Section 2.07 Replacement Notes.

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

Every replacement Note is an additional obligation of the Issuers and will 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 Issuers or an Affiliate of either Issuer holds the Note; provided , however that Notes held by either of the Issuers or a Subsidiary of either Issuer shall be deemed to be not outstanding for purposes of Section 3.07(a).

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 protected 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 an Issuer, 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 will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by any Issuer or Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with any Issuer or Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

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

48

Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation.

The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirements of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Issuers upon written request. The Issuers may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Issuers default in a payment of interest on the Notes, they will 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 and in Section 4.01. The Issuers will 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. The Issuers will fix or cause to be fixed each such special record date and payment date, provided that no such special record date may 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 Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

(1) the clause of this Indenture pursuant to which the redemption shall occur;

(2) the redemption date;

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

(4) the redemption price.

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 will select Notes for redemption or purchase on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2, based on the method of the Depositary that most nearly approximates a pro rata selection), unless otherwise required by law or applicable stock exchange or depository requirements.

49

In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee will promptly notify the Issuers 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 and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Section 3.03 Notice of Redemption.

Subject to the provisions of Section 4.10 and Section 4.14, at least 30 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail (or, in the case of Notes in global form, pursuant to the Applicable Procedures of the Depositary), a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or Article 11.

The notice will identify the Notes to be redeemed and will state:

(1) the redemption date;

(2) the redemption price;

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note;

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

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

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

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

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

(9) if such redemption or notice is subject to satisfaction of one or more conditions precedent, that, in the Issuers’ discretion, the redemption date may be delayed until such time as

50

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.

At the Issuers’ request, the Trustee will give the notice of redemption in the Issuers’ names and at their expense; provided , however , that the Issuers have delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter time is acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Notwithstanding any provision hereof to the contrary, the notice of redemption with respect to a redemption pursuant to Section 3.07(b) need not set forth the Make-Whole Price but only the manner of calculation thereof. The Company will notify the Trustee in writing of the Make-Whole Price with respect to any redemption promptly after the calculation (in the case of Definitive Notes, at least two days prior to the redemption date), and the Trustee shall not be responsible for such calculation.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is sent in accordance with Section 3.03, Notes called for redemption become due on the date fixed for redemption, unless the redemption is subject to a condition precedent that is not satisfied or waived. Any redemption or notice of redemption may, at the Issuers’ discretion, be subject to one or more conditions precedent and, in the case of a redemption pursuant to Section 3.07(a), be given prior to and conditioned on the completion of the related Equity Offering.

Section 3.05 Deposit of Redemption or Purchase Price.

At least one Business Day prior to the redemption or purchase date, the Issuers will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, accrued interest and Liquidated Damages, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of, accrued interest and Liquidated Damages, if any, on all Notes to be redeemed or purchased.

If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will 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 an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuers 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 not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01.

Section 3.06 Notes Redeemed or Purchased in Part.

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

60

of the Chief Financial Officer of the General Partner, not materially more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided, further, that, in the case of Indebtedness, the incurrence of such Indebtedness was permitted by the terms of this Indenture;

(5) customary non-assignment provisions in contracts or licenses, easements or leases, in each case, entered into in the ordinary course of business;

(10) provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including, but not limited to, agreements entered into in connection with a Restricted Investment) entered into in the ordinary course of business or entered into with the approval of the Company’s Board of Directors;

(12) encumbrances or restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(13) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred stock is permitted pursuant to Section 4.09 and the terms of such preferred stock do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital Stock);

(14) obligations under Hedging Contracts permitted from time to time under this Indenture;

Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “ incur ”; with “ incurrence ” having a correlative meaning) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock, and will not permit any of its Restricted Subsidiaries to issue any preferred stock; provided, however , that the Issuers may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and any of the Guarantors may incur Indebtedness (including Acquired Debt) or issue preferred stock, if, for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued, the Fixed Charge Coverage Ratio of the Company would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period.

