similar tenor signed by such Holders in person or by an agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall

Trustee, and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

      (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a Person acting in other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority.

      (c) The fact and date of the execution by any Person of any such
instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient and in
accordance with such reasonable rules as the Trustee may determine.

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

      (e) Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Holder of any Security shall bind every future Holder of
the same Security and the Holder of every Security issued upon the transfer
thereof or in exchange therefor or in lieu thereof in respect of anything done
or suffered to be done by the Trustee or the Company in reliance thereon,
whether or not notation of such action is made upon such Security.

      (f) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided

                                       11
<PAGE>

that the Company may not set a record date for, and the provisions of this
paragraph shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date, provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
(as hereinafter in this Section 1.4(f) provided) by Holders of the requisite
principal amount of Outstanding Securities of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Company from setting
a new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Company, at its own
expense, shall cause notice of such record date, the proposed action by Holders
and the applicable Expiration Date to be given to the Trustee in writing and to
each Holder of Securities of the relevant series in the manner set forth in
Section 1.6.

      The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.2, (iii) any request to institute
proceedings referred to in Section 5.7(2) or (iv) any direction referred to in
Section 5.12, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date, provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 1.6.

      With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day, provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date

                                       12
<PAGE>

shall be deemed to have initially designated the 180th day after such record
date as the Expiration Date with respect thereto, subject to its right to change
the Expiration Date as provided in this paragraph. Notwithstanding the
foregoing, no Expiration Date shall be later than the 180th day after the
applicable record date.

      (g) Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

      SECTION 1.5 Notices, Etc. to Trustee and Company.

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

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

            (2) the Company by the Trustee, any Holder or any holder of Capital
      Securities shall be sufficient for every purpose (except as otherwise
      provided in Section 5.2) hereunder if in writing and mailed, first class,
      postage prepaid, to the Company addressed to it at the address of its
      principal office specified in the first paragraph of this instrument or at
      any other address previously furnished in writing to the Trustee by the
      Company.

      SECTION 1.6 Notice to Holders; Waiver.

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

                               (TITLE OF SECURITY)

No.                                                                            $

      CITIZENS BANKING CORPORATION, a corporation organized and existing under
the laws of Michigan (hereinafter called the "Company", which term includes any
successor corporation under the Indenture hereinafter referred to), for value
received, hereby promises to pay to _______, or registered assigns, the
principal sum of __________ Dollars [if the Security is a Global Security, then
insert, if applicable--, or such other principal amount as may be set forth in
the records of the Securities Registrar hereinafter referred to in accordance
with the Indenture,] on _______,__. The Company further promises to pay interest
on said principal sum from ________,____ or from the most recent interest
payment date (each such date, an "Interest Payment Date") on which interest has
been paid or duly provided for, [monthly] [quarterly] [semi-annually] [if
applicable, insert -- (subject to deferral as set forth herein)] in arrears on
[insert applicable Interest Payment Dates] of each year, commencing
__________,_______ , at the rate of ______% per annum, together with Additional
Sums, if any, as provided in Section 10.6 of the Indenture, until the principal
hereof shall have become due and payable, [if applicable, insert -- plus
Additional Interest, if any,] until the principal hereof is paid or duly
provided for or made available for payment [if applicable, insert -- 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 ____% per annum,

                                       16
<PAGE>

compounded [monthly] [quarterly] [semi-annually]]. The amount of interest
payable for any period less than a full interest period shall be computed on the
basis of twelve 30-day months and a 360-day year and the actual number of days
elapsed in a partial month in a period. The amount of interest payable for any
full interest period shall be computed by dividing the rate per annum by
[twelve][four][two]. In the event that any date on which interest is payable on
this Security is not a Business Day, then a payment of the interest payable on
such date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay), 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.
A "Business Day" shall mean any day other than (i) a Saturday or Sunday, (ii) a
day on which banking institutions in The City of New York are authorized or
required by law or executive order to remain closed or (iii) a day on which the
Corporate Trust Office of the Trustee [if applicable, insert--, or the
designated office of the Property Trustee under the Trust Agreement hereinafter
referred to for [insert name of related Citizens Trust ____,]] is closed for
business. 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 Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest installment, which shall be the [insert definition of Regular
Record Dates]. Any such interest installment not so punctually paid or duly
provided for shall forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities of this
series 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 on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.

      [If applicable, insert--So long as no Event of Default has occurred and
is continuing, the Company shall have the right at any time during the term of
this Security to defer payment of interest on this Security, at any time or from
time to time, for up to ______ consecutive [monthly] [quarterly] [semi-annual]
interest payment periods with respect to each deferral period (each an
"Extension Period"), during which Extension Periods the Company shall have the
right to make partial payments of interest on any Interest Payment Date, and at
the end of which the Company shall pay all interest then accrued and unpaid
(together with Additional Interest thereon to the extent permitted by applicable
law); provided, however, that no Extension Period shall extend beyond the Stated
Maturity of the principal of this Security; provided, further, that during any
such Extension Period, the Company shall not, and shall not permit any
Subsidiary of the Company to, (i) declare or pay any dividends or distributions
or redeem, purchase, acquire or make a liquidation payment with respect to, any
of the Company's capital stock or (ii) make any payment of principal of or
interest or premium, if any, on or repay, repurchase or redeem any debt security
of the Company that ranks pari passu with or junior in interest to this Security
or make any guarantee payments with respect to any guarantee by the Company of
the debt securities of any Subsidiaries of the Company if such guarantee ranks
pari passu in all respects with or junior in interest to this Security (other
than (a) repurchases, redemptions or other acquisitions of shares of capital
stock of the Company in connection with any employment

                                       17
<PAGE>

contract, benefit plan or other similar arrangement with or for the benefit of
any one or more employees, officers, directors or consultants, in connection
with a dividend reinvestment or shareholder stock purchase plan or in connection
with the issuance of capital stock of the Company (or securities convertible
into or exercisable for such stock) as consideration in an acquisition
transaction entered into prior to the Extension Period, (b) as a result of an
exchange or conversion of any class or series of the Company's capital stock for
any other 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 the implementation or amendment of
the Company shareholders' rights plan (or any successor thereto), or the
issuance of rights, stock or other property under any such rights plan, or the
redemption or repurchase of rights pursuant hereto, or (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock). Prior to the termination of any such Extension Period,
the Company may further extend the interest payment period, provided that no
Extension Period shall exceed consecutive [months] [quarters] [semi-annual
periods] or extend beyond the Stated Maturity of the principal of this Security.
Upon the termination of any such Extension Period and upon the payment of all
accrued and unpaid interest and any Additional Interest then due, the Company
may elect to begin a new Extension Period, subject to the above conditions. No
interest shall be due and payable during an Extension Period except at the end
thereof. The Company shall give the Issuer Trustees notice of its election to
begin any Extension Period at least one Business Day prior to the next
succeeding Interest Payment Date on which interest on this Security would be
payable but for such deferral [if applicable, insert -- or, with respect to the
Securities issued to a Citizens Trust, so long as such Securities are held by
such Citizens Trust, prior to the earlier of (i) the next succeeding date on
which Distributions on the Capital Securities would be payable but for such
deferral or (ii) the date the Property Trustee is required to give notice to any
securities exchange or other applicable self-regulatory organization or to
holders of such Capital Securities of the record date or the date such
Distributions are payable, but in any event not less than one Business Day prior
to such record date. The Property Trustee will give notice of the Company's
election to begin a new Extension Period to the holders of the Capital
Securities. For purposes hereof, the Company's Senior Indebtedness shall not be
deemed to be pari passu with this Security.

      Payment of the principal of (and premium, if any) and interest (including
Additional Interest) on this Security will be made at the office or agency of
the Company maintained for that purpose in the United States, in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts [if applicable, insert--;
provided, however, that at the option of the Company payment of interest may be
made (i) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Securities Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Securities
Register].

      The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinate and junior in right of payments to the prior payment
in full of all Senior

                                       18
<PAGE>

Indebtedness, and this Security is issued subject to the provisions of the
Indenture with respect thereto. Each Holder of this Security, by accepting the
same, (a) agrees to and shall be bound by such provisions, (b) authorizes and
directs the Trustee on his behalf to take such actions as may be necessary or
appropriate to 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 upon said provisions.

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

      Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

      IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

      SECTION 3.3 Execution, Authentication, Delivery and Dating.

      The Securities shall be executed on behalf of the Company by its President
or one of its Vice Presidents under its corporate seal reproduced or impressed
thereon and attested by its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities. At any time and from time to
time after the execution and delivery of this Indenture, the Company may deliver
Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities. If the form or terms of
the Securities of the series have been established by or pursuant to one or more
Board Resolutions as permitted by Sections 2.1 and 3.1, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall receive, and (subject to
Section 6.1) shall be fully protected in relying upon, an Opinion of Counsel
stating,

            (1) if the form of such Securities has been established by or
      pursuant to Board Resolution as permitted by Section 2.1, that such form
      has been established in conformity with the provisions of this Indenture;

            (2) if the terms of such Securities have been established by or
      pursuant to Board Resolution as permitted by Section 3.1, that such terms
      have been established in conformity with the provisions of this Indenture;
      and

            (3) that such Securities, when authenticated and delivered by the
      Trustee and issued by the Company in the manner and subject to any
      conditions specified in such Opinion of Counsel, will constitute valid and
      legally binding obligations of the Company enforceable in accordance with
      their terms, subject to bankruptcy, insolvency, fraudulent transfer,
      reorganization, moratorium and similar laws of general applicability
      relating to or affecting creditors' rights and to general equity
      principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's

                                       26
<PAGE>

own rights, duties or immunities under the Securities and this Indenture or
otherwise in a manner which is not reasonably acceptable to the Trustee.

      Notwithstanding the provisions of Section 3.1 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

      Each Security shall be dated the date of its authentication.

      No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
signatories, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.10, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

      SECTION 3.4 Temporary Securities.

      Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any denomination, substantially of the
tenor of the definitive Securities of such series in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as evidenced
by their execution of such Securities.

      If temporary Securities of any series are issued, the Company will cause
definitive Securities of such series to be prepared without unreasonable delay.
After the preparation of definitive Securities, the temporary Securities shall
be exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for that purpose
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more definitive Securities
of the same series, of any authorized denominations having the same Original
Issue Date and Stated Maturity and having the same terms as such temporary
Securities. Until so exchanged, the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

      SECTION 3.5 Global Securities.

      (a) Each Global Security issued under this Indenture shall be registered
in the name of the Depository designated for such Global Security or a nominee
thereof and delivered to such Depository or a nominee thereof or custodian
therefor, and each such Global Security shall constitute a single Security for
all purposes of this Agreement.

      (b) Notwithstanding any other provision in this Indenture, no Global
Security may be exchanged in whole or in part for Securities registered, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depository for such Global Security or a nominee
thereof unless (a) such Depository advises the Trustee in writing that such
Depository is no longer willing or able to properly discharge its
responsibilities as Depository with respect to such Global Security, and the
Company is unable to locate a qualified successor, (b) the Company executes and
delivers to the Trustee a Company Order stating that the Company elects to
terminate the book-entry system through the Depository, (c) there shall have
occurred and be continuing an Event of Default or (d) pursuant to the following
sentence. All or any portion of a Global Security may be exchanged for a
Security that has a like aggregate principal amount and is not a Global Security
upon 20 days' prior request made by the Depository or its Agent Member to the
Securities Registrar.

      (c) If any Global Security is to be exchanged for other Securities or
cancelled in whole, it shall be surrendered by or on behalf of the Depository or
its nominee to the Securities Registrar for exchange or cancellation as provided
in this Article III. If any Global Security is to be exchanged for other
Securities or cancelled in part, or if another Security is to be exchanged in
whole or in part for a beneficial interest in any Global Security, then either
(i) such Global Security shall be so surrendered for exchange or cancellation as
provided in this Article III or (ii) the principal amount thereof shall be
reduced, subject to Section 3.6(b)(v), or increased by an amount equal to the
portion thereof to be so exchanged or cancelled, or equal to the principal
amount of such other Security to be so exchanged for a beneficial interest
therein, as the case may be, by means of an appropriate adjustment made on the
records of the Securities Registrar, whereupon the Trustee, in accordance with
the Applicable Procedures, shall instruct the Depository or its authorized
representative to make a corresponding adjustment to its records. Upon any such
surrender or adjustment of a Global Security by the Depository, accompanied by
registration instructions, the Trustee shall, subject to Section 3.5(b) and as
otherwise provided in this Article III, authenticate and deliver any Securities
issuable in exchange for such Global Security (or any portion thereof) in
accordance with the instructions of the Depository. The Trustee shall not be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be fully protected in conclusively relying on, such instructions.

