“ Consolidated Leverage Ratio ” means, as of the date of determination, the ratio of (a) the Consolidated Indebtedness of the Covenant Parties and the Restricted Subsidiaries on such date less the amount of cash and Cash Equivalents in excess of any Restricted Cash that would be stated on the balance sheet of the Covenant Parties and the Restricted Subsidiaries and held by the Covenant Parties and the Restricted Subsidiaries as of such date of determination, as determined in accordance with GAAP, to (b) EBITDA of the Covenant Parties and the Restricted Subsidiaries for the most recently ended four fiscal quarters ending immediately prior to such date for which internal financial statements are available.

In the event that a Covenant Party or any Restricted Subsidiary (i) incurs, assumes, guarantees, redeems, retires or extinguishes any Indebtedness (other than, for purposes of calculating EBITDA only, Indebtedness incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and has not been replaced) or (ii) issues or redeems Disqualified Stock or Preferred Stock subsequent to the commencement of the period for which the Consolidated Leverage Ratio is being calculated but prior to or simultaneously with the event for which the calculation of the Consolidated Leverage Ratio is made (the “ Consolidated Leverage Ratio Calculation Date ”), then the Consolidated Leverage Ratio shall be calculated giving pro forma effect to such incurrence, assumption, guarantee, redemption, retirement or extinguishment of Indebtedness, or such issuance or redemption of Disqualified Stock or Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period.

For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, amalgamations, consolidations and discontinued operations (as determined in accordance with GAAP), in each case with respect to an operating unit of a business, and other operational changes that a Covenant Party or any of the Restricted Subsidiaries has determined to make and/or made during the four-quarter reference period or subsequent to such reference period and on or prior to or simultaneously with the Consolidated Leverage Ratio Calculation Date shall be calculated on a pro forma basis in accordance with GAAP assuming that all such Investments, acquisitions, dispositions, mergers, amalgamations, consolidations, discontinued operations and other operational changes (and the change in any associated Fixed Charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged with or into a Covenant Party or any of the Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, merger, amalgamation, consolidation, discontinued operation or operational change, in each case with respect to an operating unit of a business, that would have required adjustment pursuant to this definition, then the Consolidated Leverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, merger, consolidation, discontinued operation or operational change had occurred at the beginning of the applicable four-quarter period.

For purposes of this definition, whenever pro forma effect is to be given to a transaction, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of an Issuer. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Consolidated Leverage Ratio Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of an Issuer to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period except as set forth in the first paragraph of this definition. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuers

-7-

may designate. Any such pro forma calculation may include adjustments appropriate, in the reasonable determination of the Issuers as set forth in an Officer’s Certificate, to reflect (1) operating expense reductions and other operating improvements or synergies reasonably expected to result from any acquisition, amalgamation, merger or operational change (including, to the extent applicable, from the Transactions) and (2) all adjustments of the nature used in connection with the calculation of “Pro Forma Adjusted EBITDA” as set forth in footnote 8 to the “Summary Historical and Pro Forma Financial Information” under “Offering Memorandum Summary” in the Original Offering Memorandum, to the extent such adjustments, without duplication, continue to be applicable to such four-quarter period. Notwithstanding anything to the contrary, the aggregate amount of projected operating expense reductions, operating improvements and synergies included in any such pro forma calculation shall not exceed $125.0 million for any four consecutive quarter period (which adjustments may be incremental to pro forma adjustments made pursuant to the immediately preceding paragraph).

For the purposes of this definition, any amount in a currency other than U.S. dollars will be converted to U.S. dollars based on the average exchange rate for such currency for the most recent twelve-month period immediately prior to the date of determination determined in a manner consistent with that used in calculating EBITDA for the applicable period.

“ Consolidated Net Income ” means, with respect to any Person for any period, the aggregate of the Net Income of such Person and its Subsidiaries that are Covenant Parties or Restricted Subsidiaries for such period, on a consolidated basis, and otherwise determined in accordance with GAAP; provided , however , that, without duplication,

(2) the Net Income for such period shall not include the cumulative effect of a change in accounting principles during such period, including changes from international financial reporting standards to United States financial reporting standards,

(3) any after-tax effect of income (loss) from disposed or discontinued operations and any net after-tax gains or losses on disposal of disposed, abandoned or discontinued operations shall be excluded,

(4) any after-tax effect of gains or losses (less all fees and expenses relating thereto) attributable to asset dispositions other than in the ordinary course of business, as determined in good faith by the Issuers, shall be excluded,

(5) the Net Income for such period of any Person that is not a Subsidiary, or is an Unrestricted Subsidiary, or that is accounted for by the equity method of accounting, shall be excluded; provided that Consolidated Net Income of such Person shall be increased by the amount of dividends or distributions or other payments that are actually paid in cash (or to the extent converted into cash) to such Person or a Subsidiary thereof that is a Covenant Party or a Restricted Subsidiary in respect of such period,

(6) solely for the purpose of determining the amount available for Restricted Payments under clause (3)(a) of Section 4.07(a) hereof, the Net Income for such period of any Restricted Subsidiary (other than any Guarantor) shall be excluded if the declaration or payment of

-8-

dividends or similar distributions by that Restricted Subsidiary of its Net Income is not at the date of determination wholly permitted without any prior governmental approval (which has not been obtained) or, directly or indirectly, by the operation of the terms of its charter or any agreement, instrument, judgment, decree, order, statute, rule, or governmental regulation applicable to that Restricted Subsidiary or its stockholders, unless such restriction with respect to the payment of dividends or similar distributions has been legally waived, provided that Consolidated Net Income of the Covenant Parties will be increased by the amount of dividends or other distributions or other payments actually paid in cash (or to the extent converted into cash) to a Covenant Party or a Restricted Subsidiary thereof in respect of such period, to the extent not already included therein,

