            CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(1)  Basis of Presentation

     The financial condition and results of operations of MASSBANK Corp. (the
"Company") essentially reflect the operations of its subsidiary, MASSBANK (the
"Bank"). All significant intercompany balances and transactions have been
eliminated in consolidation.

     The accompanying financial statements have been prepared in accordance with
accounting principles generally accepted in the United States of America and in
the opinion of management, include all adjustments of a normal recurring nature
necessary for the fair presentation of the financial condition of the Company as
of June 30, 2002 and December 31, 2001, and its operating results for the six
months ended June 30, 2002 and 2001. The results of operations for any interim
period are not necessarily indicative of the results to be expected for the
entire year.

     Certain amounts in the prior years' consolidated financial statements were
reclassified to facilitate comparison with the current fiscal year. The
Company's reported per share amounts and weighted average common shares
outstanding for the current and prior year have been restated to reflect the
Company's three-for-two stock split of April 19, 2002.

     The information in this report should be read in conjunction with the
financial statements and related notes included in the Annual Report on Form
10-K for the year ended December 31, 2001.

directors. The plan allows the Company's directors to defer receipt of all or a

their termination as a director of the Company. The plan was later amended to
allow the directors' compensation to be invested in Company stock held in an

book value per share.

enterprise during a period from transactions and other events and circumstances

     The term "comprehensive income" describes the total of all components of
comprehensive income including net income.

Results of Operations for the three months ended June 30, 2002

GENERAL

     For the quarter ended June 30, 2002, MASSBANK Corp. reported net income of
$2,702,000, or $0.56 in diluted earnings per share compared to net income of
$2,688,000 or $0.56 in diluted earnings per share in the second quarter of 2001.
Basic earnings per share in the recent quarter were $0.57 per share, unchanged
from the same quarter last year. The current and prior year per share amounts
reflect the three-for-two split of the Company's common stock that occurred on
April 19, 2002.

     The Company's net income for the second quarter 2002 compared to the same
quarter of 2001 reflects an improvement of $390,000 in net interest income after
provision for loan losses. This increase, however, is partially offset by a
decrease in non-interest income of $316,000 due primarily to lower securities
gains in the recent quarter. Earnings results for the second quarter 2002 also
reflect a slight increase in the Company's effective income tax rate.

Net interest income

     Net interest income totaled $6,007,000 in the second quarter of 2002, an
increase of $378,000 from the same quarter a year ago. This is the third
consecutive quarter that the Company has increased its net interest income. The
increase was principally attributable to an improvement in the Company's net
interest margin combined with the positive effect of average earning asset
growth. The Company's net interest margin for the three months ended June 30,
2002 was 2.49%, an increase from 2.41% reported in the second quarter of 2001.
Average earning assets for the quarter ended June 30, 2002 increased $33.7
million to $969.7 million, from $936.0 million in the same quarter of 2001.

Interest and Dividend Income

     Interest and dividend income on a fully taxable equivalent basis for the
three months ended June 30, 2002, decreased $2,154,000 or 15.3% to $11,969,000
from $14,123,000 for the three months ended June 30, 2001. The decrease in
interest and dividend income resulted from a decrease in yield on the Company's
average earning assets, partially offset by the higher interest income resulting
from an increase of $33.7 million in average earning assets. As reflected in the
table on page 14 of this report, the yield on the Company's average earning
assets in the second quarter of 2002 was 4.94%, down from 6.04% in the same
quarter of 2001.

     The reduction in yield on the Company's average earning assets is primarily
attributable to lower market interest rates. During the period April 1, 2001 to
June 30, 2002, the Federal Reserve Bank cut the Federal Funds rate eight times,
reducing the rate from 5.00% to 1.75%. Due to the Company's large balance of
overnight Federal Funds, this Federal Funds rate reduction contributed
significantly to the decrease in the Company's interest and dividend income in
the second quarter 2002.

     Total interest expense for the three months ended June 30, 2002 decreased
$2,533,000, or 29.9% to $5,943,000 from $8,476,000 for the three months ended
June 30, 2001. The decrease in interest expense is due primarily to a reduction
in the Bank's average cost of funds, partially offset by an increase in interest
expense due to higher average deposits. A decrease in the Bank's deposit rates,
due to declining market interest rates in the last twelve months, has caused the
Bank's cost of funds to decrease 133 basis points, from 4.07% in the second
quarter of 2001 to 2.74% in the recent quarter. The Company's average deposits,
as shown in the table on page 15, increased $32.7 million to $868.6 million in
the second quarter of 2002, from $835.9 million in the second quarter of 2001.

