                 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 September 30, 1998
and December 31, 1997, and its operating results for the three and nine months
ended September 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:

have original maturities of 90 days or less.

(4)  Commitments
     At September 30, 1998, the Company had outstanding commitments to originate
mortgage loans and to advance funds for construction loans amounting to
$6,691,000 and commitments under existing home equity lines of credit and other
loans of approximately $25,859,000 which are not reflected on the consolidated
balance sheet.  In addition, as of September 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.

(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
nine months ended September 30, 1998 and the year ended December 31, 1997 is as
follows:

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


GENERAL
    For the quarter ended September 30, 1998, MASSBANK Corp. reported 
consolidated net income of $2,695,000 or $0.76 in basic earnings per share 
compared to net income of $2,589,000, or $0.74 in basic earnings per share in 
the third quarter of 1997.  Diluted earnings per share increased to $0.73 per 
share from $0.70 per share in the third quarter of last year.  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  favorable earnings results for the recent quarter can be
attributed to a decrease in non-interest expense, income tax expense, and 
provision for loan losses.  These improvements were partially offset by a 
reduction in non-interest income and a decrease in net interest income resulting
from a decline in net interest margin.  The Company's net interest margin for 
the third quarter of 1998 was 2.77% compared to 2.88% for the same quarter a 
year earlier.  Non-interest expense for the third quarter of 1998, when compared
to the same quarter of 1997, shows a decrease of $320,000.

(4)  Includes the effects of SFAS No. 115.


Net Interest Income
     Net interest income was $6,292,000 for the third quarter of 1998 
compared to $6,523,000 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 $3.2 million to $913.9 million
in the third quarter of 1998, up from $910.7 million in the third quarter of
the prior year.  The Company's net interest margin was 2.77% in the recent 
quarter, down from 2.88% 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 September 30, 1998, decreased to $14,995,000 from $15,460,000
for the three months ended September 30, 1997.  The average total earning assets
of the Company increased by $3.2 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 23 basis points.  The weighted 
average yield on earning assets for the third quarter of 1998 was 6.56% compared
to 6.79% 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 September 30, 1998 was 
$8,703,000, down from $8,937,000 for the same quarter last year.  The 
Company's average deposits, as shown in the table on page 14, decreased $9.7
million or 1.2% to $812.1 million in the third quarter of 1998, from $821.8
million in the third quarter of 1997.  The decrease in interest expense resulted
from a decrease in average cost of funds and a decrease in total deposits.  The
Company's average cost of funds for the three months ended September 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
best 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 third quarter of 1998 was $15,000
versus $45,000 for the comparable period in 1997.  This decrease was 
essentially due to lower net loan charge-offs.  In the recent quarter the
Bank recorded net recoveries on loans of $5,000 compared to net charge-offs 
on loans of $131,000 for same quarter last year.

Provision for Loan Losses (continued)
     The reserve coverage as a percentage of the Bank's non-performing assets
increased in the recent quarter.  At September 30, 1998, MASSBANK's allowance
for loan losses totalled $2,425,000 representing 166.2% of non-performing
assets compared to $2,254,000 representing 155.1% of non-performing assets 
at the end of the third 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 third quarter of 1998 was $796,000, down from
$886,000 for the comparable period in 1997.  This decrease is due to lower 
deposit account service fees and a decrease in other income, partially offset 
by slightly higher securities gains.  The Bank's other non-interest income 
reflects a decrease in income earned on the Bank's deferred compensation plan
assets, the result of the stock market performance in the recent quarter.  The 
Plan incurred a loss of $30,000 in the recent quarter, compared to income of 
$16,000 for the same quarter last year.  Since the Bank reflects a corresponding
deferred compensation plan liability on its balance sheet, it has recorded an
offsetting reduction in deferred compensation expense for the third quarter 1998
that is included in salaries and employee benefits.

Non-Interest Expense
     Non-interest expenses decreased by $320,000, or 10.0% to $2,871,000 in the
third quarter of 1998 from $3,191,000 in the third quarter of 1997.

