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 (i) original issue, up to the aggregate principal amount stated in paragraph 4 of the back of the Notes and (ii) Additional Notes in such amounts as may be specified from time to time without limit, subject to Article 4 hereof.

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

24

the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

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

Section 2.04 Paying Agent to Hold Money in Trust.

The Company 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 by the Paying Agent for the payment of principal, premium or Additional Interest, 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 the 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 and the Company shall otherwise comply with TIA §312(a).

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.

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

Section 2.08 Outstanding Notes.

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

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

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

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

37

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 definitive 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 Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of the canceled Notes in accordance with its standard procedures (subject to the record retention requirement of the Exchange Act). Certification of the disposal of all canceled Notes will be delivered to the Company upon request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation except as otherwise provided in this Indenture.

Section 2.12 Defaulted Interest.

If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus , to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The 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 defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.13 CUSIP and ISIN Numbers.

The Company in issuing the Notes may use “CUSIP” and “ISIN” or other similar numbers, and the Trustee will use CUSIP numbers, ISIN numbers or other similar numbers in notices of redemption or exchange or in Offers to Purchase as a convenience to Holders, the notice to state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption or exchange or Offer to Purchase. The Company will promptly notify the Trustee of any change in the CUSIP or ISIN numbers.

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 amounts of $2,000 or integral multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not $2,000 or an integral multiple of $1,000 in excess thereof, 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 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

Section 3.04 Effect of Notice of Redemption.

purchase price of, and accrued interest and Additional Interest, if any, on, all Notes to be redeemed or purchased.

If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the 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 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

The Asset Sale Offer shall be made to all Holders. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”).

Payment for any Notes so purchased will be made in the same manner as interest payments are made.

(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 surrendered by Holders thereof exceeds the Offer Amount, the Trustee will select the Notes to be purchased in compliance with the requirements of any national securities exchange on which the Notes are listed or, if not listed, on a pro rata basis based on the principal amount of Notes surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof, will be purchased); and

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

On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

(c) For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (or any portion thereof) meets the criteria of more than one of the categories of Permitted Indebtedness described in Sections 4.09(b) (1) through (14) hererof or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company shall, in its sole discretion, classify that item of Indebtedness (or any portion thereof) in any manner that complies with this Section 4.09 and that item of Indebtedness (or any portion thereof) shall be treated as having been incurred pursuant to only one of those clauses or

53

pursuant to Section 4.09(a). The Company may, at any time, change the classification of an item of Indebtedness (or any portion thereof) to any other clause or to the first paragraph hereof; provided that the Company would be permitted to incur that item of Indebtedness (or that portion thereof) pursuant to that other clause or the first paragraph hereof, as the case may be, at the time of reclassification. Accrual of interest, accretion or amortization of original issue discount shall not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09.

Accrual of interest, accretion or amortization of original issue discount will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09.

The Company will not incur any Indebtedness that is subordinate in right of payment to any other Indebtedness of the Company unless it is subordinate in right of payment to the Notes at least to the same extent. The Company will not permit any Guarantor to incur any Indebtedness that is subordinate in right of payment to any other Indebtedness of such Guarantor unless it is subordinate in right of payment to such Guarantor’s Note Guarantee at least to the same extent. For purposes of this Indenture, no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Company or any Guarantor, as applicable, solely by reason of any Liens or Guarantees arising or created in respect thereof or by virtue of the fact that the holders of any secured Indebtedness have entered into intercreditor agreements giving one or more of such holders priority over the other holders in the collateral held by them.

Section 4.10 Asset Sales.

The Company shall not, and shall 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 that 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 therefor received by the Company or the Restricted Subsidiary is in the form of:

(a) cash or Cash Equivalents; or

(b) property or assets that are used or useful in a Permitted Business, or the Capital Stock of any Person engaged in a Permitted Business if, as a result of the acquisition by the Company or any Restricted Subsidiary thereof, that Person becomes a Restricted Subsidiary.

For the purposes of this Section 4.10(2), each of the following shall be deemed to be cash:

(i) any liabilities, as shown on the Company’s or the Restricted Subsidiary’s most recent balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee and any liabilities to the extent owed to the Company or any Affiliate of the Company) that are assumed by the transferee of any such assets pursuant to a written agreement that releases the Company or the Restricted Subsidiary from further liability;

54

(ii) any securities, notes or other obligations received by the Company or the Restricted Subsidiary from the transferee that are converted by the Company or the Restricted Subsidiary into cash or Cash Equivalents within 180 days of their receipt by the Company or the Restricted Subsidiary, but only to the extent of the cash or Cash Equivalents received; and

(iii) any Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries in that Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this clause (iii) that is at that time outstanding, not to exceed 15% of Total Assets at the time of the receipt of that Designated Noncash Consideration, with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value.

