Trust, and proposes to invest the proceeds from such offering, together with
the proceeds of the issuance and sale by the Trust to the Company of
$6,185,575 aggregate liquidation amount of its Common Securities, in the

Indenture a valid and binding instrument in accordance with its terms, and to
make the Debentures, when executed by the Company and authenticated and
delivered by the Trustee, the valid and binding obligations of the Company,

Supplemental Indenture has been duly authorized in all respects:

     NOW THEREFORE, in consideration of the purchase of the Debentures by the
Holders thereof, and for the purpose of setting forth, as provided in the
Indenture, the form and substance of the Debentures and the additional terms,
provisions and conditions thereof, the Company covenants and agrees with the

principal of the Debentures for purposes of the Indenture) shall be the date
on which the Debentures mature and on which the principal thereof shall be due
and payable together with all accrued and unpaid interest thereon (including

     Section 2.3. Form And Payment.

     Except as provided in Section 2.4, the Debentures shall be issued in
fully registered certificated form without interest coupons. Principal of,

Debentures will be exchangeable for Debentures bearing identical terms and
provisions at the office or agency of the Company maintained for such purpose
as set forth in the Indenture; provided, however, that payment of interest
with respect to Debentures (other than a Global Debenture) may be made at the
option of the Company (i) by check mailed to the Holder at such address as
shall appear in the Security Register or (ii) by transfer to an account
maintained by the Person entitled thereto, provided that proper transfer
instructions have been received in writing by the relevant record date. The
Company selects New York, New York as a place of payment where the principal
of, and premium, if any, and interest on the Debentures are payable as
specified in accordance herewith, and hereby appoints The Bank of New York,
the Trustee, as registrar for the Debentures (the "Security Registrar").
Notwithstanding the foregoing, so long as the Holder of any Debentures is the
Property Trustee, the payment of the principal of, premium, if any, and
interest (including Compounded Interest and Additional Interest, if any) on
such Debentures held by the Property Trustee will be made at such place and to
such account as may be designated by the Property Trustee.

     Section 2.4. Global Debenture.

     (a) In connection with a Dissolution Event,

          (i) the Debentures in certificated form may be presented to the
     Trustee by the Property Trustee in exchange for a global Debenture in an
     aggregate principal amount equal to the aggregate principal amount of all
     outstanding Debentures (a "Global Debenture"), to be registered in the
     name of the Depositary, or its nominee, and delivered by the Trustee to
     or upon the order of the Depositary for crediting to the accounts of its
     participants pursuant to the instructions of the Administrative Trustees.
     The Company upon any such presentation shall execute a Global Debenture
     in such aggregate principal amount and deliver the same to the Trustee
     for authentication and delivery in accordance with the Indenture.
     Payments on the Debentures issued as a Global Debenture will be made to
     the Depositary; and

          (ii) if any Preferred Securities are held in non book-entry
     certificated form, the Debentures in certificated form may be presented
     to the Trustee by the Property Trustee and any Preferred Security
     Certificate which represents Preferred Securities other than Preferred
     Securities held by the Clearing Agency or its nominee ("Non Book-Entry
     Preferred Securities") will be deemed to represent beneficial interests
     in Debentures presented to the Trustee by the Property Trustee having an
     aggregate principal amount equal to the aggregate liquidation amount of
     the Non Book-Entry Preferred Securities until such Preferred Security
     Certificates are presented to the Security Registrar for transfer or
     reissuance at which time such Preferred Security Certificates will be
     cancelled and a Debenture, registered in the name of the holder of the
     Preferred Security Certificate or the transferee of the holder of such
     Preferred Security Certificate, as the case may be, with an aggregate
     principal amount equal to the aggregate liquidation amount of the
     Preferred Security Certificate cancelled, will be executed by the Company
     and delivered to the Trustee for authentication and delivery in
     accordance with the Indenture. Upon the issuance of such Debentures,
     Debentures with an equivalent aggregate principal amount that were
     presented by the Property Trustee to the Trustee will be deemed to have
     been cancelled.

