(3) whether any other transaction (including any Investment or Restricted Payment) undertaken or proposed to be undertaken in connection with such Limited Condition Transaction complies with the covenants or agreements contained in this Indenture or the Notes; and

(4) any calculation of the Consolidated Leverage Ratio, Fixed Charge Coverage Ratio, Consolidated Net Income, and/or Consolidated Cash Flow and/or Adjusted Consolidated Net Tangible Assets and, whether a Default or Event of Default exists in connection with the foregoing,

at the option of the Partnership, the date that the definitive agreement (or other relevant definitive documentation) for such Limited Condition Transaction is entered into (the “Transaction Agreement Date”) may be used as the applicable date of determination, as the case may be, in each case with such pro forma adjustments as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of “Fixed Charge Coverage Ratio” and if the Partnership or the Restricted Subsidiaries could have taken such action on the relevant Transaction Agreement Date in compliance with the applicable ratios or other provisions, such provisions shall be deemed to have been complied with. For the avoidance of doubt, if the Partnership elects to use the Transaction Agreement Date as the applicable date of determination in accordance with the foregoing, (a) such election may not be revoked, (b) any fluctuation or change in the Consolidated

39

Leverage Ratio, Fixed Charge Coverage Ratio, Consolidated Net Income, Consolidated Cash Flow or Adjusted Consolidated Net Tangible Assets of the Partnership, the target business, or assets to be acquired subsequent to the Transaction Agreement Date and prior to the consummation of such Limited Condition Transaction, will not be taken into account for purposes of determining whether any Investment, Restricted Payment, Indebtedness, Disqualified Stock, Preferred Stock or Lien that is being made, incurred or issued in connection with such Limited Condition Transaction is permitted to be made, incurred or issued or in connection with compliance by the Partnership or any of the Restricted Subsidiaries with any other provision of this Indenture or the Notes or any other action or transaction undertaken in connection with such Limited Condition Transaction and (c) until such Limited Condition Transaction is consummated or the definitive agreements related thereto are terminated, such Limited Condition Transaction and all transactions proposed to be undertaken in connection therewith (including the making of any Restricted Payment, or Investments, or the incurrence of Indebtedness and Liens) will be given pro forma effect when determining compliance of other transactions (including the making of any Restricted Payment, or Investments, or the incurrence or issuance of Indebtedness, Disqualified Stock, Preferred Stock and Liens unrelated to such Investment, acquisition or repayment, repurchase or refinancing of Indebtedness) that are consummated after the Transaction Agreement Date and on or prior to the consummation of such Limited Condition Transaction and any such transactions (including any incurrence or issuance of Indebtedness, Disqualified Stock or Preferred Stock and the use of proceeds thereof) will be deemed to have occurred on the Transaction Agreement Date and outstanding thereafter for purposes of calculating any baskets or ratios under this Indenture after the date of such agreement and before the consummation of such Limited Condition Transaction; provided that for purposes of any such calculation of the Fixed Charge Coverage Ratio, Fixed Charges will be calculated using an assumed interest rate for the Indebtedness to be incurred in connection with such Limited Condition Transaction based on the indicative interest margin contained in any financing commitment documentation with respect to such Indebtedness or, if no such indicative interest margin exists, as reasonably determined by the Partnership in good faith. Each item of Indebtedness, Disqualified Stock or Preferred Stock that is incurred or issued, each Lien incurred and each other transaction undertaken will be deemed to have been incurred, issued or taken first, to the extent available, pursuant to the relevant Fixed Charge Coverage Ratio or Consolidated Leverage Ratio test.

(b) Notwithstanding anything herein to the contrary, if the Partnership or any of its Restricted Subsidiaries (x) incurs Indebtedness, issues Disqualified Stock or Preferred Stock, creates Liens, makes Asset Sales, makes Investments, makes Restricted Payments, designates any Subsidiary as a Restricted Subsidiary or an Unrestricted Subsidiary or repays any Indebtedness, Disqualified Stock or Preferred Stock in connection with any Limited Condition Transaction under a ratio-based basket and (y) incurs Indebtedness, issues Disqualified Stock or Preferred Stock, creates Liens, makes Asset Sales, Investments or Restricted Payments, designates any as a Restricted Subsidiary or an Unrestricted Subsidiary or repays any Indebtedness, Disqualified Stock or Preferred Stock in connection with any Limited Condition Transaction under a non-ratio-based basket (which shall occur within five (5) Business Days of the events in clause (x) above), then the applicable ratio will be calculated with respect to any such action under the applicable ratio-based basket without regard to any such action under such non-ratio-based basket made in connection with such Limited Condition Transaction. In addition, compliance with any requirement relating to absence of Default or Event of Default may be determined as of the Transaction Agreement Date and not as of any later date as would otherwise be required under this Indenture.

THE NOTES

Section 2.01 Form and Dating.

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Issuers, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

(b) Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

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

Section 2.02 Execution and Authentication.

At least one Officer must sign the Notes for each of the Issuers by manual, facsimile or electronically transmitted signature.

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

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

41

The Trustee will, upon receipt of a written order of the Issuers signed by an Officer of each Issuer (an “Authentication Order”), authenticate (i) the Initial Notes for original issue in the aggregate principal amount of $600.0 million, and (ii) thereafter any Additional Notes that may be validly issued under this Indenture. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuers pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

The Trustee shall also authenticate and deliver Notes at the times and in the manner specified in Section 2.06, Section 2.07, Section 2.10, Section 3.06, Section 3.09, Section 4.15 and Section 9.04.

Any issuance of Additional Notes is subject to all of the covenants in this Indenture, including Section 4.09.

With respect to any Additional Notes, the Issuers shall set forth in an Officers’ Certificate, a copy of which shall be delivered to the Trustee at or prior to original issuance thereof, the following information:

(a) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

(b) the issue price, the issue date (and the corresponding date from which interest shall accrue thereon and the first interest payment date therefor) and the CUSIP and/or ISIN number of such Additional Notes; and

(c) whether such Additional Notes shall be subject to the restrictions on transfer set forth in Section 2.06 relating to Restricted Global Notes and Restricted Definitive Notes.

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

The Initial Notes and the Additional Notes shall be treated as a single class for all purposes under this Indenture; provided that if any such Additional Notes are not fungible with the existing Notes for United States federal income tax purposes, such Additional Notes will have a separate CUSIP number from the existing Notes. Holders of the Initial Notes and the Additional Notes will vote and consent together on all matters to which such Holders are entitled to vote or consent as one class, and none of the Holders of the Initial Notes and the Additional Notes shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

42

Section 2.03 Registrar and Paying Agent.

The Issuers will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar for the Notes will keep a register of the Notes and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The Issuers will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Partnership or any of the Partnership’s Subsidiaries may act as Paying Agent or Registrar.

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

The Issuers initially appoint the Trustee to act as the Registrar and Paying Agent for the Notes (at its office indicated in the definition of Corporate Trust Office of the Trustee in Section 1.01 hereof) and to act as Custodian with respect to the Global Notes. In acting hereunder and in connection with the Notes, the Paying Agent and the Registrar shall act solely as agents of the Issuers, and will not thereby assume any fiduciary duty or other obligations towards or relationship of agency or trust for or with any Holder of the Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

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

Section 2.05 Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Issuers will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders.

Section 2.06 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Issuers for Definitive Notes if:

(1) the Depositary notifies the Issuers (A) that it is unwilling or unable to continue to act as Depositary or (B) that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuers within 90 days after the date of such notice from the Depositary;

43

(2) the Issuers, at their option but subject to the Depositary’s requirements, notify the Trustee in writing that they elect to cause the issuance of the Definitive Notes; or

(3) there has occurred and is continuing an Event of Default and the Depositary notifies the Trustee of its decision to exchange such Global Note for Definitive Notes.

Upon the occurrence of the preceding events in (1), (2) or (3) above, Definitive Notes of shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or (c) hereof. Whenever any provision herein refers to issuance by the Issuers and authentication and delivery by the Trustee of a new Note in exchange for the portion of a surrendered Note that has not been redeemed or repurchased, as the case may be, in lieu of the surrender of any Global Note and the issuance, authentication and delivery of a new Global Note in exchange therefor, the Trustee or the Depositary at the direction of the Trustee may endorse such Global Note to reflect a reduction in the principal amount represented thereby in the amount of Notes so represented that have been so redeemed or repurchased.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Participants and Indirect Participants shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary or by the Trustee as the Custodian with respect to the Global Notes, and the Issuers, the Trustee and any agent of the Issuers or the Trustee shall be entitled to treat the Depositary as the absolute owner of such Global Note 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 the Depositary or impair, as between the Depositary and its Participants or the Indirect Participants, the operation of customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Note. Subject to the provisions of this Section 2.06 and Section 12.16, the Holder of a Global Note shall be entitled to grant proxies and otherwise authorize any Person, including Participants and Indirect Participants and Persons that may hold interests through such Persons, to take any action that a Holder of Notes is entitled to take under this Indenture or the Notes. Beneficial interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(1) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend. Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(1).

44

Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.06(h) hereof.

45

and, in each such case set forth in this Section 2.06(b)(4), if the Registrar so requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Registrar to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act.

If any such transfer is effected pursuant to this Section 2.06(b)(4) at a time when an Unrestricted Global Note has not yet been issued, the Issuers shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred pursuant to this Section 2.06(b)(4).

(h) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for beneficial interests in another Global Note or Definitive Notes, or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(i) General Provisions Relating to Transfers and Exchanges.

