                      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 generally accepted accounting principles, 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, 1998
and December 31, 1997, and its operating results for the three and six months
ended June 30, 1998 and 1997.  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 year's consolidated financial statements
have been reclassified to permit comparison with the current fiscal year.  The
Company's per share information reported for the prior year has been restated 
to reflect the four-for-three stock split of the Company's common stock which 
was effected in the form of a stock dividend on September 15, 1997.

     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, 1997.

(2)  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.

(3)  Short-Term Investments
     Short-term investments consist of the following:

The investments above are stated at cost which approximates market value and 
have original maturities of 90 days or less.

(4)  Commitments
     At June 30, 1998, the Company had outstanding commitments to originate
mortgage loans and to advance funds for construction loans amounting to
$7,607,000 and commitments under existing home equity lines of credit and other
loans of approximately $23,963,000 which are not reflected on the consolidated
balance sheet.  In addition, as of June 30, 1998, the Company had a performance
standby letter of credit conveyed to others in the amount of $781,000 which is 
also not reflected on the consolidated balance sheet.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)


(5)  Reporting Comprehensive Income
     Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income".
SFAS 130 establishes standards for reporting and displaying comprehensive
income, which is defined as all changes to equity except investments by, and
distributions to, shareholders.  Net income is a component of comprehensive
income, with all other components referred to in the aggregate as other
comprehensive income.

     The Company's other comprehensive income and related tax effect for the
six months ended June 30, 1998 and the year ended December 31, 1997 is as
follows:

                          MANAGEMENT'S DISCUSSION & ANALYSIS OF
                      FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                      June 30, 1998


    The discussions set forth below and elsewhere herein contain certain
statements that may be considered forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of
the Securities Exchange Act of 1934, as amended.  A number of important factors
could cause actual results to differ materially from those in the forward-
looking statements.  Those factors include fluctuations in interest rates,
inflation, government regulations and economic conditions and competition in
the geographic and business areas in which the Company conducts its operations.

Results of Operations for the three months ended June 30, 1998


GENERAL
    For the quarter ended June 30, 1998, MASSBANK Corp. reported consolidated 
net income of $2,706,000 or $0.76 in basic earnings per share compared to net
income of $2,449,000, or $0.69 in basic earnings per share in the second
quarter of 1997.  This represents an increase of 10.5% in net income and a
10.1% increase in basic earnings per share.  Diluted earnings per share 
increased to $0.73 per share from $0.67 per share in last year's comparable
period, representing an increase of 9.0%.  The current and prior year per
share amounts reflect the four-for-three stock split of the Company's common
stock which was effected in the form of a stock dividend on September 15,
1997.

    The Company's improved earnings for the three months ended June 30, 1998 
resulted primarily from a decrease in non-interest expense.  Non-interest 
expense for the recent quarter decreased by $805,000 or 20.5% to $3,119,000 
from $3,924,000 for the same quarter last year.  This reduction was essentially
due to non-recurring expenses that the Bank incurred in the second quarter 1997
in conjunction with the establishment and endowment of a tax exempt private 
foundation; its acquisition of the Glendale Co-operative Bank; and a computer 
conversion.  The expense reduction is partially offset by an increase in income
tax expense.  This is essentially due to a non-recurring tax benefit of $260,000
that the Bank received in the 1997 second quarter as a result of having donated
appreciated securities to establish and endow the MASSBANK Charitable 
Foundation.

Net Interest Income
     Net interest income was $6.463 million for the second quarter of 1998 
compared to $6.462 million for the same period in 1997.  The net interest 
income for the recent quarter reflects the positive effect of earning asset
growth offset by the negative effect of a lower net interest margin.  The 
Company's average earning assets increased by $29.4 million or 3.3% to $908.5 
million in the second quarter of 1998, up from $879.1 million in the second 
quarter of the prior year.  The Company's net interest margin was 2.86% in the
recent quarter, down from 2.96% for the same quarter last year.

