ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS


Overview                          

        This discussion and analysis is intended to assist the reader in
understanding the financial condition and results of operations of First
National Corporation and its subsidiaries, First National Bank and National Bank
of York County. The five year period 1993 through 1997 is discussed with
particular emphasis on the years 1995, 1996 and 1997. This commentary should be
reviewed in conjunction with the financial statements and related footnotes and
the other statistical information related to First National Corporation
contained elsewhere herein, (see "Consolidated Financial Statements of First
National Corporation"). In 1995, the Corporation acquired two branches of
another commercial bank in Walterboro, South Carolina. The excess of the
purchase price over the fair value of the net tangible assets acquired was
$3,034,000. Total assets were increased by approximately $34,000,000. The
transaction was completed during the second quarter of 1995.

        In 1996, the Corporation sponsored the organization of National Bank of
York County in Rock Hill, South Carolina, and sold 170,000 shares of the
Corporation's common stock to capitalize the new bank and pay organizational and
pre-opening expenses. National Bank of York County began operations on July 11,
1996, as a wholly-owned subsidiary of the Corporation.

        In 1997, the Corporation sponsored the organization of a national bank
in Florence, South Carolina. Florence County National Bank began operations on
April 1, 1998.

Year 2000

        Many existing computer programs use only two digits to identify a year
in the data field. These Programs were designed and developed without
considering the impact of the upcoming century. If uncorrected, many computer
applications could fail or create erroneous results by or at the year 2000. The
year 2000 issue affects virtually all companies and organizations.

        Certain of the Company's systems may be affected by this so-called
millennium bug. The Company is investigating the extent to which its systems are
affected and communicating with all its computer vendors concerning timely and
completed remedies for those systems that require modification. The Company is
also communicating with all third parties on which it relies to assess their
progress in evaluating their systems and implementing any corrective measures.
The Company has been taking and will continue to pursue all reasonably necessary
steps to protect its operations and assets.

        Based upon discussions with its computer vendors and other third
parties, First National Corporation does not expect that the cost of addressing
the year 2000 issue will be a material event or certainty that would cause its
reported financial information not to be materially indicative of future
operating results or future financial conditions.

costs, and income, are subject to certain risks and uncertainties that could
cause actual results to differ materially from those indicated in the forward

others, and other risks and factors identified from time to time in First
National Corporation's reports filed with the Securities and Exchange
Commission.



Summary of Operations             

        Earnings of First National Corporation were $6,466,000, $5,528,000 and
$4,640,000 in 1997, 1996 and 1995, respectively. Net income increased 17.0
percent in 1997 when compared to 1996 and increased 19.1 percent in 1996 when
compared to 1995. Net income per share increased to $1.26 compared to $1.14 in
1996. Per share earnings in 1995 were $0.98. The increase in net income in 1997
primarily resulted from an increase in interest income as well as an increase in
noninterest income. The increase in net income in 1996 compared to 1995 also
resulted primarily from an increase in interest income as well as an increase in
noninterest income.

        The per share cash dividend declared in 1997 was $0.40 compared to $0.37
in 1996 and $0.34 in 1995.

        The book value per share of First National Corporation increased $0.91
or 9.6 percent in 1997, $1.07 or 17.7 percent in 1996, and $0.74 or 9.6 percent
in 1995. The return on average assets was 1.20 percent in 1997, 1.19 percent in
1996 and 1.13 percent in 1995. The return on average shareholders' equity was
12.72 percent for 1997 and was 12.85 percent for 1996 and 12.25 percent in 1995.

        Increases in both deposits and earning assets were realized during 1997
compared to 1996. Deposits at December 31, 1997 were $454,375,000, up
$40,222,000 or 9.7 percent, compared to December 31, 1996. At year-end 1996,
deposits were $414,153,000, up $45,838,000, or 12.4 percent, compared to
December 31, 1995. Average deposits in 1997 were $441,982,000, up $54,896,000 or
14.2 percent from 1996. The average deposits in 1996 were $387,086,000 compared
to $343,723,000 in 1995, an increase of $43,363,000 or 12.6 percent. Earning
assets reached $521,574,000, up $67,074,000, or 14.8 percent at December 31,
1997 when compared to year-end 1996. At year-end 1996, earning assets were
$454,500,000, up $55,121,000, or 13.8 percent from year-end 1995. Average
earning assets for 1997 were $503,565,000, an increase of $76,481,000, or 17.9
percent, compared to 1996. In 1996 average earning assets were $427,084,000, up
$48,608,000, or 12.8 percent, compared to 1995. The increase in earning assets
in 1997 and 1996 resulted primarily from banking operations at First National
Bank and National Bank of York County. The increases in earning assets in 1995
resulted primarily from the acquisition of two branch offices in Walterboro from
NationsBank. This transaction added approximately $34,000,000 to the deposit
base and approximately $ 15,000,000 to the loan portfolio.

        Interest income increased by $6,881,000, or 20.1 percent, for the year
ended December 31, 1997 when compared to December 31, 1996. This increase is a
result of a $67,074,000 or 14.8 percent increase in earning assets. For the year
ended December 31, 1996, interest income increased $4,080,000, or 13.5 percent,
when compared to the same period in 1995. This increase was a result of loans
and investments being repriced at higher levels due to the increase in the prime
lending rate and bond yields as well as a $55,121,000 or 13.8% increase in
earning assets.

        Interest expense increased by $ 3,379,000 or 24.2 percent, for the year
ended December 31, 1997 compared to the same period in 1996. For the year ended
December 31, 1996, interest expense increased $1,461,000 or 11.7 percent, when
compared to the same period in 1995. The 1997 increase is a direct result of a
$59,168,000 or 15.6 percent increase in interest-bearing liabilities just as the
1996 increase was a direct result of a $42,055,000 or 12.5 percent increase in
interest-bearing liabilities.

Management's Discussion And Analysis Of
Financial Condition And Results Of Operations (cont.)

Competition                    

        First National Corporation competes with a number of financial
institutions and other firms that engage in activities similar to banking. For
example, the Corporation competes for deposits with savings and loan
associations, credit unions, brokerage firms and other commercial banks. First
National continues to receive high marks from bank rating services. This has
contributed to deposit growth. In its attempt to make loans, the Corporation
competes with the industries mentioned above as well as consumer finance
companies, leasing companies and other lenders. In today's uncertain financial
climate, all lenders are searching for quality borrowers. Acquisition of
acceptable grade loans becomes more and more difficult.

        Additional financial institution mergers were completed in 1997 and
1996, continuing the trend toward consolidation. Although these mergers reduced
the number of banks and branches, the changes resulted in intensified
competition for quality funds and loans.



Net Interest Income               

        Net interest income is the difference between interest income and
interest expense. Two significant elements in analyzing a bank's net interest
income are net interest spread and net interest margin. Net interest spread is
the difference between the yield on average earning assets and the rate on
average interest-bearing liabilities. Net interest margin is the difference
between the yield on average earning assets and the rate on all average
liabilities, interest and noninterest bearing, utilized to support earning
assets. The significant distinction between spread and net interest margin is
that net interest margin reflects the volume of interest free funds supporting
earning assets.

