Any such certificate or opinion of counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Partnership, the General Partner or the Guarantor, as the case may be, stating that the information with respect to such factual matters is in the possession of the Partnership, the General Partner or the Guarantor, as the case may be, unless such counsel knows that the certificate or opinion or representations with respect to such matters are erroneous.

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

Section 104. Acts of Holders; Record Dates

Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed (either physically or by means of a facsimile or an electronic transmission, provided that such electronic transmission is transmitted through the facilities of a Depositary) by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered (either physically or by means of a facsimile or an electronic transmission, provided that such electronic transmission is transmitted through the facilities of a Depositary) to the Trustee and, where it is hereby expressly required, to the Partnership or the Guarantors. 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 (subject to Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee, the Partnership and, if applicable, the Guarantors, if made in the manner provided in this Section.

Without limiting the generality of the foregoing, a Holder, including a Depositary that is a Holder of a Global Security, may make, give or take, by a proxy or proxies, duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders, and a Depositary that is a Holder of a Global Security may provide its proxy or proxies to the beneficial owners of interests in any such Global Security.

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 him 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 his 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.

The ownership, principal amount and serial numbers of Securities held by any Person, and the date of commencement of such Person’s holding the same, shall be proved by the Security Register.

Any request, demand, authorization, direction, notice, consent, waiver or other action of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Partnership or, if applicable, the Guarantors in reliance thereon, whether or not notation of such action is made upon such Security.

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

The Partnership may set any day as the record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given or taken by Holders of Securities of such series, but the Partnership shall have no obligation to do so. With regard to any record date set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date (or their duly appointed agents), and only such Persons, shall be entitled to give or take the relevant action, whether or not such Holders remain Holders after such record date.

Section 105. Notices, Etc., to Trustee, Partnership and Guarantors

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1) the Trustee by any Holder or by the Partnership or any Guarantor shall be sufficient for every purpose hereunder if made in writing and actually received by the Trustee at its office at 0000 Xxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, Attention: Corporate Trust Services, or at any other address previously furnished in writing by the Trustee, or

(2) the Partnership or any of the Guarantors by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Partnership addressed to it at 0000 Xxxxxxxxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, to the attention of the Corporate Secretary, or at any other address previously furnished in writing to the Trustee by the Partnership or any Guarantor.

Section 106. Notice to Holders; Waiver

Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid (if international mail, by air mail), to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice.

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 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.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Section 107. Conflict with Trust Indenture Act

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or excluded, as the case may be.

Section 108. Effect of Headings and Table of Contents

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 109. Successors and Assigns

All covenants and agreements in this Indenture by each of the Partnership and the Guarantors shall bind their respective successors and assigns, whether so expressed or not.

Section 110. Separability Clause

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

Section 111. Benefits of Indenture

Nothing in this Indenture or in the Securities or, if applicable, the Securities Guarantee, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, the holders of Senior Debt and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 112. Governing Law

This Indenture, the Securities and the Securities Guarantee shall be governed by and construed in accordance with the laws of the State of New York.

Section 113. Legal Holidays

In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities or, if applicable, the Securities Guarantee (other than a provision of the Securities of any series or, if applicable, the Securities Guarantee that specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

Section 114. 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 115. Interest Limitation

It is the intention of the Partnership to conform strictly to all applicable usury laws and any subsequent revisions, repeals or judicial interpretations thereof. Accordingly, if the transactions contemplated hereby would be usurious under any applicable law, then, in that event, notwithstanding anything to the contrary in the Securities or this Indenture, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under applicable law with respect to a Security shall under no circumstances exceed the maximum amount allowed by applicable law, and any excess shall be credited to the principal amount of such Security (or, if the principal amount of such Security shall have been paid in full, refunded to the Partnership), to the extent permitted by applicable law; and (ii) in the event that the maturity of any Security is accelerated or in the event of any redemption of such Security, then such consideration that constitutes interest under applicable law may never include more than the maximum amount allowed by applicable law, and any excess shall be credited to the principal amount of such Security (or, if the principal amount of such Security shall be paid in full, refunded to the Partnership), to the extent permitted by applicable law. All calculations made to compute the rate of interest with respect to a Security for the purpose of determining whether such rate exceeds the maximum amount allowed by applicable law shall be made, to the extent permitted by such applicable law, by allocating and spreading during the period of the full stated term of such Security all interest any time contracted for, taken, reserved, charged or received by such Holder or by the Trustee on behalf of any such Holder in connection therewith so that the amount or rate of interest charged for any and all periods of time during the term of the Security does not exceed the maximum amount or rate of interest allowed to be charged by law during the relevant period of time. Notwithstanding any of the foregoing, if at any

time applicable laws shall be changed so as to permit a higher rate or amount of interest to be charged than that permitted prior to such change, then unless prohibited by law, references in this Indenture or any Security to “applicable law” when used in the context of determining the maximum interest or rate of interest that can be charged shall be deemed to refer to such applicable law as so amended to allow the greater amount or rate of interest.

