MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

FORWARD LOOKING STATEMENT

The Private Securities Litigation Act of 1995 contains safe harbor provisions
regarding forward looking statements. When used in this discussion, the words
"believes," "anticipates," "contemplates," "expects," and similar expressions
are intended to identify forward-looking statements. Such statements are subject
to certain risks and uncertainties that could cause actual results to differ
materially from those projected. Those risks and uncertainties include changes
in interest rates, the ability to control costs and expenses, and general

COMPARISON OF THE THREE MONTHS ENDED SEPTEMBER 30, 2000 AND 1999

Total interest income of $5,243,000 for the three- month period ended September
30, 2000 compared to $4,217,000 for the same three-month period in 1999, an
increase of $1,026,000 or 24.3%. The overall increase in total interest income
is attributed to an increase in interest and fees on loans of $1,062,000 or
28.3%. Income from interest and fees on loans increased due to volume increases
within the loan portfolio. Average loans, including loans available for sale, at
September 30, 2000 were $216.7 million, an increase of $38.9 million or 21.9%
from $177.8 million at September 30, 1999.

Although virtually all segments within the loan portfolio reflected net
increases in average balances, the most significant growth occurred within the
1-4 family real estate and commercial real estate segments. Average 1-4 family
real estate loans increased $18.0 million or 23.5%, average commercial real
estate loans increased $14.8 million or 30.5%, and consumer loans increased $8.2
million or 40.1%. These increases were partially offset by a decline in student
loans of $6.9 million, as a result of those loans being sold. Although
management continues to pursue new lending opportunities, the increase within
the loan portfolio was brought about by general market activity.

Total interest expense of $2,402,000 for the three-month period ended September
30, 2000 represented an increase of $722,000 from the $1,680,000 reported for
the same three-month period in 1999. The increase in interest expense was
comprised of increases in interest expense on deposits of $331,000 and on
borrowed funds of $391,000. The increase in interest on both deposits and
borrowed funds was due to an increase in average borrowings outstanding during
the three-month period ended September 30, 2000. Average deposits increased
$12.8 million and average borrowed funds increased $22.5 million compared to the
same period in 1999. The advances are used for general liquidity purposes and to
meet the demands of the current lending opportunities.

Net interest income of $2,841,000 for the three months ended September 30, 2000
compared to $2,537,000 for the same three-month period in 1999, an increase of
$304,000.

The provision for loan losses amounted to $173,000 an increase of $68,000
compared to the same period in 1999. The increased level of provision for loan
losses was primarily fueled by the loan growth during 2000 combined with
management's continual evaluation of the adequacy of the allowance for loan
losses. On a quarterly basis, the allowance for loan losses is evaluated based
upon local economic conditions, performance of outstanding loans, an
individual's ability to repay based on an evaluation of a borrower's financial
condition and performance, trends within the loan portfolio such as growth,
delinquencies, and charge-off activity, and trends within the industry.

Total other income for the three-month period ended September 30, 2000 of
$453,000 compared to $361,000 for the three-month period ended September 30,
1999, an increase of $92,000. An increase in service charges on deposit accounts
of $40,000 and an increase in gains on the sale of loans of $31,000 account for
this increase. The increase in service charges on deposit accounts increased due
to volume activity and to price restructurings during third quarter 1999.

Total other expense of $1,908,000 for the three-months ended September 30, 2000
compared to $1,550,000 for the same three-month period in 1999. This represented
an increase of $358,000 or 23.1%. The increase is primarily derived from an
increase in salaries and employee benefits expense of $94,000, and an increase
stationary, printing, and supplies of $37,000. The increase in salary and
benefits is attributed to staff additions pertaining to the Lawrence County,
Pennsylvania expansions. The New Wilmington, Pennsylvania branch office
celebrated its "Grand Opening" on March 10, 2000. The Company anticipates
opening its Laurel Office in Hickory Township, Lawrence County during the first
quarter of 2001. In addition, the Company will open its new supermarket branch
in Slippery Rock on October 20, 2000.

