PART I

Item 1.  Business
Business of MASSBANK Corp.

General

     MASSBANK Corp. (the "Company") is a general business corporation
incorporated under the laws of the State of Delaware on August 11, 1986.
MASSBANK Corp. was organized for the purpose of becoming the holding company for
MASSBANK (the "Bank"). The Company is a one-bank holding company registered with
the Federal Reserve Board under the Bank Holding Company Act of 1956, as
amended. As of and since December 2, 1986, the effective date of the
reorganization whereby MASSBANK Corp. became the holding company for the Bank,
the Bank has been a wholly-owned subsidiary of MASSBANK Corp. The only office of
MASSBANK Corp., and its principal place of business, is located at the main
office of the Bank at 123 Haven Street, Reading, Massachusetts 01867.

     MASSBANK Corp. currently has no material assets other than its investment
in the Bank. The Company's primary business, therefore, is managing its
investment in the stock of the Bank. MASSBANK Corp. is classified by the
Commonwealth of Massachusetts as a securities corporation for tax purposes which
restricts its business to buying, selling, dealing in, or holding securities on
its own behalf. In the future, MASSBANK Corp. may become an operating company or
acquire banks or companies engaged in bank-related activities.

     MASSBANK Corp.'s principal sources of revenues on an unconsolidated basis,
which are used for the payment of dividends to stockholders and other purposes,
are dividends from MASSBANK and, to a lesser extent, interest income received
from its interest-bearing bank deposits. MASSBANK Corp.'s assets on an
unconsolidated basis at December 31, 1997 were represented by its investment in
the Bank of $101.1 million and other assets of $3.5 million. The Company's
liabilities consisted of loan indebtedness of $0.8 million and other liabilities
of less than $0.1 million. The proceeds of the loan were used to fund stock
purchases through the Employee Stock Ownership Plan ("ESOP"). See Note 18 to the
Consolidated Financial Statements for parent company only financial information.
At December 31, 1997 MASSBANK Corp. on a consolidated basis had total assets of
$925.4 million, deposits of $809.9 million, and stockholders' equity of $103.8
million which represents 11.2% of total assets. Book value per share at December
31, 1997 was $29.06.

     The Company does not own or lease any real or personal property. Instead it
intends to utilize during the immediate future the premises, equipment and
furniture of the Bank without the direct payment of rental fees to the Bank.

                                       2

Competition
     The primary business of MASSBANK Corp. currently is the ongoing business of
the Bank. Therefore, the competitive conditions faced by MASSBANK Corp.
currently are the same as those faced by the Bank. See "Business of MASSBANK -
Competition." In addition, many banks and financial institutions have formed
holding companies. It is likely that these holding companies will attempt to
acquire commercial banks, thrift institutions or companies engaged in
bank-related activities. MASSBANK Corp. would face competition in undertaking
any such acquisitions and in operating any such entity subsequent to its
acquisition.

Employees
     MASSBANK Corp. does not employ any persons; its management also serves as
management of, and is paid by, the Bank. See "Item 10 - Directors and Executive
Officers of the Registrant." MASSBANK Corp. utilizes the support staff of the
Bank from time to time and does not pay any separate salaries or expenses in
connection therewith.

Dividends
     MASSBANK Corp. paid total cash dividends of $0.885 per share in 1997
compared to $0.69 per share in 1996 and $0.5475 per share in 1995. The Company's
dividend payout ratios (cash dividends paid divided by net income) for 1997,
1996 and 1995 were 31%, 26% and 23%, respectively.

Stock Repurchase Program
     In July 1997, MASSBANK Corp. announced that its Board of Directors (the
"Board") had extended, for another year, the stock repurchase program which it
authorized in July, 1996. During 1997, the Company repurchased 46,807 of its
common shares under its ongoing repurchase program. This leaves 171,398 shares
available for repurchase in the current program.

Preferred Stock Purchase Rights
     In January 1990, the Board of Directors declared a dividend distribution of
one Preferred Stock Purchase Right for each outstanding share of MASSBANK Corp.
common stock. These Rights, which expire in January 2000, entitle their holders
to purchase from the Company one one-hundredth of a share (a "unit") of Series A
Junior Participating Cumulative Preferred Stock, par value $1.00 per share
("preferred stock") at a cash exercise price of $70.00 per unit, subject to
adjustment. The Rights will trade separately from the common stock and will
become exercisable when a person or group has acquired 15% or more of the
outstanding common stock, upon a tender offer that would result in a person or
group acquiring 15% or more of the outstanding common stock, or upon the
declaration by the Board of Directors that any person holding 10% or more of the
outstanding shares of common stock is an "adverse person".

     In the event a person or group acquires 15% or more of the outstanding
common stock or the Board of Directors declares a person an "adverse person",
each Right would entitle its holder (except if the holder is a person or group
described above) to receive upon exercise sufficient units of preferred stock to
equal a value of two times the exercise price of the Right. In the event the
Company is acquired in a merger or other business combination transaction or if
50% or more of the Company's assets or earning power is sold, each holder may
receive upon exercise common stock of the acquiring company having a market
value equal to two times the exercise price of the Right.

     The Rights are redeemable in whole, but not in part, by the Board of
Directors at a price of $.01 per Right any time before a person or group
acquires 15% or more of the outstanding common stock or the Board of Directors
declares a person an "adverse person".

Business of MASSBANK

General
     MASSBANK is a Massachusetts-chartered savings bank founded in 1872 as the
Melrose Savings Bank. In 1983, the Reading Savings Bank was merged into the
Melrose Savings Bank and the name of the resulting institution was changed to
MASSBANK for Savings. In 1986, the Bank converted from mutual to stock form of
ownership. In 1996, the name of the bank was changed from "MASSBANK for Savings"
to "MASSBANK".

     The Bank is primarily engaged in the business of attracting deposits from
the general public through its fifteen full service banking offices in Reading,
Chelmsford, Dracut, Everett, Lowell, Medford, Melrose, Stoneham, Tewksbury,
Westford and Wilmington, and originating residential and commercial real estate
mortgages, construction, and a variety of consumer loans. The Bank also invests
a significant portion of its funds in U.S. Treasury and Government agency
securities, mortgage-backed securities, federal funds sold, and other authorized
investments. The Bank's earnings depend largely upon net interest income, which
is the difference between the interest and dividend income derived by the Bank
from its loans and investments and the interest paid by the Bank on its deposits
and borrowed funds.

     The Bank's deposits are insured to applicable limits by the Bank Insurance
Fund ("BIF") of the Federal Deposit Insurance Corporation (the "FDIC") and
excess deposit accounts are insured by the Depositors Insurance Fund ("DIF"), a
private industry-sponsored deposit insurer.

     The Bank recognizes that loan and investment opportunities change over time
and that yields derived from such opportunities can vary significantly even when
the risks associated with those opportunities are comparable. By developing a
relatively liquid loan and investment portfolio, the Bank has attempted to
position itself so as to be able to take advantage of these changing
opportunities. Consequently, the Bank expects that the relative mix of its loan
and investment portfolios will change over time in response to changing market
conditions.

Acquisition
     On February 26, 1997, MASSBANK signed a definitive merger agreement to
purchase the Glendale Co-operative Bank ("Glendale") of Everett, Massachusetts.
Under the agreement, MASSBANK acquired all of the outstanding shares of Glendale
at a price of $28.00 per share, for an aggregate purchase price of $7.38
million.

     Glendale Co-operative Bank was a Massachusetts chartered co-operative bank
founded in 1928. Glendale operated a single banking office in the city of
Everett with total assets of $35.6 million. On July 21, 1997 MASSBANK completed
the acquisition. The transaction was accounted for as a purchase.

Market Area
     The Bank is headquartered in Reading, Massachusetts, which is located
approximately 15 miles north of Boston. The Bank's market area includes a
significant portion of eastern Massachusetts and is served by a network of 15
branch offices located on a broad arc stretching from Melrose and Everett in the
south, Dracut in the north, and Westford in the west.

     The Bank's general market area consists of the municipalities in which it
operates banking offices and all of the contiguous cities and towns.

     The Bank currently operates banking offices in the municipalities of
Chelmsford, Dracut, Everett, Lowell, Medford, Melrose, Reading, Stoneham,
Tewksbury, Westford and Wilmington.

Lending Activities
     The Bank's net loan portfolio totaled $270.0 million at December 31, 1997.

The following table sets forth information concerning the Bank's loan portfolio

</TABLE>

     Mortgage Lending. The Bank believes that the repayment periods of long-term
first mortgage loans, the general resistance of the public to variable rate
mortgage instruments and the highly competitive nature of the mortgage industry
require a prudent approach to mortgage lending. Consequently, as part of its
policy of generally attempting to match the maturities of its assets and its
liabilities, the Bank, over several years, has kept its mortgage loan portfolio
to a level at which the Bank believed there was an acceptable risk-to-reward
ratio in light of opportunities in the marketplace and the Bank's long-term
objectives. The Bank's net loan portfolio represented approximately 29.2% and
27.9% of the Company's total assets at December 31, 1997, and 1996,
respectively. The Bank realizes that this low level of loans with respect to
assets in relation to the securities portfolio results in a reduction in yield;
however, the Bank believes that this reduction would be more than offset in risk
and loss associated with lending during periods of economic decline. In today's
economic climate, the Bank would prefer a more even mix of loans and securities.
However, there remains a tremendous amount of competition for mortgages in the
Bank's area, and developing a quality loan portfolio takes time. The Bank
anticipates that its loan portfolio will grow slowly over the next few years.

Mortgage Lending (continued)

     Loan originations come from a number of sources, including referrals from
real estate brokers, walk-in customers, purchasers of property owned by existing
customers and refinancing for existing customers. In addition to actively
soliciting loan referrals, the Bank conducts an advertising and promotion
program, directed both toward the general public and real estate professionals
who might refer potential borrowers.

     Substantially all of the real estate loans originated by the Bank during
1997 were secured by real estate located in the Bank's primary lending area,
reflecting the Bank's commitment to serve the credit needs of the local
communities in which it operates banking offices.

     The Bank makes both conventional fixed and adjustable-rate loans on
one-to-four family residential properties for a term of ten to thirty years. The
Bank retains the 10, 12, 15 or 20 year fixed rate mortgages and adjustable rate
mortgages it originates for its own portfolio. Long-term (25 or 30 year) fixed
rate residential mortgages are generally sold in the secondary market.
Adjustable-rate mortgage loans ("ARMs") have rates that are re-set at either 1,
3, 5 or 10 year intervals and provide a margin over various mortgage indices.

     During the latter part of 1997, the Bank introduced a new Home Equity Line
of Credit product which it hopes will be well received by customers in the
months ahead. This new product offers customers a special introductory interest
rate of 7.25% which is fixed until the year 2000. Thereafter, the interest rate
will be variable and will be indexed to the 13 week (91 day) Treasury Bill
auction rate plus a margin of 3.25%. This indexed variable rate has historically
responded more favorably to movements in market interest rates than the PRIME
RATE used by many financial institutions and should, therefore, be more
attractive to bank customers.

     In the last few years, the Bank has instituted several other new loan
programs which have been well received by customers. It instituted a program
featuring a 5/1 and 7/1 year ARM product with an initial fixed rate for 5 or 7
years and a 1 year adjustable rate thereafter. A special First Time Home Buyers
Program has also been instituted featuring a discounted 7/1 ARM. This program is
designed for first-time home buyers meeting certain income and property location
restrictions. In 1996, the Bank introduced the "Home Town Advantage" mortgage
program which has produced some good results. This new program offers homebuyers
a (0.125) percent discount on their mortgage rate if they purchase residential
property located in one of the communities where the bank operates a banking
office.

     At December 31, 1997, 1-4 family residential mortgage loans totaled $244.5
million, or 89.8% of the total loan portfolio, compared to $218.6 million, or
87.6% of the total loan portfolio, at December 31, 1996. Residential mortgage
loan originations amounted to $50.0 million during 1997, an increase of 19.3%
from $41.9 million in 1996. Origination volumes are sensitive to interest rates
and are affected by the interest rate environment. The prevailing low interest
rates in 1997 encouraged many borrowers to refinance. This resulted in higher
mortgage loan originations for the Bank.

     The Bank also originates mortgage loans secured by commercial or investment
property such as multifamily housing, strip shopping centers, office buildings
and retail buildings. At December 31, 1997, commercial and multifamily real
estate mortgages and construction loans totaled approximately $4.3 million, or
1.6% of the total loan portfolio, compared to $5.5 million, or 2.2% of the total
loan portfolio, at December 31, 1996. In 1997, commercial and multifamily real
estate mortgage loan originations amounted to $0.3 million.

Mortgage Lending (continued)

     The total amount of first mortgage loans held by the Bank at December 31,
1997 was $248.8 million as indicated in the maturity distribution table
appearing on the previous page. Of this amount, $53.9 million was subject to
interest rate adjustments. The remaining $194.9 million in fixed rate mortgage
loans represents 21.1% of the Company's total assets.

     Fees received for originating loans and related direct incremental loan
origination costs are offset and the resulting net amount is deferred and
amortized over the life of the related loans using the level-yield method.

     The Bank also receives fees and charges relating to existing loans,
primarily late charges and prepayment penalties.

     Other Loans. The Bank makes a variety of consumer loans and had a consumer
loan portfolio of approximately $23.5 million at December 31, 1997 representing
8.6% of the Bank's total loan portfolio. Of this amount $8.9 million or 3.3% of
the total loan portfolio are education loans made under the Massachusetts Higher
Education Assistance Corporation. The Bank may sell education loans in the
future.

     The balance of the Bank's consumer loan portfolio consists of home equity
lines of credit and installment consumer credit contracts such as automobile
loans, home improvement loans and other secured and unsecured financings. These
loans totaled $14.5 million at December 31, 1997, representing 5.3% of the
Bank's total loan portfolio.

     At December 31, 1997, the Bank had only $36 thousand in outstanding loans
to commercial enterprises not secured by real estate.

     Loan Approval. The Bank's loan approval process for all loans generally
includes a review of an applicant's financial statements, credit history,
banking history and verification of employment. For mortgage loans, the Bank
generally obtains an independent appraisal of the subject property. The Bank has
a formal lending policy approved by the Board of Directors of the Bank which
delegates levels of loan approval authority to Bank personnel. All loans in
excess of established limits require approval of the Bank's Board of Directors.

     The Bank issues commitments to prospective borrowers to make loans subject
to certain conditions for generally up to 60 days. The interest rate applicable
to the committed loans is usually the rate in effect at the time the application
fee is paid. At December 31, 1997, the Bank had issued commitments on
residential first mortgage loans totaling $4,090,000, and had commitments to
advance funds on construction loans and unused credit lines, including unused
portions of home equity lines of credit, of $496,000 and $19,445,000,
respectively.

