(1) if the transaction giving rise to the need to calculate the Consolidated Leverage Ratio is an Incurrence of Indebtedness, the amount of such Indebtedness shall be calculated after giving effect on a pro forma basis to such Indebtedness;

(2) if the Company or any Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged any Indebtedness that was outstanding as of the end of the Reference Period, or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged on the date of the transaction giving rise to the need to calculate the Consolidated Leverage Ratio (other than, in each case, Indebtedness Incurred under any revolving credit agreement), the aggregate amount of Indebtedness shall be calculated on a pro forma basis, after giving effect to such repayment, repurchase, defeasement or discharge;

(3) if since the beginning of the Reference Period the Company or any Restricted Subsidiary shall have made any Asset Sale, the Consolidated Cash Flow for the Reference Period shall be reduced by an amount equal to the Consolidated Cash Flow (if positive) directly attributable to the assets which are the subject of such Asset Sale for the Reference Period or increased by an amount equal to the Consolidated Cash Flow (if negative) directly attributable thereto for the Reference Period;

(4) if since the beginning of the Reference Period the Company or any Restricted Subsidiary (by merger or otherwise) shall have made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary) or other acquisition of assets which constitutes all or substantially all of an operating unit of a business, Consolidated Cash Flow for the Reference Period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of the Reference Period; and

(5) if since the beginning of the Reference Period any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such Reference Period) shall have made any Asset Sale, any Investment or acquisition of assets that would have required an adjustment pursuant to clause (3) or (4) above if made by the Company or a Restricted Subsidiary during the Reference Period, Consolidated Cash Flow for the Reference Period shall be calculated after giving pro forma effect thereto as if such Asset Sale, Investment or acquisition had occurred on the first day of the Reference Period.

For purposes of this definition, whenever pro forma effect is to be given to an acquisition or disposition of assets, such pro forma calculation shall be made in good faith by a responsible financial or accounting officer of the Company. Any such pro forma calculation may include adjustments appropriate, in the reasonable determination of the Company, as set forth in an Officer’s Certificate, to reflect operating expense reductions and other operating improvements or synergies reasonably expected to result from any acquisition or disposition or operational change to the extent such adjustments, without duplication, continue to be applicable to the relevant four-quarter period; provided that (x) such operating expense reductions and other operating improvements or synergies are reasonably identifiable and factually supportable and (y) such actions are reasonably expected to be taken no later than 12 months after the relevant transaction.

For purposes of this definition, in calculating the Consolidated Cash Flow and the aggregate amount of Indebtedness of the Company and its Restricted Subsidiaries, the Consolidated Cash Flow and Indebtedness attributable to discontinued operations will be excluded.

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 date of determination had been the applicable rate for the entire period (taking into account any interest rate swap agreement, interest rate cap agreement or other financial agreement or arrangement with respect to exposure to interest rates applicable to such Indebtedness if such interest rate agreement has a remaining term in excess of twelve months).

If any Indebtedness is Incurred under a revolving credit facility and is being given pro forma effect, the interest on such Indebtedness shall be calculated based on the average daily balance of such Indebtedness for the four quarters subject to the pro forma calculation to the extent such Indebtedness was Incurred for working capital purposes.

“Consolidated Net Income” means, for any period, the aggregate of the net income (loss) of the Company and the Restricted Subsidiaries for such period, on a consolidated basis, determined in accordance with GAAP; provided that:

(1) the net income (loss) of any Person that is not a Restricted Subsidiary or that is accounted for by the equity method of accounting will be included only to the extent of the amount of dividends or distributions paid in cash to the Company or a Restricted Subsidiary;

(2) the net income (but not the net loss) of any Restricted Subsidiary will be excluded to the extent that the declaration or payment of dividends or similar distributions by that Restricted Subsidiary of that net income is not at the date of determination permitted without any prior governmental approval (that has not been obtained) or, directly or indirectly, by 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 equityholders;

(3) the net income (loss) of any Person acquired during the specified period for any period prior to the date of such acquisition will be excluded;

(4) the net income (loss) of any Person that is not a Restricted Subsidiary on a consolidated basis allocable to minority interests in unconsolidated Persons or Unrestricted Subsidiaries to the extent that cash dividends or distributions have not actually been received by such a Person or one of its consolidated Restricted Subsidiaries will be excluded;

(5) any gain or loss, together with any related provision for taxes on such gain or loss, realized in connection with: (a) any sale of assets outside the ordinary course of business of the Company; or (b) the disposition of any securities by the Company or a Restricted Subsidiary or the extinguishment of any Indebtedness of the Company or any Restricted Subsidiary, will be excluded;

(6) any extraordinary gain or loss, together with any related provision for taxes on such extraordinary gain or loss, will be excluded;

(7) any non-cash compensation expense realized for grants of restricted stock, performance shares, stock options or other rights with respect to equity to officers, directors and employees of the Company and any Restricted Subsidiary; provided that such shares, options or other rights can be redeemed at the option of the holder only for Capital Stock (other than Disqualified Stock of the Company); and

Each Global Note shall represent such of the outstanding Notes as shall be specified in the “Schedule of Exchanges of Interests in the Global Note” attached thereto and each shall provide that it shall represent up to the aggregate principal amount of Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as applicable, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06.

(c) Temporary Global Notes. Notes offered and sold in reliance on Regulation S shall be issued initially in the form of the Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Notes Custodian and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and authenticated by the Trustee as hereinafter provided.

(i) During the Restricted Period, beneficial ownership interests in Regulation S Temporary Global Notes may only be sold, pledged or transferred (A) to the Company, (B) in an offshore transaction in accordance with Rule 904 of Regulation S (other than a transaction resulting in an exchange for an interest in a Regulation S Permanent Global Note) or (C) pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities laws of any State of the United States; and beneficial interests in a 144A Global Note may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Note, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if applicable).

(ii) Within a reasonable period after expiration or termination of the Restricted Period, beneficial interests in each Regulation S Temporary Global Note shall be exchanged for beneficial interests in a Regulation S Permanent Global Note upon delivery to DTC of the certification of compliance and the transfer of applicable Notes pursuant to the Applicable Procedures. Simultaneously with the authentication of the corresponding Regulation S Permanent Global Note, the Trustee shall cancel the corresponding Regulation S Temporary Global Note.

(iii) Notwithstanding anything to the contrary in Section 2.06, a beneficial interest in the Regulation S Temporary Global Note may not be exchanged for a Definitive Note or transferred to a Person who takes delivery thereof in the form of a Definitive Note prior to (X) the expiration of the Restricted Period and (Y) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) of the Securities Act, except in the case of a transfer pursuant to an exemption from the registration requirements of the Securities Act other than Rule 903 or Rule 904.

(d) Terms. The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is unlimited.

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

The Notes shall be subject to repurchase by the Company pursuant to an offer as provided in Section 4.07 or Section 4.09. The Notes shall not be redeemable, other than as provided in Article 3.

Additional Notes ranking pari passu with the Initial Notes may be created and issued from time to time by the Company without notice to or consent of the Holders and shall be consolidated with and form a single class with the Initial Notes and shall have the same terms as to status, redemption or otherwise (other than with respect to the purchase price thereof and the date from which the interest accrues) as the Initial Notes; provided that the Company’s ability to issue Additional Notes shall be subject to the Company’s compliance with Section 4.03 and Section 4.06. The Notes and any Additional Notes shall be substantially identical other than the issuance dates, offering price, transfer restrictions and, if applicable, the date from which interest shall accrue. The Additional Notes shall be secured, equally and ratably with the Notes and any Permitted Additional Pari Passu Obligations, by a Lien on the Collateral. Except as described under Article 9, the Initial Notes and any Additional Notes subsequently issued under this Indenture will be treated as a single class for all purposes under this Indenture, including waivers, amendments, redemptions and offers to purchase. Unless the context requires otherwise, references to “Notes” for all purposes of this Indenture include any Additional Notes that are actually issued. Any Additional Notes shall be issued with the benefit of an indenture supplemental to this Indenture.