(7) effects of purchase accounting adjustments (including the effects of such adjustments pushed down to such Person and such Subsidiaries) in component amounts required or permitted by GAAP, resulting from the application of purchase accounting in relation, to the Transactions or any consummated acquisition or the amortization or write-off of any amounts thereof, net of taxes, shall be excluded,

(8) any after-tax effect of income (loss) from the early extinguishment of Indebtedness or Hedging Obligations or other derivative instruments shall be excluded,

(9) any impairment charge or asset write-off, in each case, pursuant to GAAP and the amortization of intangibles arising pursuant to GAAP shall be excluded,

(10) any non-cash compensation expense recorded from grants of stock appreciation or similar rights, stock options, restricted stock or other rights shall be excluded,

(11) any fees and expenses incurred during such period, or any amortization thereof for such period, in connection with the Transactions and any acquisition, Investment, Asset Sale, issuance or repayment of Indebtedness, issuance of Equity Interests, refinancing transaction or amendment or modification of any debt instrument (in each case, including any such transaction consummated prior to August 9, 2006 and any such transaction undertaken but not completed) and any charges or non-recurring merger costs incurred during such period as a result of any such transaction shall be excluded, and

(12) accruals and reserves that are established within twelve months after August 9, 2006 that are so required to be established as a result of the Transactions in accordance with GAAP shall be excluded.

Notwithstanding the foregoing, for the purpose of Section 4.07 hereof only (other than clause (3)(d) of Section 4.07(a) hereof), there shall be excluded from Consolidated Net Income any income arising from any sale or other disposition of Restricted Investments made by the Covenant Parties and the Restricted Subsidiaries, any repurchases and redemptions of Restricted Investments from the Covenant Parties and the Restricted Subsidiaries, any repayments of loans and advances which constitute Restricted Investments by any of the Covenant Parties or any of the Restricted Subsidiaries, any sale of the stock of an Unrestricted Subsidiary or any distribution or dividend from an Unrestricted Subsidiary, in each case only to the extent such amounts increase the amount of Restricted Payments permitted under clause (3)(d) of Section 4.07(a) hereof.

“ Consolidated Secured Debt Ratio ” means, as of the date of determination, the ratio of (a) the Consolidated Indebtedness of the Covenant Parties and the Restricted Subsidiaries on such date that is secured by Liens  less the amount of cash and Cash Equivalents in excess of any Restricted Cash

-9-

that would be stated on the balance sheet of the Covenant Parties and the Restricted Subsidiaries and held by the Covenant Parties and the Restricted Subsidiaries as of such date of determination, as determined in accordance with GAAP, to (b) EBITDA of the Covenant Parties and the Restricted Subsidiaries for the most recently ended four fiscal quarters ending immediately prior to such date for which internal financial statements are available.

In the event that a Covenant Party or any Restricted Subsidiary (i) incurs, assumes, guarantees, redeems, retires or extinguishes any Indebtedness (other than, for purposes of calculating EBITDA only, Indebtedness incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and has not been replaced) or (ii) issues or redeems Disqualified Stock or Preferred Stock subsequent to the commencement of the period for which the Consolidated Secured Debt Ratio is being calculated but prior to or simultaneously with the event for which the calculation of the Consolidated Secured Debt Ratio is made (the “ Consolidated Secured Debt Ratio Calculation Date ”), then the Consolidated Secured Debt Ratio shall be calculated giving pro forma effect to such incurrence, assumption, guarantee, redemption, retirement or extinguishment of Indebtedness, or such issuance or redemption of Disqualified Stock or Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period.

For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, amalgamations, consolidations and discontinued operations (as determined in accordance with GAAP), in each case with respect to an operating unit of a business, and other operational changes that a Covenant Party or any of the Restricted Subsidiaries has determined to make and/or made during the four-quarter reference period or subsequent to such reference period and on or prior to or simultaneously with the Consolidated Secured Debt Ratio Calculation Date shall be calculated on a pro forma basis in accordance with GAAP assuming that all such Investments, acquisitions, dispositions, mergers, amalgamations, consolidations, discontinued operations and other operational changes (and the change in any associated Fixed Charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged with or into a Covenant Party or any of the Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, merger, amalgamation, consolidation, discontinued operation or operational change, in each case with respect to an operating unit of a business, that would have required adjustment pursuant to this definition, then the Consolidated Secured Debt Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, merger, consolidation, discontinued operation or operational change had occurred at the beginning of the applicable four-quarter period.

For purposes of this definition, whenever pro forma effect is to be given to a transaction, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of an Issuer. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Consolidated Secured Debt Ratio Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of an Issuer to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period except as set forth in the first paragraph of this definition. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuers

-10-

may designate. Any such pro forma calculation may include adjustments appropriate, in the reasonable determination of the Issuers as set forth in an Officer’s Certificate, to reflect (1) operating expense reductions and other operating improvements or synergies reasonably expected to result from any acquisition, amalgamation, merger or operational change (including, to the extent applicable, from the Transactions); and (2) all adjustments of the nature used in connection with the calculation of “Pro Forma Adjusted EBITDA” as set forth in footnote 8 to the “Summary Historical and Pro Forma Financial Information” under “Offering Memorandum Summary” in the Original Offering Memorandum, to the extent such adjustments, without duplication, continue to be applicable to such four-quarter period. Notwithstanding anything to the contrary, the aggregate amount of projected operating expense reductions, operating improvements and synergies included in any such pro forma calculation shall not exceed $125.0 million for any four consecutive quarter period (which adjustments may be incremental to pro forma adjustments made pursuant to the immediately preceding paragraph).