(b) Notwithstanding the foregoing, the provisions of Section 4.09(a) will not prohibit the incurrence of any of the following items of Indebtedness or issuances of Disqualified Stock or preferred stock, as applicable (collectively, “ Permitted Debt ”):

(1) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness and letters of credit under one or more Credit Facilities, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) does not exceed the greater of (a) $400.0 million and (b) $250.0 million plus 25% of the Company’s Consolidated Net Tangible Assets;

(2) the incurrence by the Company or its Restricted Subsidiaries of Existing Indebtedness;

62

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4) at any time; provided that, immediately after giving effect to any such incurrence, the principal amount of all Indebtedness incurred pursuant to this clause (4) and then outstanding does not exceed the greater of (a) $35.0 million and (b) 5% of the Company’s Consolidated Net Tangible Assets;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value, any Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the Company, or Indebtedness (other than intercompany Indebtedness) or preferred stock of any Restricted Subsidiary, in each case, that was permitted by this Indenture to be incurred under Section 4.09(a) or clause (2), (3), (4), (11), (12) or (15) of this Section 4.09(b) or this clause (5);

(6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided , however , that:

(A) if the Company or any Guarantor is the obligor on such Indebtedness and neither the Company nor a Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case where the Company is the obligor, or the Note Guarantee, in the case where a Guarantor is the obligor; and

(B)(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary 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) the incurrence by the Company or any of its Restricted Subsidiaries of obligations under Hedging Contracts in the ordinary course of business and not for speculative purposes;

(8) the Guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or any of its Restricted Subsidiaries that was permitted to be incurred by another provision of this Section 4.09;

(9) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of any preferred stock; provided, however , that:

(A) any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary; and

63

(B) any sale or other transfer of any such preferred stock to a Person that is neither the Company nor a Restricted Subsidiary,

will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (9);

(10) the incurrence by the Company or any of its Restricted Subsidiaries of liability in respect of the Indebtedness of any Unrestricted Subsidiary or any Joint Venture but only to the extent that such liability is the result of the Company’s or any such Restricted Subsidiary’s being a general partner or member of, or owner of an Equity Interest in, such Unrestricted Subsidiary or Joint Venture and not as a guarantor of such Indebtedness; provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (10) and then outstanding does not exceed $25.0 million;

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness;

(12) the incurrence by any Foreign Subsidiary of Indebtedness that, in the aggregate together with all other Indebtedness of all Foreign Subsidiaries (including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (12)), does not exceed the greater of (a) $75.0 million and (b) 25% of the Consolidated Net Tangible Assets of all Foreign Subsidiaries, considered as a single enterprise;

(13) the incurrence by the Company or any Restricted Subsidiary of Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and its Restricted Subsidiaries;

(14) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness constituting reimbursement obligations with respect to letters of credit; provided that, upon the drawing of such letters of credit, such obligations are reimbursed within 30 days following such drawing; and

(15) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness and the issuance by the Company of any Disqualified Stock, provided that, after giving effect to any such incurrence or issuance, the amount of all such Indebtedness and Disqualified Stock incurred or issued pursuant to this clause (15) and then outstanding (including all Permitted Refinancing Indebtedness and Disqualified Stock incurred to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value any Indebtedness or Disqualified Stock incurred or issued pursuant to this clause (15)) does not exceed the greater of (a) $35.0 million and (b) 5% of the Company’s Consolidated Net Tangible Assets.

(c) For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (15) of Section 4.09(b), or is entitled to be incurred pursuant to Section 4.09(a), the Company will be permitted in its sole discretion to divide, redivide, classify or reclassify such item of Indebtedness on the date of its incurrence, and later divide, redivide, classify or reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Any Indebtedness under the Credit Agreement outstanding on the Issue Date shall be deemed to have been incurred on such date pursuant to clause (1) of the definition of Permitted Debt. The accrual of interest or dividends with respect to preferred stock, the accretion

64

or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.09, provided that, in each such case, the amount thereof is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term. Further, the reclassification of any obligation of the Company or any of its Restricted Subsidiaries as Indebtedness due to a change in accounting principles will not be deemed an incurrence of Indebtedness for purposes of this Section 4.09.

(d) 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 utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; 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. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. The principal amount of any Permitted Refinancing Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

Section 4.10 Asset Sales.

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

(1) the Company or any of its Restricted Subsidiaries, as the case may be, receives consideration (including by way of relief from, or any Person assuming responsibilities for, any liabilities (other than any contingent liabilities)) at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received by the Company or its Restricted Subsidiaries in the Asset Sale (considered together on a cumulative basis, with all consideration received by the Company or any of its Restricted Subsidiaries in respect of other Asset Sales consummated since the Issue Date) is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(A) any liabilities, as shown on the Company’s or any of its Restricted Subsidiaries’ most recent balance sheet, of the Company or such Restricted Subsidiary (other than contingent liabilities and Subordinated Debt) that are assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement (or other legal documentation with the same effect) that releases the Company or such Restricted Subsidiary from or indemnifies the Company or such Restricted Subsidiary against further liability;

65

(B) any securities, notes or other obligations received by the Company or any of its Restricted Subsidiaries from such transferee that are, within 90 days after the Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;

(C) any Additional Assets of the kind referred to in clause (2) of Section 4.10(b); and

(D) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in respect of such Asset Sale.