(e) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream shall be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Note that are held by Participants through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

At least one Officer shall execute the Notes on behalf of the Company by manual or facsimile signature.

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

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 provided for in Exhibit A attached hereto, by the manual 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 the Company’s order (an “Authentication Order”) signed by one Officer, authenticate and deliver the Initial Notes. In addition, subject to the terms of this Indenture, at any time, from time to time, the Trustee shall upon receipt of an Authentication Order authenticate and deliver any Additional Notes in an aggregate principal amount to be determined at the time of issuance specified therein.

Such Authentication Order shall specify the amount of the Notes to be authenticated and, in the case of any issuance of Additional Notes pursuant to Section 2.01, shall certify that such issuance is in compliance with Section 4.03 and Section 4.06.

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

Section 2.03 Registrar and Paying Agent.

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

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

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

Section 2.04 Paying Agent to Hold Money in Trust.

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

Section 2.05 Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Registrar, the Company 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 Company 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. 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.

(iii) [Intentionally Omitted]

(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 Company, 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) Neither the Registrar nor the Company shall 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 mailing of notice of redemption of Notes for redemption under Section 3.02 and ending at the close of business on the day of such mailing, (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 Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

(vii) Upon surrender for registration of transfer of any Note at the office or agency of the Company designated pursuant to Section 2.03, the Company shall execute, and the Trustee shall, upon receipt of an Authentication Order, 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.

respect to any transfer of any interest in any Note (including transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(i) Automatic Exchange from Restricted Global Note to Unrestricted Global Note. At the option of the Company and upon compliance with the following procedures, beneficial interests in a Restricted Global Note shall be exchanged for beneficial interests in an Unrestricted Global Note. In order to effect such exchange, the Company shall provide written notice to the Trustee and the Company shall (i) direct the Depositary to transfer the specified amount of the outstanding beneficial interests in a particular Restricted Global Note to an Unrestricted Global Note and provide the Depositary with all such information as is necessary for the Depositary to appropriately credit and debit the relevant Holder accounts and (ii) provide prior written notice to all Holders of such exchange, which notice must include the date such exchange is proposed to occur, the CUSIP number of the relevant Restricted Global Note and the CUSIP number of the Unrestricted Global Note into which such Holders’ beneficial interests will be exchanged.

The Company may request from Holders such information it reasonably determines is required in order to be able to deliver such Officer’s Certificate and Opinion of Counsel. Upon such exchange of beneficial interests pursuant to this Section 2.06(i), the Registrar shall reflect on its books and records the date of such transfer and a decrease and increase, respectively, in the principal amount of the applicable Restricted Global Note and the Unrestricted Global Note, respectively, equal to the principal amount of beneficial interests transferred. Following any such transfer pursuant to this Section 2.06(i) of all of the beneficial interests in a Restricted Global Note, such Restricted Global Note shall be canceled.

Section 2.07 Replacement Notes.

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

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

Section 2.08 Outstanding Notes.

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

If a Note is replaced pursuant to Section 2.07, 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, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a Redemption Date or maturity date, money sufficient to pay 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.

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent (other than in respect of any action pursuant to the second paragraph under Section 9.02, which requires the consent of each Holder of an affected Note), Notes owned by the Company, or by any Affiliate of the Company, 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 actually 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 the Company or any obligor upon the Notes or any Affiliate of the Company or of such other obligor.

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Company 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 Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes shall be entitled to all of the benefits accorded to Holders of Notes under this Indenture.

Section 2.11 Cancellation.

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall, at the written direction of the Company, cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of such canceled Notes in accordance with its customary procedures. Certification of the cancellation of all cancelled Notes shall be delivered to the Company upon written request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Company defaults in a payment of interest on the Notes, it 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 on a subsequent special record date, in each case at the rate provided in the Notes. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit 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 Company 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. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed, first-class postage prepaid, to each Holder a notice (which shall be prepared by the Company) 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.

Section 2.13 CUSIP and ISIN Numbers.

The Company in issuing the Notes may use CUSIP and/or ISIN numbers (if then generally in use) and, if so, the Trustee shall use CUSIP and/or ISIN 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 Company will as promptly as practicable notify the Trustee in writing of any change in the CUSIP or ISIN numbers.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select Notes for redemption or purchase as follows (a) in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed, which requirements shall be specified in writing by the Company to the Trustee; or (b) if the Notes are not so listed, on a pro rata basis, by lot or by such other method as the Trustee deems fair and appropriate. In the event of partial redemption or purchase, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the Redemption Date by the Registrar and Paying Agent from the outstanding Notes not previously called for redemption or purchase.

The Registrar and Paying Agent shall promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes redeemed in part shall be redeemed only in integral multiples of $1,000, and no Notes of $2,000 or less shall be redeemed in part, except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not $2,000 or a multiple of $1,000 in excess thereof, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03 Notice of Redemption.

The Company shall mail or cause to be mailed by first-class mail (or sent electronically) notices of redemption at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such Holder’s registered address or otherwise in accordance with the procedures of the Depository, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with Article 8 or Article 14. In connection with any redemption of Notes, any such redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the

Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed.

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

(a) the Redemption Date;

(b) the redemption price;

(c) if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed and that, after the Redemption Date upon surrender of such Note (other than Global Notes), a new Note or Notes in principal amount equal to the unredeemed portion of the original Note representing the same indebtedness to the extent not redeemed will be issued in the name of the Holder of the Notes upon cancellation of the original Note;

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

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

(f) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the Redemption Date;

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

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

At the Company’s request, the Trustee shall give the notice of redemption in the name of the Company and at the Company’s expense; provided that the Company shall have delivered to the Trustee, at least 5 Business Days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to this Section 3.03 (unless a shorter notice shall be agreed to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and a copy of the notice containing the information required in the preceding paragraph.

The Company shall deliver written notice to the Trustee setting forth the calculation of the Make-Whole Amount, if any, on or prior to the date a notice of redemption is given and the Trustee may conclusively rely on such calculation without further investigation.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price, subject to the satisfaction of any conditions precedent. The notice, if mailed (or sent electronically) in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail (or electronically) 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. Subject to Section 3.05, on and after the Redemption Date, interest ceases to accrue on Notes or portions thereof called for redemption unless the Company defaults in the delivery of the redemption payment.

Section 3.05 Deposit of Redemption or Purchase Price.

Prior to 10:00 a.m. (New York City time) on the redemption or purchase date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued

and unpaid interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued and unpaid interest on, all Notes to be redeemed or purchased.

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

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Note (other than a Global Note) that is redeemed or purchased in part, the Company shall issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered representing the same indebtedness to the extent not redeemed or purchased; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. It is understood that, notwithstanding anything in this Indenture to the contrary, only an Authentication Order and not an Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate such new Note.

Section 3.07 Optional Redemption.

(a) Prior to December 1, 2021, the Company may redeem the Notes, in whole or from time to time in part, at a redemption price equal to the sum of (i) 100% of the principal amount thereof, plus (ii) the Make-Whole Amount, if any, plus (iii) accrued and unpaid interest thereon, to but not including the date of redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date.

(b) At any time on or after December 1, 2021, the Company may redeem the Notes, in whole or in part, at a redemption price equal to the sum of (i) 100% of the principal amount thereof, plus (ii) accrued and unpaid interest thereon, to but not including the date of redemption.

Section 4.03 Limitation on Indebtedness, Disqualified Stock and Preferred Stock.