For the purposes of this definition, any amount in a currency other than U.S. dollars will be converted to U.S. dollars based on the average exchange rate for such currency for the most recent twelve month period immediately prior to the date of determination determined in a manner consistent with that used in calculating EBITDA for the applicable period.

“ Contingent Obligations ” means, with respect to any Person, any obligation of such Person guaranteeing any leases, dividends or other obligations that do not constitute Indebtedness (“ primary obligations ”) of any other Person (the “ primary obligor ”) in any manner, whether directly or indirectly, including, without limitation, any obligation of such Person, whether or not contingent,

A Note shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated substantially in the form of Exhibit A attached hereto by the manual or facsimile signature of the Trustee. The signature shall be conclusive evidence that the Note has been duly authenticated and delivered under this Indenture.

On the Issue Date, the Trustee shall, upon receipt of an Issuer Order (an “ Authentication Order ”), authenticate and deliver the Initial Notes. In addition, at any time, from time to time, the Trustee shall upon receipt of an Authentication Order authenticate and deliver any Additional Notes and Exchange Notes for an aggregate principal amount specified in such Authentication Order for such Additional Notes or Exchange Notes issued hereunder.

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

The Issuers shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for exchange (“ Registrar ”) and (ii) an office or agency in the Borough of Manhattan, the City of New York, the State of New York, where Notes may be presented for payment (the “ Paying Agent ”). The Registrar shall keep a register of the Notes (“ Note Register ”) and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar. The Issuers shall maintain a registrar in the Borough of Manhattan, City of New York, the State of New York. The term “ Paying Agent ” includes the Paying Agent and any additional paying agents. The Issuers initially appoint DBTCA as (i) Registrar and Paying Agent in connection with the Notes and (ii) the Custodian with respect to the Global Notes. The Issuers may change the Paying Agent or Registrar without prior notice to any Holder. The Issuers shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Covenant Parties or any of their respective Subsidiaries may act as Paying Agent or Registrar. All Agents appointed under this Indenture shall be appointed pursuant to agency agreements among the Issuers, the Trustee and the Agent, as applicable.

The Issuers initially appoint The Depository Trust Company (“ DTC ”) to act as Depositary with respect to the Global Notes.

The Issuers 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 Additional Interest, if any, or interest on the Notes, and will notify the Trustee in writing of any default by the Issuers 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 Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than a Covenant Party or one of their respective Subsidiaries) shall have no further liability for the money. If a Covenant Party or one of their respective Subsidiaries 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 a Covenant Party, DBTCA shall serve as Paying Agent.

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 and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee at least two 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 and the Issuers shall otherwise comply with Trust Indenture Act Section 312(a).

At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

-47-

(iii) Neither the Registrar nor the Issuers shall be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

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

(v) The Issuers shall not be required (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 so 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.

(vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuers 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 premium, if any) and interest (including Additional Interest, if any) on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuers shall be affected by notice to the contrary.

(vii) Upon surrender for registration of transfer of any Note at the office or agency of the Issuers designated pursuant to Section 4.02 hereof, the Issuers shall execute, and the Trustee shall authenticate and mail, in the name of the designated transferee or transferees, one or more replacement Notes of any authorized denomination or denominations of a like aggregate principal amount.

(viii) At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations of a like aggregate principal amount upon surrender of the Notes to be exchanged at such office or agency.

(ix) 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.

If any mutilated Note is surrendered to the Trustee, the Registrar or the Issuers and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Note, the Issuers shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers may charge for their expenses in replacing a Note.

Every replacement Note is a contractual obligation of the Issuers and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

-48-

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 Issuers or an Affiliate of the Issuers holds the Note.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide 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 a Covenant Party, a Subsidiary of a Covenant Party or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuers, or by any Affiliate of the Issuers, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not an Issuer or any obligor upon the Notes or any Affiliate of an Issuer or of such other obligor.

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

Holders and beneficial holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to Holders, or beneficial holders, respectively, of Notes under this Indenture.

The Issuers 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 or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of such cancelled Notes (subject to the record retention requirement

-49-

of the Exchange Act) in accordance with its customary procedures. Certification of the disposition of all cancelled Notes shall be delivered to the Issuers upon their written request. The Issuers may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation.

If the Issuers default in a payment of interest on a series of Notes, they shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest to the Persons who are Holders of Notes of such series on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuers shall notify the Trustee (and the applicable Paying Agent) in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section 2.12. The Trustee shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. The Trustee shall promptly notify the Issuers of such special record date. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) shall mail or cause to be mailed, first-class postage prepaid, to each Holder a notice at his or her address as it appears in the Note Register that states the special record date, the related payment date and the amount of such interest to be paid.

Subject to the foregoing provisions of this Section 2.12 and for greater certainty, 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.

The Issuers in issuing the Notes may use CUSIP numbers and, if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to Holders; provided , that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuers will as promptly as practicable notify the Trustee in writing of any change in the CUSIP numbers.

The aggregate principal amount of the Notes, at any date of determination, shall be the principal amount of the Notes outstanding at such date of determination. With respect to any matter requiring consent, waiver, approval or other action of the Holders of a specified percentage of the principal amount of all the Notes, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Notes, the Holders of which have so consented, by (b) the aggregate principal amount, as of such date of determination, of the Notes then outstanding, in each case, as determined in accordance with the preceding sentence, Section 2.08 and Section 2.09 of this Indenture. Any such calculation made pursuant to this Section 2.14 shall be made by the Issuers and delivered to the Trustee pursuant to an Officers’ Certificate.

