CCFNB BANCORP, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 1998
UNAUDITED

<TABLE>
<CAPTION>
BASIS OF PRESENTATION

<S>      <C>
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 six month period ended June 30, 1998
         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; 1998 - 1,381,062
         shares and 1997 - 1,382,094 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 (including a loan impaired under
     Statement of Financial Accounting Standards No. 114) 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. Potential problem loans are identified by management as
     a part of its loan review process.

     Income recognition is in accordance with Statement of Financial Accounting
     Standards No. 118. 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.

     The Corporation adheres to principles provided by Statement of Financial
     Accounting Standards No. 114, "Accounting by Creditors for Impairment of a
     Loan", as amended by Statement of Financial Accounting Standards No. 118,
     "Accounting by Creditors for Impairment of a Loan - Income Recognition and
     Disclosure." Under these standards, the allowance for loan losses related
     to loans that are identified for evaluation in accordance with Statement
     No. 114 is based on discounted cash flows using the loan's initial
     effective interest rate or the fair value of the collateral for certain
     collateral dependent loans. Statement No. 118 allows the continued use of
     existing methods for income recognition on impaired loans and amends
     disclosure requirements to require information about the recorded
     investment in certain impaired loans and related income recognition on
     those loans. The allowance for loan losses is maintained at a level 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:

           Balance at June 30, 1998..............................   $    920
                                                                    ========
</TABLE>
     At July 24, 1998 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.


NOTE 6 - The consolidated interim financial statements have been prepared in
     accordance with requirements of Form 10-Q and therefore do not include all
     the disclosures normally required by generally accepted accounting
     principles, or those normally made in the Corporation's annual 10-K filing.
     The reader of these consolidated interim financial statements may wish to
     refer to the Corporation's annual report on Form 10-K for the period ended
     December 31, 1997, filed with the Securities and Exchange Commission.

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 increased 1.4% to $176.4 million at June 30, 1998, from $173.9
million at December 31, 1997. Net income decreased 9.1% through June 30, 1998 to
$881,000, or $.64 per share, compared to $969,000, or $.70 per share for the
same six month period ended June 30, 1997. Loans decreased in 1998 by 2.9% to
$115.5 million at June 30, 1998 from $119 million at December 31, 1997.

Results of Operations - For the Six Months Ended June 30, 1998 and June 30,
1997.

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 six months ended June 30, 1998 was $881,000, or $.64 per
share, as compared to $969,000, or $.70 per share, for the comparable period in
1997. The principal factor for the decrease was due to a 10.1% increase in
salaries and benefit expense; a 29.2% increase in furniture and equipment
expense and a 11.8% increase in other expenses offset by a net increase in
non-interest income of 34%.

Return on average assets and return on average equity were 1.00% and 7.92%,
respectively, for the six months ended June 30, 1998, as compared to 1.15% and
9.54%, respectively, for the comparable period in 1997.

Net Interest Income

For the six months ended June 30, net interest income was $3.2 million for 1998
and 1997. The net interest margin reflected a decrease to 4.10% for the six
months ended June 30, 1998 from 4.22% for the comparable period in 1997. Average
interest earning assets at June 30, 1998 increased by 3.33% over 1997.

Average loans outstanding increased from $116.4 million to $116.7 million or
 .3%, for the six months ended June 30, 1998, as compared to the six months ended
June 30, 1997. The outstanding balance of loans at June 30, 1998, decreased from
$119 million at December 31, 1997 to $115.5 million at June 30, 1998. A .4%
decrease in income on loans from $4,846 million at June 30, 1997 to $4,825
million at June 30, 1998 occurred.

Interest income from investment securities reflects a 18.2% increase comparing
$1.3 million for the six months ended June 30, 1998, and the $1.1 million for
the comparable period of 1997. The average balance of investment securities for
the six months ended June 30, 1998 increased 19.1% to $44.9 million, compared to
the $37.7 million for the same period of 1997.

