5

 

such Redemption Date on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury Yield plus 0.50%. The
Special Event Make-Whole Redemption Price, calculated as provided herein, shall be calculated and
certified to the Trustee and the Company by an Independent Investment Banker.

     “Three-Month LIBOR Rate” means, for each Quarterly Interest Period during the Floating
Rate Period, the rate (expressed as a percentage per year) for deposits in U.S. dollars for a
three-month period that appears on Reuters Page LIBOR01 as of 11:00 a.m. (London time) on the
second London Banking Day (the “LIBOR Interest Determination Date”) immediately preceding
the first day of such Quarterly Interest Period (the “LIBOR Rate Reset Date”). If such rate
does not appear on such page for the purpose of displaying offered rates of leading banks for
London interbank deposits in U.S. dollars, the Three-Month LIBOR Rate will be determined on the
basis of the rates, at approximately 11:00 a.m., London time, on the LIBOR Interest Determination
Date, at which U.S. dollar deposits with a maturity of three months in an amount determined by the
Calculation Agent as representative of a single transaction in the relevant market and at the
relevant time are offered by four major banks in the London interbank market selected and certified
to the Calculation Agent by the Company (“Reference Banks”) to prime banks in the London
interbank market for the interest period commencing on the LIBOR Rate Reset Date. The Company will
request the principal London office of each of the Reference Banks to provide a quotation of its
rate. If at least two quotations are provided as requested, the Three-Month LIBOR Rate will be the
arithmetic mean of the quotations. If fewer than two quotations are provided as requested, the
Three-Month LIBOR Rate will be the interest rate per annum equal to the average of the rates per
annum quoted by three major banks in New York City selected and certified to the Calculation Agent
by the Company, at or about 11:00 a.m., New York City time, on the LIBOR Interest Determination
Date, for loans in U.S. dollars to leading European banks in amounts that are representative of a
single transaction in the relevant market and at the relevant time with a maturity corresponding to
the interest period and commencing on the LIBOR Rate Reset Date. If fewer than three New York City
banks selected and certified to the Calculation Agent by the Company are quoting rates, the
Three-Month LIBOR Rate for the applicable interest period will be the same as for the immediately
preceding Quarterly Interest Period or, in the case of the Quarterly Interest Period beginning on
June 1, 2017, the interest rate on the Notes will be the same as for the most recent quarterly
period for which the Three-Month LIBOR Rate can be determined.

     “Treasury Yield” means, with respect to any Redemption Date, the rate per annum equal
to the semi-annual equivalent yield to maturity (computed as of the third Business Day immediately
preceding such Redemption Date) of the Comparable Treasury Issue, assuming a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the
applicable Comparable Treasury Price for such Redemption Date.

     “Trustee” means the Person named as the “Trustee” in the preamble of this Eighteenth
Supplemental Indenture until a successor Person shall have become such pursuant to the applicable
provisions of the Indenture, and thereafter “Trustee” shall mean such successor Person.

     Section 1.2 Rules of Construction. In addition to the Rules of Construction under Section 1.04 of the Base Indenture, the
following provisions also shall be applied wherever appropriate herein:

          (a) any references herein to a particular Section, Article, or Exhibit means a Section or
Article of, or an Exhibit to, this Eighteenth Supplemental Indenture unless otherwise expressly
stated herein; and

          (b) the Exhibits attached hereto are incorporated herein by reference and shall be considered
part of this Eighteenth Supplemental Indenture.

denominations of $1,000 in principal amount and integral multiples thereof.

     Section 2.2 Maturity. The principal amount of the Notes shall be payable on the maturity date of the Notes, which
is June 1, 2067.

     Section 2.3 Form. The Notes and the Trustee’s certificate of authentication thereon shall be substantially in
the form of Exhibit A.

     The Notes shall be issued only in registered form and, when issued, shall be registered in the
Debt Security Register of the Company. The Notes shall be originally issued in the form of one or
more Global Securities (the “Book-Entry Notes”). Each of the Book-Entry Notes shall
represent such of the Outstanding Notes as shall be specified therein and shall provide that it
shall represent the aggregate amount of Outstanding Notes from time to time endorsed thereon and
that the aggregate amount of Outstanding Notes represented thereby may from time to time be reduced
or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of Book-Entry
Notes to reflect the amount, or any increase or decrease in the amount, of Outstanding Notes
represented thereby shall be made by the Trustee in accordance with written instructions or such
other written form of instructions as is customary for the Depositary, from the Depositary or its
nominee on behalf of any Person having a beneficial interest in such Book-Entry Notes. The Company
initially appoints DTC to act as Depositary with respect to the Book-Entry Notes.

     Section 2.4 Registrar and Paying Agent. The Company initially appoints the Trustee as Registrar and paying agent with respect to the
Notes. The office or agency in the City and State of New York where the Notes may be presented for
registration of transfer or exchange and the Place of Payment for the Notes shall initially be the
corporate trust office of Wells Fargo Bank, National Association at 45 Broadway, 14th Floor, New
York, New York 10006.

     Section 2.5 Transfer and Exchange.

     The transfer and exchange of Book-Entry Notes or beneficial interests therein shall be
effected through the Depositary, in accordance with Section 2.15 of the Base Indenture and the
rules and procedures of the Depositary therefor.

     Section 2.6 Interest Rates; Payment of Principal and Interest.

          (a) Rates.

          (i) Interest During the Fixed Rate Period. During the Fixed Rate Period, (A) the
outstanding principal amount of the Notes and (B) to the extent permitted by applicable law,
any Deferred Interest or overdue interest thereon, will bear interest at a per annum rate
equal to the Fixed Rate until the commencement of the Floating Rate Period or, if earlier,
until the principal thereof and all Interest thereon is paid, compounded semi-annually and
payable (subject to the provisions of Article IV) semi-annually, in arrears on each
Semi-Annual Interest Payment Date.