In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

(1) in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of more than one of the categories of permitted Indebtedness, Disqualified Stock or Preferred Stock described in clauses (1) through (21) of Section 4.09(b) hereof or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Issuers, in their sole discretion, shall classify or reclassify such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) and shall only be required to include the amount and type of such Indebtedness, Disqualified Stock or Preferred Stock in one of the above clauses; provided that all Indebtedness outstanding under the Credit Facilities on the Issue Date shall be treated as incurred on the Issue Date under clause (1) of Section 4.09(b) hereof; and

(2) at the time of incurrence, the Issuers will be entitled to divide and classify an item of Indebtedness in more than one of the types of Indebtedness described in Section 4.09(a) and Section 4.09(b) hereof.

Accrual of interest, the accretion of accreted value and the payment of interest or dividends in the form of additional Indebtedness, Disqualified Stock or Preferred Stock, as applicable, will not be deemed to be an incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this Section 4.09.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced.

-72-

The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such refinancing.

Notwithstanding anything to the contrary, the Issuers shall not, and shall not permit any Restricted Guarantor to, directly or indirectly, incur any Indebtedness (including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of the Issuers or such Restricted Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in right of payment to the Notes or such Restricted Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Issuers or such Restricted Guarantor, as the case may be.

For the purposes of this Indenture, Indebtedness that is unsecured is not deemed to be subordinated or junior to Secured Indebtedness merely because it is unsecured, and Senior Indebtedness is not deemed to be subordinated or junior to any other Senior Indebtedness merely because it has a junior priority with respect to the same collateral.

(a) The Covenant Parties shall not, and shall not permit any of the Restricted Subsidiaries to, cause, make or suffer to exist an Asset Sale, unless:

(1) a Covenant Party or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by the Issuers) of the assets sold or otherwise disposed of; and

(2) except in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by a Covenant Party or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; provided that the amount of:

(A) any liabilities (as shown on such Covenant Party’s or such Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto) of a Covenant Party or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes, that are assumed by the transferee of any such assets and for which the Covenant Parties and all of the Restricted Subsidiaries have been validly released by all creditors in writing,

(B) any securities received by such Covenant Party or such Restricted Subsidiary from such transferee that are converted by such Covenant Party or such Restricted Subsidiary into cash (to the extent of the cash received) within 180 days following the closing of such Asset Sale, and

(C) any Designated Non-cash Consideration received by such Covenant Party or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed 5.0% of Total Assets at the time of the receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value,

-73-

shall be deemed to be cash for purposes of this provision and for no other purpose.

(b) Within 15 months after the receipt of any Net Proceeds of any Asset Sale, such Covenant Party or such Restricted Subsidiary, at its option, may apply the Net Proceeds from such Asset Sale,

(1) to permanently reduce:

(A) Obligations under the Senior Credit Facilities and to correspondingly reduce commitments with respect thereto;

(B) Obligations under the Senior Indebtedness that is secured by a Lien, which Lien is permitted by this Indenture, and to correspondingly reduce commitments with respect thereto;

(C) Obligations under (i) Notes (to the extent such purchases are at or above 100% of the principal amount thereof) or (ii) any other Senior Indebtedness of an Issuer or a Restricted Guarantor (and to correspondingly reduce commitments with respect thereto); provided that the Issuers shall equally and ratably reduce Obligations under the Notes as provided under Section 3.07 hereof through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with this Section 4.10(c) hereof) to all Holders of Notes to purchase their Notes at 100% of the principal amount thereof, plus, in the case of each of clauses (i) and (ii), the amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be prepaid;

(D) Indebtedness of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to a Covenant Party or another Restricted Subsidiary; or

(E) Obligations under Subordinated Indebtedness in an aggregate principal amount not to exceed the Asset Sale Prepayment Amount; or

(2) to make (A) an Investment in any one or more businesses, provided that such Investment in any business is in the form of the acquisition of Capital Stock and results in a Covenant Party or Restricted Subsidiary, as the case may be, owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (B) properties, (C) capital expenditures or (D) acquisitions of other assets that, in the case of each of (A), (B), (C) and (D) are either (x) used or useful in a Similar Business or (y) replace the businesses, properties and/or assets that are the subject of such Asset Sale;

provided that, in the case of clause (2) above, a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as the Covenant Party, or such other Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days of such commitment (an “ Acceptable Commitment ”) and, in the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith, such Covenant Party or such Restricted Subsidiary enters into another Acceptable Commitment (a “ Second Commitment ”) within 180 days of such cancellation or termination; provided further that if any Second Commitment is later cancelled or terminated

-74-

for any reason before such Net Proceeds are applied, then such Net Proceeds shall constitute Excess Proceeds. Notwithstanding anything to the contrary, any Net Proceeds from the sale, transfer, conveyance or other disposal of all or substantially all of the assets of ACN and its Subsidiaries that are Restricted Subsidiaries to the extent otherwise permitted under this Indenture, will be applied in accordance with this paragraph within 12 months after receipt of such Net Proceeds, and the proviso to the previous sentence with respect to Acceptable Commitments and Second Commitments will not be applicable to the application of such Net Proceeds.

(c) Any Net Proceeds from the Asset Sale that are not invested or applied as provided and within the time period set forth in Section 4.10(b) will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $100.0 million, the Issuers shall make an offer to all Holders of the Notes and, if required by the terms of any Indebtedness that is pari passu with the Notes (“ Pari Passu Indebtedness ”), to the holders of such Pari Passu Indebtedness (an “ Asset Sale Offer ”), to purchase the maximum aggregate principal amount of the Notes and such Pari Passu Indebtedness that is a minimum of $2,000 or an integral multiple of $1,000 (in each case in aggregate principal amount), that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Issuers shall commence an Asset Sale Offer with respect to Excess Proceeds within ten Business Days after the date that Excess Proceeds exceed $100.0 million by mailing the notice required pursuant to the terms of this Indenture, with a copy to the Trustee.

