     as a percent of total assets                  0.26%               0.15%
</TABLE>

Loans are placed on nonaccrual status when in the judgement of management, the
probability of collection of interest is deemed to be insufficient to warrant
further accrual. All loans which are 90 or more days delinquent are treated as
nonaccrual loans. The amount of interest income of nonaccrual loans that had not
been recognized in interest income was $119 at December 31, 1999 and $102 at
June 30, 1999.

Nonaccrual, substandard and doubtful commercial and other real estate loans are
assessed for impairment, however, the Bank had no loans classified as impaired
at December 31, 1999. Impaired assets include $1,168 of foreclosed real estate
as of December 31, 1999, which is recorded at the lower of acquisition costs or
fair value.

4.  Comprehensive Income
Sources of comprehensive income not included in net income are limited to
unrealized gains and losses on certain investments in equity securities. For the
six months ended December 31, 1999 and 1998, total comprehensive income amounted
to $5,432 and $6,792, respectively.

RESULTS OF OPERATIONS - COMPARISON OF THREE MONTHS ENDED DECEMBER 31, 1999 AND
1998

For the three months ended December 31, 1999, Parkvale reported net income of
$3.2 million or $0.54 per diluted share up 8.9%, or 17.4% on a per share basis,
from net income of $3.0 million or $0.46 per diluted share for the quarter ended
December 31, 1998. The $265,000 increase in net income for the December 1999
quarter reflects increased net interest income of $998,000 and increased fee
income of $134,000, which are partially offset by an increase in other expense
of $428,000. Net interest income increased to $8.6 million from $7.6 million for
the quarter ended December 31, 1998. The higher percentage increase in earnings
per share was the result of fewer outstanding shares in the current quarter due
to ongoing stock repurchase programs. Return on average equity increased to
16.5% for the December 1999 quarter compared to 14.79% for the December 1998
quarter.

INTEREST INCOME:
Parkvale had interest income of $20.9 million for the three months ended
December 31, 1999 versus $19.8 million during the comparable period in 1998.
This increase of $1.1 million or 5.4% is the result of a $53 million or 4.7%
increase in the average balance of interest-earning assets and a 4 basis point
increase in the average yield from 7.06% in 1998 to 7.10% in 1999. Interest
income from loans increased $1.6 million or 9.3% resulting from an increase in
the average outstanding loan balances of $103.9 million or 11.5%, offset
slightly by a 15 basis point decrease in the average yield from 7.45% in 1998 to
7.30% in 1999. Interest income on mortgage-backed securities decreased $254,000
or 39.6% from the 1998 quarter due to a decrease of $14.7 million or 39.8% in
the average balance. Investment interest income increased by $523,000 or 52.7%
from the 1998 quarter due to a 72 basis point increase in the average yield from
5.20% in 1998 to 5.92% in 1999 and an increase of $26.1 million or 34.2% in the
average balance. The investment portfolio includes $58.8 million invested in
various corporate bonds and trust preferred securities throughout calendar year
1999 yielding 6.82%. Interest income earned on federal funds sold decreased
$753,000 or 55.0% from the 1998 quarter due to a decrease in the average balance
of $62.3 million or 58.0% offset somewhat by a 35 basis point increase in the
average yield from 5.09% in 1998 to 5.44% in 1999. At December 31, 1999, the
weighted average yield on all interest-earning assets was 7.31% compared to
7.20% at December 31, 1998.

INTEREST EXPENSE:
Interest expense increased by $79,000 or 0.7% from the 1998 quarter to the 1999
quarter. This minimal increase was due to an increase in the average deposits
and borrowings of $66.4 million or 6.35%, offset by a 25 basis point decrease in
the average rate paid on deposits and borrowings from 4.66% in 1998 to 4.41% in
1999. At December 31, 1999, the average rate payable on liabilities was 4.45%
for deposits, 5.48% for borrowings and 4.50% for combined deposits and
borrowings.