          (ii) Interest During the Floating Rate Period. During the Floating Rate Period, (A) the
outstanding principal amount of the Notes and (B) to the extent permitted by applicable law,
any Deferred Interest or overdue interest thereon will bear interest during each Quarterly
Interest Period at a per annum rate equal to the applicable Floating Rate for such period,
until the principal thereof and all Interest thereon is paid, compounded quarterly and
payable (subject to the provisions of Article IV) quarterly in

7

 

arrears on each Quarterly
Interest Payment Date. The Calculation Agent will calculate the Floating Rate with respect
to each Floating Rate Period and the amount of Interest payable on each Quarterly Interest
Payment Date as promptly as practicable according to the appropriate method described
herein. Promptly upon such determination, the Calculation Agent will notify the Company and
the Trustee of the Floating Rate for the Floating Rate Period and the amount of Interest
payable to each Holder on each Quarterly Interest Payment Date. The Floating Rate determined
by the Calculation Agent, absent manifest error, will be binding and conclusive upon the
beneficial owners and Holders of the Notes, the Company and the Trustee.

          (b) Payment of Interest to Record Holders of the Notes. Payments of principal of,
premium, if any, and Interest due on the Notes representing Book-Entry Notes on any Interest
Payment Date, upon redemption or at maturity will be made available to the Trustee by 11:00 a.m.,
New York City time, on the applicable maturity date, Redemption Date, or Interest Payment Date,
unless such date falls on a day which is not a Business Day, in which case such payments will be
made available to the Trustee by 11:00 a.m., New York City time, on the next succeeding Business
Day; provided, however, that, during the Floating Rate Period, if such next
succeeding Business Day falls in the next succeeding calendar month, then such payments will be
made available to the Trustee by 11:00 a.m., New York City time, on the immediately preceding
Business Day. As soon as possible thereafter, the Trustee will make such payments to the
Depositary. Other than in connection with the maturity or redemption of the Notes or in connection
with payment of Defaulted Interest, Interest on the Notes may be paid only on an Interest Payment
Date. Payments of principal of, premium, if any, and Interest due on Notes other than Book-Entry
Notes on any Interest Payment Date, upon redemption or at maturity will be made in accordance with
Article II of the Base Indenture. The regular record date for Interest payable on the Notes on any
Interest Payment Date during the Fixed Rate Period shall be the May 15 or November 15, as the case
may be, immediately preceding such Interest Payment Date and during the Floating Rate Period shall
be the February 15, May 15, August 15 or November15, as the case may be, immediately preceding such
Interest Payment Date.

          (c) The amount of Interest payable on any Interest Payment Date during the Fixed Rate Period
will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of
Interest payable on any Interest Payment Date during the Floating Rate Period will be computed on
the basis of a 360-day year and the actual number of days elapsed.

          (d) To the extent permitted by applicable law, Interest not paid when due hereunder,
including, without limitation, all Deferred Interest and overdue Interest, shall in accordance with
Section 2.6(a), until paid, compound (i) semi-annually at the Fixed Rate on each Semi-Annual
Interest Payment Date during the Fixed Rate Period and (ii) quarterly at the applicable Floating
Rate on each Quarterly Interest Payment Date during the Floating Rate Period.

          (e) If the Company shall make a partial payment of Interest on any Interest Payment Date, such
payment shall, with respect to the Notes, be applied, first, to Deferred Interest until all such
Deferred Interest has been paid and, second, to any Current Interest.

          (f) To the extent that the provisions of this Section 2.6 are inconsistent with the provisions
of Article II of the Base Indenture, the provisions of this Section 2.6 shall control.

ARTICLE III

REDEMPTION OF THE NOTES

     Section 3.1 Optional Redemption. Subject to the provisions of Article III of the Base Indenture, the Company shall have the
option to redeem the Notes for cash:

          (a) in whole or in part, at any time and from time to time prior to June 1, 2017, at the
Make-Whole Redemption Price;

8

 

          (b) after the occurrence of a Special Event, in whole but not in part, at any time prior to
June 1, 2017, at the Special Event Make-Whole Redemption Price; and

          (c) in whole or in part, at any time and from time to time on or after June 1, 2017, at the
Optional Redemption Price.

     Section 3.2 Certain Redemption Procedures. Notes called for optional redemption shall become due on the Redemption Date. Notices of
optional redemption will be mailed at least 30 days but not more than 60 days before the Redemption
Date to each Holder of the Notes to be redeemed at its registered address. The notice of optional
redemption for the Notes will state, among other things, the amount of Notes to be redeemed, the
Redemption Date, the method of calculating such Redemption Price, and the place(s) that payment
will be made upon presentation and surrender of Notes to be redeemed. Unless the Company defaults
in payment of the Redemption Price or the paying agent is prohibited from making such payment
pursuant to the terms of Article XII of the Base Indenture, interest will cease to accrue on the
Redemption Date with respect to any Notes that have been called for optional redemption. If less
than all the Notes are redeemed at any time, the Trustee will select the Notes to be redeemed on a
pro rata basis or by any other method the Trustee deems fair and appropriate. The Company may not
redeem the Notes in part if the principal amount of the Notes has been accelerated and such
acceleration has not been rescinded unless all accrued and unpaid Interest (including Deferred
Interest) has been paid in full on all outstanding Notes for all Interest Periods terminating on or
before the Redemption Date.

     The Notes may be redeemed in part only in principal amounts that are integral multiples of $1,000.