        Net interest income increased $3,502,000 or 17.3 percent during 1997
compared to 1996. The increase was due primarily to an increase in volume of
earning assets. Net interest income increased $2,619,000 or 14.8 percent in 1996
when compared to 1995. The increase was also due primarily to increased volume
of earning assets. The average yield on earning assets was 8.2 percent in 1997
and was 8.0 percent in 1996 and 1995 respectively. Total average earning assets
increased $76,481,000, or 17.9 percent, from 1996 to 1997, and $48,608,000 or
12.8 percent, from 1995 to 1996. Total average interest bearing liabilities
increased $63,020,000, or 17.7 percent, from 1996 to 1997, and $40,196,000, or
12.7 percent, from 1995 to 1996. Growth in earning assets was funded primarily
through interest-bearing liabilities. The total volume growth in 1997 compared
to 1996 had a positive impact on net interest income of $3,718,000, which was
decreased by $216,000 due to rates paid on liabilities increasing more than
yields on assets. In 1996 compared to 1995 net interest income was positively
affected by $2,317,000 attributable to volume which was enhanced by $302,000
attributable to rate decreases. In 1997 compared to 1996, net interest spread
decreased approximately .1 percent and net interest margin remained the same. In
1996 compared to 1995, net interest spread increased approximately .1 percent
and net interest margin increased by .1 percent.

        Average noninterest-bearing funds supporting earning assets as a
percentage of earning assets changed from 13.9 percent in 1995 to 14.1 percent
in 1996 and to 13.3 percent in 1997.

Management's Discussion And Analysis Of
Financial Condition And Results Of Operations (cont.)

Investment Securities             

        Investment securities are the second largest category of earning assets.
These assets comprised 31.8 percent of earning assets at December 31, 1997 and
35.4 percent at year-end 1996. Investment securities are utilized by the
Corporation as a vehicle for the employment of excess funds, to provide
liquidity, to fund loan demand or deposit liquidation, and to pledge as
collateral for certain deposits and purchased funds.

        The portfolio taxable income was $8,637,000 in 1997 compared with
$6,908,000 in 1996, a net increase of $1,729,000. Of this increase, a gain of
approximately $1,262,000 was attributable to the $20,652,000 average volume
increase of taxable securities. The higher income generated by the increased
volume was augmented by an increase of $467,000 resulting from a 38 basis point
increase in yield. The taxable income was $6,908,000 in 1996, compared with
$6,017,000 in 1995, an increase of $891,000. Of this increase, a gain of
approximately $455,000 was attributable to the $7,958,000 average volume
increase in taxable securities. The gain generated by the increased volume was
aided by an increase of $436,000, resulting from a 38 basis point increase in
yield. This is indicative of the increases in overall interest rates in the past
year and their effect upon portfolio investments as lower-yielding securities
mature and are replaced by higher yielding investments. The average maturity of
the taxable portfolio at December 31, 1997 was 2.0 years compared with average
maturities at year-end 1996 of 2.4 years and at year-end 1995 of 2.1 years.

        The portfolio non-taxable investment income was $ 1,602,000 in 1997
compared with $1,668,000 in 1996 and $1,659,000 in 1995, a net decrease of
$66,000 or 4.0 percent, and an increase of $9,000 or 4.0 percent, respectively.
Of the decrease in 1997, a decline of $76,000 was attributable to a decrease in
average volume of $1,549,000 in municipal securities offset by an increase of
$10,000 resulting from a 3 basis point increase in yield. The increase from 1995
to 1996 was $9,000 of which $59,000 was attributable to an increase in volume
which was offset by a decrease of $ 50,000 resulting from a 15 basis point
decrease in yield. The average maturity of the non-taxable portfolio at December
31, 1997 was 3.8 years compared to 2.9 years and 2.5 years in 1996 and 1995,
respectively. First National Corporation continues to actively purchase bank
qualified tax-free securities to supplement the taxable portfolio. However, with
the negative yield adjustment due to the Tax Equity and Fiscal Responsibility
Act of 1982 and the alternative minimum tax considerations, the value to First
National Corporation of each individual purchase continues to be closely
evaluated.

        At December 31, 1997 the fair value of the securities portfolio totalled
$166,684,000, a .8 percent premium. The market valued the Corporation's 1996
portfolio at a .8 percent premium and its 1995 portfolio at a .6 percent
premium.

        SFAS No. 115, "Accounting for Certain Investments in Debt and Equity
Securities," was issued by the Financial Accounting Standards Board in May,
1993. As required, the Corporation adopted the provisions of this statement
effective December 31, 1993, without retroactive application to prior years'
financial statements. At December 31, 1997, investment securities with an
amortized cost of $114,903,000 and an estimated fair value of $115,658,000 were
classified as available-for-sale. The effect of adoption of this accounting
standard was to increase the carrying value of securities $755,000 and directly
increase shareholders' equity $476,000, net of an estimated income tax liability
of $279,000.

Investment Securities (continued)

        The increase, net of income tax effect, is presented in the statement of
changes in shareholders' equity as an adjustment of the balance of the
separate component of shareholders' equity required by SFAS No. 115 for the
unrealized holding of gains and losses on available-for-sale securities.

        On an ongoing basis, management assigns securities upon purchase into
one of the categories designated by SFAS No. 115 based on intent, taking into
consideration other factors including expectations for changes in market rates
of interest, liquidity needs, asset/liability management strategies, and capital
requirements.

        There were no realized gains or losses on sales of investment securities
during 1997. There were realized losses on sales of investment securities during
1996 of $50,000 and no realized gains or losses during 1995.

Loans                          

        Loans, net of unearned income, at December 31, 1997, were $355,513,000,
which represents an increase of $61,894,000, or 21.1 percent when compared to
year-end 1996. Average loans for 1997 increased 22.2 percent to $323,420,000
from $264,701,000 for 1996.

        The largest element of the loan portfolio continues to be the real
estate mortgage category. All loans secured by real estate, except real estate
construction, are placed in this category regardless of the loan purpose. The
use of real estate as security for loans is common in First National
Corporation's market area and this, along with other collateral, increases the
likelihood of repayment. The real estate mortgage category grew by 16.3 percent
to $207,630,000 at year-end and represents 58.4 percent of total loans. This is
a decrease from 60.8 percent in 1996. Commercial, financial and agricultural
loans increased to $67,519,000 from $46,392,000 the previous year representing
19.0 percent of the loan portfolio compared to 15.8 percent at December 31,
1996. Consumer loans represented 19.1 percent of total loans compared to 20.1
percent at year-end 1996. Table 5 provides the distribution of loans for the
past five years.

        The prime rate increased once in 1997, and the yield on the loan
portfolio for 1997 was 9.4 percent, down from 9.5 percent for 1996.
Notwithstanding this decrease in yield, the volume growth of the loan portfolio
resulted in an interest and fee income increase of $5,282,000, or 21.0 percent,
to $30,421,000. Table 6 shows the maturity and interest sensitivity of the
commercial, financial and agricultural category of the loan portfolio and the
real estate construction category of the loan portfolio as of December 31, 1997.
As of that date, loans that mature in one year or less were $83,174,000. Of the
loans that mature after one year, $183,537,000 or 75.0 percent, had fixed
interest rates while $61,315,000, or 25.0 percent, had variable rates.

        The placement of loans on a nonaccrual status is dependent upon the type
of loan, collateral values and the collection activities in progress. Loans
which are well secured and in the process of collection are allowed to remain on
an accrual basis until they become 120 days past due. Unsecured commercial loans
and well secured loans not in the process of collection are charged off on or
before the date they become 90 days past due and, therefore, do not reach a
nonaccrual status. Commercial and real estate loans which are partially secured
are written down to the collateral value and placed on nonaccrual status on or
before becoming 90 days past due. Consumer loans are charged off on or before
becoming 120 days past due. All interest accrued in the current year but unpaid
at the date a loan goes on nonaccrual status is deducted from interest income,
while interest accrued from previous years is charged against the reserve for
loan losses. At December 31, 1997, nonaccrual loans were $1,016,000 compared
with $974,000 at year-end 1996. At December 31, 1997, loans which were 90 days
or more past due were $283,000 compared to $220,000 at year-end 1996.

