MANAGEMENT DISCUSSION AND ANALYSIS

The following discussion is provided for the consolidated operations of
InterWest Bancorp, Inc. (InterWest Bancorp), which includes its wholly owned
subsidiaries (collectively InterWest). As of September 30, 1999, InterWest
Bancorp's wholly owned subsidiaries were InterWest Bank, Pacific Northwest
Bank and Kittitas Valley Bank, N.A. The purpose of this discussion is to
focus on significant factors concerning InterWest's financial condition and
results of operations. This discussion should be read along with the
consolidated financial statements (including notes thereto) for an
understanding of the following discussion and analysis.

    During fiscal year 1999, InterWest has continued its strategy to increase
its emphasis on commercial banking and the goal of becoming a statewide
institution. InterWest is a financial services company that provides a
variety of products and services for both individual and business customers.
InterWest will continue to change the composition of the loan portfolio and
the deposit base. InterWest increased commercial real estate and commercial
loan balances outstanding during fiscal year 1999. Additionally, transaction
deposit balances outstanding increased while reducing reliance on
certificates of deposit for funding asset growth. These changes were designed
to have a positive impact on net interest income and service fee revenue
while meeting the needs of InterWest's customers.

    InterWest has completed the acquisition of seven commercial banks since
1996. The acquisition of Central Bancorporation on August 31, 1996, was the
first of these acquisitions. Central's commercial banking subsidiaries,
Central Washington Bank and North Central Washington Bank, operated ten
offices in central Washington. At the acquisition date, Central had total
consolidated assets of $206.1 million, total loans receivable of $132.2
million, total deposits of $181.9 million and shareholders' equity of $17.1
million.

    On January 15, 1998, InterWest Bancorp acquired Puget Sound Bancorp, Inc.
(Puget), of Port Orchard, Washington. Puget's commercial banking subsidiary,
First National Bank of Port Orchard, operated three offices in western
Washington. At the acquisition date, Puget had total consolidated assets of
$53.1 million, total loans receivable of $38.7 million, total deposits of
$45.6 million, and shareholders' equity of $5.9 million. On October 15, 1998,
First National Bank of Port Orchard was merged into Pacific Northwest Bank.

    On June 15, 1998, InterWest Bancorp acquired Pacific Northwest Bank
(Pacific), of Seattle, Washington. At the acquisition date, Pacific operated
four offices in the metropolitan Seattle area of western Washington and had
total assets of $200.2 million, total loans receivable of $150.1 million,
total deposits of $170.2 million, and shareholders' equity of $16.8 million.

    On June 16, 1998, InterWest Bancorp acquired Pioneer Bancorp, Inc.
(Pioneer), of Yakima, Washington. Pioneer's commercial banking subsidiary,
Pioneer National Bank, operated five offices in central Washington. At the
acquisition date, Pioneer had total consolidated assets of $q108.4 million,
total loans receivable of $63.4 million, total deposits of $87.2 million, and
shareholders' equity of $9.3 million. On January 22, 1999, Pioneer National
Bank was merged into Pacific Northwest Bank.

    The acquisitions of Central, Puget, Pacific and Pioneer were accounted
for using the pooling-of-interests method. In accordance with generally
accepted accounting principles, prior period financial statements, as well as
management discussion and analysis have been restated as if the companies
were combined for all periods presented.

    On August 31, q1998, InterWest Bancorp acquired Kittitas Valley Bancorp,
Inc. (Kittitas), of Ellensburg, Washington. Kittitas' commercial banking
subsidiary, Kittitas Valley Bank, N.A., operates offices in central
Washington. At the acquisition date, Kittitas had total consolidated assets
of $47.4 million, total loans receivable of $27.9 million, total deposits of
$39.2 million and shareholders' equity of $4.3 million. This acquisition has
been accounted for using the purchase method. An application has been filed
to merge Kittitas Valley Bank, N.A. into Pacific Northwest Bank. It is
anticipated that the merger will be completed during the second quarter of
fiscal year 2000, following the approval of applicable regulatory authorities.

    Subsequent to fiscal year end on October 1, 1999, InterWest Bancorp
completed the acquisition of NBT Northwest Bancorp (NBT), of Tukwila,
Washington. NBT's commercial banking subsidiary, National Bank of Tukwila,
operates one office in south King County. Under the terms of this transaction,
NBT merged into InterWest Bancorp, with National Bank of Tukwila becoming a
wholly owned subsidiary of InterWest Bancorp. At the acquisition date, NBT had
total consolidated assets of $53.0 million, total loans receivable of $37.8
million, total deposits of $48.0 million and

                        INTERWEST 99 AR


shareholders' equity of $4.9 million. Each share of NBT common stock was
exchanged for 0.88 shares of InterWest Bancorp common stock. The transaction
resulted in the recording of approximately $9.7 million in goodwill by
InterWest Bancorp. This goodwill will be amortized using the straight-line
method over a period of twenty years. This acquisition was accounted for
using the purchase method and as such the accounts and operations of NBT and
National Bank of Tukwila have not been included in the September 30, 1999
consolidated financial statements.

    The following table summarizes pertinent information related to the
completed acquisitions:

</TABLE>

(1) Additionally, $6.4 million in cash was paid to Kittitas shareholders.


    On September 14, 1999, InterWest Bancorp entered into a definitive
agreement to acquire Liberty Bay Financial Corporation (Liberty) of Poulsbo,
Washington. Liberty's commercial banking subsidiary, North Sound Bank,
operates eight offices on the Olympic Peninsula in Washington state. As of
September 30, 1999, Liberty had total consolidated assets of $187.9 million,
total loans receivable of $127.5 million, total deposits of $166.3 million
and shareholder's equity of $20.2 million. The transaction is structured such
that shareholders of Liberty will receive 11 shares of InterWest Bancorp
common stock for each share of Liberty common stock if the average price of
InterWest Bancorp common stock is more than $21 per share for a short period
prior to closing. If the average price of InterWest Bancorp common stock for
a short period before closing is between $20 and $21 per share, the
shareholders of Liberty will receive shares of InterWest Bancorp common stock
with a value of $231 for each share of Liberty common stock. If the average
price of InterWest Bancorp common stock for a short period before closing is
less than $20 per share, InterWest Bancorp has the option of adjusting the
exchange ratio such that Liberty shareholders will receive shares of
InterWest Bancorp common stock with an equivalent value of $231 for each
share of Liberty common stock or terminating the definitive agreement. It is
anticipated that the acquisition will be completed during the spring of 2000,
following the approval of applicable regulatory authorities and the
shareholders of Liberty. The transaction will be accounted for using the
purchase method.

    A source of future growth may be through acquisitions. InterWest believes
that many other financial institutions are considering selling their
institutions for a variety of reasons, including lack of shareholder
liquidity, management succession issues, technology challenges, increasing
competition and potential changes with respect to the method of accounting
used for mergers and acquisitions. InterWest actively reviews proposals for
various acquisition opportunities. InterWest has a due diligence review
process to evaluate potential acquisitions and has established parameters for
potential acquisitions relating to market factors, financial performance and
certain non-financial factors. Successful completion of acquisitions by
InterWest depends on several factors, such as the availability of suitable
acquisition candidates, necessary regulatory and shareholder approval and
compliance with applicable capital requirements. No assurance can be made
that acquisition activity will continue in the future.

    Currently, InterWest conducts its business through 56 full-service
offices in western and central Washington state. Investments are available
through InterWest Financial Services, Inc. and insurance products are
available through InterWest Insurance Agency, Inc., wholly owned subsidiaries
of InterWest Bank.

RESULTS OF OPERATIONS

    InterWest's net income was $27.9 million in 1999, compared to $22.6
million in 1998 and $24.5 million in 1997. Diluted net income per share was

NET INTEREST INCOME  InterWest's net income is significantly affected by changes
in net interest income, which is the difference between interest income received
on loans receivable and other interest-earning assets and interest paid on
deposits and borrowings. InterWest's operations are sensitive to changes in
interest rates and the resulting impact on net interest income.

    Net interest income before the provision for losses on loans was $84.2
million in 1999, compared to $78.8 million in 1998 and $74.1 million in 1997.
The increase in net interest income from 1998 to 1999 was due to growth in
interest-earning assets and an increase in net interest margin. The increase in
net interest income from 1997 to 1998 was due to growth in interest-earning
assets that was partially offset by a decrease in net interest margin.

    Despite decreasing yields and increased competition, net interest margin,
which is net interest income divided by average interest-earning assets,
increased for fiscal year 1999 compared to fiscal year 1998. Net interest margin
was 3.64 percent in 1999, compared to 3.52 percent in 1998 and 3.70 percent in
1997. The increase in net interest margin compared to the prior year was
primarily the result of a decrease in the cost of funds. The cost of funds was
reduced due to changes in the composition of the deposit base, deposit product
pricing initiatives and a decrease in the cost of borrowed funds. InterWest's
deposit base changed with increases in the average balances outstanding of
non-interest-bearing deposits of $41.3 million and interest-bearing transaction
deposit balances of $82.3 million and a decrease in the average balance
outstanding of certificates of deposit of $55.5 million. The effect that the
decrease in the cost of funds had on net interest margin was partially offset by
a decrease in the yield earned on loans, securities and other interest-earning
assets compared to fiscal year 1998. The flat yield curve has continued to
decrease the yields earned and, as such, expansion of net interest margin.

    Interest income was $179.7 million in 1999, compared to $180.3 million in
1998 and $165.2 million in 1997. Interest income decreased from 1998 to 1999,
due to a decrease in the yield earned partially offset by an increase in
interest-earning assets. Interest income increased from 1997 to 1998, due to
growth in interest-earning assets that was partially offset by a decrease in the
yield earned.

    Interest expense was $95.5 million in 1999, compared to $101.5 million in
1998 and $91.1 million in 1997. Interest expense decreased from 1998 to 1999,
due to a decrease in the cost of funds that was partially offset by an increase
in interest-bearing liabilities. Interest expense increased from 1997 to 1998,
due to an increase in interest-bearing liabilities and an increase in the cost
of funds.

    During the second half of fiscal year 1999, the overall interest rate
environment increased. In periods of rising interest rates, InterWest's net
interest income and net interest margin may decrease as a greater amount of
interest-bearing liabilities are subject to more rapid repricing than
interest-earning assets. InterWest is taking the following steps to offset
rising interest rates and increase net interest income and net interest margin:
increasing commercial lending, reducing dependence on single-family residential
mortgage loans, and increasing non-interest-bearing and interest-bearing
transaction deposits.