      (d) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Article III, Section 9.6 or 11.6 or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global
Security, unless such Security is registered in the name of a Person other than
the Depository for such Global Security or a nominee thereof.

      (e) The Depository or its nominee, as registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under
this Indenture and the Securities, and

                                       28
<PAGE>

owners of beneficial interests in a Global Security shall hold such interests
pursuant to the Applicable Procedures. Accordingly, any such owner's beneficial
interest in a Global Security shall be shown only on, and the transfer of such
interest shall be effected only through, records maintained by the Depository or
its nominee or its Agent Members. Neither the Trustee nor the Securities
Registrar shall have any liability in respect of any transfers effected, or for
any other actions taken or not taken, by the Depository.

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

      SECTION 3.6 Registration, Transfer and Exchange Generally, Certain
Transfers and Exchanges; Securities Act Legends.

      (a) The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Securities and
of transfers of Securities. Such register is herein sometimes referred to as the
"Securities Register." The Trustee is hereby appointed "Securities Registrar"
for the purpose of registering Securities and transfers of Securities as herein
provided.

      Upon surrender for registration of transfer of any Security at the office
or agency of the Company designated for that purpose the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of the same series of any
authorized denominations, of a like aggregate principal amount, of the same
Original Issue Date and Stated Maturity and having the same terms and bearing
such restrictive legends as may be required by this Indenture.

      At the option of the Holder, Securities may be exchanged for other
Securities of the same series of any authorized denominations, of a like
aggregate principal amount, of the same Original Issue Date and Stated Maturity
and having the same terms and bearing such restrictive legends as may be
required by this Indenture, upon surrender of the Securities to be exchanged at
such office or agency. Whenever any securities are so surrendered for exchange,
the Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

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

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

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

                                       29

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

      (b) Notwithstanding any other provision of this Indenture, transfers and
exchanges of Securities and beneficial interests in a Global Security of the
kinds specified in this Section 3.6(b) shall be made only in accordance with
this Section 3.6(b).

            (i) Non-Global Security to Global Security. If the Holder of a
      Security (other than a Global Security) wishes at any time to transfer all
      or any portion of such Security to a Person who wishes to take delivery
      thereof in the form of a beneficial interest in a Global Security, such
      transfer may be effected only in accordance with the provisions of this
      Clause (b)(i) and subject to the Applicable Procedures. Upon receipt by
      the Securities Registrar of such Security as provided in Section 3.6(a)
      and instructions satisfactory to the Securities Registrar directing that a
      beneficial interest in the Global Security in a specified principal amount
      not greater than the principal amount of such Security be credited to a
      specified Agent Member's account, then the Securities Registrar shall
      cancel such Security (and issue a new Security in respect of any
      untransferred portion thereof) as provided in Section 3.6(a) and increase
      the aggregate principal amount of the Global Security by the specified
      principal amount as provided in Section 3.5(c).

            (ii) Non-Global Security to Non-Global Security. A Security that is
      not a Global Security may be transferred, in whole or in part, to a Person
      who takes delivery in the form of another Security that is not a Global
      Security as provided in Section 3.6(a).

            (iii) Exchanges Between Global Security and Non-Global Security. A
      beneficial interest in a Global Security may be exchanged for a Security
      that is not a Global Security as provided in Section 3.5.

            (iv) Intentionally Omitted.

            (v) Limitations Relating to Principal Amount. Notwithstanding any
      other provision of this Indenture and unless otherwise specified as
      permitted by Section 3.1, Securities or portions thereof may be held,
      transferred or exchanged only in principal amounts of not less than
      $100,000. Any transfer, exchange or other disposition of Securities in
      contravention of this Section 3.6(b)(v) shall be deemed to be void and of
      no legal effect whatsoever, any such transferee shall be deemed not to be
      the Holder or owner of any beneficial interest in such Securities for any
      purpose, including but not limited to the receipt of interest payable on
      such Securities, and such transferee shall be deemed to have no interest
      whatsoever in such Securities.

      The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Security (including any transfers between or among Agent Members or
beneficial owners of interests in any Global Security) other than to require
delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by the terms
of, this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

      SECTION 3.7 Mutilated, Destroyed, Lost and Stolen Securities.

      If any mutilated Security is surrendered to the Trustee together with such
security or indemnity as may be required by the Company or the Trustee to save
each of them harmless, the

                                       30
<PAGE>

Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same issue and series of like tenor and principal
amount, having the same Original Issue Date and Stated Maturity, and bearing a
number not contemporaneously outstanding.

      If there shall be delivered to the Company and to the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security, and
(ii) such security or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Company or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and upon its written request the Trustee shall authenticate and deliver, in lieu
of any such destroyed, lost or stolen Security, a new Security of the same issue
and series of like tenor and principal amount, having the same Original Issue
Date and Stated Maturity as such destroyed, lost or stolen Security, and bearing
a number not contemporaneously outstanding.

      In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

      Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

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

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

      SECTION 3.8 Payment of Interest; Interest Rights Preserved.

      Interest on any Security of any series which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date, shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such interest
in respect of Securities of such series, except that, unless otherwise provided
in the Securities of such series, interest payable on the Stated Maturity of the
principal of a Security shall be paid to the Person to whom principal is paid.
The initial payment of interest on any Security of any series which is issued
between a Regular Record Date and the related Interest Payment Date shall be
payable as provided in such Security or in the Board Resolution pursuant to
Section 3.1 with respect to the related series of Securities.

      Any interest on any Security which is payable, but is not timely paid or
duly provided for, on any Interest Payment Date for Securities of such series
(herein called "Defaulted Interest"), shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date

                                       31
<PAGE>

by virtue of having been such Holder, and such Defaulted Interest may be paid by
the Company, at its election in each case, as provided in Clause (1) or (2)
below:

            (1) The Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Securities of such series in respect of
      which interest is in default (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 Security and the date of
      the proposed payment, and at the same time the Company shall deposit with
      the Trustee an amount of money equal to the aggregate amount proposed to
      be paid in respect of such Defaulted Interest or shall make arrangements
      satisfactory to the Trustee for such deposit prior to the date of the
      proposed payment, such money when deposited to be held in trust for the
      benefit of the Persons entitled to such Defaulted Interest as in this
      Clause provided. Thereupon the Trustee shall fix a Special Record Date for
      the payment of such Defaulted Interest which shall be not more than 15
      days and not less than 10 days prior to the date of the proposed payment
      and not less than 10 days after the receipt by the Trustee of the notice
      of the proposed payment. The Trustee shall promptly notify the Company of
      such Special Record Date and, in the name and at the expense of the
      Company, shall cause notice of the proposed payment of such Defaulted
      Interest and the Special Record Date therefor to be mailed, first class,
      postage prepaid, to each Holder of a Security of such series at the
      address of such Holder as it appears in the Securities Register not less
      than 10 days prior to such Special Record Date. The Trustee may, in its
      discretion, in the name and at the expense of the Company, cause a similar
      notice to be published at least once in a newspaper, customarily published
      in the English language on each Business Day and of general circulation in
      the Borough of Manhattan, The City of New York, but such publication shall
      not be a condition precedent to the establishment of 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 the
      Securities of such series (or their respective Predecessor Securities) are
      registered on such Special Record Date and shall no longer be payable
      pursuant to the following Clause (2).

            (2) The Company may make payment of any Defaulted Interest in any
      other lawful manner not inconsistent with the requirements of any
      securities exchange on which the Securities of the series in respect of
      which interest is in default may be listed and, upon such notice as may be
      required by such exchange (or by the Trustee if the Securities are not
      listed), if, after notice given by the Company to the Trustee of the
      proposed payment pursuant to this Clause, such payment shall be deemed
      practicable by the Trustee.

      Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Security shall carry the rights to interest accrued and unpaid, and to
accrue, which were carried by such other Security.

                                       32
<PAGE>

      SECTION 3.9 Persons Deemed Owners.

      The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name any Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 3.8) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

      No holder of any beneficial interest in any Global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such Global Security, and such Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the owner of such Global
Security for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by a Depository or impair, as between a Depository and
such holders of beneficial interests, the operation of customary practices
governing the exercise of the rights of the Depository (or its nominee) as
Holder of any Security.

      SECTION 3.10 Cancellation.

      All Securities surrendered for payment, redemption, transfer or exchange
shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee, and any such Securities and Securities surrendered directly to the
Trustee for any such purpose shall be promptly canceled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly canceled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Securities shall be disposed of by the
Trustee in accordance with its customary procedures.

      SECTION 3.11 Computation of Interest.

      Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series for any
partial period shall be computed on the basis of a 360-day year of twelve 30-day
months and the actual days elapsed in a partial month in such period, and
interest on the Securities of each series for a full period shall be computed by
dividing the rate per annum by the number of interest periods that together
constitute a full twelve months.

      SECTION 3.12 Deferrals of Interest Payment Dates.

      If specified as contemplated by Section 2.1 or Section 3.1 with respect to
the Securities of a particular series, so long as no Event of Default has
occurred and is continuing, the Company shall have the right, at any time during
the term of such series, from time to time to defer the payment of interest on
such Securities for such period or periods as may be specified as contemplated
by Section 3.1 (each, an "Extension Period") during which Extension Periods the

                                       33
<PAGE>

Company shall have the right to make partial payments of interest on any
Interest Payment Date. No Extension Period shall end on a date other than an
Interest Payment Date. At the end of any such Extension Period the Company shall
pay all interest then accrued and unpaid on the Securities (together with
Additional Interest thereon, if any, at the rate specified for the Securities of
such series to the extent permitted by applicable law); provided, however, that
no Extension Period shall extend beyond the Stated Maturity of the principal of
the Securities of such series; provided, further, that during any such Extension
Period and until all accrued but unpaid interest is paid in full, the Company
shall not, and shall not permit any Subsidiary to, (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 capital stock, or (ii)
make any payment of principal of or interest or premium, if any, on or repay,
repurchase or redeem any debt security of the Company that ranks pari passu in
all respects with or junior in interest to the Securities of such series or make
any guarantee payments with respect to any guarantee by the Company of the debt
securities of any Subsidiary of the Company if such guarantee ranks pari passu
in all respects with or junior in interest to the securities of such series
(other than (a) repurchases, redemptions or other acquisitions of shares of
capital stock of the Company in connection with any employment contract, benefit
plan or other similar arrangement with or for the benefit of any one or more
employees, officers, directors or consultants, in connection with a dividend
reinvestment or shareholder stock purchase plan or in connection with the
issuance of capital stock of the Company (or securities convertible into or
exercisable for such stock) as consideration in an acquisition transaction
entered into prior to the Extension Period, (b) as a result of an exchange or
conversion of any class or series of the Company's capital stock for any other
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 the implementation or amendment of the Company shareholders'
rights plan (or any successor thereto), or the issuance of rights, stock or
other property under any such rights plan, or the redemption or repurchase of
rights pursuant thereto, or (e) any dividend in the form of stock, warrants,
options or other rights where the dividend stock or the stock issuable upon
exercise of such warrants, options or other rights is the same stock as that on
which the dividend is being paid or ranks pari passu with or junior to such
stock). Prior to the termination of any such Extension Period, the Company may
further extend the interest payment period, provided that no Extension Period
shall exceed the period or periods specified in such Securities or extend beyond
the Stated Maturity of the principal of such Securities. Upon termination of any
Extension Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due on any Interest Payment Date, the Company may elect
to begin a new Extension Period, subject to the above conditions. No interest
shall be due and payable during an Extension Period, except at the end thereof.
The Company shall give the Issuer Trustees notice of its election to begin any
such Extension Period at least one Business Day prior to the next succeeding
Interest Payment Date on which interest on Securities of such series would be
payable but for such deferral or, with respect to the Securities of a series
issued to a Citizens Trust, so long as such Securities are held by such Citizens
Trust, prior to the earlier of (i) the next succeeding date on which
Distributions on the Capital Securities of such Citizens Trust would be payable
but for such deferral or (ii) the date the Property Trustee of such Citizens
Trust is required to give notice to any securities exchange or other applicable
self-regulatory organization or to holders of such Capital Securities of the
record date or the date such

                                       34
<PAGE>

Distributions are payable, but in any event not less than one Business Day prior
to such record date. For purposes hereof, the Company's Senior Indebtedness
shall not be deemed to be pari passu with the Securities.