(b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale or, if the Company or any of its Restricted Subsidiaries has entered into a binding commitment or commitments with respect to any of the actions described in clauses (2) or (3) below, within the later of (x) 365 days after the receipt of any Net Proceeds from an Asset Sale and (y) 180 days after the entering into of such commitment or commitments, the Company or any of its Restricted Subsidiaries may apply an amount equal to the amount of such Net Proceeds at its option to any combination of the following:

(1) to repay, redeem or repurchase any Senior Debt, provided that such repayment, redemption or repurchase may close up to 60 days after the end of such 365-day period;

(2) to invest in or acquire Additional Assets; or

(3) to make capital expenditures in respect of a Permitted Business.

Pending the final application of any Net Proceeds, the Company or any of its Restricted Subsidiaries may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(c) An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (1) through (3) of Section 4.10(b) will constitute “ Excess Proceeds .” Within ten Business Days after the aggregate amount of Excess Proceeds exceeds $30.0 million, the Company will make an offer (an “ Asset Sale Offer ”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets, to repurchase the maximum principal amount of Notes and to purchase, prepay or redeem such other pari passu Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest and Liquidated Damages, if any, to the date of repurchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest and Liquidated Damages, if any, due on an interest payment date that is on or prior to the date of repurchase, prepayment or redemption, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any of its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount

66

of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis (except that any Notes represented by a Note in global form will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law), based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000 or an integral multiple of $1,000 in excess of $2,000 will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(d) Notwithstanding the foregoing paragraphs of this Section 4.10, the sale, conveyance or other disposition of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by the provisions of Section 4.14 and/or Section 5.01 and not by this Section 4.10.

(e) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.10, or compliance with this Section 4.10 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

(f) In the event that, pursuant to the preceding provisions of this Section 4.10, the Issuers are required to commence an Asset Sale Offer, the Issuers will follow the procedures specified below.

(1) The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “ Offer Period ”). No later than three Business Days after the termination of the Offer Period (the “ Purchase Date ”), the Company will apply all Excess Proceeds (the “Offer Amount” ) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

(2) If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest and Liquidated Damages, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

(3) Upon the commencement of an Asset Sale Offer, the Company will send a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(A) that the Asset Sale Offer is being made pursuant to this Section 4.10 and the length of time the Asset Sale Offer will remain open;

67

(B) the Offer Amount, the purchase price and the Purchase Date;

(C) that any Note not tendered or accepted for payment will continue to accrue interest;

(D) that, unless the Issuers default in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;

(E) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 or integral multiples of $1,000 in excess thereof;

(F) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;

(G) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a letter or electronic transmission setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(H) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Company will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000 will be purchased); and

(I) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

(4) On or before the Purchase Date, the Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.10. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Issuers will promptly issue a new Note, and the Trustee, upon written request from the Issuers, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “ Affiliate Transaction ”), unless:

(1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors of the Company, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and

(10) transactions between the Company or any of its Restricted Subsidiaries and any other Person, a director of which is also on the Board of Directors of the Company or any direct or indirect parent company of the Company, and such common director is the sole cause for such other Person to be deemed an Affiliate of the Company or any of its Restricted Subsidiaries; provided, however , that such director abstains from voting as a member of the Board of Directors of the Company or any direct or indirect parent company of the Company, as the case may be, on any transaction with such other Person; and

Any Lien securing the Notes or Note Guarantees created pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the unconditional release and discharge of the initial Lien whose existence resulted in the creation of such Lien securing the Notes or Note Guarantees.

Section 4.14 Offer to Repurchase Upon Change of Control.

(a) If a Change of Control occurs, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes as set forth in the Notes and in Section 3.07, each Holder of Notes will have the right, except as provided below, to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that Holder’s

71

Notes pursuant to an offer (a “ Change of Control Offer ”) on the terms set forth in this Indenture. In the Change of Control Offer, the Company will offer to make a cash payment (a “ Change of Control Payment ”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Liquidated Damages, if any, on the Notes repurchased to the date of repurchase (the “ Change of Control Settlement Date ”), subject to the rights of Holders on the relevant record date to receive interest and Liquidated Damages, if any, due on an interest payment date that is on or prior to the Change of Control Settlement Date. Within 30 days following any Change of Control, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes as set forth in the Notes and in Section 3.07, the Company will send a notice to each Holder of Notes describing the transaction or transactions that constitute the Change of Control and offering to repurchase properly tendered Notes on the Change of Control Settlement Date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent. Furthermore, such notice shall state:

(1) that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the Change of Control Settlement Date;

(3) that any Note not tendered will continue to accrue interest;

(4) that, unless the Issuers default in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Settlement Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Settlement Date;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Settlement Date, a letter or electronic transmission setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, or compliance with the provisions of this Section 4.14 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.14 by virtue of such compliance.