     Loan Delinquencies. It is the Bank's policy to manage its loan portfolio so
as to recognize problem loans at an early stage and thereby minimize loan
losses. Loans are considered delinquent when any payment of principal or
interest is 30 days or more past due. The Bank generally commences collection
procedures, however, when accounts are 15 days past due. It is the Bank's
practice to generally discontinue accrual of interest on all loans for which
payments are more than 90 days past due. Loans delinquent for 90 or more days,
as shown in the table on the following page, totaled $1,771,000 at December 31,
1997.

Real Estate Acquired through Foreclosure.
     Real estate acquired through foreclosure is comprised of foreclosed
properties where the Bank has actually received title and loans determined to be
substantially repossessed. Real estate loans that are substantially repossessed
include only those loans for which the Bank has taken possession of the
collateral but has not completed legal foreclosure proceedings. Loan losses
arising from the acquisition of such properties are charged against the
allowance for loan losses. Real estate acquired through foreclosure is recorded
at the lower of the carrying value of the loan or the fair value of the property
constructively or actually received, less estimated costs to sell the property
following foreclosure. Operating expenses and any subsequent provisions to
reduce the carrying value to fair value are charged to current period earnings.
Gains and losses upon disposition are reflected in earnings as realized. As of
year-end 1997, MASSBANK had zero real estate acquired through foreclosure on its
balance sheet.

Allowance for Loan Losses.
     The allowance for loan losses is increased by provisions charged to
operations based on management's assessment of many factors including the risk
characteristics of the portfolio, underlying collateral, current and anticipated
economic conditions that may affect the borrower's ability to pay, and trends in
loan delinquencies and charge-offs. Realized losses, net of recoveries, are
charged directly to the allowance. While management uses the information
available in establishing the allowance for loan losses, future adjustments to
the allowance may be necessary if economic conditions differ substantially from
the assumptions used in making the evaluation. In addition, various regulatory
agencies, as an integral part of their examination process, periodically review
the Bank's allowance for loan losses. Such agencies may require the Bank to
recognize additions to the allowance based on judgments different from those of
management.

The following table sets forth the activity in the allowance for loan losses
during the years indicated:

Investment Activities

      The Bank believes that investment opportunities in United States
Government, corporate and other securities are at times more attractive than the
opportunities present in the loan market. As compared to loans, these
investments of the Bank are generally shorter-term and hence more liquid, are
subject to lower risk of loss, and present an opportunity for appreciation. In
addition, these investments often permit the Bank to better match the maturities
of its assets and its liabilities.

     The Bank's investment portfolio is managed by its officers in accordance
with an investment policy approved by the Bank's Board of Directors. The
objectives of that policy are to provide a level of liquidity, earnings and
diversification consistent with the exercise of prudent investment judgment. The
policy authorizes the senior management of the Bank to make and execute
investment decisions and requires that those persons report all investment
transactions to the Bank's Board of Directors at each of its regular meetings.
In addition, management is required to report all gains or losses on all
securities transactions at each meeting of the Bank's Board of Directors.
Purchases and sales of securities by the Bank are generally required to be made
on a competitive basis and all investments must be permitted by applicable law.

     The Bank invests in a wide variety of securities and obligations,
including: Federal funds sold (which are sold only to institutions included on
the Bank's internally-prepared approved list of adequately capitalized
institutions); commercial paper and bankers' acceptances; United States Treasury
and Government agency obligations; United States agency guaranteed and other
mortgage-backed securities; investment grade corporate debt securities
(generally limited to those rated A or better by Standard & Poor's); mutual
funds; and equity securities traded on a national securities exchange or quoted
on the NASDAQ System.

     Under the investment policy management determines the appropriate
classification of securities at the time of purchase. Those securities that the
Company has the intent and the ability to hold to maturity are classified as
securities held to maturity and are carried at amortized historical cost.

     Those securities held for indefinite periods of time and not intended to be
held to maturity are classified as available for sale. Securities held for
indefinite periods of time include securities that management intends to use as
part of its asset/liability management strategy and that may be sold in response
to changes in interest rates, changes in prepayment risk, the need to increase
regulatory capital and other similar factors. Income on debt securities
available for sale is accrued and included in interest and dividend income. The
specific identification method is used to determine realized gains and losses on
sales of securities available for sale which are also reported in non-interest
income under the caption "gains (losses) on securities." When a security suffers
a loss in value which is considered other than temporary, such loss is
recognized by a charge to earnings.

Investment Activities (continued)

     Investments classified as trading securities are stated at market with
unrealized gains or losses included in earnings. Income on debt trading
securities is accrued and included in interest and dividend income. All of the
Company's mortgage-backed securities are currently classified as available for
sale. At times of low loan demand, short-term mortgage-backed securities may be
used as substitutes for loans as certain of their financial characteristics are
very similar to short-term mortgage loans.

     At December 31, 1997, the Company's investments, which consists of
securities held to maturity, securities available for sale (including
mortgage-backed securities), trading securities, short-term investments, term
federal funds sold and interest-bearing deposits in banks totaled $635.7
million, representing 68.7% of the Company's total assets.

(1)  Yields on tax exempt obligations have been computed on a tax equivalent
     basis.

(2)  Mortgage-backed securities are shown at their contractual maturity, but are
     expected to have shorter lives due to scheduled payments and prepayments.

     At December 31, 1997, the Company did not have an investment in any issuer
(other than securities of the U.S. government) in excess of 10% of stockholders
equity.

Deposits and Other Sources of Funds

     General. Deposits have been the primary source of funds of the Bank for
making investments and loans. In addition to deposits, the Bank's other major
sources of funds are derived from amortization and prepayment of loans and
mortgage-backed securities, from sales or maturities of securities, and from
operations. Deposit flows can vary significantly and are influenced by
prevailing interest rates, money market conditions, economic conditions and
competition. The Bank can respond to changing market conditions and competition
through the pricing of its deposit accounts. Management can control the level of
its deposits to a significant degree through its pricing policies. Another
important factor in attracting deposits is convenience. In addition to the
Bank's fifteen conveniently located banking offices, customers can access
accounts through the Bank's ATM network. The Bank is a member of the Transaxion
("TX"), New York Cash Exchange ("NYCE") and CIRRUS System, Inc. ("CIRRUS")
networks which allow access to ATMs in over 100,000 locations worldwide.

     Deposits. A substantial amount of the Bank's deposits are derived from
customers who live or work within the Bank's market area. The Bank does not
solicit deposits through any outside agents. The Bank's deposits consist of
regular, silver and smart savings accounts, special notice accounts, NOW and
Super NOW accounts, business checking accounts, money market deposit accounts,
IRA and Keogh accounts, and term deposit accounts.

     The Bank's deposits increased by $21.5 million or 2.7% during the twelve
months ended December 31, 1997, from $788.4 million at year end 1996 to $809.9
million at the end of 1997. The increase is attributable to the $29.8 million in
deposits acquired in connection with the Glendale purchase. Also, in 1997, the
Bank experienced some modest deposit outflow due to the strong performance of
the stock market and mutual funds which were both fierce competitors for the
savers' dollars.

     Borrowed Funds. From time to time the Bank has obtained funds through
repurchase agreements with its customers and federal funds purchased. The Bank
also has the ability, although it has never exercised it, to borrow from the
Federal Reserve Bank and The Depositors Insurance Fund, Inc. The Company did not
have any borrowed funds in 1997 or 1996.

Investment Management and Trust Services

     The Bank's Trust and Investment Services Division offers a variety of
investment, trust and estate planning services and also serves as Trustee,
Executor, and Executor's Agent for bank customers.

     As of December 31, 1997 the Trust Division had approximately $30.2 million
(market value) of assets in custody and under management.

Competition

     The Bank faces substantial competition both in originating loans and in
attracting deposits. Competition in originating loans comes primarily from other
thrift institutions, commercial banks, credit unions and mortgage banking
companies. The Bank competes for loans principally on the basis of interest
rates and loan fees, the types of loans originated and the quality of services
provided to borrowers.

     In attracting deposits, the Bank's primary competitors are other thrift
institutions, commercial banks, mutual funds and credit unions located in its
market area. The Bank's attraction and retention of deposits depend on its
ability to provide investment opportunities that satisfy the requirements of
customers with respect to rate of return, liquidity, risk and other factors. The
Bank attracts a significant amount of deposits through its branch offices
primarily from the communities in which those branch offices are located. The
Bank competes for these deposits by offering competitive rates, convenient
branches and ATM locations and convenient business hours.

Supervision and Regulation of the Company and its Subsidiaries

     The Bank is in a heavily regulated industry. As a Massachusetts-chartered
savings bank whose deposits are insured by the FDIC and The Depositors Insurance
Fund, the Bank is subject to regulation, supervision and examination by federal
and state regulatory authorities, including, but not limited to the FDIC, the
Massachusetts Commissioner of Banks and The Depositors Insurance Fund. This
Federal and State regulation is for the benefit of borrowers, depositors and the
respective deposit insurance funds and is not for the benefit of the Bank, the
Company or its stockholders.

     The Bank is subject to extensive federal and state statutes, regulations,
policies and standards regarding virtually all aspects of its operations,
including capital adequacy, reserves, liquidity, payment of dividends,
transactions with affiliates, loans to officers, directors, principal
shareholders and their related interests, mergers, acquisitions and changes in
controlling ownership, establishment, relocation and closure of branch banking
offices, community reinvestment, fair lending, fair credit reporting, real
estate settlement procedures, funds availability, disclosure to consumers and
financial accounting, reporting and recordkeeping. In the event the Bank did not
operate in accordance with FDIC statutes, regulations or policies, the FDIC has
authority to terminate insurance of the Bank's deposit accounts and the FDIC and
the Commissioner of Banks have authority to impose other sanctions for such
non-compliance. For a discussion of the Bank's capital adequacy, see Note 15 of
Notes to Consolidated Financial Statements appearing in the Company's 1997
Annual Report to Stockholders, which is incorporated herein by reference.

     In addition, as a bank holding company, the Company is subject to
supervision, examination and regulation by the Board of Governors of the Federal
Reserve System and is subject to statutes, regulations and policies relating to,
among other things, mergers, acquisitions and changes in controlling ownerships,
non-bank activities and subsidiaries, capital adequacy, the payment of
dividends, the tying of the sale or pricing of products or services of bank and
nonbank subsidiaries, and the provision of financial and managerial support of
its subsidiary bank.

     The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") made significant changes in federal laws governing depository
institutions and the FDIC. Among other changes, FDICIA requires federal bank
regulatory agencies to take "prompt corrective action" with respect to banks
that do not meet applicable regulatory capital requirements. In addition, FDICIA
prohibits state chartered banks from engaging, as principals, in activities such
as equity investments and insurance underwriting, which are not permissible for
national banks, unless the FDIC has determined that the activity would pose no
significant risk to the Bank Insurance Fund and the state bank is in compliance
with applicable capital standards. An insured state bank, such as MASSBANK, may
to the extent permitted by the FDIC, acquire and retain ownership of common or
preferred stock listed on a national securities exchange, provided that the
insured state bank made or maintained an investment in such securities during
the period beginning on September 30, 1990 and ending on November 26, 1991,
which MASSBANK did, and provided further that the aggregate amount of the
investment does not exceed 100 percent of the Bank's capital. At December 31,
1997, the Bank had marketable equity securities and investment in mutual funds
with a market value of approximately $21.4 million, representing 21.3% of the
Bank's equity capital. In addition, FDICIA limits the aggregate amount a bank
may lend to its directors, executive officers and principal shareholders and
their related interests, prohibits depository institutions that are not well
capitalized from accepting brokered deposits without an express waiver from the
FDIC, requires uniform disclosures to consumers of the terms of bank deposit
accounts, and requires banks to give regulators and bank customers advance
notice of branch closings. FDICIA also establishes a system of risk-based
deposit insurance assessments that takes a bank's capital level and supervisory
risk characteristics into account in calculating the amount of its federal
deposit insurance assessment.

     FDICIA imposes annual audit and reporting requirements on banking
organizations with more than $500 million in total assets. Finally, the FDICIA
requires the FDIC and the other Federal bank regulatory agencies to issue
regulatory standards to govern various aspects of bank operations including real
estate lending, executive compensation, loan documentation, credit underwriting,
interest rate risk exposure, and asset growth.

     In 1994, the Riegle-Neal Interstate Banking and Branching Act of 1994 (the
"Interstate Banking Act") was enacted. The Interstate Banking Act's provisions,
among other things: (i) permit bank holding companies, under certain
circumstances, to acquire control of banks in any state, subject to (a)
specified maximum national and state deposit concentration limits; (b) any
applicable state law provisions requiring that the acquired bank has to have
been in existence for a specified period of up to 5 years; (c) any applicable
nondiscriminatory state provisions that make an acquisition of a bank contingent
upon a requirement to hold a portion of such bank's assets available for call by
a state-sponsored housing entity; and (d) applicable anti-trust laws; (ii)
authorize interstate mergers by banks in different states, including branching
through bank mergers, beginning June 1, 1997, subject to the provisions noted in
(i) and to any state laws that "opt-in" as of an earlier date or "opt-out" of
the provisions entirely; (iii) authorize states to enact legislation permitting
interstate de novo branching; and (iv) provide for parity of treatment for
foreign bank branch activities.

     In 1996, Massachusetts enacted legislation implementing the provisions of
the Interstate Banking Act. In the new legislation, Massachusetts authorized
immediate "opt-in" to interstate banking. Thus, the 1996 legislation
substantially facilitates the geographic expansion of banking by Massachusetts
and out-of-state banks.


                                       20

     The 1996 legislation also allows out-of-state banks to establish and
maintain branches through a merger or consolidation with or the purchase of
assets or stock of any Massachusetts bank or through de novo branch
establishment or purchase of a branch without purchase of the bank which owns
the branch, in Massachusetts, provided that such out-of-state bank is expressly
authorized to do so by the laws of the state under which it is organized. The
1996 legislation also allows Massachusetts banks to establish and maintain
branches through a merger or consolidation with or by the purchase of the whole
or any part of the assets or stock of any out-of-state bank or through de novo
branch establishment in any other state other than Massachusetts. Finally, the
1996 legislation prohibits the establishment of bank holding companies and
acquisition of banks and bank holding companies by Massachusetts and
out-of-state bank holding companies if the Massachusetts bank to be acquired has
been in existence less than 3 years or if, after such acquisition, the bank
holding company would control 28% of the deposits in Massachusetts (until 1998,
when the deposit limitation is increased to 30%).

