                            AMERICORP AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - BASIS OF PRESENTATION

The accompanying financial information has been prepared in accordance with the
Securities and Exchange Commission rules and regulations for quarterly reporting
and therefore does not necessarily include all information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles. This information should be read
in conjunction with Americorp's Form 10K filed on March 28, 2000.

The consolidated financial statements include Americorp and its wholly owned
subsidiary, American Commercial Bank (the "Bank").

Operating results for interim periods are not necessarily indicative of
operating results for an entire fiscal year. In the opinion of management, the
unaudited financial information for the three month and nine month periods ended
September 30, 2000 and 1999, reflect all adjustments, consisting only of normal
recurring accruals and provisions, necessary for a fair presentation thereof.

Some matters discussed in this Form 10-Q may be "forward-looking statements"
within the meaning of the Private Litigation Reform Act of 1995 and therefore
may involve risks, uncertainties and other factors which may cause our actual
results to be materially different from the results expressed or implied by our
forward-looking statements. These statements generally appear with words such as
"anticipate," "believe," "estimate," "may," "intend," and "expect."


NOTE 2 - EARNINGS PER SHARE

Effective December 31, 1997, the Company adopted Statement of Financial
Accounting Standards No. 128, "EARNINGS PER SHARE". Accordingly, basic earnings
per share are computed by dividing income available to common shareholders by
the weighted average number of common shares outstanding during each period. The
computation of diluted earnings per share also considers the number of shares
issuable upon the assumed exercise of outstanding common stock options.


NOTE 3 - STOCK SPLIT

On March 18, 1999, the Board of Directors of the Company declared a two-for-one
stock split of its outstanding shares of common stock. The effective date for
the split was April 15, 1999 and the additional shares issued pursuant to the
stock split were distributed on May 8, 1999.

All per share data has been retroactively adjusted to reflect this split.

ITEM 2.         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                RESULTS OF OPERATIONS


INCOME SUMMARY

Americorp reported net earnings of $2,649,000 or $1.26 basic income per share
for the first nine months of 2000. This represents a 34.3% increase over the
same period during 1999 when net earnings were $1,973,000 or $0.95 basic income
per share. This increase principally resulted from a $1,228,000 increase in net
interest income. For the quarter ended September 30, 2000, net earnings were
$964,000, up from the $896,000 reported for the same quarter in 1999.

Annualized return on average assets for the three months and nine months ended
September 30, 2000 was 1.49% and 1.41%, respectively, compared with 1.47% and
1.08% for the same periods in 1999. Return on average assets for the year ended
December 31, 1999 was 1.36%.

Annualized return on average equity for the three months and nine months ended
September 30, 2000 was 15.93% and 14.88%, respectively, compared with 16.58% and
12.39% for the same periods in 1999. Return on average equity for the year ended
December 31, 1999 was 15.32%.

Quarterly cash dividends of $0.13 per share were declared in the third quarter
of 2000, compared to $0.11 per share declared in the third quarter of 1999.

NET INTEREST INCOME

Net interest income is the amount by which the interest and amortization of fees
generated from loans and other earning asset exceeds the cost of funding those
assets, usually deposit account interest expense. Net interest income depends on
the difference (the "interest rate spread") between gross interest and fees
earned on the loans and investment portfolios and the interest rates paid on
deposits and borrowings.

The following table sets forth the components of net interest income, average
earning assets and net interest margin:

NET INTEREST INCOME - CONTINUED

Net interest income was $4.0 million for the quarter ended September 30, 2000,
compared to $3.8 million for both the first and second quarters of 2000. Net
interest margin was 6.98% for the third quarter of 2000 compared to a
year-to-date 2000 net interest margin of 6.95%.

Net interest income was $11.7 million for the nine months ended September 30,
2000, compared to the $10.4 million for the nine months ended September 30,
1999. The $1,228,000 increase in net interest income was the result of the
combination of increases in total earning assets, a significant change in the
mix of earning assets and multiple increases in the prime rate in late 1999 and
early 2000. Americorp experienced significant growth in loans from $172.0
million at September 30, 1999 to $199.0 million at September 30, 2000. Since
loans are the Company's highest interest earning assets, this loan growth has
increased the amount of net interest income and the net interest margin.

The net interest margin in the first nine months of 2000 was 6.95% compared to
6.47% for the same period in 1999. The first nine months of 2000 and 1999 were
impacted by the prime rate changes. The prime rate for the first nine months in
2000 increased 100 basis points to end the period at 9.5% whereas the prime rate
in the first nine months of 1999 increased 50 basis points to end the period at
8.25%. The majority of the Bank's loans and its investments in federal funds
sold reprice daily with changes in the prime rate. Deposits generally reprice at
a slower pace, therefore increasing the net interest margin in the short run.
Management increases the rates on deposits based on market conditions and is
therefore unable to predict the timing of these increases or the ultimate impact
on the Company's future net interest margin.

The prime rate was 8.25% for the first nine months of 1999, and then experienced
a 25 basis points increase in November to end the year at 8.50%. Prime continued
to rise in 2000 with 25 basis points increases in February and March and a 50
basis points increase in May to end the first nine months of 2000 at 9.50%

PROVISION FOR LOAN LOSSES

Americorp made a $414,000 contribution to the allowance for loan losses in the
first quarter of 2000 and a $250,000 contribution for the second and third
quarters of 2000. Management believes that the allowance, which equals 1.43% of
total loans at September 30, 2000, is adequate to cover future losses. The
allowance for loans losses at September 30, 1999 was 1.17% of total loans.

