WESTBANK CORPORATION AND SUBSIDIARIES (UNAUDITED)
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
QUARTER AND NINE MONTHS ENDED SEPTEMBER 30, 2002 AND SEPTEMBER 30, 2001



NOTE A - GENERAL INFORMATION

Westbank Corporation (hereinafter sometimes referred to as "the Corporation") is
a registered Bank Holding Company organized to facilitate the expansion and
diversification of the business of Westbank (hereinafter sometimes referred to
as "the Bank") into additional financial services related to banking.
Substantially all operating income and net income of the Corporation are
presently accounted for by the Bank.

NOTE B - CURRENT OPERATING ENVIRONMENT

Westbank operates seventeen banking offices throughout western Massachusetts and
northeastern Connecticut, and also operates a Trust Department providing
services normally associated with holding property in a fiduciary or agency
capacity. A full range of retail banking services is furnished to individuals,
businesses and non-profit organizations. The primary source of revenue for
Westbank is derived from providing loans to customers who are predominantly
located in the Bank's service areas.

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
imposes significant regulatory restrictions and requirements on banking
institutions insured by the FDIC and their holding companies. FDICIA established
capital categories into which financial institutions are placed based on capital
level. Each capital category establishes different degrees of regulatory
restrictions that can apply to a financial institution. As of September 30,
2002, Westbank's capital was at a level that placed the Bank in the "well
capitalized" category as defined by FDICIA.

FDICIA imposes a variety of other restrictions and requirements on insured
banks. These include significant regulatory reporting requirements such as
insuring that a system of risk-based deposit insurance premiums and civil money
penalties for inaccurate deposit assessment reports exists. In addition, FDICIA
imposes a system of regulatory standards for bank and bank holding company
operations, detailed truth in savings disclosure requirements, and restrictions
on activities authorized by state law but not authorized for national banks.

extend credit. As of September 30, 2002, standby letters of credit amounted to
$152,000, loan commitments were $45,971,000 and unused balances available on
home equity lines of credit were $19,148,000.

Trust Assets - Property with a book value of $152,983,000 at September 30, 2002
held for customers in a fiduciary or agency capacity is not included in the
accompanying balance sheet since such items are not assets of the Bank.

The Massachusetts Department of Revenue ("DOR") has sent notices of intent to
assess taxes to several banks in the Commonwealth of Massachusetts. The notices
relate to DOR's intent to disallow the dividend-received deduction between a
bank and its subsidiary operating as a real estate investment trust ("REIT").

While the Corporation's subsidiary Westbank ("the Bank") has not received a
notice from the DOR, the Bank does operate a REIT similar to banks receiving
notices of assessment from the DOR.

Westbank believes that its tax treatment of the dividend-received deduction for
its REIT subsidiary is valid under Massachusetts law. Accordingly, the Bank
intends to continue its current accounting practice of calculating its tax
provision under the assumption that the dividend-received deduction is valid.

In the event that the dividend-received deduction from its REIT subsidiary is
disallowed, the Corporation would be required to record additional taxes of
approximately $641,000 for the years 2000, 2001 and 2002, exclusive of any
interest charge.

NOTE E - STOCKHOLDERS' EQUITY

The FDIC imposes leverage capital ratio requirements for state non-member banks
of 4%. In addition, the FDIC has established risk-based capital requirements for
insured institutions for Tier 1 risk-based capital of 4.00% and total risk-based
capital of 8.0%.

The capital ratios of the Bank were as follows:

    Total Risk-Based Capital                     12.16%              12.71%
</TABLE>

As of September 30, 2002, the Bank met the criteria for a well-capitalized
financial institution.

Capital guidelines issued by the Federal Reserve Board require the Corporation
to maintain certain capital ratios. Regulatory risk-based capital requirements
take into account the different risk categories of banking organizations by
assigning risk weights to assets and the credit equivalent amounts of
off-balance-sheet exposures. In addition, capital is divided into two (2) tiers.
For the Corporation, Tier 1 includes the common stockholders' equity and a
portion of the mandatory redeemable preferred stock; total risk-based, or
supplementary, capital includes not only the equity but also a portion of the
allowance for loan losses and a portion of the mandatory redeemable preferred
stock.

The Corporation's "Tier 1" leverage and risk-based capital ratios are as
follows:

NOTE F - RECENT ACCOUNTING PRONOUNCEMENTS

In April 2002, the Financial Accounting Standards Board("FASB") issued SFAS No.
145, "Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB
Statement No. 13, and Technical Corrections" ("SFAS No. 145"). The adoption of
SFAS No. 145 is not expected to have a material effect on the Corporation's
consolidated financial statements.

