                              [US BANCORP LOGO(R)]
               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
                                  U.S. BANCORP

     The merger transaction between the former U.S. Bancorp ("old U.S. Bancorp")
and Firstar Corporation ("Firstar") was completed on February 27, 2001, with the
combined company retaining the U.S. Bancorp name (hereinafter referred to as
"U.S. Bancorp"). Shareholders of the old U.S. Bancorp received 1.265 shares of
common stock of U.S. Bancorp for each share of old U.S. Bancorp stock they held
and Firstar shareholders received one share of common stock of U.S. Bancorp for
each share of Firstar stock they held.

     The unaudited pro forma combined selected financial data of U.S. Bancorp
for the most recent five years ended December 31, 2000 is shown on page 2. Pages
3 through 7 present the unaudited pro forma combined financial information and
explanatory notes of U.S. Bancorp as of December 31, 2000 and for the years
ended December 31, 2000, 1999 and 1998. The unaudited pro forma combined
selected financial data, financial information and explanatory notes are
presented to show the impact of the merger on U.S. Bancorp's historical
financial positions and results of operations under the pooling-of-interests
method of accounting. Under this method, the recorded assets, liabilities,
shareholders' equity, income and expenses of both companies are combined and
reflected at their historical amounts. The unaudited pro forma combined selected
financial data of U.S. Bancorp gives effect to the merger as if the merger had
been consummated at the beginning of the earliest period presented. The
unaudited pro forma combined balance sheet of U.S. Bancorp as of December 31,
2000 assumes the merger was consummated on that date. The unaudited pro forma
combined statements of income of U.S. Bancorp give effect to the merger as if
the merger had been consummated at the beginning of the earliest period
presented.

     The unaudited pro forma combined balance sheet of U.S. Bancorp as of
December 31, 2000 reflects the effect of an estimated non-recurring pre-tax
merger related charge of $800 million, as the underlying plans and actions have
been substantially finalized. See note 3 on page 7 for additional information
regarding this item. U.S. Bancorp presents net income, and the corresponding per
share calculations, excluding merger charges and other nonrecurring items
("adjusted net income") in order to enhance the understanding and assessment of
results of operations by highlighting net income attributable to normal,
recurring operations of the business. Adjusted net income should not be viewed
as a substitute for net income determined in accordance with GAAP. Furthermore,
U.S. Bancorp's definition of "merger related charges and other nonrecurring
items" may differ from that used by other companies. The table below shows net
income, calculated in accordance with GAAP, and the corresponding per share
calculations. It also presents adjusted net income and the corresponding per
share calculations.

     U.S. Bancorp expects to achieve substantial benefits as a result of the
merger, including reduced operating expenses. No assurances can be given with
respect to the ultimate level of financial benefits to be realized, if any. The
combined pro forma earnings do not reflect anticipated financial expenses or
benefits that may accrue as a result of the merger. The combined pro forma
information is not indicative of the results of future operations, nor does it
necessarily reflect what the historical results of U.S. Bancorp would have been
had Firstar and the old U.S. Bancorp been combined during the periods presented.
The combined pro forma information is based on historical financial information
that has been presented in prior filings of Firstar and the old U.S. Bancorp
with the Securities and Exchange Commission (the "SEC").

* Items in this section have been adjusted for merger related charges,
  restructuring charges and the one-time SAIF assessment in 1996. The
  presentation of adjusted net income and related ratios, excluding "merger
  related charges and other nonrecurring items" as determined by Firstar and the
  old U.S. Bancorp, is intended to enhance the understanding and assessment of
  results of operations by highlighting net income attributable to normal,
  recurring operations of the business. Adjusted net income should not be viewed
  as a substitute for net income determined in accordance with GAAP.
  Furthermore, Firstar's and the old U.S. Bancorp's definition of "merger
  related charges and other nonrecurring items" may differ from that used by
  other companies.

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

NOTE 1 -- BASIS OF PRESENTATION

     The merger transaction between the former U.S. Bancorp ("old U.S. Bancorp")
and Firstar Corporation ("Firstar") was completed on February 27, 2001, with
combined company retaining the U.S. Bancorp name (hereinafter referred to as
"U.S. Bancorp").

     The unaudited pro forma combined financial information of U.S. Bancorp has
been prepared under the pooling-of-interests method of accounting and is based
on the historical consolidated financial statements of the two companies. A
review of each company's respective accounting policies is being completed. As a
result of this review, it will be necessary to restate certain amounts in the
financial statements of U.S. Bancorp to conform to those accounting policies
that will be followed. Any such restatements are not expected to be material,
and therefore are not reflected in the unaudited pro forma combined financial
information of U.S. Bancorp.

NOTE 2 -- SHAREHOLDER'S EQUITY

     Under the terms of the merger agreement, Firstar shareholders received one
share, and the old U.S. Bancorp shareholders 1.265 shares, of common stock of
U.S. Bancorp for each share of Firstar and old U.S. Bancorp common stock, held
at February 27, 2001, respectively. Old U.S. Bancorp had 752,921,723 shares of
common stock outstanding at February 27, 2001, which was exchanged for
approximately 952,445,980 shares of U.S. Bancorp's common stock. U.S. Bancorp
currently has approximately 1,904,056,390 shares outstanding.

     The common stock line item in the unaudited pro forma combined balance
sheet of U.S. Bancorp has been adjusted to reflect the fact that, in connection
with the merger, the par value of shares of U.S. Bancorp was reduced from $1.25
per share to $0.01 per share.

     The pro forma treasury stock adjustment reflects the cancellation of shares
held by Firstar, the old U.S. Bancorp or any of their wholly-owned subsidiaries
(except for shares held in trust accounts, managed accounts and the like, or
otherwise held in a fiduciary capacity that are beneficially owned by third
parties (trust account shares) or shares held by Firstar or the old U.S. Bancorp
or any of their subsidiaries in respect of a debt previously contracted (DPC
shares)).

NOTE 3 -- MERGER RELATED CHARGES

     In connection with the merger, management estimates U.S. Bancorp will incur
pre-tax merger related charges of approximately $800 to $900 million. These are
currently estimated to include $186 million in employee related costs, $312
million for conversions of systems and consolidation of operations, $103 million
in occupancy and equipment charges (elimination of duplicate facilities and
write-off of equipment) and $199 million in other merger related costs
(including investment banking fees, legal, balance sheet restructuring charges
and other costs). The remaining $100 million of merger related charges
(primarily conversion of systems and consolidation of operations costs) that may
be incurred will be evaluated by management on a cost/benefit analysis basis.
These merger related costs may be incurred if future cost savings or future
revenue enhancements can be derived.

     Estimated pre-tax merger related charges of $800 million have been
reflected in the unaudited pro forma combined balance sheet of U.S. Bancorp as
of December 31, 2000, as the underlying plan and actions have been finalized.
However, they are not reflected in the unaudited pro forma combined income
statements of U.S. Bancorp as they are not expected to have a continuing impact
on the operations of U.S. Bancorp.

     The estimated pre-tax merger related charge, in connection with this
merger, to be included in the first quarter ending March 31, 2001 is $500
million. This charge includes approximately $180 million of employee related
costs, $9 million of occupancy and equipment charges, $48 million of conversion
costs and $263 million of other merger related charges. It is anticipated that
gains to be recognized in future quarters related to certain divestitures made
in connection with the merger will reduce the other merger related costs to the
estimated $199 million.
