Pursuant to Sections 9.1 and 9.2 of the Original Indenture, the Issuers, the Subsidiary Guarantors and the Trustee, the written consent of the Holders of a majority in principal amount of the Securities outstanding having been received with respect to those portions of this Amended and Restated Indenture that require such consent pursuant to Section 9.2 of the Original Indenture, are authorized to amend and restate the terms and provisions of the Original Indenture as set forth in this Amended and Restated Indenture.

The Issuers have furnished the Trustee with (i) an Officers’ Certificate and (ii) an Opinion of Counsel, each of such documents in form and substance reasonably satisfactory to the Trustee and stating that, in the opinion of such signers or such counsel, as applicable, all conditions precedent, if any, provided for in the Original Indenture with respect to this Amended and Restated Indenture have been complied with and that this Amended and Restated Indenture is authorized or permitted by the Original Indenture.

All things necessary to authorize the execution and delivery of this Amended and Restated Indenture and to make this Amended and Restated Indenture, when executed by the parties hereto, a valid and binding amendment of and supplement to the Original Indenture have been done and performed.

Each party hereto agrees to amend and restate the Original Indenture in its entirety as follows for the benefit of the other parties and for the equal and ratable benefit of the Holders of (i) the $200,000,000 aggregate principal amount of the Issuers’ 8 3/4% Senior Subordinated Notes due 2012 issued on the Issue Date (the “Initial Securities”), (ii) if and when issued, an unlimited principal amount of additional 8 3/4% Senior Subordinated Notes due 2012 in a non-registered offering or in a registered offering of the Issuers that may be offered from time to time subsequent to the Issue Date (the “Additional Securities”), including the $75,000,000 aggregate principal amount of the Issuers’ 8 3/4% Senior Subordinated Notes due 2012 (the “May 2003 Additional Securities”) issued on May 30, 2003 and (iii) if and when issued, the Issuers’ 8 3/4% Senior Subordinated Notes due 2012 that may be issued from time to time in exchange for Initial Securities or any Additional Securities in an offer registered under the Securities Act as provided in the Registration Rights Agreement (as hereinafter defined the “Exchange Securities,” and together with the Initial Securities and Additional Securities, the “Securities”).

(1) the sum of:

(a) discounted future net revenues from proved oil and gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with SEC guidelines before any provincial, territorial, state, Federal or foreign income taxes, as estimated by the Company in a reserve report prepared as of the end of the Company’s most recently completed fiscal year for which audited financial statements are available and giving effect to applicable Commodity Agreements, as increased by, as of the date of determination, the estimated discounted future net revenues from

(i) estimated proved oil and gas reserves acquired since such year end, which reserves were not reflected in such year end reserve report, and

2

(ii) estimated oil and gas reserves attributable to upward revisions of estimates of proved oil and gas reserves since such year end due to exploration, development or exploitation activities, in each case calculated in accordance with SEC guidelines,

and decreased by, as of the date of determination, the estimated discounted future net revenues from

(iii) estimated proved oil and gas reserves produced or disposed of since such year end, and

(iv) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since such year end due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated on a pre-tax basis and substantially in accordance with SEC guidelines, in each case as estimated by the Company’s petroleum engineers or any independent petroleum engineers engaged by the Company for that purpose;

(b) the capitalized costs that are attributable to oil and gas properties of the Company and its Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest available annual or quarterly financial statements;

(2) the sum of:

(a) Minority Interests;

(b) any net gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest audited financial statements;

(d) the discounted future net revenues, calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in (a) (i) above, would be necessary to fully satisfy the payment obligations of the Company and its Subsidiaries with respect to Dollar-Denominated Production Payments (determined, if applicable, using the schedules specified with respect thereto).

If the Company changes its method of accounting from the full cost or a similar method to the successful efforts method of accounting, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Company were still using the full cost or a similar method of accounting.

“Adjusted Net Assets” of a Subsidiary Guarantor at any date means the amount by which the fair value of the Properties and assets of such Subsidiary Guarantor exceeds the total amount of liabilities, including, without limitation, contingent liabilities (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date), but excluding liabilities under its Subsidiary Guarantee, of such Subsidiary Guarantor at such date.

For the purposes of this definition, “control” when used with respect to any Person means the power to direct the management and policies of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing.

(a) has Incurred any Indebtedness since the beginning of such period that remains outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated EBITDA and Consolidated Interest Expense (taking into account any Interest Rate Agreements applicable to such Indebtedness) for such period will be calculated after giving effect on a pro forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period (except that in making such computation, the amount of Indebtedness under any revolving credit facility outstanding on the date of such calculation will be computed based on (i) the average daily balance of such Indebtedness during such four fiscal quarters or such shorter period for which such facility was outstanding or (ii) if such facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such facility to the date of such calculation) and the discharge of any other Indebtedness repaid, repurchased, defeased or otherwise discharged with the proceeds of such new Indebtedness as if such discharge had occurred on the first day of such period; or

(b) has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of the period that is no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio involves a discharge of Indebtedness (in each case other than Indebtedness incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and the related commitment terminated), Consolidated EBITDA and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such discharge of such Indebtedness, including with the proceeds of such new Indebtedness, as if such discharge had occurred on the first day of such period;

(2) if since the beginning of such period the Company or any Restricted Subsidiary will have made any Asset Disposition or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Asset Disposition:

(a) the Consolidated EBITDA for such period will be reduced by an amount equal to the Consolidated EBITDA (if positive) directly attributable to the assets which are the subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDA (if negative) directly attributable thereto for such period; and

9

(b) Consolidated Interest Expense for such period will be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

(3) if since the beginning of such period the Company or any Restricted Subsidiary (by merger or otherwise) will have made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary or is merged with or into the Company) or an acquisition of assets, including any acquisition of assets occurring in connection with a transaction causing a calculation to be made hereunder, including a single asset or all or substantially all of an operating unit, division or line of business, Consolidated EBITDA and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of such period; and

(4) if since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) will have made any Asset Disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (2) or (3) above if made by the Company or a Restricted Subsidiary during such period, Consolidated EBITDA and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto as if such Incurrence or discharge, Asset Disposition or Investment or acquisition of assets occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in the reasonable judgment of a responsible financial or accounting officer of the Company (including pro forma expense and cost reductions and any pro forma expense and cost reductions that have occurred or are reasonably expected to occur, in the reasonable judgment of the chief financial officer of the Company (regardless of whether those cost savings or operating improvements could then be reflected in pro forma financial statements in accordance with Regulation S-X promulgated under the Securities Act or any regulation or policy of the Commission related thereto)). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of 12 months).

10

Notwithstanding the preceding sentence, clauses (2) through (5) relating to amounts of a Restricted Subsidiary of a Person will be added to Consolidated Net Income to compute Consolidated EBITDA of such Person only to the extent (and in the same proportion) that the net income (loss) of such Restricted Subsidiary was included in calculating the Consolidated Net Income of such Person and, to the extent the amounts set forth in clauses (2) through (5) are in excess of those necessary to offset a net loss of such Restricted Subsidiary or if such Restricted Subsidiary has net income for such period included in Consolidated Net Income, only if a corresponding amount would be permitted at the date of determination to be dividend to the Company by such Restricted Subsidiary without prior approval (that has not been obtained), pursuant to the terms of its charter and all agreements, instruments, judgments, decrees, orders, statutes, rules and governmental regulations applicable to that Restricted Subsidiary or its stockholders.

(iii) Members of, or participants in, DTC (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by DTC or by the Trustee as the custodian of DTC or under such Global Security, and DTC may be treated by the Issuers, the Trustee and any agent of the Issuers or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the Trustee or any agent of the Issuers or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of a Holder of a beneficial interest in any Global Security.

(iv) In connection with any transfer of a portion of the beneficial interest in a Global Security pursuant to subsection (f) of this Section 2.1 to beneficial owners who are required to hold Definitive Securities, the Securities Custodian shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the beneficial interest in the Global Security to be transferred, and the Issuers shall execute, and the Trustee shall authenticate and deliver, one or more Definitive Securities of like tenor and amount.

(v) In connection with the transfer of an entire Global Security to beneficial owners pursuant to subsection (f) of this Section 2.1, such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Issuers shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations.

(vi) The registered Holder of a Global Security may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

(f) Definitive Securities. (i) Except as provided below, owners of beneficial interests in Global Securities will not be entitled to receive Definitive Securities. If required to do so pursuant to any applicable law or regulation, beneficial owners may obtain Definitive Securities in exchange for their beneficial interests in a Global Security upon written request in accordance with DTC’s and the Registrar’s procedures. In addition, Definitive Securities shall

44

be transferred to all beneficial owners in exchange for their beneficial interests in a Global Security if (a) DTC notifies the Issuers that it is unwilling or unable to continue as depositary for such Global Security or DTC ceases to be a clearing agency registered under the Exchange Act, at a time when DTC is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the Issuers within 90 days of such notice or, (b) the Issuers execute and deliver to the Trustee and Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable or (c) an Event of Default has occurred and is continuing and the Registrar has received a request from DTC.

(iii) In connection with the exchange of a portion of a Definitive Security for a beneficial interest in a Global Security, the Trustee shall cancel such Definitive Security, and the Issuers shall execute, and the Trustee shall authenticate and deliver, to the transferring Holder a new Definitive Security representing the principal amount not so transferred.

SECTION 2.2. Execution and Authentication. One Officer of each of the Issuers shall sign the Securities for the Issuers by manual or facsimile signature. If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless, after giving effect to any exchange of Initial Securities for Exchange Securities.

A Security shall not be valid until an authorized signatory of the Trustee manually authenticates the Security. The signature of the Trustee on a Security shall be conclusive evidence that such Security has been duly and validly authenticated and issued under this Indenture. A Security shall be dated the date of its authentication.