Interest and Dividend Income
     Interest and dividend income on a fully taxable equivalent basis for the
three months ended June 30, 1998, remained unchanged at $15.1 million when 
compared to the three months ended June 30, 1997.  The average total earning
assets of the Company increased by $29.4 million, as noted above.  The increase
in interest income resulting from the growth in earning assets in the recent
quarter, however, was offset by a decline in yield on earning assets.  As 
reflected in the table on page 13, the combination of yield declines in mortgage
loans, investment securities, federal funds sold and short-term investments,
partially offset by a modest increase in yield on other (consumer) loans,
resulted in an overall decline in yield on the Company's total average earning
assets of 23 basis points.  The weighted average yield on earning assets for
the second quarter of 1998 was 6.62% compared to 6.85% in the same quarter of
the prior year.  This decline in yield reflects a decrease in market interest
rates combined with a significant flattening of the yield curve.

Interest Expense
     Total interest expense for the three months ended June 30, 1998 was $8.5
million, remaining  essentially unchanged from the same quarter last year.  The
Company's average deposits, as shown in the table on page 14, increased $11.4
million or 1.4% to $808.1 million in the second quarter of 1998, up from $796.7
million in the second quarter of 1997.  The increase in interest expense
resulting from the growth in deposits in the recent quarter was offset by a 
decrease in average cost of funds.  The Company's average cost of funds for
the three months ended June 30, 1998 was 4.25%, down from 4.31% for the
comparable period in 1997.

Provision for Loan Losses
     The allowance for loan losses is increased by provisions charged to
operations based on management's assessment of many factors including the
risk characteristics of the portfolio, underlying collateral, current and
anticipated economic conditions that may affect 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
substantially 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.

    The provision for loan losses for the second quarter of 1998 was $45,000
versus $52,000 for the comparable period in 1997.  This decrease was 
essentially due to lower net loan charge-offs.  Loan charge-offs net of 
recoveries equalled $17,000 in the recent quarter, down from $27,000 for the
same quarter last year.

Provision for Loan Losses (continued)
     The reserve coverage as a percentage of the Bank's non-performing assets
declined slightly in the recent quarter.  At June 30, 1998, MASSBANK's 
allowance for loan losses totalled $2.405 million representing 131.9% of 
non-performing assets compared to $2.235 million representing 149.8% of 
non-performing assets at the end of the second quarter in 1997.

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

     Non-interest income for the second quarter of 1998 was $1,101,000, down
slightly from $1,136,000, for the comparable period in 1997.  The Company 
continues to benefit from the stock market's favorable performance.  The 
Company's equity portfolio has yielded substantial realized and unrealized 
gains.  Net unrealized gains in the equity securities portfolio totalled $9.8
million at June 30, 1998.  The Company reported net securities gains of $616,000
for the recent quarter compared to $610,000 for the same quarter last year.
Most of these gains were from the sale of equity securities.

Non-Interest Expense
     Non-interest expenses decreased by $805,000, or 20.5% to $3,119,000 in the
second quarter of 1998 from $3,924,000 in the second quarter of 1997.

     Salaries and employee benefits, the largest component of non-interest
expense, decreased by $81,000 or 4.1% from $1,955,000 in the second quarter of
1997 to $1,874,000 in the recent quarter.  This reduction is due largely to a
$70,000 decrease in the Company's directors deferred compensation plan expense.
The expense related to this plan is tied closely to the market value of the 
Company's common stock.  The increase in the market value of the Company's
common stock during the second quarter 1997, from $41.00 per share at March 31,
1997 to $47.75 per share at June 30, 1997, significantly increased the expense 
for the plan.  Conversely, the price of the Company's common stock in the recent
quarter declined from $50.125 per share at March 31, 1998 to $49.00 per share at
June 30, 1998, decreasing the expense for the plan.

     Occupancy and equipment expenses decreased from $516,000 in the second
quarter of 1997 to $472,000 in the second quarter of 1998.  This decrease is 
due essentially to real estate tax abatements that the Bank received in the
recent quarter.  These abatements were for both current and prior years and
totalled approximately $54,000.