        During 1997, income of $54,000 on nonaccrual loans would have been
recorded if these loans had been accruing throughout 1997. No interest income on
nonaccrual loans was included in net income for 1997. First National Corporation
does not have any loans which have been restructured or any foreign loans.

        Concentrations of credit are considered to exist when the amounts loaned
to a multiple number of borrowers engaged in similar business activities which
would cause them to be similarly impacted by general economic conditions
represents 25% of equity. As of December 31,

Management's Discussion And Analysis Of
Financial Condition And Results Of Operations (cont.)

Asset Quality

        Asset quality is maintained through the management of credit risk. Each
individual earning asset, whether in the investment, loan, or short-term
investment portfolio, is reviewed by management for credit risk. To facilitate
this review, First National Corporation has established credit policies which
include credit limits, documentation, periodic examination and follow-up. In
addition, these portfolios are examined for exposure to concentration in any one
industry, government agency, or geographic location. In examining the portfolios
at December 31, 1997 and 1996, the Corporation did not have more than ten
percent of the loan portfolio in any one industry and had no foreign loans.

        Each category of earning assets has a degree of credit risk. To measure
credit risk, various techniques are utilized. Credit risk in the investment
portfolio can be measured through bond ratings published by independent
agencies. In the investment portfolio, 97.3 percent of the investments consist
of U.S. Treasury securities, U.S. Agency securities and tax-free securities
having a rating of "A" or better. The credit risk of the loan portfolio can be
measured by historical experience. The Corporation maintains its loan portfolio
in accordance with its established credit policies. Net loan charge-offs over
the past five years have not exceeded .27 percent of net average loans. In 1997
net loan charge-offs as a percentage of net average loans were .14 percent
compared to .12 percent in 1996. See "Loans" for a discussion of the Company's
charge-off and nonaccrual policies.

Management's Discussion And Analysis Of
Financial Condition And Results Of Operations (cont.)

Loan Loss Provision

        First National Corporation maintains a reserve for possible loan losses
(the allowance for loan losses) at a level which management believes is
sufficient to provide for potential losses in the loan portfolio. Management
periodically evaluates the adequacy of the allowance utilizing its internal risk
rating system and regulatory agency examinations to assess the quality of the
loan portfolio and identify problem loans. The evaluation process also includes
management's analysis of current and future economic conditions, composition of
the loan portfolio, past due and nonaccrual loans, concentrations of credit,
lending policies and procedures and historical loan loss experience. The
provision for loan losses is charged to the income statement in the amount
necessary to maintain the allowance at the appropriate level.

        The allowance is established on an overall portfolio basis, and
management does not subsequently allocate the allowance by geographic area or
loan category.

        The provision for loan losses for the year ended December 31, 1997, was
$1,251,000, compared to $1,319,000 in 1996, which represents a 5.2 percent
decrease. The decrease in the provision for loan losses was due to continued
strong loan growth.

        The allowance for loan losses was $5,518,000, or 1.55 percent of
outstanding loans at the end of 1997, and $4,705,000, or 1.60 percent at
year-end 1996. Total charge-offs were $761,000 in 1997 and $691,000 in 1996.
Recoveries were $323,000 for 1997 and $374,000 for 1996. Net charge-offs were
$438,000 in 1997 and $317,000 for 1996. Net charge-offs were greatest in
consumer loans which decreased from $399,000 in 1996 to $316,000 in 1997. Real
estate loan net charge-offs increased by $128,000 in 1997 while commercial loan
losses increased by $75,000. Net charge-offs to average loans were .14 percent
in 1997 and .12 percent in 1996. A summary of loan loss experience for 1993
through 1997 is provided in Table 8.

        Other real estate owned includes certain real estate acquired as a
result of foreclosure and deeds in lieu of foreclosure, as well as amounts
reclassified as in-substance foreclosures. For the period ended December 31,
1997, other real estate owned was $61,000 compared to $63,000 at December 31,
1996. This decrease resulted from properties being sold or written down.

        Management anticipates that the level of charge-offs for 1998 will be
somewhat higher than the level experienced in 1997. Although changes in economic
conditions in the Corporation's market area can always affect this level, the
loan loss provision is considered adequate by management.



Liquidity                      

        Liquidity is defined as the ability of an entity to generate cash to
meet its financial obligations. For a bank, liquidity means the consistent
ability to meet loan demand and deposit withdrawals. The Corporation has
employed its funds in a manner to provide liquidity in both assets and
liabilities.

        Asset liquidity is maintained by the maturity structure of loans,
investment securities and other short-term investments. Management has policies
and procedures governing the length of time to maturity on loans and
investments. As noted in Table 4, 19.0 percent of the investment portfolio
matures in one year or less. This part of the investment portfolio consists of
U.S. Treasury securities, U.S. Agency securities and bank qualified municipal
securities. Loans and other investments are of a longer term nature and are not
utilized for day-to-day bank liquidity needs.

        Increases in the Corporation's liabilities provide liquidity on a
day-to-day basis. Daily liquidity needs may be met from deposits or from the
Corporation's use of federal funds purchased, securities sold under agreements
to repurchase and other short-term borrowings at favorable interest rates.

Liquidity (continued)

        The Corporation places an increasing reliance on borrowed funds which
are primarily cash management or "sweep" accounts that are accommodations to
corporate and governmental customers pursuant to sale of securities sold under
agreement to repurchase arrangements. During 1997, the Corporation maintained an
even higher level of liquidity with an influx of interest sensitive deposits.

        In January 1997, the Securities and Exchange Commission adopted new
rules that require more comprehensive disclosure of accounting policies for
derivatives as well as enhanced quantitative and qualitative disclosures of
market risk for derivative financial instruments and other financial
instruments. The market risk disclosures must be presented for most financial
instruments, which must be classified into two portfolios: financial
instruments entered into for trading purposes and all other instruments
(non-trading purposes). The Corporation does not maintain a trading portfolio.

Management's Discussion And Analysis Of
Financial Condition And Results Of Operations (cont.)

Interest Sensitivity

        As a bank holding company, the Corporation's earnings are subject to the
risk of interest rate fluctuations. The Corporation uses a number of tools to
measure interest rate risk, including simulating the effect on earnings of
fluctuations in interest rates, monitoring the present value of asset and
liability portfolios under various interest rate scenarios and monitoring the
difference, or gap, between rate sensitive assets and liabilities, as discussed
below. The Corporation's computer model and other gap analyses take into account
the Corporation's contractual agreements with regard to investments, loans and
deposits. Although the Corporation's computer simulation model is subject to the
accuracy of the assumptions that underlie the process, the Corporation believes
that such model provides a better illustration of the interest sensitivity of
earnings than does static sensitivity gap analyses.

        The Corporation monitors exposure to a gradual increase or decrease in
rates of 200 basis points over a rolling 12-month period. The Corporation's
policy limit for the maximum negative impact on net interest income from a
gradual change in interest rates of 200 basis points over 12 months is 8%. The
Corporation generally has maintained a risk position well within the policy
guideline level. As of December 31, 1997, the model indicated that the impact of
a 200 basis point gradual increase in rates over 12 months would result in an
approximately 1.35% decrease in net interest income, while a 200 basis point
gradual decrease in rates over the same period would result in an approximately
1.14% increase from an unchanged rate environment. Actual results will differ
from simulated results due to the timing, magnitude and frequency of interest
rate changes and changes in market conditions and management strategies, among
other factors.