72

(b) Promptly following the expiration of the Change of Control Offer, the Company will, to the extent lawful, accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer. Promptly after such acceptance, the Company will, on the Change of Control Settlement Date:

(1) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(2) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

On the Change of Control Settlement Date, the Paying Agent will send to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depositary), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Settlement Date, unless the Company defaults in making the Change of Control Payment. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Settlement Date.

(c) Notwithstanding any provision to the contrary, the Company will not be required to make a Change of Control Offer upon a Change of Control, if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in Section 4.14(a) applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (2) notice of redemption of all outstanding Notes has been given pursuant to Section 3.07 unless and until there is a default in payment of the applicable redemption price or (3) in connection with or in contemplation of any Change of Control, the Company has made an offer to purchase (an “ Alternate Offer ”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer. Notwithstanding anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer or Alternate Offer is made.

(d) In the event that Holders of not less than 90% in aggregate principal amount of the outstanding Notes accept a Change of Control Offer or Alternate Offer and the Company (or any third party making such Change of Control Offer in lieu of the Company as set forth in Section 4.14(c)) purchases all of the Notes held by such Holders, the Company will have the right set forth in Section 3.07(c) to redeem all of the Notes that remain outstanding.

Section 4.15 Additional Note Guarantees.

If, after the Issue Date, any Domestic Subsidiary of the Company that is not already a Guarantor Guarantees or otherwise becomes obligated with respect to any Indebtedness of the Company or any Guarantor under any Credit Facility, then that Domestic Subsidiary will become a Guarantor by executing a supplemental indenture and delivering it to the Trustee within 20 Business Days of the date on which it Guaranteed such Indebtedness; provided , however , that the preceding shall not apply to Subsidiaries of

73

the Company that have properly been designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Note Guarantee of a Restricted Subsidiary that was incurred pursuant to this paragraph will be released as provided in Section 10.05.

Section 4.16 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.07 or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors of the Company giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by the under Section 4.07. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 the Company will be in default of such covenant.

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09 calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable four-quarter reference period and (2) no Default or Event of Default would be in existence following such designation.

Section 4.17 Termination of Covenants.

If at any time (a) the Notes have an Investment Grade Rating from at least two Rating Agencies, (b) no Default has occurred and is continuing under this Indenture and (c) the Company has delivered to the Trustee an Officers’ Certificate certifying as to the satisfaction of the conditions set forth in the foregoing clauses (a) and (b) of this sentence, the Company and its Restricted Subsidiaries will no longer be subject to the provisions of Section 4.07, Section 4.08, Section 4.09, Section 4.10, Section 4.11, Section 4.14 and clause (4) of Section 5.01(a).

(A) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “ Payment Default ”); or

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $25.0 million or more; provided, however, that if, prior to any acceleration of the Notes, (i) any such Payment Default is cured or waived, (ii) any such acceleration of such Indebtedness is rescinded, or (iii) such Indebtedness is repaid within a period of 10 Business Days from the continuation of such default beyond any applicable grace period for such Payment Default or the occurrence of such acceleration, as the case may be, then any Default or Event of Default (but not any acceleration of the Notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

77

(7) failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company), would constitute a Significant Subsidiary to pay final judgments (entered by a court or courts of competent jurisdiction) aggregating in excess of $25.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed for a period of 60 days;

78

Section 6.02 Acceleration.

In the case of an Event of Default specified in clause (9) or (10) of Section 6.01, with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all then outstanding Notes will become due and payable immediately without further action or notice (subject to applicable law). If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately by notice in writing to the Company and, in the case of a notice by such Holders, also to the Trustee specifying the respective Event of Default and that it is a notice of acceleration.

Upon any such declaration, the Notes shall become due and payable immediately.

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, rescind an acceleration and its consequences if the rescission would not violate any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Liquidated Damages, if any, that has become due solely because of the acceleration) have been cured or waived.

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 of, premium, if any, on, or interest and Liquidated Damages, if any, on, the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

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 any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, on, or interest and Liquidated Damages, if any, on, the Notes; 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 shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Holders of a majority in aggregate principal amount of the then outstanding Notes may 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. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

79

Section 6.06 Limitation on Suits.

Subject to the provisions of Section 7.01, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest and Liquidated Damages, if any, when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or any Affiliate of the Issuers with the same rights it would have if it were not Trustee.

Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.10 and Section 7.11.