     Section 3.3 No Sinking Fund. The Notes will not be entitled to the benefit of any sinking fund.

ARTICLE IV

DEFERRAL OF INTEREST

     Section 4.1 Optional Deferral of Interest.

          (a) The Company shall have the right, at any time and from time to time during the term of the
Notes, to elect to defer payment of all or any portion of any Current Interest and/or Deferred
Interest otherwise due on the Notes on any Interest Payment Date (“Optional Deferral”);
provided, however, that the Company may not (i) elect to defer payment of any
Interest otherwise due on any Interest Payment Date if, as a result of such deferral, the Company
shall have deferred payment of some or all of the Interest due on a number of consecutive Interest
Payment Dates with respect to a number of consecutive Interest Periods which, when taken together
as a single period, would equal or exceed ten (10) consecutive years, or (ii) elect to defer
payment of any Interest due on the maturity date of the Notes, or, with respect to any Notes being
redeemed, on the Redemption Date for such Notes. No Interest on the Notes shall be due and payable
on any Interest Payment Date during an Optional Deferral Period; however, Interest shall accrue on
the Notes during such period in accordance with Sections 2.6(a) and 2.6(d).

          (b) Following the termination of an Optional Deferral Period and the payment of all Deferred
Interest accrued during such Optional Deferral Period, the Company may again elect pursuant to
Section 4.1(a) to make an Optional Deferral of Interest.

          (c) On the Interest Payment Date on which the Company desires to terminate an Optional
Deferral Period or at the end of an Optional Deferral Period pursuant to clause (b) of the
definition of “Optional Deferral Period,” the Company shall pay all Deferred Interest and
Current Interest due on such Interest Payment Date. Such Interest shall be payable to the Holders
of the Notes in whose names the Notes are registered in the Debt Security Register for the Notes on
the record date with respect to such Interest Payment Date.

     Section 4.2 Notice of Deferrals.

          (a) The Company shall give written notice to the Trustee of any election of Optional Deferral
pursuant to Section 4.1 not fewer than ten (10) nor more than sixty (60) Business Days prior to the
applicable

9

 

Interest Payment Date for which Interest on the Notes will be deferred, other than an
Optional Deferral in the circumstances described in Section 4.2(b). The Trustee shall forward such
written notice promptly to each Holder of the Notes.

          (b) In the case of an election of Optional Deferral pursuant to Section 4.1 when the Company
or the Parent Guarantor would be prohibited pursuant to Section 12.03 of the Base Indenture from
paying Interest on the Notes, the Company shall give written notice to the Trustee of such election
of Optional Deferral not later than the time monies in respect of the Interest payment on the
applicable Interest Payment Date must be made available to the Trustee pursuant to Section 2.6(b)
hereof. The Trustee shall forward such written notice promptly to each Holder of the Notes.

ARTICLE V

CERTAIN COVENANTS

     Section 5.1 Covenants in Indenture. Holders of the Notes shall not have the benefit of and shall not be entitled to enforce the
covenants contained in Sections 4.12 and 4.13 of the Base Indenture.

     Section 5.2 Restricted Payments.

          (a) Subject to Section 5.2(b), during any Optional Deferral Period, (i) the Company and the
Parent Guarantor will not declare or make any distributions with respect to, or redeem, purchase,
or make a liquidation payment with respect to, any of their respective equity securities and (ii)
the Company and the Parent Guarantor will not, and will cause their respective Subsidiaries not to
(A) make any payment of interest, principal, or
premium, if any, on or repay, repurchase, or redeem any of the Company’s or the Parent
Guarantor’s debt securities (including securities similar to the Notes) that contractually rank
equally with or junior to the Notes or the Guarantee, respectively, or (B) make any payment under a
guarantee of the Company’s or the Parent Guarantor’s debt securities (including under a guarantee
of debt securities that are similar to the Notes) that contractually ranks equally with or junior
to the Notes or the Guarantee, respectively.

          (b) Notwithstanding the provisions of Section 5.2(a), the Company, the Parent Guarantor and
any of their respective Subsidiaries may take any of the following actions at any time, including
during an Optional Deferral Period: (i) make any purchase, redemption or other acquisition of any
equity securities in connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of employees, officers, directors, or agents, or a securities
purchase or dividend or distribution reinvestment plan, or the satisfaction of obligations pursuant
to any contract or security outstanding on the date that the Optional Deferral Period commences
requiring the purchase, redemption or acquisition of such equity securities; (ii) make any payment,
repayment, redemption, purchase, acquisition or declaration of a distribution as a result of a
reclassification of any of their respective equity securities or the exchange or conversion of all
or a portion of one class or series of such equity securities for another class or series of such
equity securities; (iii) purchase fractional interests in any of their respective equity securities
pursuant to the conversion or exchange provisions of such securities or the security being
converted or exchanged, in connection with the settlement of stock purchase contracts or in
connection with any split, reclassification or similar transaction; (iv) make a distribution paid
or made in any of their respective equity securities (or rights to acquire such equity securities),
or a repurchase, redemption or acquisition of such equity securities in connection with the
issuance or exchange of such equity securities (or of securities convertible into or exchangeable
for such equity securities) and distributions in connection with the settlement of securities
purchase contracts outstanding on the date that the Optional Deferral Period commences; (v) make
any redemption, exchange or repurchase of, or with respect to, any rights outstanding under a
rights plan or the declaration or payment thereunder of a distribution of or with respect to rights
in the future; (vi) make any payments under (A) the Notes and under securities similar to the Notes
(including trust preferred securities) that are (or, in the case of a trust preferred security, the
underlying debt obligation is) pari passu with the Notes and (B) the Guarantee and similar
guarantees associated with any instruments that are (or, in the case of a trust preferred security,
the underlying debt obligation is) pari passu with the Notes, in each case, so long as any such
payments are made on a pro rata basis with the Notes and the Guarantee, respectively; or (vii) make
any regularly scheduled dividend or distribution payments declared prior to the date that the
Optional Deferral Period commences.