(a) The Company will not, and will not permit any Restricted Subsidiary to, Incur any Indebtedness or issue shares of Disqualified Stock; provided that the Company or any Guarantor may Incur Indebtedness or issue shares of Disqualified Stock or shares of Preferred Stock if, after giving effect to the Incurrence of such Indebtedness, or the issuance of such Disqualified Stock or Preferred Stock, as the case may be, and the receipt and application of the proceeds therefrom, the Consolidated Leverage Ratio would be positive and less than 5.0 to 1.

(b) Section 4.03(a) will not prohibit the Incurrence of any of the following (collectively, “Permitted Indebtedness”):

(b) any event that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary (except for any pledge of such Indebtedness constituting a Permitted Lien until the pledgee commences actions to foreclose on such Indebtedness) will be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) (i) the Guarantee by the Company or any Guarantor of Indebtedness of the Company or a Restricted Subsidiary and (ii) the Guarantee by a non-Guarantor Restricted Subsidiary of Indebtedness of another non-Guarantor Restricted Subsidiary, in each case, that was permitted to be Incurred by another provision of this Section 4.03;

(8) the Incurrence by the Company or any Guarantor of Hedging Obligations that are Incurred for the purpose of fixing, hedging or swapping interest rate, commodity price or foreign currency exchange rate risk (or to reverse or amend any such agreements previously made for such purposes), and not for speculative purposes;

(10) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness in respect of bid, performance or surety bonds or letters of credit issued in the ordinary course of business, including letters of credit supporting lease obligations or supporting such bid, performance or surety bonds or in respect of workers’ compensation claims, health, disability or other employee benefits (whether current or former) or property, casualty or liability insurance or self-insurance, or other Indebtedness with respect to reimbursement obligations regarding workers’ compensation claims; provided that, upon the drawing of such letters of credit or the Incurrence of such repayment or reimbursement obligations under any such bid, performance or surety bonds, such obligations are reimbursed within 30 days following such drawing or Incurrence;

(11) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness to the extent the net cash proceeds thereof are promptly deposited pursuant to Sections 8.02, 8.03 or 14.01;

(12) customer deposits and advance payments received from customers for goods and services sold in the ordinary course of business;

(13) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness (including Capital Lease Obligations) represented by an IRU which is entered into in the ordinary course of business;

(14) the Incurrence by the Company or any Restricted Subsidiary of additional Indebtedness in an aggregate amount at any one time outstanding pursuant to this clause (14), not to exceed $25 million, provided that the principal amount of Indebtedness Incurred by any Restricted Subsidiary that is not a Guarantor pursuant to this clause (14) does not exceed $15 million at any one time outstanding;

(15) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business, provided that such Indebtedness is extinguished within five Business Days of its Incurrence;

(16) Indebtedness, Disqualified Stock or Preferred Stock (i) of the Company or any of its Restricted Subsidiaries Incurred to finance an acquisition and (ii) of Persons that are acquired by the Company or any of its Restricted Subsidiaries or merged into the Company or a Restricted Subsidiary in accordance with the terms of this Indenture; provided, however, that after giving effect to such acquisition and the Incurrence of such Indebtedness, Disqualified Stock or Preferred Stock, either:

(a) the Company would be permitted to Incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Leverage Ratio test set forth in Section 4.03(a); or

(b) the Consolidated Leverage Ratio would be less than immediately prior to such acquisition;

(17) Indebtedness owed on a short-term basis to banks and other financial institutions Incurred in the ordinary course of business of the Company and the Restricted Subsidiaries with such banks or financial institutions that arises in connection with ordinary banking arrangements to manage cash balances of the Company and the Restricted Subsidiaries;

(18) Indebtedness incurred by a Restricted Subsidiary in connection with bankers’ acceptances, discounted bills of exchange or the discounting or factoring of receivables for credit management purposes, in each case incurred or undertaken in the ordinary course of business on arm’s-length commercial terms;

(19) shares of Preferred Stock of a Restricted Subsidiary issued to the Company or another Restricted Subsidiary; provided that any subsequent issuance or transfer of any Capital Stock or any other event that results in any Restricted Subsidiary that holds such shares of Preferred Stock of another Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such shares of Preferred Stock (except to the Company or another Restricted Subsidiary) shall be deemed, in each case, to be an issuance of shares of Preferred Stock not permitted by this clause (19);

(20) Indebtedness Incurred by a Receivables Subsidiary in a Qualified Receivables Financing that is not recourse to the Company or any Restricted Subsidiary other than a Receivables Subsidiary (except for Standard Securitization Undertakings) in an amount, when taken together with all Indebtedness Incurred under clause (1) above, will not exceed $30 million at any one time outstanding; and

(21) customer deposits and advance payments received in the ordinary course of business from customers for goods purchased in the ordinary course of business.

(c) For purposes of determining compliance with this Section 4.03, in the event that an item of Indebtedness (or any portion thereof) meets the criteria of more than one of the categories described in clauses (1) through (21) of Section 4.03(b) or is entitled to be Incurred pursuant to Section 4.03(a), the Company shall, in its sole discretion, at the time of Incurrence, divide, classify or reclassify, or at any later time divide, classify or reclassify, such item of Indebtedness (or any portion thereof) in any manner that complies with this covenant. Accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms, the payment of dividends on Disqualified Stock or Preferred Stock in the form of additional shares of Disqualified Stock or Preferred Stock of the same class, the accretion of liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 4.03. Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness that are otherwise included in the determination of a particular amount of Indebtedness shall not be included in the determination of such amount of Indebtedness, provided that the Incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in compliance with this Section 4.03.

(d) For purposes of determining compliance with this covenant, (x) all Preferred Stock issued by a Subsidiary of such Person shall be valued at the greater of its voluntary or involuntary liquidation preference and its maximum fixed repurchase price plus accrued dividends and (y) all Disqualified Stock issued by such Person shall be valued at the greater of its voluntary or involuntary liquidation preference and its maximum fixed repurchase price plus accrued dividends. For purposes hereof, the “maximum fixed repurchase price” of any Disqualified Stock or Preferred Stock which does not have a fixed repurchase price will be calculated in accordance with the terms of such Disqualified Stock or Preferred Stock, as applicable, as if such Disqualified Stock or Preferred Stock were repurchased on any date on which Indebtedness will be required to be determined pursuant to this Indenture.

(e) 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 or first Incurred (whichever yields the lower U.S. dollar-equivalent), 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.

Section 4.04 Limitation on Restricted Payments.

(a) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, take any of the following actions (each, a “Restricted Payment”):

(i) declare or pay any dividend or make any other payment or distribution with respect to any of the Company’s or any Restricted Subsidiary’s Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any Restricted Subsidiary (other than dividends, payments or distributions (x) payable in Equity Interests (other than Disqualified Stock) of the Company or (y) to the Company or a Restricted Subsidiary));

(ii) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company or any Restricted Subsidiary) any Equity Interests of the Company;

(iii) call for redemption or make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, prior to the Stated Maturity thereof, any Subordinated Indebtedness except (a) in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such payment, purchase or other acquisition or (b) intercompany Indebtedness permitted to be Incurred pursuant to Section 4.03(b)(6); or

(iv) make any Investment (other than a Permitted Investment);

unless, at the time of and after giving pro forma effect to such Restricted Payment:

(1) no Default or Event of Default will have occurred and be continuing or would occur as a consequence thereof;

(2) the Company’s Consolidated Leverage Ratio would be positive and less than 4.25 to 1; and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and the Restricted Subsidiaries after January 26, 2011 (excluding

Restricted Payments permitted by clauses (2), (3), (4), (5) and (8) of Section 4.04(b)), is less than the sum, without duplication, of:

(a) (x) the aggregate Consolidated Cash Flow accrued in the period beginning on the first day of the quarter beginning on January 1, 2011, and ending on the last day of the most recent quarter for which internal financial statements are available prior to the date of such proposed Restricted Payment (or, if such Consolidated Cash Flow for such period is a deficit, less 100% of such deficit), less (y) 1.5 times consolidated interest expense during such period; plus

(b) 100% of the aggregate amount received by the Company in cash and the Fair Market Value of property other than cash since January 26, 2011 as a contribution to its common equity capital or from the issue or sale of Equity Interests (other than Disqualified Stock) of the Company or any Restricted Subsidiary and the amount of reduction of Indebtedness of the Company or its Restricted Subsidiaries that has been converted into or exchanged for such Equity Interests (other than Equity Interests sold to, or Indebtedness held by, a Subsidiary of the Company); plus

(c) with respect to Investments (other than Permitted Investments) made by the Company and the Restricted Subsidiaries after January 26, 2011, an amount equal to the net reduction in such Investments in any Person (except, in each case, to the extent any such amount is included in the calculation of Consolidated Net Income), resulting from repayment to the Company or any Restricted Subsidiary of loans or advances or from the receipt of net cash proceeds from the sale of any such Investment in an amount equal to 100% of the net cash proceeds or the Fair Market Value of the property other than cash, from the release of any Guarantee (except to the extent any amounts are paid under such Guarantee) or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries, not to exceed, in each case, the amount of such Investments previously made by the Company or any Restricted Subsidiary of such Person; plus

(d) the principal amount of any Indebtedness, or the liquidation preference or maximum fixed repurchase price, as the case may be, of any Disqualified Stock, of the Company or any Restricted Subsidiary thereof issued after January 26, 2011 (other than Indebtedness or Disqualified Stock issued to a Restricted Subsidiary or an employee stock ownership plan or trust established by the Company or any Restricted Subsidiary (other than to the extent such employee stock ownership plan or trust has been funded by the Company or any Restricted Subsidiary)) which has been converted into or exchanged for Equity Interests in the Company or any other direct or indirect parent of the Company (other than Disqualified Stock).

(b) The provisions of Section 4.04(a) shall not prohibit the following; provided that, in the case of clauses (7) and (8) below only, no Default has occurred and is continuing or would be caused thereby:

(1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of this Indenture, and the redemption of any Indebtedness that is subordinated in right of payment to the Notes or the Note Guarantees within 60 days after the date on which notice of such redemption was given, if at said date of the giving of such notice, such redemption would have complied with the provisions of this Indenture;

(2) the payment of any dividend by a Restricted Subsidiary to all the holders of its Common Stock on a pro rata basis;

(3) any Restricted Payment in exchange for, or out of the net cash proceeds of a contribution to the common equity of the Company or a substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests (other than Disqualified Stock) of the Company; provided that the amount of any such net cash proceeds that are utilized for such Restricted Payment will be excluded from Section 4.04(a)(3)(b);

(4) the redemption, repurchase, defeasance or other acquisition or retirement for value of Indebtedness that is subordinated in right of payment to the Notes or the Note Guarantees in exchange for or with the net cash proceeds from a substantially concurrent Incurrence (other than to a Subsidiary of the Company) of, Permitted Refinancing Indebtedness;

(5) the repurchase of Capital Stock deemed to occur upon the exercise of options or warrants to the extent that such Capital Stock represents all or a portion of the exercise price thereof and applicable withholding taxes, if any;

(6) the payment of cash in lieu of fractional Equity Interests pursuant to the exchange or conversion of any exchangeable or convertible securities; provided, that such payment shall not be for the purpose of evading the limitations of this covenant (as determined by the Board of Directors of the Company in good faith);

(7) the declaration and payment of dividends to holders of any class or series of Disqualified Stock of the Company or any Restricted Subsidiary, or Preferred Stock of a Restricted Subsidiary, in each case issued in accordance with Section 4.03;

(8) other Restricted Payments, together with any Restricted Payments made, divided, classified or reclassified under Section 4.04(b)(8) of the indenture governing the Existing Unsecured Notes to the extent such Restricted Payments are not made, divided, classified or reclassified pursuant to this clause 4.04(b)(8), in an aggregate amount not to exceed $150 million;

(9) purchases of receivables pursuant to a Receivables Repurchase Obligation in connection with a Qualified Receivables Financing and the payment or distribution of Receivables Fees;

(10) payments or distributions to satisfy dissenters’ rights, pursuant to or in connection with a consolidation, merger or transfer of assets that complies with the provisions of this Indenture applicable to mergers, consolidations and transfers of all or substantially all the property and assets of the Company;

(11) the purchase, retirement, redemption or other acquisition for value of Equity Interests of the Company held by any future, present or former employee, director or consultant of the Company or any Subsidiary of the Company (or their permitted transferees) pursuant to any management equity plan or stock option plan or any other management or employee benefit plan or other agreement or arrangement; provided, however, that the aggregate amounts paid under this clause (11) shall not exceed (x) $1.0 million in any calendar year, with unused amounts in any calendar year being permitted to be carried over for the next succeeding calendar year up to a maximum of $2.5 million in the aggregate in any calendar year; and

(12) for so long as the Company is a member of a group filing a consolidated, affiliated, unitary or combined tax return with its direct or indirect parent, payments with respect to such group’s consolidated, affiliated, unitary or combined income tax liability attributable to the Company and/or its Subsidiaries, in an amount not to exceed any such taxes that the Company and its Subsidiaries would have been required to pay on a separate group basis if the Company and such Subsidiaries had paid such taxes on a consolidated, affiliated, unitary or combined basis on behalf of an affiliated group consisting only of the Company and its Subsidiaries (reduced by any such income taxes paid or to be paid directly by the Company or its Subsidiaries); provided that any such tax payments attributable to any Unrestricted Subsidiaries shall not exceed any corresponding payments actually distributed by such Unrestricted Subsidiaries to the Company or any of its Restricted Subsidiaries.

(c) The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued to or by the Company or such Subsidiary, as the case may be, pursuant to the Restricted Payment.

(d) For purposes of this Section 4.04, if any Investment or Restricted Payment would be permitted pursuant to one or more provisions described above and/or one or more of the exceptions contained in the

definition of “Permitted Investments,” the Company may divide and classify such Investment or Restricted Payment in any manner that complies with this covenant and may later divide and reclassify any such Investment or Restricted Payment so long as the Investment or Restricted Payment (as so divided and/or reclassified) would be permitted to be made in reliance on the applicable exception as of the date of such reclassification.

Section 4.05 Limitation on Transactions with Affiliates.

(a) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly 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, make, amend, renew or extend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any of their Affiliates (each, an “Affiliate Transaction”), unless:

(1) such Affiliate Transaction is on terms that are not less favorable, taken as a whole, in any material respect to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable arm’s-length transaction by the Company or such Restricted Subsidiary with an unrelated Person; and

(2) the Company delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $2.5 million, a Board Resolution set forth in an Officer’s Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with clause (a)(1) above and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the Disinterested Members.

(b) The following items will be deemed not to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.05(a):

(4) payments or loans (or cancellation of loans, advances or guarantees) or advances to employees or consultants or guarantees in respect thereof for bona fide business purposes in the ordinary course of business;

(6) (a) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture, which are fair to the Company and its Restricted Subsidiaries in the reasonable determination of the Board of Directors or the senior management of the Company, and are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party or (b) transactions with Unrestricted Subsidiaries in the ordinary course of business;

(7) the sale or issuance of Equity Interests (other than Disqualified Stock) of the Company;

(8) any contribution to the capital of the Company (other than Disqualified Stock);

Section 4.06 Limitation on Liens.

