CCFNB BANCORP, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
MARCH 31, 1999
UNAUDITED


BASIS OF PRESENTATION

NOTE 1 - The accounting and reporting policies of CCFNB Bancorp and its
         subsidiary conform to generally accepted accounting principles and to
         general practices within the banking industry. These consolidated
         interim financial statements include the accounts of CCFNB Bancorp,
         Inc. and its wholly owned subsidiary, Columbia County Farmers National
         Bank. All significant inter-company balances have been eliminated.

NOTE 2 - The accompanying consolidated interim financial statements are
         unaudited. In management's opinion, the consolidated interim financial
         statements reflect a fair presentation of the consolidated financial
         position of CCFNB Bancorp, Inc. and Subsidiary, the results of their
         operations and their cash flows for the interim periods presented.
         Further, the consolidated interim financial statements reflect all
         adjustments, which are in the opinion of management, necessary to
         present fairly the consolidated financial condition and consolidated
         results of operations and cash flows for the interim period presented
         and that all such adjustments to the consolidated financial statements
         are of a normal recurring nature.

NOTE 3 - The results of operations for the three month period ended March
         31, 1999 are not necessarily indicative of the results to be expected
         for the full year.

NOTE 4 - Net income per share of common stock for the interim periods is
         based on the weighted average number of shares for each period; 1999 -
         1,375,768 shares and 1998 - 1,379,506 shares.

NOTE 5 - LOANS

         Loans are stated at their outstanding principal balances, net of any
         deferred fees or costs, unearned income, and the allowance for loan
         losses. Interest on loans is accrued on the principal amount
         outstanding, primarily on an actual day basis. Non-refundable loan fees
         and certain direct costs are deferred and amortized over the life of
         the loans using the interest method. The amortization is reflected as
         an interest yield adjustment, and the deferred portion of the net fees
         and costs is reflected as a part of the loan balance.

         Non-Accrual Loans - Generally, a loan is classified as non-accrual, and
         the accrual of interest on such a loan is discontinued when the
         contractual payment of principal or interest has become 90 days past
         due or management has serious doubts about further collectibility of
         principal or interest, even though the loan currently is performing. A
         loan may remain on accrual status if it is in the process of collection
         and is either guaranteed or well secured. When a loan is placed on
         non-accrual status, unpaid interest credited to income in the current
         year is reversed, and unpaid interest accrued in prior years is charged
         against the allowance for credit losses. Certain non-accrual loans may
         continue to perform, that is, payments are still being received.
         Generally, the payments are applied to principal. These loans remain
         under constant scrutiny and if performance continues, interest income
         may be recorded on a cash basis based on management's judgement as to
         collectibility of principal.

         Allowance for Loan Losses - The allowance for loan losses is
         established through provisions for loan losses charged against income.
         Loans deemed to be uncollectible are charged against the allowance for
         loan losses, and subsequent recoveries, if any, are credited to the
         allowance.

         A principal factor in estimating the allowance for loan losses is the
         measurement of impaired loans. A loan is considered impaired when,
         based on current information and events, it is probable that the
         Corporation will be unable to collect all amounts due according to the
         contractual terms of the loan agreement. Under current accounting
         standards, the allowance for loan losses related to impaired loans is
         based on discounted cash flows using the loan's effective interest rate
         or the fair value of the collateral for certain collateral dependent
         loans.

         The allowance for loan losses is maintained at a level established by
         management to be adequate to absorb estimated potential loan losses.
         Management's periodic evaluation of the adequacy of the allowance for
         loan losses is based on the Corporation's past loan loss experience,
         known and inherent risks in the portfolio, adverse situations that may
         affect the borrower's ability to repay (including the timing of future
         payments), the estimated value of any underlying collateral,
         composition of the loan portfolio, current economic conditions, and
         other relevant factors. This evaluation is inherently subjective as it
         requires material estimates, including the amounts and timing of future
         cash flows expected to be received on impaired loans that may be
         susceptible to significant change.


         The following table presents the changes in the allowance for credit
         losses:

</TABLE>

         At March 31, 1999 no loans were considered impaired as defined by
         Statement No. 114. Accordingly, no additional charge to operations was
         required since the total allowance for loan losses was estimated by
         management to be adequate to provide for the loan loss allowance under
         Statement No. 114 as well as any other potential loan losses.

The following discussion and analysis of the financial condition and results of
operations of the Corporation should be read in conjunction with the
consolidated financial statements of the Corporation. The consolidated financial
condition and results of operations of the Corporation are essentially those of
the Bank. Therefore, the discussion and analysis that follows is directed
primarily at the performance of the Bank.

Overview
--------

Total assets decreased .8% to $183.8 million at March 31, 1999, from $185.3
million at December 31, 1998. Net income increased 6.1% through March 31, 1999
to $451,000 or $.33 per share, compared to $425,000 or .31 per share for the
same three month period ended March 31, 1998. Loans increased in 1999 by .3% to
$118.9 million at March 31, from $118.6 million at December 31, 1998.

Results of Operations - For the Three Months Ended March 31, 1999 and March 31,
1998.