        Interest sensitivity analysis refers to the potential impact of interest
rate changes on net interest income. Normally this sensitivity is expressed in
interest sensitivity gap and cumulative gap. Interest sensitivity analysis
utilizes the concept of matching interest sensitive assets with interest
sensitive liabilities over a stated time period. Interest sensitivity applies to
both assets and liabilities which carry a variable rate or mature during a
stated time period. A positive interest sensitivity gap demonstrates that assets
are repriced before liabilities during the stated time period. Conversely, a
negative gap demonstrates liabilities are repriced before assets.

        The objective of interest sensitivity management is to maintain stable
growth in net interest income while minimizing adverse changes. Management is
continually changing the gap position of the Corporation in response to changes
in money markets and other external factors.


                                       20
<PAGE>   21

        Table 9 presents the interest sensitive position of the Corporation's
balance sheet at December 31, 1997. The analysis illustrates the Corporation's
interest sensitivity position at prescribed intervals. Reflected in the table
are interest sensitivity gap and cumulative gap for immediate through one year
maturities. Management particularly attempts to control gap from zero to twelve
months. The position of First National Corporation at December 31, 1997 with
regard to the cumulative gap at the 12 month time frame is a negative gap of
$13,021,000. Assuming that no other variable changed, the potential impact to
First National Corporation's net interest income before taxes in the next year
should rates on the asset and liability sides change immediately and equally
would be as follows:

                a rise of 1% would decrease earnings by $130,210

                a rise of 2% would decrease earnings by $260,420

                a rise of 3% would decrease earnings by $390,630

                a decline of 1% would increase earnings by $130,210

                a decline of 2% would increase earnings by $260,420

                a decline of 3% would increase earnings by $390,630

Table 9 reflects the balances of interest earning assets and interest-bearing
liabilities at the earlier of their repricing or maturity dates. Scheduled
payment amounts of amortizing fixed rate loans are reflected at each scheduled
payment date. Variable rate amortizing loans reflect scheduled repayments at
each scheduled payment date until the loan may be repriced contractually, and
the unamortized balance is reflected at this point. Investments are reflected at
each instrument's ultimate maturity date or pre-refunded call date. Funds sales
are reflected at the immediate repricing interval due to the overnight
availability of the instruments. A portion of interest-bearing liabilities with
no contractual maturity, such as money market deposit accounts are reflected in
the immediate repricing period due to the contractual arrangements that give
First National Corporation the ability to vary the rates paid on those deposits
within a thirty-day or shorter period. First National Corporation reflects a
portion of its savings and NOW deposits as noninterest sensitive to more
accurately reflect their anticipated repricing characteristics. Fixed rate time
deposits, principally certificates of deposit, are reflected at their
contractual maturity date.

        Variable rate time deposits are reflected at the earlier of their next
repricing or maturity date. Short-term borrowings (principally securities sold
under repurchase agreements secured by investment securities) are reflected in
the immediate repricing period due to the contractual arrangements which give
First National Corporation the ability to vary the rates paid on those
borrowings overnight.

Interest Sensitivity (continued)

        The Company does not use interest rate swaps to modify the interest rate
characteristics of certain long-term debt.

        The only derivatives the Company owns are $ 2,000,000 U.S. Government
Agency securities held as available-for-sale.


Deposits                          

        The deposit base provides First National Corporation with funds for the
long-term growth of loans and investments. At December 31, 1997, when compared
to year-end 1996, total deposits were $454,375,000, up $40,222,000, or 9.7
percent. Noninterest-bearing deposits for the same period were $70,052,000, an
increase of $2,820,000, or 4.2 percent, and interest-bearing deposits were
$384,323,000, an increase of $37,402,000, or 10.8 percent when compared to
December 31, 1996. For the year ended December 31, 1997, total average deposits
increased $54,896,000, or 14.2 percent. This growth was comprised of an increase
of average interest-bearing accounts of $47,987,000, or 14.7 percent, and
average noninterest-bearing accounts of $6,909,000, or 11.5 percent. Growth in
the interest-bearing accounts was composed of an increase in interest-bearing
transaction accounts of $3,368,000, or 4.1 percent, and certificates of deposit
of $33,575,000, or 20.2 percent, and an increase in savings accounts of
$11,044,000, or 14.2 percent.

        At December 31, 1997, the ratio of average interest-bearing deposits to
total deposits increased to 84.8 percent from 84.4 percent at year-end 1996 and
was 84.7 percent at year-end 1995. The average rate paid on interest-bearing
accounts increased to 4.1 percent from 3.9 percent at year-end 1996 and was 4.0
percent at year-end 1995.

Equity and Dividends

        Throughout the years the strength of the shareholders' equity base has
provided stability to current operations and capital adequacy to support growth.
The Corporation's shareholder equity base was 9.5 percent of total assets as of
December 31, 1997, compared with 9.7 percent at year-end 1996, and 9.1 percent
at year-end 1995.

        The Corporation has achieved a consistent record of increasing earnings
over the past years. Even though dividends have historically been increased, the
Corporation has maintained a relatively constant dividend pay-out policy. The
dividend pay-out ratio for 1997 was 31.8 percent compared to 31.1 percent in
1996 and 30.2 percent for 1995. Cash dividend payments in 1997 were $2,059,000
as compared to $1,721,000 in 1996. The retention of the remaining earnings has
provided the basis for expansion of loans and investments, and acquisitions.

        Dividends are paid by the Corporation from its assets which are mainly
provided by dividends from the Banks; however, certain restrictions exist
regarding the ability of the Banks to transfer funds to the Corporation in the
form of cash dividends, loans or advances. The approval of the Office of the
Comptroller of the Currency is required to pay dividends in excess of the Banks'
net profits for the current year plus retained net profits (net profits less
dividends paid) for the preceding two years, less any required transfers to
surplus. As of December 31, 1997, $9,466,000 of the Banks' retained earnings
were available for distribution to the Corporation as dividends without prior
regulatory approval. In 1997 the Banks paid dividends to the Corporation of
$2,054,000.

        The Corporation and subsidiaries are subject to certain risk-based
capital guidelines. These ratios measure the relationship of capital to a
combination of balance sheet and off balance sheet risks. The values of both
balance sheet and off-balance sheet items will be adjusted to reflect credit
risk. Under the guidelines of the Board of Governors of the Federal Reserve
System, which are substantially similar to the Office of the Comptroller of the
Currency guidelines, as of December 31, 1997, Tier 1 capital must be at least 4
percent of risk-weighted assets, while total capital must be 8 percent of
risk-weighted assets. The Tier 1 capital ratio for First National Corporation at
December 31, 1997 was 13.5 percent compared to 15.8 percent at year-end 1996.
The total capital ratio was 14.7 at December 31, 1997 compared to 17.1 percent
at year-end 1996.

        In conjunction with the risk-based capital ratio, applicable regulatory
agencies have also prescribed a leverage ratio of total capital to total assets
in evaluating capital strength and adequacy. The minimum leverage ratio required
for banks is between 3 percent and 5 percent, depending on the institution's
composite rating as determined by its regulators. At December 31, 1997, First
National Corporation's leverage ratio was 9.2 percent, compared to 9.5 percent
at year-end 1996. First National Corporation's ratios exceed the minimum
standards by substantial margins.

Management's Discussion And Analysis Of
Financial Condition And Results Of Operations (cont.)