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

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuers and/or the Trustee may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.04 hereof).

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

(4) Neither the Registrar nor the Issuers will be required:

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

(B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(6) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof.

(7) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by electronic image scan.

(8) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, 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 Notes 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 purchase) or the payment of any amount or delivery of any Notes (or other security or property) under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Notes 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 Note). The rights of beneficial owners in any Global Note shall be exercised only through DTC subject to the applicable rules and procedures of DTC. The Trustee may rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners. The Trustee and each Agent shall be entitled to rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its member, Depositary participants and any beneficial owners. The Trustee and each Agent shall be entitled to deal with the Depositary, and any nominee thereof, that is the registered holder of any Global Note for all purposes of this Indenture relating to such Global Note (including the payment of principal, premium, if any, and interest and additional amounts, if any, and the giving of instructions or directors by or to the owner or holder of a beneficial ownership interest in such Global Note) as the sole holder of such Global Note and shall have no obligations to the beneficial owners thereof.

Neither the Registrar nor the Trustee shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed

56

under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among DTC participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. Neither the Trustee nor any of its agents shall have any responsibility for any actions taken or not taken by DTC.

(10) The transferor of any Note shall provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Code. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information. In connection with any proposed exchange of a Note that is not a Global Note for a Global Note, the Issuers or the Depositary shall be required to provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Code. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

Section 2.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Issuers and the Trustee and the Issuers receive evidence to their satisfaction of the destruction, loss or theft of any Note, and such other reasonable requirements as may be imposed by the Issuers as permitted by Section 8-405 of the Uniform Commercial Code have been satisfied, then, in the absence of notice to the Issuers or the Trustee that such Note has been acquired by a “protected purchaser” within the meaning of Section 8-405 of the Uniform Commercial Code, the Issuers will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. An indemnity, security and/or indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect each of the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers may charge for their expenses in replacing a Note.

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

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the Note; however, Notes held by the Partnership or a Subsidiary of the Partnership shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

57

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser within the meaning of Section 8-405 of the Uniform Commercial Code.

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

If the Paying Agent (other than the Partnership, a Subsidiary or an Affiliate of any thereof) holds, by 11:00 a.m. Eastern Time on a redemption date or other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

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

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuers considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers will execute and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee will authenticate definitive Notes in exchange for temporary Notes.

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

Section 2.11 Cancellation.

The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes in accordance with its internal policies and customary procedures (subject to the record retention requirement of the Exchange Act). The Issuers may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation.

58

Section 2.12 Defaulted Interest.

If the Issuers default in a payment of interest on the Notes, they will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof; provided that no special record date shall be required with respect to defaulted interest paid within the applicable grace period. The Issuers will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuers will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) will deliver or cause to be delivered to Holders of Notes a notice that states the special record date, the related payment date and the amount of such interest to be paid. The Trustee will have no duty whatsoever to determine whether any Defaulted Interest is payable or the amount thereof.

Section 2.13 Computation of Interest.

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

Section 2.14 CUSIP Numbers.

The Issuers in issuing the Notes may use “CUSIP” numbers (if then generally in use). The Trustee will not be responsible for the use of CUSIP numbers, and the Trustee makes no representation as to their correctness as printed on any Note or notice to Holders. The Issuers will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

ARTICLE 3

REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

If the Issuers elect to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, they must furnish to the Trustee, at least five Business Days (or such shorter time as may be acceptable to the Trustee) prior to the giving of notice of a redemption, an Officers’ Certificate setting forth:

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

(b) the redemption date;

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

(d) the redemption price (if then determined and otherwise the method of determination).

59

Section 3.02 Selection of Notes to Be Redeemed.

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2 hereof, by such method as DTC or its nominee or successor may require) unless otherwise required by law or applicable stock exchange or depositary requirements. Notwithstanding the foregoing, no Notes of $2,000 or less can be redeemed in part.

The Trustee will promptly notify the Issuers in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03 Notice of Redemption.

At least 10 days but not more than 60 days before a redemption date, the Issuers will mail or cause to be mailed by first class mail (or sent electronically if DTC is the recipient) a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be given more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 11 hereof.

The notice will identify the Notes (including the CUSIP number) to be redeemed and will state:

(a) the redemption date;

(b) the redemption price (if then determined and otherwise the method of determination);

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

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

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

(f) that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

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

60

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

(i) any conditions precedent to the redemption.

At the Issuers’ request, the Trustee will give the notice of redemption in the Issuers’ names and at their expense; provided, however, that the Officers’ Certificate delivered to the Trustee pursuant to Section 3.01 hereof requests that the Trustee give such notice and sets forth the information to be stated in such notice as provided in the preceding paragraph.

If such redemption is subject to the satisfaction of one or more conditions precedent, the related notice shall describe each such condition, and if applicable, shall state that, in the Issuers’ discretion, the date of redemption may be delayed until such time as any or all such conditions shall be satisfied or waived (provided that in no event shall such date of redemption be delayed to a date later than 60 days after the date on which such notice was mailed or delivered, including by electronic transmission), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the date of redemption, or by the date of redemption as so delayed. The Issuers shall provide written notice of the delay of such date of redemption or the rescission of such notice of redemption to the Trustee no later than 10:00 a.m. Eastern Time (subject to DTC procedures) on the date prior to the date of redemption. Upon receipt of such notice of the delay of such date of redemption or the rescission of such notice of redemption, such date of redemption shall be automatically delayed or such notice of redemption shall be automatically rescinded, as applicable, and the redemption of the Notes to be redeemed shall be automatically delayed or rescinded and cancelled, as applicable, as provided in such notice.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed or given in accordance with Section 3.03 hereof, Notes called for redemption will become irrevocably due and payable (subject to Section 3.03) on the redemption date at the redemption price, subject to satisfaction of any condition specified with respect to such redemption.

Section 3.05 Deposit of Redemption Price.

No later than 11:00 a.m. Eastern Time on the redemption date, the Issuers will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of, and accrued interest, if any, on all Notes to be redeemed on that date. The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption price of, and accrued interest, if any, on all Notes to be redeemed.

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

61

Section 3.06 Notes Redeemed in Part.

Upon surrender of a Note that is redeemed in part, the Issuers will issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee will authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Issuers will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer.

63

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

Upon the commencement of an Asset Sale Offer, the Issuers will send, in accordance with Applicable Procedures, or by first class mail (as applicable), a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(a) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;

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

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

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

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

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

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

(h) that, if the aggregate principal amount of Notes surrendered by Holders thereof exceeds the Offer Amount allocated to the purchase of Notes in the Asset Sale Offer, the Trustee will select the Notes and the Issuers will select such other pari passu Indebtedness to be purchased on a pro rata basis (except that any Notes represented by a Global Note shall be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law) based on the principal amount of Notes or such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Issuers so that only Notes in minimum denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and

64

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

On or before the Purchase Date, the Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Notes or portions thereof tendered pursuant to the Asset Sale Offer and required to be purchased pursuant to this Section 3.09 and Section 4.10 hereof, or if Notes in an aggregate principal amount less than the Offer Amount allocated to the purchase of Notes in the Asset Sale Offer have been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Issuers in accordance with the terms of this Section 3.09. The Issuers, the depositary for the Asset Sale Offer or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuers for purchase (or, if such Notes are then in global form, it will make such payment thereon through the facilities of DTC), and the Issuers will promptly execute a new Note, and, upon receipt of an Authentication Order in accordance with Section 2.02, the Trustee, upon the written request of the Issuers, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers will publicly announce the results of the Asset Sale Offer on the Purchase Date.

Section 4.01 Payment of Notes.

The Issuers will pay or cause to be paid the principal of, premium, if any, on, and interest, if any, on, the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest, if any, will be considered paid on the date due if the Paying Agent, if other than the Partnership or a Subsidiary of the Partnership, holds as of 11:00 a.m. Eastern Time on the due date money deposited by the Issuers in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due.

The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is equal to the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful.

65

The Issuers may at any time, for the purpose of obtaining satisfaction and discharge with respect to the Notes or for any other purpose, pay, or direct any Paying Agent to pay, to the Trustee all sums held in trust by the Issuers or such Paying Agent, such sums to be held by the Trustee upon the same terms as those upon which such sums were held by the Issuers or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Subject to any applicable escheat, or abandoned or unclaimed property law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Issuers on their request, or (if then held by the Partnership) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, shall thereupon cease.

Section 4.02 Maintenance of Office or Agency.

The Issuers will maintain, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee) where Notes may be surrendered for registration of transfer or for exchange. If Definitive Notes are issued and outstanding, such office must be in the contiguous United States. The Issuers initially designate the Corporate Trust Office of the Trustee for such purposes. The Issuers will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuers fail to maintain any such required office or agency or fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made or served at the Corporate Trust Office of the Trustee, provided, that, no office of the Trustee shall be an office or agency of the Issuers for the purposes of service of legal process on the Issuers or any Guarantor.

The Issuers may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Issuers of their obligation to maintain an office or agency in the contiguous United States for such purposes if required. The Issuers will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

With respect to any Global Notes, the Corporate Trust Office of the Trustee shall be the office or agency where such Global Notes may be presented or surrendered for payment or for registration of transfer or exchange, or where successor Notes may be delivered in exchange therefor; provided, however, that any such presentation, surrender or delivery effected pursuant to the Applicable Procedures of the Depositary shall be deemed to have been effected at such office or agency in accordance with the provisions of this Indenture.

Section 4.03 Reports.

