REPLACEMENT CAPITAL COVENANT, dated as of October 3, 2006 (this
"Replacement Capital Covenant"), by Citizens Banking Corporation, a Michigan
corporation (together with its successors and assigns, the "Corporation"), in
favor of and for the benefit of each Covered Debtholder (as defined below).

                                    RECITALS

               A. On the date hereof, the Corporation is issuing $150,010,000
aggregate principal amount of its 7.50% Junior Subordinated Debentures due 2066
(the "Subordinated Debentures") to Citizens Funding Trust I (the "Trust").

               B. On the date hereof, the Trust is issuing $150,000,000
aggregate liquidation amount of its 7.50% Enhanced Trust Preferred Securities
(the "Trust Preferred Securities" and together with the Subordinated Debentures,
the "Securities").

               C. This Replacement Capital Covenant is the "Replacement Capital
Covenant" referred to in the Prospectus Supplement, dated September 26, 2006,
relating to the Securities.

               D. The Corporation is entering into and disclosing the content of
this Replacement Capital Covenant in the manner provided below with the intent
that the covenants provided for in this Replacement Capital Covenant be
enforceable by each Covered Debtholder and that the Corporation be estopped from
disregarding the covenants in this Replacement Capital Covenant, in each case to
the fullest extent permitted by applicable law.

               E. The Corporation acknowledges that reliance by each Covered
Debtholder upon the covenants in this Replacement Capital Covenant is reasonable
and foreseeable by the Corporation and that, were the Corporation to disregard
its covenants in this Replacement Capital Covenant, each Covered Debtholder
would have sustained an injury as a result of its reliance on such covenants.

               NOW, THEREFORE, the Corporation hereby covenants and agrees as
follows in favor of and for the benefit of each Covered Debtholder.

               SECTION 1. Definitions. Capitalized terms used in this
Replacement Capital Covenant (including the Recitals) have the meanings set
forth in Schedule I hereto.

               SECTION 2. Limitations on Redemption and Repurchase of
Securities. The Corporation hereby promises and covenants to and for the benefit
of each Covered Debtholder that the Corporation shall not redeem or repurchase,
and no Subsidiary of the Corporation shall purchase, all or any part of the
Securities prior to September 15, 2036 except to the extent that (a) the
Corporation has obtained the prior approval of the Federal Reserve if such
approval is then required under the Federal Reserve's capital guidelines
applicable to bank holding companies and (b) the applicable redemption,
repurchase or purchase price does not exceed the sum of the following amounts:




                  (i) the Applicable Percentage of the aggregate amount of net
         cash proceeds received by the Corporation and its Subsidiaries since
         the most recent Measurement Date from the sale of Common Stock and
         rights to acquire Common Stock; plus

                  (ii) 100% of the aggregate amount of net cash proceeds
         received by the Corporation and its Subsidiaries since the most recent
         Measurement Date from the sale of Mandatorily Convertible Preferred
         Stock and Debt Exchangeable for Equity to Persons other than the
         Corporation and its Subsidiaries; plus

                  (iii) 100% of the aggregate amount of net cash proceeds
         received by the Corporation and its Subsidiaries since the most recent
         Measurement Date from the sale of Qualifying Capital Securities to
         Persons other than the Corporation and its Subsidiaries.

               SECTION 3. Covered Debt. (a) The Corporation represents and
warrants that the Initial Covered Debt is Eligible Debt.

               (a) On or during the 30-day period immediately preceding any
Redesignation Date with respect to the Covered Debt then in effect, the
Corporation shall identify the series of Eligible Debt that will become the
Covered Debt on and after such Redesignation Date in accordance with the
following procedures:

                  (i) the Corporation shall identify each series of its and its
         Depository Institution Subsidiaries' then outstanding long-term
         indebtedness for money borrowed that is Eligible Debt;

                  (ii) if only one series of the Corporation's then outstanding
         long-term indebtedness for money borrowed is Eligible Debt, such series
         shall become the Covered Debt commencing on the related Redesignation
         Date;

                  (iii) if the Corporation has more than one outstanding series
         of long-term indebtedness for money borrowed that is Eligible Debt,
         then the Corporation shall identify the series that has the latest
         occurring final maturity date as of the date the Corporation is
         applying the procedures in this Section 3(b) and such series shall
         become the Covered Debt on the related Redesignation Date;

                  (iv) if the Corporation has no outstanding series of long-term
         indebtedness for money borrowed that is Eligible Debt, and its Largest
         Depository Institution Subsidiary has only one outstanding series of
         long-term indebtedness for money borrowed that is Eligible Debt, such
         series shall become the Covered Debt commencing on the related
         Redesignation Date;

                  (v) if the Corporation has no outstanding series of long-term
         indebtedness for money borrowed that is Eligible Debt, but its Largest
         Depository Institution Subsidiary has more than one outstanding series
         of long-term