The right to accelerate maturity of any Security does not include the right to accelerate any interest which has not otherwise accrued to the date of such acceleration, provided, however, that the foregoing shall not prohibit the continuing accrual after acceleration of interest in accordance with the terms of the Indenture and such Security.

Section 116. Incorporators, Shareholders, Officers and Directors of the Partnership, the General Partner and the Guarantors Exempt from Individual Liability

No recourse under or upon any obligation, covenant or agreement of or contained in this Indenture or of or contained in any Security or, if applicable, the Securities Guarantee, or for any claim based thereon or otherwise in respect thereof, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, shareholder, member, officer, manager, employee, partner or director, as such, past, present or future, of the Partnership, the General Partner, any Guarantor or any successor Person, either directly or through the Partnership, the General Partner, any Guarantor or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a part of the consideration for, the execution of this Indenture and the issue of the Securities.

As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Partnership may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Partnership, [If applicable, insert — any Guarantor,] the Trustee and any agent of the Partnership [If applicable, insert —, a Guarantor] or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security is overdue, and none of the Partnership, [If applicable, insert — the Guarantors, ] the Trustee nor any such agent shall be affected by notice to the contrary.

Section 204. Global Securities

Every Global Security authenticated and delivered hereunder shall bear a legend in substantially the following form:

THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE TRANSFERRED TO, OR REGISTERED OR EXCHANGED FOR SECURITIES REGISTERED IN THE NAME OF, ANY PERSON OTHER THAN THE DEPOSITARY OR A NOMINEE THEREOF AND NO SUCH TRANSFER MAY BE REGISTERED, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. EVERY SECURITY AUTHENTICATED AND DELIVERED UPON REGISTRATION OF TRANSFER OF, OR IN EXCHANGE FOR OR IN LIEU OF, THIS SECURITY SHALL BE A GLOBAL SECURITY SUBJECT TO THE FOREGOING, EXCEPT IN SUCH LIMITED CIRCUMSTANCES.

If Securities of a series are issuable in whole or in part in the form of one or more Global Securities, as contemplated by Section 301, then, notwithstanding Clause (9) of Section 301 and the provisions of Section 302, any Global Security shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities from time to time endorsed

thereon and that the aggregate amount of Outstanding Securities represented thereby may from time to time be reduced or increased, as the case may be, to reflect exchanges. Any endorsement of a Global Security to reflect the amount, or any reduction or increase in the amount, of Outstanding Securities represented thereby shall be made in such manner and upon instructions given by such Person or Persons as shall be specified therein or in a Partnership Order. Subject to the provisions of Sections 303, 304 and 305, the Trustee shall deliver and redeliver any Global Security in the manner and upon instructions given by the Person or Persons specified therein or in the applicable Partnership Order. Any instructions by the Partnership with respect to endorsement or delivery or redelivery of a Global Security shall be in a Partnership Order (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel).

The provisions of the last sentence of Section 303 shall apply to any Security represented by a Global Security if such Security was never issued and sold by the Partnership and the Partnership delivers to the Trustee the Global Security together with a Partnership Order (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) with regard to the reduction or increase, as the case may be, in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of Section 303.

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution or Officers’ Certificate referred to above or in any such indenture supplemental hereto.

Any such Board Resolution or Officers’ Certificate referred to above with respect to Securities of any series filed with the Trustee on or before the initial issuance of the Securities of such series shall be incorporated herein by reference with respect to Securities of such series and shall thereafter be deemed to be a part of the Indenture for all purposes relating to Securities of such series as fully as if such Board Resolution or Officers’ Certificate were set forth herein in full.

All Securities of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of the Holders, for increases in the aggregate principal amount of such series of Securities and issuances of additional Securities of such series or for the establishment of additional terms with respect to the Securities of such series.

If any of the terms of the series are established by action taken by or pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by an authorized officer or other authorized person of the General Partner on behalf of the Partnership and, if applicable, the Guarantors and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth, or providing the manner for determining, the terms of the series.

With respect to Securities of a series subject to a Periodic Offering, such Board Resolution or Officers’ Certificate may provide general terms for Securities of such series and provide either that the specific terms of particular Securities of such series shall be specified in a Partnership Order, or that such terms shall be determined by the Partnership and, if applicable, the Guarantors, or one or more agents thereof designated in an Officers’ Certificate, in accordance with a Partnership Order.

