ARTICLE II

DEBT SECURITIES

          Section 2.01. Authentication and Dating.

          Upon the execution and delivery of this Indenture, or from time to time thereafter, Debt
Securities in an aggregate principal amount not in excess of $10,310,000 may be executed and
delivered by the Company to the Trustee for authentication, and the Trustee shall thereupon
authenticate and make available for delivery said Debt Securities to or upon the written order of
the Company, signed by its Chairman of the Board of Directors, Vice Chairman, President or Chief
Financial Officer or one of its Vice Presidents, without any further action by the Company
hereunder. In authenticating such Debt Securities, and accepting the additional responsibilities
under this Indenture in relation to such Debt Securities, the Trustee shall be entitled to receive,
and (subject to Section 6.01) shall be fully protected in relying upon a copy of any Board
Resolution or Board Resolutions relating thereto and, if applicable, an appropriate record of any
action taken pursuant to such resolution, in each case certified by the Secretary or an Assistant
Secretary or other officer with appropriate delegated authority of the Company as the case may be.

          The Trustee shall have the right to decline to authenticate and deliver any Debt Securities
under this Section if the Trustee, being advised by counsel, determines that such action may not
lawfully be taken or if a Responsible Officer of the Trustee in good faith shall determine that
such action would expose the Trustee to personal liability to existing securityholders.

          The definitive Debt Securities shall be typed, printed, lithographed or engraved on steel
engraved borders or may be produced in any other manner, all as determined by the officers
executing such Debt Securities, as evidenced by their execution of such Debt Securities.

          Section 2.02. Form of Trustee’s Certificate of Authentication.

          The Trustee’s certificate of authentication on all Debt Securities shall be in
substantially the following form:

          This certificate represents Debt Securities referred to in the within-mentioned Indenture.

          WILMINGTON TRUST COMPANY, not in its individual capacity but solely as trustee

	 	 	 	 	 	 	 
	 

	 	 By	 	 	 	 
	 

	 	 	 	 

Authorized Officer
	 	 

          Section 2.03. Form and Denomination of Debt Securities.

          The Debt Securities shall be substantially in the form of Exhibit A hereto. The Debt
Securities shall be in registered, certificated form without coupons and in minimum denominations
of $100,000 and any multiple of $1,000 in excess thereof. The Debt Securities

9

 

shall be numbered, lettered, or otherwise distinguished in such manner or in accordance with such
plans as the officers executing the same may determine with the approval of the Trustee as
evidenced by the execution and authentication thereof.

          Section 2.04. Execution of Debt Securities.

          The Debt Securities shall be signed in the name and on behalf of the Company by the manual or
facsimile signature of its Chairman of the Board of Directors, Vice Chairman, President or Chief
Financial Officer or one of its Executive Vice Presidents, Senior Vice Presidents, Vice Presidents
or any other officer authorized by the Board of Directors to sign documents in the name and on
behalf of the Company, under its corporate seal (if then legally required) which may be affixed
thereto or printed, engraved or otherwise reproduced thereon, by facsimile or otherwise, and which
need not be attested. Only such Debt Securities as shall bear thereon a certificate of
authentication substantially in the form herein before recited, executed by the Trustee or the
Authenticating Agent by the manual signature of an authorized officer, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the
Trustee or the Authenticating Agent upon any Debt Security executed by the Company shall be
conclusive evidence that the Debt Security so authenticated has been duly authenticated and
delivered hereunder and that the holder is entitled to the benefits of this Indenture.

          In case any officer of the Company who shall have signed any of the Debt Securities shall
cease to be such officer before the Debt Securities so signed shall have been authenticated and
delivered by the Trustee or the Authenticating Agent, or disposed of by the Company, such Debt
Securities nevertheless may be authenticated and delivered or disposed of as though the Person who
signed such Debt Securities had not ceased to be such officer of the Company; and any Debt Security
may be signed on behalf of the Company by such Persons as, at the actual date of the execution of
such Debt Security, shall be the proper officers of the Company, although at the date of the
execution of this Indenture any such person was not such an officer.

          Every Debt Security shall be dated the date of its authentication.

          Section 2.05. Exchange and Registration of Transfer of Debt Securities.

          The Company shall cause to be kept, at the office or agency maintained for the purpose of
registration of transfer and for exchange as provided in Section 3.02, a register (the “Debt
Security Register”) for the Debt Securities issued hereunder in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration and transfer of all
Debt Securities as provided in this Article II. Such register shall be in written form or in any
other form capable of being converted into written form within a reasonable time.

          Debt Securities to be exchanged may be surrendered at the Principal Office of the Trustee or
at any office or agency to be maintained by the Company for such purpose as provided in Section
3.02, and the Company shall execute, the Company or the Trustee shall register and the Trustee or
the Authenticating Agent shall authenticate and make available for delivery in exchange therefor
the Debt Security or Debt Securities which the Securityholder

10

 

making the exchange shall be entitled to receive. Upon due presentment for registration of transfer
of any Debt Security at the Principal Office of the Trustee or at any office or agency of the
Company maintained for such purpose as provided in Section 3.02, the Company shall execute, the
Company or the Trustee shall register and the Trustee or the Authenticating Agent shall
authenticate and make available for delivery in the name of the transferee or transferees a new
Debt Security for a like aggregate principal amount. Registration or registration of transfer of
any Debt Security by the Trustee or by any agent of the Company appointed pursuant to Section 3.02,
and delivery of such Debt Security, shall be deemed to complete the registration or registration of
transfer of such Debt Security.

          All Debt Securities presented for registration of transfer or for exchange or payment shall
(if so required by the Company or the Trustee or the Authenticating Agent) be duly endorsed by, or
be accompanied by, a written instrument or instruments of transfer in form satisfactory to the
Company and either the Trustee or the Authenticating Agent duly executed by, the holder or such
holder’s attorney duly authorized in writing.

          No service charge shall be made for any exchange or registration of transfer of Debt
Securities, but the Company or the Trustee may require payment of a sum sufficient to cover any
tax, fee or other governmental charge that may be imposed in connection therewith.

          The Company or the Trustee shall not be required to exchange or register a transfer of any
Debt Security for a period of 15 days immediately preceding the date of selection of Debt
Securities for redemption.

          Notwithstanding the foregoing, Debt Securities may not be transferred except in compliance
with the restricted securities legend set forth below, unless otherwise determined by the Company
in accordance with applicable law, which legend shall be placed on each Debt Security:

          THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR ANY STATE SECURITIES LAWS OR ANY OTHER APPLICABLE SECURITIES LAWS. NEITHER
THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED,
TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR
UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE

OTHERWISE TRANSFER SUCH SECURITY ONLY (A) TO THE COMPANY, (B) PURSUANT TO RULE 144A UNDER THE
SECURITIES ACT (“RULE 144A”), TO A PERSON THE HOLDER REASONABLY BELIEVES IS A “QUALIFIED
INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT
OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN
RELIANCE ON RULE 144A, (C) PURSUANT TO AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT TO AN “ACCREDITED INVESTOR” WITHIN THE MEANING OF SUBPARAGRAPH (a) (1), (2), (3) OR
(7) OF RULE 501 UNDER THE SECURITIES ACT THAT IS ACQUIRING

11

 

THE SECURITY FOR ITS OWN ACCOUNT, OR FOR THE ACCOUNT OF AN “ACCREDITED INVESTOR,” FOR INVESTMENT
PURPOSES AND NOT WITH A VIEW TO, OR FOR OFFER OR SALE IN CONNECTION WITH, ANY DISTRIBUTION IN
VIOLATION OF THE SECURITIES ACT, OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S RIGHT PRIOR TO ANY SUCH
OFFER, SALE OR TRANSFER PURSUANT TO CLAUSES (C) OR (D) TO REQUIRE THE DELIVERY OF AN OPINION OF
COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO IT IN ACCORDANCE WITH THE
INDENTURE, A COPY OF WHICH MAY BE OBTAINED FROM THE COMPANY. THE HOLDER OF THIS SECURITY BY ITS
ACCEPTANCE HEREOF AGREES THAT IT WILL COMPLY WITH THE FOREGOING RESTRICTIONS.

          THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES, REPRESENTS AND WARRANTS THAT IT
WILL NOT ENGAGE IN HEDGING TRANSACTIONS INVOLVING THIS SECURITY UNLESS SUCH TRANSACTIONS ARE IN
COMPLIANCE WITH THE SECURITIES ACT.

          THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF ALSO AGREES, REPRESENTS AND WARRANTS THAT
IT IS NOT AN EMPLOYEE BENEFIT, INDIVIDUAL RETIREMENT ACCOUNT OR OTHER PLAN OR ARRANGEMENT SUBJECT
TO TITLE I OF THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED (“ERISA”), OR SECTION
4975 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”), (EACH A “PLAN”), OR AN ENTITY
WHOSE UNDERLYING ASSETS INCLUDE “PLAN ASSETS” BY REASON OF ANY PLAN’S INVESTMENT IN THE ENTITY AND
NO PERSON INVESTING “PLAN ASSETS” OF ANY PLAN MAY ACQUIRE OR HOLD THIS SECURITY OR ANY INTEREST
THEREIN, UNLESS SUCH PURCHASER OR HOLDER IS ELIGIBLE FOR THE EXEMPTIVE RELIEF AVAILABLE UNDER U.S.
DEPARTMENT OF LABOR PROHIBITED TRANSACTION CLASS EXEMPTION 96-23, 95-60, 91-38, 90-1 OR 84-14 OR
ANOTHER APPLICABLE EXEMPTION OR ITS PURCHASE AND HOLDING OF THIS SECURITY IS NOT PROHIBITED BY
SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE WITH RESPECT TO SUCH PURCHASE OR HOLDING. ANY
PURCHASER OR HOLDER OF THIS SECURITY OR ANY INTEREST THEREIN WILL BE DEEMED TO HAVE REPRESENTED BY
ITS PURCHASE AND HOLDING THEREOF THAT EITHER (i) IT IS NOT AN EMPLOYEE BENEFIT PLAN WITHIN THE
MEANING OF SECTION 3(3) OF ERISA, OR A PLAN TO WHICH SECTION 4975 OF THE CODE IS APPLICABLE, A
TRUSTEE OR OTHER PERSON ACTING ON BEHALF OF AN EMPLOYEE BENEFIT PLAN OR PLAN, OR ANY OTHER PERSON
OR ENTITY USING THE ASSETS OF ANY EMPLOYEE BENEFIT PLAN OR PLAN TO FINANCE SUCH PURCHASE, OR (ii)
SUCH PURCHASE WILL NOT RESULT IN A PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION
4975 OF THE CODE FOR WHICH THERE IS NO APPLICABLE STATUTORY OR ADMINISTRATIVE EXEMPTION.

          IN CONNECTION WITH ANY TRANSFER, THE HOLDER OF THIS SECURITY WILL DELIVER TO THE
REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS MAY BE REQUIRED BY THE

12

 

INDENTURE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

          THIS SECURITY WILL BE ISSUED AND MAY BE TRANSFERRED ONLY IN BLOCKS HAVING A PRINCIPAL AMOUNT
OF NOT LESS THAN $100,000 AND MULTIPLES OF $1,000 IN EXCESS THEREOF. ANY ATTEMPTED TRANSFER OF THIS
SECURITY IN A BLOCK HAVING A PRINCIPAL AMOUNT OF LESS THAN $100,000 SHALL BE DEEMED TO BE VOID AND
OF NO LEGAL EFFECT WHATSOEVER. ANY SUCH PURPORTED TRANSFEREE SHALL BE DEEMED NOT TO BE THE HOLDER
OF THIS SECURITY FOR ANY PURPOSE, INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF DISTRIBUTIONS ON
THIS SECURITY, AND SUCH PURPORTED TRANSFEREE SHALL BE DEEMED TO HAVE NO INTEREST WHATSOEVER IN THIS
SECURITY.

          THIS OBLIGATION IS NOT A DEPOSIT AND IS NOT INSURED BY THE UNITED STATES OR ANY AGENCY OR FUND
OF THE UNITED STATES, INCLUDING THE FEDERAL DEPOSIT INSURANCE CORPORATION. THIS OBLIGATION IS
SUBORDINATED TO THE CLAIMS OF DEPOSITORS AND THE CLAIMS OF GENERAL AND SECURED CREDITORS OF THE
COMPANY, IS INELIGIBLE AS COLLATERAL FOR A LOAN BY THE COMPANY OR ANY OF ITS SUBSIDIARIES AND IS
NOT SECURED.

          Section 2.06. Mutilated, Destroyed, Lost or Stolen Debt Securities.

          In case any Debt Security shall become mutilated or be destroyed, lost or stolen, the Company
shall execute, and upon its written request the Trustee shall authenticate and deliver, a new Debt
Security bearing a number not contemporaneously outstanding, in exchange and substitution for the
mutilated Debt Security, or in lieu of and in substitution for the Debt Security so destroyed, lost
or stolen. In every case the applicant for a substituted Debt Security shall furnish to the Company
and the Trustee such security or indemnity as may be required by them to save each of them
harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the
Company and the Trustee evidence to their satisfaction of the destruction, loss or theft of such
Debt Security and of the ownership thereof.

          The Trustee may authenticate any such substituted Debt Security and deliver the same upon the
written request or authorization of any officer of the Company. Upon the issuance of any
substituted Debt Security, 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
connected therewith. In case any Debt Security which has matured or is about to mature or has been
called for redemption in full shall become mutilated or be destroyed, lost or stolen, the Company
may, instead of issuing a substitute Debt Security, pay or authorize the payment of the same
(without surrender thereof except in the case of a mutilated Debt Security) if the applicant for
such payment shall furnish to the Company and the Trustee such security or indemnity as may be
required by them to save each of them harmless and, in case of destruction, loss or theft, evidence
satisfactory to the Company and to the Trustee of the destruction, loss or theft of such Security
and of the ownership thereof.

13

 

          Every substituted Debt Security issued pursuant to the provisions of this Section 2.06 by
virtue of the fact that any such Debt Security is destroyed, lost or stolen shall constitute an
additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debt
Security shall be found at any time, and shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Debt Securities duly issued hereunder. All Debt
Securities shall be held and owned upon the express condition that, to the extent permitted by
applicable law, the foregoing provisions are exclusive with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Debt Securities and shall preclude any and all other rights
or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with
respect to the replacement or payment of negotiable instruments or other securities without their
surrender.

          Section 2.07. Temporary Debt Securities.

          Pending the preparation of definitive Debt Securities, the Company may execute and the Trustee
shall authenticate and make available for delivery temporary Debt Securities that are typed,
printed or lithographed. Temporary Debt Securities shall be issuable in any authorized
denomination, and substantially in the form of the definitive Debt Securities but with such
omissions, insertions and variations as may be appropriate for temporary Debt Securities, all as
may be determined by the Company. Every such temporary Debt Security shall be executed by the
Company and be authenticated by the Trustee upon the same conditions and in substantially the same
manner, and with the same effect, as the definitive Debt Securities. Without unreasonable delay,
the Company will execute and deliver to the Trustee or the Authenticating Agent definitive Debt
Securities and thereupon any or all temporary Debt Securities may be surrendered in exchange
therefor, at the Principal Office of the Trustee or at any office or agency maintained by the
Company for such purpose as provided in Section 3.02, and the Trustee or the Authenticating Agent
shall authenticate and make available for delivery in exchange for such temporary Debt Securities a
like aggregate principal amount of such definitive Debt Securities. Such exchange shall be made by
the Company at its own expense and without any charge therefor except that in case of any such
exchange involving a registration of transfer the Company may require payment of a sum sufficient
to cover any tax, fee or other governmental charge that may be imposed in relation thereto. Until
so exchanged, the temporary Debt Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Debt Securities authenticated and delivered hereunder.

          Section 2.08. Payment of Interest.

          Each Debt Security will bear interest at the then applicable Interest Rate from and including
each Interest Payment Date or, in the case of the first interest period, the original date of
issuance of such Debt Security to, but excluding, the next succeeding Interest Payment Date or, in
the case of the last interest period, the Redemption Date, Special Redemption Date or Maturity
Date, as applicable (each such period, an “Interest Period”), on the principal thereof, on any
overdue principal and (to the extent that payment of such interest is enforceable under applicable
law) on Deferred Interest and on any overdue installment of interest (including Defaulted
Interest), payable (subject to the provisions of Article XII) on each Interest Payment Date
commencing on September 23, 2006, and on the Redemption Date, the Special Redemption Date or the
Maturity Date, as the case may be. Interest and any Deferred Interest on any Debt

14

 

Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date
shall be paid to the Person in whose name such Debt Security (or one or more Predecessor
Securities) is registered at the close of business on the regular record date for such interest
installment, except that interest and any Deferred Interest payable on the Maturity Date, the
Redemption Date or the Special Redemption Date, as the case may be, shall be paid to the Person to
whom principal is paid. In the event that any Debt Security or portion thereof is called for
redemption and the redemption date is subsequent to a regular record date with respect to any
Interest Payment Date and prior to such Interest Payment Date, interest on such Debt Security will
be paid upon presentation and surrender of such Debt Security.

          Any interest on any Debt Security, other than Deferred Interest, that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted
Interest”) shall forthwith cease to be payable to the registered holder on the relevant regular
record date by virtue of having been such holder, and such Defaulted Interest shall be paid by the
Company to the Persons in whose names such Debt Securities (or their respective Predecessor
Securities) are registered at the close of business on a special record date for the payment of
such Defaulted Interest, which shall be fixed in the following manner: the Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Debt
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 prior to
the date of the proposed payment, such money when deposited to be held in trust for the benefit of
the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee
shall fix a special record date for the payment of such Defaulted Interest which shall not be more
than fifteen nor less than ten days prior to the date of the proposed payment and not less than ten
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 each Securityholder at his or
her address as it appears in the Debt Security Register, not less than ten days prior to 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
Persons in whose names such Debt Securities (or their respective Predecessor Securities) are
registered on such special record date and thereafter the Company shall have no further payment
obligation in respect of the Defaulted Interest.

          Any interest scheduled to become payable on an Interest Payment Date occurring during an
Extension Period shall not be Defaulted Interest and shall be payable on such other date as may be
specified in the terms of such Debt Securities.

          The term “regular record date” as used in this Section shall mean the fifteenth day prior to
the applicable Interest Payment Date whether or not such date is a Business Day.

          Subject to the foregoing provisions of this Section, each Debt Security delivered under this
Indenture upon registration of transfer of or in exchange for or in lieu of any other

15

 

Debt Security shall carry the rights to interest accrued and unpaid, and to accrue, that were
carried by such other Debt Security.

          Section 2.09. Cancellation of Debt Securities Paid, etc.

          All Debt Securities surrendered for the purpose of payment, redemption, exchange or
registration of transfer, shall, if surrendered to the Company or any Paying Agent, be surrendered
to the Trustee and promptly canceled by it, or, if surrendered to the Trustee or any Authenticating
Agent, shall be promptly canceled by it, and no Debt Securities shall be issued in lieu thereof
except as expressly permitted by any of the provisions of this Indenture. All Debt Securities
canceled by any Authenticating Agent shall be delivered to the Trustee. The Trustee shall destroy
all canceled Debt Securities unless the Company otherwise directs the Trustee in writing, in which
case the Trustee shall dispose of such Debt Securities as directed by the Company. If the Company
shall acquire any of the Debt Securities, however, such acquisition shall not operate as a
redemption or satisfaction of the indebtedness represented by such Debt Securities unless and until
the same are surrendered to the Trustee for cancellation.

          Section 2.10. Computation of Interest.

          (a) The amount of interest payable for each Interest Period during the Fixed Period will be
computed on the basis of a 360-day year and twelve 30-day months and, thereafter, on the basis of a
360-day year and the actual number of days elapsed in such Interest Period; provided,
however, that upon the occurrence of a Special Event redemption pursuant to Section 10.02
the amounts payable pursuant to this Indenture shall be calculated as set forth in the definition
of Special Redemption Price.

          (b) LIBOR shall be determined by the Calculation Agent for each Interest Period after the end
of the Interest Period with respect to the Interest Payment Date occurring in September 2011 (the
“Fixed Period”) in accordance with the following provisions:

     (1) On the second LIBOR Business Day (provided, that on such day
commercial banks are open for business (including dealings in foreign currency
deposits) in London (a “LIBOR Banking Day”), and otherwise the next preceding LIBOR
Business Day that is also a LIBOR Banking Day) prior to March 23, June 23, September
23 and December 23, as the case may be, immediately preceding the commencement of
such Interest Period, (each such day, a “LIBOR Determination Date”), LIBOR shall
equal the rate, as obtained by the Calculation Agent for three-month U.S. Dollar
deposits in Europe, which appears on Telerate (as defined in the International Swaps
and Derivatives Association, Inc. 2000 Interest Rate and Currency Exchange
Definitions) Page 3750 or such other page as may replace such Telerate Page 3750, as
of 11:00 a.m. (London time) on such LIBOR Determination Date, as reported by
Bloomberg Financial Markets Commodities News (or any successor service). “LIBOR
Business Day” means any day that is not a Saturday, Sunday or other day on which
commercial banking institutions in New York, New York or Wilmington, Delaware are
authorized or obligated by law or executive order to be closed. If such rate is
superseded on Telerate Page 3750 by a corrected rate before 12:00 noon (London time)
on the

16

 

same LIBOR Determination Date, the corrected rate as so substituted will be the
applicable LIBOR for that LIBOR Determination Date.

     (2) If, on any LIBOR Determination Date, such rate does not appear on Telerate
Page 3750 as reported by Bloomberg Financial Markets Commodities News or such other
page as may replace such Telerate Page 3750, the Calculation Agent shall determine
the arithmetic mean of the offered quotations of the Reference Banks (as defined
below) to leading banks in the London interbank market for three-month U.S. Dollar
deposits in Europe (in an amount determined by the Calculation Agent) by reference
to requests for quotations as of approximately 11:00 a.m. (London time) on the LIBOR
Determination Date made by the Calculation Agent to the Reference Banks. If, on any
LIBOR Determination Date, at least two of the Reference Banks provide such
quotations, LIBOR shall equal the arithmetic mean of such quotations. If, on any
LIBOR Determination Date, only one or none of the Reference Banks provide such a
quotation, LIBOR shall be deemed to be the arithmetic mean of the offered quotations
that at least two leading banks in the City of New York (as selected by the
Calculation Agent) are quoting on the relevant LIBOR Determination Date for
three-month U.S. Dollar deposits in Europe at approximately 11:00 a.m. (London time)
(in an amount determined by the Calculation Agent). As used herein, “Reference
Banks” means four major banks in the London interbank market selected by the
Calculation Agent.

     (3) If the Calculation Agent is required but is unable to determine a rate in
accordance with at least one of the procedures provided above, LIBOR shall be LIBOR
in effect on the previous LIBOR Determination Date (whether or not LIBOR for such
period was in fact determined on such LIBOR Determination Date).

          (c) All percentages resulting from any calculations on the Debt Securities will be rounded, if
necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of
a percentage point rounded upward (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or
..0987655)), and all dollar amounts used in or resulting from such calculation will be rounded to
the nearest cent (with one-half cent being rounded upward).

          (d) On each LIBOR Determination Date, the Calculation Agent shall notify, in writing, the
Company and the Paying Agent of the applicable Interest Rate in effect for the related Interest
Period. The Calculation Agent shall, upon the request of the holder of any Debt Securities, provide
the Interest Rate then in effect. All calculations made by the Calculation Agent in the absence of
manifest error shall be conclusive for all purposes and binding on the Company and the holders of
the Debt Securities. The Paying Agent shall be entitled to rely on information received from the
Calculation Agent or the Company as to the Interest Rate. The Company shall, from time to time,
provide any necessary information to the Paying Agent relating to any original issue discount and
interest on the Debt Securities that is included in any payment and reportable for taxable income
calculation purposes.

          Section 2.11. Extension of Interest Payment Period.

          So long as no Event of Default pursuant to Sections 5.01(b), (e) or (f) of this Indenture has
occurred and is continuing, the Company shall have the right, from time to time and without causing
an Event of Default, to defer payments of interest on the Debt Securities by extending the interest
payment period on the Debt Securities at any time and from time to time during the term of the Debt
Securities, for up to twenty consecutive quarterly periods (each such extended interest payment
period, an “Extension Period”). No Extension Period may end on a date other than an Interest
Payment Date. During any Extension Period, interest will continue to accrue on the Debt Securities,
and interest on such accrued interest (such accrued interest and interest thereon referred to
herein as “Deferred Interest”) will accrue, at the Interest Rate, compounded quarterly from the
date such Deferred Interest would have been payable were it not for the Extension Period, both to
the extent permitted by law. No interest or Deferred Interest (except any Additional Interest that
may be due and payable) shall be due and payable during an Extension Period, except at the end
thereof. At the end of any such Extension Period the Company shall pay all Deferred Interest then
accrued and unpaid on the Debt Securities; provided, however, that no Extension
Period may extend beyond the Maturity Date, Redemption Date or Special Redemption Date; and
provided further, however, that during any such Extension Period, the Company shall
be subject to the restrictions set forth in Section 3.08 of this Indenture. Prior to the
termination of any Extension Period, the Company may further extend such period, provided,
that such period together with all such previous and further consecutive extensions thereof shall
not exceed twenty consecutive quarterly periods. Upon the termination of any Extension Period and
upon the payment of all Deferred Interest, the Company may commence a new Extension Period, subject
to the foregoing requirements. The Company must give the Trustee notice of its election to begin
such Extension Period at least one Business Day prior to the date such interest is payable, but in
any event not later than the related regular record date. The Trustee shall give notice of the
Company’s election to begin a new Extension Period to the Securityholders.

          Section 2.12. CUSIP Numbers.

          The Company in issuing the Debt Securities may use “CUSIP” numbers (if then generally in use),
and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to
Securityholders; provided, that any such notice may state that no representation is made as
to the correctness of such numbers either as printed on the Debt 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 Debt 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 in writing of any change in
the CUSIP numbers.