     From time to time the U.S. Congress and the Massachusetts Legislature adopt
legislation and the Federal and State bank regulatory agencies issue regulations
and policies that may significantly affect the operations of the Bank and the
Company. No assurance can be given as to whether additional legislation will be
enacted or whether additional regulations or policies will be issued or as to
the effect any such legislation, regulations or policies may have on the Bank or
the Company.

Employees

     MASSBANK Corp. utilizes the support staff of the Bank from time to time
without the payment of any fees. No separate compensation is being paid to the
executive officers of MASSBANK Corp., all of whom are executive officers of the
Bank and receive compensation as such. As of December 31, 1997, the Bank had 150
full-time employees, including 30 officers, and 62 part-time employees. None of
the Bank's employees is represented by a collective bargaining group, and
management believes that its employee relations are good. The Bank provides its
employees with formal training in product knowledge, sales techniques, fair
lending, and motivation. In addition, each supervisor at the Bank receives
management training before assuming his or her supervisory duties and
periodically thereafter. The Bank maintains a comprehensive employee benefit
program for qualified employees that includes a qualified pension plan, an
Employee Stock Ownership Plan (ESOP), health and dental insurance, life and
long-term disability insurance and tuition assistance.

conduct of its business to acquire a proprietary interest in the Company. It is

      (b) Powers of Committee. The Committee shall have the power and authority
to grant Awards consistent with the terms of the Plan, including the power and
authority:

            (i) to select the officers, other employees and directors of the
      Company and its Subsidiaries to whom Awards may from time to time be
      granted;

            (ii) to determine the time or times of grant, and the extent, if

      Appreciation Rights, Restricted Stock, Unrestricted Stock and Performance
      Shares, or any combination of the foregoing, granted to any one or more

            (v) to accelerate the exercisability or vesting of all or any 
      portion of any Award;

            (vi) to determine whether, to what extent, and under what
      circumstances Stock and other amounts payable with respect to an Award
      shall be deferred either automatically or at the election of the
      participant and whether and to what extent the Company shall pay or credit
      amounts equal to interest (at rates determined by the Committee) or
      dividends or deemed dividends on such deferrals; and

            (vii) to adopt, alter and repeal such rules, guidelines and
      practices for administration of the Plan and for its own acts and
      proceedings as it shall deem advisable; to interpret the terms and

                                      3
<PAGE>   4
      related Award Agreements); to make all determinations it deems advisable
      for the administration of the Plan; to decide all disputes arising in
      connection with the Plan; and to otherwise supervise the administration of
      the Plan.

      All decisions and interpretations of the Committee shall be binding on all
persons, including the Company and Plan participants.

SECTION 3.  SHARES ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION.

      (a) Shares Issuable. The maximum number of shares of Stock reserved and
available for issuance under the Plan shall be 190,000, subject to adjustment in
accordance with Section 3(b) below. For purposes of this limitation, the shares
of Stock underlying any Awards which are forfeited, cancelled, reacquired by the
Company, satisfied without the issuance of Stock or otherwise terminated (other
than by exercise) shall be added back to the shares of Stock available for
issuance under the Plan so long as the Plan participants to whom such Awards had
been previously granted received no benefits of ownership of the underlying
shares of Stock to which the Award related. Subject to such overall limitation,
shares may be issued up to such maximum number pursuant to any type or types of
Award, including Incentive Stock Options. No more than 70,000 shares may be
issued to any one individual in the form of Options and Stock Appreciation
Rights in any period of three consecutive years, subject to the adjustment of
such number of shares in accordance with Section 3(b) below. Shares issued under
the Plan may be authorized but unissued shares or shares reacquired by the
Company. Upon the exercise of a Stock Appreciation Right settled in stock, the
right to purchase an equal number of shares of Common Stock covered by a related
Stock Option, if any, shall be deemed to have been surrendered and will no
longer be exercisable, and said number of shares shall no longer be available
under the Plan.

      (b) Stock Dividends, Mergers, Etc. In the event of a stock dividend, stock
split or similar change in capitalization affecting the Stock, the Committee
shall make appropriate adjustments in (i) the number and kind of shares of stock
or securities that may be issued pursuant to the Plan or on which Awards may
thereafter be granted, (ii) the number and kind of shares remaining subject to
outstanding Awards, and (iii) the option or purchase price in respect of such
shares. In the event of any merger, consolidation, dissolution or liquidation of
the Company, the Committee in its sole discretion (and without the consent of
the optionee) may, as to any outstanding Awards, make such substitution
(including the substitution of shares of capital stock of any other entity) or
adjustment in the aggregate number of shares reserved for issuance under the
Plan and in the number and purchase price (if any) of shares subject to such
Awards as it may determine and as may be permitted by the terms of such
transaction, or accelerate, amend or terminate such Awards upon such terms and
conditions as it shall provide (which, in the case of the termination of the
vested portion of any Award, shall require payment or other consideration which
the Committee deems equitable in the circumstances), subject, however, to the
provisions of Section 14.


                                      4
<PAGE>   5
      (c) Substitute Awards. The Committee may grant Awards under the Plan in
substitution for stock and stock based awards held by employees of another
corporation who concurrently become employees of the Company or a Subsidiary as
the result of a merger or consolidation of the employing corporation with the
Company or a Subsidiary or the acquisition by the Company or a Subsidiary of
property or stock of the employing corporation. The Committee may direct that
the substitute awards be granted on such terms and conditions as the Committee
considers appropriate in the circumstances.

SECTION 4.  ELIGIBILITY.

      Participants in the Plan will be such officers and other employees of the
Company and its Subsidiaries who are responsible for or contribute to the
management, growth or profitability of the Company and its Subsidiaries and who
are selected from time to time by the Committee, in its sole discretion.
Non-Employee Directors are also eligible to participate in the Plan but only to
the extent provided in Section 5(c) and Section 8(c) below.

SECTION 5.  STOCK OPTIONS.

      Any Stock Option granted under the Plan shall be in such form as the
Committee may from time to time approve.

      Stock Options granted under the Plan may be either Incentive Stock Options
or Non-Qualified Stock Options. To the extent that any option does not qualify
as an Incentive Stock Option, it shall constitute a Non-Qualified Stock Option.

      No Incentive Stock Option shall be granted under the Plan after January
17, 2004.

      (a) Stock Options Granted to Employees. The Committee in its discretion
may grant Stock Options to employees of the Company or any Subsidiary. Stock
Options granted to employees pursuant to this Section 5(a) shall be subject to
the following terms and conditions and shall contain such additional terms and
conditions, not inconsistent with the terms of the Plan, as the Committee shall
deem desirable:

            (i) Exercise Price. The per share exercise price of a Stock Option
      shall be determined by the Committee at the time of grant but shall be, in
      the case of Incentive Stock Options, not less than 100% of Fair Market
      Value on the date of grant. If an employee owns or is deemed to own (by
      reason of the attribution rules applicable under Section 424(d) of the
      Code) more than 10% of the combined voting power of all classes of stock
      of the Company or any Subsidiary or parent corporation and an Incentive
      Stock Option is granted to such employee, the option price shall be not
      less than 110% of Fair Market Value on the grant date.


                                      5
<PAGE>   6
            (ii) Option Term. The term of each Stock Option shall be fixed by
      the Committee, but no Incentive Stock Option shall be exercisable more
      than ten years after the date the option is granted. If an employee owns
      or is deemed to own (by reason of the attribution rules of Section 424(d)
      of the Code) more than 10% of the combined voting power of all classes of
      stock of the Company or any Subsidiary or parent corporation and an
      Incentive Stock Option is granted to such employee, the term of such
      option shall be no more than five years from the date of grant.

            (iii) Exercisability; Rights of a Shareholder. Stock Options shall
      become vested and exercisable at such time or times, whether or not in
      installments, as shall be determined by the Committee at or after the
      grant date. The Committee may at any time accelerate the exercisability of
      all or any portion of any Stock Option. An optionee shall have the rights
      of a shareholder only as to shares acquired upon the exercise of a Stock
      Option and not as to unexercised Stock Options.

            (iv) Method of Exercise. Stock Options may be exercised in whole or
      in part, by giving written notice of exercise to the Company, specifying
      the number of shares to be purchased. Payment of the purchase price may be
      made by one or more of the following methods:

                  (A) In cash, by certified or bank check or other instrument
            acceptable to the Committee;

                  (B) Through the delivery (or attestation to the ownership) of
            shares of Stock that have been purchased by the optionee in the open
            market or that have been held by the optionee for at least six
            months and are not then subject to restrictions under any Company
            plan, if permitted by the Committee, in its discretion. Such
            surrendered shares shall be valued at Fair Market Value on the
            exercise date; or

                  (C) By the optionee delivering to the Company a properly
            executed exercise notice together with irrevocable instructions to a
            broker to promptly deliver to the Company cash or a check payable
            and acceptable to the Company to pay the option purchase price;
            provided that in the event the optionee chooses to pay the option
            purchase price as so provided, the optionee and the broker shall
            comply with such procedures and enter into such agreements of
            indemnity and other agreements as the Committee shall prescribe as a
            condition of such payment procedure.

      The delivery of certificates representing shares of Stock to be purchased
      pursuant to the exercise of a Stock Option will be contingent upon receipt
      from the Optionee (or a purchaser acting in his stead in accordance with
      the provisions of the Stock Option) by the Company of the full purchase
      price for such shares and the fulfillment of any other

                                      6
<PAGE>   7
      requirements contained in the Stock Option or applicable provisions of
      laws. Payment instruments will be received subject to collection. In the
      event an optionee chooses to pay the purchase price by previously-owned
      shares of Stock through the attestation method, the shares of Stock
      transferred to the optionee upon the exercise of the Stock Option shall be
      net of the number of shares attested to.

            (v) No Stock Option shall be transferable by the optionee otherwise
      than by will or by the laws of descent and distribution and all Stock
      Options shall be exercisable, during the optionee's lifetime, only by the
      optionee. Notwithstanding the foregoing, the Committee, in its sole
      discretion, may provide in an Award Agreement that the optionee may
      transfer, without consideration for the transfer, his Non-Qualified Stock
      Options to members of his immediate family, to trusts for the benefit of
      such family members and to partnerships in which such family members are
      the only partners; provided that the transferee agrees in writing with the
      Company to be bound by all of the terms and conditions of this Plan and
      the applicable Award Agreement.

            (vi) Termination by Death. If any optionee's employment by the
      Company and its Subsidiaries terminates by reason of death, the Stock
      Option may thereafter be exercised, to the extent exercisable at the date
      of death, by the legal representative or legatee of the optionee, for a
      period of one year (or such shorter period as the Committee shall specify
      at the time of grant or such longer period as the Committee shall specify
      at any time) from the date of death, or until the expiration of the stated
      term of the Option, if earlier.

            (vii) Termination by Reason of Disability or Normal Retirement.

                  (A) Any Stock Option held by an optionee whose employment by
            the Company and its Subsidiaries has terminated by reason of
            Disability may thereafter be exercised, to the extent it was
            exercisable at the time of such termination, for a period of one
            year (or such shorter period as the Committee shall specify at the
            time of grant or such longer period as the Committee shall specify
            at any time) from the date of such termination of employment, or
            until the expiration of the stated term of the Option, if earlier.

                  (B) (1) Any Non-Qualified Stock Option held by an optionee
            whose employment by the Company and its Subsidiaries has terminated
            by reason of Normal Retirement may thereafter be exercised, to the
            extent it was exercisable at the time of such termination, for a
            period of one year (or such shorter period as the Committee shall
            specify at the time of grant or such longer period as the Committee
            shall specify at any time) from the date of such termination of
            employment, or until the expiration of the stated term of the
            Option, if earlier.


                                      7
<PAGE>   8
                        (2) Any Incentive Stock Option held by an optionee whose
            employment by the Company and its Subsidiaries has terminated by
            reason of Normal Retirement may thereafter be exercised, to the
            extent it was exercisable at the time of such termination, for a
            period of three months (or such shorter period as the Committee
            shall specify at the time of grant or such longer period as the
            Committee shall specify at any time) from the date of such
            termination of employment, or until the expiration of the stated
            term of the Option, if earlier.

                  (C) The Committee shall have sole authority and discretion to
            determine whether a participant's employment has been terminated by
            reason of Disability or Normal Retirement.

                  (D) Except as otherwise provided by the Committee at the time
            of grant, the death of an optionee during a period provided in this
            Section 5(a)(vii) for the exercise of a Non-Qualified Stock Option
            (or during the final year of such period if longer than one year),
            shall extend such period for one year following death, subject to
            termination on the expiration of the stated term of the Option, if
            earlier.

            (viii) Termination for Cause. If any optionee's employment by the
      Company and its Subsidiaries has been terminated for Cause, any Stock
      Option held by such optionee shall immediately terminate and be of no
      further force and effect; provided, however, that the Committee may, in
      its sole discretion, provide that such Stock Option can be exercised for a
      period of up to three months from the date of termination of employment or
      until the expiration of the stated term of the Option, if earlier.

            (ix) Other Termination. Unless otherwise determined by the
      Committee, if an optionee's employment by the Company and its Subsidiaries
      terminates for any reason other than death, Disability, Normal Retirement
      or for Cause, any Stock Option held by such optionee may thereafter be
      exercised, to the extent it was exercisable on the date of termination of
      employment, for a period of three months (or such shorter period as the
      Committee shall specify at the time of grant or such longer period as the
      Committee shall specify at any time) from the date of termination of
      employment or until the expiration of the stated term of the Option, if
      earlier.

            (x) Annual Limit on Incentive Stock Options. To the extent required
      for "incentive stock option" treatment under Section 422 of the Code, the
      aggregate Fair Market Value (determined as of the time of grant) of the
      Stock with respect to which Incentive Stock Options granted under this
      Plan and any other plan of the Company or its Subsidiaries become
      exercisable for the first time by an optionee during any calendar year
      shall not exceed $100,000.


                                      8
<PAGE>   9
            (xi) Form of Settlement. Shares of Stock issued upon exercise of a
      Stock Option shall be free of all restrictions under this Plan, except as
      otherwise provided in this Plan.

      (b) Reload Options. At the discretion of the Committee, Options granted
under Section 5(a) may include a so-called "reload" feature pursuant to which an
optionee exercising an Option and paying the purchase price by the delivery of a
number of shares of Stock in accordance with Section 5(a)(iv)(B) hereof would
automatically be granted an additional Option (with an exercise price equal to
the Fair Market Value of the Stock on the date the additional Option is granted
and with the same expiration date as the original Option being exercised, and
with such other terms as the Committee may provide) to purchase that number of
shares of Stock equal to the number delivered to pay the purchase price in
connection with the exercise of the original Option.

      (c)   Stock Options Granted to Non-Employee Directors.