Section 302. Denominations

The Securities of each series shall be issuable only in registered form without coupons in such denominations as shall be specified as contemplated by Section 301. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof.

Section 303. Execution, Authentication, Delivery and Dating

The Securities shall be executed on behalf of the Partnership by the Chairman of the Board, Vice Chairman, Chief Executive Officer, Chief Financial Officer, President or any Vice President of the General Partner and need not be attested. The signature of any of these officers on the Securities may be manual or facsimile. Any Securities Guarantee endorsed on the Securities shall be executed on behalf of the applicable Guarantor by its Chairman of the Board, its Chief Executive Officer, its President, its Chief Financial Officer or any of its Vice Presidents and need not be attested. The signature of any of these officers on any endorsement of the Securities Guarantee may be manual or facsimile.

Securities and any endorsement of a Securities Guarantee bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the General Partner shall bind the Partnership or who were at any time the proper officers of a Guarantor shall bind such Guarantor, in each case, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Partnership may deliver Securities of any series executed by the Partnership to the Trustee for authentication, together with a Partnership Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Partnership Order shall authenticate and deliver such Securities; provided, however, that in the case of Securities offered in a Periodic Offering, the Trustee shall authenticate and deliver such Securities from time to time in accordance with such other procedures (including, without limitation, the receipt by the Trustee of oral or electronic instructions from the Partnership or its duly authorized agents, thereafter promptly confirmed in writing) acceptable to the Trustee as may be specified by or pursuant to a Partnership Order delivered to the Trustee prior to the time of the first authentication of Securities of such series. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, in addition to any Officers’ Certificate and Opinion of Counsel required to be furnished to the Trustee pursuant to Section 102, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating,

(1) the form and terms (or the manner of determining the terms) of such Securities have been established by or pursuant to Board Resolution as permitted by Section 201, that such form or forms have been established in conformity with the provisions of this Indenture;

(2) if the terms of such Securities have been, or in the case of Securities of a series offered in a Periodic Offering, will be, established by or pursuant to a Board Resolution as permitted by Section 301, that such terms have been, or in the case of Securities of a series offered in a Periodic Offering, will be, established in conformity with the provisions of this Indenture, subject, in the case of Securities of a series offered in a Periodic Offering, to any conditions specified in such Opinion of Counsel (which conditions are reasonably acceptable to the Trustee); and

(3) that such Securities, when authenticated and delivered by the Trustee and issued by the Partnership in the manner and subject to any conditions specified in such Opinion of Counsel, which conditions are reasonably acceptable to the Trustee, will constitute valid and legally binding obligations of the Partnership and, if applicable, the Guarantors, enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles and entitled to the benefits of this Indenture, equally and ratably with all other Securities, if any, of such series Outstanding; and

(4) such other matters as the Trustee may reasonably request;

and, if the authentication and delivery relates to a new series of Securities created by an indenture supplemental hereto, also stating that all conditions precedent to the execution of the supplemental indenture with respect to that series of Securities have been complied with, the Partnership has the power to execute and deliver any such supplemental indenture and has taken all necessary action for those purposes and any such supplemental indenture has been executed and delivered and constitutes the legal, valid and binding obligation of the Partnership enforceable in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, fraudulent conveyance, moratorium or other laws and legal principles affecting creditors’ rights generally from time to time in effect and to general equitable principles, whether applied in an action at law or in equity).

If such form or forms or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Partnership Order and Opinion of Counsel or Board Resolution or supplemental indenture otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

With respect to Securities of a series not to be originally issued at one time, the Trustee may rely upon the Opinion of Counsel and the other documents delivered pursuant to Sections 201 and 301 and this Section, as applicable, in connection with the first authentication of Securities of such series and any subsequent request by the Partnership to the Trustee to authenticate Securities of such series upon original issuance shall constitute a representation and warranty by the Partnership that as of the date of such request, the statements made in the Officers’ Certificate shall be true and correct as if made on such date.

Each Security shall be dated the date of its authentication.

No Security, nor any Securities Guarantee endorsed thereon, shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of

authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Partnership, and the Partnership shall deliver such Security to the Trustee for cancellation as provided in Section 309 for all purposes of this Indenture, such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Section 304. Temporary Securities

Pending the preparation of Definitive Securities of any series, the Partnership may execute, and upon receipt of the documents required by Section 303, together with a Partnership Order, the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Definitive Securities of like series in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

If temporary Securities of any series are issued, the Partnership will cause Definitive Securities of that series to be prepared without unreasonable delay. After the preparation of Definitive Securities of such series, the temporary Securities of such series shall be exchangeable for Definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Partnership maintained pursuant to Section 1002 for the purpose of exchanges of Securities of such series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series the Partnership shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more Definitive Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. Until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as Definitive Securities of such series and tenor.