<PAGE>
                                                                             6

          (b) A Global Debenture may be transferred, in whole but not in part,
     only to another nominee of the Depositary, or to a successor Depositary
     selected or approved by the Company or to a nominee of such successor
     Depositary.

          Section 2.5. Interest.

          (a) Each Debenture will bear interest at a rate of 8.10% per annum
     from November 27, 2002, until the principal thereof becomes due and
     payable, and on any overdue principal at a rate of 8.10% per annum and
     (to the extent that payment of such interest is enforceable under
     applicable law) on any overdue installment of interest at a rate of 8.10%
     per annum, compounded quarterly, payable (subject to the provisions of
     Article IV) quarterly in arrears on the 15th day of February, May, August
     and November of each year, commencing on February 15, 2003, to the Person
     in whose name such Debenture or any predecessor Debenture is registered,
     at the close of business on the regular record date for such interest
     installment, which, in respect of any Debentures of which the Property
     Trustee is the Holder or in the case of a Global Debenture, shall be the
     close of business on the Business Day next preceding that Interest
     Payment Date (as defined below). Notwithstanding the foregoing sentence,
     if the Debentures are no longer in book-entry only form, except if the
     Debentures are held by the Property Trustee, the record dates shall be
     the close of business on the February 1, May 1, August 1 and November 1
     immediately preceding the relevant Interest Payment Date, whether or not
     a Business Day.

          (b) Unless otherwise provided by the Trustee, the Paying Agent will
     calculate the amount of interest payable on the Debentures in respect of
     each Interest Period. The amount of interest payable for any Interest
     Period will be computed on the basis of a 360-day year consisting of
     twelve 30-day months and rounding the resulting figure to the nearest
     cent (with one-half cent or more being rounded upwards). The amount of
     interest payable for any partial Interest Period will be computed on the
     basis of the actual number of days elapsed during any such 30-day month.
     The determination of the amount of interest payable by Paying Agent will
     (in the absence of willful default, bad faith or manifest error) be
     final, conclusive and binding on all concerned.

          (c) All certificates, communications, opinions, determinations,
     calculations, quotations and decisions given, expressed, made or obtained
     for the purposes of the provisions relating to the payment and
     calculation of interest on the Debentures, whether by the Trustee or
     Paying Agent, will (in the absence of willful default, bad faith or
     manifest error) be binding on the Trust, the Company, the Trustee and all
     of the holders of the Debentures, and no liability will (in the absence
     of willful default, bad faith or manifest error) attach to the Trustee or
     Paying Agent in connection with the exercise or non-exercise by any of
     them of their powers, duties and discretion.

          (d) In the event that any date on which interest is payable on the
     Debentures is not a Business Day, then payment of interest payable on
     such date will be made on the next succeeding day which is a Business
     Day, except that, if such Business Day is in the next succeeding calendar
     year, such payment shall be made on the immediately preceding Business
     Day, in each case with the same force and effect as if made on such date
     (each date on which interest is actually payable, an "Interest Payment
     Date").

<PAGE>
                                                                             7

          (e) If at any time the Trust is required to pay any taxes, duties,
     assessments or governmental charges of whatever nature (other than
     withholding taxes) imposed by the United States, or any other taxing
     authority, then the Company will pay such Additional Interest
     ("Additional Interest") on the Debentures held by the Property Trustee as
     shall be required so that the net amounts received and retained by the
     Trust after paying such taxes, duties, assessments or other governmental
     charges will be equal to the amounts the Trust would have received had
     the Trust not been subject to such taxes, duties, assessments or other
     government charges imposed.

          (f) All percentages resulting from any calculations referred to in
     this Second Supplemental Indenture will be rounded, if necessary, to the
     nearest multiple of 1/100 of 1% and all U.S. dollar amounts used in or
     resulting from such calculations will be rounded to the nearest cent
     (with one-half cent or more being rounded upwards).

                                 ARTICLE III
                         REDEMPTION OF THE DEBENTURES

right upon not less than 30 nor more than 60 days' notice, to redeem the
Debentures, in whole, but not in part, for cash within 90 days following the

then required for such redemption, on such later date as promptly practicable
after such approval is obtained) at the Redemption Price.