            (i) Grant of Options. The Committee in its discretion may grant
      Non-Qualified Stock Options to Non-Employee Directors subject to the
      following terms and conditions (it being noted that under the current
      Rules under the Act, such grant may result in the members of the Committee
      ceasing for a period of time to be Disinterested Persons and the Plan
      ceasing to be qualified under Rule 16b-3).

            (ii) Exercise Price. The exercise price per share for the Stock
      covered by a Stock Option granted pursuant to this Section 5(c) shall be
      equal to the Fair Market Value of the Stock on the date the Stock Option
      is granted.

            (iii) Exercise; Termination; Non-transferability.

                  (A) No Option granted under this Section 5(c) may be exercised
            before the first anniversary of the date upon which it was granted;
            provided, however, that any Option so granted shall become
            exercisable upon the termination of service of the Non-Employee
            Director because of Disability or death or upon the occurrence of a
            Change in Control as set forth in Section 14 hereof. No Option
            issued under this Section 5(c) shall be exercisable after the
            expiration of ten years from the date upon which such Option is
            granted.

                  (B) The rights of a Non-Employee Director in an Option granted
            under Section 5(c) shall terminate three months after such Director
            ceases to be a Director of the Company or the specified expiration
            date, if earlier; provided, however, that if the Non-Employee
            Director resigns, is not re-nominated for election or is removed as
            a Director and the Committee determines that the primary reason for
            such resignation, failure to re-nominate or removal would

                                      9
<PAGE>   10
            constitute Cause, then the rights shall terminate immediately on the
            date on which he ceases to be a Director.

                  (C) No Stock Option granted under this Section 5(c) shall be
            transferable by the optionee otherwise than by will or by the laws
            of descent and distribution, and Options granted under this Section
            5(c) shall be exercisable, during the optionee's lifetime, only by
            the optionee. Notwithstanding the foregoing, the Committee, in its
            sole discretion, may provide in an Award Agreement that the optionee
            may transfer, without consideration for the transfer, his Stock
            Options to members of his immediate family, to trusts for the
            benefit of such family members and to partnerships in which such
            family members are the only partners; provided that the transferee
            agrees in writing with the Company to be bound by all of the terms
            and conditions of this Plan and the applicable Award Agreement. Any
            Option granted to a Non-Employee Director and outstanding on the
            date of his death may be exercised by the legal representative or
            legatee of the optionee for a period of one year from the date of
            death or until the expiration of the stated term of the Option, if
            earlier.

                  (D) Options granted under this Section 5(c) may be exercised
            only by written notice to the Company specifying the number of
            shares to be purchased. Payment of the full purchase price of the
            shares to be purchased may be made by one or more of the methods
            specified in Section 5(a)(iv). An optionee shall have the rights of
            a shareholder only as to shares acquired upon the exercise of a
            Stock Option and not as to unexercised Stock Options.

SECTION 6.  STOCK APPRECIATION RIGHTS; DISCRETIONARY PAYMENTS.

      (a) Nature of Stock Appreciation Right. A Stock Appreciation Right is an
Award entitling the recipient to receive an amount in cash or shares of Stock
(or in a form of payment permitted under Section 6(e) below) or a combination
thereof having a value equal to (or if the Committee shall so determine at time
of grant, less than) the excess of the Fair Market Value of a share of Stock on
the date of exercise over the exercise price per share set by the Committee at
the time of grant (or over the option exercise price per share, if the Stock
Appreciation Right was granted in tandem with a Stock Option) multiplied by the
number of shares with respect to which the Stock Appreciation Right shall have
been exercised, with the Committee having the right to determine the form of
payment.

      (b) Grant and Exercise of Stock Appreciation Rights. Stock Appreciation
Rights may be granted to any employees of the Company or any Subsidiary by the
Committee in tandem with, or independently of, any Stock Option granted pursuant
to Section 5(a) of the Plan. In the case of a Stock Appreciation Right granted
in tandem with a Non-Qualified Stock Option, such Right may be granted either at
or after the time of the grant of such Option. In

                                      10
<PAGE>   11
the case of a Stock Appreciation Right granted in tandem with an Incentive Stock
Option, such Right may be granted only at the time of the grant of the Option.

      A Stock Appreciation Right or applicable portion thereof granted in tandem
with a Stock Option shall terminate and no longer be exercisable upon the
termination or exercise of the related Stock Option, except that, at the
Committee's discretion, a Stock Appreciation Right granted with respect to less
than the full number of shares covered by a related Stock Option shall only so
terminate if and to the extent that the number of shares covered by the exercise
or termination of the related Stock Option exceeds the number of shares not
covered by such Stock Appreciation Right.

      (c) Terms and Conditions of Stock Appreciation Rights. Stock Appreciation
Rights shall be subject to such terms and conditions as shall be determined from
time to time by the Committee, subject to the following:

            (i) Stock Appreciation Rights granted in tandem with Stock Options
      shall be exercisable at such time or times and to the extent that the
      related Stock Options shall be exercisable.

            (ii) Upon exercise of a Stock Appreciation Right, the applicable
      portion of any related Stock Option shall be surrendered.

            (iii) Stock Appreciation Rights granted in tandem with a Stock
      Option shall be transferable only when and to the extent that the
      underlying Stock Option would be transferable. Stock Appreciation Rights
      not granted in tandem with a Stock Option shall not be transferable
      otherwise than by will or the laws of descent or distribution. All Stock
      Appreciation Rights shall be exercisable during the participant's lifetime
      only by the participant or the participant's legal representative.

      (d) Settlement in the Form of Restricted Shares. Shares of Stock issued
upon exercise of a Stock Appreciation Right shall be free of all restrictions
under this Plan, except as otherwise provided in this Plan.

SECTION 7.  RESTRICTED STOCK AWARDS.

      (a) Nature of Restricted Stock Award. The Committee may grant Restricted
Stock Awards to any employees of the Company or any Subsidiary. In no event
shall the number of shares of Stock issued pursuant to the grant of Restricted
Stock Awards or the award of Unrestricted Stock for consideration less than Fair
Market Value at the time of the award exceed in the aggregate 10% of the maximum
number of shares of Stock reserved and available for issuance under this Plan,
as such number may be adjusted in accordance with Section 3 hereof. A Restricted
Stock Award is an Award entitling the recipient to acquire, at no cost or for a
purchase price determined by the Committee, shares of Stock subject to such
restrictions

                                      11
<PAGE>   12
and conditions as the Committee may determine at the time of grant ("Restricted
Stock"). Conditions may be based on continuing employment and/or achievement of
pre-established performance goals and objectives. A Restricted Stock Award may
be granted to an employee by the Committee in lieu of any compensation otherwise
due to such employee.

      (b) Award Agreement. A participant who is granted a Restricted Stock Award
shall have no rights with respect to such Award unless the participant shall
have accepted the Award within 60 days (or such shorter date as the Committee
may specify) following the award date by making payment to the Company by
certified or bank check or other instrument or form of payment acceptable to the
Committee in an amount equal to the specified purchase price, if any, of the
shares covered by the Award and by executing and delivering to the Company a
Restricted Stock Award Agreement in such form as the Committee shall determine.

      (c) Rights as a Shareholder. Upon complying with Section 7(b) above, a
participant shall have all the rights of a shareholder with respect to the
Restricted Stock including voting and dividend rights, subject to
non-transferability restrictions and Company repurchase or forfeiture rights
described in this Section 7 and subject to such other conditions contained in
the Award Agreement. Unless the Committee shall otherwise determine,
certificates evidencing shares of Restricted Stock shall remain in the
possession of the Company until such shares are vested as provided in Section
7(e) below.

      (d) Restrictions. Shares of Restricted Stock may not be sold, assigned,
transferred, pledged or otherwise encumbered or disposed of except as
specifically provided herein. In the event of termination of employment of the
participant by the Company and its Subsidiaries for any reason (including death,
Disability, Normal Retirement and for Cause), the Company shall have the right,
at the discretion of the Committee, to repurchase shares of Restricted Stock
with respect to which conditions have not lapsed at their purchase price, or to
require forfeiture of such shares to the Company if acquired at no cost, from
the participant or the participant's legal representative. The Company must
exercise such right of repurchase or forfeiture not later than the 90th day
following such termination of employment (unless otherwise specified in the
Award Agreement).

      (e) Vesting of Restricted Stock. The Committee at the time of grant shall
specify the date or dates and/or the attainment of performance goals, objectives
and other conditions on which the non-transferability of the Restricted Stock
and the Company's right of repurchase or forfeiture shall lapse. Subsequent to
such date or dates and/or the attainment of such pre-established goals,
objectives and other conditions, the shares on which all restrictions have
lapsed shall no longer be Restricted Stock and shall be deemed "vested." The
Committee at any time may accelerate such date or dates and otherwise waive or,
subject to Section 12, amend any conditions of the Award.


                                      12
<PAGE>   13
      (f) Waiver, Deferral and Reinvestment of Dividends. The Restricted Stock
Award Agreement may require or permit the immediate payment, waiver, deferral or
investment of dividends paid on the Restricted Stock.

SECTION 8.  UNRESTRICTED STOCK AWARDS.

      (a) Grant or Sale of Unrestricted Stock. The Committee may, in its sole
discretion, grant (or sell at a purchase price determined by the Committee) to
any employees of the Company or any Subsidiary shares of Stock free of any
restrictions under the Plan ("Unrestricted Stock"). The number of shares of
Stock issued pursuant to all awards of Unrestricted Stock shall be limited as
described in Section 7(a) hereof. Shares of Unrestricted Stock may be granted or
sold as described in the preceding sentence in respect of past services or other
valid consideration, or in lieu of any cash compensation due or payable to such
employee.

      (b) Elections to Receive Unrestricted Stock In Lieu of Compensation. Upon
the request of an employee and with the consent of the Committee, each employee
may, pursuant to an irrevocable written election delivered to the Company no
later than the date or dates specified by the Committee, receive a portion of
the cash compensation otherwise due to him in Unrestricted Stock (valued at Fair
Market Value on the date or dates the cash compensation would otherwise be
paid). Such Unrestricted Stock may be paid to the employee at the same time as
the cash compensation would otherwise be paid, or at a later time, as specified
by the employee in the written election.

      (c) Elections to Receive Unrestricted Stock in Lieu of Directors' Fees.
Each Non-Employee Director may, pursuant to an irrevocable written election
delivered to the Company no later than the date or dates specified by the
Committee, receive all or a portion of such fees in Unrestricted Stock (valued
at Fair Market Value on the date or dates the directors' fees would otherwise be
paid). Such Unrestricted Stock may be paid to the Non-Employee Director at the
same time the directors' fees would otherwise have been paid, or at a later
time, as specified by the Non-Employee Director in the written election.

      (d) Restrictions on Transfers. The right to receive Unrestricted Stock may
not be sold, assigned, transferred, pledged or otherwise encumbered, other than
by will or the laws of descent and distribution.

SECTION 9.  PERFORMANCE SHARE AWARDS.

      (a) Nature of Performance Shares. A Performance Share Award is an award
entitling the recipient to acquire shares of Stock upon the attainment of
specified performance goals. The Committee may make Performance Share Awards
independently of or in connection with the granting of any other Award under the
Plan. Performance Share Awards may be granted under the Plan to any employees of
the Company or any Subsidiary, including

                                      13
<PAGE>   14
those who qualify for awards under other performance plans of the Company. The
Committee in its sole discretion shall determine whether and to whom Performance
Share Awards shall be made, the performance goals applicable under each such
Award, the periods during which performance is to be measured, and all other
limitations and conditions applicable to the awarded Performance Shares;
provided, however, that the Committee may rely on the performance goals and
other standards applicable to other performance based plans of the Company in
setting the standards for Performance Share Awards under the Plan.

      (b) Restrictions on Transfer. Performance Share Awards and all rights with
respect to such Awards may not be sold, assigned, transferred, pledged or
otherwise encumbered.

      (c) Rights as a Shareholder. A participant receiving a Performance Share
Award shall have the rights of a shareholder only as to shares actually received
by the participant under this Plan and not with respect to shares subject to the
Award but not actually received by the participant. A participant shall be
entitled to receive a stock certificate evidencing the acquisition of shares of
Stock under a Performance Share Award only upon satisfaction of all conditions
specified in the written instrument evidencing the Performance Share Award (or
in the performance plan adopted by the Committee).

      (d) Termination. Except as may otherwise be provided by the Committee at
any time, a participant's rights in all Performance Share Awards shall
automatically terminate upon the participant's termination of employment by the
Company and its Subsidiaries for any reason (including death, Disability, Normal
Retirement, termination without Cause and termination for Cause).

      (e) Acceleration, Waiver, Etc. At any time prior to the participant's
termination of employment by the Company and its Subsidiaries, the Committee may
in its sole discretion accelerate, waive or, subject to Section 12, amend any or
all of the goals, restrictions or conditions imposed under any Performance Share
Award.

SECTION 10.  TAX WITHHOLDING.

      (a) Payment by Participant. Each participant shall, no later than the date
as of which the value of an Award or of any Stock or other amounts received
thereunder first becomes includable in the gross income of the participant for
Federal income tax purposes, pay to the Company, or make arrangements
satisfactory to the Committee regarding payment of, all Federal, state, or local
taxes of any kind required by law to be withheld with respect to such income.
The Company and its Subsidiaries shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
participant.

      (b) Payment in Shares. Subject to the approval of the Committee, a
participant may elect to have such tax withholding obligation satisfied, in
whole or in part, by (i) authorizing the Company to withhold from shares of
Stock to be issued pursuant to any Award a number of

                                      14
<PAGE>   15
shares with an aggregate Fair Market Value (as of the date the withholding is
effected) that would satisfy the withholding amount due, or (ii) transferring to
the Company shares of Stock owned by the participant with an aggregate Fair
Market Value (as of the date the withholding is effected) that would satisfy the
withholding amount due.

SECTION 11.  TRANSFER, LEAVE OF ABSENCE, ETC.

      For purposes of the Plan, the following events shall not be deemed a
termination of employment:

      (a) a transfer to the employment of the Company from a Subsidiary or from
the Company to a Subsidiary, or from one Subsidiary to another; or

      (b) an approved leave of absence for military service or sickness, or for
any other purpose approved by the Company, if the employee's right to
re-employment is guaranteed either by a statute or by contract or under the
policy pursuant to which the leave of absence was granted or if the Committee
otherwise so provides in writing.

SECTION 12.  AMENDMENTS AND TERMINATION.

      The Board may at any time amend or discontinue the Plan and the Committee
may at any time amend or cancel any outstanding Award (or provide substitute
Awards at the same or reduced exercise or purchase price or with no exercise or
purchase price, but such price, if any, must satisfy the requirements which
would apply to the substitute or amended Award if it were then initially granted
under this Plan) for the purpose of satisfying changes in law or for any other
lawful purpose, but no such action shall adversely affect rights under any
outstanding Award without the holder's consent.