Section 305. Registration, Registration of Transfer and Exchange

The Partnership shall cause to be kept at an office or agency of the Security Registrar in The City of Houston a register (the register maintained in such office or in any other office or agency of the Partnership in a Place of Payment being herein sometimes referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Partnership shall provide for the registration of Securities and of transfers of Securities. The Partnership shall, prior to the issuance of any Securities hereunder, appoint the Trustee as the initial “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided and its Corporate Trust Office which, at the date hereof, is located at 0000 Xxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, Attention: Corporate Trust Services, as the initial office or agency in the City of Houston where the Security Register will be maintained. The Partnership may at any time replace such Security Registrar, change such office or agency or act as its own Security Registrar. The Partnership will give prompt written notice to the Trustee of any change of the Security Registrar or of the location of such office or agency. At all reasonable times the Security Register shall be available for inspection by the Trustee.

Upon surrender for registration of transfer of any Security of any series at the office or agency of the Partnership maintained pursuant to Section 1002 for such purpose, the Partnership and, if applicable, the Guarantors shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, with an endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, of any authorized denominations and of a like aggregate principal amount and tenor.

At the option of the Holder, Securities of any series (except a Global Security) may be exchanged for other Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Partnership and, if applicable, the Guarantors shall execute, and the Trustee shall authenticate and deliver, the Securities, with an endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, which the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Partnership and, if applicable, the Guarantors, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Partnership or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Partnership and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Partnership may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304 or 1107 not involving any transfer.

Neither the Trustee nor the Partnership shall be required (1) to issue, register the transfer of or exchange Securities of any series (or of any series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Securities of that series selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (2) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

Notwithstanding any other provision in this Indenture and except as otherwise specified as contemplated by Section 301, no Global Security may be transferred to, or registered or exchanged for Securities registered in the name of, any Person other than the Depositary for such Global Security or any nominee thereof, and no such transfer may be registered, except as provided in this paragraph. Every Security authenticated and delivered upon registration or transfer of, or in exchange for or in lieu of, a Global Security shall be a Global Security, except as provided in this paragraph. If (1) (A) the Depositary for a Global Security notifies the Partnership that it is unwilling or unable to continue as Depositary for such Global Security or ceases to be a clearing agency registered under the Exchange Act, and (B) a successor Depositary is not appointed by the Partnership within 90 days, (2) an Event of Default has occurred and is continuing with respect to the Securities of such series and the Security Registrar has received a request from the Depositary to issue certificated securities in lieu of all or a portion of the Global Securities of such series (in which case the Partnership shall deliver certificated securities within 30 days of such request) or (3) the Partnership determines in its sole discretion that Securities of a series issued in global form shall no longer be represented by a Global Security, then such Global Security may be exchanged by such Depositary for Definitive Securities of the same series, of any authorized denomination and of a like aggregate principal amount and tenor, registered in the names of, and the transfer of such Global Security or portion thereof may be registered to, such Persons as such Depositary shall direct.

Section 306. Mutilated, Destroyed, Lost and Stolen Securities

If any mutilated Security is surrendered to the Trustee, together with such security or indemnity as may be required by the Partnership, the Guarantors (if applicable) or the Trustee to save each of them and any agent of any of them harmless, the Partnership and, if applicable, the guarantors shall execute and, upon the Partnership’s request, the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series, with an endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, and of like tenor and principal amount and bearing a number not contemporaneously Outstanding.

If there shall be delivered to the Partnership, the Guarantors (if applicable) and the Trustee (1) evidence to their satisfaction of the destruction, loss or theft of any Security and (2) such security or indemnity as may be required by them to save each of them and any agent of any of them harmless, then, in the absence of notice to the Partnership or the Trustee that such Security has been acquired by a protected purchaser, the Partnership and, if applicable, the Guarantors shall execute and, upon the Partnership’s request, the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series, with an endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, and of like tenor and principal amount and bearing a number not contemporaneously Outstanding. If, after the delivery of such new Security, a protected purchaser of the original Security in lieu of which such new Security was issued presents for payment or registration

such original Security, the Trustee shall be entitled to recover such new Security from the party to whom it was delivered or any party taking therefrom, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Partnership and the Trustee in connection therewith.

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

Upon the issuance of any new Security under this Section, the Partnership may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security of any series issued pursuant to this Section in exchange for any mutilated Security or in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Partnership and, if applicable, the Guarantors, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

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

Section 307. Payment of Interest; Interest Rights Preserved

Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Partnership, at its election in each case, as provided in Clause (1) or (2) below:

(1) The Partnership may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Partnership shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Partnership shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Partnership of such Special Record Date and, in the name and at the expense of the Partnership, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2).

