                    PAMRAPO BANCORP, INC. AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  ------------------------------------------


1.   PRINCIPLES OF CONSOLIDATION
--------------------------------

The consolidated financial statements include the accounts of Pamrapo Bancorp,
Inc. (the "Corporation") and its wholly owned subsidiaries, Pamrapo Savings
Bank, SLA (the "Bank") and Pamrapo Service Corp, Inc. The Corporation's business
is conducted principally through the Bank. All significant intercompany accounts
and transactions have been eliminated in consolidation.

2.   BASIS OF PRESENTATION
--------------------------

The accompanying unaudited consolidated financial statements were prepared in
accordance with instructions for Form 10-Q and regulations S-X and do not
include information or footnotes necessary for a complete presentation of
financial condition, results of operations, and cash flows in conformity with
generally accepted accounting principles. However, in the opinion of management,
all adjustments (consisting of normal recurring adjustments) necessary for a
fair presentation of the consolidated financial statements have been included.
The results of operations for the three months ended March 31, 1998, are not
necessarily indicative of the results which may be expected for the entire
fiscal year.

3.   NET INCOME PER COMMON SHARE
--------------------------------

Basic net income per common share is based on the weighted average number of
common shares actually outstanding. Diluted net income per share is calculated
by adjusting the weighted average number of shares of common stock outstanding
to include the effect of stock options if dilutive, using the treasury stock
method.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                 ---------------------------------------------


Changes in Financial Condition

The Corporation's assets at March 31, 1998 totalled $381.4 million, which
represents an increase of $4.7 million or 1.25% as compared with $376.7 million
at December 31, 1997.

Securities available for sale at March 31, 1998 decreased $1.2 million or 10.17%
to $10.6 million when compared with $11.8 million at December 31, 1997. The
decrease during the three months ended March 31, 1998, resulted primarily from
calls of securities available for sale of $1.0 million and repayments on
securities available for sale of $242,000.

Mortgage-backed securities held to maturity decreased $4.7 million or 3.73% to
$121.4 million at March 31, 1998 when compared to $126.1 million at December 31,
1997. The decrease during three months ended March 31, 1998, resulted from
principal repayments of $6.7 million, sufficient to offset purchases of $2.0
million.

Net loans amounted to $215.8 million at March 31, 1998 as compared to $211.2
million at December 31, 1997, which represents an increase of $4.6 million or
2.18%. The increase, during the three months ended March 31, 1998, resulted
primarily from loan originations exceeding principal repayments.

Foreclosed real estate totalled $1.41 million and $1.35 million at March 31,
1998 and December 31, 1997, respectively. During the three months ended March
31, 1998, two foreclosed real estate properties with a combined book value of
$188,000 were sold. At March 31, 1998, foreclosed real estate consisted of
nineteen properties, seven of which are under contract for sale.

Total deposits at March 31, 1998 totalled $309.1 million as compared with $307.5
million at December 31, 1997.

Advances from the Federal Home Loan Bank ("FHLB") amounted to $13.6 million at
March 31, 1998 and December 31, 1997.

Stockholders' equity totalled $48.9 million and $48.5 million at March 31, 1998
and December 31, 1997, respectively.

Comparison of Operating Results for the Three Months Ended March 31, 1998 and
1997

Net income decreased $158,000 or 12.03% to $1.155 million for the three months
ended March 31, 1998 compared with $1.313 million for the same 1997 period. The
decrease in net income during the 1998 period resulted from a decrease in
non-interest income, along with increases in total interest expense and
non-interest expenses, which were partially offset by an increase in total
interest income and decreases in provision for loan losses and income taxes.

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


Comparison of Operating Results for the Three Months Ended March 31, 1998 and
1997 (Cont'd.)

Interest income on loans increased nominally by $13,000 during the three months
ended March 31, 1998 when compared with the same 1997 period. The increase
during the 1998 period resulted from an increase of $7.3 million in the average
balance of loans outstanding sufficient to offset a twenty-eight basis point
decrease in the yield earned on the loan portfolio. Interest on mortgage-backed
securities increased $383,000 or 20.73% to $2.2 million during the three months
ended March 31, 1998 when compared with $1.8 million for the same 1997 period.
The increase during the 1998 period resulted primarily from an increase of
twenty-one basis points in the yield earned on the mortgage-backed securities
along with an increase of $19.1 million in the average balance of such portfolio
outstanding. Interest earned on investments and other interest-earning assets
decreased by $128,000 or 35.36% to $234,000 during the three months ended March
31, 1998, when compared to $362,000 during the same 1997 period primarily due to
a decrease of $10.0 million in the average balance of such assets outstanding
sufficient to offset a forty-six basis point increase in the yield earned on
such portfolio.

