Item 2. Management's Discussion and Analysis of Financial
Condition and Results of Operations

Overview

	Net income of Firstar Corporation ("Firstar") for the
quarter ended March 31, 2000 was $307.8 million compared with
$287.6 million in the first quarter of 1999.  Diluted earnings per
common share was $.31 for the first quarter of 2000, compared
to $.29 for the same period of the prior year.

	Net income before merger-related charges was $342.4
million in the first quarter of 2000, a 15.2 % increase over the
$297.3 million in the same period of last year. Diluted earnings
per common share before merger-related charges was $.35 in the
first quarter of 2000, compared to $.29 in the first quarter of last
year, an increase of 20.7%.  Return on average assets before
merger-related charges was 1.90% in the first quarter of 2000
compared to 1.63% in the same period of last year.  Return on
average common equity before merger-related charges was
21.53% in the first quarter of 2000 compared to 17.83% in the
same period of last year.

	The improvement in net income before merger-related
charges for the quarter resulted from higher net interest revenue
and noninterest revenue together with significantly lower
operating costs.

	Total assets at March 31, 2000 were $73.1 billion
compared to $72.8 billion at December 31, 1999, while total
earning assets were $66.0 billion at March 31, 2000 compared to
$65.3 billion at last year-end.  Continued restructuring of the
balance sheet occurred during the quarter with the sale or transfer
of residential mortgage loans from the loan portfolio and changes
in the mix of investment securities. Loan growth was strong in
both the commercial and retail portfolios during the quarter. On
the liability side of the balance sheet, short-term borrowings
increased during the quarter to fund earning asset growth, to
offset the slight decrease in deposits from year-end and to fund
the stock buyback program.

	Total loans were $50.3 billion at March 31, 2000 compared
to $50.6 billion at year-end 1999.  Residential real estate loans
have declined reflecting management's decision to transfer $1.7
billion of the residential loan portfolio to loans held for sale.
Excluding residential real estate loans, total loans increased $1.8
billion, or 4.4%, since December 31, 1999.  Specifically, retail
loans, which include such areas as installment lending, auto
leasing and credit card services have increased $724 million, or
5.4%, led by a $496 million, or 24.7%, increase in retail leases.
Specialized lending and corporate loans increased $812 million
or 4.7% since December 31, 1999.  Commercial and
construction real estate loans increased $296 million or 2.7%
since December 31, 1999.  In the third quarter of 1998, Firstar
established a loan conduit, Stellar Funding Group, Inc.  At
March 31, 2000, $2.1 billion of short term, high quality, low
yielding commercial loans had been funded in the conduit
compared to $1.7 billion at December 31, 1999.

<PAGE>
	Total investment securities were $13.5 billion at March 31,
2000 compared to $13.1 billion at year-end 1999.  At March 31,
2000 the net unrealized loss on available for sale securities was
$231.4 million and the related after tax decrease to shareholders'
equity was $150.7 million.  Loans held for sale were $ 1.9
billion at March 31, 2000 compared to $625 million at December
31, 1999.  This increase resulted from the transfer of $1.7 billion
of loans from the residential mortgage portfolio.  As of March
31, 2000, $682 million of these transferred loans have been sold
in the secondary market.

	Total deposits were $51.4 billion at March 31, 2000, a
reduction of $462 million, or 0.9%, from year-end 1999.  Non-
interest bearing demand deposit balances declined by $348
million from year-end when deposit levels typically peak.
Interest-bearing deposits decreased by $114 million from
December 31, 1999. Merger-related branch divestitures reduced
deposits by $135 million during the first quarter of 2000.  The
shift in deposit preferences continues with reductions in savings
and NOW accounts, collectively down by $228 million.  Retail
deposit customers are seeking higher yields in deposit accounts
and alternative investment vehicles.  Short-term borrowed funds
of $9.4 billion at March 31, 2000 were up $1.1 billion since
year-end 1999 as additional funding was necessary to replace the
reduced levels of deposits and to fund earning asset growth.

Results of Operations

	Net interest income on a taxable equivalent basis, was
$681.9 million, an increase of $12.4 million, or 1.8%, as
compared to the first quarter of 1999. The increase in net interest
income was due to an improved mix of assets and liabilities, a
higher net interest margin and the impact of one additional day in
the first quarter of 2000.  This was partially offset by the lower
level of average earning assets.  Average earning assets for the
first quarter of 2000 were $65.6 billion, a reduction of $533
million from the same period of 1999.  This reduction was due to
the balance sheet restructuring as a result of the Mercantile
merger.

	Average retail loans increased by $2.4 billion or 21.1%,
which included a 48.5% increase in leases; a 19.8% increase in
home equity loans; a 16.7% increase in installment lending and a
10.1% increase in credit card loans. Average commercial loans
rose by $1.9 billion, or 11.8%.  Average total real estate loans
declined by $1.5 billion or 6.9%.  Commercial mortgage and
construction loans increased by $641 million or 6.1%.  This
growth was offset by a $2.1 billion decline in average residential
mortgage loans due to both maturities and repayments along with
the sale of new originated loans into the secondary market and
the transfer of loans to held for sale status.

