MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL

The following discussion should be read in conjunction with the consolidated
financial statements and related notes included in this report. Certain amounts
reported for prior years have been reclassified to conform to the 2000
presentation. The discussion contains certain forward-looking statements
regarding the future performance of the Company. All forward-looking information
is inherently uncertain and actual results may differ substantially from the
assumptions, estimates, or expectations reflected or contained in the
forward-looking information.

         The financial condition and results of operations of Massbank Corp.
(the "Company") essentially reflect the operations of its subsidiary, Massbank
(the "Bank").

         The Company's consolidated net income depends largely upon net interest
income, which is the difference between interest income from loans and
investments ("interest-earning assets") and interest expense on deposits and
borrowed funds ("interest-bearing liabilities"). Net interest income is
significantly affected by general economic conditions, policies established by
regulatory authorities and competition.

         The Company's earnings results are also affected by the provision for
loan losses; non-interest income, such as fee-based revenues and net securities
gains or losses; non-interest expense; and income taxes.

FINANCIAL CONDITION

The Company's total assets increased $14.0 million to $938.7 million as of
December 31, 2000, as a result of an increase in total investments of $28.6
million partially offset by a decrease in the bank's loan portfolio, net of
allowance for loan losses, of $15.3 million. Other assets reflect an increase of
$0.7million as of December 31, 2000 from year-end 1999.

         The Company's total investments consisting of investment securities and
other short-term investments, including term federal funds sold and
interest-bearing bank deposits increased $28.6 million from $578.5 million at
December 31, 1999 to $607.1 million at year-end 2000. The increase is
attributable to an increase in term federal funds sold, trading securities and
short-term investments of $30.0 million, $13.8 million and $1.9 million,
respectively. These were partially offset by a decrease in longer-term
investments. One of the primary components of the Bank's investment securities
portfolio, U.S. Treasury and Government agency securities decreased by $18.0
million in 2000. This decrease was partially offset by an increase of $4.9
million in mortgage-backed securities. Other investments decreased by $4.0
million in 2000.

         During the second half of 2000 the interest rate curve was either flat
or inverted. As a result of long-term rates being either the same as or lower
than short-term rates during this period, the Company's investments shifted
toward short-term investments, ending the year 2000 with an increase in
short-term investments compared to year-end 1999.

         The increase in the Company's total investments was also positively
affected by an increase in the market value of its securities available for sale
portfolio. The net unrealized gains on the Company's securities available for
sale portfolio increased $6.3 million to $10.0 million at December 31, 2000 from
$3.7 million at December 31, 1999. The increase in market value of the
securities portfolio is directly related to the upward movement in bond prices.

         The loan portfolio at December 31, 2000, net of allowance for loan
losses, amounted to $307.5 million compared to $322.8 million at December 31,
1999, a decrease of $15.3 million or 4.7%. This decrease resulted primarily from
a decrease in fixed rate residential mortgage loans. The rising interest rates
in the first half of 2000 significantly reduced the demand for mortgage
refinancings. As a result, total loan originations decreased to $33.0 million in
2000, from $82.4 million the prior year. Loan origination totals for 1999
include a $15.0 million commercial loan to a single borrower with AAA rated
credit.

         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. Total deposits increased a modest $5.6 million
during 2000 to $823.6 million at December 31, 2000, from $818.0 at year-end
1999.

         Total stockholders' equity increased $6.7 million to $108.2 million at
December 31, 2000, representing a book value of $34.25 per share, from $101.5
million representing a book value of $30.65 per share at December 31, 1999. This
represents an increase in book value per share of $3.60 or 11.7% over the prior
year. Contributing to the increase in total stockholders' equity was the
Company's net income of $11.1 million in 2000, an increase in net unrealized
gains, net of tax, on the Company's securities available for sale of $4.0
million and the issuance of common stock under the Company's stock option plan.
These were partially offset by the payment of $3.8 million in dividends to
stockholders and the cost of shares of treasury stock repurchased during the
year in the amount of $5.8 million. The Company's book value per share was
positively affected by the Company's purchase of 191,100 shares of its common
stock, at less than current book value, during 2000 pursuant to its stock
repurchase program.


                                                                              13

ASSET QUALITY

Asset quality remains strong. Nonaccrual loans, generally those loans which are
90 days or more delinquent, decreased to $0.6 million at December 31, 2000, from
$0.9 million at December 31, 1999. The bank's provision for loan losses, which
amounted to $140 thousand in 1999, decreased by $80 thousand to $60 thousand in
2000. Loan charge-offs, net of recoveries, amounted to $21 thousand in 2000,
down from $35 thousand in 1999, which continued the trend of recent years.

         The Bank added a modest $39 thousand to its allowance for loan losses
in 2000 due to a low level of net loan charge-offs and the high quality of its
loan portfolio. The bank's allowance for loan losses at December 31, 2000
totaled approximately $2.6 million, representing 459% of nonaccrual loans and
0.84% 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 had no real estate acquired through foreclosure at year-end
2000.


RESULTS OF OPERATIONS

Comparison of the years 2000 and 1999

Massbank Corp. reported consolidated net income of $11.1 million or $3.37 in
diluted earnings per share in 2000 compared to net income of $11.3 million or
$3.25 in diluted earnings per share in 1999. This is the ninth consecutive year
of record diluted earnings per share for the Company. Basic earnings per share
for 2000 increased to $3.45 from $3.35 in the prior year. Return on average
assets and return on average realized equity were 1.20% and 10.95%,
respectively, in 2000, compared to 1.20% and 11.35%, respectively, in 1999.

         The Company reported operating net income of $11.3 million or $3.43 in
diluted operating earnings per share ($3.51 in basic operating earnings per
share) for the year ended December 31, 2000. This compares to operating net
income of $11.3 million or $3.25 in diluted operating earnings per share ($3.35
in basic operating earnings per share) earned in 1999. The Company's operating
net income for the year ended December 31, 2000 excludes $363,000 of net
litigation expenses (pre-tax) or $211,000 (after tax) incurred in connection
with Massbank's prosecution of a trademark case. The Company was successful in
protecting its trademarks against infringement by another financial institution
and was granted some compensation for legal fees in the final judgement.

         The decrease in net income in 2000 compared to 1999 primarily reflects
a decrease in securities gains of $508 thousand, a decrease in net interest
income of $119 thousand and a decrease in non-interest income (exclusive of
securities gains) of $66 thousand. These were partially offset by a decrease in
the provision for loan losses of $80 thousand, a decrease in non-interest
expense of $53 thousand and the Company's lower effective income tax rate.
Additionally, the earnings per share increase in 2000 was positively effected by
the reduced number of average common shares outstanding as a result of the
Company's purchase of 191,100 shares of its common stock during 2000 pursuant to
its stock repurchase program.


NET INTEREST INCOME

Net interest income on a fully taxable equivalent basis totaled $25.0 million
for 2000 and $25.1 million for 1999. This decrease was principally attributable
to a decrease in average earning assets, partially offset by an improvement in
net interest margin. Average earning assets decreased $17.0 million to $905.7
million in 2000, from $922.7 million in 1999. The Company's net interest margin
for 2000 was 2.76%, an improvement from 2.72% reported in 1999.