PROVISION FOR LOAN LOSSES:
Parkvale's provision for loan losses increased by $3,000 or 5.8% from the 1998
quarter to the 1999 quarter. Aggregate valuation allowances were 1.31% of gross
loans at December 31, 1999, 1.30% of gross loans at June 30, 1999 and 1.35% of
gross loans at December 31, 1998. Total loan loss reserves at December 31, 1999
were $13.4 million.

Nonperforming loans and real estate owned were $4.3 million, $3.3 million and
$3.9 million at December 31, 1999, June 30, 1999 and December 31, 1998,
representing 0.35%, 0.27% and 0.34% of total assets at the respective balance
sheet dates. The increase in fiscal 2000 relates primarily to delinquent
mortgage loans in single family owner occupied homes.

<PAGE>   11


OTHER INCOME:
Total other income decreased by $166,000 or 16.0% for the December 1999 quarter
as a result of the $300,000 gain from the sale of equity securities,
specifically Freddie Mac stock, realized during the 1998 quarter. Absent this
gain, other income increased $134,000 or 18.2%, primarily due to increased
service charges on all types of deposit and loan products.

OTHER EXPENSE:
Total other expenses increased by $428,000 or 11.1% from quarter ended December
1998 to the quarter ended December 1999. This increase is due principally to
increases in compensation and office occupancy of $326,000 and $63,000, or 16.0%
and 10.2%, respectively. Parkvale opened a new branch office and utilized
additional headquarters office space since December 1998. Compensation has risen
due to additional personnel to support a new in-house data processing system
installed in September 1999. Annualized noninterest expenses as a percentage of
average assets were 1.42% for the quarter ended December 31, 1999 as compared to
1.34% for the quarter ended December 31, 1998.


RESULTS OF OPERATIONS - COMPARISON OF SIX MONTHS ENDED DECEMBER 31, 1998 AND
1997

For the six months ended December 31, 1999, Parkvale had net income of $6.4
million or $1.06 per diluted share versus $6.0 million or $0.91 per diluted
share for the comparable period in 1998. The $461,000 or 7.7% increase in net
income for the six months ended December 31, 1999 reflects increased net
interest income of $1.8 million and increased fee income of $325,000, these
items were partially offset by increased operating expenses of $808,000. Net
interest income for the six months ended December 31, 1999 increased to $17.0
million from $15.2 million for the six months ended December 31, 1998.

INTEREST INCOME:
Parkvale had interest income of $41.4 million during the six months ended
December 31, 1999 versus $39.2 million during the comparable period in 1998. The
increase of $2.1 million is attributable to an increase in the average
interest-earning asset portfolio of $76.1 million or 6.9%, offset by an 11 basis
point decrease in the average yield from 7.16% in 1998 to 7.05% in 1999.
Interest income from loans increased $3.6 million or 11.06% due to an increase
in the average loan balance of $135.0 million or 15.5%, offset by a 29 basis
point decrease in the average yield from 7.54% in 1998 to 7.25% in 1999.
Interest income on mortgage-backed securities declined by $531,000 or 39.3% from
the first six months of the previous fiscal year. This was due to a decrease in
the average portfolio of $15.1 million or 39.1%, compounded by a 3 basis point
decrease in the average yield from 7.00% to 6.97%. Income from investments
increased by $1.1 million or 60.2% from 1998 due to an increase in the average
investment balance of $32.8 million or 49.3% and a 40 basis point increase in
the average yield from 5.45% in 1998 to 5.85% in 1999. Interest income earned on
federal funds sold decreased $2.1 million or 64.7% from the prior six months
ended December 1998. This was due to a decrease of the average federal fund
balance of $76.6 million or 64.3%, coupled with a 6 basis point decrease in the
average yield from 5.40% in 1998 to 5.34% in 1999.

INTEREST EXPENSE:
Interest expense increased by $327,000 or 1.4% from the 1998 six month period to
the 1999 six month period. The small increase was due to a rise in average
deposits and borrowings of $82.3 million offset by a 29 basis point decrease in
the average rate paid from 4.69% in 1998 to 4.40% in 1999.