      The Trustee, at the expense of the Company, shall promptly give notice of
the Company's election to begin any such Extension Period to the Holders of the
Outstanding Securities of such series.

      SECTION 3.13 Right of Set-Off.

      With respect to the Securities of a series issued to a Citizens Trust,
notwithstanding anything to the contrary herein, the Company shall have the
right to set-off any payment it is otherwise required to make thereunder in
respect of any such Security to the extent the Company has theretofore made, or
is concurrently on the date of such payment making, a payment under the Citizens
Guarantee relating to such Security or under Section 5.8 hereof.

      SECTION 3.14 Agreed Tax Treatment.

      Each Security issued hereunder shall provide that the Company and, by its
acceptance of a Security or a beneficial interest therein, the Holder of, and
any Person that acquires a beneficial interest in, such Security agree that for
United States federal, state and local tax purposes it is intended that such
Security constitutes indebtedness.

      SECTION 3.15 CUSIP Numbers.

      The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption or other related material as a convenience to Holders; provided
that any such notice or other related material may state that no representation
is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice of redemption or other related material
and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption shall not be affected by any defect
in or omission of such numbers. The Company shall promptly notify the Trustee
of any change in the CUSIP number(s).

                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

      SECTION 4.1 Satisfaction and Discharge of Indenture.

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

     (1)         either

          (A)    all Securities theretofore authenticated and delivered (other
  than (i) Securities which have been destroyed, lost or stolen and which have
  been replaced or paid as provided in Section 3.7 and (ii) Securities for whose
  payment money has theretofore been deposited in trust or segregated and held
  in trust by the Company and thereafter repaid to the Company or discharged
  from such trust, as provided in Section 10.3) have been delivered to the
  Trustee for cancellation; or

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

               (i)      have become due and payable, or

               (ii)     will become due and payable at their Stated Maturity
     within one year of the date of deposit, or

               (iii)    are to be called for redemption within one year by the
     Trustee in the name, and at the expense, of the Company,

     and the Company, in the case of Clause (B) (i), (ii) or (iii) above, has
deposited or caused to be deposited with the Trustee as trust funds in trust for
such purpose an amount in cash, direct obligations of the United States of
America backed by its full faith and credit ("U.S. Government Obligations"), or
a combination thereof in each case sufficient to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for
cancellation, for principal (and premium, if any) and interest (including any
Additional Interest) to the date of such deposit (in the case of Securities
which have become due and payable) or to the Stated Maturity or Redemption Date,
as the case may be;

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

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

                                       35
<PAGE>

     Notwithstanding the satisfaction and discharge of this Indenture, or the
earlier resignation or removal of the Trustee or any Authenticating Agent, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Company to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to Subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 4.5 and the last
paragraph of Section 10.3 shall survive.

     SECTION 4.2 Defeasance and Discharge.

     The following provisions shall apply to the Securities of each series
unless specifically otherwise provided in a Board Resolution, Officers'
Certificate or indenture supplemental hereto provided pursuant to Section 3.1.
In addition to discharge of this Indenture pursuant to Sections 4.1 and 4.3, the
Company shall be deemed to have paid and discharged the entire indebtedness on
all the Securities of such a series as provided in this Section on and after the
date the conditions set forth in Section 4.4 are satisfied, and the provisions
of this Indenture with respect to the Securities of such series shall no longer
be in effect (except as to (i) rights of registration of transfer and exchange
of Securities of such series, (ii) substitution of mutilated, defaced,
destroyed, lost or stolen Securities of such series, (iii) rights of Holders of
Securities of such series to receive, solely from the trust fund described in

expenses of any Citizens Trust under Section 6.7) (hereinafter called
"Defeasance"), and the Trustee at the cost and expense of the Company, shall
execute proper instruments acknowledging the same.

     SECTION 4.3 Covenant Defeasance.

     (i) The Company shall be released from its obligations under any covenants
specified in or pursuant to this Indenture (except as to (A) rights of
registration of transfer and exchange of Securities of such series, (B)
substitution of mutilated, defaced, destroyed, lost or stolen Securities of such
series, (C) rights of Holders of Securities of such series to receive, from the

result in an Event of Default or Debenture Default, in each case with respect to
the Outstanding Securities of such series as provided in this Section on and
after the date the conditions set forth in Section 4.4 are satisfied
(hereinafter called "Covenant Defeasance"), and the Trustee, at the cost and
expense of the Company, shall execute proper instruments acknowledging the same.
For this purpose, such Covenant Defeasance means that the Company may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly by
reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any other
document, but the remainder of this Indenture and the Securities of such series
shall be unaffected thereby.

<PAGE>

     SECTION 4.4 Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to application of either Section 4.2
or 4.3 to the Outstanding Securities:

     (1)  with reference to Section 4.2 or 4.3, the Company has irrevocably
deposited or caused to be irrevocably deposited with the Trustee as funds in
trust, specifically pledged as security for, and dedicated solely to, the
benefit of the Holders of Securities of such series (i) cash in an amount, or
(ii) U.S. Government Obligations, maturing as to principal and interest, if any,
at such times and in such amounts as will insure the availability of cash, or
(iii) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge (A)
the principal of and interest, if any, on all Securities of such series on each
date that such principal or interest, if any, is due and payable, and (B) any
mandatory sinking fund payments on the dates on which such payments are due and
payable in accordance with the terms of this Indenture and the Securities of
such series;

     (2)  in the case of Defeasance under Section 4.2, the Company has delivered
to the Trustee an Opinion of Counsel based on the fact that (x) the Company has
received from the Internal Revenue Service a ruling or (y), since the date
hereof, there has been a change in the applicable United States federal income
tax law, in either case to the effect that, and such opinion shall confirm that,
the Holders of the Securities of such series will not recognize income, gain or
loss for United States federal income tax purposes as a result of such deposit,
Defeasance and discharge and will be subject to United States federal income tax
on the same amount and in the same manner and at the same times, as would have
been the case if such deposit, Defeasance and discharge had not occurred;

     (3)  in the case of Covenant Defeasance under Section 4.3, the Company has
delivered to the Trustee an Opinion of Counsel to the effect that, and such
opinion shall confirm that, the Holders of the Securities of such series will
not recognize income, gain or loss for United States federal income tax purposes
as a result of such deposit and Covenant Defeasance and will be subject to
United States federal income tax on the same amount and in the same manner and
at the same times, as would have been the case if such deposit and Covenant
Defeasance had not occurred;

     (4)  the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent contemplated by this provision have been complied with.

     SECTION 4.5 Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 10.3, all money
and U.S. Government Obligations deposited with the Trustee pursuant to Section
4.4 shall be held in trust, and such money and all money from such U.S.
Government Obligations shall be applied by it, in accordance with the provisions
of the Securities and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest for whose payment such money and U.S. Government
Obligations has been deposited with the Trustee.

     SECTION 4.6 Indemnity for U.S. Government Obligations.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 4.4 or the principal or interest received in
respect of such obligations other than any such tax, fee or other charge that by
law is for the account of the Holders of Outstanding Securities.

     SECTION 4.7 Reinstatement.

     If the Trustee is unable to apply any money or Government Obligations in
accordance with Section 4.4 by reason of any legal preceding or by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to Section 4.4, until such time as the Trustee or
Paying Agent is permitted to apply all such money or Government Obligations in
accordance with Section 4.4; provided that, if the Company has made any payment
of principal or interest on the Securities of any series because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or
Government Obligations held by the Trustee or Paying Agent.

                                    REMEDIES

      SECTION 5.1 Events of Default.

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

            (1) default in the payment of any interest upon any Security of that
      series, including any Additional Interest in respect thereof, when it
      becomes due and payable, and continuance of such default for a period of
      30 days (subject to the deferral of any due date in the case of an
      Extension Period); or

            (2) default in the payment of the principal of (or premium, if any,
      on) any Security of that series at its Maturity; or

            (3) default in the performance, or breach, in any material respect,
      of any covenant of the Company in this Indenture (other than a covenant a
      default in the performance of which or the breach of which 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 at least 25% in principal amount of the
      Outstanding Securities of that series a written notice specifying such
      default or breach and requiring it to be remedied; or

            (4) the entry of a decree or order for relief in respect of the
      Company by a court having jurisdiction in the premises in an involuntary
      case under Federal or State bankruptcy laws, as now or hereafter
      constituted, and the continuance of any such decree or order unstayed and
      in effect for a period of 60 consecutive days; or

            (5) the commencement by the Company of a voluntary case under
      Federal or State bankruptcy laws, as now or hereafter constituted, or the
      consent by the Company to the entry of a decree or order for relief in an
      involuntary case under any such laws; or

            (6) any other Event of Default provided with respect to Securities
      of that series.

      SECTION 5.2 Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default (other than an Event of Default specified in
Section 5.1(4) or 5.1(5)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in aggregate principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
the Securities of that series are Discount Securities, such portion of the
principal amount as

                                       38
<PAGE>

may be specified in the terms of that series) of all the Securities of that
series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), provided that, in the case of the
Securities of a series issued to a Citizens Trust, if, upon an Event of Default,
the Trustee or the Holders of not less than 25% in aggregate principal amount of
the Outstanding Securities of that series fail to declare the principal of all
the Securities of that series to be immediately due and payable, the holders of
at least 25% in aggregate Liquidation Amount (as defined in the related Trust
Agreement) of the corresponding series of Capital Securities then Outstanding
shall have such right by a notice in writing to the Company and the Trustee; and
upon any such declaration such principal amount (or specified portion thereof)
of and the accrued interest (including any Additional Interest) on all the
Securities of such series shall become immediately due and payable. Payment of
principal and interest (including any Additional Interest) on such Securities
shall remain subordinated to the extent provided in Article XIII notwithstanding
that such amount shall become immediately due and payable as herein provided. If
an Event of Default specified in Section 5.1(4) or 5.1(5) with respect to
Securities of any series at the time Outstanding occurs, the principal amount of
all the Securities of that series (or, if the Securities of that series are
Discount Securities, such portion of the principal amount of such Securities as
may be specified by the terms of that series) shall automatically, and without
any declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable.

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

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

                  (A) all overdue installments of interest (including any
            Additional Interest) on all Securities of that series,

                  (B) the principal of (and premium, if any, on) any Securities
            of that series which have become due otherwise than by such
            declaration of acceleration and interest thereon at the rate borne
            by the Securities, and

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

            (2) all Events of Default with respect to Securities of that series,
      other than the non-payment of the principal of Securities of that series
      which has become due solely by such acceleration, have been cured or
      waived as provided in Section 5.13.

      In the case of Securities of a series issued to a Citizens Trust, the
holders of a majority in aggregate Liquidation Amount (as defined in the Trust
Agreement under which such Citizens Trust is formed) of the related series of
Capital Securities issued by such Citizens Trust shall also

                                       39
<PAGE>

have the right to rescind and annul such declaration and its consequences by
written notice to the Company and the Trustee, subject to the satisfaction of
the conditions set forth in Clauses (1) and (2) above of this Section 5.2.

      No such rescission shall affect any subsequent default or impair any right
consequent thereon.

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

      The Company covenants that if:

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

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

the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal, including any sinking fund payment or
analogous obligations (and premium, if any) and interest (including any
Additional Interest); and, in addition thereto, all amounts owing the Trustee
under Section 6.7.

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

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

      SECTION 5.4 Trustee May File Proofs of Claim.

      In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors,

      (a) the Trustee (irrespective of whether the principal of the Securities
of any series shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have made
any demand on the Company for the payment of overdue

                                       40
<PAGE>

principal (and premium, if any) or interest (including any Additional Interest))
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

            (i) to file and prove a claim for the whole amount of principal (and
      premium, if any) and interest (including any Additional Interest) owing
      and unpaid in respect to the Securities and to file such other papers or
      documents as may be necessary or advisable and to take any and all actions
      as are authorized under the Trust Indenture Act in order to have the
      claims of the Holders and any predecessor to the Trustee under Section 6.7
      allowed in any such judicial proceedings; and

            (ii) in particular, the Trustee shall be authorized to collect and
      receive any monies or other property payable or deliverable on any such
      claims and to distribute the same in accordance with Section 5.6; and

      (b) any custodian, receiver, assignee, trustee, liquidator, sequestrator
(or other similar official) in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee for distribution in
accordance with Section 5.6, and in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any
amount due to it and any predecessor Trustee under Section 6.7.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

      SECTION 5.5 Trustee May Enforce Claim Without Possession of Securities.

      All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of all the amounts owing the Trustee and any predecessor Trustee
under Section 6.7, its agents and counsel, be for the ratable benefit of the
Holders of the Securities in respect of which such judgment has been recovered.