         The tables on pages 22 and 23 set forth, among other things, the extent
to which changes in interest rates and changes in the average balances of
interest-earning assets and interest-bearing liabilities have effected interest
income and expense during the years indicated. For each category of
interest-earning assets and interest-bearing liabilities, information is
provided on changes due to (1) changes in volume and (2) changes in interest
rates.


INTEREST AND DIVIDEND INCOME

Interest and dividend income on a fully taxable equivalent basis totaled $60.4
million for the year ended December 31, 2000, compared to $58.3 million for the
year ended December 31, 1999. The yield on average earning assets increased to
6.67% in 2000, from 6.32% in the prior year. The average total earning assets of
the Company decreased $17.0 million in 2000.

         As shown in the rate/volume analysis table on page 23, the improvement
in yield on average earning assets resulted in an increase in interest and
dividend income in 2000 of $3.1 million over 1999. Conversely, the total effect
of lower average earning assets on interest and dividend income in 2000 was a
$1.0 million decrease from 1999, resulting in a net increase in total interest
and dividend income of $2.1 million over 1999.

INTEREST EXPENSE

Total interest expense increased $2.2 million or 6.6% to $35.4 million for the
year ended December 31, 2000 from $33.2 million for the year ended December 31,
1999. This increase is due to an increase in the Company's average cost of funds
from 4.02% in 1999 to 4.32% in 2000, partially offset by the decrease in
interest expense resulting from a decrease in the Company's average total
deposits, from $826.7 million in 1999 to $818.6 million in 2000.

         The Company's higher cost of funds in 2000 was the result of rising
market interest rates in 2000.

         As shown in the rate/volume analysis table on page 23, the effect on
total interest expense from changes in interest- bearing deposit rates was a
$2.5 million increase over 1999. Conversely, the total effect of lower average
total deposits on interest expense in 2000 was a $0.3 million decrease from
1999, resulting in a net increase in total interest expense of $2.2 million over
1999.


PROVISION FOR LOAN LOSSES

The provision for loan losses represents a charge against current earnings and
an addition to the allowance for loan losses. The provision for loan losses in
2000 was $60 thousand compared to $140 thousand in 1999. 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 SFAS 114, 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. At December 31, 2000, the
allowance for loan losses was $2.6 million representing 459% of nonaccrual
loans. The Bank's nonaccrual loans totaled $565 thousand at December 31, 2000
down from $857 thousand a year earlier. Net charge-offs also declined to $21
thousand in 2000 from $35 thousand in the prior year. Management believes that
the allowance for loan losses as of year-end 2000 is adequate to cover the risks
inherent in the loan portfolio under current conditions.


NON-INTEREST INCOME

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

         Non-interest income decreased $0.6 million to $5.0 million for the year
ended December 31, 2000, from $5.6 million for the year ended December 31, 1999.
This decrease is primarily due to a decrease in securities gains in 2000
compared to 1999.

         Net securities gains totaled $3.5 million in 2000 compared to $4.0
million in the prior year. The securities gains are primarily attributable to
the favorable performance of the Company's equity securities portfolio which has
produced strong returns in recent years. Management does not expect this trend
to continue. Management believes that the equity markets, which have corrected
in recent months, will provide returns in the future that represent more closely
the historical norms.

         All other non-interest income combined decreased $66 thousand to less
than $1.5 million in 2000, from over $1.5 million in the prior year. This
decrease is due to a decrease in deposit account service fees and miscellaneous
other non-interest income of $36 thousand and $30 thousand, respectively.


NON-INTEREST EXPENSE

Non-interest expense totaled $12.5 million for 2000, a decrease of $53 thousand
compared with $12.6 million in 1999. The Company's total non-interest expense in
2000 includes net litigation expenses of $363 thousand that the bank incurred in
connection with its trademark case. Excluding these litigation expenses,
non-interest expense would have decreased $416 thousand or 3.3% to $12.2 million
in 2000, from $12.6 million in the prior year.

         The decrease of $53 thousand in non-interest expense for the year ended
December 31, 2000 is primarily due to a decrease in salaries and employee
benefit expenses. Salaries and employee benefits, the largest component of
non-interest expense, decreased $436,000 or 5.9% to $7.0 million in 2000 from
$7.4 million in 1999. Part of this improvement resulted from the fact that the
bank operated with fewer people in 2000 due in part to the tight labor market in
Massachusetts. Offsetting this decrease was an increase of over 100% in
professional services expenses, from $481 thousand in 1999 to $959 thousand in
2000, due largely to the aforementioned litigation expenses that the bank
incurred in protecting its trademarks against infringement by another financial
institution.

         Excluding the aforementioned litigation expenses, the Company's
efficiency ratio, which measures how much it costs to generate one dollar of
revenue, showed modest improvement in 2000, reaching 40.5% from the previous
year's milestone of 40.9%.


                                                                              15

INCOME TAX EXPENSE

The Company recorded income tax expense of $6.2 million in 2000, a decrease of
$360 thousand when compared to the prior year. The decrease in income tax
expense is due primarily to lower pretax earnings and a reduction in the
Company's effective income tax rate. The effective income tax rate for the year
ended December 31, 2000 was 35.77%, down from 36.66% in the prior year. The
decrease in the Company's effective income tax rate in 2000 is due, in part, to
the increased investment income generated by the Bank's two security corporation
subsidiaries which are taxed at a lower rate than the Bank for state income tax
purposes.


RESULTS OF OPERATIONS

COMPARISON OF THE YEARS 1999 AND 1998

Massbank Corp. reported consolidated net income of $11.3 million or $3.35 in
basic earnings per share in 1999 compared to net income of $10.9 million or
$3.09 in basic earnings per share in 1998. This was the seventh consecutive year
of record net income for the Company. Diluted earnings per share for 1999
increased 9.4% to $3.25 from $2.97 in 1998.

         In 1999, the Company's return on average assets rose to a new high of
1.20% from 1.17% in the prior year. Return on average realized equity also
increased, from 11.08% in 1998 to 11.35% in 1999.

         Increases in both net income and earnings per share in 1999 compared to
1998 primarily reflect an increase in securities gains of $1.1 million, a
decrease in the provision for loan losses of $53 thousand and the Company's
lower effective income tax rate. These improvements were partially offset by a
decrease of $512 thousand in net interest income, a decrease of $168 thousand in
non-interest income (exclusive of securities gains) and an increase in
non-interest expense of $51 thousand. Additionally, the earnings per share
increase in 1999 was positively affected by the reduced number of average common
shares outstanding as a result of the Company's purchase of 210,967 shares of
its common stock during 1999 pursuant to its stock repurchase program.


NET INTEREST INCOME

Net interest income on a fully taxable equivalent basis totaled $25.1 million
for 1999 and $25.7 million for 1998. This decrease was principally attributable
to a decline in net interest margin, partially offset by the positive effect of
average earning asset growth. The net interest margin for 1999 was 2.72%, a
decline from 2.81% reported in 1998. The Company's average earning assets
increased $9.8 million to $922.7 million in 1999, from $912.9 million in 1998.

