Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto).

Section 2.02. Execution and Authentication .

At least one Officer must sign the Notes for the Company by manual or facsimile signature.

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

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

The Trustee will, upon receipt of a written order of the Company signed by two Officers (an “ Authentication Order ”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 (“Replacement Notes”) hereof.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so.

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

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

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held

31

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

Section 2.05. Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA § 312(a).

At any time prior to such cancellation, if any beneficial

46

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

(i) General Provisions Relating to Transfers and Exchanges.

(1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and Certificated Notes upon receipt of an Authentication Order in accordance with Section 2.02 (“Execution and Authentication”) hereof or at the Registrar’s request.

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Certificated Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10 (“Temporary Notes”), 3.06 (“Notes Redeemed or Purchased in Part”), 3.09 (“Offer to Purchase by Application of Excess Proceeds”), 4.18 (“Offer to Repurchase Upon Change of Control”), 4.19 (“Asset Sales”) and 9.05 (“Notation on or Exchange of Notes”) hereof).

(3) The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

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

(5) Neither the Registrar nor the Company will be required:

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

Section 2.07. Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company 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 Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. If, after the delivery of such replacement Note, a bona fide purchaser of the original Note in lieu of which such replacement Note was issued presents for payment or registration such original Note, the Trustee shall be entitled to recover such replacement Note from the Person to whom it was delivered or any Person taking therefrom, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Company, the Trustee and any Agent in connection therewith.

Except as set forth in Section 2.09 (“Treasury Notes”) hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07(a) (“Optional Redemption”) hereof.

48

If a Note is replaced pursuant to Section 2.07 (“Replacement Notes”) hereof, 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 (“Payment of Notes”) hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any of the foregoing) 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 the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any 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 knows are so owned will be so disregarded.

Section 2.10. Temporary Notes.

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

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

Section 2.11. Cancellation.

The Company 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 and the Trustee). Certification of the destruction or cancellation of all canceled Notes will be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12. Overdue Interest; Default Interest; Additional Interest.

The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, and interest (without regard to

49

any applicable grace period) from time to time at the rate then in effect on the Notes to the extent lawful to the Persons who are Holders on a subsequent Record Date, in each case at the rate provided as set forth in the Notes and consistent with Section 4.01 (“Payment of Notes”) hereof (such interest, “ Overdue Interest ”). The Company will notify the Trustee in writing of the amount of Overdue Interest proposed to be paid on each Note and the date of the proposed payment. The Company 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 Overdue Interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail 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.

In addition, the Company will pay Default Interest, if any, that accrues as described under Section 6.01 (“Events of Default”) to the extent that the Company elects to pay such Default Interest pursuant to Section 6.01 and will pay Additional Interest, if any, to Holders of Notes pursuant to the Registration Rights Agreement.

Section 2.13. Persons Deemed Owners.

The Holder of a Note may be treated as its owner for all purposes. Only Holders have rights under this Indenture and the Notes.

Section 2.14. Interest Payment Date; Record Date.

Interest on outstanding Notes will accrue from March 18, 2014 at the rate of 6.125% per annum and will be payable semi-annually in arrears on March 15 and September 15 of each year, commencing on September 15, 2014 (each, an “ Interest Payment Date ”). The Company will make each interest payment to the Holders of record on the immediately preceding March 1 and September 1 (each, a “ Record Date ”). Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in minimum amounts of $2,000 and integral multiples of $1,000; 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 3.09 (“Offer to Purchase by Application of Excess Proceeds”) hereof, 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, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles VIII or X hereof.

51

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

If the Company complies 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 a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption or purchase is not so paid upon surrender for

52

redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 (“Payment of Notes”) hereof.

(6) 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;

(7) 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 telegram, telex, facsimile transmission or letter 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;

(8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Trustee 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 no Note of $2,000 or less can be redeemed in part and that minimum denominations of $1,000 in excess thereof are maintained); and

55

and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note in a principal amount equal to any unpurchased portion of the Notes surrendered, if any. 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.

(5) so long as no Default has occurred and is continuing or, immediately after giving effect thereto, would be caused thereby, the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any existing or former employee or

60

director of the Company (or any of its Restricted Subsidiaries) pursuant to any employment agreements, equity subscription agreement, stock option agreement, management equity plan or stock option plan or other management or employee benefit plan, agreement or trust or similar agreements and plans; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests pursuant to this clause (5) may not exceed the sum of (i) $5.0 million in any twelve-month period, (ii) the aggregate net proceeds received by the Company during such twelve-month period from the issuance of such Equity Interests (other than Disqualified Stock) pursuant to such agreements or plans and (iii) the net cash proceeds of key man life insurance received by the Company or its Restricted Subsidiaries after the Issue Date;

portion of such Restricted Payment among all clauses of the preceding paragraph (as of the Issue Date, such clauses being clauses (b)(1) through (b)(10)) or among such clauses and the preceding paragraph (a) including clauses (A), (B) and (C), provided that at the time of such allocation or reallocation, all such Restricted Payments, or allocated portions thereof, would be permitted under the various provisions of the foregoing covenant.