Net income for the three-month period ended September 30, 2000 was $857,000, a
decrease of $25,000 from the $882,000 reported at September 30, 1999. Earnings
per share for the three-month period ended September 30, 2000 was $0.31, a
decrease of $0.01 from $0.32 per share earned during the same three-month period
in 1999.


COMPARISON OF THE NINE MONTHS ENDED SEPTEMBER 30, 2000 AND 1999

Total interest income of $14,506,000 for the nine-month period ended September
30, 2000 compared to $12,348,000 for the same nine-month period in 1999, an
increase of $2,158,000 or 17.5%. The primary increase in total interest income
is attributed to an increase in interest and fees on loans of $2,400,000 or
22.1%. Income from interest and fees on loans increased due to volume increases
within the loan portfolio, as discussed above.

Total interest expense of $6,290,000 for the nine-month period ended September
30, 2000 represented an increase of $1,226,000 from the $5,064,000 reported for
the same nine-month period in 1999. The increase in interest expense was
comprised of increases in interest expense on deposits of $442,000 and on
borrowed funds of $784,000. The increase in interest on both deposits and
borrowed funds was due to an increase in average borrowings outstanding during
the nine-month period ended September 30, 2000.

Net interest income of $8,216,000 for the nine months ended September 30, 2000
compared to $7,284,000 for the same nine-month period in 1999, an increase of
$932,000.

Total other income for the nine-month period ended September 30, 2000 of
$1,343,000 compared to $1,171,000 for the nine-month period ended September 30,
1999, an increase of $172,000. Increases in service charges on deposit accounts
of $166,000 and other income of $75,000 were partially offset by a decline of
$64,000 in gains on the sale of loans. The increase in service charges on
deposit accounts increased due to volume activity and to price restructurings
during third quarter 1999. The increase in "other" miscellaneous income was due
to three items; an increase in insurance commissions, an increase in debit card
interchange fees, and an increase in trust brokerage commission fees. Insurance
commissions increased $43,000 resulting from the sale of life and accident and
health insurance on new loan originations. Debit card interchange fees, which
are fees paid by merchants that accept debit cards for purchases, increased
$40,000 due to increased activity. Trust brokerage commissions increased $11,000
due to increased sales of non-traditional deposit products within the Bank's
Trust Division.

Total other expense of $5,358,000 for the nine-months ended September 30, 2000
compared to $4,792,000 for the same nine-month period in 1999. This represented
an increase of $566,000 or 11.8%. The increase is primarily derived from an
increase in salaries and employee benefits expense of $249,000, and an increase
stationary, printing, and supplies of $68,000. The increase in salary and
benefits is attributed to staff additions pertaining to the Lawrence County,
Pennsylvania expansions.

Net income for the nine-month period ended September 30, 2000 was $2,688,000, an
increase of $315,000 from the $2,373,000 reported at September 30, 1999.
Earnings per share for the nine-month period ended September 30, 2000 was $0.97,
an increase of $0.11 from $0.86 per share earned during the same nine-month
period in 1999.

FINANCIAL CONDITION

Total assets increased $41.8 million or 17.9% from $233.0 million at December
31, 1999 to $274.8 million at September 30, 2000. The increase in total assets
is due primarily to an increase in total loans, including loans available for
sale, of $40.2 million. The most significant growth occurred within the 1-4
family real estate portfolio, which increased $15.1 million. This was followed
by net increases within the consumer, commercial and commercial real estate
portfolios of $7.6 million, $4.6 million and $9.3 million, respectively.

Total deposits of $220.2 million at September 30, 2000 represented an increase
of $23.1 million or 11.7% from $197.1 million at December 31, 1999. With the
exception of money market deposit accounts, all deposit products had net
increases during the period. The most significant increases were within time
certificates, savings, and non-interest bearing demand, which increased $14.2
million, $5.8 million and $4.6 million, respectively. The increases were due to
the opening of the New Wilmington branch facility and to various time
certificate promotions as part of the "Grand Opening". The decrease in money
market accounts is attributed to seasonal activity of the local university.