     The following table presents, for the periods indicated, information
regarding average balances of assets and liabilities as well as the total
amounts of interest income from average interest-earning assets and interest
expense on average interest-bearing liabilities, resulting yield and cost
ratios, interest rate spread, ratio of interest-earning assets to
interest-bearing liabilities and net interest margin for InterWest.

PROVISION FOR LOSSES ON LOANS The provision for losses on loans was $2.0 million
in 1999, compared to $2.8 million in 1998 and $1.5 million in 1997. The
provision for losses on loans for 1998 included a merger-related provision of
$1.1 million. The merger-related provision was the result of conforming the
allowance for losses on loans methodologies of the acquired companies to that of
InterWest.

NON-INTEREST INCOME Non-interest income was $28.4 million in 1999, compared to
$26.5 million in 1998 and $18.6 million in 1997. The increase in non-interest
income from 1998 to 1999 was due to several factors. Investment product fees and
insurance commissions earned by InterWest Bank's non-bank subsidiaries:
InterWest Financial Services, Inc. and InterWest Insurance Agency, Inc.
increased $1.0 million from 1998 to 1999. The acquisition of Kittitas Valley
Bank, N.A. (KVB) increased non-interest income $0.7 million.

    Gains on the sale of loans were $8.1 million for 1999, compared to $10.4
million in 1998 and $4.2 million in 1997. In addition to loan sales, InterWest
sold the servicing rights for $530 million of fixed-rate single-family mortgage
loans that resulted in a gain of $2.8 million in 1999. These loan servicing
rights primarily related to loans sold by InterWest during 1998 and the first
half of 1999. The sale was initiated as a result of increasing long-term
interest rates and decreasing loan prepayment rates, which increased the value
of the servicing portfolio. The sale of loan servicing rights also created
servicing capacity for future loan growth.

    During 1998 and the first half of 1999, the low long-term interest rate
environment resulted in increased fixed-rate single-family residential mortgage
loan refinances and opportunities to sell these loans on the secondary market
for a premium. During the second half of 1999, long-term interest rates
increased and single-family mortgage loan originations decreased, and as a
result, sales of single-family mortgage loans declined as compared to 1998 and
the first half of 1999. Based on the current interest rate environment,
InterWest anticipates that single-family mortgage loan sales will remain at low
levels during 2000 relative to 1998 and the first half of 1999.

    The increase in non-interest income from 1997 to 1998 was primarily due
to an increase in the gain on sale of loans.

NON-INTEREST EXPENSE Non-interest expense was $68.1 million in 1999, compared to
$67.0 million in 1998 and $54.0 million in 1997. Non-interest expense for 1998
included $5.5 million of non-recurring merger-related charges. Excluding the
merger-related charges in 1998, non-interest expense increased $6.6 million from
1998 to 1999, representing an increase of 11 percent for 1999 compared to 1998
and 14 percent for 1998 compared to 1997, respectively.

    Excluding the merger-related charges incurred in 1998, InterWest's
efficiency ratio was 60.53 percent in 1999, compared to 58.40 percent in 1998
and 58.24 percent in 1997.

    The increase in non-interest expense for 1999 compared to 1998 was primarily
due to the acquisition of KVB and an increase in compensation and employee
benefits. Non-interest expense associated with KVB totaled $2.3 million
(including goodwill amortization) for 1999. Compensation and employee benefits
were $37.5 million in 1999, compared to $32.6 million in 1998 and $28.1 million
in 1997. The increase was primarily due to the increased focus on commercial
banking. Compensation expense also increased as a result of higher lending
volumes and transaction account deposit growth, which increased compensation
resulting from variable compensation plans.

    The increase in non-interest expense for 1998 as compared to 1997 was
primarily due to activities to develop the resources and infrastructure for
commercial banking growth. Key elements of commercial banking growth were the
development of credit administration and commercial lending support, the
addition of commercial lending officers and several experienced commercial
banking management personnel.

    As discussed previously, InterWest completed acquisitions of four commercial
banks during 1998 and an additional acquisition subsequent to end of 1999.
InterWest has not converted to a common data processing system nor have various
operating policies and procedures been integrated. Additionally, InterWest
currently conducts business using multiple names and bank charters. The
integration process has been delayed due to the focus of resources on Year 2000
issues and the process of selecting a common operating platform that will best
meet InterWest's future needs. It is anticipated that data and systems
conversions will commence in the latter part of fiscal year 2000. The
efficiencies available from eliminating duplication of administrative and
operational functions have not yet been realized from the acquisitions.

INCOME TAX EXPENSE Income tax expense was $14.6 million in 1999, compared to
$12.8 million in 1998 and $12.7 million in 1997. The effective tax rates were
34.4 percent in 1999, 36.2 percent in 1998 and 34.1 percent in 1997. The higher
effective tax rate in 1998 was primarily due to certain direct merger-related
expenses that are not deductible for federal income tax purposes.

REVIEW OF FINANCIAL CONDITION

InterWest's total consolidated assets were $2.580 billion as of September 30,
1999, compared to $2.448 billion as of September 30, 1998. This was an increase
of $132 million, or 5 percent.

SECURITIES AND OTHER INTEREST-EARNING ASSETS Securities and other
interest-earning assets, including securities available for sale, securities
held to maturity, FHLB stock, interest-bearing deposits in banks and federal
funds sold were $824.2 million as of September 30, 1999, compared to $826.4
million as of September 30, 1998. As of September 30, 1999, 91 percent of
InterWest's securities were classified as available for sale, an increase from
87 percent as of September 30, 1998. Management believes that a higher
percentage of securities classified as available for sale provides greater
flexibility to respond to interest rate changes and liquidity needs to fund loan
growth.

    InterWest maintains liquidity in accordance with an internal liquidity
policy. Liquidity levels may be increased or decreased depending upon the yields
on investment alternatives, management's judgment as to the attractiveness of
the yields then available in relation to other opportunities, and management's
expectation of the yield that will be available in the future. Management's
projections as to the short-term demand for funds to be used for loan
originations and other activities can also affect liquidity levels.

    Securities are categorized as held to maturity or available for sale, based
upon management's intent as to the ultimate disposition of each security
acquired. InterWest does not currently trade securities. Securities classified
as held to maturity are stated at amortized cost. Securities classified as
available for sale are reported at estimated fair value, with unrealized gains
and losses (net of income taxes) reported in accumulated other comprehensive
income, a separate component of shareholders' equity.

    The gross unrealized loss on securities available for sale has increased to
$24.7 million as of September 30, 1999, compared to $1.1 million as of September
30, 1998. This increase was primarily due to increasing interest rates during
1999.

    The following table sets forth the amortized cost and estimated fair values
of InterWest's securities held to maturity as of the dates indicated.

LOANS RECEIVABLE AND LOANS HELD FOR SALE Loans receivable increased by $203
million, or  15 percent, from $1.359 billion as of September 30, 1998, to $1.562
billion as of September 30, 1999. During the year ended September 30, 1999, the
principal balances outstanding of multi-family residential, commercial real
estate, real estate construction, consumer, commercial and agricultural loans
increased. These increases were partially offset by a decrease in single-family
residential mortgage loans outstanding as a result of loan sales during the
first half of 1999.

    The acquisitions of Central, Pacific, Pioneer, Puget and Kittitas increased
InterWest's ability to originate commercial loans. These acquisitions, as well
as the development of commercial banking at InterWest Bank, are changing the
composition of the InterWest loan portfolio to that of a financial institution
that emphasizes both real estate mortgage and commercial lending. Growth in
commercial lending should shorten duration risk, increase net interest margin,
create better protection from interest rate volatility and ultimately meet the
needs of InterWest's customers.

    Single-family residential mortgage loans outstanding decreased $179.1
million from September 30, 1998, due to loan sales and increased emphasis on
commercial lending. As of September 30, 1999, single-family residential mortgage
loans totaled $448.1 million, or 27.9 percent of total gross loans, compared to
$627.2 million, or 42.5 percent of total gross loans, as of September 30, 1998.
Due primarily to rising interest rates, loan sales have declined during the
second half of 1999. Based on the current interest rate environment, InterWest
anticipates that sales of single-family mortgage loans will remain at low levels
during 2000 relative to 1998 and the first half of 1999.

    Income property (multi-family residential and commercial real estate)
mortgage loans outstanding increased $155.9 million from September 30, 1998,
representing a growth rate of 48.6 percent. As of September 30, 1999,
outstanding income property loans totaled $476.8 million, or 29.6 percent of
total gross loans, compared to $320.9 million, or 21.8 percent of total gross
loans, as of September 30, 1998.

    Real estate construction loans, which are primarily secured by single-family
and multi-family residential properties, increased $63.7 million from
September 30, 1998, representing a growth rate of 35.0 percent. As of
September 30, 1999, real estate construction loan balances outstanding were
$245.7 million, or 15.3 percent of total gross loans, compared to $182.0
million, or 12.3 percent of total gross loans, as of September 30, 1998.

    Commercial loan balances outstanding increased $71.6 million from September
30, 1998, representing a growth rate of 32.9 percent. As of September 30, 1999,
outstanding commercial loans represented 18.0 percent of total gross loans,
compared to 14.8 percent as of September 30, 1998.

The principal lending activity of InterWest Bank is the origination of
single-family residential mortgage loans and loans secured by income
property, consumer loans, commercial loans and agricultural loans. Pacific
Northwest Bank and Kittitas Valley Bank, N.A. have loan portfolios with a
greater percentage of commercial loans than InterWest Bank.

   InterWest typically requires that mortgage loans be secured by first liens on
single-family, residential dwellings (one-to four-family units), land,
developed lots or commercial property. The purpose of the majority of real
estate mortgage loans has been for the purchase or construction of single-family
residential dwellings or refinancing of these properties, but some loans have
been for acquisition or development of residential lots or permanent loans
secured by multi-family residential and commercial properties.

SINGLE-FAMILY RESIDENTIAL MORTGAGE LOANS Prior to the acquisition of Central in
1996, the primary lending activity of InterWest was the origination of mortgage
loans to enable borrowers to refinance and purchase existing dwellings or to
construct new single-family dwellings on properties located within its primary
market area. Management believes that focusing on single-family residential
mortgage loans has been successful in contributing to interest income while
reducing overall credit and collateral risk. InterWest's single-family
residential loan portfolio also includes loans on two- to four-family dwellings
and manufactured homes.

   InterWest presently originates both fixed-rate loans and adjustable-rate
mortgage loans ("ARMs") secured by single-family residential properties with
loan terms of up to 30 years. ARMs have interest rates that adjust based upon
changes in the predetermined index for a period matching the repricing period of
the loan. Borrower demand for ARMs versus fixed-rate mortgage loans is a
function of the level of interest rates, the expectations of changes in the
level of interest rates and the difference between the interest rates and loan
fees offered for fixed-rate mortgage loans and the rates and loan fees for
ARMs.