At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate and make available for delivery: (1) Initial Securities for original issue on the Issue Date in an aggregate principal amount of $200,000,000, (2) Additional Securities for original issue and (3) Exchange Securities for issue only in an Exchange Offer pursuant to the Registration Rights Agreement, and only in exchange for Initial Securities or Additional Securities of an equal principal amount, in each case upon a written order of the Issuers signed by two Officers of each of the Issuers or by an Officer and either an Assistant Treasurer or an Assistant Secretary of each of the Issuers (the “Issuers Order”). Such Issuers Order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and whether the Securities are to be Initial Securities, Additional Securities or Exchange Securities.

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Issuers to authenticate the Securities. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent.

45

In case the Issuer or any Subsidiary Guarantor, pursuant to Article IV or Section 10.2, shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of all or substantially all of its Properties and assets to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into which any Issuer or any Subsidiary Guarantor shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee pursuant to Article IV, any of the Securities authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other Securities executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Securities surrendered for such exchange and of like principal amount; and the Trustee, upon Issuers Order of the successor Person, shall authenticate and deliver Securities as specified in such order for the purpose of such exchange. If Securities shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section 2.2 in exchange or substitution for or upon registration of transfer of any Securities, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Securities at the time outstanding for Securities authenticated and delivered in such new name.

SECTION 2.3. Registrar and Paying Agent. The Issuers shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Issuers shall cause each of the Registrar and the Paying Agent to maintain an office or agency in the Borough of Manhattan, The City of New York. The Registrar shall keep a register of the Securities and of their transfer and exchange (the “Note Register”). The Issuers may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Issuers shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuers shall notify the Trustee of the name and address of each such agent. If the Issuers fail to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.7. The Issuers or any of their Restricted Subsidiaries may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Issuers initially appoint the Trustee as Registrar and Paying Agent for the Securities.

SECTION 2.4. Paying Agent to Hold Money in Trust. By no later than 11:00 a.m. (New York City time) on the date on which any principal of or interest on any Security is due and payable, the Issuers shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal or interest when due. The Issuers shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by such Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee in writing of any default by any of the Issuers or any Subsidiary Guarantor in making any such payment. If either Issuer or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and

46

hold it as a separate trust fund. The Issuers at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.4, the Paying Agent (if other than any Issuer or a Subsidiary) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to each Issuer, the Trustee shall serve as Paying Agent for the Securities.

SECTION 2.5. Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, or to the extent otherwise required under the TIA, the Issuers shall furnish to the Trustee, in writing at least five 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 Securityholders.

SECTION 2.6. Transfer and Exchange.

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in, DTC or other Person with respect to the accuracy of the records of DTC or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than DTC) of any notice (including any notice of redemption) or the payment of any amount or delivery of any Securities (or other security or property) under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Securities shall be given or made only to or upon the order of the registered Holders (which shall be DTC or its nominee in the case of a Global Security).

Dear Sirs:

This certificate is delivered to request a transfer of $                 principal amount of the 8 3/4% Senior Subordinated Notes due 2012 (the “Securities”) of Plains Exploration & Production Company and Plains E&P Company (together, the “Issuers”).

Upon transfer, the Securities would be registered in the name of the new beneficial owner as follows:

Address:                                              

Taxpayer ID Number:                         

The undersigned represents and warrants to you that:

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)) purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the Securities not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risk of our investment in the Securities and we invest in or purchase securities similar

50

to the Securities in the normal course of our business. We and any accounts for which we are acting are each able to bear the economic risk of our or its investment.

2. We understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that is two years after the later of the date of original issue and the last date on which the Issuers or any affiliate of the Issuers was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Issuers, (b) pursuant to a registration statement which has been declared effective under the Securities Act, (c) in a transaction complying with the requirements of Rule 144A under the Securities Act, to a person we reasonably believe is a qualified institutional buyer under Rule 144A (a “QIB”) that purchases for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for its own account or for the account of such an institutional “accredited investor,” in each case in a minimum principal amount of Securities of $250,000 or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Issuers and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and that it is acquiring such Securities for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Issuers and the Trustee reserve the right prior to any offer, sale or other transfer prior to the Resale Termination Date of the Securities pursuant to clauses (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to the Issuers and the Trustee.

8 3/4% Senior Subordinated Notes due 2012 (the “Securities”)

Ladies and Gentlemen:

In connection with our proposed sale of $                 aggregate principal amount of the Securities, we confirm that such sale has been effected pursuant to and in accordance with Regulation S under the United States Securities Act of 1933, as amended (the “Securities Act”), and, accordingly, we represent that:

(a) the offer of the Securities was not made to a person in the United States;

(b) either (i) at the time the buy order was originated, the transferee was outside the United States or we and any person acting on our behalf reasonably believed that the transferee was outside the United States or (ii) the transaction was executed in, on or through the facilities of a designated off-shore securities market and neither we nor any person acting on our behalf knows that the transaction has been pre-arranged with a buyer in the United States;

(c) no directed selling efforts have been made in the United States in contravention of the requirements of Rule 903(b) or Rule 904(b) of Regulation S, as applicable; and

(d) the transaction is not part of a plan or scheme to evade the registration requirements of the Securities Act.

In addition, if the sale is made during a restricted period and the provisions of Rule 903(c)(3) or Rule 904(c)(1) of Regulation S are applicable thereto, we confirm that such sale has been made in accordance with the applicable provisions of Rule 903(c)(3) or Rule 904(c)(1), as the case may be.

You and the Issuers are entitled to rely upon this letter and are irrevocably authorized to produce this letter or a copy hereof to any interested party in any administrative or legal proceedings or official inquiry with respect to the matters covered hereby.

SECTION 2.9. Mutilated, Destroyed, Lost or Stolen Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Issuers shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Securityholder (a) satisfies the Issuers or the Trustee within a reasonable time after such Securityholder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuers or Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Issuers, such Holder shall furnish an indemnity bond sufficient in the judgment of the Issuers and the Trustee to protect the Issuers, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced, and, in the absence of notice to the Issuers, any Subsidiary Guarantor or the Trustee that such Security has been acquired by a bona fide purchaser, the Issuers shall execute and upon Issuers’ Order the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Issuers in their discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section 2.9, the Issuers may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) in connection therewith.

Every new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Issuers, any Subsidiary Guarantor (if applicable) and any other obligor upon the Securities, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

The provisions of this Section 2.9 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 2.10. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.10 as not outstanding. A Security ceases to be outstanding in the event an Issuer or a Subsidiary of the Issuers holds the Security, provided, however, that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, the provisions of Section 12.6 shall apply and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Securities are present at a meeting of Holders of

53

Securities for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Securities which a Trust Officer of the Trustee actually knows to be held by the Issuers or an Affiliate of the Issuers shall not be considered outstanding.

If a Security is replaced pursuant to Section 2.9, it ceases to be outstanding unless the Trustee and the Issuers receive proof satisfactory to them that the replaced Security is held by a protected purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.11. Temporary Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities are ready for delivery, the Issuers may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Issuers consider appropriate for temporary Securities. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate Definitive Securities. After the preparation of Definitive Securities, the temporary Securities shall be exchangeable for Definitive Securities upon surrender of the temporary Securities at any office or agency maintained by the Issuers for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Issuers shall execute, and the Trustee shall authenticate and make available for delivery in exchange therefor, one or more Definitive Securities representing an equal principal amount of Securities. Until so exchanged, the Holder of temporary Securities shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Securities.

SECTION 2.12. Cancellation. The Issuers at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and destroy such Securities in accordance with its internal policies including delivery of a certificate (a “Certificate of Destruction”) describing such Securities disposed (subject to the record retention requirements of the Exchange Act). The Issuers may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

SECTION 2.13. Payment of Interest; Defaulted Interest. Interest on any Security which is payable, and is punctually paid or duly provided for, on any interest payment date shall be paid to the Person in whose name such Security (or one or more predecessor

54

Securities) is registered at the close of business on the regular record date for such interest at the office or agency of the Issuers maintained for such purpose pursuant to Section 2.3.

Any interest on any Security which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the regular record date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Securities (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Issuers, at their election in each case, as provided in clause (a) or (b) below:

(a) The Issuers may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuers shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date (not less than 30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest, which date shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Issuers of such Special Record Date, and in the name and at the expense of the Issuers, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 12.2, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

(b) The Issuers may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuers to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section 2.13, each Security delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

55

SECTION 2.14. Computation of Interest. Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 2.15. CUSIP Numbers. The Issuers in issuing the Securities may use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such CUSIP numbers. The Issuers shall promptly notify the Trustee in writing of any change in the CUSIP numbers.

ARTICLE III

Covenants

SECTION 3.1. Payment of Securities. The Issuers shall promptly pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities and in this Indenture. Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture immediately available funds sufficient to pay all principal and interest then due and the Trustee or Paying Agent, as the case may be, is not prohibited from paying money to the Holders on that date pursuant to the terms of this Indenture.

The Issuers shall pay interest on overdue principal at the rate specified therefor in the Securities, and they shall pay interest on overdue installments of interest at the same rate to the extent lawful.

Notwithstanding anything to the contrary contained in this Indenture, the Issuers may, to the extent it is required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal or interest payments hereunder.

SECTION 3.2. SEC Reports. Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, to the extent permitted by the Exchange Act, the Company will file with the SEC, and provide the Trustee and the Holders of the Securities with, the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange Act within the time periods specified therein. In the event that the Company is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Company will nevertheless provide such Exchange Act information to the Trustee and the Holders of the Securities as if the Company were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the time periods specified therein.

56

SECTION 3.3. Limitation on Indebtedness. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, Incur any Indebtedness; provided, however, that the Company and its Restricted Subsidiaries may Incur Indebtedness if on the date thereof:

(1) the Consolidated Coverage Ratio for the Company and its Restricted Subsidiaries is at least 2.50 to 1.00; and

(2) no Default or Event of Default will have occurred and be continuing or would occur as a consequence of Incurring the Indebtedness.

