Note 1.  Basis of Presentation

  These condensed consolidated financial statements have been

It is suggested that these financial statements be read in

  These condensed consolidated financial statements include the

Note 8. Merger and Related Charges
- ----------------------------------
  Firstar recorded merger and integration charges of $243.0 
million in 1998 and $15.0 million in the first quarter 
of 1999.  Merger and integration charges were associated 
with the mergers of Firstar Corporation and Star Banc 
Corporation in the fourth quarter of 1998 and the 
acquisition of Trans Financial Inc. in the third
quarter of 1998.  The components of the charges are 
shown below.  (dollars in thousands)

of operations of Firstar Corporation and Star Banc 
Corporation.


Note 9. Mortgage Servicing Assets
- ---------------------------------
  Mortgage servicing rights are capitalized based upon
their fair value at the time a loan is sold.  Impairment 
testing is performed on a quarterly basis in accordance 
with SFAS No. 125 which was adopted by Firstar in 1997.   

  The fair value of capitalized mortgage servicing rights 
was $202.3 million on March 31, 1999 and $199.8 million 
on December 31, 1998.  Firstar serviced $14.9 billion of 
mortgage loans for other investors as of March 31, 1999 
and  $14.7 billion of mortgage loans for other
investors as of December 31, 1998.  

  Changes in capitalized mortgage servicing rights at 
March 31, 1999 and  December 31, 1998 are summarized 
in the following table.  (dollars in thousands)

Note 11.  Pending Acquisitions
- ------------------------------
  On April 30, 1999, Firstar Corporation and Mercantile 
Bancorporation Inc. signed a definitive agreement to 
merge through an exchange of shares.  Under the terms 
of the agreement, Mercantile shareholders will receive 
2.091 shares of Firstar common stock for each share of 
Mercantile common stock.  The combined company will have 
assets of approximately $75 billion.  The merger is 
expected to be completed in the fourth quarter of 
1999 and, subsequent to regulatory and shareholder
approvals, will be accounted for as a pooling of
interests.

  A summary of unaudited pro forma financial information
giving effect to the merger is shown below.  The 
unaudited financial information is not indicative of the 
results that would have been realized had the entities 
been a single company during these periods, nor is it 
indicative of the actual results the combined company 
will report in the future.

Note 12.  Business Segments
- ---------------------------
  Firstar's operations include three primary business segments:
Consumer Banking, Wholesale Banking, and Trust and Private Banking.
Selected financial information by business segment is summarized below.
This information is derived from the internal reporting systems used by
management to assess segment performance.

  Consumer banking provides deposit, installment and credit card
lending, mortgage banking, leasing, investment, payment systems and
other financial services to individuals and small businesses.  These
services are provided through retail branch offices, ATMs, voice
banking, PC and video banking options.
 
  Wholesale banking provides traditional business lending, asset-
based lending, commercial real estate loans, equipment financing,
cash management services and international trade services to businesses
and governmental entities.
 
  Trust and private banking provides personal financial and asset
management services, comprehensive employee benefit plan services,
mutual fund custody and corporate bond and stock transfer services.
 
  Treasury includes the net effect of transfer pricing of interest
income and expense along with the operating results of the investment
securities and residential loan portfolios.  All revenue and expenses
of administrative and support functions has been allocated to the
primary business segments.
 
  Certain asset balances have been reclassified between business
segments during the first quarter of 1999.  Prior year segment data has
been restated to be comparable to the current period's presentation.

  Additionally, transfer pricing methodology used for allocating net
interest income for certain asset and liability categories is different
from that used in the prior year's reporting.  The transfer pricing
methodology used in the first quarter of 1999 was based upon the 
anticipated cash flows ("cash flow method") of underlying assets and 
liabilities.  During 1998, net interest revenue was allocated to segments 
based upon average maturities ("average maturity method") of the 
underlying assets and liabilities.  Accurate data related to the 
anticipated cash flows of the underlying assets and liabilities for
periods during 1998 or data related to average maturities of assets and
liabilities during 1999 is impracticable to cost effectively obtain.
Therefore, segment information for 1998 has not been restated using the
cash flow method.  Additionally, restatement of segment information for
1999 determined under the average maturity method is also impracticable.

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, 1999 was $169.6 million, a 22.2% 
increase over the first quarter of 1998.  Diluted earnings 
per common share was $.25 for the first quarter of 1999, 
compared to $.21 for the same period of the prior year, an 
increase of 17.9%.  All per share amounts have been 
restated for the three for one stock split completed as of 
March 31, 1999.  Return on average assets was 1.80% for the 
first quarter of 1999, compared to 1.64% for the same 
period in 1998.  Return on average common equity was 
18.81% compared to 18.30% in the first quarter of last 
year.