Net income is affected by five major components: net interest income or the
difference between interest income earned on loans and investments and interest
expense paid on deposits and borrowed funds; the provision for loan losses,
which is the amount charged against net interest income and added to the
allowance for loan losses to provide a reserve for potential future loan losses;
other non-interest income, which is made up of certain fees, gains and losses
from the sale of investment securities, trust department income and other items;
and other non-interest expenses, which consist primarily of salaries and
benefits, general overhead expenses, other operational expenses and income
taxes. Each of these major components is reviewed in more detail in the
following discussion.

Net income for the three months ended March 31, 1999 was $451,000, or $.33 per
share, as compared to $425,000, or $.31 per share, for the comparable period in
1998. The principal factor for the increase was due to gains on sales of
securities of $31,000 during the first quarter 1999.

Return on average assets and return on average equity were .98% and 7.74%,
respectively, for the three months ended March 31, 1999, as compared to .97% and
7.70%, respectively, for the comparable period in 1998.

Net Interest Income
-------------------

For the three months ended March 31, 1998 and 1999, net interest income was $1.6
million. The net interest margin reflected a decrease to 3.85% for the three
months ended March 31, 1999 from 4.10% for the comparable period in 1998.
Average interest earning assets at March 31, 1999 increased by 5.53% over March
31, 1998.

Average loans outstanding increased from $117.4 million to $118.8 million or
1.2% for the three months ended March 31, 1999, as compared to the three months
ended March 31, 1998. The outstanding balance of loans at March 31, 1999,
increased from $118.6 million at December 31, 1998 to $118.9 million at March
31, 1999. A 4.1% decrease in income on loans from $2,425 million at March 31,
1998 to $2,325 million at March 31, 1999 occurred even though the loans
increased during the period.

</TABLE>

Past due and non-accrual loans increased 35.0% from $2.0 million at December 31,
1998 to $2.7 million at March 31, 1999. These real estate delinquencies mainly
fall into the 60 day and below category. The increase specifically was
attributable entirely to real estate loans which become past due during the
quarter which are fully secured by adequate real estate collateral.

Any loans classified for regulatory purposes as loss, doubtful, substandard, or
special mention that have not been disclosed under Industry Guide 3 do not (i)
represent or result from trends or uncertainties which management reasonably
expects will materially impact future operating results, liquidity, or capital
resources, or (ii) represent material credits about which management is aware of
any information which causes management to have serious doubts as to the ability
of such borrowers to comply with the loan repayment terms.

The Corporation adheres to principles provided by Financial Accounting Standards
Board Statement No. 114, "Accounting by Creditors for Impairment of a Loan" -

Interest income from investment securities reflects an 8.8% increase comparing
$667,000 for the three months ended March 31, 1999, and the $613,000 for the
comparable period of 1998. The average balance of investment securities for the
three months ended March 31, 1999 increased 15.2% to $49.3 million, compared to
the $42.8 million for the same period of 1998.

Total interest expense decreased $7,000 or .5% for the first three months of
1999, as compared to the first three months of 1998. This decrease in interest
expense reflects a decrease in interest rates throughout the past year.

The following table sets forth, for the periods indicated, information
regarding: (1) the total dollar amount of interest income from interest-earning
assets and the resultant average yields; (2) the total dollar amount of interest
expense on interest-bearing liabilities and the resultant average cost; (3) net
interest income; (4) net interest margin; (5) tax equivalent net interest
income; and (6) tax equivalent net interest margin. Information is based on

(5)  Interest and yield are presented on a tax-equivalent basis using 34%
         for 1999 and 1998.

Provision for Loan Losses
-------------------------

The provision for loan losses is based on management's evaluation of the
allowance for loan losses in relation to the credit risk inherent in the loan
portfolio. In establishing the amount of the provision required, management
considers a variety of factors, including but not limited to, general economic
conditions, volumes of various types of loans, collateral adequacy and potential
losses from significant borrowers. On a monthly basis, the Board of Directors
and the Credit Administration Committee review information regarding specific
loans and the total loan portfolio in general in order to determine the amount
to be charged to the provision for loan losses.

For the three month period ending March 31, 1999 and 1998, the provision for
loan losses was $20,000.

</TABLE>

For the three months ended March 31, 1999, total non-interest income increased
$55,000, to $249,000 compared with $194,000 for the three months ended March 31,
1998. The increase is generally the result of gains on sales of securities,
reflecting $31,000 in gains. In addition, gross commission income earned as a
result of brokerage and investment services increased $18,000 at March 31, 1999
compared to March 31, 1998. The net income derived from this operation after
recognition of payroll, commissions and other expenses was $4,000 for the first
three months of 1999 compared to $0 for the first three months of 1998.