Section 4.08. 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 ”) 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 shares of preferred stock; provided, however , that the Company and any Guarantor may incur Indebtedness (including Acquired Debt) and the Company may issue Disqualified Stock if the Fixed Charge Coverage Ratio 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 is issued would have been at least 2.0 to 1, 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 had been issued, as the case may be, at the beginning of such four-quarter period.

(b) The provisions of Section 4.08(a) hereof will not apply to or prohibit the incurrence of any of the following items of Indebtedness (collectively, “ Permitted Debt ”):

(1) Indebtedness of the Company or any Guarantors of Indebtedness under one or more Credit Facilities in an aggregate principal amount at any one time outstanding (with outstanding letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Subsidiaries thereunder at each relevant time of determination) not to exceed the greater of (a) $400.0 million and (b) $100.0 million plus 30% of the Company’s Consolidated Net Tangible Assets;

62

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

(A) if the Company or any Guarantor is the obligor on such Indebtedness and a Restricted Subsidiary of the Company which is not a Guarantor is the obligee thereon, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, in the case of the Company, or the Subsidiary Guarantee, in the case of a Guarantor; 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 not either the Company or a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or a Restricted Subsidiary, as the case may be, on the date of such issuance, sale or transfer that is not then permitted by this clause (6);

(7) Hedging Obligations of the Company or any of its Restricted Subsidiaries incurred in the normal course of business and not for speculative purposes, designed to protect the Company or such Restricted Subsidiary against fluctuations in interest rates or currency exchange rates with respect to Indebtedness incurred or against fluctuations in the price of commodities used by that entity at the time;

(8) Guarantees by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or any Restricted Subsidiary that was permitted to be incurred by another provision of this Section 4.08; provided that if such Indebtedness being guaranteed is subordinated in right of payment to the Notes or a Subsidiary Guarantee, then the Guarantee of that Indebtedness by the Company or the Guarantor shall be subordinated in right of payment to the Notes or the Guarantor’s Subsidiary Guarantee, as the case may be;

(9) Indebtedness of the Company or any of its Restricted Subsidiaries in respect of workers’ compensation claims, self-insurance obligations, bid, performance, surety, appeal and similar bonds and obligations and completion guarantees provided by the Company or a Restricted Subsidiary in the ordinary course of business;

(10) Indebtedness of the Company or any of its the Restricted Subsidiaries arising from the honoring by a bank or other financial institution of a check, draft or similar instrument (except in the case of daylight overdrafts) drawn against insufficient

funds in the ordinary course of business; provided that such Indebtedness is extinguished within five Business Days following the Company’s receipt of notice of the incurrence thereof;

(11) Indebtedness of the Company or any of its the Restricted Subsidiaries represented by agreements of the Company or a Restricted Subsidiary of the Company providing for indemnification, adjustment of purchase price or similar obligations, earn-outs or other similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business, assets or Capital Stock of the Company or any such Restricted Subsidiary; provided that the maximum aggregate liability in respect of all such Indebtedness incurred in connection with a disposition shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in connection with such disposition;

(12) Acquired Debt of the Company or any of its Restricted Subsidiaries to the extent such Indebtedness was Indebtedness of (a) a Subsidiary prior to the date on which such Subsidiary became a Restricted Subsidiary of the Company or (b) a Person that was acquired (by acquisition of its Capital Stock, merger, consolidation or otherwise) by the Company or any of its Restricted Subsidiaries (other than Indebtedness incurred in connection with, or in contemplation of, such acquisition); provided that, at the time such Subsidiary becomes a Restricted Subsidiary or is acquired by the Company or any Restricted Subsidiary of the Company, the Company would have been able to incur $1.00 of additional Indebtedness pursuant to Section 4.08(a) immediately after giving effect to the incurrence of such Indebtedness pursuant to this clause (12); and

(13) to the extent not otherwise permitted by any other Permitted Debt clause, Indebtedness of the Company or any of its Restricted Subsidiaries in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (13), not to exceed the greater of (a) $50.0 million and (b) 5.0% of the Company’s Consolidated Net Tangible Assets.