(a) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create, Incur or suffer to exist any Lien (other than Permitted Liens) on any asset or property of the Company or such Restricted Subsidiary, or any income or profits therefrom, or assign or convey any right to receive income therefrom, that secures any Obligations of the Company or such Restricted Subsidiary, unless (i) in the case of any asset or property not constituting, or required to be pledged as, Collateral pursuant to the terms of this Indenture, the Security Agreement and the mortgages, the Notes or the applicable Guarantee are equally and ratably secured with or prior to such Obligation with a Lien on the same assets of the Company or such Restricted Subsidiary, as the case may be, pursuant to appropriate security documentation and subject to the terms and provisions of the

Intercreditor Agreement and (ii) in the case of any asset or property constituting, or required to be pledged as, Collateral pursuant to the terms of this Indenture, the Security Agreement and the mortgages, after giving pro forma effect thereto and to the Incurrence of related Indebtedness and the use of proceeds therefrom, the Secured Leverage Ratio is positive and less than 3.5 to 1 and Obligations secured by such Lien constitute Additional Obligations subject to the terms of the Intercreditor Agreement (it being understood Additional Notes shall only be issued in compliance with the terms of this clause (ii)).

(b) Section 4.06(a)(i) shall not require the Company or any Restricted Subsidiary of the Company to secure the Notes if the relevant Lien consists of a Permitted Lien. Any Lien which is granted to secure the Notes or such Guarantee under Section 4.06(a)(i) shall be automatically released and discharged at the same time as the release of the Lien (other than a release following enforcement of remedies in respect of such Lien or the Obligations secured by such Lien) that gave rise to the obligation to secure the Notes or such Guarantee under Section 4.06(a).

Section 4.07 Limitation on Sale of Assets.

(a) The Company will not, and will not permit any Restricted Subsidiary to, consummate an Asset Sale unless:

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of;

(2) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of:

(a) Cash Equivalents (including any Cash Equivalents received from the conversion within 90 days of such Asset Sale of any securities, notes or other obligations received in consideration of such Asset Sale);

(b) Replacement Assets; or

(3) in the case of an Asset Sale of Collateral, all consideration from such Asset Sale that is not in the form of Cash Equivalents is pledged as Collateral to secure the Notes concurrently with or immediately after the receipt thereof.

(b) Any Net Available Cash received by the Company or any Restricted Subsidiary from any Asset Sale in the case of any Asset Sale (A) (x) shall be reinvested within 365 days in Replacement Assets and (y) the purchase of the Replacement Assets that shall be pledged as Collateral to the extent otherwise required by this Indenture and the Security Documents is consummated no later than (i) the 365th day after such Asset Sale or (ii) so long as a binding agreement with respect to the purchase of Replacement Assets is entered into within 365 days after the Asset Sale, 90 days after the date of such binding agreement, or (B) shall otherwise be used to make an Offer to Purchase (as described below) in accordance with the following paragraph. To the extent the Company or any Restricted Subsidiary consummates an Asset Sale of Equity Interests of a Restricted Subsidiary or all of or substantially all of the assets of a Restricted Subsidiary or of a division or line of business of the Company and the Restricted Subsidiary for consideration in excess of $20.0 million, any Net Available Cash received from such an Asset Sale shall be held in trust as Collateral in an Asset Sale Proceeds Account, for the benefit of the Holders of the Notes, for application in accordance with this Section 4.07.

(c) The amount of such Net Available Cash required to be applied (or to be committed to be applied) during such 365 day period as set forth in Section 4.07(b) and not applied (or committed to be applied) as so required by the end of such period shall constitute “Excess Proceeds.” If, as of the first day of any calendar month, the aggregate amount of Excess Proceeds totals at least $20 million, the Company must commence, not later than

the 15th Business Day of such month, and consummate an Offer to Purchase, from the Holders and all holders of other Pari Passu Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase with the proceeds of sales of assets, the maximum principal amount of Notes and such other Pari Passu Debt that may be purchased out of the Excess Proceeds. The offer price in any such Offer to Purchase will be equal to 100% of the principal amount (or accreted value, if applicable) of the Notes and such other Pari Passu Debt plus accrued and unpaid interest thereon to, but excluding, the date of purchase, subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant interest payment date falling prior to or on the repurchase date, and will be payable in cash. To the extent that any Excess Proceeds remain after consummation of an Offer to Purchase pursuant to this Section 4.07, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture, and those Excess Proceeds shall no longer constitute “Excess Proceeds.” If the aggregate principal amount of Notes and Pari Passu Debt tendered or otherwise surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes (and the Company or its agents shall select such Pari Passu Debt) to be purchased in the manner described below in Section 4.08(d).

(d) If more Notes are tendered pursuant to an Offer to Purchase than the Company is required to purchase, selection of such Notes for purchase will be made in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed (so long as the Trustee knows of such listing) or if such Notes are not listed, on a pro rata basis (with adjustments so that only Notes in denominations of the minimum denomination of $2,000 or integral multiples of $1,000 in excess thereof shall be purchased), by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that the selection of Notes for purchase shall not result in a Holder with a principal amount of Notes less than the minimum denomination of $2,000. No Note will be repurchased in part if less than the minimum denomination of such Note would be left outstanding.

(e) Except in the case of an Asset Sale of Collateral, for the purposes of this Section 4.07, the following are deemed to be Cash Equivalents: the assumption of (i) Indebtedness of the Company (other than Disqualified Stock or Indebtedness that is by its terms subordinated in right of payment to the Notes) or (ii) Indebtedness of any Restricted Subsidiary (other than Indebtedness of a Guarantor that is by its terms subordinated in right of payment to the Notes or Disqualified Stock of any Guarantor), and, in each case, the full and unconditional release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Sale.

Section 4.08 Future Subsidiary Note Guarantees.

If the Company or any Restricted Subsidiary acquires, creates or becomes a Material Domestic Subsidiary on or after the Issue Date, then that newly acquired or created Material Domestic Subsidiary must become a Guarantor and (a) execute a supplemental indenture substantially in the form of Exhibit E hereto, (b) execute supplements to the applicable Security Documents in order to xxxxx x Xxxx in the Collateral owned by such entity to the same extent as that set forth in this Indenture and the Security Documents and (c) take all actions required by the Security Documents to perfect such Lien.

Section 4.09 Purchase of Notes upon a Change of Control Triggering Event.

(a) Unless the Company has previously or concurrently mailed an unconditional redemption notice (except in connection with the occurrence of a Change of Control Triggering Event, such redemption notice may be conditional) with respect to all the outstanding Notes as described in Section 3.03, the Company must commence, within 30 days of the occurrence of a Change of Control Triggering Event, and consummate an Offer to Purchase for all Notes then outstanding, at a purchase price in cash equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest thereon, to, but excluding, the date of repurchase, subject to the rights of Holders of Notes, on the relevant record date to receive interest due on the relevant interest payment date falling on or prior to the repurchase date.

(b) The Company will not be required to make an Offer to Purchase upon a Change of Control Triggering Event if a third party makes the Offer to Purchase in the manner, at the times and otherwise in

compliance with the requirements set forth in this Indenture applicable to an Offer to Purchase made by the Company and purchases all Notes validly tendered and not withdrawn under such Offer to Purchase.

Section 4.10 Limitation on Sale and Leaseback Transactions.

The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction; provided that the Company or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction with respect to assets or properties other than Collateral if:

If, at any time, any Unrestricted Subsidiary would fail to meet any of the preceding requirements described in clause (4) above, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture, and any Indebtedness, Investments, or Liens on the property, of such Subsidiary will be deemed to be Incurred or made by a Restricted Subsidiary as of such date, and if such Indebtedness, Investments or Liens are not permitted to be Incurred or made as of such date under this Indenture, the Company will be in default under this Indenture.