     There were no merger and acquisition related expenses incurred in the 
second quarter of 1998.  In the second quarter of last year, the Bank incurred
merger and acquisition related expenses of $100,000 in connection with its
acquisition of the Glendale Co-operative Bank.

     Bank charitable contributions for the recent quarter were $6,000 compared
to $644,000 for the same quarter last year.  During the 1997 second quarter, 
the Company established and endowed a tax exempt private foundation -- the
"MASSBANK Charitable Foundation" -- for the purpose of making grants in future
years to benefit the Bank's local communities.  MASSBANK contributed appreciated
securities to the Foundation valued at $622,000 which is included in 
contributions expense for the second quarter of 1997.

Non-Interest Expense (continued)
     All other expenses combined, consisting of data processing, professional
services, advertising and marketing, amortization of intangibles, and other
expenses, increased by $58,000 or 8.2%, from $709,000 for the three months
ended June 30, 1997 to $767,000 for the three months ended June 30, 1998. 

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 provision for federal and state income taxes increased to $1,694,000 
for the three months ended June 30, 1998 from $1,173,000 for the same period 
in 1997.  The Company's combined effective income tax rate for the second
quarter of 1998 is 38.5% compared to 32.4% for the same quarter a year ago.

     The increase in effective income tax rate is essentially due to a non-
recurring tax benefit of approximately $260,000 that the Bank received last 
year as a result of having contributed appreciated securities to the MASSBANK
Charitable Foundation, as previously noted.

Results of Operations for the six months ended June 30, 1998

General
     For the six months ended June 30, 1998, the Company reported consolidated
net income of $5,540,000 or $1.56 in basic earnings per share ($1.50 per share
on a diluted basis) compared to net income of $4,922,000 or $1.39 in basic
earnings per share ($1.35 per share on a diluted basis) earned in the first half
of 1997.

     The Company's positive financial performance in the first six months of
1998 reflects a decrease in non-interest expense of $744,000 or 10.5%.  Non-
interest expense for the six months ended June 30, 1998 were $6,375,000 down
from $7,119,000 for the comparable period in 1997.  Additionally, the favorable
earnings results for the first half of 1998 reflect an improvement in net 
interest income due to growth in the Company's average earning assets.  Average
earning assets for the first half of 1998 increased to $907.8 million, up $30.7
million from the corresponding period in 1997.  Net interest income for the six
months ended June 30, 1998 was $13,035,000, up $162,000 when compared to the 
same period a year ago.

     The Company's earning results for the six months ended June 30, 1998 were
also impacted by the following factors:

    a)  Non-interest income increased by $317,000 to $2,347,000 in the first 
        six months of 1998 due to increased securities gains.

    b)  The Bank's provision for loan losses for the six months ended June 30,
        1998 decreased by 25% to $90,000 from $120,000 for the comparable period
        in 1997.

    c)  Income tax expense increased in the first half of 1998 compared to the
        same period in 1997.  This was partly due to a non-recurring tax benefit
        of approximately $260,000 that the Bank received in 1997 as a result of 
        having contributed appreciated securities to establish and endow the
        MASSBANK Charitable Foundation, as previously noted.

Net Interest Income
     Net interest income was $13.035 million for the six months ended June 30,
1998, up $162,000 from $12.873 million for the same period in 1997.  This 
increase resulted from the growth in the Company's interest-earning assets 
partially offset by a decrease in net interest margin.  The Company's net 
interest margin for the six months ended June 30, 1998 and 1997 was 2.89% 
and 2.95%, respectively.

     The Company's interest rate spread decreased to 2.39% for the first six
months of 1998, from 2.52% in the first six months of last year.  The yield on
the Company's average earning assets in the first half of 1998 decreased by 16
basis points to 6.65% from 6.81% in the corresponding period of 1997.  This
decrease was partially offset by a decrease of 3 basis points in the Company's
average cost of funds, from 4.29% for the six months ended June 30, 1997 to 
4.26% for the same period this year.