(2) The Partnership may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which such Securities may be listed or traded, and upon such notice as may

be required by such exchange, if, after notice given by the Partnership to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security, shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

For each series of Securities, the Partnership shall, prior to 10:30 a.m. (New York City time) on each payment date for principal and premium, if any, and interest, if any, deposit with the Trustee money in immediately available funds sufficient to make cash payments due on the applicable payment date.

Section 308. Persons Deemed Owners

Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, prior to due presentment of a Security for registration of transfer, the Partnership, the Trustee and, if applicable, the Guarantors and any agent thereof may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Sections 305 and 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Partnership, the Trustee nor, if applicable, the Guarantors nor any agent of any of them shall be affected by notice to the contrary.

No holder of any beneficial interest in any Global Security held on its behalf by a Depositary shall have any rights under this Indenture with respect to such Global Security, and such Depositary may be treated by the Partnership, the Trustee and, if applicable, the Guarantors and any agent thereof as the owner of such Global Security for all purposes whatsoever. None of the Partnership, the Trustee, nor, if applicable, the Guarantor nor any agent thereof will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Section 309. Cancellation

All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Partnership may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Partnership may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Partnership has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be disposed of in accordance with its customary procedures, and the Trustee shall thereafter deliver to the Partnership a certificate with respect to such disposition.

Section 311. CUSIP Numbers

The Partnership in issuing the Securities may use “CUSIP” numbers (in addition to the other identification numbers printed on the Securities), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such “CUSIP” numbers either as printed on the Securities or as contained in any notice of a

redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such “CUSIP” numbers. The Partnership will promptly notify the Trustee of any change in the “CUSIP” numbers.

(7) any other Event of Default provided as contemplated by Section 301 with respect to Securities of that series.

Section 502. Acceleration of Maturity; Rescission and Annulment

If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof) all of the Securities of that series to be due and payable immediately, by a notice in writing to the Partnership (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Partnership and the Trustee, may rescind and annul such declaration and its consequences if

(1) the Partnership or, if applicable, one or more of the Guarantors has paid or deposited with the Trustee a sum sufficient to pay

(A) all overdue interest on all Securities of that series,

(B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities,

(C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent Default or impair any right consequent thereon.

Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee

The Partnership covenants that if

(1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days (whether or not such payment is prohibited by the provisions of Article XV hereof), or

(2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof (whether or not such payment is prohibited by the provisions of Article XV hereof),

the Partnership will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, 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.

If the Partnership fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Partnership or, if applicable, the Guarantors or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Partnership or, if applicable, the Guarantors or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such

rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 504. Trustee May File Proofs of Claim

In case of any judicial proceeding relative to the Partnership or, if applicable, any Guarantor or any other obligor upon the Securities, their property or their creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official 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 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 607.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or, if applicable, the Securities Guarantee or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

Section 505. Trustee May Enforce Claims Without Possession of Securities

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

Section 506. Application of Money Collected

Any money or property collected or to be applied by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money or property on account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 607;

SECOND: Subject to Article XV hereof, to the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively; and

THIRD: The balance, if any, to the Partnership.

Section 507. Limitation on Suits

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture (including, if applicable, the Securities Guarantee) or a Security, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

(2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3) such Holder or Holders have offered and, if requested, provided to the Trustee reasonable security or indemnity against the costs, expenses and liabilities to be incurred in compliance with such request;

(4) the Trustee for 60 days after its receipt of such notice, request and offer and, if requested, provision of security or indemnity has failed to institute any such proceeding; and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

Section 508. Unconditional Right of Holders to Receive Principal, Premium and Interest

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Sections 305 and 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

Section 509. 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 in every such case, subject to any determination in such proceeding, the Partnership, the Guarantors, 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 had been instituted.

Section 510. Rights and Remedies Cumulative

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 511. Delay or Omission Not Waiver

No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event

of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 512. Control by Holders

Subject to the provisions of Section 603, the Holders of a majority in aggregate principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding or any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series; provided, however, that

(1) such direction shall not be in conflict with any rule of law or with this Indenture;

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and

(3) subject to the provisions of Section 601, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall determine that the proceeding so directed would involve the Trustee in personal liability or would otherwise be contrary to applicable law.

Section 513. Waiver of Past Defaults

The Holders of a majority in aggregate principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except

(1) a continuing default in the payment of the principal of or any premium or interest on any Security of such series, or

(2) a default in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 514. 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, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, however, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Trustee, in any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series to which the suit relates, or in any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security on or after the respective Stated Maturity expressed by such Security (or, in the case of redemption or repayment, on or after the Redemption Date).