MULTI-FAMILY RESIDENTIAL AND COMMERCIAL REAL ESTATE MORTGAGE LOANS InterWest
originates mortgage loans on commercial real estate and multi-family residential
properties with terms of up to 30 years in its primary market area. These loans
are secured by improved property such as apartment buildings, condominium
projects, office buildings, small commercial business properties, churches,
subdivision developments and strip shopping centers.

   Multi-family residential and commercial real estate mortgage loans generally
have larger balances outstanding and involve greater risks than residential
mortgage loans because payments on loans secured by income properties are
dependent on the successful operation or management of the properties. As a
result, repayment of such loans may be subject to conditions in the real estate
market or the economy to a greater extent than single-family residential real
estate loans. These loans may involve large loan balances to single borrowers or
groups of related borrowers.

REAL ESTATE CONSTRUCTION InterWest originates real estate construction loans to
residential owner-occupants (custom construction loans) and to contractors
building residential properties for resale, as well as construction loans for
condominiums, multi-family residential properties and land development on
properties located within its primary market area. Construction loans to
owner-occupants generally are converted to single-family residential mortgage
loans.

    Real estate construction loans may involve additional risks because loan
funds are collateralized by the project under construction, which is of
uncertain value prior to completion. Delays may arise from labor problems,
material shortages may be experienced and other unpredictable contingencies may
occur. It is important to evaluate accurately the total loan funds required to
complete a project and related loan-to-value ratios. Because of these factors,
the analysis of prospective construction loan projects requires an expertise
that is different in significant respects from the expertise required for real
estate mortgage lending. Construction lending is generally considered to involve
a higher degree of collateral risk than long-term financing of residential
properties. InterWest's risk of loss on a construction loan is dependent largely
upon the

<PAGE>

                                         PAGE 26
                              INTERWEST 99 AR

accuracy of the initial estimate of the property's value and marketability at
completion of construction or development and the estimated cost (including
interest) of construction. If the estimate of construction costs and the
marketability of the property upon completion of the project prove to be
inaccurate, InterWest may be required to advance additional funds to complete
development of the project.

    InterWest's underwriting criteria are designed to evaluate and minimize the
risks of each real estate construction loan. Among other things, InterWest
considers evidence of the availability of permanent financing for the borrower,
the reputation of the borrower, the amount of the borrower's equity in the
project, the independent appraisal and review of cost estimates, the
pre-construction sale and leasing information, and the cash flow projections of
the borrower.

COMMERCIAL LOANS Commercial loans include a wide range of loan types to small
and medium-sized businesses. Commercial loans include commercial lines of credit
with variable rates and maturities of one year or less. Commercial loans also
include equipment and operational loans with terms generally not exceeding five
years. These loans are primarily secured by liens on real estate, capital
assets, accounts receivable and inventory, although certain loans are unsecured.
Commercial lending has increased risks as a result of dependence on income
production for future repayment, and in certain circumstances, the lack of
tangible collateral. Commercial loans are underwritten based on the financial
strength and repayment ability of the borrower, as well as the value of any
collateral securing the loans. Commercial lending operations rely on a strong
credit culture that combines prudent credit policies and individual lender
accountability.

AGRICULTURAL LOANS Agricultural loans include seasonal production loans secured
by crops and equipment. These loans generally have adjustable rates that are
renewed annually. Agricultural loans also include loans secured by farmland.
Most agricultural real estate loans have terms of less than five years and have
variable interest rates.

CONSUMER LOANS Consumer loans consist of automobile loans, home equity loans and
loans for other consumer purposes. Consumer lending may involve special risks,
including decreases in the value of collateral and transaction costs associated
with foreclosure and repossession.

LOANS HELD FOR SALE Loans held for sale were $23.1 million as of September 30,
1999, compared to $93.1 million as of September 30, 1998. This decrease
reflects declining loan sales during the second half of 1999. Loans intended for
sale in the secondary market are carried at the lower of cost or estimated fair
value in aggregate. Net unrealized losses are recognized in a valuation
allowance by charges to income. Loans that are held for sale are generally
fixed-rate single-family mortgage loans, sub-prime loans secured by
single-family residential real estate and loans originated under a Small
Business Administration program. Loans are typically sold to FHLMC and other
financial institutions. In connection with most loan sales, InterWest retains
the right to service the loans, for which it generally receives a fee based on
the difference between the rate paid to the investor and that collected from the
borrower. InterWest capitalizes loan-servicing rights either through the
purchase or origination of mortgage loans that are subsequently sold or
securitized with the servicing rights retained. Loan servicing rights are
included in intangible assets and are amortized as an offset to service fees in
proportion to and over the period of servicing income, not to exceed 15 years.
Periodically, InterWest has sold loan servicing rights. During 1999, InterWest
sold the loan servicing rights for $530 million of single-family mortgage loans
resulting in a gain of $2.8 million.

NON-PERFORMING LOANS Loans are generally placed on non-accrual when they become
past due over 90 days or when the collection of interest or principal is
considered unlikely. InterWest does not return a loan to accrual status until it
is brought current with respect to both principal and interest and future
principal payments are no longer in doubt. When a

<PAGE>

                                         PAGE 27
                              INTERWEST 99 AR

loan is placed on non-accrual status, any previously accrued and uncollected
interest is reversed from interest income. As of September 30, 1999 and 1998,
InterWest had $10.9 million and $8.2 million, respectively, of loans on
non-accrual status.

    InterWest performs a review of its loan portfolio for weaknesses in credit
quality on an ongoing basis to identify potential problem loans. This review
process results in internal loan classifications based on risk characteristics
and loan performance. The overall objective of this review process is to
identify trends in the credit quality of the loan portfolio and to determine the
level of loss exposure to evaluate the need for an adjustment to the allowance
for losses on loans.

ALLOWANCE FOR LOSSES ON LOANS InterWest's allowance for losses on loans was
$14.1 million or 0.90 percent of loans receivable as of September 30, 1999,
compared to $13.2 million, or 0.96 percent of loans receivable as of September
30, 1998. Net loan charge-offs for 1999 were $1.1 million or 0.08 percent of the
average balance of loans outstanding during the year. Net loan charge-offs were
$0.9 million and $0.6 million in 1998 and 1997, respectively.

    The allowance for losses on loans is maintained at an amount to sufficiently
provide for estimated losses based on evaluating known and inherent risks in the
loan portfolio. Management analyzes the factors underlying the quality of the
loan portfolio. These factors include changes in the size and composition of the
loan portfolio, delinquency levels, actual loan loss experience, current
economic conditions, and detailed analysis of individual loans for which full
collectibility may not be assured. The appropriate level of the allowance for
losses on loans is estimated based upon factors and trends identified by
management.

    When available information confirms that specific loans or portions thereof
are uncollectible, these amounts are charged off against the allowance for
losses on loans. The existence of some or all of the following criteria will
generally confirm that a loss has been incurred: the loan is significantly
delinquent and the borrower has not evidenced the ability or intent to bring the
loan current; there is no recourse to the borrower, or if there is recourse, the
borrower has insufficient assets to pay the debt; the fair value of the loan
collateral is significantly below the current loan balance, and there is little
or no near-term prospect for improvement. A provision for losses on loans, which
is a charge against operations, is added to the allowance for losses on loans
based on ongoing assessments of credit risk in the loan portfolio.

    InterWest believes it has established its allowance for losses on loans in
accordance with generally accepted accounting principles. However, there can be
no assurance that in the future, regulators, when reviewing InterWest's loan
portfolio, will not request InterWest to increase its allowance for losses on
loans, thereby affecting InterWest's financial condition and results of
operations. In addition, because future events affecting borrowers and
collateral cannot be predicted with certainty, there can be no assurance that
the existing allowance for losses on loans is adequate. Substantial increases
may be necessary should the quality of the loan portfolio deteriorate as a
result of the factors discussed above.

InterWest maintains an estimated allowance for losses on loans based on the
analyses conducted by management and credit personnel. The allowance for losses
on loans is allocated to certain loan categories based on the relative risk
characteristics and actual loss experience of the loan portfolio. Management has
reviewed the allocations in the various loan categories and believes the
allowance for losses on loans was adequate at all times during the five-year
period ended September 30, 1999. Although the allocation of the allowance for
losses on loans is an important credit management tool, the entire allowance for
losses on loans is available for the entire loan portfolio.

The level of non-performing loans relative to loans receivable has increased
each year since 1994. This trend may continue as InterWest expands its
commercial lending activities and expands into new geographic and product
markets. Interest income that would have been recorded for the year ended
September 30, 1999 had non-accrual loans been current in accordance with their
original terms amounted to approximately $729,000.

DEPOSITS  InterWest offers various types of deposit accounts, including savings,
checking accounts, money market accounts and a variety of certificate of deposit
accounts. Deposit accounts vary as to terms, with the principal differences
being the minimum balance required, the time period the funds must remain on
deposit, the interest rate, and the deposit or withdrawal option. InterWest has
rarely relied on brokered deposits, but has generated deposits through a
marketing strategy that employs a sales staff responsible for establishing new
customer relationships.

    Non-interest-bearing deposits increased to $197.7 million as of September
30, 1999, from $178.6 million as of September 30, 1998. Non-interest-bearing
deposits represented 12.5 percent of total deposits as of September 30, 1999,
compared to 11.4 percent as of September 30, 1998.

    Interest-bearing transaction accounts (which includes interest-bearing
checking, money market and savings accounts) increased to $548.4 million as of
September 30, 1999, compared to $539.2 million as of September 30, 1998.
Interest-bearing transaction accounts represented 34.8 percent of total deposits
as of September 30, 1999, compared to 34.5 percent as of September 30, 1998.

    Certificates of deposit decreased to $832.8 million as of September 30,
1999, compared to $847.0 million as of September 30, 1998. Certificates of
deposit represented 52.7 percent of total deposits as of September 30, 1999, a
decrease from 54.1 percent as of September 30, 1998.

    Management is continuing to pursue initiatives to increase the percentage of
non-interest-bearing deposits and interest-bearing transaction deposits relative
to certificates of deposit. This activity should increase net interest income
and service fee revenue while building customer relationships. As of September
30, 1999, 47.3 percent of total deposits were transaction accounts, compared to
45.9 percent as of September 30, 1998.

    The following table indicates the amount of the InterWest's certificates of
deposit with balances equal to or greater than $100,000 classified by time
remaining until maturity as of September 30, 1999.