To the extent that the aggregate principal amount of Notes and such Pari Passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuers may use any remaining Excess Proceeds for general corporate purposes, subject to the other covenants contained in this Indenture. If the aggregate principal amount of Notes and the Pari Passu Indebtedness surrendered in an Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such Pari Passu Indebtedness to be purchased on a pro rata basis based on the principal amount of the Notes and such Pari Passu Indebtedness tendered. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(d) Pending the final application of any Net Proceeds pursuant to this covenant, the holder of such Net Proceeds may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture.

(e) The Issuers shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

(a) The Covenant Parties shall not, and shall not permit any of the Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Issuers (each of the foregoing, an “ Affiliate Transaction ”) involving aggregate payments or consideration in excess of $20.0 million, unless:

(1) such Affiliate Transaction is on terms that are not materially less favorable to the relevant Covenant Party or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by such Covenant Party or such Restricted Subsidiary with an unrelated Person on an arm’s-length basis; and

-75-

(2) the Issuers deliver to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $50.0 million, a resolution adopted by the majority of the board of directors of the Issuers approving such Affiliate Transaction and set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 4.11(a).

(b) The provisions of Section 4.11(a) hereof shall not apply to the following:

(6) any agreement as in effect as of August 9, 2006 or any amendment thereto (so long as any such amendment is not disadvantageous to the Holders when taken as a whole as compared to the applicable agreement as in effect on August 9, 2006);

(7) the existence of, or the performance by the Covenant Parties or any of the Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of August 9, 2006 and any similar agreements which it may enter into thereafter; provided , however , that the existence of, or the performance by the Covenant Parties or any of the Restricted Subsidiaries of obligations under any future amendment to any such existing agreement or under any similar agreement entered into after August 9, 2006 shall only be permitted by this clause (7) to the extent that the terms of any such amendment or new agreement are not otherwise disadvantageous to the Holders when taken as a whole;

The Covenant Parties will not permit any Restricted Subsidiary that is a Wholly-Owned Subsidiary of a Covenant Party (and non-Wholly-Owned Subsidiaries if such non-Wholly-Owned Subsidiaries guarantee other capital markets debt securities), other than a Guarantor or a Foreign Subsidiary of a Domestic Subsidiary, to guarantee the payment of any Indebtedness of the Issuers or any other Guarantor unless:

(1) such Restricted Subsidiary within 30 days executes and delivers a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto, providing for a Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of the Issuers or any Guarantor:

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

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

(2) such Restricted Subsidiary shall within 30 days deliver to the Trustee an Opinion of Counsel reasonably satisfactory to the Trustee;

provided that this Section 4.15 shall not be applicable to any guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary.

(a) During any period of time that: (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “ Covenant Suspension Event ”), the Covenant Parties and the Restricted Subsidiaries shall not be subject to Section 4.07 hereof, Section 4.08 hereof, Section 4.09 hereof, Section 4.10 hereof, Section 4.11 hereof, Section 4.14 hereof, Section 4.15 hereof and clause (4) of Section 5.01 hereof (the “ Suspended Covenants ”).

(b) In the event that the Covenant Parties and the Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “ Reversion Date ”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating then the Covenant Parties and the Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants under this Indenture. The period of time between the Covenant Suspension Event and the Reversion Date is referred to herein as the “ Suspension Period ”.

-80-

(c) In the event that the Covenant Parties and the Restricted Subsidiaries are not subject to the Suspended Covenants and the Issuers or any of their Affiliates enter into an agreement to effect a transaction that would result in a Change of Control and one or more of the Rating Agencies indicate that if consummated, such transaction (alone or together with any related recapitalization or refinancing transactions) would cause such Rating Agency to withdraw its Investment Grade Rating or downgrade the ratings assigned to the Notes below an Investment Grade Rating, then the Covenant Parties and the Restricted Subsidiaries shall thereafter again be subject to Section 4.14 hereof with respect to future events, including, without limitation, a proposed transaction described in this clause (c).

(d) On each Reversion Date, all Indebtedness Incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period will be classified as having been Incurred or issued pursuant to Section 4.09(a) or Section 4.09(b) (to the extent such Indebtedness or Disqualified Stock or Preferred Stock would be permitted to be Incurred or issued thereunder as of the Reversion Date and after giving effect to Indebtedness Incurred or issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness or Disqualified Stock or Preferred Stock would not be so permitted to be Incurred or issued pursuant to Sections 4.09(a) or (b), such Indebtedness or Disqualified Stock or Preferred Stock will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.09(b)(3). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.07 will be made as though Section 4.07 had been in effect since the Issue Date and throughout the Suspension Period. For the avoidance of doubt, Restricted Payments made during the Suspension Period shall reduce the amount available to be made as Restricted Payments under Section 4.07(a). No Default or Event of Default shall be deemed to have occurred on the Reversion Date as a result of any actions taken by the Covenant Parties or the Restricted Subsidiaries during the Suspension Period. For purposes of Section 4.10, on the Reversion Date, the unutilized Excess Proceeds amount shall be reset to zero.

(e) The Issuers shall deliver promptly to the Trustee an Officer’s Certificate notifying it of any such occurrence under this Section 4.16.

(i) such default either results from the failure to pay any principal of such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods) or relates to an obligation other than the obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its stated maturity; and

(ii) the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate $100.0 million or more at any one time outstanding;

(b) In the event of any Event of Default specified in clause (4) of Section 6.01(a) hereof, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 20 days after such Event of Default arose:

(1) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged; or

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

(3) the default that is the basis for such Event of Default has been cured.