In April 2002, the Financial Accounting Standards Board ("FASB") issued SFAS No.
146, "Accounting for Costs Associated with Exit or Disposal Activities" ("SFAS
No. 146"). The adoption of SFAS No. 146 is not expected to have a material
effect on the Corporation's consolidated financial statements.

Effective January 1, 2002, the Corporation adopted Statement of Financial
Accounting Standards No. 141, "Business Combinations" ("SFAS No. 141") and SFAS
No. 142, "Goodwill and Other Intangible Assets" (SFAS No. 142"). Initially, the
adoption of SFAS No. 141 and SFAS No. 142 did not have an effect on the
Corporation's consolidated financial statements. In October 2002, the FASB
issued SFAS No. 147, "Acquisition of Certain Financial Institutions" ("SFAS No.
147"). SFAS No. 147 removes acquisitions of financial institutions from the
scope of SFAS No. 72, "Accounting for Certain Acquisitions of Banking or Thrift
Institutions" and FASB Interpretation No. 9, "Applying APB Opinions No. 16 and
17 When a Savings and Loan Association or Similar Association is Acquired in a
Business Combination Accounted for by the Purchase Method" and requires that
those transactions be accounted for in accordance with SFAS No. 141, "Business
Combinations", and SFAS No. 142, "Goodwill and Other Intangible Assets." In
addition, SFAS No. 147 amends SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets", to include in its scope long-term customer
relationship intangible assets of financial institutions. SFAS No. 147 is
effective for periods beginning after October 1, 2002, with early

adoption permitted. The Corporation elected to adopt SFAS No. 147 early, as of
September 30, 2002. Upon adoption of SFAS No. 147, the Corporation reclassified
its unidentifiable intangible asset to goodwill and ceased amortization,
retroactive to January 1, 2002. In accordance with SFAS No. 147, the
Corporation's statement of income for the nine-month period ended September 30,
2002 has been restated to remove the amortization expense of $342,000 ($205,000
net of taxes) that was recorded during the first two quarters of 2002. The
effect on earnings per share and diluted earnings per share is $0.05 and $0.04
for the nine months ended September 30, 2002. Additionally, the Corporation was
required to perform a transitional impairment test in accordance with the
provisions of SFAS No. 142. As a result of this testing, no impairment charges
were recorded. See Note G.

NOTE G - GOODWILL

Effective January 1, 2002, the Corporation adopted SFAS No. 142 and, effective
September 30, 2002, the Corporation adopted SFAS No. 147. In accordance with
these statements, the Corporation has ceased amortization of goodwill and has
performed a transitional goodwill impairment test. As a result of the
transitional impairment test, management has determined that no impairment
existed as of January 1, 2002, the date of adoption of SFAS No. 142.

The following table shows net income and earnings per share for the three and
nine months ended September 30, 2002 and 2001, as if the Corporation had been
accounting for goodwill under SFAS No. 142 and SFAS No. 147 for all periods
presented.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
NINE MONTHS ENDED SEPTEMBER 30, 2002 AND 2001


Information Concerning Forward-Looking Statements

The following forward-looking statements are made in accordance with the Private
Securities Litigation Reform Act of 1995.

The Corporation has made, and may make in the future, forward-looking statements
concerning future performance, including, but not limited to, future earnings
and events or conditions that may affect such future performance. These
forward-looking statements are based upon management's expectations and belief
concerning possible future developments and the potential effect of such future
developments on the Corporation. There is no assurance that such future
developments will be in accordance with management's expectations and belief or
that the effect of any future developments on the Corporation will be those
anticipated by management.

All assumptions that form the basis of any forward-looking statements regarding
future performance, as well as events or conditions that may affect such future
performance, are based on factors that are beyond the Corporation's ability to
control or predict with precision, including future market conditions and the
behavior of other market participants. Among the factors that could cause actual
results to differ materially from such forward-looking statements are the
following:

1.  The status of the economy in general, as well as in the Corporation's
    primary market areas of western Massachusetts and northeastern Connecticut;

2.  The real estate market in western Massachusetts and northeastern
    Connecticut;

3.  Competition in the Corporation's primary market area from other banks,
    especially in light of continued consolidation in the New England banking
    industry;

4.  Any changes in federal and state bank regulatory requirements;

5.  Changes in interest rates;

6.  The cost and other effects of unanticipated legal and administrative cases
    and proceedings, settlements and investigations;

7.  Unanticipated changes in laws and regulations, including federal and state
    banking laws and regulations, to which the Corporation and its subsidiaries
    are subject;

8.  Changes in accounting policies and practices, as may be adopted by the
    Financial Accounting Standards Board or any regulatory agency having
    authority over the Corporation and/or its subsidiaries; and

9.  Other risks and factors as discussed herein.

While the Corporation periodically reassesses material trends and uncertainties
affecting the Corporation's performance in connection with its preparation of
management's discussion and analysis of results of operations and financial
condition contained in its quarterly and annual reports, the Corporation does
not intend to review or revise any particular forward-looking statement.