ARTICLE VI

(2) in the absence of bad faith on its part, the Trustee may, with respect to Securities of such series, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture.

(b) In case an Event of Default with respect to any series of Securities has occurred and is continuing, the Trustee shall exercise with respect to the Securities of such series such rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent Person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(d) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

Section 602. Notice of Defaults

determine in good faith that withholding such notice is in the interests of Holders of Securities of such series; provided, further, however, that, in the case of any default or breach of the character specified in Section 501(3) with respect to the Securities of such series, no such notice to Holders shall be given until at least 60 days after the occurrence thereof.

(3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate;

(4) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may, without obligation to do so, make such further inquiry or investigation into such facts or matters as it may see fit; and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Partnership, personally or by agent or attorney;

Section 604. Not Responsible for Recitals or Issuance of Securities

The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Partnership or, if applicable, the Guarantors, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. Neither the Trustee nor any Authenticating Agent makes any representations as to the validity or sufficiency of this Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Partnership of Securities or the proceeds thereof.

Section 605. May Hold Securities

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Partnership or, if applicable, any Guarantor, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Partnership or, if applicable, the Guarantors with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

Section 606. Money Held in Trust

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Partnership or, if applicable, one or more of the Guarantors.

Section 607. Compensation and Reimbursement

The obligations of the Partnership under this Section to compensate the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder.

Without limiting any rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(4) or Section 501(5), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for such services are intended to constitute expenses of administration under any applicable Bankruptcy Law.

The provisions of this Section shall survive the satisfaction and discharge of this Indenture and the defeasance of the Securities.

Section 608. Disqualification; Conflicting Interests

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

Section 609. Corporate Trustee Required; Eligibility

There shall at all times be one or more Trustees hereunder with respect to the Securities of each series, at least one of which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus required by the Trust Indenture Act. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of a supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Partnership. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Partnership. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the removed Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If at any time:

(1) the Trustee shall fail to comply with Section 608 after written request therefor by the Partnership or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Partnership or by any such Holder, or

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (A) the Partnership, acting pursuant to the authority of a Board Resolution, may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Partnership, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those

series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Partnership and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Partnership. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Partnership or the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

The Partnership shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

Section 611. Acceptance of Appointment by Successor

(1) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Partnership, the Guarantors (if applicable) and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Partnership, any Guarantor (if applicable) or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

(2) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Partnership, the Guarantors (if applicable), the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (A) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (B) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (C) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees as co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, but, on request of the Partnership, any Guarantor (if applicable) or any successor Trustee, such retiring Trustee shall, upon payment of its charges, duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

(3) Upon request of any such successor Trustee, the Partnership, and, if applicable, the Guarantors shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (1) or (2) of this Section, as the case may be.

(4) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

Section 612. Merger, Conversion, Consolidation or Succession to Business

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 613. Preferential Collection of Claims Against the Partnership or the Guarantors

If and when the Trustee shall be or become a creditor of the Partnership, the Guarantors (if applicable) or any other obligor upon the Securities, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Partnership, the Guarantors (if applicable) or any such other obligor.

Section 614. Appointment of Authenticating Agent

The Trustee (upon notice to the Partnership) may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue (in accordance with procedures acceptable to the Trustee) and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Partnership and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of such Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or such Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Partnership and, if applicable, the Guarantors. The Trustee for any series of Securities may at any time terminate the

agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Partnership and, if applicable, the Guarantors. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Partnership and, if applicable, the Guarantors. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

Except with respect to an Authenticating Agent appointed at the request of the Partnership, the Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

COVENANTS

Section 1001. Payment of Principal, Premium and Interest

The Partnership will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Partnership in respect of the Securities of that series and this Indenture may be served. The Partnership 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 Partnership shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Partnership hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

The Partnership may also from time to time designate one or more other offices or agencies where the Securities of one or more series 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 shall in any manner relieve the Partnership of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Partnership 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.

Except as otherwise specified with respect to a series of Securities as contemplated by Section 301, the Partnership hereby initially designates as the Place of Payment for each series of Securities the City of Houston, and initially appoints the Trustee as Paying Agent at its Corporate Trust Office as the Partnership’s office or agency for each such purpose in such city.

Section 1003. Money for Securities Payments to Be Held in Trust

If the Partnership or any of its Subsidiaries shall at any time act as Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

Whenever the Partnership shall have one or more Paying Agents for any series of Securities, it will, on or prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Partnership will promptly notify the Trustee of its action or failure so to act.