The first paragraph of this Section 3.3 will not prohibit the Incurrence of the following Indebtedness:

(1) Indebtedness of the Company and its Restricted Subsidiaries Incurred under one or more Credit Facilities in an aggregate principal amount outstanding as of the date of such Incurrence under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (i) $600.0 million and (b) 20% of Adjusted Consolidated Net Tangible Assets determined as of the date of the Incurrence of such Indebtedness;

(2) Indebtedness owed to and held by the Company or a Restricted Subsidiary; provided, however, that any subsequent issuance or transfer of any Capital Stock which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of such Indebtedness (other than to the Company or a Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Indebtedness by the obligor thereon;

(3) Indebtedness under the Securities (but not Additional Securities) and the Subsidiary Guarantees;

(4) Indebtedness outstanding on the Issue Date (other than Indebtedness described in clause (1), (2) or (3) of this paragraph);

(5) Indebtedness of a Restricted Subsidiary Incurred and outstanding on or prior to the date on which such Subsidiary was acquired by the Company (other than Indebtedness Incurred in connection with, or to provide all or any portion of the funds or credit support utilized to consummate, the transaction or series of related transactions pursuant to which such Subsidiary became a Restricted Subsidiary or was acquired by the Company);

(6) Refinancing Indebtedness in respect of Indebtedness Incurred pursuant to the first paragraph of this Section 3.3 or pursuant to clauses (3), (4), (5) of this paragraph or this clause (6); provided, however, that to the extent such Refinancing Indebtedness directly or indirectly Refinances Indebtedness

57

of a Subsidiary Incurred pursuant to clause (5) of this paragraph, such Refinancing Indebtedness shall be Incurred only by such Subsidiary or the Company;

(7) Permitted Acquisition Indebtedness;

(8) Indebtedness in respect of purchase money obligations, including Capitalized Lease Obligations, in an aggregate principal amount not to exceed $50.0 million at any one time outstanding;

(9) Hedging Obligations consisting of Interest Rate Agreements directly related to Indebtedness permitted to be Incurred pursuant to this Indenture;

(10) Non-Recourse Debt;

(11) Indebtedness in respect of bid, performance, reimbursement or surety obligations issued by or for the account of the Company or any Restricted Subsidiary in the ordinary course of business, including Guarantees and letters of credit functioning as or supporting such bid, performance, reimbursement or surety obligations (in each case other than for an obligation for money borrowed);

(12) Indebtedness consisting of obligations in respect of purchase price adjustments, indemnities or Guarantees of the same or similar matters in connection with the acquisition or disposition of Property;

(13) Indebtedness under Commodity Agreements and Currency Agreements entered into in the ordinary course of business for the purpose of limiting risks that arise in the ordinary course of business of the Company and its Restricted Subsidiaries;

(14) Any Guarantee by the Company or a Subsidiary of the Company of Indebtedness Incurred pursuant to the first paragraph of this Section 3.3 or pursuant to clause (1), (2), (3), (4), (8), (9), (13) or (15) of this paragraph or pursuant to clause (6) of this paragraph to the extent the Refinancing Indebtedness Incurred pursuant to the first paragraph of this Section 3.3 or pursuant to clauses (3) or (4) of this paragraph; and

(15) Indebtedness in an aggregate principal amount which, when taken together with all other Indebtedness of the Company outstanding on the date of such Incurrence (other than Indebtedness permitted by clauses (1) through (14) above or the first paragraph of this Section 3.3) does not exceed the greater of (x) 2.5% of Adjusted Consolidated Net Tangible Assets determined as of the date of Incurrence of such Indebtedness and (y) $50.0 million.

The Company will not Incur any Indebtedness under the preceding paragraph if the proceeds thereof are used, directly or indirectly, to refinance any Subordinated Obligations of the

58

Company unless such Indebtedness will be subordinated to the Securities to at least the same extent as the Subordinated Obligations.

For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness incurred pursuant to and in compliance with, this Section 3.3:

(1) in the event that Indebtedness meets the criteria of more than one of the types of Indebtedness described in the first and second paragraphs of this Section 3.3, the Company, in its sole discretion, may divide or classify (or later classify, reclassify, divide or redivide all or a portion of) such item of Indebtedness on the date of Incurrence and only be required to include the amount and type of such Indebtedness in one of such clauses; and

(2) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

Accrual of interest, accrual of dividends, the accretion of accreted value, the payment of interest in the form of additional Indebtedness and the payment of dividends in the form of additional shares of Preferred Stock will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 3.3. The amount of any Indebtedness outstanding as of any date shall be (i) the accreted value of the Indebtedness in the case of any Indebtedness issued with original issue discount and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness.

In addition, the Company will not permit any of its Unrestricted Subsidiaries to Incur any Indebtedness or issue any shares of Disqualified Stock, other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary of the Company as of such date (and, if such Indebtedness is not permitted to be Incurred as of such date under this Section 3.3, the Company shall be in Default of this Section 3.3).

For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 3.3, the maximum amount of Indebtedness that the Company may Incur pursuant to this Section 3.3 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the

59

currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

SECTION 3.4. Limitation on Layering. The Issuers will not Incur any Indebtedness if such Indebtedness is subordinate or junior in ranking in any respect to any Senior Indebtedness unless such Indebtedness is Senior Subordinated Indebtedness or is contractually subordinated in right of payment to Senior Subordinated Indebtedness. No Subsidiary Guarantor will incur or allow to remain outstanding any Indebtedness (including Acquired Indebtedness and any indebtedness allowed pursuant to the second paragraph of Section 3.3) other than such Subsidiary Guarantor’s Subsidiary Guarantee, that is subordinated in right of payment to any Guarantor Senior Indebtedness unless such Indebtedness is Guarantor Senior Subordinated Indebtedness or is subordinated in right of payment to Guarantor Senior Subordinated Indebtedness.

SECTION 3.5. Limitation on Restricted Payments. The Company will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to:

(1) declare or pay any dividend or make any distribution on or in respect of its Capital Stock (including any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) except:

(a) dividends or distributions payable in Capital Stock of the Company (other than Disqualified Stock) or in options, warrants or other rights to purchase such Capital Stock of the Company; and

(b) dividends or distributions payable to the Company or a Restricted Subsidiary of the Company (and if such Restricted Subsidiary is not a Wholly-Owned Subsidiary, to its other holders of common Capital Stock on a pro rata basis);

(2) purchase, redeem, retire or otherwise acquire for value any Capital Stock of the Company or any direct or indirect parent of the Company held by Persons other than the Company or a Restricted Subsidiary of the Company (other than in exchange for Capital Stock of the Company (other than Disqualified Stock));

(3) purchase, repurchase, redeem, defease or otherwise acquire or retire for value, prior to scheduled maturity, scheduled repayment or scheduled sinking fund payment, any Subordinated Obligations (other than the purchase, repurchase, redemption or other acquisition of Subordinated Obligations purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of purchase, repurchase, or acquisition); or

(4) make any Restricted Investment in any Person;

60

(any such dividend, distribution, purchase, redemption, repurchase, defeasance, other acquisition, retirement or Restricted Investment referred to in clauses (1) through (4) shall be referred to herein as a “Restricted Payment”), if at the time the Company or such Restricted Subsidiary makes such Restricted Payment:

(a) a Default shall have occurred and be continuing (or would result therefrom); or

(b) the Company is not able to Incur an additional $1.00 of Indebtedness pursuant to the first paragraph of Section 3.3 after giving effect to such Restricted Payment; or

(c) the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made subsequent to the Issue Date would exceed the sum of:

(i) 50% of Consolidated Net Income for the period (treated as one accounting period) from the beginning of the first fiscal quarter commencing after the Issue Date to the end of the most recent fiscal quarter ending prior to the date of such Restricted Payment for which financial statements are in existence (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit);

(ii) the fair market value of any Related Business or assets used or useful in any Related Business to the extent acquired by the Company or a Restricted Subsidiary (including in a merger or consolidation involving the Company or any Restricted Subsidiary) at any time after June 30, 2004 in consideration for Capital Stock (other than Disqualified Stock) of the Company or the aggregate Net Cash Proceeds received by the Company from the issue or sale of its Capital Stock (other than Disqualified Stock) or other capital contributions subsequent to the Issue Date (other than Net Cash Proceeds received from an issuance or sale of such Capital Stock to a Subsidiary of the Company or an employee stock ownership plan, option plan or similar trust to the extent such sale to an employee stock ownership plan, option plan or similar trust is financed by loans from or guaranteed by the Company or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination);

(iii) the amount by which Indebtedness of the Company is reduced on the Company’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to the Issue Date of any Indebtedness of the Company convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Company (less the amount of any cash, or other property,

61

distributed by the Company upon such conversion or exchange); and

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

SECTION 3.8. Limitation on Sales of Assets and Subsidiary Stock. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless:

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Disposition at least equal to the fair market value (as determined in good faith by the Board of Directors in case of an Asset Disposition having a fair market value of $20.0 million or greater) (including as to the value of all non-cash consideration), of the shares and assets subject to such Asset Disposition;

(2) at least 75% of the consideration from such Asset Disposition received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash, Cash Equivalents or Additional Assets; and

(3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company or such Restricted Subsidiary, as the case may be:

(a) to the extent the Company or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of any Senior Indebtedness), to prepay, repay or purchase Senior Indebtedness or Indebtedness (other than any Preferred Stock) of the Company or Secured Indebtedness (other than any Preferred Stock) of a Restricted Subsidiary that is a Subsidiary Guarantor (in each case other than Indebtedness owed to the Company or an Affiliate of the Company) within 360 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; provided, however, that, in connection with any prepayment, repayment or purchase of Indebtedness pursuant to this clause (a), the Company or such Restricted Subsidiary will retire such Indebtedness, and will cause the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or repurchased; and

(b) to the extent the Company or such Restricted Subsidiary elects, to invest in Additional Assets within 360 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash.