FHLB ADVANCES, SECURITIES SOLD UNDER AGREEMENT TO REPURCHASE AND OTHER
BORROWINGS InterWest borrows through advances from the Federal Home Loan Bank
(FHLB) and securities sold under agreements to repurchase with third parties.
These borrowing sources totaled $814.2 million as of September 30, 1999,
compared to $674.6 million as of September 30, 1998, and $753.6 million as of
September 30, 1997. The proceeds from these borrowings were used to fund growth
in loans receivable and securities.

    The FHLB provides credit for member financial institutions. As members,
financial institutions are required to own capital stock in the FHLB, and are
authorized to apply for advances on the security of such stock, certain home
mortgages and other assets (principally securities that are obligations of, or
guaranteed by, the United States). Advances are made to member financial
institutions pursuant to several different programs. These programs are
generally designed to meet the financial institution's needs while still
reflecting market terms and conditions. The subsidiary banks rely upon advances
from the FHLB to supplement funds available to lend and to meet liquidity
guidelines. Interest rates on these advances vary in response to general
economic conditions. The contractual maturities of InterWest's FHLB advances are
generally greater than one year; however, many of these advances have options
whereby the FHLB can call the borrowing due prior to the contractual maturity.
The amount of such advances with call options exercisable within one year was
$377 million as of September 30, 1999.

    InterWest uses the securities market for borrowings by utilizing its
securities available for sale and securities held to maturity as collateral.
These borrowings are collateralized by securities with an estimated fair value
exceeding the face value of the borrowings. Certain securities sold under
agreements to repurchase contractually due beyond 90 days have an option whereby
the creditor can call the agreement due within 90 days. The amount of such
securities sold under agreements to repurchase with call options exercisable
within 90 days was $100 million as of September 30, 1999.

borrowings by InterWest during the periods indicated:

    On January 20, 1999, the Board of Directors of InterWest Bancorp authorized
the purchase of up to 5 percent of InterWest Bancorp's outstanding shares of
common stock in the open market over a twelve-month period. During 1999,
InterWest Bancorp repurchased 521,500 shares (3.3 percent of the total common
shares outstanding) at a total price of $11.9 million. This represents an
average price of $22.84 per common share repurchased.

    InterWest's total shareholders' equity was $165.3 million as of September
30, 1999, a decrease of $6.4 million or 4 percent from $171.7 million as of
September 30, 1998.

    Book value per share decreased to $10.71 as of September 30, 1999, from
$10.97 as of September 30, 1998. Shareholders' equity as a percentage of total
assets was 6.41 percent as of September 30, 1999, compared to 7.01 percent as of
September 30, 1998.

    The decrease in shareholders' equity and book value per share was due to an
increase in the unrealized loss on securities available for sale, net of tax, of
$15.3 million, common stock repurchases of $11.9 million and dividends paid to
shareholders of $8.8 million. The increase in the unrealized loss on securities
available for sale was primarily due to rising interest rates during 1999. These
decreases in shareholders' equity were partially offset by net income of $27.9
million and proceeds received from the exercise of common stock options of $1.5
million.

    During fiscal year 1999, InterWest Bancorp, Inc. declared cash dividends
totaling $0.56 per share, an increase from $0.52 per share for fiscal year 1998.
The amount of dividends reported in the consolidated statement of shareholders'
equity for 1998 varies from $0.52 due to the application of the
pooling-of-interests method of accounting to the financial statements for the
acquisitions of Pacific, Pioneer and Puget.

    On November 15, 1999, $40 million of 9.875 percent Capital Securities were
issued by InterWest Capital Trust I (the Trust). The Trust is a business trust
organized in November 1999, and 100 percent of the common equity of the Trust is
owned by InterWest Bancorp.

    The proceeds of the offering were invested by the Trust in junior
subordinated debentures of InterWest Bancorp. The debentures held by the Trust
are the sole assets of the Trust. Distributions on the capital securities issued
by the Trust are payable semiannually at 9.875 percent per annum, which is equal
to the interest rate being earned by the Trust on the debentures held by the
Trust. The capital securities are subject to mandatory redemption, in whole or
in part, upon repayment of the debentures. The debentures will not mature
earlier than November 15, 2009, and not later than November 15, 2029. InterWest
Bancorp has entered into agreements which, taken collectively, fully and
unconditionally guarantee the capital securities subject to the terms of each of
the guarantees.

    InterWest Bancorp intends to use the net proceeds for general corporate
purposes. The capital securities will be included with borrowings as a separate
line item in the consolidated statements of financial condition and InterWest
will record distributions payable on the capital securities as interest expense
in the consolidated statements of income. The capital securities will qualify as
Tier 1 capital under the capital guidelines of the Federal Reserve Board.

    On November 16, 1999, the Board of Directors of InterWest Bancorp authorized
the purchase of an additional 5 percent of InterWest Bancorp's outstanding
shares of common stock in the open market over a twelve-month period.

LIQUIDITY RESOURCES

Liquidity management focuses on the need to meet both short-term funding
requirements and InterWest's long-term strategies and goals. Specifically, the
objective of liquidity management is to ensure the continuous availability of
funds to meet the demands of depositors, creditors and borrowers. Management
structures the balance sheet to meet these needs. InterWest desires to attract
and retain consumer and business customer relationships with a focus on
transaction accounts and commercial and consumer lending. InterWest also uses
wholesale funds through advances from the Federal Home Loan Bank (FHLB) and the
sale of securities under agreements to repurchase to fund asset growth. Other
sources of funds for liquidity include loan repayments, loan sales, security
sales and mortgage-backed and related security repayments. Repayments on loans
and mortgage-backed and related securities and deposit inflows and outflows are
affected by changes in interest rates.

    InterWest has the capacity to borrow additional funds from the FHLB through
pre-approved credit lines. These credit lines have pledge requirements whereby
InterWest must maintain unencumbered collateral with a par value at least equal
to the outstanding balance. As of September 30, 1999, the additional amount
available under credit lines from the FHLB was $232.3 million. InterWest uses
the securities market as a vehicle for borrowing by utilizing its securities
available for sale and securities held to maturity as collateral. These
borrowings are collateralized by securities with an estimated fair value
exceeding the face value of the borrowings. If the estimated fair value of the
securities were to decline as a result of an increase in interest rates or other
factors, InterWest would be required to pledge additional securities or cash as
collateral. As of September 30, 1999, InterWest had $277 million of available
credit from third parties to sell securities under agreements to repurchase.

    The analysis of liquidity also includes a review of InterWest's consolidated
statement of cash flows for 1999. The consolidated statement of cash flows
details InterWest's operating, investing and financing activities during the
fiscal year. The most significant item under operating activities was net income
of $27.9 million. Investing activities included proceeds from the sale of
securities available for sale of $258.5 million, security maturities totaling
$420.6 million and purchases of securities available for sale of $923.9 million.
Investing activities also include a $592.5 million increase in loans receivable
and $419.1 million of proceeds from the sale of loans. During 1999, financing
activities included $135.9 million in borrowing proceeds, net of borrowing
repayments, a $28.4 million increase in deposits, a $14.3 million decrease in
certificates of deposit and a total of $8.8 million paid in cash dividends to
shareholders.

    The enforcement powers available to banking regulators are substantial and
include, among other things, the ability to assess civil monetary penalties, to
issue cease-and-desist or removal orders and to initiate injunctive actions
against banking organizations and institution-affiliated parties, as defined. In
general, enforcement actions must be initiated for violations of laws and
regulations and unsafe or unsound practices. Other actions, or inactions, may
provide the basis for enforcement action, including misleading or untimely
reports filed with regulatory authorities. Applicable law also requires public
disclosure of final enforcement actions.


YEAR 2000 READINESS DISCLOSURES

InterWest has undertaken efforts to address the Year 2000 computer problem. Many
computer programs were not able to recognize the year 2000, since most programs
and systems were designed to store calendar years in the 1900s by assuming the
"19" and storing only the last two digits of the year. The problem is especially
important to financial institutions since many transactions, such as interest
accruals and payments, are date sensitive, and because InterWest interacts with
numerous customers, vendors and third party service providers who must also
address the Year 2000 issue. The problem is not limited to computer systems.
Year 2000 issues will potentially affect every system that has an embedded
microchip, such as automated teller machines, elevators and vaults. If not
properly addressed, the century date change could potentially cause the
production of erroneous data, miscalculations, system failures and other
operational problems.

INTERWEST'S STATE OF READINESS InterWest has been and will continue to be
committed to addressing Year 2000 issues in a prompt and responsible manner, and
has dedicated the resources to do so. Management has completed an assessment of
its automated systems and has implemented a program consistent with applicable
regulatory guidelines, to complete all steps necessary to resolve identified
issues. InterWest's process has included several phases, including project
management, assessment, testing, remediation, implementation and contingency
planning and testing of contingency plans. InterWest has determined that systems
are compliant with or has taken steps necessary to make them compliant.
Management believes that it has an effective program in place to resolve Year
2000 issues in a timely manner.

PROJECT MANAGEMENT Each subsidiary bank has implemented a process to address
Year 2000 issues. This process includes a project manager, senior management and
departmental representatives. There have been periodic meetings with senior
management of each subsidiary bank to discuss the process, assign tasks,
determine priorities and monitor progress. Outside specialists have been
utilized when necessary. Periodic reports of testing results and progress have
been provided to each subsidiary bank's Board of Directors on the status of the
Year 2000 project. Additionally, the subsidiary banks have regularly reported to
InterWest Bancorp management and to the InterWest Bancorp Board of Directors.

ASSESSMENT InterWest's computer systems and applications were identified and
assessed to prioritize testing, remediation and contingency planning.
InterWest's primary software vendors were also assessed during this phase, and
vendors who provide support for mission-critical systems were identified and the
majority of testing was completed as planned on mission-critical systems by
December 31, 1998. Additionally, InterWest has worked with significant borrowers
to assess the extent to which they may be affected by Year 2000 issues.

TESTING Updating and testing of InterWest's mission-critical systems and
secondary systems has been completed. Based on the results of testing, InterWest
identified internal computer systems that were non-compliant. As discussed
below, efforts to remediate and implement renovated system applications has been
completed for mission-critical and secondary systems.

REMEDIATION AND IMPLEMENTATION This phase involved obtaining and implementing
renovated system applications provided by InterWest's vendors. As renovated
systems or new applications were received and implemented, InterWest tested them
for Year 2000 compliance. As of June 30, 1999, updating for mission-critical
systems was completed. This phase continued throughout the remainder of 1999 for
some secondary systems.