  Included in the first quarter of 1999 expenses were 
$15.0 million of merger related charges relating to the 
November 1998 merger of Star Banc Corporation and Firstar.  
Firstar anticipates a total of $325.0 million of 
restructuring and merger related charges of which $232.0
million have been recognized through the end of the first 
quarter of this year.  

  Excluding the merger related charges, net income for 
the first quarter would have been $179.3 million, an 
increase of 29.1% over the first quarter of 1998.  First 
quarter 1999 diluted earnings per common share, before 
merger-related charges, was $.27, or a 28.6% increase 
over the same quarter of last year.  Return on average 
assets was 1.90% and return on average common equity 
was 19.88% in the first quarter of 1999, excluding 
merger-related charges.

  The improvement in net income before merger-related 
charges resulted from higher net interest revenue and 
noninterest revenue partially offset by somewhat higher 
operating costs and an increased loan loss provision.

Financial Condition 

  Total assets at March 31, 1999 were $37.95 billion,
up $524 million from the $38.48 billion level at 
December 31, 1998.  Total loans increased $459 million, 
or 1.8% from last year end to $26.33 billion at 
March 31, 1999.  Retail loans increased by $280.2 million,
or 3.7%, to $7.77 billion at March 31, 1999.  Strong growth
in retail installment loans and leases of 4.0% and 8.6%, 
respectively, were achieved in the first quarter of this 
year.  Commercial loans, including real estate loans, were 
up $253.3 million, or 1.7%, from December 31, 1998 levels. 
Residential mortgages continue to decline, down $74.3 
million, as normal amortization and prepayments reduce 
outstandings while new originations are held as an available
for sale asset. 

  Investment securities declined by $416.7 million during
the quarter to $5.94 billion as of March 31, 1999.  Scheduled 
maturities of the investment securities were used to fund in 
part the increase in loans during the quarter.  At March 31,
1999  the net unrealized gain on available for sale securities
was $118.2 million and the related after tax increase to 
shareholders' equity was $75.9 million.  Mortgage loans 
held for sale were $1.18 billion at March 31, 1999, a 
reduction from the $1.54 billion level at December 31, 1998. 
					-16-

  Total deposits were $27.87 billion at March 31, 1999, a 
reduction of $983.0 million, or 3.4%, from the December 31,
1998 level.  Demand deposit balances declined by $666.3 
million to $5.98 billion at March 31, 1999 reflecting, in 
part, the tendency of commercial customers to maintain 
higher cash balances at year ends.  Interest bearing 
deposits decreased by $316.7 million, or 1.4%, from year 
end levels.  The shift in deposit preferences continues 
with reductions in savings, NOW accounts, and small 
CDs, collectively down by $425.7 million,  being partially 
offset by the $150.2 million increase in money market 
accounts.  Retail deposit customers are seeking higher 
yields in deposit accounts and alternative investment 
vehicles thus limiting Firstar's ability to maintain or 
increase deposits.  Short-term borrowed funds increased 
by $270.4 million, or 7.4%, during the quarter to a level 
of $3.91 billion.  Increased usage of this funding source 
was necessary to replace the reduced levels of deposits. 

Results of Operations

  Net interest income, Firstar's principal source of 
revenue, increased by $27.1 million, or 7.8% on a tax 
equivalent basis compared to the first quarter of 1998.  
The increase was due to higher average earning asset 
balances partially offset by a slightly reduced net 
interest margin.  Average earning assets were up $2.67 
billion, or 8.6% over the first quarter of 1998.  
Average retail loans increased by $862 million, or 12.7%, 
while commercial loans rose by $1.93 billion, or 14.6%.  
Average loans held for sale more than doubled due to 
both the acquisition of a mortgage banking business 
in the first quarter of last year and increased market
activity this year.  

  The net interest margin decreased by two basis points 
to 4.49% in the first quarter of 1999 compared to the 
first quarter of 1998.  The yield on total earning assets 
declined by 46 basis points to 7.90% in the current 
quarter.  The yield on total loans decreased by 58 
basis points reflecting generally market driven forces.  
The rate paid on interest bearing liabilities declined 
by 54 basis points similarly reflecting lower market 
rates.  Interest spread, the difference between the rate 
on total earning assets and the rate on interest bearing 
liabilities increased by eight basis points. The 
contribution of interest free funds to net interest 
margin declined, however, by ten basis points producing 
the net reduction in margin of two basis points.  The 
contribution of interest free funds was lessened by the 
absolute reduction in interest rate levels along with a 
higher proportion of earning assets funded by interest 
bearing liabilities.  Table 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 rates,  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 rates, and changes in 
the mix and levels of balance sheet accounts.  
The most recent simulation projected the impact 
of a 300 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 1.0% from 
a base case, while an increasing rate scenario 
would decrease net interest revenue by 1.3%.