(b) The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that:

(b) In the event that the Company is not required to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Company will nevertheless deliver such Exchange Act information to the Trustee and the Holders of the Notes as if the Company were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act (1) in the case of quarterly reports, within 15 days after

the time period specified in the SEC’s rules and regulations and (2) in the case of annual reports, within 30 days after the time period specified in the SEC’s rules and regulations. The posting of such reports, documents and information to the SEC’s or the Company’s website shall constitute delivery of such information to the Trustee and the Holders of Notes. In addition, in the event the Company and Cogent Holdco are not required to file reports under Section 13 or 15(d) of the Exchange Act, the Company will hold a quarterly conference call with Holders, qualified prospective investors and securities analysts to discuss the information contained in the annual and quarterly reports required hereunder not later than ten business days following the time the Company furnishes such reports to the Trustee.

(c) If the Company has designated as Unrestricted Subsidiaries any of its Subsidiaries that is a Significant Subsidiary or that, when taken together with all other Unrestricted Subsidiaries, would be a Significant Subsidiary, then the quarterly and annual financial information required by this Section 4.13 will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and the Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries.

(d) So long as any Notes remain outstanding the Company and the Guarantors shall furnish to the Holders and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(e) Notwithstanding the foregoing clauses (a) through (d), for so long as the Company is a wholly owned Subsidiary of Cogent Holdco and Cogent Holdco provides a Note Guarantee, the financial statements referred to above may be the financial statements of Cogent Holdco or Subsidiary so long as reasonably detailed information is provided showing the assets, liabilities, and operating results that are not attributable to the Company and its Subsidiaries.

(f) The Company will be deemed to have satisfied the information and reporting requirements of Section 4.13(a) with respect to the Holders if (a) the Company or a Subsidiary or a direct or indirect parent has filed such reports containing such information (including the information required pursuant to Section 4.13(e), which, for the avoidance of doubt, need not be filed with the SEC via XXXXX to the extent it is otherwise provided to Holders pursuant to this Section 4.13) with the SEC via the XXXXX (or successor) filing system or (b) the Company or such Subsidiary or such parent has made such reports available electronically (including by posting to a non-public, password-protected website as provided above) pursuant to this Section 4.13.

Section 4.14 Statement by Officers as to Default.

(a) The Company will deliver to the Trustee, on or before a date not more than 120 days after the end of each fiscal year of the Company (which fiscal year ends on December 31) after the Issue Date, an Officer’s Certificate, as to compliance herewith, including whether or not, after a review of the activities of the Company during such year and of the Company’s and each Guarantor’s performance under this Indenture, to the best knowledge of the signer on behalf of the Company, based on such review of the signer thereof, the Company and each Guarantor are in compliance with all conditions and covenants under this Indenture and is or is not in default in the performance and observance of any of the terms, provisions and conditions of this Indenture and, if there has been a Default specifying each Default and the nature and status thereof and any actions being taken by the Company and the Guarantors with respect thereto.

(b) When any Default or Event of Default has occurred and is continuing, the Company shall deliver to the Trustee by registered or certified mail or facsimile transmission of an Officer’s Certificate specifying such

Section 4.15 Maintenance of Insurance.

(a) At all times, at their own expense, the Company shall cause to be carried and maintained by all the Grantors with reputable insurers, insurance of the kinds and in the amounts and with deductibles as are customarily maintained by prudent businesses in similar circumstances, carrying on similar businesses or having comparable properties.

(b) The Collateral Agent shall be named as an additional insured or loss payee, as applicable, with respect to all insurance maintained by the Grantors on the Collateral and evidence of the same shall be provided to the Collateral Agent.

Any failure on the part of the Collateral Agent, the Trustee or the Holders to pursue or obtain the evidence of insurance required by this Section 4.15 from the Company or the other Grantors and/or failure of the Collateral Agent, the Trustee or Holders to point out any non-compliance of such evidence of insurance shall not constitute a waiver of any of the insurance requirements in this Section 4.15.

(d) During the existence and continuation of an Event of Default, all insurance proceeds or condemnation proceeds received by the Company or any of the Grantors in respect of any Collateral shall, if so directed by the Collateral Agent, be held in the Collateral Account held by the Collateral Agent for the benefit of the Holders pending application of such proceeds as permitted by this Indenture, the Intercreditor Agreement and the other Security Documents.

Section 4.16 Maintenance of Properties.

The Company will and each of the Guarantors (other than Cogent Holdco) will maintain or cause to be maintained in the ordinary course of business in good repair, working order and condition, normal wear and tear and disposal of obsolete equipment and fire, casualty or condemnation excepted, all properties used or useful in its business (whether owned or held under lease), and from time to time make or cause to be made all needed and appropriate repairs, renewals, replacements, additions, betterments, and improvements thereto, except where the failure to do so could not reasonably be expected to have a material adverse effect.

If an Event of Default (other than as specified in Section 6.01(a)(8) or (9)) shall occur and be continuing with respect to this Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all unpaid principal of, premium, if any, and accrued interest on all Notes to be due and payable immediately, by a notice in writing to the Company (with a copy to the Trustee if given by the Holders of the Notes) and upon any such declaration, such principal, premium, if any, and interest shall become due and payable immediately. If an Event of Default specified in Section 6.01(a)(8) or (9) occurs and is continuing, then all the Notes shall become due and payable immediately in an amount equal to the principal amount of the Notes, together with accrued and unpaid interest, if any, to the date the Notes become due and payable, without any declaration or other act on the part of the Trustee or any Holder.

Section 6.03 Other Remedies.

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, this Indenture or any Security Document.

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.

Section 6.04 Waiver of Past Defaults.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes waive, rescind or cancel any existing Default or Event of Default and its consequences hereunder if such waiver, rescission or cancellation would not conflict with any judgment or decree, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on the Notes (including in connection with an offer to purchase); provided, however, 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, rescission or cancellation shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Subject to the terms of the Intercreditor Agreement, the Security Documents and provision of an indemnity satisfactory to the Trustee, the Holders of a majority in aggregate principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or the Collateral Agent or exercising any trust power conferred on it. However, the Trustee and the Collateral Agent may refuse to follow any direction that conflicts with law, the Intercreditor Agreement, any other Security Document or this Indenture, that may involve the Trustee’s or the Collateral Agent’s personal liability, or that the Trustee or the Collateral Agent determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from Holders of Notes.

Section 6.06 Limitation on Suits.

Subject to Section 6.07, a Holder may not pursue any remedy with respect to this Indenture or the Notes unless: (1) the Holder gives the Trustee written notice of a continuing Event of Default; (2) the Holders of at least

25% in aggregate principal amount of outstanding Notes make a written request to the Trustee to pursue the remedy; (3) such Holder or Holders offer the Trustee indemnity reasonably satisfactory to the Trustee against any costs, liability or expense; (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and (5) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a written direction that is inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain preference or priority over another Holder of a Note.

Notwithstanding the foregoing, in no event may any Holder of Notes directly enforce any Lien of the Collateral Agent pursuant to the Security Documents.

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer pursuant to Section 4.07 or Section 4.09), 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; provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(a)(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, 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 compensation, reasonable expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceedings or any other proceedings, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies hereunder of the Trustee and the Holders shall continue as though no such proceeding has been instituted.

Section 6.10 Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.11 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders

may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.12 Trustee May File Proofs of Claim.

Subject to the Intercreditor Agreement, 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 compensation, reasonable 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 Company (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. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 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.

Section 6.13 Priorities.