         The tables on pages 22 and 23 set forth, among other things, the extent
to which changes in interest rates and changes in the average balances of
interest-earning assets and interest-bearing liabilities have effected interest
income and expense during the years indicated. For each category of
interest-earning assets and interest-bearing liabilities, information is
provided on changes due to (1) changes in volume and (2) changes in interest
rates.


INTEREST AND DIVIDEND INCOME

Interest and dividend income on a fully taxable equivalent basis totaled $58.3
million for the year ended December 31, 1999, compared to $60.0 million for the
year ended December 31, 1998. The yield on average earning assets was 6.32% in
1999, down from 6.56% in the prior year. The average total earning assets of the
Company increased to $922.7 million in 1999, up $9.8 million from $912.9 million
in 1998.

         As shown in the rate/volume analysis table on page 23, the decline in
yield on average earning assets resulted in a decrease in interest and dividend
income in 1999 of $2.6 million from 1998. Conversely, the total effect of higher
average earning assets on interest and dividend income in 1999 was a $942
thousand increase over 1998, resulting in a net decrease in total interest and
dividend income of $1.6 million from 1998.


INTEREST EXPENSE

Total interest expense decreased $1.1 million or 3.3% to $33.2 million for the
year ended December 31, 1999 from $34.3 million for the year ended December 31,
1998. This decrease is due to a decline in the Company's average cost of funds
from 4.23% in 1998 to 4.02% in 1999, partially offset by the higher interest
expense resulting from an increase in the Company's average total deposits, from
$811.6 million in 1998 to $826.7 million in 1999.

         The Company's lower cost of funds in 1999 was the result of changes in
market interest rates and certain pricing strategies which the bank implemented
during the year.

         As shown in the rate/volume analysis table on page 23, the effect on
total interest expense from changes in interest- bearing deposit rates was a
$1.6 million decrease from 1998. Conversely, the total effect of higher average
total deposits on interest expense in 1999 was a $516 thousand increase over
1998, resulting in a net decrease in total interest expense of $1.1 million from
1998.

PROVISION FOR LOAN LOSSES

The provision for loan losses represents a charge against current earnings and
an addition to the allowance for loan losses. The provision for loan losses in
1999 was $140 thousand compared to $193 thousand in 1998. In determining the
amount to provide for loan losses, the key factor is the adequacy of the
allowance for loan losses. In making its decision, management considers a number
of factors, including the risk characteristics of the loan portfolio, underlying
collateral, current and anticipated economic conditions, and trends in loan
delinquencies and charge-offs. At December 31, 1999, the allowance for loan
losses was $2.6 million representing 321% of nonaccrual loans. The Banks
nonaccrual loans totaled $0.8 million at December 31, 1999 down from $1.0
million a year earlier. Net charge-offs also declined to $35 thousand in 1999
from $77 thousand in the prior year. Management believes that the allowance for
loan losses as of year-end 1999 is adequate to cover the risks inherent in the
loan portfolio under current conditions.


NON-INTEREST INCOME

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

         Non-interest income increased to $5.6 million for the year ended
December 31, 1999, from $4.6 million for the year ended December 31, 1998. This
improvement is due to an increase in securities gains in 1999 compared to 1998.

         Net securities gains totaled $4.0 million in 1999 compared to $2.9
million in the prior year. This increase is primarily attributable to the
favorable performance of the Company's equity securities portfolio which has
produced strong returns over the past five years. Management believes the equity
markets will return to levels which represent more closely the historical norms
than has recently been the case, and does not anticipate the trend of recent
years gains to continue.

         All other non-interest income combined decreased $168 thousand to $1.5
million in 1999 from $1.7 million in the prior year, due to a decrease in
deposit account service fees and other non-interest income of $87 thousand and
$81 thousand, respectively.


NON-INTEREST EXPENSE

Non-interest expense totaled $12.6 million for 1999, compared with $12.5 million
in 1998. Expenses increased by only $51 thousand in 1999, due to the Company's
cost containment efforts and the reasons summarized below:

         Salaries and employee benefits expenses increased by only $10 thousand
to $7.4 million in 1999 compared to 1998. Annual merit increases and the
slightly higher costs of employee benefits were partly offset by staff
reductions and a decrease of $96 thousand in the Company's Employee Stock
Ownership Plan ("ESOP") expense. The ESOP expense is tied closely to the average
market price of the Company's common stock which declined during 1999. Also
contributing to the slight increase in salaries and employee benefits expenses
was a decrease of $41 thousand in loan origination related salary expenses being
deferred (and amortized over the life of the loans) due to a decrease in
residential lending activity in 1999 compared to 1998.

         Occupancy and equipment expense increased by 4.2% or $87 thousand to
$2.1 million in 1999. This increase reflects higher depreciation expense due to
the building and leasehold improvements completed in 1998 and 1999, and an
increase in real estate tax expense in 1999, due partly to the larger dollar
amount of real estate tax abatements received in 1998 compared to 1999.

         All other non-interest expenses combined consisting of data processing,
professional services, advertising and marketing, amortization of intangibles,
deposit insurance, contributions and other expenses remained relatively flat,
decreasing $46 thousand in 1999 compared to 1998.

         The bank's efficiency ratio, which measures how much it costs to
generate one dollar of revenue, continued its steady improvement of the past
several years, reaching 40.9% in 1999.



                                                                              17

INCOME TAX EXPENSE

The Company recorded income tax expense of $6.5 million in 1999, an increase of
$65 thousand when compared to the prior year. The increase in income tax expense
is due primarily to higher pretax earnings partially offset by a slight
reduction in the Company's effective income tax rate. The effective income tax
rate for the year ended December 31, 1999 was 36.66%, down from 37.26% in the
prior year. The decrease in the Company's effective income tax rate in 1999 is
due, in part, to the scheduled reduction in the Bank's statutory state excise
tax rate from 10.91% in 1998 to 10.50% in 1999; and to the increased investment
income generated by the Bank's two security corporation subsidiaries which are
taxed at a lower rate than the Bank for state income purposes.


LIQUIDITY AND CAPITAL RESOURCES

The Bank must maintain a sufficient level 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 amortization and prepayments, sales or maturities of investment securities
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 December 31, 2000, the Bank had $112.7 million or 12.0% of total
assets and $155.4 million or 16.6% of total assets invested, respectively, in
overnight federal funds sold and United States obligations.

         The Bank is a Federal Deposit Insurance Corporation insured institution
subject to the FDIC regulatory capital requirements. The FDIC regulations
require all FDIC insured institutions to maintain minimum levels of Tier I
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
I capital to total average 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
I 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 capital components include supplemental
capital components such as qualifying allowance for loan losses, qualifying
subordinated debt and up to 45 percent of the pretax 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 December 31, 2000, the Bank had a leverage
Tier I capital to average assets ratio of 10.89%, a Tier I capital to
risk-weighted assets ratio of 34.14% and a total capital to risk-weighted assets
ratio of 35.86%. The Company, on a consolidated basis, had ratios of leverage
Tier I capital to average assets of 10.94%, Tier I capital to risk-weighted
assets of 34.30% and total capital to risk-weighted assets of 36.02% at December
31, 2000.