For purposes of determining compliance with this Section 4.08, if an item of proposed Indebtedness (including Acquired Debt) at any time meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (13) of this Section 4.08(b), or is entitled to be incurred pursuant to Section 4.08(a), the Company will be permitted to classify (and later reclassify) in whole or in part in its sole discretion such item of Indebtedness in any manner that complies with this Section 4.08, and such item of Indebtedness or portion thereof may be classified (or later classified or reclassified) in whole or in part as having been incurred under more than one of the applicable clauses of Permitted Debt under this Section 4.08(b) or pursuant to Section 4.08(a). Indebtedness permitted by this Section 4.08 need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or none other provisions of this Section 4.08 permitting such Indebtedness.

The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same

64

terms, and the accretion or payment of dividends on any Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.08; provided , in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued.

If an Unrestricted Subsidiary incurs Non-Recourse Debt and any such Indebtedness ceases to be Non-Recourse Debt of such Unrestricted Subsidiary, then such event shall be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Company that is subject to this Section 4.08. In addition, if at any time an Unrestricted Subsidiary fails to meet the definitional requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture, and any then outstanding Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date, and such incurrence will be subject to this Section 4.08.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto will be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred; provided that, if such Indebtedness is incurred to refinance other Indebtedness denominated in the same 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, the U.S. dollar-denominated restriction will be deemed not to have been exceeded so long as the principal amount of the refinancing Indebtedness does not exceed the principal amount of the Indebtedness being refinanced. Notwithstanding any other provision of this Section 4.08, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.08 will not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies.

The amount of any Indebtedness outstanding as of any date will be:

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

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness;

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

(A) the Fair Market Value of such assets at the date of determination; and

(B) the amount of the Indebtedness of the other Person; and

(4) if Indebtedness is secured by a letter of credit that only secures such Indebtedness, then the aggregate amount deemed incurred by such Indebtedness and such letter of credit shall be equal to the greater of (a) the principal amount of such Indebtedness and (b) the amount that can be drawn under such letter of credit.

Section 4.09. Liens.

The Company will not, and will not permit any of the Restricted Subsidiaries to, create, incur, assume or otherwise cause or permit to exist any Lien (other than Permitted Liens) securing any Indebtedness upon any of their property or assets, now owned or hereafter acquired, or any income or profits therefrom or assign or convey any right to receive income therefrom, unless all payments due under this Indenture and unless the Notes and the Subsidiary Guarantees, as applicable, are secured on an equal and ratable basis (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes or Subsidiary Guarantee, as the case may be) with the obligations so secured until such time as such obligations are no longer secured by a Lien.

Section 4.10. Dividend and Other Payment Restrictions Affecting Subsidiaries.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries or with respect to any other interest or participation in, or measured by, its profits, or pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; provided that the priority of any preferred stock in receiving dividends or liquidating distributions prior to the payment of dividends or liquidating distributions on common stock shall not be deemed to be a restriction on the ability to make distributions on Capital Stock;

(2) make loans or advances to the Company or any of its Restricted Subsidiaries; or

(3) transfer any of its assets to the Company or any of its Restricted Subsidiaries.

However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements governing Existing Indebtedness, Credit Facilities and Hedging Obligations and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements; provided that such agreements, Credit Facilities, Hedging Obligations and the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue Date;

(3) any instrument governing Indebtedness or Capital Stock, or any other agreement relating to any assets, of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such restriction was created in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the assets of any Person, other than the Person, or the assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(4) (a) customary non-assignment provisions in any contract, license or lease and (b) cash, other deposits, or net worth or similar requirements; in each case, imposed by suppliers or landlords under contracts, in the case of each of subclauses (a) and (b), entered into in the ordinary course of business and consistent with past practices;

(6) any restriction with respect to a Restricted Subsidiary imposed pursuant to an agreement for the sale or other disposition of all or substantially all of the Capital Stock or assets of such Restricted Subsidiary pending the closing of such sale or other disposition;

(7) Permitted Refinancing Indebtedness; provided that the encumbrances or restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(8) Liens securing Indebtedness otherwise permitted to be incurred under the provisions of Section 4.09 (“Liens”) that limit the right of the debtor to dispose of the assets subject to such Liens; and

(9) provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, agreements relating to sale and leaseback transactions, stock sale agreements and other similar agreements entered into in the ordinary course of business.

Section 4.11. Transactions with Affiliates.

(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 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 any such Person (each, an “ Affiliate Transaction ”) if such Affiliate Transaction involves aggregate consideration in excess of $5.0 million, unless:

(1) such 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 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, as evidenced by the delivery of the Officers’ Certificate provided for in clause (2) below; and

67

(2) the Company delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million but less than $25.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above; and

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

(1) any employment, equity award, equity option or equity appreciation agreement, plan agreement or similar compensation arrangement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with past practices and payments pursuant thereto;

(2) fees and compensation paid to, and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries in their capacity as such, to the extent such fees and compensation are reasonable and customary;

Section 4.12. Business Activities.