The 75% limitation referred to in clause (2) above will not apply to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with subclauses (i), (ii) and (iii) above, is equal to or greater than what the after-tax proceeds would have been had that Asset Sale complied with the aforementioned 75% limitation.

Within 18 months after the receipt of any Net Proceeds from an Asset Sale, the Company or the Restricted Subsidiary, as the case may be, shall apply the Net Proceeds, at its option (or to the extent the Company is required to apply the Net Proceeds pursuant to the terms of the Credit Agreement), to:

(3) repay (a) Indebtedness secured by such assets, (b) Indebtedness of a Restricted Subsidiary that is not a Guarantor (other than Indebtedness owed to the Company or another Restricted Subsidiary), (c) Indebtedness outstanding under Section 4.09(b)(1) or (d) other Pari Passu Indebtedness and, in each case, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto; provided that if the Company or a Guarantor shall repay Pari Passu Indebtedness,

(a) it shall ratably reduce Indebtedness under the Notes by redeeming Notes if the Notes are then redeemable; or

(b) the Company shall make an offer, in accordance with the procedures set forth below for an Asset Sale Offer, to all Holders to purchase at a purchase price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, the Notes that would otherwise be redeemed; or

(4) (a) make an investment in property, make a capital expenditure or acquire assets that, in each case, are used or useful in a Permitted Business; or

(b) acquire Capital Stock of any Person primarily engaged in a Permitted Business if:

(x) as a result of the acquisition by the Company or any Restricted Subsidiary thereof, that Person becomes a Restricted Subsidiary; or

(y) the Investment in that Capital Stock is permitted by clause (6) of the definition of Permitted Investments.

55

Pending the final application of any Net Proceeds, the Company may temporarily reduce Indebtedness or otherwise invest those Net Proceeds in any manner that is not prohibited by this Indenture.

Any Net Proceeds from Asset Sales that are not applied or invested within 18 months after their receipt as provided in the preceding paragraph will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall make an offer (an “Asset Sale Offer”) to all Holders and all holders of other Pari Passu Indebtedness containing provisions similar to those set forth in this Section 4.10 to purchase the maximum principal amount of Notes and such other Pari Passu Indebtedness that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, in accordance with the procedures set forth in this Indenture.

To the extent that any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and such other Pari Passu Indebtedness surrendered by Holders thereof in connection with an Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other Pari Passu Indebtedness to be purchased on a pro rata basis. Upon completion of an offer to purchase, the amount of Excess Proceeds subject to such offer shall no longer be deemed to be Excess Proceeds.

The Company shall 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 pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.09 hereof or this Section 4.10, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under Section 3.09 or this Section 4.10 by virtue of such compliance.

Section 4.11 Transactions with Affiliates.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $10.0 million, unless:

(1) that Affiliate Transaction is on terms that are no less favorable to the Company or that Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or that Restricted Subsidiary with an unrelated Person; and

(2) the Company delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions:

(a) for transactions involving aggregate consideration in excess of $25.0 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that the relevant Affiliate Transaction complies with clause (1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and

56

(b) for transactions involving aggregate consideration in excess of $75.0 million, an opinion that the Affiliate Transaction complies with Section 4.11(a)(1) or that the Affiliate Transaction is fair to the Holders from a financial point of view, issued by an accounting, appraisal or investment banking firm of national standing.

(b) The following shall not be deemed to be Affiliate Transactions and, therefore, shall not be subject to the provisions of Section 4.11(a):

(1) customary directors’ fees, indemnification or similar arrangements or any employment agreement or other compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business (including ordinary course loans to employees not to exceed (a) $5.0 million outstanding in the aggregate at any time and (b) $2.0 million to any one employee) and consistent with the past practice of the Company or that Restricted Subsidiary;

(2) transactions between or among the Company and/or its Restricted Subsidiaries;

(3) any agreement as in effect on the date of this Indenture or any amendment thereto (so long as that amendment is not disadvantageous to the Holders in any material respect) or any transaction contemplated thereby;

(4) Restricted Payments that are permitted under Section 4.07 hereof and any Permitted Investments;

(5) sales of accounts receivable, or participations therein, in connection with any Receivables Facility;

(6) any issuance or sale of Equity Interests (other than Disqualified Stock) of the Company; and

(7) transactions with joint ventures on an arm’s length basis approved by the Board of Directors.