67

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

(b) Any Net Available Cash from Asset Dispositions that is not applied or invested as provided in Section 3.8(a)(3) will be deemed to constitute “Excess Proceeds.” On the 361st day after an Asset Disposition (or, if there exists any Senior Indebtedness with similar provisions requiring the Company to make an offer to purchase such Senior Indebtedness, on the 451st day after an Asset Disposition), if the aggregate amount of Excess Proceeds exceeds $10.0 million, the Issuers will be required to make an offer (“Asset Disposition Offer”) to all Holders of Securities and to the extent required by the terms thereof, to all holders of other Senior Subordinated Indebtedness outstanding with similar provisions requiring the Company or the Issuers to make an offer to purchase such Senior Subordinated Indebtedness with the proceeds from any Asset Disposition (“Pari Passu Notes”), to purchase the maximum principal amount of Securities and any such Pari Passu Notes to which the Asset Disposition Offer applies 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 to the date of purchase, in accordance with the procedures set forth in this Indenture or the agreements governing the Pari Passu Notes, as applicable. To the extent that the aggregate amount of Securities and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Issuers may use any remaining Excess Proceeds for general corporate or partnership purposes, subject to the other covenants contained in this Indenture. If the aggregate principal amount of Securities surrendered by Holders thereof and other Pari Passu Notes surrendered by holders or lenders thereof, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Securities to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Securities and Pari Passu Notes. Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

(c)(1) The Asset Disposition Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five Business Days after the termination of the Asset Disposition Offer Period (the “Asset Disposition Purchase Date”), the Issuers will purchase the principal amount of Securities and Pari Passu Notes required to be purchased pursuant to this Section 3.8 (the “Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly tendered, all Securities and Pari Passu Notes validly tendered in response to the Asset Disposition Offer.

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

(3) On or before the Asset Disposition Purchase Date, the Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Securities and Pari Passu Notes or portions of Securities and Pari Passu Notes thereof so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer,

68

or if less than the Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Securities and Pari Passu Notes so validly tendered and not properly withdrawn, in each case in integral multiples of $1,000. The Issuers will deliver to the Trustee an Officers’ Certificate stating that such Securities or portions thereof were accepted for payment by the Issuers in accordance with the terms of this Section 3.8 and, in addition, the Issuers will deliver all certificates and notes required, if any, by the agreements governing the Pari Passu Notes. The Issuers or the Paying Agent, as the case may be, will promptly (but in any case not later than five Business Days after termination of the Asset Disposition Offer Period) mail or deliver to each tendering Holder of Securities or holder or lender of Pari Passu Notes, as the case may be, an amount equal to the purchase price of the Securities or Pari Passu Notes so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Issuers for purchase, and the Issuers will promptly issue a new Security, and the Trustee, upon delivery of an Officers’ Certificate from the Issuers will authenticate and mail or deliver such new Security to such Holder, in a principal amount equal to any unpurchased portion of the Security surrendered; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple of $1,000. In addition, the Company or the Issuers will take any and all other actions required by the agreements governing the Pari Passu Notes. Any Security not so accepted will be promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers will publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date.

(d) For the purposes of this Section 3.8, the following will be deemed to be cash:

(1) the assumption by the transferee of Indebtedness (other than Senior Subordinated Indebtedness, Subordinated Obligations or Disqualified Stock) of the Company or Indebtedness (other than Preferred Stock) of any Restricted Subsidiary of the Company and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition (in which case the Company will, without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with Section 3.8(a)(3)(a) above); and

(2) securities, notes or other obligations received by the Company or any Restricted Subsidiary of the Company from the transferee that are converted promptly by the Company or such Restricted Subsidiary into cash.

(e) The Issuers will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section 3.8. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 3.8, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of any conflict.

SECTION 3.9. Limitation on Affiliate Transactions. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or

69

conduct any transaction (including the purchase, sale, lease or exchange of any Property or the rendering of any service) with any Affiliate of the Company (an “Affiliate Transaction”) unless:

(1) the terms of such Affiliate Transaction are no less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that could be obtained by the Company or the relevant Restricted Subsidiary in a comparable transaction at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate;

(2) in the event such Affiliate Transaction involves aggregate consideration in excess of $20.0 million, the terms of such transaction have been approved by a majority of the members of the Board of Directors of the Company having no personal stake in such transaction, if any (and such majority or majorities, as the case may be, determines that such Affiliate Transaction satisfies the criteria in clause (1) above); and

(3) in the event such Affiliate Transaction involves aggregate consideration in excess of $40.0 million, the Company has received a written opinion from an independent investment banking firm, appraiser or other expert of nationally recognized standing that such Affiliate Transaction is not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s length basis from a Person that is not an Affiliate.

The preceding paragraph will not apply to:

(1) any Restricted Payment (other than a Restricted Investment) permitted to be made pursuant to Section 3.5;

(2) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and stock ownership plans and other reasonable fees, compensation, benefits and indemnities paid or entered into by the Company or its Restricted Subsidiaries in the ordinary course of business to or with officers, directors or employees of the Company and its Restricted Subsidiaries;

70

Parent or its Subsidiaries pursuant to any of the Transition Agreements as in effect on the Issue Date, as these agreements may be amended, modified or supplemented from time to time; provided, however that any future amendment, modification or supplement entered into after the Issue Date will be permitted to the extent that its terms do not adversely affect the rights of any Holders of the Securities as compared to the terms of the agreements in effect on the Issue Date;

(7) any transaction pursuant to the existing agreements between the Company and PAA as in effect on the Issue Date, as these agreements may be amended, modified or supplemented from time to time; provided, however that any future amendment, modification or supplement entered into after the Issue Date will be permitted to the extent that its terms do not adversely affect the rights of any Holders of the Securities as compared to the terms of the agreements in effect on the Issue Date;

(8) the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of any agreement or arrangement in existence on the Issue Date to which the Company or any of its Restricted Subsidiaries is a party on the Issue Date, as these agreements may be amended, modified or supplemented from time to time; provided, however, that any future amendment, modification or supplement entered into after the Issue Date will be permitted to the extent that its terms do not adversely affect the rights of any Holders of the Securities as compared to the terms of the agreements in effect on the Issue Date;

(10) transactions between the Company and any Person, a director of which is also a director of the Company; provided, however, that such director abstains from voting as a director of the Company on any matter involving such other Person;

(11) advances to employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the ordinary course of business; and

(12) any employment, consulting or similar agreement or other compensation arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business of the Company or such Restricted Subsidiary and consistent with the past practice of the Company or such Restricted Subsidiary.

If a Change of Control occurs, each Holder of Securities will have the right to require the Issuers to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount of the Securities plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The Issuers covenant to effect such repayment or obtain such consent and waiver within 30 days following any Change of Control, it being a Default of this Section 3.10 if the Issuers fail to comply with such covenant.

72

The Issuers 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 Issuers and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer.

Compliance with the Suspended Covenants with respect to Restricted Payments made after the time of such withdrawal, downgrade, Default or Event of Default will be calculated in accordance with the terms of Section 3.5 hereof as though such covenant had been in effect during the entire period of time from the date the Securities are issued.

The principal corporate trust office of the Trustee, or if the Trustee’s principal corporate trust office is not located in The City of New York, any other office or agency maintained by the Trustee in The City of New York (the “Corporate Trust Office”), shall be such office or agency of the Issuers, unless the Issuers shall designate and maintain some other office or agency for one or more of such purposes. The Issuers will give prompt written notice to the Trustee of any change in the location of any such office or agency.

The Issuers will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office or agency.

SECTION 3.16. Partnership and Corporate Existence.

SECTION 3.17. Payment of Taxes and Other Claims. The Issuers will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all material taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary and (ii) all lawful claims for labor, materials and supplies, which, if unpaid, might by law become a material liability or lien upon the property of the Issuers or any Restricted Subsidiary, except for any Lien permitted to be incurred pursuant to subsections (3) and (4) of the definition of “Permitted Liens;” provided, however, that the Issuers shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings and for which appropriate reserves, if necessary (in the good faith judgment of management of the Issuers), are being maintained in accordance with GAAP or where the failure to pay or discharge the same would not have a material adverse effect on the ability of the Issuers to perform its obligations under the Securities or this Indenture.

SECTION 3.18. Restrictions on Activities of the Co-Issuer. The Co-Issuer will not hold any material assets, become liable for any material obligations, other than the Securities, or engage in any significant business activities; provided that the Co-Issuer may be a co-obligor with respect to Indebtedness if the Company is the primary obligor of such Indebtedness and the net proceeds of such Indebtedness are received by the Company or one or more of the Company’s Restricted Subsidiaries other than the Co-Issuer. At any time after the Company is a corporation, the Co-Issuer may consolidate or merge with or into the Company or any Restricted Subsidiary.

SECTION 3.19. Payments for Consent. The Issuers and the Restricted Subsidiaries will not, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fees or otherwise, to any Holder of any Securities for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to be paid or is paid to all Holders of the Securities that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment.

SECTION 3.20. Compliance Certificate. The Issuers shall deliver to the Trustee within 120 days after the end of each Fiscal Year of each of the Issuers an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default or Event of Default and whether or not the signers know of any Default or Event of Default that occurred during such period. If they do, the certificate shall describe the Default or Event of Default, its status and what action the Company is taking or proposes to take with respect thereto. The Company also shall comply with TIA § 314(a)(4).

SECTION 3.21. Further Instruments and Acts. Upon the reasonable request of the Trustee, the Issuers will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

75

SECTION 3.22. Statement by Officers as to Default. The Issuers shall deliver to the Trustee, as soon as possible and in any event within 30 days after the Issuers become aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or Default and the action which the Issuers are taking or propose to take in respect thereof.

ARTICLE IV

Successor Company

SECTION 4.1. Merger and Consolidation. The Company will not consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets to, any Person, unless:

(1) the resulting, surviving or transferee Person (the “Successor Company”) will be a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Company (if not the Company) will expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company under the Securities and this Indenture;

(2) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Company or any Subsidiary of the Successor Company as a result of such transaction as having been Incurred by the Successor Company or such Subsidiary at the time of such transaction), no Default or Event of Default shall have occurred and be continuing;

(3) immediately after giving effect to such transaction, the Successor Company would be able to Incur at least an additional $1.00 of Indebtedness pursuant to the first paragraph of Section 3.3;

(4) if the Company is not the continuing obligor under this Indenture, then any Subsidiary Guarantor, unless it is the Successor Company, shall have by supplemental indenture to this Indenture confirmed that its Subsidiary Guarantee of the Securities shall apply to the Successor Company’s obligations under the Indenture and the Securities; and

(5) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture.