Non-Interest Expenses
---------------------

Generally, non-interest expense accounts for the cost of maintaining facilities,
providing salaries and necessary benefits to employees, and general operating
costs such as insurance, supplies, advertising, data processing services, taxes
and other related expenses. Some of the costs and expenses are variable while
others are fixed. To the extent possible, the Company utilizes budgets and
related measures to control variable expenses. The following table sets forth,
for the periods indicated, the major components of non-interest expenses:

Salary and employee benefits expense increased 1.0% due primarily to employee
annual increases and promotions within the Bank. Shares tax increased 15% as a
result of a normal increase in shareholders' equity and a shift in the
composition of the investment portfolio. Furniture and equipment expense
increased 7.7% for the first three months of 1999 compared to the firs three
months of 1998 due to equipment depreciation and maintenance resulting from our
in-house computer system beginning in April 1998. Overall, expenses decreased
 .6% reflecting the commitment of management to remain vigilant in keeping
expenses down.

Capital
-------

A major strength of a financial institution is a strong capital position. This
capital is very critical as it must provide growth, payment to shareholders, and
absorption of unforeseen losses. The federal regulators provide standards that
must be met. These standards measure "risk-adjusted" assets against different
categories of capital. The "risk-adjusted" assets reflect off balance sheet
items, such as commitments to make loans, and also place balance sheet assets on
a "risk" basis for collectibility. The adjusted assets are measured against Tier
I Capital and Total Qualifying Capital. Tier I Capital is common shareholders'
equity and Tier II Capital includes the allowance for loan losses. Allowance for
loan losses must be lower than or equal to common shareholders' equity to be
eligible for Total Qualifying Capital.

The Company exceeds all minimum capital requirements as reflected in the
following table:

Year 2000
---------

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 have date-sensitive software may recognize a date using
"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, send invoices,
calculate correct accruals, or engage in similar normal business activities.

An assessment of the Bank's software and hardware has revealed those portions
which will be required to be modified or replaced in order to properly utilize
dates beyond December 31, 1999. The Bank presently believes that the Year 2000
is near resolution.

Another consideration for the imminent year 2000 readiness are embedded
microchip problems. These microchips could be in such items as water pumps,
sewage pumps, elevators, heat pumps, etc. A survey of all equipment containing
possible microchips has been conducted at all CCFNB locations. Plumbing and
heating vendors have been contacted as well as the telephone service providers.
"White papers" indicating Y2K readiness have been obtained from all providers.

Another consideration is the fact that there can be no guarantee that the
systems of other companies on which the Bank's systems rely will be timely
converted, or that a failure to convert by another company, or a conversion that
is incompatible with the Bank's systems, would not have a material adverse
effect on the Bank. Bancorp management is engaging in due diligence to assure
that these possibilities will not occur. The Bank has determined it has no
exposure to contingencies related to the Year 2000 Issue for its products
offered to its customers.

The Bank has utilized both internal and external resources to reprogram, or
replace, and test the software for Year 2000 modifications. The Bank has already
spent $270,000 and anticipates it will spend a total of $340,000 to complete the
Year 2000 project. These costs are considered manageable by the Bank and are
being funded through operating cash flows. The costs will not have a material
effect on the results of operations in 1999 or beyond.

The time-lines and costs are based on management's best estimates, which were
derived utilizing numerous assumptions of future events, including the continued
availability of certain resources, third party modification plans and other
factors. However, there can be no guarantee that these estimates will be
achieved and actual results could differ materially from those plans. Specific
factors that might cause such material differences include, but are not limited
to, the availability and cost of personnel trained in this area, the ability to
locate and correct all relevant computer codes and similar uncertainties.

The Corporation and the Bank are aggressively addressing the Year 2000 Issue.
This issue is far-reaching in that it encompasses computer systems, microchips,
anything with time elements, and forces the Bank to ask each vendor, customer,
and third party provider if they are also ready for the millennium, which is
fast approaching.

A Senior Vice President has been given the responsibility for Y2K compliance. A
committee has been selected consisting of Board Members and Officers who have
been meeting for well over a year addressing this issue.

Letters have been sent to vendors requesting, in writing, their effort to be in
compliance with Y2K. A select group of commercial customers have been sent
letters and visited by management explaining the Y2K Issues and asking them to
be certain to address this very important issue. The Bank has also offered to
help with any questions. Notices have been placed in each Bank lobby alerting
the public to this issue. Also, verbiage has been placed on each deposit
statement concerning the Y2K Issue. Newspaper print ads and statement inserts
are planned for the last two quarters of 1999 to further communicate our
readiness to our customers.

A time-line has been created for this project. All letters were mailed by March
15, 1998 and compliance letters were received by June 30, 1998. Compliance on
all levels is very near completion. Testing will continue until the Bank is
assured all critical systems are confirmed to be Y2K compliant.

Vendors and systems have been placed in priority order as to importance. All
third party vendors that are most crucial have communicated with us stating they
are Y2K compliant and testing on their systems is complete.

Our insurance carrier has been contacted and we are working closely with it to
prudently assess the Bank's needs and take the appropriate steps to protect the
Bank.

Contingency plans have been written on any systems that do not comply or are
questionable as to their compliance.

The Bank will be diligent in its quest for assurance of compliance and will
change vendors, if necessary, to ensure a smooth change to the millennium and
continuity of banking operations and profit growth.

National bank examiners are reviewing all banks quarterly for their compliance
with these issues and the Corporation and the Bank welcome these reviews and any
assistance they will provide.