Provision for Loan Losses

     The provision for loan losses represents a charge against current earnings
and an addition to the allowance for loan losses. There was no provision for
loan losses in the second quarter of 2002. This compares to a $12,000 provision
for loan losses in the second quarter of last year. In determining the amount to
provide for loan losses, the key factor is the adequacy of the allowance for
loan losses. Management uses a methodology to systematically measure the amount
of estimated loan loss exposure inherent in the portfolio for purposes of
establishing a sufficient allowance for loan losses. The methodology includes
three elements: an analysis of individual loans deemed to be impaired in
accordance with the terms of Statement of Financial Accounting Standard No. 114,
"Accounting by Creditors for Impairment of a Loan", general loss allocations for
various loan types based on loss experience factors and an unallocated allowance
which is maintained based on management's assessment of many factors including
the risk characteristics of the portfolio, concentrations of credit, current and
anticipated economic conditions that may effect the borrower's ability to pay,
and trends in loan delinquencies and charge-offs. Realized losses, net of
recoveries, are charged directly to the allowance. While management uses the
information available in establishing the allowance for loan losses, future
adjustments to the allowance may be necessary if economic conditions differ from
the assumptions used in making the evaluation. In addition, various regulatory
agencies, as an integral part of their examination process, periodically review
the Bank's allowance for loan losses. Such agencies may require the Bank to
recognize additions to the allowance based on judgments different from those of
management. At June 30, 2002, the allowance for loan losses was $2,642,000
representing 655.6% of nonaccrual loans. The Bank's nonaccrual loans totaled
$403,000 at June 30, 2002 down from $644,000 at December 31, 2001 and $472,000
at June 30, 2001. The Bank had net loan charge-offs of $1,000 in the recent
quarter compared to net loan charge-offs of $3,000 in the same quarter last
year. Management believes that the allowance for loan losses as of June 30, 2002
is adequate to cover the risks inherent in the loan portfolio under current
conditions.

                                       16



Non-Interest Income

     Non-interest income consists of deposit account service fees, net gains on
securities and other non-interest income.

     Non-interest income decreased $316,000 to $1,236,000 in the recent quarter,
from $1,552,000 in the comparable quarter of the prior year. This decrease is
due primarily to lower securities gains in the second quarter of 2002.

     Net gains on securities available for sale totaled $750,000 in the second
quarter of this year compared to $1,122,000 in the second quarter of last year.
Realized gains on the sale of equity securities and debt securities totaled
$684,000 and $106,000, respectively, for the three months ended June 30, 2002.
In addition, the Company in the recent quarter recorded a charge to earnings of
$40,000 due to an equity security in its investment securities portfolio having
suffered a loss in value which was considered by management to be other than
temporary. Due to the decline in equity market prices over the past six months
the Company expects that opportunities for securities gains from the equity
portfolio will be substantially reduced in future quarters. In addition, if
these market conditions persist or deteriorate further, the Company may incur
losses in its equity securities portfolio.

     Net gains on trading securities increased to $168,000 in the recent quarter
from $18,000 in the same quarter last year. During the second quarter 2002, the
Company recorded net trading securities gains on sales of U.S. Treasury
obligations and marketable equity securities of $13,000 and $8,000,
respectively. Net gains on trading securities in the recent quarter also include
mark-to-market gains on U.S. Treasury obligations of $147,000. Falling interest
rates and recent volatility in the bond markets has provided the Company with
trading gains that may not be available in future periods.

     The Bank's deposit account service fees and other non-interest income
totaled $141,000 and $177,000, respectively, in the second quarter of 2002
compared to $159,000 and $253,000, respectively, in the second quarter of 2001.
The decline in other non-interest income is due primarily to the assets in the
Company's deferred compensation plan having declined in market value in the
recent quarter versus having appreciated in value in the same quarter last year.
This decrease is offset by a corresponding decline in non-interest expense under
the salaries and employee benefits expense component.

Non-Interest Expense

     Non-interest expense for the second quarter 2002 remained essentially
unchanged from the same quarter last year. Total non-interest expense decreased
$4,000 to $2,987,000.