  The loan loss provision charged to earnings 
increased by $7.3 million to $35.9 million in the
first quarter of 1999 from the first quarter of 1998
due in part to slightly higher charge-offs.  Net loan
charge-offs were $29.9 million in the first quarter
of 1999 compared to $27.0 a year earlier.  
Additionally, loan growth during the period
required an increased loan loss reserve to maintain 
adequate reserve levels.

  Noninterest income is a growing source of revenue 
for Firstar, representing 37.2% of tax equivalent net 
revenue in the first quarter of 1999, up from 36.1% 
in the same period of last year. Noninterest income 
increased by $26.0 million, or 13.2%, to a level of 
$223.1 million in the first quarter of 1999.   Trust 
income increased $9.6 million, or 15.3%, due to new 
business in all product lines and market segments as 
well as higher stock market values.  Additionally,  
first quarter trust income benefited from the transfer 
of Firstar sponsored Stellar Funds to in-house processing.  
Mortgage banking revenue was up slightly by 1.1% with 
higher servicing income and origination gains being 
offset by increased amortization of servicing rights 
and a lower level of gains realized on the sale 
of servicing rights.  Corporate cash management 
income increased $3.0 million, or 14.9%, due to new 
business development, an expanded product line and 
higher customer transaction volumes.  Credit card 
revenue rose $3.6 million, or 19.8%, due to an expanded
customer base, increased merchant activity and card 
usage. Brokerage revenue declined as a result of the 
outsourcing of that product to a third party broker.  
All other income increased by $5.9 million, or 31.5%,  
and included leasing related revenues from a recently 
acquired leasing company.  Table 2 shows the components
of noninterest income. 

  Noninterest expense, excluding merger related expenses, 
totaled $285.2 million, a decrease of $15.2 million, or 5.1%, 
from the first quarter of 1998.  Staff expense for the first 
quarter decreased $16.8 million, 10.8%.  This decrease resulted 
primarily from staff reductions in support and back room 
operations as a result of recently completed mergers.  In 
addition, staff expenses were reduced through  new deferrals 
of loan origination costs and the outsourcing of the brokerage 
business.  Offsetting these decreases somewhat were normal 
salary increases and staff additions for new branches.  
Fringe benefits also declined as result of merging the 
separate companies' plans.

  Equipment expense declined by $1.6 million, or 6.9%, due 
to savings resulting from the merger.  Occupancy expense 
increased $1.9 million, or 7.6%, due to both the opening of 
new branches and acquisitions.  Amortization of intangible 
assets increased $4.7 million, or 41.5%, due to new 
acquisitions.  All other operating expenses declined an 
aggregate $3.4 million, or

3.9%, reflecting various cost saving initiatives.  Table 3 
shows the components of noninterest expenses.

  Before merger related costs, Firstar's efficiency ratio 
was 47.60% in the first quarter of 1999, a significant 
improvement over the 55.02% of the first quarter of last year.  

Asset Quality 

  As of March 31,1999, the allowance for loan losses was $401.9 
million, or 1.53% of loans outstanding compared to 1.53% at 
December 31, 1998 and 1.60% a  year earlier.  The decrease from 
the prior year resulted from a change in the management of 
problem loans as a result of the merger. A more aggressive charge-
off policy has been adopted.  The allowance as a percentage of 
nonperforming loans was 330% at March 31, 1999 compared to 318% 
at December 31, 1998 and 317% a year earlier. Table 4 provides a 
summary of activity in the allowance for loan losses by type of 
loan.  Net charge-offs totaled $29.9 million in the first quarter 
of 1999 compared with $27.0 million in the same period of last 
year.  Annualized net charge-offs as a percent of average loans 
remained essentially level from period to period.  Credit card 
net charge-offs increased from 4.52% of average outstandings in
the first quarter of 1998 to 5.19% in the current quarter.  Lower
charge-off levels in other retail lending and in commercial loans 
partially offset the increase in credit card losses.  Other retail 
lending net charge-offs declined from .54% of average outstandings 
in the first quarter on 1998 to .29% in the current quarter, while 
commercial loans charge-offs declined from .34% to .31%.

