presentation of the financial condition of the Company as of June 30, 1999
and December 31, 1998, and its operating results for the three and six months
ended June 30, 1999 and 1998.  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.

10-K for the year ended December 31, 1998.

(5)  Reporting Comprehensive Income
     The Company has adopted Statement of Financial Accounting Standards
No. 130, "Reporting Comprehensive Income."  This Statement establishes standards
for the reporting and displaying of 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", is used in the Statement to describe
the total of all components of comprehensive income including net income.

     The Company's other comprehensive income and related tax effect for the
six months ended June 30, 1999 and the year ended December 31, 1998 is as
follows:

Cautionary Statement.
    Certain statements contained in this report or incorporated herein by
reference are "forward-looking statements."  We may also make written or oral
forward-looking statements in other documents we file with the SEC, in our
annual reports to stockholders, in press releases and other written materials,
and in oral statements made by our officers, directors or employees.  You can
identify forward-looking statements by the use of the words "believe," "expect,"
"anticipate," "intend," "estimate," "assume" and other similar expressions which
predict or indicate future events and trends and which do not relate to
historical matters.  In addition, information concerning the costs, timing and
effectiveness of Year 2000 compliance, are forward-looking statements.  You
should not rely on forward-looking statements, because they involve known and
unknown risks, uncertainties and other factors, some of which are beyond the
control of the Company.  These risks, uncertainties and other factors may cause
the actual results, performance or achievements of the Company to be materially
different from the anticipated future results, performance or achievements
expressed or implied by the forward-looking statements.

    Some of the factors that might cause these differences include the
following: fluctuations in interest rates, price volatility in the stock and
bond markets, inflation, government regulations and economic conditions and
competition in the geographic and business areas in which the Company conducts
its operations; and the Company and its customers and suppliers may experience
unanticipated delays or expenses in achieving Year 2000 compliance.  You should
carefully review all of these factors, and you should be aware that there may
be other factors that could cause these differences.  These forward-looking
statements were based on information, plans and estimates at the date of this
report, and we do not promise to update any forward-looking statements to
reflect changes in underlying assumptions or factors, new information, future
events or other changes.


Results of Operations for the three months ended June 30, 1999

GENERAL
    For the quarter ended June 30, 1999, MASSBANK Corp. reported consolidated
net income of $2,866,000 or $0.85 in basic earnings per share compared to net
income of $2,706,000, or $0.76 in basic earnings per share in the second quarter
of 1998.  Diluted earnings per share increased to $0.82 per share from $0.73 per
share in the second quarter of last year, representing an increase of 12.3%.

    The Company's  favorable earnings results for the recent quarter can be
attributed primarily to an increase of $515,000 in securities gains, reflecting
the favorable performance of the Bank's equity securities portfolio, and a
decrease in income tax expense due to a lower effective income tax rate.  These
improvements were partially offset by a decrease in net interest income
resulting from a decline in net interest margin, partially offset by an
increase in average earning assets.  The second quarter earnings results also
reflect modest reductions in deposit account service fees and other non-
interest income, and a modest increase in the Bank's provision for loan losses.

Net Interest Income
     The Company's net interest income was $6,130,000 for the second quarter
of 1999, a decrease of $333,000 from the same quarter a year ago.  This decrease
is the result of a lower net interest margin, partially offset by the positive
effect of growth in the Company's average earning assets.  The Company's net
interest margin for the second quarter of 1999 was 2.66% down from 2.86% for the
same quarter of the prior year.  Average earning assets for the second quarter
of 1999 increased to $926.6 million, up $18.0 million from the corresponding
quarter in 1998.  MASSBANK's net interest margin over the last twelve months has
been negatively impacted by reductions in the Federal Funds rate, an overall
decline in market interest rates, and the slope of the yield curve.  As market
interest rates declined and as the yield curve flattened in 1998, MASSBANK's
interest-earning asset yields decreased faster than did its interest-bearing
liability rates.  The interest rate spread contracted because interest-earning
asset yields decreased 15 basis points more than did interest-bearing liability
rates, as shown on pages 13 and 14 of this Form 10-Q.