ASSET AND LIABILITY MANAGEMENT

The goal of asset/liability management is to ensure that liquidity, capital and
market risk are prudently managed. Asset/ liability management is governed by
policies reviewed and approved annually by the Bank's Board of Directors (the
"Board"). The Board establishes policy limits for long-term interest rate risk
assumption and delegates responsibility for monitoring and measuring the
Company's exposure to interest rate risk to the Risk Management and
Asset/Liability Committee (the"Committee"). The Committe which is comprised of
members of the Company's Board of Directors, members of senior management and
the bank's comptroller, generally meets three times a year to review the
economic environment and the volume, mix and maturity of the Company's assets
and liabilities.

INTEREST RATE RISK

The primary goal of interest-rate risk management is to control the Company's
exposure to interest rate risk both within limits approved by the Board and
within narrower guidelines approved by the Risk Management and Asset/Liability
Committee. These limits and guidelines reflect the Company's tolerance for
interest rate risk over both short-term and long-term time horizons.
The Company monitors its interest rate exposures using a variety of financial
tools. It also produces a GAP analysis quarterly, reflecting the known or
assumed maturity, repricing and other cash flow characteristics of the Company's
interest-earning assets and interest-bearing liabilities.

         Interest rate risk materializes in two forms, market value risk and
reinvestment risk.

         Financial instruments calling for future cash flows show market value
increases or decreases when rates change. Management monitors the potential
change in market value of the Company's debt securities assuming an immediate
(parallel) shift in interest rates of up to 200 basis points up or down. Results
are calculated using industry standard modeling analytics and securities data
from The Bloomberg. The Company uses the results to review the potential changes
in market value resulting from immediate rate shifts and to manage the effect of
market value changes on the Company's capital position.

         Reinvestment risk occurs when an asset and the liability funding the
asset do not reprice and/or mature at the same time. The difference or mismatch
with respect to repricing frequency and/or maturity is a risk to net interest
income.

         Complicating management's efforts to control the Company's exposure to
interest rate risk is the fundamental uncertainty of the maturity, repricing
and/or runoff characteristics of a significant portion of the Company's assets
and liabilities. This uncertainty often reflects optional features embedded in
these financial instruments. The most important optional features are embedded
in the Company's deposits, loans and mortgage-backed securities.

         For example, many of the Company's interest-bearing deposit products
(e.g., savings, money market deposit accounts and NOW accounts) have no
contractual maturity. Customers have the right to withdraw funds from these
deposit accounts freely. Deposit balances may therefore run off unexpectedly due
to changes in competitive or market conditions. In addition, when market
interest rates rise, customers with time certificates of deposit ("CDs") often
pay a penalty to redeem their CDs and reinvest at higher rates. Given the
uncertainties surrounding deposit runoff and repricing, the interest rate
sensitivity of the Company's liabilities cannot be determined precisely.

         Similarly, customers have the right to prepay loans, particularly
residential mortgage loans, usually without penalty. As a result, the Company's
mortgage based assets (i.e., mortgage loans and mortgage-backed securities) are
subject to prepayment risk. This risk tends to increase when interest rates fall
due to the benefits of refinancing. Since the future prepayment behavior of the
Company's customers is uncertain, the interest rate sensitivity of mortgage
based assets cannot be determined exactly.

         Management monitors and adjusts the difference between the Company's
interest-earning assets and interest-bearing liabilities repricing within
various time frames ("GAP position").

         GAP analysis provides a static view of the maturity and repricing
characteristics of the Company's balance sheet positions. The interest rate GAP
is prepared by scheduling all interest-earning assets and interest-bearing
liabilities according to scheduled or anticipated repricing or maturity. The GAP
analysis identifies the difference between an institution's assets and
liabilities that will react to a change in market rates. GAP analysis theory
postulates that if the GAP is positive and rates increase, the institution's net
interest spread will increase as more assets than liabilities react to the rate
change. If the GAP is negative, more liabilities than assets will react to a
change in market rates. If rates rise, the institution's net interest spread
will fall as more liabilities react to market rates than assets.

         In contrast, however, the Company's one-year GAP position while
positive as of year end 2000 has been negative in recent years and its net
interest spread has moved in the same direction as the change in market rates
rather than in the opposite direction as GAP analysis theory postulates. One of
the more significant reasons for this is the fact that a GAP presentation does
not reflect the degrees to which interest earning assets and deposit costs
respond to changes in market interest rates. The rates on all financial
instruments do not always move by the same amount as the general change in
market rates. In addition, the Company has elected, in recent years, either not
to raise rates or to raise rates by a modest amount on its savings and
transaction-oriented accounts in response to an increase in market rates. It
should be noted that for the above two reasons, among others, the Company's net
interest spread has moved in the same direction as market interest rates in the
past and may in the future.



                                                                              19

INTEREST RATE RISK (CONTINUED)

         The Company's policy is to limit its one-year GAP position to 15.0% of
total assets. The Company has historically managed its interest rate GAP
primarily by lengthening or shortening the maturity structure of its securities
portfolio, by continually modifying the composition of its securities portfolio
and by selectively pricing and marketing its various deposit products.

         The following table summarizes the Company's GAP position at December
31, 2000. As of this date, the Company's one-year cumulative GAP position was
positive $33.4 million, or approximately 3.6% of total assets. The cumulative
GAP-asset ratio measures the direction and extent of imbalance between an
institution's assets and liabilities repricing through the end of a particular
period.

         The Company uses certain assumptions to estimate fair values and
expected maturities. For interest-sensitive assets, expected maturities are
based upon contractual maturity, and projected repayments and prepayments of
principal. For interest-sensitive deposit liabilities, maturities are based on
contractual maturity and estimated deposit runoff based on the Bank's own
historical experience. The actual maturity of the Company's financial
instruments could vary significantly from what has been presented in the above
table if actual experience differs from the assumptions used.

OTHER MARKET RISKS

The Company's investment securities portfolio includes equity securities with a
market value of approximately $19.8 million at December 31, 2000. The net
unrealized gains on these securities totaled $5.4 million at year-end 2000.
Movements in equity prices may effect the amount of securities gains or losses
which the Company realizes from the sale of these securities and thus may have
an impact on earnings.

RATE/VOLUME ANALYSIS

The following table presents, for the years indicated, the changes in interest
and dividend income and the changes in interest expense attributable to changes
in interest rates and changes in the volume of earning assets and
interest-bearing liabilities. A change attributable to both volume and rate has
been allocated proportionately to the change due to volume and the change due to
rate.

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.