  Nonperforming assets, as shown in Tables 5 and 6, were $136.7
million at March 31, 1999.  This level is unchanged from 
December 31, 1998 and down slightly from a year earlier.  
Measured as a percent of loans and other real estate, 
nonperforming assets have declined from .56% at March 31, 1998
to .52% on March 31, 1999.  Nonperforming loans are currently 
at historically low levels and it can be expected that they 
may increase in future periods.

Capital Resources 
 
  Total shareholders' equity was $3.68 billion at March 31, 
1999, an increase of $148.3 million from December 31, 1998 
and $361.2 million from a year earlier.  The ratio of  
shareholders' equity to assets was 9.69% at March 31, 1999,
compared to 9.17% at December 31, 1998 and 9.11% at March 
31, 1998.  

  Banking industry regulators define minimum capital 
requirements for bank holding companies.  Firstar's tier 1
and total risk-based capital ratios as of March 31, 1999
amounted to 9.29% and 11.29%, respectively, well above the
minimum requirements of 4.00%  for tier 1 and 8.00% for 
total risk-based capital.  This compares to tier 1 and 
total risk-based capital ratios of 8.92% and 11.01% at 
December 31, 1998.  Regulatory authorities have also 
established a

minimum leverage ratio of 3.00%, which is defined as 
tier 1 equity to average quarterly assets.  At March
31, 1999, Firstar's leverage ratio was 8.07%, 
compared to 7.52% at December 31, 1998.

  In March 1999, the Board of Directors approved a 
three-for-one stock split and a stock buyback plan.  
The stock split was completed on April 15, 1999 to all 
shareholders of record on March 31, 1999.  All stock 
and per share amounts included in these financial 
statements have been restated to reflect the split.  
The stock buyback program authorizes the repurchase 
of up to fifteen million shares periodically over 
the next two years.  The repurchased shares will be 
held as treasury shares for reissue for various 
corporate purposes, including stock option plans.  
Through March 31, 1999, 793,800 shares have been 
repurchased.



Year 2000
 
  Firstar's Year 2000 ("Y2K") project is directed by 
a committee that provides direct oversight of the Y2K 
initiative.  Firstar has completed its assessment 
of Y2K issues, developed a plan, and arranged resources 
to complete the necessary remediation efforts.  Firstar 
is utilizing both internal and external resources to 
reprogram, or replace, and test the software and 
hardware for Y2K modifications.  Currently Firstar 
has remediated and tested 99% of its mission critical 
applications.  The remaining significant applications 
are expected to be completed by June 30, 1999.  A 
separate test environment has been established to 
accommodate testing activity  and the anticipated need 
to test with customers and other third parties during 
the remainder of the year.

  Firstar relies on several third party service 
providers for key business processes and works closely
to monitor their Y2K efforts.  Firstar has obtained written 
and verbal verification from significant third party 
service providers and vendors of their Y2K readiness.  
While Firstar continues to discuss, obtain written 
certification from, and test the systems of critical 
vendors and third party service providers as to Y2K 
compliance, no assurance exists that any impact associated 
with incompatible systems after December 31, 1999 will 
not have a material adverse effect on Firstar's business, 
financial condition or results of operations.

  Firstar previously established business continuity 
plans for its various lines of business and is assessing 
these plans for the possible impact of Y2K anticipated 
failures.  Existing business continuity plans will be 
adjusted where appropriate for those scenarios that may 
have the most severe impact on its operations.  This 
activity is expected to be completed by June 30, 1999.

  Major risks associated with the Y2K issue as it applies
 to external parties include, but are not limited to,  
failure of voice and data communications systems due to 
loss of satellites or problems at communication companies; 
ATM shutdowns; non-availability or delays in cash

					-25-

couriers/shipments; failure of government systems; and 
shutdown of government facilities or power companies.  
Major risks associated with internal systems include, 
but are not limited to, inability to complete transactions 
or properly process customer data; inability to process 
electronic transactions; failure of time locks or security
systems and inability to meet customer demands for cash.

  The costs of the Y2K project are primarily staff related 
and are expensed as incurred.  Currently, Firstar estimates 
that the total cost of the Y2K project will be approximately
$32 million of which $5 million was expensed in 1997; $18 
million in 1998; and $3 million in the first quarter of 1999.