     Salaries and employee benefits, the largest component of non-interest
expense, decreased by $385,000 or 19.4% from $1,983,000 in the third quarter of
1997 to $1,598,000 in the recent quarter.  This reduction is due largely to a
decrease of $247,000 in the Company's directors deferred compensation plan 
expense and a decrease of $98,000 in the expense amount provided for payments
to employees under the Bank's profit sharing and incentive compensation bonus 
plans.  The expense related to the directors deferred compensation 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 third quarter 1997, 
from $35.8125 per share at June 30, 1997 to $47.50 per share at September 30, 
1997, significantly increased the expense for the plan.  Conversely, the price
of the Company's common stock in the recent quarter having declined from $49.00
per share at June 30, 1998 to $38.75 per share at September 30, 1998, decreased
the expense for the plan.

     Occupancy and equipment expense was $522,000 in the third quarter of 1998,
essentially unchanged from $527,000 in the third quarter of last year.

     There were no merger and acquisition related expenses incurred in the 
third quarter of 1998.  In the third quarter of last year, the Bank incurred
merger and acquisition related expenses of $16,000 in connection with its
acquisition of the Glendale Co-operative Bank.

     Data processing expenses increased from $71,000 for the quarter ended 
September 30, 1997 to $132,000 for the quarter ended September 30, 1998.  In 
the third quarter of last year, the Bank transferred its data processing to a
different service bureau.  As part of the initial contract that the Bank 
negotiated with the new service bureau it received $150,000 in total credits 
that were to be applied against data processing expenses in 1997.  One half or
$75,000 was applied in the third quarter of 1997 and the remaining balance was
applied in the fourth quarter of last year, significantly reducing data
processing expenses for the second half of 1997.


Non-Interest Expense (continued)
     All other expenses combined, consisting of professional services, 
advertising and marketing, amortization of intangibles, contributions and 
other expenses, increased by $25,000 from $594,000 for the three months ended
September 30, 1997 to $619,000 for the three months ended September 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 decreased to $1,507,000 
for the three months ended September 30, 1998 from $1,584,000 for the same 
period in 1997.  This decrease is due to a reduction in the Company's 
effective income tax rate.  The Company's combined effective income tax rate 
for the third quarter of 1998 is 35.9% compared to 38.0% for the same quarter 
a year ago.

Results of Operations for the nine months ended September 30, 1998

General
     For the nine months ended September 30, 1998, the Company reported 
consolidated net income of $8,235,000 or $2.32 in basic earnings per share 
($2.23 per share on a diluted basis) compared to net income of $7,511,000 or 
$2.13 in basic earnings per share ($2.05 per share on a diluted basis) earned 
in the first nine months of 1997.  This represents an increase in net income of
9.6%.

     The Company's positive financial performance in the first nine months of
1998 reflects a decrease in non-interest expense of $1,064,000 or 10.3%.  Non-
interest expenses for the nine months ended September 30, 1998 were $9,246,000, 
down from $10,310,000 for the comparable period in 1997.  In addition, non-
interest income for the nine months ended September 30, 1998 increased by 
$227,000 due to increased securities gains.

     The Company's earnings results for the nine months ended September 30, 1998
were also impacted by the following factors:

    a)  Net interest income decreased by $69,000 to $19,327,000 for the 
        first nine months of 1998, from $19,396,000 for the same period 
        in 1997.

    b)  The Bank's provision for loan losses for the nine months ended 
        September 30, 1998 decreased by 36% to $105,000 from $165,000 for the
        comparable period in 1997.

    c)  Income tax expense increased in the first nine months 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.

Net Interest Income
     Net interest income totalled $19,327,000 for the first nine months of 
1998 compared to $19,396,000 for the same period in 1997.  The decrease of
$69,000 was due principally to a decrease in net interest margin.  The impact 
of the lower net interest margin in 1998 was partially offset by an increase 
in the Company's average earning assets from $888.5 million in the first nine 
months of 1997 to $909.9 million in the first nine months of 1998.  The 
Company's net interest margin for the nine months ended September 30, 1998 
was 2.85%, 8 basis points lower than the 2.93% for the comparable period of the
prior year.

     The Company's interest rate spread decreased to 2.36% for the first nine
months of 1998, from 2.50% in the first nine months of last year.  The yield on
the Company's average earning assets in the first half of 1998 decreased by 18
basis points to 6.62% from 6.80% in the corresponding period of 1997.  This
decrease was partially offset by a decrease of 4 basis points in the Company's
average cost of funds, from 4.30% for the nine months ended September 30, 1997 
to 4.26% for the same period this year.