     Salaries and employee benefits, the largest component of non-interest
expense increased $105,000 or 6.2% to $1,800,000 in the recent quarter, from
$1,695,000 in the comparable quarter of 2001. This increase reflects higher
salaries due to merit increases, higher pension costs and an increase in costs
associated with various other employee benefits partially offset by a decrease
in deferred compensation expense referred to in the non-interest income section
above.

     Occupancy and equipment expenses declined $40,000 to $473,000 in the recent
quarter, from $513,000 in the same quarter last year. This decrease is due in
part to the construction of one new branch and the purchase of another branch,
replacing existing leases and reducing net occupancy expenses.

     Amortization of intangibles expense decreased $80,000 in the first quarter
2002, compared to the first quarter last year. This expense decreased for the
following reasons:

                                       17



     1.  The deposit acquisition premium that the Bank recorded in 1992 in
         connection with its acquisition of the deposits and certain assets of
         the former Central Savings Bank, Lowell was fully amortized in February
         2002.

     2.  On January 1, 2002 the Company adopted Statement of Financial
         Accounting Standard ("SFAS") No. 142, "Goodwill and Other Intangible
         Assets." SFAS 142 requires that upon adoption of the Statement, any
         goodwill recorded on a company's balance sheet would no longer be
         amortized, but be reviewed for impairment periodically or upon the
         occurrence of certain triggering events. At January 1, 2002 the Company
         had $1,090,000 of goodwill on its balance sheet that was previously
         being amortized at a rate of $25,000 per quarter.

     All other non-interest expenses combined, consisting of data processing,
professional services, advertising and marketing, deposit insurance and other
expenses, increased $11,000 to $714,000 for the three months ended June 30, 2002
from $703,000 for the three months ended June 30, 2001.

Income Tax Expense

    The Company, the Bank and its subsidiaries file a consolidated federal
income tax return. The Parent Company is subject to a State of Delaware
Franchise Tax and a State of Massachusetts Bank Excise Tax and the Bank's
subsidiaries are subject to a State of Massachusetts Corporate Excise Tax.

     The Company recorded income tax expense of $1,554,000 in the second quarter
of 2002, an increase of $64,000 when compared to the same quarter last year. The
increase in income tax expense is due primarily to an increase in income before
income taxes and an increase in effective income tax rate. The Company's income
before income taxes was $4,256,000 in the recent quarter compared to $4,178,000
for the same quarter a year ago. The effective income tax rate for the three
months ended June 30, 2002 and 2001 was 36.5% and 35.7%, respectively.

                                       18



Results of Operations for the six months ended June 30, 2002

General

     For the six months ended June 30, 2002, the Company reported net income of
$5,352,000 or $1.10 in diluted earnings per share ($1.13 in basic earnings per
share) compared to net income of $5,433,000 or $1.13 in diluted earnings per
share ($1.16 in basic earnings per share) for the six months ended June 30,
2001. The current and prior year per share amounts reflect the three-for-two
split of the Company's common stock that occurred on April 19, 2002.

     The Company's financial performance in the first six months of 2002
reflects an increase in net interest income after provision for loan losses of
$367,000. This increase, however, is offset by a decrease in non-interest income
of $231,000 due primarily to lower securities gains in the first half of 2002,
and an increase in non-interest expense of $164,000. Earnings results for the
six months ended June 30, 2002 also reflect a slight increase in the Company's
effective income tax rate.

Net Interest Income

     Net interest income totaled $11,953,000 for the six months ended June 30,
2002, compared to $11,610,000 for the same period in 2001. The $343,000 increase
is primarily attributable to an increase in average earning assets, partially
offset by a decrease in the Company's net interest margin.

     The Company's net interest margin for the first six months of 2002 was
2.49% compared to 2.50% for the same period last year. Average earning assets
for the six months ended June 30, 2002 increased $33.2 million to $964.0 million
from $930.8 million for the corresponding period in 2001.

     The Company's interest rate spread for the first half of 2002 increased to
2.18% from 2.02% for the first six months of last year. The yield on the
Company's average earning assets in the first half of 2002 decreased 125 basis
points to 4.99% from 6.24% in the corresponding period of 2001. The Company's
average cost of funds for the first half of 2002 decreased 141 basis points to
2.81% from 4.22% for the six months ended June 30, 2001.