-85-

(a) If any Event of Default (other than an Event of Default specified in clause (6) or (7) of Section 6.01(a) hereof) occurs and is continuing under this Indenture, the Trustee or the Holders of at least 30% in principal amount of the then total outstanding Notes may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately; provided , however , that so long as any Indebtedness permitted to be incurred under this Indenture as part of the Senior Credit Facilities shall be outstanding, no such acceleration shall be effective until the earlier of:

(1) acceleration of any such Indebtedness under the Senior Credit Facilities; or

(2) five Business Days after the giving of written notice of such acceleration to the Issuers and the administrative agent under the Senior Credit Facilities.

Upon the effectiveness of such declaration, such principal and interest shall be due and payable immediately. The Trustee shall have no obligation to accelerate the Notes if and so long as a committee of its Responsible Officers in good faith determines acceleration is not in the best interest of the Holders of the Notes.

(b) Notwithstanding the foregoing, in the case of an Event of Default arising under clause (6) or (7) of Section 6.01(a) hereof, all outstanding Notes shall be due and payable immediately without further action or notice.

(c) The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest, Additional Interest, if any, or premium that has become due solely because of the acceleration) have been cured or waived.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and 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. All remedies are cumulative to the extent permitted by law.

Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default and its consequences hereunder, except a continuing Default in the payment of the principal of, premium, if any, Additional Interest, if any, or interest on, any Note held by a non-consenting Holder (including in connection with an Asset Sale Offer or a Change of Control Offer); provided , subject to Section 6.02 hereof,

-86-

that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Holders of a majority in principal amount of the then total outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee in personal liability.

Subject to Section 6.07 hereof, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

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

(2) Holders of at least 30% in principal amount of the total outstanding Notes have requested the Trustee to pursue the remedy;

(3) Holders of the Notes have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

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

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

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

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and Additional Interest, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an Asset Sale Offer or a Change of Control Offer), 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.

-87-

If an Event of Default specified in Section 6.01(a)(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium, if any, and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest 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.

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 Issuers, 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.

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.

No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes including the Guarantors), its creditors or its property and shall be entitled and empowered to participate as a member in any official committee of creditors appointed in such matter and to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses,

-88-

disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 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, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

If the Trustee or any Agent (if the Agent shall receive any such funds, it shall remit them promptly to the Trustee) collects any money pursuant to this Article 6, it shall pay out the money in the following order:

(i) to the Trustee, the Agents, their agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee or any Agent and the costs and expenses of collection;

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

(iii) to the Issuers or to such party as a court of competent jurisdiction shall direct including a Guarantor, if applicable.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.13.

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 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 6.14 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

ARTICLE 7

TRUSTEE

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

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuers shall be sufficient if signed by an Officer of each Issuer.

(h) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee 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 DBTCA, custodian and other Person employed to act hereunder.

(j) In the event the Issuers are required to pay Additional Interest, the Issuers will provide written notice to the Trustee of the Issuers’ obligation to pay Additional Interest no later than 15 days prior to the next Interest Payment Date, which notice shall be in the form of an Officer’s Certificate and shall set forth the amount of the Additional Interest to be paid by the Issuers. The Trustee shall not at any time be under any duty or responsibility to any Holders to determine whether the Additional Interest is payable and the amount thereof.

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

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or any Affiliate of the Issuers with the same rights it would

-91-

have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default within 90 days after it occurs. Except in the case of a Default relating to the payment of principal, premium, if any, or interest on any Note, the Trustee may withhold from the Holders notice of any continuing Default if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. The Trustee shall not be deemed to know of any Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is such a Default is received by the Trustee at the Corporate Trust Office of the Trustee.

Within 60 days after each May 15, beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with Trust Indenture Act Section 313(a) (but if no event described in Trust Indenture Act Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with Trust Indenture Act Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by Trust Indenture Act Section 313(c).

A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to each Issuer and filed with the SEC and each stock exchange on which the Notes are listed in accordance with Trust Indenture Act Section 313(d). The Issuers shall promptly notify the Trustee when the Notes are listed on any stock exchange.

The Issuers shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder 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 Issuers shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

-92-

The Issuers and the Guarantors, jointly and severally, shall indemnify the Trustee for, and hold the Trustee harmless against, any and all loss, damage, claims, liability or expense (including attorneys’ fees) incurred by it in connection with the acceptance or administration of this trust and the performance of its duties hereunder (including the costs and expenses of enforcing this Indenture against the Issuers or any of the Guarantors (including this Section 7.07) or defending itself against any claim whether asserted by any Holder, the Issuers or any Guarantor, or liability in connection with the acceptance, exercise or performance of any of its powers or duties hereunder). The Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the Issuers of their obligations hereunder. The Issuers shall defend the claim and the Trustee may have separate counsel and the Issuers shall pay the fees and expenses of such counsel. The Issuers need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct, negligence or bad faith.

The obligations of the Issuers under this Section 7.07 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee.

To secure the payment obligations of the Issuers and the Guarantors in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(a)(6) or (7) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

The Trustee shall comply with the provisions of Trust Indenture Act Section 313(b)(2) to the extent applicable.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if:

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

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(c) a custodian or public officer takes charge of the Trustee or its property; or

(d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuers shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers.

-93-

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

If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee.

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, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.

This Indenture shall always have a Trustee who satisfies the requirements of Trust Indenture Act Sections 310(a)(1), (2) and (5). The Trustee is subject to Trust Indenture Act Section 310(b).