      SECTION 5.6 Application of Money Collected.

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

      FIRST: To the payment of all amounts due the Trustee and any predecessor
Trustee;

                                       41
<PAGE>

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

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

      SECTION 5.7 Limitation on Suits.

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

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

            (2) the Holders of not less than 25% in aggregate principal amount
      of the Outstanding Securities of that series shall have made written
      request to the Trustee to institute proceedings in respect of such
      Debenture Default in its own name as Trustee hereunder;

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing itself of, any
provision of this Indenture to affect, disturb or prejudice the rights of any
other Holders of Securities, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders (it being understood that the Trustee does not have
an affirmative duty to ascertain whether or not such actions or forbearances are
unduly prejudicial to such Holders).

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

      Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 3.8)
interest (including any Additional Interest) on such Security on the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on
the Redemption Date) and to institute suit for the enforcement of any such

                                       42
<PAGE>

payment, and such right shall not be impaired without the consent of such
Holder. In the case of Securities of a series issued to a Citizens Trust, any
holder of the corresponding series of Capital Securities issued by such Citizens
Trust shall have the right, upon the occurrence of an Debenture Default
described in Section 5.1(1) or 5.1(2), to institute a suit directly against the
Company for enforcement of payment to such holder of principal of (premium, if
any) and (subject to Section 3.8) interest (including any Additional Interest)
on the Securities having a principal amount equal to the aggregate Liquidation
Amount (as defined in the Trust Agreement under which such Citizens Trust is
formed) of such Capital Securities of the corresponding series held by such
holder.

      SECTION 5.9 Restoration of Rights and Remedies.

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

      SECTION 5.10 Rights and Remedies Cumulative.

      Except as otherwise provided in the last paragraph of Section 3.7, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

      SECTION 5.11 Delay or Omission Not Waiver.

      No delay or omission of the Trustee, any Holder of any Security or any
holder of any Capital Security to exercise any right or remedy accruing upon any
Debenture Default shall impair any such right or remedy or constitute a waiver
of any such Debenture Default or an acquiescence therein.

      Every right and remedy given by this Article or by law to the Trustee or
to the Holders and the right and remedy given to the holders of Capital
Securities by Section 5.8 may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee, the Holders or the holders of Capital
Securities, as the case may be.

      SECTION 5.12 Control by Holders.

      The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any

                                       43
<PAGE>

remedy available to the Trustee or exercising any trust or power conferred on
the Trustee, with respect to the Securities of such series, provided that:

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

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

            (3) subject to the provisions of Section 6.1, the Trustee shall have
      the right to decline to follow such direction if a Responsible Officer or
      Officers of the Trustee shall, in good faith, determine that the
      proceeding so directed would be unjustly prejudicial to the Holders not
      joining in any such direction or would involve the Trustee in personal
      liability.

      SECTION 5.13 Waiver of Past Defaults.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series and, in the case of any Securities of a
series issued to a Citizens Trust, the holders of Capital Securities issued by
such Citizens Trust may waive any past default hereunder and its consequences
with respect to such series except a default:

            (1) in the payment of the principal of (or premium, if any) or
      interest (including any Additional Interest) on any Security of such
      series, or

            (2) in respect of a covenant or provision hereof which under Article
      IX cannot be modified or amended without the consent of the Holder of each
      Outstanding Security of such series affected.

      Any such waiver shall be deemed to be on behalf of the Holders of all the
Securities of such series or, in the case of a waiver by holders of Capital
Securities issued by such Citizens Trust, by all holders of Capital Securities
issued by such Citizens Trust.

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

      SECTION 5.14 Undertaking for Costs.

      All parties to this Indenture agree, and each Holder of any Security by
his 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

                                       44
<PAGE>

any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of the Outstanding Securities of any series,
or to any suit instituted by any Holder for the enforcement of the payment of
the principal of (or premium, if any) or interest (including any Additional
Interest) on any Security on or after the respective Stated Maturities expressed
in such Security.

      SECTION 5.15 Waiver of Usury, Stay or Extension Laws.

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

                                   ARTICLE VI

                                   THE TRUSTEE

      SECTION 6.1 Certain Duties and Responsibilities.

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

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

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture; but
      in the case of any such certificates or opinions which by any provisions
      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 to the requirements of this Indenture (but need not
      confirm or investigate the accuracy of mathematical calculations or other
      facts stated therein).

      (b) In case an Event of Default has occurred and is continuing, 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
his own affairs.

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

            (1) this Subsection shall not be construed to limit the effect of
      Subsection (a) of this Section;

                                       45
<PAGE>

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

            (3) 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 Holders pursuant to Section 5.12 relating to the time, method
      and place of conducting any proceeding for any remedy available to the
      Trustee, or exercising any trust or power conferred upon the Trustee,
      under this Indenture with respect to the Securities of such series.

      (d) No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder, or in the exercise of any of its rights or
powers, if there shall be reasonable grounds for believing that repayment of
such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

      (e) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

      SECTION 6.2 Notice of Defaults.

      Within 90 days after actual knowledge by a Responsible Officer of the
Trustee of the occurrence of any default hereunder with respect to the
Securities of any series, the Trustee shall transmit by mail to all Holders of
Securities of such series, as their names and addresses appear in the Securities

waived; provided, however, that, except in the case of a default in the payment
of the principal of (or premium, if any) or interest (including any Additional
Interest) on any Security of such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders of Securities of such series; and provided, further,
that, in the case of any default of the character specified in Section 5.1(3),
no such notice to Holders of Securities of such series shall be given until at
least 30 days after the occurrence thereof. For the purpose of this Section, the
term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default with respect to Securities of such
series.

      attributable to its negligence or bad faith; and

            (3) to indemnify each of the Trustee or any predecessor Trustee and

                                       48
<PAGE>

      When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under the Bankruptcy Reform Act of 1978 or any successor statute.

      SECTION 6.8 Disqualification; Conflicting Interests.

      The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act as a
matter of contract. Nothing herein shall prevent the Trustee from filing with
the Commission the application referred to in the second to last paragraph of
said Section 310(b).

      SECTION 6.9 Corporate Trustee Required; Eligibility.

      There shall at all times be a Trustee hereunder which shall be

      (a) a corporation organized and doing business under the laws of the
United States of America or of any State or Territory or the District of
Columbia, authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by federal, state, territorial or District
of Columbia authority, or

      (b) a corporation or other Person organized and doing business under the
laws of a foreign government that is permitted to act as Trustee pursuant to a

substantially equivalent to supervision or examination applicable to United
States institutional trustees,

in either case having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority. If such
corporation 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 shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article. Neither the Company nor any Person directly or indirectly
controlling, controlled by or under common control with the Company shall serve
as Trustee for the Securities of any series issued hereunder.

      SECTION 6.10 Resignation and Removal; Appointment of Successor.

      (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

      (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of

                                       49
<PAGE>
such notice of resignation, the resigning Trustee may, at the expense of the
Company, petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

      (c) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

      (d) If at any time:

            (1) the Trustee shall fail to comply with Section 6.8 after written
      request therefor by the Company or by any Holder who has been a bona fide
      Holder of a Security for at least six months, or

            (2) the Trustee shall cease to be eligible under Section 6.9 and
      shall fail to resign after written request therefor by the Company or by
      any such Holder, or

            (3) the Trustee shall become incapable of acting or shall be
      adjudged a 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, (i) the Company, acting pursuant to the authority of a
Board Resolution, may remove the Trustee with respect to all Securities, or (ii)
subject to Section 5.14, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.

      (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee with respect to the Securities of
that or those series. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee with respect to the Securities of such series and supersede
the successor Trustee appointed by the Company. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Security for at least
six months may, subject to Section 5.14, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

      (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Securities of such series as their names and addresses

                                       50
<PAGE>

appear in the Securities Register. Each notice shall include the name of the
successor Trustee with respect to the Securities of such series and the address
of its Corporate Trust Office.

      SECTION 6.11 Acceptance of Appointment by Successor.

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

      (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an instrument in writing or an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such instrument in writing or supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such instrument in writing or supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts, and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

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

                                       51
<PAGE>

      (d) No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be eligible under this Article.

      SECTION 6.12 Merger, Conversion, Consolidation or Succession to Business.

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

      SECTION 6.13 Preferential Collection of Claims Against Company.

      If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

      SECTION 6.14 Appointment of Authenticating Agent.

      The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue
and upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 3.7, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, or of any State or Territory or
the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                                       52
<PAGE>

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

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provision of this Section.

      The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

      If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

      This is one of the Securities referred to in the within mentioned
Indenture.

      (c) Every Holder of Securities, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of the
disclosure of information as to the names and addresses of the Holders made
pursuant to the Trust Indenture Act.

      SECTION 7.3 Reports by Trustee.

transmit to Holders, such information, documents and other reports, and such

such information, documents or reports required to be filed with the Commission

      Default, and no event which, after notice or lapse of time, or both, would
      become an Event of Default, shall have happened and be continuing;

            (3) in the case of the Securities of a series issued to a Citizens
      Trust, such consolidation, merger, conveyance, transfer or lease is
      permitted under the related Trust

                                       55
<PAGE>

      Agreement and Citizens Guarantee and does not give rise to any breach or
      violation of the related Trust Agreement or Citizens Guarantee; and

            (4) the Company has delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that such
      consolidation, merger, conveyance, transfer or lease and any such
      supplemental indenture comply with this Article and that all conditions
      precedent herein provided for relating to such transaction have been
      complied with; and the Trustee, subject to Section 6.1, may rely upon such
      Officers' Certificate and Opinion of Counsel as conclusive evidence that
      such transaction complies with this Section 8.1.

      SECTION 8.2 Successor Corporation Substituted.

      Upon any consolidation or merger by the Company with or into any other
Person, or any conveyance, transfer or lease by the Company of its properties
and assets substantially as an entirety to any Person in accordance with Section
8.1, the successor corporation formed by such consolidation or into which the
Company is merged or to which such conveyance, transfer or lease is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under this Indenture with the same effect as if such successor
Person had been named as the Company herein; and in the event of any such
conveyance, transfer or lease the Company shall be discharged from all
obligations and covenants under the Indenture and the Securities and may be
dissolved and liquidated.

      Such successor Person 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 Securities issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee; and, upon the order of such successor Person instead
of the Company and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication pursuant to such provisions and
any Securities which such successor Person thereafter shall cause to be signed
and delivered to the Trustee on its behalf for the purpose pursuant to such
provisions. All the Securities so issued shall in all respects have the same
legal rank and benefit under this Indenture as the Securities theretofore or
thereafter issued in accordance with the terms of this Indenture as though all
of such Securities had been issued at the date of the execution hereof.

      In case of any such consolidation, merger, sale, conveyance or lease, such
changes in phraseology and form may be made in the Securities thereafter to be
issued as may be appropriate.

Board Resolution, and the Trustee, at any time and from time to time, may enter
into one or more

the following purposes:

            (1) to evidence the succession of another Person to the Company, and
      the assumption by any such successor of the covenants of the Company
      herein and in the Securities contained; or

            (2) to convey, transfer, assign, mortgage or pledge any property to
      or with the Trustee or to surrender any right or power herein conferred

      Holders of all or any series of Securities (and if such covenants are to
      be for the benefit of less than all series of Securities, stating that
      such covenants are expressly being included solely for the benefit of such
      series) or to surrender any right or power herein conferred upon the
      Company; or

            (5) to add any additional Events of Default for the benefit of the
      Holders of all or any series of Securities (and if such additional Events
      of Default are to be for the benefit of less than all series of
      Securities, stating that such additional Events of Default are expressly
      being included solely for the benefit of such series); or

            (6) to change or eliminate any of the provisions of this Indenture,
      provided that any such change or elimination (a) shall become effective
      only when there is no Security Outstanding of any series created prior to
      the execution of such supplemental indenture which is entitled to the
      benefit of such provision or (b) shall not apply to any Outstanding
      Securities; or

            (7) to cure any ambiguity, to correct or supplement any provision
      herein which may be defective or inconsistent with any other provision
      herein, or to make any other provisions with respect to matters or
      questions arising under this Indenture; provided that such action pursuant
      to this Clause (7) shall not adversely affect the interest of the Holders
      of Securities of any series in any material respect or, in the case of the
      Securities of a series issued to a Citizens Trust and for so long as any
      of the corresponding series of Capital Securities issued by such Citizens
      Trust shall remain outstanding, the holders of such Capital Securities; or

            (8) to evidence and provide for the acceptance of appointment
      hereunder by a successor Trustee with respect to the Securities of one or
      more series 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 6.11(b); or

            (9) to comply with the requirements of the Commission in order to

      SECTION 9.2 Supplemental Indentures with Consent of Holders.