For purposes of this Section 4.1, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the Properties and assets of one or more Subsidiaries of the Company, which Properties and assets, if held by the Company instead of

76

such Subsidiaries, would constitute all or substantially all of the Properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the assets of the Company.

The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, but, in the case of a lease of all or substantially all its assets, the Company will not be released from the obligation to pay the principal of and interest on the Securities.

Notwithstanding the foregoing, the Company is permitted to reorganize as a corporation in accordance with the procedures established in this Indenture, and may merge or consolidate with an Affiliate for such purpose; provided that the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such reorganization. Notwithstanding the preceding clause (3), (x) any Restricted Subsidiary of the Company may consolidate with, merge into or transfer all or part of its properties and assets to the Company, and (y) if then a corporation, the Company may merge with an Affiliate solely for the purpose of reincorporating the Company in another jurisdiction to realize tax or other benefits; provided that, in the case of a Restricted Subsidiary that merges into the Company, the Company will not be required to comply with the preceding clause (4).

ARTICLE V

Redemption of Securities

SECTION 5.1. Optional Redemption. The Securities may be redeemed, as a whole or from time to time in part, subject to the conditions and at the redemption prices specified in the form of Securities set forth in Exhibits A and B hereto, which are hereby incorporated by reference and made a part of this Indenture, together with accrued and unpaid interest to the Redemption Date.

SECTION 5.2. Applicability of Article. Redemption of Securities at the election of the Issuers or otherwise, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article V.

SECTION 5.3. Election to Redeem; Notice to Trustee. The election of the Issuers to redeem any Securities pursuant to Section 5.1 shall be evidenced by a resolution of the Board of Directors. In case of any redemption at the election of the Issuers, the Issuers shall, upon not later than the earlier of the date that is 45 days prior to the Redemption Date fixed by the Issuers or the date on which notice is given to the Holders (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 5.4.

77

SECTION 5.4. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities are to be redeemed at any time pursuant to an optional redemption, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the outstanding Securities not previously called for redemption, in compliance with the requirements of the principal securities exchange, if any, on which such Securities are listed, or, if such Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate (and in such manner as complies with applicable legal requirements) and which may provide for the selection for redemption of portions of the principal of the Securities; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than $1,000.

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

SECTION 5.5. Notice of Redemption. Notice of redemption shall be given in the manner provided for in Section 12.2 not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed. The Trustee shall give notice of redemption in the Issuers’ name and at the Issuers’ expense; provided, however, that the Issuers shall deliver to the Trustee, at least 45 days prior to the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice at the Issuers’ expense and setting forth the information to be stated in such notice as provided in the following items.

All notices of redemption shall state:

(1) the Redemption Date,

(2) the redemption price and the amount of accrued interest to the Redemption Date payable as provided in Section 5.7, if any,

(3) if less than all outstanding Securities are to be redeemed, the identification of the particular Securities (or portion thereof) to be redeemed, as well as the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities to be outstanding after such partial redemption,

(4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

78

(5) that on the Redemption Date the redemption price (and accrued interest, if any, to the Redemption Date payable as provided in Section 5.7) will become due and payable upon each such Security, or the portion thereof, to be redeemed, and, unless the Issuers default in making the redemption payment, that interest on Securities called for redemption (or the portion thereof) will cease to accrue on and after said date,

(6) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued interest, if any,

(7) the name and address of the Paying Agent,

(8) that Securities called for redemption (other than a Global Note) must be surrendered to the Paying Agent to collect the redemption price,

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

(10) the paragraph of the Securities pursuant to which the Securities are to be redeemed.

SECTION 5.6. Deposit of Redemption Price. Not later than 11:00 a.m. New York time on the Redemption Date, the Issuers shall deposit with the Trustee or with a Paying Agent (or, if either of the Issuers is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.4) an amount of money sufficient to pay the redemption price of, and accrued interest on, all the Securities which are to be redeemed on that date.

SECTION 5.7. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the redemption price therein specified (together with accrued and unpaid interest, if any, to the Redemption Date), and from and after such date (unless the Issuers shall default in the payment of the redemption price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Issuers at the redemption price, together with accrued and unpaid interest, if any, to the Redemption Date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Securities.

SECTION 5.8. Securities Redeemed in Part. Any Security which is to be redeemed only in part (pursuant to the provisions of this Article V) shall be surrendered at the office or agency of the Issuers maintained for such purpose pursuant to Section 3.15 (with, if the Issuers or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuers and the Trustee duly executed by, the Holder thereof or such Holder’s

79

attorney duly authorized in writing), and the Issuers shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security at the expense of the Issuers, a new Security or Securities, of any authorized denomination as requested by such Holder, in an aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered, provided, that each such new Security will be in a principal amount of $1,000 or integral multiple thereof.

ARTICLE VI

Defaults and Remedies

SECTION 6.1. Events of Default. Each of the following is an “Event of Default”:

(1) default in any payment of interest or additional interest (as required by the Registration Rights Agreement) on any Security when due, continued for 30 days whether or not such payment is prohibited by the provisions described under Article XI;

(2) default in the payment of principal of or premium, if any, on any Security when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise, whether or not such payment is prohibited by Article XI;

(3) failure by the Company to comply with its obligations under Article IV;

(4) failure by each of the Issuers to comply for 30 days after notice with any of its obligations under Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13, 3.15, 3.18 and 3.19 (in each case, other than a failure to purchase Securities, which will constitute an Event of Default under clause (2) above and other than a failure to comply with Article IV which will constitute an Event of Default under clause (3) above);

(5) failure by the Issuers or any Subsidiary Guarantor to comply for 60 days after notice with its other agreements contained in this Indenture;

(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), other than Indebtedness owed to the Company or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists, or is created after the Issue Date, which 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 (“Payment Default”); or

80

(b) results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”);

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 $10.0 million or more;

(7) any Subsidiary Guarantee shall be held in a judicial proceeding to be, or be asserted by the Issuers or any Subsidiary Guarantor, as applicable, not to be, enforceable or valid or shall cease to be in full force and effect (except pursuant to the release or termination of any such Subsidiary Guarantee in accordance with this Indenture);

(8) (a) the Company or Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(i) commences a voluntary case or proceeding;

(ii) consents to the entry of judgment, decree or order for relief against it in an involuntary case or proceeding;

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property;

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

(v) consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against it;

or takes any comparable action under any foreign laws relating to insolvency; or

(b) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(i) is for relief against the Company or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary in an involuntary case;

81

(ii) appoints a Custodian of the Company or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary or for any substantial part of its Property; or

(iii) orders the winding up or liquidation of the Company or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary;

or any similar relief is granted under any foreign laws and the order, decree or relief remains unstayed and in effect for 60 days;

(9) failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for each of the Issuers and their Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $10.0 million (net of any amounts that a reputable and creditworthy insurance company has acknowledged liability for in writing), which judgments are not paid, discharged or stayed for a period of 60 days (the “judgment default provision”).

However, a Default under clauses (4) and (5) of this Section 6.1 will not constitute an Event of Default until the Trustee or the Holders of 25% in principal amount of the outstanding Securities notify the Company and the Trustee in the case of a notice given by the Holders; of the Default and the Company does not cure such Default within the time specified in clauses (4) and (5) of this Section 6.1 after receipt of such notice.

SECTION 6.2. Acceleration. If an Event of Default (other than an Event of Default described in clause (8) of Section 6.1) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Securities to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest will be due and payable immediately. In the event of a declaration of acceleration of the Securities because an Event of Default described in clause (6) of Section 6.1 has occurred and is continuing, the declaration of acceleration of the Securities shall be automatically annulled if the event of default or payment default triggering such Event of Default pursuant to clause (6) of Section 6.1 shall be remedied or cured by the Company or a Restricted Subsidiary of the Company or waived by the holders of the relevant Indebtedness within 20 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the Securities would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal, premium or interest on the Securities that became due solely because of the acceleration of the Securities, have been cured or waived. If an Event of Default described in clause (8) of Section

82

6.1 above occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the Securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the outstanding Securities may waive any or all past defaults (except with respect to nonpayment of principal, premium or interest) and rescind any such acceleration with respect to the Securities and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Securities that have become due solely by such declaration of acceleration, have been cured or waived.

SECTION 6.3. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of (or premium, if any) or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder 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. No remedy is exclusive of any other remedy. All available remedies are cumulative.

SECTION 6.4. Waiver of Past Defaults. The Holders of a majority in principal amount of the then outstanding Securities by notice to the Trustee may (a) waive, by their consent (including, without limitation consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities), an existing Default or Event of Default and its consequences except (i) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest on a Security or (ii) a Default or Event of Default in respect of a provision that under Section 9.2 cannot be amended without the consent of each Securityholder affected and (b) rescind any such acceleration with respect to the Securities and its consequences if rescission would not conflict with any judgment or decree of a court of competent jurisdiction. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

SECTION 6.5. Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Sections 7.1 and 7.2, that the Trustee determines is unduly prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

83

SECTION 6.6. Limitation on Suits. Subject to Section 6.7, a Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

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

(2) Holders of at least 25% in principal amount of the outstanding Securities have requested in writing that the Trustee pursue the remedy;

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

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

(5) the Holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

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

SECTION 6.7. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture (including, without limitation, Section 6.6), the right of any Holder to receive payment of principal of, premium (if any) or interest when due on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, 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 6.8. Collection Suit by Trustee. If an Event of Default specified in clauses (1) or (2) of Section 6.1 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.7.

SECTION 6.9. Trustee May File Proofs of Claim. The Trustee may 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 and the Securityholders allowed in any judicial proceedings relative to the Company, its Subsidiaries or its or their respective creditors or properties and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7. 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 7.7 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

84

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 on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities 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 or property pursuant to this Article VI, it shall pay out the money or property in the following order:

FIRST: to the Trustee for amounts due under Section 7.7;

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

THIRD: to the Issuers or the Subsidiary Guarantors or to such other party as a court of competent jurisdiction may direct.

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days before such record date, the Issuers shall mail to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid.

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 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 the Company, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in outstanding principal amount of the Securities.