                                       21



Provision for Loan Losses

     The provision for loan losses represents a charge against current earnings
and an addition to the allowance for loan losses. There was no provision for
loan losses in the first half of 2002. This compares to a $24,000 provision for
loan losses in the first half of last year. The Bank has made no provision for
loan losses in 2002 because it has had minimal net loan charge-offs in the
current and prior year. Net loan charge-offs for the six months ended June 30,
2002 and 2001 were $1,000 and $2,000, respectively. In addition, management
believes that the allowance for loan losses as of June 30, 2002 is adequate to
cover the risks inherent in the loan portfolio under current conditions.

Non-Interest Income

     Non-interest income consists of deposit account service fees, net gains on
securities and other non-interest income.

     Non-interest income decreased $231,000 to $2,492,000 for the first six
months of 2002 from $2,723,000 for the same period of the prior year. This
decrease is due primarily to lower securities gains in the first half of 2002.

     Net gains on securities available for sale totaled $1,749,000 in the first
half of 2002 compared to $1,901,000 in the first half of last year. Realized
gains on the sale of equity securities and debt securities totaled $1,680,000
and $109,000, respectively, for the six months ended June 30, 2002. In addition,
the Company in the first half of 2002 recorded a charge to earnings of $40,000
due to an equity security in its investment securities portfolio having suffered
a loss in value which was considered by management to be other than temporary.
Due to the decline in equity market prices over the past six months the Company
expects that opportunities for securities gains from the equity portfolio will
be substantially reduced in future quarters. In addition, if these market
conditions persist or deteriorate further, the Company may incur losses in its
equity securities portfolio.

     Net gains on trading securities increased to $102,000 for the first six
months of 2002 from $96,000 for the same period last year. During the first half
of 2002, the Company recorded net trading securities gains on sales of
marketable equity securities and U.S. Treasury obligations of $22,000 and
$15,000, respectively. Net gains on trading securities in the first half of 2002
also include mark-to-market gains on U.S. Treasury obligations of $65,000.
Falling interest rates and recent volatility in the bond markets has provided
the Company with trading gains that may not be available in future periods.
Trading gains in the bond portfolio are more likely during periods of falling
interest rates.

     The Bank's deposit account service fees and other non-interest income
totaled $287,000 and $354,000, respectively, for the first half of 2002 compared
to $320,000 and $406,000, respectively, for the first half of 2001. The decline
in other non-interest income is due primarily to the assets in the Company's
deferred compensation plan having declined in market value in the six month
period ended June 30, 2002 versus having appreciated in value in the same period
last year. This decrease is offset by a corresponding decline in non-interest
expense under the salaries and employee benefits expense component.

Non-Interest Expense

     Non-interest expense for the six months ended June 30, 2002 increased
$164,000 or 2.8% to $6,022,000 from $5,858,000 for the same period last year.
This increase is due primarily to increases in salaries and employee benefits
and professional services expenses.

                                       22



     Salaries and employee benefits, the largest component of non-interest
Expense increased $343,000 or $10.4% to $3,626,000 for the first half of 2002,
from $3,283,000 for the comparable period of 2001. This increase reflects higher
salaries due to merit increases, higher pension costs and an increase in costs
associated with various other employee benefits partially offset by a decrease
in deferred compensation expense referred to in the non-interest income section
above.

     Occupancy and equipment expenses declined $97,000 or 8.9% to $994,000 for
the first half of 2002, from $1,091,000 for the same period last year. This
decrease is due in part to the construction of one new branch and the purchase
of another branch, replacing existing leases and reducing net occupancy
expenses.

     Professional services expense increased $47,000 or 18.9% to $296,000 for
the first six months of 2002, from $249,000 for the same period last year. The
increase is due primarily to higher legal and audit fees.

     Amortization of intangibles expense decreased $133,000 for the first half
of 2002, compared to the same period last year. This expense decreased for the
following reasons:

     1.  The deposit acquisition premium that the Bank recorded in 1992 in
         connection with its acquisition of the deposits and certain assets of
         the former Central Savings Bank, Lowell was fully amortized in February
         2002.

     2.  On January 1, 2002 the Company adopted Statement of Financial
         Accounting Standard ("SFAS") No. 142, "Goodwill and Other Intangible
         Assets." SFAS 142 requires that upon adoption of the Statement, any
         Goodwill recorded on a company's balance sheet would no longer be
         amortized, but be reviewed for impairment periodically or upon the
         occurrence of certain triggering events. At January 1, 2002 the Company
         had $1,090,000 of goodwill on its balance sheet that was previously
         being amortized at a rate of $25,000 per quarter.

