragraph (a) hereof of the option applicable to this paragraph (c), subject to the satisfaction of the conditions set forth in Section 8.03 hereof, Section 6.01(c) shall not constitute an Event of Default with respect to Section 5.01(a)(3), Section 6.01(d) shall not constitute an Event of Default with respect to any other covenants or agreements in this Indenture or the Notes and Sections 6.01(e) and 6.01(f) shall not constitute Events of Default.

Section 8.02    Conditions to Legal Defeasance or Covenant Defeasance. The following shall be the conditions to the application of either Section 8.01(b) or 8.01(c) to the outstanding Notes:

In order to exercise either Legal Defeasance or Covenant Defeasance:

(A)    the Company has deposited with the Trustee, in trust, money and/or U.S. Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to pay the principal of, premium, if any, and accrued interest on the Notes on the Stated Maturity of such payments in accordance with the terms of this Indenture and the Notes;

(B)    the Company has delivered to the Trustee an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions, qualifications and exclusions) to the effect that, as a result of the Company’s exercise of its option under Section 8.01(b) to effect a Legal Defeasance or under Section 8.01(c) to effect a Covenant Defeasance, the Holders will not recognize income, gain or loss for federal income tax purposes and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred, which Opinion of Counsel, in the case of a Legal Defeasance, must be based upon either (i) a statute that is enacted, a Treasury regulation that is promulgated and becomes effective or a revenue ruling that is published, after, in each case, the Closing Date or (ii) a private letter ruling directed to the Trustee received from the Internal Revenue Service, which, in the case of each authority described in clause (i) or (ii), provides that in circumstances comparable to a Legal Defeasance no tax consequences will arise for the Holders as a result of the Legal Defeasance;

(C)    immediately after giving effect to such deposit on a pro forma basis, no Event of Default, or event that after the giving of notice or lapse of time or both would become an Event of Default, shall have occurred and be continuing on the date of such deposit, and such deposit shall not result in a breach or violation of, or constitute a default under, any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; and

(D)    the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or any Subsidiary Guarantors or others.

-63-

Section 8.03    Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. The Trustee or Paying Agent shall hold in trust all money or U.S. Government Obligations deposited with it pursuant to this Article 8, and shall apply the deposited money and U.S. Government Obligations in accordance with this Indenture to the payment of principal of, premium, if any, and interest on the Notes.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the money or U.S. Government Obligations deposited pursuant to Section 8.02 hereof or the principal, premium, if any, and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company’s request any money or U.S. Government Obligations held by it as provided in Section 8.02 which, in the opinion of a nationally recognized firm of certified public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.04    Repayment to the Company. The Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal, premium, if any, or interest that remains unclaimed for two years; provided that the Trustee or such Paying Agent, before being required to make any payment, may at the expense of the Company cause to be published once in a newspaper of general circulation in The City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein which shall be at least 30 days from the date of such publication or mailing any unclaimed balance of such money then remaining shall be repaid to the Company. After payment to the Company, Holders entitled to such money must look to the Company for payment as general creditors unless an applicable law designates another Person.

Section 8.05    Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided that if the Company has made any payment of interest on, premium, if any, or principal of any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01    Without Consent of Holders of Notes. Notwithstanding Section 9.02 of this Indenture, the Company, the Subsidiary Guarantors and the Trustee, together, may amend or supplement this Indenture, the Notes and any Note Guarantee without notice to or consent of any Holder to:

(1)    cure any ambiguity, defect, mistake or inconsistency in this Indenture;

(2)    comply with the provisions of Section 5.01 hereof;

-64-

(3)    provide for the succession of any parties to this Indenture (and other amendments that are administrative or ministerial in nature);

(4)    evidence and provide for the acceptance of appointment by a successor Trustee;

(5)    add or release a Subsidiary Guarantor in accordance with the terms of this Indenture;

(6)    to conform the text of this Indenture, the Notes or any Note Guarantee to any provision of the “Description of Notes” set forth in the Offering Memorandum to the extent such provision was intended to be a verbatim recitation thereof; or

(7)    make any change that does not adversely affect the rights of any Holder in any material respect or that would provide any additional rights or benefits to the Holders.

provided that the Company or Subsidiary Guarantor has delivered to the Trustee an Opinion of Counsel and an Officers’ Certificate, each stating that such amendment or supplement complies with the provisions of this Section 9.01.