Section 7.04 Trustee’s Disclaimer.

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will 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.

The Trustee will not be deemed to have notice of any Default or Event of Default, except Events of Default under clause (1) or (2) of Section 6.01, unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event that is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

83

Section 7.06 Reports by Trustee to Holders of Notes.

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

(b) A copy of each report at the time it is sent to the Holders of Notes will be mailed by the Trustee to the Issuers and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d).

Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

The Trustee will notify the Issuers and the Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers and the Guarantors will not relieve the Issuers or any of the Guarantors of their obligations hereunder unless the failure to notify the Issuers or the Guarantors impairs any Issuer’s or Guarantor’s respective ability to defend such claim. Such Issuer or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Issuers will pay the reasonable fees and expenses of such counsel. Neither Issuer nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c) The obligations of the Issuers and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture.

Such Lien will survive the satisfaction and discharge of this Indenture.

84

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in clause (9) or (10) of Section 6.01 occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

(f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuers, 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.

The retiring Trustee will 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 Issuers’ obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

85

Section 7.09 Successor Trustee by Merger, etc.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuers may at any time, at the option of their respective Boards of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or Section 8.03 be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

86

Section 8.02 Legal Defeasance and Discharge.

Upon the Issuers’ exercise under Section 8.01 of the option applicable to this Section 8.02, each Issuer and each of the Guarantors will, 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 (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “ Legal Defeasance ”). For this purpose, Legal Defeasance means that the Issuers and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

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

(2) the Issuers’ obligations with respect to the Notes under Section 2.04, Section 2.06, Section 2.07, Section 2.10 and Section 4.02;

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

(4) the Legal Defeasance provisions of 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 Issuers’ exercise under Section 8.01 of the option applicable to this Section 8.03, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04, be released from each of their obligations under Section 4.03, Section 4.07, Section 4.08, Section 4.09, Section 4.10, Section 4.11, Section 4.12, Section 4.13, Section 4.14, Section 4.15, Section 4.16, Section 4.17 and Section 5.01(a)(4) with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (such release and termination hereinafter referred to as “ Covenant Defeasance ”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply with and will 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 will 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 will be unaffected thereby. In addition, upon the Issuers’ 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, clauses (3) through (7) of Section 6.01 and, only with respect to Subsidiaries of the Company, clauses (9) and (10) of Section 6.01 will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance under Section 8.02 or Covenant Defeasance under Section 8.03:

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

(B) since the Issue Date, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred;

(3) in the case of an election under Section 8.03, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming 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 has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

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

(6) the Issuers must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders of Notes over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuers or others;

(7) the Company must deliver to the Trustee an Officers’ Certificate, stating that all conditions precedent set forth in clauses (1) through (6) of this Section 8.04 have been complied with; and

(8) the Company must deliver to the Trustee an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions, qualifications and exclusions), stating that all conditions precedent set forth in clauses (2), (3) and (5) of this Section 8.04 have been complied with; provided that the Opinion of Counsel with respect to clause (5) of this Section 8.04 may be to the knowledge of such counsel.

88

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 8.04 in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including an Issuer 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 and Liquidated Damages, if any, but such money need not be segregated from other funds except to the extent required by law.

The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable 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.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuers from time to time, upon the request of the Issuers any money or non-callable 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 clause (1) of Section 8.04), 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.

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

Notes and the Note Guarantees with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or Exchange Offer for, Notes), and, subject to Section 6.04 and Section 6.07, any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a purchase of, or tender offer or Exchange Offer for, Notes).

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

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 of the proposed amendment, supplement or waiver.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. Subject to Section 6.04 and Section 6.07, the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture, the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(2) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes; provided , however , that any purchase or repurchase of Notes, including pursuant to Section 4.10 and Section 4.14, shall not be deemed a redemption of the Notes;

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

(4) waive a Default or Event of Default in the payment of principal of, premium, if any, or interest and Liquidated Damages, if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders of a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

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

91

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

(7) waive a redemption payment with respect to any Note; provided, however, that any purchase or repurchase of Notes, including pursuant to Section 4.10 and Section 4.14, shall not be deemed a redemption of the Notes;

(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; or

(9) make any change in the preceding amendment, supplement and waiver provisions.

Section 9.03 Compliance with Trust Indenture Act.

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

Section 9.04 Revocation and 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.

The Issuers may fix a record date for determining which Holders must consent to such amendment, supplement or waiver. If the Issuers fix a record date, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation pursuant to Section 2.05, or (ii) such other date as the Issuers shall designate.

Section 9.05 Notation on or Exchange of Notes.

