On the date hereof, the Partnership is issuing $700,000,000 aggregate principal amount of its 7.034% Fixed/Floating Rate Junior Subordinated Notes due 2068 (the “Subordinated Notes”), which Subordinated Notes were issued pursuant to, and fully and unconditionally guaranteed by the Guarantor in accordance with, the Subordinated Indenture, dated as of October 4, 2004, as supplemented by the Ninth Supplemental Indenture dated as of May 24, 2007 (together, the “Subordinated Indenture”), among the Partnership, the Guarantor, and Xxxxx Fargo Bank, National Association, as trustee.

B. This Replacement Capital Covenant is the “Replacement Capital Covenant” referred to in the Prospectus Supplement, dated May 21, 2007, relating to the Subordinated Notes which supplements the Partnership’s Prospectus, dated March 23, 2005.

C. The Partnership and the Guarantor, in entering into and disclosing the content of this Replacement Capital Covenant in the manner provided below, are doing so with the intent that the covenants provided for in this Replacement Capital Covenant be enforceable by each Covered Debtholder and that the Partnership and the Guarantor be estopped from breaching the covenants in this Replacement Capital Covenant, in each case to the fullest extent permitted by applicable law.

D. The Partnership and the Guarantor acknowledge that reliance by each Covered Debtholder upon the covenants in this Replacement Capital Covenant is reasonable and foreseeable by the Partnership and the Guarantor and that the breach by the Partnership or the Guarantor of such covenants could result in injury or damages to a Covered Debtholder.

NOW, THEREFORE, the Partnership and the Guarantor hereby covenant and agree as follows in favor of and for the benefit of each Covered Debtholder.

SECTION 1. Definitions. Capitalized terms used in this Replacement Capital Covenant (including the Recitals) have the meanings set forth in Schedule I hereto.

SECTION 2. Limitations on Redemption, Repurchase, Defeasance or Purchase of Subordinated Notes. The Partnership and the Guarantor hereby promise and covenant to and for the benefit of each Covered Debtholder that the Partnership shall not redeem or repurchase,

or defease or discharge through the deposit of money and/or U.S. Government Obligations as contemplated by Article XI of the Subordinated Indenture (herein referred to as “defeasance”), any portion of the principal amount of the Subordinated Notes, and the Partnership and the Guarantor shall not purchase and shall cause their respective Subsidiaries not to purchase, all or any part of the Subordinated Notes, in each case, on or before the Termination Date, except to the extent that the principal amount repaid or defeased or the applicable repurchase, redemption or purchase price does not exceed the sum of the following amounts:

(i) the Applicable Percentage of (a) the aggregate amount of the net cash proceeds any member of the Partnership Group has received from the sale of Common Units and Subordinated Units and Rights to acquire Units; and (b) the Market Value of any of the Common Units or Subordinated Units that have been issued in connection with the conversion into or exchange for Common Units or Subordinated Units of any convertible or exchangeable securities, other than, in the case of clause (b), where the security into or for which such Common Units or Subordinated Units are convertible or exchangeable has received equivalent equity credit from any NRSRO; plus

(ii) the aggregate amount of net cash proceeds a member of the Partnership Group has received from the sale of Replacement Capital Securities (other than the securities set forth in clause (i) above);

in each case, to Persons other than a member of the Partnership Group within the applicable Measurement Period (it being understood that any such net cash proceeds or Market Value shall be applied only once to the redemption, repurchase, defeasance or purchase of Subordinated Notes, that the earliest net cash proceeds or Market Value in any Measurement Period shall be deemed applied first to any such redemption, repurchase, defeasance or purchase, and that any net cash proceeds or Market Value not so applied shall continue to be available in any other Measurement Period within which it falls); provided that the limitations in this Section 2 shall not restrict the redemption, repurchase, defeasance or purchase of any Subordinated Notes that have been previously repurchased, defeased or purchased in accordance with this Replacement Capital Covenant.

SECTION 3. Covered Debt.

(a) The Partnership and the Guarantor represent and warrant that the Initial Covered Debt is Eligible Debt.

(b) On or during the 30-day period immediately preceding any Redesignation Date with respect to the Covered Debt then in effect, the Partnership shall identify the series of Eligible Debt that will become the Covered Debt on and after such Redesignation Date in accordance with the following procedures:

(i) the Partnership shall identify each series of then outstanding long-term indebtedness for money borrowed that is Eligible Debt of the Partnership or, if the Partnership does not have any Eligible Debt outstanding, of the Guarantor;

(ii) if only one series of such then outstanding long-term indebtedness for money borrowed is Eligible Debt, such series shall become the Covered Debt commencing on such Redesignation Date;

(iii) if the Partnership or the Guarantor, as applicable, has more than one outstanding series of long-term indebtedness for money borrowed that is Eligible Debt, then the Partnership shall identify the series that has the latest occurring final maturity date as of the date the Partnership is applying the procedures in this Section 3(b) and such series shall become the Covered Debt on such Redesignation Date;

(iv) the series of outstanding long-term indebtedness for money borrowed that is determined to be Covered Debt pursuant to clause (ii) or (iii) above shall be the Covered Debt for purposes of this Replacement Capital Covenant for the period commencing on such Redesignation Date and continuing to but not including the Redesignation Date as of which a new series of outstanding long-term indebtedness is next determined to be the Covered Debt pursuant to the procedures set forth in this Section 3(b); and

(v) in connection with such identification of a new series of Covered Debt, the Partnership and the Guarantor shall give the notice provided for in Section 3(c) within the time frame provided for in such section.