Changes in the  allowance  for loan losses for the quarter and nine months ended
September 30, 2000 and 1999 are as follows (dollar amounts in thousands):

Noninterest Income

Noninterest income represents deposit account services charges and other types
of non-loan related fee income. Noninterest income for the quarter ended
September 30, 2000 totaled $650,000, down $170,000 from the $820,000 reported
for the same period in 1999. Noninterest income for the nine months ended
September 30, 2000 totaled $1,997,000, compared to the $2,111,000 reported for
the same period in 1999. The third quarter and year to date declines were the
result of a 1999 gain on sale of other real estate owned and a 2000 decrease in
other fee income.

NONINTEREST EXPENSE

Noninterest expense represents salaries, occupancy expenses, professional
expenses, outside services and other miscellaneous expenses necessary to conduct
business. Noninterest expense for the quarter ended September 30, 2000 totaled
$3,065,000 compared to $2,808,000 for the same period of 1999. The third quarter
increase is due to an increase in other real estate owned expenses resulting
from a bank loan foreclosure during the third quarter, as well as increased
costs for insurance and professional fees.

Noninterest expense for the nine months ended September 30, 2000 totaled
$9,080,000 up slightly from the $8,821,000 for the same period in 1999. As an
annualized percent of average assets, noninterest expense was 4.82% and 4.80%
for the first nine months of 2000 and 1999, respectively.

INCOME TAXES

The Company's income tax provision for the first nine months of 2000 was
$1,030,000, resulting in an effective rate of 28.0% on income before taxes. This
rate compares to the 25.6% reported for the year ending December 31, 1999. The
Company's effective tax has increased due to the remaining tax credits being
utilized in 2000.

BALANCE SHEET ANALYSIS

Total assets at September 30, 2000 totaled $262.2 million, an increase of $16.2
million or 6.6% from December 31, 1999. The majority of this growth was centered
in loans, which increased $18.2 million or 10.0%. Deposits have increased by
$24.9 million or 11.9% during the first nine months of 2000. This increase was
used to fund the assets growth described above as well as retire $10 million in
short-term borrowing present at December 31, 1999.

The primary ratios of loan quality have improved in the first nine months of
2000. Nonperforming loans as a percent of total loans decreased to 0.69% at
September 30, 2000, compared to 0.99% at December 31, 1999. Likewise, the
allowance for loan losses as a percent of nonperforming loans increased to
208.76% at September 30, 2000, from 109.65% at December 31, 1999. The ratio of
the allowance for loan losses to total loans has increased from 1.09% at
December 31, 1999 to 1.43% at September 30, 2000. The decrease in nonperforming
assets was the result of a sale of other real estate owned and the pay off of a
nonaccrual loan.

The OREO property held by the bank at December 31, 1999 was sold during the
third quarter of 2000, a minor gain on sale was recorded. At September 30, 2000,
Americorp had one property in OREO with a total book value of $380,000. This
property was converted to OREO during the third quarter of 2000.

CAPITAL

Total  shareholders  equity at September 30, 2000 totaled $24.6  million,  which
represents a 12.0% increase from $21.9 million at September 30, 1999.

On February 26, 2000, the Company established a stock repurchase program for up
to 200,000 shares of Americorp's outstanding common stock. As of September 30,
2000, 37,181 shares had been repurchased under this program.

LIQUIDITY

Management is not aware of any future capital expenditures or other significant
demands on commitments which would severely impair liquidity.

ITEM 3.         QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK

In Management's opinion there has not been a material change in Americorp's
market risk profile during the nine months ended September 30, 2000. Market risk
is the risk of loss in a financial instrument arising from adverse changes in
market prices and rates, foreign currency exchange rates, commodity prices and
equity prices. Americorp's market risk arises primarily from interest rate risk
inherent in its lending and deposit taking activities. To that end, management
actively monitors and manages its inherent rate risk exposure. Americorp does
not have any market risk sensitive instruments acquired for trading purposes.
Americorp manages its interest rate sensitivity by matching the repricing
opportunities on its earning assets to those on its funding liabilities.
Management uses various asset/liability strategies to manage the repricing
characteristics of its assets and liabilities to ensure that exposure to
interest rate fluctuations is limited within Americorp's guidelines of
acceptable levels of risk-taking.

At September 30, 2000, Americorp had $144.7 million of assets and $154.5 million
of liabilities repricing within one year. Therefore, $9.8 million more in
interest rate sensitive liabilities than interest rate sensitive assets will
change to the then current rate (changes occur due to the instruments being at a
variable rate or because the maturity of the instrument requires its replacement
at the then current rate). Generally, if rates were to fall during this period,
interest expense would decline by a greater amount than interest income and net
income would increase. Conversely, if rates were to rise, the reverse would
apply, and Americorp's net income would decrease. However, the recent increase
in the prime rate has increased Americorp's net interest income in the short run
as asset rates generally reprice faster than liability rates.

See also the previous discussion on net interest income in ITEM 2 - MANAGEMENT'S
DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - NET
INTEREST INCOME.

YEAR 2000 RISK

During the periods leading up to January 1, 2000, Americorp addressed the
potential problems associated with the possibility that the computers that
control or operate Americorp's information technology system and infrastructure
may not have been programmed to read four-digit date codes and, upon arrival of
the year 2000, may have recognized the two-digit code "00" as the year 1900,
causing systems to function or generate erroneous data.

Americorp expended approximately $243,000 through the periods ended December 31,
1999 in connection with its Year 2000 compliance program. Americorp experienced
no significant problems related to its information technology systems upon
arrival of the Year 2000, nor was there any interruption in service to its
customers of any kind.

The Company does not expect, and to date has not realized, any significant
impact to net earnings or cash flow from Year 2000 risks.