Interest expense on deposits increased $88,000 or 3.23% to $2.8 million during
the three months ended March 31, 1998 when compared to $2.7 million during the
same 1997 period. Such increase was primarily attributable to increases of $2.3
million in the average balance of interest-bearing deposits and ten basis points
in the cost of interest-bearing deposits. Interest expense on advances and other
borrowed money increased by $149,000 or 209.86% to $220,000 during the three
months ended March 31, 1998 when compared with $71,000 during the same 1997
period, primarily due to an increase of $9.7 million in the average balance of
advances outstanding from the FHLB sufficient to offset an eighty-six basis
point decrease in the cost of advances and other borrowed money.

Net interest income increased $32,000 or .77% during the three months ended
March 31, 1998 when compared with the same 1997 period. Such increase was due to
an increase in total interest income of $269,000, sufficient to offset an
increase in total interest expense of $237,000. The Bank's net interest rate
spread decreased from 4.28% in 1997 to 4.06% in 1998. The decrease in the
interest rate spread resulted from a decrease of six basis points in the yield
earned on interest-earning assets along with a sixteen basis point increase in
the cost of interest-bearing liabilities.

During the three months ended March 31, 1998 and 1997, the Bank provided $75,000
and $150,000, respectively, as a provision for loan losses. The allowance for
loan losses is based on management's evaluation of the risk inherent in its loan
portfolio and gives due consideration to the changes in general market
conditions and in the nature and volume of the Bank's loan activity. The Bank
intends to continue to provide for loan losses based on its periodic review of
the loan portfolio and general market conditions. At March 31, 1998, December
31, 1997 and March 31, 1997, the Bank's non-performing loans, which were
delinquent ninety days or more, totalled $6.0 million or 1.57% of total assets,
$6.9 million or 1.83% of total assets and $11.5 million or 3.13% of total
assets, respectively. At March 31, 1998, $900,000 of non-performing loans were
accruing interest and $5.1 million were on non-accrual status. During the three
months ended March 31, 1998 and 1997, the Bank transferred $261,000 and
$151,000, respectively, of loans to foreclosed real estate. The non-performing
loans primarily consist of one-to-four family mortgage loans. During the three
months ended March 31, 1998 and 1997, the Bank charged off loans aggregating
$133,000 and $186,000, respectively. The allowance for loan losses amounted to
$2.4 million at March 31, 1998, representing 1.10% of total loans and 40.4% of
loans delinquent ninety days or more and $2.5 million at December 31, 1997,
representing 1.15% of total loans and 35.6% of loans delinquent ninety days or
more.

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


Comparison of Operating Results for the Three Months Ended March 31, 1998 and
1997 (Cont'd.)

Non-interest income decreased $58,000 or 14.61% to $339,000 during the three
months ended March 31, 1998 from $397,000 during the same 1997 period. The
decrease resulted from decreases in gain on sales of mortgage-backed securities
of $112,000 sufficient to offset increases in fees and service charges and
miscellaneous income of $17,000 and $37,000, respectively.

Non-interest expenses increased by $303,000 or 13.10% to $2.6 million during the
three months ended March 31, 1998 when compared with $2.3 million during the
same 1997 period. Salaries and employee benefits, net occupancy expense,
equipment, and miscellaneous expenses increased $209,000, $36,000, $39,000 and
$50,000, respectively, which was sufficient to offset decreases in advertising,
loss on foreclosed real estate and federal insurance premium of $4,000, $26,000
and $1,000, respectively, during the 1998 period when compared with the same
1997 period. The increase in salaries and employee benefits resulted from, in
addition to normal increases, the costs associated with the opening of two new
branch offices in Brick, New Jersey.

Income taxes totalled $666,000 and $762,000 during the three months ended March
31, 1998 and 1997, respectively. The decrease during the 1998 period resulted
from a decrease in pre-tax income.