     Section 3.2. Capital Treatment Event of Redemption.

     Subject to the prior approval of the Federal Reserve, if such approval is
then required under applicable law, rules, guidelines or policies, if at any
time a Capital Treatment Event shall occur and be continuing, the Company
shall have the right, upon not less than 30 nor more 60 days' notice, to
redeem the Debentures, in whole, but not in part, for cash within 90 days
following the occurrence of such Capital Treatment Event (or, if the approval
of the Federal Reserve is then required for such redemption, on such later
date as promptly as practicable after such approval is obtained) at the
Redemption Price.

     Section 3.3. Investment Company Event of Redemption.

     Subject to the prior approval of the Federal Reserve, if such approval is
then required under applicable law, rules, guidelines or policies, if at any
time a Investment Company Event shall occur and be continuing, the Company
shall have the right, upon not less than 30 nor more 60 days' notice, to
redeem the Debentures, in whole, but not in part, for cash within 90 days
following the occurrence of such Investment Company Event (or, if the approval
of the Federal Reserve is then required for such redemption, on such later
date as promptly as practicable after such approval is obtained) at the
Redemption Price.

     Section 3.4. Optional Redemption By Company.

     (a) Subject to the prior approval of the Federal Reserve, if such
approval is then required under applicable law, rules, guidelines or policies,
the Company shall have the right to redeem the Debentures, in whole or in

nor more than 60 days' notice at the Redemption Price.

     (b) If the Debentures are only partially redeemed pursuant to this
Section 3.4, the Debentures will be redeemed pro rata or by lot or by any
other method utilized by the Security Registrar; provided, that if at the time
of redemption the Debentures are registered as a Global Debenture, the
Depositary shall determine, in accordance with its procedures, the principal
amount of such Debentures beneficially held by each Holder of Debentures to be
redeemed.

     Section 3.5. No Sinking Fund.

     The Debentures are not entitled to the benefit of any sinking fund.

                                  ARTICLE IV
                     EXTENSION OF INTEREST PAYMENT PERIOD

     Section 4.1. Extension of Interest Payment Period.

     So long as no Event of Default has occurred and is continuing, the
Company shall have the right, at any time and from time to time during the
term of the Debentures, to defer payments of interest on the Debentures by
extending the interest payment period of such Debentures for a period not
exceeding 20 consecutive quarterly periods (the "Extension Period"), during
which Extension Period no interest shall be due and payable; provided that no
Extension Period shall end on a date other than an Interest Payment Date or
extend beyond the Maturity Date. To the extent permitted by applicable law,
interest, the payment of which has been deferred because of the extension of
the interest payment period pursuant to this Section 4.1, will bear interest
thereon at a rate of 8.10% per annum compounded quarterly for each quarterly
period of the Extension Period ("Compounded Interest"). At the end of the
Extension Period, the Company shall pay all interest accrued and unpaid on the
Debentures, including any Additional Interest and Compounded Interest
(together, "Deferred Interest") that shall be payable to the Holders in whose
names the Debentures are registered in the Security Register on the record
date relating to the Interest Payment Date on which the Extension Period ends.
Before the termination of any Extension Period, the Company may further defer
payments of interest by further extending such period, provided that such
period, together with all such previous and further extensions within such
Extension Period, shall not exceed 20 consecutive quarterly periods or extend
beyond the Maturity Date of the Debentures. Upon the termination of any
Extension Period and the payment of all Deferred Interest then due, the
Company may commence a new Extension Period, subject to the foregoing
requirements. No interest shall be due and payable during an Extension Period,
except at the end thereof. The provisions of this Section 4.1 and Section 4.2
shall apply to the Debentures in lieu of Section 3.11 of the Indenture.

     Section 8.2. Covenants As To The Trust.