PROVISION FOR LOAN LOSSES:
Parkvale's provision for loan losses decreased by $27,000 or 23.5% from the 1998
to the 1999 six month period. Aggregate valuation allowances were 1.31% of gross
loans at December 31, 1999, 1.30% of gross loans at June 30, 1999 and 1.35% of
gross loans at December 31, 1998. Total loan loss reserves at December 31, 1999
were $13.4 million.

Nonperforming loans and real estate owned were $4.3 million, $3.3 million and
$3.9 million at December 31, 1999, June 30, 1999 and December 31, 1998,
representing 0.35%, 0.27% and 0.34% of total assets at the respective balance
sheet dates.

OTHER INCOME:
Other income decreased by $285,000 or 13.8% for the six months ended December
31, 1999 from the six months ended December 31, 1998 as a result of the $610,000
gain from the sale of equity securities, specifically Freddie Mac stock,
realized during the first six months of 1998. Excluding this gain, other income
increased $325,000 or 22.4%, primarily due to increased service charges on all
types of deposit and loan products.

OTHER EXPENSE:
Other expenses increased by $808,000 for the six month period ended December 31,
1999 from same period in 1998. This increase is due principally to increases in
compensation and office occupancy of $451,000 and $165,000, or 10.8% and 14.4%,
respectively. Parkvale opened a new branch office and taken over additional
office space in the headquarters building since December 1998. Compensation has
risen mainly due to additional personnel and overall training costs to support
the conversion to a new in- house data processing system completed during
September 1999. Annualized noninterest expenses as a percentage of average
assets were 1.41% for the six months ended December 31, 1999 as compared to
1.35% for the six months ended December 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES:
Federal funds sold decreased $22.6 million or 35.2% from June 30, 1999 to
December 31, 1999 as a result of increased loan balances of $14.6 million,
increased investment balances of $12.5 million and increased cash balances of
$5.2 million, mitigated somewhat by increased deposit balances of $18.6 million.
Escrow for taxes and insurance decreased by $1.9 million or 21.0% as a result of
the remittance of property taxes to the various taxing districts during the
first quarter.

Shareholders' equity was $81.7 million or 6.75% of total assets at December 31,
1999. The Bank is required to maintain Tier I (Core) capital equal to at least
4% of the institution's adjusted total assets, and Tier II (Supplementary)
risk-based capital equal to at least 8% of the risk-weighted assets. At December
31, 1999, Parkvale was in compliance with all applicable regulatory
requirements, with Tier I and Tier II ratios of 6.40% and 11.77%, respectively.

Management is not aware of any trends, events, uncertainties or current
recommendations by any regulatory authority that will have (if implemented), or
that are reasonably likely to have, material adverse effects on Parkvale's
liquidity, capital resources or operations.

IMPACT OF YEAR 2000:
Parkvale's year 2000 ("Y2K") plan was discussed on Page 12 of the 1999 Annual
Report included in the 1999 Form 10-K filed in September 1999. The system
conversion was successfully completed as scheduled on September 6, 1999. The
Bank conducted business as usual on Saturday, January 1, 2000, without incident,
and continues to operate without interruption. Management remains focused on
monitoring and validating daily activity to ensure uninterrupted customer
service throughout the year 2000.

IMPACT OF INFLATION AND CHANGING PRICES:
The financial statements and related data presented herein have been prepared in
accordance with generally accepted accounting principles, which require the
measurement of financial position and operating results in terms of historical
dollars without considering changes in the relative purchasing power of money
over time due to inflation. Unlike most industrial companies, substantially all
of the assets and liabilities of a financial institution are monetary in nature.
As a result, interest rates have a more significant impact on a financial
institution's performance than the effects of general levels of inflation.
Interest rates do not necessarily move in the same direction or in the same
magnitude as the prices of goods and services as measured by the consumer price
index.