Noninterest Income and Expense

        In today's banking environment, noninterest income provides a stable
source of revenue for the Corporation. The expansion of banking services and the
use of explicit pricing enables the Corporation to manage its fee income and
price services to more closely reflect actual costs. Income from noninterest
sources in 1997 was $6,259,000, an increase of $915,000, or 17.1 percent,
compared to 1996. For the period ended December 31, 1996 income from noninterest
sources was $5,344,000, an increase of $1,295,000, or 32.0 percent over 1995.

        Service charges on transaction accounts in 1997 increased $233,000 or
5.8 percent when compared to 1996 and $894,000, or 28.9 percent, in 1996
compared to 1995. This increase was due to increased account activity, as well
as an increase in service fees. The deposit fee pricing structure is continually
being reviewed and updated for new services and rising costs.

        Other charges, commissions and fees increased $682,000 or 50.3 percent
in 1997 compared to an increase of $401,000 or 42.0 percent in 1996. The
increase is a result of an increase in secondary market origination fees, ATM
surcharge fees, and alternative investment fee income.

        Noninterest expense increased $3,102,000 or 19.0 percent in 1997
compared with $2,031,000 or 14.2 percent in 1996.

<PAGE>   26

Noninterest Income and Expense (continued)

        Salary and employee benefits expense was the largest component of
noninterest expense in 1997. Salaries and employee benefits increased 16.4
percent or $1,480,000 in 1997 as compared with a 16.7 percent or $1,289,000
increase in 1996. The number of full time equivalent employees was 281 at
December 31, 1997 as compared with 281 in 1996 and 253 in 1995. The number of
full time equivalent employees remained relatively unchanged for 1996 to 1997.
The increase in 1996 as compared to 1995 was primarily the result of the
commencement of operations by the National Bank of York County. In 1994
management adopted an employee cash incentive plan covering all employees. Cash
incentives paid during 1997 under this program were $751,000.

        Net occupancy expense increased 19.8 percent in 1997 compared to an
increase of 2.9 percent in 1996. The increase is attributable to higher
operating expenses including utilities, maintenance and depreciation.

        Furniture and equipment expense increased 12.8 percent in 1997 compared
with a 26.8 percent increase in 1996. The increased costs in 1997 were due to
increases in depreciation expense and equipment service contracts.

        Total other expense for 1997 was $6,414,000 compared with $5,078,000 in
1996 and $4,710,000 in 1995, or increases of 26.3 percent and 7.8 percent
respectively. Included in other noninterest expense is $657,000 in 1997 for the
amortization of intangibles, principally core deposit values, under the purchase
accounting method utilized for bank acquisitions, compared with $644,000 in 1996
and $540,000 in 1995. Included in expenses for amortization of intangibles for
1997, is $348,000 attributable to the two branches in Walterboro acquired from
NationsBank as compared to $375,000 in 1996. Also included in other expense is
$52,000 attributed to Federal Deposit Insurance premiums, an increase of
$50,000, or 2,500.0 percent in 1997 as compared to 1996 and a decrease of
$371,000, or 99.5 percent in 1996 as compared to 1995. The decrease in the
Federal Deposit Insurance premiums in 1995 included a $201,000 refund as the
result of the Bank Insurance Fund of the FDIC reaching the 1.25 percent
capitalization level for every $100 of deposits insured by the FDIC. The
remainder of the increase in other expense for 1997 is distributed among the
following expense categories: advertising, insurance and surety bond, office and
printing supplies, postage, telephone and line charges, and other expenses.

Management's Discussion And Analysis Of
Financial Condition And Results Of Operations (cont.)

Effect of Inflation and Changing Prices

        The consolidated financial statements have been prepared in accordance
with generally accepted accounting principles which require the measure of
financial position and results of operations in terms of historical dollars,
without consideration of changes in the relative purchasing power over time due
to inflation. Unlike most other industries, virtually all of the assets and
liabilities of a financial institution are monetary in nature. As a result,
interest rates generally have a more significant effect on a financial
institution's performance than does the effect of inflation. Interest rates do
not necessarily change in the same magnitude as the prices of goods and
services.

        While the effect of inflation on banks is normally not as significant as
is its influence on those businesses which have large investments in plant and
inventories, it does have an effect. During periods of high inflation, there are
normally corresponding increases in money supply, and banks will normally
experience above average growth in assets, loans and deposits. Also, general
increases in the prices of goods and services will result in increased operating
expenses. Inflation also affects the bank's customers which may result in an
indirect effect on the banks' business.

First National Corporation



We have audited the consolidated balance sheets of First National Corporation
and Subsidiaries as of December 31, 1997 and 1996, and the related consolidated
statements of income, changes in shareholders' equity, and cash flows for each
of the years in the three-year period ended December 31, 1997. These financial
statements are the responsibility of the Corporation's management. Our
responsibility is to express an opinion on these 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 audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. The audits include examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. The audits also include
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 First National
Corporation and Subsidiaries as of December 31, 1997 and 1996, and the results
of their operations and their cash flows for each of the years m the three-year
period ended December 31, 1997, in conformity with generally accepted accounting
principles.

Notes to Consolidated Financial Statements

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES:

The accounting and reporting policies of First National Corporation (the
Corporation) and subsidiaries conform with generally accepted accounting
principles and with the prevailing practices within the banking industry. The
Company provides general banking services in the State of South Carolina.

PRINCIPLES OF CONSOLIDATION:

The consolidated financial statements include the accounts of the First National
Corporation and its wholly-owned subsidiaries, First National Bank (FNB) and
National Bank of York County (NBYC). All significant intercompany balances and
transactions have been eliminated in consolidation.

USE OF ESTIMATES:

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

INVESTMENT SECURITIES:

Debt securities that management has the ability and intent to hold to maturity
are classified as held-to-maturity and carried at cost, adjusted for
amortization of premium and accretion of discounts using methods approximating
the interest method. Other marketable securities are classified as
available-for-sale and are carried at fair value. Securities available-for-sale
also include the required capital stock of the Federal Reserve Bank. Unrealized
gains and losses on securities available-for-sale are recognized as direct
increases or decreases in shareholders' equity. Cost of securities sold is
recognized using the specific identification method.

LOANS AND ALLOWANCE FOR LOAN LOSSES:

Loans are stated at the amount of unpaid principal, reduced by unearned discount
and an allowance for loan losses. Unearned discount on installment loans is
recognized as income over the terms of the loans by methods which generally
approximate the interest method. Interest on other loans is calculated by using
the simple interest method on daily balances of the principal amount
outstanding. Loans are placed on nonaccrual when a loan is specifically
determined to be impaired or when principal or interest is delinquent for 120
days or more. A nonaccrual loan may not be considered impaired if it is expected
that the delay in payment is minimal. When interest accrual is discontinued, all
unpaid accrued interest is reversed. Interest income is subsequently recognized
only to the extent cash payments are received.

Notes to Consolidated Financial Statements (Cont.)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES (CONTINUED):

The allowance for loan losses is established through a provision for loan losses
charged to expenses. Loans are charged against the allowance for loan losses
when management believes that the collectibility of the principal is unlikely.
The allowance is an amount that management believes will be adequate to absorb
possible losses on existing loans that may become uncollectible, based on
evaluations of the collectibility of loans and prior loan loss experience. The
evaluations take into consideration such factors as changes in the nature and
volume of the loan portfolio, overall portfolio quality, review of specific
problem loans and current economic conditions that may affect the borrowers'
ability to pay. An allowance for impaired loans is generally determined based on
collateral values or the present value of estimated cash flows. The allowance is
increased by a provision for loan losses, which is charged to expense, and
reduced by charge-offs, net of recoveries.