     In the event Debentures are issued to the Trust or a trustee of such
trust in connection with the issuance of Trust Securities by the Trust, for so
long as such Trust Securities remain outstanding, the Company (i) will
maintain 100% direct or indirect ownership of the Common Securities of the
Trust; provided, however, that any successor of the Company, permitted
pursuant to Article X of the Indenture, may succeed to the Company's ownership
of such Common Securities, (ii) will use commercially reasonable efforts to
cause the Trust (a) to remain a grantor trust, except in connection with a
distribution of Debentures to the holders of Trust Securities in liquidation
of the Trust, the redemption of all of the Trust Securities of the Trust, or
certain mergers, consolidations or amalgamations, each as permitted by the
Declaration, and (b) to otherwise continue to be classified as a grantor trust
and not an association taxable as a corporation for United States federal
income tax purposes and (iii) will not cause, as sponsor of the Trust, or
permit, as holder of the Common Securities, the dissolution, winding-up or
termination of the Trust, except in connection with a distribution of the
Debentures as provided in the Declaration and in connection with certain
mergers, consolidations or amalgamations. The provisions of this Section 8.2
shall apply to the Debentures in lieu of the second paragraph of Section 10.7
of the Indenture.

                                 MISCELLANEOUS

     Section 9.1. Ratification of Indenture.

     The Indenture, as supplemented by this Second Supplemental Indenture, is
in all respects ratified and confirmed, and this Second Supplemental Indenture
shall be deemed part of the Indenture in the manner and to the extent herein
and therein provided.

     Section 9.2. Acknowledgment of Rights.

     The Company acknowledges that, with respect to any Debentures held by the
Trust or a trustee thereof, if the Property Trustee of such Trust fails to
enforce its rights under this Second Supplemental Indenture or the Indenture
as the Holder of the Debentures held as the assets of the Trust, any holder of
Preferred Securities may institute legal proceedings directly against the
Company to enforce such Property Trustee's rights under this Second
Supplemental Indenture or the Indenture without first instituting any legal
proceedings against such Property Trustee or any other person or entity.
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
principal of, premium, if any, or interest on the Debentures when due, the
Company acknowledges that a holder of Preferred Securities may institute a
direct action for enforcement of payment to such holder of the principal of,
premium, if any, or interest on the Debentures having a principal amount equal
to the aggregate liquidation amount of the Preferred Securities of such holder
on or after the respective due date specified in the Debentures.

     In case any provision of this Second Supplemental Indenture or in the
Debentures shall be invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

     Section 9.6. Counterparts.

     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

     MBNA CORPORATION, a corporation organized and existing under the laws of
the state of Maryland (hereinafter called the "Company", which term includes
any successor corporation under the Indenture hereinafter referred to), for
value received, hereby promises to pay to The Bank of New York, as Property
Trustee for MBNA Capital E, a statutory trust formed under the laws of the
State of Delaware (the "Property Trustee"), or registered assigns, the
principal sum of $206,185,575 on February 15, 2033, and to pay interest on
said principal sum from November 27, 2002 or from the most recent Interest
Payment Date on which interest has been paid or duly provided for, quarterly
(subject to deferral as set forth herein) in arrears on the February 15, May
15, August 15 and November 15 of each year, commencing on February 15, 2003
(each such date, an "Interest Payment Date") at the rate of 8.10% per annum
until the principal hereof shall have become due and payable, plus Additional
Interest, if any, until the principal hereof is paid or duly provided for or
made available for payment 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 the rate of
8.10% per annum, compounded quarterly. The amount of interest payable on any
Interest Payment Date (as defined above) shall be calculated as provided in
the Indenture. In the event that any date on which interest is payable on this
Debenture is not a Business Day, then payment of the interest payable on such
date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on the date the payment was
originally payable. 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 Debenture (or one or more
Predecessor Securities, as defined in the Indenture) is registered at the
close of business on the Regular Record Date for such interest installment,
which shall be, if the Debentures are not in book entry only form, except if
the Debentures are held by the Property Trustee, the close of business on the
February 1, May 1, August 1 and November 1 immediately preceding the relevant
Interest Payment Date, whether or not a Business Day. In the case of a Global
Debenture or any Debentures of which the Property Trustee is the Holder, such
regular record date shall be the close of business on the Business Day next
preceding the applicable Interest Payment Date. Any such interest installment
not punctually paid or duly provided for shall forthwith cease to be payable
to the registered Holders on such Regular Record Date and may either be paid
to the Person in whose name this Debenture (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to the registered Holders not less than 10 days prior
to such Special Record Date, or be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange or
interdealer quotation system on which the Debentures may be listed or traded,
and upon such notice as may be required by such exchange or self-regulatory
organization, all as more fully provided in the Indenture.