Critical Accounting Policies

Management believes that Westbank's "Critical Accounting Policies" relate to
accounting for Securities and Loans, including revenue recognition.



                                       11
<PAGE>
Securities

Securities that management has the positive intent and ability to hold until
maturity are stated at cost, adjusted for amortization of premiums and accretion
of discounts. Those securities that have been identified as assets for which
there is not a positive intent to hold to maturity, including all marketable
equity securities, are classified as available for sale with unrealized gains
(losses), net of income taxes, reported as a separate component of stockholders'
equity. The Corporation determines if securities will be classified as
held-to-maturity or available-for-sale at the time of purchase. In addition, any
mortgage-backed securities created out of the Corporation's own inventory of
residential real estate loans are also considered available for sale. Gains and
losses on sales of available-for-sale securities are recognized in non-interest
income at the time of sale on a specific identification basis. Securities that
have experienced an other-than-temporary decline in value are written down to
estimated fair value, establishing a new cost basis with the amount of the
write-down expensed as a realized loss. The Corporation does not engage in
trading activities.

Loans

Loans have been reduced by deferred loan fees and the allowance for loan losses.

Interest income on loans is recorded on an accrual basis. Loan origination fees,
net of certain direct loan origination costs, are deferred and recognized as
income over the life of the related loan as an adjustment to the loan's yield.
Non-accrual loans are loans on which the accrual of interest ceases when the
collection of principal or interest payments is determined to be doubtful by
management. It is the general policy of the Corporation to discontinue the
accrual of interest when principal or interest payments are delinquent ninety
(90) days, unless the loan principal and interest are determined by management
to be fully collectible. Any unpaid amounts previously accrued on these loans
are reversed from income. Interest received on a loan in non-accrual status is
applied to reduce principal or, if management determines that the principal is
collectible, applied to interest on a cash basis. A loan is returned to accrual
status after the borrower has brought the loan current and has demonstrated
compliance with the loan terms for a sufficient period, and management's doubts
concerning collectibility have been removed.

The Corporation measures impairment of loans in accordance with SFAS No. 114,
"Accounting for Impairment of a Loan", as Amended by SFAS No. 118, "Accounting
by Creditors for Impairment of a Loan - Income Recognition and Disclosures"
(collectively, SFAS No. 114). A loan is recognized as impaired when it is
probable that either principal or interest are not collectible in accordance
with the terms of the loan agreement. Measurement of impairment for commercial
loans is generally based on the present value of expected future cash flows
discounted at the loan's effective interest rate. Commercial real estate loans
are generally measured based on the fair value of the underlying collateral. If
the estimated fair value of the impaired loan is less than the related recorded
amount, a specific valuation allowance is established or a write-down is charged
against the allowance for loan losses. Smaller balance homogenous loans,
including residential real estate and consumer loans, are excluded from the
provisions of SFAS No. 114. Generally, income is recorded only on a cash basis
for impaired loans.

The adequacy of the allowance for loan losses is evaluated quarterly by
management. Factors considered in evaluating the adequacy of the allowance
include the size and concentration of the portfolio, previous loss experience,
current economic conditions and their effect on borrowers, the financial
condition of individual borrowers and the related performance of individual
loans in relation to contract terms. The provision for loan losses charged to
operating expense is based upon management's judgment of the amount necessary to
maintain the allowance at a level adequate to absorb losses. Loan losses are
charged against the allowance for loan losses when management believes the
collectibility of the principal is unlikely.

Mortgage loans originated and intended for sale in the secondary market are
carried at the lower of cost or fair value in the aggregate. Net unrealized
losses are recognized through a valuation allowance charged to income.



                                       12

Changes in Financial Condition

Total consolidated assets amounted to $698,425,000 on September 30, 2002,
compared to $628,922,000 on December 31, 2001. As of September 30, 2002 and
December 31, 2001, earning assets amounted to, respectively, $653,078,000 or 94%
of total assets and $586,995,000 or 93% of total assets. Earning assets
increased during the first nine months of 2002 as a result of an increase in
loans and federal funds sold. Deposits and borrowings with the Federal Home Loan
Bank funded the growth in assets.

Changes in Results of Operations

For the quarter ended September 30, 2002, net income totaled $1,334,000,
compared to $940,000 for the quarter ended September 30, 2001. For the nine
months ended September 30, 2002, net income was $4,692,000, compared to
$2,978,000 for the same period during 2001.