  This discussion may contain forward looking statements 
with respect to the financial condition, results of 
operations and business of Firstar.  These forward looking 
statements involve certain risks and uncertainties.  
Factors that may cause actual results to differ materially 
from those contemplated  include among other things, the 
following possibilities: (i)expected cost savings from 
recent acquisitions cannot be fully realized or realized 
within the expected time; (ii)revenues are lower than 
expected; (iii)competitive pressure among depository 
institutions increases significantly; (iv)changes in the 
interest rate environment reduces interest margins; 
(v)general economic conditions are less favorable than 
expected; and (vi)legislation or regulatory requirements 
adversely affect the business that Firstar is engaged in.

Item 5. Other Information

Unaudited Pro Forma Condensed Combined Financial Information

  The following unaudited Pro Forma Condensed Combined
Financial Information and Notes are presented to show the
impact on the historical financial position and the 
results of operations of the combined company for the 
proposed merger of Firstar Corporation and Mercantile 
Bancorporation Inc.  This pro forma information should 
be read in conjunction with the consolidated financial 
statements, including notes thereto, of  Firstar 
Corporation and Mercantile Bancorporation Inc. The 
unaudited Pro Forma Condensed Combined Financial 
Information is presented for illustration purposes only 
in accordance with the assumptions set forth below, and 
is not necessarily indicative of the operating reults or 
financial position that would have occurred if the merger 
had been consummated nor is it necessarily indicative of 
future operating results or financial position of the 
combined company.

  The unaudited Pro Forma Condensed Combined Balance Sheet 
as March 31, 1999 combines the historical consolidated 
balance sheets of Firstar Corporation and Mercantile 
Bancorporation Inc, as if the merger had been effective 
on that date.  The unaudited Pro Forma Condensed Combined 
Income Statements for the quarter ended March 31, 1999 and 
the years ended December 31, 1998, 1997 and 1996 present 
the combined results of operations of Firstar Corporation 
and Mercantile Bancorporation Inc. as if the merger had 
been effective at January 1, 1996.   This pro forma 
financial information reflects the application of the 
pooling of interests method of accounting for the merger.  
Under this method of accounting, the recorded asset, 
liabilities, shareholders' equity, income and expenses 
of both companies are combined and reflected at their 
historical amounts.

  The combined company expects to achieve substantial 
merger benefits including operating cost savings. 
The pro forma earnings do not reflect any financial 
benefits which are expected to result from the 
consolidation of operations and are not indicative of 
the results of future operations.  No assurances can 
be given with respect to the ultimate level of 
financial benefits to be realized.

Firstar Corporation/Mercantile Bancorporation Inc.
Notes to the Unaudited Pro Forma
Condensed Combined Financial Information


Note 1 -  Basis of Presentation
	
  On April 30, 1999 Firstar Corporation announced that 
it had signed a definitive agreement to acquire Mercantile 
Bancorporation Inc. through an exchange of shares.  

  The unaudited Pro Forma Condensed Combined Financial 
Information has been prepared assuming that the merger will 
be accounted for under the pooling of interests method 
and is based on the historical consolidated financial 
statements of the two companies.  A review of each company's 
respective accounting policies has not been completed.  As a 
result of this review, it might be necessary to restate 
certain amounts in the financial statements of the combined 
company to conform to those accounting policies that are most 
appropriate.  Any such restatements are not expected to be 
material.

Note 2 - Shareholders' Equity

  Under the terms of the agreement, Mercantile shareholders 
will receive 2.091 shares of Firstar common stock for each 
share of Mercantile common stock owned.  Mercantile had 
157,869,000 shares of common stock outstanding at March 31, 
1999 which will be exchanged for approximately  330,104,000 
shares of Firstar common stock.  The combined company will 
have approximately 991,318,000 shares outstanding after the 
merger.  The common stock in the unaudited Pro Forma 
Condensed Combined Balance Sheet has been adjusted to 
reflect the par value amount of shares of the combined 
company.  Pro Forma retained earnings reflects an adjustment 
for estimated merger related charges as described in 
Note 3 below.

Note 3 - Merger Related Charges

  In connection with the merger, Firstar and Mercantile 
expect the combined company to incur pre-tax merge
related charges of approximately $428 million.  The
are expected to include approximately $159 million in
employee related payments, $94 million in direct 
conversion costs, $60 million in charges related to 
consolidation of systems and operations, $24 million in 
occupancy and equipment charges (elimination of duplicate 
facilities and write-off of equipment) and $91 million 
in other merger related costs ( including legal and 
investment banking fees).	

The merger related charges and related tax effect have 
been reflected in the unaudited Pro Forma Condensed 
Combined Balance Sheet as of March 31, 1999, and have not 
been reflected in the unaudited Pro Forma Condensed 
Combined Income Statements as they are not expected to 
have a continuing impact on the operations of the 
combined company.