(a) So long as any Notes are outstanding, the Partnership will furnish to the Holders of the Notes or the Trustee or post to the website referred to below, within the time periods specified in the SEC’s rules and regulations after giving effect to any extension under Rule 12b-25 under the Exchange Act or otherwise:

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

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

The availability of the foregoing information or reports on the SEC’s website will be deemed to satisfy the foregoing delivery requirements, provided, however, that the Trustee shall have no obligation whatsoever to determine if the Partnership has made such information or reports so available.

(b) Notwithstanding the foregoing, the financial statements, information and other documents required to be provided in Section 4.03(a) may be those of (i) the Partnership or (ii) any direct or indirect parent of the Parent; provided that in the case of clause (ii), if and so long as such parent has Independent Assets or Operations, the same is accompanied by consolidating information (which need not be audited) that explains in reasonable detail the differences between the information relating to such, on the one hand, and the information relating to the Parent and its Restricted Subsidiaries on a stand-alone basis, on the other hand.

(c) If the Partnership has designated any of its Subsidiaries as an Unrestricted Subsidiary and if any such Unrestricted Subsidiary or group of Unrestricted Subsidiaries, if taken together as one Subsidiary, would constitute a Significant Subsidiary of the Parent, then the annual and quarterly information required by clause (1) in Section 4.03(a) shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, of the financial condition and results of operations of the Parent and its Restricted Subsidiaries separate from the financial condition and results of operations of such Unrestricted Subsidiaries.

(d) Any and all Defaults or Events of Default arising from a failure to furnish in a timely manner any information required by this Section 4.03 shall be deemed cured (and the Partnership shall be deemed to be in compliance with this covenant) upon furnishing such information as contemplated by this covenant (but without regard to the date on which such information or report is so furnished); provided that such cure shall not otherwise affect the rights of the Holders in Section 6.01 if the principal of, premium, if any, on, and interest, if any, on, the Notes have been accelerated in accordance with the terms of this Indenture and such acceleration has not been rescinded or cancelled prior to such cure.

(e) So long as any Notes are outstanding, the Partnership will also maintain a website to which noteholders, prospective investors, broker-dealers and securities analysts are given access (which may be password protected) and to which all of the reports required by this Section 4.03 are posted, unless they are otherwise publicly filed with the SEC, and the posting of such reports to such website shall satisfy the above reporting requirements.

67

(f) The Partnership shall furnish to the Holders, prospective investors, broker-dealers and securities analysts, upon their request, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act.

(g) Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Partnership’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Trustee shall have no duty to monitor or confirm, on a continuing basis or otherwise, the Partnership’s or any other Person’s compliance with any of the covenants under this Indenture, to determine whether such reports, information or documents are filed with the SEC or made publicly available on a website, to examine such reports, information, documents and other reports to ensure compliance with the provisions of this Indenture, to ascertain the correctness or otherwise of the information or the statements contained therein or to participate in or monitor any conference calls. Notwithstanding the foregoing, the Trustee shall have no duty to search for or obtain any electronic or other filings that the Issuers make with the Commission, regardless of whether such filings are periodic, supplemental or otherwise.

Section 4.04 Compliance Certificate.

(a) The Partnership shall deliver to the Trustee, within 90 days after the end of each calendar year ending after the date of this Indenture, an Officers’ Certificate stating that a review of the activities of the Partnership and its Subsidiaries during the preceding calendar year has been made under the supervision of the signing Officers with a view to determining whether the Issuers have kept, observed, performed and fulfilled their obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Issuers have kept, observed, performed and fulfilled each and every covenant contained in this Indenture and are not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuers are taking or propose to take with respect thereto).

(b) So long as any of the Notes are outstanding, the Partnership will deliver to the Trustee, forthwith upon any Officer of the Partnership becoming aware of any Default or Event of Default, a written statement specifying such Default or Event of Default and what action the Issuers are taking or propose to take with respect thereto.

Section 4.05 Taxes.

The Issuers will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

68

Section 4.06 Stay, Extension and Usury Laws.

The Issuers and each of the Guarantors covenant (to the extent that they may lawfully do so) that they will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuers and each of the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenant that they will not, by resort to any such law, 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 has been enacted.

Section 4.07 Restricted Payments.

(a) The Partnership will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution on account of the Partnership’s or any of its Restricted Subsidiaries’ Equity Interests (including any payment in connection with any merger or consolidation involving the Partnership or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Partnership’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Partnership and other than dividends or distributions payable to the Partnership or a Restricted Subsidiary of the Partnership);

For purposes of determining compliance with the foregoing covenant, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in Section 4.07(b)(1) through (13), or is permitted pursuant to Section 4.07(a), the Partnership will be permitted to classify (or later classify or reclassify in whole or in part in its sole discretion) such Restricted Payment or other such transaction (or portion thereof) on the date made or later reclassify such Restricted Payment or other such transaction (or portion thereof) in any manner that complies with this Section 4.07. If any Person in which an Investment is made, which Investment constitutes a Restricted Payment when made, thereafter becomes a Restricted Subsidiary in accordance with this Indenture, all such Investments previously made in such Person

73

shall be Permitted Investments under clause (3) of the definition thereof, and for the avoidance of doubt, all such Investments shall no longer be counted as Restricted Payments for purposes of calculating the aggregate amount of Restricted Payments pursuant to Section 4.07(a)(4)(C), in each case, to the extent such Investments would otherwise be so counted.

Section 4.08 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

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

(1) pay dividends or make any other distributions on its Capital Stock to the Partnership or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any Indebtedness owed to the Partnership or any of its Restricted Subsidiaries; provided that the priority that any series of Preferred Stock of a Restricted Subsidiary has in receiving dividends, distributions or liquidating distributions before dividends, distributions or liquidating distributions are paid in respect of common stock of such Restricted Subsidiary shall not constitute a restriction on the ability to make dividends or distributions on Capital Stock for purposes of this Section 4.08;

(2) make loans or advances to the Partnership or any of its Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Partnership or any of its Restricted Subsidiaries to other Indebtedness incurred by the Partnership or any of its Restricted Subsidiaries shall not be deemed a restriction on the ability to make loans or advances); or

(3) sell, lease or transfer any of its properties or assets to the Partnership or any of its Restricted Subsidiaries.

(b) The restrictions in Section 4.08(a) hereof will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements governing Existing Indebtedness as in effect on the date of this Indenture and the Credit Agreement as in effect on the Issue Date and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the encumbrances or restrictions contained in the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not in the good faith judgment of an Officer of the Partnership materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of this Indenture;

(2) this Indenture, the Notes and the Note Guarantees;

74

(3) agreements governing other Indebtedness permitted to be incurred under the provisions of Section 4.09 hereof and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the encumbrances or restrictions contained therein are in the reasonable good faith judgment of an Officer of the Partnership, either (a) not materially more restrictive, taken as a whole, than those contained in this Indenture, the Notes and the Note Guarantees with respect to the Notes or the Credit Agreement as in effect on the date of this Indenture or (b) not reasonably likely to have a material adverse effect on the ability of the Partnership to make required payments on the Notes;

(4) applicable law, rule, regulation or order;

(5) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Partnership or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings thereof; provided, that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good faith judgment of an Officer of the Partnership, no more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided further, that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(6) customary non-assignment provisions in Hydrocarbon purchase and sale or exchange agreements or similar operational agreements or in licenses, easements or leases, in each case, entered into in the ordinary course of business;

(8) any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending its sale or other disposition;

(9) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are, in the reasonable good faith judgment of an Officer of the Partnership, not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(10) Liens permitted to be incurred under the provisions of Section 4.12 that limit the right of the debtor to dispose of the assets subject to such Liens;

(11) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment) entered into with the approval of the Partnership’s Board of Directors, which limitation is applicable only to the assets that are the subject of such agreements;

Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock.

(a) The Partnership will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Partnership will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any Preferred Stock; provided, however, that the Issuers may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and any Restricted Subsidiary may incur Indebtedness (including Acquired Debt) or issue Preferred Stock, if the Fixed Charge Coverage Ratio for the Partnership’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or such Preferred Stock is issued, as the case may be, would have been at least 2.00 to 1.00, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the Preferred Stock had been issued, as the case may be, at the beginning of such four-quarter period.

