The Trustee may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any permanent Global Security held by a U.S. Depositary entitled under the procedures of such U.S. Depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture to be made, given or taken by Holders.

(4) If the Company shall solicit from the Holders of any Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may at its option (but is not obligated to), by Board Resolution, fix in advance a record date for the determination of Holders of Registered Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of Registered Securities of record at the close of business on such record date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders of Registered Securities shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

(5) Any request, demand, authorization, direction, notice, consent, waiver or other Act by 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 or suffered to be done by the Trustee, any Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Security.

Section 105 Notices, Etc. to Trustee, Company and any Guarantor.

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

(2) the Company or any Guarantor by the Trustee or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid or airmail postage prepaid if sent from outside the United States, to the Company or any Guarantor addressed to the attention of the Treasurer of the General Partner (with a copy to the General Counsel) at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company or such Guarantor.

The Trustee agrees to accept notice pursuant to this Section sent by unsecured facsimile transmission or electronic means; provided, however, that (1) the party providing such written notice, subsequent to such transmission of written notice, shall provide the originally executed notice to the Trustee in a timely manner, and (2) such originally executed notice shall be signed by an authorized representative of the party providing such notice; provided, further, that the Company shall provide to the Trustee an incumbency certificate listing such authorized representatives, which incumbency certificate shall be amended whenever a person is to be added or deleted from the listing. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reasonable reliance upon such notice notwithstanding any circumstance in which such notice is inconsistent with a subsequent notice.

Section 106 Notice to Holders of Securities; Waiver.

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of all or any series of any event, such notice shall be sufficiently given to Holders of Registered Securities of such series if in writing and mailed, first-class postage prepaid, to each Holder of a Registered Security affected by such event, at such Holder’s 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 of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities given as provided herein. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In the 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.

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 of Securities 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.

Securities bearing the manual, facsimile, or electronically-delivered signatures of individuals who were at any time the proper Officers of the General Partner shall bind the Company, 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 Company may deliver Securities, executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officer’s Certificate or supplemental indenture or indentures with respect to such Securities referred to in Section 301 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be provided with, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon an Opinion of Counsel and an Officer’s Certificate that contain the statements required by Section 102 and shall also be entitled to receive an Opinion of Counsel stating:

(1) if the form or forms of such Securities have been established by or pursuant to a 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 that are to be authenticated and delivered by the Trustee on original issue from time to time, 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 that are to be authenticated and delivered by the Trustee on original issue from time to time, will be, established in conformity with the provisions of this Indenture, subject, in the case of Securities of a series that are to be authenticated and delivered by the Trustee on original issue from time to time, to any conditions specified in such Opinion of Counsel; and

(3) that (a) such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company and (b) any Guarantees of such Securities, when such Securities have been so authenticated, delivered and issued, will constitute valid and legally binding obligations of the applicable Guarantor, in each case 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.

- 18 -

If such 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 second 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 Officer’s Certificate or Company Order otherwise required pursuant to such second preceding paragraph at or prior to the 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. This paragraph shall not be applicable to Securities of a series that are issued as part of a reopening pursuant to the last paragraph of Section 301.

Each Registered Security shall be dated the date of its authentication.

No Security 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 in Section 202 or Section 612 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of one of its authorized signatories. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company 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, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof that are printed, lithographed, typewritten, or otherwise produced, in any authorized denomination, substantially of the tenor of the Definitive Securities in lieu of which they are issued, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the Officers of the General Partner executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in the form of Global Securities.

Except in the case of temporary Global Securities, which shall be exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause Definitive Securities to be prepared without unreasonable delay. After the preparation of Definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such Definitive Securities upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of Definitive Securities of authorized denominations of the same series and containing identical terms and provisions. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary Global Security, 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.

Section 305 Registration, Transfer and Exchange.

With respect to the Registered Securities of each series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as the “ Security Register ”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Registered Securities of such series and of transfers of the Registered Securities of such series.

- 19 -

Such Office or Agency shall be the “ Security Registrar ” or “ Registrar ” for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities. The Company shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. If the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities.

A Global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Notwithstanding the foregoing, except as may be provided pursuant to Section 301, any Global Security or any beneficial interest therein shall be exchangeable for Definitive Securities only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary and a successor Depositary is not appointed by the Company within 90 days after the date the Company is so informed in writing, (ii) the Depositary ceases to be a clearing agency registered under the Exchange Act at a time when the Depositary is required to be so registered, and a successor Depositary is not appointed by the Company within 90 days after the date the Company becomes aware of such cessation, (iii) the Company (subject to the Applicable Procedures) executes and delivers to the Trustee a Company Order to the effect that such Global Security shall be so exchangeable or (iv) an Event of Default has occurred and is continuing with respect to such Securities and the Depositary requests the issuance of Definitive Securities in exchange for such Global Security. If the holder of a Global Security or the beneficial owners of interests in a Global Security are entitled to exchange such interests for Definitive Securities as the result of an event specified in clause (i), (ii), (iii) or (iv) of the preceding sentence, the Company shall promptly make available to the Trustee Definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such Global Security, executed by the Company. Such Global Security shall be surrendered from time to time by the U.S. Depositary or such other Depositary as shall be specified in the Company Order with respect thereto, and in accordance with instructions given to the Trustee and the U.S. Depositary or such other Depositary, as the case may be (which instructions shall be in writing but need not be contained in or accompanied by an Officer’s Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for Definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered Global Security, a like aggregate principal amount of Definitive Securities of the same series of authorized denominations and of like tenor as the portion of such Global Security to be exchanged; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date. Promptly following any such exchange in part, such Global Security shall be returned by the Trustee to such Depositary or the U.S. Depositary, as the case may be, or such other Depositary or U.S. Depositary referred to above in accordance with the instructions of the Company referred to above. If a Registered portion of a Global Security is exchanged for Definitive Registered Securities after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Definitive Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such Global Security shall be payable in accordance with the provisions of this Indenture.

The transfer and exchange of beneficial interests in the Global Securities shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Transfers and exchanges of beneficial interests in the Global Securities also shall require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following paragraphs, as applicable:

(1) Beneficial interests in any Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Global Security. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this subparagraph (1).

- 20 -

(2) In connection with the transfer or exchange of beneficial interests in any Global Security to Persons who take delivery thereof in the form of a beneficial interest in a different Global Security, the transferor of such beneficial interest must deliver to the Registrar (i) an order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Security in an amount equal to the beneficial interest to be transferred or exchanged and (ii) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Securities contained in this Indenture and such Securities or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Security(s) pursuant to this paragraph.