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

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

Section 9.06 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. No Issuer may sign an amended or supplemental indenture until its Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01) will be fully protected in relying upon, in addition to the documents required by Section 12.04, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE 10

NOTE GUARANTEES

Section 10.01 Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:

(1) the principal of, premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest on, the Notes, if lawful (subject in all cases to any applicable grace period provided herein), and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will 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.

(b) The Guarantors hereby agree that, to the maximum extent permitted under applicable law, their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against any Issuer, any action to enforce the same or any other circumstance that might otherwise constitute a legal or equitable discharge or defense of a Guarantor. To the extent permitted by applicable law, each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against an Issuer, protest, notice and all demands whatsoever and covenant that the Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

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

(d) Each Guarantor agrees that it will 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, to the extent permitted by applicable law, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the

93

maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of the Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6, such obligations (regardless of whether due and payable) will forthwith become due and payable by the Guarantors for the purpose of the Note Guarantee. The Guarantors will 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 Guarantee.

Section 10.02 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 Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that 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 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Note Guarantee Notation.

To evidence its Note Guarantee set forth in Section 10.01, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

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 will be valid nevertheless.

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

In the event that either Issuer or any of its Restricted Subsidiaries creates or acquires any Domestic Restricted Subsidiary after the Issue Date, if required by Section 4.15, the Company will cause such Domestic Restricted Subsidiary to comply with the provisions of Section 4.15 and this Article 10, to the extent applicable.

94

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.05, no Guarantor may sell or otherwise dispose of, in one or more related transactions, all or substantially all of its properties or assets to, or consolidate with or merge with or into (regardless of whether such Guarantor is the surviving Person), another Person, other than the Company or another Guarantor, unless:

(1) immediately after giving effect to such transaction or series of related transactions, no Default or Event of Default exists; and

(2) either:

(A)(i) such Guarantor is the surviving Person of such consolidation or merger or (ii) the Person acquiring the properties or assets in any such sale or other disposition or the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) unconditionally assumes all the obligations of such Guarantor under the Notes and this Indenture (including its Note Guarantee) pursuant to a supplemental indenture satisfactory to the Trustee; or

(B) such transaction or series of transactions does not violate the provisions of Section 4.10.

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.

Except as set forth in Article 4 and Article 5, and notwithstanding clauses (A) and (B) immediately above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 10.05 Releases.

The Note Guarantee of a Guarantor will be released automatically:

(1) in connection with any sale or other disposition of all or substantially all of the properties or assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate the provisions of Section 4.10;

(2) in connection with any sale or other disposition of the Capital Stock of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate the provisions Section 4.10 and the Guarantor ceases to be a Restricted Subsidiary as a result of such sale or other disposition;

(3) if the Company designates such Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture;

(4) upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 or satisfaction and discharge of this Indenture in accordance with Article 11;

95

(5) upon the liquidation or dissolution of such Guarantor, provided that no Default or Event of Default occurs as a result thereof or has occurred or is continuing;

(6) upon such Guarantor consolidating with, merging into or transferring all of its properties or assets to the Company or another Guarantor and, as a result of or in connection with such transaction, such Guarantor dissolves or otherwise ceases to exist; or

(7) at such time as such Guarantor is no longer required to Guarantee any Indebtedness of the Company, Finance Corp. or any other Guarantor under any Credit Facility.

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of, premium, if any, and interest on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

ARTICLE 11

SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

This Indenture will be satisfied and discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration of transfer or exchange of the Notes and as otherwise specified in this Indenture), when:

(1) either:

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

(B) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the sending of a notice of redemption or otherwise or will become due and payable within one year and either an Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal of, premium, if any, and interest and Liquidated Damages, if any, on, the Notes to the date of maturity or redemption;

(2) in respect of clause (B) of Section 11.01(1), no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which either Issuer or any Guarantor is a party or by which either Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and, in each case, the granting of Liens to secure such borrowings);

96

(3) the Issuers have, or any Guarantor has, paid or caused to be paid all sums payable by them under this Indenture; and

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

In addition, the Issuers must deliver to the Trustee (a) an Officers’ Certificate, stating that all conditions precedent set forth in clauses (1) through (4) of this Section 11.01 have been satisfied and (b) an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and qualifications), stating that the condition precedent set forth in clause (4) of this Section 11.01 has been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to clause (B) of Section 11.01(1), the provisions of Section 11.02 and Section 8.06 will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02 Application of Trust Money.

