         Floating Rate Junior Subordinated Deferrable Interest Debenture

                                       of

                                First Banks, Inc.

                               September 28, 2007

         First Banks,  Inc., a Missouri  corporation  (the "Company"  which term
includes any successor Person under the Indenture  hereinafter referred to), for
value  received  promises  to  pay  to  Wilmington  Trust  Company,  not  in its
individual capacity but solely as Institutional Trustee for First Bank Statutory
Trust XI (the "Holder") or registered assigns,  the principal sum of ten million
three hundred ten thousand dollars ($10,310,000.00) on December 15, 2037, and to
pay interest on said  principal  sum from  September  28, 2007, or from the most
recent Interest  Payment Date (as defined below) to which interest has been paid
or duly  provided  for,  quarterly  (subject to deferral as set forth herein) in
arrears on March 15, June 15,  September  15 and  December 15 of each year or if
such day is not a Business Day, then the next succeeding Business Day (each such
date, an "Interest Payment Date") (it being understood that interest accrues for
any such non-Business Day),  commencing on the Interest Payment Date in December
2007, at an annual rate equal to 8.08063%  beginning on (and including) the date
of original  issuance and ending on (but excluding) the Interest Payment Date in
December 2007 and at an annual rate for each successive period beginning on (and
including)  the Interest  Payment  Date in December  2007,  and each  succeeding
Interest  Payment  Date,  and  ending  on (but  excluding)  the next  succeeding
Interest  Payment Date (each a "Distribution  Period"),  equal to 3-Month LIBOR,
determined as described  below,  plus 2.85% (the "Coupon Rate"),  applied to the
principal amount hereof, until the principal hereof is paid or duly provided for
or made  available  for  payment,  and on any  overdue  principal  and  (without
duplication and to the extent that payment of such interest is enforceable under
applicable  law) on any overdue  installment of interest  (including  Additional
Interest) at the Interest Rate in effect for each applicable period,  compounded
quarterly,  from the dates  such  amounts  are due  until  they are paid or made
available  for  payment.  The amount of interest  payable for any period will be
computed on the basis of the actual  number of days in the  Distribution  Period
concerned  divided by 360. The interest  installment so payable,  and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in the
Indenture,  be paid to the Person in whose name this  Debenture  (or one or more
Predecessor  Securities)  is  registered at the close of business on the regular
record date for such interest installment,  which shall be fifteen Business Days
prior to the day on which the relevant  Interest  Payment Date occurs.  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 be paid to
the Person in whose name this Debenture (or one or more Predecessor  Securities)
is registered at the close of business on a special record date.

         "3-Month  LIBOR" as used  herein,  means the London  interbank  offered
interest rate for three-month U.S. dollar deposits  determined by the Trustee in
the following  order of priority:  (i) the rate  (expressed as a percentage  per
annum) for U.S. dollar  deposits  having a three-month  maturity that appears on
Reuters Page LIBOR01 as of 11:00 a.m. (London time) on the related Determination
Date  ("Reuters  Page  LIBOR01"  means the display  designated  as  "LIBOR01" on
Reuters or such other page as may replace  Reuters  Page LIBOR01 on that service
or such other  service or services as may be nominated  by the British  Bankers'
Association  as the  information  vendor for the  purpose of  displaying  London
interbank offered rates for U.S. dollar  deposits);  (ii) if such rate cannot be
identified  on the related  Determination  Date,  the Trustee  will  request the
principal London offices of four leading banks in the London interbank market to
provide such banks' offered  quotations  (expressed as percentages per annum) to
prime banks in the London  interbank  market for U.S.  dollar  deposits having a
three-month  maturity as of 11:00 a.m. (London time) on such Determination Date.
If at least two  quotations  are provided,  3-Month LIBOR will be the arithmetic
mean of such quotations; (iii) if fewer than two such quotations are provided as
requested  in clause (ii) above,  the Trustee  will  request four major New York
City banks to provide such banks' offered  quotations  (expressed as percentages
per annum) to leading  European banks for loans in U.S. dollars as of 11:00 a.m.
(London time) on such  Determination  Date. If at least two such  quotations are
provided, 3-Month LIBOR will be the arithmetic mean of such quotations; and (iv)
if fewer than two such  quotations  are  provided as  requested  in clause (iii)
above,  3-Month  LIBOR will be a 3-Month  LIBOR  determined  with respect to the
Distribution Period immediately  preceding such current  Distribution Period. If
the rate for U.S. dollar  deposits having a three-month  maturity that initially
appears on Reuters  Page LIBOR01 as of 11:00 a.m.  (London  time) on the related
Determination Date is superseded on the Reuters Page LIBOR01 by a corrected rate
by 12:00 noon (London time) on such Determination  Date, then the corrected rate
as so substituted on the  applicable  page will be the applicable  3-Month LIBOR
for such Determination Date. As used herein, "Determination Date" means the date
that is two London  Banking  Days  (i.e.,  a business  day in which  dealings in
deposits  in  U.S.  dollars  are  transacted  in the  London  interbank  market)
preceding the commencement of the relevant Distribution Period.
<PAGE>

