                   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 regulation 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 and nine months ended September 30, 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 September 30, 1998 totalled $397.2 million, which
represents an increase of $20.5 million  or 5.44% as compared with $376.7
million at December 31, 1997.

Cash and cash equivalents increased $8.4 million or 63.16% to $21.7 million at
September 30, 1998 from $13.3 million at December 31, 1997, resulting primarily
from an increase of $7.9 million in short-term interest-bearing deposits.

Securities available for sale at September 30, 1998 decreased $1.8 million or
15.25% to $10.0 million when compared with $11.8 million at December 31, 1997.
The decrease during the nine months ended September 30, 1998, resulted primarily
from calls of securities available for sale of $1.0 million and repayments on
securities available for sale of $908,000, sufficient to offset purchases of
securities available for sale of $52,000.

Mortgage-backed securities held to maturity decreased $2.4 million or 1.90% to
$123.7 million at September 30, 1998 when compared to $126.1 million at December
31, 1997. The decrease during the nine months ended September 30, 1998, resulted
from principal repayments of $23.0 million sufficient to offset purchases of
$20.7 million.

Net loans amounted to $227.9 million at September 30, 1998 as compared to $211.2
million at December 31, 1997, which represents an increase of $16.7 million or
7.91%.  The increase, during the nine months ended September 30, 1998, resulted
primarily from loan originations and purchases exceeding principal repayments.

Foreclosed real estate totalled $1.1 million  and $1.4 million at September 30,
1998 and December 31, 1997, respectively.  During the nine months ended
September 30, 1998, ten foreclosed real estate properties with a combined book
value of $770,000 were sold resulting in a gain of $41,000. At September 30,
1998, foreclosed real estate consisted of fourteen properties, five of which are
under contract for sale.

Total deposits at September 30, 1998 totalled $314.6 million as compared with
$307.5 million at December 31, 1997, representing an increase of $7.1 million
or 2.31%.

Advances from the Federal Home Loan Bank of New York  ("FHLB") amounted to $23.6
million and $13.6 million at September 30, 1998 and December 31, 1997,
respectively.  The increase, during the nine months ended September 30, 1998,
resulted from new advances from the FHLB of $10.0 million, which were used for
general corporate purposes.

Stockholders' equity totalled $49.5 million and $48.5 million at September 30,
1998 and December 31, 1997, respectively.

Comparison of Operating Results for the Three Months Ended September 30, 1998
and 1997

Net income decreased $173,000 or 13.68% to $1.1 million for the three months
ended September 30, 1998 compared with $1.3 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 interest income
and decreases in provision for loan losses and income taxes.

Comparison of Operating Results for the Three Months Ended September 30, 1998
and 1997 (Cont'd.)

Interest income on loans increased by $289,000 or 6.26% to $4.9 million during
the three months ended September 30, 1998 when compared with $4.6 million during
the same 1997 period.  The increase during the 1998 period resulted from an
increase of $20.0 million in the average balance of loans outstanding sufficient
to offset a twenty-nine basis point decrease in the yield earned on the loan
portfolio.  Interest on mortgage-backed securities decreased $305,000 or 13.30%
to $2.0 million during the three months ended September 30, 1998 when compared
with $2.3 million for the same 1997 period.  The decrease during the 1998 period
resulted from a decrease of thirty-one basis points in the yield earned on the
mortgage-backed securities outstanding along with a decrease of $12.3 million in
the average balance of such portfolio outstanding.  Interest earned on
investments and other interest-earning assets increased by $130,000 or 58.56% to
$352,000 during the three months ended September 30, 1998, when compared to
$222,000 during the same 1997 period primarily due to an increase of $9.0
million in the average balance of such assets outstanding sufficient to offset a
forty-five basis point decrease in the yield earned on such portfolio.

Interest expense on deposits increased $45,000 or 1.62% to $2.826 million during
the three months ended September 30, 1998 when compared to $2.781 million during
the same 1997 period.  Such increase was primarily attributable to an increase
of $9.8 million in the average balance of interest-bearing deposits sufficient
to offset a six basis point decrease in the cost of interest-bearing deposits.
Interest expense on advances and other borrowed money increased by $19,000 or
7.76% to $264,000 during the three months ended September 30, 1998 when compared
with $245,000 during the same 1997 period, primarily due to a six basis point
increase in the cost of advances and other borrowed money along with an increase
of $1.0 million in the average balance of advances and other borrowed money
outstanding.