RECENT ACCOUNTING PRONOUNCEMENTS

ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standard ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS No. 138, "Accounting for
Certain Derivative Instruments and Certain Hedging Activities." These Statements
establish comprehensive accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, (collectively referred to as derivatives) and for hedging activities.
They require that an entity recognize all derivatives as either assets or
liabilities in its balance sheet and measure those instruments at fair market
value. Under these Statements, an entity that elects to apply hedge accounting
is required to establish at the inception of the hedge the method it will use
for assessing the effectiveness of the hedging derivative and the measurement
approach for determining the ineffective aspect of the hedge. The Company
adopted these Statements on January 1, 2001. The adoption of these Statements
did not have a material effect on the Company's consolidated financial
statements.

INDEPENDENT AUDITORS' REPORT

[KPMG LOGO]

The Board of Directors and Stockholders
Massbank Corp.:

         We have audited the accompanying consolidated balance sheets of
Massbank Corp. and subsidiaries as of December 31, 2000 and 1999, and the
related consolidated statements of income, changes in stockholders' equity and
cash flows for each of the years in the three-year period ended December 31,
2000. These consolidated financial statements are the responsibility of the
Company'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 auditing standards generally
accepted in the United States of America. 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 financial position of Massbank
Corp. and subsidiaries at December 31, 2000 and 1999, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 2000, in conformity with accounting principles generally
accepted in the United States of America.

MASSBANK CORP. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2000, 1999 AND 1998

1.        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Massbank Corp. (the "Company") is a Delaware chartered holding company whose
principal subsidiary is Massbank (the "Bank"). The Bank operates fifteen full
service banking offices in Reading, Melrose, Stoneham, Wilmington, Medford,
Chelmsford, Tewksbury, Westford, Dracut, Lowell and Everett providing a variety
of deposit, lending and trust services. As a Massachusetts chartered savings
bank whose deposits are insured by the Federal Deposit Insurance Corporation
("FDIC") and the Depositors Insurance Fund ("DIF"), the activities of the Bank
are subject to regulation, supervision and examination by federal and state
regulatory authorities, including, but not limited to the FDIC, the
Massachusetts Commissioner of Banks and the DIF. In addition, as a bank holding
company, the Company is subject to supervision, examination and regulation by
the Board of Governors of the Federal Reserve System.


BASIS OF PRESENTATION

The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiary Massbank and its subsidiaries: Readibank Properties,
Inc., Readibank Investment Corporation and Melbank Investment Corporation.

         The Company has one reportable operating segment. All significant
intercompany balances and transactions have been eliminated in consolidation.
The accounting and reporting policies of the Company conform to generally
accepted accounting principles and to general practices within the banking
industry. In preparing the consolidated 1/2nancial statements, management is
required to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the balance sheet date and income and expenses for the
period. Material estimates that are particularly susceptible to change in the
near term relate to the determination of the allowance for loan losses.

         Certain amounts in the prior years' consolidated financial statements
were reclassified to permit comparison with the current fiscal year.


INVESTMENTS IN DEBT AND EQUITY SECURITIES

Under its investment policy, management determines the appropriate
classification of securities at the time of purchase. Those debt securities that
the Company has the intent and the ability to hold to maturity are classified as
securities held to maturity and are carried at amortized historical cost. Those
securities held for indefinite periods of time and not intended to be held to
maturity are classified as available for sale. Securities held for indefinite
periods of time include securities that management intends to use as part of its
asset/liability management strategy and that may be sold in response to changes
in market conditions, interest rates, changes in prepayment risk, the need to
increase regulatory capital and other factors. The Company records investment
securities available for sale at aggregate market value with the net unrealized
holding gains or losses reported, net of tax effect, as a separate component of
stockholders' equity until realized. As of December 31, 2000, stockholders'
equity included approximately $6.0 million, representing the net unrealized
gains on securities available for sale, less applicable income taxes.
Investments classified as trading securities are stated at market value with
unrealized gains and losses included in earnings.

         Income on debt securities is accrued and included in interest and
dividend income. The specific identification method is used to determine
realized gains or losses on sales of securities available for sale which are
also reported in non-interest income under the caption "gains on securities."
When a security suffers a loss in value which is considered other than
temporary, such loss is recognized by a charge to earnings.


DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standard ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities", as amended by SFAS No. 138, "Accounting for
Certain Derivative Instruments and Certain Hedging Activities." These Statements
establish comprehensive accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, (collectively referred to as derivatives) and for hedging activities.
They require that an entity recognize all derivatives as either assets or
liabilities in its balance sheet and measure those instruments at fair market
value. Under these Statements, an entity that elects to apply hedge accounting
is required to establish at the inception of the hedge the method it will use
for assessing the effectiveness of the hedging derivative and the measurement
approach for determing the ineffective aspect of the hedge. The Company adopted
these Statements on January 1, 2001. The adoption of these Statements did not
have a material effect on the Company's consolidated financial statements.



                                                                              31

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

LOANS

Loans are reported at the principal amount outstanding, net of unearned fees.
Loan origination fees and related direct incremental loan origination costs are
offset and the resulting net amount is deferred and amortized over the life of
the loan using the level-yield method.

         The Bank generally does not accrue interest on loans which are 90 days
or more past due. When a loan is placed on nonaccrual status, all interest
previously accrued but not collected is reversed from income and all
amortization of deferred loan fees is discontinued. Interest received on
nonaccrual loans is either applied against principal or reported as income
according to management's judgment as to the collectibility of principal.
Interest accruals are resumed on such loans only when they are brought current
with respect to interest and principal and when, in the judgment of management,
the loans are estimated to be fully collectible as to both principal and
interest.

         Impairment on loans for which it is probable that the creditor will be
unable to collect all amounts due according to the contractual terms of the loan
agreement are measured on a discounted cash flow method, or at the loan's
observable market price, or at the fair value of the collateral if the loan is
collateral dependent. However, impairment must be measured based on the fair
value of the collateral if it is determined that foreclosure is probable.
Impaired loans consist of all nonaccrual commercial loans.


ALLOWANCE FOR LOAN LOSSES

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 SFAS 114, 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.


PREMISES AND EQUIPMENT

Land is carried at cost. Premises, equipment and leasehold improvements are
stated at cost, less accumulated depreciation and amortization computed
primarily by use of the straight-line method over the estimated useful lives of
the related assets or terms of the related leases.


REAL ESTATE ACQUIRED THROUGH FORECLOSURE

Real estate acquired through foreclosure is comprised of foreclosed properties
where the Bank has actually received title and loans determined to be
substantially repossessed. Real estate loans that are substantially repossessed
include only those loans for which the Bank has taken possession of the
collateral but has not completed legal foreclosure proceedings. Loan losses
arising from the acquisition of such properties are charged against the
allowance for loan losses. Real estate acquired through foreclosure is recorded
at the lower of the carrying value of the loan or the fair value of the property
constructively or actually received, less estimated costs to sell the property
following foreclosure. Operating expenses and any subsequent provisions to
reduce the carrying value to fair value are charged to current period earnings.
Gains or losses upon disposition are reflected in earnings as realized.