Subject to the Security Documents and the Intercreditor Agreement, if any, if the Trustee collects any money or property pursuant to this Article 6 (including any amounts received from the Collateral Agent), it shall pay out the money or property in the following order:

(i) to the Trustee, Paying Agent, Registrar, Transfer Agent, their agents and attorneys for amounts due under Section 7.07, including payment of all compensation, expenses, fees, costs and liabilities incurred, and all advances made, by the Trustee, Paying Agent, Registrar or Transfer 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 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 interest, respectively; and

(iii) to the Company 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.

Section 6.14 Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable 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, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

ARTICLE 7

Section 7.01 Duties of 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.

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

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.

Section 7.04 Trustee’s Disclaimer.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Security Documents or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s 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.

Section 7.05 Notice of Defaults.

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. The receipt of reports, information and documents delivered to the Trustee pursuant to Section 4.13 shall not constitute actual knowledge or the receipt of written notice of any Default on the part of the Trustee.

Section 7.06 Reports by Trustee to Holders of the Notes.

Within 60 days after each January 15, beginning with the January 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 the Company 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 Company shall promptly notify the Trustee in writing when, if applicable, the Notes are listed on any stock exchange and of any delisting thereof.

Section 7.07 Compensation and Indemnity.

The Company and the Guarantors, jointly and severally, shall pay to the Trustee and the Collateral Agent 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 Company and the Guarantors, jointly and severally, shall reimburse the Trustee and the Collateral Agent 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 and Collateral Agent’s agents and counsel.

The Company 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 and expenses) 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 Company or any of the Guarantors (including this Section 7.07) or defending itself against any claim whether asserted by any Holder, the

Company 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 Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company and the Guarantors need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or gross negligence.

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

Notwithstanding anything contrary in Section 4.06 hereto, to secure the payment obligations of the Company 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)(8) or (9) 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 Code.

The Trustee shall comply with the provisions of Trust Indenture Act Section 313(b)(2) to the extent applicable. As used in this Section 7.07, the term “Trustee” shall also include each of the Paying Agent, Registrar, Collateral Agent and Transfer Agent, as applicable.

Section 7.08 Replacement of Trustee.

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 the Registrar, Paying Agent and Transfer Agent may resign with 60 days’ prior written notice and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing and may remove the Registrar, Paying Agent or Transfer Agent by so notifying such Registrar, Paying Agent or Transfer Agent, as applicable, with 90 days’ prior written notice.

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

(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 Code;

Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company’s expense), the Company or the Holders of at least 10% in aggregate 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, 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 Company. Thereupon, and upon payment of the retiring Trustee’s fees and expenses (including the fees and expenses of its agents and counsel), 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. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

As used in this Section 7.08, the term “Trustee” shall also include each of the Paying Agent, Registrar and Transfer Agent, as applicable.

Section 7.09 Successor Trustee by Merger, Etc.

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.

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).

Section 7.11 Preferential Collection of Claims Against Company.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

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

Section 8.02 Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.02, the Company and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04, be deemed to have been discharged from their obligations with respect to all outstanding Notes and Note Guarantees on the date the conditions set forth below are satisfied (“Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes and Note Guarantees, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all their other obligations under such Notes, Note Guarantees and this Indenture including that of the Guarantors (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments

acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on such Notes when such payments are due from the trust referred to in Section 8.04;

(b) the Company’s obligations with respect to the Notes concerning issuing temporary Notes, registration of 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, indemnities and immunities of the Trustee and the Company’s and the Guarantors’ obligations in connection therewith; and

(d) this Article 8.

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

Section 8.03 Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Company and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04, be released from their obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, clauses (1), (3), (4), (5), (6), (7) and (8) of Section 5.01(a), and Section 5.01(b) with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (“Covenant Defeasance”), the Note Guarantees will be released pursuant to Section 13.06 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 default 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 and Note Guarantees, the Company and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, Section 6.01(a)(3), 6.01(a)(4), 6.01(a)(5), 6.01(a)(6), 6.01(a)(7), 6.01(a)(8) (solely with respect to Restricted Subsidiaries that are Significant Subsidiaries), 6.01(a)(9) (solely with respect to Restricted Subsidiaries) and Section 6.01(a)(10) shall not constitute Events of Default.

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

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, and interest and premium, if any, on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date;

(3) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel stating that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default shall have occurred and be continuing either (a) on the date of such deposit; or (b) insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(6) the Company must have delivered to the Trustee an Opinion of Counsel to the effect that, assuming no intervening bankruptcy of the Company or any Guarantor between the date of deposit and the 91st day following the deposit and assuming that no Holder is an “insider” of the Company under applicable bankruptcy law, after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally, including Xxxxxxx 000 xx xxx Xxxxxx Xxxxxx Bankruptcy Code and Section 15 of the New York Debtor and Creditor Law;

to Section 8.04 in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or a Guarantor acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government Securities deposited pursuant to Section 8.04 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, the Trustee shall deliver or pay to the Company from time to time upon the written request of the Company any money or Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(2)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Company.

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

Section 8.07 Reinstatement.

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

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Notwithstanding Section 9.02, the Company, any Guarantor, the Trustee and the Collateral Agent, as applicable, may amend or supplement this Indenture, any Note Guarantee, any Security Document, any Intercreditor Agreement or Notes without the consent of any Holder:

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

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

(7) to conform this Indenture, the Notes, the Intercreditor Agreement or any Security Document to any provision of the “Description of Notes” in the Offering Memorandum to the extent such provision is intended to be a verbatim recitation thereof as certified in an Officer’s Certificate to the Trustee;

(8) to amend the Intercreditor Agreement to add additional holders of Additional Obligations permitted under this Indenture, the Intercreditor Agreement and any Additional Agreements then in effect;

(9) to amend the Security Documents to add any holders of Additional Pari Passu Obligations to the extent permitted under this Indenture, the Intercreditor Agreement and any Additional Pari Passu Agreement then in effect;

(10) to add to the Collateral securing the Notes; or

(11) provide for the issuance of Additional Notes under this Indenture in compliance with the terms hereof.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Company, each Guarantor party thereto, if any, the Trustee and the Collateral Agent, as applicable, may amend or supplement this Indenture, the Notes, the Note Guarantees, any Intercreditor Agreement and any Security Document with the consent of the Holders of at least a majority in aggregate principal amount of the Notes (including Additional Notes, if any) then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and, subject to Sections 6.04 and 6.07, any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes, the Note Guarantees, the Security Documents or any Intercreditor Agreement may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes, other than the Notes beneficially owned by the Company or its Affiliates (including Additional Notes, if any) (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes). Section 2.08 and Section 2.09 shall determine which Notes are considered to be “outstanding” for the purposes of this Section 9.02.

Without the consent of each Holder of outstanding Notes affected (including Notes beneficially owned by the Company or its Affiliates), 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 percentage or amount of the aggregate principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

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

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

(4) change the optional redemption dates or optional redemption prices of the Notes from those stated under Section 3.07;

(5) waive a Default or Event of Default in the payment of principal of, or interest, or premium on the Notes (except, upon a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes, a waiver of the payment default that resulted from such acceleration) or in respect of any other covenant or provision that cannot be amended or modified without the consent of all Holders;

(6) make any Note payable in money other than U.S. dollars;

(7) make any change in the amendment and waiver provisions of this Indenture that requires each Holder’s consent;

(8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture;

(9) impair the right to institute suit for the enforcement of any payment on or with respect to the Notes or the Note Guarantees; and

(10) amend, change or modify the obligation of the Company to make and consummate an Offer to Purchase with respect to any Asset Sale in accordance with the covenant described above under Section 4.07 after the obligation to make such Offer to Purchase has arisen, or the obligation of the Company to make and consummate an Offer to Purchase in the event of a Change of Control in accordance with the covenant described above under Section 4.09 after such Change of Control has occurred, including, in each case, amending, changing or modifying any definition relating thereto.