                              INTERWEST 99 AR

CONTINGENCY PLANNING AND TESTING OF CONTINGENCY PLANS InterWest has developed
contingency plans related to processes and systems that could be impacted by
Year 2000 issues. During the second half of 1999 contingency plans were tested.
Based on management's assessments of the readiness of vendors, service providers
and substantial borrowers, InterWest modified contingency plans as necessary or
developed additional contingency plans. The review and testing of contingency
plans has been an ongoing process subjected to internal assessments, third party
and regulatory review. Additionally, specific timeframes were established for
the monitoring, assessment and testing of contingency planning as well as
"trigger" dates for implementing contingency plans. Certain circumstances as
described in "Risks Related to Year 2000 Issues" may occur for which there are
no completely satisfactory contingency plans.

ESTIMATED COSTS TO ADDRESS INTERWEST'S YEAR 2000 ISSUES Based on costs incurred
to date, expenses and required capital expenditures related to meeting Year 2000
issues have not had a material effect on the operations or financial condition
of InterWest. Many systems have been tested and any remediation necessary
performed by the already existing information systems staff. InterWest has been
and will continue to expense any costs associated with Year 2000 issues from
operations as incurred. Year 2000 challenges facing vendors of mission-critical
software and systems, third-party service providers, and customers, could have a
material effect on the operations or financial condition of InterWest, to the
extent such parties are materially affected by such challenges.

RISKS RELATED TO YEAR 2000 ISSUES The Year 2000 poses certain risks to InterWest
and its operations. Some of these risks are present because InterWest purchases
technology and information systems applications from other parties who face Year
2000 issues and relies on third party service providers for processing data. In
addition, other risks are inherent in banking or are risks faced by many
companies. Although it is impossible to identify all potential risks that
InterWest may face moving into the millennium, management has identified the
following significant potential risks.

    Banks may experience a contraction in their deposit base if a significant
amount of deposited funds are withdrawn by customers prior to the Year 2000, and
interest rates may increase as the millennium approaches. This potential deposit
contraction could make it necessary for InterWest to change its sources of
funding and could affect future earnings. InterWest has established a
contingency plan for addressing this situation, should it arise, in its asset
and liability management policies. The plan includes maintaining the ability to
borrow funds from correspondent banks and the FHLB. Significant demand for funds
from other banks could reduce the amount of funds available for InterWest to
borrow. If insufficient funds are available from these sources, InterWest may
also sell investment securities or other liquid assets to meet liquidity needs.

    InterWest originates loans to individuals and businesses in its marketing
area. If these customers are adversely affected by Year 2000 issues, their
ability to repay loans could be impaired. This increased credit risk could
adversely affect InterWest's financial performance. During the assessment phase
of InterWest's Year 2000 program, InterWest identified substantial borrowers,
and has worked with such borrowers to ascertain their levels of exposure to Year
2000 issues. To the extent that InterWest is unable to assure itself of the Year
2000 readiness of such borrowers, it intends to apply additional risk assessment
criteria to the indebtedness of such borrowers and make any necessary related
adjustments to InterWest's allowance for losses on loans.

    InterWest's operations, like those of many other companies, can be adversely
affected by the Year 2000 failures of other companies upon whom InterWest
depends for the functioning of its automated systems. Accordingly, InterWest's
operations could be materially affected if the operations of mission-critical
third party service providers are adversely affected. As described previously,
InterWest has identified its mission-critical vendors and has monitored their
Year 2000 compliance programs.

    Based on InterWest's Year 2000 efforts, management presently believes the
Year 2000 will not result in significant operational problems. However, the Year
2000 efforts of third parties are not within InterWest's control, and their
failure to address Year 2000 issues could result in, among other things,
business disruption, operational problems, material adverse impact on earnings,
increased credit risk and legal liability for InterWest. While InterWest has
developed contingency plans to address temporary issues and disruptions caused
by the Year 2000, given the unprecedented nature of the Year 2000 computer
problem, there can be no assurance that Year 2000 issues will not arise, or that
any issues will be fully mitigated.

FORWARD-LOOKING STATEMENTS The disclosures related to Year 2000 issues include
certain "forward-looking statements" concerning the future operations of
InterWest. It is InterWest's desire to take advantage of the "safe harbor"
provisions of the Private Securities Litigation Reform Act of 1995. This
statement is for the express purpose of availing InterWest of the protections of
such safe harbor with respect to all forward-looking statements contained in
Year 2000 disclosures. InterWest's ability to predict results or the effect of
future plans and events is inherently uncertain, and is subject to factors that
may cause actual results to differ materially from those projected. Factors that
could affect the actual results include the possibility that systems
modifications will not operate as intended, the possibility of unexpected costs,
and the uncertainty associated with the impact of the century change on
InterWest's customers, vendors and third party service providers. These factors
should be considered in evaluating the forward-looking statements and undue
reliance should not be placed on such statements.

MARKET RISK

InterWest's results of operations are largely dependent upon its ability to
manage interest rate risk. Management considers interest rate risk to be a
significant market risk that could have a material effect on InterWest's
financial condition and results of operations. InterWest does not currently use
derivatives to manage market and interest rate risks.

    InterWest is sensitive to the potential change in interest rates and the
resulting impact on net interest income. It has been an objective of management
to reduce this sensitivity through the origination of adjustable rate loans,
balloon mortgages, and short-term commercial and consumer loans. This enables
InterWest to better match the duration of its deposit base with these types of
assets.

    In addition to adjustable rate loans, InterWest uses a number of other
strategies to minimize the impact on net income due to significant changes in
interest rates. The strategies utilized by InterWest include sales of long-term,
fixed-rate mortgage loans, growth in non-interest-bearing deposits, purchases of
adjustable rate and callable agency securities, and short-term commercial
lending.

    The table on the following page sets forth the balances of InterWest's
financial instruments at the expected maturity dates, as well as the estimated
fair value of those financial instruments as of September 30, 1999. The expected
maturities take into consideration estimated principal prepayments for loans and
mortgage-backed securities. Principal prepayments are the amounts of principal
reduction, over and above normal amortization.

    The expected maturities for financial liabilities with no stated maturity
reflect assumptions based on estimated future roll-off rates. The roll-off rates
for non-interest-bearing deposits, interest-bearing checking accounts, money
market accounts and savings accounts are 14 percent, 20 percent, 33 percent and
20 percent, respectively. The weighted average interest rates for financial
instruments presented are actual as of September 30, 1999.

    The estimated fair value amounts have been determined by InterWest using
available market information and appropriate valuation methodologies. However,
considerable judgment is necessary to interpret market data in the development
of the estimated fair value amounts. Accordingly, the estimated fair values
presented herein are not necessarily indicative of the amounts InterWest could
realize in a current market exchange. The use of different market assumptions
and/or estimation methodologies may have a material effect on the estimated fair
value amounts. The carrying value of cash and cash equivalents, federal funds
sold and accrued interest receivable is a reasonable estimate of the fair value
for such financial assets. The estimated fair values of securities available for
sale, securities held to maturity and loans held for sale are based on quoted
market rates and dealer quotes. The estimated fair value of loans receivable is
based on discounted future cash flows, using interest rates currently offered
for loans of similar characteristics. FHLB stock does not have a market and the
estimated fair value is unknown. As such, the carrying value is a reasonable
estimate of the fair value. The estimated fair value of deposits with no stated
maturity, such as checking accounts, money market accounts and savings accounts,
is equal to the amount payable on demand as of September 30, 1999. The estimated
fair value of certificates of

deposit is based on the present value of contractual cash flows using a discount
rate based on the current average rate for deposits of like maturities. The
estimated fair value of FHLB advances and securities sold under agreements to
repurchase is based on the present value of future cash flows using a discount
rate equal to the rate offered on similar borrowings with similar maturities as
of September 30, 1999. The estimated fair values presented are based on
information available as of September 30, 1999.

</TABLE>

While this table provides some information about InterWest's interest
sensitivity, it does not predict the trends of future earnings. For this reason,
InterWest uses financial modeling to forecast earnings under different interest
rate projections. While this modeling is helpful in managing interest rate risk,
it does require significant assumptions for the projection  of loan prepayment
rates, loan origination volumes and liability funding sources that may prove to
be inaccurate.

FORWARD-LOOKING STATEMENTS In this Annual Report to Shareholders, InterWest has
included certain "forward-looking statements" concerning its future operations.
It is InterWest's desire to take advantage of the "safe harbor" provisions of
the Private Securities Litigation Reform Act of 1995. This statement is for the
express purpose of availing InterWest of the protections of such safe harbor
with respect to all forward-looking statements contained in this Annual Report
to Shareholders. Sentences containing words such as "may," "will," "expect,"
"anticipate," "believe," "estimate," "should," "projected," or similar words may
constitute forward-looking statements. Although InterWest believes that the
expectations expressed in these forward-looking statements are based on
reasonable assumptions within the bounds of its knowledge of its business and
operations, it is possible that actual results may differ materially from these
expectations. InterWest has used these statements to describe expectations and
estimates in various areas, including changes in the economy of the markets in
which it operates; interest rate movements; Year 2000 issues; data conversions
for acquired institutions; the impact of competitive products, services and
pricing; and legislative, regulatory and accounting changes affecting the
banking and financial services industry. Actual results could vary materially
from the future results covered in forward-looking statements. Factors such as
Year 2000 issues, interest rate trends and loan delinquency rates, as well as
the general state of the economy in Washington state and the United States as a
whole, could also cause actual results to vary materially from the future
results anticipated in such forward-looking statements. These factors should be
considered in evaluating the forward-looking statements and undue reliance
should not be placed on such statements.

REPORT OF MANAGEMENT TO SHAREHOLDERS

    Management of InterWest Bancorp, Inc. is responsible for the preparation,
integrity and fair presentation of its published financial statements. The
consolidated financial statements included in this annual report have been
prepared in accordance with generally accepted accounting principles and, as
such, include judgments and estimates of management. InterWest Bancorp, Inc.
also prepared the other information included in the annual report and is
responsible for its accuracy and consistency with the consolidated financial
statements.

    Management is responsible for establishing and maintaining an effective
internal control structure over financial reporting. The internal control system
is supported by written policies and procedures and by audits performed by an
internal audit staff that reports to the Audit Committee of the Board of
Directors. Internal auditors monitor the operation of the internal control
system and report findings to management and the Audit Committee, and corrective
actions are taken to address identified control deficiencies and other
opportunities for improving the system. The Audit Committee, composed solely of
outside directors, provides oversight to the financial reporting process. There
are inherent limitations in the effectiveness of any system of internal control,
including the possibility of human error and circumvention or overriding of
controls. Accordingly, even an effective internal control system can provide
only reasonable assurance with respect to financial statement preparation. The
concept of reasonable assurance is based on the recognition that the costs of
such a system should not exceed the benefits to be received. Management believes
the system provides an appropriate cost/benefit balance.