For impairment recognized in accordance with Statement of Financial Accounting
Standards No. 114 (SFAS 114), Accounting by Creditors for Impairment of a Loan,
the entire change in present value of expected cash flows is reported as bad
debt expense in the same manner in which impairment initially was recognized or
as a reduction in the amount of bad debt expense that otherwise would be
reported.

OTHER REAL ESTATE OWNED (OREO):

Real estate acquired in satisfaction of a loan and in-substance foreclosures are
reported in other assets. In-substance foreclosures are properties in which the
borrower has little or no equity in the collateral. Properties acquired by
foreclosure or deed in lieu of foreclosure and in-substance foreclosures are
transferred to OREO and recorded at the lower of the outstanding loan balance at
the time of acquisition or the estimated market value. Market value is
determined on the basis of the properties being disposed of in the normal course
of business and not on a liquidation or distress basis. Loan losses arising from
the acquisition of such properties are charged against the allowance for loan
losses. Gains or losses arising from the sale of OREO are reflected in current
operations.

PREMISES AND EQUIPMENT:

Office equipment, furnishings, and buildings are stated at cost less accumulated
depreciation computed principally on the declining-balance method over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the estimated useful lives of the
improvements or the terms of the related leases. Additions to premises and
equipment and major replacements are added to the accounts at cost. Maintenance
and repairs and minor replacements are charged to expense when incurred. Gains
and losses on routine dispositions are reflected in current operations.

INTANGIBLE ASSETS:

Intangible assets consist primarily of core deposit premium costs which resulted
from the acquisition of branches from other commercial banks. The excess of the
purchase price over the fair value of the net tangible assets acquired in the
transactions is included in other assets and is being amortized over the
estimated useful lives of the deposit accounts acquired on a method which
reasonably approximates the anticipated benefit stream from the accounts. (SEE
NOTE 7.)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES (CONTINUED):

EMPLOYEE BENEFIT PLANS:

Pension Plan - The Corporation and its subsidiaries have a non-contributory
defined benefit pension plan covering all employees who have attained age
twenty-one and have completed one year of eligible service. The Company's
funding policy is to contribute annually the amount necessary to satisfy the
Internal Revenue Service's funding standards.

Profit Sharing Plan - The Corporation and its subsidiaries have a profit-sharing
plan, including Internal Revenue Code Section 401(k) provisions. Electing
employees are eligible to participate after attaining age twenty-one and
completing one year of eligible service. Plan participants elect to contribute
1% to 4% of annual base compensation as a before tax contribution. The Company
matches 50% of these contributions. Employer contributions may be made from
current or accumulated net profits. Participants may additionally elect to
contribute 1% to 6% of annual base compensation as a before tax contribution
with no employer matching contribution.

Retiree Medical Plan - Post-retirement health and life insurance benefits are
provided to eligible employees which is limited to those employees of the
Corporation eligible for early retirement under the pension plan on or before
December 31, 1993, and former employees who are currently receiving benefits.
The plan was unfunded at December 31, 1997, and the liability for future
benefits has been recorded in the consolidated financial statements.

LEASE COMMITMENTS:

The Corporation's subsidiaries have entered into a number of operating lease
agreements for land and buildings used in operations. The agreements expire over
various terms with the longest such term extending to the year 2002. Certain of
the leases contain renewal options. In addition, the subsidiaries pay
maintenance, property taxes and insurance on certain of the leased properties.

CASH AND CASH EQUIVALENTS:

For the purposes of presentation in the consolidated statements of cash flows,
cash and cash equivalents are defined as those amounts included in the balance
sheet caption "Cash and due from banks". These amounts include cash on hand,
cash items in process of collection, and amounts due from banks. Due from bank
balances are maintained in other financial institutions.

INCOME TAXES:

The Company is subject to federal and state income taxes. Deferred income tax
assets and liabilities are computed annually for differences between the
financial statement and tax basis of assets and liabilities that will result in
taxable or deductible amounts in the future based on enacted tax laws and rates
applicable to the periods in which the differences are expected to be realized.
Income tax expense is the tax payable or refundable for the period plus or minus
the change during the period in deferred tax assets and liabilities.

ADVERTISING COSTS:

The Company expenses the cost of advertising as incurred.

OTHER:

Certain amounts previously reported have been restated in order to conform with
current year presentation. Such reclassifications had no effect on net income.

NOTE 2 - FORMATION OF BANKING SUBSIDIARIES:

NATIONAL BANK OF YORK COUNTY:

The National Bank of York County commenced business operations as a national
bank in Rock Hill, South Carolina, on July 11, 1996. The National Bank of York
County is also a full service commercial bank and its deposits are insured to
applicable limits by the Federal Deposit Insurance Corporation (FDIC). Upon
completion of its organization, 100% of the common stock of the National Bank of
York County was acquired by First National Corporation, and the bank operates as
a wholly owned subsidiary of the Corporation with its own Board of Directors and
operating policies.

FLORENCE COUNTY NATIONAL BANK:

The Corporation is sponsoring the organization of a national bank in Florence,
South Carolina. The organizers have filed an application with the Office of the
Comptroller of the Currency and the Federal Deposit Insurance Corporation,
respectively, for a charter to form the Florence County National Bank and for
insurance of deposits. The Corporation has also filed applications with the
Board of Governors of the Federal Reserve System and the South Carolina State
Board of Financial Institutions to acquire all of the bank's stock upon
completion of its organization, so that the newly formed bank will be a
wholly-owned subsidiary of the Corporation. Florence County National Bank (In
Organization) is expected to begin operations during 1998.

NOTE 3 - RESTRICTIONS ON CASH AND DUE FROM BANK ACCOUNTS:

As a members of the Federal Reserve System, the Corporation's banking
subsidiaries are required by regulation to maintain an average cash reserve
balance with the Federal Reserve Bank. The average amount of such reserve
balance as of December 31, 1997, was approximately $4,309,000.

At December 31, 1997, the Corporation and its subsidiaries had due from bank
balances in excess of federally insured limits in the amount of $769,000. The
risks associated with this excess is limited due to the soundness of the
financial institutions with which the funds are deposited.

NOTE 5 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED):

The Corporation's banking subsidiaries grant agribusiness, commercial, and
residential loans to customers throughout the state. Although the subsidiaries
have a diversified loan portfolio, a substantial portion of their debtors'
ability to honor their contracts is dependent upon the economy of Orangeburg
County, York County, and other surrounding areas.

The Company determines when loans become impaired through its normal loan
administration and review functions. Those loans identified as substandard or
doubtful as a result of the loan review process are potentially impaired loans.
A loan is impaired when, based on current information and events, it is probable
that a creditor will be unable to collect all principal and interest amounts due
according to the contractual terms of the loan agreement. A loan is not impaired
during a period of delay in payment if the Company expects to collect all
amounts due, including interest accrued at the contractual interest rate, for
the period of delay.

In accordance with these standards, the Company does not apply SFAS 114 and SFAS
118 to large groups of smaller-balance homogeneous loans that are collectively
evaluated for impairment. These groups include the banking subsidiaries' credit
card, residential mortgage, overdraft protection, home equity lines, accounts
receivable financing, and consumer installment loans.

There were no impaired loans at December 31, 1997 and 1996.

Under guidelines established by the Company, concentrations of credit are
considered to exist when the amounts loaned to a multiple number of borrowers
engaged in similar business activities which would cause them to be similarly
impacted by general economic conditions represents 25% of equity. There were no
concentrations of credit at December 31, 1997.

Depreciation expense charged to operations was $1,177,000, $1,020,000, and
$891,000 in 1997, 1996, and 1995, respectively.