Subject to the provisions of Section 8.06, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by the Trustee, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including an Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest and Liquidated Damages, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided that if the Issuers have made any payment of principal of, premium, if any, or interest and Liquidated Damages, if any, on, any Notes because of the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

(b) Holders of Transfer Restricted Securities . A Person is deemed to be a holder of Transfer Restricted Securities (each, a “ Holder ”) whenever such Person owns Transfer Restricted Securities.

SECTION 3. Registered Exchange Offer .

(a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy, the Obligors shall (i) use their commercially reasonable efforts to cause to be filed with the Commission after the Issue Date, a Registration Statement under the Securities Act relating to the Exchange Notes and the Exchange Offer, (ii) use their commercially reasonable efforts to cause such Registration Statement to become effective under the Securities Act not later than 365 days after the Issue Date, (iii) in connection with the foregoing, file (A) all pre-effective amendments to such Registration Statement as may be necessary in order to cause such Registration Statement to become effective, (B) if applicable, a post-effective amendment to such Registration Statement pursuant to Rule 430A under the Securities Act and (C) any necessary filings in connection with the registration and qualification of the Exchange Notes to be made under the state securities or blue sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, and (iv) promptly after such Registration Statement is declared effective by the Commission, commence the Exchange Offer. The Exchange Offer Registration Statement shall be on the appropriate form permitting (i) registration of the offer and issuance of the Exchange Notes to be offered in exchange for the Initial Notes that are Transfer Restricted Securities and (ii) resales of the Exchange Notes by Broker-Dealers who currently hold Transfer Restricted Securities that were acquired for their own account as a result of market-making activities or other trading activities (other than Initial Notes acquired directly from the Issuers or any of their Affiliates) as contemplated by Section 3(c) below.

(b) The Obligors shall use their commercially reasonable efforts to cause the Exchange Offer Registration Statement to be effective continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable United States federal and state securities laws to Consummate the Exchange Offer; provided , however , that in no event shall such period be less than 20 Business Days after the date on which notice of the Exchange Offer is mailed to the Holders. The Obligors shall cause the Exchange Offer to

comply with all applicable United States federal and state securities laws. No securities other than the Exchange Notes shall be included in the Exchange Offer Registration Statement. The Obligors shall use their commercially reasonable efforts to cause the Exchange Offer to be Consummated no later than 30 Business Days after the date on which the Exchange Offer Registration Statement has become effective, or such later date as may be required by United States federal securities laws.

(c) The Issuers shall indicate in a “Plan of Distribution” section contained in the Prospectus forming a part of the Exchange Offer Registration Statement that any Broker-Dealer who holds Initial Notes that are Transfer Restricted Securities that were acquired for its own account as a result of market-making activities or other trading activities (other than Transfer Restricted Securities acquired directly from the Issuers or any of their Affiliates), may exchange such Initial Notes pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Notes received by such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of Distribution” section shall also contain all other information with respect to such resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of Initial Notes held by any such Broker-Dealer except to the extent requested or required by the Commission as a result of a change in policy after the date of this Agreement.

The Obligors shall use their commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented and amended as required by the provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Initial Notes acquired by any Broker-Dealer for its own account as a result of market-making activities or other trading activities, and to ensure that the Exchange Offer Registration Statement conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 180 days from the date on which the Exchange Offer Registration Statement is declared effective by the Commission and (ii) the date on which Broker-Dealers are no longer required to deliver a prospectus in connection with market-making or other trading activities.

SECTION 4. Shelf Registration .

(a) Shelf Registration . If (i) the Obligors are not permitted to file an Exchange Offer Registration Statement or to consummate the Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy, (ii) for any reason the Exchange Offer is not Consummated within 30 Business Days after the Effectiveness Target Date with respect to the Exchange Offer Registration Statement, or (iii) with respect to any Holder of Transfer

5

Restricted Securities, such Holder notifies the Issuers prior to the 20th Business Day following the consummation of the Exchange Offer that (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer, (B) such Holder may not resell the Exchange Notes acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial Notes acquired directly from the Issuers or one of their Affiliates, then, upon such Holder’s request, the Obligors shall

(x) use their commercially reasonable efforts to cause to be filed a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “ Shelf Registration Statement ”), on or prior to 30 days after the occurrence (a “ Shelf Registration Event ”) of (i), (ii) or (iii) of the first sentence of Section 4(a) (such date being the “ Shelf Filing Date ”), which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and

(y) use their commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission as promptly as practicable following the filing of such Shelf Registration Statement, and in any event, on or prior to 90 days after the occurrence of a Shelf Registration Event.

The Obligors shall use their commercially reasonable efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Notes by the Holders of Transfer Restricted Securities entitled to the benefit of this Section 4(a), and to ensure that the Shelf Registration Statement conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, until the earlier of (i) one year following the effective date of such Shelf Registration Statement and (ii) the date on which all the Initial Notes covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement.