                                       -2-


         indebtedness for money borrowed that is Eligible Debt, then the
         Corporation shall identify the series that has the latest occurring
         final maturity date as of the date the Corporation is applying the
         procedures in this Section 3(b) and such series shall become the
         Covered Debt on the related Redesignation Date;

                  (vi) the series of outstanding long-term indebtedness for
         money borrowed that is determined to be Covered Debt pursuant to clause
         (ii), (iii), (iv) or (v) above shall be the Covered Debt for purposes
         of this Replacement Capital Covenant for the period commencing on the
         related Redesignation Date and continuing to but not including the
         Redesignation Date as of which a new series of outstanding long-term
         indebtedness is next determined to be the Covered Debt pursuant to the
         procedures set forth in this Section 3(b); and

                  (vii) in connection with such identification of a new series
         of Covered Debt, the Corporation shall, as provided for in Section
         3(c), give a notice and file with the Commission a current report on
         Form 8-K including or incorporating by reference this Replacement
         Capital Covenant as an exhibit within the time frame provided for in
         such section.

               (b) Notice. In order to give effect to the intent of the
Corporation described in Recital C, the Corporation covenants that (i)
simultaneously with the execution of this Replacement Capital Covenant or as
soon as practicable after the date hereof, it shall (x) give notice to the
Holders of the Initial Covered Debt, in the manner provided in the indenture
relating to the Initial Covered Debt, of this Replacement Capital Covenant and
the rights granted to such Holders hereunder and (y) file a copy of this
Replacement Capital Covenant with the Commission as an exhibit to a Form 8-K
under the Securities Exchange Act; (ii) so long as the Corporation is a
reporting company under the Securities Exchange Act, the Corporation will
include in each annual report filed with the Commission on Form 10-K under the
Securities Exchange Act a description of the covenant set forth in Section 2 and
identify the series of long-term indebtedness for borrowed money that is Covered
Debt as of the date such Form 10-K is filed with the Commission; (iii) if a
series of the Corporation's or one of its Depository Institution Subsidiary's
long-term indebtedness for money borrowed (1) becomes Covered Debt or (2) ceases
to be Covered Debt, give notice of such occurrence within 30 days to the holders
of such long-term indebtedness for money borrowed in the manner provided for in
the indenture, fiscal agency agreement or other instrument under which such
long-term indebtedness for money borrowed was issued and report such change in a
current report on Form 8-K including or incorporating by reference this
Replacement Capital Covenant, and in the Corporation's next quarterly report on
Form 10-Q or annual report on Form 10-K, as applicable; (iv) if, and only if,

Act, post on its website the information otherwise required to be included in

               SECTION 4. Termination, Amendment and Waiver. (a) The obligations
of the Corporation pursuant to this Replacement Capital Covenant shall remain in
full force and effect until the earlier date (the "Termination Date") to occur
of (i) the date, if any, on which the Holders of a majority by principal amount
of the then-effective series of Covered Debt consent or agree in writing to the
termination of this Replacement Capital Covenant and the obligations of the
Corporation hereunder and (ii) the date on which neither the Corporation nor any
of its Depository Institution Subsidiaries has any series of outstanding
Eligible Senior Debt or Eligible Subordinated Debt (in each case without giving
effect to the rating requirement in clause (b) of the definition of each such
term). From and after the Termination Date, the obligations of the Corporation
pursuant to this Replacement Capital Covenant shall be of no further force and
effect.

               (b) This Replacement Capital Covenant may be amended or
supplemented from time to time by a written instrument signed by the Corporation
with the consent of the Holders of a majority by principal amount of the
then-effective series of Covered Debt, provided that this Replacement Capital
Covenant may be amended or supplemented from time to time by a written
instrument signed only by the Corporation (and without the consent of the
Holders of the then-effective series of Covered Debt) if (i) such amendment
eliminates Common Stock or Mandatorily Convertible Preferred Stock as a security
or securities covered by clause (i) of Section 2 and the Corporation has been
advised in writing by a nationally recognized independent accounting firm that
there is more than an insubstantial risk that the failure to do so would result
in a reduction in the Corporation's earnings per share as calculated for
financial reporting purposes or (ii) such amendment or supplement is not adverse
to the Holders of the then-effective series of Covered Debt and an officer of
the Corporation has delivered to the Holders of the then-effective series of
Covered Debt in the manner provided for in the indenture, fiscal agency
agreement or other instrument with respect to such Covered Debt a written
certificate stating that, in his or her determination, such amendment or
supplement is not adverse to the Holders of the then-effective series of Covered
Debt.

               (c) For purposes of Sections 4(a) and 4(b), the Holders whose
consent or agreement is required to terminate, amend or supplement the
obligations of the Corporation under this Replacement Capital Covenant shall be
the Holders of the then-effective Covered Debt as of a record date established
by the Corporation that is not more than 30 days prior to the date on which the
Corporation proposes that such termination, amendment or supplement becomes
effective.