     Payment of principal of (and premium, if any) and interest (including
Compounded Interest and Additional Interest, if any) on this Debenture will be
payable at the office or agency of the Trustee maintained for that purpose in
the United States, 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; provided, however, that at the option of the Company payment of
interest may be made (i) by check mailed to the Registered Holder at such
address as shall appear in the Securities Register or (ii) by wire transfer to
an account designated by a Holder in writing not less than ten days prior to
the date of payment. Notwithstanding the foregoing, so long as the Holder of
this Debenture is the Property Trustee, the payment of the principal of,
premium, if any, and interest on this Debenture will be made at the place and
to the account as may be designated by the Property Trustee.

     The indebtedness evidenced by this Debenture is, to the extent provided
in the Indenture, subordinate and junior in right of payment to the prior
payment in full of all Senior Indebtedness, and this Debenture is issued
subject to the provisions of the Indenture with respect thereto. Each Holder
of this Debenture, by accepting the same, (a) agrees to and shall be bound by
such provisions, (b) authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate
the subordination so provided and (c) appoints the Trustee his
attorney-in-fact for any and all such purposes. Each Holder hereof, by his
acceptance hereof, 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 or creditor upon said provisions.

     Reference is hereby made to the further provisions of this Debenture set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

     This Debenture shall not be entitled to any benefit under the Indenture
or be valid or obligatory for any purpose until the Certificate of
Authentication hereon has been executed by the Trustee referred to on the
reverse hereof by manual signature.

                        (FORM OF REVERSE OF DEBENTURE)

     This Debenture is one of a duly authorized series of debt securities of
the Company (herein called the "Debentures"), issued and to be issued in one
or more series under a Junior Subordinated Indenture, dated as of December 18,
1996, duly executed and delivered between the Company and The Bank of New
York, as Trustee (herein called the "Trustee") (the "Indenture," such term,
unless the context specifies otherwise, to include any supplement including
the Second Supplemental Indenture (as defined below)), as supplemented by the
Second Supplemental Indenture, dated as of November 27, 2002, between the
Company and the Trustee (the "Second Supplemental Indenture"), to which
Indenture and all indentures supplemental thereto reference is hereby made for
a description of the respective rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the Holders
of the Debentures, and of the terms upon which the Debentures are, and are to
be, authenticated and delivered. This Debenture is one of the series
designated on the face hereof and is limited in aggregate principal amount as
specified in said Second Supplemental Indenture.

     The Company may at any time, at its option, on or after February 15,
2008, and subject to the terms and conditions of Article XI of the Indenture
and Article III of the Second Supplemental Indenture, redeem this Debenture,
in whole at any time or in part from time to time, without premium or penalty,
at a redemption price equal to 100% of the principal amount thereof plus
accrued and unpaid interest including Additional Interest, if any, to the
Redemption Date. Any redemption pursuant to this paragraph will be made upon
not less than 30 days' nor more than 60 days' notice. If the Debentures are
only partially redeemed by the Company pursuant to an Optional Redemption, the
Debentures will be redeemed pro rata or by lot or by any other method utilized
by the Security Registrar; provided that if, at the time of redemption, the
Debentures are registered as a Global Debenture, the Depositary shall
determine the principal amount of such Debentures beneficially held by each
Debenture holder to be redeemed in accordance with its procedures.

     Upon the occurrence and during the continuation of a Tax Event,
Investment Company Event or a Capital Treatment Event in respect of a Trust,
the Company may, at its option, at any time within 90 days of the occurrence
of such Tax Event, Investment Company Event or Capital Treatment Event redeem
this Debenture, in whole but not in part, subject to the provisions of Article
XI of the Indenture and Article III of the Second Supplemental Indenture, at a
redemption price equal to 100% of the principal amount thereof plus accrued
and unpaid interest, including Additional Interest, if any, to the Redemption
Date.