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

(1) the incurrence by the Partnership and the Restricted Subsidiaries, of Indebtedness and letters of credit under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Partnership and its Restricted Subsidiaries thereunder) not to exceed the greatest of (i) $850.0 million, (ii) the Borrowing Base in effect under the Credit Agreement at such time, and (iii) 32.5% of the Partnership’s Adjusted Consolidated Net Tangible Assets determined on the date of such incurrence;

(2) the incurrence by the Partnership and its Restricted Subsidiaries of the Existing Indebtedness;

(3) the incurrence by the Issuers and the Guarantors of Indebtedness represented by the Notes to be issued on the date of this Indenture and the related Note Guarantees;

(4) the incurrence by the Partnership or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) of the Partnership or any of its Restricted Subsidiaries or any Disqualified Stock of the Partnership, in each case that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (2), (3), (4), (13) or (15) of this Section 4.09(b);

77

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

(A) if the Partnership or any Guarantor is the obligor on such Indebtedness and the payee is not the Partnership or a Guarantor, such Indebtedness (excluding any Indebtedness in respect of accounts payable incurred in connection with goods and services rendered in the ordinary course of business or consistent with past practice (and not in connection with the borrowing of money)) must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Partnership, or the Note Guarantee, in the case of a Guarantor; and

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Partnership or a Restricted Subsidiary of the Partnership and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Partnership or a Restricted Subsidiary of the Partnership, will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Partnership or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (5);

(6) the issuance by any of the Partnership’s Restricted Subsidiaries to the Partnership or to any of its Restricted Subsidiaries of any Preferred Stock; provided, however, that:

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

(B) any sale or other transfer of any such Preferred Stock to a Person that is not either the Partnership or a Restricted Subsidiary of the Partnership, will be deemed, in each case, to constitute an issuance of such Preferred Stock by such Restricted Subsidiary that was not permitted by this clause (6);

(7) the incurrence by the Partnership or any of its Restricted Subsidiaries of Hedging Obligations;

(8) the Guarantee by the Partnership or any of its Restricted Subsidiaries of Indebtedness of the Partnership or a Restricted Subsidiary of the Partnership to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Guarantee must be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed;

(9) the incurrence by the Partnership or any of its Restricted Subsidiaries of Indebtedness in respect of self-insurance obligations or bid, plugging and abandonment, appeal, reimbursement, performance, surety and similar bonds and completion guarantees provided by the Partnership or a Restricted Subsidiary in the ordinary course of business or as required by requirements of law or governmental authorities and any Guarantees or letters of credit functioning as or supporting any of the foregoing bonds or obligations and workers’ compensation claims in the ordinary course of business or as required by requirements of law or governmental authorities;

78

(10) the incurrence by the Partnership or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within ten Business Days;

(11) the incurrence by the Partnership or any of its Restricted Subsidiaries of in-kind obligations relating to net oil or natural gas balancing positions arising in the ordinary course of business;

(12) any obligation arising from agreements of the Partnership or any Restricted Subsidiary of the Partnership providing for indemnification, adjustment of purchase price, earn outs, or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of any business, assets or Capital Stock of a Restricted Subsidiary in a transaction permitted by this Indenture; provided that such obligation is not reflected as a liability on the face of the balance sheet of the Partnership or any Restricted Subsidiary;

(13) any Permitted Acquisition Indebtedness;

(14) the incurrence by the Partnership or any of its Restricted Subsidiaries of Indebtedness in the ordinary course of business consisting of obligations owed to insurance providers or the financing of insurance premiums;

(15) the incurrence by the Partnership or any of its Restricted Subsidiaries of additional Indebtedness or the issuance by the Partnership of any Disqualified Stock in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred or Disqualified Stock issued pursuant to this clause (15), not to exceed the greater of (i) $125.0 million and (ii) 6.0% of the Partnership’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence or issuance; and

(16) customer deposits and advance payments received in the ordinary course of business or consistent with industry practice from customers for goods and services purchased in the ordinary course of business or consistent with industry practice.

For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (16) above, or is entitled to be incurred pursuant to Section 4.09(a), the Partnership will be permitted to divide, classify and reclassify such item of Indebtedness on the date of its incurrence, or later redivide or reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under the Credit Agreement outstanding on or prior to the Issue Date will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt.

The accrual of interest or Preferred Stock or Disqualified Stock dividends or distributions, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock or Disqualified Stock as Indebtedness due to a change in accounting principles,

79

and the payment of dividends or distributions on Preferred Stock or Disqualified Stock in the form of additional securities of the same class of Preferred Stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this Section 4.09; provided that the amount thereof shall be included in Fixed Charges of the Partnership as accrued to the extent required by the definition of such term.

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

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

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

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

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

(2) the amount of the Indebtedness of the other Person.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness or issuance of Disqualified Stock or Preferred Stock, the U.S. dollar-equivalent principal amount of Indebtedness, liquidation preference of Disqualified Stock or amount of Preferred Stock denominated in a foreign currency will be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness, Disqualified Stock or Preferred Stock was incurred or issued (or, in the case of revolving credit debt, the date such Indebtedness was first committed or first incurred (whichever yields the lower U.S. dollar equivalent)); provided that if such Indebtedness is incurred or Disqualified Stock or Preferred Stock is issued to refinance other Indebtedness, Disqualified Stock or Preferred Stock, as applicable, 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 will be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness, Disqualified Stock or Preferred Stock does not exceed (1) the principal amount of such Indebtedness, the liquidation preference of such Disqualified Stock or the amount of such Preferred Stock, as applicable, being refinanced, extended, replaced, refunded, renewed or defeased, plus (2) any accrued and unpaid interest on the Indebtedness, any accrued and unpaid dividends on the Preferred Stock and any accrued and unpaid dividends on the Disqualified Stock being so refinanced, extended, replaced, refunded, renewed or defeased, plus (3) the amount of any tender premium or penalty or premium required to be paid under the terms of the instrument or documents governing such refinanced Indebtedness, Preferred Stock or Disqualified Stock and any defeasance costs and any fees and expenses (including original issue discount, upfront fees or similar fees) incurred in connection with the issuance of such new Indebtedness, Preferred Stock or Disqualified Stock or the extension, replacement, refunding, refinancing, renewal or defeasance of such refinanced Indebtedness, Preferred Stock or Disqualified Stock.

80

If any Indebtedness is incurred, or Disqualified Stock or Preferred Stock is issued, in reliance on a basket measured by reference to a percentage of Adjusted Consolidated Net Tangible Assets, and any refinancing thereof would cause the percentage of Adjusted Consolidated Net Tangible Assets to be exceeded if calculated based on the Adjusted Consolidated Net Tangible Assets on the date of such refinancing, such percentage of Adjusted Consolidated Net Tangible Assets will not be deemed to be exceeded to the extent the principal amount of such newly incurred Indebtedness, the liquidation preference of such newly issued Disqualified Stock or the amount of such newly issued Preferred Stock does not exceed the sum of (i) the principal amount of such Indebtedness, the liquidation preference of such Disqualified Stock or the amount of such Preferred Stock being refinanced, extended, replaced, refunded, renewed or defeased, (ii) any accrued and unpaid interest on the Indebtedness, any accrued and unpaid dividends on the Preferred Stock and any accrued and unpaid dividends on the Disqualified Stock being so refinanced, extended, replaced, refunded, renewed or defeased and (iii) the amount of any tender premium or penalty or premium required to be paid under the terms of the instrument or documents governing such refinanced Indebtedness, Preferred Stock or Disqualified Stock and any defeasance costs and any fees and expenses (including original issue discount, upfront fees or similar fees) incurred in connection with the issuance of such new Indebtedness, Preferred Stock or Disqualified Stock or the extension, replacement, refunding, refinancing, renewal or defeasance of such refinanced Indebtedness, Preferred Stock or Disqualified Stock.

Section 4.10 Asset Sales.

The Partnership will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(a) the Partnership (or a Restricted Subsidiary, as the case may be) receives consideration (including by way of relief from, or by any Person assuming responsibility for, any liability, contingent or otherwise, in connection with such Asset Sale) at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(b) at least 75% of the aggregate consideration received in the Asset Sale by the Partnership or a Restricted Subsidiary and all other Asset Sales consummated since the Issue Date (on a cumulative basis) is in the form of cash or Cash Equivalents or any combination thereof. For purposes of this provision, each of the following will be deemed to be cash:

(1) any liabilities (as shown on the Partnership’s or any Restricted Subsidiary’s most recent balance sheet or in the notes thereto or, if incurred or accrued subsequent to the date of such balance sheet, such liabilities that would have been reflected on the Partnership’s or a Restricted Subsidiary’s consolidated balance sheet or in the notes thereto if such incurrence or accrual had taken place on or prior to the date of such balance sheet, as determined in good faith by the Partnership) of the Partnership or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are canceled, terminated or assumed by the transferee of any such assets pursuant to a novation, indemnity or other agreement that releases the Partnership or such Restricted Subsidiary from or indemnifies the Partnership or such Restricted Subsidiary against further liability;

81

(2) with respect to any Asset Sale of oil and natural gas properties by the Partnership or any Restricted Subsidiary where the Partnership or such Restricted Subsidiary retains an interest in such property, the costs and expenses of the Partnership or such Restricted Subsidiary related to the exploration, development, completion or production of such properties and activities related thereto which the transferee (or its Affiliate) agrees to pay;

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

(4) any Capital Stock or assets of the kind referred to in clause (2) or (4) of Section 4.10(c); and

(5) any Designated Non-cash Consideration received by the Partnership or such Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (5), not to exceed an amount equal to 5.0% of the Partnership’s Adjusted Consolidated Net Tangible Assets (determined at the time of receipt of such Designated Non-cash Consideration), with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

(c) Within 365 days after the receipt of any Net Proceeds from an Asset Sale (as may be extended pursuant to the immediately succeeding paragraph), the Partnership (or any Restricted Subsidiary) may apply such Net Proceeds at its option to any combination of the following:

(1) to repay, repurchase or redeem any Indebtedness of the Partnership or a Restricted Subsidiary of the Partnership, other than (i) Indebtedness of the Partnership or a Guarantor that is subordinated to the Notes or the Note Guarantees, or (ii) Indebtedness owed to an Affiliate of the Partnership;

(2) to acquire all or substantially all of the assets, or any Capital Stock, of one or more other Persons primarily engaged in the Oil and Gas Business, if, after giving effect to any such acquisition of Capital Stock, such Person becomes a Restricted Subsidiary of the Partnership;

(3) to make capital expenditures in respect of the Partnership’s or any Restricted Subsidiaries’ Oil and Gas Business; or

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in the Oil and Gas Business.