SECTION 13.  STATUS OF PLAN.

      With respect to the portion of any Award which has not been exercised and
any payments in cash, stock or other consideration not received by a
participant, a participant shall have no rights greater than those of a general
creditor of the Company unless the Committee shall otherwise expressly determine
in connection with any Award or Awards. In its sole discretion, the Committee
may authorize the creation of trusts or other arrangements to meet the Company's
obligations to deliver Stock or make payments with respect to Awards hereunder;
provided that the existence of such trusts or other arrangements is consistent
with the provision of the foregoing sentence.


                                      15
<PAGE>   16
SECTION 14.  CHANGE OF CONTROL PROVISIONS.

      Upon the occurrence of a Change of Control as defined in this Section 14:

      (a) Each Stock Option, Stock Appreciation Right and Performance Share
Award shall automatically become fully exercisable unless the Committee shall
otherwise expressly provide at the time of grant.

      (b) Restrictions and conditions on Awards of Restricted Stock shall
automatically be deemed waived, and the recipients of such Awards shall become
entitled to receipt of the Stock subject to such Awards.

      (c) To the extent Section 14(a) hereof is not applicable to any Stock
Options, Stock Appreciation Rights or Performance Share Awards, the Committee
may at any time prior to or after a Change of Control accelerate the
exercisability of any Stock Options, Stock Appreciation Rights and Performance
Share Awards to the extent it shall in its sole discretion determine.

      (d) "Change of Control" shall mean the occurrence of any one of the
following events:

            (i) any "person" (as such term is used in Sections 13(d) and
      14(d)(2) of the Act) becomes a "beneficial owner" (as such term is defined
      in Rule 13d-3 promulgated under the Act) (other than the Company, any
      trustee or other fiduciary holding securities under any employee benefit
      plan of the Company, or any corporation owned, directly or indirectly, by
      the stockholders of the Company in substantially the same proportions as
      their ownership of stock of the Company), directly or indirectly, of
      securities of the Company representing 50% or more of the combined voting
      power of the Company's then outstanding securities;

            (ii) persons who, as of the date hereof, constitute the Company's
      Board (the "Incumbent Board") cease for any reason, including without
      limitation as a result of a tender offer, proxy contest, merger or similar
      transaction, to constitute at least a majority of the Board; provided that
      any person becoming a director of the Company subsequent to the date
      hereof whose nomination was approved by at least a majority of the
      directors then comprising the Incumbent Board shall, for purposes of this
      Plan, be considered a member of the Incumbent Board;

            (iii) the stockholders of the Company approve a merger or
      consolidation of the Company with any other corporation or other entity,
      other than (A) a merger or consolidation which would result in the voting
      securities of the Company outstanding immediately prior thereto continuing
      to represent (either by remaining outstanding or by being converted into
      voting securities of the surviving entity) more than 80% of the

                                      16
<PAGE>   17
      combined voting power of the voting securities of the Company or such
      surviving entity outstanding immediately after such merger or
      consolidation or (B) a merger or consolidation effected to implement a
      recapitalization of the Company (or similar transaction) in which no
      "person" (as hereinabove defined) acquires more than 50% of the combined
      voting power of the Company's then outstanding securities; or

            (iv) the stockholders of the Company approve a plan of complete
      liquidation of the Company or an agreement for the sale or disposition by
      the Company of all or substantially all of the Company's assets.

SECTION 15.  GENERAL PROVISIONS.

      (a) No Distribution; Compliance with Legal Requirements. The Committee may
require each person acquiring shares pursuant to an Award to represent to and
agree with the Company in writing that such person is acquiring the shares
without a view to distribution thereof.

      No shares of Stock shall be issued pursuant to an Award until all
applicable securities laws and other legal and stock exchange requirements have
been satisfied. The Committee may require the placing of such stop-orders and
restrictive legends on certificates for Stock and Awards as it deems
appropriate.

      (b) Delivery of Stock Certificates. Delivery of Stock certificates to
participants under this Plan shall be deemed effected for all purposes when the
Company or a stock transfer agent of the Company shall have delivered such
certificates in the United States mail, addressed to the participant, at the
participant's last known address on file with the Company.

      (c) Other Compensation Arrangements; No Employment Rights. Nothing
contained in this Plan shall prevent the Board from adopting other or additional
compensation arrangements, subject to stockholder approval if such approval is
required; and such arrangements may be either generally applicable or applicable
only in specific cases. Neither the adoption of this Plan nor the grant of any
Award to any employer shall confer upon any employee any right to continued
employment with the Company or any Subsidiary.

SECTION 16.  EFFECTIVE DATE OF PLAN.

      This Plan shall become effective upon approval by the holders of a
majority of the shares of capital stock of the Company present or represented
and entitled to vote at a meeting of stockholders. Subject to such approval by
the stockholders, and to the requirement that no Stock may be issued hereunder
prior to such approval, Stock Options and other Awards may be granted hereunder
on and after adoption of this Plan by the Board.

                              --------------------

                    EMPLOYEES' STOCK OWNERSHIP PLAN AND TRUST
                    -----------------------------------------

A.   The Trust Agreement dated April 16, 1986 by and between MASSBANK FOR 
SAVINGS, a Massachusetts savings bank having its principal place of business in
Reading, Massachusetts (the "Company"), and State Street Bank and Trust Company,
as previously amended, is hereby amended as follows:

     1.   Effective November 1, 1989, Section 2.09 is hereby amended by adding 
the following to the end thereof:

     "In determining the Compensation of a Member for purposes of this
     compensation limitation, the rules of Section 414(q)(6) of the Code shall
     apply, except that in applying such rules, the term "family" shall include
     only the spouse of the Member and any lineal descendants of the Member that
     have not attained age 19 before the close of the Plan Year. If, as a result
     of the application of such rules the adjusted limitation is exceeded, then
     the limitation shall be pro rated among the affected individuals in
     proportion to each such individual's Compensation as determined under this
     Section prior to the application of this limitation."

     2.   Effective November 1, 1994, Section 2.09 is hereby further amended by
adding the following to the end thereof:

     "In addition to other applicable limitations set forth in the Plan, and
     notwithstanding any other provision of the Plan to the contrary, for Plan
     Years beginning on or after January 1, 1994, the annual Compensation of
     each Employee taken into account under the Plan shall not exceed the OBRA
     '93 annual compensation limit. The OBRA '93 annual compensation limit is
     $150,000, as adjusted by the Commissioner for increases in the cost of
     living in accordance with Section 401(a)(17)(B) of the Code. The
     cost-of-living adjustment in effect for a calendar year applies to any
     period, not exceeding 12 months, beginning in such calendar year over which
     compensation is determined (determination period). If a determination
     period consists of fewer than 12 months, the OBRA '93 annual compensation
     limit will be multiplied by

<PAGE>   2

     a fraction, the numerator of which is the number of months in the
     determination period, and the denominator of which is 12.

     For Plan Years beginning on or after January 1, 1994, any reference in this
     Plan to the limitation under Section 401(a)(17) of the Code shall mean the
     OBRA '93 annual compensation limit set forth in this provision."

     3.   Effective January 1, 1993, the following Article XV is added 
immediately following the end of Article XIV:

                                   "ARTICLE XV

                                DIRECT ROLLOVERS

          15.01 APPLICATION OF THIS ARTICLE. This Article applies to
     distributions made on or after January 1, 1993. Notwithstanding any
     provision of the Plan to the contrary that would otherwise limit a
     distributee's election under this Article, a distributee may elect, at the
     time and in the manner prescribed by the Committee, to have any portion of
     an eligible rollover distribution paid directly to an eligible retirement
     plan specified by the distributee in a direct rollover.

          15.02 WAIVER OF 30-DAY NOTICE. Notwithstanding the foregoing, if a
     distribution is one to which Sections 401(a)(11) and 417 of the Code do not
     apply, such distributions may commence less than 30 days after the notice
     required under Section 1.411(a)-11(c) of the Income Tax Regulations is
     given, provided that:

               (a) the Committee clearly informs the Member that the Member has
               a right to a period of at least 30 days after receiving the
               notice to consider the decision of whether or not to elect a
               distribution (and, if applicable, a particular distribution
               option), and

               (b) the Member, after receiving the notice, affirmatively elects
               a distribution.

          15.03 DEFINITIONS. Whenever used in this Article, the following words
     shall have the following meanings:

               (a) ELIGIBLE ROLLOVER DISTRIBUTION: An eligible rollover
               distribution is any distribution of all or any portion of the
               balance to the credit of the distributee, except that an eligible
               rollover distribution does not include: any distribution that is
               one of a series of substantially equal



                                       2
<PAGE>   3

               periodic payments (not less frequently than annually) made for
               the life (or life expectancy) of the distributee or the joint
               lives (or joint life expectancies) of the distributee and the
               distributee's designated beneficiary, or for a specified period
               of ten years or more; any distribution to the extent such
               distribution is required under Section 401(a)(9) of the Code; and
               the portion of any distribution that is not includible in gross
               income (determined without regard to the exclusion for net
               unrealized appreciation with respect to employer securities).

               (b) ELIGIBLE RETIREMENT PLAN: An eligible retirement plan is an
               individual retirement account described in Section 408(a) of the
               Code, an individual retirement annuity described in section
               408(b) of the Code, an annuity plan described in section 403(a)
               of the Code, or a qualified trust described in Section 401(a) of
               the Code, that accepts the distributee's eligible rollover
               distribution. However, in the case of an eligible rollover
               distribution to the surviving spouse, an eligible retirement plan
               is an individual retirement account or individual retirement
               annuity.

               (c) DISTRIBUTEE: A distributee includes an employee or former
               employee. In addition, the employee's or former employee's
               surviving spouse and the employee's or former employee's spouse
               or former spouse who is the alternate payee under a qualified
               domestic relations order, as defined in Section 414(p) of the
               Code, are distributees with regard to the interest of the spouse
               or former spouse.

               (d) DIRECT ROLLOVER: A direct rollover is a payment by the Plan
               to the eligible retirement plan specified by the distributee."

B.   The Trust Agreement is in all other respects hereby confirmed.

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

GENERAL

The following discussion should be read in conjunction with the consolidated
financial statements and related notes included in this report. Certain amounts
reported for prior years have been reclassified to conform to the 1997
presentation. The discussion contains certain forward-looking statements
regarding the future performance of the Company. All forward-looking information
is inherently uncertain and actual results may differ substantially from the
assumptions, estimates, or expectations reflected or contained in the
forward-looking information.

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

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


RECENT DEVELOPMENTS

ACQUISITION OF GLENDALE CO-OPERATIVE BANK

On February 26, 1997 the Company's wholly-owned subsidiary, MASSBANK, executed
an agreement with the Glendale Cooperative Bank ("Glendale") pursuant to which
MASSBANK would acquire all of the outstanding shares of Glendale at a price of
$28.00 per share. The transaction was valued at $7.38 million. Glendale operated
a single banking office in the city of Everett with total assets of $35.6
million. On July 21, 1997 MASSBANK consummated the acquisition. The transaction
was accounted for as a purchase.


FINANCIAL CONDITION

Total assets at December 31, 1997 were $925.4 million, an increase of 4.2%, or
$37.2 million from $888.2 million a year ago. The increase is largely
attributable to the securities, loans and other assets acquired in the Glendale
purchase. Glendale on the closing date had total assets of $35.6 million.
Short-term investments in 1997 decreased $24.6 million. This was fully offset by
increases in term federal funds sold and trading securities. Goodwill at
year-end 1997 totaled $1.5 million reflecting the premium paid in connection
with the Glendale purchase.

        The Bank's total loan portfolio increased $22.6 million to $272.3
million at December 31, 1997 reflecting approximately $14.0 million in loans
acquired in connection with the Glendale purchase and modest internal growth.
Internal net loan growth in 1997 was approximately 3.4%, or $8.6 million,
compared with a slight net increase in loans of $0.5 million, in 1996. Loan
originations totaled $58.6 million in 1997, up 14.0%, or $7.2 million compared
to $51.4 million in 1996. The level of principal amortization and payoffs in the
Bank's portfolio continues to be high, making it difficult to grow the
portfolio. This is due in part to the shorter term mortgages that the Bank
originates and the prevailing low interest rates which encourage borrowers to
prepay higher rate mortgages.

        Total investments consisting of investment securities and other short
term investments, including term federal funds sold and interest-bearing bank
deposits, increased from $622.6 million at December 31, 1996 to $635.7 million
at December 31, 1997. These investments are principally in federal funds sold,
short-term U.S. Treasury notes and government agency fifteen year
mortgage-backed securities. Essentially all of the Bank's investment securities
are classified as either available for sale or trading securities. Investment
securities available for sale and trading securities provide liquidity,
facilitate interest rate risk management and enhance the Bank's ability to
respond to customers' needs should loan demand increase and/or deposits decline.

        Adding to the increase in total investments was a change in net
unrealized gains on securities available for sale from $6.9 million at December
31, 1996 to $15.5 million at December 31, 1997, an $8.6 million increase in
market value. The increase in market value of the investment securities
portfolio is directly related to the upward movement in both bond and stock
prices in 1997.

        The change in the market value of the Bank's securities available for
sale also had the effect of increasing stockholders' equity by $5.1 million
since year-end 1996. The net unrealized gains on securities available for sale,
net of tax effect reported as part of stockholders' equity totaled $9.1 million
at year-end 1997, up from $4.0 million at December 31, 1996. Total stockholders'
equity was $103.8 million at December 31, 1997, up $11.5 million from $92.3
million at December 31, 1996. Also contributing to the increase in stockholders'
equity was the Company's record net income of $10.2 million in 1997 and the
issuance of common stock under the Company's stock option plan. These were
partially offset by the payment of $3.1 million in dividends to stockholders and
the cost of the additional shares of treasury stock repurchased during the year
of $1.7 million.



                                                                              25
<PAGE>   3
FINANCIAL CONDITION (continued)

Record earnings in 1997 and a strong capital position have permitted the Company
to continue to reward its shareholders through the payment of higher quarterly
cash dividends. The Company's Board of Directors has increased the quarterly
cash dividend paid to shareholders twice during 1997. Annual cash dividends per
share paid to shareholders during 1997 increased 28% over the prior year. The
Company's book value per share at December 31, 1997 was $29.06, up $3.31 or
12.9% from the prior year.

        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 deposits increased by $21.5 million
or 2.7% during the twelve months ended December 31, 1997, from $788.4 million at
year end 1996 to $809.9 million at the end of 1997. The increase is attributable
to the $29.8 million in deposits acquired in connection with the Glendale
purchase. Also, in 1997, the Bank experienced some modest deposit outflow due to
the strong performance of the stock market and mutual funds which were both
fierce competitors for the savers' dollars.