At September 30, 2000, the Company serviced approximately $46.1 million in sold
fixed rate mortgages. Sales of fixed rate mortgages for the period ended
September 30, 2000 totaled $5.8 million with net gains of $59,000. Management
does anticipate future sales of fixed rate mortgages; however, the extent to
which the Company participates in the secondary market will be dependent upon
demand for fixed rate mortgages in the market place, liquidity needs of the
Company and interest rate risk exposure. Management will continue to obtain the
necessary documentation to allow loans to be sold in the secondary market, so
that if liquidity or market conditions dictate, management will be able to
respond to these conditions.

At September 30, 2000, management has calculated and monitored risk-based and
leverage capital ratios in order to assess compliance with regulatory
guidelines. The following schedule presents certain regulatory capital ratio
requirements along with the Company's position at September 30, 2000:

<TABLE>
<CAPTION>

Tier 1 risk - based capital                       $ 26,518          12.99%          4.00%          6.00%

Total risk - based capital                          28,441          13.93           8.00          10.00

Leverage capital                                    26,518           9.95           4.00           5.00
</TABLE>

As the above table illustrates, the Company exceeds both the minimum and "well
capitalized" regulatory capital requirements at September 30, 2000. Management
does not anticipate any future activity that would have a negative impact on any
of these ratios. Also, management is not aware of any current recommendations by
the regulatory agencies that will have a material effect on future earnings,
liquidity or capital of the Company.

LIQUIDITY

The principal functions of the Company's asset/liability management program are
to provide adequate liquidity and to monitor interest rate sensitivity.
Liquidity represents the ability to meet the cash flow requirements of both
depositors and customers requesting bank credit. Asset liquidity is provided by
repayments and the management of maturity distributions for loans and
securities. An important aspect of asset liquidity lies in maintaining adequate
levels of adjustable rate, short term, or relatively risk free interest earning
assets. One measure that the Company uses to monitor liquidity is the liquidity
ratio, which assesses the relationship between certain earning assets, customer
deposits and short-term interest bearing liabilities. This ratio was 3.1% of
total assets as of September 30, 2000 compared to 2.6% at December 31, 1999.
Management views this ratio to be at an adequate level.

Management also monitors its liquidity by the net loans to deposits ratio. The
net loans (including loans held for sale) to deposits ratio was at 100.3% at
September 30, 2000 as compared to 92.0% at December 31, 1999 and 89.4% at
September 30, 1999. The Company's liquidity plan allows for the use of long-term
advances or short- term lines of credit with the Federal Home Loan Bank ("FHLB")
as a source of funds. Borrowing from the FHLB not only provides a source of
liquidity for the Company, but also serves as a tool to reduce interest rate
risk as well. The Company may structure borrowings from FHLB to match those of
customer credit requests, and therefore, lock in interest rate spreads over the
lives of the loans. At September 30, 2000, the Company continued to have one
such matched funding loan outstanding totaling $271,000.

The Company continues to also have short-term borrowing availability through
FHLB "RepoPlus" advances. "RepoPlus" advances are short-term borrowings maturing
within one year, bear a fixed rate of interest and are subject to prepayment
penalty. At September 30, 2000, the Company had $25.0 million in RepoPlus
advances outstanding used for general liquidity purposes.

In addition to borrowing from the FHLB as a source for liquidity, as mentioned
earlier, the Company also continued activity in the secondary mortgage market.
Specifically, the Company continues to sell fixed rate residential real estate
mortgages to Freddie Mac. The sales to Freddie Mac not only provide an
opportunity for the Company to remain competitive in the market place by
allowing it to offer a fixed rate mortgage product, but also provides an
additional source of liquidity. Loan sales on the secondary market also provides
management an additional tool to use in managing interest rate risk exposure
within the balance sheet. The Company continues to service all loans sold to
Freddie Mac.

