                 CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

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

     The accompanying financial statements have been prepared in accordance 
with 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 March 31, 1999
and December 31, 1998, and its operating results for the three months ended 
March 31, 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.  

     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, 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 
quarter ended March 31, 1999 and the year ended December 31, 1998 is as follows:

Results of Operations for the three months ended March 31, 1999

GENERAL
    For the quarter ended March 31, 1999, MASSBANK Corp. reported 
consolidated net income of $2,913,000 or $0.84 in basic earnings per share 
compared to net income of $2,834,000, or $0.80 in basic earnings per share in 
the first quarter of 1998.  Diluted earnings per share increased to $0.82 per 
share from $0.77 per share in the first quarter of last year, representing an
increase of 6.5%.  

    The Company's  favorable earnings results for the recent quarter can be
attributed primarily to higher non-interest income, due to increased securities
gains, and a reduction in non-interest expense.  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.

Net Interest Income
     The Company's net interest income was $6,140,000 for the first quarter
of 1999, a decrease of $432,000 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 first quarter of 1999 was 2.67% down from 2.91% for the
same quarter of the prior year.  Average earning assets for the first quarter of
1999 increased to $925.2 million, up $18.1 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 23 basis points more than did interest-bearing liability
rates, as shown on pages 12 and 13 of this Form 10-Q.

Interest and Dividend Income
     Interest and dividend income on a fully taxable equivalent basis for the
three months ended March 31, 1999, decreased to $14,406,000 from $15,124,000
for the three months ended March 31, 1998.  The average total earning assets
of the Company increased by $18.1 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 12, 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 45 basis points.  The weighted average
yield on earning assets for the first quarter of 1999 was 6.23% compared to 
6.68% 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 March 31, 1999 was 
$8,233,000, down from $8,521,000 for the same quarter last year.  The Company's
average deposits, as shown in the table on page 13, increased $14.1 million or 
1.7% to $821.5 million in the first quarter of 1999, from $807.4 million in the
first 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 March 31, 1999 was 4.06%, down from 4.28% 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 first quarter of 1999 was $50,000
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 netted to zero compared to net 
charge-offs on loans of $2,000 for same quarter last year.

     The reserve coverage as a percentage of the Bank's non-performing assets
increased in the recent quarter.  At March 31, 1999, MASSBANK's allowance
for loan losses totalled $2,500,000 representing 341.5% of non-performing
assets compared to $2,377,000 representing 152.3% of non-performing assets 
at the end of the first quarter in 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 $1,741,000 for the quarter ended March 31,
1999, from $1,246,000 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 $1,378,000 in the first quarter of this
year compared to $812,000 in the first quarter of the prior year.  The Bank's 
equity securities portfolio continues to provide the Bank with significant 
returns.  Realized gains on the sale of equity securities totaled $1,424,000 
for the three months ended March 31, 1999.  The Bank also recorded a mark-to-
market gain on its trading account of $13,000 during this same period.  These 
gains, however, were partially offset by net losses realized on the sale of 
debt securities of $59,000.

     The Bank's deposit account service fees and other non-interest income 
totaled $178,000 and $185,000, respectively, in the first quarter of 1999 
compared to $211,000 and $223,000, respectively, in the first quarter of 1998. 

Non-Interest Expense
     Non-interest expense decreased by $88,000, or 2.7% to $3,168,000 in the
first quarter of 1999 from $3,256,000 in the first quarter of 1998.

     Salaries and employee benefits, the largest component of non-interest
expense, decreased by $104,000 or 5.3% from $1,973,000 in the first quarter of
1998 to $1,869,000 in the recent quarter.  This reduction is due primarily to a
decrease of $65,000 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 $29,000 in loan origination 
related salary expenses (which are amortized over the life of the loan) being
deferred due to increased residential lending activity.

     Occupancy and equipment expense was $547,000 in the first quarter of 1999,
essentially unchanged from $555,000 in the first quarter of last year.

     All other expenses combined, consisting of data processing, professional
services, advertising and marketing, amortization of intangibles and other 
expenses, increased by $24,000 from $728,000 for the three months ended
March 31, 1998 to $752,000 for the three months ended March 31, 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 increased to $1,750,000 
for the three months ended March 31, 1999 from $1,683,000 for the same period 
in 1998.  This increase is due to higher income before income taxes and a 
modest increase in the Company's effective income tax rate.  The Company's 
combined effective income tax rate for the first quarter of 1999 is 37.5% 
compared to 37.3% for the same quarter a year ago.

Financial Condition
     Total assets at March 31, 1999 were $941.9 million, a decrease of $4.7
million from $946.6 million at December 31, 1998.

     The decrease in total assets was driven by an $11.6 million decrease in the
investment portfolio, partially offset by $7.1 million growth in net loans.  
Other assets decreased by $0.2 million in the first quarter 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 $612.5 million 
at March 31, 1999.  The decrease is mainly attributable to the Bank's trading
securities portfolio which declined approximately $14.9 during the recent 
quarter.  This reduction was partially offset by an increase in the Bank's
investment in debt and equity securities available for sale which grew by 
$7.5 million this past quarter.