         The Interest Rate for any Distribution Period will at no time be higher
than the maximum rate then permitted by New York law as the same may be modified
by United States law.

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

         The principal of and interest on this Debenture shall be payable at the
office or agency of the Trustee (or other paying agent appointed by the Company)
maintained  for that  purpose in any coin or  currency  of the United  States of
America  that at the time of payment is legal  tender for  payment of public and
private debts; provided,  however, that payment of interest may be made by check
               --------   -------
mailed to the registered holder at such address as shall appear in the Debenture
Register if a request for a wire  transfer by such holder has not been  received
by the Company or by wire transfer to an account appropriately designated by the
holder  hereof.  Notwithstanding  the  foregoing,  so long as the holder of this
Debenture  is the  Institutional  Trustee,  the payment of the  principal of and
interest on this Debenture will be made in immediately  available  funds at such
place and to such account as may be designated by the Trustee.

         So long  as no  Acceleration  Event  of  Default  has  occurred  and is
continuing,  the Company  shall have the right,  from time to time,  and without
causing an Event of Default,  to defer payments of interest on the Debentures by
extending  the interest  payment  period on the  Debentures at any time and from
time  to  time  during  the  term of the  Debentures,  for up to 20  consecutive
quarterly  periods (each such extended  interest  payment period,  an "Extension
Period"),  during  which  Extension  Period no  interest  (including  Additional
Interest)  shall be due and payable  (except any Additional Sums that may be due
and  payable).  No  Extension  Period may end on a date  other than an  Interest
Payment Date.  During an Extension  Period,  interest will continue to accrue on
the Debentures,  and interest on such accrued  interest will accrue at an annual
rate equal to the Interest Rate in effect for such Extension Period,  compounded
quarterly  from the date such  interest  would have been payable were it not for
the Extension  Period, to the extent permitted by law (such interest referred to
herein as "Additional  Interest").  At the end of any such Extension  Period the
           --------------------
Company  shall pay all  interest  then  accrued  and  unpaid  on the  Debentures
(together  with  Additional  Interest  thereon);   provided,  however,  that  no
                                                   --------   -------
Extension Period may extend beyond the Maturity Date; provided further, however,
                                                      -------- -------  -------
that  during any such  Extension  Period,  the  Company  shall not and shall not
permit  any  Affiliate  to  engage  in  any of the  activities  or  transactions
described  on  the  reverse  side  hereof  and in the  Indenture.  Prior  to the
termination of any Extension Period, the Company may further extend such period,
provided  that  such  period   together  with  all  such  previous  and  further
consecutive  extensions  thereof  shall  not  exceed  20  consecutive  quarterly
periods,  or extend  beyond  the  Maturity  Date.  Upon the  termination  of any
Extension  Period and upon the payment of all accrued  and unpaid  interest  and
Additional Interest, the Company may commence a new Extension Period, subject to
the foregoing requirements.  No interest or Additional Interest shall be due and
payable  during  an  Extension  Period,  except  at the end  thereof,  but  each
installment  of interest that would  otherwise  have been due and payable during
such Extension Period shall bear Additional Interest.  The Company must give the
Trustee  notice of its  election to begin or extend an  Extension  Period by the
close of business at least 15 Business  Days prior to the Interest  Payment Date
with respect to which interest on the Debentures  would have been payable except
for the election to begin or extend such Extension Period.

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

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

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

                              REVERSE OF DEBENTURE

         This  Debenture  is  one  of  the  floating  rate  junior  subordinated
deferrable interest debentures of the Company,  all issued or to be issued under
and pursuant to the Indenture dated as of September 28, 2007 (the  "Indenture"),
duly  executed  and  delivered  between the Company  and the  Trustee,  to which
Indenture reference is hereby made for a description of the rights,  limitations
of rights,  obligations,  duties and immunities  thereunder of the Trustee,  the
Company  and the  holders  of the  Debentures.  The  Debentures  are  limited in
aggregate principal amount as specified in the Indenture.