Interest and Dividend Income
     Interest and dividend income on a fully taxable equivalent basis for the
three months ended June 30, 1999, decreased to $14,372,000 from $15,056,000
for the three months ended June 30, 1998.  The average total earning assets
of the Company increased by $18.0 million, as noted above.  The increase in
interest income resulting from the growth in earning assets in the recent
quarter, however, was more than offset by a decline in yield on earning assets.
As reflected in the table on page 13, yield declines in each of the Bank's
categories of earning assets resulted in an overall decline in yield on the
Company's total average earning assets of 42 basis points.  The weighted average
yield on earning assets for the second quarter of 1999 was 6.20% compared to
6.62% in the same quarter of the prior year.

Interest Expense
     Total interest expense for the three months ended June 30, 1999 was
$8,215,000, down from $8,562,000 for the same quarter last year.  The Company's
average deposits, as shown in the table on page 14, increased $20.5 million or
2.5% to $828.6 million in the second quarter of 1999, from $808.1 million in the
second quarter of 1998.  The decrease in interest expense resulted from a
decrease in average cost of funds partially offset by the additional interest
expense resulting from the higher deposit volume.  The Company's average cost of
funds for the three months ended June 30, 1999 was 3.98%, down from 4.25% for
the comparable period in 1998.

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.


Provision for Loan Losses (continued)
    The provision for loan losses for the second quarter of 1999 was $60,000
versus $45,000 for the comparable period in 1998.  This increase is essentially
due to the growth in the Bank's loan portfolio.  In the recent quarter, the
Bank's loan charge-offs net of recoveries were $2,000, down from $17,000 for
same quarter last year.

     The reserve coverage as a percentage of the Bank's non-performing assets
increased in the recent quarter.  At June 30, 1999, MASSBANK's allowance for
loan losses totaled $2,558,000 representing 267% of non-accrual loans compared
to $2,405,000 representing 137% of non-accrual loans at the end of the second
quarter 1998.

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

     Non-interest income increased to $1,578,000 for the quarter ended June 30,
1999, from $1,101,000 for the comparable quarter of the prior year.  This
improvement is due to an increase in securities gains in 1999.

     Net gains on securities totaled $1,131,000 in the second quarter of this
year compared to $616,000 in the second quarter of the prior year.  The Bank's
equity securities portfolio continues to provide the Bank with favorable
returns.  Realized gains on the sale of equity securities totaled $1,343,000
for the three months ended June 30, 1999.  These gains, however, were partially
offset by net losses realized on the sale of debt securities of $189,000.  The
Bank also recorded a mark-to-market loss of $23,000 on its trading account
during this same period.

     The Bank's deposit account service fees and other non-interest income
totaled $178,000 and $269,000, respectively, in the second quarter of 1999
compared to $210,000 and $275,000, respectively, in the second quarter of 1998.

Non-Interest Expense
     Non-interest expense was $3,122,000 for the second quarter 1999,
essentially unchanged from the second quarter 1998 total of $3,119,000.

     Salaries and employee benefits, the largest component of non-interest
expense, increased by a modest $19,000 or 1.0% in the second quarter of 1999 to
$1,893,000.  The increase is due essentially to an increase in employee benefits
expenses (higher profit sharing and incentive compensation bonus plan and
executive supplemental retirement plan expenses, partially offset by a decrease
in the Bank's employee stock ownership Plan expense).

     Occupancy and equipment expense increased by $40,000 to $512,000 in the
recent quarter from $472,000 in the second quarter of 1998.  This increase is
due primarily to real estate tax abatements for 1998 and prior years that the
Bank received in 1998.

     All other expenses combined, consisting of data processing, professional
services, advertising and marketing, amortization of intangibles and other
expenses, decreased by $56,000 from $773,000 for the three months ended
June 30, 1998 to $717,000 for the three months ended June 30, 1999.  This was
due partly to lower expenses on foreclosed real estate in 1999.

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 decreased to $1,660,000
for the three months ended June 30, 1999 from $1,694,000 for the same period
in 1998.  This decrease is due to a reduction in the Company's effective income
tax rate, partly offset by an increase in income taxes due to the higher income
before income taxes in the recent quarter.  The Company's combined effective
income tax rate for the second quarter of 1999 is 36.7% compared to 38.5% for
the same quarter a year ago.


Results of Operations for the six months ended June 30, 1999
     For the six months ended June 30, 1999, the Company reported consolidated
net income of $5,779,000 or $1.69 in basic earnings per share ($1.64 per share
on a diluted basis) compared to net income of $5,540,000 or $1.56 in basic
earnings per share ($1.50 per share on a diluted basis) earned in the first half
of 1998.

     The Company's positive financial performance in the first six months of
1999 reflects an increase in securities gains of $1,081,000 due to the
favorable performance of the Bank's equity securities portfolio, partially
offset by a decrease in net interest income of $765,000.  The lower net interest
income results from a decline in net interest margin, partially offset by modest
growth in the Company's average earning assets.  Average earning assets for the
first half of 1999 increased to $925.9 million, up $18.1 million from the
corresponding period in 1998.

     The Company's earnings results for the six months ended June 30, 1999 were
also impacted by a modest increase in the provision for loan losses and income
tax expense, and modest reductions in deposit account service fees, other non-
interest income, and total non-interest expense.

Net Interest Income
     Net interest income was $12,270,000 for the six months ended June 30,
1999, reflecting a decrease of $765,000 from the same period a year ago.  This
decrease is the result of a lower net interest margin, partially offset by
modest growth in the Company's average earning assets.  The Company's net
interest margin for the first half of 1999 was 2.66%, down from 2.89% for the
comparable period in 1998.  Average earning assets for the six months ended
June 30, 1999 increased $18.1 million or 2.0% to $925.9 million from $907.8
million for the corresponding period in 1998.

     The Company's interest rate spread decreased to 2.20% for the first six
months of 1999, from 2.39% in the first six months of last year.  The yield on
the Company's average earning assets in the first half of 1999 decreased by 43
basis points to 6.22% from 6.65% in the corresponding period of 1998.  This
decrease was partially offset by a decrease of 24 basis points in the Company's
average cost of funds, from 4.26% for the six months ended June 30, 1998 to
4.02% for the same period this year.

Provision for Loan Losses
     The provision for loan losses for the first half of 1999 was $110,000
versus $90,000 for the comparable period in 1998.  This increase is essentially
due to the growth in the Bank's loan portfolio during the last twelve months.
Loan charge-offs net of recoveries for the six months ended June 30, 1999
declined to $2,000 from $19,000 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 1999 totaled $3,319,000,
up $972,000 or approximately 41% from $2,347,000 reported in the corresponding
period last year.  This increase is due to net gains on securities of $2,509,000
reported for the six months ended June 30, 1999 versus $1,428,000 reported for
the same period last year.  The Company continues to benefit from the strong
performance of its stock portfolio.  Deposit account service fees and other non-
interest income combined decreased $109,000 to $810,000 in the first half of
1999 from $919,000 in the first half of 1998.

Non-Interest Expense
     Non-interest expense decreased by $85,000, or 1.3% to $6,290,000 in
the first six months of 1999 from $6,375,000 in the first six months of 1998.
This was due primarily to a decrease in salaries and employee benefits
expenses.

     Salaries and employee benefits, the largest component of non-interest
expense, decreased by $85,000 or just over 2% from $3,847,000 in the first half
of 1998 to $3,762,000 in the first half of this year.  This reduction is due
primarily to a decrease of $90,000 in compensation and benefits expenses which
are tied to the Company's stock performance.  Also contributing to the reduction
in salaries and employee benefits expenses was an increase of $46,000 in loan
origination related salary expenses (which are amortized over the life of the
loan) being deferred.  These reductions were partially offset by an increase of
$50,000 in the Company's profit sharing and incentive compensation bonus plan
expense for the first six months of 1999.

Non-Interest Expense (continued)

     All other expenses combined, consisting of occupancy and equipment,
data processing, professional services, advertising and marketing, amortization
of intangibles and other expenses totaled $2,528,000 for the first half of
1999, unchanged from the first half of 1998.

Income Tax Expense
     The provision for federal and state income taxes increased to $3,410,000
for the six months ended June 30, 1999 from $3,377,000 for the same period in
1998.  This increase is due primarily to an increase in income before taxes
in the first half of 1999, partly offset by a reduction in the Company's
effective income tax rate.  The Company's combined effective income tax rate
for the first half of 1999 is 37.1% compared to 37.9% for the same period a
year ago.

     The Company's income tax expense for the first six months of 1998 includes
a state income tax refund, net of federal tax, of approximately $44,000 which
the Company received in 1998, representing the financial settlement of a state
income tax issue for prior years.

Financial Condition
     Total assets at June 30, 1999 were $946.0 million, a decrease of $0.6
million from $946.6 million at December 31, 1998.

     While total assets as of June 30, 1999 are essentially unchanged from
year-end 1998 the Company's balance sheet does reflect some changes in asset
mix.  The Company's investment portfolio decreased by $27.1 million during the
six months ended June 30, 1999.  This decrease, however, is offset by an
increase of $26.7 million in net loans.  Other assets decreased by $0.2 million
in the first half of 1999.

     Total investments consisting of investment securities and other short-term
investments, including term federal funds sold and interest-bearing bank
deposits, decreased from $624.1 million at December 31, 1998 to $597.0 million
at June 30, 1999.  The decrease is mainly attributable to the Bank's trading
securities portfolio, term federal funds sold and short-term investments which
declined $24.8 million, $25.0 million and $6.9 million respectively, during the
first half of 1999.  These reductions were partially offset by an increase in
the Bank's investment in debt and equity securities available for sale which
grew by $28.2 million during this same period.

     MASSBANK's net loan portfolio increased to $329.2 million at June 30, 1999
reflecting a net increase in loans of $26.7 million in the first six months of
1999.  This improvement results from an increase in loan originations.  Loan
originations totaled $61.0 million in the six months ended June 30, 1999, up
approximately 23%, or $11.3 million from $49.7 million in the first six
months of 1998.

     Total deposits were $829.3 million at June 30, 1999 reflecting an increase
of $5.3 million from $824.0 million at year-end 1998.

     Total stockholders' equity declined to $104.4 million at June 30, 1999
from $110.5 million at December 31, 1998.  The decrease results primarily from
a reduction in net unrealized gains, net of tax effect, on the Company's
available for sale securities in the amount of $6.4 million, and the cost of
the 103,485 shares of (MASSBANK Corp.) treasury stock that the Company
repurchased during the first half of 1999 for a total amount of $3.9 million.
These decreases were partially offset by an increase of $3.9 million in the
Company's retained earnings in the six months ended June 30, 1999.  As a result,
the Company's book value per share decreased to $30.67 per share, from $31.58
per share at year-end 1998.


Investments
     As previously noted, total investments consisting of investment securities,
short-term investments, term federal funds sold and interest-bearing bank
deposits equalled $597.0 million at June 30, 1999, down $27.1 million from
$624.1 million at year end 1998.  These investments are principally in federal
funds sold, short-term U.S. Treasury and government agency obligations and
government agency fifteen year mortgage-backed securities.  The Bank also
maintains an equity securities portfolio, valued at $21.7 million as of
June 30, 1999, 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
totaled $277.6 million at June 30, 1999 versus $272.6 million at year end 1998.

     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 $26.8 million during the first six
months of 1999, from $305.0 million at December 31, 1998 to $331.8 million at
June 30, 1999.  The increase was primarily in the commercial loan and residential
1-4 family mortgage loan categories.

     Loan originations increased to $61.0 million in the first six months of 1999
compared to $49.7 million in the first six months of last year, an increase of
$11.3 million or 23%.






NON-PERFORMING ASSETS
     The following table shows the composition of the Bank's non-performing
assets at June 30, 1999 and 1998, and December 31, 1998:

____________________________________________________________________________________

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

     Non-performing assets decreased from December 31, 1998 to June 30, 1999
as noted in the table above.  The principal balance of non-accrual loans
was down to $959,000, or approximately one-quarter of 1% of total loans at
June 30, 1999.

     The Bank did not have any real estate acquired through foreclosure or
impaired loans as of June 30, 1999.




ALLOWANCE FOR LOAN LOSSES

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

                                                             Six Months Ended

________________________________________________________________________________


     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, 1999 the balance of the allowance for loan losses was
$2,558,000 representing 266.7% of non-accrual loans.  Management believes that
the allowance for loan losses is adequate to cover the risks inherent in the
portfolio under current conditions.


DEPOSITS

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

     The Bank's total deposits increased by $5.3 million to $829.3 million at
June 30, 1999 from $824.0 million at December 31, 1998.

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

                                                June 30,        December 31,

Recent Accounting Developments

     "Accounting for Derivative Instruments and Hedging Activities"
     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.  In June 1999, FASB issued Statement No. 137, "Accounting for Derivative
Instruments and Hedging Activities - Deferral of the Effective Date of Statement
No. 133" which defers the effective date of Statement No. 133.  Statement No.
133 is now effective for all fiscal quarters of fiscal years beginning after
June 15, 2000.  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, 1999 the Bank had $116.2 million or
12.3% of total assets and $151.9 million or 16.1% of total assets invested,
respectively, in overnight federal funds sold and United States obligations.

     The Bank is a Federal Deposit Insurance Corporation ("FDIC") insured
institution subject to the FDIC regulatory capital requirements.  The FDIC
regulations require all FDIC insured institutions to maintain minimum levels
of Tier 1 capital.  Highly rated banks (i.e., those with a composite rating
of 1 under the CAMELS rating system) are required to maintain a minimum leverage
ratio of Tier 1 capital to total assets of at least 3.00%.  An additional 100
to 200 basis points are required for all but these most highly rated
institutions.  The Bank is also required to maintain a minimum level of
risk-based capital.  Under the 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 and up
to 45 percent of the pre-tax net unrealized holding gains on certain available
for sale equity securities.  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, 1999, the Bank had a leverage
Tier I capital to total assets ratio of 10.31%, a Tier I capital to risk-
weighted assets ratio of 30.14% and a total capital to risk-weighted assets
ratio of 32.15%.  The Company, on a consolidated basis, had ratios of leverage
Tier I capital to total assets of 10.37%, Tier I capital to risk-weighted assets
of 30.30% and total capital to risk-weighted assets of 32.31% at June 30, 1999.

Year 2000 Issue
     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 the
Y2K critical issues in order to resolve its Year 2000 computer problems.  The
project team provides direct oversight of the Year 2000 initiative.  The
Company's Board of Directors receives project updates on a quarterly basis and
the Bank's Board of Directors receives a monthly project update.

     The project team has completed its assessment of the Company's technology
and non-information technology systems, such as vault doors, elevators, and
security systems, to identify the systems that could be affected by the Year
2000 issue and has developed a plan to address this issue.  The project plan,
which incorporates the Federal Financial Institutions Examination Council
("FFIEC") recommended guidelines, encompasses a service bureau for systems that
are outsourced, in-house systems, vendors, customers and suppliers (including
correspondent banks).  In addition to addressing the Company's technology
issues, the project plan includes a customer awareness program designed to keep
the Bank's customers informed about the Year 2000 issue and the Company's state
of readiness.

     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.  Year 2000 project expenditures to-date approximate $236,000.
Expenditures for the first half of 1999 totaled $182,000.  Approximately $27,000
of the current year's expenditures were expensed as incurred, while the cost of
new hardware and software of approximately $155,000 was capitalized and will be
amortized over the software and hardware's useful life in accordance with the
Company's standard accounting practices.  The capitalized expenditures represent
the payment on new check processing equipment and the replacement of some
personal computers and VCRs that were not Year 2000 ready.  Expenses for the
remainder of the Year 2000 project are not expected to exceed $100,000.

     The Company relies on a third party service bureau for its primary business
processes (e.g., loans and deposits applications).  It has worked closely with
the service bureau to monitor the progress of their Year 2000 efforts.  The
service bureau's Y2K remediation efforts are also being monitored by the federal
banking regulators.  The service bureau has substantially completed the
remediation and testing of all its applications and the Company has successfully
completed testing with the service bureau.

Year 2000 (continued)

     The Company has made significant progress in testing, upgrading, and/or
replacing its information systems to assure Y2K compliance.  The testing of all
of the Company's computer hardware and mission critical internal information
systems has been substantially completed.

     Most of the Company's other date sensitive systems operate on software
supported by outside vendors.  The Company continues to monitor the progress of
their Year 2000 efforts and is seeking to receive written verification from
these vendors as to their Year 2000 readiness.

     Testing of the Company's non-mission critical internal information systems
and interfaces has also been substantially completed.  Examination of the
Company's non-information technology systems indicated that no significant
replacements are required for Year 2000 readiness.

     While the Company continues to receive written verification from its
service bureau and vendors as to their Year 2000 compliance, and has tested some
of their systems, there is no guarantee that these systems will not fail in
the Year 2000.  Also, there can be no assurance that the systems of other
companies, banks, government agencies, etc. that interface with the Company
will be timely remediated.  If they are not successful, the Year 2000 problem
could have a material effect on the Company's operations.  The Company,
therefore, has developed a business resumption contingency plan for its primary
lines of business.  The Plan, which addresses various potential Year 2000
scenarios, was completed in the second quarter 1999 and continues to be
enhanced.

     The expenditures of the project are based on management's best estimates,
which were derived utilizing numerous assumptions of future events including the
continued availability of certain resources, third party modification plans and
other factors.

     Management presently does not believe that the Year 2000 issue will result
in significant operational problems for the Company.  Management believes that
the Company is now ready for the year 2000.

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.