SECTION 6.12. Additional Payments. In the case of any Event of Default occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Issuers with the intention of avoiding payment of the premium that the Issuers would have had to pay if the Issuers then had elected to redeem the Securities pursuant to the optional redemption provisions of this Indenture or were required to repurchase the Securities, an equivalent premium shall also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Securities. If an Event of Default occurs prior to July 1, 2007 by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Issuers with the intention of avoiding the prohibition on redemption of the Securities prior to July 1, 2007, the premium specified in this Indenture for the period commencing July 1, 2007 shall also become immediately due and payable to the extent permitted by law upon the acceleration of the Securities.

SECTION 6.13. Waiver of Stay. Each of the Issuers and the Subsidiary Guarantors covenant (to the extent permitted by applicable law) that it will not at any time insist

85

upon, plead or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Issuers or any Subsidiary Guarantor from paying all of any portion of the principal of (premium, if any, on) or interest on the Securities as contemplated herein, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each of the Issuers and the Subsidiary Guarantors hereby expressly waive all benefit or advantage of any such law, and covenants that they will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE VII

Trustee

SECTION 7.1. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security against loss, liability or expense satisfactory to the Trustee in its sole discretion.

(e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuers.

(f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(j) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses (including reasonable attorneys’ fees and expenses) and liabilities that might be incurred by it in compliance with such request or direction.

SECTION 7.2. Rights of Trustee. Subject to Section 7.1:

(a) The Trustee may conclusively rely on any document (whether in its original or facsimile form) reasonably believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate and/or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officers’ Certificate or Opinion of Counsel.

(c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

87

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers, unless the Trustee’s conduct constitutes willful misconduct or negligence.

(e) The Trustee may consult with counsel of its selection, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(f) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by a Trust Officer at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture.

(g) The Trustee is not required to make any inquiry or investigation into facts or matters stated in any document but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee determines to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuers.

(h) The Trustee is not required to take notice or shall not be deemed to have notice of any Default or Event of Default hereunder, unless a Trust Officer of the Trustee has actual knowledge thereof or has received notice in writing of such Default or Event of Default from the Issuers or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, and in the absence of any such notice, the Trustee may conclusively assume that no such Default or Event of Default exists.

(i) The Trustee is not required to give any bond or surety with respect to the performance of its duties or the exercise of its powers under this Indenture.

(j) In the event the Trustee receives inconsistent or conflicting requests and indemnity from two or more groups of Holders of Securities, each representing less than the aggregate principal amount of Notes outstanding required to take any action thereunder, the Trustee, in its sole discretion may determine what action, if any, shall be taken.

(k) The Trustee’s immunities and protections from liability and its right to indemnification in connection with the performance of its duties under this Indenture shall extend to the Trustee’s officers, directors, agents, attorneys and employees. Such immunities and protections and right to indemnification, together with the Trustee’s right to compensation, shall survive the Trustee’s resignation or removal, the discharge of this Indenture and final payments of the Securities.

(l) The permissive right of the Trustee to take actions permitted by this Indenture shall not be construed as an obligation or duty to do so.

SECTION 7.3. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal

88

with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.4. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Issuers’ use of the proceeds from the Securities, and it shall not be responsible for any statement of the Issuer in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

SECTION 7.5. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee shall mail to each Securityholder notice of the Default or Event of Default within the earlier of 90 days after it occurs or 30 days after the Trustee has knowledge of such default. Except in the case of a Default or Event of Default in payment of principal of, premium (if any), or interest on any Security (including payments pursuant to the optional redemption or required repurchase provisions of such Security, if any), the Trustee may withhold the notice if and so long a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Securityholders.

SECTION 7.6. Reports by Trustee to Holders. As promptly as practicable after each May 15, beginning with the May 15, following the date of this Indenture, and for so long as the Securities remain outstanding, the Trustee shall mail to each Securityholder a brief report dated as of such reporting date that complies with TIA § 313(a). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports required by TIA § 313(c).

A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof.

SECTION 7.7. Compensation and Indemnity. The Issuers shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder as the Issuers and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuers shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Securityholders, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Issuers shall indemnify the Trustee against any and all loss, liability, damages, claims or expense (including reasonable attorneys’ fees and expenses) incurred by it without negligence or willful misconduct on its part in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture (including this Section 7.7) and of defending itself against

89

any claims (whether asserted by any Securityholder, the Company or otherwise). The Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the Issuers of their obligations hereunder. The Issuers shall defend the claim and the Trustee shall provide reasonable cooperation at the Issuers’ expense in the defense. The Trustee may have separate counsel and the Issuers shall pay the fees and expenses of such counsel provided that the Issuers shall not be required to pay such fees and expenses if it assumes the Trustee’s defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Issuers and the Trustee in connection with such defense. The Issuers shall not be under any obligation to pay for any written settlement without its consent, which consent shall not be unreasonably delayed, conditioned or withheld. The Issuers need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence.

To secure the Issuers’ payment obligations in this Section 7.7, the Trustee shall have a Lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

The Issuers’ payment obligations pursuant to this Section 7.7 shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in clause (8) of Section 6.1 with respect to the Company, the expenses are intended to constitute expenses of administration under any Bankruptcy Law.

SECTION 7.8. Replacement of Trustee. The Trustee may resign at any time by so notifying the Issuers. The Holders of a majority in principal amount of the then outstanding Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Issuers shall remove the Trustee if:

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

(2) the Trustee is adjudged bankrupt or insolvent;

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

(4) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed by the Issuers or by the Holders of a majority in principal amount of the then outstanding Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Issuers shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.7.

90

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

If the Trustee fails to comply with Section 7.10, unless the Trustee’s duty to resign is stayed as provided in TIA § 310(b), any Securityholder who has been a bona fide Holder of a Security for at least six months may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section 7.8, the Issuers’ obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.

SECTION 7.9. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture.

SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.

SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated.

ARTICLE VIII

Discharge of Indenture; Defeasance

SECTION 8.1. Discharge of Liability on Securities; Defeasance. (a) Subject to Section 8.1(c), when (i)(x) the Issuers deliver to the Trustee all outstanding Securities

91

(other than Securities replaced pursuant to Section 2.9) for cancellation or (y) all outstanding Securities not theretofore delivered for cancellation have become due and payable, whether at maturity or upon redemption or will become due and payable at their Stated Maturity within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption pursuant to Article V hereof by the Trustee in the name and at the expense, of the Issuers; and the Issuers or any Subsidiary Guarantor irrevocably deposits or causes to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders money in U.S. dollars, non-callable U.S. Government Obligations, 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 such Securities not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; (ii) each of the Issuers or any Subsidiary Guarantor has paid or caused to be paid all sums payable under this Indenture and the Securities; and (iii) the Issuers have delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Securities at maturity or the Redemption Date, as the case may be, then the Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Issuers (accompanied by an Officers’ Certificate and an Opinion of Counsel from each stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with) and at the cost and expense of the Issuers.

(b) Subject to Sections 8.1(c) and 8.2, the Issuers at any time may terminate (i) all its obligations under the Securities and this Indenture and all obligations of the Subsidiary Guarantors under the Subsidiary Guarantees and this Indenture (“legal defeasance option”), and after giving effect to such legal defeasance, any omission to comply with such obligations shall no longer constitute a Default or Event of Default or (ii) its obligations under Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13, 3.16, 3.17, 3.18, 3.19, 6.12, and 4.1(3) and the Issuers may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply with such covenants shall no longer constitute a Default or an Event of Default under Section 6.1(3), 6.1(4) and 6.1(5) and the operation of Sections 6.1(6), 6.1(7), 6.1(8) (but only with respect to a Significant Subsidiary or group of Restricted Subsidiaries that would constitute a Significant Subsidiary) and 6.1(9), and the events specified in such Sections shall no longer constitute an Event of Default (clause (ii) being referred to as the “covenant defeasance option”), but except as specified above, the remainder of this Indenture and the Securities shall be unaffected thereby. The Issuers may exercise their legal defeasance option notwithstanding the prior exercise of their covenant defeasance option. If the Issuers exercise their covenant defeasance option, the Issuers may elect to have any Subsidiary Guarantees in effect at such time terminate.

If the Issuers exercise their legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default, and the Subsidiary Guarantees in effect at such time shall terminate. If the Issuers exercise their covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Section 6.1(4), 6.1(5) (as such Section relates to 3.2, 3.3, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13, 3.16, 3.17, and 3.18), 6.1(6), 6.1(7), 6.1(8) (but only with respect to a Significant Subsidiary or a group of

92

Restricted Subsidiaries, that when taken together, would constitute a Significant Subsidiary), or 6.1(9) or because of the failure of the Company to comply with Section 4.1(3).

Upon satisfaction of the conditions set forth herein and upon request of the Issuers, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuers terminate.

(c) Notwithstanding the provisions of Sections 8.1(a) and (b), the Company’s obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.9, 2.10, 2.11, 3.1, 3.15, 3.16, 3.17, 3.19, 3.20, 3.21, 3.22, 6.7, 7.7, 7.8 and in this Article VIII shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.7, 8.4 and 8.5 shall survive.

SECTION 8.2. Conditions to Defeasance. The Issuers may exercise their legal defeasance option or their covenant defeasance option only if:

(1) the Issuers irrevocably deposit in trust with the Trustee for the benefit of the Holders money in U.S. dollars or U.S. Government Obligations, or a combination thereof, for the payment of principal, premium, if any, and interest on the Securities to maturity or redemption, as the case may be;

(2) the Issuers deliver to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal, premium, if any, and interest when due on all the Securities to maturity;

(3) 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 borrowing of funds to be applied to such deposit);

(4) such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a Default under, any material agreement or instrument (other than this Indenture) to which the Issuers or any of their Subsidiaries is a party or by which the Issuers or any of their Subsidiaries is bound;

(5) the Issuers shall each have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) to the effect that (A) the Securities and (B) assuming no intervening bankruptcy of the Issuers between the date of deposit and the 91st day following the deposit and that if a Holder of the Securities is an insider of the Issuers within the meaning of the Bankruptcy Law, after the 366th day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ right generally;

(6) the Issuers deliver to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) to the effect that the trust resulting from the deposit

93

does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940;

(7) in the case of the legal defeasance option, the Issuers shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) in the United States stating that (i) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the Issue Date there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Securityholders will not recognize income, gain or loss for federal income tax purposes as a result of such 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;

(8) in the case of the covenant defeasance option, the Issuers shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) in the United States to the effect that the Securityholders will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and covenant defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and covenant defeasance had not occurred; and

(9) each of the Issuers delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities and this Indenture as contemplated by this Article VIII have been complied with.