In addition, any amendment to, or waiver of, any provision of this Indenture or any Security Document that has the effect of releasing all or substantially all of the Collateral from the Liens of the Notes will require consent of the Holders of at least 67% in aggregate principal amount of the Notes then outstanding.

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

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

Section 9.03 Compliance with Trust Indenture Act.

Every amendment or supplement of 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.

Section 9.04 Effect of Consents.

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 amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds

every Holder; provided that any amendment or waiver that requires the consent of each affected Holder shall not become effective with respect to any non-consenting Holder.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement, or waiver. If a record date is fixed, then, notwithstanding the 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, whether or not such Persons continue to be Holders after such record date.

Section 9.05 Notation on or Exchange of Notes.

The Trustee at the request of the Issuer may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of 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.

Section 9.06 Trustee to Sign Amendments, Etc.

The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment, supplement or waiver until the Board of Directors approves it. In executing any amendment, supplement or waiver, the Trustee shall receive and (subject to Section 7.01) shall be fully protected in conclusively relying upon, in addition to the documents required by Section 15.03, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amendment, supplement or waiver is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Company and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof. 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.

ARTICLE 13

GUARANTEES

Section 13.01 Guarantee.

Subject to this Article 13, each of the Guarantors hereby, jointly and severally, 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 Company hereunder or thereunder, that: (a) the principal of, interest and premium, 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 Company 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 Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 13.01.

If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid either to the Trustee or such Holder, this Note 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 for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note 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 Note Guarantees.

Each Note Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company becomes 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 Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Note 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 Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

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

As used in this Section 13.01, the term “Trustee” shall also include each of the Paying Agent, Registrar and Transfer Agent, as applicable.

Section 13.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect 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 13, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Guarantor that makes a payment under its Note 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.

Section 13.03 Execution and Delivery.

To evidence its Note Guarantee set forth in Section 13.01, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by the Chief Executive Officer, the President, the Chief Financial Officer, the Treasurer, the Controller, any Executive Vice President, any Senior Vice President, any Vice President, the Secretary or any Assistant Secretary of the Guarantor or the sole member of the Guarantor, as the case may be, or any other officers of such Guarantor or such sole member, as the case may be, acting at the direction of any such foregoing officer. Each Guarantor hereby agrees to execute a Notation of Guarantee substantially in the form included in Exhibit A hereto on each Note authenticated and delivered by the Trustee.

Each Guarantor hereby agrees that its Guarantee set forth in Section 13.01 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 or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee shall be valid nevertheless.

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

Section 13.04 Subrogation.

Each Guarantor shall be subrogated to all rights of Holders of Notes against the Company in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 13.01; 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 Company under this Indenture or the Notes shall have been paid in full.

Section 13.05 Benefits Acknowledged.

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 Note Guarantee are knowingly made in contemplation of such benefits.

Section 13.06 Release of Guarantees.

A Note Guarantee of a Guarantor will be automatically and unconditionally released (and thereupon shall terminate and be discharged and be of no further force and effect):

(1) in connection with any sale or other disposition (including by merger or otherwise) of Capital Stock of the Guarantor after which such Guarantor is no longer a Subsidiary of the Company, if the sale of all such Capital Stock of that Guarantor complies with the applicable provisions of this Indenture;

(2) if the Company properly designates the Guarantor as an Unrestricted Subsidiary under this Indenture;

(3) upon a Legal Defeasance, Covenant Defeasance or satisfaction and discharge of this Indenture that complies with the provisions under Section 8.02, Section 8.03 or Section 14.01, respectively; or

(4) upon payment in full of the aggregate principal amount of all Notes then outstanding and all other obligations under this Indenture and the Notes then due and owing.

Upon any occurrence giving rise to a release of a Note Guarantee as specified above, the Trustee will, at the sole cost of the Company, execute any documents reasonably required in order to evidence or effect such release, termination and discharge in respect of such Note Guarantee. Neither the Company nor any Guarantor will be required to make a notation on the Notes to reflect any Note Guarantee or any such release, termination or discharge. Upon any release of a Guarantor from its Note Guarantee, such Guarantor shall also be released from its obligations under the Security Documents.

ARTICLE 14

SATISFACTION AND DISCHARGE

Section 14.01 Satisfaction and Discharge.

This Indenture shall be discharged and shall cease to be of further effect as to all Notes issued hereunder, when:

(b) all of the Notes (i) have become due and payable, (ii) will become due and payable at their Stated Maturity within one year or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the

Trustee in the name, and at the expense, of the Company, and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of deposit together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 14.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 14.01; provided that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of their obligations, the Company 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.

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

2. Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the February 15 or August 15 (whether or not a Business Day), as the case may be, immediately preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. If a Holder has given wire transfer instructions to the Company at least ten Business Days prior to the applicable payment date, the Company will pay through the Paying Agent all principal, interest and premium on that Holder’s Notes in accordance with those instructions. All other payments on Notes will be made at the office or agency of the Paying Agent and Registrar unless the Company elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders; provided that all payments of principal, premium, if any, and interest, with respect to the Global Notes registered in the name of or held by DTC or its nominee will be made by wire transfer of immediately available funds to the account specified by DTC.

Notes redeemed in part must be redeemed only in integral multiples of $1,000 and no Note with a principal amount of less than $2,000 will be redeemed in part, except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not $2,000 or a multiple of $1,000 in excess thereof, shall be redeemed.

In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed. Subject to Section 3.05 of the Indenture, on and after the Redemption Date, interest ceases to accrue on Notes or portions thereof called for redemption.

8. Offers to Repurchase.

A-6

any Notes being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes during a period beginning at the opening of business 15 days before the day of mailing of notice of redemption of Notes for redemption and ending at the close of business on the day of such mailing, (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.

10. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

11. Amendment, Supplement and Waiver. The Indenture, the Note Guarantees, the Security Documents, any Intercreditor Agreement or the Notes may be amended or supplemented as provided in the Indenture.

12. Defaults and Remedies. The Events of Default relating to the Notes are defined in Section 6.01 of the Indenture. If any Event of Default (other than as specified in Section 6.01(a)(8) or 6.01(a)(9) of the Indenture with respect to the Company) shall occur and be continuing with respect to the Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all unpaid principal of, premium, if any, and accrued interest on all Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the holders of the Notes) and upon any such declaration, such principal, premium, if any, and interest shall become due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default as specified in Section 6.01(a)(8) or 6.01(a)(9), with respect to the Company occurs and is continuing, then all the Notes shall become due and payable immediately in an amount equal to the principal amount of the Notes, together with accrued and unpaid interest, if any, to the date the Notes become due and payable, without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture, the Notes or the Note Guarantees except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if and so long as a committee of its Responsible Officers in good faith determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes waive, rescind or cancel any existing Default or Event of Default and its consequences under the Indenture if such waiver, rescission or cancellation would not conflict with any judgment or decree, except a continuing Default or Event of Default in the payment of the principal of, premium on, if any, or interest, if any on the Notes (including in connection with an offer to purchase); provided, however, 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. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required within ten (10) Business Days after becoming aware of any Default, to deliver to the Trustee a statement specifying such Default and any actions being taken by the Company and the Guarantors with respect thereto.

13. Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

14. No Recourse Against Others. No director, officer, employee, incorporator, stockholder, member, manager or partner of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture, the Note Guarantees, the Security Documents or any Intercreditor Agreement or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

15. Authentication. This Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of the Trustee or an authenticating agent.

16. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

17. GOVERNING LAW. THE INDENTURE, THE NOTES AND ANY NOTE GUARANTEE WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