The Company will not, and will not permit any Restricted Subsidiary to, engage in any line of business activity other than Permitted Businesses, except to such extent as would not be material to the Company and its Subsidiaries taken as a whole.

In the event that at any time (a) the Notes have a Moody’s rating of Baa3 (or the equivalent) or higher or an S&P rating of BBB- (or the equivalent) or higher (each, an “Investment Grade Rating”) and (b) no Default has occurred and is continuing under this Indenture, the Company and its Restricted Subsidiaries will no longer be subject to Section 4.07 (“Restricted Payments”), Section 4.08 (“Incurrence of Indebtedness and Issuance of Preferred Stock”), Section 4.09 (“Liens”), Section 4.10 (“Dividend and Other Payment Restrictions Affecting Subsidiaries”), Section 4.11 (“Transactions with Affiliates”), Section 4.12 (“Business Activities”), Section 4.19 (“Asset Sales”), clauses (a) and (c) of Section 4.20 (“Sale and Leaseback Transactions”), and clause (4) of Section 5.01(a) (“Merger, Consolidation, or Sale of Assets”). The Company will provide prompt written notice to the Trustee of the Company’s determination that a covenant termination under this Section 4.13 has occurred.

Upon the occurrence of an Investment Grade Rating Event, as a result of the elimination of the covenant in Section 4.09 (“Liens”), the covenant described below under Section 4.21 (“Secured Indebtedness”) will apply to the Company and its Restricted Subsidiaries and become effective only upon the occurrence of such an Investment Grade Rating Event.

Section 4.14. Additional Subsidiary Guarantees.

If any Domestic Subsidiary that is not a Guarantor guarantees, assumes or in any other manner becomes liable for Indebtedness of the Company or any Guarantor, then such Domestic Subsidiary will (1) become a Guarantor, (2) execute a supplemental Indenture in the form attached as Exhibit E hereto and deliver an Opinion of Counsel satisfactory to the Trustee and (3) execute an amendment to the Registration Rights Agreement pursuant to which it becomes subject to the obligations of a Guarantor thereunder, in each case, within 10 Business Days of the date on which it so became liable with respect to such Indebtedness; provided that, any Domestic Subsidiary that constitutes an Immaterial Subsidiary shall not be required to become a Guarantor until such time as it ceases to be an Immaterial Subsidiary. Upon the release, termination or

69

satisfaction of such Domestic Subsidiary’s guarantee or assumption of such Indebtedness, or as otherwise provided in this Indenture, that Restricted Subsidiary’s Subsidiary Guarantee shall automatically be released and terminated.

Section 4.15. Designation of Restricted and Unrestricted Subsidiaries.

(a) The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if the Subsidiary meets or would meet the definition of an “Unrestricted Subsidiary” and if no Default shall occur immediately after giving effect to such designation. If a 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 properly designated will be deemed to be an Investment made as of the date of designation and will reduce the amount available for Restricted Payments under paragraphs (a) or (b) of Section 4.07 (“Restricted Payments”) or Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

(b) The Board of Directors of the Company may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if, immediately after giving effect to such designation, a Default would not occur; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if such Indebtedness is permitted under Section 4.08 (“Incurrence of Indebtedness and Issuance of Preferred Stock”), calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period.

Section 4.16. Payments for Consent.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 4.17. Reports.

(1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Company’s independent registered public accounting firm; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports.

70

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each Annual Report on Form 10-K will include a report on the Company’s consolidated financial statements by the Company’s certified independent accountants.

(b) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by paragraph (a) will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

(c) The Company will file a copy of each of the reports referred to in paragraph (a) with the SEC for public availability (unless the SEC will not accept such a filing). If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraphs on its website. Following the consummation of the Exchange Offer contemplated by the Registration Rights Agreement, whether or not required by the SEC, the Company will file a copy of all of the information and reports referred to in clauses (1) and (2) of paragraph (a) with the SEC for public availability within the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. The Company, and to the extent applicable, the Guarantors, will be deemed to have furnished such reports and other information to the Trustee and the Holders of Notes, and, to the extent herein provided, to securities analysts and prospective investors, if it has filed such reports and other information with the SEC using the EDGAR filing system (or any successor filing system), or if such system is not available to the Company, if it has filed such reports and other information on its website, and in each case, such reports and other information are publicly available thereon.

(d) The Company will hold a quarterly conference call for the Holders of the Notes and securities analysts to discuss such financial information no later than 15 Business Days after distribution of such financial information.