The Partnership will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest, if any, on Securities of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any default by the Partnership (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest, if any, on the Securities of that series; and (3) during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.

The Partnership and, if applicable, the Guarantors may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Partnership Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Partnership or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Partnership 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.

Any money deposited with the Trustee or any Paying Agent in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the state which escheat laws control and the Trustee or any Paying Agent shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the state which escheat laws control for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Partnership as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may at the expense of the Partnership cause to be published once, in an Authorized Newspaper, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be paid to the state whose escheat laws control.

Section 1004. Statement by Officers as to Default

The Partnership and, if any Securities of a series to which Article XIV have been made applicable are Outstanding, each Guarantor will deliver to the Trustee, within 150 days after the end of each fiscal year of the Partnership ending after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signer or signers thereof the Partnership or the Guarantor, as the case may be, is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Partnership or the Guarantor, as the case may be, shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

Section 1005. Existence

Subject to Article VIII, the Partnership and, if any Securities of a series to which Article XIV has been made applicable are Outstanding, each Guarantor will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Partnership and, if applicable, each Guarantor shall not be required to preserve any such right or franchise if it shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Partnership or such Guarantor, as the case may be.

Section 1006. Waiver of Certain Covenants

The Partnership may omit in any particular instance to comply with any term, provision or condition set forth in Section 1005 with respect to the Securities of any series if before the time for such compliance the Holders of a majority in aggregate principal amount of the Outstanding Securities of all affected series (voting as one class) shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Partnership and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

A waiver which changes or eliminates any term, provision or condition of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such term, provision or condition, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.

ARTICLE XI

The election of the Partnership to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at the election of the Partnership of less than all the Securities of any series, the Partnership shall, not less than 35 nor more than 60 days prior to the Redemption Date fixed by the Partnership (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities (1) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, or (2) pursuant to an election of the Partnership which is subject to a condition specified in the terms of such Securities, the Partnership shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction or condition.

Section 1103. Selection by Trustee of Securities to be Redeemed

If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed), the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, on a pro rata basis or by any other method which the Trustee deems fair and appropriate and which complies with any securities exchange or other applicable requirements for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series.

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

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

Section 1104. Notice of Redemption

Notice of redemption shall be given by first-class mail (if international mail, by air mail), postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register.

(4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and that interest thereon will cease to accrue on and after said date,

(5) the place or places where such Securities are to be surrendered for payment of the Redemption Price, and

(6) that the redemption is for a sinking fund, if such is the case.

Notice of redemption of Securities to be redeemed shall be given by the Partnership or, at the Partnership’s request, by the Trustee in the name and at the expense of the Partnership.

Section 1105. Deposit of Redemption Price

On or prior to 10:30 a.m. New York City Time on any Redemption Date, the Partnership shall deposit with the Trustee or with a Paying Agent (or, if the Partnership is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date.

Section 1106. Securities Payable on Redemption Date

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Partnership shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Partnership at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

Section 1107. Securities Redeemed in Part

Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Partnership or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Partnership and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Partnership shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment.” If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

Section 1203. Redemption of Securities for Sinking Fund

Not less than 45 days prior to each sinking fund payment date for any series of Securities (unless a shorter period shall be satisfactory to the Trustee), the Partnership will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 1202 and stating the basis for such credit and that such Securities have not been previously so credited, and will also deliver to the Trustee any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Partnership in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

(1) The Partnership has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust, for the purposes of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Securities of such series (A) cash in an amount, or (B) in the case of any series of Securities the payments on which may only be made in legal coin or currency of the United States, U.S. Government Obligations, maturing as to principal and interest at such times and in such amounts as will insure the availability of cash, or (C) a combination thereof, certified to be sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay (i) the principal and interest and premium, if any, on all Securities of such series on each date that such principal, interest or premium, if any, is due and payable or on any Redemption Date established pursuant to Clause (3) below, and (ii) any mandatory sinking fund payments on the dates on which such payments are due and payable in accordance with the terms of the Indenture and the Securities of such series;

(2) The Partnership has delivered to the Trustee an Opinion of Counsel based on the fact that (A) the Partnership has received from, or there has been published by, the Internal Revenue Service a ruling, or (B) since the date hereof, there has been a change in the applicable federal income tax law, in

either case to the effect that, and such opinion shall confirm that, the Holders of the Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount and in the same manner and at the same times, as would have been the case if such deposit, defeasance and discharge had not occurred;

(3) If the Securities are to be redeemed prior to Stated Maturity (other than from mandatory sinking fund payments or analogous payments), notice of such redemption shall have been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee shall have been made;

(4) No Event of Default or event which with notice or lapse of time or both would become an Event of Default shall have occurred and be continuing on the date of such deposit;

(5) Such defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act);

(8) The Partnership has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to the defeasance contemplated by this provision have been complied with.