      With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

            (1) except to the extent permitted by Section 3.12 or as otherwise
      specified as contemplated by Section 2.1 or Section 3.1 with respect to
      the deferral of the payment of interest on the Securities of any series,
      change the Stated Maturity of the principal of, or any installment of
      interest (including any Additional Interest) on, any Security, or reduce
      the principal amount thereof or the rate of interest thereon or reduce any
      premium payable upon the redemption thereof, or reduce the amount of
      principal of a Discount Security that would be due and payable upon a
      declaration of acceleration of the Maturity thereof pursuant to Section
      5.2, or change the place of payment where, or the coin or currency in
      which, any Security or interest thereon is payable, or impair the right to
      institute suit for the enforcement of any such payment on or after the
      Stated Maturity thereof (or, in the case of redemption, on or after the
      Redemption Date), or

            (2) reduce the percentage in principal amount of the Outstanding
      Securities of any series, the consent of whose Holders is required for any
      such supplemental indenture, or the consent of whose Holders is required
      for any waiver (of compliance with certain provisions of this Indenture or
      certain defaults hereunder and their consequences) provided for in this
      Indenture, or

            (3) modify any of the provisions of this Section, Section 5.13 or
      Section 10.5, except to increase any such percentage or to provide that
      certain other provisions of this Indenture cannot be modified or waived

provided, further, that, in the case of the Securities of a series issued to a
Citizens Trust, so long as any of the corresponding series of Capital Securities
issued by such Citizens Trust remains outstanding, (i) no such amendment shall
be made that adversely affects the holders of such Capital Securities in any
material respect, and no termination of this Indenture shall occur, and no
waiver of any Event of Default or compliance with any covenant under this
Indenture shall be effective, without the prior consent of the holders of at
least a majority of the aggregate Liquidation Amount of such Capital Securities
then outstanding unless and until the principal (and premium, if any) of the
Securities of such series and all accrued and, subject to Section 3.8, unpaid
interest (including any Additional Interest) thereon have been paid in full and
(ii) no amendment shall be made to Section 5.8 of this Indenture that would
impair the rights of the holders of Capital Securities provided therein without
the prior consent of the holders of each Capital Security then outstanding
unless and until the principal (and premium, if any) of the

                                       58
<PAGE>

Securities of such series and all accrued and (subject to Section 3.8) unpaid
interest (including any Additional Interest) thereon have been paid in full.

      A supplemental indenture that changes or eliminates any covenant or other
provision of this Indenture that has expressly been included solely for the
benefit of one or more particular series of Securities or Capital Securities, or
which modifies the rights of the Holders of Securities or holders of Capital
Securities of such series with respect to such covenant or other provision,
shall be deemed not to affect the rights under this Indenture of the Holders of
Securities or holders of Capital Securities of any other series.

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

      SECTION 9.3 Execution of Supplemental Indentures.

      In executing or accepting the additional trusts created by any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall receive, and (subject to
Section 6.1) shall be fully protected in conclusively relying upon, an Officers'
Certificate and an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture, and that
all conditions precedent have been complied with. The Trustee may, but shall not
be obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise or
that may subject it to any liability.

      SECTION 9.4 Effect of Supplemental Indentures.

      Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

      SECTION 9.5 Conformity with Trust Indenture Act.

      Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

      SECTION 9.6 Reference in Securities to Supplemental Indentures.

      Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Company, bear a notation in form approved by the Company as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Company, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities of such series.

                                   COVENANTS

      SECTION 10.1 Payment of Principal, Premium and Interest.

      The Company covenants and agrees for the benefit of each series of
securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of such Securities and this Indenture.

      SECTION 10.2 Maintenance of Office or Agency.

      The Company will maintain in each Place of Payment for any series of
Securities, an office or agency where Securities of that series may be presented
or surrendered for payment and an office or agency where Securities of that
series may be surrendered for transfer or exchange and where notices and demands
to or upon the Company in respect of the Securities of that series and this
Indenture may be served. The Company initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes. The Company
will give prompt written notice to the Trustee of any change in the location of
any such office or agency. If at any time the Company shall fail to maintain
such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

      The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
of such purposes, and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in each Place of
Payment for Securities of any series for such purposes. The Company will give
prompt written notice to the Trustee of any such designation and any change in
the location of any such office or agency.

      SECTION 10.3 Money for Security Payments to be Held in Trust.

      If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of such
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and will promptly notify the Trustee of its
failure so to act.

      Whenever the Company shall have one or more Paying Agents, it will, prior
to 10:00 a.m. New York City time on each due date of the principal of or
interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due, such sum to be
held in trust for the benefit of the Persons entitled to such principal and
premium (if any) or interest, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its failure so to act.

                                       60
<PAGE>

      The Company will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying
Agent will:

            (1) hold all sums held by it for the payment of the principal of
      (and premium, if any) or interest on Securities in trust for the benefit
      of the Persons entitled thereto until such sums shall be paid to such
      Persons or otherwise disposed of as herein provided;

            (2) give the Trustee notice of any default by the Company (or any
      other obligor upon the Securities) in the making of any payment of
      principal (and premium, if any) or interest;

            (3) at any time during the continuance of any such default, upon the
      written request of the Trustee, forthwith pay to the Trustee all sums so
      held in trust by such Paying Agent; and

            (4) comply with the provisions of the Trust Indenture Act applicable
      to it as a Paying Agent.

      The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest on any Security and remaining unclaimed for two years after such
principal (and premium, if any) or interest has become due and payable shall be
paid on Company Request to the Company, or (if then held by the Company) shall
(unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease.

      SECTION 10.4 Statement as to Compliance; Statement by Officers as to
Default.

      The Company shall deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate executed by the

                                       61
<PAGE>

principal executive officer, principal financial officer or principal accounting
officer of the Company covering the preceding calendar year, stating whether or
not to the best knowledge of the signers thereof the Company is in default in
the performance, observance or fulfillment of or compliance with any of the
terms, provisions, covenants and conditions of this Indenture, and if the
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge. For the purpose of this Section
10.4, compliance shall be determined without regard to any grace period (other
than an Extension Period) or requirement of notice provided pursuant to the
terms of this Indenture.

      The Company shall deliver to the Trustee, as soon as possible and in any
event within five days after the Company becomes aware of the occurrence of any
Event of Default or an event which, with notice or the lapse of time or both,
would constitute an Event of Default, an Officers' Certificate setting forth the
details of such Event of Default or default and the action which the Company
proposes to take with respect thereto.

      SECTION 10.5 Waiver of Certain Covenants.

      The Company may omit in any particular instance to comply with any
covenant or condition provided pursuant to Section 3.1, 9.1(3) or 9.1(4) with
respect to the Securities of any series, if before or after the time for such
compliance the Holders of at least a majority in principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company in respect of any
such covenant or condition shall remain in full force and effect.

      SECTION 10.6 Additional Sums.

      In the case of the Securities of a series issued to a Citizens Trust, so
long as no Event of Default has occurred and is continuing and except as
otherwise specified as contemplated by Section 2.1 or Section 3.1, in the event
that (i) a Citizens Trust is the Holder of all of the Outstanding Securities of
such series and (ii) a Tax Event in respect of such Citizens Trust shall have
occurred and be continuing, the Company shall pay to such Citizens Trust (and
its permitted successors or assigns under the related Trust Agreement) as Holder
of the Securities of such series for so long as such Citizens Trust (or its
permitted successor or assignee) is the registered Holder of any Securities of
such series, such additional sums as may be necessary in order that the amount
of Distributions (including any Additional Amounts (as defined in such Trust
Agreement)) paid by such Citizens Trust on the related Capital Securities and
Common Securities that at any time remain outstanding in accordance with the
terms thereof shall not be reduced as a result of any Additional Taxes (the
"Additional Sums"). Whenever in this Indenture or the Securities there is a
reference in any context to the payment of principal of or interest on the
Securities, such mention shall be deemed to include mention of the payments of
the Additional Sums provided for in this paragraph to the extent that, in such
context, Additional Sums are, were or would be payable in respect thereof
pursuant to the provisions of this paragraph and express mention of the payment
of Additional Sums (if applicable) in any provisions hereof shall not be
construed as excluding Additional Sums in those provisions hereof where such
express mention is not made; provided, however, that the deferral of the payment
of interest pursuant to Section 3.12 or the Securities shall not defer the
payment of any Additional Sums that may be due and payable.

                                       62
<PAGE>

      SECTION 10.7 Additional Covenants.

      The Company covenants and agrees with each Holder of Securities of each
series that it shall not, and it shall not permit any Subsidiary of the Company
to, (a) declare or pay any dividends or distributions on, or redeem, purchase,
acquire or make a liquidation payment with respect to, any shares of the
Company's capital stock, or (b) make any payment of principal of or interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank pari passu in all respects with or junior in interest to the
Securities of such series or make any guarantee payments with respect to any
guarantee by the Company of debt securities of any Subsidiary of the Company if
such guarantee ranks pari passu with or junior in interest to the Securities
(other than (a) repurchases, redemptions or other acquisitions of shares of
capital stock of the Company in connection with any employment contract, benefit
plan or other similar arrangement with or for the benefit of any one or more
employees, officers, directors or consultants, in connection with a dividend
reinvestment or shareholder stock purchase plan or in connection with the
issuance of capital stock of the Company (or securities convertible into or
exercisable for such stock) as consideration in an acquisition transaction
entered into prior to the Extension Period; (b) as a result of an exchange or
conversion of any class or series of the Company's capital stock for any other
class or series of the Company's capital stock or 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 the implementation or amendment of the Company shareholders'
rights plan (or any successor thereto), or the issuance of rights, stock or
other property under any such rights plan, or the redemption or repurchase of
rights pursuant hereto; or (e) any dividend in the form of stock, warrants,
options or other rights where the dividend stock or the stock issuable upon
exercise of such warrants, options or other rights is the same stock as that on
which the dividend is being paid or ranks pari passu with or junior to such
stock) if at such time (i) there shall have occurred any event of which the
Company has actual knowledge that (A) with the giving of notice or the lapse of
time or both, would constitute an Event of Default with respect to the
Securities of such series and (B) in respect of which the Company shall not have
taken reasonable steps to cure, (ii) if the Securities of such series are held
by a Citizens Trust, the Company shall be in default with respect to its payment
of any obligations under the Citizens Guarantee relating to the Capital
Securities issued by such Citizens Trust or (iii) the Company shall have given
notice of its election to begin an Extension Period with respect to the
Securities of such series as provided herein and shall not have rescinded such
notice, or such Extension Period, or any extension thereof, shall be continuing.
For purposes hereof, the Company's Senior Indebtedness shall not be deemed to be
pari passu with the Securities.

      The Company also covenants with each Holder of Securities of a series
issued to a Citizens Trust (i) to maintain directly or indirectly 100% ownership
of the Common Securities of such Citizens Trust; provided, however, that any
permitted successor of the Company hereunder may succeed to the Company's
ownership of such Common Securities; (ii) as holder of the Common Securities,
not to voluntarily terminate, wind-up or liquidate such Citizens Trust, except
upon prior approval of the Federal Reserve, if then required under applicable
capital guidelines or policies of the Federal Reserve, and (a) in connection
with a distribution of the Securities of such series to the holders of Capital
Securities in liquidation of such Citizens Trust

                                       63
<PAGE>

or (b) in connection with certain mergers, consolidations or amalgamations
permitted by the related Trust Agreement; and (iii) to use its reasonable
efforts, consistent with the terms and provisions of such Trust Agreement, to
cause such Citizens Trust to remain classified as not an association taxable as
a corporation for United States Federal income tax purposes.

      SECTION 10.8 Original Issue Discount.

      On or before December 15 of each year during which any Securities are
outstanding, the Company shall furnish to each Paying Agent such information as
may be necessary in order that each Paying Agent may prepare the information
which it is required to report for such year on Internal Revenue Service Forms
1096 and 1099 pursuant to Section 6049 of the Internal Revenue Code of 1986, as
amended. Such information shall include the amount of original issue discount
includible in income for each $1,000 of principal amount at Stated Maturity of
outstanding Securities during such year.

                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

      SECTION 11.1 Applicability of This Article.