NOTE 7 - INTANGIBLE ASSETS:

Core deposit premium cost in the original amount of $1,822,000, which resulted
from the purchase of two branches of another commercial bank, is being amortized
on the straight-line basis over the estimated useful lives of the deposit
accounts acquired, which range from two to fourteen years. The acquisition cost
was allocated to the assets acquired based on their fair market value.
Amortization expense, which is included in other non-interest expense, for the
years ended December 31, 1997, 1996, and 1995, was $34,000, $80,000, and
$120,000, respectively.

On July 1, 1991, FNB completed the purchase of a branch of another commercial
bank. The excess of the purchase price over the fair value of the net tangible
assets acquired has been recorded as core deposit premium cost in the amount of
$1,124,000, and is being amortized over ten years on a method which reasonably
approximates the anticipated benefit stream from the related deposit accounts.
Amortization expense for the years ended December 31, 1997, 1996, and 1995, was
$98,000, $110,000, and $122,000, respectively.

On June 16, 1995, FNB completed the purchase of two branches of another
commercial bank. The excess of the purchase price over the fair value of the net
tangible assets acquired has been recorded as core deposit premium cost in the
amount of $3,034,000, and is being amortized over fifteen years on a method
which reasonably approximates the anticipated benefit stream from the related
deposit accounts. Amortization expense for the year ended December 31, 1997,
1996, and 1995, was $348,000, $375,000 and $231,000, respectively.

Computer software (acquired by purchase) with an original cost of $1,068,000 is
being amortized on the straight-line method over thirty-six months. Amortization
expense was $177,000, $75,000, and $66,000, for the years ended December 31,
1997, 1996, and 1995, respectively.

NOTE 8 - IMPAIRMENT OF LONG-LIVED ASSETS AND CERTAIN IDENTIFIABLE INTANGIBLES:

In March, 1995, the Financing Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121 (SFAS 121), Accounting for the Impairment
of Long-lived Assets and for Long-lived Assets to be Disposed Of, effective for
fiscal years beginning after December 15, 1995. This statement requires that
long-lived assets and certain identifiable intangibles to be held and used by an
entity to be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. If the
total of the expected future cash flows expected to result from the use of the
asset and its eventual disposition is less than the carrying amount of the
assets, an impairment loss is recognized. Impairment losses resulting from the
application of this statement should be reported in the period in which the
recognition criteria are first applied and met. The initial application of SFAS
121 is to be reported as the cumulative effect of a change in accounting
principle. As of December 31, 1997, the Corporation and its banking subsidiaries
did not hold any long-lived assets or intangibles which have to be considered
impaired as a result of the application of SFAS 121.

NOTE 9 - DEPOSITS:

The aggregate amount of jumbo certificates of deposit, each with a minimum
denomination of $100,000 was approximately $40,795,000 and $38,616,000 at
December 31, 1997 and 1996, respectively.

At December 31, 1997, the scheduled maturities of certificates of deposit are as

NOTE 13 - COMMON STOCK AND PER SHARE INFORMATION:

In 1997, the Financial Accounting Standards Board issued SFAS No. 128,
"Earnings Per Share", which establishes standards for computing and presenting
earnings per share ("EPS") by replacing the presentation of primary EPS with a
presentation of basic EPS. In addition, SFAS No. 128 requires dual presentation
of basic and diluted EPS on the face of the income statement and requires a
reconciliation of the numerator and denominator of the diluted EPS calculation.
The Corporation has adopted SFAS No. 128 as of December 31, 1997.

In accordance with SFAS 128, the calculation of basic net income per share and
diluted net income per share is presented below:

Corporation shares outstanding.


NOTE 14 - RESTRICTIONS ON SUBSIDIARY DIVIDENDS, LOANS OR ADVANCES:

Dividends are paid by the Corporation from its assets which are mainly provided
by dividends from the banking subsidiaries. However, certain restrictions exist
regarding the ability of the subsidiaries to transfer funds to the Corporation
in the form of cash dividends, loans or advances. The approval of the Office of
the Comptroller of the Currency (OCC) is required to pay dividends in excess of
the subsidiaries' net profits for the current year plus retained net profits
(net profits less dividends paid) for the preceding two years, less any required
transfers to surplus. As of December 31, 1997, $9,466,000 of FNB's retained
earnings are available for distribution to the Corporation as dividends without
prior regulatory approval.

Under Federal Reserve regulation, the banking subsidiaries are also limited as
to the amount they may loan to the Corporation unless such loans are
collateralized by specified obligations. The maximum amount available for
transfer from FNB and NBYC to the Corporation in the form of loans or advances
approximated $9,146,000 and $798,000, respectively, at December 31, 1997.

NOTE 16 - POST-RETIREMENT BENEFITS (CONTINUED):

The weighted-average discount rate used in determining the accumulated
post-retirement benefit obligation was 7.5%. For measurement purposes, a 13%
annual rate of increase in the per capita cost of covered health care benefits
was assumed for 1993; the rate was assumed to decrease by 1% per year to 6% at
the end of seven years. Increasing the assumed health care cost trend rates by 1
percentage point in each year would increase the accumulated post retirement
benefit obligation as of December 31, 1997 by $48,000 and the aggregate of the
service and interest cost components of net periodic post-retirement benefit
cost for the year then ended by $4,000.

NOTE 17 - STOCK-BASED COMPENSATION PLANS:

The Corporation has reserved 133,402 shares of common stock for issuance to key
employees under the Incentive Stock Option Plan of 1992 and an additional
153,300 shares of common stock for issuance to key employees under the 1996
Incentive Stock Option Plan. Options under both plans may not be exercised in
whole or in part within one year following the date of the grant of the options,
and thereafter become exercisable in 25% increments over the next four years.
The exercise price of the options may not be less than fair market value of the
common stock on the date of the grant. No options may be exercised after five
years from the date of the grant. No option shall be granted under the 1992 plan
after March 12, 1997, at which time the plan terminated. Options granted before
such date may extend beyond that date in accordance with the Plan.

Activity in both stock option plans is summarized below. All information has
been retroactively restated to reflect stock dividends and stock splits.

The Corporation has entered into a Restricted Stock Agreement with the chief
executive officer. The agreement grants to the employee 10,888 shares of
restricted common stock conditioned upon continued employment. The options vest
free of restrictions as follows: 25% in 1999, 25% in 2001, and 50% in 2003.
Termination of employment prior to a vesting date would terminate any interest
in non-vested shares. Prior to vesting of the shares, as long as employed as
chief executive officer, the employee will have the right to vote such shares
and to receive dividends paid with respect to such shares. All restricted shares
will fully vest in the event of change of control of the Corporation or upon the
death of the employee. The weighted average fair value of the shares granted
under this agreement is $6.34.

The fair value of the options granted and the stock issued was estimated on the
date of the grant using the Black-Scholes option pricing model with the
following assumptions: risk-free interest rate of 6.125%, dividend yield of
2.7%, expected life of options of 5 years, expected life of restricted stock of
7 years, and volatility of 7.85%.

NOTE 17 - STOCK OPTION PLAN (CONTINUED):

The Corporation currently accounts for its stock-based compensation plans using
the provisions of Accounting Principles Board Opinion No. 25, Accounting for
Stock Issued to Employees (APB 25). In 1995, the FASB issued Statement of
Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation
(SFAS 123) effective for transactions entered into after December 15, 1995.
Under the provisions of SFAS 123, companies can elect to account for stock-based
compensation plans using a fair-value-based method or continue measuring
compensation expense for those plans using the intrinsic value method prescribed
in APB 25. Had compensation cost for the 1996 stock option plan been determined
based on the fair value at the grant dates for awards under the plan consistent
with the method of SFAS 123, the Corporation's net income and earnings per share
would have been reduced to the pro forma amounts indicated below:

NOTE 18- LONG-TERM LEASES:

The Corporation's banking subsidiaries were obligated at December 31, 1997,
under certain operating leases extending to the year 2002 for land and buildings
used primarily for banking purposes. Some of the leases provide for the payment
of property taxes and insurance and contain various renewal options. The
exercise of renewal options is, of course, dependent upon future events.
Accordingly, the following summary does not reflect possible additional payments
due if renewal options are exercised.