The requirement of clause (2), (3) or (4) of this Section 4.10(c) shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein is entered into by the Partnership or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Partnership within the time period specified in the preceding paragraph and such Net Proceeds are subsequently applied in accordance with such contract within 180 days following the date such agreement is entered into.

82

Pending the final application of any Net Proceeds, the Partnership (or any Restricted Subsidiary) may invest the Net Proceeds in any manner that is not prohibited by this Indenture.

Any Net Proceeds from Asset Sales that are not applied or invested as provided above in this Section 4.10(c) will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $35.0 million, within five days thereof, the Issuers will make an offer (an “Asset Sale Offer”) to all Holders of the Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Section 4.10 with respect to offers to purchase, prepay or redeem such Indebtedness with the proceeds of sales of assets to purchase, prepay or redeem, on a pro rata basis (based on the principal amount of Notes and pari passu Indebtedness or, in the case of pari passu Indebtedness issued with significant original issue discount, based on the accreted value thereof tendered), the maximum principal amount of Notes and such other pari passu Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount of the Notes and other pari passu Indebtedness to be purchased (or the lesser amount required under the agreements governing such other pari passu Indebtedness), plus accrued and unpaid interest, if any, to, but excluding, the date of purchase, prepayment or redemption, subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Partnership or any Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds allocated to the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (except that any Notes represented by a Note in global form will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law), based on the amounts tendered (with such adjustments as may be deemed appropriate by the Partnership so that only Notes in minimum denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. The Issuers may satisfy the foregoing obligations with respect to Excess Proceeds by making an Asset Sale Offer prior to the expiration of the application period referred to in this Section 4.10(c) or with respect to Excess Proceeds of $35.0 million or less.

The Partnership will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with Section 3.09 or this Section 4.10, the Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 or this Section 4.10 by virtue of such compliance.

83

Section 4.11 Transactions with Affiliates.

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

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

(2) the Partnership delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration more than $25.0 million, an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, a Board Resolution of the Partnership set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Partnership, if any.

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

(1) any employment or consulting agreement, employee benefit plan, officer or director indemnification, compensation or severance agreement or any similar arrangement entered into by the Partnership or any of its Restricted Subsidiaries or any direct or indirect parent (including the Parent) of the Partnership in the ordinary course of business and payments pursuant thereto;

(2) transactions between or among the Partnership and/or its Restricted Subsidiaries or Parent (or an entity that becomes a Restricted Subsidiary as a result of such transaction);

(5) any issuance of Equity Interests (other than Disqualified Stock) of the Partnership to Affiliates of the Partnership;

(6) Permitted Investments or Restricted Payments that do not violate the provisions of Section 4.07 hereof;

(7) transactions effected in accordance with the terms of the agreements of the Partnership or any Restricted Subsidiary that are in effect on the date of this Indenture, and any amendment or replacement of any of such agreements so long as such amendment or replacement agreement is not materially less advantageous to the Partnership, taken as a whole, than the agreement so amended or replaced;

(8) loans or advances to or reimbursements of expenses incurred by employees for moving, entertainment and travel expenses and similar expenditures in the ordinary course of business;

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

(10) in the case of contracts for exploring for, producing, marketing, storing, gathering, transporting or otherwise handling Hydrocarbons, or activities or services reasonably related or ancillary thereto, or other operational contracts, any such contracts entered into in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are fair to the Partnership and its Restricted Subsidiaries, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party, in either case in the reasonable determination of the Board of Directors of the Partnership or the senior management thereof;

(11) payments to Affiliates on or with respect to debt securities or other Indebtedness of the Partnership or any Subsidiary on a similar basis as payments are made or offered to holders of such debt securities or Indebtedness held by Persons other than Affiliates;

(12) any transaction in which the Partnership or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Partnership or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of Section 4.11(a)(1);

85

(13) transactions with customers, clients, suppliers, contractors, joint venture partners or purchasers or sellers of goods or services (other than an Unrestricted Subsidiary), or transactions otherwise relating to the purchase or sale of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are, in the aggregate (taking into account all the costs and benefits associated with such transactions), not materially less favorable to the Partnership or its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Partnership or such Restricted Subsidiary with an unrelated Person, as determined in good faith by the Partnership, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

(14) any lease (other than any lease of Oil and Gas Properties) entered into between the Partnership or any Restricted Subsidiary, as lessee, and any Affiliate of the Partnership, as lessor, and transactions pursuant to that lease which lease is approved by the Board of Directors or senior management of the Partnership in good faith;

(15) intellectual property licenses in the ordinary course of business or consistent with industry practice;

(17) (A) pledges and other transfers of Equity Interests in Unrestricted Subsidiaries and (B) any transactions with an Affiliate in which the consideration paid consists solely of Equity Interests of the Partnership.

Section 4.12 Liens.

The Partnership will not and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien (an “Initial Lien”) of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired, unless the Notes or any Note Guarantee of such Restricted Subsidiary, as applicable, are secured on an equal and ratable basis with the Indebtedness so secured until such time as such Indebtedness is no longer secured by a Lien. Any Lien created for the benefit of the Holders of the Notes pursuant to this paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien. In the event that an Initial Lien is or becomes a Permitted Lien, the Partnership may, at its option and without the consent of any Holder, elect to release and discharge any Lien created for the benefit of the Holders pursuant to this Section 4.12 in respect of such Initial Lien.

86

Section 4.13 Permitted Business Activities of Finance Corp.

Finance Corp. will not hold any material assets, become liable for any material obligations or engage in any significant business activities; provided, that Finance Corp. may be a co-obligor or guarantor with respect to Indebtedness if the Partnership is an obligor on such Indebtedness and the net proceeds of such Indebtedness are received by the Partnership, Finance Corp. or one or more Restricted Subsidiaries. At any time after the Partnership is a corporation, Finance Corp. may consolidate or merge with or into the Partnership or any Restricted Subsidiary. Otherwise, Finance Corp. may not merge or consolidate with or into another Person unless the Person surviving such merger or consolidation, if other than Finance Corp., is a corporation.

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

(b) the rights (charter and statutory), licenses and franchises of the Partnership and its Restricted Subsidiaries;

provided, however, that the Partnership shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Partnership shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Partnership and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, the Issuers will make an offer (a “Change of Control Offer”) to each Holder of Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment Date”), subject to the rights of Holders of such Notes on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 30 days following any Change of Control, the Issuers will send or deliver (or cause to be transferred by book entry) a notice to each Holder of Notes, with a copy to the Trustee, describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes validly tendered prior to the expiration of the Change of Control Offer will be accepted for payment;

87

(2) the purchase price and the expiration date of the Change of Control Offer, which shall be no earlier than 30 days and no later than 60 days from the date such notice is sent;

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

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

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

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

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

The Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, the Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

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

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

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

88

The Paying Agent, at the Issuers’ expense, will promptly deliver (but in any case not later than five days after the Change of Control Payment Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, it will make such payment through the facilities of DTC), and the Issuers will promptly execute a new Note, and, upon receipt of an Authentication Order in accordance with Section 2.02, the Trustee, upon the written request of the Issuers, will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Issuers will announce to the Holders of the Notes the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) Notwithstanding anything to the contrary in this Section 4.15, the Issuers will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Section 4.15 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (2) notice of redemption of all outstanding Notes has been given pursuant to Section 3.03 hereof, unless and until there is a default in payment of the applicable redemption price, or (3) in connection with or in contemplation of any Change of Control, the Issuers have made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer.

(d) Notwithstanding anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer or Alternate Offer is made. The settlement date of any such Change of Control Offer or Alternate Offer made in advance of a Change of Control may be changed to conform to the actual closing date of such Change of Control; provided that such settlement date is not earlier than 30 days nor later than 60 days from the date the Change of Control Offer notice is sent as described in Section 4.15(a).

Section 4.16 Additional Note Guarantees.

(a) If any Restricted Subsidiary, other than Finance Corp., that is not a Guarantor (including any acquired or newly created Restricted Subsidiary) Guarantees any Indebtedness of the Partnership or a Guarantor under a Credit Facility, then such Restricted Subsidiary will become a Guarantor of the Notes by executing a supplemental indenture in substantially the form of Exhibit D hereto within 30 days after the date that Restricted Subsidiary Guaranteed such Indebtedness.

(b) If at any time the Parent owns material assets other than direct or indirect interests in the Partnership or its general partner or its Subsidiaries, cash and cash equivalents or assets that are to be contributed or transferred to the Partnership or its Subsidiaries within 30 days of the acquisition thereof, Parent will execute a supplemental indenture in substantially the form of Exhibit D hereto within 30 days after it owns such material assets, whereupon it will be deemed to be a “Guarantor” for purposes of this Indenture but will not otherwise be subject to any of the restrictive covenants in this Indenture. The Note Guarantee of Parent shall automatically be

89

released if at any time after Parent becomes a Guarantor it ceases to own any material assets other than direct or indirect interest in the Partnership, its general partner or its Subsidiaries and cash and cash equivalents. Any release pursuant to the preceding sentence shall be deemed to occur automatically, without further action by the Trustee or Holders of Notes, upon delivery by the Partnership of an Officers’ Certificate stating that the conditions to such release have been satisfied.

Section 4.17 Designation of Restricted and Unrestricted Subsidiaries.

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

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

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

Section 4.18 Covenant Suspension.