STOCK-BASED COMPENSATION

On January 1, 1996, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation." The
Statement establishes financial accounting and reporting standards for
stock-based compensation plans. SFAS No. 123 encourages, but does not require, a
fair value based method of accounting for stock-based compensation plans. The
Statement allows an entity to continue to measure compensation cost for those
plans using the intrinsic value based method prescribed by Accounting Principles
Board ("APB") Opinion No. 25. For those entities electing to use the intrinsic
value based method, SFAS No. 123 requires pro forma disclosures of net income
and earnings per share computed as if the fair value based method had been
applied. The Company continues to account for stock-based compensation costs
under APB Opinion No. 25.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

GOODWILL AND OTHER INTANGIBLES

The excess of purchase price over the fair value of net assets of acquired
companies is classified and reported as goodwill. Goodwill is being amortized
using the straight-line method, over 15 years. The deposit acquisition premium
arising from acquisitions is reported net of accumulated amortization. Such
premium is being amortized on a straight-line basis over 10 years. Goodwill and
other intangible assets are reviewed for possible impairment when it is
determined that events or changed circumstances may affect the underlying basis
of the asset.


PENSION PLAN

The bank accounts for pension benefits on the net periodic pension cost method
for financial reporting purposes. This method recognizes the compensation cost
of an employee's pension benefit over that employee's approximate service
period. Pension costs are funded in the year of accrual using the aggregate cost
method.


EMPLOYEES' STOCK OWNERSHIP PLAN ("ESOP")

The Company recognizes compensation cost equal to the fair value of the ESOP
shares committed to be released. Dividends on unallocated ESOP shares are
reported as a reduction of accrued interest on the ESOP loan. The Company
reports loans from outside lenders to its ESOP as a liability on its balance
sheet and reports interest cost on the debt. For earnings per share (EPS)
computations, ESOP shares that have been committed to be released are considered
outstanding. ESOP shares that have not been committed to be released are not
considered outstanding.


EARNINGS PER COMMON SHARE

Basic EPS is computed
by dividing net income by the weighted average number of shares of common stock
outstanding during the year reduced by the weighted average number of
unallocated shares held by the Employee Stock Ownership Plan ("ESOP"). Diluted
EPS reflects the effect on the weighted average shares outstanding of the number
of additional shares outstanding if dilutive stock options were converted into
common stock using the treasury stock method.

         The treasury shares acquired in connection with the Company's directors
deferred compensation plan are considered outstanding in the computation of
earnings per share and book value per share.

         A reconciliation of the weighted average shares outstanding for the
years ended December 31, 2000, 1999 and 1998 follows:

COMPREHENSIVE INCOME

Comprehensive income is defined as "the change in equity of a business
enterprise during a period from transactions and other events and circumstances
from non-owner sources." It includes all changes in equity during a period
except those resulting from investments by and distributions to shareholders.
The term "comprehensive income" describes the total of all components of
comprehensive income including net income.

         The Company's other comprehensive income and related tax effect for the
year ended December 31, 2000 and the year ended December 31, 1999 is as follows:

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

CASH AND CASH EQUIVALENTS

For purposes of reporting cash flows, cash and cash equivalents consist of cash
and due from banks, and short-term investments with original maturities of less
than 90 days.

         As a regulated financial institution, the Bank is required to maintain
certain reserve requirements of vault cash and/or deposits with the Federal
Reserve Bank of Boston. The amount of this reserve requirement, included in
"Cash and Due from Banks," was $8.7 million and $7.4 million at December 31,
2000 and 1999, respectively.


INCOME TAXES

The Bank recognizes income taxes under the asset and liability method. Under
this method, deferred tax assets and liabilities are established for the
temporary differences between the accounting basis and the tax basis of the
Bank's assets and liabilities at enacted tax rates expected to be in effect when
the amounts related to such temporary differences are realized or settled. The
Bank's deferred tax asset is reviewed and adjustments to such asset are
recognized as deferred income tax expense or benefit based upon management's
judgment relating to the realizability of such asset. Based on the Bank's
historical and current pretax earnings, management believes it is more likely
than not that the Bank will realize its existing gross deferred tax asset.


2. SHORT-TERM INVESTMENTS

Short-term investments consist of the following:

Maturities of mortgage-backed securities are based on contractual maturities
with scheduled amortization. Actual maturities will differ from contractual
maturities because borrowers may have the right to prepay obligations with or
without prepayment penalties.

5. LOANS

The Bank's lending activities are conducted principally in the local communities
in which it operates banking offices, and to a lesser extent, in selected areas
of Massachusetts and southern New Hampshire.

         The Bank offers single family and multi-family residential mortgage
loans and a variety of consumer loans. The Bank also offers mortgage loans
secured by commercial or investment property such as apartment buildings and
commercial or corporate facilities; loans for the construction of residential
homes, multi-family properties and for land development; and business loans for
other commercial purposes. Most loans granted by the Bank are either
collateralized by real estate or guaranteed by federal or local governmental
authorities. The ability of single family residential and consumer borrowers to
honor their repayment commitments is generally dependent on the level of overall
economic activity within the borrowers' geographic areas. The ability of
commercial real estate and commercial loan borrowers to honor their repayment
commitments is generally dependent on the economic health of the real estate
sector in the borrowers' geographic areas and the overall economy.


                                                                              37

An integral component of the Company's risk management process is to ensure the
proper allocation of the allowance for loan losses based upon an analysis of
risk characteristics, demonstrated losses and other factors. The unallocated
component of the allowance for loan losses represents management's view that
given the complexities of the loan portfolio, there are probable losses that
have been incurred within the portfolio but have not yet been specifically
identified. The unallocated portion of the allowance for loan losses is based on
management's assessment of many factors including the risk characteristics of
the loan 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. The unallocated portion of the allowance for loan
losses may change periodically after evaluating factors impacting assumptions
utilized in the calculation of the allocated portion of the allowance for loan
losses.

8. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

The Bank is party to financial instruments with off-balance sheet risk in the
normal course of business to meet the financing needs of its customers and to
reduce its own exposure to fluctuations in interest rates. These financial
instruments include commitments to extend credit and involve, to varying
degrees, elements of credit risk in excess of the amount recognized in the
consolidated balance sheet. The contract or notional amounts reflect the extent
of involvement the Bank has in particular classes of these instruments. The
Bank's exposure to credit loss in the event of nonperformance by the other party
to the financial instrument is represented by the contractual or notional amount
of those instruments. The Bank uses the same credit policies in making
commitments and conditional obligations as it does for on-balance sheet
instruments.



- ----------------------------------------------------------------------------------------------
                                                                   CONTRACT OR NOTIONAL AMOUNT

- ----------------------------------------------------------------------------------------------
                                                                                 
Financial instruments whose contract amounts represent credit risk:
  Commitments to originate residential mortgage loans                        $ 1,920   $ 2,829
  Unadvanced portions of construction loans                                      421        65
  Unused credit lines, including unused portions of equity lines of credit    30,918    31,693
==============================================================================================


Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Commitments
generally have fixed expiration dates or other termination clauses and may
require payment of a fee by the customer. Since many of the commitments are
expected to expire without being drawn upon, the total commitment amounts do not
necessarily represent future cash requirements. The Bank evaluates each
customer's credit-worthiness on a case-by-case basis. The amount of collateral
obtained, if any, is based on management's credit evaluation of the borrower.