10

 

          (c) Whether another security is similar to the Notes and whether another guarantee is similar
to the Guarantee for purposes of Section 5.2(b)(vi) shall be determined by the Company in its
reasonable discretion. For purposes of Section 5.2(b)(vi), the Subordinated Notes due 2066 and the
Subordinated Notes due 2068 are similar to the Notes and the Parent Guarantor’s guarantees of the
Subordinated Notes due 2066 and the Subordinated Notes due 2068 are similar to the Guarantee. For
purposes of Section 5.2(b)(iv) of the Amended and Restated Eighth Supplemental Indenture dated as
of August 25, 2006 and Section 5.2(b)(iv) of the Ninth Supplemental Indenture dated as of May 24,
2007, the Notes are similar to the Subordinated Notes due 2066 and the Subordinated Notes due 2068,
respectively, and the Guarantee is similar to the Parent Guarantor’s guarantees of the Subordinated
Notes due 2066 and the Subordinated Notes due 2068.

          (d) For the avoidance of doubt, nothing contained herein shall prevent the Company or the
Parent Guarantor from issuing any other securities, whether senior to, pari passu with or
subordinated to the Notes, including securities having covenants and provisions the same as or
similar to those applicable to the Notes, or any guarantees with respect thereto.

ARTICLE VI

Supplemental Indenture) of the Company on the terms and subject to the conditions set forth in
Article XII of the Base Indenture, and each Holder of Notes issued hereunder by such Holder’s
acceptance thereof acknowledges and agrees that all Notes shall be issued subject to the provisions
of this Article VI and such Article XII and that each Holder of Notes, whether upon original
issuance or upon transfer or assignment thereof, accepts and agrees to be bound by such provisions.
The Notes shall be “Subordinated Debt Securities” as such term is used in the Indenture,
and, for purposes of the Notes only, and not for purposes of any other Debt Securities, all
references in the Indenture to Senior Indebtedness of the Company shall mean Senior Indebtedness of
the Company as defined in this Eighteenth Supplemental Indenture.

          (b) The Notes shall be equal in rank and right of payment in all respects and are pari passu
with the Subordinated Notes due 2066 and the Subordinated Notes due 2068.

     Section 6.2 Amendment and Restatement of Section 12.02 of the Base Indenture. For purposes of the Notes only, and not for purposes of any other Debt Securities, Section
12.02 of the Base Indenture is hereby amended and restated in its entirety to read as follows:

     Section 12.02 Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution
of the assets of the Company to creditors upon a total or partial liquidation or a total or partial
dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to the Company or its property:

          (a) holders of Senior Indebtedness of the Company shall be entitled to receive payment in full
in cash of such Senior Indebtedness (including interest (if any), accruing on or after the
commencement of a proceeding in bankruptcy, whether or not allowed as a claim against the Company
in such bankruptcy proceeding) before Holders of Subordinated Debt Securities of the Company shall
be entitled to receive any payment of principal of, or premium, if any, or interest on, the
Subordinated Debt Securities; and

          (b) until the Senior Indebtedness of the Company is paid in full, any such distribution to
which Holders of Subordinated Debt Securities would be entitled but for this Article XII shall be
made to holders of Senior Indebtedness of the Company as their interests may appear, except that
such Holders may receive securities representing equity interests of the Company and any debt
securities of the Company that are subordinated to Senior Indebtedness of the Company to at least
the same extent as the Subordinated Debt Securities of the Company.

11

 

     Upon any payment or distribution of the assets of any Guarantor to creditors upon a total or
partial liquidation or a total or partial dissolution of such Guarantor or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to such Guarantor or its
property:

          (a) holders of Senior Indebtedness of such Guarantor shall be entitled to receive payment in
full in cash of such Senior Indebtedness (including interest (if any), accruing on or after the
commencement of a proceeding in bankruptcy, whether or not allowed as a claim against such
Guarantor in such bankruptcy proceeding) before Holders of Subordinated Debt Securities shall be
entitled to receive, under such Guarantor’s guarantee of such Subordinated Debt Securities, any
payment of principal of, or premium, if any, or interest on, the Subordinated Debt Securities; and

          (b) until the Senior Indebtedness of such Guarantor is paid in full, any such distribution to
which Holders of Subordinated Debt Securities would be entitled under such Guarantor’s guarantee
but for this Article XII shall be made to holders of Senior Indebtedness of such Guarantor as their
interests may appear, except that such Holders may receive securities representing equity interests
of such Guarantor and any debt securities of such Guarantor that are subordinated to Senior
Indebtedness of such Guarantor to at least the same extent as the guarantee of the Subordinated
Debt Securities of such Guarantor.