	Average investment securities were reduced by $2.0
billion, or 13.1%, due to merger-related sales and restructuring
of the investment portfolio.  The change in mix of assets from
lower yielding investment securities and residential mortgages to
higher yielding loans have largely contributed to the increase in
net interest income.  This positive factor was partially offset by
the increased use of higher cost funding sources  and the overall
decrease in average earning assets.

Note:  Interest and average rate are presented on a fully-taxable equivalent basis.  Taxable equivalent amounts
       are calculated utilizing marginal federal income tax rate of 35 percent.  The yield on available for sale
       securities is based upon historical cost balances.  The total of nonaccruing loans is included in average
       amounts outstanding.

	The net interest margin increased by ten basis points to
4.17% in the first quarter of 2000 compared to the first quarter
of 1999.  The yield on total earning assets rose by 37 basis points
to 8.03%.  Likewise, the yield on total loans increased by 27
basis points reflecting generally market driven forces.  The
comparable rate paid on interest bearing liabilities increased by
23 basis points similarly reflecting higher market rates and more
reliance on higher cost purchased funds.  Interest spread, the
difference between the rate earned on total earning assets and the
rate paid on interest bearing liabilities increased by 14 basis
points.  The contribution of interest free funds to the net interest
margin declined by four basis points producing the net increase to
the margin of ten basis points.  The contribution of  interest free
funds was lessened by the higher proportion of earning assets
funded by interest bearing liabilities.  Tables 1 provides
detailed information on the average balances, interest
income/expense and rates earned or paid.

	Firstar's major market risk exposure is to changing interest
rates.  To minimize the volatility of net interest income to
adverse changes in interest rate, Firstar has established guidelines
for its asset and liability activities through its Asset/Liability
Policy Committee.  This committee has the responsibility for
approving and ensuring compliance with policies including
interest rate risk exposure, off-balance-sheet activity and the
investment portfolio position.

	One of the primary tools to measure interest rate risk and
the effect of interest rate changes on net interest income is
simulation analysis.  This earnings simulation model estimates
net interest income under a variety of scenarios that incorporate
changes in the shape of the yield curve, changes in interest rate
relationships, changes in the direction of rates, and changes in
the mix and levels of balance sheet accounts.  The most recent
simulation projected the impact of a 100 basis point upward or
downward gradual change of market interest rates over a one
year time period.  The results of this simulation indicate that a
declining interest rate scenario would increase net interest
revenue by $12 million from a base case, while an increasing rate
scenario would decrease net interest revenue by $8 million.

	The loan loss provision charged to earnings in the first
quarter of 2000 was $45.7 million, compared to $43.4 million
during the same period of last year.  Net loan charge-offs were
$45.6 million in the first quarter of 2000 compared to $37.2
million a year earlier.  First quarter 2000 net charge-offs were
 .36% of average loans compared with .31% in the same quarter
of last year.  Management has continued to focus on growing
consumer loans as a higher percentage of total loans and, as a
result of this, would expect charge-offs to be somewhat greater
during the remainder of 2000.

	Noninterest income is a significant source of revenue for
Firstar, representing 34.6% of tax equivalent net revenue in the
first quarter of 2000 compared to 32.8% in the same quarter of
1999, excluding securities gains.  Noninterest income, excluding
securities gains, increased by $34.7 million, or 10.6%, to a level
of $361.2 million in the first quarter of 2000 when compared to
the same quarter of last year.

	Trust income is the largest source of noninterest income for
Firstar and in the first quarter of 2000 increased $12.3 million,
or 12.2% due to new business in all product lines and higher
stock market values.  Additionally, this year's trust income
benefited from one-time changes to accrual procedures, which
increased revenues by $3.7 million.  Retail deposit income
increased $2.4 million or 5.4%. Credit card income increased
$5.4 million or 22.3% due to an expanded customer base and
increased card usage. Electronic banking income increased $3.6
million or 42.9% and included $2.9 million of one-time income
from resolution of reconciling issues. Cash management income
increased by $3.1 million or 9.5% and included one-time changes
in accrual procedures, which increased revenues by $3.0 million.
Mortgage banking revenue declined by $3.2 million or 8.0%
with reduced loan gains of $13.0 million partially offset by
increased gains on the sale of servicing rights of $6.6 million.
Securitization revenue increased  by $11.7 million or 170.6% due
to the establishment and continued placement of loans and
investments in conduits which provide management and referral
fees to Firstar.  Brokerage revenue declined as a result of the
outsourcing of that product to a third party broker.  Table 2
shows the components of noninterest income.

	Noninterest expense, excluding merger-related expenses,
totaled $453.9 million, a decrease of $51.9 million, or 10.3%,
from the first quarter of 1999.