Provision for Loan Losses
     The provision for loan losses for the first half of 1998 was $90,000 
versus $120,000 for the comparable period in 1997.  This decrease was due to
the lower level of net loan charge-offs which the Bank has experienced in recent
quarters.  For the six months ended June 30, 1998, loan charge-offs net of 
recoveries declined to $19,000 from $122,000 for the same period last year.

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

     Non-interest income for the first six months of 1998 totalled $2,347,000,
up $317,000 or approximately 16% from $2,030,000 reported in the corresponding
period last year.  This increase is due to net gains on securities of $1,428,000
reported for the six months ended June 30, 1998 versus $1,078,000 reported for
the same period last year.  The Company continues to benefit from the stock 
market's strong performance.

Non-Interest Expense
     Non-interest expenses decreased by $744,000, or 10.5% to $6,375,000 in 
the first six months of 1998 from $7,119,000 in the first six months of 1997.

     Salaries and employee benefits, the largest component of non-interest
expense, increased $23,000 or less than 1% from $3,824,000 in the first half
of 1997 to $3,847,000 in the first half of this year.  This increase is due
principally to salary increases and an increase in the Company's employee stock
ownership plan (ESOP) expense.  These were partially offset by a $66,000
reduction in the Company's directors deferred compensation plan expense.

     Occupancy and equipment expenses were $1,027,000 in the first half of 1998
compared to $1,019,000 for the same period in 1997.  As previously noted, 
occupancy and equipment expenses for the first six months of 1998 reflect
the real estate abatements of approximately $54,000 that the Bank received in
the recent quarter, otherwise the expense increase in 1998 would have been 
higher.

     There were no merger and acquisition related expenses incurred in the first
six months of 1998.  In the first six months of last year, the Bank incurred 
merger and acquisition related expenses of $140,000 in connection with its
acquisition of the Glendale Co-operative Bank.

Non-Interest Expense (continued)

     Bank charitable contributions for the first half of 1998 were $7,000 
compared to $656,000 for the same period last year.  During the first half of
1997, the Company established and endowed a tax exempt private foundation --
the "MASSBANK Charitable Foundation" -- for the purpose of making grants in
future years to benefit the Bank's local communities.  MASSBANK contributed
appreciated securities to the Foundation valued at $622,000 which is included
in contributions expense for 1997.

     All other expenses combined, consisting of data processing, professional
services, advertising and marketing, amortization of intangibles, and other
expenses, increased by $14,000 or less than 1.0%, from $1,480,000 for the six
months ended June 30, 1997 to $1,494,000 for the six months ended June 30, 1998.

Income Tax Expense
     The provision for federal and state income taxes increased to $3,377,000 
for the six months ended June 30, 1998 from $2,742,000 for the same period in 
1997.  The Company's combined effective income tax rate for the first half of
1998 is 37.9% compared to 35.8% for the same period a year ago.

     The increase in effective income tax rate is essentially due to a non-
recurring tax benefit of approximately $260,000 that the Bank received last
year as a result of having contributed appreciated securities to the MASSBANK
Charitable Foundation, as previously noted.  Partially offsetting this increase
is a state income tax refund, net of federal tax, of approximately $44,000 that
the Bank received in the first quarter of 1998, representing the final 
settlement of a state income tax issue for prior years.

Financial Condition
     Total assets at June 30, 1998 were $929.7 million, an increase of $4.3
million from $925.4 million at December 31, 1997.

     The Company's securities available for sale and trading securities
portfolios in the first half of 1998 decreased by $36.9 million and $16.3
million, respectively.  Term federal funds sold also decreased from $20.0
million to $10.0 million.  These decreases were offset by increases in short-
term investments of $50.7 million and an increase in the Bank's loan portfolio
of $15.6 million.  Since short-term interest rates have been almost as high as
longer term rates in recent quarters, the Bank has opted to reinvest funds from
payments, sales or maturities of investment securities in (overnight) federal
funds sold.

     MASSBANK's loan portfolio increased to $287.9 million at June 30, 1998
reflecting a net increase in loans of $15.6 million in the six months ended
June 30, 1998.  This improvement was due to an increase in loan originations. 
Loan originations totalled $49.7 million in the six months ended June 30, 1998,
up approximately 75%, or $21.2 million compared to $28.5 million in the six
months ended June 30, 1997.