               SECTION 5. Miscellaneous. (a) THIS REPLACEMENT CAPITAL COVENANT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK.

               (b) This Replacement Capital Covenant shall be binding upon the
Corporation and its successors and assigns and shall inure to the benefit of the
Covered Debtholders as they exist from time-to-time (it being understood and
agreed by the Corporation that any Person who is a Covered Debtholder at the
time such Person acquires, holds or sells Covered Debt shall retain its status
as a Covered Debtholder for




                                       -4-


so long as the series of long-term indebtedness for borrowed money owned by such
Person is Covered Debt and, if such Person initiates a claim or proceeding to
enforce its rights under this Replacement Capital Covenant after the Corporation
has violated its covenants in Section 2 and before the series of long-term
indebtedness for money borrowed held by such Person is no longer Covered Debt,
such Person's rights under this Replacement Capital Covenant shall not terminate
by reason of such series of long-term indebtedness for money borrowed no longer
being Covered Debt).

               (c) All demands, notices, requests and other communications to
the Corporation under this Replacement Capital Covenant shall be deemed to have
been duly given and made if in writing and (i) if served by personal delivery
upon the Corporation, on the day so delivered (or, if such day is not a Business
Day, the next succeeding Business Day), (ii) if delivered by registered post or
certified mail, return receipt requested, or sent to the Corporation by a
national or international courier service, on the date of receipt by the
Corporation (or, if such date of receipt is not a Business Day, the next
succeeding Business Day), or (iii) if sent by telecopier, on the day telecopied,
or if not a Business Day, the next succeeding Business Day, provided that the
telecopy is promptly confirmed by telephone confirmation thereof, and in each
case to the Corporation at the address set forth below, or at such other address
as the Corporation may thereafter notify to Covered Debtholders or post on its
website as the address for notices under this Replacement Capital Covenant:

securities or combination of securities (together in this definition, "such
securities"), provisions in the related transaction documents requiring the
Corporation to issue (or use commercially reasonable efforts to issue) APM
Qualifying Securities raising eligible proceeds at least equal to the deferred
Distributions on such securities and apply the proceeds to pay unpaid
Distributions on such securities, commencing not later than (i) the first
Distribution Date on which the Corporation pays current Distributions on such
securities or (ii) the fifth anniversary of the commencement of the deferral or
other non-payment of Distributions on such securities, and that:

                  (a) permit the Corporation to pay current Distributions on any
         Distribution Date out of any source of funds but require the issuer to

         Alternative Payment Mechanism;

                  (b) if deferral of Distributions continues for more than one

         least one year after payment of deferred (and uncancelled)
         Distributions in accordance with the Alternative Payment Mechanism;

                  (c) notwithstanding sub-clause (a), if the Federal Reserve
         disapproves the issuer's sale of APM Qualifying Securities, permit the

         from any source without a breach of its obligations under the
         transaction documents;

                  (d) if the Federal Reserve does not disapprove the
         Corporation's issuance and sale of APM Qualifying Securities but
         disapproves the use of the proceeds thereof to pay deferred
         Distributions, permit the Corporation to use such proceeds for other
         purposes and to continue to defer Distributions without a breach of its
         obligations under the transaction documents; and

                  (e) limit the obligation of the Corporation to issue (or use

         of net proceeds received by the Corporation from those sales and
         available for payment of deferred Distributions on such securities
         shall be applied to such securities on a pro rata basis in proportion

         Distributions attributable to the first five years of any deferral
         period even if the amount referred to in clause (i) subsequently

         of Common Stock or the number of outstanding shares of Common Stock;
         and

                  (b) if, due to a Market Disruption Event or otherwise, the

Securities, within two years of a failure to satisfy one or more financial tests
set forth in the terms of such securities or related transaction agreements, in
an amount such that the net proceeds of such sale at least equal the amount of
unpaid Distributions on such securities (including without limitation all
deferred and accumulated amounts) and in either case require the application of
the net proceeds of such sale to pay such unpaid Distributions, provided that if
the APM Qualifying Securities issued and sold are non-cumulative perpetual

outstanding in the case of securities not permitting the issuance and sale
pursuant to the provisions described in clause (A) above of securities other
than Common Stock or rights to acquire Common Stock or (y) two years of
accumulated and unpaid Distributions in all other cases. No remedy other than
Permitted Remedies will arise by the terms of such securities or related
transaction agreements in favor of the holders of such securities as a result of
the issuer's failure to pay Distributions because of the Mandatory Trigger
Provision or as a result of the issuer's exercise of its right under an Optional
Deferral and Forgiveness Provision until Distributions have been deferred for
one or more Distribution Periods that total together at least ten years. It is
acknowledged that as of the date hereof the Federal Reserve has not permitted a
Mandatory Trigger