(b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement . No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Issuers in writing, within 20 days after receipt of a request therefor, such information as the Issuers may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. No Holder of Transfer Restricted Securities shall be entitled to Liquidated Damages pursuant to Section 5 hereof unless such Holder shall have timely provided all such information. Each Holder as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Issuers all information required to be disclosed in order to make the information previously furnished to the Issuers by such Holder not misleading.

SECTION 5. Liquidated Damages . (a) If (i) a Shelf Registration Statement is required to be filed by this Agreement and is not filed with the Commission on or prior to the Shelf Filing Date, (ii) any of the Registration Statements required by this Agreement has not been declared effective by the Commission on or prior to the date specified for such effectiveness in this Agreement (the “ Effectiveness Target Date ”), (iii) the Exchange Offer has not been Consummated within 30 Business Days after the Effectiveness Target Date with respect to the Exchange Offer Registration Statement or (iv) any Registration Statement required by this Agreement is filed and declared effective by the Commission but shall thereafter cease to be effective or usable for its intended purpose without being succeeded within three days by a post-effective amendment to such Registration Statement that cures such failure and that is itself declared effective within five days of filing such post-effective amendment to such Registration Statement (each such event referred to in clauses (i) through (iv), a “ Registration Default ”), the Obligors hereby agree to pay damages (“ Liquidated Damages ”) to each Holder of the Transfer Restricted Securities in an amount equal to 0.25% per annum on the principal amount of Transfer Restricted Securities held by such Holder during the 90-day period immediately following the occurrence of the first Registration Default and such amount shall increase by 0.25% per annum at the end of such 90-day period; provided that in no event shall the Liquidated Damages under this Agreement exceed 0.50% per annum. Notwithstanding anything to the contrary set forth herein, (1) upon filing of the Shelf Registration Statement in the case of clause (i) above, (2) upon the effectiveness of the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement), in the case of (ii) above, (3) upon Consummation of the Exchange Offer, in the case of (iii) above, or (4) upon the filing of a post-effective amendment to the Registration Statement or an additional Registration Statement that causes the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement) to again be declared effective or made usable in the case of (iv) above, in each of clauses (1) through (4) above, in accordance with the requirements set forth herein the Registration Default specified in such clause shall be deemed to have been cured. Following the cure of all Registration Defaults relating to any particular Transfer Restricted Securities, Liquidated Damages relating to such Transfer Restricted Securities shall cease to accrue; provided , however , that, if after Liquidated Damages have ceased to accrue, a different Registration Default occurs, Liquidated Damages shall again accrue pursuant to the foregoing provisions. All accrued Liquidated Damages shall be paid in the manner provided for the payment of interest on the Initial Notes as set forth in the Indenture. Notwithstanding the foregoing, the amount of Liquidated Damages shall not increase as a result of more than one Registration Default having occurred (and being pending at the same time). A Registration Default referred to in clause (iv) of this Section 5(a) shall be deemed not to have occurred and be continuing in relation to a Shelf Registration Statement required by this Agreement or the related Prospectus if (i) such Registration Default has occurred solely as a result of material events with respect to the Obligors that would need to be described in such Shelf Registration Statement or the related Prospectus and such event is not so described therein and (ii) the Obligors are proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related Prospectus to describe such events; provided, however , that in any case if such Registration Default occurs for a continuous period in excess of 30 days in any 12-month period, Liquidated Damages shall be payable in accordance with this Section 5(a) from the 31st day after such Registration Default occurs until such Registration Default is cured.

7

(b) All obligations of the Obligors to pay Liquidated Damages set forth in the preceding paragraph that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive (subject to the proviso of the immediately preceding sentence) until such time as all such obligations with respect to such security shall have been satisfied in full.

Each Holder, including any Holder that is a Broker-Dealer, shall acknowledge and agree that any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission enunciated in Morgan Stanley & Co., Inc . (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters (which may include any no-action letter obtained pursuant to clause (i) above), and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by an effective registration

(i) use their commercially reasonable efforts to keep such Registration Statement continuously effective and provide all requisite financial statements, including, if required by the Securities Act or any regulation thereunder, financial statements of the Guarantors, for the period specified in Section 3 or 4 hereof, as applicable; upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Obligors shall file promptly an appropriate amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use their commercially reasonable efforts to cause such amendment to be declared effective by the Commission and such Registration Statement and the related Prospectus to become usable for their intended purpose(s) as soon as practicable thereafter;

If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or blue sky laws, the Obligors shall use their commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time;