ASSET QUALITY

Net loans represented 29.2% of total assets at December 31, 1997 compared to
27.9% of total assets at December 31, 1996. The Bank's investment securities and
other short-term investments, representing 68.7% of total assets at December 31,
1997, consisted primarily of U.S. Treasury notes, government agency
mortgage-backed securities and federal funds sold. At December 31, 1997, the
Bank's loan portfolio consisted of residential mortgages of $244.9 million,
commercial mortgages of $3.9 million and consumer loans of $23.5 million.
Non-performing assets were $1.8 million at December 31, 1997, representing 0.19%
of total assets. This compares to $2.1 million, or 0.24% of total assets, at
December 31, 1996. At year end 1997, the Bank's allowance for loan losses was
approximately $2.3 million, representing 131.8% of non-performing loans and
0.86% of total loans. The Bank believes that its allowance for loan losses is
adequate to cover the risks inherent in the loan portfolio under current
conditions. Also, as of year-end 1997, the Company had no real estate acquired
through foreclosure on its balance sheet.


RESULTS OF OPERATIONS

COMPARISON OF THE YEARS 1997 AND 1996

MASSBANK Corp. recorded record net income for the year ended December 31, 1997
of $10.2 million or $2.88 in basic earnings per share compared to $9.4 million
or $2.65 in basic earnings per share for the year ended December 31, 1996. On a
diluted basis, the Company earned $2.77 per share in 1997, up 7.4% or $0.19 per
share from the $2.58 in diluted earnings per share reported in 1996.

        In 1997, MASSBANK achieved record breaking results in net income,
earnings per share and return on average realized equity, and increased its
return on average assets. Return on average realized equity and return on
average assets improved to 11.11% and 1.12% in 1997 from 11.01% and 1.08% in
1996, respectively. The Company's favorable financial performance in 1997 can be
attributed to an improvement in net interest income and higher securities gains,
partially offset by an increase in non-interest expenses and provision for loan
losses. Also, in 1997, the Bank received a non-recurring tax benefit of
approximately $260,000 from a donation of appreciated securities made to endow
the MASSBANK Charitable Foundation, a tax exempt private foundation established
for the purpose of making grants in future years to benefit the Bank's local
communities.


NET INTEREST INCOME

The Company's net interest income on a fully taxable equivalent ("FTE") basis
was $26.2 million in 1997, an increase of $1.0 million over the prior year. This
year's improvement in net interest income reflects the positive effect of
earning asset growth exceeding the negative effect of a slightly lower net
interest margin. The Company's average earning assets increased $42.3 million or
5% to $894.6 million in 1997, up from $852.3 million in 1996. The Company's net
interest margin was 2.93% in 1997, slightly below its 1996 net interest margin
of 2.96%.

        The tables on pages 34 and 35 set forth, among other things, the extent
to which changes in interest rates and changes in the average balances of
interest-earning assets and interest-bearing liabilities have affected interest
income and expense during the years indicated. For each category of
interest-earning assets and interest-bearing liabilities, information is
provided on changes due to (1) changes in volume and (2) changes in interest
rates.



26
<PAGE>   4
INTEREST AND DIVIDEND INCOME

Interest and dividend income on a fully taxable equivalent basis was $60.9
million for the year ended December 31, 1997, compared to $58.3 million for the
year ended December 31, 1996. The average total earning assets of the Company
increased to $894.6 million in 1997, up $42.3 million from $852.3 million in
1996. As reflected in the table on page 35, the combination of yield declines in
loans and investment securities, partially offset by yield increases in federal
funds sold and short-term investments, resulted in an overall decline in yield
on total average earning assets of 3 basis points. The weighted average yield on
earning assets for the year ended December 31, 1997 was 6.81% compared to 6.84%
in the prior year.

      As exhibited in the rate/volume analysis table on page 34, the total
effect of lower earning asset rates on interest income in 1997 was a $270
thousand decline from 1996. Conversely, the total effect of higher average
earning assets on interest income in 1997 was a $2.9 million increase over 1996,
resulting in a net increase in total interest and dividend income of $2.6
million over 1996.


INTEREST EXPENSE

Total interest expense increased 4.9% to $34.7 million for the year ended
December 31, 1997 from $33.1 million for the year ended December 31, 1996. This
increase is due to an increase in the Company's average deposits, from $774.4
million in 1996 to $807.3 million in 1997, coupled with an increase in the
Company's average cost of funds from 4.27% in 1996 to 4.30% in 1997. The
increase in the Company's average total deposits in 1997 is attributable to the
deposits acquired in connection with the Glendale purchase and internal growth.

      As reflected in the table on page 35, the migration from lower cost
savings deposits to higher cost CDs, combined with the growth in CDs in 1997,
contributed significantly to the Company's increased cost of funds in 1997.

      As exhibited in the rate/volume analysis table on page 34, the effect on
total interest expense from changes in interest bearing deposit rates from a
year ago was a $219 thousand decrease from 1996. Conversely, the total effect of
higher average deposits on interest expense in 1997 was a $1.8 million increase
over 1996, resulting in a net increase in total interest expense of $1.6 million
over 1996.


PROVISION FOR LOAN LOSSES

The provision for loan losses in 1997 was $260 thousand compared to $160
thousand in 1996. In determining the amount to provide for loan losses, the key
factor is the adequacy of the allowance for loan losses. In making its decision,
management considers a number of factors, including the risk characteristics of
the portfolio, underlying collateral, current and anticipated economic
conditions, and trends in loan delinquencies and charge-offs. At December 31,
1997, the allowance for loan losses was $2.3 million representing 131.8% of
non-performing loans. The Bank's non-performing loans totaled $1.8 million at
December 31, 1997 compared to $1.6 million a year earlier. Net charge-offs
totaled $268 thousand in 1997 compared to $452 thousand in 1996. Management
believes that the allowance for loan losses is adequate to cover the risks
inherent in the loan portfolio under current conditions.


NON-INTEREST INCOME

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

      Non-interest income increased to $3.8 million for the year ended December
31, 1997, from $2.7 million for the year ended December 31, 1996. This
improvement is due to an increase in securities gains in 1997.

      Net gains on securities totaled $1.9 million in 1997 compared to $868
thousand in 1996. Included in the $1.9 million in securities gains is $620
thousand in market appreciation on securities contributed to the MASSBANK
Charitable Foundation. All other non-interest income combined increased $62
thousand to $1.9 million from $1.8 million in the prior year.


NON-INTEREST EXPENSE

Non-interest expenses (i.e., operating expenses) increased by $1.3 million in
1997, from $12.1 million a year ago. This increase is due largely to an increase
in those expenses which are tied to the Company's stock performance and
non-recurring expenses incurred in 1997 which are summarized below:

      Salaries and employee benefits increased by $528 thousand or 7.3%, to $7.7
million in 1997, from $7.2 million in 1996. The increase reflects a $247
thousand increase in Employee Stock Ownership Plan ("ESOP") and Deferred
Compensation Plan expenses which are tied to MASSBANK Corp.'s stock performance.
The price of MASSBANK Corp. stock increased by $19.03 or 66.6% in 1997, from
$28.59 at December 31, 1996 to $47.62 at December 31, 1997. In addition,
salaries increased by $289 thousand due primarily to normal salary increases
granted to employees. These increases were partially offset by a decrease in the
costs of employee retirement benefits of $86 thousand. The expense for all other
employee benefits combined increased $78 thousand over 1996.


                                                                              27
<PAGE>   5
NON-INTEREST EXPENSE (continued)

      Occupancy and equipment expense increased by $119 thousand to $2.1 million
in 1997. This is due largely to an increase in depreciation expense resulting
from building and leasehold improvements and the computer equipment that the
bank purchased in conjunction with its computer conversion in July, 1997. The
Bank made this change to its computer systems to enhance its technological
capabilities in order to better service its customers and continue to provide
increased efficiencies throughout the bank.

      Data processing expenses were reduced by $170 thousand to $438 thousand in
1997, from $608 the previous year. This decrease reflects $150 thousand in total
credits that the bank negotiated as part of its initial contract with a new data
center which it converted to in July, 1997. The temporary reduction in data
processing expense was used to defray nonrecurring expenses which the bank
incurred in converting to the new data center.

      Professional services expenses increased by $67 thousand to $407 thousand
in 1997, from $340 thousand in 1996. This increase was due mostly to an increase
of $40 thousand in legal fees.

      The non-recurring merger and acquisition related expenses incurred in
connection with the acquisition of the Glendale Co-operative Bank totaled $156
thousand in 1997.

      Advertising and marketing expenses were reduced by $33 thousand to $187
thousand in 1997, from $220 thousand in 1996.

      The amortization of intangibles expense was $251 thousand in 1997, up from
$230 thousand in 1996. This increase is due to the Glendale acquisition.

      Deposit insurance expense in 1997 increased $103 thousand over 1996 due to
increases in the FDIC deposit insurance and Depositors Insurance Fund ("DIF")
assessments. The DIF insures customer deposits in excess of the FDIC insurance
limits. The increased assessments are attributable to higher deposit volume and
the FDIC's Financing Corporation (FICO) debt service assessment which became
applicable to all insured institutions as of January 1, 1997, in accordance with
the Deposit Insurance Act of 1996.

      The bank's contributions expense increased to $664 thousand in 1997, from
$60 thousand in the prior year. In the second quarter 1997, the bank 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. The bank contributed appreciated equity securities
valued at $622 thousand. This expense will benefit the bank by reducing its
contributions expense in future years, since many of the contributions
previously made by the bank will now be made by the Foundation.

      Other expenses were reduced by $94 thousand to $1.4 million in 1997, from
$1.5 million in 1996. This decrease is essentially due to a reduction in real
estate acquired through foreclosure expenses.


INCOME TAX EXPENSE

The Company recorded a tax expense of $6.0 million in 1997 and 1996. The
effective income tax rate for the year ended December 31, 1997 was 37.1%, a
decrease from 38.9% in 1996. In 1997, the Bank received a non-recurring tax
benefit of approximately $260,000 as a result of having donated appreciated

RESULTS OF OPERATIONS

Comparison of the Years 1996 and 1995
Massbank Corp. reported record net income for the year ended December 31, 1996
of $9.4 million or $2.65 in basic earnings per share compared to $8.8 million or
$2.43 in basic earnings per share for the year ended December 31, 1995. On a
diluted basis, the Company earned $2.58 per share in 1996, up 10.3% or $0.24 per
share from the $2.34 in diluted earnings per share reported in 1995.

      This is the fourth consecutive year that the Company has achieved record
breaking results in net income, earnings per share and return on average
realized equity, and the sixth consecutive year of increase in the Company's
return on average assets. Return on average realized equity and return on
average assets improved to 11.01% and 1.08% in 1996 from 10.81% and 1.04% in
1995, respectively. The Company's improved financial performance in 1996 can be
attributed to several factors. Non-interest expenses were down again in 1996 due
to incremental improvements throughout the Bank and another substantial drop in
deposit insurance expense; securities gains increased significantly over 1995;
and the provision for loan losses decreased slightly. Offsetting these factors
were decreases in net interest income and other non-interest income.


NET INTEREST INCOME

Net interest income on a fully taxable equivalent ("FTE") basis totaled $25.2
million for 1996, compared to $25.8 million for 1995. The decrease of $0.6
million was due principally to a decrease in net interest margin. The impact of
the lower net interest margin in 1996 was partially offset by an increase in the
Company's average earning assets from $822.0 million in 1995 to $852.3 million
in 1996. The Company's net interest margin in 1996 was 2.96%, 19 basis points
lower than the 3.15% of the prior year.

NET INTEREST INCOME (continued)

      The tables on pages 34 and 35 set forth, among other things, the extent to
which changes in interest rates and changes in the average balances of
interest-earning assets and interest-bearing liabilities have affected interest
income and expense during the years indicated. For each category of
interest-earning assets and interest-bearing liabilities, information is
provided on changes due to (1) changes in volume and (2) changes in interest
rates.


INTEREST AND DIVIDEND INCOME

Interest and dividend income on an FTE basis was $58.3 million for the year
ended December 31, 1996, compared to $56.7 million for the year ended December
31, 1995. The weighted average yield on earning assets for the year ended
December 31, 1996 decreased to 6.84% from 6.90% for the year ended December 31,
1995. The average total earning assets of the Company increased to $852.3
million in 1996, up $30.3 million from $822.0 million in 1995.

      Interest on loans decreased $0.1 million to $19.4 million for the year
ended December 31, 1996. The decrease in interest income earned on loans was due
principally to a decrease in yield. The yield on the Bank's loans declined 23
basis points to 7.70% for the year ended December 31, 1996 compared to 7.93% for
the year ended December 31, 1995. The reduction in yield was partially offset by
an increase of $6.1 million in average loan volume. The decline in market
interest rates in the first half of 1996 compared to 1995 generated more
residential loan growth for the Bank, but at lower yields. This, along with
floating rate loans and adjustable rate mortgage loans which repriced downward,
had the greatest impact on the Bank's loan yields during 1996.
 
      Interest and dividend income (on an FTE basis) from investments consisting
of investment securities (including mortgage-backed securities), trading
securities, federal funds sold and other short-term investments increased by
$1.6 million to $38.8 million in 1996 from $37.2 million in 1995. This increase
resulted primarily from an increase of $24.2 million in average volume. Average
total investments were $600.3 million in 1996 compared to $576.1 million in
1995. The weighted average yield on investments was 6.47% in 1996 and 1995.


INTEREST EXPENSE

Total interest expense increased 7.0% to $33.1 million for the year ended
December 31, 1996 from $30.9 million for the year ended December 31, 1995. This
increase is due to an increase in the Company's average cost of funds from 4.11%
in 1995 to 4.27% in 1996, coupled with an increase of $21.9 million in the
Company's average deposits, from $752.5 million in 1995 to $774.4 million in
1996. The growth in average deposits is attributable to an increase in time
certificates of deposit (CD). The average CD volume increased by $52.3 million
to $352.4 million in 1996, from $300.1 million in 1995. Partially offsetting
this increase was a reduction of $30.4 million in the average savings, and
demand and NOW deposit volume, from $452.4 in 1995 to $422.0 million in 1996.
The migration from lower cost savings deposits to higher cost (longer term) CDs,
combined with the growth in CDs in 1996, contributed significantly to the
Company's increased cost of funds in 1996.