ARTICLE III

PARTICULAR COVENANTS OF THE COMPANY

          Section 3.01. Payment of Principal, Premium and Interest; Agreed Treatment of the Debt
Securities.

          (a) The Company covenants and agrees that it will duly and punctually pay or cause to be paid
all payments due on the Debt Securities at the place, at the respective times and in the manner
provided in this Indenture and the Debt Securities. At the option of the Company, each installment
of interest on the Debt Securities may be paid (i) by mailing checks for such interest payable to
the order of the holders of Debt Securities entitled thereto as they appear on the Debt Security
Register or (ii) by wire transfer to any account with a banking institution located in the United
States designated by such Person to the Paying Agent no later than the related record date.

          (b) The Company will treat the Debt Securities as indebtedness, and the interest payable in
respect of such Debt Securities as interest, for all U.S. federal income tax purposes. All payments
in respect of such Debt Securities will be made free and clear of U.S. withholding tax to any
beneficial owner thereof that has provided an Internal Revenue Service Form W-8BEN (or any
substitute or successor form) establishing its non-U.S. status for U.S. federal income tax
purposes.

          (c) As of the date of this Indenture, the Company has no intention to exercise its right
under Section 2.11 to defer payments of interest on the Debt Securities by commencing an Extension
Period.

          (d) As of the date of this Indenture, the Company represents that the likelihood that it would
exercise its right under Section 2.11 to defer payments of interest on the Debt Securities by
commencing an Extension Period at any time during which the Debt Securities are outstanding is
remote because of the restrictions that would be imposed on the Company’s ability to declare or pay
dividends or distributions on, or to redeem, purchase or make a liquidation payment with respect
to, any of its outstanding equity and on the Company’s ability to make any payments of principal of
or premium, if any, or interest on, or repurchase or redeem, any of its debt securities that rank
pari passu in all respects with (or junior in interest to) the Debt Securities.

          Section 3.02. Offices for Notices and Payments, etc.

          So long as any of the Debt Securities remain outstanding, the Company will maintain in
Wilmington, Delaware or in Quincy, Illinois an office or agency where the Debt Securities may be
presented for payment, an office or agency where the Debt Securities may be presented for
registration of transfer and for exchange as provided in this Indenture and an office or agency
where notices and demands to or upon the Company in respect of the Debt Securities or of this
Indenture may be served. The Company will give to the Trustee written notice of the location of any
such office or agency and of any change of location thereof. Until otherwise designated from time
to time by the Company in a notice to the Trustee, or specified as

19

 

contemplated by Section 2.05, such office or agency for all of the above purposes shall be the
Principal Office of the Trustee. In case the Company shall fail to maintain any such office or
agency in Wilmington, Delaware or in Quincy, Illinois or shall fail to give such notice of the
location or of any change in the location thereof, presentations and demands may be made and
notices may be served at the Principal Office of the Trustee.

          In addition to any such office or agency, the Company may from time to time designate one or
more offices or agencies outside Wilmington, Delaware or Quincy, Illinois where the Debt Securities
may be presented for registration of transfer and for exchange in the manner provided in this
Indenture, and the Company may from time to time rescind such designation, as the Company may deem
desirable or expedient; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain any such office or agency in
Wilmington, Delaware or in Quincy, Illinois for the purposes above mentioned. The Company will give
to the Trustee prompt written notice of any such designation or rescission thereof.

          Section 3.03. Appointments to Fill Vacancies in Trustee’s Office.

          The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will
appoint, in the manner provided in Section 6.09, a Trustee, so that there shall at all times be a
Trustee hereunder.

          Section 3.04. Provision as to Paying Agent.

          (a) If the Company shall appoint a Paying Agent other than the Trustee, it will
cause such Paying Agent to execute and deliver to the Trustee an instrument in which such
agent
shall agree with the Trustee, subject to the provision of this Section 3.04,

     (1) that it will hold all sums held by it as such agent for the payment of all
payments due on the Debt Securities (whether such sums have been paid to it by the
Company or by any other obligor on the Debt Securities) in trust for the benefit of
the holders of the Debt Securities;

     (2) that it will give the Trustee prompt written notice of any failure by the
Company (or by any other obligor on the Debt Securities) to make any payment on the
Debt Securities when the same shall be due and payable; and

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

          (b) If the Company shall act as its own Paying Agent, it will, on or before
each due date of the payments due on the Debt Securities, set aside, segregate and hold in
trust
for the benefit of the holders of the Debt Securities a sum sufficient to pay such principal,
premium or interest so becoming due and will notify the Trustee in writing of any failure to
take
such action and of any failure by the Company (or by any other obligor under the Debt
Securities) to make any payment on the Debt Securities when the same shall become due and
payable.

20

 

          Whenever the Company shall have one or more Paying Agents for the Debt Securities, it will, on
or prior to each due date of the payments on the Debt Securities, deposit with a Paying Agent a sum
sufficient to pay all payments 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 shall promptly
notify the Trustee in writing of its action or failure to act.

          (c) Anything in this Section 3.04 to the contrary notwithstanding, the Company may, at any
time, for the purpose of obtaining a satisfaction and discharge with respect to the Debt
Securities, or for any other reason, pay, or direct any Paying Agent to pay to the Trustee all sums
held in trust by the Company or any such Paying Agent, such sums to be held by the Trustee upon the
same terms and conditions herein contained.

          (d) Anything in this Section 3.04 to the contrary notwithstanding, the agreement to hold sums
in trust as provided in this Section 3.04 is subject to Sections 12.03 and 12.04.

          (e) The Company hereby initially appoints the Trustee to act as Paying Agent.

          Section 3.05. Certificate to Trustee.

          The Company will deliver to the Trustee on or before 120 days after the end of each fiscal
year, so long as Debt Securities are outstanding hereunder, a Certificate, substantially in the
form of Exhibit B attached hereto, stating that in the course of the performance by the signers of
their duties as officers of the Company they would normally have knowledge of any default by the
Company in the performance of any covenants contained herein, stating whether or not they have
knowledge of any such default and, if so, specifying each such default of which the signers have
knowledge and the nature thereof.

          Section 3.06. Additional Interest.

          If and for so long as the Trust is the holder of all Debt Securities and is subject to, or
otherwise required to pay, or is required to withhold from distributions to holders of Trust
Securities, any additional taxes (including withholding taxes), duties, assessments or other
governmental charges as a result of a Tax Event, the Company will pay such additional amounts (the
“Additional Interest”) on the Debt Securities as shall be required so that the net amounts received
and retained by the Trust after paying taxes, duties, assessments or other governmental charges
will be equal to the amounts the Trust would have received if no such taxes, duties, assessments or
other governmental charges had been imposed. Whenever in this Indenture or the Debt Securities
there is a reference in any context to the payment of principal of or premium, if any, or interest
on the Debt Securities, such mention shall be deemed to include mention of payments of the
Additional Interest provided for in this paragraph to the extent that, in such context, Additional
Interest is, was or would be payable in respect thereof pursuant to the provisions of this
paragraph and express mention of the payment of Additional Interest (if applicable) in any
provisions hereof shall not be construed as excluding Additional Interest in those provisions
hereof where such express mention is not made, provided, however, that the deferral
of the payment of interest during an Extension Period pursuant to Section 2.11 shall not defer the
payment of any Additional Interest that may be due and payable.

21

 

          Section 3.07. Compliance with Consolidation Provisions.

          The Company will not, while any of the Debt Securities remain outstanding, consolidate with,
or merge into any other Person, or merge into itself, or sell or convey all or substantially all of
its property to any other Person unless the provisions of Article XI hereof are complied with.

          Section 3.08. Limitation on Dividends.

          If (i) there shall have occurred and be continuing a Default or an Event of Default, (ii) the
Company shall be in default with respect to its payment of any obligations under the Capital
Securities Guarantee or (iii) the Company shall have given notice of its election to defer payments
of interest on the Debt Securities by extending the interest payment period as provided herein and
such period, or any extension thereof, shall have commenced and be continuing, then the Company may
not (A) declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Company’s capital stock, (B) make any payment of
principal of or interest or premium, if any, on or repay, repurchase or redeem any debt securities
of the Company that rank pari passu in all respects with or junior in interest to the Debt
Securities or (C) make any payment under any guarantees of the Company that rank pari passu in all
respects with or junior in interest to the Capital Securities Guarantee (other than (a)
repurchases, redemptions or other acquisitions of shares of capital stock of the Company (I) in
connection with any employment contract, benefit plan or other similar arrangement with or for the
benefit of one or more employees, officers, directors or consultants, (II) in connection with a
dividend reinvestment or stockholder stock purchase plan or (III) in connection with the issuance
of capital stock of the Company (or securities convertible into or exercisable for such capital
stock) as consideration in an acquisition transaction entered into prior to the occurrence of (i),
(ii) or (iii) above, (b) as a result of any exchange or conversion of any class or series of the
Company’s capital stock (or any capital stock of a subsidiary of the Company) for any class or
series of the Company’s capital stock or of any class or series of the Company’s indebtedness for
any class or series of the Company’s capital stock, (c) the purchase of fractional interests in
shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such
capital stock or the security being converted or exchanged, (d) any declaration of a dividend in
connection with any stockholder’s rights plan, or the issuance of rights, stock or other property
under any stockholder’s rights plan, or the redemption or repurchase of rights pursuant thereto or
(e) any dividend in the form of stock, warrants, options or other rights where the dividend stock
or the stock issuable upon exercise of such warrants, options or other rights is the same stock as
that on which the dividend is being paid or ranks pari passu with or junior in interest to such
stock).

          Section 3.09. Covenants as to the Trust.

          For so long as such Trust Securities remain outstanding, the Company shall maintain 100%
ownership of the Common Securities; provided, however, that any permitted successor
of the Company under this Indenture that is a U.S. Person may succeed to the Company’s ownership of
such Common Securities. The Company, as owner of the Common Securities, shall use commercially
reasonable efforts to cause the Trust (a) to remain a statutory trust, except in connection with a
distribution of Debt Securities to the holders of Trust Securities

22

 

in liquidation of the Trust, the redemption of all of the Trust Securities or certain mergers,
consolidations or amalgamations, each as permitted by the Declaration, (b) to otherwise continue to
be classified as a grantor trust for United States federal income tax purposes and (c) to cause
each holder of Trust Securities to be treated as owning an undivided beneficial interest in the
Debt Securities.

ARTICLE IV 

LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

          Section 4.01. Securityholders’ Lists.

          The Company covenants and agrees that it will furnish or cause to be furnished to the Trustee:

          (a) on each regular record date for an Interest Payment Date, a list, in such form as the
Trustee may reasonably require, of the names and addresses of the Securityholders of the Debt
Securities as of such record date; and

          (b) at such other times as the Trustee may request in writing, within 30 days after the
receipt by the Company of any such request, a list of similar form and content as of a date not
more than 15 days prior to the time such list is furnished;

except that no such lists need be furnished under this Section 4.01 so long as the Trustee is in
possession thereof by reason of its acting as Debt Security registrar.

          Section 4.02. Preservation and Disclosure of Lists.

          (a) The Trustee shall preserve, in as current a form as is reasonably practicable, all
information as to the names and addresses of the holders of Debt Securities (1) contained in the
most recent list furnished to it as provided in Section 4.01 or (2) received by it in the capacity
of Debt Securities registrar (if so acting) hereunder. The Trustee may destroy any list furnished
to it as provided in Section 4.01 upon receipt of a new list so furnished.

          (b) In case three or more holders of Debt Securities (hereinafter referred to as “applicants”)
apply in writing to the Trustee and furnish to the Trustee reasonable proof that each such
applicant has owned a Debt Security for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to communicate with other
holders of Debt Securities with respect to their rights under this Indenture or under such Debt
Securities and is accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall within five Business Days after the receipt
of such application, at its election, either:

          (1) afford such applicants access to the information preserved at the time by the
Trustee in accordance with the provisions of subsection (a) of this Section 4.02, or

23

 

          (2) inform such applicants as to the approximate number of holders of Debt
Securities whose names and addresses appear in the information preserved at the time by the
Trustee in accordance with the provisions of subsection (a) of this Section 4.02, and as to
the approximate cost of mailing to such Securityholders the form of proxy or other
communication, if any, specified in such application.

     If the Trustee shall elect not to afford such applicants access to such information, the
Trustee shall, upon the written request of such applicants, mail to each Securityholder of Debt
Securities whose name and address appear in the information preserved at the time by the Trustee in
accordance with the provisions of subsection (a) of this Section 4.02 a copy of the form of proxy
or other communication which is specified in such request with reasonable promptness after a tender
to the Trustee of the material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless within five days after such tender, the Trustee shall mail
to such applicants and file with the Securities and Exchange Commission, if permitted or required
by applicable law, together with a copy of the material to be mailed, a written statement to the
effect that, in the opinion of the Trustee, such mailing would be contrary to the best interests of
the holders of all Debt Securities, as the case may be, or would be in violation of applicable law.
Such written statement shall specify the basis of such opinion. If said Commission, as permitted or
required by applicable law, after opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to sustain any of such objections or if,
after the entry of an order sustaining one or more of such objections, said Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained have been met and
shall enter an order so declaring, the Trustee shall mail copies of such material to all such
Securityholders with reasonable promptness after the entry of such order and the renewal of such
tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

          (c) Each and every holder of Debt Securities, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor any Paying Agent
shall be held accountable by reason of the disclosure of any such information as to the names and
addresses of the holders of Debt Securities in accordance with the provisions of subsection (b) of
this Section 4.02, regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant to a request made
under said subsection (b).

          Section 4.03. Financial and Other Information.

          (a) The Company shall deliver to each holder of the Debt Securities and the Capital
Securities (1) if the Company or any of its Subsidiaries is not then (x) subject to Section 13 or
15(d) of the Exchange Act or (y) exempt from reporting pursuant to Rule 12g3-2(b) thereunder, the
information required by Rule 144A(d)(4) under the Securities Act, (2) if the Company is not then
required to file Form FR Y-9C, the audited annual financial statements (or, if no audited financial
statements are prepared, the unaudited financial statements) of the Company and any Subsidiaries
within 90 days after the end of the fiscal year, and (3) within 30 days after the end of the fiscal
year of the Company, Form 1099 or such other annual U.S. federal income tax information statement
required by the Code, containing such information with

24

 

regard to the Debt Securities held by such holder as is required by the Code and the income tax
regulations of the U.S. Treasury thereunder.

          (b) If and so long as the holder of the Capital Securities is an entity that holds a
pool of trust preferred securities, debt securities and/or similar securities or a trustee thereof,
the Company will cause copies of its reports on FR Y-9C, FR Y-9LP and FR Y-6 to be delivered to the
holder promptly following their filing with the Federal Reserve.

ARTICLE V

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS UPON AN EVENT OF
DEFAULT

          Section 5.01. Events of Default.

          The following events shall be “Events of Default” with respect to Debt Securities:

          (a) the Company defaults in the payment of any interest upon any Debt Security when it becomes
due and payable, and continuance of such default for a period of 30 days; for the avoidance of
doubt, an extension of any interest payment period by the Company in accordance with Section 2.11
of this Indenture shall not constitute a default under this clause 5.01(a); or

          (b) the Company defaults in the payment of any interest upon any Debt Security, including any
Additional Interest in respect thereof, following the nonpayment of any such interest for twenty
(20) or more consecutive quarterly interest payment periods; or

          (c) the Company defaults in the payment of all or any part of the principal of (or premium, if
any, on) any Debt Securities as and when the same shall become due and payable either at maturity,
upon redemption, by declaration of acceleration or otherwise; or

          (d) the Company defaults in the performance of, or breaches, any of its covenants or
agreements in Sections 3.06, 3.07, 3.08 or 3.09 of this Indenture (other than a covenant or
agreement a default in whose performance or whose breach is elsewhere in this Section specifically
dealt with), and continuance of such default or breach for a period of 90 days after there has been
given, by registered or certified mail, to the Company by the Trustee or to the Company and the
Trustee by the holders of not less than 25% in aggregate principal amount of the outstanding Debt
Securities, a written notice specifying such default or breach and requiring it to be remedied and
stating that such notice is a “Notice of Default” hereunder; or

          (e) a court having jurisdiction in the premises shall enter a decree or order for relief in
respect of the Company in an involuntary case under any applicable bankruptcy, insolvency or other
similar law now or hereafter in effect, or appoints a receiver, liquidator, assignee, custodian,
trustee, sequestrator (or other similar official) of the Company or for any substantial part of its
property, or orders the winding-up or liquidation of its affairs and such decree or order shall
remain unstayed and in effect for a period of 90 consecutive days; or

25

 

          (f) the Company shall commence a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, shall consent to the entry of an order for relief in
an involuntary case under any such law, or shall consent to the appointment of or taking possession
by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official)
of the Company or of any substantial part of its property, or shall make any general assignment for
the benefit of creditors, or shall fail generally to pay its debts as they become due; or

          (g) the Trust shall have voluntarily or involuntarily liquidated, dissolved, wound-up its
business or otherwise terminated its existence except in connection with (1) the distribution of
the Debt Securities to holders of the Trust Securities in liquidation of their interests in the
Trust, (2) the redemption of all of the outstanding Trust Securities or (3) certain mergers,
consolidations or amalgamations, each as permitted by the Declaration.

          If an Event of Default specified under clause (b) of this Section 5.01 occurs and is
continuing with respect to the Debt Securities, then, in each and every such case, either the
Trustee or the holders of not less than 25% in aggregate principal amount of the Debt Securities
then outstanding hereunder, by notice in writing to the Company (and to the Trustee if given by
Securityholders), may declare the entire principal of the Debt Securities and any premium and
interest accrued, but unpaid, thereon to be due and payable immediately, and upon any such
declaration the same shall become immediately due and payable. If an Event of Default specified
under clause (e) or (f) of this Section 5.01 occurs, then, in each and every such case, the entire
principal amount of the Debt Securities and any premium and interest accrued, but unpaid, thereon
shall ipso facto become immediately due and payable without further action.

          The foregoing provisions, however, are subject to the condition that if, at any time after the
principal of the Debt Securities shall have become due by acceleration, and before any judgment or
decree for the payment of the moneys due shall have been obtained or entered as hereinafter
provided, (i) the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all
matured installments of interest upon all the Debt Securities and all payments on the Debt
Securities which shall have become due otherwise than by acceleration (with interest upon all such
payments and Deferred Interest, to the extent permitted by law) and such amount as shall be
sufficient to cover reasonable compensation to the Trustee and each predecessor Trustee, their
respective agents, attorneys and counsel, and all other amounts due to the Trustee pursuant to
Section 6.06, if any, and (ii) all Events of Default under this Indenture, other than the
nonpayment of the payments on Debt Securities which shall have become due by acceleration, shall
have been cured, waived or otherwise remedied as provided herein, then and in every such case the
holders of a majority in aggregate principal amount of the Debt Securities then outstanding, by
written notice to the Company and to the Trustee, may waive all defaults and rescind and annul such
acceleration and its consequences, but no such waiver or rescission and annulment shall extend to
or shall affect any subsequent default or shall impair any right consequent thereon.

          In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of such rescission or annulment or
for any other reason or shall have been determined adversely to the Trustee, then and in every such
case the Company, the Trustee and the holders of the Debt Securities shall be

26

 

restored respectively to their several positions and rights hereunder, and all rights, remedies and
powers of the Company, the Trustee and the holders of the Debt Securities shall continue as though
no such proceeding had been taken.

          Section 5.02. Payment of Debt Securities on Default; Suit Therefor.

          The Company covenants that upon the occurrence of an Event of Default pursuant to clause (b)
of Section 5.01 and upon demand of the Trustee, the Company will pay to the Trustee, for the
benefit of the holders of the Debt Securities, the whole amount that then shall have become due and
payable on all Debt Securities, including Deferred Interest accrued on the Debt Securities; and, in
addition thereto, such further amount as shall be sufficient to cover the costs and expenses of
collection, including a reasonable compensation to the Trustee, its agents, attorneys and counsel,
and any other amounts due to the Trustee under Section 6.06. In case the Company shall fail
forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an
express trust, shall be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any such action or
proceeding to judgment or final decree, and may enforce any such judgment or final decree against
the Company or any other obligor on such Debt Securities and collect in the manner provided by law
out of the property of the Company or any other obligor on such Debt Securities wherever situated
the moneys adjudged or decreed to be payable.

          In case there shall be pending proceedings for the bankruptcy or for the reorganization of the
Company or any other obligor on the Debt Securities under Bankruptcy Law, or in case a receiver or
trustee shall have been appointed for the property of the Company or such other obligor, or in the
case of any other similar judicial proceedings relative to the Company or other obligor upon the
Debt Securities, or to the creditors or property of the Company or such other obligor, the Trustee,
irrespective of whether the principal of the Debt Securities shall then be due and payable as
therein expressed or by acceleration or otherwise and irrespective of whether the Trustee shall
have made any demand pursuant to the provisions of this Section 5.02, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims
for the whole amount of principal and interest owing and unpaid in respect of the Debt Securities
and, in case of any judicial proceedings, to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the Trustee (including
any claim for reasonable compensation to the Trustee and each predecessor Trustee, and their
respective agents, attorneys and counsel, and for reimbursement of all other amounts due to the
Trustee under Section 6.06) and of the Securityholders allowed in such judicial proceedings
relative to the Company or any other obligor on the Debt Securities, or to the creditors or
property of the Company or such other obligor, unless prohibited by applicable law and regulations,
to vote on behalf of the holders of the Debt Securities in any election of a trustee or a standby
trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings
or Person performing similar functions in comparable proceedings, and to collect and receive any
moneys or other property payable or deliverable on any such claims, and to distribute the same
after the deduction of its charges and expenses; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the Securityholders to make such
payments to the Trustee, and, in the event that the Trustee shall consent to the making of such
payments directly to the Securityholders, to pay to the Trustee such amounts as shall be sufficient
to cover reasonable

27

 

compensation to the Trustee, each predecessor Trustee and their respective agents, attorneys and
counsel, and all other amounts due to the Trustee under Section 6.06.

          Nothing herein contained shall be construed to authorize the Trustee to authorize or consent
to or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement,
adjustment or composition affecting the Debt Securities or the rights of any holder thereof or to
authorize the Trustee to vote in respect of the claim of any Securityholder in any such proceeding.

          All rights of action and of asserting claims under this Indenture, or under any of the Debt
Securities, may be enforced by the Trustee without the possession of any of the Debt Securities, or
the production thereof at any trial or other proceeding relative thereto, and any such suit or
proceeding instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment shall be for the ratable benefit of the holders of the Debt
Securities.

          In any proceedings brought by the Trustee (and also any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the
Trustee shall be held to represent all the holders of the Debt Securities, and it shall not be
necessary to make any holders of the Debt Securities parties to any such proceedings.

          Section 5.03. Application of Moneys Collected by Trustee.

          Any moneys collected by the Trustee shall be applied in the following order, at the date or
dates fixed by the Trustee for the distribution of such moneys, upon presentation of the several
Debt Securities in respect of which moneys have been collected, and stamping thereon the payment,
if only partially paid, and upon surrender thereof if fully paid:

          First: To the payment of costs and expenses incurred by, and reasonable fees of, the
Trustee, its agents, attorneys and counsel, and of all other amounts due to the Trustee under
Section 6.06;

          Second: To the payment of all Senior Indebtedness of the Company if and to the extent
required by Article XV;

          Third: To the payment of the amounts then due and unpaid upon Debt Securities, in respect of
which or for the benefit of which money has been collected, ratably, without preference or priority
of any kind, according to the amounts due on such Debt Securities; and

          Fourth: The balance, if any, to the Company.

          Section 5.04. Proceedings by Securityholders.

          No holder of any Debt Security shall have any right to institute any suit, action or
proceeding for any remedy hereunder, unless such holder previously shall have given to the Trustee
written notice of an Event of Default with respect to the Debt Securities and unless the holders of
not less than 25% in aggregate principal amount of the Debt Securities then outstanding shall have
given the Trustee a written request to institute such action, suit or

28

 

proceeding and shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred thereby, and the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity shall have failed to institute any
such action, suit or proceeding; provided, that no holder of Debt Securities shall have any
right to prejudice the rights of any other holder of Debt Securities, obtain priority or preference
over any other such holder or enforce any right under this Indenture except in the manner herein
provided and for the equal, ratable and common benefit of all holders of Debt Securities.

          Notwithstanding any other provisions in this Indenture, however, the right of any holder of
any Debt Security to receive payment of the principal of, premium, if any, and interest on such
Debt Security when due, or to institute suit for the enforcement of any such payment, shall not be
impaired or affected without the consent of such holder. For the protection and enforcement of the
provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity.

          Section 5.05. Proceedings by Trustee.

          In case of an Event of Default hereunder the Trustee may in its discretion proceed to protect
and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as
the Trustee shall deem most effectual to protect and enforce any of such rights, either by suit in
equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific
enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of
any power granted in this Indenture, or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law.

          Section 5.06. Remedies Cumulative and Continuing.

          Except as otherwise provided in Section 2.06, all powers and remedies given by this Article V
to the Trustee or to the Securityholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any other powers and remedies available to the Trustee or the
holders of the Debt Securities, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or otherwise established
with respect to the Debt Securities, and no delay or omission of the Trustee or of any holder of
any of the Debt Securities to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or shall be construed
to be a waiver of any such default or an acquiescence therein; and, subject to the provisions of
Section 5.04, every power and remedy given by this Article V or by law to the Trustee or to the
Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Securityholders.

          Section 5.07. Direction of Proceedings and Waiver of Defaults by Majority of
Securityholders.

          The holders of a majority in aggregate principal amount of the Debt Securities affected
(voting as one class) at the time outstanding shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee with respect to such Debt Securities;

29

 

provided, however, that (subject to the provisions of Section 6.01) the Trustee
shall have the right to decline to follow any such direction if the Trustee shall determine that
the action so directed would be unjustly prejudicial to the holders not taking part in such
direction or if the Trustee being advised by counsel determines that the action or proceeding so
directed may not lawfully be taken or if a Responsible Officer of the Trustee shall determine that
the action or proceedings so directed would involve the Trustee in personal liability. Prior to any
declaration of acceleration, or ipso facto acceleration, of the maturity of the Debt Securities,
the holders of a majority in aggregate principal amount of the Debt Securities at the time
outstanding may on behalf of the holders of all of the Debt Securities waive (or modify any
previously granted waiver of) any past Default or Event of Default and its consequences, except a
default (a) in the payment of principal of, premium, if any, or interest on any of the Debt
Securities, (b) in respect of covenants or provisions hereof which cannot be modified or amended
without the consent of the holder of each Debt Security affected, or (c) in respect of the
covenants contained in Section 3.09; provided, however, that if the Debt Securities
are held by the Trust or a trustee of the Trust, such waiver or modification to such waiver shall
not be effective until the holders of a majority in liquidation preference of the Trust Securities
of the Trust shall have consented to such waiver or modification to such waiver; provided,
further, that if the consent of the holder of each outstanding Debt Security is required,
such waiver shall not be effective until each holder of the Trust Securities of the Trust shall
have consented to such waiver. Upon any such waiver, the Default or Event of Default covered
thereby shall be deemed to be cured for all purposes of this Indenture and the Company, the Trustee
and the holders of the Debt Securities shall be restored to their former positions and rights
hereunder, respectively; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default
hereunder shall have been waived as permitted by this Section 5.07, said Default or Event of
Default shall for all purposes of the Debt Securities and this Indenture be deemed to have been
cured and to be not continuing.

          Section 5.08. Notice of Defaults.

          The Trustee shall, within 90 days after a Responsible Officer of the Trustee shall have actual
knowledge or received written notice of the occurrence of a default with respect to the Debt
Securities, mail to all Securityholders, as the names and addresses of such holders appear upon the
Debt Security Register, notice of all defaults with respect to the Debt Securities known to the
Trustee, unless such defaults shall have been cured before the giving of such notice (the term
“defaults” for the purpose of this Section 5.08 being hereby defined to be any event specified in
Section 5.01, not including periods of grace, if any, provided for therein); provided,
that, except in the case of default in the payment of the principal of, premium, if any, or
interest on any of the Debt Securities, the Trustee shall be protected in withholding such notice
if and so long as a Responsible Officer of the Trustee in good faith determines that the
withholding of such notice is in the interests of the Securityholders.

          Section 5.09. Undertaking to Pay Costs.

          All parties to this Indenture agree, and each holder of any Debt Security by such holder’s
acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in
any suit for the enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any party

30

 

litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against
any party litigant in such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section 5.09 shall not apply to
any suit instituted by the Trustee, to any suit instituted by any Securityholder, or group of
Securityholders, holding in the aggregate more than 10% in principal amount of the Debt Securities
outstanding, or to any suit instituted by any Securityholder for the enforcement of the payment of
the principal of (or premium, if any) or interest on any Debt Security against the Company on or
after the same shall have become due and payable.

ARTICLE VI

CONCERNING THE TRUSTEE

          Section 6.01. Duties and Responsibilities of Trustee.

          With respect to the holders of Debt Securities issued hereunder, the Trustee, prior to the
occurrence of an Event of Default with respect to the Debt Securities and after the curing or
waiving of all Events of Default which may have occurred, with respect to the Debt Securities,
undertakes to perform such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default with respect to the Debt Securities has occurred (which has
not been cured or waived) the Trustee shall exercise such of the rights and powers vested in it by
this Indenture, and use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of such person’s own affairs.

          No provision of this Indenture shall be construed to relieve the Trustee from liability
for its own negligent action, its own negligent failure to act or its own willful misconduct,
except that:

          (a) prior to the occurrence of an Event of Default with respect to the Debt
Securities and after the curing or waiving of all Events of Default which may have occurred

          (1) the duties and obligations of the Trustee with respect to the Debt Securities shall
be determined solely by the express provisions of this Indenture, and the Trustee shall not
be liable except for the performance of such duties and obligations with respect to the Debt
Securities as are specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and

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

31

 

          (b) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was
negligent in ascertaining the pertinent facts;

          (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by
it in good faith, in accordance with the direction of the Securityholders pursuant to Section 5.07,
relating to the time, method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; and

          (d) the Trustee shall not be charged with knowledge of any Default or Event of Default with
respect to the Debt Securities unless either (1) a Responsible Officer shall have actual knowledge
of such Default or Event of Default or (2) written notice of such Default or Event of Default shall
have been given to the Trustee by the Company or any other obligor on the Debt Securities or by any
holder of the Debt Securities, except with respect to an Event of Default pursuant to Sections
5.01(a), 5.01(b) or 5.01(c) hereof (other than an Event of Default resulting from the default in
the payment of Additional Interest or premium, if any, if the Trustee does not have actual
knowledge or written notice that such payment is due and payable), of which the Trustee shall be
deemed to have knowledge.

          None of the provisions contained in this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur personal financial liability in the performance of any of its
duties or in the exercise of any of its rights or powers.

          Section 6.02. Reliance on Documents, Opinions, etc.

          Except as otherwise provided in Section 6.01:

          (a) the Trustee may conclusively rely and shall be fully protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, bond, note, debenture or other paper or document believed by it in good
faith to be genuine and to have been signed or presented by the proper party or parties;

          (b) any request, direction, order or demand of the Company mentioned herein shall be
sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be
herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy
thereof certified by the Secretary or an Assistant Secretary of the Company;

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

          (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request, order or direction of any of the Securityholders, pursuant to
the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby;

32

 

          (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and
believed by it to be authorized or within the discretion or rights or powers conferred upon it by
this Indenture; nothing contained herein shall, however, relieve the Trustee of the obligation,
upon the occurrence of an Event of Default with respect to the Debt Securities (that has not been
cured or waived) to exercise with respect to the Debt Securities such of the rights and powers
vested in it by this Indenture, and to use the same degree of care and skill in their exercise, as
a prudent person would exercise or use under the circumstances in the conduct of such person’s own
affairs;

          (f) the Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, bond, debenture, coupon or other paper or document, unless requested in writing to
do so by the holders of not less than a majority in principal amount of the outstanding Debt
Securities affected thereby; provided, however, that if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in
the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such expense or liability as a condition to so proceeding; and

          (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents (including any Authenticating Agent) or
attorneys, and the Trustee shall not be responsible for any misconduct or negligence on the part of
any such agent or attorney appointed by it with due care.

          Section 6.03. No Responsibility for Recitals, etc.

          The recitals contained herein and in the Debt Securities (except in the certificate of
authentication of the Trustee or the Authenticating Agent) shall be taken as the statements of the
Company and the Trustee and the Authenticating Agent assume no responsibility for the correctness
of the same. The Trustee and the Authenticating Agent make no representations as to the validity or
sufficiency of this Indenture or of the Debt Securities. The Trustee and the Authenticating Agent
shall not be accountable for the use or application by the Company of any Debt Securities or the
proceeds of any Debt Securities authenticated and delivered by the Trustee or the Authenticating
Agent in conformity with the provisions of this Indenture.

          Section 6.04. Trustee, Authenticating Agent, Paying Agents, Transfer Agents or Registrar
May Own Debt Securities.

          The Trustee or any Authenticating Agent or any Paying Agent or any transfer agent or any Debt
Security registrar, in its individual or any other capacity, may become the owner or pledgee of
Debt Securities with the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, transfer agent or Debt Security registrar.

          Section 6.05. Moneys to be Held in Trust.

          Subject to the provisions of Section 12.04, all moneys received by the Trustee or any paying
agent shall, until used or applied as herein provided, be held in trust for the purpose for which
they were received, but need not be segregated from other funds except to the extent

33

 

required by law. The Trustee and any Paying Agent shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed in writing with the Company. So long as
no Event of Default shall have occurred and be continuing, all interest allowed on any such moneys,
if any, shall be paid from time to time to the Company upon the written order of the Company,
signed by the Chairman of the Board of Directors, the President, the Chief Operating Officer, a
Vice President, the Treasurer or an Assistant Treasurer of the Company.

          Section 6.06. Compensation and Expenses of Trustee.

          The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation as shall be agreed to in writing between the Company and
the Trustee (which shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust), and the Company will pay or reimburse the Trustee upon its written
request for all documented reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any of the provisions of this Indenture (including the reasonable
compensation and the reasonable expenses and disbursements of its counsel and of all Persons not
regularly in its employ) except any such expense, disbursement or advance that arises from its
negligence or bad faith, except as provided in the fee agreement between the Company and the
Trustee dated of even date herewith. The Company also covenants to indemnify each of the Trustee
(including in its individual capacity) and any predecessor Trustee (and its officers, agents,
directors and employees) for, and to hold it harmless against, any and all loss, damage, claim,
liability or expense including taxes (other than taxes based on the income of the Trustee), except
to the extent such loss, damage, claim, liability or expense results from the negligence or bad
faith of such indemnitee, arising out of or in connection with the acceptance or administration of
this trust, including the costs and expenses of defending itself against any claim or liability in
the premises. The obligations of the Company under this Section 6.06 to compensate and indemnify
the Trustee and to pay or reimburse the Trustee for documented expenses, disbursements and advances
shall constitute additional indebtedness hereunder. Such additional indebtedness shall be secured
by a lien prior to that of the Debt Securities upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the benefit of the holders of particular Debt
Securities.

          Without prejudice to any other rights available to the Trustee under applicable law, when the
Trustee incurs expenses or renders services in connection with an Event of Default specified in
subsections (e), (f) or (g) of Section 5.01, the expenses (including the reasonable charges and
expenses of its counsel) and the compensation for the services are intended to constitute expenses
of administration under any applicable federal or state bankruptcy, insolvency or other similar
law.

          The provisions of this Section shall survive the resignation or removal of the Trustee
and the defeasance or other termination of this Indenture.

          Notwithstanding anything in this Indenture or any Debt Security to the contrary, the Trustee
shall have no obligation whatsoever to advance funds to pay any principal of or interest on or
other amounts with respect to the Debt Securities or otherwise advance funds to or on behalf of the
Company.

34

 

          Section 6.07. Officers’ Certificate as Evidence.

          Except as otherwise provided in Sections 6.01 and 6.02, whenever in the administration of the
provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or
bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an
Officers’ Certificate delivered to the Trustee, and such certificate, in the absence of negligence
or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken
or omitted by it under the provisions of this Indenture upon the faith thereof.

          Section 6.08. Eligibility of Trustee.

          The Trustee hereunder shall at all times be a U.S. Person that is a banking corporation or
national association organized and doing business under the laws of the United States of America or
any state thereof or of the District of Columbia and authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least fifty million U.S.
dollars ($50,000,000) and subject to supervision or examination by federal, state, or District of
Columbia authority. If such corporation or national association publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 6.08 the combined capital and surplus of such
corporation or national association shall be deemed to be its combined capital and surplus as set
forth in its most recent records of condition so published.

          The Company may not, nor may any Person directly or indirectly controlling, controlled by, or
under common control with the Company, serve as Trustee, notwithstanding that such corporation or
national association shall be otherwise eligible and qualified under this Article.

          In case at any time the Trustee shall cease to be eligible in accordance with the provisions
of this Section 6.08, the Trustee shall resign immediately in the manner and with the effect
specified in Section 6.09.

          If the Trustee has or shall acquire any “conflicting interest” within the meaning of § 310(b)
of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the
extent and in the manner provided by, and subject to this Indenture.

          Section 6.09. Resignation or Removal of Trustee.

          (a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign
by giving written notice of such resignation to the Company and by mailing notice thereof, at the
Company’s expense, to the holders of the Debt Securities at their addresses as they shall appear on
the Debt Security Register. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee or trustees by written instrument, in duplicate, executed by order of
its Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee
and one copy to the successor Trustee. If no successor Trustee shall have been so appointed and
have accepted appointment within 30 days after the mailing of

35

 

such notice of resignation to the affected Securityholders, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee, or any Securityholder
who has been a bona fide holder of a Debt Security or Debt Securities for at least six months may,
subject to the provisions of Section 5.09, on behalf of himself or herself and all others similarly
situated, petition any such court for the appointment of a successor Trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
Trustee.

          (b) In case at any time any of the following shall occur —

          (1) the Trustee shall fail to comply with the provisions of the last paragraph
of Section 6.08 after written request therefor by the Company or by any
Securityholder who has been a bona fide holder of a Debt Security or Debt Securities
for at least six months,

          (2) the Trustee shall cease to be eligible in accordance with the provisions of
Section 6.08 and shall fail to resign after written request therefor by the Company
or by any such Securityholder, or

          (3) the Trustee shall become incapable of acting, or shall be adjudged bankrupt
or insolvent, or a receiver of the Trustee or of its property shall be appointed, or
any public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, the Company may remove the Trustee and appoint a successor Trustee by
written instrument, in duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the successor Trustee, or,
subject to the provisions of Section 5.09, if no successor Trustee shall have been so appointed and
have accepted appointment within 30 days of the occurrence of any of (1),(2) or (3) above, any
Securityholder who has been a bona fide holder of a Debt Security or Debt Securities for at least
six months may, on behalf of himself or herself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor Trustee.

          (c) Upon prior written notice to the Company and the Trustee, the holders of a majority in
aggregate principal amount of the Debt Securities at the time outstanding may at any time remove
the Trustee and nominate a successor Trustee, which shall be deemed appointed as successor Trustee
unless within ten Business Days after such nomination the Company objects thereto, in which case or
in the case of a failure by such holders to nominate a successor Trustee, the Trustee so removed or
any Securityholder, upon the terms and conditions and otherwise as in subsection (a) of this
Section 6.09 provided, may petition any court of competent jurisdiction for an appointment of a
successor.

          (d) Any resignation or removal of the Trustee and appointment of a successor Trustee pursuant
to any of the provisions of this Section 6.09 shall become effective upon acceptance of appointment
by the successor Trustee as provided in Section 6.10.

36

 

          Section 6.10. Acceptance by Successor Trustee.

          Any successor Trustee appointed as provided in Section 6.09 shall execute, acknowledge and
deliver to the Company and to its predecessor Trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the retiring Trustee shall become effective
and such successor Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, duties and obligations with respect to the Debt Securities of its
predecessor hereunder, with like effect as if originally named as Trustee herein; but,
nevertheless, on the written request of the Company or of the successor Trustee, the Trustee
ceasing to act shall, upon payment of the amounts then due it pursuant to the provisions of Section
6.06, execute and deliver an instrument transferring to such successor Trustee all the rights and
powers of the Trustee so ceasing to act and shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of
any such successor Trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor Trustee all such rights and powers.
Any Trustee ceasing to act shall, nevertheless, retain a lien upon all property or funds held or
collected by such Trustee to secure any amounts then due it pursuant to the provisions of Section
6.06.

          If a successor Trustee is appointed, the Company, the retiring Trustee and the successor
Trustee shall execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Debt Securities as to which the predecessor
Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or
change any of the provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the Trust hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be Trustee of a trust or trusts hereunder separate and
apart from any trust or trusts hereunder administered by any other such Trustee.

          No successor Trustee shall accept appointment as provided in this Section 6.10 unless at the
time of such acceptance such successor Trustee shall be eligible under the provisions of Section
6.08.

          In no event shall a retiring Trustee be liable for the acts or omissions of any successor
Trustee hereunder.

          Upon acceptance of appointment by a successor Trustee as provided in this Section 6.10, the
Company shall mail notice of the succession of such Trustee hereunder to the holders of Debt
Securities at their addresses as they shall appear on the Debt Security Register. If the Company
fails to mail such notice within ten Business Days after the acceptance of appointment by the
successor Trustee, the successor Trustee shall cause such notice to be mailed at the expense of the
Company.

          Section 6.11. Succession by Merger, etc.

37

 

          Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder without
the execution or filing of any paper or any further act on the part of any of the parties hereto;
provided, that such corporation shall be otherwise eligible and qualified under this
Article.

          In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture any of the Debt Securities shall have been authenticated but not delivered, any such
successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee,
and deliver such Debt Securities so authenticated; and in case at that time any of the Debt
Securities shall not have been authenticated, any successor to the Trustee may authenticate such
Debt Securities either in the name of any predecessor hereunder or in the name of the successor
Trustee; and in all such cases such certificates shall have the full force which it is anywhere in
the Debt Securities or in this Indenture provided that the certificate of the Trustee shall have;
provided, however, that the right to adopt the certificate of authentication of any
predecessor Trustee or authenticate Debt Securities in the name of any predecessor Trustee shall
apply only to its successor or successors by merger, conversion or consolidation.

          Section 6.12. Authenticating Agents.

          There may be one or more Authenticating Agents appointed by the Trustee upon
the request of the Company with power to act on its behalf and subject to its direction in the
authentication and delivery of Debt Securities issued upon exchange or registration of
transfer
thereof as fully to all intents and purposes as though any such Authenticating Agent had been
expressly authorized to authenticate and deliver Debt Securities; provided, that the
Trustee shall
have no liability to the Company for any acts or omissions of the Authenticating Agent with
respect to the authentication and delivery of Debt Securities. Any such Authenticating Agent
shall at all times be a banking corporation or national association organized and doing
business
under the laws of the United States or of any state or territory thereof or of the District of
Columbia authorized under such laws to act as Authenticating Agent, having a combined capital
and surplus of at least $50,000,000 and being subject to supervision or examination by
federal,
state, territorial or District of Columbia authority. If such banking corporation or national
association publishes reports of condition at least annually pursuant to law or the
requirements of
such authority, then for the purposes of this Section 6.12 the combined capital and surplus of
such corporation shall be deemed to be its combined capital and surplus as set forth in its
most
recent report of condition so published. If at any time an Authenticating Agent shall cease to
be
eligible in accordance with the provisions of this Section, it shall resign immediately in the
manner and with the effect herein specified in this Section.

          Any corporation into which any Authenticating Agent may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, consolidation or conversion
to which any Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of any Authenticating Agent, shall be the
successor of such Authenticating Agent hereunder, if such

38

 

successor corporation is otherwise eligible under this Section 6.12 without the execution or filing
of any paper or any further act on the part of the parties hereto or such Authenticating Agent.

          Any Authenticating Agent may at any time resign by giving written notice of resignation to the
Trustee and to the Company. The Trustee may at any time terminate the agency of any Authenticating
Agent with respect to the Debt Securities by giving written notice of termination to such
Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be eligible under this
Section 6.12, the Trustee may, and upon the request of the Company shall, promptly appoint a
successor Authenticating Agent eligible under this Section 6.12, shall give written notice of such
appointment to the Company and shall mail notice of such appointment to all holders of Debt
Securities as the names and addresses of such holders appear on the Debt Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested
with all rights, powers, duties and responsibilities with respect to the Debt Securities of its
predecessor hereunder, with like effect as if originally named as Authenticating Agent herein.

          The Company agrees to pay to any Authenticating Agent from time to time reasonable
compensation for its services. Any Authenticating Agent shall have no responsibility or liability
for any action taken by it as such in accordance with the directions of the Trustee.

ARTICLE VII

CONCERNING THE SECURITYHOLDERS

          Section 7.01. Action by Securityholders.

          Whenever in this Indenture it is provided that the holders of a specified percentage in
aggregate principal amount of the Debt Securities may take any action (including the making of any
demand or request, the giving of any notice, consent or waiver or the taking of any other action),
the fact that at the time of taking any such action the holders of such specified percentage have
joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor
executed by such Securityholders in person or by agent or proxy appointed in writing, or (b) by the
record of such holders of Debt Securities voting in favor thereof at any meeting of such
Securityholders duly called and held in accordance with the provisions of Article VIII, or (c) by a
combination of such instrument or instruments and any such record of such a meeting of such
Securityholders or (d) by any other method the Trustee deems satisfactory.

          If the Company shall solicit from the Securityholders any request, demand, authorization,
direction, notice, consent, waiver or other action or revocation of the same, the Company may, at
its option, as evidenced by an Officers’ Certificate, fix in advance a record date for such Debt
Securities for the determination of Securityholders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other action or revocation of the same, but
the Company shall have no obligation to do so. If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other action or revocation of the same
may be given before or after the record date, but only the Securityholders of record at

39

 

the close of business on the record date shall be deemed to be Securityholders for the purposes of
determining whether Securityholders of the requisite proportion of outstanding Debt Securities have
authorized or agreed or consented to such request, demand, authorization, direction, notice,
consent, waiver or other action or revocation of the same, and for that purpose the outstanding
Debt Securities shall be computed as of the record date; provided, however, that no
such authorization, agreement or consent by such Securityholders on the record date 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.

          Section 7.02. Proof of Execution by Securityholders.

          Subject to the provisions of Sections 6.01, 6.02 and 8.05, proof of the execution of any
instrument by a Securityholder or such Securityholder’s agent or proxy shall be sufficient if made
in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in
such manner as shall be satisfactory to the Trustee. The ownership of Debt Securities shall be
proved by the Debt Security Register or by a certificate of the Debt Security registrar. The
Trustee may require such additional proof of any matter referred to in this Section as it shall
deem necessary.

          The record of any Securityholders’ meeting shall be proved in the manner provided in
Section 8.06.

          Section 7.03. Who Are Deemed Absolute Owners.

          Prior to due presentment for registration of transfer of any Debt Security, the Company, the
Trustee, any Authenticating Agent, any Paying Agent, any transfer agent and any Debt Security
registrar may deem the Person in whose name such Debt Security shall be registered upon the Debt
Security Register to be, and may treat such Person as, the absolute owner of such Debt Security
(whether or not such Debt Security shall be overdue) for the purpose of receiving payment of or on
account of the principal of, premium, if any, and interest on such Debt Security and for all other
purposes; and neither the Company nor the Trustee nor any Authenticating Agent nor any Paying Agent
nor any transfer agent nor any Debt Security registrar shall be affected by any notice to the
contrary. All such payments so made to any holder for the time being or upon such holder’s order
shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge
the liability for moneys payable upon any such Debt Security.

          Section 7.04. Debt Securities Owned by Company Deemed Not Outstanding.

          In determining whether the holders of the requisite aggregate principal amount of Debt
Securities have concurred in any direction, consent or waiver under this Indenture, Debt Securities
which are owned by the Company or any other obligor on the Debt Securities or by any Person
directly or indirectly controlling or controlled by or under direct or indirect common control with
the Company (other than the Trust) or any other obligor on the Debt Securities shall be disregarded
and deemed not to be outstanding for the purpose of any such determination; provided, that
for the purposes of determining whether the Trustee shall be protected in relying on any such
direction, consent or waiver, only Debt Securities which a Responsible Officer of

40

 

the Trustee actually knows are so owned shall be so disregarded. Debt Securities so owned which
have been pledged in good faith may be regarded as outstanding for the purposes of this Section
7.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote
such Debt Securities and that the pledgee is not the Company or any such other obligor or Person
directly or indirectly controlling or controlled by or under direct or indirect common control with
the Company or any such other obligor. In the case of a dispute as to such right, any decision by
the Trustee taken upon the advice of counsel shall be full protection to the Trustee.

          Section 7.05. Revocation of Consents; Future Holders Bound.

          At any time prior to (but not after) the evidencing to the Trustee, as provided in Section
7.01, of the taking of any action by the holders of the percentage in aggregate principal amount of
the Debt Securities specified in this Indenture in connection with such action, any holder (in
cases where no record date has been set pursuant to Section 7.01) or any holder as of an applicable
record date (in cases where a record date has been set pursuant to Section 7.01) of a Debt Security
(or any Debt Security issued in whole or in part in exchange or substitution therefor) the serial
number of which is shown by the evidence to be included in the Debt Securities the holders of which
have consented to such action may, by filing written notice with the Trustee at the Principal
Office of the Trustee and upon proof of holding as provided in Section 7.02, revoke such action so
far as concerns such Debt Security (or so far as concerns the principal amount represented by any
exchanged or substituted Debt Security). Except as aforesaid any such action taken by the holder of
any Debt Security shall be conclusive and binding upon such holder and upon all future holders and
owners of such Debt Security, and of any Debt Security issued in exchange or substitution therefor
or on registration of transfer thereof, irrespective of whether or not any notation in regard
thereto is made upon such Debt Security or any Debt Security issued in exchange or substitution
therefor.

          The Trustee may at any time call a meeting of Securityholders to take any action specified in
Section 8.01, to be held at such time and at such place in New York or Wilmington, Delaware, as the
Trustee shall determine. Notice of every meeting of the Securityholders, setting forth the time and
the place of such meeting and in general terms the action proposed to be taken at such meeting,
shall be mailed to holders of Debt Securities affected at their addresses as they shall appear on

prior to the date fixed for the meeting.

          Section 8.03. Call of Meetings by Company or Securityholders.

          In case at any time the Company pursuant to a Board Resolution, or the holders of at least 10%

have requested the Trustee to call a meeting of Securityholders, by written request setting forth
in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have
mailed the notice of such meeting within 20 days after receipt of such request, then the Company or
such Securityholders may determine the time and the place in Quincy, Illinois for such meeting and
may call such meeting to take any action authorized in Section 8.01, by mailing notice thereof as
provided in Section 8.02.

          Section 8.04. Qualifications for Voting.

          Section 8.05. Regulations.

          Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable

duties of inspectors of votes, the submission and examination of proxies, certificates and other
evidence of the right to vote, and such other matters concerning the conduct of the meeting as it
shall deem appropriate.

          The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting,

written reports in triplicate of all votes cast at the meeting. A record in duplicate of the
proceedings of each meeting of Securityholders shall be prepared by the secretary of the meeting
and there shall be attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts
setting forth a copy of the notice of the meeting and showing that said notice was mailed as

notice, authorization, direction or other action which may be given by the holders of not less than

scheduled to be reconvened. Notice of the reconvening of an adjourned meeting shall state expressly
the percentage, as provided above, of the outstanding principal amount of the Debt Securities which
shall constitute a quorum.

presented to a meeting or adjourned meeting duly reconvened at which a quorum is present as
aforesaid may be adopted by the affirmative vote of the holders of not less than a majority in
outstanding principal amount of the Debt Securities; provided, however, that,
except as limited by the proviso in the first paragraph of Section 9.02, any resolution with

ARTICLE IX

SUPPLEMENTAL INDENTURES

          Section 9.01. Supplemental Indentures without Consent of Securityholders.

          The Company, when authorized by a Board Resolution, and the Trustee may from time to time and
at any time enter into an indenture or indentures supplemental hereto, without the consent of the
Securityholders, for one or more of the following purposes:

          (a) to evidence the succession of another corporation to the Company, or successive
successions, and the assumption by the successor corporation of the covenants, agreements and
obligations of the Company, pursuant to Article XI hereof;

          (b) to add to the covenants of the Company such further covenants, restrictions or conditions
for the protection of the holders of Debt Securities as the Board of Directors shall consider to be
for the protection of the holders of such Debt Securities, and to make the occurrence, or the
occurrence and continuance, of a Default in any of such additional covenants, restrictions or
conditions a Default or an Event of Default permitting the enforcement of all or any of the several
remedies provided in this Indenture as herein set forth; provided,

44

 

however, that in respect of any such additional covenant, restriction or condition such
supplemental indenture may provide for a particular period of grace after Default (which period may
be shorter or longer than that allowed in the case of other Defaults) or may provide for an
immediate enforcement upon such Default or may limit the remedies available to the Trustee upon
such default;

          (c) to cure any ambiguity or to correct or supplement any provision contained herein or in any
supplemental indenture which may be defective or inconsistent with any other provision contained
herein or in any supplemental indenture, or to make such other provisions in regard to matters or
questions arising under this Indenture; provided, that any such action shall not adversely
affect the interests of the holders of the Debt Securities;

          (d) to add to, delete from, or revise the terms of Debt Securities, including, without
limitation, any terms relating to the issuance, exchange, registration or transfer of Debt
Securities, including to provide for transfer procedures and restrictions substantially similar to
those applicable to the Capital Securities, as required by Section 2.05 (for purposes of assuring
that no registration of Debt Securities is required under the Securities Act; provided,
that any such action shall not adversely affect the interests of the holders of the Debt Securities
then outstanding (it being understood, for purposes of this proviso, that transfer restrictions on
Debt Securities substantially similar to those applicable to Capital Securities shall not be deemed
to adversely affect the holders of the Debt Securities);

          (e) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee
with respect to the Debt Securities and to add to or change any of the provisions of this Indenture
as shall be necessary to provide for or facilitate the administration of the trusts hereunder by
more than one Trustee, pursuant to the requirements of Section 6.10;

          (f) to make any change (other than as elsewhere provided in this paragraph) that does
not adversely affect the rights of any Securityholder in any material respect; or

          (g) to provide for the issuance of and establish the form and terms and conditions of
the Debt Securities, to establish the form of any certifications required to be furnished pursuant
to the terms of this Indenture or the Debt Securities, or to add to the rights of the holders of
Debt Securities.

          The Trustee is hereby authorized to join with the Company in the execution of any such
supplemental indenture, to make any further appropriate agreements and stipulations which may be
therein contained and to accept the conveyance, transfer and assignment of any property thereunder,
but the Trustee shall not be obligated to, but may in its discretion, enter into any such
supplemental indenture which affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise.

          Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed
by the Company and the Trustee without the consent of the holders of any of the Debt Securities at
the time outstanding, notwithstanding any of the provisions of Section 9.02.

          Section 9.02. Supplemental Indentures with Consent of Securityholders.

45

 

          With the consent (evidenced as provided in Section 7.01) of the holders of not less than a
majority in aggregate principal amount of the Debt Securities at the time outstanding affected by
such supplemental indenture (voting as a class), the Company, when authorized by a Board
Resolution, and the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act,
then in effect, applicable to indentures qualified thereunder) for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner the rights of the holders of the Debt
Securities; provided, however, that no such supplemental indenture shall without
such consent of the holders of each Debt Security then outstanding and affected thereby (i) extend
the fixed maturity of any Debt Security, or reduce the principal amount thereof or any premium
thereon, or reduce the rate or extend the time of payment of interest thereon, or reduce any amount
payable on redemption thereof or make the principal thereof or any interest or premium thereon
payable in any coin or currency other than that provided in the Debt Securities, or impair or
affect the right of any Securityholder to institute suit for payment thereof or impair the right of
repayment, if any, at the option of the holder, or (ii) reduce the aforesaid percentage of Debt
Securities the holders of which are required to consent to any such supplemental indenture; and
provided, further, that if the Debt Securities are held by the Trust or a trustee
of such trust, such supplemental indenture shall not be effective until the holders of a majority
in liquidation preference of the Trust Securities shall have consented to such supplemental
indenture; provided, further, that if the consent of the Securityholder of each
outstanding Debt Security is required, such supplemental indenture shall not be effective until
each holder of the Trust Securities shall have consented to such supplemental indenture.

          Upon the request of the Company accompanied by a Board Resolution authorizing the execution of
any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of
Securityholders as aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties
or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion,
but shall not be obligated to, enter into such supplemental indenture.

          Promptly after the execution by the Company and the Trustee of any supplemental indenture
pursuant to the provisions of this Section, the Trustee shall transmit by mail, first class postage
prepaid, a notice, prepared by the Company, setting forth in general terms the substance of such
supplemental indenture, to the Securityholders as their names and addresses appear upon the Debt
Security Register. Any failure of the Trustee to mail such notice, or any defect therein, shall
not, however, in any way impair or affect the validity of any such supplemental indenture.

          It shall not be necessary for the consent of the Securityholders under this Section 9.02 to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof.

          Section 9.03. Effect of Supplemental Indentures.

46

 

          Upon the execution of any supplemental indenture pursuant to the provisions of this Article
IX, this Indenture shall be and be deemed to be modified and amended in accordance therewith and
the respective rights, limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of Debt Securities shall thereafter be
determined, exercised and enforced hereunder subject in all respects to such modifications and
amendments and all the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all purposes.

          Section 9.04. Notation on Debt Securities.

          Debt Securities authenticated and delivered after the execution of any supplemental indenture
pursuant to the provisions of this Article IX may bear a notation as to any matter provided for in
such supplemental indenture. If the Company or the Trustee shall so determine, new Debt Securities
so modified as to conform, in the opinion of the Board of Directors of the Company, to any
modification of this Indenture contained in any such supplemental indenture may be prepared and
executed by the Company, authenticated by the Trustee or the Authenticating Agent and delivered in
exchange for the Debt Securities then outstanding.

          Section 9.05. Evidence of Compliance of Supplemental Indenture to be Furnished
to Trustee.

          The Trustee, subject to the provisions of Sections 6.01 and 6.02, shall, in addition to the
documents required by Section 14.06, receive an Officers’ Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto complies with the
requirements of this Article IX. The Trustee shall receive an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article IX is authorized or
permitted by, and conforms to, the terms of this Article IX and that it is proper for the Trustee
under the provisions of this Article IX to join in the execution thereof.

redemption at least 30 and not more than 60 days prior to the date fixed for redemption to the
holders of Debt Securities so to be redeemed as a whole or in part at their last addresses as the
same appear on the Debt Security Register. Such mailing shall be by first class mail. The notice if
mailed in the manner herein provided shall be conclusively presumed to have been duly given,
whether or not the holder receives such notice. In any case, failure to give such notice by mail or
any defect in the notice to the holder of any Debt Security designated for redemption as a whole or
in part shall not affect the validity of the proceedings for the redemption of any other Debt
Security.

          Each such notice of redemption shall specify the CUSIP number, if any, of the Debt Securities
to be redeemed, the date fixed for redemption, the redemption price at which Debt Securities are to
be redeemed, the place or places of payment, that payment will be made upon presentation and
surrender of such Debt Securities, that interest accrued to the date fixed for redemption will be
paid as specified in said notice, and that on and after said date interest thereon or on the
portions thereof to be redeemed will cease to accrue. If less than all the Debt Securities are to
be redeemed the notice of redemption shall specify the numbers of the Debt Securities to be
redeemed. In case the Debt Securities are to be redeemed in part only, the notice of redemption
shall state the portion of the principal amount thereof to be redeemed and shall state that on and
after the date fixed for redemption, upon surrender of such Debt Security, a new Debt Security or
Debt Securities in principal amount equal to the unredeemed portion thereof will be issued.

          Prior to 10:00 a.m. New York City time on the Redemption Date or the Special Redemption Date
specified in the notice of redemption given as provided in this Section, the Company will deposit
with the Trustee or with one or more Paying Agents an amount of money sufficient to redeem on the
redemption date all the Debt Securities so called for redemption at the appropriate redemption
price, together with accrued interest to the date fixed for redemption.

          The Company will give the Trustee notice not less than 45 nor more than 60 days prior to the
redemption date as to the redemption price at which the Debt Securities are to be redeemed and the
aggregate principal amount of Debt Securities to be redeemed and the Trustee shall select, in such
manner as in its sole discretion it shall deem appropriate and fair, the Debt Securities or
portions thereof (in integral multiples of $1,000) to be redeemed.

          Section 10.04. Payment of Debt Securities Called for Redemption.

          If notice of redemption has been given as provided in Section 10.03, the Debt Securities or
portions of Debt Securities with respect to which such notice has been given shall become due and
payable on the Redemption Date or the Special Redemption Date (as the case may be) and at the place
or places stated in such notice at the applicable redemption price,

48

 

together with interest accrued to the date fixed for redemption, and on and after said Redemption
Date or the Special Redemption Date (unless the Company shall default in the payment of such Debt
Securities at the redemption price, together with interest accrued to said date) interest on the
Debt Securities or portions of Debt Securities so called for redemption shall cease to accrue. On
presentation and surrender of such Debt Securities at a place of payment specified in said notice,
such Debt Securities or the specified portions thereof shall be paid and redeemed by the Company at
the applicable redemption price, together with interest accrued thereon to the Redemption Date or
the Special Redemption Date (as the case may be).

          Upon presentation of any Debt Security redeemed in part only, the Company shall execute and
the Trustee shall authenticate and make available for delivery to the holder thereof, at the
expense of the Company, a new Debt Security or Debt Securities of authorized denominations in
principal amount equal to the unredeemed portion of the Debt Security so presented.

ARTICLE XI

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

          Section 11.01. Company May Consolidate, etc., on Certain Terms.

          Nothing contained in this Indenture or in the Debt Securities shall prevent any consolidation
or merger of the Company with or into any other corporation or corporations (whether or not
affiliated with the Company) or successive consolidations or mergers in which the Company or its
successor or successors shall be a party or parties, or shall prevent any sale, conveyance,
transfer or other disposition of the property or capital stock of the Company or its successor or
successors as an entirety, or substantially as an entirety, to any other corporation (whether or
not affiliated with the Company, or its successor or successors) authorized to acquire and operate
the same; provided, however, that the Company hereby covenants and agrees that,
upon any such consolidation, merger (where the Company is not the surviving corporation), sale,
conveyance, transfer or other disposition, the due and punctual payment of all payments due on all
of the Debt Securities in accordance with their terms, according to their tenor, and the due and
punctual performance and observance of all the covenants and conditions of this Indenture to be
kept or performed by the Company, shall be expressly assumed by supplemental indenture reasonably
satisfactory in form to the Trustee executed and delivered to the Trustee by the entity formed by
such consolidation, or into which the Company shall have been merged, or by the entity which shall
have acquired such property or capital stock.

          Section 11.02. Successor Entity to be Substituted.

          In case of any such consolidation, merger, sale, conveyance, transfer or other disposition
contemplated in Section 11.01 and upon the assumption by the successor entity, by supplemental

Trustee, of the due and punctual payment of the principal of and premium, if any, and interest on
all of the Debt Securities and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed or observed by the Company, such
successor entity shall succeed to and be substituted for the Company, with the

49

 

same effect as if it had been named herein as the Company, and thereupon the predecessor entity
shall be relieved of any further liability or obligation hereunder or upon the Debt Securities.
Such successor entity thereupon may cause to be signed, and may issue either in its own name or in
the name of the Company, any or all of the Debt Securities issuable hereunder which theretofore
shall not have been signed by the Company and delivered to the Trustee or the Authenticating Agent;
and, upon the order of such successor entity instead of the Company and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee or the Authenticating Agent
shall authenticate and deliver any Debt Securities which previously shall have been signed and
delivered by the officers of the Company, to the Trustee or the Authenticating Agent for
authentication, and any Debt Securities which such successor entity thereafter shall cause to be
signed and delivered to the Trustee or the Authenticating Agent for that purpose. All the Debt
Securities so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Debt Securities theretofore or thereafter issued in accordance with the terms of
this Indenture as though all of such Debt Securities had been issued at the date of the execution
hereof.

          Section 11.03. Opinion of Counsel to be Given to Trustee.

          The Trustee, subject to the provisions of Sections 6.01 and 6.02, shall receive, in addition

that any consolidation, merger, sale, conveyance, transfer or other disposition, and any
assumption, permitted or required by the terms of this Article XI complies with the provisions of
this Article XI.

6.09 and 12.04 hereof, which shall survive until such Debt Securities shall mature or are redeemed,

Debt Securities.

particular Debt Securities for the payment of which such moneys have been deposited with the
Trustee, of all sums due and to become due thereon for principal, and premium, if any, and
interest.

          Section 12.03. Paying Agent to Repay Moneys Held.

          Upon the satisfaction and discharge of this Indenture, all moneys then held by any Paying

further liability with respect to such moneys.

of, and premium, if any, or interest on such Debt Securities, as the case may be, shall have become
due and payable, shall be repaid to the Company by the Trustee or such Paying Agent on written
demand; and the holder of any of the Debt Securities shall thereafter look only to the Company for
any payment which such holder may be entitled to collect and all liability of the Trustee or such
Paying Agent with respect to such moneys shall thereupon cease.

          Notwithstanding anything to the contrary contained herein, if any Interest Payment Date, other

          Section 14.08. Table of Contents, Headings, etc.

          The table of contents and the titles and headings of the articles and sections of this

construed as if such invalid or illegal or unenforceable provision had never been contained herein
or therein.

          Section 14.11. Assignment.

          Subject to Article XI, the Company will have the right at all times to assign any of its

          Section 14.12. Acknowledgment of Rights.

          The Company acknowledges that, with respect to any Debt Securities held by the Trust or the

rights under this Indenture as the holder of Debt Securities held as the assets of the Trust after
the holders of a majority in Liquidation Amount of the Capital Securities of the Trust have so
directed in writing such Institutional Trustee, a holder of record of such Capital Securities may
to the fullest extent permitted by law institute legal proceedings directly against the Company to
enforce such Institutional Trustee’s rights under this Indenture without first instituting any
legal proceedings against such Institutional Trustee or any other Person. Notwithstanding the
foregoing, if an Event of Default has occurred and is continuing and such event is attributable to
the failure of the Company to pay interest (or premium, if any) or principal on the Debt Securities
on the date such interest (or premium, if any) or principal is

54

 

otherwise due and payable (or in the case of redemption, on the redemption date), the Company
acknowledges that a holder of record of Capital Securities of the Trust may directly institute a
proceeding against the Company for enforcement of payment to such holder directly of the principal
of (or premium, if any) or interest on the Debt Securities having an aggregate principal amount
equal to the aggregate Liquidation Amount of the Capital Securities of such holder on or after the
respective due date specified in the Debt Securities.

ARTICLE XV

SUBORDINATION OF DEBT SECURITIES

          Section 15.01. Agreement to Subordinate.

          The Company covenants and agrees, and each holder of Debt Securities issued hereunder and
under any supplemental indenture (the “Additional Provisions”) by such Securityholder’s acceptance
thereof likewise covenants and agrees, that all Debt Securities shall be issued subject to the
provisions of this Article XV; and each holder of a Debt Security, whether upon original issue or
upon transfer or assignment thereof, accepts and agrees to be bound by such provisions.

          The payment by the Company of the payments due on all Debt Securities issued hereunder and
under any Additional Provisions shall, to the extent and in the manner hereinafter set forth, be
subordinated and junior in right of payment to the prior payment in full of all Senior Indebtedness
of the Company, whether outstanding at the date of this Indenture or thereafter incurred.

          No provision of this Article XV shall prevent the occurrence of any default or Event of
Default hereunder.

          Section 15.02. Default on Senior Indebtedness.

          In the event and during the continuation of any default by the Company in the payment of
principal, premium, interest or any other payment due on any Senior Indebtedness of the Company
following any applicable grace period, or in the event that the maturity of any Senior Indebtedness
of the Company has been accelerated because of a default, and such acceleration has not been
rescinded or canceled and such Senior Indebtedness has not been paid in full then, in either case,
no payment shall be made by the Company with respect to the payments due on the Debt Securities.

          In the event that, notwithstanding the foregoing, any payment shall be received by the Trustee
when such payment is prohibited by the preceding paragraph of this Section 15.02, such payment
shall, subject to Section 15.06, be held in trust for the benefit of, and shall be paid over or
delivered to, the holders of Senior Indebtedness or their respective representatives, or to the
trustee or trustees under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent that the holders of
the Senior Indebtedness (or their representative or representatives or a trustee) notify the
Trustee in writing within 90 days of such payment of the amounts then due and owing on the

55

 

Senior Indebtedness and only the amounts specified in such notice to the Trustee shall be paid to
the holders of Senior Indebtedness.

          Section 15.03. Liquidation; Dissolution; Bankruptcy.

          Upon any payment by the Company or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to creditors upon any dissolution or winding-up
or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all amounts due upon all Senior Indebtedness of the
Company shall first be paid in full, or payment thereof provided for in money in accordance with
its terms, before any payment is made by the Company on the Debt Securities; and upon any such
dissolution or winding-up or liquidation or reorganization, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash, property or
securities, to which the Securityholders or the Trustee would be entitled to receive from the
Company, except for the provisions of this Article XV, shall be paid by the Company, or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Securityholders or by the Trustee under this Indenture if received by them
or it, directly to the holders of Senior Indebtedness of the Company (pro rata to such holders on
the basis of the respective amounts of Senior Indebtedness held by such holders, as calculated by
the Company) or their representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness may have been
issued, as their respective interests may appear, to the extent necessary to pay such Senior
Indebtedness in full, in money or money’s worth, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness, before any payment or distribution
is made to the Securityholders or to the Trustee.

          In the event that, notwithstanding the foregoing, any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, prohibited by the
foregoing, shall be received by the Trustee or any Securityholder before all Senior Indebtedness of
the Company is paid in full, or provision is made for such payment in money in accordance with its
terms, such payment or distribution shall be held in trust for the benefit of and shall be paid
over or delivered to the holders of such Senior Indebtedness or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to which any
instruments evidencing such Senior Indebtedness may have been issued, as their respective interests
may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness
of the Company remaining unpaid to the extent necessary to pay such Senior Indebtedness in full in
money in accordance with its terms, after giving effect to any concurrent payment or distribution
to or for the benefit of the holders of such Senior Indebtedness.

          For purposes of this Article XV, the words “cash, property or securities” shall not be deemed
to include shares of stock of the Company as reorganized or readjusted, or securities of the
Company or any other corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this Article XV with respect to
the Debt Securities to the payment of all Senior Indebtedness of the Company, that may at the time
be outstanding, provided, that (a) such Senior Indebtedness is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment,

56

 

and (b) the rights of the holders of such Senior Indebtedness are not, without the consent of such
holders, altered by such reorganization or readjustment. The consolidation of the Company with, or
the merger of the Company into, another corporation or the liquidation or dissolution of the
Company following the conveyance or transfer of its property as an entirety, or substantially as an
entirety, to another corporation upon the terms and conditions provided for in Article XI of this
Indenture shall not be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Section 15.03 if such other corporation shall, as a part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article XI of this Indenture.
Nothing in Section 15.02 or in this Section 15.03 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.06 of this Indenture.

          Section 15.04. Subrogation.

          Subject to the payment in full of all Senior Indebtedness of the Company, the Securityholders
shall be subrogated to the rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company applicable to such Senior Indebtedness
until all payments due on the Debt Securities shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of such Senior Indebtedness of any cash,
property or securities to which the Securityholders or the Trustee would be entitled except for the
provisions of this Article XV, and no payment over pursuant to the provisions of this Article XV to
or for the benefit of the holders of such Senior Indebtedness by Securityholders or the Trustee,
shall, as between the Company, its creditors other than holders of Senior Indebtedness of the
Company, and the holders of the Debt Securities be deemed to be a payment or distribution by the
Company to or on account of such Senior Indebtedness. It is understood that the provisions of this
Article XV are and are intended solely for the purposes of defining the relative rights of the
holders of the Debt Securities, on the one hand, and the holders of such Senior Indebtedness, on
the other hand.

          Nothing contained in this Article XV or elsewhere in this Indenture, any Additional Provisions
or in the Debt Securities is intended to or shall impair, as between the Company, its creditors
other than the holders of Senior Indebtedness of the Company, and the holders of the Debt
Securities, the obligation of the Company, which is absolute and unconditional, to pay to the
holders of the Debt Securities all payments on the Debt Securities as and when the same shall
become due and payable in accordance with their terms, or is intended to or shall affect the
relative rights of the holders of the Debt Securities and creditors of the Company, other than the
holders of Senior Indebtedness of the Company, nor shall anything herein or therein prevent the
Trustee or the holder of any Debt Security from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any, under this Article
XV of the holders of such Senior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy.

          Upon any payment or distribution of assets of the Company referred to in this Article XV, the
Trustee, subject to the provisions of Article VI of this Indenture, and the Securityholders shall
be entitled to conclusively rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding-up, liquidation or reorganization proceedings are
pending, or a certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent or
other Person making such payment or distribution, delivered to the Trustee or to

57

 

the Securityholders, for the purposes of ascertaining the Persons entitled to participate in such
distribution, the holders of Senior Indebtedness and other indebtedness of the Company, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article XV.

          Section 15.05. Trustee to Effectuate Subordination.

          Each Securityholder by such Securityholder’s acceptance thereof authorizes and directs the
Trustee on such Securityholder’s behalf to take such action as may be necessary or appropriate to
effectuate the subordination provided in this Article XV and appoints the Trustee such
Securityholder’s attorney-in-fact for any and all such purposes.

          Section 15.06. Notice by the Company.

          The Company shall give prompt written notice to a Responsible Officer of the Trustee at the
Principal Office of the Trustee of any fact known to the Company that would prohibit the making of
any payment of moneys to or by the Trustee in respect of the Debt Securities pursuant to the
provisions of this Article XV. Notwithstanding the provisions of this Article XV or any other
provision of this Indenture or any Additional Provisions, the Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any payment of moneys to
or by the Trustee in respect of the Debt Securities pursuant to the provisions of this Article XV,
unless and until a Responsible Officer of the Trustee at the Principal Office of the Trustee shall
have received written notice thereof from the Company or a holder or holders of Senior Indebtedness
or from any trustee therefor; and before the receipt of any such written notice, the Trustee,
subject to the provisions of Article VI of this Indenture, shall be entitled in all respects to
assume that no such facts exist; provided, however, that if the Trustee shall not
have received the notice provided for in this Section 15.06 at least two Business Days prior to the
date upon which by the terms hereof any money may become payable for any purpose (including,
without limitation, the payment of the principal of (or premium, if any) or interest on any Debt
Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have
full power and authority to receive such money and to apply the same to the purposes for which they
were received, and shall not be affected by any notice to the contrary that may be received by it
within two Business Days prior to such date.

          The Trustee, subject to the provisions of Article VI of this Indenture, shall be entitled to
conclusively rely on the delivery to it of a written notice by a Person representing himself or
herself to be a holder of Senior Indebtedness of the Company (or a trustee or representative on
behalf of such holder) to establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee or representative on behalf of any such holder or holders. In the event
that the Trustee determines in good faith that further evidence is required with respect to the
right of any Person as a holder of such Senior Indebtedness to participate in any payment or
distribution pursuant to this Article XV, the Trustee may request such Person to furnish evidence
to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by
such Person, the extent to which such Person is entitled to participate in such payment or
distribution and any other facts pertinent to the rights of such Person under this Article XV, and,
if such evidence is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

          Section 15.07. Rights of the Trustee; Holders of Senior Indebtedness.

          The Trustee in its individual capacity shall be entitled to all the rights set forth in this
Article XV in respect of any Senior Indebtedness at any time held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in this Indenture or any Additional Provisions
shall deprive the Trustee of any of its rights as such holder.

          With respect to the holders of Senior Indebtedness of the Company, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are specifically set forth in
this Article XV, and no implied covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture or any Additional Provisions against the Trustee.
The Trustee shall not owe or be deemed to owe any fiduciary duty to the holders of such Senior
Indebtedness and, subject to the provisions of Article VI of this Indenture, the Trustee shall not
be liable to any holder of such Senior Indebtedness if it shall pay over or deliver to
Securityholders, the Company or any other Person money or assets to which any holder of such Senior
Indebtedness shall be entitled by virtue of this Article XV or otherwise.

          Nothing in this Article XV shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 6.06.

          Section 15.08. Subordination May Not Be Impaired.

          No right of any present or future holder of any Senior Indebtedness of the Company to enforce
subordination as herein provided shall at any time in any way be prejudiced or impaired by any act
or failure to act on the part of the Company, or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company, with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof that any such holder may have or otherwise
be charged with.

          Without in any way limiting the generality of the foregoing paragraph, the holders of Senior
Indebtedness of the Company may, at any time and from time to time, without the consent of or
notice to the Trustee or the Securityholders, without incurring responsibility to the
Securityholders and without impairing or releasing the subordination provided in this Article XV or
the obligations hereunder of the holders of the Debt Securities to the holders of such Senior
Indebtedness, do any one or more of the following: (a) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter, such Senior Indebtedness, or otherwise amend
or supplement in any manner such Senior Indebtedness or any instrument evidencing the same or any
agreement under which such Senior Indebtedness is outstanding; (b) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing such Senior Indebtedness;
(c) release any Person liable in any manner for the collection of such Senior Indebtedness; and (d)
exercise or refrain from exercising any rights against the Company, and any other Person.

          Wilmington Trust Company, in its capacity as Trustee, hereby accepts the trusts in this
Indenture declared and provided, upon the terms and conditions herein above set forth.

Fixed/Floating Rate Junior Subordinated Debt Security due 2036

of

MERCANTILE BANCORP, INC.

          Mercantile Bancorp, Inc., a bank holding company incorporated in Delaware (the “Company”), for
value received promises to pay to Wilmington Trust Company, not in its individual capacity but
solely as Institutional Trustee for Mercantile Bancorp Capital Trust III, a Delaware statutory
trust (the “Holder”), or registered assigns, the principal sum of TEN MILLION THREE HUNDRED TEN
THOUSAND Dollars ($10,310,000) on September 23, 2036 and to pay interest on said principal sum from
July 13, 2006, or from the most recent interest payment date (each such date, an “Interest Payment
Date”) to which interest has been paid or duly provided for, quarterly (subject to deferral as set
forth herein) in arrears on March 23, June 23, September 23 and December 23 of each year commencing
September 23, 2006, at a fixed per annum rate of interest equal to 7.17% through the end of the
Fixed Period (as defined in the Indenture) and a variable per annum rate of interest equal to LIBOR
(as defined in the Indenture), as determined on the LIBOR Determination Date (as defined in the
Indenture) for such Interest Period (as defined in the Indenture), plus 1.53% for each Interest
Period thereafter (collectively, the “Interest Rate”) until the principal hereof shall have become
due and payable, and on any overdue principal and (without duplication and to the extent that
payment of such interest is enforceable under applicable law) on any overdue installment of
interest at an annual rate equal to the Interest Rate in effect for each such Extension Period
compounded quarterly. Notwithstanding anything to the contrary contained herein, if any Interest
Payment Date, other than the Maturity Date, any Redemption Date or the Special Redemption Date,
falls on a day that is not a Business Day, then any interest payable will be paid on, and such
Interest Payment Date will be moved to, the next succeeding Business Day. During the Fixed Period,
no additional interest will accrue for each day that such payment is delayed as a result thereof.
Thereafter, additional interest will accrue for each day that such payment is delayed as a result
thereof. If the Maturity Date, any Redemption Date or the Special Redemption Date falls on a day
that is not a Business Day, then the principal, premium, if any, and/or interest payable on such
date will be paid on the next succeeding Business Day, and no additional interest will accrue in
respect of such payment made on such next succeeding Business Day. The interest installment so
payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided
in the Indenture, be paid to the Person in whose name this Debt Security (or one or more
Predecessor Securities, as defined in said Indenture) is registered at the close of business on the
regular record date for such interest installment, except that interest and any Deferred Interest
payable on the Maturity Date shall be paid to the Person to whom principal is paid. Any such
interest installment not punctually paid or duly provided for shall forthwith cease to be payable
to the registered holders on such regular record date and may be paid to the Person in whose name
this Debt Security (or one or more Predecessor Debt Securities) is registered at the close of
business on a special record date to be fixed by the Trustee for the payment of such defaulted
interest, notice whereof shall be given to the registered holders of the Debt Securities not less
than 10 days prior to such special record date, all as more fully provided in the Indenture. The
principal of and interest on this Debt Security shall be payable at the office or agency of the
Trustee (or other paying agent appointed by the Company) maintained for that purpose in any coin or
currency of the United States of America that at the time of payment is legal tender for payment

A-1-3

 

of public and private debts; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the registered holder at such address as shall
appear in the Debt Security Register or by wire transfer to an account appropriately designated by
the holder hereof. Notwithstanding the foregoing, so long as the holder of this Debt Security is
the Institutional Trustee, the payment of the principal of and interest on this Debt Security will
be made in immediately available funds at such place and to such account as may be designated by
the Trustee.

          So long as no Event of Default pursuant to Sections 5.01(b), (e) or (f) of the Indenture has
occurred and is continuing, the Company shall have the right, from time to time and without causing
an Event of Default, to defer payments of interest on the Debt Securities by extending the interest
payment period on the Debt Securities at any time and from time to time during the term of the Debt
Securities, for up to 20 consecutive quarterly periods (each such extended interest payment period,
an “Extension Period”), during which Extension Period no interest shall be due and payable (except
any Additional Interest that may be due and payable). During any Extension Period, interest will
continue to accrue on the Debt Securities, and interest on such accrued interest (such accrued
interest and interest thereon referred to herein as “Deferred Interest”) will accrue, at the
Interest Rate, compounded quarterly from the date such Deferred Interest would have been payable
were it not for the Extension Period, both to the extent permitted by law. No Extension Period may
end on a date other than an Interest Payment Date. At the end of any such Extension Period the
Company shall pay all Deferred Interest then accrued and unpaid on the Debt Securities;
provided, however, that no Extension Period may extend beyond the Maturity Date,
Redemption Date or Special Redemption Date and provided, further, however,
during any such Extension Period, the Company may not (A) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any
of the Company’s capital stock, (B) make any payment on or repay, repurchase or redeem any debt
securities of the Company that rank pari passu in all respects with or junior in interest to the
Debt Securities or (C) make any payment under any guarantees of the Company that rank pari passu in
all respects with or junior in interest to the Capital Securities Guarantee (other than (a)
repurchases, redemptions or other acquisitions of shares of capital stock of the Company (I) in
connection with any employment contract, benefit plan or other similar arrangement with or for the
benefit of one or more employees, officers, directors or consultants, (II) in connection with a
dividend reinvestment or stockholder stock purchase plan or (III) in connection with the issuance
of capital stock of the Company (or securities convertible into or exercisable for such capital
stock) as consideration in an acquisition transaction entered into prior to the occurrence of (I),
(II) or (III) above, (b) as a result of any exchange or conversion of any class or series of the
Company’s capital stock (or any capital stock of a subsidiary of the Company) for any class or
series of the Company’s capital stock or of any class or series of the Company’s indebtedness for
any class or series of the Company’s capital stock, (c) the purchase of fractional interests in
shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such
capital stock or the security being converted or exchanged, (d) any declaration of a dividend in
connection with any stockholder’s rights plan, or the issuance of rights, stock or other property
under any stockholder’s rights plan, or the redemption or repurchase of rights pursuant thereto or
(e) any dividend in the form of stock, warrants, options or other rights where the dividend stock
or the stock issuable upon exercise of such warrants, options or other rights is the same stock as
that on which the dividend is being paid or ranks pari passu with or junior in interest to such
stock). Prior to the termination of any

A-1-4

 

Extension Period, the Company may further extend such period, provided, that such period
together with all such previous and further consecutive extensions thereof shall not exceed 20
consecutive quarterly periods, or extend beyond the Maturity Date. Upon the termination of any
Extension Period and upon the payment of all Deferred Interest, the Company may commence a new
Extension Period, subject to the foregoing requirements. No interest or Deferred Interest shall be
due and payable during an Extension Period, except at the end thereof, but interest shall accrue
upon each installment of interest that would otherwise have been due and payable during such
Extension Period until such installment is paid. The Company must give the Trustee notice of its
election to begin such Extension Period at least one Business Day prior to the date such interest
is payable, but in any event not later than the related regular record date.

          The indebtedness evidenced by this Debt Security is, to the extent provided in the Indenture,
subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness,
and this Debt Security is issued subject to the provisions of the Indenture with respect thereto.
Each holder of this Debt Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on such holder’s behalf to take such action as
may be necessary or appropriate to acknowledge or effectuate the subordination so provided and (c)
appoints the Trustee such holder’s attorney-in-fact for any and all such purposes. Each holder
hereof, by such holder’s acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder of Senior
Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such
holder upon said provisions.

          The Company waives demand, presentment for payment, notice of nonpayment, notice of protest,
and all other notices.

          This Debt Security shall not be entitled to any benefit under the Indenture hereinafter
referred to and shall not be valid or become obligatory for any purpose until the certificate
of authentication hereon shall have been signed by or on behalf of the Trustee.

          The provisions of this Debt Security are continued on the reverse side hereof and such
continued provisions shall for all purposes have the same effect as though fully set forth at this
place.

          This Debt Security may contain more than one counterpart of the signature page and this Debt
Security may be executed and authenticated by the affixing of the signature of a proper officer of
the Company, and the signature of the Trustee providing authentication, to any of such counterpart
signature pages. All of such counterpart signature pages shall be read as though one, and they
shall have the same force and effect as though the Company had executed, and the Trustee had
authenticated, a single signature page.

[FORM OF REVERSE OF SECURITY]

          This Debt Security is one of a duly authorized series of Debt Securities of the Company, all
issued or to be issued pursuant to an Indenture (the “Indenture”), dated as of July 13, 2006, duly
executed and delivered between the Company and Wilmington Trust Company, as Trustee (the
“Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for
a description of the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the holders of the Debt Securities (referred to herein as the “Debt
Securities”) of which this Debt Security is a part. The summary of the terms of this Debt Security
contained herein does not purport to be complete and is qualified by reference to the Indenture.

          Upon the occurrence and continuation of a Tax Event, an Investment Company Event or a Capital
Treatment Event, this Debt Security may become due and payable, in whole but not in part, at any
time, within 90 days following the occurrence of such Tax Event, Investment Company Event or
Capital Treatment Event (the “Special Redemption Date”), as the case may be, at the Special
Redemption Price. The Company shall also have the right to redeem this Debt Security at the option
of the Company, in whole or in part, on any March 23, June 23, September 23 and December 23 on or
after September 23, 2011 (a “Redemption Date”), at the Redemption Price.

          Any redemption pursuant to the preceding paragraph will be made, subject to the receipt by the
Company of prior approval from the Board of Governors of the Federal Reserve System (the “Federal
Reserve”) if then required under applicable capital guidelines or policies of the Federal Reserve,
upon not less than 30 days’ nor more than 60 days’ notice. If the Debt Securities are only
partially redeemed by the Company, the Debt Securities will be redeemed pro rata or by lot
or by any other method utilized by the Trustee.

          “Redemption Price” means 100% of the principal amount of the Debt Securities being redeemed
plus accrued and unpaid interest on such Debt Securities to the Redemption Date or, in the case of
a redemption due to the occurrence of a Special Event, to the Special Redemption Date if such
Special Redemption Date is on or after September 23, 2011.

          “Special Redemption Price” means, with respect to the redemption of any Debt Security
following a Special Event, an amount in cash equal to the percentage for the principal amount of
the Debt Securities that is specified below for the Special Redemption Date plus unpaid interest
accrued thereon to the Special Redemption Date:

	 	 	 
	Special Event Redemption During	 	 
	Period Beginning On	 	Percentage of Principal Amount
	July 13, 2006
	 	102.20
	September 23, 2007

	September 23, 2010
	 	100.44
	September 23, 2011
	 	100.00

A-1-6

 

          In the event of redemption of this Debt Security in part only, a new Debt Security or Debt
Securities for the unredeemed portion hereof will be issued in the name of the holder hereof upon
the cancellation hereof.

          In case an Event of Default, as defined in the Indenture, shall have occurred and be
continuing, the principal of all of the Debt Securities may be declared due and payable, and upon
such declaration of acceleration shall become due and payable, in the manner, with the effect and
subject to the conditions provided in the Indenture.

          The Indenture contains provisions permitting the Company and the Trustee, with the consent of
the holders of not less than a majority in aggregate principal amount of the Debt Securities at the
time outstanding affected thereby, as specified in the Indenture, to execute supplemental
indentures for the purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner
the rights of the holders of the Debt Securities; provided, however, that no such
supplemental indenture shall, among other things, without the consent of the holders of each Debt
Security then outstanding and affected thereby (i) extend the fixed maturity of the Debt
Securities, or reduce the principal amount thereof or any redemption premium thereon, or reduce the
rate or extend the time of payment of interest thereon, or make payments due on the Debt Securities
payable in any coin or currency other than that provided in the Debt Securities, or impair or
affect the right of any holder of Debt Securities to institute suit for the payment thereof, or
(ii) reduce the aforesaid percentage of Debt Securities, the holders of which are required to
consent to any such supplemental indenture. The Indenture also contains provisions permitting the
holders of a majority in aggregate principal amount of the Debt Securities at the time outstanding,
on behalf of all of the holders of the Debt Securities, to waive any past default in the
performance of any of the covenants contained in the Indenture, or established pursuant to the
Indenture, and its consequences, except a default in payments due on any of the Debt Securities.
Any such consent or waiver by the registered holder of this Debt Security (unless revoked as
provided in the Indenture) shall be conclusive and binding upon such holder and upon all future
holders and owners of this Debt Security and of any Debt Security issued in exchange herefor or in
place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any
notation of such consent or waiver is made upon this Debt Security.

          No reference herein to the Indenture and no provision of this Debt Security or of the
Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional,
to pay all payments due on this Debt Security at the time and place and at the rate and in the
money herein prescribed.

          As provided in the Indenture and subject to certain limitations herein and therein set forth,
this Debt Security is transferable by the registered holder hereof on the Debt Security Register of
the Company, upon surrender of this Debt Security for registration of transfer at the office or
agency of the Trustee in Wilmington, Delaware accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company or the Trustee duly executed by the registered holder
hereof or such holder’s attorney duly authorized in writing, and thereupon one or more new Debt
Securities of authorized denominations and for the same aggregate principal

A-1-7

 

amount will be issued to the designated transferee or transferees. No service charge will be
made for any such registration of transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation thereto.

          Prior to due presentment for registration of transfer of this Debt Security, the Company, the
Trustee, any Authenticating Agent, any Paying Agent, any transfer agent and the Debt Security
registrar may deem and treat the registered holder hereof as the absolute owner hereof (whether or
not this Debt Security shall be overdue and notwithstanding any notice of ownership or writing
hereon) for the purpose of receiving payment of or on account of the principal hereof, premium, if
any, and interest due hereon and for all other purposes, and neither the Company nor the Trustee
nor any Authenticating Agent nor any Paying Agent nor any transfer agent nor any Debt Security
registrar shall be affected by any notice to the contrary.

          No recourse shall be had for the payment of the principal of or premium, if any, or the
interest on this Debt Security, or for any claim based hereon, or otherwise in respect hereof, or
based on or in respect of the Indenture, against any incorporator, stockholder, officer or
director, past, present or future, as such, of the Company or of any predecessor or successor
corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement
of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and
as part of the consideration for the issuance hereof, expressly waived and released.

          The Debt Securities are issuable only in registered certificated form without coupons. As
provided in the Indenture and subject to certain limitations herein and therein set forth, Debt
Securities are exchangeable for a like aggregate principal amount of Debt Securities of a different
authorized denomination, as requested by the holder surrendering the same.

          All terms used in this Debt Security that are defined in the Indenture shall have the meanings
assigned to them in the Indenture.

          THE LAW OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THE DEBT SECURITIES,
WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES THEREOF.

the Securities are to be authenticated, issued and delivered; and

     Whereas, all things necessary to make this Indenture a valid agreement of the
Company, in accordance with its terms, have been done.

the Securities, the payment of which has not been made on the applicable Interest Payment Date and
which shall accrue at the rate per annum, compounded quarterly, specified or determined as
specified in such Security.

     “Additional Tax Sums” has the meaning specified in Section 10.5.

     “Additional Taxes” means taxes, duties or other governmental charges imposed on the Trust as a
result of a Tax Event (which, for the sake of clarity, does not include amounts required to be

Holder of, or any Person that acquires a beneficial interest in, the Securities).

     “Administrative Trustee” means, with respect to the Trust, a Person identified as an
“Administrative Trustee” in the Trust Agreement, solely in its capacity as Administrative Trustee
of the Trust under the Trust Agreement and not in its individual capacity, or its successor in
interest in such capacity, or any successor Administrative Trustee appointed as therein provided.

     “Affiliate” of any specified Person means any other Person directly or indirectly controlling
or controlled by or under direct or indirect common control with such specified Person. For the
purposes of this definition, “control,” when used with respect to any specified Person, means the

experienced in such matters that, as a result of an amendment to or a change in law, rule or

regulatory authority, there is more than an insubstantial risk that within ninety (90) days of the
date of such opinion, the aggregate liquidation amount of the Preferred Securities will not be
eligible to be treated by the Company as “Tier 1 Capital” (or the then equivalent) for purposes of
the capital adequacy guidelines of the Federal Reserve or other “appropriate Federal banking
agency” as such term is defined in 12 U.S.C. 1813(q), which amendment, change or prospective change
becomes effective or would become effective, as the case may be, on or after the date of issuance
of the Securities; provided, however, that the inability of the Company to treat all or any portion
of the liquidation amount of the Preferred Securities as Tier 1 Capital shall not constitute the
basis for a Capital Disqualification Event if such inability results from the Company having such
Preferred Securities outstanding in an amount that for any reason is in excess of the amount which
may now or hereafter qualify for treatment as Tier 1 Capital under applicable capital adequacy
guidelines. By way of example, the inability of the Company to treat all or any portion of the
liquidation amount of the Preferred Securities as Tier 1 Capital as a result of the Final Rule on
Risk-Based Capital Standards: Trust Preferred Securities and the Definition of Capital, adopted on

execution and/or delivery thereof, such substitute document or instrument shall be deemed to have
been executed and/or delivered as of the date or dates required with respect to the document or
instrument for which it is substituted. Without limiting the generality of the foregoing, any
Securities issued under the authority of such defective document or instrument shall nevertheless
be the valid obligations of the Company entitled to the benefits of this Indenture equally and
ratably with all other Outstanding Securities.

     SECTION 1.4. Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by an agent
thereof duly appointed in writing; and, except as herein otherwise expressly provided, such action
shall become effective when such instrument or instruments (including any appointment of an agent)
is or are delivered to the Trustee, and, where it is hereby expressly required, to the Company.
Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall be sufficient for
any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in
the manner provided in this Section 1.4.

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

     (c) The ownership of Securities shall be proved by the Securities Register.

     (d) Any request, demand, authorization, direction, notice, consent, waiver or other action 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 or the Company in
reliance thereon, whether or not notation of such action is made upon such Security.

     (e) Without limiting the foregoing, a Holder entitled to take any action hereunder with regard
to any particular Security may do so with regard to all or any part of the principal

12

 

amount of such Security or by one or more duly appointed agents each of which may do so
pursuant to such appointment with regard to all or any part of such principal amount.

     (f) Except as set forth in paragraph (g) of this Section 1.4, the Company may set any
day as a record date for the purpose of determining the Holders of Outstanding Securities entitled
to give, make or take any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken by Holders of
Securities. If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to take the relevant
action, whether or not such Holders remain Holders after such record date; provided, that no such
action shall be effective hereunder unless taken on or prior to the applicable Expiration Date (as
defined below) by Holders of the requisite principal amount of Outstanding Securities on such
record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new
record date for any action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with no action by any
Person be canceled and of no effect). Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to
each Holder of Securities in the manner set forth in Section 1.6.

     (g) The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities entitled to join in the giving or making of (i) any Notice of Default, (ii)
any declaration of acceleration or rescission or annulment thereof referred to in Section
5.2, (iii) any request to institute proceedings referred to in Section 5.7(b) or (iv)
any direction referred to in Section 5.12. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Securities on such record date, and no other Holders, shall
be entitled to join in such notice, declaration, request or direction, whether or not such Holders
remain Holders after such record date; provided, that no such action shall be effective hereunder
unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities on such record date. Nothing in this paragraph shall be construed
to prevent the Trustee from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect). Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause
notice of such record date, the proposed action by Holders and the applicable Expiration Date to be
given to the Company in writing and to each Holder of Securities in the manner set forth in
Section 1.6.

     (h) With respect to any record date set pursuant to paragraph (f) or (g) of this
Section 1.4, the party hereto that sets such record date may designate any day as the
“Expiration Date” and from time to time may change the Expiration Date to any earlier or later day;
provided, that no such change shall be effective unless notice of the proposed new Expiration Date
is given to the other party hereto in writing, and to each Holder of Securities in the manner set
forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date is
not designated with respect to any record date set pursuant to this Section 1.4, the party
hereto that set such record date shall be deemed to have initially designated the ninetieth
(90th) day after such record date as the Expiration Date with respect thereto, subject
to its right to change the Expiration Date

13

 

as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later
than the one hundred and eightieth (180th) day after the applicable record date.

     SECTION 1.5. Notices, Etc.

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

     (a) the Trustee by any Holder, any holder of Preferred Securities or the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the
Trustee at its Corporate Trust Office,

     (b) the Company by the Trustee, any Holder or any holder of Preferred Securities shall be
sufficient for every purpose hereunder if in writing and mailed, first class, postage prepaid, to
the Company addressed to it at 440 Maine Street, Quincy, Illinois 62301, Attn: Chief Financial
Officer, or at any other address previously furnished in writing to the Trustee by the Company, or

     (c) the Purchaser by the Trustee, the Company, any Holder or any holder or beneficial owner of
the Preferred Securities, shall be sufficient for every purpose hereunder if in writing and mailed

Queensgate House, South Church Street, George Town, Grand Cayman, Cayman Islands, Attention: The
Directors, or any other address previously furnished by the Purchaser.

     SECTION 1.6. Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first
class, postage prepaid, to each Holder affected by such event to the address of such Holder as it
appears in the Securities Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. If, by reason of the suspension of or
irregularities in regular mail service or for any other reason, it shall be impossible or
impracticable to mail notice of any event to Holders when said notice is required to be given
pursuant to any provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect
in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either before or after the
event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall
be filed with the Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

     SECTION 1.9. Separability Clause.

     If any provision in this Indenture or in the Securities shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby, and there shall be deemed substituted for the provision at
issue a valid, legal and enforceable provision as similar as possible to the provision at issue.

Date in October, 2017, and a variable rate, per annum, reset quarterly, equal to LIBOR plus 1.58%
thereafter, compounded quarterly, from the dates such amounts are due until they are paid or funds
for the payment thereof are made available for payment.

     (b) Interest and Additional Interest on any Security that is payable, and is punctually paid
or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest, except that interest and any Additional Interest payable on
the Stated Maturity (or any date of principal repayment upon early maturity) of the principal of a
Security or on a Redemption Date shall be paid to the Person to whom principal is paid. The initial
payment of interest on any Security that is issued between a Regular Record Date and the related
Interest Payment Date shall be payable as provided in such Security.

17

 

     (c) Any interest on any Security that is due and payable, but is not timely paid or duly
provided for, on any Interest Payment Date for Securities (herein called “Defaulted Interest”)
shall forthwith cease to be payable to the registered Holder 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 paragraph (i) or (ii) below:

     (i) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities (or their respective Predecessor Securities) are
registered at the close of business on a special record date for the payment of such
Defaulted Interest (a “Special Record Date”), which shall be fixed in the following manner.
At least thirty (30) days prior to the date of the proposed payment, the Company shall
notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each 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 prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such Defaulted
Interest. Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest, which shall be not more than fifteen (15) days and not less than ten
(10) days prior to the date of the proposed payment and not less than ten (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 each Holder of a
Security at the address of such Holder as it appears in the Securities Register not less
than ten (10) days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so mailed, such
Defaulted Interest shall be paid to the Persons in whose names the Securities (or their
respective Predecessor Securities) are registered on such Special Record Date; or

     (ii) The Company may make payment of any Defaulted Interest in any other lawful
manner not inconsistent with the requirements of any securities exchange or automated
quotation system on which the Securities may be listed, traded or quoted and, upon such
notice as may be required by such exchange or automated quotation system (or by the Trustee
if the Securities are not listed), 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.

     (d) Payments of interest on the Securities shall include interest accrued to but excluding the
respective Interest Payment Dates. The amount of interest payable for any interest period shall be
computed and paid on the basis of a 360-day year and the actual number of days elapsed in the
relevant interest period.

     (e) Payment of principal of, premium, if any, and interest on the Securities shall be made in
such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts. Payments of principal, premium, if any, and

18

 

interest due at the Maturity of such Securities shall be made at the Place of Payment upon
surrender of such Securities to the Paying Agent and payments of interest shall be made subject to
such surrender where applicable, by wire transfer at such place and to such account at a banking
institution in the United States as may be designated in writing to the Paying Agent at least ten
(10) Business Days prior to the date for payment by the Person entitled thereto unless proper
written wire transfer instructions have not been received by the relevant record date, in which
case such payments shall be made by check mailed to the address of such Person as such address
shall appear in the Security Register. Notwithstanding the foregoing, so long as the holder of the
Security is the Property Trustee, the payment of the principal of (and premium if any) and interest
(including any overdue installment of interest and Additional Tax Sums, if any) on the Security
will be made at such place and to such account as may be designated by the Property Trustee.

     (f) Subject to the foregoing provisions of this Section 3.1, each Security
delivered under this Indenture upon 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, that were carried by such
other Security.

     SECTION 3.2. Denominations.

     The Securities shall be in registered form without coupons and shall be issuable in
minimum denominations of $100,000 and any integral multiple of $1,000 in excess thereof.

     SECTION 3.3. Execution, Authentication, Delivery and Dating.

     (a) At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities in an aggregate principal amount (including all
then Outstanding Securities) not in excess of $20,619,000 executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication and delivery
of such Securities, and the Trustee in accordance with the Company Order 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
entitled to
receive, and shall be fully protected in relying upon:

     (i) a copy of any Board Resolution relating thereto; and

     (ii) an Opinion of Counsel stating that (1) 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, 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; (2) the Securities have been
duly authorized and executed by the Company and have been delivered to the Trustee for
authentication in accordance with this Indenture; and (3) the Securities are not required to
be registered under the Securities Act.

     (b) The Securities shall be executed on behalf of the Company by its Chairman of the
Board, its Vice Chairman of the Board, its Chief Executive Officer, its President or one of
its

19

 

Vice Presidents. The signature of any of these officers on the Securities may be manual or
facsimile. Securities bearing the manual or facsimile signatures of individuals who were at any
time the proper officers of the Company 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.

     (c) 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 herein executed by the Trustee by the manual signature
of one of its authorized officers, and 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 3.8, 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.

     (d) Each Security shall be dated the date of its authentication.

     SECTION 3.4. Global Securities.

     (a) Upon the election of the Holder after the Original Issue Date, which election need not be
in writing, the Securities owned by such Holder shall be issued in the form of one or more Global
Securities registered in the name of the Depositary or its nominee. Each Global Security issued
under this Indenture shall be registered in the name of the Depositary designated by the Company
for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof
or custodian therefor, and each such Global Security shall constitute a single Security for all
purposes of this Indenture.

     (b) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged
in whole or in part for registered Securities, and no transfer of a Global Security in whole or in
part may be registered, in the name of any Person other than the Depositary for such Global
Security or a nominee thereof unless (i) such Depositary advises the Trustee and the Company in
writing that such Depositary is no longer willing or able to properly discharge its
responsibilities as Depositary with respect to such Global Security, and no qualified successor is
appointed by the Company within ninety (90) days of receipt by the Company of such notice, (ii)
such Depositary ceases to be a clearing agency registered under the Exchange Act and no successor
is appointed by the Company within ninety (90) days after obtaining knowledge of such event, (iii)
the Company executes and delivers to the Trustee a Company Order stating that the Company elects to
terminate the book-entry system through the Depositary or (iv) an Event of Default shall have
occurred and be continuing. Upon the occurrence of any event specified in clause (i), (ii), (iii)
or (iv) above, the Trustee shall notify the Depositary and instruct the Depositary to notify all
owners of beneficial interests in such Global Security of the occurrence of such event and of the
availability of Securities to such owners of beneficial interests requesting the same. Upon the
issuance of such Securities and the registration in the Securities Register of such Securities in
the names of the Holders of the beneficial interests therein, the Trustees shall recognize such
holders of beneficial interests as Holders.

20

 

     (c) If any Global Security is to be exchanged for other Securities or canceled in part, or if
another Security is to be exchanged in whole or in part for a beneficial interest in any Global
Security, then either (i) such Global Security shall be so surrendered for exchange or cancellation
as provided in this Article III or (ii) the principal amount thereof shall be reduced or
increased by an amount equal to the portion thereof to be so exchanged or canceled, or equal to the
principal amount of such other Security to be so exchanged for a beneficial interest therein, as
the case may be, by means of an appropriate adjustment made on the records of the Securities
Registrar, whereupon the Trustee, in accordance with the Applicable Depositary Procedures, shall
instruct the Depositary or its authorized representative to make a corresponding adjustment to its
records. Upon any such surrender or adjustment of a Global Security by the Depositary, accompanied
by registration instructions, the Company shall execute and the Trustee shall authenticate and
deliver any Securities issuable in exchange for such Global Security (or any portion thereof) in
accordance with the instructions of the Depositary. The Trustee shall not be liable for any delay
in delivery of such instructions and may conclusively rely on, and shall be fully protected in
relying on, such instructions.

     (d) Every Security authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Security or any portion thereof shall be authenticated and
delivered in the form of, and shall be, a Global Security, unless such Security is registered in
the name of a Person other than the Depositary for such Global Security or a nominee thereof.

     (e) Securities distributed to holders of Book-Entry Preferred Securities (as defined in the
Trust Agreement) upon the dissolution of the Trust shall be distributed in the form of one or more
Global Securities registered in the name of a Depositary or its nominee, and deposited with the
Securities Registrar, as custodian for such Depositary, or with such Depositary, for credit by the
Depositary to the respective accounts of the beneficial owners of the Securities represented
thereby (or such other accounts as they may direct). Securities distributed to holders of Preferred
Securities other than Book-Entry Preferred Securities upon the dissolution of the Trust shall not
be issued in the form of a Global Security or any other form intended to facilitate book-entry
trading in beneficial interests in such Securities.

     (f) The Depositary or its nominee, as the registered owner of a Global Security, shall be the
Holder of such Global Security for all purposes under this Indenture and the Securities, and owners
of beneficial interests in a Global Security shall hold such interests pursuant to the Applicable
Depositary Procedures. Accordingly, any such owner’s beneficial interest in a Global Security shall
be shown only on, and the transfer of such interest shall be effected only through, records
maintained by the Depositary or its nominee or its Depositary Participants. The Securities
Registrar and the Trustee shall be entitled to deal with the Depositary for all purposes of this
Indenture relating to a Global Security (including the payment of principal and interest thereon
and the giving of instructions or directions by owners of beneficial interests therein and the
giving of notices) as the sole Holder of the Security and shall have no obligations to the owners
of beneficial interests therein. Neither the Trustee nor the Securities Registrar shall have any
liability in respect of any transfers effected by the Depositary.

     (g) The rights of owners of beneficial interests in a Global Security shall be exercised only
through the Depositary and shall be limited to those established by law and agreements between such
owners and the Depositary and/or its Depositary Participants.

21

 

     (h) 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, the
Trustee nor any agent of the Company or the Trustee 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 maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written
certification, proxy or other authorization furnished by a Depositary or impair, as between a
Depositary and such holders of beneficial interests, the operation of customary practices governing
the exercise of the rights of the Depositary (or its nominee) as Holder of any Security.

     SECTION 3.5. Registration, Transfer and Exchange Generally.

     (a) The Trustee shall cause to be kept at the Corporate Trust Office a register (the
“Securities Register”) in which the registrar and transfer agent with respect to the Securities
(the “Securities Registrar”), subject to such reasonable regulations as it may prescribe, shall
provide for the registration of Securities and of transfers and exchanges of Securities. The
Trustee shall at all times also be the Securities Registrar. The provisions of Article VI
shall apply to the Trustee in its role as Securities Registrar.

     (b) Subject to compliance with Section 2.2(b), upon surrender for registration of
transfer of any Security at the offices or agencies of the Company designated for that purpose the
Company shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of any authorized denominations of
like tenor and aggregate principal amount.

     (c) At the option of the Holder, Securities may be exchanged for other Securities of any
authorized denominations, of like tenor and aggregate principal amount, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for
exchange, the Company shall execute, and upon receipt thereof the Trustee shall authenticate and
deliver, the Securities that the Holder making the exchange is entitled to receive.

     (d) All Securities issued upon any transfer or exchange of Securities shall be the valid
obligations of the Company, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such transfer or exchange.

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

     (f) No service charge shall be made to a Holder for any transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any tax or other

22

 

governmental charge that may be imposed in connection with any transfer or exchange of
Securities.

     (g) Neither the Company nor the Trustee shall be required pursuant to the provisions of
this Section 3.5 (i) to issue, register the transfer of or exchange any Security during a
period beginning at the opening of business fifteen (15) days before the day of selection for
redemption of Securities pursuant to Article XI and ending at the close of business on the
day of mailing of the notice of redemption or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except, in the case of any such Security
to be redeemed in part, any portion thereof not to be redeemed.

     (h) The Company shall designate an office or offices or agency or agencies where
Securities may be surrendered for registration or transfer or exchange. The Company initially
designates the Corporate Trust Office as its office and agency for such purposes. The Company shall
give prompt written notice to the Trustee and to the Holders of any change in the location of any
such office or agency.

     SECTION 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

     (a) If any mutilated Security is surrendered to the Trustee together with such security or
indemnity as may be required by the Company or the Trustee to save each of them harmless, the
Company shall execute and upon receipt thereof the Trustee shall authenticate and deliver in
exchange therefor a new Security of like tenor and aggregate principal amount and bearing a number
not contemporaneously outstanding.

     (b) If there shall 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 harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company
shall execute and upon its written request the Trustee shall authenticate and deliver, in lieu of
any such destroyed, lost or stolen Security, a new Security of like tenor and aggregate principal
amount as such destroyed, lost or stolen Security, and bearing a number not contemporaneously
outstanding.

     (c) If any such 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.

     (d) Upon the issuance of any new Security under this Section 3.6, 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.

     (e) Every new Security issued pursuant to this Section 3.6 in lieu of any mutilated,
destroyed, lost or stolen Security shall constitute an original additional contractual obligation
of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any
time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

23

 

     (f) The provisions of this Section 3.6 are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities.

     SECTION 3.7. Persons Deemed Owners.

     The Company, the Trustee and any agent of the Company or the Trustee shall treat the Person in
whose name any Security is registered as the owner of such Security for the purpose of receiving
payment of principal of and any interest on such Security and for all other purposes whatsoever,
and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected
by notice to the contrary.

     SECTION 3.8. Cancellation.

     All Securities surrendered for payment, redemption, transfer or exchange shall, if surrendered
to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and
Securities surrendered directly to the Trustee for any such purpose shall be promptly canceled by
it. 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 promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided in this Section
3.8, except as expressly permitted by this Indenture. All canceled Securities shall be disposed
of by the Trustee in accordance with its customary practices and the Trustee shall deliver to the
Company a certificate of such disposition.

     SECTION 3.9. Deferrals of Interest Payment Dates.

     (a) So long as no Event of Default pursuant to Sections 5.1(c), (e),
(f), (g) or (h) has occurred and is continuing, the Company shall have the
right, at any time and from time to time during the term of the Security, to defer the payment of
interest on the Securities for a period of up to twenty (20) consecutive quarterly interest payment
periods (each such period, an “Extension Period”), during which Extension Period(s), the Company
shall have the right to make no payments or partial payments of interest on any Interest Payment
Date (except any Additional Tax Sums that otherwise may be due and payable). No Extension Period
shall end on a date other than an Interest Payment Date and no Extension Period shall extend beyond
the Stated Maturity of the principal of the Securities. No interest shall be due and payable during
an Extension Period, except at the end thereof, but each installment of interest that would
otherwise have been due and payable during such Extension Period shall bear Additional Interest (to
the extent payment of such interest would be legally enforceable) at a fixed rate per annum equal
to 6.84% through the interest payment date in October, 2017, and a variable rate, per annum, reset
quarterly, equal to LIBOR plus 1.58% thereafter, compounded quarterly, from the dates on which
amounts would have otherwise been due and payable until paid or until funds for the payment thereof
have been made available for payment. At the end of any such Extension Period, the Company shall
pay all interest then accrued and unpaid on the Securities together with such Additional Interest.
Prior to the termination of any such Extension Period, the Company may extend such Extension Period
and further defer the payment of interest; provided, that (i) all such previous and further
extensions comprising such Extension Period do not exceed

24

 

twenty (20) quarterly interest payment periods, (ii) no Extension Period shall end on a date other
than an Interest Payment Date and (iii) no Extension Period shall extend beyond the Stated Maturity
of the principal of the Securities. Upon the termination of any such Extension Period and upon the
payment of all accrued and unpaid interest and any Additional Interest then due on any Interest
Payment Date, the Company may elect to begin a new Extension Period; provided, that (i) such
Extension Period does not exceed twenty (20) quarterly interest payment periods, (ii) no Extension
Period shall end on a date other than an Interest Payment Date, (iii) no Extension Period shall
extend beyond the Stated Maturity of the principal of the Securities and (iv) no Event of Default
pursuant to Sections 5.1(c), (e), (f), (g) or (h) has
occurred and is continuing. The Company shall give (i) the Holders of the Securities, (ii) the
Trustee, (iii) the Property Trustee and (iv) any beneficial owner of the Preferred Securities
reasonably identified to the Company (which identification may be made either by such beneficial
owner or by the Purchaser) written notice of its election to begin any such Extension Period no
later than the close of business on the fifteenth (15th) Business Day prior to the next succeeding
Interest Payment Date on which interest on the Securities would be payable but for such deferral.

     (b) In connection with any such Extension Period, the Company shall be subject to the
restrictions set forth in Section 10.6(a).

     SECTION 3.10. Right of Set-Off.

     Notwithstanding anything to the contrary herein, the Company shall have the right to set off
any payment it is otherwise required to make in respect of any Security to the extent the Company
has theretofore made, or is concurrently on the date of such payment making, a payment under the
Guarantee Agreement relating to such Security or to a holder of Preferred Securities pursuant to an
action undertaken under Section 5.8 of this Indenture.

     SECTION 3.11. Agreed Tax Treatment.

     Each Security issued hereunder shall provide that the Company and, by its acceptance or
acquisition of a Security or a beneficial interest therein, the Holder of, and any Person that
acquires a direct or indirect beneficial interest in, such Security, intend and agree to treat such
Security as indebtedness of the Company for United States Federal, state and local tax purposes and
to treat the Preferred Securities (including but not limited to all payments and proceeds with
respect to the Preferred Securities) as an undivided beneficial ownership interest in the Trust
(and payments and proceeds therefrom, respectively) for United States Federal, state and local tax
purposes. The provisions of this Indenture shall be interpreted to further this intention and
agreement of the parties.

     SECTION 3.12. CUSIP Numbers.

     The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and,
if so, the Trustee shall use “CUSIP” numbers in notices of redemption and other similar or related
materials as a convenience to Holders; provided, that any such notice or other materials 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 redemption or other materials and that

25

 

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.

ARTICLE IV

Satisfaction and Discharge

     SECTION 4.1. Satisfaction and Discharge of Indenture.

     This Indenture shall, upon Company Request, cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein expressly provided
for and as otherwise provided in this Section 4.1) and the Trustee, on demand of and at the
expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge
of this Indenture, when

     (a) either

     (i) all Securities theretofore authenticated and delivered (other than (A)
Securities that have been mutilated, destroyed, lost or stolen and that have been replaced
or paid as provided in Section 3.6 and (B) Securities for whose payment money has
theretofore been deposited in trust or segregated and held in trust by the Company and
thereafter repaid to the Company or discharged from such trust as provided in Section
10.2) have been delivered to the Trustee for cancellation; or

     (ii) all such Securities not theretofore delivered to the Trustee for
cancellation

	 	(A)	 	have become due and payable, or
	 
	 	(B)	 	will become due and payable at their Stated
Maturity within one year of the date of deposit, or
	 
	 	(C)	 	are to be called for redemption within one year
under arrangements satisfactory to the Trustee for the giving of notice
of redemption by the Trustee in the name, and at the expense, of the
Company,

and the Company, in the case of subclause (ii)(A), (B) or (C) above, has deposited or caused
to be deposited with the Trustee as trust funds in trust for such purpose (x) an amount in
the currency or currencies in which the Securities are payable, (y) Government Obligations
which through the scheduled payment of principal and interest in respect thereof in
accordance with their terms will provide, not later than the due date of any payment, money
in an amount or (z) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay and discharge the entire indebtedness
on such Securities not theretofore delivered to the Trustee for cancellation, for principal
and any premium and interest (including any Additional Interest) to the date of such deposit

any date of principal repayment upon early maturity) or Redemption Date, as the case may be;

26

 

     (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company;
and

     (c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel each stating that all conditions precedent herein provided for relating to the satisfaction
and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to
the Trustee under Section 6.6, the obligations of the Company to any Authenticating Agent
under Section 6.11 and, if money shall have been deposited with the Trustee pursuant to
subclause (a)(ii) of this Section 4.1, the obligations of the Trustee under Section
4.2 and Section 10.2(e) shall survive such satisfaction and discharge.

     SECTION 4.2. Application of Trust Money.

     Subject to the provisions of Section 10.2(e), all money deposited with the Trustee
pursuant to Section 4.1 shall be held in trust and applied by the Trustee, in accordance
with the provisions of the Securities and this Indenture, to the payment in accordance with
Section 3.1, either directly or through any Paying Agent (including the Company acting as
its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the
principal and any premium and interest (including any Additional Interest) for the payment of which
such money or obligations have been deposited with or received by the Trustee. Moneys held by the
Trustee under this Section 4.2 shall not be subject to the claims of holders of Senior Debt
under Article XII.

ARTICLE V

Remedies

     SECTION 5.1. Events of Default.

     “Event of Default” means, wherever used herein with respect to the Securities, any one of the
following events (whatever the reason for such Event of Default and whether it shall be voluntary
or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or governmental body):

     (a) default in the payment of any interest upon any Security, including any Additional

     (d) default in the performance, or breach, of any covenant or warranty of the Company in this
Indenture and continuance of such default or breach for a period of thirty (30) days after there
has been given, by registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least twenty five percent (25%) in aggregate principal amount
of the Outstanding Securities a written notice specifying such default or breach and requiring it
to be remedied and stating that such notice is a “Notice of Default” hereunder; or

     (e) the entry by a court having jurisdiction in the premises of a decree or order adjudging
the Company a bankrupt or insolvent, or approving as properly filed a petition seeking

or order for the appointment of a receiver of a Major Bank Subsidiary or all or substantially all
of its property in any liquidation, insolvency or similar proceeding, or (2) a Major Bank
Subsidiary shall consent to the appointment of a receiver for it or all or substantially all of its
property in any liquidation, insolvency or similar proceeding; or

     (h) the Trust shall have voluntarily or involuntarily liquidated, dissolved, wound-up its

the Securities to holders of the Preferred Securities in liquidation of their interests in the
Trust, (2) the redemption of all of the outstanding Preferred Securities or (3) certain mergers,
consolidations or amalgamations, each as and to the extent permitted by the Trust Agreement.

     SECTION 5.2. Acceleration of Maturity; Rescission and Annulment.

     (a) If an Event of Default pursuant to Sections 5.1(c), (e), (f),
(g) or (h) occurs and is continuing, then and in every such case the Trustee or the
Holders of not less than twenty five percent (25%) in aggregate principal amount of the Outstanding
Securities may declare the principal amount of all the Securities to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given by Holders),
provided, that if, upon an Event of

28

 

Default pursuant to Sections 5.1(c), (e), (f), (g) or (h),
the Trustee or the Holders of not less than twenty five percent (25%) in principal amount of the
Outstanding Securities fail to declare the principal of all the Outstanding Securities to be
immediately due and payable, the holders of at least twenty five percent (25%) in aggregate
Liquidation Amount of the Preferred Securities then outstanding shall have the right to make such
declaration by a notice in writing to the Property Trustee, the Company and the Trustee; and upon
any such declaration the principal amount of and the accrued interest (including any Additional
Interest) on all the Securities shall become immediately due and payable.

     (b) At any time after such a declaration of acceleration with respect to the Securities
has been made and before a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter provided in this Article V, the Holders of a majority in aggregate
principal amount of the Outstanding Securities, by written notice to the Trustee, or the holders of
a majority in aggregate Liquidation Amount of the Preferred Securities, by written notice to the
Property Trustee, the Company and the Trustee, may rescind and annul such declaration and its
consequences if:

     (i) the Company has paid or deposited with the Trustee a sum sufficient to pay:

	 	(A)	 	all overdue installments of interest on all Securities,
	 
	 	(B)	 	any accrued Additional Interest on all Securities,

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

     (ii) all Events of Default with respect to the Securities, other than the
nonpayment of the principal of Securities that has become due solely by such acceleration,
have been cured or waived as provided in Section 5.13;

provided, that if the Holders of such Securities fail to annul such declaration and waive such
default, the holders of not less than a majority in aggregate Liquidation Amount of the Preferred
Securities then outstanding shall also have the right to rescind and annul such declaration and its
consequences by written notice to the Property Trustee, the Company and the Trustee, subject to the
satisfaction of the conditions set forth in paragraph (b) of this Section 5.2. No such
rescission shall affect any subsequent default or impair any right consequent thereon.

29

 

     SECTION 5.3. Collection of Indebtedness and Suits for Enforcement by Trustee.

     (a) The Company covenants that if:

     (i) default is made in the payment of any installment of interest (including any
Additional Interest) on any Security when such interest becomes due and payable and such
default continues for a period of thirty (30) days, or

     (ii) default is made in the payment of the principal of and any premium on any
Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of
such Securities, the whole amount then due and payable on such Securities for principal and any
premium and interest (including any Additional Interest) and, in addition thereto, all amounts
owing the Trustee under Section 6.6.

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

     (c) If an Event of Default with respect to the Securities occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or
to enforce any other proper remedy.

     SECTION 5.4. Trustee May File Proofs of Claim.

     In case of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement,
adjustment, composition or similar judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and
empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized
hereunder in order to have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same; and any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the
event that the Trustee shall consent to the making of such payments directly to the Holders, to
first pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts owing the Trustee, any
predecessor Trustee and other Persons under Section 6.6.

30

 

     SECTION 5.5. Trustee May Enforce Claim Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may be prosecuted and
enforced by the Trustee without the possession of any of the Securities or the production thereof
in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of judgment shall,
subject to Article XII and after provision for the payment of all the amounts owing the
Trustee, any predecessor Trustee and other Persons under Section 6.6, be for the ratable
benefit of the Holders of the Securities in respect of which such judgment has been recovered.

     SECTION 5.6. Application of Money Collected.

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

     FIRST: To the payment of all amounts due the Trustee, any predecessor Trustee and other
Persons under Section 6.6;

     SECOND: To the payment of all Senior Debt of the Company if and to the extent required
by Article XII.

     THIRD: Subject to Article XII, to the payment of the amounts then due and unpaid upon
the Securities for principal and any premium and interest (including any Additional Interest) in
respect of which or for the benefit of which such money has been collected, ratably, without
preference or priority of any kind, according to the amounts due and payable on the Securities for
principal and any premium and interest (including any Additional Interest), respectively; and

     FOURTH: The balance, if any, to the Person or Persons entitled thereto.

     SECTION 5.7. Limitation on Suits.

     Subject to Section 5.8, no Holder of any Securities shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a
custodian, receiver, assignee, trustee, liquidator, sequestrator (or other similar official) or for
any other remedy hereunder, unless:

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

     (b) the Holders of not less than a majority in aggregate principal amount of the Outstanding
Securities shall have made written request to the Trustee to institute proceedings in respect of
such Event of Default in its own name as Trustee hereunder;

31

 

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

     (d) the Trustee after its receipt of such notice, request and offer of indemnity has failed to
institute any such proceeding for sixty (60) days; and

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

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

     SECTION 5.8. Unconditional Right of Holders to Receive Principal, Premium and Interest;
Direct Action by Holders of Preferred Securities.

     Notwithstanding any other provision in this Indenture, the Holder of any Security shall have
the right, which is absolute and unconditional, to receive payment of the principal of and any
premium on such Security at its Maturity and payment of interest (including any Additional
Interest) on such Security when due and payable and to institute suit for the enforcement of any
such payment, and such right shall not be impaired without the consent of such Holder. Any
registered holder of the Preferred Securities shall have the right, upon the occurrence of an Event
of Default described in Section 5.1(a), Section 5.1(b) or Section 5.1(c),
to institute a suit directly against the Company for enforcement of payment to such holder of
principal of and any premium and interest (including any Additional Interest) on the Securities
having a principal amount equal to the aggregate Liquidation Amount of the Preferred Securities
held by such holder.

     SECTION 5.9. Restoration of Rights and Remedies.

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

     SECTION 5.10. Rights and Remedies Cumulative.

     Except as otherwise provided in Section 3.6(f), no right or remedy herein conferred
upon or reserved to the Trustee or the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter existing at law or in
equity

32

 

or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not
prevent the concurrent assertion or employment of any other appropriate right or remedy.

     SECTION 5.11. Delay or Omission Not Waiver.

     No delay or omission of the Trustee, any Holder of any Securities or any holder of any
Preferred Security to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article V or by law to the Trustee or to the
Holders and the right and remedy given to the holders of Preferred Securities by Section
5.8 may be exercised from time to time, and as often as may be deemed expedient, by the
Trustee, the Holders or the holders of Preferred Securities, as the case may be.

     SECTION 5.12. Control by Holders.

     The Holders of not less than a majority in aggregate principal amount of the Outstanding
Securities (or, as the case may be, the holders of a majority in aggregate Liquidation Amount of
the Preferred Securities) shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust or power conferred
on the Trustee; provided, that:

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

     (b) the Trustee may take any other action deemed proper by the Trustee that is not
inconsistent with such direction, and

     (c) subject to the provisions of Section 6.2, the Trustee shall have the right to
decline to follow such direction if a Responsible Officer or Officers of the Trustee shall, in good
faith, reasonably determine that the proceeding so directed would be unjustly prejudicial to the
Holders not joining in any such direction or would involve the Trustee in personal liability.

     SECTION 5.13. Waiver of Past Defaults.

     (a) The Holders of not less than a majority in aggregate principal amount of the
Outstanding Securities and the holders of not less than a majority in aggregate Liquidation
Amount of the Preferred Securities may waive any past Event of Default hereunder and its
consequences except an Event of Default:

     (i) in the payment of the principal of or any premium or interest (including any
Additional Interest) on any Security (unless such Event of Default has been cured and the
Company has paid to or deposited with the Trustee a sum sufficient to pay all installments
of interest (including any Additional Interest) due and past due and all principal of and
any premium on all Securities due otherwise than by acceleration), or

     (ii) in respect of a covenant or provision hereof that under Article IX
cannot be modified or amended without the consent of each Holder of any Outstanding
Security.

33

 

     (b) Any such waiver shall be deemed to be on behalf of the Holders of all the Securities or,
in the case of a waiver by holders of Preferred Securities issued by such Trust, by all holders of
Preferred Securities.

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

     SECTION 5.14. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his or her acceptance
thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee
for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of
an undertaking to pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or defenses made by such
party litigant; but the provisions of this Section 5.14 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than ten percent (10%) in aggregate principal amount of the Outstanding
Securities, or to any suit instituted by any Holder for the enforcement of the payment of the
principal of or any premium on the Security after the Stated Maturity or any interest (including
any Additional Interest) on any Security after it is due and payable.

     SECTION 5.15. Waiver of Usury, Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it will not at any time
insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any
usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not hinder, delay or impede the execution of any power herein granted to the Trustee,
but will suffer and permit the execution of every such power as though no such law had been
enacted.

ARTICLE VI

The Trustee

     SECTION 6.1. Corporate Trustee Required.

     There shall at all times be a Trustee hereunder with respect to the Securities. The Trustee
shall be a corporation organized and doing business under the laws of the United States or of any
state thereof, authorized to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000, subject to supervision or examination by Federal or state authority and
having an office within the United States. If such corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of such supervising or

34

 

examining authority, then, for the purposes of this Section 6.1, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 6.1, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article VI.

     SECTION 6.2. Certain Duties and Responsibilities.

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

     (i) the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture, and no implied covenants or obligations shall be
read into this Indenture against the Trustee; and

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

     (b) If an Event of Default known to the Trustee has occurred and is continuing, the Trustee
shall, prior to the receipt of directions, if any, from the Holders of at least a majority in
aggregate principal amount of the Outstanding Securities (or, if applicable, from the holders of a
majority in aggregate Liquidation Amount of the Preferred Securities), exercise such of the rights
and powers vested in it by this Indenture, and use the same degree of care and skill in its
exercise, as a prudent person would exercise or use under the circumstances in the conduct of such
person’s own affairs.

     (c) Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section 6.2.
To the extent that, at law or in equity, the Trustee has duties and liabilities relating to the
Holders, the Trustee shall not be liable to any Holder for the Trustee’s good faith reliance on the
provisions of this Indenture. The provisions of this Indenture, to the extent that they restrict
the duties and liabilities of the Trustee otherwise existing at law or in equity, are agreed by the
Company and the Holders to replace such other duties and liabilities of the Trustee.

     (d) No provisions of this Indenture shall be construed to relieve the Trustee from liability
with respect to matters that are within the authority of the Trustee under this Indenture for its
own negligent action, negligent failure to act or willful misconduct, except that:

35

 

     (i) the Trustee shall not be liable for any error or judgment made in good faith
by an authorized officer of the Trustee, unless it shall be proved that the Trustee was
negligent in ascertaining the pertinent facts;

     (ii) the Trustee shall not be liable with respect to any action taken or omitted
to be taken by it in good faith in accordance with the direction of the Holders of at least
a majority in aggregate principal amount of the Outstanding Securities (or, if applicable,
from the holders of a majority in aggregate Liquidation Amount of the Preferred Securities),
relating to the time, method and place of conducting any proceeding for any remedy available
to the Trustee under this Indenture; and

     (iii) the Trustee shall be under no liability for interest on any money received by
it hereunder and money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law.

     SECTION 6.3. Notice of Defaults.

     Within ninety (90) days after the occurrence of any default actually known to the Trustee, the
Trustee shall give the Holders notice of such default unless such default shall have been cured or
waived; provided, that except in the case of a default in the payment of the principal of or any
premium or interest on any Securities, the Trustee shall be fully protected in withholding the
notice if and so long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determines that withholding the
notice is in the interest of the Holders; and provided, further, that in the case of any default of
the character specified in Section 5.1(d), no such notice to Holders shall be given until
at least thirty (30) days after the occurrence thereof. For the purpose of this Section
6.3, the term “default” means any event which is, or after notice or lapse of time or both
would become, an Event of Default.

     SECTION 6.4. Certain Rights of Trustee.

     Subject to the provisions of Section 6.2:

     (a) the Trustee may conclusively rely and shall be fully protected in acting or refraining
from acting in good faith and in accordance with the terms hereof upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note or other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

     (b) if (i) in performing its duties under this Indenture the Trustee is required to decide
between alternative courses of action, (ii) in construing any of the provisions of this Indenture
the Trustee finds ambiguous or inconsistent with any other provisions contained herein or (iii) the
Trustee is unsure of the application of any provision of this Indenture, then, except as to any
matter as to which the Holders are entitled to decide under the terms of this Indenture, the
Trustee shall deliver a notice to the Company requesting the Company’s written instruction as to
the course of action to be taken and the Trustee shall take such action, or refrain from taking
such action, as the Trustee shall be instructed in writing to take, or to refrain from taking, by
the Company; provided, that if the Trustee does not receive such instructions from the Company

36

 

within ten Business Days after it has delivered such notice or such reasonably shorter period of
time set forth in such notice the Trustee may, but shall be under no duty to, take such action, or
refrain from taking such action, as the Trustee shall deem advisable and in the best interests of
the Holders, in which event the Trustee shall have no liability except for its own negligence, bad
faith or willful misconduct;

     (c) any request or direction of the Company shall be sufficiently evidenced by a Company
Request or Company Order and any resolution of the Board of Directors may be sufficiently
evidenced by a Board Resolution;

     (d) the Trustee may consult with counsel (which counsel may be counsel to the Trustee, the
Company or any of its Affiliates, and may include any of its employees) and the advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon;

     (e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request or direction of any of the Holders or any holder of Preferred
Securities pursuant to this Indenture, unless such Holders (or such holders of Preferred
Securities) shall have offered to the Trustee security or indemnity reasonably satisfactory to it
against the costs, expenses (including reasonable attorneys’ fees and expenses) and liabilities
that might be incurred by it in compliance with such request or direction, including reasonable
advances as may be requested by the Trustee;

     (f) the Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, indenture, note or other paper or document, but the Trustee in its discretion
may make such inquiry or investigation into such facts or matters as it may see fit, and, if the
Trustee shall determine to make such inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;

     (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents, attorneys, custodians or nominees and the
Trustee shall not be responsible for any misconduct or negligence on the part of any such agent,
attorney, custodian or nominee appointed with due care by it hereunder;

     (h) whenever in the administration of this Indenture the Trustee shall deem it desirable
to receive instructions with respect to enforcing any remedy or right or taking any other action
with respect to enforcing any remedy or right hereunder, the Trustees (i) may request instructions
from the Holders (which instructions may only be given by the Holders of the same aggregate
principal amount of Outstanding Securities as would be entitled to direct the Trustee under this
Indenture in respect of such remedy, right or action), (ii) may refrain from enforcing such remedy
or right or taking such action until such instructions are received and (iii) shall be protected in
acting in accordance with such instructions;

37

 

     (i) except as otherwise expressly provided by this Indenture, the Trustee shall not be
under any obligation to take any action that is discretionary under the provisions of this
Indenture;

     (j) without prejudice to any other rights available to the Trustee under applicable law,
when the Trustee incurs expenses or renders services in connection with any bankruptcy, insolvency
or other proceeding referred to in clauses (e) or (f) of the definition of Event of Default, such
expenses (including legal fees and expenses of its agents and counsel) and the compensation for
such services are intended to constitute expenses of administration under any bankruptcy laws or
law relating to creditors rights generally;

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

     (l) the Trustee shall not be charged with knowledge of any default or Event of Default
unless either (i) a Responsible Officer of the Trustee shall have actual knowledge or (ii) the
Trustee shall have received written notice thereof from the Company or a Holder; and

     (m) in the event that the Trustee is also acting as Paying Agent, Authenticating Agent or
Securities Registrar hereunder, the rights and protections afforded to the Trustee pursuant to this
Article VI shall also be afforded such Paying Agent, Authenticating Agent, or Securities
Registrar.

     SECTION 6.5. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Securities Registrar or any other
agent of the Company, in its individual or any other capacity, may become the owner or pledgee of
Securities and may otherwise deal with the Company with the same rights it would have if it were
not Trustee, Authenticating Agent, Paying Agent, Securities Registrar or such other agent.

     SECTION 6.6. Compensation; Reimbursement; Indemnity.

     (a) The Company agrees

     (i) to pay to the Trustee from time to time reasonable compensation for all
services rendered by it hereunder in such amounts as the Company and the Trustee shall agree
from time to time and in accordance with the terms of the Fee Agreement, dated as of August
30, 2007, by and between the Trustee and the Company (which compensation shall not be
limited by any provision of law in regard to the compensation of a trustee of an express
trust);

     (ii) to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with any provision
of this Indenture (including the reasonable compensation and the expenses and

38

 

disbursements of its agents and counsel), except any such expense, disbursement or advance
as may be attributable to its negligence, bad faith or willful misconduct and in accordance
with the terms of the Fee Agreement, dated as of August 30, 2007, by and between the Trustee
and the Company; and

     (iii) to the fullest extent permitted by applicable law, to indemnify the Trustee
(including in its individual capacity) and its Affiliates, and their officers, directors,
shareholders, agents, representatives and employees for, and to hold them harmless against,
any loss, damage, liability, tax (other than income, franchise or other taxes imposed on
amounts paid pursuant to (i) or (ii) hereof), penalty, expense or claim of any kind or
nature whatsoever incurred without negligence, bad faith or willful misconduct on its part
arising out of or in connection with the acceptance or administration of this trust or the
performance of the Trustee’s duties hereunder, including the advancement of funds to cover

instrument accepting such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring
Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer
and deliver to such successor Trustee all property and money held by such retiring Trustee
hereunder.

     (b) Upon request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such successor Trustee all
rights, powers and trusts referred to in paragraph (a) of this Section 6.8.

trust business of the Trustee, shall be the successor of the Trustee hereunder, without the
execution or filing of any paper or any further act on the part of any of the parties hereto,
provided, that such Person shall be otherwise qualified and eligible under this Article VI.
In case any Securities shall have been authenticated, but not delivered, by the Trustee then in
office, any successor by merger, conversion or consolidation or as otherwise provided above in this
Section 6.9 to such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated, and in case any Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of any predecessor
Trustee or in the name of such successor Trustee, and in all cases the certificate of
authentication shall have the full force which it is provided anywhere in the Securities or in this
Indenture that the certificate of the Trustee shall have.

     SECTION 6.10. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee’s certificates of
authentication, shall be taken as the statements of the Company, and neither the Trustee nor any
Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or application by the
Company of the Securities or the proceeds thereof.

     SECTION 6.11. Appointment of Authenticating Agent.

to authenticate Securities issued upon original issue and upon exchange, registration of transfer
or partial redemption thereof or pursuant to Section 3.6, and Securities so authenticated
shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture

authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the

United States of America, or of any State or Territory thereof or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of
not less than $50,000,000 and subject to supervision or examination by Federal or state authority.
If such Authenticating Agent publishes reports of condition at least annually pursuant to law or to
the requirements of said supervising or examining authority, then for the purposes of this
Section 6.11 the combined capital and surplus of such Authenticating Agent shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in

41

resign immediately in the manner and with the effect specified in this Section 6.11.

     (b) Any Person into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any Person resulting from any merger, conversion or consolidation to which
such Authenticating Agent shall be a party, or any Person succeeding to all or substantially all of
the corporate trust business of an Authenticating Agent shall be the successor Authenticating Agent
hereunder, provided such Person shall be otherwise eligible under this Section 6.11,
without the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent.

     (c) An Authenticating Agent may resign at any time by giving written notice thereof to the
Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating
Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon
receiving such a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the provisions of this
Section 6.11, the Trustee may appoint a successor Authenticating Agent eligible under the
provisions of this Section 6.11, which shall be acceptable to the Company, and shall give
notice of such appointment to all Holders. Any successor Authenticating Agent upon acceptance of
its appointment hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an Authenticating Agent.

     (d) The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section 6.11 in such amounts as the Company
and the Authenticating Agent shall agree from time to time.

     (e) If an appointment of an Authenticating Agent is made pursuant to this Section
6.11, the Securities may have endorsed thereon, in addition to the Trustee’s certificate of
authentication, an alternative certificate of authentication in the following form:

This represents Securities designated therein and referred to in the within mentioned Indenture.

the performance or observance of any of the terms, provisions and conditions of this Indenture
(without regard to any period of grace or requirement of notice provided hereunder), and if the
Company shall be in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

     SECTION 10.4. Calculation Agent.

     (a) The Company hereby agrees that for so long as any of the Securities remain Outstanding,
there will at all times be an agent appointed to calculate LIBOR in respect of each Interest
Payment Date in accordance with the terms of Schedule A (the “Calculation Agent”). The
Company has initially appointed the Property Trustee as Calculation Agent for purposes of
determining LIBOR for each Interest Payment Date. The Calculation Agent may be removed by the
Company at any time. Except as described in the immediately preceding sentence, so long as the
Property Trustee holds any of the Securities, the Calculation Agent shall be the Property Trustee.
If the Calculation Agent is unable or unwilling to act as such or is removed by the Company, the
Company will promptly appoint as a replacement Calculation Agent the London office of a leading
bank which is engaged in transactions in Eurodollar deposits in the international Eurodollar market
and which does not control or is not controlled by or under common control with the Company or its
Affiliates. The Calculation Agent may not resign its duties without a successor having been duly
appointed.

     (b) The Calculation Agent shall be required to agree that, as soon as possible after 11:00
a.m. (London time) on each LIBOR Determination Date (as defined in Schedule A), but in no
event later than 11:00 a.m. (London time) on the Business Day immediately following each LIBOR
Determination Date, the Calculation Agent will calculate the interest rate and dollar amount
(rounded to the nearest cent, with half a cent being rounded upwards) for the related Interest
Payment Date, and will communicate such rate and amount to the Company, the Trustee, each Paying
Agent and the Depositary. The Calculation Agent will also specify to the Company the quotations
upon which the foregoing rates and amounts are based and, in any event, the Calculation Agent shall
notify the Company before 5:00 p.m. (London time) on each LIBOR Determination Date that either: (i)
it has determined or is in the process of determining the foregoing rates and amounts or (ii) it
has not determined and is not in the process of determining the foregoing rates and amounts,
together with its reasons therefor. The Calculation Agent’s determination of the foregoing rates
and amounts for any Interest Payment Date will (in the absence of manifest error) be final and
binding upon all parties. For the sole purpose of

49

 

calculating the interest rate for the Securities, “Business Day” shall be defined as any day on
which dealings in deposits in Dollars are transacted in the London interbank market.

     SECTION 10.5. Additional Tax Sums.

     If (a) the Trust is the Holder of all of the Outstanding Securities and (b) a Tax Event
described in clause (i) or (iii) in the definition of Tax Event in Section 1.1 hereof has
occurred and is continuing, the Company shall pay to the Trust (and its permitted successors or
assigns under the related Trust Agreement) for so long as the Trust (or its permitted successor or
assignee) is the registered holder of the Outstanding Securities, such amounts as may be necessary
in order that the amount of Distributions (including any Additional Interest Amount (as defined in
the Trust Agreement)) then due and payable by the Trust on the Preferred Securities and Common
Securities that at any time remain outstanding in accordance with the terms thereof shall not be
reduced as a result of any Additional Taxes arising from such Tax Event (additional such amounts
payable by the Company to the Trust, the “Additional Tax Sums”). Whenever in this Indenture or the
Securities there is a reference in any context to the payment of principal of or interest on the
Securities, such mention shall be deemed to include mention of the payments of the Additional Tax
Sums provided for in this Section 10.5 to the extent that, in such context, Additional Tax
Sums are, were or would be payable in respect thereof pursuant to the provisions of this
Section 10.5 and express mention of the payment of Additional Tax Sums (if applicable) in
any provisions hereof shall not be construed as excluding Additional Tax Sums in those provisions
hereof where such express mention is not made; provided, that the deferral of the payment of
interest pursuant to Section 3.9 on the Securities shall not defer the payment of any
Additional Tax Sums that may be due and payable.

     SECTION 10.6. Additional Covenants.

     (a) The Company covenants and agrees with each Holder of Securities that if an Event of
Default shall have occurred and be continuing or the Company shall have given notice of its
election to begin an Extension Period with respect to the Securities and shall not have rescinded
such notice, or such Extension Period, or any extension thereof, shall be continuing, it shall not
(i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Company’s Equity Interests, (ii) vote in favor of
or permit or otherwise allow any of its Subsidiaries to declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to or
otherwise retire, any of such Subsidiary’s Equity Interests entitling the holders thereof to a
stated rate of return, other than dividends or distributions on Equity Interests issued by any
Subsidiary solely payable to the Company or any Subsidiary thereof (for the avoidance of doubt,
whether such Equity Interests are perpetual or otherwise), or (iii) make any payment of principal
of or any interest or premium on or repay, repurchase or redeem any debt securities of the Company
that rank pari passu in all respects with or junior in interest to the Securities (other than (A)
repurchases, redemptions or other acquisitions of Equity Interests of the Company in connection
with any employment contract, benefit plan or other similar arrangement with or for the benefit of
any one or more employees, officers, directors or consultants, in connection with a dividend
reinvestment or stockholder stock purchase or similar plan with respect to any Equity Interests or
in connection with the issuance of Equity Interests of the Company (or securities convertible into
or exercisable for such Equity Interests) as consideration in an acquisition transaction entered

50

 

into prior to the applicable Event of Default or Extension Period, (B) as a result of an exchange
or conversion of any class or series of the Company’s Equity Interests (or any Equity Interests of
a Subsidiary of the Company) for any class or series of the Company’s Equity Interests or of any
class or series of the Company’s indebtedness for any class or series of the Company’s Equity
Interests, (C) the purchase of fractional interests in Equity Interests of the Company pursuant to
the conversion or exchange provisions of such Equity Interests or the security being converted or
exchanged, (D) any declaration of a dividend in connection with any Rights Plan, the issuance of
rights, Equity Interests or other property under any Rights Plan or the redemption or repurchase of
rights pursuant thereto, or (E) any dividend in the form of Equity Interests, warrants, options or
other rights where the dividend Equity Interests or the Equity Interests issuable upon exercise of
such warrants, options or other rights are the same Equity Interests as those on which the dividend
is being paid or rank pari passu with or junior to such Equity Interests).

     (b) The Company also covenants with each Holder of Securities (i) to hold, directly or
indirectly, one hundred percent (100%) of the Common Securities of the Trust, provided, that any
permitted successor of the Company hereunder may succeed to the Company’s ownership of such Common
Securities, (ii) as holder of such Common Securities, not to voluntarily dissolve, wind-up or
liquidate the Trust other than (A) in connection with a distribution of the Securities to the
holders of the Preferred Securities in liquidation of the Trust or (B) in connection with certain
mergers, consolidations or amalgamations permitted by the Trust Agreement and (iii) to use its
reasonable commercial efforts, consistent with the terms and provisions of the Trust Agreement, to
cause the Trust to continue to be taxable as a grantor trust and not as a corporation for United
States Federal income tax purposes.

     SECTION 10.7. Waiver of Covenants.

     The Company may omit in any particular instance to comply with any covenant or condition
contained in Section 10.6 if, before or after the time for such compliance, the Holders of
at least a majority in aggregate principal amount of the Outstanding Securities shall, by Act of
such Holders, and at least a majority of the aggregate Liquidation Amount of the Preferred
Securities then outstanding, by consent of such holders, either waive such compliance in such
instance or generally waive compliance with such covenant or condition, but no such waiver shall
extend to or affect such covenant or condition except to the extent so expressly waived, and, until
such waiver shall become effective, the obligations of the Company in respect of any such covenant
or condition shall remain in full force and effect.

     SECTION 10.8. Treatment of Securities.

     The Company will treat the Securities as indebtedness, and the amounts (other than payments of
principal) payable in respect of the principal amount of such Securities as interest, for all U.S.
federal income tax purposes. All payments in respect of the Securities will be made free and clear
of U.S. withholding tax to any beneficial owner thereof that has provided an Internal Revenue
Service Form W-9 or W8BEN (or any substitute or successor form) establishing its U.S. or non-U.S.
status for U.S. federal income tax purposes.

the Trustee and the Property Trustee under the Trust Agreement in writing of such date and of the
principal amount of the Securities to be redeemed and provide the additional information required
to be included in the notice or notices contemplated by Section 11.5. In the case of any
redemption of Securities, in whole or in part, (a) prior to the expiration of any restriction on
such redemption provided in this Indenture or the Securities or (b) pursuant to an election of the
Company which is subject to a condition specified in this Indenture or the Securities, the Company
shall furnish the Trustee with an Officers’ Certificate and an Opinion of Counsel evidencing
compliance with such restriction or condition.

     SECTION 11.4. Selection of Securities to be Redeemed.

     (a) If less than all the Securities are to be redeemed, the particular Securities to be
redeemed shall be selected and redeemed on a pro rata basis not more than sixty (60) days prior to
the Redemption Date by the Trustee from the Outstanding Securities not previously called for
redemption by such methods as the Trustee shall deem fair and appropriate, provided, that the
unredeemed portion of the principal amount of any Security shall be in an authorized denomination
(which shall not be less than the minimum authorized denomination) for such Security.

     (b) The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption, the principal amount
thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the case of any Security
redeemed or to be redeemed only in part, to the portion of the principal amount of such Security
that has been or is to be redeemed.

     (c) The provisions of paragraphs (a) and (b) of this Section 11.4 shall not apply with
respect to any redemption affecting only a single Security, whether such Security is to be redeemed
in whole or in part. In the case of any such redemption in part, the unredeemed portion of the
principal amount of the Security shall be in an authorized denomination (which shall not be less
than the minimum authorized denomination) for such Security.

     SECTION 11.5. Notice of Redemption.

     (a) Notice of redemption shall be given in the manner provided in Section 1.6 not later than
the thirtieth (30th) day, and not earlier than the sixtieth (60th) day, prior to the Redemption
Date to each Holder of Securities to be redeemed, in whole or in part (unless a shorter notice
shall be satisfactory to the Property Trustee under the related Trust Agreement).

     (b) With respect to Securities to be redeemed, in whole or in part, each notice of
redemption shall state:

     (i) the Redemption Date;

     (ii) the Redemption Price or, if the Redemption Price cannot be calculated prior
to the time the notice is required to be sent, the estimate of the Redemption Price, as
calculated by the Company, together with a statement that it is an estimate and that the
actual Redemption Price will be calculated on the fifth Business Day prior to the

53

 

Redemption Date (and if an estimate is provided, a further notice shall be sent of the
actual Redemption Price on the date that such Redemption Price is calculated);

     (iii) if less than all Outstanding Securities are to be redeemed, the
identification (and, in the case of partial redemption, the respective principal amounts) of
the particular Securities to be redeemed;

     (iv) that on the Redemption Date, the Redemption Price will become due and payable
upon each such Security or portion thereof, and that any interest (including any Additional
Interest) on such Security or such portion, as the case may be, shall cease to accrue on and
after said date; and

     (v) the place or places where such Securities are to be surrendered for
payment of the Redemption Price.

     (c) Notice of redemption of Securities to be redeemed, in whole or in part, at the
election of the Company shall be given by the Company or, at the Company’s request, by the Trustee
in the name and at the expense of the Company and shall be irrevocable. The notice if mailed in the
manner provided above shall be conclusively presumed to have been duly given, whether or not the
Holder receives such notice. In any case, a failure to give such notice by mail or any defect in
the notice to the Holder of any Security designated for redemption as a whole or in part shall not
affect the validity of the proceedings for the redemption of any other Security.

     SECTION 11.6. Deposit of Redemption Price.

     Prior to 10:00 a.m., New York City time, on the Redemption Date specified in the notice of
redemption given as provided in Section 11.5, the Company will deposit with the Trustee or
with one or more Paying Agents (or if the Company is acting as its own Paying Agent, the Company
will segregate and hold in trust as provided in Section 10.2) an amount of money sufficient
to pay on the Redemption Date the Redemption Price of, and any accrued interest (including any
Additional Interest) on, all the Securities (or portions thereof) that are to be redeemed on that
date.

     SECTION 11.7. Payment of Securities Called for Redemption.

     (a) If any notice of redemption has been given as provided in Section 11.5, the
Securities or portion of Securities with respect to which such notice has been given shall become
due and payable on the date and at the place or places stated in such notice at the applicable
Redemption Price, together with accrued interest (including any Additional Interest) to the
Redemption Date. On presentation and surrender of such Securities at a Place of Payment specified
in such notice, the Securities or the specified portions thereof shall be paid and redeemed by the
Company at the applicable Redemption Price, together with accrued interest (including any
Additional Interest) to the Redemption Date.

     (b) Upon presentation of any Security redeemed in part only, the Company shall execute and
upon receipt thereof the Trustee shall authenticate and deliver to the Holder thereof, at the
expense of the Company, a new Security or Securities, of authorized denominations, in

54

 

aggregate principal amount equal to the unredeemed portion of the Security so presented and having
the same Original Issue Date, Stated Maturity and terms.

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

ARTICLE XII

Subordination of Securities

     SECTION 12.1. Securities Subordinate to Senior Debt.

     The Company covenants and agrees, and each Holder of a Security, by its acceptance thereof,
likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this
Article XII, the payment of the principal of and any premium and interest (including any
Additional Interest) on each and all of the Securities are hereby expressly made subordinate and
subject in right of payment to the prior payment in full of all Senior Debt.

     SECTION 12.2. No Payment When Senior Debt in Default; Payment Over of Proceeds Upon
Dissolution, Etc.

     (a) In the event and during the continuation of any default by the Company in the payment of
any principal of or any premium or interest on any Senior Debt (following any grace period, if
applicable) when the same becomes due and payable, whether at maturity or at a date fixed for
prepayment or by declaration of acceleration or otherwise, then, upon written notice of such
default to the Company by the holders of such Senior Debt or any trustee therefor, unless and until
such default shall have been cured or waived or shall have ceased to exist, no direct or indirect
payment (in cash, property, securities, by set-off or otherwise) shall be made or agreed to be made
on account of the principal of or any premium or interest (including any Additional Interest) on
any of the Securities, or in respect of any redemption, repayment, retirement, purchase or other
acquisition of any of the Securities.

     (b) In the event of a bankruptcy, insolvency or other proceeding described in clause (e) or
(f) of the definition of Event of Default (each such event, if any, herein sometimes referred to as
a “Proceeding”), all Senior Debt (including any interest thereon accruing after the commencement of
any such proceedings) shall first be paid in full before any payment or distribution, whether in
cash, securities or other property, shall be made to any Holder of any of the Securities on account
thereof. Any payment or distribution, whether in cash, securities or other property (other than
securities of the Company or any other entity provided for by a plan of reorganization or
readjustment the payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the Securities, to the
payment of all Senior Debt at the time outstanding and to any securities issued in respect thereof
under any such plan of reorganization or readjustment), which would otherwise (but for these
subordination provisions) be payable or deliverable in respect of the Securities shall be paid or
delivered directly to the holders of Senior Debt in accordance with the priorities

55

 

then existing among such holders until all Senior Debt (including any interest thereon accruing
after the commencement of any Proceeding) shall have been paid in full.

     (c) In the event of any Proceeding, after payment in full of all sums owing with respect to
Senior Debt, the Holders of the Securities, together with the holders of any obligations of the
Company ranking on a parity with the Securities, shall be entitled to be paid from the remaining
assets of the Company the amounts at the time due and owing on account of unpaid principal of and
premium, if any, and interest (including any Additional Interest) on the Securities and such other
obligations before any payment or other distribution, whether in cash, property or otherwise, shall
be made on account of any Equity Interests or any obligations of the Company ranking junior to the
Securities and such other obligations. If, notwithstanding the foregoing, any payment or
distribution of any character or any security, whether in cash, securities or other property (other
than securities of the Company or any other entity provided for by a plan of reorganization or
readjustment the payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the Securities, to the
payment of all Senior Debt at the time outstanding and to any securities issued in respect thereof
under any such plan of reorganization or readjustment) shall be received by the Trustee or any
Holder in contravention of any of the terms hereof and before all Senior Debt shall have been paid
in full, such payment or distribution or security shall be received in trust for the benefit of,
and shall be paid over or delivered and transferred to, the holders of the Senior Debt at the time
outstanding in accordance with the priorities then existing among such holders for application to
the payment of all Senior Debt remaining unpaid, to the extent necessary to pay all such Senior
Debt (including any interest thereon accruing after the commencement of any Proceeding) in full. In
the event of the failure of the Trustee or any Holder to endorse or assign any such payment,
distribution or security, each holder of Senior Debt is hereby irrevocably authorized to endorse or
assign the same.

     (d) The Trustee and the Holders, at the expense of the Company, shall take such reasonable
action (including the delivery of this Indenture to an agent for any holders of Senior Debt or
consent to the filing of a financing statement with respect hereto) as may, in the opinion of
counsel designated by the holders of a majority in principal amount of the Senior Debt at the time
outstanding, be necessary or appropriate to assure the effectiveness of the subordination effected
by these provisions.

     (e) The provisions of this Section 12.2 shall not impair any rights, interests,
remedies or powers of any secured creditor of the Company in respect of any security interest the
creation of which is not prohibited by the provisions of this Indenture.

     (f) The securing of any obligations of the Company, otherwise ranking on a parity with the
Securities or ranking junior to the Securities, shall not be deemed to prevent such obligations
from constituting, respectively, obligations ranking on a parity with the Securities or ranking
junior to the Securities.

     SECTION 12.3. Payment Permitted If No Default.

     Nothing contained in this Article XII or elsewhere in this Indenture or in any
of the Securities shall prevent (a) the Company, at any time, except during the pendency of
the

56

 

conditions described in paragraph (a) of Section 12.2 or of any Proceeding referred to in
Section 12.2, from making payments at any time of principal of and any premium or interest
(including any Additional Interest) on the Securities or (b) the application by the Trustee of any
moneys deposited with it hereunder to the payment of or on account of the principal of and any
premium or interest (including any Additional Interest) on the Securities or the retention of such
payment by the Holders, if, at the time of such application by the Trustee, it did not have
knowledge (in accordance with Section 12.8) that such payment would have been prohibited by
the provisions of this Article XII, except as provided in Section 12.8.

     SECTION 12.4. Subrogation to Rights of Holders of Senior Debt.

     Subject to the payment in full of all amounts due or to become due on all Senior Debt, or the
provision for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of Senior Debt, the Holders of the Securities shall be subrogated to the extent of the
payments or distributions made to the holders of such Senior Debt pursuant to the provisions of
this Article XII (equally and ratably with the holders of all indebtedness of the Company
that by its express terms is subordinated to Senior Debt of the Company to substantially the same
extent as the Securities are subordinated to the Senior Debt and is entitled to like rights of
subrogation by reason of any payments or distributions made to holders of such Senior Debt) to the
rights of the holders of such Senior Debt to receive payments and distributions of cash, property
and securities applicable to the Senior Debt until the principal of and any premium and interest
(including any Additional Interest) on the Securities shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior Debt of any cash, property
or securities to which the Holders of the Securities or the Trustee would be entitled except for
the provisions of this Article XII, and no payments made pursuant to the provisions of this
Article XII to the holders of Senior Debt by Holders of the Securities or the Trustee,
shall, as among the Company, its creditors other than holders of Senior Debt, and the Holders of
the Securities, be deemed to be a payment or distribution by the Company to or on account of the
Senior Debt.

     SECTION 12.5. Provisions Solely to Define Relative Rights.

     The provisions of this Article XII are and are intended solely for the purpose of
defining the relative rights of the Holders of the Securities on the one hand and the holders of
Senior Debt on the other hand. Nothing contained in this Article XII or elsewhere in this
Indenture or in the Securities is intended to or shall (a) impair, as between the Company and the
Holders of the Securities, the obligations of the Company, which are absolute and unconditional, to
pay to the Holders of the Securities the principal of and any premium and interest (including any
Additional Interest) on the Securities as and when the same shall become due and payable in
accordance with their terms, (b) affect the relative rights against the Company of the Holders of
the Securities and creditors of the Company other than their rights in relation to the holders of
Senior Debt or (c) prevent the Trustee or the Holder of any Security (or to the extent expressly
provided herein, the holder of any Preferred Security) from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, including filing and voting claims
in any Proceeding, subject to the rights, if any, under this Article XII of the holders of
Senior Debt to receive cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder.

57

 

     SECTION 12.6. Trustee to Effectuate Subordination.

     Each Holder of a Security by his or her acceptance thereof authorizes and directs the Trustee
on his or her behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination provided in this Article XII and appoints the Trustee his or
her attorney-in-fact for any and all such purposes.

     SECTION 12.7. No Waiver of Subordination Provisions.

     (a) No right of any present or future holder of any Senior Debt to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act
on the part of the Company or by any act or failure to act, in good faith, by any such holder, or
by any noncompliance by the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof that any such holder may have or be otherwise charged with.

     (b) Without in any way limiting the generality of paragraph (a) of this Section 12.7,
the holders of Senior Debt may, at any time and from to time, without the consent of or notice to
the Trustee or the Holders of the Securities, without incurring responsibility to such Holders of
the Securities and without impairing or releasing the subordination provided in this Article
XII or the obligations hereunder of such Holders of the Securities to the holders of Senior
Debt, do any one or more of the following: (i) change the manner, place or terms of payment or
extend the time of payment of, or renew or alter, Senior Debt, or otherwise amend or supplement in
any manner Senior Debt or any instrument evidencing the same or any agreement under which Senior
Debt is outstanding, (ii) sell, exchange, release or otherwise deal with any property pledged,
mortgaged or otherwise securing Senior Debt, (iii) release any Person liable in any manner for the
payment of Senior Debt and (iv) exercise or refrain from exercising any rights against the Company
and any other Person.

     SECTION 12.8. Notice to Trustee.

     (a) The Company shall give prompt written notice to a Responsible Officer of the Trustee
of any fact known to the Company that would prohibit the making of any payment to or by the Trustee
in respect of the Securities. Notwithstanding the provisions of this Article XII or any
other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts that would prohibit the making of any payment to or by the Trustee in respect of the
Securities, unless and until a Responsible Officer of the Trustee shall have received written
notice thereof from the Company or a holder of Senior Debt or from any trustee, agent or
representative therefor; provided, that if the Trustee shall not have received the notice provided
for in this Section 12.8 at least two Business Days prior to the date upon which by the
terms hereof any monies may become payable for any purpose (including, the payment of the principal
of and any premium on or interest (including any Additional Interest) on any Security), then,
anything herein contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such monies and to apply the same to the purpose for which they were received
and shall not be affected by any notice to the contrary that may be received by it within two
Business Days prior to such date.

58

 

     (b) The Trustee shall be entitled to rely on the delivery to it of a written notice by a
Person representing himself or herself to be a holder of Senior Debt (or a trustee, agent,
representative or attorney-in-fact therefor) to establish that such notice has been given by a
holder of Senior Debt (or a trustee, agent, representative or attorney-in-fact therefor). In the
event that the Trustee determines in good faith that further evidence is required with respect to
the right of any Person as a holder of Senior Debt to participate in any payment or distribution
pursuant to this Article XII, the Trustee may request such Person to furnish evidence to
the reasonable satisfaction of the Trustee as to the amount of Senior Debt held by such Person, the
extent to which such Person is entitled to participate in such payment or distribution and any
other facts pertinent to the rights of such Person under this Article XII, and if such
evidence is not furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

     SECTION 12.9. Reliance on Judicial Order or Certificate of Liquidating Agent.

     Upon any payment or distribution of assets of the Company referred to in this Article
XII, the Trustee and the Holders of the Securities shall be entitled to conclusively rely upon
any order or decree entered by any court of competent jurisdiction in which such Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian,
assignee for the benefit of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of the Senior Debt and
other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon and all other facts pertinent thereto or to this Article XII.

     SECTION 12.10. Trustee Not Fiduciary for Holders of Senior Debt.

     The Trustee, in its capacity as trustee under this Indenture, shall not owe or be deemed to
owe any fiduciary duty to the holders of Senior Debt and shall not be liable to any such holders if
it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company
or to any other Person cash, property or securities to which any holders of Senior Debt shall be
entitled by virtue of this Article XII or otherwise.

     SECTION 12.11. Rights of Trustee as Holder of Senior Debt; Preservation of Trustee’s Rights.

     The Trustee in its individual capacity shall be entitled to all the rights set forth in this
Article XII with respect to any Senior Debt that may at any time be held by it, to the same
extent as any other holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee
of any of its rights as such holder. With respect to the holders of Senior Debt of the Company, the
Trustee undertakes to perform only such of its obligations as are specifically set forth in this
Article XII, and no implied covenants or obligations with respect to the holders of such Senior
Debt shall be read into this Indenture against the Trustee. Nothing in this Article XII shall apply
to claims of, or payments to, the Trustee under or pursuant to Section 6.6.

59

 

     SECTION 12.12. Article Applicable to Paying Agents.

     If at any time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term “Trustee” as used in this Article XII shall
in such case (unless the context otherwise requires) be construed as extending to and including
such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article XII in addition to or in place of the Trustee; provided, that
Sections 12.8 and 12.11 shall not apply to the Company or any Affiliate of the
Company if the Company or such Affiliate acts as Paying Agent.

     This instrument may be executed in any number of counterparts, each of which so executed shall
be deemed to be an original, but all such counterparts shall together constitute but one and the
same instrument. Delivery of an executed signature page of this Indenture by facsimile transmission
shall be effective as delivery of a manually executed counterpart hereof.

Schedule A

DETERMINATION OF LIBOR

     With respect to the Securities, the London interbank offered rate (“LIBOR”) shall be
determined by the Calculation Agent in accordance with the following provisions (in each case
rounded to the nearest .000001%):

(1) On the second LIBOR Business Day (as defined below) prior to an Interest Payment Date (each
such day, a “LIBOR Determination Date”), LIBOR for any given security shall, for the following
interest payment period, equal the rate, as obtained by the Calculation Agent from Bloomberg
Financial Markets Commodities News, for three-month U.S. Dollar deposits in Europe, which appears
on Dow Jones Telerate Page 3750 (as defined in the International Swaps and Derivatives Association,
Inc. 1991 Interest Rate and Currency Exchange Definitions), or such other page as may replace such
Page 3750, as of 11:00 a.m. (London time) on such LIBOR Determination Date.

(2) If, on any LIBOR Determination Date, such rate does not appear on Dow Jones Telerate Page 3750
or such other page as may replace such Page 3750, the Calculation Agent shall determine the
arithmetic mean of the offered quotations of the Reference Banks (as defined below) to leading
banks in the London interbank market for three-month U.S. Dollar deposits in Europe in an amount
determined by the Calculation Agent by reference to requests for quotations as of approximately
11:00 a.m. (London time) on the LIBOR Determination Date made by the Calculation Agent to the
Reference Banks. If, on any LIBOR Determination Date, at least two of the Reference Banks provide
such quotations, LIBOR shall equal such arithmetic mean of such quotations. If, on any LIBOR
Determination Date, only one or none of the Reference Banks provide such quotations, LIBOR shall be
deemed to be the arithmetic mean of the offered quotations that leading banks in the City of New
York selected by the Calculation Agent are quoting on the relevant LIBOR Determination Date for
three-month U.S. Dollar deposits in Europe in an amount determined by the Calculation Agent by
reference to the principal London offices of leading banks in the London interbank market; provided
that, if the Calculation Agent is required but is unable to determine a rate in accordance with at
least one of the procedures provided above, LIBOR shall be LIBOR as determined on the previous
LIBOR Determination Date.

(3) As used herein: “Reference Banks” means four major banks in the London interbank market
selected by the Calculation Agent; and “LIBOR Business Day” means a day on which commercial banks
are open for business (including dealings in foreign exchange and foreign currency deposits) in
London.

     Mercantile Bancorp, Inc., a corporation organized and existing under the laws of Delaware
(hereinafter called the “Company,” which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to                     
(the “Holder”), or registered assigns, the principal sum of $                    
DOLLARS [if the Security is a Global Security, then insert— or such other principal amount
represented hereby as may be set forth in the records of the Securities Registrar hereinafter
referred to in accordance with the Indenture] on October 30, 2037. The Company further promises to
pay interest on said principal sum from August 30, 2007, or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, quarterly (subject to deferral as set
forth herein) in arrears on January 30, April 30, July 30 and October 30 of each year, commencing
on October 30, 2007 or if any such day is not a Business Day, on the next succeeding Business Day
(and no interest shall accrue in respect of the amounts whose payment is so delayed for the period
from and after such Interest Payment Date until such next succeeding Business Day), except that, if
such Business Day falls in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case, with the same force and effect as if made on the
Interest Payment Date, at a a fixed rate per annum equal to 6.84% through the interest payment date
in October, 2017, and a variable rate of interest, per annum, reset quarterly, equal to LIBOR plus
1.58% thereafter, together with Additional Tax Sums, if any, as provided in Section 10.5 of
the Indenture, until the principal hereof is paid or duly provided for or made available for
payment; provided, that any overdue principal, premium, if any, or Additional Tax Sums and any
overdue installment of interest shall bear Additional Interest (to the extent that the payment of
such interest shall be legally enforceable) at a fixed rate per annum equal to 6.84% through the
interest payment date in October, 2017, and a variable rate of interest, per annum, reset
quarterly, equal to LIBOR plus 1.58% thereafter, compounded quarterly, from the dates such amounts
are due until they are paid or made available for payment, and such interest shall be payable on
demand.

     The amount of interest payable for any interest period shall be computed and paid on the basis
of a 360-day year and the actual number of days elapsed in the relevant interest period. The
interest so payable, and punctually paid or duly provided for, on any Interest Payment Date shall,
as provided in the Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular Record Date for such
interest installment. Any such interest not so punctually paid or duly provided for shall forthwith
cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person
in whose name this Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities not less than ten (10) days prior
to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange or automated quotation system on which the
Securities may be listed, traded or quoted and upon such notice as may be required by such exchange
or automated quotation system, all as more fully provided in the Indenture.

     So long as no Event of Default pursuant to Sections 5.1(c), (e), (f),
(g) or (h) of the Indenture has occurred and is continuing, the Company shall have
the right, at any time and from time to time during the term of this Security, to defer the payment
of interest on this Security for a period of up to twenty (20) consecutive quarterly interest
payment periods (each such period, an “Extension Period”), during which Extension Period(s), no
interest shall be due and payable (except any Additional Tax Sums that may be due and payable). No
Extension Period shall end on a date other than an Interest Payment Date, and no Extension Period
shall extend beyond the Stated Maturity of the principal of this Security. No interest shall be due
and payable during an Extension Period (except any Additional Tax Sums that may be due and
payable), except at the end thereof, but each installment of interest that would otherwise have
been due and payable during such Extension Period shall bear Additional Interest (to the extent
payment of such interest would be legally enforceable) at a fixed rate per annum equal to 6.84%
through the interest payment date in October, 2017, and a variable rate, per annum, reset
quarterly, equal to LIBOR plus 1.58% thereafter, compounded quarterly, from the dates on which
amounts would have otherwise been due and payable until paid or made available for payment. At the
end of any such Extension Period, the Company shall pay all interest then accrued and unpaid on
this Security, together with such Additional Interest. Prior to the termination of any such
Extension Period, the Company may further defer the payment of interest; provided, that (i) all
such previous and further extensions comprising such Extension Period do not exceed twenty (20)
quarterly interest payment periods, (ii) no Extension Period shall end on a date other than an
Interest Payment Date and (iii) no Extension Period shall extend beyond the Stated Maturity of the
principal of this Security. Upon the termination of any such Extension Period and upon the payment
of all accrued and unpaid interest and any Additional Interest then due on any Interest Payment
Date, the Company may elect to begin a new Extension Period; provided, that (i) such Extension
Period does not exceed twenty (20) quarterly interest payment periods, (ii) no Extension Period
shall end on a date other than an Interest Payment Date, (iii) no Extension Period shall extend
beyond the Stated Maturity of the principal of this Security and (iv) no Event of Default pursuant
to Sections 5.1(c), (e), (f), (g) or (h) has occurred and
is continuing. The Company shall give (i) the Holder of this Security, (ii) the Trustee, (iii) the
Property Trustee and (iv) any beneficial owner of the Preferred Securities reasonably identified to
the Company (which identification may be made either by such beneficial owner or by the the
Purchaser) written notice of its election to begin any such Extension Period no later than the
close of business on the fifteenth (15th) Business Day prior to the next succeeding
Interest Payment Date on which interest on this Security would be payable but for such deferral.

     During any such Extension Period, the Company shall not (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any
of the Company’s Equity Interests, (ii) vote in favor of or permit or otherwise allow any of its
Subsidiaries to declare or pay any dividends or distributions on, or redeem, purchase, acquire or
make a liquidation payment with respect to or otherwise retire, any of such Subsidiary’s Equity
Interests entitling the holders thereof to a stated rate of return, other than dividends or
distributions on Equity Interests issued by any Subsidiary solely payable to the Company or any
Subsidiary thereof (for the avoidance of doubt, whether such Equity Interests are perpetual or
otherwise), or (iii) make any payment of principal of or any interest or premium on or repay,
repurchase or redeem any debt securities of the Company that rank pari passu in all respects with
or junior in interest to this Security (other than (a) repurchases, redemptions or

A-5

 

other acquisitions of Equity Interests of the Company in connection with (1) any employment
contract, benefit plan or other similar arrangement with or for the benefit of any one or more
employees, officers, directors or consultants, (2) a dividend reinvestment or stockholder stock
purchase or similar plan with respect to any Equity Interests or (3) the issuance of Equity
Interests of the Company (or securities convertible into or exercisable for such Equity Interests)
as consideration in an acquisition transaction entered into prior to the applicable Extension
Period, (b) as a result of an exchange or conversion of any class or series of the Company’s Equity
Interests (or any Equity Interests of a Subsidiary of the Company) for any class or series of the
Company’s Equity Interests or of any class or series of the Company’s indebtedness for any class or
series of the Company’s Equity Interests, (c) the purchase of fractional interests in Equity
Interests of the Company pursuant to the conversion or exchange provisions of such Equity Interests
or the security being converted or exchanged, (d) any declaration of a dividend in connection with
any Rights Plan, the issuance of rights, Equity Interests or other property under any Rights Plan,
or the redemption or repurchase of rights pursuant thereto or (e) any dividend in the form of
Equity Interests, warrants, options or other rights where the dividend Equity Interests or the
Equity Interests issuable upon exercise of such warrants, options or other rights are the same
Equity Interests as those on which the dividend is being paid or rank pari passu with or junior to
such Equity Interests).

     Payment of principal of, premium, if any, and interest on this Security shall be made in such
coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts. Payments of principal, premium, if any, and interest due at
the Maturity of this Security shall be made at the office or agency of the Company maintained for
that purpose in the Place of Payment upon surrender of such Securities to the Paying Agent, and
payments of interest shall be made, subject to such surrender where applicable, by wire transfer at
such place and to such account at a banking institution in the United States as may be designated
in writing to the Paying Agent at least ten (10) Business Days prior to the date for payment by the
Person entitled thereto unless proper written wire transfer instructions have not been received by
the relevant record date, in which case such payments shall be made by check mailed to the address
of such Person as such address shall appear in the Security Register. Notwithstanding the
foregoing, so long as the Holder of this Security is the Property Trustee, the payment of the
principal of (and premium, if any) and interest (including any overdue installment of interest and
Additional Tax Sums, if any) on this Security will be made at such place and to such account as may
be designated by the Property Trustee.

     The indebtedness evidenced by this Security is, to the extent provided in the Indenture,
subordinate and junior in right of payment to the prior payment in full of all Senior Debt, and
this Security is issued subject to the provisions of the Indenture with respect thereto. Each
Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his or her behalf to take such actions as may
be necessary or appropriate to effectuate the subordination so provided and (c) appoints the
Trustee his or her attorney-in-fact for any and all such purposes. Each Holder hereof, by his or
her acceptance hereof, waives all notice of the acceptance of the subordination provisions
contained herein and in the Indenture by each holder of Senior Debt, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said provisions.

     Unless the certificate of authentication hereon has been executed by the Trustee by manual
signature of one of its authorized signatories, this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

     IN WITNESS WHEREOF, the Company has duly executed this certificate this ___ day of                     , 2007.

[FORM OF REVERSE OF SECURITY]

     This Security is one of a duly authorized issue of securities of the Company (the
“Securities”) issued under the Junior Subordinated Indenture, dated as of August 30, 2007 (the
“Indenture”), between the Company and Wilmington Trust Company, as Trustee (in such capacity, the
“Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the
holders of Senior Debt and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered.

     All terms used in this Security that are defined in the Indenture or in the Amended and
Restated Trust Agreement, dated as of August 30, 2007 (as modified, amended or supplemented from
time to time, the “Trust Agreement”), relating to Mercantile Bancorp Capital Trust IV (the
“Trust”), among the Company, as Depositor, the trustees named therein and the holders from time to
time of the Trust Securities issued pursuant thereto, shall have the meanings assigned to them in
the Indenture or the Trust Agreement, as the case may be.

     The Company may, on any Interest Payment Date, at its option, upon not less than thirty (30)
days’ nor more than sixty (60) days’ written notice to the Holders of the Securities (unless a
shorter notice period shall be satisfactory to the Trustee) on or after October 30, 2017 and
subject to the terms and conditions of Article XI of the Indenture, redeem this Security in
whole at any time or in part from time to time at a Redemption Price equal to one hundred percent
(100%) of the principal amount hereof, together, in the case of any such redemption, with accrued
interest, including any Additional Interest, to but excluding the date fixed for redemption;
provided, that the Company shall have received the prior approval of the Federal Reserve if then
required.

     In addition, upon the occurrence and during the continuation of a Special Event, the Company
may, at its option, upon not less than thirty (30) days’ nor more than sixty (60) days’ written
notice to the Holders of the Securities (unless a shorter notice period shall be satisfactory to
the Trustee), redeem this Security, in whole but not in part, subject to the terms and conditions
of Article XI of the Indenture at the Special Event Redemption Price; provided, that the
Company shall have received the prior approval of the Federal Reserve if then required.

     In the event of redemption of this Security in part only, a new Security or Securities for the
unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation
hereof. If less than all the Securities are to be redeemed, the particular Securities to be
redeemed shall be selected not more than sixty (60) days prior to the Redemption Date by the
Trustee from the Outstanding Securities not previously called for redemption, by such method as the
Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security.

     The Indenture permits, with certain exceptions as therein provided, the Company and the
Trustee at any time to enter into a supplemental indenture or indentures for the purpose of
modifying in any manner the rights and obligations of the Company and of the Holders of the
Securities, with the consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities. The Indenture also contains provisions permitting Holders of specified

A-8

 

percentages in principal amount of the Securities, on behalf of the Holders of all Securities, to
waive compliance by the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the Holder of this
Security shall be conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

     No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and any premium and interest, including any Additional Interest, on this Security
at the times, place and rate, and in the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Security is registrable in the Securities Register, upon surrender of this
Security for registration of transfer at the office or agency of the Company maintained for such
purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory
to the Company and the Securities Registrar and duly executed by, the Holder hereof or such
Holder’s attorney duly authorized in writing, and thereupon one or more new Securities, of like
tenor, of authorized denominations and for the same aggregate principal amount, will be issued to
the designated transferee or transferees.

     The Securities are issuable only in registered form without coupons in minimum denominations
of $100,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and
subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate
principal amount of Securities and of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.

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

     The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in
whose name this Security is registered as the owner hereof for all purposes, whether or not this
Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by
notice to the contrary.

     The Company and, by its acceptance of this Security or a beneficial interest herein, the
Holder of, and any Person that acquires a beneficial interest in, this Security agree that, for
United States federal, state and local tax purposes, it is intended that this Security constitute
indebtedness.

     This Security shall be construed and enforced in accordance with and governed by the laws
of the State of New York, without reference to its conflict of laws provisions (other than
Section 5-1401 of the General Obligations Law).