     MASSBANK's net loan portfolio increased to $309.7 million at March 31, 1999
reflecting a net increase in loans of $7.1 million in the first three months of
1999.  This improvement results from an increase in loan originations.  Loan
originations totalled $24.6 million in the three months ended March 31, 1999, 
up approximately 24%, or $4.8 million from $19.8 million in the first three 
months of 1998.

     Total deposits were $822.0 million at March 31, 1999 reflecting a modest
reduction from $824.0 million at year end 1998.

     Total stockholders' equity declined to $108.3 million at March 31, 1999 
from $110.5 million at December 31, 1998.  The decrease results primarily from 
the cost of the 54,485 shares of (MASSBANK Corp.) treasury stock that the 
Company repurchased during the recent quarter for a total amount of $2.1 million
and a reduction in net unrealized gains, net of tax effect, on the Company's
available for sale securities in the amount of $2.2 million.  These decreases 
were partially offset by an increase of $2.0 million in the Company's retained
earnings in the recent quarter.  As a result, the Company's book value per 
share decreased to $31.42 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 $612.5 million at March 31, 1999, down $11.6 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 $23.3 million as of 
March 31, 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
totalled $261.0 million at March 31, 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 $7.2 million during the first three
months of 1999, from $305.0 million at December 31, 1998 to $312.2 million at 
March 31, 1999.  Essentially all of the increase was in the residential 1-4
family category.  

     Loan originations increased to $24.6 million in the first quarter of 1999 
compared to $19.8 million in the first quarter of last year, an increase of 
$4.8 million or 24%.




NON-PERFORMING ASSETS
     The following table shows the composition of the Bank's non-performing 
assets at March 31, 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 March 31, 1999 
as noted in the table above.  The principal balance of non-accrual loans 
was down to $732,000, or approximately one-quarter of 1% of total loans at 
March 31, 1999.

     The Bank did not have any real estate acquired through foreclosure or 
impaired loans as of March 31, 1999.





ALLOWANCE FOR LOAN LOSSES

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

                                                            Three Months Ended
                                                                 March 31,

_________________________________________________________________________________

Balance at end of period                                 $ 2,500        $ 2,377
_________________________________________________________________________________


     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 March 31, 1999 the balance of the allowance for loan losses was 
$2,500,000 representing 341.5% 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 $2.0 million to $822.0 million at
March 31, 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:




                                                March 31,        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.  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 March 31, 1999 the Bank had $144.2 million or 
15.3% of total assets and $156.1 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 ("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 March 31, 1999, the Bank had a leverage
Tier I capital to total assets ratio of 10.33%, a Tier I capital to risk-
weighted assets ratio of 31.28% and a total capital to risk-weighted assets 
ratio of 33.35%.  The Company, on a consolidated basis, had ratios of leverage
Tier I capital to total assets of 10.46%, Tier I capital to risk-weighted assets
of 31.68% and total capital to risk-weighted assets of 33.75% at March 31, 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 $126 thousand.  First
quarter 1999 expenditures totalled $73,000.  Approximately $21 thousand of the 
first quarter 1999 expenditures were expensed as incurred, while the cost of 
new hardware and software of approximately $52 thousand was capitalized and 
will be amortized over the software and hardware's useful life.  The capitalized
expenditures represent the partial 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 $200 thousand.  This includes the remaining cost of approximately $110
thousand to upgrade the Bank's check processing equipment.  Since the majority 
of these expenditures will be to replace or upgrade existing hardware and 
software, the majority of these expenditures will be capitalized and amortized
in accordance with the Company's standard accounting practices.

     The Company relies on a third party service bureau for its primary business
processes (e.g., loans and deposits applications).  It continues to work 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.  The Company's testing 
with the service bureau that began April 1998 is expected to be substantially
completed by the end of the second quarter of 1999.  However, the Company may
continue testing into the third quarter of 1999.

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, with the exception of its trust and 
items processing department systems.  These systems are being replaced with 
hardware and software that is Year 2000 ready.  The systems were delivered in
March 1999 and will be installed and operational in the second quarter of 1999. 
The Company expects testing of these systems to be substantially completed by 
the end of the second quarter of 1999.

     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 is expected to be substantially completed by June 30, 1999.
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 continues to 
test 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 drafted contingency and business resumption plans for its primary
lines of business.  These plans are being enhanced to address potential Year 
2000 scenarios.  This process will be completed by the end of the second 
quarter of 1999.

     The expenditures of the project and the dates on which the Bank plans to
complete Year 2000 testing and contingency and business resumption plans, 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.  In addition, the Company's
efforts to address the Year 2000 issue are being monitored by its federal 
banking regulators.  Failure to be Year 2000 compliant on a timely basis could
subject the Company to formal supervisory or enforcement actions.



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.