	Staff expense for the first quarter of 2000 decreased $37.6
million, or 14.5%.  This decrease resulted from staff reductions
in support and back room operations as a result of mergers and
lower accruals for incentive programs.  Employee benefits
expense also declined during the quarter due to lower headcount
and salary levels, the merger of employee benefit plans and
reduced pension costs resulting from increased cash contributions
to the pension plan.  Partially offsetting these decreases were
increases in staff as a result of opening new branches and in-store
locations.

	Occupancy expenses declined $3.3 million, or 7.5%, due to
the consolidation of facilities related to recent mergers.
Marketing costs declined $4.5 million, or 36.3%, from the first
quarter of last year.  Marketing costs will increase in future
periods with the introduction of new products and additional
marketing emphasis in the Mercantile banks' markets. All other
operating expenses declined an aggregate $6.6 million, or 3.5%,
reflecting an $8.5 million reversal of excess expense accruals
from prior periods.  Table 3 shows the components of noninterest
expenses.

	Before merger-related costs, Firstar's efficiency ratio was
43.52% in the first quarter of 2000, a significant improvement
over the 50.13% of the same quarter of last year.

	Merger-related charges totaled $51.9 million in the first
quarter of 2000 compared to $15.0 million in the same period of
last year.  Note 7 to the financial statements provides a summary
of merger-related costs and activity in the accrual accounts.

	The effective income tax rate was 35.8% in the first quarter
of 2000 compared to 33.2% in the same period of last year.  The
increase in the effective tax rate was due to a tax refund
recognized in 1999 along with lower tax exempt revenues relative
to taxable income.

Asset Quality

	As of March 31,2000, the allowance for loan losses was
$715.0 million, or 1.42% of loans outstanding compared to
1.41% at December 31, 1999 and 1.46% a year earlier.  The
decrease from the prior year resulted from a change in the
management of problem loans as a result of the Firstar merger
when a more aggressive charge-off policy had been adopted.  The
allowance as a percentage of nonperforming loans was 322% at
March 31, 2000 compared to 341% at December 31, 1999 and
309% a year earlier.  Table 4 provides a summary of activity in
the allowance for loan losses by type of loan.  Net charge-offs
totaled $45.6 million in the first quarter of 2000 compared with
$37.2 million in the same period of last year.  Annualized net
charge-offs as a percent of average loans increased from .31% in
the first  quarter of 1999 to .36% in the first quarter of this year.
Credit card net charge-offs decreased from 4.67% of average
outstandings in 1999 to 4.45% in the first quarter of 2000.
Commercial loan net charge-offs increased from a level of .25%
of loans in 1999 to.30% in the same period of 2000.  Other retail
lending net charge-offs increased  from .37% of average
outstandings in 1999 to .46% in the current period.
Management anticipates the level of net charge-offs to trend
higher over the remainder of 2000 with the continued emphasis
on expanding retail lending.

	Nonperforming assets, as shown in Tables 5 and 6, were
$241.8 million at March 31, 2000.  This is an increase of $12.9
million from December 31, 1999 and a $15.5 million reduction
from a year earlier.  Measured as a percent of loans and other
real estate, nonperforming assets have decreased from .53% at
March 31, 1999 to .48% at March 31, 2000.  Lower levels of
retail nonaccrual loans and other real estate owned was partially
offset by higher levels of commercial nonaccrual loans.

Capital Resources

	Total shareholders' equity was $6.27 billion at March 31,
2000, a decrease of $39.9 million from December 31, 1999 and
$511.0 million from a year earlier.  These declines are the result
of strong core earnings offset by dividend payments, the merger-
related charges, the stock repurchase program and unrealized
losses on investment securities reflected in other comprehensive
income.  The tangible common ratio was 6.85% at March 31,
2000, compared to 6.83% at December 31, 1999 and 7.10% a
year earlier.  The ratio of total shareholders' equity to total assets
was 8.58% at March 31, 2000 compared to 8.67% at December
31, 1999 and 9.21% at March 31, 1999.

	Banking industry regulators define minimum capital
requirements for bank holding companies.  At March 31, 2000,
Firstar's Tier I and Total Risk-Based Capital ratios amounted to
8.04% and 10.67%, respectively well above the minimum
requirements of 4.00% for Tier I and 8.00% for Total Risk-
Based Capital.  This compares to Tier I and Total Risk-Based
Capital ratios of 9.51% and 11.75% at March 31, 1999.
Regulatory authorities have also established a minimum leverage
ratio of 4.00%, which is defined as Tier I equity to average
quarterly assets.  For the first quarter of 2000, the Firstar's
average leverage ratio was 7.56% compared to 7.70% in the
same quarter of 1999.  These declines since 1999 were due to the
stock repurchase program and changes in balance sheet mix of
earning assets.  These regulatory ratios continue to be in excess
of stated "well capitalized" requirements.