If at any time following the Issue Date (a) the Notes obtain at least two of any of the following three ratings: (i) Baa3 or better by Moody’s, (ii) BBB- or better by S&P and (iii) BBB- or better from Fitch (or, if any of such entities ceases to rate the Notes for reasons outside of the control of the Partnership, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act selected by the Partnership as a replacement agency) (an “Investment Grade Rating”) and (b)

90

no Default or Event of Default shall have occurred and be continuing under this Indenture, then upon delivery by the Partnership to the Trustee of an Officers’ Certificate certifying to such events, Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.17 and 5.01(a)(4) of this Indenture (the “Suspended Covenants”) will be suspended and the limitations in such covenants will cease to apply and no Default or Event of Default shall result from any failure to comply with any of the provisions of such Sections.

During any period that the Suspended Covenants have been suspended (the “Suspension Period”), the Partnership may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.17 or the definition of “Unrestricted Subsidiary.”

Notwithstanding the foregoing, if the Notes cease to have an Investment Grade Rating, the Suspended Covenants will be reinstituted as of and from the date of such occurrence, except that no Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture or the Notes with respect to the Suspended Covenants based on, and none of the Partnership or any of its Subsidiaries shall have any liability for, any actions taken or events occurring during the Suspension Period, regardless of whether such actions or events would have been permitted if the Suspended Covenants had remained in effect during such period (or after the reinstatement date based solely on contractual obligations or other events arising during the Suspension Period). For purposes of calculations under the reinstated Section 4.07, Restricted Payments will made during a Suspension Period will be disregarded. Furthermore, all Indebtedness incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period will be deemed to have been incurred or issued pursuant to clause (2) of the definition of “Permitted Debt.”

In addition, for purposes of Section 4.11, all agreements and arrangements entered into by the Partnership or any Restricted Subsidiary with an Affiliate of the Partnership during the Suspension Period will be deemed to have been entered into prior to the date of this Indenture, and for purposes of Section 4.08, all contracts entered into during the Suspension Period that contain any of the restrictions contemplated by such section will be deemed to have been existing on the date of this Indenture.

The Trustee shall not have any duty to (a) monitor the ratings of the Notes, (b) determine whether a Suspension Period has occurred or ended, (c) notify Holders of any of the foregoing or (d) determine the consequences thereof, but may provide a copy of such Officers’ Certificate to any Holder upon written request.

94

Section 6.02 Acceleration.

In the case of an Event of Default specified in clause (h) or (i) of Section 6.01 hereof, with respect to the Partnership, Finance Corp., any Restricted Subsidiary of the Partnership that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Partnership that, taken together, would constitute a Significant Subsidiary, the principal of, and accrued and unpaid interest, if any, on all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default with respect to the Notes occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes (with a copy to the Trustee) may declare the principal of, and accrued and unpaid interest, if any, on all outstanding Notes to be due and payable immediately. However, a Default under clauses (c), (d), (e), (f) or (g) of Section 6.01 will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes notify the Partnership of the Default and, with respect to clauses (d), (e) or (g) of Section 6.01, the Partnership does not cure such Default within the time specified in clauses (d), (e) or (g) of Section 6.01 after receipt of such notice; provided that a notice of Default may not be given with respect to any action taken, and reported publicly or to Holders, more than two years prior to such notice of Default.

Any notice of Default, notice of acceleration or instruction delivered to the Trustee to provide a notice of Default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any one or more Holders (each a “Directing Holder”) must be accompanied by a written representation from each such Holder delivered to the Partnership and the Trustee that such Holder is not (or, in the case such Holder is DTC or its nominee, that such Holder is being instructed solely by Beneficial Owners that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default (a “Default Direction”) shall be deemed a continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the Notes are accelerated. In addition, each Directing Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide the Partnership with such other information as the Partnership may reasonably request from time to time in order to verify the accuracy of such Noteholder’s Position Representation within five Business Days of request therefor (a “Verification Covenant”). The Trustee shall have no duty whatsoever to provide this information to the Partnership or to obtain this information for the Partnership. In any case in which the Holder is DTC or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the Beneficial Owner of the Notes in lieu of DTC or its nominee and DTC shall be entitled to conclusively rely on such Position Representation and Verification Covenant in delivering its direction to the Trustee.

If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Partnership determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officers’ Certificate stating that the Partnership has initiated litigation in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Default, Event of Default or acceleration (or notice thereof) that resulted from the applicable Noteholder Direction, the cure

95

period with respect to such Default shall be automatically stayed and the cure period with respect to such Default or Event of Default shall be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Partnership provides to the Trustee an Officers’ Certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to any Default or Event of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation shall result in such Directing Holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such Directing Holder, the percentage of Notes held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Default or Event of Default shall be deemed never to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default; provided, however, this shall not invalidate any indemnity and/or security provided by the Directing Holders to the Trustee, which obligations shall continue to survive. If the Directing Holder has satisfied its Verification Covenant, then the Trustee shall be permitted to act in accordance with such Noteholder Direction. Notwithstanding the above, if such Directing Holder’s participation is not required to achieve the requisite level of consent of holders required under this Indenture to give such Noteholder Direction, the Trustee shall be permitted to act in accordance with such Noteholder Direction notwithstanding any action taken or to be taken by the Partnership (as described above).

Notwithstanding anything in the preceding two paragraphs to the contrary, any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default specified in clauses (a), (b), (h) or (i) of Section 6.01 hereof, with respect to the Partnership, any Restricted Subsidiary of the Partnership that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Partnership that, taken together, would constitute a Significant Subsidiary, shall not require compliance with the foregoing paragraphs.

For the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with this Indenture, shall have no duty to inquire as to or investigate the accuracy or authenticity of any Position Representation or determine whether it complies with the provisions of this Indenture, enforce compliance with any Verification Covenant, to monitor, investigate, verify or otherwise determine if a Holder has a Net Short Position, inquire if the Partnership will seek action to determine if a Directing Holder has breached its Position Representation or monitor any court proceedings undertaken in connection therewith, verify any statements in any Officers’ Certificate delivered to it, or otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise and shall have no liability for ceasing to take any action or staying any remedy, or otherwise failing to act in accordance with a Noteholder Direction. With their acquisition of the Notes, each Holder by its purchase of the Notes and subsequent purchaser of the Notes consents to the delivery of its Position Representation by the Trustee to the Partnership in accordance with this Section 6.02. The Trustee shall have no liability to the Partnership, any holder or any Person in acting in good faith on a Noteholder Direction or for determining whether any holder has delivered a Position Representation. The

96

Partnership and each Holder by its purchase of the Notes and subsequent purchaser of the Notes waives any and all claims, in law and/or in equity, against the Trustee and agrees not to commence any legal proceeding against the Trustee in respect of, and agrees that the Trustee will not be liable for any action that the Trustee takes in accordance with this Section 6.02, or arising out of or in connection with following instructions or taking actions in accordance with a Noteholder Direction. Each Holder by its purchase of the Notes and subsequent purchaser of the Notes acknowledges and agrees that neither the Trustee nor any agent thereof shall be liable to any person for acting or refraining to act in accordance with (i) this Section 6.02, (ii) any Noteholder Direction, (iii) any Officers’ Certificate delivered in connection therewith, or (iv) its duties under this Indenture as Trustee as determined by the Trustee as a result of this Section 6.02.

In connection with the requisite percentages required under this Section 6.02, the Trustee shall treat all outstanding Notes equally irrespective of any Position Representation in determining whether the requisite percentage has been obtained with respect to the initial delivery of the Noteholder Direction. The Partnership hereby confirms that any and all other actions that the Trustee takes or omits to take under this Section 6.02 and all fees, costs expenses of the Trustee and its agents and counsel arising hereunder and in connection herewith shall be covered by the Partnership’s indemnifications under Section 7.07.

Section 6.03 Other Remedies.

If an Event of Default occurs and is continuing, and is known to the Trustee (as provided in Section 7.02(g)), the Trustee may pursue any available remedy to collect the payment of principal of, premium, if any, on, and interest, if any, on, the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default, other than to the extent set forth in Section 6.02. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium, if any, on, and interest, if any, on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

97

Section 6.05 Control by Majority.

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes (it being understood that the Trustee does not have any duty to determine whether any action is prejudicial to any Holder) or that may involve the Trustee in personal liability. Prior to taking any such action hereunder, the Trustee shall be entitled to indemnification and/or security satisfactory to it against all fees, losses, liabilities and expenses (including attorneys’ fees and expenses) that may be caused by taking or not taking such action.

Section 6.06 Limitation on Suits.

Except to enforce the right to receive payment of principal, premium, if any, or interest, if any, when due on the Notes, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

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

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

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

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

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

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such uses are unduly prejudicial to such Holders).

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, premium, if any, on, and interest, if any, on, the Note, on or after the respective due dates expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be amended or waived in a manner adverse to such Holder without the consent of such Holder.

98

Section 6.08 Collection Suit by Trustee.

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

Section 6.09 Trustee May File Proofs of Claim.

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

Section 6.11 Undertaking for Costs.

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

Section 6.12 Restoration of Rights and Remedies.

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

ARTICLE 7

TRUSTEE

Section 7.01 Duties of Trustee.

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

(b) Except during the continuance of an Event of Default:

The Trustee shall be under no duty to make any investigation as to any statement contained in any such instance, but may accept the same as conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions. However, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be delivered to the Trustee, the Trustee will examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(1) this paragraph does not limit the effect of paragraph (b) of this Section 7.01;

(2) the Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer or for any action taken or omitted to be taken by it in good faith and reasonably believed by it to be within the power conferred upon it by this Indenture, unless it is proved by a court of competent jurisdiction in a final non-appealable decision that the Trustee was grossly negligent in ascertaining the pertinent facts; and

The Trustee need not investigate any fact or matter stated in the document.