Section 4.12 Liens.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired, unless all obligations under this Indenture and the Note or Note Guarantee, as the case may be, are secured by a Lien on such property or assets on an equal and ratable basis with the obligations secured by such Lien (or, in the case of Subordinated Indebtedness, senior in priority thereto, with the same relative priority as the Notes will have with respect to such Subordinated Indebtedness) until such time as such obligations are no longer secured by a Lien.

57

Section 4.13 Sale and Leaseback Transactions.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any Sale and Leaseback Transaction; provided that the Company or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction if:

(1) the Company or such Restricted Subsidiary, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Indebtedness relating to such Sale and Leaseback Transaction and (b) incurred a Lien to secure such Indebtedness pursuant to Section 4.12 hereof;

(2) the gross cash proceeds of that Sale and Leaseback Transaction are at least equal to the fair market value of the property that is the subject of that Sale and Leaseback Transaction; and

(3) the transfer of assets in that Sale and Leaseback Transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.10 hereof.

Section 4.14 Corporate Existence.

Subject to Section 4.10 and Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect:

(1) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary; and

(2) the rights (charter and statutory), licenses and franchises of the Company and its Restricted Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders.

Section 4.15 Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control Offer”) to each Holder 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 at a purchase price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of repurchase (the “Change of Control Payment”). Within 75 days following any Change of Control, the Company shall or shall cause the Trustee to mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

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

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

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

The Company shall 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.

Section 4.16 Additional Note Guarantees.

If the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary on or after the date hereof, then that newly acquired or created Domestic Subsidiary shall become a Guarantor and execute a supplemental indenture in substantially the form of Exhibit D and, if such newly acquired or created Domestic Subsidiary is a Material Subsidiary, deliver an Opinion of Counsel to the Trustee.

The Company shall not permit any of its Restricted Subsidiaries, directly or indirectly, to guarantee or pledge any assets to secure the payment of any other Indebtedness of the Company or any Guarantor unless such Restricted Subsidiary is a Guarantor or simultaneously executes and delivers to the Trustee an Opinion of Counsel and a supplemental indenture in substantially the form of Exhibit D providing for the guarantee of the payment of the Notes by such Restricted Subsidiary, which guarantee shall be senior to or pari passu with such Subsidiary’s guarantee of such other Indebtedness (unless such other Indebtedness is subordinated Indebtedness, in which case the guarantee of the payment of the Notes must be senior to the guarantee of such other Indebtedness).

Section 4.17 Covenant Suspension.

(a) If the Notes are rated Investment Grade by both Rating Agencies and no Default or Event of Default shall have occurred and then be continuing (the foregoing conditions being referred to collectively as the “Suspension Condition”), the Company and its Restricted Subsidiaries shall not be subject to Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.16 and 5.01(4) (collectively, the “Suspended Covenants”).

(b) If the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants with respect to the Notes as a result of Section 4.17(a) and, subsequently, one or both Rating Agencies withdraw their Investment Grade rating or downgrade the Investment Grade rating assigned to the Notes such that the Notes are no longer rated Investment Grade by both Rating Agencies (the “Reversion Date”), then the Company and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants. Compliance with the Suspended Covenants with respect to Restricted Payments made after the time of such withdrawal or downgrade will be calculated in accordance with Section 4.07 hereof as if such covenant had been in effect from the date hereof. Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default will be deemed to have occurred as result of failure to comply with the Suspended Covenants during any period during which such covenants had been suspended.

(c) The Company shall not be permitted to designate any Material Subsidiary as an Unrestricted Subsidiary while the Suspension Condition is satisfied, unless the Company could have designated such Material Subsidiary as an Unrestricted Subsidiary in compliance with this Indenture assuming the covenants had not been suspended.

(d) The Company will deliver to the Trustee written notice each time the Suspension Condition is satisfied and of each Reversion Date, promptly upon the occurrence thereof but in any event within 10 Business Days after the occurrence thereof.

(a) is caused by a failure to pay Indebtedness at its stated final maturity (after giving effect to any applicable grace period provided in that Indebtedness) (a “Payment Default”); or

62

(b) results in the acceleration of that Indebtedness prior to its stated final maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $50.0 million or more;

(5) failure by the Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million (net of any amounts with respect to which a reputable and creditworthy insurance company has acknowledged liability in writing), which judgments are not paid, discharged or stayed for a period of 60 days;

Section 6.02 Acceleration.