Notwithstanding any other provisions of this Replacement Capital Covenant, if a series of Eligible Senior Debt of the Partnership or any Guarantor has become the Covered Debt in accordance with this Section 3(b), on the date on which the issuer of such Covered Debt issues a new series of Eligible Subordinated Debt, then immediately upon such issuance such new series of Eligible Subordinated Debt shall become the Covered Debt and the applicable series of Eligible Senior Debt shall cease to be the Covered Debt.

(c) Notice. In order to give effect to the intent of the Partnership and the Guarantor described in Recital C, the Partnership and the Guarantor covenant that (i) simultaneously with the execution of this Replacement Capital Covenant or as soon as practicable after the date hereof (x) notice shall be given to the Holders of the Initial Covered Debt and the trustee under the indenture or other instrument establishing such debt, in the manner provided in the indenture or such instrument, of this Replacement Capital Covenant and the rights granted to such Holders hereunder and (y) the Guarantor shall file a copy of this Replacement Capital Covenant with the Commission as an exhibit to a Current Report on Form 8-K under the Securities Exchange Act; (ii) so long as the Guarantor is a reporting issuer under the Securities Exchange Act, the Guarantor shall include in each annual report filed after the date hereof with the Commission on Form 10-K under the Securities Exchange Act a description of the covenant set forth in Section 2 and identify the series of long-term indebtedness for money borrowed that is Covered Debt as of the date such Form 10-K is filed with the Commission; (iii) if a series of the long-term indebtedness for money borrowed of the Partnership or the Guarantor (1) becomes Covered Debt or (2) ceases to be Covered Debt, the Partnership and the Guarantor shall give notice of such occurrence within 30 days to the Holders of such long-term indebtedness for money borrowed in the manner provided for in the indenture or other instrument under which such long-term indebtedness for money borrowed was issued and the

Guarantor shall report such change in a Current Report on Form 8-K (which shall include or incorporate by reference this Replacement Capital Covenant) and in the Guarantor’s next quarterly report on Form 10-Q or annual report on Form 10-K, as applicable; (iv) if, and only if, the Guarantor ceases to be a reporting company under the Securities Exchange Act, the Guarantor shall (A) post on its website the information otherwise required to be included in Securities Exchange Act filings pursuant to clauses (ii) and (iii) of this Section 3(c) and (B) cause a notice of the existence of this Replacement Capital Covenant to be posted on the Bloomberg screen for the Covered Debt or any successor Bloomberg screen and each similar third-party vendor’s screen the Guarantor reasonably believes is appropriate (each an “Investor Screen”) and use its commercially reasonable efforts to cause a hyperlink to a definitive copy of this Replacement Capital Covenant to be included on the Investor Screen for each series of Covered Debt, in each case to the extent permitted by Bloomberg or such similar third-party vendor, as the case may be; and (v) promptly upon request by any Holder of Covered Debt, such Holder will be provided with an executed copy of this Replacement Capital Covenant.

SECTION 4. Termination, Amendment and Waiver. (a) The obligations of the Partnership and the Guarantor pursuant to this Replacement Capital Covenant shall remain in full force and effect until the earliest date (the “Termination Date”) to occur of (i) 12:00 a.m. (New York, New York time) on January 15, 2038, or if earlier, the date on which the Subordinated Notes are otherwise paid, redeemed, defeased or purchased in full in accordance with this Replacement Capital Covenant, (ii) the date, if any, on which the Holders of a majority by principal amount of the then-effective series of Covered Debt consent or agree in writing to the termination of this Replacement Capital Covenant and the obligations of the Partnership and the Guarantor hereunder, (iii) the date on which none of the Partnership or the Guarantor has any series of outstanding Eligible Senior Debt or Eligible Subordinated Debt (in each case without giving effect to the rating requirement in clause (b) of the definition of each such term) and (iv) the date on which the Subordinated Notes are accelerated as a result of an event of default under the Subordinated Indenture. From and after the Termination Date, the obligations of the Partnership and the Guarantor pursuant to this Replacement Capital Covenant shall be of no further force and effect.