Provision for Loan Losses
     The provision for loan losses for the first nine months of 1998 was 
$105,000 versus $165,000 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 nine months ended September 30, 1998,
loan charge-offs net of recoveries declined to $14,000 from $253,000 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 nine months of 1998 totalled $3,143,000,
up $227,000 or approximately 8% from $2,916,000 reported in the corresponding
period last year.  This increase is due to net gains on securities of $1,858,000
reported for the nine months ended September 30, 1998 versus $1,501,000 reported
for the same period last year.  The Company has benefited significantly from the
stock market's strong performance during the first half of 1998.  The Company's
equity portfolio has yielded substantial realized and unrealized gains.  Net
unrealized gains in the equity securities portfolio still totalled $6.7 million
at September 30, 1998 despite the downturn in the stock market during the recent
quarter.  The improvement in net interest income due to the increase in 
securities gains was partially offset by a decrease of $75,000 in deposit 
account service fees and a decrease of $55,000 in other non-interest income.

Non-Interest Expense
     Non-interest expenses decreased by $1,064,000, or 10.3% to $9,246,000 in 
the first nine months of 1998 from $10,310,000 in the first nine months of 1997.

     Salaries and employee benefits, the largest component of non-interest
expense, decreased $362,000 or 6.2%, from $5,807,000 in the first nine months 
of 1997 to $5,445,000 in the first nine months of this year.  This reduction 
is due principally to a decrease of $313,000 in the Company's directors deferred
compensation plan expense and a decrease of $133,000 in the expense amount 
provided for payments to employees under the Bank's profit sharing and incentive
compensation bonus plans.  The expense related to the directors deferred
compensation plan is tied closely to the market value of the Company's common 
stock as previously indicated.

Non-Interest Expense (continued)

     Occupancy and equipment expenses were $1,549,000 for the nine months ended
September 30, 1998, essentially unchanged from $1,546,000 for the same period 
last year.

     There were no merger and acquisition related expenses incurred in the first
nine months of 1998.  In the first nine months of last year, the Bank incurred 
merger and acquisition related expenses of $156,000 in connection with its
acquisition of the Glendale Co-operative Bank.

     Bank charitable contributions for the first nine months of 1998 were 
$11,000 compared to $662,000 for the same period last year.  During the first 
nine months 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 $102,000 or 4.8%, from $2,139,000 for the nine
months ended September 30, 1997 to $2,241,000 for the nine months ended 
September 30, 1998.

Income Tax Expense
     The provision for federal and state income taxes increased to $4,884,000 
for the nine months ended September 30, 1998 from $4,326,000 for the same period
in 1997.  The Company's combined effective income tax rate for the first nine 
months of 1998 is 37.2% compared to 36.5% 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 relating to prior years.

     In addition, the Company in 1998 changed its tax year from an October 31 
fiscal year to a calendar year.  This change resulted in a lower state income 
tax rate for the Bank.  Since the tax rate for years beginning during 1997 and 
1998 was 11.32% and 10.91%, respectively, the Bank lowered its state income tax
rate.


Financial Condition
     Total assets at September 30, 1998 were $934.5 million, an increase of $9.1
million from $925.4 million at December 31, 1997.

     The Company's available for sale securities and trading securities
portfolios in the first nine months of 1998 decreased by $55.7 million and $20.1
million, respectively.  These decreases were offset by increases in short-
term investments of $60.2 million and an increase in the Bank's loan portfolio
of $24.6 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 $296.9 million at September 30, 1998
reflecting a net increase in loans of $24.6 million in the nine months ended
September 30, 1998.  This improvement results from an increase in loan 
originations.  Loan originations totalled $75.4 million in the nine months 
ended September 30, 1998, up approximately 87%, or $35.1 million from $40.3 
million in the first nine months of 1997.

     Total deposits were $811.7 million at September 30, 1998 essentially 
unchanged from $809.9 million at year end 1997.