Non-interest income increased by $57,000 during the third quarter of 2002
compared to the third quarter of 2001. During the third quarter of 2002, the
Corporation recognized a gain on the sale of securities available for sale of
$59,000 and a gain on the sale of mortgages totaling $45,000, while other
non-interest income totaled $862,000. Included in other non-interest income are
$225,000 in life insurance proceeds and $151,000 in write-downs of the Bank's
mortgage servicing assets. Non-interest expense totaled $3,956,000 for the
quarter ended September 30, 2002, a decrease of $473,000 versus the quarter
ended September 30, 2001, which included $270,000 of expenses related to the
merger of the Corporation's banking subsidiaries and $171,000 of goodwill
amortization.

An overall decrease in both interest income and interest expense reflects the
decrease in interest rates on earning assets and the decrease in rates on
interest-bearing liabilities, coupled with an increase in volume of earning
assets and interest-bearing liabilities for the quarter ended September 30,
2002. Further analysis is provided in sections on "Net Interest Income",
"Interest Rate Spread and Net Yield on Earning Assets", and "Changes in Net
Interest Income."

Allowance for Loan Losses and Non-Performing Assets

The Corporation's provision for loan losses in the current quarter was $400,000,
compared to $279,000 for the same period in 2001. Loans written off against the
allowance for loan losses after recoveries amounted to $151,000 for the quarter
ended September 30, 2002.

After giving effect to the actions described above, the allowance for loan
losses at September 30, 2002 totaled $4,932,000 or 1.05% of total loans, as
compared to $4,179,000 or 0.94% at December 31, 2001.

Non-performing and past due loans at September 30, 2002 aggregated $3,271,000 or
0.69% of total loans, compared to $1,830,000 or 0.41% at December 31, 2001. The
percentage of non-performing and past due loans compared to total assets on
those same dates, respectively, amounted to 0.47% and 0.32%. The increase in
non-performing loans in the current quarter is primarily the result of one
classified commercial mortgage loan being moved to non-performing status.

Other real estate owned decreased by $204,000 compared to 2001; as of September
30, 2002, the Corporation had no other real estate owned. The percentage of
other real estate owned to total assets as of September 30, 2002 and December
31, 2001 amounted to 0% and 0.01%, respectively.

Management has made every effort to recognize all circumstances known at this
time that could affect the collectibility of loans and has reflected these in
the provision for loan losses, the write-down of other real estate owned and
impaired loans to fair value and other loans (watch list) monitored by
management, the charge-off of loans and the balance in the allowance for loan
losses. Management believes that the provision for the quarter and the balance
in the allowance for loan losses, are adequate, based on results provided by the
loan grading system and circumstances known at this time.


                                       13

NET INTEREST INCOME

The Corporation's earning assets include a diverse portfolio of earning
instruments, ranging from the Corporation's core business of loan extensions to
interest-bearing securities issued by federal, state and municipal authorities.
These earning assets are financed through a combination of interest-bearing and
interest-free sources.

Net interest income, the most significant component of earnings, is the amount
by which the interest generated by assets exceeds the interest expense on
liabilities. For analytical purposes, the interest earned on tax exempt assets
is adjusted to a "tax equivalent" basis to recognize the income tax savings,
which facilitates comparison between taxable and tax exempt assets.

The Corporation analyzes its performance by utilizing the concepts of interest
rate spread and net yield on earning assets. The interest rate spread represents
the difference between the yield on earning assets and interest paid on
interest-bearing liabilities. The net yield on earning assets is the difference
between the rate of interest on earning assets and the effective rate paid on
all funds - interest-bearing liabilities as well as interest-free sources
(primarily demand deposits and shareholders' equity).

LIQUIDITY

The Corporation's liquidity represents the ability to meet loan commitments,
deposit withdrawals and any other cash needs as they arise. Funds to meet
liquidity are available by converting liquid assets or by generating new
deposits or through other funding sources. Factors affecting a bank's liquidity
needs include changes in interest rates, demand for loan products and general
economic conditions. The Corporation has alternative sources of liquidity,
including federal funds lines of credit, lines of credit available through the
Federal Home Loan Bank of Boston and repurchase agreements. Management believes
that the Corporation's level of liquidity is adequate to meet current and future
funding needs.

</TABLE>

The approach the Corporation uses in determining the adequacy of the allowance
for loan losses is an exposure method based on the Corporation's loan loss
history. Quarterly, based on an internal review of the loan portfolio, the
Corporation identifies required reserve allocations targeted to recognized
problem loans that, in the opinion of management, have potential loss exposure
or questions relative to the depth of the collateral on these same loans. In
addition, the Corporation allocates a general reserve against the remainder of
the loan portfolio, based on the overall mix of the loan portfolio and the loss
history of each loan category.