(e) The Company and the Guarantors agree that, for so long as any Notes remain outstanding, they will furnish to the Holders of Notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Section 4.18. Offer to Repurchase Upon Change of Control.

(a) If a Change of Control occurs, each Holder of the Notes will have a right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer by the Company (a “ Change of Control Offer ”) on the terms described below. In the Change of Control Offer, the Company will offer a payment in cash (the “ Change of Control Payment ”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional Interest, if any, thereon for the Notes repurchased, to the date of purchase. Within 30 days following any Change of Control, the Company will mail a notice to each Holder of the Notes describing the transaction or transactions that constitute the Change of Control and offering to repurchase the Notes on the 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 mailed (the “ Change of Control Payment Date ”), pursuant to the procedures described below and in such notice.

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 Change of Control provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of this Indenture by virtue of such conflict.

(b) On the Change of Control Payment Date, the Company will, to the extent lawful:

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

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

(3) 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.

The Paying Agent will promptly mail to each Holder of Notes properly tendered pursuant to the Change of Control Offer the Change of Control Payment for such Notes, 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 that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all notes tendered and not withdrawn pursuant to the Change of Control Offer.

Section 4.19. 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 the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents, or any combination thereof.

For purposes of this provision, each of the following will be deemed to be cash:

(B) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents within 180 days following the closing of such Asset Sale, to the extent of the cash or Cash Equivalents received in that conversion;

(C) the Fair Market Value of all forms of consideration other than cash or Cash Equivalents received for all Asset Sales since the Issue Date does not exceed in the aggregate 10.0% of Consolidated Net Worth of the Company at the time each determination is made; and

(D) any Designated Non-cash Consideration, when taken together with all other Designated Non-cash Consideration received pursuant to this clause (D) that is at that time outstanding, not to exceed the greater of $75.0 million and 5.0% of the Company’s Consolidated Net Tangible Assets at the time of the receipt of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value).

Any Asset Sale pursuant to an Involuntary Transfer shall not be required to satisfy the conditions set forth in clauses (1) and (2) of this paragraph (a).

(b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale (including, without limitation, an Involuntary Transfer), the Company or a Restricted Subsidiary of the Company, as the case may be, may apply those Net Proceeds at its option as follows:

The Company or the applicable Restricted Subsidiary will be deemed to have complied with clause (2) or (3) of this paragraph (b) if, within 365 days of such Asset Sale, the Company or such Restricted Subsidiary shall have commenced and not completed or abandoned an expenditure or Investment, or a binding agreement with respect to an expenditure or Investment, in compliance with clause (2) or (3), and that expenditure or Investment is substantially completed within a date one year and six months after the date of such Asset Sale. Pending the final application of any Net Proceeds, the Company will temporarily reduce any Credit Facility or other revolving credit borrowings, or, in the absence of any such borrowings, invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in paragraph (b) of this Section 4.19 will constitute “ Excess Proceeds .” When the aggregate amount of Excess Proceeds exceeds $25.0 million, the Company will, within thirty days thereafter, make an Asset Sale Offer to all Holders of Notes and, to the extent required, all holders of other Indebtedness of the Company 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, to purchase the maximum principal amount of Notes (in integral multiples of $2,000) and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds.

(d) The offer price in any Asset Sale Offer will be equal to 100% of the principal amount of Notes and other pari passu Indebtedness to be purchased or the lesser amount required under agreements governing such other pari passu Indebtedness, plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, and will be payable in cash.

(e) If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not prohibited by this Indenture.

(f) If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(g) The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into or permit to exist any agreement (other than any agreement governing Credit Facilities

74

for Indebtedness permitted to be incurred pursuant to clause (1) of paragraph (b) of Section 4.08 (“Incurrence of Indebtedness and Issuance of Preferred Stock”) that would place any restriction of any kind (other than pursuant to law or regulation) on the ability of the Company to make an Asset Sale Offer.

Section 4.20. Sale and Leaseback Transactions

The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction with a Person other than the Company or a Restricted Subsidiary, as applicable; provided that the Company or any Restricted Subsidiary may enter into such a sale and leaseback transaction if:

(a) the Company or that Restricted Subsidiary, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under Section 4.08 (“Incurrence of Indebtedness and Issuance of Preferred Stock”) hereof and (b) incurred a Lien to secure such Indebtedness pursuant to Section 4.09 (“Liens”) hereof;

(5) failure by the Company or any of its Restricted Subsidiaries to comply with any of the other agreements in this Indenture (other than a failure that is subject to clause (1), (2), (3) or (4) above), and such failure continues for 60 days after the Company’s receipt of written notice of such noncompliance given to it as provided below;

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, if that default:

(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,

77

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;