If any Holder of a beneficial interest in a Global Security proposes to exchange such beneficial interest for a Definitive Security or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Security in the event of the occurrence of any of the conditions set forth in the third paragraph of this Section 305, then, upon delivery to the Registrar of (i) an order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Security in an amount equal to the beneficial interest to be transferred or exchanged and (ii) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Security shall be registered to effect the transfer or exchange referred to in clause (i), the Trustee shall cause the aggregate principal amount of the applicable Global Security to be reduced accordingly as described below, and the Company shall execute and, upon receipt of a Company Order pursuant to Section 303, the Trustee shall authenticate and deliver to the Person designated in the instructions, a Definitive Security in the appropriate principal amount. Any Definitive Security issued in exchange for a beneficial interest pursuant to this paragraph shall be registered in such name or names and in such authorized denomination or denominations as the Holder of such beneficial interest shall instruct the Registrar through instructions from the Depositary and the Participant or Indirect Participant. The Trustee shall deliver such Definitive Securities to the Persons in whose names such Securities are so registered.

A Holder of a Definitive Security may exchange such Security for a beneficial interest in a Global Security or transfer such Definitive Securities to a Person who takes delivery thereof in the form of a beneficial interest in a Global Security at any time. Upon receipt of a request for such an exchange or transfer, the Trustee shall cancel the applicable Definitive Security and increase or cause to be increased the aggregate principal amount of the applicable Global Security.

At the option of the Holder, Definitive Securities of any series may be exchanged for other Definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Definitive Securities to be exchanged at an Office or Agency. Whenever any Definitive Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Definitive Securities which the Holder making the exchange is entitled to receive.

Upon request by a Holder of Definitive Securities and such Holder’s compliance with the provisions of this paragraph, the Registrar shall register the transfer or exchange of Definitive Securities. Prior to such registration of transfer or exchange, the requesting Holder shall present or surrender to the Registrar the Definitive Securities duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. A Holder of Definitive Securities may transfer such Securities to a Person who takes delivery thereof in the form of a Definitive Security. Upon receipt of a request to register such a transfer, the Registrar shall register the Definitive Securities pursuant to the instructions from the Holder thereof.

At such time as all beneficial interests in a particular Global Security have been exchanged for Definitive Securities or a particular Global Security has been redeemed, repurchased or cancelled in whole and not in part, each such Global Security shall be returned to or retained and cancelled by the Trustee in accordance with Section 309. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security or for Definitive Securities, the principal amount of Securities represented by such Global Security shall be reduced accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Depositary at the

- 21 -

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

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid and legally binding obligations of the Company evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange.

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

No service charge shall be made for any registration of transfer or exchange, or redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, Section 306, Section 906 and Section 1107 not involving any transfer.

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of selection of Securities of like tenor and the same series under Section 1103 for redemption and ending at the close of business on the day of such selection, (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except in the case of any Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to issue, register the transfer of or exchange any Security that, in accordance with its terms, has been surrendered for repayment or purchase at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

The Registrar shall retain copies of all certificates, notices and other written communications received pursuant to this Section 305. The Company shall have the right to inspect and make copies of all such certificates, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

All certifications and certificates required to be submitted to the Registrar pursuant to this Section 305 to effect a registration of transfer or exchange may (if acceptable to the Registrar) be submitted by facsimile or electronic means, with an original of such document to be sent promptly thereafter.

Section 306 Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security is surrendered to the Trustee, subject to the provisions of this Section 306, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding.

If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or to a Responsible Officer that such Security has been acquired by a “protected purchaser” (as such term is defined in the New York Uniform Commercial Code), the Company shall execute and, upon the Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such destroyed, lost or stolen Security, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding.

- 22 -

Notwithstanding the foregoing provisions of this Section 306, in case any mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section 306, the Company 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 issued pursuant to this Section 306 in lieu of any destroyed, lost or stolen Security shall constitute a separate obligation of the Company, whether or not the 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 such series duly issued hereunder.

The provisions of this Section 306, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, shall be 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 and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved.

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to, any Registered Security that shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest.

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to, any Registered Security that shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “ Defaulted Interest ”) shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be 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 Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on such Registered Security and the date of the proposed payment, and at the same time the Company 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 on or prior to the date of the proposed payment, which money when so deposited shall be held by the Trustee in trust for the benefit of the Person 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 Company of such Special Record Date and, in the name and at the expense of the Company, 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 the Holder of such Registered Security (or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

- 23 -

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

Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular series pursuant to the provisions of this Indenture, at the option of the Company, interest on Registered Securities that bear interest may be paid by wire transfer in immediately available funds if the Holder of the Registered Security has provided to the Company and the Trustee wire instructions at least five Business Days prior to the applicable payment date, or by check mailed to the address of that Holder as it appears on the books of the Securities Registrar if that Holder has not provided wire instructions; provided that any payment of principal (or premium, if any) in respect of any Security will be made only upon presentation and surrender of such Security at the applicable Office or Agency.

Subject to the foregoing provisions of this Section 307 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.

In the case of any Registered Security of any series that is convertible, which Registered Security is converted after any Regular Record Date and on or prior to the immediately succeeding Interest Payment Date (other than any Registered Security with respect to which the Maturity is prior to such Interest Payment Date), interest on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Registered Security (or one or more predecessor Registered Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Registered Security that is converted, interest with respect to which the Stated Maturity is after the date of conversion of such Registered Security shall not be payable.

Section 308 Persons Deemed Owners.

Prior to due presentment of a Registered Security for registration of transfer, the Company, any Guarantor, the Trustee and any agent of the Company, any Guarantor, or the Trustee may treat the Person in whose name such Registered Security is registered in the Security Register as the owner of such Registered Security for the purpose of receiving payment of principal of, any premium and (subject to Section 305 and Section 307) interest on, and any Additional Amounts with respect to, such Registered Security and for all other purposes whatsoever, whether or not any payment with respect to such Registered Security shall be overdue, and none of the Company, any Guarantor, the Trustee or any agent of the Company, any Guarantor, or the Trustee 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 Company, the Trustee and any agent of the Company or the Trustee as the owner of such Global Security for all purposes whatsoever. None of the Company, any Guarantor, the Trustee, any Paying Agent or the Security Registrar 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, exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities, as well as Securities surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 309, except as expressly permitted by or pursuant to this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures.

- 24 -

Section 310 Computation of Interest.

Except as otherwise provided in or pursuant to this Indenture, or in any Security, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months and interest on the Securities of each series for any partial period shall be computed on the basis of a 360-day year of twelve 30 day months and the number of days elapsed in any particular month.

Section 311 CUSIP and ISIN Numbers.

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

ARTICLE FOUR

(3) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with.