     All other non-interest expenses combined, consisting of data processing,
advertising and marketing, deposit insurance and other expenses, increased
$4,000 to $1,077,000 for the six months ended June 30, 2002 from $1,073,000 for
the six months ended June 30, 2001.

Income Tax Expense

     The provision for federal and state income taxes increased to $3,071,000
for the six months ended June 30, 2002 from $3,018,000 for the same period in
2001. This increase is due primarily to an increase in the Company's effective
income tax rate partially offset by lower income before income taxes in the
first half of 2002. The Company's combined effective income tax rate for the
first half of 2002 is 36.5% compared to 35.7% for the same period a year ago.
The Company's income before income taxes was $8,423,000 for the first half of
2002 compared to $8,451,000 for the first half of 2001.

                                       23



Financial Condition

     The Company's total assets amounted to $996.4 million as of June 30, 2002,
an increase of $25.2 million or 2.6% from $971.2 million at December 31, 2001.
This reflects an increase in total investments of $19.5 million or 3.2% and a
decrease in the Bank's loan portfolio of $2.1 million or less than 1%. Cash and
due from banks increased $1.5 million and all other assets increased $6.3
million.

                                   Investments

     At June 30, 2002, the Company's investment portfolio, consisting of
investment securities (including mortgage-backed securities), short-term
investments and interest-bearing bank deposits totaled $638.0 million
representing 64.0% of total assets, compared to $618.5 million or 63.7% of total
assets at December 31, 2001. The investment securities portfolio included U.S.
government and agency obligations, 15-year mortgage-backed securities,
collateralized mortgage obligations and equity securities. For further
information concerning the composition, maturity and market value of the Bank's
investment securities, see pages 26 through 28 of this Form 10-Q.

                                      Loans

     The loan portfolio decreased $2.1 million or less than 1% in the first six
months of 2002. At June 30, 2002, the loan portfolio, net of allowance for loan
losses, was $326.3 million representing 32.7% of total assets compared to $328.4
million representing 33.8% of total assets at December 31, 2001.

     The majority of loans in the portfolio are residential mortgages.
Residential mortgages amounted to $308.0 million at June 30, 2002, representing
93.6% of the total loan portfolio. See page 29 of this Form 10-Q for a table
setting forth the composition of the loan portfolio at June 30, 2002 and year-
end 2001.

     Lower interest rates in the beginning of the year 2002 resulted in
increased loan origination growth for the Bank. In the first six months of 2002,
the Bank originated loans of $54.3 million, an increase of $10.4 million or
23.7% from the $43.9 million in loans originated in the first six months of
2001.

                                  Asset Quality

     Asset quality remains strong. Non-accrual loans, generally those loans
which are 90 days or more delinquent, were $403 thousand and $644 thousand,
respectively, at June 30, 2002 and December 31, 2001. This represents 0.12% of
total loans at June 30, 2002.

     The Bank's allowance for loan losses at June 30, 2002 totaled $2.6 million,
representing 656% of non-accrual loans and 0.80% of total loans. The Bank
believes that its allowance for loan losses is adequate to cover the risks
inherent in the loan portfolio under current conditions. The Bank has no real
estate acquired through foreclosure at June 30, 2002.

                                    Deposits

     Deposits have historically been the Bank's primary source of funds for
lending and investment activities. Deposit flows vary significantly and are
influenced by prevailing interest rates, market conditions, economic conditions
and competition. The Bank's management attempts to manage its deposits through
selective pricing and marketing. Deposits increased $24.2 million or 2.8% to
$873.9 million at June 30, 2002 from $849.7 million at December 31, 2001. This
increase was primarily the result of an increase in savings and money market
account deposits of $87.1 million or 22.7%, partially offset by a decrease in
time certificates of deposit of $65.1 million or 17.0%. Other deposits grew by
$2.2 million during the first half of 2002. For information concerning the
composition of the Bank's deposits at June 30, 2002 and year-end 2001, see page
32 of this Form 10-Q.

                                       24



Financial Condition (continued)

                               Stockholders Equity

     Total stockholders' equity increased to $116.5 million at June 30, 2002,
representing a book value per share of $24.80, from $114.9 million representing
a book value per share of $24.34 at December 31, 2001. The Company's book value
per share as of year-end 2001 has been adjusted to reflect the three-for- two
split of the Company's common stock on April 19, 2002.