     In the event of redemption of this Debenture in part only, a new
Debenture or Debentures for the unredeemed portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

     Notwithstanding the foregoing, any redemption of Debentures by the
Company shall be subject to the prior approval of the Federal Reserve, if such
approval is then required under applicable law, rules, guidelines or policies
of the Federal Reserve.

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

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the Holders of not less than a majority in aggregate
principal amount of the outstanding Securities of all series affected (acting
as one class), 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 Securities; provided, however,
that no such supplemental indenture shall without the consent of the Holders
of the outstanding Debentures affected thereby (i) change the Maturity Date,
or reduce the rate or extend the time of payment of interest (except as
contemplated by Section 4.1 of the Second Supplemental Indenture), or reduce
the principal amount thereof, or reduce any amount payable on prepayment
thereof, or make the principal thereof or any interest or premium thereon
payable in any coin or currency other than that in which any Debenture (or
premium, if any, thereon) or the interest thereon is payable according to its
terms, or impair or affect the right of any Holder to institute suit for
payment thereof; or (ii) reduce the percentage in principal amount of the
outstanding Debentures, the Holders of which are required to consent to any
such amendment to the Second Supplemental Indenture; provided, however, that
if the Debentures are held by the Property Trustee of the Trust, such
amendment shall not be effective until the holders of a majority in
liquidation amount of Trust Securities shall have consented to such amendment;
provided, further, that if the consent of the Holder of each outstanding
Debenture is required, such amendment shall not be effective until each holder
of the Trust Securities shall have consented to such amendment. The Indenture
also contains provisions permitting the Holders of a majority in aggregate
principal amount of the outstanding Securities of any series affected thereby,
on behalf of all of the Holders of the Securities of such series, to waive any
past default in the performance of any of the covenants contained in the
Indenture, or established pursuant to the Indenture with respect to such
series, and its consequences, except a default in the payment of the principal
of, premium, if any, or interest on any of the Securities of such series. Any
such consent or waiver by the registered Holder of this Debenture (unless
revoked as provided in the Indenture) shall be conclusive and binding upon
such Holder and upon all future Holders and owners of this Debenture and of
any Debenture issued in exchange therefor 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 Debenture.

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

exceeding 20 consecutive quarterly periods (an "Extension Period") during
which Extension Period no interest shall be due and payable; provided that no
Extension Period shall end on a date other than an Interest Payment Date or
extend beyond the Maturity Date. Before

the termination of any Extension Period, the Company may further defer
payments of interest by further extending such period, provided that such
period, together with all such previous and further extensions within such
Extension Period, shall not exceed 20 consecutive quarterly periods or extend
beyond the Maturity Date. Upon the termination of any Extension Period and the
payment of all accrued and unpaid interest and including any Additional
Interest and Compounded Interest then due, the Company may commence a new
Extension Period, subject to the foregoing requirements.

     Subject to the prior approval of the Federal Reserve if such approval is
then required under applicable law, rules, guidelines or policies of the
Federal Reserve, the Company will have the right at any time to liquidate the
Trust and cause the Debentures to be distributed to the holders of the Trust
Securities in liquidation of the Trust.

set forth, this Debenture is transferable by the registered Holder hereof on
the Security Register of the Company, upon surrender of this Debenture for
registration of transfer at the office or agency of the Trustee, 101 Barclay
Street, New York, New York 10286, accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company and the Security
Registrar duly executed by the registered Holder hereof or his or her attorney
duly authorized in writing, and thereupon one or more new Debentures 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 transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

nor any such agent shall be affected by notice to the contrary.

interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether
by virtue of any constitution, statute or rule of law, or by the enforcement
of any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issuance hereof,
expressly waived and released.

     The Debentures are issuable only in registered form without coupons in
denominations of $25.00 and any integral multiple thereof.

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

have the meanings assigned to them in the Indenture. THE INDENTURE AND THE
DEBENTURES SHALL BE