11. FAIR VALUE OF FINANCIAL INSTRUMENTS

SFAS No. 107, "Disclosures about Fair Value of Financial Instruments," requires
that the Bank disclose estimated fair values for its financial instruments. Fair
value estimates, methods, and assumptions are set forth below for the Bank's
financial instruments.

CASH AND DUE FROM BANKS, SHORT-TERM INVESTMENTS AND ACCRUED INTEREST RECEIVABLE
The carrying amounts for these financial instruments approximate fair value
because of the short-term nature of these financial instruments.

INTEREST-BEARING DEPOSITS IN BANKS AND TERM FEDERAL FUNDS SOLD
The carrying amounts of the interest-bearing deposits in banks and term federal
funds sold reported in the balance sheet at December 31, 2000 and 1999
approximate fair value.

SECURITIES
The fair value of investment securities is estimated based on bid prices
published in financial newspapers or bid quotations received from securities
dealers.

         Statement 107 specifies that fair values should be calculated based on
the value of one unit without regard to any premium or discount that may result
from concentrations of ownership of a financial instrument, possible tax
ramifications, or estimated transaction costs.

         The carrying amount and estimated fair values of the Company's
investment securities are as follows:

===============================================================================

LOANS
Fair values are estimated for portfolios of loans with similar financial
characteristics. Loans are segregated by type such as residential mortgage,
commercial real estate, consumer and commercial.

         The fair values of residential and commercial real estate, and certain
consumer loans are calculated by discounting scheduled cash flows through the
estimated maturity using estimated market discount rates that reflect the credit
and interest rate risk inherent in the loan. The estimate of maturity is based
on the Bank's historical experience with repayments for each loan
classification, modified, as required, by an estimate of the effect of current
economic and lending conditions. For variable rate commercial loans and certain
variable rate consumer loans, including home equity lines of credit, carrying
value approximates fair value. Assumptions regarding credit risk, cash flows,
and discount rates are judgmentally determined using available market
information.

         The following table presents information for loans:

11. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

DEPOSITS
Under Statement 107, the fair value of deposits with no stated maturity, such as
demand deposits, NOW accounts, regular savings and special notice accounts, and
money market accounts, is equal to the amount payable on demand as of December
31, 2000 and 1999. The fair value of certificates of deposit is based on the
discounted value of contractual cash flows. The discount rate is estimated using
the rates currently offered for deposits of similar remaining maturities.

==================================================================================================


The fair value estimates and the carrying amounts above do not include the
benefit that results from the low-cost funding provided by the deposit
liabilities compared to the cost of borrowing funds in the market.

COMMITMENTS TO EXTEND CREDIT
The fair value of commitments to extend credit is estimated using the fees
currently charged to enter into similar agreements, taking into account the
remaining terms of the agreements and the present creditworthiness of the
counterparties. For fixed rate loan commitments, fair value also considers the
difference between current levels of interest rates and the committed rates.

         The Bank estimates the fair value of the cost to terminate commitments
to advance funds on construction loans and for residential mortgage loans in the
pipeline at December 31, 2000 and 1999 to be immaterial. Unused credit lines,
including unused portions of equity lines of credit, are at floating interest
rates and therefore there is no fair value adjustment.

LIMITATIONS
Fair value estimates are made at a specific point in time, based on relevant
market information and information about the financial instrument. These
estimates do not reflect any premium or discount that could result from offering
for sale at one time the Bank's entire holdings of a particular financial
instrument. Because no active market exists for a portion of the Bank's
financial instruments, fair value estimates are based on judgments regarding
future expected loss experience, current economic conditions, risk
characteristics of various financial instruments and other factors. These
estimates are subjective in nature and involve uncertainties and matters of
significant judgment and therefore cannot be determined with precision. Changes
in assumptions could significantly affect the estimates.

         Fair value estimates are based on existing on and off-balance sheet
financial instruments without attempting to estimate the value of anticipated
future business and the value of assets and liabilities that are not considered
financial instruments. For example, the Bank has a trust department that
contributes fee income annually. The trust department is not considered a
financial instrument, and its value has not been incorporated into the fair
value estimates. Other significant assets and liabilities that are not
considered financial assets or liabilities include deferred tax liabilities,
premises and equipment and goodwill. In addition, the tax ramifications related
to the realization of the unrealized gains and losses can have a significant
effect on fair value estimates and have not been considered in any of the
estimates.

12. INCOME TAXES (CONTINUED)

At December 31, 2000 and 1999, the Bank had gross deferred tax assets and gross
deferred tax liabilities as follows:

- ----------------------------------------------------------
(IN THOUSANDS) YEARS ENDED DECEMBER 31,      2000     1999
- ----------------------------------------------------------

  Other unrealized securities gains           109       93
  Other                                         1        4
- ----------------------------------------------------------
  Gross deferred tax liability              4,123    1,788
- ----------------------------------------------------------
Net deferred tax liability                 $2,418   $  199
==========================================================

         Based on the Company's historical and current pretax earnings,
management believes it is more likely than not that the Company will realize the
gross deferred tax asset existing at December 31, 2000. The primary sources of
recovery of the gross federal deferred tax asset are federal income taxes paid
in 2000, 1999 and 1998 that are available for carryback and the expectation that
the existing net deductible temporary differences will reverse during periods in
which the Company generates net taxable income. Since there is no carryback
provision for state income tax purposes, management believes the existing net
deductible temporary differences which give rise to the gross deferred state
income tax asset will reverse during periods in which the Company generates net
taxable income. There can be no assurance, however, that the Company will
generate any earnings or any specific level of continuing earnings.

         As a result of the Tax Reform Act of 1996, the special tax bad debt
provisions were amended to eliminate the reserve method. However, the tax effect
of the pre-1988 bad debt reserve amount of approximately $7.3 million remains
subject to recapture in the event that the Bank pays dividends in excess of its
reserves and profits.

14. STOCKHOLDERS' EQUITY

The Company may not declare or pay cash dividends on its shares of common stock
if the effect thereof would cause its stockholders' equity to be reduced below
or to otherwise violate legal or regulatory requirements. Substantially all of
the Company's retained earnings are unrestricted at December 31, 2000.

     The Bank is a Federal Deposit Insurance Corporation insured institution
subject to the FDIC regulatory capital requirements. The FDIC regulations
require all FDIC insured institutions to maintain minimum levels of Tier I
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
I capital to total average 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 new risk-based capital standards, FDIC insured institutions must maintain a
Tier I 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 new 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 capital
components include supplemental capital components such as qualifying allowance
for loan losses, qualifying subordinated debt and up to 45 percent of the pretax
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 Company and its principal subsidiary "Massbank"
set forth below currently exceed the minimum ratios for "well capitalized" banks
as defined by federal regulators.