Investments

     As previously noted, total investments consisting of investment securities,
short-term investments and interest-bearing bank deposits equaled $638.0 million
at June 30, 2002, up $19.5 million from $618.5 million at year-end 2001. These
investments are principally in federal funds sold, U.S. Treasury and government
agency obligations, government agency fifteen year mortgage-backed securities,
collateral mortgage obligations and bank certificates of deposit. The Bank also
maintains an equity securities portfolio, valued at $11.8 million as of June 30,
2002, that has yielded substantial realized and unrealized gains in recent
years. While the Company's equity securities portfolio has produced increased
realized gains in recent years, management does not expect this trend to
continue. Due to the decline in equity market prices over the past six months
the Company expects that opportunities for securities gains from the equity
portfolio will be substantially reduced in future quarters. In addition, if
these market conditions persist or deteriorate further, the Company may incur
losses in its equity securities portfolio.

     Nearly all of the Bank's investment securities are classified as available
for sale or trading securities. Management evaluates its investment alternatives
in order to properly manage the mix of assets on its balance sheet. Investment
securities available for sale and trading securities provide liquidity,
facilitate interest rate sensitivity management and enhance the Bank's ability
to respond to customers' needs should loan demand increase and/or deposits
decline.

     The Bank continues to maintain a large proportion of its securities
portfolio in government agency mortgage-backed securities. These represent an
attractive investment with minimal credit risk, no servicing responsibilities,
and no delinquencies. The Bank's investment in mortgage-backed securities
totaled $238.0 million at June 30, 2002 versus $265.0 million at year-end 2001.

     The Bank also maintains a portfolio of trading securities which consisted
of the following as of the dates shown:

- ---------------------------------------------------------------------------------------


     The Bank's loan portfolio decreased $2.1 million in the first six months of
2002, from $331.0 million at December 31, 2001 to $328.9 million at June 30,
2002. Mortgage loans increased $14.0 million, however, this increase was offset
by a decrease in consumer loans of $1.1 million and a decrease of $15.0 in
commercial loans. The decrease in commercial loans is due to a loan with a
single borrower that was repaid in the recent quarter. The loan was refinanced
with another financial institution.

     Loan originations increased by $10.4 million to $54.3 million in the first
six months of 2002 compared to $43.9 million in the first six months of last
year.

- --------------------------------------------------------------------------------

     The Bank generally does not accrue interest on loans which are 90 days or
more past due. It is the Bank's policy to place such loans on non-accrual status
and to reverse from income all interest previously accrued but not collected and
to discontinue all amortization of deferred loan fees.

     Non-performing assets decreased from December 31, 2001 to June 30, 2002 as
noted in the table above. The principal balance of non-accrual loans was down to
$403,000, or approximately 0.12% of total loans at June 30, 2002.

     The Bank did not have any impaired loans as of June 30, 2002.

     An analysis of the activity in the allowance for loan losses is as follows:

- --------------------------------------------------------------------------

     The Company maintains an allowance for probable losses that are inherent in
the Company's loan portfolio. The allowance for loan losses is increased by
provisions charged to operations based on the estimated loan loss exposure
inherent in the portfolio. Management uses a methodology to systematically
measure the amount of estimated loan loss exposure inherent in the portfolio for
purposes of establishing a sufficient allowance for loan losses. The methodology
includes three elements: an analysis of individual loans deemed to be impaired
in accordance with the terms of Statement of Financial Accounting Standard No.
114, "Accounting by Creditors for Impairment of a Loan," general loss
allocations for various loan types based on loss experience factors and an
unallocated allowance which is maintained based on management's assessment of
many factors including the risk characteristics of the portfolio, concentrations
of credit, current and anticipated economic conditions that may effect the
borrower's ability to pay, and trends in loan delinquencies and charge-offs.
Realized losses, net of recoveries, are charged directly to the allowance. While
management uses the information available in establishing the allowance for loan
losses, future adjustments to the allowance may be necessary if economic
conditions differ from the assumptions used in making the evaluation. In
addition, various regulatory agencies, as an integral part of their examination
process, periodically review the Bank's allowance for loan losses. Such agencies
may require the Bank to recognize additions to the allowance based on judgments
different from those of management.

     At June 30, 2002 the balance of the allowance for loan losses was
$2,642,000 representing 655.6% of non-accrual loans. Management believes that
the allowance for loan losses is adequate to cover the risks inherent in the
portfolio under current conditions.