NOTE 19 - COMMITMENTS AND CONTINGENT LIABILITIES:

The Corporation and its banking subsidiaries are involved at times in various
litigation arising out of the normal course of business. In the opinion of the
Company's legal counsel, there is no pending or threatened litigation of any
material consequence at this time.

The Corporation has entered into a $4,500,000 unsecured line of credit from an
unaffiliated bank. There were no borrowings outstanding at December 31, 1997.

NOTE 20 - RELATED PARTY TRANSACTIONS:

During 1997 and 1996, the Corporation's banking subsidiaries had loan and
deposit relationships with certain related parties; principally, directors and
executive officers, their immediate families and their business interests. All
of these relationships were in the ordinary course of business. Total loans
outstanding to this group (including immediate families and business interests)
amounted to $8,025,000 at December 31, 1997, and $8,970,000 at December 31,
1996. During 1997, $15,535,000 of new loans were made to this group. Repayments
of $15,677,000 were made during the year. Other changes, which included loans
outstanding to new or former officers and directors, resulted in a decrease of
$803,000.

NOTE 21 - FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK:

The Corporation's banking subsidiaries are parties to financial instruments with
off-balance sheet risks in the normal course of business to meet the financing
needs of its customers. These financial instruments include commitments to
extend credit, standby letters of credit and financial guarantees. These
instruments involve, to varying degrees, elements of credit, interest rate, or
liquidity risk in excess of the amounts recognized in the balance sheet. The
contract amounts of these instruments express the extent of involvement the
banks have in particular classes of financial instruments.

The subsidiaries' exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for commitments to extend credit,
standby letters of credit and financial guarantees written is represented by the
contractual amount of those instruments. The subsidiaries use the same credit
policies in making commitments and conditional obligations as they do for
on-balance sheet instruments.

NOTE 21 - FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK (continued)

COMMITMENTS TO EXTEND CREDIT:

These are legally binding agreements to lend to a customer. Commitments
generally have fixed expiration dates or other termination clauses and may
require payment of a fee. Since many of the commitments are expected to expire
without being drawn upon, the total commitment amounts do not necessarily
represent future liquidity requirements. The banking subsidiaries evaluate each
customer's credit worthiness on a case-by-case basis. The amount of collateral
obtained, if deemed necessary by the subsidiaries upon extension of credit, is
based on management's credit assessment of the counter party. Collateral held
varies but may include accounts receivable, inventory, property, plant and
equipment, and personal guarantees.

STANDBY LETTERS OF CREDIT AND FINANCIAL GUARANTEES WRITTEN:

These instruments are conditional commitments issued by the banking subsidiaries
guaranteeing the performance of a customer to a third party. Those guarantees
are primarily issued to support public and private borrowing arrangements. All
standby letters of credit outstanding at December 31, 1997, expire in 1998. The
credit risk involved in issuing a letter of credit is essentially the same as
that involved in extending loan facilities to customers. The amount of
collateral obtained, if deemed necessary, is based on management's credit
evaluation of the customer.

NOTE 22 - DERIVATIVE FINANCIAL INSTRUMENTS:

In accordance with established policy, the Corporation and its banking
subsidiaries hold derivative financial instruments which meet the following
criteria: (1) government agency security, (2) five years or less in maturity,
(3) readily identifiable indexes, and (4) "conservative" investment. The total
amount of the investment in structured notes, as a percentage of capital, has
been set by policy not to exceed 61 percent. The Company no longer purchases
structured notes.

The financial derivatives held by the Company as of December 31, 1997 and 1996,
consist of structured notes which meet the above criteria. The purpose of such
holdings include the ability to take advantage of enhanced basis point yield
spread and to take advantage of variable rate products to facilitate in the
management of the gap ratio. All such investments are classified as
available-for-sale and, therefore, recorded at fair value in the financial
statements. During the year ended December 31, 1996, derivative financial
instruments were sold and a loss of $50,000 reported. No gains or losses were
reported in the income statements from these holdings in 1997 and 1995.

As of December 31, 1997 and 1996, the Corporation and its subsidiaries held
derivative financial instruments in the amount of $2,000,000 and $7,999,000.

NOTE 23 - FAIR VALUE OF FINANCIAL INSTRUMENTS:

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate that
value:

INVESTMENT SECURITIES:

For securities held as investments, fair value equals quoted market price, if
available. If a quoted price is not available, fair value is estimated using
quoted market prices for similar securities.

LOANS RECEIVABLES:

The fair value of loans is estimated by discounting the future cash flows using
the current rates at which similar loans would be made to borrowers with similar
credit ratings and for the same remaining maturities.

DEPOSIT LIABILITIES:

The fair value of demand deposits, savings accounts, and certain money market
deposits is the amount payable on demand at the reporting date. The fair value
of fixed-maturity certificates of deposit is estimated using the rates currently
offered for deposits of similar remaining maturities.

FEDERAL FUNDS PURCHASED:

The fair value of federal funds purchased is estimated based on the current
rates offered for borrowings of the same remaining maturities.

COMMITMENTS TO EXTEND CREDIT, STANDBY LETTERS OF CREDIT AND FINANCIAL
GUARANTEES WRITTEN:

The fair value of commitments 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 counter parties. For fixed
rate loan commitments, fair value also considers the difference between current
levels of interest rates and the committed rates. The fair value of guarantees
and letters of credit is based on fees currently charged for similar agreements
or on the estimated cost to terminate them or otherwise settle the obligations
with the counter parties at the reporting date.

NOTE 24 - REGULATORY MATTERS

The Corporation and its banking subsidiaries are subject to various regulatory
capital requirements administered by the federal banking agencies. Failure to
meet minimum capital requirements can initiate certain mandatory and possibly
additional discretionary - actions by regulators that, if undertaken, could have
a direct material effect on the financial statements. Under capital adequacy
guidelines and the regulatory framework for prompt corrective action, the
Corporation and its subsidiaries must meet specific capital guidelines that
involve quantitative measures of the assets, liabilities, and certain
off-balance-sheet items as calculated under regulatory accounting practices. The
capital amounts and classification are also subject to qualitative judgments by
the regulators about components, risk weightings, and other factors.

Notes to Consolidated Financial Statements (Cont.)

NOTE 24 - REGULATORY MATTERS (CONTINUED)

Quantitative measures established by regulation to ensure capital adequacy
require the Corporation and its subsidiaries to maintain minimum amounts and
ratios (set forth in the table below) of total and Tier I capital (as defined in
the regulations) to risk-weighted assets (as defined), and of Tier I Capital (as
defined) to average assets (as defined). Management believes, as of December 31,
1997, that the Corporation and its subsidiaries meet all capital adequacy
requirements to which they are subject.

As of December 31, 1997, the most recent notification from the Office of the
Comptroller of the Currency categorized the Corporation and its subsidiaries as
well capitalized under the regulatory framework for prompt corrective action. To
be categorized as well capitalized, the entities must maintain minimum total
risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the
table. There are no conditions or events since that notification that management
believes have changed the institutions' category.

Actual capital amounts and ratios are also presented in the table.