Total interest expense increased $86,000 or 3.4% for the first six months of
1998, as compared to the first six months of 1997. This increase in interest
expense reflects an increase in interest cost for repurchase agreements
resulting from the 18.9% increase in the average balance of repurchase
agreements when comparing June 30, 1997 to June 30, 1998.

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
average daily balances during the indicated periods.

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 six month period ending June 30, 1998, the provision for loan losses was
$39,000, compared to the $30,000 for the corresponding period in 1997.

</TABLE>

For the six months ended June 30, 1998, total non-interest income increased
$118,000, to $465,000 compared with $347,000 for the six months ended June 30,
1997. The increase is generally the result of increases in all areas.
Specifically, the more significant increases were attributable to a surcharge
fee on non-Bank customers using the Bank's ATM's which resulted in a $25,300
increase to non-interest income. Additionally, a new fee for customers wishing
to have cancelled checks returned was introduced reflecting an increase of
$8,000.

Gross commissions earned on a result of brokerage and investment services, which
commenced in 1997, totalled $55,000 at June 30, 1998 and $0 at June 30, 1997.
The net income derived after recognition of payroll and other related expense
for this new operation was $13,000 for the first six months of 1998 and $0 for
the same period in 1997.


Non-Interest Expenses

Generally, non-interest expense accounts for the costs 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 10.1% due primarily to employee
annual increases and promotions within the Bank as well as increased costs of
employee benefit plans. Additionally, a commission relationship with brokerage
and investment service reflected costs of $29,600 for the first six months of
1998 compared to $0 for 1997. Similarly, furniture and equipment expense
increased 29.2% over 1997 for service on equipment and depreciation on newly
acquired data processing equipment. This equipment acquisition is a result of a
conversion which began in the first quarter of 1998.

CCFNB data processing is now being done in-house rather than having a third
party processor. The data processing transition will also satisfy Year 2000
compliance issues that are necessary. Improved flexibility and efficiency are
positive by-products of this conversion.

Other expenses including F.D.I.C. Insurance and State Shares Tax increased 11.8%
from $671,000 at June 30, 1997 to $750,000 at June 30, 1998 mainly due to costs
associated with the data processing conversion. Shown below is a comparison of
data processing associated other expenses for June 30, 1997 to June 30, 1998:

</TABLE>

The data processing associated expenses includes off premise posting which has
begun to decrease supplies, third pary provider buyout and legal and
professional, which consists of back-up professional services in the event of
computer failure. Although the data processing conversion will effect the profit
for 1998 it is anticipated that the savings on not having a third party provider
will offset most of these increased expenses going forward. Postage decrease is
attributable to checks no longer being returned to customers beginning in
February 1998.

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 stockholders'
equity and Tier II Capital includes the allowance for loan losses. Allowance for
loan losses must be lower than or equal to common stockholders' equity to be
eligible for Total Qualifying Capital.

</TABLE>

Management believes that the Bank's current capital position and liquidity
positions are strong and that its capital position is adequate to support its
operations.

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 with
modifications to existing software and conversions 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 could have a material
impact on the operations of the Bank.

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 will utilize both internal and external resources to reprogram, or
replace, and test the software for Year 2000 modifications. The Bank plans to
complete the Year 2000 project no later than December 31, 1998. The Bank has
already spent approximately $200,000 and anticipates it will spend $244,900 to
complete the Year 2000 project. This estimated expenditure of $244,900 is over a
three year period and includes equipment, Y2K software upgrades, technical
support and staff time. 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 1998 or beyond.

                                      -14-
<PAGE>   17


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 several months 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 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.

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. December 31,
1998 is the deadline for compliance on all levels. 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. The
third party vendors that are most crucial have communicated with us stating they
are Y2K compliant and testing on their systems is continuing.

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 discussed and will be 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 for their compliance with these
issues and the Corporation and the Bank welcome these reviews and any assistance
they will provide.
