         Floating Rate Junior Subordinated Deferrable Interest Debenture

                                       of

                           AmericanWest Bancorporation

                               September 26, 2002

         AmericanWest Bancorporation, a Washington corporation (the "Company"
which term includes any successor Person under the Indenture hereinafter
referred to), for value received promises to pay to State Street Bank and Trust
Company of Connecticut, National Association, not in its individual capacity but
solely as Institutional Trustee for AmericanWest Statutory Trust I (the
"Holder") or registered assigns, the principal sum of ten million three hundred
ten thousand dollars ($10,310,000.00) on September 26, 2032, and to pay interest
on said principal sum from September 26, 2002, or from the most recent interest
payment date (each such date, an "Interest Payment Date") to which interest has
been paid or duly provided for, quarterly (subject to deferral as set forth
herein) in arrears on March 26, June 26, September 26 and December 26 of each
year commencing December 26, 2002, at an annual rate equal to 5.220% beginning
on (and including) the date of original issuance and ending on (but excluding)
December 26, 2002 and at an annual rate for each successive period beginning on
(and including) December 26, 2002, 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 3.400% (the "Coupon Rate"); provided, however, that prior to September 26,
2007, the Coupon Rate shall not exceed 11.90%, 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) on
any overdue installment of interest at the same rate per annum, 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. In the event that any date on which interest is
payable

                                       2

<PAGE>

on this Debenture 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.
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 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
Telerate Page 3750 as of 11:00 a.m. (London time) on the related Determination
Date ("Telerate Page 3750" means the display designated as "Page 3750" on the
Dow Jones Telerate Service or such other page as may replace Page 3750 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 Telerate Page 3750 as of 11:00
a.m. (London time) on the related Determination Date is superseded on the
Telerate Page 3750 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.

         The Coupon 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)).

                                       3

<PAGE>

         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 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. No Extension Period may 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 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 at least 5 Business Days prior to the regular record
date (as such term is used in Section 2.8 of the Indenture) immediately
preceding 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 26, 2002 (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
September 26, 2007, 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 September 26,
2007, 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, together with accrued interest to the Redemption Date
or Special Redemption Date, as applicable.

         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 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 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 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 make any guarantee payments with respect to the
foregoing or (y) make any payment of principal of or interest

                                       7

<PAGE>

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 of the Company's indebtedness for any
class or series of the Company's capital stock, (3) 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, (4) any declaration of a dividend in connection with any
stockholders' rights plan, or the issuance of rights, stock or other property
under any stockholders' rights plan, or the redemption or repurchase of rights
pursuant thereto, (5) 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 and any
cash payments in lieu of fractional shares issued in connection therewith, or
(6) payments under the Capital Securities Guarantee).

         The Debentures are issuable only in registered, certificated form
without coupons and in minimum denominations of $500,000.00 and any multiple of
$1,000.00 in excess thereof. As provided in the Indenture and subject to the
transfer restrictions and limitations as may be contained herein and therein
from time to time, this Debenture is transferable by the holder hereof on the
Debenture Register of the Company. Upon due presentment for registration of
transfer of any Debenture at the Principal Office of the Trustee or at any
office or agency of the Company maintained for such purpose as provided in
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