Liquidity and Capital Resources

The Bank is required to maintain minimum levels of liquid assets as defined by
the Office of Thrift Supervision (the "OTS") regulations. This requirement,
which may vary from time to time, depending upon economic conditions and deposit
flows, is based upon a percentage of deposits and short-term borrowings. The
required ratio currently is 4%. The Bank's liquidity averaged 7.48% during the
month of March 1998. The Bank adjusts its liquidity levels in order to meet
funding needs for deposit outflows, payment of real estate taxes from escrow
accounts on mortgage loans, repayment of borrowings, when applicable and loan
funding commitments. The Bank also adjusts its liquidity level as appropriate to
meet its asset/liability objectives.

The Bank's primary sources of funds are deposits, amortization and prepayments
of loans and mortgage-backed securities principal, FHLB advances, maturities of
investment securities and funds provided from operations. While scheduled loan
and mortgage-backed securities amortization and maturing investment securities
are a relatively predictable source of funds, deposit flow and loan and
mortgage-backed securities prepayments are greatly influenced by market interest
rates, economic conditions and competition. The Bank invests its excess funds in
federal funds and overnight deposits with the FHLB, which provides liquidity to
meet lending requirements. Interest-bearing deposits at March 31, 1998 amounted
to $10.0 million.

Cash was generated by operating activities during the three months ended March
31, 1998. The primary source of cash was net income. Cash dividends paid during
the three months ended March 31, 1998 and 1997 amounted to $796,000 and
$794,000, respectively.

The primary sources of investing activity of the Bank are lending and the
purchase of mortgage-backed securities. Net loans amounted to $215.8 million and
$211.2 million at March 31, 1998 and December 31, 1997, respectively. Securities
available for sale totalled $10.6 million and $11.8 million at March 31, 1998
and December 31, 1997, respectively. Mortgage-backed securities held to maturity
totalled $121.4 million and $126.1 million at March 31, 1998 and December 31,
1997, respectively. In addition to funding new loan production and
mortgage-backed securities purchases through operations and financing
activities, such activities were funded by principal repayments on existing
loans and mortgage-backed securities.

Liquidity management is both a daily and long-term function of business
management. Excess liquidity is generally invested in short-term investments,
such as federal funds and interest-bearing deposits. If the Bank requires funds
beyond its ability to generate them internally, borrowing agreements exist with
the FHLB which provide an additional source of funds. At March 31, 1998,
advances from the FHLB amounted to $13.6 million.

Liquidity and Capital Resources (Cont'd.)

The Bank anticipates that it will have sufficient funds available to meet its
current loan commitments. At March 31, 1998, the Bank has outstanding
commitments to originate mortgage loans of $16.2 million. Certificates of
deposit scheduled to mature in one year or less at March 31, 1998, totalled
$118.2 million. Management believes that, based upon its experience and the
Bank's deposit flow history, a significant portion of such deposits will remain
with the Bank.

Under OTS regulations, three separate measurements of capital adequacy (the
"Capital Rule") are required. The Capital Rule requires each savings institution
to maintain tangible capital equal to at least 1.5% and core capital equal to
4.0% of its adjusted total assets. The Capital rule further requires each
savings institution to maintain total capital equal to at least 8.0% of its
risk-weighted assets.

The following table sets forth the Bank's capital position at March 31, 1998, as
compared to the minimum regulatory capital requirements:

Thrift Rechartering Legislation

The proposed legislation regarding elimination of the federal thrift charter and
related issues remains pending before Congress. The Bank, whose deposits are
insured by Savings Associations Insurance Fund ("SAIF"), is unable to predict
whether such legislation will be enacted, the extent to which the legislation
would restrict or disrupt its operations or whether the Bank Insurance Fund
("BIF") or SAIF funds will eventually merge.

Supervisory Examination

The Bank's financial statements are periodically examined by the OTS, the
Federal Deposit Insurance Corporation ("FDIC") and the New Jersey Department of
Banking and Insurance, as part of their regulatory oversight of the thrift
industry. As a result of these examinations, the regulators can direct that the
Bank make adjustments to its financial statements based on their findings.

Impact of the Year 2000 Issue

The Year 2000 Issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Any of the Bank's
computer programs that would have date sensitive software may recognize a date
during "00" as the year 1900 rather than the year 2000. This could result in a
system failure or miscalculations causing disruptions of operations, including
among other things, a temporary inability to process transactions, or engage in
similar normal business activities.