     Section 6.3 Amendment and Restatement of Section 12.03 of the Base Indenture. For purposes of the Notes only, and not for purposes of any other Debt Securities, Section
12.03 of the Base Indenture is hereby amended and restated in its entirety to read as follows:

     Section 12.03 Default on Senior Indebtedness. The Company may not pay the principal
of, or premium, if any, or interest on, the Subordinated Debt Securities or make any deposit
pursuant to Article XI and may not repurchase, redeem or otherwise retire any Subordinated Debt
Securities (collectively, “pay the Subordinated Debt Securities”) if (a) any principal, premium or
interest in respect of Senior Indebtedness of the Company is not paid when due, including any
applicable grace period (including at maturity) or (b) any other default on Senior Indebtedness of
the Company occurs and the maturity of such Senior Indebtedness is accelerated in accordance with
its terms unless, in either case, the default has been cured or waived and any such acceleration
has been rescinded or such Senior Indebtedness has been paid in full in cash; provided,
however, that the Company may pay the Subordinated Debt Securities without regard to the
foregoing if the Company and the Trustee receive written notice approving such payment from the
Representative of each issue of Designated Senior Indebtedness of the Company. During the
continuance of any default (other than a default described in clause (a) or (b) of the preceding
sentence) with respect to any Designated Senior Indebtedness of the Company pursuant to which the
maturity thereof may be accelerated immediately without further notice (except such notice as may
be required to effect such acceleration) or the expiration of any applicable grace periods, the
Company may not pay the Subordinated Debt Securities for a period (a “Payment Blockage
Period”) commencing upon the receipt by the Company and the Trustee of written notice of such
default from the Representative of any Designated Senior Indebtedness of the Company specifying an
election to effect a Payment Blockage Period (a “Blockage Notice”) and ending 179 days
thereafter (or earlier if such Payment Blockage Period is terminated by written notice to the
Trustee and the Company from the Person or Persons who gave such Blockage Notice, by repayment in
full in cash of such Designated Senior Indebtedness or because the default giving rise to such
Blockage Notice is no longer continuing). Notwithstanding the provisions described in the
immediately preceding sentence (but subject to the provisions contained in the first sentence of
this Section 12.03), unless the holders of such Designated Senior Indebtedness or the
Representative of such holders shall have accelerated the maturity of such Designated Senior
Indebtedness, the Company may resume payments on the Subordinated Debt Securities after such
Payment Blockage Period. Not more than one Blockage Notice may be given in any consecutive 360-day
period, irrespective of the number of defaults with respect to any number of issues of Designated
Senior Indebtedness during such period, unless otherwise specified pursuant to Section 2.03 for the
Subordinated Debt Securities of a series; provided, however, that in no event may
the total number of days during which any Payment Blockage Period or Periods is in effect exceed
179 days in the aggregate during any 360 consecutive day period. For purposes of this Section
12.03, no default or event of default which existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness of
the Company initiating such Payment Blockage Period shall be, or be made, the basis of the
commencement of a subsequent Payment Blockage Period by the Representative of such Designated
Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or
event of default shall have been cured or waived for a period of not less than 90 consecutive days.

12

 

     No Guarantor may make a payment or distribution in respect of its guarantee of any
Subordinated Debt Securities (“make a guarantee payment on Subordinated Debt Securities”) if (a)
any principal, premium or interest in respect of Senior Indebtedness of such Guarantor is not paid
when due, including any applicable grace period (including at maturity) or (b) any other default on
Senior Indebtedness of such Guarantor occurs and the maturity of such Senior Indebtedness is
accelerated in accordance with its terms unless, in either case, the default has been cured or
waived and any such acceleration has been rescinded or such Senior Indebtedness has been paid in
full in cash; provided, however, that such Guarantor may make a guarantee payment
on the Subordinated Debt Securities without regard to the foregoing if such Guarantor and the
Trustee receive written notice approving such payment from the Representative of each issue of
Designated Senior Indebtedness of such Guarantor. During the continuance of any default (other than
a default described in clause (a) or (b) of the preceding sentence) with respect to any Designated
Senior Indebtedness of such Guarantor pursuant to which the maturity thereof may be accelerated
immediately without further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, such Guarantor may not make a
guarantee payment on Subordinated Debt Securities for a period (a “Payment Blockage
Period”) commencing upon the receipt by such Guarantor and the Trustee of written notice of
such default from the Representative of any Designated Senior Indebtedness specifying an election
to effect a Payment Blockage Period (a “Blockage Notice”) and ending 179 days thereafter
(or earlier if such Payment Blockage Period is terminated by written notice to the Trustee and such
Guarantor from the Person or Persons who gave such Blockage Notice, by repayment in full in cash of
such Designated Senior Indebtedness or because the
default giving rise to such Blockage Notice is no longer continuing). Notwithstanding the
provisions described in the immediately preceding sentence (but subject to the provisions contained
in the first sentence of this paragraph of this Section 12.03), unless the holders of such
Designated Senior Indebtedness or the Representative of such holders shall have accelerated the
maturity of such Designated Senior Indebtedness, such Guarantor may resume payments under its
guarantee of any Subordinated Debt Securities after such Payment Blockage Period. Not more than one
Blockage Notice may be given in any consecutive 360-day period, irrespective of the number of
defaults with respect to any number of issues of Designated Senior Indebtedness during such period,
unless otherwise specified pursuant to Section 2.03 for the Subordinated Debt Securities of a
series; provided, however, that in no event may the total number of days during
which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during
any 360 consecutive day period. For purposes of this Section 12.03, no default or event of default
which existed or was continuing on the date of the commencement of any Payment Blockage Period with
respect to the Designated Senior Indebtedness of such Guarantor initiating such Payment Blockage
Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period
by the Representative of such Designated Senior Indebtedness, whether or not within a period of 360
consecutive days, unless such default or event of default shall have been cured or waived for a
period of not less than 90 consecutive days.

ARTICLE VII

Parent Guarantor. Initially, there shall be no Subsidiary Guarantors; provided,

4.14 of the Indenture, such Guarantee shall be subordinated in the same manner as the Guarantee of
the Parent Guarantor.

     Section 7.2 Ranking of the Guarantee.