15. EMPLOYEE BENEFITS

PENSION PLAN
The Bank sponsors a noncontributory defined benefit pension plan that covers all
employees who meet specified age and length of service requirements, which is
administered by the Savings Banks Employees Retirement Association ("SBERA").
The plan provides for benefits to be paid to eligible employees at retirement
based primarily upon their years of service with the Bank and compensation
levels near retirement. Contributions to the plan reflect benefits attributed to
employees' service to date, as well as services expected to be earned in the
future. Pension plan assets consist principally of government and agency
securities, equity securities (primarily common stocks) and short-term
investments.

         The following table sets forth the plan's funded status and amounts
recognized in the Company's consolidated financial statements for the plan years
ended October 31, 2000, 1999, and 1998, the plan's latest valuation dates:

PROFIT SHARING AND INCENTIVE COMPENSATION BONUS PLANS
The Bank's Profit Sharing and Incentive Compensation Bonus Plans provide for
payments to employees under certain circumstances based upon a year-end
measurement of the Company's net income and attainment of individual goals and
objec- tives by certain key officers. Payments of $302 thousand, $426 thousand
and $399 thousand were awarded under the plans in 2000, 1999 and 1998,
respectively.

EMPLOYEE STOCK OWNERSHIP PLAN
The Bank has an Employees' Stock Ownership Plan ("ESOP") for the benefit of each
employee who has completed at least 1,000 hours of service with the Company in
the previous twelve months. Under the plan, the ESOP has borrowed funds from a
third party bank to invest in the Company's common stock. As this obligation
will be liquidated primarily through future contributions to the ESOP by the
Bank, the obligation is reflected as a liability of the Company and a reduction
of stockholders' equity on the consolidated balance sheet. As of December 31,
2000 and 1999, such outstanding liabilities totaled $312 thousand and $468
thousand, respectively.

         Shares of the Company's common stock purchased with the loan proceeds
are held in a suspense account. As the loan is repaid, a proportionate number of
shares are released for allocation to plan participants. The shares are
allocated to plan participants annually, on a pro rata basis, based on
compensation.

         The ESOP acquired unallocated shares in 1986 when the plan was first
established and more recently in 1993. At December 31, 2000, the ESOP held
17,600 unallocated shares and 139,948 shares which have been allocated to
participants. The fair value of the unallocated shares at December 31, 2000 was
approximately $515 thousand.

         Dividends on unallocated shares are used to offset a portion of the
interest paid on the ESOP loan. Dividends on allocated shares held by the ESOP
are allocated to plan participants proportionately based on the number of shares
in the participant's allocated account.

         Total compensation and interest expense applicable to the ESOP amounted
to $289 thousand, $366 thousand and $462 thousand for the years ended December
31, 2000, 1999 and 1998, respectively.

EMPLOYEE AGREEMENTS
The Bank has entered into employment agreements with certain executive officers
which provide that the officer will receive a minimum amount of annual
compensation from the Bank for a specified period. The agreements also provide
for the continued payment of compensation to the officer for a specified period
after termination under certain circumstances, including if the officer's
termination follows a "change of control," generally defined to mean a person or
group attaining ownership of 25% or more of the shares of the Company.

EXECUTIVE SUPPLEMENTAL RETIREMENT AGREEMENTS
The Bank maintains executive supplemental retirement agreements for certain
executive officers. These agreements provide retirement benefits designed to
supplement benefits available through the Bank's retirement plan for employees.
Total expenses for benefits payable under the agreements amounted to $173
thousand, $139 thousand and $105 thousand in 2000, 1999 and 1998, respectively.

STOCK OPTION PLAN
Effective May 28, 1986, the Board of Directors of the Bank adopted a stock
option plan for the benefit of its officers and other employees. In January,
1991, the plan was amended to authorize the grant of options to non-employee
Directors of the Company. All but 5 of the 690,000 shares reserved for issuance
under the plan were issued. On April 19, 1994, shareholders approved and the
Bank adopted the Company's 1994 Stock Incentive Plan. The total number of shares
of common stock that can be issued under this plan is 360,000 shares. Both
incentive stock options and non-qualified stock options may be granted under the
plan. As of December 31, 2000, there were 135,010.7 non-qualified stock options
and 211,340.0 incentive stock options granted and outstanding to purchase shares
under the plans. The maximum option term is ten years. Further stock options may
be granted pursuant to the 1994 Stock Incentive Plan and will generally have an
exercise price equal to, or in excess of, the fair market value of a share of
common stock of the Company on the date the option is granted.

DIRECTORS DEFERRED COMPENSATION PLAN
In 1988, the Company established a deferred compensation plan for its directors.
The plan allows the Company's directors to defer receipt of all or a portion of
their compensation until the earlier of: (1) their attaining the age of 72, or
(2) their termination as a director of the Company. In 2000, the plan was
amended to allow the directors compensation to be invested in Company stock held
in an irrevocable trust. At December 31, 2000 the trust held 13,200 shares of
Massbank Corp. stock that the Company has classified as treasury stock. The
treasury shares are considered outstanding in the computation of earnings per
share and book value per share.

As discussed in Note 1, the Company has adopted SFAS No. 123 but continues to
account for its stock option plan using the intrinsic value based method
prescribed by APB Opinion No. 25. Accordingly, no compensation cost for this
plan has been recognized in the Consolidated Statements of Income for 2000.

         In determining the pro forma disclosures required by SFAS No. 123, the
fair value of each option grant is estimated on the date of grant using the
Black-Scholes option-pricing model. The following table presents pro forma net
income and earnings per share assuming the stock option plan was accounted for
using the fair value method prescribed by SFAS No. 123, the weighted average
assumptions used and the grant date fair value of options granted in 2000, 1999
and 1998:

16. SHAREHOLDER RIGHTS PLAN

On January 18, 2000, the Board of Directors adopted a new Shareholder Rights
Plan to replace the Company Plan that expired on January 16, 2000. In connection
with the adoption of the new Shareholder Rights Plan, the Board of Directors
authorized the issuance of one preferred stock purchase right for each share of
common stock of the Company outstanding as of January 19, 2000. Under the Plan,
the Rights initially are attached to and trade with the Company's shares of
common stock. Although the Rights are not exercisable initially, they separate
from the shares of common stock and become exercisable if a person becomes an
"acquiring person" by acquiring 11% or more of the Company's common stock or if
a person commences a tender offer that could result in that person owning 11% or
more of the common stock of Massbank Corp. In the event that a person becomes an
"acquiring person," each holder of a Right (other than the acquiring person)
would be entitled to acquire such number of shares of preferred stock which are
equivalent to Massbank common stock having a value of twice the exercise price
of the Right. The exercise price of a Right initially is $136.00 per one
one-thousandth of a share of the Company's preferred stock. If Massbank Corp. is
acquired in a merger or other business combination transaction after any such
event, each holder of a Right would be entitled to purchase, at the then-current
exercise price, shares of the acquiring company's common stock having a value of
twice the exercise price of the Right. The Rights will expire on January 19,
2010, but may be redeemed at the option of the Board of Directors for $0.01 per
Right at any time prior to the time at which any person becomes an acquiring
person or until the expiration date of the Shareholder Rights Plan.