     Total deposits were $808.7 million at June 30, 1998 essentially unchanged
from $809.9 million at year end 1997.

     Total stockholders' equity rose to $109.4 million at June 30, 1998 from
$103.8 million at December 31, 1997.  Book value increased to $30.44 per share,
from $29.06 per share at year end 1997.  The Company's book value per share has
increased $3.50 or 13.0% since June 30, 1997.

Investments
     Total investments consisting of investment securities, short-term
investments, term federal funds sold and interest-bearing bank deposits 
equalled $623.7 million at June 30, 1998, down $12.0 million from $635.7
million at year end 1997.  These investments are principally in federal funds 
sold, short-term U.S. Treasury notes and government agency fifteen year 
mortgage-backed securities.  The Bank also maintains an equity securities 
portfolio, valued at $20.7 million as of June 30, 1998, that has yielded 
substantial realized and unrealized gains.  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
totalled $298.5 million at June 30, 1998 versus $330.7 million at year end 
1997.

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

_______________________________________________________________________________________

     The Bank's loan portfolio increased $15.6 million during the first six
months of 1998, from $272.3 million at December 31, 1997 to $287.9 million at 
June 30, 1998.  Essentially all of the increase was in the residential 1-4 family 
category.  

     Loan originations increased to $49.7 million in the first six months of 
1998 compared to $28.5 million in the first six months of last year, an 
increase of $21.2 million or 75%.




NON-PERFORMING ASSETS
     The following table shows the composition of the Bank's non-performing assets
at June 30, 1998 and 1997, and December 31, 1997:


                                              At          At               At

____________________________________________________________________________________

     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 increased slightly from December 31, 1997 to 
June 30, 1998 as noted in the table above.  The principal balance of non-
accrual loans was $1.752 million, or approximately 6/10 of 1% of total loans 
and real estate acquired through foreclosure was $71 thousand at June 30, 1998.
Real estate formally acquired in settlement of loans is recorded at the lower 
of the carrying value of the loan or the fair value of the property received, 
less estimated costs to sell the property following foreclosure.  

     The Bank did not have any impaired loans as of June 30, 1998.




ALLOWANCE FOR LOAN LOSSES

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

                                                              Six Months Ended

                                                             1998          1997

_________________________________________________________________________________

Balance at end of period                                 $ 2,405        $ 2,235
_________________________________________________________________________________


     The allowance for loan losses is established through a provision for loan
losses charged to operations based on management's assessment of many factors
including the risk characteristics of the portfolio, underlying collateral, 
current and anticipated economic conditions that may effect the borrowers 
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 
losses, future adjustments to the allowance may be necessary if economic 
conditions differ substantially 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, 1998 the balance of the allowance for loan losses was 
$2,405,000 representing 137.3% 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 decreased by approximately $1.2 million to 
$808.7 million at June 30, 1998 from $809.9 million at December 31, 1997.

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

Recent Accounting Developments

     "Disclosures about Segments of an Enterprise and Related Information"
     In June 1997, the Financial Accounting Standards Board issued SFAS 
No. 131, "Disclosures about Segments of an Enterprise and Related Information".
This Statement establishes standards for reporting information about operating
segments.  An operating segment is defined as a component of an enterprise for
which separate financial information is available and reviewed regularly by
the enterprise's chief operating decision maker in order to make decisions
about resources to be allocated to the segment and also to evaluate the 
segment's performance.  SFAS No. 131 requires a company to disclose certain
balance sheet and income statement information by operating segment, as well
as provide a reconciliation of operating segment information to the company's 
consolidated balances.  This Statement is effective for 1998 annual financial
statements.  Segment information need not be reported in financial statements
for interim periods in the initial year of application.