Section 9.02    With Consent of Holders of Notes. Subject to Section 6.07, the Company, the Subsidiary Guarantors, and the Trustee, together, with the written consent of the Holder or Holders of not less than a majority in aggregate principal amount of the outstanding Notes or any Note Guarantee, may amend or supplement this Indenture, the Notes or the Note Guarantees without notice to any other Holders. Subject to Section 6.07, the Holder or Holders of a majority in aggregate principal amount of the then outstanding Notes may waive compliance by the Company with any provision of this Indenture, the Notes or any Note Guarantee without notice to any other Holder. Without the consent of each Holder affected, however, no amendment, supplement or waiver, including a waiver pursuant to (and to the extent provided in) Section 6.04, may:

(1)    change the Stated Maturity of the principal of, or any installment of interest on, any Note;

(2)    reduce the principal amount of, or premium, if any, or interest on, any Note;

(3)    change the optional redemption dates or optional redemption prices of the Notes from that stated under Section 3.07 hereof;

(4)    change the place or currency of payment of principal of, or premium, if any, or interest on, any Note;

(5)    impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity (or, in the case of a redemption, on or after the redemption date) of any Note;

(6)    waive a default in the payment of principal of, premium, if any, or interest on the Notes;

(7)    release any Subsidiary Guarantor from its Note Guarantee, except as provided in this Indenture;

(8)    amend or modify any of the provisions of this Indenture in any manner which subordinates the Notes issued hereunder in right of payment to any other Indebtedness of the Company or which subordinates any Note Guarantee in right of payment to any other Indebtedness of the Subsidiary Guarantor issuing any such Note Guarantee; or

-65-

(9)    reduce the percentage or aggregate principal amount of outstanding Notes the consent of whose Holders is necessary for waiver of compliance with the provisions of this Indenture or for waiver of defaults under Section 6.02(a) or 6.04 hereof.

provided that: (a) the Company or Subsidiary Guarantor has delivered to the Trustee an Opinion of Counsel and an Officers’ Certificate, each stating that such amendment or supplement complies with the provisions of this Section 9.02; and (b) the Trustee has received evidence satisfactory to it that the requisite consent has been obtained.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, waiver or consent, but it shall be sufficient if such consent approves the substance thereof. For the avoidance of doubt, no amendment to, or deletion of any of the covenants described under Sections 4.06, 4.11 and 4.16 shall be deemed to impair or affect any rights of Holders of the Notes to receive payment of principal of, or premium, if any, or interest on, the Notes.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

For avoidance of doubt, changes to any notice provisions for any redemptions may be amended with the consent of Holders of a majority of the principal amount of Notes then outstanding.

Section 9.03    [Reserved].

Section 9.04    Revocation and Effect of Consents. Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to his Note or portion of his Note by notice to the Trustee or the Company received before the date on which the Trustee receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (1) through (9) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of, premium, if any, and interest on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder.

-66-

Section 9.05    Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note, the Company may require the Holder of the Note to deliver it to the Trustee. The Company shall provide the Trustee with an appropriate notation on the Note with respect to the changed terms and cause the Trustee to return it to the Holder at the Company’s expense. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06    Trustee to Sign Amendments, Etc. The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article 9; provided that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture. The Trustee shall be provided with, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate each complying with Sections 13.04 and 13.05 and stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article 9 is authorized or permitted by this Indenture and constitutes the legal, valid and binding obligations of the Company enforceable in accordance with its terms. Such Opinion of Counsel shall be at the expense of the Company.

Section 9.07    Additional Voting Terms. All Notes issued under this Indenture shall vote and consent together on all matters (as to which any Notes may vote) as one class.

ARTICLE 11

NOTE GUARANTEES

Section 11.01    Guarantee.

(a)    Subject to this Article 11, each of the Subsidiary Guarantors hereby, jointly and severally, unconditionally guarantees on a senior unsecured basis, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(1)    the principal of, premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly 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 any of such other obligations, that same will be promptly 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.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Subsidiary Guarantors shall be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

-67-

(b)    The Subsidiary Guarantors hereby agree that their obligations hereunder are 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 of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, 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 Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c)    If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Subsidiary Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Subsidiary Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

(d)    Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between the Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Subsidiary Guarantors for the purpose of this Note Guarantee. The Subsidiary Guarantors will have the right to seek contribution from any other Subsidiary Guarantor, or the Company, as the case may be, so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

Section 11.02    Limitation on Guarantor Liability. Each Subsidiary Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of such Subsidiary Guarantor shall be limited to the maximum amount that shall, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Subsidiary Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under this Article 11, result in the obligations of such Subsidiary Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 11.03    Execution and Delivery of Note Guarantees.