DEPOSITS

     Deposit accounts of all types have traditionally been the primary source of
funds for the Bank's lending and investment activities. The Bank's deposit flows
are influenced by prevailing interest rates, competition and other market
conditions. The Bank's management attempts to manage its deposits through
selective pricing and marketing.

     The Bank's total deposits increased by $24.2 million to $873.9 million at
June 30, 2002 from $849.7 million at December 31, 2001.

     The composition of the Bank's total deposits as of the dates shown are
summarized as follows:

Recent Accounting Developments

     "Goodwill and Other Intangible Assets"
     In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standard ("SFAS") No. 142, "Goodwill and Other
Intangible Assets." SFAS 142 requires that upon adoption of the Statement, any
goodwill recorded on an entity's balance sheet would no longer be amortized.
This would include existing goodwill (i.e., recorded goodwill at the date the
financial statement is issued), as well as goodwill arising subsequent to the
effective date of the Statement. Goodwill will not be amortized but will be
reviewed for impairment periodically or upon the occurrence of certain
triggering events. This Statement is effective for fiscal years beginning after
December 15, 2001. The Company adopted the new standard on January 1, 2002. At
June 30, 2002, the Company had $1,090,000 of goodwill on its balance sheet.

Liquidity and Capital Resources

     The Bank must maintain a sufficient amount of cash and assets which can
readily be converted into cash in order to meet cash outflows from normal
depositor requirements and loan demands. The Bank's primary sources of funds are
deposits, loan and mortgage-backed securities amortization and prepayments,
sales or maturities of investment securities, investment securities called
before maturity and income on earning assets. In addition to loan payments and
maturing investment securities, which are relatively predictable sources of
funds, the Bank maintains a high percentage of its assets invested in overnight
federal funds sold, which can be immediately converted into cash and United
States Treasury and Government agency securities, which can be sold or pledged
to raise funds. At June 30, 2002 the Bank had $182.9 million or 18.4% of total
assets and $176.1 million or 17.7% of total assets invested, respectively, in
overnight federal funds sold and United States obligations.

     The Bank is a Federal Deposit Insurance Corporation ("FDIC") insured
institution subject to the FDIC regulatory capital requirements. The FDIC
regulations require all FDIC insured institutions to maintain minimum levels of
Tier 1 capital. Highly rated banks (i.e., those with a composite rating of 1
under the CAMELS rating system) are required to maintain a minimum leverage
ratio of Tier 1 capital to total assets of at least 3.00%. An additional 100 to
200 basis points are required for all but these most highly rated institutions.
The Bank is also required to maintain a minimum level of risk-based capital.
Under the risk-based capital standards, FDIC insured institutions must maintain
a Tier 1 capital to risk-weighted assets ratio of 4.00% and are generally
expected to meet a minimum total qualifying capital to risk-weighted assets
ratio of 8.00%. The risk-based capital guidelines take into consideration risk
factors, as defined by the regulators, associated with various categories of
assets, both on and off the balance sheet. Under the guidelines, capital
strength is measured in two tiers which are used in conjunction with risk
adjusted assets to determine the risk-based capital ratios. Tier II components
include supplemental capital components such as qualifying allowance for loan
losses and qualifying subordinated debt and up to 45 percent of the pre-tax net
unrealized holding gains on certain available for sale equity securities. Tier I
capital plus the Tier II capital components are referred to as total qualifying
capital.

     The capital ratios of the Bank and the Company currently exceed the minimum
regulatory requirements. At June 30, 2002, the Bank had a leverage Tier I
capital to total assets ratio of 10.32%, a Tier I capital to risk- weighted
assets ratio of 30.70% and a total capital to risk-weighted assets ratio of
31.50%. The Company, on a consolidated basis, had ratios of leverage Tier I
capital to total assets of 10.98%, Tier I capital to risk-weighted assets of
32.66% and total capital to risk-weighted assets of 33.45% at June 30, 2002.

Impact Of Inflation And Changing Prices

     MASSBANK Corp.'s financial statements presented herein have been prepared
in accordance with generally accepted accounting principles which require the
measurement of financial position and operating results in terms of historical
dollars, without considering changes in the relative purchasing power of money
over time, due to the fact that substantially all of the assets and liabilities
of a financial institution are monetary in nature. As a result, interest rates
have a more significant impact on a financial institution's performance than the
effects of general levels of inflation. Interest rates do not necessarily move
in the same direction or in the same magnitude as the prices of goods and
services.