Net interest income increased $50,000 or 1.22% during the three months ended
September 30, 1998 when compared with the same 1997 period. Such increase was
due to an increase in total interest income of $114,000, sufficient to offset an
increase in total interest expense of $64,000. The Bank's net interest rate
spread decreased from 4.10% in 1997 to 3.91% in 1998.  The decrease in the
interest rate spread resulted from a decrease of twenty-four basis points in the
yield earned on interest-earning assets which more than offset a five basis
point decrease in the cost of interest-bearing liabilities.

During the three months ended September 30, 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 the Bank's 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
September 30, 1998, December 31, 1997 and September 30, 1997, the Bank's non-
performing loans, which were delinquent ninety days or more, totalled $5.0
million or 1.27% of total assets, $6.9 million or 1.83% of total assets and $7.5
million  or 2.00% of total assets, respectively.  At September 30, 1998,
$865,000 of non-performing loans were accruing interest and $4.2 million were on
nonaccrual status.  During the three months ended September 30, 1998 and 1997,
the Bank transferred $143,000 and $445,000, 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 September 30, 1998 and 1997, the
Bank charged off loans aggregating $33,000 and $298,000, respectively.  The
allowance for loan losses amounted to $2.4 million at September 30, 1998,
representing 1.02% of total loans and 46.99% of loans delinquent ninety days or
more and $2.5 million at December 31, 1997, representing 1.15% of total loans
and 35.64% of loans delinquent ninety days or more.

Comparison of Operating Results for the Three Months Ended September 30, 1998
and 1997 (Cont'd.)

Non-interest income decreased $11,000 or 2.95% to $362,000 during the three
months ended September 30, 1998 from $373,000 during the same 1997 period. The
decrease, during the 1998 period resulted from a decrease of $27,000 in
miscellaneous income sufficient to offset an increase of $16,000 in fees and
service charges.

Non-interest expenses increased by $329,000 or 13.70% to $2.7 million during the
three months ended September 30, 1998 when compared with $2.4 million during
the same 1997 period.  Salaries and employee benefits, net occupancy expense,
equipment and advertising expenses increased $263,000, $47,000, $51,000, and
$62,000, respectively, sufficient to offset decreases in loss on foreclosed real
estate, federal insurance premium and miscellaneous expenses of $59,000, $5,000,
and $30,000, respectively, during the 1998 period when compared with the same
1997 period.  The 1998 non-interest expenses include increased operating costs
resulting from two Brick, New Jersey offices opened after September 30, 1997.

Income taxes totalled $623,000 and $665,000 during the three months ended
September 30, 1998 and 1997, respectively. The decrease during the 1998 period
resulted from a decrease in pre-tax income.

Comparison of Operating Results for the Nine Months Ended September 30, 1998 and
1997

Net income decreased $552,000 or 14.38% to $3.3 million for the nine months
ended September 30, 1998 compared with $3.8 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 interest income
and decreases in provision for loan losses and income taxes.

Interest income on loans increased by $436,000 or 3.12% to $14.4 million during
the nine months ended September 30, 1998 when compared with $14.0 million during
the same 1997 period. The increase during the 1998 period resulted from an
increase of $13.9 million in the average balance of loans outstanding sufficient
to offset a thirty-one basis point decrease in the yield earned on the loan
portfolio. Interest on mortgage-backed securities decreased $45,000 or .71% to
$6.3 million during the nine months ended September 30, 1998 when compared with
$6.4 million for the same 1997 period. The decrease during the 1998 period
resulted from a decrease of eleven basis points in the yield earned on the
mortgage-backed securities outstanding sufficient to offset an increase of $1.3
million in the average balance of such portfolio outstanding. Interest earned on
investments and other interest-earning assets decreased by $37,000 or 4.19% to
$847,000 during the nine months ended September 30, 1998, when compared to
$884,000 during the same 1997 period primarily due to a decrease of $893,000 in
the average balance of such assets outstanding sufficient to offset a four basis
point increase in the yield earned on such portfolio.

Interest expense on deposits increased $203,000 or 2.46% to $8.5 million during
the nine months ended September 30, 1998 when compared to $8.3 million during
the same 1997 period. Such increase was primarily attributable to an increase of
$7.0 million in the average balance of interest-bearing deposits along with a
one basis point increase in the cost of interest-bearing deposits. Interest
expense on advances and other borrowed money increased by $160,000 or 29.25% to
$707,000 during the nine months ended September 30, 1998 when compared with
$547,000 during the same 1997 period, primarily due to an increase of $3.8
million in the average balance of advances and other borrowed money outstanding
sufficient to offset a thirty basis point decrease in the cost of advances and
other borrowed money.