If there are Securities of two or more series hereunder, the Trustee shall be required to execute an instrument acknowledging satisfaction and discharge of this Indenture only if requested to do so with respect to Securities of such series as to which it is Trustee and if the other conditions thereto are met.

Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of Securities, the obligations of the Company to the Trustee under Section 607 and to an Authenticating Agent under Section 612, the obligations of the Trustee under Section 403, if money, Government Obligations or a combination thereof shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 401, the obligations of the Company and the Trustee with respect to the Securities of such series under Section 304, Section 305, Section 306, Section 1002 and Section 1003, and the obligations of the Company with respect to the payment of Additional Amounts, if any, with respect to such Securities as contemplated by Section 1004 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 401(1)(b)), and with respect to any rights to convert or exchange such Securities into Common Units or other securities, cash or other property, shall survive such satisfaction and discharge.

Section 402 Defeasance and Covenant Defeasance.

(1) Unless pursuant to Section 301, either or both of (i) defeasance of the Securities of a series under clause (2) of this Section 402 shall not be applicable with respect to the Securities of such series or (ii) covenant defeasance of the Securities of a series under clause (3) of this Section 402 shall not be applicable with respect to the Securities of such series, then such provisions, together with the other provisions of this Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities, and the Company may at its option by Board Resolution, at any time, with respect to such Securities, elect to have Section 402(2) or Section 402(3) be applied to such Outstanding Securities upon compliance with the conditions set forth below in this Section 402.

(2) Upon the Company’s exercise of the above option applicable to this Section 402(2) with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in clause (5) of this Section 402 are satisfied (hereinafter, “ defeasance ”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities, which shall thereafter be deemed to be “Outstanding” only for the purposes of the Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following, which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities to receive, solely from the trust fund described in clause (5) of this Section 402 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities when such payments are due, and any rights of such Holder to convert or exchange such Securities into Common Units or other securities, cash or other property, (ii) the obligations of the Company and the Trustee with respect to such Securities under Section 304, Section 305, Section 306, Section 1002 and Section 1003 and the obligations of the Company with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1004 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 402(5)(a) below), and with respect to any rights to convert or exchange such Securities into Common Units or other securities, cash or other property, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 402. The Company may exercise its option under this Section 402(2) notwithstanding the prior exercise of its option under clause (3) of this Section 402 with respect to such Securities.

- 26 -

(3) Upon the Company’s exercise of the above option applicable to this Section 402(3) with respect to any Securities of or within a series, (i) the Company shall be released from its obligations to comply with any term, provision or condition under Section 801 and Section 1007 with respect to such Securities (and, to the extent specified pursuant to Section 301, any other restrictive covenant added for the benefit of such Securities) and (ii) unless otherwise specified pursuant to Section 301, the occurrence of any event specified in Section 501(8), or with respect to the Guarantors only, the occurrence of any event specified in Section 501(5) or (6), shall not be deemed to be an Event of Default, in each case on and after the date the conditions set forth in clause (5) of this Section 402 are satisfied (hereinafter, “ covenant defeasance ”), and such Securities shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant or Event of Default, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities, the Company and, with respect to Securities of a particular series that are entitled to the benefit of the Guarantee, each Guarantor, may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth in any such covenant or Event of Default, whether directly or indirectly, by reason of any reference elsewhere herein to any covenant or by reason of reference in any such covenant 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(4), or Section 501(8) or otherwise, as the case may be, insofar as it relates to Section 801 or Section 1007 and, to the extent specified pursuant to Section 301, any other restrictive covenant added for the benefit of such Security, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby; provided that the obligations of the Company with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1004 shall remain unsatisfied only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 402(5)(a) below; provided, further, that notwithstanding a covenant defeasance with respect to Section 801 or Section 1007, any Person to whom a sale, assignment, transfer, lease, conveyance or other disposition is made pursuant to Section 801 or Section 1007, shall as a condition to such sale, assignment, transfer, lease, conveyance or other disposition, assume by an indenture supplemental hereto in form satisfactory to the Trustee, executed by such successor Person and delivered to the Trustee, the obligations of the Company to the Trustee under Section 607, the second to the last paragraph of Section 402 and the last sentence of Section 1004.

The Company shall maintain in each Place of Payment for any series of Securities an Office or Agency where Securities of such series may be presented or surrendered for payment, where Securities of such series may be surrendered for registration of transfer or exchange, where Securities of such series that are convertible or exchangeable may be surrendered for conversion or exchange, and where notices and demands to or upon the Company in respect of the Securities of such series relating thereto and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such Office or Agency.

The Company 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 Company of its obligation to maintain an Office or Agency in each Place of Payment for Securities of any series for such purposes. The Company shall 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.

Unless otherwise provided in or pursuant to this Indenture, the Company hereby designates as the Place of Payment for each series of Securities the Borough of Manhattan, The City of New York, and initially appoints the Corporate Trust Office of U.S. Bank National Association located at 100 Wall Street, New York, New York 10005, as the Office or Agency of the Company in the Borough of Manhattan, The City of New York for the foregoing purposes. The Company may subsequently appoint a different Office or Agency in the Borough of Manhattan, The City of New York for the Securities of any series.

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

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it shall, on or before each due date of the principal of, any premium or interest on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its failure so to act.

- 50 -

Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to each due date of the principal of, any premium or interest on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a sum (in the currency or currencies, currency unit or units or composite currency or currencies described in the preceding paragraph) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its failure so to act.

The Company shall 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 1003, that such Paying Agent shall:

(1) hold all sums held by it for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to Securities of such 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 provided in or pursuant to this Indenture;

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

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

Except as otherwise provided herein or pursuant hereto, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to any Security of any series and remaining unclaimed for two years after such principal or any such premium or interest or any such Additional Amounts shall have become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company either cause to be published once, in an Authorized Newspaper in each Place of Payment for such series, or may cause to be mailed once to Holders of Registered Securities of such series, 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 or mailing nor later than two years after such principal and any premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 1004 Additional Amounts.

If any Securities of a series provide for the payment of Additional Amounts, the Company shall pay to the Holder of any such Security Additional Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

Except as otherwise provided in or pursuant to this Indenture or the Securities of the applicable series, if the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which a payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned Officer’s Certificate, the Company shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officer’s Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium, if any, or interest on the Securities of such series shall be made to Holders of Securities of such series who are United States Aliens (as demonstrated by delivery of appropriate tax forms) without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of such series. If any such withholding shall be required, then such Officer’s Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities, and the Company shall pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officer’s Certificate furnished pursuant to this Section 1004.

Section 1005 Waiver of Certain Covenants.