      Redemption of Securities of any series (whether by operation of a sinking
fund or otherwise) as permitted or required by any form of Security issued
pursuant to this Indenture shall be made in accordance with such form of
Security and this Article; provided, however, that if any provision of any such
form of Security shall conflict with any provision of this Article, the
provision of such form of Security shall govern. Except as otherwise set forth
in the form of Security for such series, each Security of such series shall be
subject to partial redemption only in the amount of $1,000 or integral multiples
thereof and the principal amount of the unredeemed portion of such Security is
not less than $100,000.

      SECTION 11.2 Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
or pursuant to a Board Resolution. In case of any redemption at the election of
the Company of any of the Securities of any particular series and having the
same terms, the Company shall, not less than 45 nor more than 60 days prior to
the Redemption Date (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee and, in the case of Securities of a series held by
a Citizens Trust, the related Property Trustee of such date and of the principal
amount of Securities of that series to be redeemed and provide the additional
information required to be included in the notice or notices contemplated by
Section 11.4. In the case of any redemption of Securities prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
and an Opinion of Counsel evidencing compliance with such restriction.

      SECTION 11.3 Selection of Securities to be Redeemed.

      If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days

Trustee, from the Outstanding Securities of such series not previously called
for redemption, by such method as the Trustee shall deem fair and appropriate
and which may provide for the selection for redemption of a portion of the
principal amount of any Security of such series. If less than all the Securities
of such series and of a specified tenor are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series and specified tenor
not previously called for redemption in accordance with the preceding sentence.

      The Trustee shall promptly notify the Company in writing of the Securities
selected for partial redemption and the principal amount thereof to be redeemed.
For all purposes of this Indenture, unless the context otherwise requires, all
provisions relating to the redemption of Securities shall relate, in the case of
any Security redeemed or to be redeemed only in part, to the portion of the
principal amount of such Security which has been or is to be redeemed. If the
Company shall so direct, Securities registered in the name of the Company, any
Affiliate or any Subsidiary thereof shall not be included in the Securities
selected for redemption.

      SECTION 11.4 Notice of Redemption.

      Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not later than the 30th day, and not earlier than the 60th day, prior to
the Redemption Date, to each Holder of Securities to be redeemed, at the address
of such Holder as it appears in the Securities Register.

      With respect to Securities of each series to be redeemed, each notice of
redemption shall identify the Securities (including CUSIP number(s)) to be
redeemed and shall state:

      (a) the Redemption Date;

      (b) the Redemption Price or if the Redemption Price cannot be calculated
prior to the time the notice is required to be sent, the estimate of the
Redemption Price provided pursuant to the Indenture together with a statement
that it is an estimate and that the actual Redemption Price will be calculated
on the third Business Day prior to the Redemption Date (if such an estimate of
the Redemption Price is given, a subsequent notice shall be given as set forth
above setting forth the Redemption Price promptly following the calculation
thereof);

      (c) if less than all Outstanding Securities of such particular series and
having the same terms are to be redeemed, the identification (and, in the case
of partial redemption, the respective principal amounts) of the particular
Securities to be redeemed;

      (d) that on the Redemption Date, the Redemption Price will become due and
payable upon each such Security or portion thereof, and that interest thereon,
if any, shall cease to accrue on and after said date;

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

      (f) that the redemption is for a sinking fund, if such is the case; and

                                       65
<PAGE>

      (g) such other provisions as may be required in respect of the terms of a
particular series of Securities.

      Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's written request, by
the Trustee in the name and at the expense of the Company and shall not be
irrevocable. 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, a failure to give such notice by mail or any
defect in the notice to the Holder of any Security designated for redemption as
a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security.

      SECTION 11.5 Deposit of Redemption Price.

      Prior to 10:00 a.m. New York City time on the Redemption Date specified in
the notice of redemption given as provided in Section 11.4, the Company will
deposit with the Trustee or with one or more Paying Agents (or if the Company is
acting as its own Paying Agent, the Company will segregate and hold in trust as
provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and any accrued interest (including Additional Interest) on, all the
Securities which are to be redeemed on that date.

      SECTION 11.6 Payment of Securities Called for Redemption.

      If any notice of redemption has been given as provided in Section 11.4,
the Securities or portion of Securities with respect to which such notice has
been given shall become due and payable on the date and at the place or places
stated in such notice at the applicable Redemption Price, together with accrued
interest (including any Additional Interest) to the Redemption Date. On
presentation and surrender of such Securities at a Place of Payment in said
notice specified, the said securities or the specified portions thereof shall be
paid and redeemed by the Company at the applicable Redemption Price, together
with accrued interest (including any Additional Interest) to the Redemption
Date; provided, however, that, unless otherwise specified as contemplated by
Section 3.1, installments of interest whose Stated Maturity is on or prior to
the Redemption Date will be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant record dates according to their terms and the provisions of Section
3.8.

      Upon presentation of any Security redeemed in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder thereof, at
the expense of the Company, a new Security or Securities of the same series, of
authorized denominations, in aggregate principal amount equal to the unredeemed
portion of the Security so presented and having the same Original Issue Date,
Stated Maturity and terms. If a Global Security is so surrendered, such new
Security (subject to Section 3.5) will also be a new Global Security.

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

      SECTION 11.7 Right of Redemption of Securities Initially Issued to a
Citizens Trust.

      In the case of the Securities of a series initially issued to a Citizens
Trust, if specified as contemplated by Section 3.1, the Company, at its option,
may redeem such Securities (i) on or after the date 10 years after the Original
Issue Date of such Securities, in whole at any time or in part from time to
time, or (ii) in whole (but not in part) at any time within 90 days following
the occurrence of a Tax Event or Capital Treatment Event in respect of such
Citizens Trust, in each case at a Redemption Price specified as contemplated by
Section 3.1.

                                  ARTICLE XII

                                 SINKING FUNDS

      SECTION 12.1 Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

      The minimum amount of any sinking fund payment provided for by the terms
of any Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any sinking fund payment in excess of such minimum amount
which is permitted to be made by the terms of such Securities of any series is
herein referred to as an "optional sinking fund payment." If provided for by the
terms of any Securities of any series, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 12.2. Each sinking
fund payment shall be applied to the redemption (or purchase by tender or
otherwise) of Securities of any series as provided for by the terms of such
Securities.

      SECTION 12.2 Satisfaction of Sinking Fund Payments with Securities.

      In lieu of making all or any part of a mandatory sinking fund payment with
respect to any Securities of a series in cash, the Company may at its option, at
any time no more than 16 months and no less than 45 days prior to the date on
which such sinking fund payment is due, deliver to the Trustee Securities of
such series (together with the unmatured coupons, if any, appertaining thereto)
theretofore purchased or otherwise acquired by the Company, except Securities of
such series that have been redeemed through the application of mandatory or
optional sinking fund payments pursuant to the terms of the Securities of such
series, accompanied by a Company Order instructing the Trustee to credit such
obligations and stating that the Securities of such series were originally
issued by the Company by way of bona fide sale or other negotiation for value;
provided that the Securities to be so credited have not been previously so
credited. The Securities to be so credited shall be received and credited for
such purpose by the Trustee at the redemption price for such Securities, as
specified in the Securities so to be redeemed, for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

      SECTION 12.3 Redemption of Securities for Sinking Fund.

      Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such Securities pursuant to the terms of such Securities, the portion thereof,
if any, which is to be satisfied by payment of cash in the currency in which the
Securities of such series are payable (except as provided pursuant to Section
3.1) and the portion thereof, if any, which is to be satisfied by delivering and
crediting Securities pursuant to Section 12.2 and will also deliver to the
Trustee any Securities to be so delivered. Such Officers' Certificate shall be
irrevocable and upon its delivery the Company shall be obligated to make the
cash payment or payments therein referred to, if any, on or before the
succeeding sinking fund payment date. In the case of the failure of the Company
to deliver such Officers' Certificate (or, as required by this Indenture, the
Securities and coupons, if any, specified in such Officers' Certificate) by the
due date therefor, the sinking fund payment due on the succeeding sinking fund
payment date for such series shall be paid entirely in cash and shall be
sufficient to redeem the principal amount of the Securities of such series
subject to a mandatory sinking fund payment without the right to deliver or
credit securities as provided in Section 12.2 and without the right to make the
optional sinking fund payment with respect to such series at such time.

      Any sinking fund payment or payments (mandatory or optional) made in cash
plus any unused balance of any preceding sinking fund payments made with respect
to the Securities of any particular series shall be applied by the Trustee (or
by the Company if the Company is acting as its own Paying Agent) on the sinking
fund payment date on which such payment is made (or, if such payment is made
before a sinking fund payment date, on the sinking fund payment date immediately
following the date of such payment) to the redemption of Securities of such
series at the Redemption Price specified in such Securities with respect to the
sinking fund. Any sinking fund monies not so applied or allocated by the Trustee
(or, if the Company is acting as its own Paying Agent, segregated and held in
trust by the Company as provided in Section 10.3) for such series and together
with such payment (or such amount so segregated) shall be applied in accordance
with the provisions of this Section 12.3. Any and all sinking fund monies with
respect to the Securities of any particular series held by the Trustee (or if
the Company is acting as its own Paying Agent, segregated and held in trust as
provided in Section 10.3) on the last sinking fund payment date with respect to
Securities of such series and not held for the payment or redemption of
particular Securities of such series shall be applied by the Trustee (or by the
Company if the Company is acting as its own Paying Agent), together with other
monies, if necessary, to be deposited (or segregated) sufficient for the
purpose, to the payment of the principal of the Securities of such series at
Maturity. The Trustee shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 11.3 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 11.4. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Section 11.6. On or before each sinking fund payment
date, the Company shall pay to the Trustee (or, if the Company is acting as its
own Paying Agent, the Company shall segregate and hold in trust as provided in
Section 10.3) in cash a sum in the currency in which Securities of such series
are payable (except as provided pursuant to Section 3.1) equal to the principal,
premium, if any, and any interest accrued to the Redemption Date for Securities
or portions thereof to be redeemed on such sinking fund payment date pursuant to
this Section 12.3.

                                       68
<PAGE>

      Neither the Trustee nor the Company shall redeem any Securities of a
series with sinking fund monies or mail any notice of redemption of Securities
of such series by operation of the sinking fund for such series during the
continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring
as a consequence of this paragraph) with respect to the Securities of such
series, except that if the notice of redemption shall have been provided in
accordance with the provisions hereof, the Trustee (or the Company, if the
Company is then acting as its own Paying Agent) shall redeem such Securities if
cash sufficient for that purpose shall be deposited with the Trustee (or
segregated by the Company) for that purpose in accordance with the terms of this
Article XII. Except as aforesaid, any monies in the sinking fund for such series
at the time when any such default or Event of Default shall occur and any monies
thereafter paid into such sinking fund shall, during the continuance of such
default or Event of Default, be held as security for the payment of the
Securities and coupons, if any, of such series; provided, however, that in case
such default or Event of Default shall have been cured or waived herein, such
monies shall thereafter be applied on the next sinking fund payment date for the
Securities of such series on which such monies may be applied pursuant to the
provisions of this Section 12.3.

                                  ARTICLE XIII

                           SUBORDINATION OF SECURITIES

      SECTION 13.1 Securities Subordinate to Senior Indebtedness.

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

      SECTION 13.2 No Payment When Senior Indebtedness in Default; Payment Over
of Proceeds Upon Dissolution, Etc.

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

      In the event of (a) any insolvency, bankruptcy, receivership, liquidation,
reorganization, readjustment, composition or other similar proceedings relating
to the Company, its creditors or its property, (b) any proceeding for the
liquidation, dissolution or other winding up of the Company, voluntary or
involuntary, whether or not involving insolvency or bankruptcy proceedings, (c)
any assignment by the Company for the benefit of creditors or (d) any other

                                       69
<PAGE>

marshalling of the assets of the Company (each such event, if any, herein
sometimes referred to as a "Proceeding"), all Senior Indebtedness (including any
interest thereon accruing after the commencement of any such proceedings) shall
first be paid in full before any payment or distribution, whether in cash,
securities or other property, shall be made to any Holder of any of the
Securities on account thereof. Any payment or distribution, whether in cash,
securities or other property (other than securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment the payment
of which is subordinate, at least to the extent provided in this Article XIII,
as such may be modified pursuant to Section 3.1 with respect to any series of
Securities with respect to the indebtedness evidenced by the Securities, to the
payment of all Senior Indebtedness at the time outstanding and to any securities
issued in respect thereof under any such plan of reorganization or
readjustment), which would otherwise (but for this Article XIII, as such may be
modified pursuant to Section 3.1 with respect to any series of Securities) be
payable or deliverable in respect of the Securities of any series shall be paid
or delivered directly to the holders of Senior Indebtedness in accordance with
the priorities then existing among such holders until all Senior Indebtedness
(including any interest thereon accruing after the commencement of any
Proceeding) shall have been paid in full.