PROVISION FOR LOAN LOSSES

The provision for loan losses in 1996 was $160 thousand compared to $170
thousand in 1995. In determining the amount to provide for loan losses, the key
factor is the adequacy of the allowance for loan losses. In making its decision,
management considers a number of factors, including the risk characteristics of
the portfolio, underlying collateral, current and anticipated economic
conditions, and trends in loan delinquencies and charge-offs. At December 31,
1996, the allowance for loan losses was $2.2 million representing 139.7% of
non-performing loans. The Bank's non-performing loans totaled $1.6 million at
December 31, 1996 compared to $2.4 million a year earlier. Net charge-offs
totaled $452 thousand in 1996 compared to $207 thousand in 1995. Management
believes that the allowance for loan losses is adequate to cover the risks
inherent in the loan portfolio under current conditions.


NON-INTEREST INCOME

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

      Non-interest income increased to $2.7 million for the year ended December
31, 1996, from $1.9 million for the year ended December 31, 1995. This
improvement is due to a significant increase in securities gains, the results of
a strong stock market in 1996, partially offset by a slight decrease in all
other non-interest income.

      Net gains on securities totaled $868 thousand in 1996 compared to $92
thousand in 1995. All other non-interest income decreased from $1.9 million in
1995 to $1.8 million in 1996 due primarily to non-recurring income recorded in
1995. In 1995, the Company recorded interest on tax settlements which it had
received from the IRS totaling $51 thousand.


                                                                              29
<PAGE>   7
NON-INTEREST EXPENSE

Non-interest expenses (i.e., operating expenses) decreased by $1.1 million or
8.0% to $12.1 million in 1996, from $13.2 million in 1995.

      Salaries and employee benefits decreased by $45 thousand to $7.2 million
in 1996 from $7.3 million in 1995. This improvement was due to a decrease in the
costs of employee retirement benefits partially offset by a modest increase in
salaries due to normal salary increases granted to employees.

      Occupancy and equipment expense decreased by $14 thousand to approximately
$2.0 million in 1996 due mostly to a reduction in depreciation expense.

      Data processing and professional services expenses were reduced by $74
thousand to $948 thousand in 1996, from approximately $1.0 million the previous
year.

      Deposit insurance expense in 1996 took another substantial drop due to a
further reduction in Federal Deposit Insurance Corporation ("FDIC") deposit
insurance rates. FDIC deposit insurance rates were reduced to an annual minimum
of $2 thousand for 1996. As a result, total deposit insurance expense decreased
from $914 thousand in 1995 to $13 thousand in 1996. Deposit insurance expense
also includes an assessment from the Depositors Insurance Fund ("DIF") to insure
customer deposits in excess of the FDIC insurance limits.

      All other expenses essentially stayed flat in 1996.


INCOME TAX EXPENSE

The Company recorded a tax expense of $6.0 million in 1996 compared to
approximately $5.5 million in 1995. The effective income tax rate for the year
ended December 31, 1996 was 38.9%, a modest increase from 38.8% in 1995. For
further information on income taxes, see Note 12 of Notes to Consolidated
Financial Statements.


LIQUIDITY AND CAPITAL RESOURCES 


The Bank must maintain a sufficient level of cash and assets which can readily
be converted into cash in order to meet cash outflows from normal depositor
requirements and loan demands. The Bank's primary sources of funds are deposits,
loan amortization and prepayments, sales or maturities of investment securities
and income on earning assets. In addition to loan payments and maturing
investment securities, which are relatively predictable sources of funds, the
Bank maintains a high percentage of its assets invested in overnight federal
funds sold, which can be immediately converted into cash, and United States
Treasury and Government agency securities, which can be sold or pledged to raise
funds. At December 31, 1997, the Bank had $85.2 million or 9.2% of total assets
and $132.8 million or 14.4% of total assets invested, respectively, in overnight
federal funds sold and United States obligations.

      The Bank is a Federal Deposit Insurance Corporation insured institution
subject to the FDIC regulatory capital requirements. The FDIC regulations
require all FDIC insured institutions to maintain minimum levels of Tier I
capital. Highly rated banks (i.e., those with a composite rating of 1 under the
CAMEL rating system) are required to maintain a minimum leverage ratio of Tier I
capital to total average assets of at least 3.00%. An additional 100 to 200
basis points are required for all but these most highly rated institutions. The
Bank is also required to maintain a minimum level of risk-based capital. Under
the new risk-based capital standards, FDIC insured institutions must maintain a
Tier I capital to risk-weighted assets ratio of 4.00% and are generally expected
to meet a minimum total qualifying capital to risk-weighted assets ratio of
8.00%. The new risk-based capital guidelines take into consideration risk
factors, as defined by the regulators, associated with various categories of
assets, both on and off the balance sheet. Under the guidelines, capital
strength is measured in two tiers which are used in conjunction with risk
adjusted assets to determine the risk-based capital ratios. Tier II capital
components include supplemental capital components such as qualifying allowance
for loan losses and qualifying subordinated debt. Tier I capital 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 December 31, 1997, the Bank had a leverage
Tier I capital to average assets ratio of 9.85%, a Tier I capital to
risk-weighted assets ratio of 32.87% and a total capital to risk-weighted assets
ratio of 33.73%. The Company, on a consolidated basis, had ratios of leverage
Tier I capital to average assets of 10.23%, Tier I capital to risk-weighted
assets of 34.14% and total capital to risk-weighted assets of 35.01% at December
31, 1997.


YEAR 2000 ISSUES


The Company has conducted a review of its computer systems to identify the
systems that could be affected by the Year 2000 issues and is developing a
comprehensive compliance plan to address the issues. The year 2000 problem is
the result of computer programs being written using two digits rather than four,
to define the applicable year. Any of the Company's systems that have time
sensitive software may recognize a date using "00" as the year 1900 rather than
the year 2000. This could result in a


30

YEAR 2000 ISSUES (continued)

system failure or in miscalculations. While the company uses a third party data
center for the majority of its data processing, the Company has incurred and
will continue to incur expenses in connection with the testing and updating of
its computer systems to prepare for the Year 2000. At this time, these
expenditures are not expected to be material.

        Systems conversion and testing activities are currently in process. In
addition, the Company is developing contingency plans for any hardware or
software that does not function correctly on January 1, 2000.

      Management presently does not believe that the Year 2000 issues will pose
significant operational problems for the Company. However, to comply with
regulatory directives, modifications and conversions must be made by the
Company's third party data center and other banks and governmental agencies that
interface with the Company. If such entities are not compliant in a timely
manner, the Year 2000 problem could have a material adverse affect on the
Company's operations.

ASSET AND LIABILITY MANAGEMENT

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


INTEREST RATE RISK


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

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

      Financial instruments calling for future cash flows show market value
increases or decreases when rates change. Management monitors the potential
change in market value of the Company's debt securities assuming an immediate
(parallel) shift in interest rates of up to 200 basis points up or down. Results
are calculated using industry standard modeling analytics and securities data
from The Bloomberg. The Company uses the results to review the potential changes
in market value resulting from immediate rate shifts and to manage the effect of
market value changes on the Company's capital position.
 
      Reinvestment risk occurs when an asset and the liability funding the asset
do not reprice and/or mature at the same time. The difference or mismatch with
respect to repricing frequency and/or maturity is a risk to net interest income.

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

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

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

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

      GAP analysis provides a static view of the maturity and repricing
characteristics of the Company's balance sheet positions. The interest rate GAP
is prepared by scheduling all interest-earning assets and interest-bearing
liabilities according to scheduled or anticipated repricing or maturity. The GAP
analysis identifies the difference between an institution's assets and 


                                                                              31
<PAGE>   9
INTEREST RATE RISK (continued)

liabilities that will react to a change in market rates. GAP analysis theory
postulates that if the GAP is positive and rates increase, profits will increase
as more assets than liabilities react to the rate change. If the GAP is
negative, more liabilities than assets will react to a change in market rates.
If rates rise, the institution's profits will fall as more liabilities react to
market rates than assets.

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

      The Company's policy is to limit its one-year GAP position to 15 percent
of total assets. The Company has historically managed its interest rate GAP
primarily by lengthening or shortening the maturity structure of its securities
portfolio, by continually modifying the composition of its securities portfolio
and by selectively pricing and marketing its various deposit products.

      The following table summarizes the Company's GAP position at December 31,
1997. As of this date, the Company's one-year cumulative GAP position was
negative $99.4 million, or approximately 10.74% of total assets. The cumulative
GAP-asset ratio measures the direction and extent of imbalance between an
institution's assets and liabilities repricing through the end of a particular
period.

</TABLE>

(1) Securities rates presented are on a tax equivalent basis.

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


OTHER MARKET RISKS

The Company's investment securities portfolio includes equity securities with a
market value of approximately $17.5 million at December 31, 1997. The net
unrealized gains on these securities totaled $8.2 million at year-end 1997.
Movements in equity prices may effect the amount of securities gains or losses
which the Company realizes from the sale of these securities and thus may have
an impact on earnings.


                                                                              33

RATE/VOLUME ANALYSIS

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

IMPACT OF INFLATION AND CHANGING PRICES

MASSBANK Corp.'s financial statements presented herein have been prepared in
accordance with generally accepted accounting principles which require the
measurement of financial position and operating results in terms of historical
dollars, without considering changes in the relative purchasing power of money
over time, due to the fact that substantially all of the assets and liabilities
of a financial institution are monetary in nature. As a result, interest rates
have a more significant impact on a financial institution's performance than the
effects of general levels of inflation. Interest rates do not necessarily move
in the same direction or in the same magnitude as the prices of goods and
services.


RECENT ACCOUNTING PRONOUNCEMENTS

EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per
Share." This Statement supersedes APB Opinion No. 15 regarding the presentation
of earnings per share ("EPS") on the face of the income statement. SFAS No. 128
replaces the presentation of Primary EPS with a Basic EPS calculation that
excludes the dilutive effect of common stock equivalents. The Statement requires
a dual presentation of Basic and Dilutive EPS, which is computed similarly to
Fully Diluted EPS pursuant to APB Opinion No. 15 for all entities with complex
capital structures. This Statement is effective for fiscal years ending after
December 15, 1997 and requires restatement of all prior-period EPS data
presented. The adoption of this pronouncement did not have a material impact on
the Company's earnings per share presentation.


DISCLOSURE OF INFORMATION ABOUT CAPITAL STRUCTURE

In February 1997, the FASB issued SFAS No. 129, "Disclosure of Information about
Capital Structure". This Statement establishes standards for disclosing
information about an entity's capital structure. It applies to all entities and
is effective for reporting periods ending after December 15, 1997. The Company's
disclosures comply with these new requirements.


REPORTING COMPREHENSIVE INCOME

In June 1997, the FASB issued of SFAS 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.

        Statement 130 is effective for interim and annual periods beginning
after December 15, 1997. Earlier application is permitted. Comparative financial
statements provided for earlier periods are required to be reclassified to
reflect application of the provisions of the Statement. The Statement is not
expected to have a material impact on the Company's financial presentation.

DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION

In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." This Statement establishes standards for
reporting information about operating segments. An operating segment is defined
as a component of an enterprise for which separate financial information is
available and reviewed regularly by the enterprise's chief operating decision
maker in order to make decisions about resources to be allocated to the segment
and also to evaluate the segment's performance. SFAS No. 131 requires a company
to disclose certain balance sheet and income statement information by operating
segment, as well as provide a reconciliation of operating segment information to
the company's consolidated balances. This Statement is effective for reporting
periods beginning after December 15, 1997. This Statement is not expected to
have a material impact on the Company's financial presentation.

Independent Auditors' Report

[KPMG PEAT MARWICK LLP LETTERHEAD]

The Board of Directors and Stockholders
MASSBANK Corp.:

            We have audited the accompanying consolidated balance sheets of
MASSBANK Corp. and subsidiaries as of December 31, 1997 and 1996, and the
related consolidated statements of income, changes in stockholders' equity and
cash flows for each of the years in the three-year period ended December 31,
1997. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

            We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

            In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the financial position of
MASSBANK Corp. and subsidiaries at December 31, 1997 and 1996, and the results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 1997, in conformity with generally accepted accounting
principles.

   MASSBANK CORP. AND SUBSIDIARIES
   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
   Years ended December 31, 1997, 1996 and 1995

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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


   BASIS OF PRESENTATION

   The consolidated financial statements include the accounts of
   the Company and its wholly-owned subsidiaries: MASSBANK, Readibank
   Properties, Inc., Readibank Investment Corporation and Melbank Investment
   Corporation. The accounts of MASSBANK's subsidiary, Readibank Equipment
   Corportation, which was sold in October, 1997 are also included through the
   sale date. All significant intercompany balances and transactions have been
   eliminated in consolidation. The accounting and reporting policies of the
   Company conform to generally accepted accounting principles and to general
   practices within the banking industry. In preparing the consolidated
   financial statements, management is required to make estimates and
   assumptions that affect the reported amounts of assets and liabilities at the
   balance sheet date and income and expenses for the period. Material estimates
   that are particularly susceptible to change in the near term relate to the
   determination of the allowance for loan losses.

           Certain amounts in the prior years' consolidated financial statements
   were reclassified to permit comparison with the current fiscal year. The
   Company's reported per share amounts and average common and common equivalent
   shares outstanding for 1997 and prior years have been restated to reflect the
   Company's four-for-three stock split of September 15, 1997.

   INVESTMENTS IN DEBT AND EQUITY SECURITIES

   Under its investment policy, management determines the appropriate
   classification of securities at the time of purchase. Those debt
   securities that the Company has the intent and the ability to hold to
   maturity are classified as securities held to maturity and are carried at
   amortized historical cost. Those securities held for indefinite periods of
   time and not intended to be held to maturity are classified as available
   for sale. Securities held for indefinite periods of time include
   securities that management intends to use as part of its asset/liability
   management strategy and that may be sold in response to changes in
   interest rates, changes in prepayment risk, the need to increase
   regulatory capital and other similar factors. The Company records
   investment securities available for sale at aggregate market value with
   the net unrealized holding gains or losses reported, net of tax effect, as
   a separate component of stockholders' equity until realized. As of
   December 31, 1997, stockholders' equity included approximately $9.1
   million, representing the net unrealized gains on securities available for
   sale, less applicable income taxes. Investments classified as trading
   securities are stated at market value with unrealized gains and losses
   included in earnings.

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


   LOANS

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

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

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

                                                                              43

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

   ALLOWANCE FOR LOAN LOSSES

   The Company maintains an allowance for probable losses that are inherent in
   the Company's loan portfolio. The allowance for loan losses is increased by
   provisions charged to operations based on 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.


   PREMISES AND EQUIPMENT

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


   REAL ESTATE ACQUIRED THROUGH FORECLOSURE

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

   GOODWILL

   The excess of purchase price over the fair value of net assets of acquired
   companies is classified and reported as goodwill. Goodwill is being
   amortized using the straight-line method, over 15 years.


   DEPOSIT ACQUISITION PREMIUM

   The deposit acquisition premium arising from acquisitions is reported net of
   accumulated amortization. Such premium is being amortized on a straight-line
   basis over 10 years.