For this purpose, such covenant defeasance means that, with respect to the Securities of such series and any related Securities Guarantee, the Partnership and each of the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section, whether directly or indirectly by reason of any reference elsewhere herein to such Section or by reason of any reference in such Section to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 501, but, except as specified above, the remainder of this Indenture and the Securities of such series and any related Securities Guarantee shall be unaffected thereby. The following shall be the conditions to application of this Section 1303:

and dedicated solely to, the benefit of the Holders of the Securities of such series, (A) cash in an amount, or (B) in the case of any series of Securities the payments on which may only be made in legal coin or currency of the United States, U.S. Government Obligations, maturing as to principal and interest at such times and in such amounts as will insure the availability of cash, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay (i) the principal and interest and premium, if any, on all Securities of such series on each date that such principal, interest or premium, if any, is due and payable or on any Redemption Date established pursuant to Clause (2) below, and (ii) any mandatory sinking fund payments on the day on which such payments are due and payable in accordance with the terms of the Indenture and the Securities of such series;

(5) Such covenant defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act);

Subject to Sections 1302 and 1303, the Trustee shall promptly pay to the Partnership upon Partnership Order any moneys held by it at any time, 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 amounts required to effect the defeasance with respect to the Outstanding Securities in question.

The provisions of the last paragraph of Section 1003 shall apply to any money held by the Trustee or any Paying Agent under this Article that remains unclaimed for two years after the Maturity of any series of Securities for which money or U.S. Government Obligations have been deposited pursuant to Section 1302 or Section 1303.

Section 1306. Reinstatement

If the Trustee or the Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Partnership and the Guarantors under this Indenture and the Securities of the applicable series and the Securities Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Indenture until such time as the Trustee or the Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article; provided, however, that if the Partnership has made any payment of principal of or interest on any Securities of such series because of the reinstatement of its obligations, the Partnership shall be subrogated to the rights of Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or the Paying Agent.

ARTICLE XIV
GUARANTEE OF SECURITIES

Section 1401. Securities Guarantee

(1) Subject to the other provisions of this Article XIV, each of the Guarantors hereby jointly and severally guarantees to each Holder of a Security of each series to which this Article XIV has been made applicable as provided in Section 301(23) (the Securities of such series being referred to herein as the “Guaranteed Securities”) (which Security has been 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 Guaranteed Securities, or the obligations of the Partnership hereunder or thereunder, that:

(A) the principal of and premium, if any, and interest on the Guaranteed Securities will be promptly paid in full when due, whether at maturity, or by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Guaranteed Securities, if any, if lawful, and all other obligations of the Partnership to the Holders of Guaranteed Securities, or the Trustee hereunder or thereunder, will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(B) in case of any extension of time of payment or renewal of any Guaranteed Securities 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.

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

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

(4) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, to the extent permitted by applicable law, as between the Guarantors, on the one hand, and the Holders of Guaranteed Securities and the Trustee, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article V hereof for the purposes of this Securities Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such obligations as provided in Article V hereof, such obligations (regardless of whether due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Securities 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 Securities Guarantee.

Section 1402. Limitation on Guarantor Liability

Each Guarantor and, by its acceptance of Guaranteed Securities, each Holder thereof hereby confirms that it is the intention of all such parties that the Securities 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 Securities Guarantee. To effectuate the foregoing intention, the Holders and each Guarantor 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 XIV, result in the obligations of such Guarantor under its Securities Guarantee not constituting a fraudulent transfer or conveyance.

Section 1403. Execution and Delivery of Securities Guarantee Notation

To evidence its Securities Guarantee set forth in Section 1401 hereof, each Guarantor hereby agrees that a notation of such Securities Guarantee substantially in the form set forth in Section 203 or established in or pursuant to a Board Resolution or in an indenture supplemental hereto, in accordance with the provisions of Section 201, will be endorsed by an officer of such Guarantor on each Guaranteed Security authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its officers.

Each Guarantor hereby agrees that its Securities Guarantee set forth in Section 1401 hereof will remain in full force and effect notwithstanding any failure to endorse on each Guaranteed Security a notation of such Securities Guarantee.

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

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

ARTICLE XV
SUBORDINATION OF SECURITIES AND SECURITIES GUARANTEE

Section 1501. Securities and Securities Guarantee Subordinated to Senior Debt

The payment by the Partnership of the principal of, premium, if any, and interest, if any, on any series of Securities issued hereunder shall be subordinated to the extent set forth in an indenture supplemental hereto relating to such Securities.