Recent Accounting Developments (continued)

     In June 1998, the Financial Accounting Standards Board (FASB) issued 
Financial Accounting Standard No. 133, "Accounting for Derivative Instruments 
and Hedging Activities".  This Statement establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, (collectively referred to as derivatives) and for 
hedging activities.  It requires that an entity recognize all derivatives as 
either assets or liabilities in its balance sheet and measure those instruments
at fair market value.  Under this Statement, 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.  This Statement is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999.  This Statement is not expected to have a 
material effect on the Company's consolidated financial statements.


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 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 June 30, 1998 the Bank had $136.3 million or
14.7% of total assets and $126.1 million or 13.6% 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 CAMEL 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 new 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 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 components include supplemental capital components such as
qualifying allowance for loan losses and qualifying subordinated debt.  Tier I
plus the Tier II capital components is referred to as total qualifying capital.

     The capital ratios of the Bank and the Company currently exceed the 
minimum regulatory requirements.  At June 30, 1998, the Bank had a leverage
Tier I capital to total assets ratio of 10.05%, a Tier I capital to risk-
weighted assets ratio of 32.07% and a total capital to risk-weighted assets 
ratio of 32.92%.  The Company, on a consolidated basis, had ratios of leverage
Tier I capital to total assets of 10.63%, Tier I capital to risk-weighted assets
of 33.91% and total capital to risk-weighted assets of 34.75% at June 30, 1998.

Year 2000 Issues
     As we near the 21st century, MASSBANK is taking important steps to tackle
the computer glitch dubbed the Year 2000 Problem, Y2K, or Millennium Bug.  The
problem originated from software designers' attempt to save memory by recording
years in a two-digit format - "98" instead of "1998" for example - but didn't
take into account that the year 2000, or "00" could also be interpreted, by any
system that has time sensitive software, as the year 1900 rather than the year
2000.  This could result in a system failure or in miscalculations.

     In May 1997, the Company organized a Year 2000 project team to address Y2K
critical issues in order to resolve its Year 2000 computer problems.  The team
has completed an assessment of the Company's computer systems to identify the
systems that could be affected by the year 2000 issue and has developed an
implementation plan to address this issue.  It has also begun testing all of 
the Company's computer hardware and software applications and plans to complete
testing of the Company's critical information systems by December 31, 1998.
Testing of the Company's non-critical applications is expected to be completed
by June 30, 1999.

     The Company has incurred and will continue to incur expenses in connection
with the testing and upgrading of its computer systems to prepare for the Year
2000.  Expenditures to date have not been material.  Expenditures for the
remainder of the Year 2000 project are estimated at $50,000 to $250,000, 
depending on the Company's need to upgrade its check processing equipment which
could cost as much as $200,000.  The Company expects to expend approximately
$40,000 in the last half of 1998 and the remainder in the first half of 1999.  
Since the majority of these expenditures will be to replace or upgrade existing
hardware and software, these expenditures will be capitalized and amortized in
accordance with the Company's existing accounting policy.

     The Company uses a third party data center for the majority of its data
processing.  The Year 2000 project team closely monitors the Year 2000 
remediation efforts at the data center to assure that they are meeting their
Year 2000 project objectives.  The data center's remediation progress to date
meets or nearly meets expectations laid out in its Year 2000 project plan.  
Most of the Company's other date sensitive systems operate on software supported
by outside vendors.  The progress made by these vendors to become Y2K compliant
is also being closely monitored.  Letters requesting Year 2000 certification
statements have been sent to all "mission critical" vendors.  Since there is no
guarantee that the Company's data center or outside vendors will become Y2K
compliant, the Company is developing contingency plans.  There is, however, no
guarantee that the systems of other companies, banks, vendors, governmental
agencies, etc. that interface with the Company will be timely remediated.  If 
they are not successful, the Year 2000 problem could have a material affect on
the Company's operations.  Management presently does not believe the Year 2000
issues will pose significant operational problems for the Company. 


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.

Interest Rate Sensitivity and Liquidity
     See discussion and analysis of interest rate sensitivity and liquidity 
provided in the Corporation's Annual Report on Form 10-K for the year ended
December 31, 1997.  There have been no material changes in reported market 
risks faced by the Corporation since the filing of the Corporation's 1997 
Annual Report on Form 10-K.