      In the event of any Proceeding, after payment in full of all sums owing
with respect to Senior Indebtedness, the Holders of the Securities, together
with the holders of any obligations of the Company ranking on a parity with the
Securities, shall be entitled to be paid from the remaining assets of the
Company the amounts at the time due and owing on account of unpaid principal of
(and premium, if any) and interest on the Securities and such other obligations
before any payment or other distribution, whether in cash, property or
otherwise, shall be made on account of any capital stock or any obligations of
the Company ranking junior to the Securities and such other obligations.

      In the event that, notwithstanding the foregoing, any payment or
distribution of any character or any security, whether in cash, securities or
other property (other than securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment the payment of which is
subordinate, at least to the extent provided in these subordination provisions
with respect to the indebtedness evidenced by the Securities, to the payment of
all Senior Indebtedness at the time outstanding and to any securities issued in
respect thereof under any such plan of reorganization or readjustment), shall be
received by the Trustee or any Holder in contravention of any of the terms
hereof and before all Senior Indebtedness shall have been paid in full, such
payment or distribution or security shall be received in trust for the benefit
of, and shall be paid over or delivered and transferred to, the holders of the
Senior Indebtedness at the time outstanding in accordance with the priorities
then existing among such holders for application to the payment of all Senior
Indebtedness remaining unpaid, to the extent necessary to pay all such Senior
Indebtedness in full. In the event of the failure of the Trustee or any Holder
to endorse or assign any such payment, distribution or security, each holder of
Senior Indebtedness is hereby irrevocably authorized to endorse or assign the
same.

      The Trustee and Holders will take such action (including, without
limitation, the delivery of this Indenture to an agent for the holders of Senior
Indebtedness or consent to the filing of a financing statement with respect
hereto) as may, in the opinion of counsel designated by the holders of a
majority in principal amount of the Senior Indebtedness at the time outstanding,
be

                                       70
<PAGE>

necessary or appropriate to assure the effectiveness of the subordination
effected by these provisions.

      The provisions of this Section 13.2 shall not impair any rights,
interests, remedies or powers of any secured creditor of the Company in respect
of any security interest the creation of which is not prohibited by the
provisions of this Indenture.

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

      SECTION 13.3 Payment Permitted If No Default.

      Nothing contained in this Article or elsewhere in this Indenture, or in
any of the Securities, shall prevent (a) the Company at any time, except during
the conditions described in the first paragraph of Section 13.2 or the pendency
of any Proceeding referred to in Section 13.2, from making payments at any time
of principal of (and premium, if any) or interest (including Additional
Interest) on the Securities, or (b) the application by the Trustee of any monies
deposited with it hereunder to the payment of or on account of the principal of
(and premium, if any) or interest (including any Additional Interest) on the
Securities or the retention of such payment by the Holders, if, at the time of
such application by the Trustee, it did not have knowledge that such payment
would have been prohibited by the provisions of this Article.

      SECTION 13.4 Subrogation to Rights of Holders of Senior Indebtedness.

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

<PAGE>

      SECTION 13.5 Provisions Solely to Define Relative Rights.

      The provisions of this Article are and are intended solely for the purpose
of defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to
or shall (a) impair, as between the Company and the Holders of the Securities,
the obligations of the Company, which are absolute and unconditional, to pay to
the Holders of the Securities the principal of (and premium, if any) and
interest (including any Additional Interest) on the Securities as and when the
same shall become due in accordance with their terms; or (b) affect the relative
rights against the Company of the Holders of the Securities and creditors of the
Company other than their rights in relation to the holders of Senior
Indebtedness; or (c) prevent the Trustee or the Holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture including, without limitation, filing and voting claims in any
Proceeding, subject to the rights, if any, under this Article of the holders of
Senior Indebtedness to receive cash, property and securities otherwise payable
or deliverable to the Trustee or such Holder.

      SECTION 13.6 Trustee to Effectuate Subordination.

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

      SECTION 13.7 No Waiver of Subordination Provisions.

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

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

                                       72
<PAGE>

      SECTION 13.8 Notice to Trustee.

      The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee, agent or
representative therefor; 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 monies may become payable
for any purpose (including, without limitation, the payment of the principal of
(and premium, if any) or interest (including any Additional Interest) on any
Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such monies and to apply
the same to the purpose for which they were received and shall not be affected
by any notice to the contrary which may be received by it within two Business
Days prior to such date.

      Subject to the provisions of Section 6.1, the Trustee shall be entitled to
conclusively rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee or
attorney-in-fact therefor) to establish that such notice has been given by a
holder of Senior Indebtedness (or a trustee or attorney-in-fact therefor). In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of 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, 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 13.9 Reliance on Judicial Order or Certificate of Liquidating
Agent.

      Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 6.1, and the
Holders of the Securities shall be entitled to conclusively rely upon any order
or decree entered by any court of competent jurisdiction in which such
Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee for the benefit of creditors, agent or
other Person making such payment or distribution, delivered to the Trustee or to
the Holders of Securities, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of the Senior
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.

      SECTION 13.10 Trustee Not Fiduciary for Holders of Senior Indebtedness.

      The Trustee, in its capacity as trustee under this Indenture, shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall
not be liable to any such holders if it shall in good faith mistakenly pay over
or distribute to Holders of Securities or to the Company or to any other Person
cash, property or securities to which any holders of Senior Indebtedness shall
be entitled by virtue of this Article or otherwise. With respect to the holders
of Senior Indebtedness, the Trustee undertakes to perform or to observe only
such of its covenants or obligations as are specifically set forth in this
Article and no implied covenants or obligations with respect to holders of
Senior Indebtedness shall be read into this Indenture against the Trustee.

      SECTION 13.11 Rights of Trustee as Holder of Senior Indebtedness;
Preservation of Trustee's Rights.

set forth in this Article with respect to any Senior Indebtedness which may at

requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee.

     SECTION 2.1. Pursuant to Sections 2.1 and 3.1 of the Indenture, there is
hereby established a series of Securities, the terms of which shall be as
follows:

          (a) Designation. The Securities of this series shall be known and
     designated as the "7.50% Junior Subordinated Debentures due September 15,
     2066" of the Company (the "Debentures"). The Debentures initially shall be
     issued to Citizens Capital Trust I, a Delaware statutory trust (the
     "Trust"). The Trust Agreement for the Trust shall be the Amended and
     Restated Trust Agreement, dated as of October 3, 2006, among the Company,
     as Depositor, U.S. Bank Trust National Association, as Delaware Trustee,
     U.S. Bank National Association, as Property Trustee, and the Administrative

     Agreement, dated as of October 3, 2006, between the Company and U.S. Bank
     National Association, as Guarantee Trustee.

          (b) Aggregate Principal Amount. The maximum aggregate principal amount
     of the Debentures which may be authenticated and delivered under the
     Indenture and this Supplemental Indenture is $150,010,000 (except for
     Debentures authenticated and delivered upon registration of transfer of, or
     exchange for, or in lieu of, other Debentures pursuant to Section 3.4, 3.6,
     3.7, 9.6 or 11.6 of the Indenture).

          (c) Denominations. The Debentures will be issued only in fully
     registered form, and the authorized minimum denomination of the Debentures
     shall be $25 principal amount and any integral multiple thereof.

          (d) Maturity. The principal amount of the Debentures shall be payable
     in full on September 15, 2066 subject to and in accordance with the
     provisions of the Indenture and this Supplemental Indenture.

                                       -3-

<PAGE>

          (e) Rate of Interest. The rate at which the Debentures shall bear
     interest will be 7.50% per annum; the date from which such interest shall
     accrue is October 3, 2006; the Interest Payment Dates (as defined in the
     Indenture) on which such interest shall be payable are March 15, June 15,
     September 15 and December 15 of each year, commencing December 15, 2006.
     Interest payments not paid when due will themselves accrue Additional
     Interest at the annual rate of 7.50% on the amount of unpaid interest, to
     the extent permitted by law, compounded quarterly. The amount of interest
     payable for any period will be computed on the basis of a 360-day year
     comprised of twelve 30-day months. The amount of interest payable for any
     period shorter than a full quarterly period will be computed on the basis
     of a 30-day month and, for periods of less than a month, the actual number
     of days elapsed per 30-day month. If an Interest Payment Date falls on a
     day that is not a Business Day, the interest payment shall be postponed to
     the next succeeding Business Day, without any interest or other payment in
     respect of such delay.

          (f) To Whom Interest Payable. Interest will be payable to the person
     in whose name the Debentures are registered at the close of business on the
     Regular Record Date next preceding the Interest Payment Date, except that,
     interest payable on the Stated Maturity of the principal of the Debentures
     shall be paid to the Person to whom principal is paid.

          (g) Option to Defer Interest Payments. Interest payments on the
     Debentures shall be subject to deferral to the extent and in the manner
     provided in Section 3.12 of the Indenture for one or more Extension Periods
     of up to 40 consecutive quarterly periods. If the Company has deferred
     interest payments under this clause (g) for an Extension Period consisting
     of 40 consecutive quarterly periods, no interest will be due or payable on
     the Interest Payment Date relating to the last such quarterly period;
     provided, however, that all accrued and unpaid interest (including any
     Additional Interest) will become due and payable on the next subsequent
     Interest Payment Date. With respect to each Interest Payment Date, the
     Company shall deliver to the Trustee written notice of any optional
     deferral pursuant to this clause (g) at least 10 Business Days and not more
     than 60 Business Days prior to such Interest Payment Date (which notice
     requirement shall be in lieu of, and not in addition to, the notice
     requirement described in the last sentence of the first paragraph of
     Section 3.12 of the Indenture, which shall not apply to the Debentures).

          (h) Events of Default and Remedies. For the Debentures, Sections 5.1
     and 5.2 of the Indenture shall not apply and shall be replaced with Annex A
     attached hereto.

     any) and interest on the Debentures will be made at the corporate trust

     private debts; provided, however, that at the option of the Company payment
     of interest may be made (i) by check mailed to the address of the Person
     entitled thereto as such address shall appear in the Securities Register or
     (ii) by wire transfer in immediately available funds at such place and to
     such account as may be designated by the Person entitled thereto as
     specified in the Securities Register; provided, further, that, for so long
     as the Trust appears on the Securities Register as a Holder of

                                       -4-

<PAGE>

     Debentures and in a timely manner has provided wire transfer instructions
     to the Company with respect to payments on the Debentures, all payments to
     the Trust as Holder of Debentures shall be made by wire transfer in
     immediately available funds to the account specified in such wire transfer
     instructions. The office where the Debentures may be presented or
     surrendered for payment and the office where the Debentures may be
     surrendered for transfer or exchange and where notices and demands to or
     upon the Company in respect of the Debentures and the Indenture may be
     served shall be the Corporate Trust Office. The Trustee shall act as Paying
     Agent.

          (j) Redemption. The Debentures are redeemable at the option of the
     Company, subject to the terms and conditions of Article XI of the Indenture
     and subject to the Company having received prior approval from the FRB if
     then required under applicable capital guidelines or policies of the FRB,
     at 100% of their principal amount plus accrued and unpaid interest (1) in
     whole or in part, on one or more occasions at any time on or after
     September 15, 2011, or (2) in whole at any time if a Special Event has
     occurred and is continuing and the Company cannot cure the Special Event by
     some reasonable action, in which case the Company may redeem the Debentures
     within 90 days following the occurrence of the Special Event.

          (k) Sinking Fund. The Debentures shall not be subject to any sinking
     fund or analogous provisions.

          (l) Forms. The Debentures shall be substantially in the form of Annex
     B attached hereto, with such modifications thereto as may be approved by
     the authorized officer executing the same. The Trust Agreement shall be
     substantially in the form of Annex C attached hereto, with such
     modifications thereto as may be approved by the authorized officer
     executing the same. The Guarantee Agreement shall be substantially in the
     form of Annex D attached hereto, with such modifications thereto as may be
     approved by the authorized officer executing the same.