(7) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $25.0 million (excluding amounts covered by insurance, reimbursement agreements and indemnification agreements), which judgments are not paid, discharged or stayed for a period of 60 days;

(8) except as permitted by this Indenture, any Subsidiary Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason (other than in accordance with the terms of that Guarantee and this Indenture) to be in full force and effect or any Guarantor shall deny or disaffirm its obligations under its Subsidiary Guarantee (other than by reason of the termination of this Indenture or the release of any Subsidiary Guarantee in accordance with this Indenture); and

(9) the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of their Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law:

(A) commences a voluntary case;

(B) consents to the entry of an order for relief against it in an involuntary case;

(C) consents to the appointment of a custodian of it or for all or substantially all of its property;

(D) makes a general assignment for the benefit of its creditors; or

78

(B) appoints a custodian of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of their Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; or

and the order or decree remains unstayed and in effect for 60 consecutive days.

A Default under clause (3), (4) or (5) above will not be an Event of Default until the Trustee or the Holders of not less than 25% in the aggregate principal amount of the outstanding Notes notifies, in writing, the Company of the Default and requests compliance with the specific provision or agreement, as the case may be, that is the subject of such Default, and the Company does not cure such Default within the specified time after receipt of such notice.

Notwithstanding the above, if the Company elects, the sole remedy for a Default or an Event of Default relating to the failure to comply with Section 4.17 (“Reports”), and/or for failure to comply with the requirements of Section 314(a)(1) of the TIA will, for the 60 days after the occurrence of such an Event of Default, consist exclusively of the right to receive additional interest on the Notes at an annual rate equal to 0.25% of the principal amount of the Notes then outstanding over such portion of the 60-day period immediately following such Event of Default during which such Event of Default is continuing (such interest, “ Default Interest ”). In the event the Company does not elect to pay such Default Interest, upon an Event of Default under this Section, the Notes will be subject to acceleration as provided below in Section 6.02 (“Acceleration”). The Default Interest will accrue on all outstanding Notes from and including the date on which an Event of Default relating to a failure to comply with Section 4.17 (“Reports”) and/or for any failure to comply with the requirements of Section 314(a)(1) of the TIA first occurs to, but not including, the 60th day thereafter (or such earlier date on which the Event of Default relating to such failure shall have been cured or waived) and will be payable in the same manner as Additional Interest. On such 60th day (or earlier, if the Event of Default relating to such failure is cured or waived prior to such 60th day) such Default Interest will cease to accrue and the Notes will be subject to acceleration, as provided below in Section 6.02 (“Acceleration”), if the Event of Default is continuing. This provision will not affect the rights of Holders in the event of the occurrence of any other Event of Default.

Section 6.02. Acceleration .

In the case of an Event of Default specified in clause (9) or (10) of Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable

79

immediately without further action or notice. 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.

Section 6.03. Other Remedies .

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or enforce the performance of any provision of the Notes or this Indenture.

The Holders of a majority in principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain exceptions.

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

Section 6.04. Waiver of Past Defaults .

The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of all Holders of the Notes (i) waive any existing Default or Events of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of principal of, or interest or premium or Additional Interest, if any, on, the Notes and (ii) rescind an acceleration and its consequences, if the rescission would not violate with any judgment or decree and if all existing Events of Default have been cured or waived.

Section 6.05. Control by Majority .

Subject to certain limitations, the Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. 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.

Section 6.06. Limitation on Suits .

Subject to Section 7.01 (“Duties of Trustee”), 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 of Notes unless such Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or Additional Interest, if any, when due, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

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

80

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy;

(3) such Holders have offered the Trustee security or indemnity reasonably satisfactory to it against any loss, liability or expense;

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

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

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

Section 6.07. Rights of Holders of Notes to Receive Payment .

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder; provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.

Section 6.08. Collection Suit by Trustee .

If an Event of Default specified in Sections 6.01(1) or (2) (“Events of Default”) hereof occurs and is continuing, the Trustee may recover judgment in its own name and, in the case of the Trustee, as Trustee of an express trust against the Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel.

Section 6.09. Trustee May File Proofs of Claim .

The Trustee shall be authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and

81

shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts due the Trustee under Section 7.07 (“Compensation and Indemnity”) hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 (“Compensation and Indemnity”) hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10. Priorities .

If the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order:

First : to the Trustee, the Paying Agent and the Registrar for amounts due under Section 7.07 (“Compensation and Indemnity”) hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

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

Third : to the Company or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a Record Date and Interest Payment Date for any payment to Holders of Notes pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs .

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

82

Section 6.12. Delay or Omission Not Waiver .

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

ARTICLE VII.

TRUSTEE

Section 7.01. Duties of Trustee .

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

84

Section 7.03. Individual Rights of Trustee .

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest as described under the TIA it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 (“Eligibility; Disqualification”) and 7.11 (“Preferential Collection of Claims Against Company”) hereof.

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 Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it 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 .

If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will mail to Holders of Notes a notice of the Default or Event of Default within 90 days after the Trustee gains knowledge of such continuing Default or Event of Default unless such Default or Event of Default shall have been cured or waived before the giving of such notice. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except in the case of a Default or Event of Default relating to the payment of principal of, or interest or premium, if any, on, the Notes.

Section 7.06. Reports by Trustee to Holders of the Notes .

(a) Within 60 days after each September 15th beginning with the September 15th following the Issue Date, and for so long as Notes remain outstanding, the Trustee will mail to the Holders of the 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 transmit by mail all reports as required by TIA § 313(c).

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

85

Section 7.07. Compensation and Indemnity .

(a) The Company will pay to the Trustee (in its capacity as Trustee and, to the extent it has been appointed as such, Paying Agent and Registrar) (each, an “ Indemnified Party ”) from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a Trustee of an express trust. The Company will reimburse each Indemnified Party promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Indemnified Party’s agents and counsel.

(b) The Company will indemnify the Indemnified Party against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Indemnified Party will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Indemnified Party to so notify the Company will not relieve the Company of its obligations hereunder. The Company will defend the claim and the Indemnified Party will cooperate in the defense. Each Indemnified Party may have separate counsel but the Company will pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c) The obligations of the Company 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.

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

(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 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee, after written request by any Holder who has been a Holder for at least three months, fails to comply with Section 7.10 (“Eligibility; Disqualification”) hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture.

The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the retiring Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 (“Compensation and Indemnity”) hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 (“Compensation and Indemnity”) hereof will continue for the benefit of the retiring Trustee.

87

Section 7.09. Successor Trustee by Merger, etc .

For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Guarantees, the Company 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

89

any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Guarantees will be unaffected thereby.

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 (“Covenant Defeasance”) hereof, the Company has delivered 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;

90

(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 or the granting of Liens to secure such borrowings or any portion thereof) or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91 ^st day after the day of deposit;

(8) the Company must have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

93

(11) to comply with the rules of any applicable securities depositary; and

(12) to conform the text of this Indenture, the Notes or the Subsidiary Guarantees to any provision of the “Description of Notes” included in the Offering Memorandum to the extent that such provision in the “Description of Notes” included in the Offering Memorandum contains text or provisions that are intended to be set forth verbatim in this Indenture, the Notes or Subsidiary Guarantees.

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02(b) (“Rights of Trustee”) hereof, the Trustee will join with the Company and, other than with respect to any supplemental indenture entered into pursuant to Section 4.14 (“Additional Subsidiary Guarantees”), the Guarantors in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02. With Consent of Holders of Notes .

Except as provided below in this Section 9.02, this Indenture, the Notes or the Subsidiary Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). Sections 2.08 (“Outstanding Notes”) and Section 2.09 (“Treasury Notes”) hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.

Without the consent of each Holder affected, an amendment, supplement or wavier may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the percentage in principal amount of such outstanding 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 any of the provisions with respect to the redemption of the Notes (other than the provisions described above under Sections 3.07 (“Optional Redemption”), 4.18 (“Offer to Repurchase Upon Change of Control”) and 4.19 (“Asset Sales”);

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

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

94

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

(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, or interest or premium or Additional Interest, if any, on, the Notes;

(7) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.07 (“Optional Redemption”), 4.18 (“Offer to Repurchase Upon Change of Control”) and 4.19 (“Asset Sales”) hereof);

(8) make any change in the raking or priority of any Note that would adversely affect the Holder of such Note;

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

(10) make any change in the preceding amendment and waiver provisions.

The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

Section 9.03. Compliance with TIA .

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 Company may, but shall not be obligated to, fix a Record Date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a Record Date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such Record Date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such Record Date.

95

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 Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note 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 IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental Indenture until the Board of Directors of the Company approves it. In executing any amended or supplemental Indenture, the Trustee will be entitled to receive and (subject to Section 7.01 (“Duties of Trustee”) hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04 (“Certificate and Opinion as to Conditions Precedent”) hereof, 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 X.

SATISFACTION AND DISCHARGE

Section 10.01. Satisfaction and Discharge .