    Management assesses InterWest Bancorp, Inc.'s internal control structure
over financial reporting. Based on these assessments, management believes that
InterWest Bancorp, Inc. maintains an effective internal control system over
financial reporting.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

Board of Directors
InterWest Bancorp, Inc.

    We have audited the accompanying consolidated statements of financial
condition of InterWest Bancorp, Inc., and subsidiaries as of September 30, 1999
and 1998, and the related consolidated statements of income, shareholders'
equity, and cash flows for each of the three years in the period ended September
30, 1999. These consolidated financial statements are the responsibility of
InterWest's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
InterWest Bancorp, Inc., and subsidiaries at September 30, 1999 and 1998, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended September 30, 1999, in conformity with
generally accepted accounting principles.

    As described in Note 2 to the consolidated financial statements, InterWest
Bancorp, Inc. adopted certain new accounting standards in fiscal years 1999 and
1998 as required by the Financial Accounting Standards Board.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



NOTE 1
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION The consolidated financial statements include the
accounts of InterWest Bancorp, Inc. (InterWest Bancorp), and its wholly owned
subsidiaries (collectively, InterWest). As of September 30, 1999, InterWest
Bancorp's wholly owned subsidiaries were InterWest Bank, Pacific Northwest
Bank and Kittitas Valley Bank, N.A. All material intercompany transactions
and balances have been eliminated in consolidation.

    On January 15, 1998, InterWest Bancorp acquired Puget Sound Bancorp, Inc.
(Puget) of Port Orchard, Washington, and its commercial banking subsidiary,
First National Bank of Port Orchard. On June 15, 1998, InterWest Bancorp
acquired Pacific Northwest Bank (Pacific) of Seattle, Washington. On June 16,
1998, InterWest Bancorp acquired Pioneer Bancorp, Inc. (Pioneer) of Yakima,
Washington, and its commercial banking subsidiary, Pioneer National Bank.
These transactions have been accounted for using the pooling-of-interests
method. Accordingly, InterWest's consolidated financial statements have been
restated to include the accounts and operations of Puget, Pacific and Pioneer
as if the companies were combined for all periods presented.

    On August 31, 1998, InterWest Bancorp completed the acquisition of
Kittitas Valley Bancorp, Inc. (Kittitas) and its commercial banking
subsidiary, Kittitas Valley Bank, N.A. of Ellensburg, Washington. This
acquisition has been accounted for using the purchase method.

    On October 15, 1998, First National Bank of Port Orchard was merged into
Pacific. On January 22, 1999, Pioneer National Bank was merged into Pacific.

USE OF ESTIMATES The preparation of the financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect amounts reported in the consolidated
financial statements. Changes in these estimates and assumptions are
considered reasonably possible and  may have a material impact on the
financial statements and thus actual results could differ from the amounts
reported and disclosed herein.

NATURE OF BUSINESS InterWest Bancorp is a multi-bank holding company
incorporated in Washington state. Through its subsidiaries, a wide range of
financial services are offered to individuals and businesses throughout
western and central Washington state. Financial services of InterWest include
the banking activities of accepting deposits from individuals and businesses
and originating residential loans, consumer loans, commercial real estate
loans, commercial loans and agricultural loans.

    Investment products are available through InterWest Financial Services,
Inc. and insurance products are available through InterWest Insurance Agency,
Inc., wholly owned subsidiaries of InterWest Bank.

CASH AND CASH EQUIVALENTS For purposes of the consolidated statements of cash
flows, InterWest considers all deposits and securities with an original term
to maturity of three months or less to be cash equivalents.

SECURITIES AVAILABLE FOR SALE AND SECURITIES HELD TO MATURITY Those
securities that InterWest has the positive intent and ability to hold to
maturity are classified as held to maturity and are carried at amortized
cost. Securities are adjusted to the lower of cost or estimated fair value
only when an other than temporary impairment in value occurs.

    Those securities that are not classified as held to maturity are
classified as available for sale, and are carried at estimated fair value
with unrealized gains and losses excluded from net income and are reported,
net of tax, as accumulated other comprehensive income or loss, a component of
shareholders' equity. The basis of securities subsequently sold is determined
by the specific identification method.

<PAGE>

                                                PAGE 46
                                 INTERWEST 99 AR




    The carrying value of securities held to maturity and securities
available for sale is adjusted for unamortized discounts and premiums.
Discounts are accreted and premiums are amortized using the effective yield
method to maturity of the securities. Such accretion and amortization is
included as interest income on securities.

LOANS RECEIVABLE Loans receivable are stated at the principal amount
outstanding, net of deferred loan fees, discounts and the allowance for
losses on loans. InterWest typically requires that mortgage loans be secured
by first liens on single-family dwellings, land, developed lots or commercial
property. Commercial loans can also be secured by capital assets, accounts
receivable and inventory, although certain loans are unsecured. Agricultural
loans are generally secured by farmland, crops and/or equipment.

LOANS HELD FOR SALE Loans intended for sale in the secondary market are
recorded at the lower of cost or estimated fair value in aggregate. Net
unrealized losses are recognized in a valuation allowance by charges to
income.

LOAN FEE INCOME, INTEREST INCOME ON LOANS RECEIVABLE AND UNEARNED INTEREST
Loan origination fees and direct costs related to loan origination activities
are deferred and amortized into interest income over contractual or actual
loan lives as an adjustment to the loan yield. Deferred fees and costs
related to loans sold are recognized into income at the time the loans are
sold.

    Interest is accrued on loans receivable until the loan is 90 days
delinquent or management doubts the collectibility of the loan or the unpaid
interest, at which time InterWest establishes a reserve for any accrued
interest. If management determines the ultimate collectibility of principal
is in doubt, cash receipts on non-accrual loans are applied to reduce the
principal balance.

ALLOWANCE FOR LOSSES ON LOANS The allowance for losses on loans is maintained
at a level sufficient to provide for estimated losses based on evaluating
known and inherent risks in the loan portfolio and upon management's
continuing analysis of the factors underlying the quality of the loan
portfolio. These factors include changes in the size and composition of the
loan portfolio, actual loan loss experience, current economic conditions, and
detailed analysis of individual loans for which full collectibility may not
be assured. The appropriate reserve level is estimated based upon factors and
trends identified by management at the time financial statements are prepared.

    When available information confirms that specific loans or portions
thereof are uncollectible, these amounts are charged off against the
allowance for losses on loans. The existence of some or all of the following
criteria will generally confirm that a loss has been incurred: the loan is
significantly delinquent and the borrower has not evidenced the ability or
intent to bring the loan current; InterWest has no recourse to the borrower,
or if it does, the borrower has insufficient assets to pay the debt; the
estimated fair value of the loan collateral is significantly below the
current loan balance, and there is little or no near-term prospect for
improvement.

    All loans are periodically evaluated for impairment, except large groups
of smaller-balance homogenous loans that are collectively evaluated for
impairment, and loans that are measured at estimated fair value or at the
lower of cost or estimated fair value. InterWest considers all single-family
residential (including construction), consumer loans and certain commercial
loans to be smaller-balance homogenous loans. A loan is impaired when it is
probable that a creditor will be unable to collect all amounts due according
to the contractual terms of the loan agreement. The valuation of impaired
loans is based on the present value of expected future cash flows discounted
at the loans effective interest rate or, as a practical expedient, at the
loan's observable market price, or the estimated fair value of the collateral
if the loan is collateral dependent. Generally, InterWest evaluates a loan
for impairment when it is placed on non-accrual status or if a loan is
internally risk rated as substandard or doubtful.

    A provision for losses on loans, which is a charge against income, is
added to the allowance for losses on loans based on quarterly assessments of
the loan portfolio. While management has attributed the allowance for losses
on loans to various loan portfolio segments, the allowance is general in
nature and is available for the loan portfolio in its entirety.

    The ultimate recovery of all loans is susceptible to future market
factors beyond InterWest's control. These factors may result in losses or
recoveries differing significantly from those provided in the financial
statements.

REAL ESTATE HELD FOR SALE AND REAL ESTATE HELD FOR DEVELOPMENT Real estate
held for sale and real estate held for development (collectively, real
estate) includes properties acquired through foreclosure and property
acquired with the intention of development. These properties are initially
recorded at the lower of cost or estimated fair value and are subsequently
evaluated to determine that the carrying value does not exceed the estimated
fair value of the property. Losses identified as a result of ongoing periodic
valuation of these properties are charged to operations in the period in
which they are identified and are included in loss from real estate
write-downs and operations in the consolidated statements of income.

PREMISES AND EQUIPMENT Premises and equipment are stated at cost less
accumulated depreciation. Depreciation expense is computed on the
straight-line method over estimated useful lives of up to forty years for
bank buildings and three to twenty years for furniture and equipment.

INTANGIBLE ASSETS Intangible assets arising from acquisitions represent the
excess of the purchase price over estimated fair value of net assets
acquired. InterWest periodically evaluates these intangible assets for
impairment.

    Loan servicing rights are capitalized when acquired either through the
purchase or origination of loans that are subsequently sold or securitized
with the servicing rights retained. InterWest evaluates loan servicing rights
for impairment based on the estimated fair value of those rights on a
periodic basis, using a valuation model which incorporates estimated future
servicing income, discount rates, prepayment speeds and default rates. Loan
servicing rights are included in intangible assets and are amortized as an
offset to services fees in proportion to and over the period of estimated net
servicing income.

    Intangible assets are amortized using straight-line and accelerated
methods over periods not exceeding twenty years. The level of intangible
assets as of September 30, 1999, was supported by the estimated fair value
attributed to the operations acquired and loan servicing rights retained.

INCOME TAXES InterWest accounts for income taxes using the liability method.
Under the liability method, a deferred tax asset or liability is determined
based on the enacted tax rates which will be in effect when the differences
between the financial statement carrying amounts and tax basis of existing
assets and liabilities are expected to be reported in InterWest's income tax
returns. The deferred tax expense for the year is equal to the net change in
the deferred tax asset and liability accounts from the beginning to the end
of the fiscal year. The effect on deferred taxes of a change in tax rates is
recognized in income in the period that includes the enactment date.

NET INCOME PER SHARE Basic net income per share is calculated by dividing net
income by the weighted average number of common shares outstanding during the
year. Diluted net income per share is calculated by dividing net income by
diluted weighted average shares outstanding, which includes common stock
equivalent shares outstanding using the treasury stock method. Common stock
equivalents include shares issuable upon exercise of stock options.
Unallocated shares relating to the debt-leveraged money purchase employee
stock ownership plan debt obligation are deducted in the calculation of the
weighted average shares outstanding.