(b) This Replacement Capital Covenant may be amended or supplemented from time to time by a written instrument signed by the Partnership and the Guarantor with the consent of the Holders of a majority by principal amount of the then-effective series of Covered Debt, provided that this Replacement Capital Covenant may be amended or supplemented from time to time by a written instrument signed only by the Partnership and the Guarantor (and without the consent of any Holders of the then-effective series of Covered Debt) if any of the following apply (it being understood that any such amendment or supplement may fall into one or more of the following):

(i) such amendment or supplement eliminates Common Units or Subordinated Units (or Rights to acquire Units) as Replacement Capital Securities, if either (A) the Guarantor has been advised in writing by a nationally recognized independent accounting firm that or (B) an accounting standard or interpretive guidance of an existing accounting standard by an organization or regulator that has responsibility for establishing or interpreting accounting standards in the United States becomes effective such that, in each case, there is more than an insubstantial risk that the failure to

do so would result in a reduction in the Guarantor’s earnings per Common Unit or Subordinated Unit as calculated for financial reporting purposes,

(ii) the effect of such amendment or supplement is solely to impose additional restrictions on the ability of a member of the Partnership Group to redeem, repurchase, defease or purchase the Subordinated Notes or to impose additional restrictions on, or to eliminate certain of, the types of securities qualifying as Replacement Capital Securities and the Partnership and the Guarantor has delivered to the Holders of the then-effective series of Covered Debt in the manner provided for in the indenture or other instrument with respect to such Covered Debt a written certificate to that effect executed on its behalf by an officer of its general partner,

(iii) such amendment or supplement extends the date specified in Section 4 (a)(i), the Stepdown Date or both, or

(iv) such amendment or supplement is not adverse to the rights of the Covered Debtholders hereunder and the Partnership and the Guarantor has delivered to the Holders of the then-effective series of Covered Debt in the manner provided for in the indenture or other instrument with respect to such Covered Debt a written certificate executed on its behalf by an officer of its general partner stating that the Partnership and the Guarantor have determined that such amendment or supplement is not adverse to the Covered Debtholders. For the avoidance of doubt, an amendment or supplement that adds new types of Replacement Capital Securities or modifies the requirements of the Replacement Capital Securities described herein would not be adverse to the rights of the Covered Debtholders if, following such amendment or supplement, this Replacement Capital Covenant would satisfy clause (ii)(b) of the definition of Qualifying Replacement Capital Covenant.

(c) For purposes of Sections 4(a) and 4(b), the Holders whose consent or agreement is required to terminate, amend or supplement this Replacement Capital Covenant or the obligations of the Partnership hereunder shall be the Holders of the then-effective Covered Debt as of a record date established by the Partnership that is not more than 60 days prior to the date on which the Partnership proposes that such termination, amendment or supplement becomes effective.

SECTION 5. Miscellaneous. (a) This Replacement Capital Covenant shall be governed by and construed in accordance with the laws of the State of New York.

(b) This Replacement Capital Covenant shall be binding upon the Partnership and the Guarantor and their respective successors and assigns and shall inure to the benefit of the Covered Debtholders as they exist from time-to-time (it being understood and agreed by the Partnership and the Guarantor that any Person who is a Covered Debtholder, if such Person initiates a claim or proceeding to enforce its rights under this Replacement Capital Covenant after the Partnership or the Guarantor has violated its covenants in Section 2 and before the series of long-term indebtedness for money borrowed held by such Person is no longer Covered Debt, such Person’s rights under this Replacement Capital Covenant shall not terminate by reason of such series of long-term indebtedness for money borrowed no longer being Covered Debt until

the termination of such claim or proceeding). If at any time the Covered Debt is held by a trust (for example, where the Covered Debt is part of a an issuance of trust preferred securities), a holder of the securities issued by such trust may enforce (including by instituting legal proceedings) this Replacement Capital Covenant directly against the Partnership and the Guarantor as if such holder owned the Covered Debt Directly, and the holders of such trust securities shall be deemed Holders of Covered Debt for purposes of this Replacement Capital Covenant for so long as the indebtedness held by such trust remains Covered Debt hereunder. Other than the Covered Debtholders as provided in the previous two sentences, no other Person shall have any rights under this Replacement Capital Covenant or be deemed a third party beneficiary of or entitled to rely on this Replacement Capital Covenant. In particular, no holder of the Subordinated Notes is a third party beneficiary of this Replacement Capital Covenant, it being understood that the rights of the holders of the notes are set forth in the Subordinated Indenture.

(c) All demands, notices, requests and other communications to the Partnership or the Guarantor under this Replacement Capital Covenant shall be deemed to have been duly given and made if in writing and (i) if served by personal delivery upon the Partnership or the Guarantor, on the day so delivered (or, if such day is not a Business Day, the next succeeding Business Day), (ii) if delivered by registered post or certified mail, return receipt requested, or sent to the Partnership or the Guarantor by a national or international courier service, on the date of receipt by the Partnership or the Guarantor, as applicable (or, if such date of receipt is not a Business Day, the next succeeding Business Day), or (iii) if sent by telecopier, on the day telecopied, or if not a Business Day, the next succeeding Business Day, provided that the telecopy is promptly confirmed by telephone confirmation thereof, and in each case to the Partnership or the Guarantor at the address set forth below, or at such other address as the Partnership may thereafter notify to Covered Debtholders or post on its website as the address for notices under this Replacement Capital Covenant:
