            THIS INDENTURE, dated as of October 21, 2004, between Horizon
Bancorp, a bank holding company incorporated in the State of Indiana
(hereinafter sometimes called the "Company"), and Wilmington Trust Company, a
Delaware banking corporation, as trustee (hereinafter sometimes called the
"Trustee").

                                   WITNESSETH:

            WHEREAS, for its lawful corporate purposes, the Company has duly
authorized the issuance of its Floating Rate Junior Subordinated Debt Securities
due 2034 (the "Debt Securities") under this Indenture and to provide, among
other things, for the execution and authentication, delivery and administration
thereof, the Company has duly authorized the execution of this Indenture.

            NOW, THEREFORE, in consideration of the premises, and the purchase
of the Debt Securities by the holders thereof, the Company covenants and agrees
with the Trustee for the equal and proportionate benefit of the respective
holders from time to time of the Debt Securities as follows:

                                    ARTICLE I
                                   DEFINITIONS

            Section 1.01 Definitions.

            The terms defined in this Section 1.01 (except as herein otherwise
expressly provided or unless the context otherwise requires) for all purposes of
this Indenture and of any indenture supplemental hereto shall have the
respective meanings specified in this Section 1.01. All accounting terms used
herein and not expressly defined shall have the meanings assigned to such terms
in accordance with generally accepted accounting principles and the term
"generally accepted accounting principles" means such accounting principles as
are generally accepted in the United States at the time of any computation. The
words "herein," "hereof" and "hereunder" and other words of similar import refer
to this Indenture as a whole and not to any particular Article, Section or other
subdivision.

            "Additional Amounts" has the meaning set forth in Section 3.06.

            "Additional Provisions" has the meaning set forth in Section 15.01.

            "Administrative Action" has the meaning specified within the
definition of "Tax Event" in this Section 1.01.

            "Authenticating Agent" means any agent or agents of the Trustee
which at the time shall be appointed and acting pursuant to Section 6.12.

            "Bankruptcy Law" means Title 11, U.S. Code, or any similar federal
or state law for the relief of debtors.

            "Board of Directors" means the board of directors or the executive
committee or any other duly authorized designated officers of the Company.

<PAGE>

            "Board Resolution" means a copy of a resolution certified by the
Secretary or an Assistant Secretary of the Company to have been duly adopted by
the Board of Directors and to be in full force and effect on the date of such
certification and delivered to the Trustee.

            "Business Day" means any day other than a Saturday, Sunday or any
other day on which banking institutions in Wilmington, Delaware, The City of New
York or Indianapolis, Indiana are permitted or required by law or executive
order to close.

            "Calculation Agent" means the Person identified as "Trustee" in the
first paragraph hereof with respect to the Debt Securities and the Institutional
Trustee with respect to the Trust Securities.

            "Capital Securities" means undivided beneficial interests in the
assets of the Trust which are designated as "MMCapS(SM)" and rank pari passu
with Common Securities issued by the Trust; provided, however, that if an Event
of Default (as defined in the Declaration) has occurred and is continuing, the
rights of holders of such Common Securities to payment in respect of
distributions and payments upon liquidation, redemption and otherwise are
subordinated to the rights of holders of such Capital Securities.

            "Capital Securities Guarantee" means the guarantee agreement that
the Company will enter into with Wilmington Trust Company or other Persons that
operates directly or indirectly for the benefit of holders of Capital Securities
of the Trust.

            "Capital Treatment Event" means, if the Company is organized and
existing under the laws of the United States or any state thereof or the
District of Columbia, the receipt by the Company and the Trust of an Opinion of
Counsel experienced in such matters to the effect that, as a result of any
amendment to, or change in, the laws, rules or regulations of the United States
or any political subdivision thereof or therein, or as the result of any
official or administrative pronouncement or action or decision interpreting or
applying such laws, rules or regulations, which amendment or change is effective
or which pronouncement, action or decision is announced on or after the date of
original issuance of the Debt Securities, there is more than an insubstantial
risk that the Company will not, within 90 days of the date of such opinion, be
entitled to treat an amount equal to the aggregate Liquidation Amount of the
Capital Securities as "Tier 1 Capital" (or the then equivalent thereof) for
purposes of the capital adequacy guidelines of the Federal Reserve (or any
successor regulatory authority with jurisdiction over bank holding companies),
as then in effect and applicable to the Company; provided, however, that the
inability of the Company to treat all or any portion of the aggregate
Liquidation Amount of the Capital Securities as "Tier 1 Capital" shall not
constitute the basis for a Capital Treatment Event if such inability results
from the Company having cumulative preferred stock, minority interests in
consolidated subsidiaries and any other class of security or interest which the
Federal Reserve (or any successor regulatory authority with jurisdiction over
bank holding companies) may now or hereafter accord "Tier 1 Capital" treatment
that, in the aggregate, exceed the amount which may now or hereafter qualify for
treatment as "Tier 1 Capital" under applicable capital adequacy guidelines of
the Federal Reserve (or any successor regulatory authority with jurisdiction
over bank holding companies); provided, further, however, that the distribution
of the Debt Securities in connection with the liquidation of the Trust by the
Company shall not in and of itself constitute a Capital Treatment Event unless
such liquidation shall have occurred in connection

                                       2
<PAGE>

with a Tax Event or an Investment Company Event. For the avoidance of doubt, the
adoption by the Board of Governors of the Federal Reserve System as a final rule
of any of the proposals set forth in its notice of proposed rulemaking dated May
6, 2004, shall not constitute a Capital Treatment Event.

            "Certificate" means a certificate signed by any one of the principal
executive officer, the principal financial officer or the principal accounting
officer of the Company.

            "Code" means the Internal Revenue Code of 1986, as amended.

            "Common Securities" means undivided beneficial interests in the
assets of the Trust which are designated as "Common Securities" and rank pari
passu with Capital Securities issued by the Trust; provided, however, that if an
Event of Default (as defined in the Declaration) has occurred and is continuing,
the rights of holders of such Common Securities to payment in respect of
distributions and payments upon liquidation, redemption and otherwise are
subordinated to the rights of holders of such Capital Securities.

            "Company" means Horizon Bancorp, a bank holding company incorporated
in the State of Indiana, and, subject to the provisions of Article XI, shall
include its successors and assigns.

            "Debt Security" or "Debt Securities" has the meaning stated in the

time.

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

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.

Debt Securities shall cease to be such officer before the Debt Securities so

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

Agent shall authenticate and make available for delivery in exchange therefor,
the Debt Security or Debt Securities which the Securityholder making the
exchange shall be entitled to receive. Upon due presentment for registration of

Security for a like aggregate principal amount. Registration or registration of

Security.

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

            No service charge shall be made for any exchange or registration of

of a sum sufficient to cover any tax, fee or other governmental charge that may
be imposed in connection therewith other than exchanges pursuant to Section
2.07, Section 9.04 or Section 10.04 not involving any transfer.

            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

            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 (THE "FDIC"). THIS OBLIGATION IS SUBORDINATED TO THE
CLAIMS OF THE 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

                                       13
<PAGE>

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.

            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 (i) in the case of the initial Interest Period, for the period
from, and including, the date of original issuance of such Debt Security to, but
excluding, the initial Interest Payment Date and (ii) thereafter, for the period
from, and including, the first day following the end of the preceding Interest
Period to, but excluding, the applicable Interest Payment Date or, in the case
of the last Interest Period, the related Optional 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

                                       14
<PAGE>

(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 and on the Maturity Date, any Optional Redemption Date or
the Special Redemption Date, as the case may be. Interest and any Deferred
Interest on any Debt Security that is payable, and is punctually paid or duly
provided for by the Company, 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, any Optional Redemption Date or the Special Redemption Date,
as the case may be, shall be paid to the Person to whom principal is paid. In
case (i) the Maturity Date of any Debt Security or (ii) any Debt Security or
portion thereof is called for redemption and the related Optional Redemption
Date or the Special Redemption Date, as the case may be, is subsequent to the
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 by the Company,
on any Interest Payment Date (herein called "Defaulted Interest") shall
forthwith cease to be payable to the holder on the relevant regular record date
by virtue of having been such holder, and such Defaulted Interest 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 reasonably 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 provided
in this paragraph. 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.

                                       15
<PAGE>

            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 day 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 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 any Interest Period will be
computed on the basis of a 360-day year and the actual number of days elapsed in
such Interest Period.

            (b) LIBOR shall be determined by the Calculation Agent for each
Interest Period (other than the first Interest Period, in which case LIBOR will
be 2.10% per annum) in accordance with the following provisions:

                  (i) 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 the Interest Payment Date that commences 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 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 ("Telerate Page 3750"). "LIBOR Business Day" means any day that is
      not a Saturday, Sunday or other day on which commercial banking
      institutions in The City of 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)

                                       16
<PAGE>

      on such LIBOR Determination Date, the corrected rate as so substituted
      will be LIBOR for such LIBOR Determination Date.

                  (ii) If, on such LIBOR Determination Date, such rate does not
      appear on Telerate Page 3750, the Calculation Agent shall determine the
      arithmetic mean of the offered quotations of the Reference Banks 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 such LIBOR Determination Date made by the Calculation
      Agent to the Reference Banks. If, on such LIBOR Determination Date, at
      least two of the Reference Banks provide such quotations, LIBOR shall
      equal the arithmetic mean of such quotations. If, on such 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 such 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.

                  (iii) 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 for such Interest Period shall be LIBOR in effect
      for the immediately preceding Interest Period.

            (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 that applies to the related Interest Period. The Calculation Agent shall,
upon the request of a holder of any Debt Securities, inform such holder of the
Interest Rate that applies to the related Interest Period. 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 applicable 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

                                       17
<PAGE>

term of the Debt Securities, for up to 20 consecutive quarterly periods (each
such extended interest payment period, together with all previous and further
consecutive extensions thereof, is referred to herein as an "Extension Period").
No Extension Period may end on a date other than an Interest Payment Date or
extend beyond the Maturity Date, any Optional Redemption Date or the Special
Redemption Date, as the case may be. 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 an annual rate equal to the Interest Rate applicable
during such Extension Period, compounded quarterly from the date such Deferred
Interest would have been payable were it not for the Extension Period, to the
extent permitted by applicable law. No interest or Deferred Interest (except any
Additional Amounts 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 Extension
Period, the Company shall pay all Deferred Interest then accrued and unpaid on
the Debt Securities; provided, however, that during any Extension Period, the
Company shall be subject to the restrictions set forth in Section 3.08. Prior to
the termination of any Extension Period, the Company may further extend such
Extension Period, provided, that no Extension Period (including all previous and
further consecutive extensions that are part of such Extension Period) shall
exceed 20 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 or extend an Extension Period
at least one Business Day prior to the regular record date applicable to the
next succeeding Interest Payment Date. The Trustee shall give notice of the
Company's election to begin or extend an Extension Period to the
Securityholders, promptly after receipt of notice from the Company of its
election to begin or extend an Extension Period.

            Section 2.12 CUSIP Numbers.

            The Company in issuing the Debt Securities may use a "CUSIP" number
(if then generally in use), and, if so, the Trustee shall use a "CUSIP" number
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 number 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 number.

                                   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 in respect of the Debt
Securities at the place, at the respective times and in the manner provided in
this Indenture and the Debt Securities. Payment of the principal of and premium,
if any, and interest on the Debt Securities due on the Maturity Date, any
Optional Redemption Date or the Special Redemption Date, as the case may be,
will be

                                       18
<PAGE>

made by the Company in immediately available funds against presentation and
surrender of such Debt Securities. At the option of the Company, each
installment of interest on the Debt Securities due on an Interest Payment Date
other than the Maturity Date, any Optional Redemption Date or the Special
Redemption Date, as the case may be, 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 of
immediately available funds to any account with a banking institution located in
the United States designated by such holders to the Paying Agent no later than
the related record date. Notwithstanding anything to the contrary contained in
this Indenture or any Debt Security, if the Trust or the trustee of the Trust is
the holder of any Debt Security, then all payments in respect of such Debt
Security shall be made by the Company in immediately available funds when due.

            (b) The Company will treat the Debt Securities as indebtedness, and
the interest payable in respect of such Debt Securities (including any
Additional Amounts) 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 provided, that (i) any beneficial owner thereof that is a
"United States person" within the meaning of Section 7701(a)(30) of the Code (A)
has provided an Internal Revenue Service Form W-9 (or any substitute or
successor form) in the manner required establishing its status as a "United
States person" for U.S. federal income tax purposes, and (B) the Internal
Revenue Service has neither notified the Issuer that the taxpayer identification
number furnished by such beneficial owner is incorrect nor notified the Issuer
that there is underreporting by such beneficial owner, and (ii) any beneficial
owner thereof that is not a "United States person" within the meaning of Section
7701(a)(30) of the Code has provided an Internal Revenue Service Form W-8 BEN,
Internal Revenue Service Form W-8ECI, or Internal Revenue Service Form W-8EXP,
as applicable (or any substitute or successor form) in the manner required
establishing its non-U.S. status for U.S. federal income tax purposes.

            (c) As of the date of this Indenture, the Company represents that it
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 Indianapolis, Indiana 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

                                       19
<PAGE>

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 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 Indianapolis, Indiana, 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 Indianapolis, Indiana 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
Indianapolis, Indiana 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,

                  (i) 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;

                  (ii) 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

                  (iii) 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 make such payments so

                                       20
<PAGE>

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.

            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 for the Debt Securities (the "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 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 of
the Company 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 Amounts.

            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 Amounts") on the Debt Securities or the Trust Securities, as the
case may be, as shall be required so that the net amounts received and retained
by the holders of Debt Securities or Trust Securities, as the case may be, after
payment of all taxes (including withholding taxes), duties, assessments or other
governmental charges, will be equal to the amounts that such holders would have
received and retained had no such taxes (including withholding taxes), duties,
assessments or other governmental charges 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

                                       21
<PAGE>

mention shall be deemed to include mention of payments of the Additional Amounts
provided for in this Section to the extent that, in such context, Additional
Amounts are, were or would be payable in respect thereof pursuant to the
provisions of this Section and express mention of the payment of Additional
Amounts (if applicable) in any provisions hereof shall not be construed as
excluding Additional Amounts in those provisions hereof where such express
mention is not made, provided, however, that, notwithstanding anything to the
contrary contained in this Indenture or any Debt Security, the deferral of the
payment of interest during an Extension Period pursuant to Section 2.11 shall
not defer the payment of any Additional Amounts that may be due and payable.

            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, convey, transfer or otherwise dispose of all or substantially
all of its property or capital stock 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 premium, if any, or interest 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,

                                       22

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 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 in liquidation of the Trust,
the redemption of all of the Trust Securities or 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

            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

                                       23
<PAGE>

which such applicants propose to transmit, then the Trustee shall within five
Business Days after the receipt of such application, at its election, either:

                  (i) 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

                  (ii) 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 none of the
Company, the Trustee or 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, by hardcopy or electronic
transmission, to (i) each Securityholder each Report on Form 10-K and Form 10-Q,
if any, prepared by the Company and filed with the Securities and Exchange
Commission in accordance with the

                                       24
<PAGE>

Exchange Act within 10 Business Days after the filing thereof or (ii) if the
Company is (a) not then subject to Section 13 or 15(d) of the Exchange Act (a
"Private Entity") or (b) exempt from reporting pursuant to Rule 12g3-2(b)
thereunder, the information required by Rule 144A(d)(4) under the Securities
Act. Notwithstanding the foregoing, so long as a Holder of the Debt Securities
is NBC Capital Markets Group, Inc. or an entity that holds a pool of trust
preferred securities and/or debt securities as collateral for its securities or
a trustee thereof, and the Company is (i) a Private Entity that, on the date of
original issuance of the Debt Securities, is required to provide audited
consolidated financial statements to its primary regulatory authority, (ii) a
Private Entity that, on the date of original issuance of the Debt Securities, is
not required to provide audited consolidated financial statements to its primary
regulatory authority but subsequently becomes subject to the audited
consolidated financial statement reporting requirements of that regulatory
authority or (iii) subject to Section 13 or 15(d) of the Exchange Act on the
date of original issuance of the Debt Securities or becomes so subject after the
date hereof but subsequently becomes a Private Entity, then, within 90 days
after the end of each fiscal year, beginning with the fiscal year in which the
Debt Securities were originally issued if the Company was then subject to (x)
Section 13 or 15(d) of the Exchange Act or (y) audited consolidated financial
statement reporting requirements of its primary regulatory authority or,
otherwise, the earliest fiscal year in which the Company becomes subject to (1)
Section 13 or 15(d) of the Exchange Act or (2) the audited consolidated
financial statement reporting requirements of its primary regulatory authority,
the Company shall deliver, by hardcopy or electronic transmission, to each
Securityholder, unless otherwise provided pursuant to the preceding sentence,
(A) a copy of the Company's audited consolidated financial statements (including
balance sheet and income statement) covering the related annual period and (B)
the report of the independent accountants with respect to such financial
statements. In addition to the foregoing, the Company shall deliver to each
Securityholder 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 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 Debt Securities is NBC
Capital Markets Group, Inc. or an entity that holds a pool of trust preferred
securities and/or debt securities or a trustee thereof, the Company will cause
copies of its reports on Form FR Y-9C to be delivered to such Holder promptly
following their filing with the Federal Reserve.

                                    ARTICLE V
                   REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS

            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

                                       25
<PAGE>

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 Amounts in respect thereof, following
the nonpayment of any such interest for twenty or more consecutive Interest
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, whether at maturity, upon redemption, by
acceleration of maturity pursuant to Section 5.01 of this Indenture 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, appointment or order shall remain unstayed and in effect for a
period of 90 consecutive days; or

            (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) 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

                                       26
<PAGE>

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
non-payment of the payments in respect of Debt Securities which shall have
become due by acceleration, shall have been cured, waived or otherwise remedied
as provided herein, then, in each and 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; provided, however, that if the
Debt Securities are held by the Trust or a trustee of the Trust, such waiver or
rescission and annulment shall not be effective until the holders of a majority
in aggregate liquidation amount of the outstanding Capital Securities of the
Trust shall have consented to such waiver or rescission and annulment.

            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 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

                                       27
<PAGE>

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 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.

                                       28
<PAGE>

            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 upon 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 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, the right of
any holder of any Debt Security to receive payment of the principal of and
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, 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 at the time outstanding and, if the Debt Securities are held
by the Trust or a trustee of the Trust, the holders of a majority in aggregate
liquidation amount of the outstanding Capital Securities of the Trust 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; provided, however, that if
the Debt Securities are held by the Trust or a trustee of the Trust, such time,
method and place or such exercise, as the case may be, may not be so directed
until the holders of a majority in aggregate liquidation amount of the
outstanding Capital Securities of the Trust shall have directed such time,
method and place or such exercise, as the case may be; provided, further, 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

                                       30
<PAGE>

consequences, except a default (a) in the payment of principal of or 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 aggregate
liquidation amount of the outstanding Capital 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 or modification to such waiver shall not be effective until each holder
of the outstanding Capital Securities of the Trust shall have consented to such
waiver or modification to such waiver. Upon any such waiver or modification to
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 or modification to 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, 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 "default" for the purpose of this Section is 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 or 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 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 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 outstanding Debt Securities (or, if such Debt Securities are held
by the Trust or a trustee of the Trust, more than 10% in liquidation amount of
the outstanding Capital Securities),to any suit instituted by

                                       31
<PAGE>

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 or to any suit instituted in
accordance with Section 14.12.

                                   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 or bad faith, except that:

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

                  (i) 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

                  (ii) 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;

            (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

                                       32
<PAGE>

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 that the Trustee
shall be deemed to have knowledge of any 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 Amounts if the Trustee does not
have actual knowledge or written notice that such payment is due and payable) .

            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;

            (e) the Trustee shall not be liable for any action taken or omitted
by it in good faith and reasonably 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 (which 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

                                       33
<PAGE>

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 a majority in aggregate 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, any Authenticating Agent, any Paying Agent, 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 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.

                                       34

            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, willful misconduct or bad faith. 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, willful misconduct 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 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 clause (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.

            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,
willful misconduct or bad faith on the part of the Trustee, be deemed to

                                       35
<PAGE>

be conclusively proved and established by an Officers' Certificate delivered to
the Trustee, and such certificate, in the absence of negligence, willful
misconduct 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 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, 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 ss.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 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

                                       36
<PAGE>

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:

                  (i) 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;

                  (ii) 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

                  (iii) 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 (i),
(ii) or (iii) 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, 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 shall become
effective upon acceptance of appointment by the successor Trustee as provided in
Section 6.10.

            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 indenture supplemental hereto which shall contain such provisions as shall be
deemed necessary or

                                       37
<PAGE>

desirable to confirm that all of the rights, powers, trusts and duties of the
retiring Trustee shall be vested in the successor Trustee, 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.

            No successor Trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor Trustee shall be
eligible and qualified 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, 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.

            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

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, however, 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 corporation
organized and doing business under the laws of the United States or of any state
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 or
District of Columbia authority. If such corporation publishes reports of
condition at least annually pursuant to law or the requirements of such
authority, then for the purposes of this Section 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 successor corporation is
otherwise eligible under this Section 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, the Trustee may, and upon the request of the
Company shall, promptly appoint a successor Authenticating Agent eligible under
this Section, 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 of its
predecessor hereunder, with like effect as if originally named as Authenticating
Agent herein.

                                       39
<PAGE>

            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 or
aggregate liquidation amount of the Capital 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 or holders of Capital Securities,
as the case may be, 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 of such holders of Capital Securities duly called
and held in accordance with the provisions of the Declaration, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of such Securityholders or holders of Capital Securities, as the case
may be, 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 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

                                       40
<PAGE>

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 and premium, if any, and
interest on such Debt Security and for all other purposes; and none of the
Company, the Trustee, any Authenticating Agent, any Paying Agent, any transfer
agent or 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 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 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

                                       41
<PAGE>

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.

                                  ARTICLE VIII
                            SECURITYHOLDERS' MEETINGS

            Section 8.01 Purposes of Meetings.

            A meeting of Securityholders may be called at any time and from time
to time pursuant to the provisions of this Article VIII for any of the following
purposes:

            (a) to give any notice to the Company or to the Trustee, or to give
any directions to the Trustee, or to consent to the waiving of any default
hereunder and its consequences, or to take any other action authorized to be
taken by Securityholders pursuant to any of the provisions of Article V;

            (b) to remove the Trustee and nominate a successor trustee pursuant
to the provisions of Article VI;

            (c) to consent to the execution of an indenture or indentures
supplemental hereto pursuant to the provisions of Section 9.02; or

            (d) to take any other action authorized to be taken by or on behalf
of the holders of any specified aggregate principal amount of such Debt
Securities under any other provision of this Indenture or under applicable law.

            Section 8.02 Call of Meetings by Trustee.

            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 The City of New York, the Borough of Manhattan, 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 the Debt Securities Register. Such notice shall be mailed not less than 20
nor more than 180 days prior to the date fixed for the meeting.

                                       42
<PAGE>

            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% in aggregate principal amount of the Debt
Securities, as the case may be, then outstanding, shall 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 Indianapolis, Indiana 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.

            To be entitled to vote at any meeting of Securityholders, a Person
shall be (a) a holder of one or more Debt Securities or (b) a Person appointed
by an instrument in writing as proxy by a holder of one or more Debt Securities.
The only Persons who shall be entitled to be present or to speak at any meeting
of Securityholders shall be the Persons entitled to vote at such meeting and
their counsel and any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

            Section 8.05 Regulations.

            Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Securityholders, in regard to proof of the holding of Debt Securities and of the
appointment of proxies, and in regard to the appointment and 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, unless the meeting shall have been called by the
Company or by Securityholders as provided in Section 8.03, in which case the
Company or the Securityholders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting shall be elected by majority vote at the meeting.

            Subject to the provisions of Section 7.04, at any meeting each
holder of Debt Securities with respect to which such meeting is being held or
proxy therefor shall be entitled to one vote for each $1,000 principal amount of
Debt Securities held or represented by such holder; provided, however, that no
vote shall be cast or counted at any meeting in respect of any Debt Security
challenged as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman of the meeting shall have no right to vote other than
by virtue of Debt Securities held by such chairman or instruments in writing as
aforesaid duly designating such chairman as the Person to vote on behalf of
other Securityholders. Any meeting of Securityholders duly called pursuant to
the provisions of Section 8.02 or 8.03 may be adjourned from time to time by a
majority of those present, whether or not constituting a quorum, and the meeting
may be held as so adjourned without further notice.

Securities held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the

secretary of the meeting their verified written reports in triplicate of all
votes cast at the meeting. A record in duplicate of the proceedings of each

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 provided in Section 8.02. The record

            Any record so signed and verified shall be conclusive evidence of
the matters therein stated.

            Section 8.07 Quorum; Actions.

            The Persons entitled to vote a majority in aggregate principal
amount of the Debt Securities then outstanding shall constitute a quorum for a
meeting of Securityholders; provided, however, that if any action is to be taken
at such meeting with respect to a consent, waiver, request, demand, notice,
authorization, direction or other action which may be given by the holders of
not less than a specified percentage in aggregate principal amount of the Debt
Securities then outstanding, the Persons holding or representing such specified
percentage in aggregate principal amount of the Debt Securities then outstanding
will constitute a quorum. In the absence of a quorum within 30 minutes of the
time appointed for any such meeting, the meeting shall, if convened at the
request of Securityholders, be dissolved. In any other case, the meeting may be
adjourned for a period of not less than 10 days as determined by the permanent
chairman of the meeting prior to the adjournment of such meeting. In the absence
of a quorum at any such adjourned meeting, such adjourned meeting may be further
adjourned for a period of not less than 10 days as determined by the permanent
chairman of the meeting prior to the adjournment of such adjourned meeting.
Notice of the reconvening of any adjourned meeting shall be given as provided in
Section 8.02, except that such notice need be given only once not less than five
days prior to the date on which the meeting is scheduled to be reconvened.
Notice of the reconvening of an adjourned meeting shall state expressly the
percentage, as provided above, of the aggregate principal amount of the Debt
Securities then outstanding which shall constitute a quorum.

            Except as limited by the proviso in the first paragraph of Section
9.02, any resolution 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 a majority in

                                       44
<PAGE>

aggregate principal amount of the Debt Securities then outstanding; provided,
however, that, except as limited by the proviso in the first paragraph of
Section 9.02, any resolution with respect to any consent, waiver, request,
demand, notice, authorization, direction or other action that this Indenture
expressly provides may be given by the holders of not less than a specified
percentage in outstanding principal amount of the Debt Securities may be adopted
at a meeting or an adjourned meeting duly reconvened and at which a quorum is
present as aforesaid only by the affirmative vote of the holders of not less
than such specified percentage in aggregate principal amount of the Debt
Securities then outstanding.

            Any resolution passed or decision taken at any meeting of holders of
Debt Securities duly held in accordance with this Section shall be binding on
all the Securityholders, whether or not present or represented at the meeting.

                             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, 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 then outstanding;

            (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

                                       45
<PAGE>

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
Section) 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 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.

            With the consent (evidenced as provided in Section 7.01) of the
holders of a majority in aggregate principal amount of the Debt Securities at
the time outstanding affected by such supplemental indenture, 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 the consent of the holders of each Debt Security then
outstanding and affected thereby, (i) change the Maturity Date of any Debt
Security, or reduce the principal amount thereof or any premium thereon, or
reduce the rate (or manner of calculation of the rate) or extend the time of
payment of interest thereon, or reduce (other than as a result of the maturity
or earlier redemption of any such Debt Security in accordance with the terms of
this Indenture and such Debt Security) or increase the aggregate principal
amount of Debt Securities then outstanding, or change any of the redemption

                                       46
<PAGE>

provisions, or make the principal thereof or any interest or premium thereon
payable in any coin or currency other than United States Dollars, or impair or
affect the right of any Securityholder to institute suit for payment thereof, 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 the trustee of the Trust,
such supplemental indenture shall not be effective until the holders of a
majority in aggregate liquidation amount of the outstanding Capital 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
outstanding Capital 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 (and
holders of Capital Securities, if required) 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 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.

            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

                                       47
<PAGE>

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,

                                    ARTICLE X
                            REDEMPTION OF SECURITIES

            Section 10.01 Optional Redemption.

            The Company shall have the right, subject to the receipt by the
Company of the prior approval from the Federal Reserve, if then required under
applicable capital guidelines or policies of the Federal Reserve, to redeem the
Debt Securities, in whole or (provided that all accrued and unpaid interest has
been paid on all Debt Securities for all Interest Periods terminating on or
prior to such date) from time to time in part, on any Interest Payment Date on
or after November 23, 2009 (each, an "Optional Redemption Date"), at the
Optional Redemption Price.

            Section 10.02 Special Event Redemption.

            If a Special Event shall occur and be continuing, the Company shall
have the right, subject to the receipt by the Company of prior approval from the
Federal Reserve, if then required under applicable capital guidelines or
policies of the Federal Reserve, to redeem the Debt Securities, in whole but not
in part, at any time within 90 days following the occurrence of such Special
Event (the "Special Redemption Date"), at the Special Redemption Price.

            Section 10.03 Notice of Redemption; Selection of Debt Securities.

            In case the Company shall desire to exercise the right to redeem
all, or, as the case may be, any part of the Debt Securities, it shall fix a
date for redemption and shall mail, or cause the Trustee to mail (at the expense
of the Company), a notice of such 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

                                       48
<PAGE>

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
price (or manner of calculation of the 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 Optional 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 such date
all the Debt Securities so called for redemption at the applicable price
therefor, together with unpaid interest accrued to such date.

            The Company will give the Trustee notice not less than 45 nor more
than 75 days prior to the date fixed for redemption as to the 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 related Optional
Redemption Date or Special Redemption Date (as the case may be) and at the place
or places stated in such notice at the applicable price therefor, together with
unpaid interest accrued thereon to said Optional Redemption Date or the Special
Redemption Date (as the case may be), and on and after said Optional Redemption
Date or the Special Redemption Date (as the case may be) (unless the Company
shall default in the payment of such Debt Securities at the redemption price,
together with unpaid interest accrued thereon 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 price
therefor, together with unpaid interest, if any, accrued thereon to said
Optional Redemption Date or the Special Redemption Date (as the case may be);
provided, however, that interest payable on any Interest Payment Date on or
prior to said Optional Redemption Date or the Special Redemption Date will be
paid to the holders on the relevant regular record date.

                                       49
<PAGE>

            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.

successors) authorized to acquire and operate the same; provided, however, that
the Company hereby covenants and agrees that (i) upon any such consolidation,
merger (where the Company is not the surviving corporation), sale, conveyance,
transfer or other disposition, the successor entity shall be a corporation
organized and existing under the laws of the United States or any state thereof
or the District of Columbia (unless such corporation has (1) agreed to make all
payments due in respect of the Debt Securities or, if outstanding, the Trust
Securities and the Capital Securities Guarantee without withholding or deduction
for, or on account of, any taxes, duties, assessments or other governmental
charges under the laws or regulations of the jurisdiction of organization or
residence (for tax purposes) of such corporation or any political subdivision or
taxing authority thereof or therein unless required by applicable law, in which
case such corporation shall have agreed to pay such additional amounts as shall
be required so that the net amounts received and retained by the holders of such
Debt Securities or Trust Securities, as the case may be, after payment of all
taxes (including withholding taxes), duties, assessments or other governmental
charges, will be equal to the amounts that such holders would have received and
retained had no such taxes (including withholding taxes), duties, assessments or
other governmental charges been imposed, (2) irrevocably and unconditionally
consented and submitted to the jurisdiction of any United States federal court
or New York state court, in each case located in the Borough of Manhattan, The
City of New York, in respect of any action, suit or proceeding against it
arising out of or in connection with this Indenture, the Debt Securities, the
Capital Securities Guarantee or the Declaration and irrevocably and
unconditionally waived, to the fullest extent permitted by law, any objection to
the laying of venue in any such court or that any such action, suit or
proceeding has been brought in an inconvenient forum and (3) irrevocably
appointed an agent in The City of New York for service of process in any action,
suit or proceeding referred to in clause (2) above) and such corporation
expressly assumes all of the obligations of the Company under the Debt
Securities, this Indenture, the Capital Securities Guarantee and the Declaration
and (ii) after giving effect to any such consolidation, merger, sale,
conveyance, transfer or other disposition, no Default or Event of Default shall
have occurred and be continuing.

            Section 11.02 Successor Entity to be Substituted.

            In case of any such consolidation, merger, sale, conveyance,

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 corporation shall succeed
to and be substituted for the Company, with the 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 corporation 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 corporation 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 corporation 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,

an Opinion of Counsel as conclusive evidence 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.

the Company in accordance with the provisions of Section 12.04, or (2) paid to
any state or to the District of Columbia pursuant to its unclaimed property or
similar laws, and if in the case of either clause (a) or (b) above the Company
shall also pay or cause to be paid all other sums payable hereunder by the
Company, then this Indenture shall cease to be of further effect except for the
provisions of Sections 2.05, 2.06, 3.01, 3.02, 3.04, 6.06, 6.09 and 12.04

6.09 and 12.04 shall survive, and the Trustee, on demand of the Company
accompanied by 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, and at the cost and
expense of the Company, shall execute proper instruments acknowledging

            Subject to the provisions of Section 12.04, all moneys deposited
with the Trustee pursuant to Section 12.01 shall be held in trust and applied by
it to the payment, either directly or through any Paying Agent (including the
Company if acting as its own Paying Agent), to the holders of the 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, premium,
if any, and interest.

            Section 12.03 Paying Agent to Repay Moneys Held.

Trustee, and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys.

            Section 12.04 Return of Unclaimed Moneys.

            Any moneys deposited with or paid to the Trustee or any Paying Agent
for payment of the principal of and premium, if any, or interest on Debt
Securities and not applied but remaining unclaimed by the holders of Debt
Securities for two years after the date upon which the principal 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.

            Subject to Article XI, the Company will have the right at all times

            Section 14.12 Acknowledgment of Rights.

            The Company acknowledges that, with respect to any Debt Securities
held by the Trust or a trustee of the Trust, if such trustee of the Trust fails
to enforce its rights under this Indenture as the holder of Debt Securities held
as the assets of the Trust after the holders of a majority in aggregate
liquidation amount of the outstanding Capital Securities of the Trust have so
directed in writing such 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 trustee's rights under this
Indenture without first instituting any legal proceedings against such 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, on or principal of the Debt
Securities on the date such interest, premium, if any, or principal is otherwise
due and payable (or, in the case of redemption, on the related Optional
Redemption Date or the Special Redemption Date (as the case may be)), the
Company acknowledges that a holder of outstanding 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

                                       55

holder on or after the respective due date (or Optional Redemption Date or
Special Redemption Date (as the case may be)) 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 holder'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 or any Securityholder when such payment is prohibited
by the preceding paragraph of this Section, 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 trustee) notify the
Trustee in writing within 90 days of such payment of the amounts then due and
owing on the 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,

                                       56
<PAGE>

winding-up, 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, winding-up, 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, 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, transfer or other
disposition 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 if such other corporation shall,
as a part of such

                                       57

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
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 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 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

                                       59
<PAGE>

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 or any other Person.

                                       of
                                 Horizon Bancorp

            Horizon Bancorp, a bank holding company incorporated in the State of
Indiana (the "Company", which term includes any successor permitted under the
Indenture (as defined herein)), for value received, promises to pay to
Wilmington Trust Company, not in its individual capacity but solely as
Institutional Trustee for Horizon Bancorp Capital Trust II, a Delaware statutory
trust, or registered assigns, the principal amount of TEN MILLION THREE HUNDRED
TEN THOUSAND Dollars ($10,310,000) on November 23, 2034 (the "Maturity Date")
(or any Optional Redemption Date or the Special Redemption Date, each as defined
herein, or any earlier date of acceleration of the maturity of this Debt
Security), and to pay interest on the outstanding principal amount of this Debt
Security from October 21, 2004, or from the most recent Interest Payment Date
(as defined below) to which interest has been paid or duly provided for,
quarterly (subject to deferral as set forth herein) in arrears on February 23,
May 23, August 23 and November 23 of each year, commencing on February 23, 2005
(each, an "Interest Payment Date"), at a rate per annum, which, with respect to
any Interest Period (as defined in the Indenture), will be equal to LIBOR (as
defined in the Indenture), as determined on the LIBOR Determination Date (as
defined in the Indenture) for such Interest Period (or, in the case of the first
Interest Period, will be 2.10%), plus 1.95% (the "Interest Rate") (provided that
the Interest Rate for any Interest Period may not exceed the highest rate
permitted by New York law, as the same may be modified by United States law of
general application) until the principal hereof shall have been paid or duly
provided for, 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 then applicable
Interest Rate, compounded quarterly. The amount of interest payable for any
Interest Period shall be computed on the basis of a 360-day year and the actual
number of days elapsed in such Interest Period.

            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 the Indenture) is

                                       A-3

<PAGE>

registered at the close of business on the "regular record date" for such
interest installment, which shall be the fifteenth day prior to such Interest
Payment Date, whether or not such day is a Business Day (as defined herein). Any
such interest installment (other than Deferred Interest (as defined herein)) not
punctually paid or duly provided for shall forthwith cease to be payable to the
holders on such regular record date and may be paid to the Person in whose name
this Debt Security (or one or more Predecessor 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 holders
of the Debt Securities not less than 10 days prior to such special record date,
all as more fully provided in the Indenture.

            Payment of the principal of and premium, if any, and interest on
this Debt Security due on the Maturity Date, any Optional Redemption Date or the
Special Redemption Date, as the case may be, shall be made in immediately
available funds against presentation and surrender of this Debt Security at the
office or agency of the Trustee maintained for that purpose in Wilmington,
Delaware, or at the office or agency of any other Paying Agent appointed by the
Company maintained for that purpose in Wilmington, Delaware or Indianapolis,
Indiana. Payment of interest on this Debt Security due on any Interest Payment
Date other than the Maturity Date, any Optional Redemption Date or the Special
Redemption Date, as the case may be, shall be made at the option of the Company
by check mailed to the holder thereof at such address as shall appear in the
Debt Security Register or by wire transfer of immediately available funds 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, payment of the principal of and premium, if any, and interest on this
Debt Security shall be made in immediately available funds when due at such
place and to such account as may be designated by the Institutional Trustee. All
payments in respect of this Debt Security shall be payable in any coin or
currency of the United States of America that at the time of payment is legal
tender for payment of public and private debts.

            Notwithstanding anything to the contrary contained herein, if any
Interest Payment Date, other than the Maturity Date, any Optional 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, and additional interest will
accrue for each day that such payment is delayed as a result thereof. If the
Maturity Date, any Optional 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.

            So long as no Event of Default 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, together with all previous
and further consecutive extensions thereof, is referred to herein as an
"Extension Period"). No Extension Period may end on a date other than an
Interest Payment Date or extend beyond the Maturity Date, any Optional
Redemption Date or the Special Redemption Date, as the case may be. During any
Extension Period, interest will continue to accrue on the Debt Securities, and

                                       A-4

<PAGE>

interest on such accrued interest (such accrued interest and interest thereon
referred to herein as "Deferred Interest") will accrue at an annual rate equal
to the Interest Rate applicable during such Extension Period, compounded
quarterly from the date such Deferred Interest would have been payable were it
not for the Extension Period, to the extent permitted by applicable law. No
interest or Deferred Interest (except any Additional Amounts (as defined in the
Indenture) 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 Extension Period,
the Company shall pay all Deferred Interest then accrued and unpaid on the Debt
Securities; provided, however, that during any Extension Period, the Company may
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

rank in all respects pari passu with or junior in respect to the Capital
Securities Guarantee (other than (a) repurchases, redemptions or other
acquisitions of shares of capital stock of the Company (A) 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, (B) in

Period, (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

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 to such stock). Prior to the termination of any
Extension Period, the Company may further extend such Extension Period,
provided, that no Extension Period (including all previous and further
consecutive extensions that are part of such Extension Period) shall exceed 20
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 or extend an Extension Period at
least one Business Day prior to the regular record date applicable to the next
succeeding Interest Payment 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 (as defined in the Indenture),
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

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 diligence, presentment, demand for payment,
notice of nonpayment, notice of protest, and all other demands and 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 (collectively, the "Debt Securities"), all issued or
to be issued pursuant to an Indenture (the "Indenture"), dated as of October 21,
2004, 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 of which this Debt
Security is a part.

            Upon the occurrence and continuation of a Tax Event, an Investment
Company Event or a Capital Treatment Event (each, a "Special Event"), the
Company shall have the right to redeem this Debt Security, at its option, in
whole with all other Debt Securities but not in part, at any time, within 90
days following the occurrence of such Special Event (the "Special Redemption
Date"), at the Special Redemption Price (as defined herein).

            The Company shall also have the right to redeem this Debt Security
at its option, in whole or (provided that all accrued and unpaid interest has
been paid on all Debt Securities for all Interest Periods terminating on or
prior to such date) from time to time in part, on any Interest Payment Date on
or after November 23, 2009 (each, an "Optional Redemption Date"), at the
Optional Redemption Price (as defined herein).

            Any redemption pursuant to the preceding two paragraphs will be
made, subject to 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' prior written notice. If the Debt
Securities are only partially redeemed by the Company, the Debt Securities will
be redeemed pro rata or by any other method utilized by the Trustee. 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.

            "Optional Redemption Price" means an amount in cash equal to 100% of
the principal amount of this Debt Security being redeemed plus unpaid interest
accrued thereon to the related Optional Redemption Date.

            "Special Redemption Price" means, with respect to the redemption of
this Debt Security following a Special Event, an amount in cash equal to
104.000% of the principal amount of this Debt Security to be redeemed prior to
November 23, 2005 and thereafter equal to the percentage of the principal amount
of this Debt Security that is specified below for the Special Redemption Date
plus, in each case, unpaid interest accrued thereon to the Special Redemption
Date:

</TABLE>

            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, and, in certain cases, shall ipso facto become, due and payable, and
upon any such declaration of acceleration shall become due and payable, in each
case, 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 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) change the Maturity Date of any Debt Security, or reduce the
principal amount thereof or any premium thereon, or reduce the rate (or manner
of calculation of the rate) or extend the time of payment of interest thereon,
or reduce (other than as a result of the maturity or earlier redemption of any
such Debt Security in accordance with the terms of the Indenture and such Debt
Security) or increase the aggregate principal amount of Debt Securities then
outstanding, or change any of the redemption provisions, or make the principal
thereof or any interest or premium thereon payable in any coin or currency other
than United States Dollars, or impair or affect the right of any holder to
institute suit for 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 the holders of all 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) a default in payments due in respect of any of the Debt Securities,
(b) in respect of covenants or provisions of the Indenture which cannot be
modified or amended without the consent of the holder of each Debt Security
affected, or (c) in respect of the covenants of the Company relating to its
ownership of Common Securities of the Trust. Any such consent or waiver by the
holder of this Debt Security (unless revoked as provided in the Indenture) shall
be conclusive and binding upon such holder and upon

                                       A-9

<PAGE>

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 make 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 holder
hereof on the Debt Security Register (as defined in the Indenture) of the
Company, upon surrender of this Debt Security for registration of transfer at
the office or agency of the Trustee in Wilmington, Delaware, or at any other
office or agency of the Company in Wilmington, Delaware or Indianapolis,
Indiana, accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company or the Trustee duly executed by the 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
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 or
the Trustee may require payment of a sum sufficient to cover any tax, fee or
other governmental charge payable in relation thereto as specified in the
Indenture.

            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 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 the principal of and premium, if any, and
interest on this Debt Security and for all other purposes, and none of the
Company, the Trustee, any Authenticating Agent, any Paying Agent, any transfer
agent or any Debt Security registrar shall be affected by any notice to the
contrary.

            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 different authorized
denominations, as requested by the holder surrendering the same.

            The Debt Securities are issuable only in registered certificated
form without coupons.

            No recourse shall be had for the payment of the principal of or
premium, if any, or 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, director, employee or
agent, past, present or future, as such, of the Company or of any predecessor or
successor corporation of the Company, 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.