STOCK OPTIONS InterWest has adopted the disclosure only provisions of
Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-based Compensation." Accordingly, employee stock options are accounted
for under Accounting Principle Board Opinion (APB) No. 25, "Accounting for
Stock Issued to Employees." Stock options are granted at exercise prices not
less than the fair value of common stock on the date of grant. Under APB No.
25, no compensation expense is recognized pursuant to InterWest's stock
option plans.

RECLASSIFICATIONS Certain reclassifications have been made to the 1998 and
1997 consolidated financial statements to conform to 1999 presentation. The
effects of the reclassifications are not considered material.

NOTE 2
ACCOUNTING CHANGES

On October 1, 1998, InterWest adopted SFAS No. 130, "Reporting Comprehensive
Income." This statement establishes standards for reporting and disclosure of
comprehensive income and its components. Comprehensive income includes net
income and other comprehensive income, which refers to unrealized gains and
losses that under generally accepted accounting principles are excluded from
net income. The adoption of this statement did not have a material impact on
InterWest's financial condition or results of operations. However, this
statement requires the classification of items of other comprehensive income
in the consolidated statements of shareholders' equity and the disclosure of
other comprehensive income as a separate component of shareholders' equity in
the consolidated statements of financial condition. All prior period amounts
have been restated to conform to this statement.

    On October 1, 1998, InterWest adopted SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." This statement
establishes standards and requirements for public enterprises regarding
information about operating segments in annual financial statements. This
statement also establishes standards for related disclosures about products
and services, geographic areas and major customers. Operating segments are
components of an enterprise that are evaluated regularly by the chief
executive officer in deciding how to allocate resources and in assessing
performance. The statement requires the disclosure of net income or net loss,
certain specific income and expense items, and assets of all operating
segments, with reconciliations to amounts presented in the consolidated
financial statements. The adoption of this statement did not have an impact
on InterWest's financial condition or results of operations. However, this
statement has affected the disclosures in InterWest's consolidated financial
statements.

    On October 1, 1998, InterWest adopted SFAS No. 134, "Accounting for
Mortgage-Backed Securities Retained After Securitization of Mortgage Loans
Held for Sale by a Mortgage Banking Enterprise," which amends SFAS No. 65,
"Accounting for Certain Mortgage Banking Activities." SFAS No. 65 previously
required that after the securitization of a mortgage loan held for sale,
InterWest classify the resulting mortgage-backed security as a trading
security. SFAS No. 134 now allows InterWest to classify the resulting
mortgage-backed securities or other retained interests based on its ability
and intent to sell or hold those securities. The adoption of this statement
did not materially affect InterWest's financial condition or results of
operations.

    In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." This
statement establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments imbedded in other
contracts, and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
condition and measure those instruments at estimated fair value. In certain
defined conditions, a derivative may be specifically designated as a hedge
for a particular exposure. The accounting for derivatives depends on the
intended use of the derivatives and the resulting hedge designation. In June
1999, the FASB issued SFAS No. 137, which effectively delayed the
implementation of SFAS No.133 for a one-year period. This statement will be
adopted by InterWest during fiscal year 2001. Management does not expect the
adoption of this statement to have a material impact on InterWest's financial
condition or results of operations.

NOTE 3
BUSINESS COMBINATIONS

    On January 15, 1998, InterWest Bancorp acquired Puget Sound Bancorp, Inc.
(Puget) of Port Orchard, Washington, the holding company of First National
Bank of Port Orchard. Under the terms of this transaction, Puget merged into

using the pooling-of-interests method. In accordance with generally accepted
accounting principles, prior period financial statements have been restated
as if the companies had been combined for all periods presented.

    The consolidated financial statements have been adjusted to conform the
December 31 fiscal year end of Puget, Pacific and Pioneer to that of
InterWest's September 30 fiscal year end. In accordance with generally
accepted accounting principles, interest income of $7,185,000, net interest
income of $4,535,000 and net income of $1,249,000 for the period from October
1, 1997, to December 31, 1997, has been included in the consolidated
statements of income for both of the years ended September 30, 1998 and 1997.
Accordingly, $1,249,000 has been deducted from retained earnings in the

    On August 31, 1998, InterWest Bancorp acquired Kittitas Valley Bancorp,
Inc. (Kittitas) and its commercial banking subsidiary, Kittitas Valley Bank,

of $27,945,000, total deposits of $39,239,000 and shareholders' equity of
$4,290,000. The transaction was completed through the payment of $6,436,000
in cash and the issuance of 229,831 shares of InterWest Bancorp common stock
to Kittitas shareholders. The shares issued to Kittitas shareholders were
purchased by InterWest Bancorp in the open market. The total acquisition
price was $12,284,000 and resulted in goodwill of $8,341,000 recorded by
InterWest Bancorp. This goodwill is being amortized using the straight-line
method over a period of twenty years. This acquisition has been accounted for
using the purchase method and as such the operations of Kittitas Valley Bank,
N.A. have been included in the consolidated financial statements for the
period subsequent to August 31, 1998. An application has been filed to merge
Kittitas Valley Bank, N.A. into Pacific Northwest Bank. It is anticipated

total loans receivable of $127,509,000, total deposits of $166,268,000 and
shareholders' equity of $20,224,000. The transaction is structured such that
shareholders of Liberty will receive eleven shares of InterWest Bancorp
common stock for each share of Liberty common stock if the average price of
InterWest Bancorp common stock is more than $21 per share for a short period
prior to closing. If the average price of InterWest Bancorp common stock for
a short period before closing is between $20 and $21 per share, the
shareholders of Liberty will receive shares of InterWest common stock with a
value of $231 for each share of Liberty common stock. If the average price of
InterWest Bancorp common stock for a short period before closing is less than
$20 per share, InterWest Bancorp has the option of adjusting the exchange
ratio such that Liberty shareholders will receive shares of InterWest Bancorp
common stock with an equivalent value of $231 for each share of Liberty
common stock or terminating the definitive agreement. It is

anticipated that the acquisition will be completed during the spring of 2000,

issued was 677,109. The transaction resulted in goodwill of approximately
$9,700,000 recorded by InterWest Bancorp. This goodwill will be amortized
using the straight-line method over a period of twenty years. This
acquisition has been accounted for using the purchase method and as such the
accounts and operations of NBT and National Bank of Tukwila have not been
included in the September 30, 1999 consolidated financial statements.

future prepayment rates.

generate taxable income in future periods. InterWest has evaluated available
evidence supporting the realization of its deferred tax assets and determined
it is more likely than not that deferred tax assets will be realized.

EMPLOYEE BENEFITS

RETIREMENT AND SAVINGS PLANS InterWest has a debt-leveraged money purchase
employee stock ownership plan (ESOP) for employees. The ESOP is a
non-contributory stock ownership plan. InterWest makes monthly contributions
to the plan of 5 percent of qualified participants' compensation.

                        INTERWEST 99 AR

    During 1998, the ESOP entered into a line of credit agreement with an
unrelated third party to borrow up to a total of $4,000,000 for the purpose
of acquiring InterWest Bancorp common stock. Interest on the line of credit
is computed at one-month LIBOR plus 1.8125 percent. Interest paid was
$284,000, $104,000, and $8,000 for the years ended September 30, 1999, 1998,
and 1997, respectively. The obligation is reduced, and shareholders' equity
increased, by the amount of any principal reduction on the line of credit by
the ESOP. During the year ended September 30, 1999, the ESOP made principal
repayments of $327,000 on the ESOP line of credit. Dividends paid on
unallocated shares of stock may be used to make payments on the line of
credit. Accordingly, $85,000, $31,000, and $35,000 of dividends were applied
toward loan payments during the years ended September 30, 1999, 1998, and
1997, respectively. The compensation of the leveraged shares is calculated by
taking the difference between the average fair value of the shares released
and the cost of the shares. Shares are released as the loan payments are made
on the ESOP line of credit. Leveraged ESOP shares during the years ended
September 30 were as follows:

    InterWest has a salary deferral 401(k) plan that is a defined
contribution plan. Employees can contribute to their deferred contribution
accounts on a pre-tax basis the maximum limit under the law. InterWest
matches a portion of the salary deferred by each participant according to the
schedule in the plan. Expenses of the ESOP and 401(k) plan were $1,575,000,
$1,302,000, and $1,042,000 for the years ended September 30, 1999, 1998 and
1997, respectively.

    InterWest also maintains several unfunded, non-qualified deferred
compensation programs for certain executive officers.

STOCK OPTION PLANS   During January 1993, the shareholders of InterWest
approved the addition of a qualified employee stock option plan (1993
incentive plan) and a non-qualified director stock option plan (1993
non-incentive plan). The awarding of stock options to certain employees of
InterWest is at the discretion of the Board of Directors. The term of the
options granted is generally five or ten years. Substantially all of the
options granted under the employees' stock option plan vest over a three to
five-year period. Under the 1993 non-incentive plan, each director was
granted 2,875 options with a term of ten years. These options were 100
percent vested at the date of the grant. This plan expired during 1997.

    In January 1997, the shareholders of InterWest approved the non-qualified
1996 Outside Directors Stock Options-For-Fees Plan (1996 Director Plan).
Under the 1996 Director Plan, non-employee directors may elect to receive
stock options in lieu of fees otherwise due for board services and may
exercise those options after one year. Each option granted under the 1996
Director Plan has a five-year term.

    InterWest had a qualified stock option plan prior to 1993 that provided
for the awarding of stock options to certain officers and employees of
InterWest at the discretion of the Board of Directors. The term of the stock
options granted ranged from four to ten years from the date of grant. This
plan expired during 1993; however, there are exercisable options outstanding
under the plan as of September 30, 1999.

    Central, Puget, Pacific, Pioneer and Kittitas had stock option plans that
have been assumed by InterWest. The number of shares and exercise prices have
been appropriately adjusted to reflect the common stock exchange ratios for each
acquisition. All outstanding Central, Puget, Pacific, Pioneer and Kittitas stock
options became 100 percent vested and exercisable upon the consummation of the
respective acquisitions. No further awards will be granted under any of these
plans.

    The exercise price of options granted under most of these plans was equal
to the fair value of the common stock on the date of the grant. Average
exercise price per share, number of shares authorized, available for grant,
granted, exercised, outstanding and currently exercisable reflect adjustments
for common stock splits.

</TABLE>

As of September 30, 1999, there were a total of 1,711,833 shares authorized
under all stock option plans and a total of 335,102 shares available for future
stock option grants.