     Total stockholders' equity rose to $110.4 million at September 30, 1998 
from $103.8 million at December 31, 1997.  Book value increased to $31.06 per 
share, from $29.06 per share at year end 1997.  The Company's book value per 
share has increased $2.81 or 9.9% since September 30, 1997.


Investments
     Total investments consisting of investment securities, short-term
investments, term federal funds sold and interest-bearing bank deposits 
equalled $619.8 million at September 30, 1998, down $15.9 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 $21.9 million as of September 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 $284.7 million at September 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 $24.6 million during the first nine
months of 1998, from $272.3 million at December 31, 1997 to $296.9 million at 
September 30, 1998.  Essentially all of the increase was in the residential 1-4
family category.  

     Loan originations increased to $75.4 million in the first nine months of 
1998 compared to $40.3 million in the first nine months of last year, an 
increase of $35.1 million or 87%.




NON-PERFORMING ASSETS
     The following table shows the composition of the Bank's non-performing 
assets at September 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 decreased from December 31, 1997 to September 30, 
1998 as noted in the table above.  The principal balance of non-accrual loans 
was $1,406,000, or approximately one-half of 1% of total loans and real estate
acquired through foreclosure was $53 thousand at September 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 September 30, 1998.





ALLOWANCE FOR LOAN LOSSES

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

                                                             Nine 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 September 30, 1998 the balance of the allowance for loan losses was 
$2,425,000 representing 172.5% 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 increased by $1.8 million to $811.7 million at
September 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:




                                             September 30,        December 31,

Recent Accounting Developments

     "Disclosures about Segments of an Enterprise and Related Information"
     In June 1997, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards ("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.

     "Employers' Disclosures about Pensions and Other Postretirement Benefits"
     Effective January 1, 1998, the Company adopted SFAS No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits, an amendment of 
SFAS Nos. 87, 88 and 106".  SFAS No. 132 standardizes the disclosure 
requirements for pensions and other postretirement benefits to the extent
practicable, requires additional information on changes in the benefit 
obligations and fair values of plan assets that will facilitate financial 
analysis, and eliminates certain disclosures required by SFAS Nos. 87, 88 
and 106.  The adoption of this pronouncement also requires restatement of
disclosures for earlier periods.

Recent Accounting Developments (continued)

     "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 September 30, 1998 the Bank had $145.0 million 
or 15.5% of total assets and $119.9 million or 12.8% 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 September 30, 1998, the Bank had a leverage
Tier I capital to total assets ratio of 10.16%, a Tier I capital to risk-
weighted assets ratio of 30.91% and a total capital to risk-weighted assets 
ratio of 32.72%.  The Company, on a consolidated basis, had ratios of leverage
Tier I capital to total assets of 10.60%, Tier I capital to risk-weighted assets
of 32.27% and total capital to risk-weighted assets of 34.08% at September 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 and environmental
systems (e.g., security systems, vaults, etc.) 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 completed testing of the Company's
existing computer hardware and has begun testing all of the Company's 
software applications and plans to substantially complete testing of the 
Company's mission critical internal information systems by December 31, 1998,
with the exception of its trust and items processing department systems.  The
hardware components for these systems is being replaced with Year 2000 compliant
equipment.  Delivery is expected in January 1999, and testing of these systems
is expected to be substantially completed by March 31, 1999.  Testing of the
Company's mission critical external information systems and non-mission 
critical systems are expected to be substantially completed by March 31, 1999,
and June 30, 1999, respectively.

     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.  Expenses to date total approximately $20,000.  Expenses for the remainder
of the Year 2000 project are estimated at $306,000.  This includes an estimated
$200,000 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 existing accounting policy.

      The expenditures of the project and the date on which the Bank plans to 
complete Year 2000 testing 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.

     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.  The data center's Y2K remediation  
efforts are also being monitored by the federal banking regulators.  The data
center's remediation progress to date is 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.  


Year 2000 (continued)

     Since there is no guarantee that the Company's data center or outside 
vendors will become Y2K compliant, the Company is developing a contingency plan.
The Company has drafted a contingency and business resumption plan that outlines
procedures to be followed in the event of the Year 2000 failure of mission 
critical systems, including the possibility of obtaining alternative vendors
or replacement systems.  This plan will be finalized in 1999.  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.   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.