SECTION 8.3. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article VIII. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities.

SECTION 8.4. Repayment to Issuers. The Trustee and the Paying Agent shall promptly turn over to the Issuers upon request any excess money, U.S. Government Obligations or securities held by them upon payment of all the obligations under this Indenture.

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Issuers upon request any money held by them for the payment of principal of or interest on the Securities that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Issuers for payment as general creditors.

SECTION 8.5. Indemnity for U.S. Government Obligations. The Issuers shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

94

SECTION 8.6. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article VIII 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 obligations of the Issuers and Subsidiary Guarantors under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article VIII; provided, however, that, if the Issuers have made any payment of interest on or principal of any Securities because of the reinstatement of their obligations, the Issuers shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE IX

Amendments

SECTION 9.1. Without Consent of Holders. The Issuers, the Subsidiary Guarantors and the Trustee may amend this Indenture or the Securities without notice to or consent of any Securityholder:

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

(2) provide for the assumption by a successor corporation, partnership, trust or limited liability company of the obligations of the Issuers under this Indenture;

(3) to provide for uncertificated Securities in addition to or in place of certificated Securities; provided, however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code;

(4) to add or release Subsidiary Guarantees in accordance with the terms of this Indenture;

(5) to secure the Securities;

(6) to add to the covenants of the Company and the Subsidiary Guarantors for the benefit of the Holders or to surrender any right or power herein conferred upon the Company;

(7) to make any change that does not materially adversely affect the rights of any Securityholder; or

(8) to comply with any requirements of the SEC in connection with qualifying, or maintaining the qualification of, this Indenture under the TIA.

95

After an amendment under this Indenture becomes effective, the Company is required to mail to the Holders a notice briefly describing such amendment. However, the failure to give such notice to all the Holders, or any defect therein, will not impair or affect the validity of the amendment and, subject to Sections 6.4 and 6.7, any existing Default or Event of Default (other than a Default or Event of Default in the payment of principal of, premium if any, or interest on, the Securities, except a payment Default resulting from an acceleration that has been rescinded).

SECTION 9.2. With Consent of Holders. The Issuers, the Subsidiary Guarantors and the Trustee may amend this Indenture or the Securities without notice to any Securityholder but with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). However, without the consent of each Securityholder affected, an amendment may not:

(1) reduce the principal amount of Securities whose Holders must consent to an amendment;

(2) reduce the stated rate of or extend the stated time for payment of interest on any Security;

(3) reduce the principal of or extend the Stated Maturity of any Security;

(4) reduce the premium payable upon the redemption or repurchase of any Security or change the time at which any Security may or shall be redeemed or repurchased as described under Article V, Section 3.8, Section 3.10 or any similar provision, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise;

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

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

(7) reduce the relative ranking of any Securities or Subsidiary Guarantees; or

(8) make any change to the amendment provisions which require each Holder’s consent or to the waiver provisions.

However, no amendment may be made to the subordination provisions of this Indenture that adversely affects the rights of any holder of Senior Indebtedness then outstanding unless the holders of such Senior Indebtedness (or any group or representative thereof authorized to give a consent) consent to such change. In addition, any amendment to the subordination provisions of the Indenture that adversely affects the rights of any Holder of the Securities will require the consent of the holders of at least 66 ²/3% in aggregate principal amount of the Securities then outstanding.

96

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof. A consent to any amendment or waiver under this Indenture by any Holder of the Securities given in connection with a tender of such Holder’s Securities will not be rendered invalid by such tender.

After an amendment under this Section becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.2.

SECTION 9.3. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Securities shall comply with the TIA as then in effect.

SECTION 9.4. Revocation and Effect of Consents and Waivers. A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder.

For the purposes of this Indenture, the written consent of the Holder of a Global Security shall be deemed to include any consent delivered by an Agent Member by electronic means in accordance with the Automated Tender Offer Procedures system or other customary procedures of, and pursuant to authorization by, DTC.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall become valid or effective more than 120 days after such record date.

SECTION 9.5. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

SECTION 9.6. Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article IX if the amendment does not adversely affect the

97

rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Sections 7.1 and 7.2) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

ARTICLE X

Subsidiary Guarantee

SECTION 10.1. Subsidiary Guarantee. Each Subsidiary Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Subsidiary Guarantor, to each Holder of the Securities and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest on the Securities and all other monetary obligations of the Issuers under this Indenture (all the foregoing being hereinafter collectively called the “Obligations”). Each Subsidiary Guarantor further agrees (to the extent permitted by law) that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Article X notwithstanding any extension or renewal of any Obligation.

Each Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Issuers of any of the Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Issuers or any other person under this Indenture, the Securities or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations or any of them; (e) the failure of any Holder to exercise any right or remedy against any other Subsidiary Guarantor; or (f) any change in the ownership of the Company.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein constitutes a Guarantee of payment when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Obligations.

Except as expressly set forth in Sections 8.1(b) and 10.2, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder to assert any claim or demand or to

98

enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Issuers or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Issuers to pay any of the Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Subsidiary Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders an amount equal to the sum of (i) the unpaid amount of such Obligations then due and owing and (ii) accrued and unpaid interest on such Obligations then due and owing (but only to the extent not prohibited by law) and except as provided in Section 10.2.

Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor for the purposes of this Subsidiary Guarantee.

Each Subsidiary Guarantor also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or the Holders in enforcing any rights under this Section 10.1.

SECTION 10.2. Limitation on Liability; Termination, Release and Discharge.

(a) The obligations of each Subsidiary Guarantor hereunder will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including, but not limited to, Guarantor Senior Indebtedness) and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law.

(b) Subject to Article IV and Section 3.8, each Subsidiary Guarantor may consolidate with or merge into or sell all or substantially all of its property and assets to the Company or another Subsidiary Guarantor without limitation. Subject to Section 3.8 and Article IV, each Subsidiary Guarantor may consolidate with or merge into or sell all or substantially all its assets to a Person other than the Company or another Subsidiary Guarantor (whether or not Affiliated with the Subsidiary Guarantor), except that if the surviving Person of any such merger or consolidation is a Subsidiary of the Company, such merger, consolidation or sale shall not be permitted unless (i) the Person formed by or surviving any such consolidation or merger assumes all the obligations of such Subsidiary under the Subsidiary Guarantee pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee in respect of the Securities, this Indenture and the Subsidiary Guarantee; (ii) immediately after giving effect to such transaction no covenants under Article III are violated; (iii) immediately after giving effect to such transaction, no Default or Event of Default exists; and (iii) the Issuers deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel addressed to the Trustee with respect to the foregoing matters.

(c) A Subsidiary Guarantor will be deemed released and relieved of its obligations under this Indenture and its Subsidiary Guarantee without any further action required on the part of the Company or such Subsidiary Guarantor upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture.

SECTION 10.3. Limitation of Subsidiary Guarantors’ Liability. Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirm that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law.

100

of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to Section 10.4 hereof, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting such a fraudulent conveyance or fraudulent transfer. This Section 10.3 is for the benefit of the creditors of each Subsidiary Guarantor.

SECTION 10.4. Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, that in the event any payment or distribution is made by any Subsidiary Guarantor (a “Funding Guarantor”) under its Subsidiary Guarantee, such Funding Guarantor will be entitled to a contribution from each other Subsidiary Guarantor (if any) in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to the Securities or any other Subsidiary Guarantor’s obligations with respect to its Subsidiary Guarantee.

SECTION 10.5. Subsidiary Guarantees Subordinated to Guarantor Indebtedness. Each Subsidiary Guarantor covenants and agrees, and each Holder of a Security, by his acceptance of the Subsidiary Guarantees, likewise covenants and agrees, for the benefit of the holders, from time to time, of Guarantor Senior Indebtedness, that the payments by such Subsidiary Guarantor in respect of its Subsidiary Guarantee are subordinated and subject in right of payment, to the extent and in the manner provided in this Article X, to the prior payment in full of all Guarantor Senior Indebtedness of such Subsidiary Guarantor, whether outstanding on the date of this Indenture or thereafter created, incurred, assumed or guaranteed; provided, however, that the Subsidiary Guarantee of such Subsidiary Guarantor, the Indebtedness represented thereby and the payment of the principal of (and premium, if any, on) and the interest on the Securities pursuant to such Subsidiary Guarantee in all respects will rank pari passu with, or prior to, all existing and future unsecured indebtedness (including, without limitation, Indebtedness) of such Subsidiary Guarantor that is subordinated to its Guarantor Senior Indebtedness.

This Article X will constitute a continuing offer to all Persons who, in reliance upon such provisions, become holders of, or continue to hold, Guarantor Senior Indebtedness, and such provisions are made for the benefit of the holders of Guarantor Senior Indebtedness, and such holders are made obligees hereunder and any of them may enforce such provisions.