The Company and the Guarantors may omit in any particular instance to comply with any term, provision or condition specified pursuant to Section 301 with respect to the Securities of any series if the Company shall have obtained or filed with the Trustee, prior to the time of such failure or omission, evidence (as described in Section 104) of the consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of such series, by Act of such Holders, either waiving such compliance in such instance or generally waiving 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 in accordance with Section 905, the obligations of the Company and the Guarantors and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

At or prior to 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit, with respect to the Securities of any series called for redemption pursuant to Section 1104, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 or in the Securities of such series) any accrued interest on and Additional Amounts with respect to such accrued interest, all such Securities or portions thereof which are to be redeemed on that date.

SINKING FUNDS

Section 1201 Applicability of Article.

The provisions of this Article Twelve shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture or any Security of such series issued pursuant to this Indenture.

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 such 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 and this Indenture.

Section 1202 Satisfaction of Sinking Fund Payments with Securities.

The Company may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver Outstanding Securities of such series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company) and (2) apply as a credit Securities of such series that have been redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, provided that such Securities have not been previously so credited. 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. If as a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to this Section 1202, the principal amount of

- 55 -

Securities of such series to be redeemed in order to satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee need not call Securities of such series for redemption, except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the request of the Company from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that series purchased by the Company having an unpaid principal amount equal to the cash payment requested to be released to the Company.

Section 1203 Redemption of Securities for Sinking Fund.

Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company shall deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, that is to be satisfied by payment of cash and the portion thereof, if any, that is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 1202, and the basis for such credit and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officer’s Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less than 60 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 Company 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 Section 1106 and Section 1107.

The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 309, shall not operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 1301, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers.

(3) The obligations of each of the Subsidiary Guarantors under this Article Sixteen shall be as aforesaid full, unconditional and absolute and shall not be impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (a) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of the Company or any of the Subsidiary Guarantors contained in the Securities or this Indenture, (b) any impairment, modification, release or limitation of the liability of the Company, any of the Subsidiary Guarantors or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable bankruptcy, insolvency, reorganization or other similar law, or other statute or from the decision of any court, (c) the assertion or exercise by the Company, any of the Subsidiary Guarantors or the Trustee of any rights or remedies under the Securities or this Indenture or their delay in or failure to assert or exercise any such rights or remedies, (d) the assignment or the purported assignment of any property as security for the Securities, including all or any part of the rights of the Company or any of the Subsidiary Guarantors under this Indenture, (e) the extension of the time for payment by the Company or any of the Subsidiary Guarantors of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of the Securities or this Indenture or of the time for performance by the Company or any of the Subsidiary Guarantors of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (f) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Company or any of the Subsidiary Guarantors set forth in this Indenture, (g) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, the Company or any of the Subsidiary Guarantors or any of their respective assets, or the disaffirmance of the Securities, the Subsidiary Guarantee or this Indenture in any such proceeding, (h) the release or discharge of the Company or any of the Subsidiary Guarantors from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (i) the unenforceability of the Securities, the Subsidiary Guarantee or this Indenture or (j) any other circumstances (other than payment in full or discharge of all amounts guaranteed pursuant to the Subsidiary Guarantee) that might otherwise constitute a legal or equitable discharge of a surety or guarantor.

(4) Each of the Subsidiary Guarantors hereby (a) waives diligence, presentment, demand of payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Company or any of the Subsidiary Guarantors, and all demands whatsoever, (b) acknowledges that any agreement, instrument or document evidencing the Subsidiary Guarantee may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Subsidiary Guarantee without notice to it and (c) covenants that the Subsidiary Guarantee will not be discharged except by complete performance of the Subsidiary Guarantee. Each of the Subsidiary Guarantors further agrees that if at any time all or any part of any payment theretofore applied by any Person to the Guarantee is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of the Company or any of the Subsidiary Guarantors, the Subsidiary Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, as though such application had not been made.

(5) Each of the Subsidiary Guarantors shall be subrogated to all rights of the Holders and the Trustee against the Company in respect of any amounts paid by such Subsidiary Guarantor pursuant to the provisions of this Indenture, provided, however, that such Subsidiary Guarantor, shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until all of the Securities and the Subsidiary Guarantee shall have been paid in full or discharged.

Section 1604 Execution and Delivery of Guarantee.

To further evidence a Guarantee set forth in this Article Sixteen, each of the Guarantors hereby agrees that a notation relating to such Guarantee (substantially in the form attached hereto as Annex A in the case of a Subsidiary Guarantee), shall be endorsed on each Security entitled to the benefits of the Guarantee authenticated and delivered by the Trustee and executed by either manual, facsimile or electronic signature of an officer of such Guarantor, or in the case of a Guarantor that is a limited partnership, an officer of the general partner of such Guarantor. Each of the Guarantors hereby agrees that the Guarantee set forth in this Article Sixteen shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to the Guarantee.

The Trustee hereby accepts the trusts in this Indenture upon the terms and conditions herein set forth.

Section 1605 Limitation on Guarantors’ Liability.

Each Guarantor and by its acceptance hereof each Holder of a Security entitled to the benefits of the Guarantee hereby confirm that it is the intention of all such parties that the guarantee by such Guarantor pursuant to the Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Federal or state law. To effectuate the foregoing intention, the Holders of a Security entitled to the benefits of the Guarantee and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under the Guarantee, not result in the obligations of such Guarantor under the Guarantee constituting a fraudulent conveyance or fraudulent transfer under Federal or state law.

Section 1606 Release of Guarantors from Guarantee.

(1) Notwithstanding any other provisions of this Indenture, the Guarantee of any Guarantor may be released upon the terms and subject to the conditions set forth in Section 402 and in this Section 1606 or, in any event, in accordance with the terms of such Guarantee or the supplement to this Indenture pursuant to which such Guarantee was issued. Provided that no Default shall have occurred and shall be continuing under this Indenture, the Guarantee incurred by a Guarantor pursuant to this Article Sixteen shall be unconditionally released and discharged (i) following delivery of an Officer’s Certificate to the Trustee to the effect that such release or discharge has occurred pursuant to the terms and conditions of any series of Securities covered by such Guarantee, or (ii) automatically upon (A) any sale, exchange or transfer, whether by way of merger or otherwise, to any Person that is not an Affiliate of the Company, of all of the Company’s direct or indirect limited partnership or other equity interests in such Guarantor (provided such sale, exchange or transfer is not prohibited by this Indenture) or (B) the merger of such Guarantor into the Company or any other Guarantor or the liquidation and dissolution of such Guarantor (to the extent such liquidation or dissolution is expressly permitted (without regard to Section 101(12)) by this Indenture or the applicable Securities).

(2) The Trustee shall deliver an appropriate instrument evidencing any release of a Guarantor from the Guarantee upon receipt of a written request of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel to the effect that the Guarantor is entitled to such release in accordance with the provisions of this Indenture. Any Guarantor not so released shall remain obligated under such Guarantee as provided in this Indenture, subject to the limitations of Section 1605.