    SFAS No. 123, "Accounting for Stock-based Compensation," requires the
disclosure of pro forma net income and net income per share had InterWest
adopted the fair value method. Under this statement, the fair value of
stock-based awards is calculated through the use of option pricing models.
These models require the use of subjective assumptions, including stock price
volatility, dividend yield, risk-free interest rate and expected time to
exercise. The fair value of options granted under stock option plans is
estimated on the date of grant using the Black-Scholes option-pricing model.
Using the assumptions below, the weighted average estimated fair value of
options granted was $7.06 in 1999, $8.04 in 1998 and $5.21 in 1997.

the weighted average estimated fair value of stock options for the year ended

</TABLE>

The compensation expense included in the pro forma net income and net income per
share is not likely to be representative of the effect on reported net income
for future years because stock options vest over several years and additional
option grants generally are made each year.

NOTE 18
REGULATORY CAPITAL

InterWest Bancorp and its banking subsidiaries are subject to risk-based capital
guidelines requiring minimum capital levels based on the credit risk of assets.
Failure to meet minimum capital requirements can initiate certain mandatory, and
possibly additional discretionary, actions by regulators that, if undertaken,
could have a material effect on InterWest's financial statements. Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
InterWest Bancorp and its banking subsidiaries must meet specific capital
guidelines that involve quantitative measures of assets, liabilities and
certain off-balance-sheet items as calculated under regulatory accounting
practices. Capital classifications are also subject to qualitative judgments by
the regulators about components, risk weightings and other factors.

    The regulations define the relevant capital levels for the five categories.
In general terms, the capital definitions are as follows:

InterWest Bancorp is subject to risk-based capital guidelines issued by the
Federal Reserve Board (FRB), which establish a risk-adjusted ratio relating
capital to different categories of assets. InterWest Bancorp's Tier I capital
consists of shareholders' equity less certain intangibles, and excludes the
equity impact of adjusting securities available for sale to estimated fair
value. Total capital is Tier I capital and the allowance for losses on loans.
The FRB's risk-based capital rules have been supplemented by a leverage capital
ratio, defined as Tier I capital to adjusted quarterly average total assets. As
of September 30, 1999 and 1998, under the FRB's capital guidelines, InterWest
Bancorp's levels of consolidated regulatory capital exceeded the FRB's minimum
requirements.

    The capital amounts and ratios for InterWest Bancorp, InterWest Bank and
Pacific Northwest Bank as of September 30, 1999 and 1998 are presented in the

As of September 30, 1999, all subsidiary banks were in compliance with the
well-capitalized capital requirements. Management believes that under the
current regulations the subsidiary banks will continue to meet well-capitalized
capital requirements in the foreseeable future. However, events beyond the
control of the subsidiary banks, such as a downturn in the economy in areas
where the subsidiary banks have most of their loans, could adversely affect
future earnings and, consequently, the ability of the subsidiary banks to meet
future well-capitalized capital requirements.

    Currently, InterWest Bancorp pays quarterly dividends, which it intends
to continue to do. The funding source for dividends paid to shareholders is
dividends received from the subsidiary banks. The payment of dividends to
InterWest Bancorp from the subsidiary banks will be based on earnings and
financial condition and is subject to ongoing review by regulators and
various statutory limitations. Generally, InterWest is precluded from paying
dividends on its common stock if capital would be reduced to below regulatory
capital requirements at either the holding company or subsidiary bank level.
As of September 30, 1999, $49.3 million of retained earnings were available
for dividend distribution based on the capital levels and restrictions of
InterWest Bancorp and banking subsidiaries.

    As discussed in Note 24, InterWest Bancorp has issued capital securities
subsequent to September 30, 1999 that will qualify as Tier I capital.

NOTE 19
DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

    The estimated fair value amounts have been determined by InterWest using
available market information and appropriate valuation methodologies.
However, considerable judgment is necessary to interpret market data in the
development of the estimates of fair value. Accordingly, the estimates
presented herein are not necessarily indicative of the amounts InterWest
could realize in a current market exchange. The use of different market
assumptions and/or estimation methodologies may have a material impact on the
estimated fair value amounts. The following methods and assumptions were used
to estimate the fair value of each class of InterWest's financial instruments
as of September 30, 1999 and 1998:

CASH AND CASH EQUIVALENTS The carrying value is a reasonable estimate of the
fair value.

SECURITIES AVAILABLE FOR SALE, SECURITIES HELD TO MATURITY AND LOANS HELD FOR
SALE The estimated fair value of securities available for sale, securities
held to maturity and loans held for sale are based on quoted market rates and
dealer quotes.

LOANS RECEIVABLE The estimated fair value of loans receivable is based on
discounted cash flows, using estimated interest rates currently offered for
loans of similar characteristics.

    No adjustment was made to the estimated interest rates for changes in
credit of performing loans for which there are no known credit concerns.
Management believes that the risk factor embedded in the estimated interest
rates, along with the allowance for losses on loans applicable to the loan
portfolio, results in a fair valuation of such loans.

FHLB STOCK FHLB stock does not have a market and the estimated fair value is
unknown. As such, the carrying value is a reasonable estimate of the fair
value.

DEPOSITS The estimated fair value of deposits with no stated maturity, such
as checking accounts, money market and savings accounts, is equal to the
amount payable on demand as of September 30, 1999 and September 30, 1998,
respectively. The estimated fair value of certificates of deposit is based on
the discounted value of contractual cash flows. The discount rate is
estimated using the current rate for certificates of deposit with similar
characteristics.

FHLB ADVANCES, SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE AND OTHER
BORROWINGS The fair value of FHLB advances, securities sold under agreements
to repurchase and other borrowings are estimated based on the present values
using a discount rate equal to the rate currently offered on similar
borrowings with similar maturities.

OTHER The carrying value of other financial instruments has been determined
to be a reasonable estimate of their fair value.

NOTE 20
CONTINGENCIES

At periodic intervals, the FDIC, the Washington Department of Financial
Institutions, Division of Banks, the Office of the Comptroller of Currency,
the FRB and other regulatory agencies (collectively the regulators), examine
InterWest Bancorp and its banking subsidiaries as part of the regulatory
oversight of the banking industry. Based on their examinations, the
regulators may direct InterWest Bancorp or a subsidiary bank to adjust
financial statements in accordance with their findings. A future examination
by the regulators could include a review of certain transactions or other
amounts reported in InterWest's 1999 consolidated financial statements. The
regulators have not proposed significant adjustments to InterWest's
consolidated financial statements in prior years and management is not aware
of any basis for any such adjustments for 1999. In view of the uncertain
regulatory environment in which InterWest operates, the extent, if any, to
which a forthcoming examination may ultimately result in regulatory
adjustments to the 1999 consolidated financial statements cannot presently be
determined.

    In the normal course of business, InterWest has various legal claims and
other contingent matters outstanding. Management believes that any ultimate
liability arising from these actions will not have a material adverse impact
on InterWest's financial condition or results of operations.

    The subsidiary banks are required to maintain balances with the Federal
Reserve Bank based on a percentage of deposit liabilities. The average
required reserve as of September 30, 1999 and 1998, was $9,911,000 and
$10,597,000, respectively.

    During the year ended September 30, 1998, InterWest sold $26,709,000 of
single-family residential mortgage loans with recourse. As of September 30,
1999, $17,414,000 of these loans were outstanding.

BUSINESS SEGMENT INFORMATION

Currently, InterWest is managed at the subsidiary bank level, not by line of
business. As of September 30, 1999, the subsidiary banks of InterWest Bancorp
were InterWest Bank, Pacific Northwest Bank and Kittitas Valley Bank, N.A. Each
of these subsidiary banks has a board of directors and an executive management
team that is responsible for the operation and performance of the respective
subsidiary bank. InterWest currently has two reportable segments: InterWest Bank
and Commercial Banks.

    InterWest Bank is a state-chartered savings bank that was organized in 1956
as Island Savings and Loan Association in Oak Harbor, Washington, and
subsequently changed names to InterWest Bank. On July 18, 1995, InterWest Bank
completed a reorganization, in which InterWest Bank became a wholly owned
subsidiary of InterWest Bancorp. InterWest Bank is a community-oriented bank
which provides a wide range of financial services for individual and business
customers. InterWest Bank is currently in the process of transforming from a
traditional thrift to a full-service financial institution with commercial
banking in its portfolio of products. InterWest Bank conducts its business
through 40 full-service offices located in the western and north-central parts
of the state of Washington.

    The segment of Commercial Banks is defined as the collective operations of
the banking subsidiaries acquired by InterWest Bancorp during fiscal year 1998:
Pacific Northwest Bank, First National Bank of Port Orchard, Pioneer National
Bank and Kittitas Valley Bank, N.A. First National Bank of Port Orchard, which
was acquired by InterWest Bancorp on January 15, 1998, was merged into Pacific
Northwest Bank on October 15, 1998. Pioneer National Bank, which was acquired by
InterWest Bancorp on June 16, 1998, was merged into Pacific Northwest Bank on
January 22, 1999.

    Pacific Northwest Bank is a state-chartered commercial bank that was

engages in commercial banking activities, serving small to medium-sized
businesses as well as individuals. Pacific Northwest Bank conducts its business

SUBSEQUENT EVENTS

On November 15, 1999, $40,000,000 of 9.875 percent Capital Securities were
issued by InterWest Capital Trust I (the Trust). The Trust is a business
trust organized in November 1999, and 100 percent of the common equity of the
Trust is owned by InterWest Bancorp.
    The proceeds of the offering were invested by the Trust in junior
subordinated debentures of InterWest Bancorp. The debentures held by the
Trust are the sole assets of the Trust. Distributions on the capital
securities issued by the Trust are payable semiannually at 9.875 percent per
annum which is equal to the interest rate being earned by the Trust on the
debentures held by the Trust. The capital securities are subject to mandatory
redemption, in whole or in part, upon repayment of the debentures. The
debentures will not mature earlier than November 15, 2009, and not later than
November 15, 2029. InterWest Bancorp has entered into agreements which, taken
collectively, fully and unconditionally guarantee the capital securities
subject to the terms of each of the guarantees.
    InterWest Bancorp intends to use the net proceeds for general corporate
purposes. The capital securities will be included with borrowings as a
separate line item in the consolidated statements of financial condition and
InterWest will record distributions payable on the capital securities as
interest expense in the consolidated statements of income. The capital
securities will qualify as Tier 1 capital under the capital guidelines of the
Federal Reserve Board.
    On November 16, 1999, the Board of Directors of InterWest Bancorp
authorized the purchase of an additional 5 percent of InterWest Bancorp's
outstanding shares of common stock in the open market over a twelve-month
period.