   PENSION PLAN

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


   EMPLOYEES' STOCK OWNERSHIP PLAN ("ESOP")

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


   STOCK-BASED COMPENSATION

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

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

   EARNINGS PER COMMON SHARE

   In February 1997, the Financial Accounting Standards Board ("FASB") issued
   SFAS No. 128, "Earnings Per Share." This Statement supersedes APB Opinion No.
   15 regarding the presentation of earnings per share ("EPS") on the face of
   the income statement. SFAS No. 128 replaces the presentation of Primary EPS
   with a Basic EPS calculation that excludes the dilutive effect of common
   stock equivalents. The Statement requires a dual presentation of Basic and
   Diluted EPS, which is computed similarly to Fully Diluted EPS pursuant to APB
   Opinion No. 15 for all entities with complex capital structures. This
   Statement is effective for fiscal years ending after December 15, 1997 and
   requires restatement of all prior-period EPS data presented. The adoption of
   this pronouncement did not have a material impact on the Company's earnings
   per share presentation.

           For earnings per share computations, ESOP shares that have been
   committed to be released are considered outstanding. ESOP shares that have
   not been committed to be released are not considered outstanding.

           All share information set forth herein has been adjusted to reflect
   the 4-for-3 split of the Company's common stock
   effective September 15, 1997.


   CASH AND CASH EQUIVALENTS

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

           As a nonmember of the Federal Reserve System, the Bank is required to
   maintain certain reserve requirements of vault cash and/or deposits with the
   Federal Reserve Bank of Boston. The amount of this reserve requirement,
   included in "Cash and Due from Banks," was $3.6 million and $3.2 million at
   December 31, 1997 and 1996, respectively.


   INCOME TAXES

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

           The Company and its subsidiaries file state and consolidated federal
   income tax returns on an October 31 year-end.


   TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF
   LIABILITIES

   Effective January 1, 1997, the Company adopted SFAS No. 125, "Accounting for
   Transfers and Servicing of Financial Assets and Extinguishments of
   Liabilities." This Statement is effective for transfers and servicing of
   financial assets and extinguishments of liabilities occurring after December
   31, 1996 and is to be applied prospectively. However, SFAS No. 127, "Deferral
   of the Effective Date of Certain Provisions of SFAS No. 125," requires the
   deferral of implementation as it relates to repurchase agreements,
   dollar-rolls, securities lending and similar transactions until years
   beginning after December 31, 1997. Earlier or retrospective applications of
   this Statement is not permitted. SFAS No. 125 provides accounting and
   reporting standards for transfers and servicing of financial assets and
   extinguishments of liabilities. Those standards are based on an approach that
   focuses on control, whereby after a transfer of financial assets, an entity
   recognizes the financial and servicing assets it controls and the liabilities
   it has incurred, derecognizes financial assets when control has been
   surrendered, and derecognizes liabilities when extinguished. This Statement
   provides consistent standards for distinguishing transfers of financial
   assets that are sales from transfers that are secured borrowings. The
   adoption of this pronouncement did not have a significant effect on the
   Company's financial position or results of operations.


   DISCLOSURE OF INFORMATION ABOUT CAPITAL STRUCTURE

   In February 1997, the FASB issued SFAS No. 129, "Disclosure of Information
   about Capital Structure." This Statement establishes standards for disclosing
   information about an entity's capital structure. It applies to all entities
   and is effective for reporting periods ending after December 15, 1997. The
   Company's disclosures comply with these new requirements.


   REPORTING COMPREHENSIVE INCOME

   In June 1997, the FASB issued SFAS 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.

                                                                              45
<PAGE>   23
      REPORTING COMPREHENSIVE INCOME (CONTINUED)

      Statement 130 is effective for interim and annual periods beginning after
      December 15, 1997. Earlier application is permitted. Comparative financial
      statements provided for earlier periods are required to be reclassified to
      reflect application of the provisions of the Statement. The Statement is
      not expected to have a material impact on the Company's financial
      presentation.


      DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION

      In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
      an Enterprise and Related Information." This Statement establishes
      standards for reporting information about operating segments. An operating
      segment is defined as a component of an enterprise for which separate
      financial information is available and reviewed regularly by the
      enterprise's chief operating decision maker in order to make decisions
      about resources to be allocated to the segment and also to evaluate the
      segment's performance. SFAS No. 131 requires a company to disclose certain
      balance sheet and income statement information by operating segment, as
      well as provide a reconciliation of operating segment information to the
      company's consolidated balances. This Statement is effective for reporting
      periods beginning after December 15, 1997. This Statement is not expected
      to have a material impact on the Company's financial presentation.

  5.  LOANS

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

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


                                                                              49

   8. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

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

==================================================================================================================
</TABLE>

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

  11. FAIR VALUE OF FINANCIAL INSTRUMENTS

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

      CASH AND DUE FROM BANKS, SHORT-TERM INVESTMENTS AND ACCRUED INTEREST
      RECEIVABLE

      The carrying amounts for these financial instruments approximate fair
      value because they mature in 90 days or less.

      INTEREST-BEARING DEPOSITS IN BANKS AND TERM FEDERAL FUNDS SOLD
      The carrying amounts of the interest-bearing deposits in banks and term
      federal funds sold reported in the balance sheet at December 31, 1997 and
      1996 approximate fair value.

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

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

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

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

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

              The following table presents information for loans:

  11. FAIR VALUE OF FINANCIAL INSTRUMENTS (continued)

      DEPOSIT LIABILITIES
      Under Statement 107, the fair value of deposits with no stated maturity,
      such as demand deposits, NOW accounts, regular savings and special notice
      accounts, and money market accounts, is equal to the amount payable on
      demand as of December 31, 1997 and 1996. The fair value of certificates of
      deposit is based on the discounted value of contractual cash flows. The
      discount rate is estimated using the rates currently offered for deposits
      of similar remaining maturities.

</TABLE>

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

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

              The Bank estimates the fair value of the cost to terminate
      commitments to advance funds on construction loans and for residential
      mortgage loans in the pipeline at December 31, 1997 and 1996 to be
      immaterial. Unused credit lines, including unused portions of equity lines
      of credit, are at floating interest rates and therefore there is no fair
      value adjustment.

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

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

=============================================================================================================
</TABLE>

            Based on the Company's historical and current pretax earnings,
      management believes it is more likely than not that the Company will
      realize the gross deferred tax asset existing at December 31, 1997. The
      primary sources of recovery of the gross federal deferred tax asset are
      federal income taxes paid in 1997, 1996 and 1995 that are available for
      carryback and the expectation that the existing net deductible temporary
      differences will reverse during periods in which the Company generates net
      taxable income. Since there is no carryback provision for state income tax
      purposes, management believes the existing net deductible temporary
      differences which give rise to the gross deferred state income tax asset
      will reverse during periods in which the Company generates net taxable
      income. There can be no assurance, however, that the Company will generate
      any earnings or any specific level of continuing earnings.

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

 13.  ACQUISITION (UNAUDITED)

      On July 21, 1997, MASSBANK Corp., through the Bank, acquired all the
      outstanding common stock of Glendale Co-operative Bank ("Glendale") for
      $7.38 million in cash. Glendale was a Massachusetts chartered co-operative
      bank founded in 1928 which operated from a single office in the city of
      Everett. Glendale was merged with and into the Bank on the acquisition
      date. The acquisition has been accounted for by the purchase method and,
      accordingly, the results of operations of Glendale have been included in
      MASSBANK Corp.'s consolidated financial statements from the date of
      acquisition. The excess of the purchase price over the fair value of the
      net identifiable assets acquired of $1.53 million has been recorded as
      goodwill and is being amortized on a straight line basis over 15 years.

              The following unaudited condensed pro forma financial information
      presents the combined results of operations of MASSBANK Corp. and Glendale
      as if the acquisition had occurred as of the beginning of 1997 and 1996,
      after giving effect to certain adjustments, including amortization of
      goodwill. The pro forma financial information does not necessarily reflect
      the results of operations that would have occurred had MASSBANK Corp. and
      Glendale constituted a single entity during such periods.

  15. STOCKHOLDERS' EQUITY

      The Company may not declare or pay cash dividends on its shares of common
      stock if the effect thereof would cause its stockholders' equity to be
      reduced below or to otherwise violate legal or regulatory requirements.
      Substantially all of the Company's retained earnings are unrestricted at
      December 31, 1997.

              The Bank is a Federal Deposit Insurance Corporation insured
      institution subject to the FDIC regulatory capital requirements. The FDIC
      regulations require all FDIC insured institutions to maintain minimum
      levels of Tier I capital. Highly rated banks (i.e., those with a composite
      rating of 1 under the CAMEL rating system) are required to maintain a
      minimum leverage ratio of Tier I capital to total average assets of at
      least 3.00%. An additional 100 to 200 basis points are required for all
      but these most highly rated institutions. The Bank is also required to
      maintain a minimum level of risk-based capital. Under the new risk-based
      capital standards, FDIC insured institutions must maintain a Tier I
      capital to risk-weighted assets ratio of 4.00% and are generally expected
      to meet a minimum total qualifying capital to risk-weighted assets ratio
      of 8.00%. The new risk-based capital guidelines take into consideration
      risk factors, as defined by the regulators, associated with various
      categories of assets, both on and off the balance sheet. Under the
      guidelines, capital strength is measured in two tiers which are used in
      conjunction with risk adjusted assets to determine the risk-based capital
      ratios. Tier II capital components include supplemental capital components
      such as qualifying allowance for loan losses and qualifying subordinated
      debt. Tier I capital plus the Tier II capital components is referred to as
      total qualifying capital.

              The capital ratios of the Company and its principal subsidiary
      "MASSBANK" set forth below currently exceed the minimum ratios for "well
      capitalized" banks as defined by federal regulators.

  16. EMPLOYEE BENEFITS

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

              The following table sets forth the plan's funded status and
      amounts recognized in the Company's consolidated financial statements for
      the plan years ended October 31, 1997, 1996 and 1995, the plan's latest

  16. EMPLOYEE BENEFITS (continued)

      PROFIT SHARING AND INCENTIVE COMPENSATION BONUS PLANS
      The Bank's Profit Sharing and Incentive Compensation Bonus Plans provide
      for payments to employees under certain circumstances based upon a
      year-end measurement of the Company's net income and attainment of
      individual goals and objectives by certain key officers. Payments of $417
      thousand, $418 thousand and $413 thousand were awarded under the plan in
      1997, 1996 and 1995, respectively.

      EMPLOYEE STOCK OWNERSHIP PLAN
      The Bank has an Employees' Stock Ownership Plan ("ESOP") for the benefit
      of each employee who has completed at least 1,000 hours of service with
      the Company in the previous twelve months. Under the plan, the ESOP has
      borrowed funds from a third party bank to invest in the Company's common
      stock. As this obligation will be liquidated primarily through future
      contributions to the ESOP by the Bank, the obligation is reflected as a
      liability of the Company and a reduction of stockholders' equity on the
      consolidated balance sheet. As of December 31, 1997 and 1996, such
      outstanding liabilities totaled $781 thousand and $937 thousand,
      respectively.

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

              The ESOP acquired unallocated shares in 1986 when the plan was
      first established and more recently in 1993. At December 31, 1997, the
      ESOP held 44,000 unallocated shares and 116,963 shares which have been
      allocated to participants. The fair value of the unallocated shares at
      December 31, 1997 was $2,096 thousand.

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

              Total compensation and interest expense applicable to the ESOP
      amounted to $398 thousand, $314 thousand and $303 thousand for the years
      ended December 31, 1997, 1996 and 1995, respectively.

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

      EXECUTIVE SUPPLEMENTAL RETIREMENT AGREEMENTS
      The Bank maintains executive supplemental retirement agreements for
      certain executive officers. These agreements provide retirement benefits
      designed to supplement benefits available through the Bank's retirement
      plan for employees. Total expenses for benefits payable under the
      agreements amounted to $132 thousand, $99 thousand and $94 thousand in
      1997, 1996 and 1995, respectively.

      STOCK OPTION PLAN
      Effective May 28, 1986, the Board of Directors of the Bank adopted a stock
      option plan for the benefit of its officers and other employees. In
      January, 1991, the plan was amended to authorize the grant of options to
      non-employee Directors of the Company. All but 42/3 of the 690,000 shares
      reserved for issuance under the plan were issued. On April 19, 1994,
      shareholders approved and the Bank adopted the Company's 1994 Stock
      Incentive Plan. The total number of shares of common stock that can be
      issued under this plan is 190,000 shares. Both incentive stock options and
      non-qualified stock options may be granted under the plans. As of December
      31, 1997, there were 146,760.7 non-qualified stock options and 213,439.3
      incentive stock options granted and outstanding to purchase shares under
      the plans. The maximum option term is ten years. Further stock options may
      be granted pursuant to the 1994 Stock Incentive Plan and will generally
      have an exercise price equal to, or in excess of, the fair market value of
      a share of common stock of the Company on the date the option is granted.


                                                                              61

(1)   All share information presented has been adjusted to reflect the 4-for-3
      and 3-for-2 split of the Company's common stock effective September 15,
      1997 and September 9, 1994, respectively

      As discussed in Note 1, the Company adopted SFAS No. 123 on January 1,
      1996, but continues to account for its stock option plan using the
      intrinsic value based method prescribed by APB Opinion No. 25.
      Accordingly, no compensation cost for this plan has been recognized in the
      Consolidated Statements of Income for 1997.

              In determining the pro forma disclosures required by SFAS No. 123,
      the fair value of each option grant is estimated on the date of grant
      using the Black-Scholes option-pricing model. The following table presents
      pro forma net income and earnings per share assuming the stock option plan
      was accounted for using the fair value method prescribed by SFAS No. 123,
      the weighted average assumptions used and the grant date fair value of
      options granted in 1997, 1996 and 1995:

 17.  SHAREHOLDER RIGHTS AGREEMENT

      In January, 1990, the Board of Directors adopted a Shareholders Rights
      Plan. Under the Plan, the Rights automatically become part of and trade
      with the Company's shares of common stock. Although the Rights are not
      exercisable initially, they become exercisable upon the occurrence of one
      of three triggering events as specified in the Plan. In the event they
      become exercisable, each holder of a Right would then be entitled to buy a
      unit consisting of one one-hundredth of a share of the Company's preferred
      stock at an exercise price of $70. The provisions of the Rights Plan,
      including the time periods set forth therein, generally may be extended or
      amended by the Board of Directors. The Rights will expire January 16,
      2000, but they may be redeemed at the option of the Board of Directors for
      $0.01 per Right until ten days after a person becomes a 15% shareholder of
      MASSBANK Corp. or until certain other triggering events have occurred.