(a)    To evidence its Note Guarantee set forth in Section 11.01 hereof, each Subsidiary Guarantor hereby agrees that this Indenture shall be executed on behalf of such Subsidiary Guarantor by one of its Officers.

-68-

(b)    Each Subsidiary Guarantor hereby agrees that its Note Guarantee set forth in Section 11.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee.

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

(d)    The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute delivery of the Note Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors.

Section 11.04    Contribution. Each Subsidiary Guarantor that makes a payment or distribution under its Note Guarantee shall be entitled to contribution from any other Subsidiary Guarantor or the Company, as the case may be.

Section 11.05    Releases. The Note Guarantee issued by any Subsidiary Guarantor shall be automatically and unconditionally released and discharged:

(1)    upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary or an Excluded Subsidiary (other than pursuant to clause (1) of the definition thereof);

(2)    in connection with any sale of all or substantially all the assets or sale or other disposition of all or a majority of the Capital Stock of a Subsidiary Guarantor to a Person that is not the Company or (either before or after giving effect to such transaction) an Affiliate of the Company;

(3)    upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 or upon satisfaction and discharge of this Indenture in compliance with Article 12;

(4)    pursuant to the covenant termination in accordance with Section 4.16;

(5)    upon such Subsidiary Guarantor being (or being substantially concurrently) released or discharged from all of its obligations under all of its Guarantees of payment by the Company or any Indebtedness of the Company under the Credit Agreement or other debt, which resulted in the obligation to Guarantee the Notes, except a release as a result of payment under such Guarantee;

(6)    the merger or consolidation of such Subsidiary Guarantor with and into the Company or another Subsidiary Guarantor that is the surviving Person in such merger or consolidation, or upon the liquidation or dissolution of such Subsidiary Guarantor following the transfer of all or substantially all of its assets to the Company or another Subsidiary Guarantor; or

(7)    pursuant to the provisions of Article 9;

provided that such release or discharge shall not become effective until the receipt by the Trustee of an Officers’ Certificate stating that all conditions precedent to the release and discharge of the Guarantee have been complied with.

Any Subsidiary Guarantor not released from its obligations under its Note Guarantee as provided in this Section 11.05 shall remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Subsidiary Guarantor under this Indenture as provided in this Article 11.

-69-

Section 11.06    No Subrogation. Notwithstanding any payment or payments made by each Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Company or any other Guarantor or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the payment of the Note Guarantees, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on account of the Note Guarantee are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Note Guarantees shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Note Guarantees.

Section 11.07    Effectiveness of Guarantees. The Note Guarantee issued pursuant to this Article 11 shall be effective upon execution and delivery of this Indenture by the parties hereto.

Section 11.08    Discretion to Guarantee. The Company may elect, in its sole discretion, to cause any Subsidiary that is not otherwise required to Guarantee the Notes to become a Subsidiary Guarantor, in which case such Subsidiary shall not be required to comply with any deadline or timing requirement under this Indenture to become a Guarantor. Any Guarantee of the Notes provided by any such Subsidiary may be released at any time in the Company’s sole discretion.

Section 11.09    Benefits Acknowledged. Each Subsidiary Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the guarantee and waivers made by it pursuant to its Note Guarantee are knowingly made in contemplation of such benefits.

ARTICLE 12

SATISFACTION AND DISCHARGE

Section 12.01    Satisfaction and Discharge.

(a)    This Indenture shall be discharged and shall cease to be of further effect (except as to surviving rights of registration of transfer or exchange of the Notes, as expressly provided for in this Indenture) as to all outstanding Notes when:

(1)    either:

(A)    all of the Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust by the Company and thereafter repaid to the Company) have been delivered to the Trustee for cancellation, or

(B)    all Notes not theretofore delivered to the Trustee for cancellation have become due and payable pursuant to the sending of an optional redemption notice or otherwise or will become due and payable within one year, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the trustee for cancellation, for principal of, premium, if any, and interest on the Notes to (but excluding) the date of deposit together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; and

-70-

(2)    the Company has paid all other sums payable under this Indenture by the Company.