The Statement of Cash Flows, for the nine-month period ended September 30, 2000,
indicates an increase in cash and cash equivalents of $2,150,000. Cash was
provided from a net increase in deposits of $23.1 million, an increase in
short-term borrowings of $16.0 million, and repayments of investment securities
available for sale of $2.1 million. Cash was used during the period for the
origination of loans held for sale of $6.3 million and for the origination of
loans of $39.8 million. Dividends paid during the nine-month period ended
September 30, 2000 totaled $830,000. Cash and cash equivalents totaled $13.5
million at September 30, 2000, an increase of $2,150,000 from $11.3 million at
December 31, 1999.

Management is not aware of any conditions, including any regulatory
recommendations or requirements, which would adversely affect its liquidity or
ability to meet its funding needs in the normal course of business.

The allowance for loan losses at September 30, 2000 totaled $1,923,000 or 0.86%
of total loans (including loans held for sale) as compared to $1,681,000 or
0.92% at December 31, 1999. Provisions for loan losses were $397,000 and
$315,000 for the nine-month periods ended September 30, 2000 and 1999.

Management performs a quarterly evaluation of the allowance for loan losses. The
evaluation incorporates internal loan review, actual historical losses, as well
as any negative economic trends in the local market. The evaluation is presented
to and approved by the Board of Directors of the Company. Management, through
the use of the quarterly evaluation, believes that the allowance is maintained
at an adequate level.

A loan is considered impaired when, based upon current information and events,
it is probable that the Company will be unable to collect all principal and
interest amounts due according to the contractual terms of the loan agreement.
At September 30, 2000, the Company had nonaccrual loans of $2,770,000, of which,
$2,007,000 were classified as impaired. The average balance in 2000 of impaired
loans was $1,990,000. Impaired loans had a related allowance allocation of
$304,000 and income recognized in 2000 for impaired loans totaled $6,000.

While impaired loans at September 30, 2000 were comprised of several loan
accounts, three borrowers accounted for $1.8 million of the total, of which one
borrower totaled $1.1 million. Two of the borrowers continued voluntary
liquidation of assets as part of work out arrangements with the Company. The
remaining borrower pertains to a participated loan for a dairy operation. The
Company was cross-collateralized on cattle, feed and real estate, including
facilities. Prior to year-end 1999, based on internal analysis, the Company
determined that a loss pertaining to the cattle portion of the credit was
eminent. Accordingly, management recorded a charge off in the amount of $300,000
during the fourth quarter of 1999, which represented the Company's portion of
the total loss. In addition, the remaining dairy herd has been sold with all
proceeds delivered to the Company. Management anticipated receiving deed in lieu
of foreclosure on the remaining real estate, until the borrower filed for
bankruptcy in the third quarter of 2000. Management is proceeding with
foreclosure procedures and has been granted permission from the bankruptcy court
to proceed with foreclosure action. Management continues negotiations with an
interested third party for a lease with an option to purchase and does not
consider any of the remaining non-performing loans to pose any significant risk
to the capital position or future earnings of the Company.

Management believes none of the non-performing assets, including other real
estate owned, at September 30, 2000, pose any significant risk to the
operations, liquidity or capital position of the Company.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Market risk for the Company is comprised primarily from interest rate risk
exposure and liquidity risk. Since virtually all of the interest-earning assets
and paying liabilities are at the Bank, virtually all of the interest rate risk
and liquidity risk lies at the Bank level. The Bank is not subject to currency
exchange risk or commodity price risk, and has no trading portfolio, and
therefore, is not subject to any trading risk. In addition, the Bank does not
participate in hedging transactions such as interest rate swaps and caps.
Changes in interest rates will impact both income and expense recorded and also
the market value of long-term interest-earning assets. Interest rate risk and
liquidity risk management is performed at the Bank level. Although the Bank has
a diversified loan portfolio, loans outstanding to individuals and businesses
are dependent upon the local economic conditions in the immediate trade area.