101

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

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

(f) The Trustee will 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 have offered to the Trustee indemnity and/or security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

(g) The Trustee shall not be deemed to have notice of a Default or an Event of Default other than an Event of Default under Section 6.01(a) and Section 6.01(b) unless written notice of such Default or Event of Default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes, the Issuers and this Indenture.

(i) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

102

(l) The permissive rights of the Trustee enumerated herein and in the other Note Documents shall not be construed as duties.

(m) Whenever in the administration of this Indenture or the Notes, the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder or thereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of gross negligence or willful misconduct on its part (as determined by a final nonappealable order of a court of competent jurisdiction), conclusively rely upon an Officers’ Certificate and/or an Opinion of Counsel.

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Partnership or any Affiliate of the Partnership with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA) after a Default has occurred and is continuing it must eliminate such conflict within 90 days or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.06 hereof.

Section 7.04 Trustee’s Disclaimer.

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Partnership’s use of the proceeds from the Notes or any money paid to the Partnership or upon the Partnership’s direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by the Notes. In accepting the trust hereby created, the Trustee acts solely as Trustee under this Indenture and not in its individual capacity and all Persons, including without limitation, the Holders of Notes and the Issuers, having any claim against the Trustee arising from this Indenture shall look only to the funds and accounts held by the Trustee hereunder for payment except as otherwise provided herein. The Trustee shall have no obligation to independently determine or verify if any event has occurred or notify the Holders of any event dependent upon the rating of the Notes, or if the rating on the Notes has been changed, suspended or withdrawn by any rating agency. The Trustee shall have no obligation to independently determine or verify if any Change of Control, Suspension Period, reinstatement date, or any other event has occurred or notify the Holders of any such event.

103

Section 7.05 Notice of Defaults.

If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee in accordance with the terms hereof, the Trustee will send electronically or mail to Holders of the Notes a notice of the Default or Event of Default within 90 days after any such Default or Event of Default is actually known to a Responsible Officer of the Trustee in accordance with the terms hereof. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, on, and interest, if any, on, any Note, the Trustee may (but is not obligated to) withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.06 Eligibility; Disqualification.

There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition.

Section 7.07 Compensation and Indemnity.

(a) The Issuers and the Guarantors, jointly and severally, will pay to the Trustee from time to time documented 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 will not be limited by any law on compensation of a trustee of an express trust. The Issuers and the Guarantors, jointly and severally, will reimburse the Trustee promptly upon request for all documented disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the documented compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b) The Issuers and the Guarantors, jointly and severally, will indemnify the Trustee and its directors, officers, employees and agents and any predecessor trustee against any and all losses, liabilities or expenses incurred by them (including taxes (other than taxes based upon the income of the Trustee) and documented attorneys’ and agents’ fees and expenses and court costs) arising out of or in connection with the acceptance or administration of the Trustee’s duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuers and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuers, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its rights, powers or duties hereunder (including actions taken or omitted to be taken pursuant to Section 6.02), except to the extent any such loss, liability or expense is attributable to its gross negligence or willful misconduct, as determined by a final nonappealable order of a court of competent jurisdiction. The Trustee will notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers will not relieve the Issuers or any of the Guarantors of their obligations hereunder. The Issuers or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Issuers will pay the documented fees and expenses of

104

such counsel. None of the Issuers or any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld. Any settlement which affects the Trustee may not be entered into without the written consent of the Trustee, unless the Trustee is given a full and unconditional release from liability with respect to the claims covered thereby and such settlement does not include a statement or admission of fault, culpability or failure to act by or on behalf of the Trustee.

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

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

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

Section 7.08 Replacement of Trustee.

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

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing not less than 30 days prior to the effective date of such removal. The Issuers may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.06 hereof;

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

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

(4) the Trustee becomes incapable of acting.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuers will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers.

105

(d) If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Issuers’ expense), the Issuers, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.06 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will deliver a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the successor Person without any further act will be the successor Trustee.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuers may at any time elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

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

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

106

(b) the Issuers’ obligations with respect to such Notes under Sections 2.03, 2.04, 2.06, 2.07, 2.10 and 4.02 hereof;

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

(d) this Article 8.

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

Section 8.03 Covenant Defeasance.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their respective obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof and clauses (3) and (4) of Section 5.01(a) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders of the Notes (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes to the extent permitted by GAAP). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(c), (d), (e), (f), (g) and (j) hereof will not constitute Events of Default.

(b) in the case of an election under Section 8.02 hereof, the Partnership must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

(1) the Partnership has received from, or there has been published by, the Internal Revenue Service a ruling; or

(2) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the beneficial owners of the Notes of such series for U.S. Federal income tax purposes of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(c) in the case of an election under Section 8.03 hereof, the Partnership must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the beneficial owners of the Notes of such series for U.S. Federal income tax purposes of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d) no Default or Event of Default with respect to the Notes has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

108

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

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

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

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

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

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

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

Section 8.06 Repayment to Issuers.

Subject to any applicable escheat, or abandoned or unclaimed property law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium, if any, on, and interest, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable

109

shall be paid to the Issuers on their request or (if then held by the Issuers) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, will thereupon cease.

Section 8.07 Reinstatement.

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

(d) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under this Indenture of any Holder of Notes, including to comply with requirements of the SEC or DTC in order to maintain the transferability of the Notes pursuant to Rule 144A or Regulation S;

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

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

(h) to secure the Notes or the Note Guarantees pursuant to the requirements of Section 4.12 hereof;

(i) to add any additional Guarantee of the Notes as provided in this Indenture or otherwise, or to evidence the release of any Guarantor from its Note Guarantee as provided in this Indenture;

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture (including Sections 3.09, 4.10, and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and any existing Default or Event of Default or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(b) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption or repurchase of the Notes (other than provisions under Sections 3.09, 4.10 or 4.15 or the minimum notice required with respect to any redemption of Notes pursuant to Article 3);

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

111

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

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

(f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of the Notes to receive payments of principal of, premium, if any, on, or interest, if any, on, the Notes (other than as permitted in clause (g) of this Section 9.02 below);

(g) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Section 3.09, 4.10 or 4.15);

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

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

For the avoidance of doubt, no amendment to, or deletion of any of the covenants in this Indenture or action taken in compliance with the covenants in effect at the time of such action, shall be deemed to impair or affect any rights of any Holder of Notes to receive payment of principal of, or premium, if any, or interest, if any, on, the Notes or to institute suit for the enforcement of payment on or with respect to such Holder’s Notes.

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

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

Section 9.03 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder unless it makes a change described in any of clauses (a) through (i) of the first paragraph of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to such amendment, supplement or waiver and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

112

Section 9.04 Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuers in exchange for all Notes may execute and the Trustee shall, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, authenticate new Notes that reflect the amendment, supplement or waiver.

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

Section 9.05 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the Trustee determines that the amendment or supplement does not adversely affect the rights, duties, liabilities, privileges, protections, benefits, indemnities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee shall receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such supplemental indenture is the legal, valid and binding obligation of the Issuers and Guarantors enforceable against them in accordance with its terms.

Section 9.06 Effect of Supplemental Indentures.

Upon the execution of any amended or supplemental indenture under this Article 9, this Indenture shall be modified in accordance therewith, and such amended or supplemental indenture shall form a part of this Indenture for all purposes and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby, unless such amended or supplemental indenture makes a change described in any of clauses (a) through (i) of the first paragraph of Section 9.02, in which case, such amended or supplemental indenture shall bind only each Holder of a Note who has consented to such amended or supplemental indenture and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

ARTICLE 10

NOTE GUARANTEES

Section 10.01 Guarantee.

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

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

113

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

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

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

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

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations Guaranteed hereby until payment in full of all obligations Guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations Guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations Guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

114

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor and, by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Note Guarantee.

The Note Guarantee of any Guarantor shall be evidenced solely by its execution and delivery of this Indenture (or, in the case of any Guarantor that is not party to this Indenture as of the date hereof, a supplemental indenture) and not by an endorsement on, or attachment to, any Note of any Note Guarantee or notation thereof. Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 shall be and remain in full force and effect notwithstanding any failure to endorse on any Note a notation of such Note Guarantee. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantees set forth in this Indenture on behalf of each of the Guarantors.

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

Except as otherwise provided in Section 10.05 hereof, no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Partnership or another Guarantor, unless:

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

(b) either:

(1) subject to Section 10.05 hereof, the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) unconditionally assumes all the obligations of that Guarantor under its Note Guarantee and this Indenture pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee; or

(2) such transaction or series of transactions does not violate Section 4.10 hereof.

115

In case of any such consolidation or merger and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee of the Guarantor and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. All the Note Guarantees relating to Notes issuable hereunder which theretofore shall not have been signed by the Partnership and delivered to the Trustee will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

Notwithstanding clauses (a) or (b) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Partnership or another Guarantor, or will prevent any sale or other disposition of the properties or assets of a Guarantor as an entirety or substantially as an entirety to the Partnership or another Guarantor.

Section 10.05 Releases.