Subject to the next sentence and notwithstanding the foregoing paragraph, the Company’s obligations in Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 7.06, 8.04 and 12.02 of this Indenture shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.08. After the Notes are no longer outstanding, the Company’s obligations in Sections 7.06, 8.04 and 12.02 of this Indenture shall survive such satisfaction and discharge.

(b)    After such delivery or irrevocable deposit, the Trustee, upon delivery of an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with, shall acknowledge in writing the discharge of the Company’s obligations under the Notes and this Indenture except for those surviving obligations specified above.

Section 12.02    Application of Trust Money. Subject to the provisions of Section 8.04 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 12.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Subsidiary Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof; provided that if the Company has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

4.50% Senior Notes due 2028

Capitalized terms used herein but not defined have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1)     INTEREST. MasTec, Inc., a Florida corporation (the “Company”), promises to pay interest on the principal amount of this Note at 4.50% per annum from August 4, 2020 until maturity. Interest on the Notes will be payable semiannually in arrears February 15 and August 15 of each year, commencing on [                    ]¹, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance, until the principal hereof is due. The first Interest Payment Date shall be February 15, 2021 for the Initial Notes. The Company will pay interest on overdue principal at the rate borne by the Notes, and it shall pay interest on overdue installments of interest at the same rate borne by the Notes to the extent lawful. Interest will be computed on the basis of a 360 day year of twelve 30 day months.

(2)     METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the February 1 and August 1 immediately preceding the Interest Payment Date, as the case may be, even if such Notes are canceled after such Record Date and on or before such Interest Payment Date, except as provided in Section 2.12 of this Indenture with respect to defaulted interest. If a Holder has given wire transfer instructions to the Company and the Trustee, the Company will remit all principal, interest and premium, if any, on that Holder’s Notes in accordance with such instructions. All other payments on the Notes will be made at the office or agency of the Paying Agent and Registrar unless the Company elects to make interest payments by mailing a check to the registered address of each Holder thereof. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

(3)     PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National Association, as the Trustee, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

(4)     INDENTURE. The Company issued the Notes under an Indenture dated as of August 4, 2020 (herein called the “Indenture”) among the Company, the Subsidiary Guarantors named therein and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all the terms and provisions of the Indenture, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

The Notes are general senior unsecured obligations of the Company. This Note is one of the Notes referred to in the Indenture. The Notes include the Initial Notes and any Additional Notes. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends and other distributions and create or incur Liens. The Indenture also imposes limitations on the ability of the Company and each Subsidiary Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of its property.

(5)     OPTIONAL REDEMPTION.

(a)     Except as set forth in subparagraphs (b) and (c) of this Paragraph 5, the Company will not have the option to redeem the Notes prior to August 15, 2023. The Company may redeem the Notes, in whole or in part, upon not less than 10 nor more than 60 days’ notice, at any time on or after August 15, 2023. The redemption price for the Notes (expressed as a percentage of principal amount) will be as follows, plus accrued and unpaid interest, if any, to (but excluding) the redemption date, if redeemed during the 12-month period commencing on August 15 of any year set forth below:

Unless the Company defaults in the payment of the redemption or purchase price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

(b)     At any time prior to August 15, 2023, the Company may redeem up to 40% of the principal amount of the Notes with an amount equal to the amount of the net cash proceeds of one or more sales of Capital Stock (other than Disqualified Stock) of the Company at a redemption price (expressed as a percentage of principal amount) of 104.50%, plus accrued and unpaid interest to (but excluding) the redemption date; provided that at least 50% of the aggregate principal amount of the Notes originally issued under the Indenture on the Closing Date remains outstanding after each such redemption (excluding Notes held by the Company and its Subsidiaries) unless all such Notes are redeemed substantially concurrently and notice of any such redemption is mailed within 90 days of each such sale of Capital Stock.

Notes and portions of Notes selected will be in amounts of $2,000 or integral multiples of $1,000 in excess thereof; provided that no Notes of $2,000 in principal amount or less will be redeemed in part. Unless the Company defaults in the payment of the redemption or purchase price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

A-6