One of the principal functions of the Company's asset/liability management
program is to monitor the level to which the balance sheet is subject to
interest rate risk. The goal of the asset/liability program is to manage the
relationship between interest rate sensitive assets and liabilities, thereby
minimizing the fluctuations in the net interest margin, which achieves
consistent growth of net interest income during periods of changing interest
rates.

Interest rate sensitivity is the result of differences in the amounts and
repricing dates of a bank's rate sensitive assets and rate sensitive
liabilities. These differences, or interest rate repricing "gap", provide an
indication of the extent that the Company's net interest income is affected by
future changes in interest rates. During a period of rising interest rates, a
positive gap, a position of more rate sensitive assets than rate sensitive
liabilities, is desired. During a falling interest rate environment, a negative
gap is desired, that is, a position in which rate sensitive liabilities exceed
rate sensitive assets.

The Company's gap analysis indicates that if interest rates were to rise 100
basis points (1.00%), the Company's net interest income would decline at the one
year horizon because the Company's rate sensitive liabilities would reprice
faster than rate sensitive assets. Conversely, if rates were to fall 100 basis
points, the Company would earn more in net interest income.

Management also manages interest rate risk with the use of simulation modeling
which measures the sensitivity of future net interest income as a result of
changes in interest rates. The analysis is based on repricing opportunities for
variable rate assets and liabilities and upon contractual maturities of fixed
rate instruments.

The simulation also calculates net interest income based upon estimates of the
largest foreseeable rate increase or decrease, (+or - 200 basis points or
2.00%). The current analysis indicates that, given a 200 basis point overnight
movement in interest rates, the Bank would experience a potential $802,000 or 7%
change in net interest income. It is important to note, however, that this
exercise would be of a worst-case scenario. It would be more likely to have
incremental changes in interest rates, rather than a single significant increase
or decrease. When management believes interest rate movements will occur, it can
restructure the balance sheet and thereby the ratio of rate sensitive assets to
rate sensitive liabilities which in turn will effect the net interest income. It
is important to note; however, not all assets and liabilities with similar
maturities and repricing opportunities will reprice at the same time or to the
same degree and therefore, could effect forecasted results.

Much of the Bank's deposits have the ability to reprice immediately; however,
deposit rates are not tied to an external index. As a result, although changing
market interest rates impact repricing, the Bank retains much of the control
over repricing by determining itself the extent and timing of repricing of
deposit products. In addition, the Bank maintains a significant portion of its
investment portfolio as available for sale securities and also has a significant
variable rate loan portfolio, which is used to offset rate sensitive
liabilities.

Changes in market interest rates can also affect the Bank's liquidity position
through the impact rate changes may have on the market value of the available
for sale portion of the investment portfolio. Increases in market rates can
adversely impact the market values and therefore, make it more difficult for the
Bank to sell available for sale securities needed for general liquidity purposes
without incurring a loss on the sale. This issue is addressed by the Bank with
the use of borrowings from the Federal Home Loan Bank ("FHLB") and the selling
of fixed rate mortgages as a source of liquidity to the Bank.

The Company's liquidity plan allows for the use of long-term advances or
short-term lines of credit with the FHLB as a source of funds. Borrowing from
FHLB not only provides a source of liquidity for the Company, but also serves as
a tool to reduce interest risk as well. The Company may structure borrowings
from FHLB to match those of customer credit requests, and therefore, lock in
interest rate spreads over the lives of the loans.

In addition to borrowing from the FHLB as a source for liquidity, the Company
also participates in the secondary mortgage market. Specifically, the Company
sells fixed rate, residential real estate mortgages to the Federal Home Loan
Mortgage Corporation ("Freddie Mac"). The sales to Freddie Mac not only provide
an opportunity for the Bank to remain competitive in the market place, by
allowing it to offer a fixed rate mortgage product, but also provides an
additional source of liquidity and an additional tool for management to limit
interest rate risk exposure. The Bank continues to service all loans sold to
Freddie Mac.