         Upon the  occurrence and  continuation  of a Special Event prior to the
Interest  Payment  Date in December  2012,  the Company  shall have the right to
redeem the Debentures in whole,  but not in part, at any Interest  Payment Date,
within 120 days following the  occurrence of such Special Event,  at the Special
Redemption Price.

         In addition, the Company shall have the right to redeem the Debentures,
in whole or in  part,  but in all  cases in a  principal  amount  with  integral
multiples of  $1,000.00,  on any Interest  Payment Date on or after the Interest
Payment Date in December 2012, at the Redemption Price.

         Prior to  10:00  a.m.  New York  City  time on the  Redemption  Date or
Special  Redemption  Date,  as  applicable,  the Company  will  deposit with the
Trustee  or with one or more  paying  agents an amount  of money  sufficient  to
redeem on the Redemption Date or the Special Redemption Date, as applicable, all
the Debentures so called for redemption at the appropriate  Redemption  Price or
Special Redemption Price.

         If all,  or less than  all,  the  Debentures  are to be  redeemed,  the
Company  will give the  Trustee  notice  not less than 45 nor more than 60 days,
respectively,  prior to the  Redemption  Date or  Special  Redemption  Date,  as
applicable,  as to the aggregate  principal  amount of Debentures to be redeemed
and the Trustee shall select,  in such manner as in its sole discretion it shall
deem  appropriate  and fair,  the  Debentures  or portions  thereof (in integral
multiples of $1,000.00) to be redeemed.

         Notwithstanding  the  foregoing,  any  redemption  of Debentures by the
Company  shall be subject  to the  receipt  of any and all  required  regulatory
approvals.

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

         The  Indenture  contains  provisions  permitting  the  Company  and the
Trustee,  with the  consent  of the  holders  of not  less  than a  majority  in
aggregate principal amount of the Debentures at the time outstanding, to execute
supplemental  indentures for the purpose of adding any provisions to or changing
in any manner or  eliminating  any of the provisions of this Indenture or of any
supplemental  indenture  or of modifying in any manner the rights of the holders
of the Debentures;  provided, however, that no such supplemental indenture shall
                    --------  -------
without  the  consent of the  holders of each  Debenture  then  outstanding  and
affected  thereby (i) change the fixed maturity of any Debenture,  or reduce the
principal  amount thereof or any premium  thereon,  or reduce the rate or extend
the time of  payment  of  interest  thereon,  or reduce  any  amount  payable on
redemption  thereof or make the  principal  thereof or any  interest  or premium
thereon  payable  in any  coin or  currency  other  than  that  provided  in the
Debentures,  or impair or affect the right of any  Securityholder  to  institute
suit for payment thereof or impair the right of repayment, if any, at the option
of the holder, or (ii) reduce the aforesaid percentage of Debentures the holders
of which are required to consent to any such supplemental indenture.

         The Indenture  also  contains  provisions  permitting  the holders of a
majority in aggregate principal amount of the Debentures at the time outstanding
on behalf of the  holders  of all of the  Debentures  to waive  (or  modify  any
previously  granted  waiver of) any past  default or Event of  Default,  and its
consequences,  except a default (a) in the payment of principal of, premium,  if
any,  or  interest  on any of the  Debentures,  (b) in respect of  covenants  or
provisions  hereof or of the  Indenture  which  cannot be  modified  or  amended
without the consent of the holder of each Debenture affected,  or (c) in respect
of the covenants contained in Section 3.9 of the Indenture;  provided,  however,
                                                             --------   -------
that if the  Debentures  are held by the Trust or a trustee of such trust,  such
waiver or  modification  to such waiver shall not be effective until the holders

<PAGE>

of a majority in Liquidation  Amount of Trust Securities of the Trust shall have
consented to such waiver or modification to such waiver, provided, further, that
                                                         --------  -------
if the consent of the holder of each  outstanding  Debenture is  required,  such
waiver shall not be effective  until each holder of the Trust  Securities of the
Trust shall have  consented  to such waiver.  Upon any such waiver,  the default
covered  thereby  shall be deemed to be cured for all purposes of the  Indenture
and the Company, the Trustee and the holders of the Debentures shall be restored
to their former positions and rights hereunder, respectively; but no such waiver
shall extend to any  subsequent  or other  default or Event of Default or impair
any right consequent thereon. Whenever any default or Event of Default hereunder
shall have been waived as permitted by the  Indenture,  said default or Event of
Default shall for all purposes of the  Debentures and the Indenture be deemed to
have been cured and to be not continuing.