          (a) The obligations of the Parent Guarantor under the Guarantee shall be subordinated to all

Holder of the Notes issued hereunder by such Holder’s acceptance thereof, acknowledges and agrees
that the Guarantee shall be issued subject to the provisions of this Section 7.2 and such Article
XII and that each Holder of Notes, whether upon original issuance or upon transfer or assignment
thereof, accepts and agrees to be bound by such provisions. The Guarantee of the Parent Guarantor
is a Guarantee of Subordinated Debt Securities, and, for purposes of the Notes only, and not for
purposes of any other Debt Securities, all references in the Indenture to Senior Indebtedness of
the Parent

13

 

Guarantor shall mean Senior Indebtedness, as defined in this Eighteenth Supplemental
Indenture, of the Parent Guarantor.

          (b) The Parent Guarantor’s obligation under the Guarantee shall be equal in rank and right of
payment in all respects and is pari passu with the Parent Guarantor’s guarantees of the
Subordinated Notes due 2066 and the Subordinated Notes due 2068.

ARTICLE VIII

APPLICABILITY OF DEFEASANCE AND COVENANT DEFEASANCE

     Section 8.1 Applicability of Defeasance and Covenant Defeasance. The Notes will be subject to satisfaction, defeasance and discharge pursuant to Article XI
of the Base Indenture in accordance with the provisions of such Article; provided that for
purposes of the Notes only, and not
for purposes of any other Debt Securities, (i) references in Section 11.02(b) of the Base
Indenture to Sections 6.01(d), (g) and (h) of the Base Indenture shall be deemed to be references
only to Section 6.01(d) of the Base Indenture, and that references in Section 11.02(b) of the Base
Indenture to Sections 6.01(e) and (f) of the Base Indenture shall not apply.

     Section 9.1 Amendment and Restatement of Section 6.01 of the Base Indenture. For purposes of the Notes only, and not for purposes of any other Debt Securities, Section

          (b) failure to pay Interest on the Notes when due and such default continues for thirty (30)

Eighteenth Supplemental Indenture is not a default in payment of Interest on the Notes);

          (c) the occurrence of a Bankruptcy Event with respect to the Company; or

          (d) the Guarantee ceases to be in full force and effect or is declared null and void in a
judicial proceeding;

then, and in each and every case that an Event of Default described in clause (a), (b), and (d)
with respect to the Notes at the time Outstanding occurs and is continuing, unless the principal
of, premium, if any, and Interest on all the Notes shall have already become due and payable,
either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes
then Outstanding hereunder, by notice in writing to the Company (and to the Trustee if given by
Holders), may, and the Trustee at the request of such Holders shall, declare the principal of,
premium, if any, and Interest on all the Notes to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable, anything in the Notes,
this Indenture or in the Eighteenth Supplemental Indenture contained to the contrary
notwithstanding. If an Event of Default described in clause (c) occurs, then and in each and every
such case, unless the principal of, premium, if any, and Interest on all the Notes shall have
become due and payable, the principal of, premium, if any, and Interest on all the Notes then
Outstanding hereunder shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders, anything in the Notes, this
Indenture or in the Eighteenth Supplemental Indenture contained to the contrary notwithstanding.

14

 

     The Holders of a majority in aggregate principal amount of the Notes then Outstanding by
written notice to the Trustee may rescind an acceleration and annul its consequences if the
rescission would not conflict with any judgment or decree of a court of competent jurisdiction
already rendered and if all existing Events of Default with respect to the Notes have been cured or
waived except nonpayment of principal, premium, if any, or Interest that has become due solely
because of acceleration. Upon any such rescission, the parties hereto shall be restored
respectively to their several positions and rights hereunder, and all rights, remedies, and powers
of the parties hereto shall continue as though no such proceeding had been taken.

     Section 9.2 Conforming Amendments. The reference in the last paragraph of Section 7.06 to Section 6.01(e) or (f) of the Base
Indenture shall be deemed to refer only to Section 6.01(c) of the Base Indenture.

any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions
of this Eighteenth

15

Indenture and the Notes shall be construed as if such invalid or illegal or unenforceable provision
had never been contained herein or therein.

     Section 10.8 Treatment of the Notes. By its acceptance of the Notes, each Holder and beneficial owner of the Notes agrees to
treat the Notes as indebtedness for all United States federal, state and local tax purposes.

which shall be an original, but such counterparts shall together constitute but one and the same
instrument.

     Section 10.10 Withholding. Notwithstanding any other provision of the Indenture or this Eighteenth Supplemental
Indenture to the contrary, each Holder and beneficial owner of the Notes hereby authorizes the
Company, if required by the Internal Revenue Code of 1986, as amended, or by any other applicable
legal requirement, to withhold any required amount from the amounts payable by the Company
hereunder to any Holder and/or beneficial owner of the Notes for payment to the appropriate taxing
authority. Any amount so withheld from such Person will be treated as a payment by the Company to
such Person, except as otherwise provided below. Each such Person agrees to file timely any
agreement that is required by any taxing authority in order to avoid any withholding obligation
that would otherwise be imposed on the Company. If the amount required to be withheld with respect
to such Person exceeds the amount payable to such Person, such excess will be treated as a demand
loan to such Person, payable within ten (10) days after such time that the Company makes payment to
the appropriate taxing authority and demand is made on such Person to pay same.