Based on a recent assessment, the Bank has determined that it will be required
to modify or replace portions of its software so that its computer systems will
properly utilize dates beyond December 31, 1999. The Bank presently believes
that with modifications to existing software and conversion to new software, the
year 2000 Issue can be mitigated. However, if such modifications and conversions
are not made, or are not completed timely, the Year 2000 Issue may have a
material impact on the operations of the Bank.

The Bank has initiated formal communications with all or its significant
suppliers and vendors to determine the extent to which the Bank is vulnerable to
those third parties failure to remediate their own Year 2000 Issues. The Bank
will utilize both internal and external resources to reprogram, or replace, and
test the software for year 2000 modifications. The Bank expects to complete the
Year 2000 project no later than December 31, 1998. The Bank is in the process of
determining the costs and time associated with the Year 2000 project. The Bank
does not expect that the total cost of the Year 2000 project will have a
material adverse impact on the financial condition or operations of the Bank. To
date, the Bank has not incurred or expensed any material amount related to the
assessment of, and preliminary efforts in connection with, its Year 2000 project
and the development of a remediation plan.

        QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK



Management of Interest Rate Risk. The ability to maximize net interest income is
largely dependent upon the achievement of a positive interest rate spread that
can be sustained during fluctuations in prevailing interest rates. Interest rate
sensitivity is a measure of the difference between amounts of interest-earning
assets and interest-bearing liabilities which either reprice or mature within a
given period of time. The difference, or the interest rate repricing "gap",
provides an indication of the extent to which an institution's interest rate
spread will be affected by changes in interest rates. A gap is considered
positive when the amount of interest-rate sensitive assets exceeds the amount of
interest-rate sensitive liabilities, and is considered negative when the amount
of interest rate sensitive liabilities exceeds the amount of interest-rate
sensitive assets. Generally, during a period of rising interest rates, a
negative gap within shorter maturities would adversely affect net interest
income, while a positive gap within shorter maturities would result in an
increase in net interest income, and during a period of falling interest rates,
a negative gap within shorter maturities would result in an increase in net
interest income while a positive gap within shorter maturities would result in a
decrease in net interest income.

Because the Bank's interest-bearing liabilities which mature or reprice within
short periods exceed its interest-earning assets with similar characteristics,
material and prolonged increases in interest rates generally would adversely
affect net interest income, while material and prolonged decreases in interest
rates generally would have a positive effect on net interest income.

The Bank's current investment strategy is to maintain an overall securities
portfolio that provides a source of liquidity and that contributes to the Bank's
overall profitability and asset mix within given quality and maturity
considerations. The securities portfolio is concentrated in U.S. Treasury and
federal government agency securities providing high asset quality to the overall
balance sheet mix. Securities classified as available for sale provide
management with the flexibility to make adjustments to the portfolio given
changes in the economic or interest rate environment, to fulfill unanticipated
liquidity needs, or to take advantage of alternative investment opportunities.

Net Portfolio Value. The Bank's interest rate sensitivity is monitored by
management through the use of the OTDS model which estimates the change in the
Bank's net portfolio value ("NPV") over a range of interest rate scenarios. NPV
is the present value of expected cash flows from assets, liabilities, and
off-balance sheet contracts. The NPV ratio, under any interest rate scenario, is
defined as the NPV in that scenario divided by the market value of assets in the
same scenario. The OTS produces its analysis based upon data submitted on the
Bank's quarterly Thrift Financial Reports. The following table sets forth the
Bank's NPV as of December 31, 1997, the most recent date the Bank's NPV was
calculated by the OTS.

Certain shortcomings are inherent in the methodology used in the above interest
rate risk measurements. Modeling changes in NPV require the making of certain
assumptions which may or may not reflect the manner in which actual yields and
costs respond to changes in market interest rates. In this regard, the NPV model
presented assumes that the composition of the Bank's interest sensitive assets
and liabilities existing at the beginning of a period remains constant over the
period being measured and also assumes that a particular change in interest
rates is reflected uniformly across the yield curve regardless of the duration
to maturity or repricing of specific assets and liabilities. Accordingly,
although the NPV measurements and net interest income models provide an
indication of the Bank's interest rate risk exposure at a particular point in
time, such measurements are not intended to and do not provide a precise
forecast of the effect of changes in market interest rates on the Bank's net
interest income and will differ from actual results.