The Trustee is subject to Trust Indenture Act Section 311(a), excluding any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated therein.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

The Issuers may, at their option and at any time, elect to have either Section 8.02 or 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

-94-

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes and Guarantees on the date the conditions set forth below are satisfied (“ Legal Defeasance ”). For this purpose, Legal Defeasance means that the Issuers 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 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all their other obligations under such Notes and this Indenture including that of the Guarantors (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(a) the rights of Holders of Notes to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due solely out of the trust created pursuant to this Indenture referred to in Section 8.04 hereof;

(b) the Issuers’ obligations with respect to Notes concerning issuing temporary Notes, registration of such Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

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

(d) this Section 8.02.

Subject to compliance with this Article 8, the Issuers may exercise their option under this Section 8.02 notwithstanding the prior exercise of their option under Section 8.03 hereof.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.15 hereof and clauses (4) and (5) of Section 5.01(a), Sections 5.01(c) and 5.01(d) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (“ 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, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuers 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 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3), 6.01(4), 6.01(5), 6.01(6) (solely with respect to Restricted Subsidiaries that are Significant Parties), 6.01(7) (solely with respect to Restricted Subsidiaries that are Significant Parties) and 6.01(8) hereof shall not constitute Events of Default.

-95-

The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes:

In order to exercise either Legal Defeasance or Covenant Defeasance with respect to the Notes:

(1) the Issuers must irrevocably deposit with DBTCA, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination thereof, rated AAA or better by S&P and Aaa or better by Moody’s, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal amount of, premium, if any, and interest due on the Notes on the stated maturity date or on the redemption date, as the case may be, of such principal amount, premium, if any, or interest on such Notes and the Issuers must specify whether such Notes are being defeased to maturity or to a particular redemption date;

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

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

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

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, subject to customary assumptions and exclusions, the Holders of the Notes will not recognize income, gain or loss for U.S. federal income tax purposes, as applicable, as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

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

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

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the Senior Credit Facilities, the Existing Senior or the indentures pursuant to which the Existing Senior Notes were issued or any other material agreement

-96-

or instrument (other than this Indenture) to which, the Issuers or any Restricted Guarantor is a party or by which the Issuers or any Restricted Guarantor is bound (other than that resulting from any borrowing of funds to be applied to make the deposit required to effect such Legal Defeasance or Covenant Defeasance and any similar and simultaneous deposit relating to other Indebtedness, and the granting of Liens in connection therewith);

(6) the Issuers shall have delivered to the Trustee an Opinion of Counsel to the effect that, as of the date of such opinion and subject to customary assumptions and exclusions following the deposit, the trust funds will not be subject to the effect of Section 547 of Title 11 of the United States Code;

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

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

Subject to Section 8.06 hereof, all money and Government Securities (including the proceeds thereof) deposited with DBTCA (or other qualifying trustee, collectively for purposes of this Section 8.05, the “ Trustee ”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by DBTCA in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuers or a Guarantor acting as Paying Agent), as DBTCA may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and Additional Interest, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuers shall pay and indemnify the Trustee, and DBTCA against any tax, fee or other charge imposed on or assessed against the cash or Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article 8 to the contrary notwithstanding, DBTCA shall deliver or pay to the Issuers from time to time upon the request of the Issuers any money or Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to DBTCA (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

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

-97-

If DBTCA or the Paying Agent is unable to apply any United States dollars or Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided that, if the Issuers make any payment of principal of, premium and Additional Interest, if any, or interest on any Note following the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee, DBTCA or the Paying Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Notwithstanding Section 9.02 hereof, the Issuers, any Guarantor (with respect to a Guarantee or this Indenture) and the Trustee may amend or supplement this Indenture and any Guarantee or Notes without the consent of any Holder:

(1) to cure any ambiguity, omission, mistake, defect or inconsistency;

(2) to provide for uncertificated Notes of such series in addition to or in place of certificated Notes;

(3) to comply with Section 5.01 hereof;

(4) to provide the assumption of an Issuer’s or any Guarantor’s obligations to the Holders;

(5) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under this Indenture of any such Holder;

(6) to add covenants for the benefit of the Holders or to surrender any right or power conferred upon an Issuer or any Guarantor;

(7) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the Trust Indenture Act;

(8) to evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee thereunder pursuant to the requirements thereof;

(9) to provide for the issuance of exchange notes or private exchange notes, which are identical to exchange notes except that they are not freely transferable;

-98-

(10) to add a Guarantor under this Indenture;

(11) to conform the text of this Indenture, Guarantees or the Notes to any provision of the “Description of notes” section of the Offering Memorandum to the extent that such provision in such “Description of notes” section was intended to be a verbatim recitation of a provision of this Indenture, Guarantee or Notes; or

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

Upon the request of the Issuers accompanied by resolutions of each of their boards of directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Issuers and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. Notwithstanding the foregoing, no Opinion of Counsel shall be required in connection with the addition of a Guarantor under this Indenture upon execution and delivery by such Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto, and delivery of an Officer’s Certificate.

Except as provided below in this Section 9.02, the Issuers and the Trustee may amend or supplement this Indenture, the Notes and the Guarantees with the consent of the Holders of at least a majority in principal amount of the Notes (including Additional Notes, if any) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium and Additional Interest, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Guarantees or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof and Section 2.09 hereof shall determine which Notes are considered to be “outstanding” for the purposes of this Section 9.02.