101

(b) Upon the happening of any event (other than a Subsidiary Guarantor Payment Default) the occurrence of which entitles one or more Persons to accelerate the maturity of any Specified Guarantor Senior Indebtedness (a “Subsidiary Guarantor Non-Payment Default”), and receipt by the applicable Subsidiary Guarantor and the Trustee of written notice thereof from one or more of the holders of such Specified Guarantor Senior Indebtedness or their representative (a “Subsidiary Guarantor Payment Notice”), then, unless and until such Subsidiary Guarantor Non-Payment Default will have been cured or waived in writing or will have ceased to exist or such Specified Guarantor Senior Indebtedness is paid in full or otherwise discharged or the holders (or a representative of the holders) of such Specified Guarantor Senior Indebtedness give their written approval, no payment or distribution will be made by such Subsidiary Guarantor in respect of its Subsidiary Guarantee; provided, however, that these provisions will not prevent the making of any payment for more than 179 days after a Subsidiary Guarantor Payment Notice will have been given after which such Subsidiary Guarantor will resume, (unless otherwise prohibited pursuant to the immediately preceding paragraph) making any and all required payments in respect of its Subsidiary Guarantee, including any missed payments. Notwithstanding the foregoing, not more than one Subsidiary Guarantor Payment Notice will be given with respect to any Subsidiary Guarantee within a period of 360 consecutive days. No Subsidiary Guarantor Non-payment Default that existed or was continuing on the date of delivery of any Subsidiary Guarantor Payment Notice with respect to the Specified Guarantor Senior Indebtedness initiating such Subsidiary Guarantor Payment Notice will be, or can be, made the basis for the commencement of a subsequent Subsidiary Guarantor Payment Notice with respect to such Subsidiary Guarantee.

(c) In the event that, notwithstanding the foregoing, a Subsidiary Guarantor will make any payment in respect of its Subsidiary Guarantee to the Trustee or the Holder of any Security prohibited by the foregoing provisions of this Section 10.6, then and in such event such payment will be paid over and delivered forthwith to the Issuers. In the event that a Subsidiary Guarantor will make any payment in respect of its Subsidiary Guarantee to the Trustee, and the Trustee will receive written notice of a Subsidiary Guarantor Payment Default or a Subsidiary Guarantor Non-payment Default from one or more of the holders of Guarantor Senior Indebtedness (or their representative) prior to making any payment to Holders in respect of the Subsidiary Guarantee and prior to 11:00 a.m. Eastern Time, on the date which is two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose, such payments will be paid over by the Trustee and delivered forthwith to the Issuers.

(c) in the event that, notwithstanding the foregoing provisions of this Section 10.7, any direct or indirect payment or distribution of Properties of such Subsidiary Guarantor of any kind or character, whether in cash, property or securities (other than a payment or distribution in the form of Guarantor Junior Securities), will be received by the Trustee or the Holders before all such Guarantor Senior Indebtedness is paid in full or otherwise discharged, such Properties will be received and held in trust for and will be paid over to the holders of such Guarantor Senior Indebtedness remaining unpaid or their representatives, for application to the payment of such Guarantor Senior Indebtedness until all such Guarantor Senior Indebtedness will have been paid or provided for in full, after giving effect to any concurrent payment or distribution to the holders of such Guarantor Senior Indebtedness.

Each of the Issuers or a Subsidiary Guarantor will give prompt written notice to the Trustee of the occurrence of any insolvency or liquidation proceeding with respect to such Subsidiary Guarantor.

Each Holder, by his acceptance thereof, authorizes and expressly directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article X and appoints the Trustee as his attorney-in-fact for such purpose, including, in the event of any insolvency or liquidation proceeding with respect to any Subsidiary Guarantor, the immediate filing of a claim for the unpaid balance of his Securities pursuant to the related Subsidiary Guarantee in the form required in said proceedings and the causing of said claim to be approved.

SECTION 10.11. Right of Trustee to Hold Guarantor Senior Indebtedness.

(b) any direct or indirect payment or distribution of Properties of each of the Issuers of any kind or character, whether in cash, property or securities (other than from any defeasance trust created pursuant to Article VIII hereof and other than a payment or distribution in the form of Junior Securities), by set-off or otherwise, to which the Holders or the Trustee, on behalf of the Holders, would be entitled but for the provisions of this Article XI, will be paid by the Issuers or by any liquidating trustee or agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the holders of Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, ratably according to the aggregate amounts remaining unpaid on account of the Senior Indebtedness held or represented by each, to the extent necessary to make payment in full in cash or Cash Equivalents of all Senior Indebtedness after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness; and

SECTION 11.3. Suspension Of Payment When Senior Indebtedness In Default.

(a) Unless Section 11.2 hereof will be applicable, the Issuers may not pay principal of, premium if any, or interest on, or other payment obligations in respect of, the Securities or make any deposit pursuant to the provisions described under Article VIII above and may not otherwise purchase, redeem or retire any Securities (collectively, “pay the Securities”) if:

(2) any other default or Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms unless, in either case, the default has been cured or waived and any such acceleration has been rescinded or such Senior Indebtedness has been paid in full in cash or Cash Equivalents.

However, the issuers may pay the Securities if the Issuers and the Trustee receive written notice approving such payment from the Representative of the Senior Indebtedness with respect to which either of the events set forth in clause (1) or (2) of the immediately preceding sentence has occurred and is continuing.

(a) The Issuers will give prompt written notice to the Trustee of any fact known to the Issuers which would prohibit the making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article XI or any other provision of this

109

Indenture, the Trustee will not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Securities, unless and until the Trustee will have received written notice thereof from the Company or one or more of the holders of Senior Indebtedness (or their Representative), with respect to a Payment Default, or one or more of the holders of Designated Senior Indebtedness (or their representatives), with respect to a Non-Payment Event of Default, or from any trustee, fiduciary or agent therefor; and, prior to the receipt of any such written notice, the Trustee, subject to TIA §§ 315(a) through 315(d), will be entitled in all respects to assume that no such facts exist; provided, however, that, if the Trustee will not have received the notice provided for in this Section prior to 11:00 a.m. Eastern Time, on the date which is two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of (and premium, if any, on) or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee will have full power and authority to receive such money and to apply the same to the purpose for which such money was received and will not be affected by any notice to the contrary which may be received by it on or after 11:00 a.m. Eastern Time, two Business Days prior to such payment date.

(b) Subject to TIA §§ 315(a) through 315(d), the Trustee will be entitled to conclusively rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a trustee, fiduciary or agent therefor) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee, fiduciary or agent therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article XI, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee or the Holders, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of Senior Indebtedness and other indebtedness of the Issuers, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XI.

SECTION 11.10. Reliance Of Judicial Order Or Certificate Of Liquidating Agent Bank. Upon any payment or distribution of assets of the Issuers referred to in this Article XI, the Trustee, subject to TIA §§ 315(a) through 315(d), and the Holders will be entitled to rely upon any order or decree entered by any court of competent jurisdiction, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of Senior Indebtedness and other indebtedness of the Issuers, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XI.

SECTION 11.11. Rights Of Trustee As A Holder Of Senior Indebtedness; Preservation Of Trustee’s Rights.

The Trustee in its individual capacity will be entitled to all the rights set forth in this Section 11.11 with respect to any Senior Indebtedness, which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture will

110

deprive the Trustee of any of its rights as such holder. Nothing in this Section 11.11 will apply to claims of, or payments to, the Trustee under or pursuant to Section 11.11 hereof.

SECTION 11.12. Article Applicable To Paying Agents. In case at any time a Paying Agent other than the Trustee will have been appointed by the Issuers and be then acting hereunder, the term “Trustee” as used in this Article XI will in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article XI in addition to or in place of the Trustee; provided, however, that Section 11.11 hereof will not apply to the Issuers or any Affiliate of the Issuers if it or such Affiliate acts as Paying Agent.

SECTION 11.13. No Suspension Of Remedies. Nothing contained in this Article XI will limit the right of the Trustee or the Holders of Securities to take any action to accelerate the maturity of the Securities pursuant to Article VI hereof or to pursue any rights or remedies hereunder or under applicable law, except as provided in Article VI hereof and Section 11.3(c) hereof.

SECTION 11.14. Trust Money Not Subordinated. Notwithstanding anything contained herein to the contrary, payments from cash or the proceeds of U.S. Government Obligations held in trust under Article VIII hereof by the Trustee (or other qualifying trustee) and which were deposited in accordance with the terms of Article VIII hereof and not in violation of Section 11.3 hereof for the payment of principal of (and premium, if any, on) and interest on the Securities will not be subordinated to the prior payment of any Senior Indebtedness or subject to the restrictions set forth in this Article XI, and none of the Holders will be obligated to pay over any such amount to the Issuers or any holder of Senior Indebtedness or any other creditor of the Issuers.

SECTION 11.15. Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Issuers or to any other person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article XI or otherwise. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article XI and no implied covenants or obligations with respect to holders of Senior Indebtedness shall be read into this Indenture against the Trustee.

(2) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee stating that, in the opinion of such counsel, all such conditions precedent have been complied with.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an Officer of an Issuer or any Subsidiary Guarantor may be based, insofar as it relates to legal matters, upon a certificate of opinion of, or representations by, counsel, unless such Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be based, and may state that it is so based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an Officer or Officers of an Issuer or such Subsidiary Guarantor stating that the information with respect to such factual matters is in possession of an Issuer or such Subsidiary Guarantor, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate of opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

SECTION 12.5. Statements Required in Certificate or Opinion. Each certificate or opinion with respect to compliance with a covenant or condition provided for in this Indenture shall include:

(1) a statement that the individual making such certificate or opinion has read such covenant or condition;

(2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

113

(3) a statement that, in the opinion of such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(4) a statement as to whether or not, in the opinion of such individual, such covenant or condition has been complied with.

SECTION 12.6. When Securities Disregarded. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Issuers or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuers shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination.

SECTION 12.7. Rules by Trustee, Paying Agent and Registrar. The Trustee may make reasonable rules for action by, or a meeting of, Securityholders. The Registrar and the Paying Agent may make reasonable rules for their functions.

SECTION 12.8. Legal Holidays. A “Legal Holiday” is a Saturday, a Sunday or other day on which commercial banking institutions are authorized or required to be closed in New York City. If a payment date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. If a regular record date is a Legal Holiday, the record date shall not be affected.

SECTION 12.10. No Recourse Against Others.

Each holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities.

SECTION 12.11. Successors. All agreements of the Company in this Indenture and the Securities shall bind their respective successors. All agreements of the Trustee in this Indenture shall bind its successors.

SECTION 12.12. Multiple Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Indenture.

SECTION 12.13. Qualification of Indenture. The Issuers shall qualify this Indenture under the TIA in accordance with the terms and conditions of the Registration Rights

114

SECTION 12.14. Severability. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.