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

         The Company has agreed that if Debentures  are initially  issued to the
Trust or a  trustee  of such  Trust in  connection  with the  issuance  of Trust
Securities by the Trust (regardless of whether Debentures continue to be held by
such  Trust) and (i) there shall have  occurred  and be  continuing  an Event of
Default, (ii) the Company shall be in default with respect to its payment of any
obligations under the Capital Securities  Guarantee,  or (iii) the Company shall
have  given  notice  of its  election  to  defer  payments  of  interest  on the
Debentures by extending the interest  payment period as provided herein and such
Extension  Period,  or any  extension  thereof,  shall be  continuing,  then the
Company  shall not,  and shall not allow any  Affiliate  of the  Company to, (x)
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 its  Affiliates'  capital  stock  (other than  payments of dividends or
distributions  to the Company or payments of  dividends  from direct or indirect
subsidiaries  of the Company to their parent  corporations,  which also shall be
direct or indirect  subsidiaries of the Company) or make any guarantee  payments
with  respect  to the  foregoing  or (y) make any  payment  of  principal  of or
interest  or  premium,  if any,  on or  repay,  repurchase  or  redeem  any debt
securities of the Company or any Affiliate  that rank pari passu in all respects
with or junior in  interest  to the  Debentures  (other  than,  with  respect to
clauses (x) and (y) above, (1) 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
one or more employees,  officers, directors or consultants, in connection with a
dividend  reinvestment or stockholder  stock purchase plan or in connection with
the issuance of capital stock of the Company (or securities  convertible into or
exercisable  for  such  capital  stock)  as   consideration  in  an  acquisition
transaction  entered into prior to the applicable  Extension Period, if any, (2)
as a  result  of any  exchange  or  conversion  of any  class or  series  of the
Company's  capital  stock (or any capital  stock of a subsidiary of the Company)
for any class or series of the Company's capital stock or of any class or series

         The  Debentures  are issuable  only in  registered,  certificated  form
without coupons and in minimum  denominations of $100,000.00 and any multiple of
$1,000.00 in excess  thereof.  As provided in the  Indenture  and subject to the

Debenture  Register of the Company.  Upon due  presentment  for  registration of

office or agency of the  Company  maintained  for such  purpose as  provided  in

<PAGE>

Section 3.2 of the  Indenture,  the Company  shall  execute,  the Company or the
Trustee  shall  register  and the  Trustee  or the  Authenticating  Agent  shall
authenticate  and make  available for delivery in the name of the  transferee or
transferees  a  new  Debenture  for  a  like  aggregate  principal  amount.  All
Debentures  presented  for  registration  of transfer or for exchange or payment
shall (if so required by the Company or the Trustee or the Authenticating Agent)
be duly endorsed by, or be accompanied by a written instrument or instruments of
transfer  in  form   satisfactory  to,  the  Company  and  the  Trustee  or  the
Authenticating Agent duly executed by the holder or his attorney duly authorized
in writing.  No service charge shall be made for any exchange or registration of
transfer of Debentures,  but the Company or the Trustee may require payment of a
sum  sufficient to cover any tax, fee or other  governmental  charge that may be
imposed in connection therewith.

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

         No recourse for the payment of the principal of or premium,  if any, or
interest  on any  Debenture,  or for any claim  based  thereon or  otherwise  in
respect  thereof,  and no  recourse  under or upon any  obligation,  covenant or
agreement of the Company in the Indenture or in any supplemental  indenture,  or
in  any  such  Debenture,  or  because  of  the  creation  of  any  indebtedness
represented  thereby,  shall  be  had  against  any  incorporator,  stockholder,
employee,  officer or director, as such, past, present or future, of the Company
or of any  successor  Person of the  Company,  either  directly  or through  the
Company  or any  successor  Person  of the  Company,  whether  by  virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise,  it being expressly  understood that all such liability is
hereby  expressly  waived and released as a condition of, and as a consideration
for, the execution of the Indenture and the issue of the Debentures.

         Capitalized terms used and not defined in this Debenture shall have the
meanings  assigned in the Indenture dated as of the date of original issuance of
this Debenture between the Trustee and the Company.

         THE INDENTURE AND THE DEBENTURES  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF
LAW PRINCIPLES THEREOF.
