                  on Form S-4, No. 333-64099, under the Securities Act of 1933
                  (which includes or incorporates by reference pro forma

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         The validity of the Firstar Common Stock offered hereby has been passed
upon for the Registrant by Jennie P. Carlson, Esq., Senior Vice President,
General Counsel and Secretary of the Registrant. Ms. Carlson beneficially owns
18,627 shares of the Common Stock of the Registrant.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Pursuant to the provisions of Sections 180.0850 through 180.0859,
inclusive, of the Wisconsin Business Corporation Law, directors and officers are
entitled to mandatory indemnification from the Registrant against certain
liabilities and expenses (i) to the extent such officers or directors are
successful in the defense of a proceeding; and (ii) in proceedings in which the
director or officer is not successful in defense thereof, unless it is
determined that the director or officer breached or failed to perform his or her
duties to the Registrant and such breach or failure constituted: (a) a willful
failure to deal fairly with the Registrant or its shareholders in connection
with a matter in which the director or officer had a material conflict of
interest; (b) a violation of the criminal law unless the director or officer had
reasonable cause to believe his or her conduct was lawful or had


                                      II-1

   4



no reasonable cause to believe his or her conduct was unlawful; (c) a
transaction from which the director or officer derived an improper personal
profit; or (d) willful misconduct. Additionally, under Section 180.0828 of the
Wisconsin Business Corporation Law, directors of the Registrant are not subject
to personal liability to the Registrant, its shareholders or any person
asserting rights on behalf thereof for certain breaches or failures to perform
any duty resulting solely from their status as directors, except in
circumstances paralleling those outlined above.

         The Registrant's By-Laws contain similar indemnification provisions as
to its directors and officers.

         Expenses for the defense of any action for which indemnification may be
available may be advanced by the Registrant under certain circumstances.

         The Registrant intends to maintain a liability insurance policy for
officers and directors.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 8.  EXHIBITS.

         The following Exhibits are filed as part of this Registration
Statement.

         Exhibit No.
         -----------

          5.1              Opinion of Counsel
         23.1              Consent of KPMG Peat Marwick LLP
         23.2              Consent of Arthur Andersen LLP
         23.3              Consent of Counsel (included in Exhibit 5)
         24                Power of Attorney

         The Registrant undertakes that it will submit or has submitted the Plan
and any amendment thereto to the Internal Revenue Service ("IRS") in a timely
manner and has made or will make all changes required by the IRS in order to
qualify the Plan.

ITEM 9.  UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

         *(a) (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement:

                  (i) to include any prospectus required by section 10(a)(3) of
the Securities Act of 1933;

                  (ii) to reflect in the prospectus any facts or events arising
after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the Registration
Statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate

                                      II-2

   5



offering price set forth in the "Calculation of Registration Fee" table in the
effective Registration Statement;

                  (iii) to include any material information with respect to the
plan of distribution not previously disclosed in the Registration Statement or
any material change to such information in the Registration Statement;

         Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the information required to be included in a post-effective amendment
by those paragraphs is contained in periodic reports filed by the Registrant
pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the Registration Statement.

                  (2) That, for the purpose of determining any liability under
the Securities Act of 1933, each such post-effective amendment shall be deemed
to be a new Registration Statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         *(b) That, for purposes of determining any liability under the
Securities Act of 1933, each filing of the Registrant's annual report pursuant
to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in the Registration Statement shall be deemed to be a
new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         *(h) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