[REVERSE OF SECURITY]

ENTERPRISE PRODUCTS OPERATING LLC

7.000% FIXED/FLOATING RATE JUNIOR SUBORDINATED NOTES DUE 2067

     The Notes are one of a duly authorized issue of Debt Securities of the Company issued under
and pursuant to the Indenture, to which Indenture reference is hereby made for a description of the
rights, limitations of rights, obligations, duties, and immunities thereunder of the Trustee, the
Company, the Parent Guarantor and the Holders of the Debt Securities. The Debt Securities may be
issued in one or more series, which different series may be issued in various aggregate principal
amounts, may mature at different times, may bear interest (if any) at different rates, may be
subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as
provided in the Indenture. The Notes are of a series designated as the 7.000% Fixed/Floating Rate
Junior Subordinated Notes due 2067 of the Company (the “Notes”).

1. Interest.

     During the Fixed Rate Period, the outstanding principal amount hereof and (to the extent that
payment of such interest is enforceable under applicable law) any Deferred Interest or overdue
installment of Interest hereon will bear interest at the per annum rate of 7.000% payable (subject
to the provisions of the Indenture relating to Interest deferrals more fully described below)
semi-annually in arrears on June 1 and December 1 of each year commencing on December 1, 2009,
compounded semi-annually through the end of the Fixed Rate Period. During the Floating Rate Period,
the outstanding principal amount hereof and (to the extent that payment of such interest is
enforceable under applicable law) any Deferred Interest or overdue installment of Interest hereon
will bear interest during each Quarterly Interest Period at the applicable Floating Rate for such
Quarterly Interest Period calculated pursuant to the Indenture, payable (subject to the provisions
of the Indenture relating to Interest deferrals more fully described below) quarterly in arrears on
each March 1, June 1, September 1 and December 1, commencing September 1, 2017, compounded
quarterly at such prevailing Floating Rate through the end of the Floating Rate Period.

     During the Fixed Rate Period, the amount of Interest payable on any Interest Payment Date will
be computed on the basis of a 360-day year of twelve 30-day months. During the Floating Rate
Period, the amount of any Interest payable on any Interest Payment Date will be computed on the
basis of a 360-day year and the actual number of days elapsed. In the event that any date on which
Interest is payable on this Note is not a Business Day, then a payment of the Interest payable on
such date will, subject to certain exceptions described in the Eighteenth Supplemental Indenture,
be made on the next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), with the same force and effect as if made on the date the
payment was originally payable.

2. Optional Deferral of Interest.

     Subject to the terms of the Indenture, the Company shall have the right, at any time and from
time to time during the term of the Notes, to elect to defer payment of all or any portion of any
Current Interest and/or Deferred Interest otherwise due on the Notes on any Interest Payment Date.
No Interest on the Notes shall be due and payable on any Interest Payment Date during an Optional
Deferral Period; however, Interest shall accrue on the Notes during such period in accordance with
the Eighteenth Supplemental Indenture.

3. Method of Payment.

     The Company shall pay interest on the Notes (except Defaulted Interest) to the persons who are
the registered Holders at the close of business on the Regular Record Date immediately preceding
the Interest Payment Date. The Company shall pay principal, premium, if any, and interest in such
coin or currency of the United States of America as at the time of payment shall be legal tender
for payment of public and private debts. Payments in respect of a Global Security (including
principal, premium, if any, and interest) will be made by wire transfer of immediately available
funds to the accounts specified by the Depositary. Payments in respect of Notes in definitive

A-4

 

form (including principal, premium, if any, and interest) will be made at the office or agency
of the Company maintained for such purpose within The City of New York, which initially will be the
corporate trust office of Wells Fargo Bank, National Association at 45 Broadway, 14th Floor, New
York, New York 10006, or, at the option of the Company, payment of interest may be made by check
mailed to the Holders on the relevant record date at their addresses set forth in the Debt Security
Register of Holders or at the option of the Holder, payment of interest on Notes in definitive form
will be made by wire transfer of immediately available funds to any account maintained in the
United States, provided such Holder has requested such method of payment and provided timely wire
transfer instructions to the paying agent. The Holder must surrender these Notes to a paying agent
to collect payment of principal.

4. Paying Agent and Registrar.

     Initially, Wells Fargo Bank, National Association will act as paying agent and Registrar. The
Company may change any paying agent or Registrar at any time upon notice to the Trustee and the
Holders. The Company may act as paying agent.

5. Indenture.

     The Notes are one of a duly authorized issue of Debt Securities of the Company issued and to
be issued in one or more series under the Indenture.

     The terms of the Notes include those stated in the Indenture, those made part of the Indenture
by reference to the TIA, as in effect on the date of the Base Indenture (October 4, 2004), and
those terms stated in the Eighteenth Supplemental Indenture. The Notes are subject to all such
terms, and Holders of Securities are referred to the Indenture, the Eighteenth Supplemental
Indenture and the TIA for a statement of them. The Notes are junior subordinated obligations of the
Company and are not secured by any of the assets of the Company.

6. Denominations; Transfer; Exchange.

     The Notes are to be issued in registered form, without coupons, in denominations of $1,000 and
integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange,
Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture.

7. Person Deemed Owners.

     The registered Holder of Notes may be treated as the owner of it for all purposes.

8. Amendment; Supplement; Waiver.

     Subject to certain exceptions, the Indenture may be amended or supplemented, and any existing
Event of Default or compliance with any provision may be waived, with the consent of the Holders of
a majority in principal amount of the Outstanding Notes. Without consent of any Holder of Notes,
the parties thereto may amend or supplement the Indenture to, among other things, cure any
ambiguity or omission, to correct any defect or inconsistency, or to make any other change that
does not adversely affect the rights of any Holder of Notes. Any such consent or waiver by the
Holder of these Notes (unless revoked as provided in the Indenture) shall be conclusive and binding
upon such Holder and upon all future Holders and owners of these Notes and any Notes which may be
issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is
made upon these Notes or such other Notes.