In the case of an Event of Default specified in Section 6.01 (6) or (7), with respect to the Company or any Restricted Subsidiary of the Company that is a Significant Subsidiary, all outstanding Notes shall become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may declare all the Notes to be due and payable immediately by notice in writing to the Company and the Trustee. Upon any such declaration, the Notes shall become due and payable immediately.

The Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Additional Interest, if any, that has become due solely because of the acceleration) have been cured or waived; provided that, in the event of a declaration of acceleration of the Notes because an Event of Default has occurred and is continuing as a result of the acceleration of any Indebtedness described in Section 6.01(4) hereof, the declaration of acceleration of the Notes shall be automatically annulled if the Holders of any Indebtedness described in Section 6.01(4) rescind the declaration of acceleration in respect of that Indebtedness within 30 days of the date of that declaration and if:

(1) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction; and

(2) all existing Events of Default, except non-payment of principal or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived.

Section 6.03 Other Remedies.

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

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

Section 6.04 Waiver of Past Defaults.

Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Additional Interest, if any, or interest on, the Notes (including in connection with an offer to purchase); provided, however , that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every

64

purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

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

Section 6.06 Limitation on Suits.

A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

(1) such Holder gives to the Trustee written notice that an Event of Default is continuing;

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

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

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

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

Section 6.07 Rights of Holders to Receive Payment.

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

Section 6.08 Collection Suit by Trustee.

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

65

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and 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, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall pay out such money, and any money or other property distributable in respect of the Company’s obligations under this Indenture after the occurrence of an Event of Default, in the following order:

First: to the Trustee (including any predecessor Trustee), its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second: to Holders for amounts due and unpaid on the Notes for principal, premium and Additional Interest, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and Additional Interest, 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 payment date for any payment to Holders 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 and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to

66

Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

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.

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 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 and 7.11 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.

Except in the case of a Default or Event of Default in payment of principal of, premium or Additional Interest, if any, or interest on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders.

Section 7.06 Reports by Trustee to Holders.

(a) Within 60 days after each March 15 beginning with the March 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee will mail to the Holders 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

69

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 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). The Company will promptly notify the Trustee when the Notes are listed on any stock exchange.

Section 7.07 Compensation and Indemnity.

(a) The Company will pay to the Trustee from time to time compensation for its acceptance of this Indenture and services hereunder as separately agreed by the Company and the Trustee. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b) The Company and the Guarantors will indemnify the Trustee or any predecessor Trustee and their officers, agents, directors and employees against any and all losses, damages, claims liabilities or expenses including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) 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, or in connection with enforcing the provisions of this Section, except to the extent any such loss, liability or expense is determined by a court of competent jurisdiction to have been caused by its gross negligence or willful misconduct. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c) The obligations of the Company and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of the Notes, the termination for any reason of this Indenture or the resignation or removal of the Trustee.

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

(e) In addition to and without prejudice to its other rights hereunder, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(7) or (8) 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.

70

“Trustee” for purposes of this Section shall include any predecessor Trustee; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

Section 7.08 Replacement of Trustee.

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

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

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

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

(4) the Trustee becomes incapable of acting.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee.

(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 six months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. 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 successor Trustee, at the Company’s expense, will mail a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof.

Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations and the Lien provided for under Section 7.07 hereof will continue for the benefit of the retiring Trustee.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes, Note Guarantees and this Indenture upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall

72

execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

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

(2) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;

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

(4) this Article 8.

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

Section 8.03 Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15 and 4.16 hereof and Sections 5.01(3) and (4) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied and the Note Guarantees will be released (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the 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 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 Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(6) and Section 6.01(9) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

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

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, firm of independent public accountants or similar entity, to pay the principal of, premium and Additional Interest, if any, and interest on, the outstanding Notes on the Stated

73

Maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date;

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, subject to customary assumptions and exclusions, the Holders of the 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 hereof, the Company shall deliver to the Trustee an Opinion of Counsel in the United States confirming that, subject to customary assumptions and exclusions, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default shall have occurred and be continuing 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, insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 123rd day after the date of deposit;

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

(6) the Company shall have delivered to the Trustee an opinion of counsel to the effect that, subject to customary assumptions and exclusions, after the 123rd day following the deposit, the trust funds will not be subject to the effect of Section 547 of the United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law;

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

(8) the Company shall deliver 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.

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

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

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

Notwithstanding anything in this Article 8 to the contrary, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Company.

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

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however , that, if the Company makes any payment of principal of, premium or Additional Interest, if any, or interest on, any

75

Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders.

Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Notes or the Note Guarantees without the consent of any Holder:

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

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

(3) to provide for the assumption of the Company’s obligations to Holders, in the case of a merger or consolidation or sale of all or substantially all of the assets of the Company, or to provide for the assumption of any Guarantor’s obligations under its Note Guarantee, in the case of a merger or consolidation of such Guarantor;

(4) to make any change that would provide any additional rights or benefits to the Holders or that does not, in the good faith judgment of the Company’s Board of Directors, materially adversely affect the legal rights hereunder of any such Holder;

(5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

(6) to provide for the issuance of Additional Notes in accordance with this Indenture;

(7) to provide for additional Note Guarantees;

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

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

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

(11) to conform the text of this Indenture, the Note Guarantees or the Notes to any provision of the “Description of Notes” section of the Offering Memorandum.

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 hereof, the Trustee will join with the Company and

76

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.

After an amendment, supplement or waiver under this Section 9.01 becomes effective, the Company will mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

Section 9.02 With Consent of Holders.

Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or Additional Interest, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 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 waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(2) reduce the principal or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (except as provided above with respect to Sections 3.09, 4.10 and 4.15 hereof);

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

(4) waive a Default or Event of Default in the payment of principal of, or premium, if any, or interest 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);

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

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults;

(7) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10 or 4.15 hereof);

77

(8) amend, change or modify the obligation of the Company to make and consummate a Change of Control Offer in the event of a Change of Control in accordance with Section 4.15 hereof after such Change of Control has occurred, including, in each case, amending, changing or modifying any definition relating thereto;

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

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

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

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

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

Section 9.03 Compliance with Trust Indenture Act.

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

Section 9.04 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to 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 unless it is of the type requiring the consent of each Holder affected. If the amendment, supplement or waiver is of the type requiring the consent of each Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting Holder.

78

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 9 if the amendment or supplement does not 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 hereof) will be fully protected in relying upon, in addition to the documents required by Section 13.04 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.

NOTE GUARANTEES

Section 11.01 Guarantee.

(a) Subject to this Article 11, 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 and Additional Interest, if any, and interest on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

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

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

(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

79

enforce the same, any waiver or consent by any Holder 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 Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the 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 Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

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

Section 11.02 [Reserved].

Section 11.03 Limitation on Guarantor Liability.

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

80

Section 11.04 [Reserved].

Section 11.05 Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 5.01 hereof and this Section 11.05, no Guarantor may consolidate with or merge with or into another Person, whether or not such Guarantor is the surviving Person, unless:

(1) either (a) subject to Section 11.06 hereof, the Person formed by or surviving any such consolidation or merger, if other than the Company or the Guarantor, unconditionally assumes all the obligations of that Guarantor under this Indenture and its Note Guarantee and the Registration Rights Agreement on the terms set forth herein or therein, pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee; or (b) such consolidation or merger complies with Section 4.10 hereof; and

(2) immediately after giving effect to such transaction, no Default or Event of Default exists.

In case of any such consolidation or merger and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee 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. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

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

Section 11.06 Releases.

(a) In the event of a sale or other disposition of all of the Capital Stock of a Guarantor to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the Company, then that Guarantor shall be released and relieved of any obligations under its Note Guarantee; provided that the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of Section 4.10 hereof. Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with Section 4.10 hereof, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Note Guarantee.

(b) Upon designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, that Guarantor will be released and relieved of any obligations under its Note Guarantee.

(c) Upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 12 hereof, each Guarantor will be released and relieved of any obligations under its Note Guarantee.

81

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 11.06 will remain liable for the full amount of principal of and interest and premium and Additional Interest, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 11.

SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

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

(1) either:

(a) all Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation; or

(b) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable, pursuant to an optional redemption notice or otherwise, or may be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name and at the expense of the Company, and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, and Additional Interest, if any, and accrued interest to the date of maturity or redemption, as the case may be; and

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

In addition, the Company shall deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subsection (b) of clause (1) of this Section 12.01, the provisions of Sections 12.02 and 8.06 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Upon compliance with the foregoing the Trustee will, upon request, acknowledge the satisfaction and discharge of this Indenture.

82

Section 12.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium and Additional Interest, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 12.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof; provided that if the Company has made any payment of principal of, premium or Additional Interest, 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.

The Trustee shall have the right, but shall not be required, to rely upon and comply with instructions and directions sent by e-mail, facsimile and other similar unsecured electronic methods by persons reasonably believed by the Trustee to be authorized to give instructions and directions on behalf of the Company.