          (m) Subordination. The subordination provisions of Article XIII of the
     Indenture shall apply; provided, however, that for the purposes of the
     Debentures (but not for the purposes of any other Securities unless
     specifically set forth in the terms of such Securities),

          (1)  "Senior Indebtedness" shall mean any obligation of the Company to
               its creditors, whether now outstanding or subsequently incurred,
               other than any obligation as to which, in the instrument creating
               or evidencing the obligation or pursuant to which the obligation
               is outstanding, it is provided that such obligation is not Senior
               Indebtedness; provided, however, that Senior Indebtedness does
               not include (a) Pari Passu Securities, (b) any accounts payable
               or other liability to trade creditors (including guarantees
               thereof or instruments evidencing such liabilities) or (c) any
               accrued liabilities arising in the ordinary course of business.

          (2)  "Pari Passu Securities" shall mean (i) indebtedness (A) that
               qualifies or is issued to financing vehicles issuing securities
               that qualify as Tier 1 capital of the Company under the capital
               guidelines of the FRB and (B) the terms of which provide that
               such indebtedness ranks equally with the Debentures in right of
               payment and upon liquidation; and (ii) guarantees of indebtedness
               described in clause (i) or securities issued by one or more
               financing vehicles described in clause (i)(A).

         (b) "Debenture Default", wherever used herein with respect to
Debentures, means any one of the following events (whatever the reason for such
Default and whether it shall be occasioned by the provisions of Article XIII or
be voluntary or involuntary or be effected by operation of law or pursuant to
any judgment, decree or order of any court or any order, rule or regulation or
any administrative or governmental body):

          (1) an Event of Default with respect to Debentures; or

                                       A-1

<PAGE>

          (2) a default in the payment of any installment of interest (including
     any Additional Interest) on any Debenture when such interest becomes due
     and payable and such default continues for a period of 30 days (subject to
     the deferral of any due date in the case of an Extension Period), or

          (3) a default in the payment of the principal of (or premium, if any,
     on) any Debenture at its Maturity; or

          (4) failure on the part of the Company duly to observe or perform any
     other of the covenants or agreements on the part of the Company in the
     Debentures or in the Indenture for a period of 90 days after the date on
     which written notice of such failure, requiring the Company to remedy the
     same, shall have been given to the Company by the Trustee by registered or
     certified mail or to the Company and the Trustee by the Holders of at least
     25% in aggregate principal amount of the Outstanding Debentures.

     Section 5.2. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default described in clause (1) or (2) of Section 5.1(a)
with respect to the Debentures occurs and is continuing, then and in every such
case the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Outstanding Debentures may declare the principal amount of all the
Debentures to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), provided that, for so long as
the Trust is the holder of all of the Outstanding Debentures, if, upon such an
Event of Default, the Trustee fails to declare the principal of all the
Outstanding Debentures to be immediately due and payable, the holders of at
least 25% in aggregate Liquidation Amount (as defined in the Trust Agreement) of
the Capital Securities then outstanding shall have the right to make such
declaration by a notice in writing to the Company and the Trustee; and upon any
such declaration such principal amount (or specified portion thereof) of and the
accrued interest (including any Additional Interest) on all the Debentures shall
become immediately due and payable. Payment of principal and interest (including
any Additional Interest) on the Debentures shall remain subordinated to the
extent provided in the Indenture notwithstanding that such amount shall become
immediately due and payable as herein provided. If an Event of Default described
in Section 5.1(a)(3) or 5.1(a)(4) with respect to Debentures occurs, the
principal amount of all the Debentures shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable.

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

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

               (A) all overdue installments of interest (including any
          Additional Interest) on all the Debentures,

                                       A-2

<PAGE>

               (B) the principal of (and premium, if any, on) the Debentures
          that have become due otherwise than by such declaration of
          acceleration and interest thereon at the rate borne by the Debentures,
          and

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

          (2) all Events of Default with respect to the Debentures, other than
     the non-payment of the principal of the Debentures that has become due
     solely by such acceleration, have been cured or waived as provided in
     Section 5.13.

CUSIP NO. [__]

     CITIZENS BANKING CORPORATION, a corporation organized and existing under
the laws of the State of Michigan (hereinafter called the "Company," which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay U.S. Bank National Association, as
Property Trustee of CITIZENS CAPITAL TRUST I, or registered assigns, the
principal sum of ________ dollars ($_______) on September 15, 2066. The Company
further promises to pay interest on said principal sum from October 3, 2006 or
from the most recent interest payment date (each such date, an "Interest Payment
Date") on which interest has been paid or duly provided for, quarterly (subject
to deferral as set forth herein) in arrears on March 15, June 15, September 15
and December 15 of each year, commencing December 15, 2006, at the rate of 7.50%
per annum, until the principal hereof shall have become due and payable, and on
any overdue principal and (without duplication and to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment of
interest at the same rate per annum, compounded quarterly. The amount of
interest payable for any period will be computed on the basis of a 360-day year
comprised of twelve 30-day months. The amount of interest payable for any period
shorter than a full quarterly period will be computed on the basis of a 30-day
month period and, for periods of less than a month, the actual number of days
elapsed per 30-day month. In the event that any date on which interest is
payable on this Security is not a Business Day, then a payment of the interest
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay). A
"Business Day" shall mean any day other than (i) a Saturday or Sunday, (ii) a
day on which banking institutions in The City of New York are authorized or
required by law or executive order to remain closed or (iii) a day on which the
Corporate Trust Office of the Property Trustee or the designated office of the
Property Trustee under the Trust Agreement hereinafter referred to for Citizens
Capital Trust I, is closed for business. 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 Security (or
one or more Predecessor Securities) is registered at the close of business on
the Regular Record Date for such interest installment, which shall be (i) the
Business Day next preceding such Interest Payment Date if this Security is
issued in the form of a Global Security, or (ii) the fifteenth (15) day (whether
or not a Business Day) preceding such Interest

----------
(1)  This form assumes that Citizens Capital Trust I is the sole holder of
     record of the Debentures. If Debentures are held by any other Person,
     pursuant to Section 2.1 of the Indenture the Company shall establish by
     Board Resolution a revised form of Debenture.

                                       B-1

<PAGE>

Payment Date if this Security is not issued in the form of a Global Security.
Any such interest installment not so punctually paid or duly provided for shall
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than ten (10) days prior to such Special Record Date, or be paid at any
time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

     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 this
Security to defer payment of interest on this Security for up to forty
consecutive quarterly interest payment periods with respect to each deferral
period (each an "Extension Period"), but shall pay all interest then accrued and
unpaid (together with interest thereon to the extent permitted by applicable
law, compounded quarterly at the rate specified in this Security) on the first
Interest Payment Date following the termination of such Extension Period;
provided, however, that no Extension Period shall extend beyond the Stated
Maturity of the principal of this Security. Upon termination of any such
Extension Period and upon the payment of all accrued and unpaid interest
(including any Additional Interest) then due, the Company may elect to begin a
new Extension Period, subject to the above requirements. No interest shall be
due and payable during an Extension Period except on the first Interest Payment
Date thereafter.

     The Company shall not pay on any Interest Payment Date interest that has
accrued on this Security during the quarterly interest period immediately
preceding such Interest Payment Date, unless the Company pays therewith all
accrued and unpaid interest (including any Additional Interest) at such time
outstanding on this Security, including without limitation accrued and unpaid
interest that has been deferred pursuant to the provisions described in the
preceding paragraph.

     During any such Extension Period and until all accrued but unpaid interest
is paid in full, the Company shall not, and shall not permit any Subsidiary of
the Company to, (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 capital stock or (ii) make any payment of principal of or interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank pari passu with or junior in interest to this Security or
(iii) make any guarantee payments with respect to any guarantee by the Company
of the debt securities of any Subsidiary of the Company if such guarantee ranks
pari passu with or junior in interest to the Security (other than (a)
repurchases, redemptions or other acquisitions of shares of capital stock of the
Company in connection with any employment contract, benefit plan or other
similar arrangement with or for the benefit of any one or more employees,
officers, directors or consultants, in connection with a dividend reinvestment
or shareholder stock purchase plan or in connection with the issuance of capital
stock of the Company (or securities convertible into or exercisable for such
stock) as consideration in an acquisition transaction entered into prior to the
Extension Period, (b) as a result of an exchange or conversion of any class of
series of the Company's capital stock for any other indebtedness for any class
or series of the Company's

                                       B-2

<PAGE>

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 the implementation or amendment of
the Company shareholders' rights plan (or any successor thereto), or the
issuance of rights, stock or other property under any such rights plan, or the
redemption or repurchase of rights pursuant to, or (e) any dividend in the form
of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock).

     Payment of principal of (and premium, if any) and interest on this Security
will be made at the office or agency of the Company maintained for that purpose
in the United States, in such coin or currency of the United States of America
as at the time of payment is legal tender for payment of public and private
debts; provided, however, that at the option of the Company payment of interest
may be made (i) by check mailed to the address of the Person entitled thereto as
such address shall appear in the Securities Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated in writing at least fifteen (15) days before the relevant Interest
Payment Date by the Person entitled thereto as specified in the Securities
Register; provided, further, that for so long as Citizens Capital Trust I
appears on the Securities Register as a Holder of Debentures and in a timely
manner has provided wire transfer instructions to the Company with respect to
payments on the Debentures, all payments to Citizens Capital Trust I as Holder
of Debenture shall be made by wire transfer in immediately available funds to
the account specified in such wire transfer instructions.

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinated and subject in right of payments to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto. Each Holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
actions as may be necessary or appropriate to 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 upon said provisions.

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

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

                               REVERSE OF SECURITY

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under a Junior Subordinated Indenture, dated as of October 3, 2006, as
supplemented by the First Supplemental Indenture, dated as of October 3, 2006
(herein together called the "Indenture"), between the Company and U.S. Bank
National Association, as Trustee (herein called the "Trustee," which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Trustee, the Company and the Holders of the Securities, and of the terms
upon which the Securities are, and are to be, authenticated and delivered. This
Security is one of the series designated on the face hereof, limited in
aggregate principal amount of $150,010,000 issuable on one or more occasions.

     All terms used in this Security that are defined in the Indenture or in the
Amended and Restated Trust Agreement, dated as of October 3, 2006 (the "Trust
Agreement"), for Citizens Capital Trust I, among Citizens Banking Corporation,
as Depositor, and the Trustees named therein, shall have the meanings assigned
to them in the Indenture or the Trust Agreement, as the case may be.

     The Company may at any time, at its option, on or after September 15, 2011,
and subject to the terms and conditions of Article XI of the Indenture and
Section 2.1(j) of the First Supplemental Indenture, and subject to prior
approval by the Board of Governors of the Federal Reserve System if then
required, redeem this Security 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.

     Upon the occurrence and during the continuation of a Tax Event, Investment
Company Event or a Regulatory Capital 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 Regulatory Capital Event redeem this
Security, in whole but not in part, subject to the provisions of Article XI of
the 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.

     The Indenture contains provisions for satisfaction and discharge of the
entire indebtedness of this Security upon compliance by the Company of certain
conditions set forth in the Indenture.

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

                                       B-5

<PAGE>

series, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holders of this Security and of any Security
issued upon the registration and transfer hereof or in exchange hereof or in
lieu hereof, whether or not notation of such consent or waiver is made upon this
Security.

     As provided in and subject to the provisions of the Indenture, if an Event
of Default with respect to the Securities of this series at the time Outstanding
occurs and is continuing, then and in every such case the Trustee or the Holders
of not less that 25% in principal amount of the Outstanding Securities of this
series may declare the principal amount of all the Securities of this series to
be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by the Holders), provided that, in the case of the
Securities of this series issued to a Trust, if upon an Event of Default, the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of this series fails to declare the principal of all the
Securities of this series to be immediately due and payable, the holders of at
least 25% in aggregate Liquidation Amount of the Capital Securities then
outstanding shall have such right by a notice in writing to the Company and the
Trustee; and upon any such declaration the principal amount of and the accrued
interest (including Additional Interest) on all the Securities of this series
shall become immediately due and payable, provided that the payment of principal
and interest (including Additional Interest) on such Securities shall remain
subordinated to the extent provided in Article XIII of the Indenture and Section
2.1(m) of the First Supplemental Indenture.

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

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Securities Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company maintained under Section 10.2 of the Indenture duly
endorsed by, or accompanied by written instrument of transfer in form
satisfactory to the Company and the Securities Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees. No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

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

     The Securities of this series are issuable only in registered form without
coupons in denominations of $25 and in any multiple thereof. As provided in the
Indenture and subject to

                                       B-6

<PAGE>

certain limitations therein set forth, Securities of this series are
exchangeable for like aggregate principal amount of Securities of such series of
a different authorized denomination, as requested by the Holder surrendering the
same.

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

     THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS
OF LAWS PRINCIPLES THEREOF.

     This is one of the Securities referred to in the mentioned Indenture.