Comparison of Operating Results for the Nine Months Ended September 30, 1998 and
1997 (Cont'd.)

Net interest income decreased $8,000 during the nine months ended September 30,
1998 when compared with the same 1997 period.  Such decrease was due to an
increase in total interest expense of $363,000, sufficient to offset an increase
in total interest income of $354,000. The Bank's net interest rate spread
decreased from 4.19% in 1997 to 3.98% in 1998.  The decrease in the interest
rate spread resulted from a decrease of nineteen basis points in the yield
earned on interest-earning assets along with a two basis point increase in the
cost of interest-bearing liabilities.

During the nine months ended September 30, 1998 and 1997, the Bank provided
$225,000 and $450,000, 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
September 30, 1998, December 31, 1997 and September 30, 1997, the Bank's non-
performing loans, which were delinquent ninety days or more, totalled $5.0
million or 1.27% of total assets, $6.9 million or 1.83% of total assets and $7.5
million or 2.00% of total assets, respectively.  At September 30, 1998, $865,000
of non-performing loans were accruing interest and $4.2 million were on non-
accrual status.  During the nine months ended September 30, 1998 and 1997, the
Bank transferred $608,000 and $894,000, respectively, of loans to foreclosed
real estate. The non-performing loans primarily consist of one-to-four family
mortgage loans.  During the nine months ended September 30, 1998 and 1997, the
Bank charged off loans aggregating $343,000 and $733,000, respectively.  The
allowance for loan losses amounted to $2.4 million at September 30, 1998,
representing 1.02% of total loans and 46.99% of loans delinquent ninety days or
more and $2.5 million at December 31, 1997, representing 1.15% of total loans
and 35.64% of loans delinquent ninety days or more.

Non-interest income decreased $50,000 or 4.74% to $1.0 million during the nine
months ended September 30, 1998 from $1.1 million during the same 1997 period.
The decrease resulted from a decrease in gain on sale of mortgage-backed
securities of $112,000 sufficient to offset increases in fees and service
charges and miscellaneous income of $36,000 and $26,000, respectively.

Non-interest expenses increased by $1.0 million or 14.61% to $8.0 million during
the nine months ended September 30, 1998 when compared with $7.0 million during
the same 1997 period. Salaries and employee benefits, net occupancy expense,
equipment, advertising, and miscellaneous expenses increased $660,000, $160,000,
$138,000, $82,000, and $65,000, respectively, sufficient to offset decreases in
federal insurance premium and loss on foreclosed real estate of $3,000 and
$79,000, respectively, during the 1998 period when compared with the same 1997
period. The 1998 non-interest expenses include increased operating costs
resulting from two Brick, New Jersey offices opened after September 30, 1997.

Income taxes totalled $1.9 million and $2.2 million during the nine months ended
September 30, 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 4.0%. The Bank's liquidity averaged 8.04% during the
month of September 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 September 30, 1998
amounted to $10.8 million.

The Bank's liquidity, represented by cash and cash equivalents, is a product of
its operating, investing and financing activities.  These activities are
summarized below:

Liquidity and Capital Resources (Cont'd.)

Cash was generated by operating activities during the nine months ended
September 30, 1998. The primary source of cash was net income.  Cash dividends
paid during the nine months ended September 30, 1998 and 1997 amounted to $2.4
million and $2.2 million, respectively.

The primary sources of investing activity of the Bank are lending and the
purchase of mortgage-backed securities.  Net loans amounted to $227.9 million
and $211.2 million at September 30, 1998 and December 31, 1997, respectively.
Securities available for sale totalled $10.0 million and $11.8 million at
September 30, 1998 and December 31, 1997, respectively. Mortgage-backed
securities held to maturity totalled $123.7 million and $126.1 million at
September 30, 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 provides an additional source of funds.  At September 30, 1998,
advances from the FHLB amounted to $23.6 million.

The Bank anticipates that it will have sufficient funds available to meet its
current loan commitments.  At September 30, 1998, the Bank has outstanding
commitments to originate mortgage loans of $11.4 million. Certificates of
deposit scheduled to mature in one year or less at September 30, 1998, totalled
$120.0 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.

Thrift Rechartering Legislation

The proposed legislation regarding elimination of the 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 would 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 of 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 March 31, 1999. 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.

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.  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 June 30,
1998, 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.