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

(1) either:

(A) all such Notes theretofore authenticated and delivered, 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 Company or discharged from such trust as provided in this Indenture, 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 or will become due and payable by reason of the mailing of a notice of redemption or otherwise and, the Company 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 such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on such Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and Additional Interest, if any, and accrued interest to the date of maturity or redemption;

96

(2) no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur immediately after giving effect to the deposit and the deposit will not result in a breach of, or constitute a default under, any other material instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(3) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and

(4) the Company has delivered irrevocable instructions to the Trustee under this Indenture 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, nothing in this Section 10.01 will be deemed to discharge those provisions of Section 7.07 (“Compensation and Indemnity”) hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 10.02. Application of Trust Money .

Subject to the provisions of Section 8.05 (“Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions”) hereof, all money deposited with the Trustee pursuant to Section 10.01 (“Satisfaction and Discharge”) hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 10.01 (“Satisfaction and Discharge”) hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.01 (“Satisfaction and Discharge”) hereof; provided that if the Company has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

97

ARTICLE XI.

GUARANTEES

Section 11.01. Guarantee .

(a) Subject to this Article XI, 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 Company hereunder or thereunder, that:

(1) the principal of, premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full, 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, 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 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 their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Subsidiary Guarantee will not be discharged except by complete payment of the obligations contained in the Notes and this Indenture.

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

98

(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, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes of this Subsidiary 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 VI hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Subsidiary 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 Subsidiary Guarantee.

Section 11.02. 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 Subsidiary 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 Subsidiary 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 each 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 XI, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

Section 11.03. Execution and Delivery of Subsidiary Guarantee .

To evidence its Subsidiary Guarantee set forth in Section 11.01 hereof, on the Issue Date each initial Guarantor hereby shall be required to have a notation of such Subsidiary Guarantee substantially in the form attached as Exhibit D hereto endorsed by an Officer of such Guarantor (by manual or facsimile signature) 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 Subsidiary Guarantee set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee.

If an Officer whose signature is on this Indenture or on the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid nevertheless.

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

99

Subsequent to the date of this Indenture, in the event a Restricted Subsidiary is required by Section 4.14 (“Additional Subsidiary Guarantees”) to guarantee the Company’s obligations under the Notes and this Indenture, the Company will cause such Restricted Subsidiary to comply with the provisions of Section 4.14 (“Additional Subsidiary Guarantees”) hereof and this Article XI, to the extent applicable.

Section 11.04. Guarantors May Consolidate, etc., on Certain Terms .

Except as otherwise provided in Section 11.05 (“Releases”) hereof, if the Subsidiary Guarantee of a Guarantor has not been released, such Guarantor may not sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the transferee, resulting or surviving Person), another Person, other than the Company or another Guarantor, unless:

(1) immediately after giving effect to that transaction, no Default exists; and

(2) either:

(A) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger (if other than the Company or another Guarantor) assumes all the obligations of that Guarantor under this Indenture, its Subsidiary Guarantee and the Registration Rights Agreement, pursuant to a supplemental Indenture satisfactory to the Trustee and an amendment to the Registration Rights Agreement; or

(B) the Net Proceeds of such sale or other disposition are applied in accordance with Section 4.19 (“Asset Sales”).

provided , however , that the transfer, sale or other disposition of all or substantially all of the assets of, directly or indirectly, the Guarantors as a whole will be governed by Article V and may be subject to Section 4.18 (“Offer to Repurchase Upon Change of Control”).

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 Subsidiary Guarantee endorsed upon the Notes 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. Such successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof.

Notwithstanding clauses (1) and (2) of this Section 11.04, any Guarantor may merge with another Subsidiary that has no significant assets or liabilities and was incorporated solely for the purpose of reincorporating that Guarantor in another U.S. jurisdiction so long as the amount of the Company’s Indebtedness and the Indebtedness of the Restricted Subsidiaries is not increased as a result of the merger.

100

Section 11.05. Releases .

The Subsidiary Guarantee of a Guarantor will be released:

(1) in connection with any sale or other disposition of all or substantially all of the 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) a Restricted Subsidiary of the Company, if the sale or other disposition complies with Section 4.19 (“Asset Sales”) hereof;

(2) in connection with any sale or other disposition of such amount of Capital Stock as would result in such Guarantor no longer being a Restricted Subsidiary of the Company to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary of the Company, if the sale or other disposition complies with Section 4.19 (“Asset Sales”);

(3) if the Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with Section 4.15 (“Designation of Restricted and Unrestricted Subsidiaries”) hereof;

(4) if the guarantee by a Guarantor of all other Indebtedness of the Company or any other Guarantor is released, terminated or discharged, except by, or as a result of, payment by such Guarantor under such guarantee;

(5) upon Legal Defeasance or Covenant Defeasance in accordance with Article VIII hereof or satisfaction and discharge of this Indenture in accordance with Article X hereof; or

(6) if the Guarantor becomes an Immaterial Subsidiary.

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