Upon the request of the Issuers accompanied by resolutions of each of their boards of directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Issuers in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

-99-

It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

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

Without the consent of each affected Holder of Notes, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(2) reduce the principal amount of or change the fixed final maturity of any such Note or alter or waive the provisions with respect to the redemption of such Notes (other than provisions relating to Section 3.09, Section 4.10 and Section 4.14 hereof to the extent that any such amendment or waiver does not have the effect of reducing the principal of or changing the fixed final maturity of any such Note or altering or waiving the provisions with respect to the redemption of such Notes);

(3) reduce the rate of or change the time for payment of interest on any Note;

(4) waive a Default in the payment of principal of or premium, if any, or interest on the Notes, except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration, or in respect of a covenant or provision contained in this Indenture or any Guarantee which cannot be amended or modified without the consent of all Holders;

(5) make any Note payable in money other than that stated therein;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to receive payments of principal of or premium, if any, or interest on the Notes;

(7) make any change in these amendment and waiver provisions;

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

(9) make any change to the ranking of the Notes that would adversely affect the Holders; or

(10) except as expressly permitted by this Indenture, modify the Guarantees of any Significant Party in any manner adverse to the Holders of the Notes.

-100-

Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the Trust Indenture Act as then in effect.

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

The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement, or waiver. If a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or 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 120 days after such record date unless the consent of the requisite number of Holders has been obtained.

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

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

The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. Each Issuer may not sign an amendment, supplement or waiver until its board of directors approves it. In executing any amendment, supplement or waiver, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officer’s Certificate (from each Issuer) and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuers and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03). Notwithstanding the foregoing, no Opinion of Counsel will be required for the Trustee to execute any amendment or supplement adding a new Guarantor under this Indenture.

-101-

Neither the Issuers nor any Affiliate of either Issuer shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to all Holders and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

Except as provided in the proviso to the first sentence of Section 9.02, all Notes issued under this Indenture shall vote and consent together on all matters (as to which any of such Notes may vote) as one class and no series of Notes will have the right to vote or consent as a separate series on any matter. Determinations as to whether Holders of the requisite aggregate principal amount of Notes have concurred in any direction, waiver or consent shall be made in accordance with this Article 9 and Section 2.14.

ARTICLE 10

GUARANTEES

Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees 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 Issuers hereunder or thereunder, that: (a) the principal of, interest, premium and Additional Interest, if any, on the Notes shall 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 Issuers to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall 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 Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

-102-

Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01.

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

Each 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 Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) 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) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantees.

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

In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

The Guarantee issued by any Guarantor shall be a general unsecured senior obligation of such Guarantor and shall be pari passu in right of payment with all existing and future Senior Indebtedness of such Guarantor, if any.

Each payment to be made by a Guarantor in respect of its Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such 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 Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect

-103-

to such maximum amount and all other contingent and fixed liabilities of such 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 Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all guaranteed obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

To evidence its Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by its president, one of its vice presidents, one of its managers, one of its members, one of its general partners, one of its executives, or its corporate treasurer or controller corporate staff.

Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

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

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

If required by Section 4.15 hereof, the Issuers shall cause any newly created or acquired Restricted Subsidiary to comply with the provisions of Section 4.15 hereof and this Article 10, to the extent applicable.

Each Guarantor shall be subrogated to all rights of Holders of Notes against the Issuers in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 10.01 hereof; provided that, if an Event of Default has occurred and is continuing, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuers under this Indenture or the Notes shall have been paid in full.

Each 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 Guarantee are knowingly made in contemplation of such benefits.

A Guarantee by a Guarantor shall be automatically and unconditionally released and discharged, and no further action by such Guarantor, the Issuers or the Trustee is required for the release of such Guarantor’s Guarantee, upon:

(1) (A) any sale, exchange or transfer (by merger or otherwise) of the Capital Stock of such Guarantor (other than VNU HF) (including any sale, exchange or transfer), after which the applicable Guarantor is no longer a Restricted Subsidiary or all or substantially all the assets of such Guarantor (other than VNU HF) which sale, exchange or transfer is made in compliance with the applicable provisions of this Indenture;

-104-

(B) the release or discharge of the guarantee by such Guarantor (other than VNU HF) of the Senior Credit Facilities or the guarantee which resulted in the creation of such Guarantee, except a discharge or release by or as a result of payment under such guarantee;

(C) the proper designation of any Restricted Subsidiary that is a Guarantor (other than VNU HF) as an Unrestricted Subsidiary; or

(D) the Issuers exercising their Legal Defeasance option or Covenant Defeasance option in accordance with Article 8 hereof or the Issuers’ obligations under this Indenture being discharged in accordance with the terms of this Indenture; and

(2) such Guarantor delivering to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in this Indenture relating to such transaction have been complied with.

Notwithstanding anything herein to the contrary, any obligation, guarantee or undertaking granted or assumed by a Person incorporated under the laws of The Netherlands or by a Person incorporated under the laws of Ireland pursuant to this Indenture shall be deemed not to be undertaken or incurred by such Person to the extent that the same would constitute unlawful financial assistance within the meaning of Section 2.207(c) or 2.98(c) of the Dutch Civil Code or Section 60 of the Irish Companies Act 1963 (as amended) or any other applicable financial assistance rules under any relevant jurisdiction (the “ Prohibition ”) and the provisions of this Indenture and the other documents to be entered into in connection with Notes and the Guarantee shall be construed accordingly. For the avoidance of doubt it is expressly acknowledged that the relevant Persons incorporated under the laws of the Netherlands or the laws of Ireland will continue to guarantee and secure all such obligations which, if included, do not constitute a violation of the Prohibition.

ARTICLE 11

-105-

one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuers, and an Issuer or any Guarantor have irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

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

(C) the Issuers have paid or caused to be paid all sums payable by them under this Indenture; and

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

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 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 Issuers acting as their own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium and Additional Interest, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 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 Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuers have made any payment of principal of, premium and Additional Interest, if any, or interest on any Notes because of the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.