Notwithstanding Section 10.04, the Note Guarantee of a Guarantor shall automatically be released:

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

(b) in connection with any sale, exchange, transfer or other disposition of Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Partnership or a Restricted Subsidiary of the Partnership, if the sale, exchange, transfer or other disposition does not violate Section 4.10 hereof and such Guarantor ceases to be a Restricted Subsidiary of the Partnership as a result of the sale, exchange, transfer or other disposition;

(c) upon designation of such Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture;

(d) at such time as such Guarantor does not Guarantee any Indebtedness of the Partnership or another Guarantor under a Credit Facility, other than the Notes;

(e) upon the liquidation or dissolution of such Guarantor in a transaction or series of transactions that does not violate the terms of this Indenture; or

(f) as described in Article 9 hereof.

In addition, the Note Guarantees of all Guarantors will be released upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 11 hereof.

116

Any release pursuant to the foregoing shall be deemed to occur automatically, without further action by the Trustee or Holders of Notes, upon delivery by the Partnership of an Officers’ Certificate stating that the conditions to such release have been satisfied. Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of, premium, if any, on, and interest, if any, on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

ARTICLE 11

SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

This Indenture will be satisfied and discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration of transfer or exchange of the Notes and as otherwise specified in this Article 11), and the Trustee, at the expense of the Issuers, shall execute proper instruments acknowledging such satisfaction and discharge of this Indenture, when:

(a) either:

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

(2) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the delivery of a notice of redemption or otherwise and either the Issuers or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient (in the opinion of an independent accounting or appraisal firm in the case of any deposit of Government Securities), without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and interest, if any, to the date of Stated Maturity or redemption (provided that if such redemption requires the payment of any Applicable Premium, (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited the Additional Premium Deficit in trust on the redemption date as necessary to pay such Applicable Premium as determined by such date; provided any Applicable Premium Deficit shall be set forth in an Officers’ Certificate delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit shall be applied toward such redemption; provided further that the Trustee shall have no liability whatsoever in the even that such Applicable Premium Deficit is not in fact paid after any satisfaction and discharge);

(b) the Issuers have paid or caused to be paid all other sums payable by the Issuers under this Indenture; and

117

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

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

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (2) of clause (a) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02 Application of Trust Money.

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

The Issuers and Guarantors, jointly and severally, will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 11.01 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

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

Notwithstanding the above, the Trustee shall pay to the Issuers from time to time upon its request any money or Government Securities held by the Trustee as provided in this Section 11.02 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect satisfaction and discharge under this Article 11.

118

Subject to any applicable escheat, or abandoned or unclaimed property law, any money or Government Securities deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Issuers on their request or (if then held by the Issuers) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, shall thereupon cease.

ARTICLE 12

MISCELLANEOUS

Section 12.01 Force Majeure.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, but not limited to, (i) any act or provision of any present or future law or regulation or governmental authority, (ii) any act of God, (iii) natural disaster, (iv) war, (v) terrorism, (vi) civil unrest, (vii) accidents, (viii) labor dispute, (ix) disease, (x) epidemic or pandemic, (xi) quarantine, (xii) national emergency, (xiii) loss or malfunction of utility or computer software or hardware, (xiv) communications system failure, (xv) malware or ransomware; (xvi) unavailability of the Federal Reserve Bank wire or telex system or other wire or other funds transfer systems, or (xvii) unavailability of any securities clearing system; it being understood that the Trustee shall use commercially reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

Any notice or communication by the Issuers, any Guarantor, the Parent or the Trustee to the others is duly given if in writing in the English language and delivered in Person or by first class mail (registered or certified, return receipt requested), electronic image scan, or transmission or overnight air courier guaranteeing next day delivery, to the others’ address:

All notices and communications (other than those sent to Holders) will be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt acknowledged, if transmitted by electronic image scan or transmission; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by the Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Notwithstanding anything to the contrary contained herein, as long as the Notes are in the form of a Global Note, notice to the Holders of such Notes may be made electronically in accordance with procedures of the Depositary.

Section 12.03 U.S.A. Patriot Act.

The parties hereto acknowledge that in accordance with Section 326 of the U.S.A.

Any certificate or opinion of an Officer with respect to any Person may be based, insofar as it relates to legal matters, upon a certificate or 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, or representation by, counsel may be based, insofar as it relates to factual matters, upon certificates of public officials or upon a certificate or opinion of, or representations by, an Officer or Officers with respect to any Person stating that the information with respect to such factual matters is in the possession of such Person (or, if such Person is a limited partnership, such Person’s general partner) unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

Section 12.08 Governing Law; Waiver of Jury Trial.

THE LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES. EACH OF THE PARTNERSHIP, FINANCE CORP., THE GUARANTORS, THE PARENT AND THE TRUSTEE HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE GUARANTEES AND FOR ANY COUNTERCLAIM THEREIN.

If any payment with respect to any principal of, premium, if any, on, or interest, if any, on any Note (including any payment to be made on any date fixed for redemption or purchase of any Note) is due on a day which is not a Business Day, then the payment need not be made on such date, but may be made on the next Business Day with the same force and effect as if made on such date, and no interest will accrue for the intervening period.

Section 12.15 Evidence of Action by Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given, made or taken by the Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing, and may be given, made or taken in connection with a purchase of, or tender offer or exchange offer for, outstanding Notes; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuers. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Issuers if made in the manner provided in this Section 12.15.

Without limiting the generality of this Section 12.15, unless otherwise provided in or pursuant to this Indenture, (i) a Holder, including a Depositary or its nominee that is a Holder of a Global Note, may give, make or take, by an agent or agents duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture to be given, made or taken by the Holders, and a Depositary or its nominee that is a Holder of a Global Note may duly appoint in writing as its agent or agents members of, or participants in, such Depositary holding interests in such Global Note in the records of such Depositary; and (ii) with respect to any Global Note the Depositary for which is DTC, any consent or other action given, made or taken by an “agent member” of DTC by electronic means in accordance with the Automated Tender Offer Procedures system or other customary procedures of, and pursuant to authorization by, DTC shall be deemed to constitute the “Act” of the Holder of such Global Note, and such Act shall be deemed to have been delivered to the Issuers and the Trustee upon the delivery by DTC of an “agent’s message” or other notice of such consent or other action having been so given, made or taken in accordance with the customary procedures of DTC.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such witness, notary or officer the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

124

(c) Notwithstanding anything to the contrary contained in this Section 12.15 or elsewhere in this Indenture, the principal amount and serial numbers of Notes held by any Holder, and the date of holding the same, shall be proved by the register of the Notes maintained by the Registrar as provided in Section 2.03.

(d) If the Issuers shall solicit from the Holders of the Notes any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuers may, at their option, fix in advance a record date for the determination of the Holders entitled to give, make or take such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Partnership shall have no obligation to do so. Such record date shall be the record date specified in or pursuant to such resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of the Holders generally in connection therewith or the date of the most recent list of the Holders forwarded to the Trustee prior to such solicitation pursuant to Section 2.05 and not later than the date such solicitation is completed. If such a record date is fixed, then notwithstanding the second sentence of Section 9.03, any instrument embodying and evidencing such request, demand, authorization, direction, notice, consent, waiver or other Act may be executed before or after such record date, but only the Holders of record at the close of business on such record date (whether or not such Persons were Holders before, or continue to be Holders after, such record date) shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of the then outstanding Notes have given, made or taken such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the then outstanding Notes shall be computed as of such record date; provided that no such Act by the Holders of record on any record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after such record date.

(e) Subject to Section 9.03, any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Issuers in reliance thereon, whether or not notation of such action is made upon such Note.

(f) Without limiting the foregoing, a Holder entitled hereunder to give, make or take any action hereunder with regard to any particular Note may do so itself with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

Section 12.16 Benefit of Indenture.

Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Registrar and their successors hereunder, and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 12.17 Language of Notices, Etc.

Any request, demand, authorization, direction, notice, consent, waiver or Act required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication.

Section 12.18 Calculations.

The Issuers will be responsible for making all calculations called for under this Indenture or the Notes. The Issuers will make all such calculations in good faith and, absent manifest error, their calculations will be final and binding on Holders. If requested by the Trustee, the Issuers will provide a schedule of its calculations to the Trustee and the Trustee is entitled to rely conclusively upon the accuracy of such calculations without independent verification.

The Issuers will pay interest, if any, semi-annually in arrears on May 1 and November 1 of each year, beginning May 1, 2024 (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is equal to the then applicable interest rate on the Notes to the extent lawful; the Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), from time to time on demand at the same rate to the extent lawful.

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. If any payment with respect to any principal of, premium, if any, on, or interest, if any, on any Note (including any payment to be made on any date fixed for redemption or purchase of any Note) is due on a day which is not a Business Day, then the payment need not be made on such date, but may be made on the next Business Day with the same force and effect as if made on such date, and no interest will accrue for the intervening period. If a regular record date is not a Business Day, then the record date shall not be affected.

(2) METHOD OF PAYMENT. The Issuers will pay interest on the Notes (except defaulted interest), if any, to the Persons who are registered Holders of Notes at the close of business on the April 15 and October 15 next preceding each Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the office or agency of the Issuers maintained for such purpose or, at the option of the Issuers, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium, if any, on, and interest, if any, on, all Global Notes and all other Notes the Holders of which hold not less than $5,000,000 aggregate principal amount of such other Notes in definitive from and will have provided wire transfer instructions to a U.S. dollar account in the contiguous United States to the Issuers or the Paying Agent.

A-6

(8) NOTICE OF REDEMPTION. At least 10 days but not more than 60 days before a redemption date, the Issuers will mail or cause to be mailed by first class mail (or sent electronically if DTC is the recipient), a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Article 8 or 11 thereof.

The Trustee may (but shall not be obligated to) withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, on, and interest, if any, on the Notes) if it determines that withholding notice is in their interest.