9. Defaults and Remedies.

     Certain events of bankruptcy or insolvency respecting the Company are Events of Default that
will result in the principal amount of the Notes, together with premium, if any, and Interest
thereon, becoming due and payable immediately upon the occurrence of such Events of Default. If any
other Event of Default with respect to the Notes

A-5

 

occurs and is continuing, then in every such case the Trustee or the Holders of not less than
25% in aggregate principal amount of the Notes then Outstanding may declare the principal amount of
all the Notes, together with premium, if any, and Interest thereon, to be due and payable
immediately in the manner and with the effect provided in the Indenture. Notwithstanding the
preceding sentence, at any time after such a declaration of acceleration has been made, the Holders
of a majority in principal amount of the Outstanding Notes, by written notice to the Trustee, may
rescind such declaration and annul its consequences if the rescission would not conflict with any
judgment or decree of a court of competent jurisdiction already rendered and if all Events of
Default with respect to the Notes, other than the nonpayment of the principal, premium, if any, or
Interest which has become due solely by such declaration acceleration, shall have been cured or
shall have been waived. No such rescission shall affect any subsequent default or shall impair any
right consequent thereon. Holders of Notes may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may require reasonable indemnity or security before it
enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in
aggregate principal amount of the Notes then Outstanding may direct the Trustee in its exercise of
any trust or power.

10. Trustee Dealings with Company.

     The Trustee under the Indenture, in its individual or any other capacity, may make loans to,
accept deposits from, and perform services for the Company or its Affiliates or any subsidiary of
the Company’s Affiliates, and may otherwise deal with the Company or its Affiliates as if it were
not the Trustee.

11. Authentication.

     These Notes shall not be valid until the Trustee signs the certificate of authentication on
the other side of these Notes.

12. Abbreviations and Defined Terms.

     Customary abbreviations may be used in the name of a Holder of Notes or an assignee, such as:
TEN COM (tenant in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right
of survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to
Minors Act).

13. CUSIP Numbers.

     Pursuant to a recommendation promulgated by the Committee on Uniform Note Identification
Procedures, the Company has caused CUSIP numbers to be printed on the Notes as a convenience to the
Holders of the Notes. No representation is made as to the accuracy of such number as printed on the
Notes and reliance may be placed only on the other identification numbers printed hereon.

14. Absolute Obligation.

     No reference herein to the Indenture and no provision of the Notes or the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of, premium, if any, and interest on these Notes in the manner, at the respective times,
at the rate and in the coin or currency herein prescribed.

15. No Recourse.

     The sole manager of the Company and the general partner of the Parent Guarantor and their
respective directors, officers, employees, and members, as such, shall have no liability for any
obligations of any Guarantor or the Company under the Notes, the Indenture, or any Guarantee or for
any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder
by accepting the Notes waives and releases all such liability. The waiver and release are part of
the consideration for issuance of the Notes.

A-6

 

16. Ranking.

     The Notes rank junior and subordinate in rank and priority of payment to all of the Company’s
Senior Indebtedness as more fully provided in Article XII of the Base Indenture and Article VI of
the Eighteenth Supplemental Indenture. The Notes are equal in rank and right of payment in all
respects and are pari passu with the Company’s 8.375% Fixed/Floating Rate Junior Subordinated Notes
due 2066 and 7.034% Fixed/Floating Rate Junior Subordinated Notes due 2068.

17. Optional Redemption.

     The Notes are subject to redemption prior to maturity at the redemption price and in the
manner provided in the Indenture and the Eighteenth Supplemental Indenture.

18. Governing Law.

     The Notes shall be construed in accordance with and governed by the laws of the State of New
York.

19. Guarantee.

     Subject to Article XII of the Base Indenture and Articles VI and VII of the Eighteenth
Supplemental Indenture, the Notes are fully and unconditionally guaranteed on an unsecured basis by
the Parent Guarantor. The Parent Guarantor’s obligations under the Guarantee rank junior and
subordinate in rank and priority of payment to all of the Parent Guarantor’s Senior Indebtedness.
The Parent Guarantor’s obligation under the Guarantee is equal in rank and right of payment in all
respects and is pari passu with the Parent Guarantor’s guarantees of the Company’s 8.375%
Fixed/Floating Rate Junior Subordinated Notes due 2066 and 7.034% Fixed/Floating Rate Junior
Subordinated Notes due 2068.

20. Reliance.

     The Holder, by accepting these Notes, acknowledges (a) that such Holder has acquired Notes in
reliance upon the separateness of the Company, the sole manager of the Company and the Parent
Guarantor from one another and from any other Persons, including any Affiliates thereof, (b) that
the Company, the sole manager of the Company and the Parent Guarantor have assets and liabilities
that are separate from those of one another and from those of other persons, including any
Affiliates thereof, (c) that the Notes and other obligations owing under the Notes have not been
guaranteed by any Person, other than the Parent Guarantor and only to the extent explicitly set
forth herein, and (d) that, except in respect of the Parent Guarantor and as other Persons may
expressly assume or guarantee any of the Notes or obligations thereunder, the Holder shall look
solely to the Company and its property and assets for the payment of any amounts payable pursuant
to the Notes and for satisfaction of any obligations owing to the Holder.

Supplemental Indenture, the Parent Guarantor (which term includes any successor Person under the
Indenture), has fully, unconditionally and absolutely guaranteed, to the extent set forth in the
Indenture and subject to the provisions in the Indenture, the due and punctual payment of the

Indenture, and are subject to the provisions of Article XII of the Base Indenture and Section 7.2
of the Eighteenth Supplemental Indenture, and reference is hereby made to such documents for the
precise terms of the Guarantee.