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

The Guarantor guarantees (the “ Subordinated Guarantee of Collection ”) to the Trustee, for the ratable benefit of the Holders of the Guaranteed Notes, the full and prompt collection of the Company’s obligations under the Guaranteed Notes (each Holder, a “ Guaranteed Party ” and, collectively, the “ Guaranteed Parties ”) and the Company’s obligations under the Indenture with respect to the Guaranteed Notes (the “ Guaranteed Obligations ”). Such Subordinated Guarantee of Collection is a guaranty of collection only, and not a guaranty of payment.

Section 3.02 Exhaustion of Other Remedies Required . The obligations of the Guarantor hereunder are those of a secondary obligor, and not as primary obligor, and are dependent, in all respects, upon the Trustee, on behalf of the Guaranteed Parties, first pursuing and exhausting all rights and remedies, both legal and equitable, against the Company to collect payment upon the Guaranteed Obligations.

Section 3.03 Guaranteed Obligations Absolute . Except as otherwise provided in this First Supplemental Indenture, the Guarantor’s obligations under the Subordinated Guarantee of Collection are in all respects absolute and unconditional and shall not be impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation: (i) any amendment to, restatement of, supplement to or other modification of the Indenture in accordance with the terms thereof, or any furnishing, acceptance or release of any collateral for the Guaranteed Obligations or the addition, substitution or release of any other guarantor or any other entity or other Person primarily or secondarily liable in respect of the Guaranteed Obligations, (ii) any waiver, consent, extension, indulgence or other action or inaction under or in respect of the Indenture, (iii) any bankruptcy, insolvency, arrangement, reorganization, readjustment, composition, liquidation or similar proceeding with respect to the Company or its property, (iv) any merger, amalgamation or consolidation of any other guarantor or of the Company into or with any other Person or any sale, lease or transfer of any or all of the assets of any other guarantor or of the Company to any Person or (v) any other event or circumstance which might otherwise constitute a legal or equitable discharge or defense (other than repayment in full in cash of all the Guaranteed Obligations) of a guarantor (whether or not similar to the foregoing).

Section 3.04 Subordination .

(a) Any payment in respect of the Guaranteed Obligations is subordinated, to the extent and in the manner provided in this Section 3.04, to the prior payment in full of all CERC Senior Debt, whether outstanding at the date of this First Supplemental Indenture or thereafter created, incurred, assumed or guaranteed. These subordination provisions are for the benefit of the holders of CERC Senior Debt. This Section 3.04 shall constitute a continuing offer to all Persons who, in reliance upon such provisions, become holders of, or continue to hold, CERC Senior Debt, and such provisions are made for the benefit of the holders of CERC Senior Debt, and such holders are made obligees hereunder and any one or more of them may enforce such provisions.

16

(b) (i) No payment shall be made by or on behalf of the Guarantor on account of any of the Guaranteed Obligations in the event of default in payment of any principal of, premium (if any) or interest on any CERC Senior Debt when the same becomes due and payable, whether at maturity or at a date fixed for prepayment or by acceleration of maturity or otherwise (a “ Payment Default ”), unless and until such Payment Default has been cured or waived or otherwise has ceased to exist or such CERC Senior Debt has been discharged or paid in full.

(ii) No payment shall be made by or on behalf of the Guarantor on account of any of the Guaranteed Obligations in the event of any event of default (other than a Payment Default) with respect to any Designated CERC Senior Debt permitting the holders of such Designated CERC Senior Debt (or a trustee, agent or other representative on behalf of the holders thereof) to declare such Designated CERC Senior Debt due and payable prior to the date on which it would otherwise have become due and payable, upon written notice thereof to the Guarantor and the Trustee by any holders of Designated CERC Senior Debt (or a trustee, agent or other representative on behalf of the holders thereof) (a “ Payment Blocking Notice ”), unless and until such event of default has been cured or waived or otherwise has ceased to exist or such Designated CERC Senior Debt has been discharged or paid in full, provided, that such payments may not be prevented pursuant to this Section 3.04(b)(ii) for more than 179 days after an applicable Payment Blocking Notice has been received by the Trustee unless the Designated CERC Senior Debt in respect of which such event of default exists has been declared due and payable in its entirety, in which case no such payment may be made until such acceleration has been rescinded or annulled or such Designated CERC Senior Debt has been discharged or paid in full. No event of default that existed or was continuing on the date of any Payment Blocking Notice may be made the basis for the giving of a second Payment Blocking Notice, and only one such Payment Blocking Notice may be given in any 360-day period, irrespective of the number of defaults with respect to any number of issues of Designated CERC Senior Debt during such period.

(iii) In furtherance of the provisions of Section 3.04(a) of this First Supplemental Indenture, in the event that, notwithstanding the foregoing provisions of this Section 3.04(b), any payment or distribution of assets of the Guarantor shall be received by the Trustee for the benefit of any Guaranteed Party at a time when such payment or distribution was prohibited by the provisions of this Section 3.04(b) and the Trustee has received notice from the Guarantor or the Company that such payment or distribution was prohibited by the provisions of this Section 3.04(b), then, unless such payment or distribution has thereafter been paid or distributed by the Trustee or Paying Agent to the Guaranteed Party or is no longer prohibited by this Section 3.04(b), such payment or distribution shall be held in trust by the Trustee for the benefit of the holders of CERC Senior Debt, and upon direction from the Guarantor or the Company shall be paid or delivered by the Trustee to the holders of CERC Senior Debt remaining unpaid or unprovided for or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing such CERC Senior Debt may have been issued, it being understood that such payment or delivery shall be made ratably, according to the aggregate amounts remaining unpaid on account of such CERC Senior Debt held or represented by each, for application to the payment of all CERC Senior Debt in full after giving effect to all concurrent payments and distributions to or for the holders of such CERC Senior Debt.

(c) Upon any distribution of assets of the Guarantor or upon any dissolution, winding up, total or partial liquidation or reorganization of the Guarantor, whether voluntary or involuntary, in bankruptcy, insolvency, receivership or similar proceedings or upon any assignment for the benefit of creditors:

(i) the holders of all CERC Senior Debt shall first be entitled to receive payment in full of such CERC Senior Debt before any Guaranteed Party is entitled to receive any payment on account of the Guaranteed Obligations;

(ii) any payment or distribution of assets of the Guarantor of any kind or character, whether in cash, property or securities, to which any Guaranteed Party would be entitled, except for the provisions of this Section 3.04, shall be paid by the liquidating trustee or agent or other Person making such a payment or distribution directly to the holders of such CERC Senior Debt or their representative, ratably according to the respective amounts of CERC Senior Debt held or represented by each, to the extent necessary to make payment in full of all such CERC Senior Debt remaining unpaid after giving effect to all concurrent payments and distributions to the holders of such CERC Senior Debt;

17

(iii) in the event that, notwithstanding the foregoing provisions of this Section 3.04(c), (A) any payment or distribution of assets of the Guarantor of any kind or character, whether in cash, property or securities, shall be received by the Trustee for the benefit of any Guaranteed Party on account of any of the Guaranteed Obligations before all CERC Senior Debt is paid in full, (B) any holder of such CERC Senior Debt, notifies the Trustee of the amounts then due and owing on such CERC Senior Debt, if any, held by such holder (which notice shall be provided as promptly as practical following notice from the Guarantor or the Company or the liquidating trustee or agent to the holders of such CERC Senior Debt that such prohibited payment has been received by the Trustee), and (C) such payment or distribution has not thereafter been paid or distributed by the Trustee or Paying Agent to the Guaranteed Party, then such payment or distribution shall be received and held in trust by the Trustee for the benefit of the holders of such CERC Senior Debt, or their respective representatives, ratably according to the respective amounts of such CERC Senior Debt held or represented by each, to the extent necessary to make payment as provided herein of all such CERC Senior Debt remaining unpaid after giving effect to all concurrent payments and distributions and all provisions therefor to or for the holders of such CERC Senior Debt, and upon direction from the Guarantor or the Company, the Trustee shall pay only the amounts specified in such notice to the Trustee referred to in clause (B) to the holders of such CERC Senior Debt.

(d) (i) Subject to the payment in full of all CERC Senior Debt as provided herein, the Guaranteed Parties shall be subrogated (to the extent of the payments or distributions made to the holders of such CERC Senior Debt pursuant to the provisions of this Section 3.04) to the rights of the holders of such CERC Senior Debt to receive payments or distributions of assets of the Guarantor applicable to the CERC Senior Debt until release and discharge of the Subordinated Guarantee of Collection in accordance with Section 3.06 of this First Supplemental Indenture. For the purpose of such subrogation, no such payments or distributions to the holders of such CERC Senior Debt by the Guarantor or by or on behalf of the Guaranteed Parties by virtue of this Section 3.04, which otherwise would have been made to such Guaranteed Parties shall, as between the Guarantor and such Guaranteed Parties, be deemed to be payment by the Guarantor on account of such CERC Senior Debt, it being understood that the provisions of this Section 3.04 are, and are intended, solely for the purpose of defining the relative rights of the Guaranteed Parties, on the one hand, and the holders of such CERC Senior Debt, on the other hand.

(ii) If any payment or distribution to which any Guaranteed Party would otherwise have been entitled but for the provisions of this Section 3.04 shall have been applied, pursuant to the provisions of this Section 3.04, to the payment of amounts payable under CERC Senior Debt, then the Trustee, on behalf of such Guaranteed Party, shall be entitled to receive from the holders of such CERC Senior Debt any payments or distributions received by such holders of CERC Senior Debt in excess of the amount sufficient to pay all amounts payable under or in respect of such CERC Senior Debt in full and such amounts shall be paid and distributed by the Trustee or Paying Agent to the Guaranteed Party in accordance with the terms of the Indenture.

SECTION 3. Registered Exchange Offer .

(a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy, each of the Issuer and the Guarantor shall (i) use its commercially reasonable efforts to cause to be filed with the Commission after the Issue Date, a Registration Statement under the Securities Act relating to the Exchange Securities and the Exchange Offer, (ii) use its commercially reasonable efforts to cause such Registration Statement to become or be declared effective under the Securities Act, (iii) in connection with the foregoing, file (A) all pre-effective amendments to such Registration Statement as may be necessary in order to cause such Registration Statement to become or be declared effective, (B) if applicable, a post-effective amendment to such Registration Statement pursuant to Rule 430A under the Securities Act and (C) any necessary filings in connection with the registration and qualification of the Exchange Securities to be made under the state securities or blue sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, and (iv) promptly after such Registration Statement is declared effective by the Commission, commence the Exchange Offer. The Exchange Offer Registration Statement shall be on the appropriate form permitting (i) registration of the offer and issuance of the Exchange Securities to be offered in exchange for the Initial Securities that are Transfer Restricted Securities and (ii) resales of the Initial Securities by Broker-Dealers who currently hold Transfer Restricted Securities that were acquired for their own account as a result of market-making activities or other trading activities (other than Initial Securities acquired directly from the Issuer or any of its Affiliates) as contemplated by Section 3(c) below.

(b) Each of the Issuer and the Guarantor shall use its commercially reasonable efforts to cause the Exchange Offer Registration Statement to be effective continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable United States federal and state securities laws to Consummate the Exchange Offer; provided , however , that in no event shall such period be less than 20 Business Days after the date on which notice of the Exchange Offer is first mailed to the Holders. The Issuer and the Guarantor shall cause the Exchange Offer to comply with all applicable United States federal and state securities laws. No securities other than the Exchange Securities shall be included in the Exchange Offer Registration Statement. Each of the Issuer and the Guarantor shall use its commercially reasonable efforts to cause the Exchange Offer to be Consummated no later than 60 Business Days after the date on which the Exchange Offer Registration Statement has become effective, or such later date as may be required by United States federal securities laws.

(c) The Issuer shall indicate in a “Plan of Distribution” section contained in the Prospectus forming a part of the Exchange Offer Registration Statement that any Broker-Dealer who holds Initial Securities that are Transfer Restricted Securities that were acquired for its own account as a result of market-making activities or other trading activities (other than Transfer Restricted Securities acquired directly from the Issuer or any of its Affiliates), may exchange such Initial Securities pursuant to the Exchange Offer; however, such

5

Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Securities received by such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of Distribution” section shall also contain all other information with respect to such resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of Initial Securities held by any such Broker-Dealer except to the extent requested or required by the Commission.

Each of the Issuer and the Guarantor shall use its commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented and amended as required by the provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities acquired by any Broker-Dealer for its own account as a result of market-making activities or other trading activities, and to ensure that the Exchange Offer Registration Statement conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 180 days from the date on which the Exchange Offer Registration Statement is declared effective by the Commission and (ii) the date on which Broker-Dealers are no longer required to deliver a prospectus in connection with market-making or other trading activities.

The Issuer shall provide sufficient copies of the latest version of such Prospectus to Broker-Dealers promptly upon request at any time during such 180-day period (or a shorter period as provided in the foregoing sentence) in order to facilitate such resales.

SECTION 4. Shelf Registration.

(a) Shelf Registration . (a) If (i) the Issuer and the Guarantor are not required to file an Exchange Offer Registration Statement or to consummate the Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy, (ii) for any reason the Exchange Offer is not Consummated within 30 Business Days after the Effectiveness Target Date with respect to the Exchange Offer Registration Statement, or (iii) with respect to any Holder of Transfer Restricted Securities, such Holder notifies the Issuer prior to the 20th Business Day following the consummation of the Exchange Offer that (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer, (B) such Holder may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial Securities acquired directly from the Issuer or one of its Affiliates, then, upon such Holder’s request, each of the Issuer and the Guarantor shall:

(x) use its commercially reasonable efforts to cause to be filed a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “ Shelf Registration Statement ”), as promptly as reasonably practicable after the occurrence of (i), (ii) or (iii) of the first sentence of Section 4(a), which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and

(y) use its commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission.

6

Each of the Issuer and the Guarantor shall keep any such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities by the Holders of Transfer Restricted Securities entitled to the benefit of this Section 4(a), and to ensure that the Shelf Registration Statement conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, until the earlier of (i) one year following the effective date of such Shelf Registration Statement and (ii) the date on which all the Initial Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement or are distributed to the public pursuant to Rule 144 under the Securities Act or would be eligible to be sold by a Person that is not an “affiliate” (as defined in Rule 144) of the Issuer pursuant to Rule 144 without volume restriction (the “ Shelf Effectiveness Period ”).

(b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement . No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Issuer in writing, within 20 days after receipt of a request therefor, such information as the Issuer may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each Holder as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Issuer all information required to be disclosed in order to make the information previously furnished to the Issuer by such Holder true and correct in all material respects and not materially misleading.

SECTION 5. Registration Default . If a Registration Default occurs, the interest rate on the Transfer Restricted Securities will be increased by (i) 0.25% per annum for the first 90-day period beginning on the day immediately following such Registration Default, and (ii) an additional 0.25% per annum with respect to each subsequent 90-day period, in each case until and including the date such Registration Default ends, up to a maximum increase of 1.00% per annum. A Registration Default ends when the Initial Securities cease to be Transfer Restricted Securities or, if earlier, (1) in the case of a Registration Default under clause (i) of the definition thereof, when the Exchange Offer is completed, (2) in the case of a Registration Default under clause (ii) or clause (iii) of the definition thereof, when the Shelf Registration Statement becomes or is declared effective or (3) in the case of a Registration Default under clause (iv) or clause (v) of the definition thereof, when the Shelf Registration Statement again becomes effective or the Prospectus again becomes usable. If at any time more than one Registration Default has occurred and is continuing, then, until the next date that there is no Registration Default, the increase in interest rate provided for by this paragraph shall apply as if there occurred a single Registration Default that begins on the date that the earliest such Registration Default occurred and ends on such next date that there is no Registration Default. Notwithstanding the foregoing, the interest rate on the Transfer Restricted Securities will not increase because more than one Registration Default has occurred and is pending.

SECTION 6. Registration Procedures. Exchange Offer Registration Statement . (a) In connection with the Exchange Offer, the Issuer and the Guarantor shall comply with all of the provisions of Section 6(c) hereof and shall use commercially reasonable efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof. As a condition to its participation in the Exchange Offer pursuant to the terms of this Agreement, each Holder of Transfer Restricted Securities shall furnish, upon the request of the Issuer, prior to the Consummation thereof, a written representation to the Issuer (which may be contained in the letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an Affiliate of the Issuer or the Guarantor, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any Person to participate in, a distribution (within the meaning of the Securities Act) of the Exchange Securities to be issued in the Exchange Offer and (C) it is acquiring the Exchange Securities in its ordinary course of business. In addition, all such Holders of Transfer Restricted Securities shall otherwise cooperate in the Issuer’s preparations for the Exchange Offer. Each Holder, including any Holder that is a Broker-Dealer, shall acknowledge and agree that any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission enunciated in Morgan Stanley & Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters, and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Securities obtained by such Holder in exchange for Initial Securities acquired by such Holder directly from the Issuer or any of its Affiliates.

(b) Shelf Registration Statement . In connection with any Shelf Registration Statement, each of the Issuer and the Guarantor shall comply with all the provisions of Section 6(c) hereof and shall use commercially reasonable efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto each of the Issuer and the Guarantor will as promptly as reasonably practicable prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof.

If at any time the Commission shall issue any stop

9

order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or blue sky laws, each of the Issuer and the Guarantor shall use its commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time;

SECTION 7. Registration Expenses .

(a) All expenses incident to the Issuer’s performance of or compliance with this Agreement will be borne by the Issuer regardless of whether a Registration Statement becomes or is declared effective, including, without limitation: (i) all registration and filing fees and expenses (including filings made by any Initial Purchaser or Holder with FINRA (and, if applicable, the fees and expenses of any “qualified independent underwriter” and its counsel that may be required by the rules and regulations of FINRA)); (ii) all fees and expenses of compliance with United States federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing certificates for the Exchange Securities to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Issuer and, subject to Section 7(b) hereof, the Holders of Transfer Restricted Securities; and (v) all fees and disbursements of the Trustee and its counsel; and (vi) all fees and disbursements of independent certified public accountants of the Issuer (including the expenses of any special audit and comfort letters required by or incident to such performance).

SECTION 8. Indemnification .

(a) The Issuer agrees to indemnify and hold harmless (i) each Holder, (ii) each Person, if any, who controls any Holder within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act (a “ controlling person ”) and (iii) the respective officers, directors, partners, employees, representatives, affiliates and agents of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii), an “ Indemnified Holder ”), to the fullest extent lawful, from and against any loss, claim, damage, liability or expense, as incurred, to which an Indemnified Holder may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Issuer), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in any transaction contemplated hereby, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein (with respect to the Prospectus, in the light of the circumstances under which they were made) not misleading, and to reimburse each Indemnified Holder for any and all expenses (including the fees and disbursements of counsel chosen by such Indemnified Holder) as such expenses are reasonably incurred by such Indemnified Holder in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however , that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense (including without limitation and as incurred, reimbursement of all

15

reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending any claim or action, or any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to any such Indemnified Holder) to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Issuer by any of the Holders or the Guarantor expressly for use in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in any transaction contemplated hereby or arising out of or based upon any omission or alleged omission therefrom of a material fact necessary to make the statements therein (with respect to the Prospectus, in the light of the circumstances under which they were made) not misleading in conformity with written information furnished to the Issuer by such Holder or the Guarantor, as applicable, expressly for use therein or due to the failure of any Holder or the Guarantor to respond to any request for information by the Issuer. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Issuer may otherwise have.

(b) The Guarantor agrees to indemnify and hold harmless each Indemnified Holder, to the fullest extent lawful, from and against any loss, claim, damage, liability or expense, as incurred, to which an Indemnified Holder may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Guarantor), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in any transaction contemplated hereby, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein (with respect to the Prospectus, in the light of the circumstances under which they were made) not misleading, and to reimburse each Indemnified Holder for any and all expenses (including the fees and disbursements of counsel chosen by such Indemnified Holder) as such expenses are reasonably incurred by such Indemnified Holder in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however , that the foregoing indemnity agreement shall apply only to losses, claims, damages, liabilities or expenses caused by or resulting from information relating to the Guarantor furnished to the Issuer by the Guarantor and shall not apply to any loss, claim, damage, liability or expense (including without limitation and as incurred, reimbursement of all reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending any claim or action, or any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to any such Indemnified Holder) to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished by the Issuer or to the Issuer by any of the Holders expressly for use in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in any transaction contemplated hereby or arising out of or based upon any omission or alleged omission therefrom of a material fact necessary to make the statements therein (with respect to the Prospectus, in the light of the circumstances under which they were made) not misleading in

16

conformity with written information furnished by the Issuer or to the Issuer by such Holder expressly for use therein or due to the failure of any Holder to respond to any request for information by the Issuer. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that the Guarantor may otherwise have.

(c) Each Holder agrees, severally and not jointly, to indemnify and hold harmless each of the Issuer and the Guarantor and each of their respective officers, directors, partners, employees, representatives and agents, and each controlling person, to the fullest extent lawful, from and against any loss, claim, damage, liability or expense, as incurred, to which the Issuer, the Guarantor or any such officer, director, partner, employee, representative, agent or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Holder or such controlling person), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) (i) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in connection with any transaction contemplated hereby, or (ii) arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in connection with any transaction contemplated hereby, in reliance upon and in conformity with written information furnished to the Issuer by such Holder expressly for use therein or due to the failure of any Holder to respond to any request for information by the Issuer; and to reimburse the Issuer, the Guarantor or any such officer, director, partner, employee, representative, agent or controlling person for any legal and other expenses reasonably incurred by the Issuer, the Guarantor or any such officer, director, partner, employee, representative, agent or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 8(c) shall be in addition to any liabilities that such Holder may otherwise have. In no event shall the liability of any selling Holder hereunder be greater than the dollar amount of the proceeds received by such Holder upon the sale of the Transfer Restricted Securities giving rise to such indemnification obligation.

(d) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice

17

from such indemnified party, to assume, the defense thereof with counsel reasonably satisfactory to such indemnified party; provided , however , if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, which such approval shall not be unreasonably withheld, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel) representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party.

The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(e) If the indemnification provided for in this Section 8 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then, in lieu of such indemnification, each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer or the Guarantor, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Issuer shall be deemed to be equal to the total gross proceeds to the Issuer from the Initial Placement and the Registration Statement) or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuer or the Guarantor, on the one hand, and the

18

Holders, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Issuer or the Guarantor, on the one hand, and the Holders, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Issuer, the Guarantor or the Holders, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in this Section 8, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8(d) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made hereunder; provided , however , that no additional notice shall be required with respect to any action for which notice has been given under Section 8(d) for purposes of indemnification.

The Issuer, the Guarantor and each Holder of Transfer Restricted Securities agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8.

Notwithstanding the provisions of this Section 8, none of the Holders (or any Person who controls such Holder within the meaning of the Securities Act and the Exchange Act) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds received by such Holder from the sale of the Transfer Restricted Securities pursuant to a Registration Statement exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 8(e) are several, and not joint, in proportion to the respective principal amount of Initial Securities held by each of the Holders hereunder and not joint. For purposes of this Section 8(e), each director, officer and employee of each Holder and each Person, if any, who controls any Holder within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Holder, and each director, officer, employee, representative, affiliate and agent of the Issuer or the Guarantor, and each Person, if any, who controls the Issuer or the Guarantor within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such party.

SECTION 9. Rule 144A . Each of the Issuer and the Guarantor hereby agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding, to make available to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such

19

Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A under the Securities Act.

SECTION 10. Participation in Underwritten Registrations . No Holder may participate in any Underwritten Registration hereunder unless such Holder (a) agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

SECTION 11. Selection of Underwriters . The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker or investment bankers and manager or managers that will administer the offering will be selected by the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities included in such offering; provided , however , that such investment bankers and managers must be reasonably satisfactory to the Issuer.

SECTION 12. Miscellaneous .

(a) Remedies . Each of the Issuer and the Guarantor hereby agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

(b) Several Liability . The obligations of the Issuer and the Guarantor hereunder are several and not joint and neither the Issuer nor the Guarantor will be liable in any way for the other’s failure to perform any obligation hereunder. Any Indemnified Holder or other party seeking to recover under this Agreement from the Issuer or the Guarantor for any failure to perform any obligation hereunder shall only have a right to recover from the party whose failure is the subject of the claim.

(c) No Inconsistent Agreements . Neither the Issuer nor the Guarantor will, on or after the date of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Neither the Issuer nor the Guarantor has previously entered into any agreement granting any registration rights with respect to its securities to any Person pursuant to which any such Person would have the right to include any securities in any Registration Statement to be filed with the Commission as required under this Agreement. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Issuer’s or the Guarantor’s securities under any agreement in effect on the date hereof.

(d) Adjustments Affecting the Securities . Neither the Issuer nor the Guarantor will take any action, or permit any change to occur, with respect to the Initial Securities and/or the Exchange Securities that would materially and adversely affect its ability to Consummate the Exchange Offer.

20

(e) Amendments and Waivers . The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Issuer has obtained the written consent of Holders of a majority of the then-outstanding aggregate principal amount of Transfer Restricted Securities or a confirmation from DTC that the Holders of a majority of the then-outstanding aggregate principal amount of Transfer Restricted Securities has consented. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Transfer Restricted Securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders whose securities are not being sold pursuant to such Registration Statement may be given by the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities being sold by such Holders pursuant to such Registration Statement; provided that the provisions of this sentence may not be amended, modified or supplemented except in accordance with the provisions of the immediately preceding sentence; provided further that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Issuer shall obtain the written consent of each such Initial Purchaser (which consent shall not be unreasonably withheld) with respect to which such amendment, supplement, waiver or consent is to be effective. Notwithstanding the preceding two sentences, Sections 5 and 8 hereof shall not be amended, modified or supplemented, and waivers or consents to depart from this sentence may not be given, unless the Issuer has obtained the written consent of each Holder affected thereby.

(f) Notices . All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, telecopier, or air courier guaranteeing overnight delivery:
