                              W I T N E S S E T H:

                  WHEREAS, the Boards of Directors of Star, Firstar and Foxtrot

to the terms and conditions set forth herein, merge with and into Foxtrot (DE)
(the "Second Step Merger" and, together with the Reincorporation Merger, the

                  WHEREAS, it is the intent of the respective Boards of
Directors of Star and Firstar that the Merger be structured as a "merger of

                  WHEREAS, as a condition to, and simultaneously with the

                  WHEREAS, the parties desire to provide for certain conditions,

                                    ARTICLE I

                           THE REINCORPORATION MERGER

                   Section 1.1. The Reincorporation Merger. Subject to the terms
and conditions of this Agreement, Firstar shall be merged with and into Foxtrot
(DE) in accordance with the Wisconsin Business Corporation Law (the "WBCL") and
the Delaware General Corporation Law ("DGCL") and the separate corporate
existence of Firstar shall cease. Foxtrot (DE) shall be the surviving
corporation of the Reincorporation Merger, shall continue its corporate
existence under the name "Firstar Corporation" and shall be governed by the laws
of the State of Delaware.

                   Section 1.2. First Effective Time. The Reincorporation Merger
shall become effective on the date and at the time (the "First Effective Time")
specified in the appropriate documents in respect of the Reincorporation Merger
which are filed with the Secretary of State of the State of Delaware and the
Department of Financial Institutions of the State of Wisconsin in such form as
required by, and in accordance with, the relevant provisions of the DGCL and the
WBCL. The First Effective Time shall occur on the same date and immediately
prior to the Effective Time as specified in Section 2.2.

                   Section 1.3. Effects of the Reincorporation Merger. At and
after the First Effective Time, the Reincorporation Merger shall have the
effects set forth in Sections 259 and 261 of the DGCL and Section 180.1107 of
the WBCL.

                   Section 1.4. Conversion of Securities. (a) At the First
Effective Time, by virtue of the Reincorporation Merger and without any action
on the part of Star, Firstar, Foxtrot (DE) or the holders of any capital stock
of Firstar, Star or Foxtrot (DE), each share of the common stock, par value
$1.25, of Firstar ("Firstar Common Stock") issued and outstanding immediately
prior to the First Effective Time shall cease to be outstanding and (other than
any shares of Firstar Common Stock held by Firstar or any of its wholly owned
Subsidiaries (as defined herein), except for Trust Account Shares (as defined
herein) and DPC Shares (as defined herein)), shall be converted into the right
to receive 0.76 (the "Exchange Ratio") shares of Foxtrot (DE) Common Stock (as
defined herein).

                   (b) All of the shares of Firstar Common Stock converted
into the right to receive Foxtrot (DE) Common Stock pursuant to this Article I
shall no longer be outstanding and shall automatically be cancelled and shall
cease to exist as of the First Effective Time, and each certificate (each a
"Firstar Common Certificate") previously representing any such shares of Firstar
Common Stock shall thereafter represent only the right to receive (i) a
certificate representing the number of whole shares of Foxtrot (DE) Common Stock
and (ii) cash in lieu of any fractional shares otherwise issuable pursuant to
Section 1.4(a), in accordance with Section 3.2. Firstar Common Certificates
previously representing shares of Firstar Common Stock shall be exchanged for
certificates representing whole shares of Foxtrot (DE) Common Stock and cash in
lieu of fractional shares issued in consideration therefor upon the surrender of
such Firstar Common Certificates in accordance with Section 3.1 without any
interest thereon.

                   (c) At the First Effective Time, all shares of Firstar
Common Stock that are owned by Firstar as treasury stock and all shares of
Firstar Common Stock that are owned, directly or indirectly, by Firstar or any
of its wholly owned Subsidiaries (other than Trust Account Shares and DPC
Shares) shall be cancelled and shall cease to exist and no stock of Foxtrot (DE)
or other consideration shall be delivered in exchange therefor.

                   Section 1.5. Foxtrot (DE) Common Stock. At and after the
First Effective Time, each share of Foxtrot (DE) Common Stock issued and
outstanding immediately prior to the First Effective Time shall be cancelled and
retired and shall resume the status of authorized and unissued shares of Foxtrot
(DE) Common Stock, and no shares of Foxtrot (DE) Common Stock or other
securities of Foxtrot (DE) shall be issued in respect thereof.

                   Section 1.6. Options. Firstar shall take action to amend the
Firstar Stock Plans (as defined herein) so that, at the Effective Time, each
option granted by Firstar to purchase shares of Firstar Common Stock which is
outstanding and unexercised immediately prior thereto shall cease to represent a
right to acquire shares of Firstar Common Stock and shall be converted
automatically into an option to purchase shares of Foxtrot (DE) Common Stock in
an amount and at an exercise price determined as follows (and otherwise subject
to the terms of the appropriate Firstar Benefit Plan (as defined herein)
pursuant to which such options have been granted (such plans collectively the
"Firstar Stock Plans") and the agreements evidencing grants thereunder): (i) the
number of shares of Foxtrot (DE) Common Stock to be subject to the new option
shall be equal to the product of the number of shares of Firstar Common Stock
subject to the original option and the Exchange Ratio, provided that any
fractional shares of Foxtrot (DE) Common Stock resulting from such
multiplication shall be rounded down to the nearest whole share and (ii) the
exercise price per share of Foxtrot (DE) Common Stock under the new option shall
be equal to the exercise price per share of Firstar Common Stock under the
original option divided by the Exchange Ratio, provided that such exercise price
shall be rounded down to the nearest whole cent. The adjustment provided herein
with respect to any options which are "incentive stock options" (as defined in
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code")) shall
be and is intended to be effected in a manner which is consistent with Section
424(a) of the Code. The duration and other terms of the new option shall be the
same as the original option except that all references to Firstar shall be
deemed to be references to Foxtrot (DE).

                   Section 1.7. Certificate of Incorporation. Subject to the
terms and conditions of this Agreement, at the First Effective Time, the
Certificate of Incorporation of Foxtrot (DE) shall be substantially in the form

hereto as Exhibit D, with such changes thereto as shall be mutually agreed upon
by Star and Firstar, until thereafter amended in accordance with applicable law.

                   Section 2.2. Effective Time. The Second Step Merger shall
become effective as set forth in the certificate of merger (the "Certificate of
Merger") which shall be filed with the Secretary of State of the State of
Delaware and the Secretary of State of the State of Ohio on the Closing Date (as
defined herein). The term "Effective Time" shall be the date and time when the
Second Step Merger becomes effective, as set forth in the Certificate of Merger.
Subject to the terms and conditions of this Agreement, the Effective Time shall

Foxtrot (DE) , each share of the common stock, par value $5.00 per share, of
Star (the "Star Common Stock") issued and outstanding immediately prior to the
Effective Time (other than Dissenting Shares (as defined herein) and shares of
Star Common Stock held in Star's treasury or directly or indirectly by Star or
any of its wholly owned Subsidiaries or Foxtrot (DE) (except for Trust Account

(the "Second Merger Exchange Ratio") of the common stock, par value $0.01, of
Foxtrot (DE) (the "Foxtrot (DE) Common Stock").

<PAGE>
                   (b) All of the shares of Star Common Stock converted
into the right to receive Foxtrot (DE) Common Stock pursuant to this Article II
shall no longer be outstanding and shall automatically be cancelled and shall
cease to exist as of the Effective Time, and each certificate (each a "Star
Common Certificate") previously representing any such shares of Star Common
Stock shall thereafter represent only the right to receive (i) a certificate
representing the number of whole shares of Foxtrot (DE) Common Stock and (ii)
cash in lieu of any fractional shares otherwise issuable pursuant to Section
2.4(a), in accordance with Section 3.2. Star Common Certificates previously
representing shares of Star Common Stock shall be exchanged for certificates
representing whole shares of Foxtrot (DE) Common Stock and cash in lieu of
fractional shares issued in consideration therefor upon the surrender of such
Star Common Certificates in accordance with Section 3.1 without any interest
thereon.

                   (c) At the Effective Time, all shares of Star Common
Stock that are owned by Star as treasury stock and all shares of Star Common
Stock that are owned, directly or indirectly, by Star or any of its wholly owned
Subsidiaries or Foxtrot (DE) (other than shares of Star Common Stock held,
directly or indirectly, in trust accounts, managed accounts and the like or
otherwise held in a fiduciary capacity that are beneficially owned by third
parties (any such shares, and shares of Firstar Common Stock which are similarly
held, whether held directly or indirectly by Star, Foxtrot (DE) or Firstar, as
the case may be, or any of their respective Subsidiaries being referred to
herein as "Trust Account Shares") and other than any shares of Star Common Stock
held by Star or Firstar or any of their respective Subsidiaries or Foxtrot (DE)
in respect of a debt previously contracted (any such shares of Star Common Stock
and shares of Firstar Common Stock which are similarly held, whether held
directly or indirectly by Star, Foxtrot (DE) or Firstar, as the case may be, or
any of their respective Subsidiaries, being referred to herein as "DPC Shares"))
shall be cancelled and shall cease to exist and no stock of Foxtrot (DE) or
other consideration shall be delivered in exchange therefor.

                   Section 2.5. Dissenting Shares. Notwithstanding anything in
this Agreement to the contrary, shares of Star Common Stock which are
outstanding immediately prior to the Effective Time and with respect to which
dissenters' rights shall have been properly demanded in accordance with Section
1701.85 of the OGCL ("Dissenting Shares") shall not be converted into the right
to receive Foxtrot (DE) Common Stock; instead, the holders thereof shall be
entitled to payment of the appraised value of such Dissenting Shares in
accordance with the provisions of Section 1701.85 of the OGCL; provided,
however, that (i) if any holder of Dissenting Shares shall subsequently deliver
a written withdrawal of his demand for appraisal of such shares, or (ii) if any
holder fails to establish his entitlement to dissenters' rights as provided in
Section 1701.85 of the OGCL, such holder or holders (as the case may be) shall
forfeit the right to appraisal of such shares of Star Common Stock and each of
such shares shall thereupon be deemed to have been converted into the right to
receive, and to have become exchangeable for, as of the Effective Time, Foxtrot
(DE) Common Stock, as provided in Section 2.4(a) hereof.

                   Section 2.6. Options. Star shall take action to amend the
Star Stock Plans (as defined herein) so that, at the First Effective Time, each
option granted by Star to purchase shares of Star Common Stock which is
outstanding and unexercised immediately prior thereto shall cease to represent a
right to acquire shares of Star Common Stock and shall be converted
auto-

                                      -5-
<PAGE>

matically into an option to purchase a number of shares of Foxtrot (DE) Common
Stock equal to the number of shares of Star Common Stock subject to such option
immediately prior to the First Effective Time at an exercise price per share of
Foxtrot (DE) Common Stock equal to the exercise price per share of Star Common
Stock in effect immediately prior to the Effective Time and otherwise subject to
the terms of the appropriate Star Benefit Plans pursuant to which such options
have been granted (such plans collectively the "Star Stock Plans") and the
agreements evidencing grants thereunder. The adjustment provided herein with
respect to any options which are "incentive stock options" (as defined in
Section 422 of the Code) shall be and is intended to be effected in a manner
which is consistent with Section 424(a) of the Code. The duration and other
terms of the new option shall be the same as the original option except that all
references to Star shall be deemed to be references to Foxtrot (DE).

                   Section 2.7. Foxtrot (DE) Common Stock. At and after the
Effective Time, each share of Foxtrot (DE) Common Stock issued and outstanding
immediately prior to the Effective Time shall remain an issued and outstanding
share of common stock of the Surviving Corporation and shall not be affected by
the Second Step Merger.

                   Section 2.8. Certificate of Incorporation. Subject to the
terms and conditions of this Agreement, at the Effective Time, the Certificate
of Incorporation of the Surviving Corporation shall be the Certificate of
Incorporation of Foxtrot (DE), until thereafter amended in accordance with
applicable law.

                   Section 2.9. By-Laws. Subject to the terms and conditions of

Time, Roger L. Fitzsimonds shall be Chairman of the Board of the Surviving

Effective Time, until duly changed in compliance with applicable law and the

of Directors of the Surviving Corporation shall be the Board of Directors of
Foxtrot (DE) as specified in Section 1.9. The majority of the meetings of the
Board of Directors of the Surviving Corporation in any calendar year shall be
held in Milwaukee, Wisconsin.

                   (b) Firstar shall cause all requisite action to be taken
so that, at the Effective Time, directors of the Surviving Corporation elected
pursuant to Section 1.9 at the designation of Star and Firstar shall be
represented in proportion to the aggregate representation set forth in Section
1.9 on all committees of the Board of Directors of the Surviving Corporation,
except that seven designees of Star and five designees of Firstar shall be

                   Section 2.13. Tax and Accounting Consequences. It is intended
that the Reincorporation Merger and the Second Step Merger shall each constitute
a reorganization within the meaning of Section 368(a) of the Code, that this
Agreement shall constitute a "plan of reorganization" for the purposes of
Sections 354 and 361 of the Code and that the Merger be accounted for as a

                                   ARTICLE III

                               EXCHANGE OF SHARES

                   Section 3.1. Exchange Procedures. (a) At or prior to the
First Effective Time, the parties shall deposit, or shall cause to be deposited,
with a bank or trust company agreed to by each of Star and Firstar (the
"Exchange Agent"), for the benefit of the holders of Certificates (as defined
herein), for exchange in accordance with this Article III, certificates
representing the shares of Foxtrot (DE) Common Stock, and cash in lieu of any
fractional shares (such cash and certificates for shares of Foxtrot (DE) Common
Stock, together with any dividends or distributions with respect thereto, being
hereinafter referred to as the "Exchange Fund"), to be issued pursuant to
Sections 1.4 and 2.4 and paid pursuant to Section 3.2 in exchange for
outstanding shares of Firstar Common Stock and Star Common Stock. Firstar and
Star shall deliver to Foxtrot (DE) a complete list of their respective
shareholders (including their respective names, addresses and TINs to the extent
reflected in the records maintained by such party or its transfer agent) as of
the record date for the shareholder meetings to be called by the parties as
provided for herein and as of the First Effective Time for Firstar and the
Effective Time for Star, in each case which delivery shall be made as soon as
practicable after the respective date.

                   (b) As soon as practicable after the Effective Time, the
Exchange Agent shall mail to each holder of record immediately prior to the
First Effective Time or the Effective Time, as applicable, of one or more
Firstar Common Certificates or Star Common Certificates (collectively, the
"Certificates") a letter of transmittal (which shall specify that delivery shall
be effected, and risk of loss and title to the Certificates shall pass, only
upon delivery of the Certificates to the Exchange Agent) and instructions for
use in effecting the surrender of the Certificates in exchange for certificates
representing the shares of Foxtrot (DE) Common Stock issuable and any cash in
lieu of fractional shares payable pursuant to this Agreement. Upon proper
surrender of a Certificate for exchange and cancellation to the Exchange Agent,
together with such properly completed letter of transmittal, duly executed, the
holder of such Certificate shall be entitled to receive in exchange therefor, as
applicable, (i) a certificate representing that number of whole shares of
Foxtrot (DE) Common Stock to which such holder of Star Common Stock or Firstar
Common Stock shall have become entitled pursuant to the provisions of Articles I
and II, as ap-

                                      -7-
<PAGE>

plicable, and (ii) a check representing the amount of any cash in lieu of
fractional shares which such holder has the right to receive in respect of the
Certificate surrendered pursuant to the provisions of this Article III and any
dividend or distribution theretofore declared and not yet paid on such shares of
Foxtrot (DE) Common Stock, and the Certificate so surrendered shall forthwith be
cancelled. No interest will be paid or accrued on any cash in lieu of fractional
shares or on any unpaid dividends and distributions payable to holders of
Certificates.

                   (c) If any certificate representing shares of Foxtrot
(DE) Common Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it shall be a
condition of the issuance thereof that the Certificate so surrendered shall be
properly endorsed (or accompanied by an appropriate instrument of transfer) and
otherwise in proper form for transfer, and that the person requesting such
exchange shall pay to the Exchange Agent in advance any transfer or other taxes
required by reason of the issuance of a certificate representing shares of
Foxtrot (DE) Common Stock in any name other than that of the registered holder
of the Certificate surrendered, or required for any other reason, or shall
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not payable. The Surviving Corporation or the Exchange Agent shall accept
Certificates upon compliance with such other reasonable terms and conditions as
the Surviving Corporation or the Exchange Agent may impose to effect an orderly
exchange thereof in accordance with customary exchange practices. Certificates
shall be appropriately endorsed or accompanied by such instruments of transfer
as the Surviving Corporation or the Exchange Agent may require.

                   (d) Any portion of the Exchange Fund, including any
earnings thereon, which remains undistributed to the holders of Certificates for
six months after the Effective Time shall be delivered to the Surviving
Corporation, upon demand, and any holders of Certificates who have not
theretofore complied with this Section 3.1 shall thereafter look only to the
Surviving Corporation for payment of their claim for the consideration provided
for herein and any unpaid dividends and distributions on the Foxtrot (DE) Common
Stock deliverable in respect of such Certificates.

                   (e) After the Effective Time, holders of Certificates
shall cease to have any rights with respect to the stock previously represented
by such Certificates, and their sole rights shall be to exchange such
Certificates for the consideration provided for in this Agreement. After the
Effective Time, there shall be no further transfers on the records of Firstar of
Firstar Common Certificates and no further transfers on the records of Star of
Star Common Certificates, and if such Certificates are presented to Firstar or
Star, as applicable, for transfer, they shall be cancelled against delivery of
the consideration provided therefor in this Agreement. Foxtrot (DE) shall not be
obligated to deliver the consideration to which any former holder of securities
is entitled as a result of the Merger until such holder surrenders the
Certificates as provided herein. No dividends declared on Foxtrot (DE) Common
Stock will be remitted to any holder of Firstar Common Stock or the Star Common
Stock entitled to receive Foxtrot (DE) Common Stock under this Agreement until
such person surrenders the Certificate representing the right to receive such
Foxtrot (DE) Common Stock, at which time such dividends shall be remitted to
such person, without interest and less any taxes that may have been imposed
thereon. Neither the Exchange Agent nor any party to this Agreement nor any
affiliate thereof shall be 

                                      -8-
<PAGE>

liable to any holder of stock represented by any Certificate for any
consideration paid to a public official pursuant to applicable abandoned
property, escheat or similar laws. The Surviving Corporation and the Exchange
Agent shall be entitled to rely upon the stock transfer books of Firstar and
Star to establish the identity of those persons entitled to receive
consideration specified in this Agreement, which books shall be conclusive with
respect thereto. In the event of a dispute with respect to ownership of stock
represented by any Certificate, the Surviving Corporation and the Exchange Agent
shall be entitled to deposit any consideration represented thereby in escrow
with an independent third party and thereafter be relieved with respect to any
claims thereto.

                   (f) In the event any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if reasonably
required by Foxtrot (DE), the posting by such person of a bond in such amount as
Foxtrot (DE) may determine is reasonably necessary as indemnity against any
claim that may be made against it with respect to such Certificate, the Exchange
Agent will issue in exchange for such lost, stolen or destroyed Certificate the
shares of Foxtrot (DE) Common Stock and any cash in lieu of fractional shares
deliverable in respect thereof pursuant to this Agreement.

                   (g) Former holders of record as of the First Effective
Time of shares of Firstar Common Stock and as of the Effective Time of Star
Common Stock shall not be entitled, at and after the First Effective Time and
the Effective Time, respectively, to vote any shares of the Foxtrot (DE) Common
Stock until their Certificates shall have been surrendered in accordance with
this Article III and certificates evidencing such Foxtrot (DE) Common Stock
shall have been issued in exchange therefor.

                   Section 3.2. No Fractional Shares. Notwithstanding any other
provision of this Agreement, neither certificates nor scrip for fractional
shares of Foxtrot (DE) Common Stock shall be issued in the Merger. Each holder
who otherwise would have been entitled to a fraction of a share of Foxtrot (DE)
Common Stock shall receive in lieu thereof cash (without interest) in an amount
determined by multiplying the fractional share interest to which such holder
would otherwise be entitled by the closing sale price of a share of Star Common
Stock on the New York Stock Exchange, Inc. ("NYSE") composite tape on the last
full trading day prior to the Effective Time. No such holder shall be entitled
to dividends, voting rights or any other rights in respect of any fractional
share.

                   Section 3.3. Anti-Dilution Adjustments. If, prior to the
Effective Time, the outstanding shares of Star Common Stock or Firstar Common
Stock shall have been increased, decreased, changed into or exchanged for a
different number or kind of shares or securities as a result of a
reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split, or other similar change in capitalization (other than
solely as a result of the Reincorporation Merger), appropriate adjustment or
adjustments will be made to the Exchange Ratio or the Second Merger Exchange
Ratio, as applicable.

                                   ARTICLE IV

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

                   Section 4.1. Disclosure Schedules. On or prior to the date
hereof, each of Star and Firstar has delivered to the other a schedule
(respectively, its "Disclosure Schedule") setting forth, among other things,
items the disclosure of which is necessary or appropriate in relation to any or
all of its representations and warranties set forth in this Agreement; provided,
that (i) no such item is required to be set forth in a Disclosure Schedule as an
exception to a representation or warranty if its absence is not reasonably
likely to result in the related representation or warranty being deemed untrue
or incorrect under the standard established by Section 4.2, and (ii) the mere
inclusion of an item in a Disclosure Schedule shall not be deemed an admission
by a party that such item represents a material exception or fact, event or
circumstance or that such item would reasonably be expected to result in a
material adverse effect on the financial condition, results of operations or
business of such party and its Subsidiaries taken as a whole, except as may have
resulted or may result from changes to laws and regulations or changes in
economic conditions applicable to banking institutions generally or in general
levels of interest rates affecting banking institutions generally (a "Material
Adverse Effect").

                   Section 4.2. Standard. No representation or warranty of Star
or Firstar contained in Section 4.3 shall be deemed untrue or incorrect, and no
party hereto shall be deemed to have breached any such representation or
warranty, as a consequence of the existence of any fact, circumstance or event
unless such fact, circumstance or event which constitutes a breach of any such
representation or warranty after giving effect to any materiality standards
contained in any representation or warranty, individually or taken together with
all other facts, circumstances or events constituting such breaches, has had or
would reasonably be expected to have a Material Adverse Effect on such party.

                   Section 4.3. Representations and Warranties. Subject to
Sections 4.1 and 4.2 and except as previously disclosed in its Disclosure
Schedule, Firstar hereby represents and warrants to Star, and Star hereby
represents and warrants to Firstar, to the extent applicable, in each case with
respect to itself and its Subsidiaries, as follows:

                   (a) Organization and Authority. Such party and each of
its respective Subsidiaries is a corporation, bank, trust company or other
entity duly organized, validly existing and in good standing under the laws of
the jurisdiction of organization, is duly qualified to do business and is in
good standing in all jurisdictions where its ownership or leasing of property or
the conduct of its business requires it to be so qualified and has corporate
power and authority to own its properties and assets and to carry on its
business as it is now being conducted except, in each case, where the failure to
do so would not either individually or in the aggregate reasonably be expected
to have a Material Adverse Effect on such party. Such party is duly registered
as a bank holding company with the Board of Governors of the Federal Reserve
System (the "Board") under the Bank Holding Company Act of 1956, as amended (the
"Holding Company Act"). True and complete copies of the Articles of
Incorporation and By-laws or Code of Regu-

                                      -10-
<PAGE>

lation as applicable, of such party, each in effect on the date of this
Agreement, have been provided to the other party.

                   (b) Subsidiaries. Such party's Disclosure Schedule sets
forth, among other things, a complete and correct list of all of such party's
direct or indirect subsidiaries (each a "Subsidiary" and collectively the
"Subsidiaries") including such party's banks (the "Banks"), all outstanding
Equity Securities of each of which are owned directly or indirectly by such
party. "Equity Securities" of an issuer means capital stock or other equity
securities of such issuer, options, warrants, scrip, rights to subscribe to,
calls or commitments of any character whatsoever relating to, or securities or
rights convertible into, shares of any capital stock or other Equity Securities
of such issuer, or contracts, commitments, understandings or arrangements by
which such issuer is or may become bound to issue additional shares of its
capital stock or other Equity Securities. All of the outstanding shares of
capital stock of the Subsidiaries of such party are validly issued, fully paid
and nonassessable (subject to Section 180.0622(2)(6) of the WBCL), and those
shares owned by such party are owned free and clear of any lien, claim, charge,
option, encumbrance, agreement, mortgage, pledge, security interest or
restriction (a "Lien") with respect thereto. Except for the Equity Securities of
such party's Subsidiaries and except for Equity Interests held in a fiduciary
capacity, such party does not own beneficially, directly or indirectly, more
than 5% of any class of Equity Securities or similar interests of any
corporation, bank, business trust, association or similar organization. The
Banks of such party are chartered by the Office of the Comptroller of the
Currency. The deposits of the Banks of such party are insured by the Federal
Deposit Insurance Corporation ("FDIC"). Neither such party nor any Subsidiary
thereof holds any interest in a partnership or joint venture of any kind.

                   (c) Capitalization. (i) The authorized capital stock of
Star consists of (A) 400,000,000 shares of Star Common Stock, of which, as of
June 29, 1998, 95,778,921 shares were issued and outstanding and (B) 1,000,000
shares of preferred stock, no par value ("Star Preferred Stock"), issuable in
series, none of which, as of June 29, 1998, is issued or outstanding. Star has
designated (Y) 500,000 shares of Star Preferred Stock as "Series A Preferred
Stock" and has reserved such shares for issuance upon exercise of Preferred
Stock Purchase Rights under a Rights Agreement dated October 27, 1989 (the "Star
Rights Agreement"), between Star and Star Bank, N.A., as Rights Agent and (Z)
218,000 shares of Star Preferred Stock as "Series B Cumulative Preferred Stock."
Pursuant to the Star Rights Agreement, each certificate representing one share
of Star Common Stock also represents one Right (as defined in the Star Rights
Agreement). As of June 29, 1998 Star had options outstanding for 7,020,988
shares of Star Common Stock for issuance under various employee stock option and
incentive plans ("Star Stock Options"). From June 29, 1998 through the date of
this Agreement, no shares of Star Common Stock have been issued excluding not
more than 500 shares which may have been issued pursuant to stock-based,

Stock" and "Series D Preferred Stock" all of which have been redeemed. Pursuant
to the Firstar Rights Agreement, each certificate representing one share of
Firstar Common Stock also represents one-quarter Right (as defined in the
Firstar Rights Agreement). As of June 29, 1998 Firstar had options outstanding
for 6,037,093 shares of Firstar Common Stock for issuance under various employee
stock option and incentive plans ("Firstar Stock Options"). From June 29, 1998
through the date of this Agreement, no shares of Firstar Common Stock have been
issued excluding not more than 500 shares which may have been issued pursuant to
stock-based, director or employee benefit or incentive plans and programs.
Except as set forth above and except pursuant to the Firstar Rights Agreement,
there are no other Equity Securities of Firstar outstanding. All of the issued
and outstanding shares of Firstar Common Stock are validly issued, fully paid,
and nonassessable (subject to Section 180.0622(2)(b) of the WBCL), and have not
been issued in violation of any preemptive right of any stockholder of Firstar.

generally and the availability of equitable remedies). Firstar represents and

proceedings on the part of Foxtrot (DE) are necessary to approve this Agreement
and to consummate the transactions contemplated hereby.

                   (ii) Neither the execution, delivery and performance by
such party of this Agreement, nor the consummation by such party of the
transactions contemplated hereby, nor compliance by such party with any of the
provisions hereof, will (A) violate, conflict with or re-

                                      -12-

sult in a breach of any provisions of, or constitute a default (or an event
which, with notice or lapse of time or both, would constitute a default) or
result in the termination of, or accelerate the performance required by, or
result in a right of termination or acceleration of, or result in the creation

Subsidiary of such party under any of the terms, conditions or provisions of (I)
its articles or certificate of incorporation or bylaws or code of regulations,
or (II) any note, bond, mortgage, indenture, deed of trust, license, lease,

properties or assets of such party is a party or by which it may be bound, or to
which such party may be subject (assuming no default thereunder at the time of
the Merger), except (in the case of this clause (II)) for such violations,
conflicts, breaches or defaults which, either individually or in the aggregate,
will not have a Material Adverse Effect on such party or (B) subject to
compliance with the statutes and regulations referred to in paragraph (iii) of
this Section 4.3(d), to the best knowledge of such party, violate any judgment,

Regulatory Authority (as defined herein), no notice to, filing with, exemption
or review by, or authorization, consent or approval of, any public body or
authority is necessary in connection with the execution and delivery by such
party of this Agreement or the consummation by such party of the transactions
contemplated by this Agreement.

registration or statement or to pay such fees and assessments, either
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on such party. All such reports and statements filed
with any such Regulatory Authority are collectively referred to herein as the
"Star Reports" and the "Firstar Reports," as applicable. As of its respective
date, each of the Star Reports and the Firstar Reports, as applicable, of such
party complied in all material respects with all the rules and regulations
promulgated by the applicable Regulatory Authority and did not contain any
untrue statement of a material fact or omit to state a material fact required to

could result in the default under, the terms of any judgment, order, writ,
decree, permit, or license of any Regulatory Authority or court, whether
federal, state, municipal, or local and whether at law or in equity, except
where such default would not reasonably be expected to have a Material Adverse
Effect on such party. Neither such party nor any Subsidiary of such party is
subject to or reasonably likely to incur a liability as a result of its
ownership, operation, or use of any Property (as defined herein) of such party

Adverse Effect on such party.

connection with the Merger will comply as to form in all material respects with
the provisions of applicable law.

                   (j) Brokers and Finders. Except as set forth in the
engagement letter agreement between Firstar and Merrill Lynch, Pierce, Fenner &
Smith Incorporated, a true and complete copy of which has been provided to Star
prior to the date hereof, and the engagement letter 

                                      -15-
<PAGE>

agreement between Star and CS First Boston, a true and complete copy of which
has been provided to Firstar prior to the date hereof, neither such party nor
any of its Subsidiaries nor any of their respective officers, directors or
employees has employed any broker or finder or incurred any liability for any
financial advisory fees, brokerage fees, commissions or finder's fees, and no
broker or finder has acted directly or indirectly for such party or any of its
Subsidiaries in connection with this Agreement or the transactions contemplated
hereby.

                   (k) Litigation and Other Proceedings. (i) Neither such
party nor any of its Subsidiaries is a party to any, and there are no pending
or, to the knowledge of such party, threatened, legal, administrative, arbitral
or other proceedings, claims, actions or governmental or regulatory
investigations of any nature against such party or any of its Subsidiaries or
challenging the validity or propriety of the transactions contemplated by this
Agreement as to which, in any such case, there is a reasonable probability of an
adverse determination and which, if adversely determined either individually or
in the aggregate, would reasonably be expected to have a Material Adverse Effect
on such party.

                   (ii) There is no injunction, order, judgment, decree or
regulatory restriction (other than those that apply to similarly situated bank
holding companies or banks) imposed upon such party, any of its Subsidiaries or

Subsidiaries has paid, or set up adequate reserves on its respective Financial
Statements for the payment of, all taxes required to be paid in respect of the
periods covered by the Financial Statements and has paid or set up adequate
reserves on the most recent financial statements such party has filed under the
Exchange Act for the payment of all taxes anticipated to be payable in respect

for any tax, assessment or governmental charge have been proposed, asserted or
assessed in writing by any governmental or taxing authority against such party
or any Subsidiary of such party which have not been settled or would not be
covered by existing reserves. To the knowledge of such party, neither such party
nor any Subsidiary of such party is delinquent in the payment of any material
tax, assessment or governmental charge shown to be due on any Return (taking
into account extensions properly obtained), and no waiver of the time to assess
or collect any tax granted in writing by such party or any Subsidiary of such
party is pending. The federal and state income tax returns of such party and the
Subsidiaries of such party have been audited and finally settled by the IRS or

be deemed a "single employer" within the meaning of Section 4001 of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA").

                   (ii) Such party has made available to the other party

Material Adverse Effect (A) each of such party's Benefit Plans has been operated
and administered in all material respects in accordance with their terms and
with applicable laws, including, but not limited to, ERISA and the Code, (B)
each of such party's Benefit Plans intended to be "qualified" within the meaning
of Section 401(a) of the Code has received a favorable determination letter with
respect to such qualified status, or such Benefit Plans shall be submitted for
such determination in a timely fashion and there are no existing circumstances
or events that have occurred that could reasonably be expected to adversely
affect the qualified status of any such plan, (C) with respect to each Benefit
Plan of such party which is subject to Title IV of ERISA, the present value of
accrued benefits under such Plan, based upon the actuarial assumptions used for
funding purposes in the most recent actuarial report prepared by such Plan's
actuary with respect to such Plan, did not, as of its latest valuation date,
exceed the then current value of the assets of such Plan allocable to such
secured benefits, (D) no Benefit Plan of such party provides benefits,
including, without limitation, death or medical benefits (whether or not
insured), with respect to current or former employees or directors of such party
or its Subsidiaries beyond their retirement or other termination of service,

retirement benefits under any "employee pension plan" (as such term is defined
in Section 3(2) of ERISA), (3) deferred compensation benefits accrued as
liabilities on the books of such party or its Subsidiaries or (4) benefits the
full cost of which is borne by the current or former employee or director (or
his beneficiary), (E) no material liability under Title IV of ERISA has been
incurred by such party, its Subsidiaries or any ERISA Affiliate that has not
been satisfied in full, and no condition exists that could reasonably be
expected to present a material risk to such party, its Subsidiaries or any ERISA

business), (F) no Benefit Plan is a "multiemployer pension plan" (as such term
is defined in Section 3(37) of ERISA), (G) all contributions or other amounts
payable by such party or its Subsidiaries as of the Effective Time with respect

accrued in accordance with GAAP and Section 412 of the Code, (H) neither such
party nor its Subsidiaries has engaged in a transaction with respect to such
party's Benefit Plans in connection with which such party or its Subsidiaries
reasonably could be subject to either a material civil penalty accessed pursuant
to Section 409 or 502(i) of ERISA or a material tax imposed pursuant to Section
4975 or 4976 of the Code, and (I) to the best knowledge of such party, 

                                      -17-
<PAGE>

there are no pending, threatened or anticipated claims (other than routine
claims for benefits) by, on behalf of or against any of the Benefit Plans of
such party or any trusts related thereto.

                   (iv) Neither the execution and delivery of this Agreement
nor the consummation of the transactions contemplated hereby will (A) result in
any material payment (including, without limitation, severance, unemployment
compensation, "excess parachute payment" (within the meaning of Section 280G of
the Code), forgiveness of indebtedness or otherwise) becoming due to any
director or any employee of such party or any of its Subsidiaries under any
Benefit Plan of such party or otherwise, (B) materially increase any benefits
otherwise payable under any Benefit Plan of such party or (C) result in any
acceleration of the time of payment or vesting of any such benefits to any
material extent. Notwithstanding the foregoing, neither the execution of this
Agreement nor the consummation of the transactions contemplated hereby will
constitute or be deemed a "Change of Control" within the meaning of the Firstar
Supplemental Retirement Plan for Key Executives and the Firstar Corporation
Pension Plan.

                   (n) Accounting, Tax and Regulatory Matters. Neither such
party nor any Subsidiary of such party has taken or agreed to take any action or

the transactions contemplated hereby from qualifying as a "pooling of interests"
for accounting and financial reporting purposes or (iii) materially impede or

the Star Rights Agreement or the Firstar Rights Agreement, as applicable,
inapplicable to the Merger and the transactions contemplated by this Agreement

execution of this Agreement or the applicable stock option agreement or the
consummation of the transactions contemplated hereby or thereby) and (B) to
cause the Rights issued under the applicable Rights Agreement to expire

                   (s) Interest Rate Risk Management Instruments. Except as
would not reasonably be expected to have a Material Adverse Effect on such
party, all interest rate swaps, caps, floors and option agreements and other
interest rate risk management arrangements, whether entered into for the account
of such party or for the account of a customer of such party or one of its
Subsidiaries, were entered into in the ordinary course of business and, to such
party's knowledge, in accordance with prudent banking practice and applicable
rules, regulations and policies of any Regulatory Authority and with
counterparties believed to be financially responsible at the time and are legal,
valid and binding obligations of such party or one of its Subsidiaries
enforceable in accordance with their terms (except as may be limited by
bankruptcy, insolvency, moratorium, reorganization or similar laws affecting the
rights of creditors generally and the availability of equitable remedies), and
are in full force and effect. Except as would not reasonably be expected to have
a Material Adverse Effect on such party, such party and each of its Subsidiaries
have duly performed in all respects all of their obligations thereunder to the
extent that such obligations to perform have accrued; and, to such party's
knowledge, there are no breaches, violations or defaults or allegations or
assertions of such by any party thereunder.

                   (t) Insurance. Except as would not reasonably be expected to
have a Material Adverse Effect on such party, such party and its Subsidiaries
have in effect insurance coverage with reputable insurers which, in respect of
amounts, premiums, types and risks insured, constitutes reasonably adequate
coverage against all risks customarily insured against by bank holding companies
and their subsidiaries comparable in size and operations to such party and its
Subsidiaries.

                   (u) Agreements with Bank Regulators. Neither such party nor
any of its Subsidiaries is a party to any written agreement or memorandum of
understanding with, or a party to any commitment letter or similar undertaking
to, or is subject to any order or directive by, or is a recipient of any
extraordinary supervisory letter from, or has adopted any board resolutions at
the request of, any Regulatory Authority which restricts materially the conduct
of its business, or in any manner relates to its capital adequacy, its credit
policies or its management, nor has such party been advised by any Regulatory
Authority that is contemplating issuing or requesting (or is considering the
appropriateness of issuing or requesting) any such order, decree, agreement,
memorandum of understanding, extraordinary supervisory letter, commitment letter
or similar submission, or any such board resolutions.

                              ADDITIONAL AGREEMENTS

                   Section 6.1. Access and Information. Upon reasonable notice
and subject to applicable laws relating to the exchange of information, Star and
its Subsidiaries, on the one hand, and Firstar and its Subsidiaries, on the
other hand, shall each afford to each other, and to the other's accountants,
counsel and other representatives, access during normal business hours, during
the period prior to the Effective Time, to all their respective employees,
properties, books, contracts, commitments and records and, during such period,

                                      -23-
<PAGE>

promptly to the other (i) a copy of each report, schedule and other document
filed or received by it during such period pursuant to the requirements of
federal and state securities and banking laws (other than any such documents
which such party is not permitted to disclose under applicable laws) and
including, but not limited to, copies of internal quarterly reserve analyses,
credit quality assessments and credit information as set forth in Schedule 6.1
(ii) all other existing or regularly produced information concerning its
business, properties and personnel, in the case of (i) and (ii) as such other
party may reasonably request. Neither Star nor Firstar nor any of their
respective Subsidiaries shall be required to provide access to or to disclose
information where such access or disclosure would violate or prejudice the
rights of Star's or Firstar's, as the case may be, customers, jeopardize the
attorney-client privilege of the institution in possession or control of such
information or contravene any law, rule, regulation, order, judgment, decree,
fiduciary duty or binding agreement entered into prior to the date of this
Agreement. The parties hereto will make appropriate substitute disclosure
arrangements under circumstances in which the restrictions of the preceding
sentence apply.

                   Section 6.2. Registration Statement; Regulatory Matters. (a)
The parties shall prepare and file with the SEC as soon as is reasonably
practicable the Registration Statement (or the equivalent in the form of
preliminary proxy material) with respect to the shares of Foxtrot (DE) Common
Stock to be issued in the Reincorporation Merger and the Second Step Merger and
shall apply to the NYSE to list the shares of Foxtrot (DE) Common Stock to be
issued in connection with the transactions contemplated by this Agreement. The
parties shall prepare and file a notice with the Board as soon as reasonably
practicable. The parties shall use all reasonable efforts to cause the
Registration Statement to become effective. The parties shall also take any
action required to be taken under any applicable state blue sky or securities
laws in connection with the issuance of such shares, and Firstar and Star shall
furnish all information concerning their respective Subsidiaries and the
stockholders thereof as may reasonably be requested in connection with any such
action.

                   (b) The parties hereto shall cooperate with each other and
use their reasonable best efforts to promptly prepare and file all necessary
documentation, to effect all applications, notices, petitions and filings, to
obtain as promptly as practicable all permits, consents, approvals and
authorizations of all third parties and Regulatory Authorities which are
necessary or advisable to consummate the transactions contemplated by this
Agreement (including, without limitation, the Reincorporation Merger and the
Second Step Merger), and to comply with the terms and conditions of all such
permits, consents, approvals and authorizations of all such Regulatory
Authorities. Star and Firstar shall have the right to review in advance, and, to
the extent practicable, each will consult with the other on, in each case
subject to applicable laws relating to the exchange of information, all the
information relating to Star or Firstar, as the case may be, and any of their
respective Subsidiaries, which appear in any filing made with, or written
materials submitted to, any third party or any Regulatory Authority in
connection with the transactions contemplated by this Agreement. In exercising
the foregoing right, each of the parties hereto shall act reasonably and as
promptly as practicable. The parties hereto agree that they will consult with
each other with respect to the obtaining of all permits, consents, approvals and
authorizations of all third parties and Regulatory Authorities necessary or
advisable to consummate the 

                                      -24-
<PAGE>

transactions contemplated by this Agreement and each party will keep the other
apprised of the status of matters relating to the completion of the transactions
contemplated herein.

                   (c) Star and Firstar shall, upon request, furnish each
other with all information concerning themselves, their Subsidiaries, directors,
officers and stockholders and such other matters as may be reasonably necessary
or advisable in connection with the Proxy Statement, the Registration Statement
or any other statement, filing, notice or application made by or on behalf of
Star, Firstar or any of their respective Subsidiaries to any Regulatory
Authority in connection with the Reincorporation Merger and the Second Step
Merger and the other transactions contemplated by this Agreement.

                   (d) Star and Firstar shall promptly advise each other upon
receiving any communication from any Regulatory Authority whose consent or
approval is required for consummation of the transactions contemplated by this
Agreement which causes such party to believe that there is a reasonable
likelihood that any requisite approval of any Regulatory Authority will be
denied or materially delayed.

                   Section 6.3. Stockholder Approval. In accordance with
applicable law and stock exchange rules and its respective Articles of
Incorporation and By-Laws or Code of Regulations, each of the parties shall call
a meeting of their respective stockholders to be held as soon as practicable
after the Registration Statement is declared effective for the purpose of voting
upon the Reincorporation Merger and the Second Step Merger, as applicable, and
to take any other action for stockholders to authorize the transactions
contemplated by this Agreement (each, a "Meeting"). In connection therewith, the
parties shall prepare the Proxy Statement and, with the approval of each of Star
and Firstar, the Proxy Statement shall be filed with the SEC and mailed to the
respective stockholders of the parties. The parties' respective Boards of
Directors shall submit for approval of their respective stockholders the matters
to be voted upon in order to authorize the Merger. The respective Board of
Directors of the parties shall use their reasonable best efforts to obtain any
vote of their respective stockholders that is necessary for the approval and
adoption of this Agreement and consummation of the transactions contemplated
hereby.

                   Section 6.4. Current Information. During the period from the
date of this Agreement to the Effective Time, each party shall promptly furnish
the other with copies of all monthly and other interim financial statements as
the same become available and shall cause one or more of its designated
representatives to confer on a regular and frequent basis with representatives
of the other party. Each party shall promptly notify the other party of any
material change in its business or operations and of any governmental
complaints, investigations or hearings (or communications indicating that the
same may be contemplated), or the institution or, to its knowledge, the threat
of material litigation involving such party, and shall keep the other party
fully informed of such events.

                   Section 6.5. Agreements of Affiliates. (a) Not later than the
15th day prior to the mailing of the Proxy Statement, Firstar shall deliver to
Star and Star shall deliver to Firstar, a schedule of each person that, to the
best of its knowledge, is or is reasonably likely to be, as of the date of the
relevant Meeting, deemed to be an "affiliate" of it (each, an "Affiliate") as
that 

                                      -25-

term is used in SEC Accounting Series Releases 130 and 135 and Rule 145 under
the Securities Act.

                   (b) Firstar and Star shall each use its respective reasonable
best efforts to cause each person who may be deemed to be an Affiliate of
Firstar or Star, as the case may be, to execute and deliver to Firstar and Star
on or before the date of their respective Meetings an agreement to comply with
SEC Accounting Series Releases 130 and 135 and with Rule 145 under the
Securities Act. Such agreements shall be in the forms set forth in Exhibit E (in
the case of Firstar) and Exhibit F (in the case of Star).

                   (c) The Surviving Corporation shall use its reasonable best
efforts to publish as promptly as reasonably practical, but in no event later
than 45 days after the end of the first month after the Effective Time in which
there are at least 30 days of post-Merger combined operations (which month may
be the month in which the Effective Time occurs), combined sales and net income
figures as contemplated by and in accordance with the terms of SEC Accounting
Series Release No. 135.

                   Section 6.6. Expenses. Each party hereto shall bear its own
expenses incident to preparing, entering into and carrying out this Agreement
and to consummating the Merger provided that the expenses of Foxtrot (DE)
related to the preparation, filing and mailing of the Proxy Statement and the
Registration Statement shall be shared equally by the parties.

                   Section 6.7. Securities Act and Exchange Act Filings. (a) The
Surviving Corporation shall make all filings with the SEC that are described in
Section (c) of Rule 144 under the Securities Act for a period of two years
following the Effective Time.

                   (b) The parties shall cause Foxtrot (DE) to take all
corporate action necessary to reserve for issuance a sufficient number of shares
of Foxtrot (DE) Common Stock for delivery upon exercise of Star Stock Options
and Firstar Stock Options assumed by it in accordance with Sections 1.6 and 2.6.
As soon as practicable after the Effective Time, the parties shall cause Foxtrot
(DE) to file a registration statement on Form S-3 or Form S-8, as the case may
be (or any successor or other appropriate forms), or another appropriate form
with respect to the shares of Foxtrot (DE) Common Stock subject to such options
and to use its reasonable best efforts to maintain the effectiveness of such
registration statement or registration statements (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as such
options remain outstanding. With respect to those individuals who subsequent to
the Merger will be subject to the reporting requirements under Section 16(a) of
the Exchange Act, where applicable, the parties shall cause Foxtrot (DE) to
administer the Star Stock Plans and Firstar Stock Plans assumed pursuant to
Sections 1.6 and 2.6 in a manner that complies with Rule 16b-3 promulgated under
the Exchange Act to the extent such plans complied with such rule prior to the
Merger.

                   Section 6.8. Miscellaneous Agreements and Consents. (a)
Subject to the terms and conditions herein provided, each of the parties hereto
agrees to use its respective reasonable best efforts to take, or cause to be
taken, all action, and to do, or cause to be done, all things necessary, proper
or advisable under applicable laws and regulations to consummate and make
ef-

                                      -26-
<PAGE>

fective the transactions contemplated by this Agreement as expeditiously as
possible, including, without limitation, using its respective reasonable best
efforts to lift or rescind any injunction or restraining order or other order
adversely affecting the ability of the parties to consummate the transactions
contemplated hereby. Each party shall, and shall cause each of its respective
Subsidiaries to, use its reasonable best efforts to obtain consents of all third
parties necessary or, as agreed to by the parties, desirable for the
consummation of the transactions contemplated by this Agreement.

                   (b) The parties shall, prior to the Effective Time, (i)
consult and cooperate with each other regarding the implementation of those
policies and procedures to be established by Foxtrot (DE) for its operations,
including, without limitation, policies and procedures pertaining to the
accounting, asset/liability management, audit, credit, human resources, treasury
and legal functions, and (ii) shall make such modifications or changes to their
policies and practices, if any, and at such date prior to or as of the Effective
Time, as may be mutually agreed upon. Star and Firstar shall also consult with
respect to the character, amount and timing of restructuring charges to be taken
by each of them in connection with the transactions contemplated hereby and
shall take such charges in accordance with GAAP, as may be mutually agreed upon.
No party's representations, warranties and covenants contained in this Agreement
shall be determined to be untrue or breached in any respect for any purpose as a
consequence of any modifications or changes to such policies and practices which
may be undertaken on account of this Section 6.8(b).

                   Section 6.9. Employee Benefit Plans. (a) From and after the
Effective Time, unless otherwise mutually determined, the Firstar Benefit Plans
and Star Benefit Plans in effect as of the date of this Agreement shall remain
in effect with respect to employees of Firstar or Star (or their Subsidiaries),
respectively, covered by such Plans at the Effective Time until such time as the
Surviving Corporation shall, subject to applicable law, the terms of this
Agreement and the terms of such Plans, adopt new benefits with respect to
employees of the Surviving Corporation and its Subsidiaries (the "New Benefit
Plans"). Prior to the Closing Date, Firstar and Star shall cooperate in
reviewing, evaluating and analyzing the Star Benefit Plans and Firstar Benefit
Plans with a view towards developing appropriate New Benefit Plans for the
employees covered thereby subsequent to the consummation of the Merger. It is
the intention of Firstar and Star to develop New Benefit Plans, as soon as
reasonably practicable after the Effective Time, which, among other things, (i)
treat similarly situated employees on a substantially equivalent basis, taking
into account all relevant factors, including, without limitation, duties,
geographic location, tenure, qualifications and abilities, and (ii) do not
discriminate between employees of the Surviving Corporation who were covered by
Firstar Benefit Plans, on the one hand, and those covered by Star Benefit Plans,
on the other, at the Effective Time.

                   (b) The foregoing not withstanding, the Surviving
Corporation agrees to honor in accordance with their terms all benefits vested
as of the date hereof under the Star Benefit Plans or the Firstar Benefit Plans
or under other contracts, arrangements, commitments, or understandings described
in the Star Disclosure Schedule and the Firstar Disclosure Schedule.

                                      -27-
<PAGE>

                   (c) Nothing in this Section 6.9 shall be interpreted as
preventing the Surviving Corporation from amending, modifying or terminating any
Star Benefit Plans, Firstar Benefit Plans, or other contracts, arrangements,
commitments or understandings, in accordance with their terms and applicable
law.

                   Section 6.10. D&O Indemnification. (a) In the event of any
threatened or actual claim, action, suit, proceeding or investigation, whether
civil, criminal or administrative, including, without limitation, any such
claim, action, suit, proceeding or investigation in which any individual who is
now, or has been at any time prior to the date of this Agreement, or who becomes
prior to the Effective Time, a director or officer of Star, Firstar, Foxtrot
(DE) or any of their respective Subsidiaries, including any entity specified in
the Star Disclosure Schedule or the Firstar Disclosure Schedule (the
"Indemnified Parties"), is, or is threatened to be, made a party based in whole
or in part on, or arising in whole or in part out of, or pertaining to (i) the
fact that he is or was a director or officer of Star, Firstar, Foxtrot (DE) or
any of their respective Subsidiaries or any entity specified in the Star
Disclosure Schedule or the Firstar Disclosure Schedule or any of their
respective predecessors or (ii) this Agreement, the Option Agreements or any of
the transactions contemplated hereby or thereby, whether in any case asserted or
arising before or after the Effective Time, the parties hereto agree to
cooperate and use their best efforts to defend against and respond thereto. It
is understood and agreed that after the Effective Time, Foxtrot (DE) shall
indemnify and hold harmless, as and to the fullest extent permitted by law, each
such Indemnified Party against any losses, claims, damages, liabilities, costs,
expenses (including reasonable attorney's fees and expenses), judgments, fines
and amounts paid in settlement in connection with any such threatened or actual
claims, action, suit, proceeding or investigation, and in the event of any such
threatened or actual claim, action, suit, proceeding or investigation (whether
asserted or arising before or after the Effective Time); and Foxtrot (DE), after
consultation with an Indemnified Party, shall retain counsel and direct the
defense thereof, provided, however, that by virtue of the obligations herein set
forth, (A) Foxtrot (DE) shall not be liable to any Indemnified Party for any
legal expenses of other counsel or any other expenses incurred by any
Indemnified Party in connection with the defense thereof, except that if Foxtrot
(DE) fails or elects not to assume such defense or counsel for the Indemnified
Parties reasonably advises the Indemnified Parties that there are issues which
raise conflicts of interest between Foxtrot (DE) and the Indemnified Parties,
the Indemnified Parties may retain counsel reasonably satisfactory to them after
consultation with Foxtrot (DE), and Foxtrot (DE) shall pay the reasonable fees
and expenses of such counsel for the Indemnified Parties promptly as statements
therefor are received, (B) Foxtrot (DE) shall be obligated pursuant to this
paragraph to pay for only one firm of counsel (in addition to local counsel in
each applicable jurisdiction) for all Indemnified Parties, unless an Indemnified
Party shall have reasonably concluded, based on the advice of counsel and after
consultation with Foxtrot (DE), that in order to be adequately represented,
separate counsel is necessary for such Indemnified Party, in which case, Foxtrot
(DE) shall be obligated to pay for such separate counsel, (C) Foxtrot (DE) shall
not be liable for any settlement effected without its prior written consent
(which consent shall not be unreasonably withheld) and (D) Foxtrot (DE) shall
have no obligation hereunder to any Indemnified Party when and if a court of
competent jurisdiction shall ultimately determine, and such determination shall
have become final and nonappealable, that indemnification of such Indemnified
Party in the manner contemplated hereby is prohibited by applicable law. Foxtrot
(DE) shall, to the fullest extent permitted by law, advance 

                                      -28-

suit, proceeding, or investigation upon receipt of an undertaking to repay any
such advances of fees and expenses if such person is ultimately found not to be
entitled to indemnification therefor. Any Indemnified Party wishing to claim
Indemnification under this Section 6.10, upon learning of any such claim,
action, suit, proceeding or investigation, shall notify Foxtrot (DE) thereof,
provided that the failure to so notify shall not affect the obligations of
Foxtrot (DE) under this Section 6.10 except to the extent such failure to notify
materially prejudices Foxtrot (DE). Foxtrot (DE)'s obligations under this
Section 6.10 shall continue in full force and effect for a period of six years

Effective Time (or the period of the applicable statute of limitations, if
longer) by the directors' and officers' liability insurance policies maintained
by Star and Firstar, as applicable (provided that Foxtrot (DE) may substitute
therefor policies of at least the same coverage and amounts containing terms and
conditions which are not less advantageous than either of such policies) with
respect to acts or omissions occurring prior to the Effective Time which were
committed by such officers and directors in their capacity as such; provided,
however, that in no event shall Foxtrot (DE) be required to expend more than
200% of the current amount expended by Star and Firstar (the "Insurance Amount")
to maintain or procure insurance coverage pursuant hereto and provided further
that if Foxtrot (DE) is unable to maintain or obtain the insurance called for in
this Section 6.10(b), Foxtrot (DE) shall use its reasonable best efforts to
obtain as much comparable insurance as available for the Insurance Amount).

merger, or (ii) transfers or conveys all or substantially all of its properties
and assets to any person, then, and in each such case, to the extent necessary,
proper provision shall be made so that the successors and assigns of Foxtrot
(DE) assume the obligations set forth in this section.

for the benefit of, and shall be enforceable by, each Indemnified Party and his

financial reporting purposes (in the case of both clause (i) and clause (ii),
including, if necessary, to take reasonable steps to restructure the
transactions contemplated by this Agreement to so qualify and, in the case of
qualification as a "pooling of interests," including, if necessary, seeking any

regulations, and requirements of Regulatory Authorities, and provided further,
that neither Firstar nor Star shall be required to take any such action that, in
the opinion of its independent auditors, is not consistent with GAAP and
regulatory accounting principles if after consultation Firstar and Star agree,
Firstar and Star shall (i) establish and take such reserves and accruals at such
time as are agreed to conform Firstar's and Star's loan, accrual and reserve
policies to the other party's policies, and (ii) establish and take such
accruals, reserves and charges in order to implement such policies in respect of

Step Merger, as the case may be, the proper officers and directors of each party

existence under the name "Firstar Corporation" and to be governed by the laws of

the transactions contemplated by this Agreement. In the event of any such change
in structure appropriate adjustments shall be made to the terms of Exhibits C
and D to conform to the requirements of Wisconsin law.

                  THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
                   CERTAIN PROVISIONS CONTAINED HEREIN AND TO
                          RESALE RESTRICTIONS UNDER THE
                       SECURITIES ACT OF 1933, AS AMENDED


                  STOCK OPTION AGREEMENT, dated June 30, 1998, between Firstar
Corporation, a Wisconsin corporation ("Issuer"), and Star Banc Corporation, an
Ohio corporation ("Grantee").

                              W I T N E S S E T H:

                  WHEREAS, Grantee and Issuer have entered into an Agreement and
Plan of Reorganization of even date herewith (the "Merger Agreement"), which
agreement has been executed by the parties hereto immediately prior to this
Stock Option Agreement (the "Agreement"); and

                  WHEREAS, as a condition to Grantee's entering into the Merger
Agreement and in consideration therefor, Issuer has agreed to grant Grantee the
Option (as hereinafter defined);

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements set forth herein and in the Merger Agreement,
the parties hereto agree as follows:

                  1. (a) Issuer hereby grants to Grantee an unconditional,
irrevocable option (the "Option") to purchase, subject to the terms hereof, up
to 28,963,830 fully paid and non-assessable (subject to Section 180.0622(2)(b)
of the Wisconsin statutes) shares of Issuer's Common Stock, par value $1.25 per
share ("Common Stock"), at a price of $39.00 per share (the "Option Price");
provided, however, that in no event shall the number of shares of Common Stock
for which this Option is exercisable exceed 19.9% of the Issuer's issued and
outstanding shares of Common Stock without giving effect to any shares subject
to or issued pursuant to the Option. The number of shares of Common Stock that
may be received upon the exercise of the Option and the Option Price are subject
to adjustment as herein set forth.

                  (b) In the event that any additional shares of Common Stock
are either (i) issued or otherwise become outstanding after the date of this
Agreement (other than pursuant to this Agreement) or (ii) redeemed, repurchased,
retired or otherwise cease to be outstanding after the date of the Agreement,
the number of shares of Common Stock subject to the Option shall be increased or
decreased, as appropriate, so that, after such 


<PAGE>

issuance, such number equals 19.9% of the number of shares of Common Stock then
issued and outstanding without giving effect to any shares subject or issued
pursuant to the Option. Nothing contained in this Section 1(b) or elsewhere in
this Agreement shall be deemed to authorize Issuer or Grantee to breach any
provision of the Merger Agreement.

                  2. (a) The Holder (as hereinafter defined) may exercise the
Option, in whole or part, and from time to time, if, but only if, both an
Initial Triggering Event (as hereinafter defined) and a Subsequent Triggering
Event (as hereinafter defined) shall have occurred prior to the occurrence of an
Exercise Termination Event (as hereinafter defined), provided that the Holder
shall have sent the written notice of such exercise (as provided in subsection
(e) of this Section 2) within 90 days following such Subsequent Triggering
Event. Each of the following shall be an "Exercise Termination Event": (i) the
Effective Time (as defined in the Merger Agreement) of the Merger; (ii)
termination of the Merger Agreement in accordance with the provisions thereof if
such termination occurs prior to the occurrence of an Initial Triggering Event
except a termination by Grantee pursuant to Section 8.1(d) of the Merger
Agreement (unless the breach by Issuer giving rise to such right of termination
is non-volitional); or (iii) the passage of 12 months after termination of the
Merger Agreement if such termination follows the occurrence of an Initial
Triggering Event or is a termination by Grantee pursuant to Section 8.1(d)of the
Merger Agreement (unless the breach by Issuer giving rise to such right of
termination is non-volitional) (provided that if an Initial Triggering Event
continues or occurs beyond such termination and prior to the passage of such
12-month period, the Exercise Termination Event shall be 12 months from the
expiration of the Last Triggering Event but in no event more than 18 months
after such termination). The "Last Triggering Event" shall mean the last Initial
Triggering Event to expire. The term "Holder" shall mean the holder or holders
of the Option.

                  (b) The term "Initial Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                           (i) Issuer or any of its Significant Subsidiaries (as
         defined in Rule 1-02 of Regulation S-X promulgated by the Securities
         and Exchange Commission (the "SEC"))(each an "Issuer Subsidiary"),
         without having received Grantee's prior written consent, shall have
         entered into an agreement to engage in an Acquisition Transaction (as
         hereinafter defined) with any person (the term "person" for purposes of
         this Agreement having the meaning assigned thereto in 

                                      -2-
<PAGE>

         Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934,
         as amended (the "1934 Act"), and the rules and regulations thereunder)
         other than Grantee or any of its subsidiaries (each a "Grantee
         Subsidiary") or the Board of Directors of Issuer shall have
         recommended that the stockholders of Issuer approve or accept any
         Acquisition Transaction. For purposes of this Agreement, "Acquisition
         Transaction" shall mean (w) a merger or consolidation, or any similar
         transaction, involving Issuer or any Significant Subsidiary (as
         defined in Rule 1-02 of Regulation S-X promulgated by the Securities
         and Exchange Commission (the "SEC")) of Issuer, (x) a purchase, lease
         or other acquisition or assumption of 25% or more of the assets or
         deposits of Issuer and its Significant Subsidiaries taken as a whole,
         (y) a purchase or other acquisition (including by way of merger,
         consolidation, share exchange or otherwise) of securities representing
         10% or more of the voting power of Issuer, or (z) any substantially
         similar transaction; provided, however, that in no event shall any
         merger, consolidation, purchase or similar transaction (I) involving
         only the Issuer and one or more of its Subsidiaries, or involving only
         any two or more of such Subsidiaries, be deemed to be an Acquisition
         Transaction, provided that any such transaction is not entered into in
         violation of the terms of the Merger Agreement or (II) permitted by
         Article V or Article VI of the Merger Agreement be deemed to be an
         Acquisition Transaction;

                          (ii) Issuer or any Issuer Subsidiary, without having
         received Grantee's prior written consent, shall have authorized,
         recommended or proposed, or publicly announced its intention to
         authorize, recommend or propose, to engage in an Acquisition
         Transaction with any person other than Grantee or a Grantee Subsidiary,
         or the Board of Directors of Issuer shall have publicly withdrawn or
         modified, or publicly announced its intention to withdraw or modify, in
         any manner adverse to Grantee, its recommendation that the stockholders
         of Issuer approve the transactions contemplated by the Merger Agreement
         in anticipation of engaging in an Acquisition Transaction;

                         (iii) Any person other than Grantee, any Grantee
         Subsidiary or any Issuer Subsidiary where the Issuer subsidiary is
         acting in a fiduciary capacity in the ordinary course of its business
         shall have acquired beneficial ownership or the right to acquire
         beneficial ownership of 10% or more of the outstanding shares of Common
         Stock (the term "beneficial ownership" for purposes of this Agreement

                                      -3-
<PAGE>

         having the meaning assigned thereto in Section 13(d) of the 1934 Act,
         and the rules and regulations thereunder);

                          (iv) Any person other than Grantee or any Grantee
         Subsidiary shall have made a bona fide proposal to Issuer or its
         stockholders by public announcement or written communication that is or
         becomes the subject of public disclosure to engage in an Acquisition
         Transaction;

                           (v) After an overture is made by a third party to
         Issuer or its stockholders to engage in an Acquisition Transaction,
         Issuer shall have breached any covenant or obligation contained in the
         Merger Agreement and such breach (x) would entitle Grantee to terminate
         the Merger Agreement and (y) shall not have been cured prior to the
         Notice Date (as defined below); or

                          (vi) Any person other than Grantee or any Grantee
         Subsidiary, other than in connection with a transaction to which
         Grantee has given its prior written consent, shall have filed an
         application or notice with the Federal Reserve Board, or other federal
         or state bank regulatory authority, which application or notice has
         been accepted for processing, for approval to engage in an Acquisition
         Transaction.

                  (c) The term "Subsequent Triggering Event" shall mean either
of the following events or transactions occurring after the date hereof:

                           (i) The acquisition by any person (other than Grantee
         or any Grantee Subsidiary) of beneficial ownership of 20% or more of
         the then outstanding Common Stock; or

                          (ii) The occurrence of the Initial Triggering Event
         described in paragraph (i) of subsection (b) of this Section 2, except
         that the percentage referred to in clause (y) shall be 20%.

                  (d) Issuer shall notify Grantee promptly in writing of the
occurrence of any Initial Triggering Event or Subsequent Triggering Event of
which it has notice (together, a "Triggering Event"), it being understood that
the giving of such notice by Issuer shall not be a condition to the right of the
Holder to exercise the Option.

                  (e) In the event the Holder is entitled to and wishes to
exercise the Option, it shall send to Issuer a written notice (the date of which
being herein referred to as the "Notice Date") 

                                      -4-
<PAGE>

specifying (i) the total number of shares it will purchase pursuant to such
exercise and (ii) a place and date not earlier than three business days nor
later than 60 business days from the Notice Date for the closing of such
purchase (the "Closing Date"); provided that if prior notification to or
approval of the Federal Reserve Board or any other regulatory agency is required
in connection with such purchase, the Holder shall promptly file the required
notice or application for approval and shall expeditiously process the same and
the period of time that otherwise would run pursuant to this sentence shall run
instead from the date on which any required notification periods have expired or
been terminated or such approvals have been obtained and any requisite waiting
period or periods shall have passed. Any exercise of the Option shall be deemed
to occur on the Notice Date relating thereto.

                  (f) At the closing referred to in subsection (e) of this
Section 2, the Holder shall pay to Issuer the aggregate purchase price for the
shares of Common Stock purchased pursuant to the exercise of the Option in
immediately available funds by wire transfer to a bank account designated by
Issuer, provided that failure or refusal of Issuer to designate such a bank
account shall not preclude the Holder from exercising the Option.

                  (g) At such closing, simultaneously with the delivery of
immediately available funds as provided in subsection (f) of this Section 2,
Issuer shall deliver to the Holder a certificate or certificates representing
the number of shares of Common Stock purchased by the Holder and, if the Option
should be exercised in part only, a new Option evidencing the rights of the
Holder thereof to purchase the balance of the shares purchasable hereunder, and
the Holder shall deliver to Issuer a copy of this Agreement and a letter
agreeing that the Holder will not offer to sell or otherwise dispose of such
shares in violation of applicable law or the provisions of this Agreement.

                  (h) Certificates for Common Stock delivered at a closing
hereunder may be endorsed with a restrictive legend that shall read
substantially as follows:

                  "The transfer of the shares represented by this certificate is
                  subject to certain provisions of an agreement between the
                  registered holder hereof and Issuer and to resale restrictions
                  arising under the Securities Act of 1933, as amended. A copy
                  of such agreement is on file at the principal office of Issuer
                  and will be provided to the holder hereof without charge upon
                  receipt by Issuer of a written request therefor."

                                      -5-
<PAGE>

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Holder shall have delivered to Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions of this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall be removed
in its entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

                  (i) Upon the giving by the Holder to Issuer of written notice
of exercise of the Option provided for under subsection (e) of this Section 2
and the tender of the applicable purchase price in immediately available funds,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise, notwithstanding that the stock transfer books
of Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder. Issuer shall
pay all expenses, and any and all United States federal, state and local taxes
and other charges, that may be payable in connection with the preparation, issue
and delivery of stock certificates under this Section 2 in the name of the
Holder or its assignee, transferee or designee.

                  3. Issuer agrees: (i) that it will not, by charter amendment
or through reorganization, consolidation, merger, dissolution or sale of assets,
or by any other voluntary act, avoid or seek to avoid the observance or
performance of any of the covenants, stipulations or conditions to be observed
or performed hereunder by Issuer; (ii) promptly to take all action as may from
time to time be required (including (x) complying with all premerger
notification, reporting and waiting period requirements specified in 15 U.S.C.
ss. 18a and regulations promulgated thereunder and (y) in the event, under the
Bank Holding Company Act of 1956, as amended (the "BHCA"), or the Change in Bank
Control Act of 1978, as amended, or any state banking law, prior approval of or
notice to the Federal Reserve Board or to any state regulatory authority is
necessary before the Option may be exercised, cooperating fully with the Holder
in preparing such applications or notices and providing such 

                                      -6-
<PAGE>

information to the Federal Reserve Board or such state regulatory authority as
they may require) in order to permit the Holder to exercise the Option and
Issuer duly and effectively to issue shares of Common Stock pursuant hereto;
(iii) that if both an Initial Triggering Event and a Subsequent Triggering Event
shall have occurred prior to the occurrence of an Exercise Termination Event,
the Issuer shall use its reasonable best efforts to obtain additional authorized
but unissued shares which are free of preemptive rights so that the Option may
be exercised without additional authorization of Common Stock after giving
effect to all other options, warrants, convertible securities and other rights
to purchase Common Stock and (iv) promptly to take all actions to protect the
rights of the Holder (as set forth in Section 1(b)) against dilution.

                  4. This Agreement (and the Option granted hereby) are
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender of this Agreement at the principal office of Issuer, for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase, on the same terms and subject to the same conditions as are
set forth herein, in the aggregate the same number of shares of Common Stock
purchasable hereunder. The terms "Agreement" and "Option" as used herein include
any Stock Option Agreements and related Options for which this Agreement (and
the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

                  5. In addition to the adjustment in the number of shares of
Common Stock that are purchasable upon exercise of the Option pursuant to
Section 1 of this Agreement, the number of shares of Common Stock purchasable
upon the exercise of the Option and the Option Price shall be subject to
adjustment from time to time as provided in this Section 5. In the event of any
change in, or distributions in respect of, the Common Stock by reason of stock
dividends, splitups, mergers, recapitalizations, combinations, subdivisions,
conversions, exchanges of shares, distributions on or in respect of the Common
Stock that would be prohibited under the terms of the Merger Agreement, the type
and number of shares of Common Stock purchasable upon exercise hereof and the
Option Price shall be appropriately adjusted in such 

                                      -7-
<PAGE>

manner as shall fully preserve the economic benefits provided hereunder and
proper provision shall be made in any agreement governing any such transaction
to provide for such proper adjustment and the full satisfaction of the Issuer's
obligations hereunder.

                  6. Upon the occurrence of a Subsequent Triggering Event that
occurs prior to an Exercise Termination Event, Issuer shall, at the request of
Grantee delivered within 90 days of such Subsequent Triggering Event (whether on
its own behalf or on behalf of any subsequent holder of this Option (or part
thereof) or any of the shares of Common Stock issued pursuant hereto), promptly
prepare, file and keep current a shelf registration statement under the 1933 Act
covering this Option and any shares issued and issuable pursuant to this Option
and shall use its reasonable best efforts to cause such registration statement
to become effective and remain current in order to permit the sale or other
disposition of this Option and any shares of Common Stock issued upon total or
partial exercise of this Option ("Option Shares") in accordance with any plan of
disposition requested by Grantee. Issuer will use its reasonable best efforts to
cause such registration statement first to become effective and then to remain
effective for such period not in excess of 180 days from the day such
registration statement first becomes effective or such shorter time as may be
reasonably necessary to effect such sales or other dispositions. Grantee shall
have the right to demand two such registrations. The foregoing notwithstanding,
if, at the time of any request by Grantee for registration of the Option or
Option Shares as provided above, Issuer is in registration with respect to an
underwritten public offering of shares of Common Stock, and if in the good faith
judgment of the managing underwriter or managing underwriters, or, if none, the
sole underwriter or underwriters, of such offering the inclusion of the Holder's
Option or Option Shares would interfere with the successful marketing of the
shares of Common Stock offered by Issuer, the number of Option Shares otherwise
to be covered in the registration statement contemplated hereby may be reduced;
and provided, however, that after any such required reduction the number of
Option Shares to be included in such offering for the account of the Holder
shall constitute at least 25% of the total number of shares to be sold by the
Holder and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then the Issuer shall file a registration statement for the
balance as promptly as practical and no reduction shall thereafter occur. Each
such Holder shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder. If requested by
any such Holder in connection with such registration, Issuer shall become a
party to any 

                                      -8-
<PAGE>

underwriting agreement relating to the sale of such shares, but only to the
extent of obligating itself in respect of representations, warranties,
indemnities and other agreements customarily included in secondary offering
underwriting agreements for the Issuer. Upon receiving any request under this
Section 6 from any Holder, Issuer agrees to send a copy thereof to any other
person known to Issuer to be entitled to registration rights under this Section
6, in each case by promptly mailing the same, postage prepaid, to the address of
record of the persons entitled to receive such copies. Notwithstanding anything
to the contrary contained herein, in no event shall Issuer be obligated to
effect more than two registrations pursuant to this Section 6 by reason of the
fact that there shall be more than one Grantee as a result of any assignment or
division of this Agreement.

                  7. (a) From and after a Repurchase Event (as defined below),
(i) following a request of the Holder, delivered prior to an Exercise
Termination Event, Issuer (or any successor thereto) shall repurchase the Option
from the Holder at a price (the "Option Repurchase Price") equal to the amount
by which (A) the Market/Offer Price (as defined below) exceeds (B) the Option
Price, multiplied by the number of shares for which this Option may then be
exercised (provided that, notwithstanding anything to the contrary, if the
Issuer shall not have sufficient additional authorized but unissued shares or
treasury shares of Common Stock so that the Option may be exercised in full, the
Option Repurchase Price shall be calculated as if there were sufficient shares
which were authorized but unissued so that the Option could be exercised in
full) and (ii) at the request of the owner of Option Shares from time to time
(the "Owner"), delivered within 90 days of such occurrence (or such later period
as provided in Section 10), Issuer shall repurchase such number of the Option
Shares from the Owner as the Owner shall designate at a price (the "Option Share
Repurchase Price") equal to the Market/Offer Price multiplied by the number of
Option Shares so designated. The term "Market/Offer Price" shall mean the
highest of (i) the price per share of Common Stock at which a tender offer or
exchange offer therefor has been made, (ii) the price per share of Common Stock
to be paid by any third party pursuant to an agreement with Issuer, (iii) the
highest closing price for shares of Common Stock within the six-month period
immediately preceding the date the Holder gives notice of the required
repurchase of this Option or the Owner gives notice of the required repurchase
of Option Shares, as the case may be, or (iv) in the event of a sale of 25% or
more of the assets of the Issuer and its Significant Subsidiaries taken as a
whole, the sum of the price paid in such sale for such assets and the current
market value of the remaining assets of Issuer as determined by a 

                                      -9-
<PAGE>

nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to the Issuer, divided by
the number of shares of Common Stock of Issuer outstanding at the time of such
sale. In determining the Market/Offer Price, the value of consideration other
than cash shall be determined by a nationally recognized investment banking firm
selected by the Holder or Owner, as the case may be, and reasonably acceptable
to the Issuer.

                  (b) The Holder and the Owner, as the case may be, may exercise
its right to require Issuer to repurchase the Option and any Option Shares
pursuant to this Section 7 by surrendering for such purpose to Issuer, at its
principal office this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that the Holder
or the Owner, as the case may be, elects to require Issuer to repurchase this
Option and/or the Option Shares in accordance with the provisions of this
Section 7. Within the latter to occur of (x) five business days after the
surrender of the Option and/or certificates representing Option Shares and the
receipt of such notice or notices relating thereto and (y) the time that is
immediately prior to the occurrence of a Repurchase Event, Issuer shall deliver
or cause to be delivered to the Holder the Option Repurchase Price and/or to the
Owner the Option Share Repurchase Price therefor or the portion thereof, if any,
that Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that Issuer is prohibited under applicable
law or regulation from repurchasing the Option and/or the Option Shares in full,
Issuer shall immediately so notify the Holder and/or the Owner and thereafter
deliver or cause to be delivered, from time to time, to the Holder and/or the
Owner, as appropriate, the portion of the Option Repurchase Price and the Option
Share Repurchase Price, respectively, that it is no longer prohibited from
delivering, within five business days after the date on which Issuer is no
longer so prohibited; provided, however, that if Issuer at any time after
delivery of a notice of repurchase pursuant to paragraph (b) of this Section 7
is prohibited under applicable law or regulation from delivering to the Holder
and/or the Owner, as appropriate, the Option Repurchase Price and the Option
Share Repurchase Price, respectively, in full (and Issuer hereby undertakes to
use its reasonable best efforts to obtain all required regulatory and legal
approvals and to file any required notices, in each case as promptly as
practicable in order to accomplish such repurchase), the Holder or Owner may
revoke its notice of repurchase of the Option or the Option Shares either in
whole or to the extent of the prohibition, whereupon, in the latter case, Issuer
shall 

                                      -10-
<PAGE>

promptly (i) deliver to the Holder and/or the Owner, as appropriate, that
portion of the Option Repurchase Price or the Option Share Repurchase Price that
Issuer is not prohibited from delivering; and (ii) deliver, as appropriate,
either (A) to the Holder, a new Stock Option Agreement evidencing the right of
the Holder to purchase that number of shares of Common Stock obtained by
multiplying the number of shares of Common Stock for which the surrendered Stock
Option Agreement was exercisable at the time of delivery of the notice of
repurchase by a fraction, the numerator of which is the Option Repurchase Price
less the portion thereof theretofore delivered to the Holder and the denominator
of which is the Option Repurchase Price, or (B) to the Owner, a certificate for
the Option Shares it is then so prohibited from repurchasing.

                  (d) For purposes of this Section 7, a Repurchase Event shall
be deemed to have occurred (i) upon the consummation of any merger,
consolidation or similar transaction involving Issuer or any purchase, lease or
other acquisition of 25% or more of the assets of Issuer and its Significant
Subsidiaries taken as a whole, other than any such transaction which would not
constitute an Acquisition Transaction pursuant to the provisos to Section
2(b)(i) hereof or (ii) upon the acquisition by any person of beneficial
ownership of 50% or more of the then outstanding shares of Common Stock,
provided that no such event shall constitute a Repurchase Event unless a
Subsequent Triggering Event shall have occurred prior to an Exercise Termination
Event. The parties hereto agree that Issuer's obligations to repurchase the
Option or Option Shares under this Section 7 shall not terminate upon the
occurrence of an Exercise Termination Event unless no Subsequent Triggering
Event shall have occurred prior to the occurrence of an Exercise Termination
Event.

                  8. (a) In the event that prior to an Exercise Termination
Event, Issuer shall enter into an agreement other than the Merger Agreement (i)
to consolidate with or merge into any person, other than Grantee or one of its
Subsidiaries, and shall not be the continuing or surviving corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one of
its Subsidiaries, to merge into Issuer and Issuer shall be the continuing or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Common Stock shall be changed into or exchanged for stock or other
securities of any other person or cash or any other property or the then
outstanding shares of Common Stock shall after such merger represent less than
50% of the outstanding voting shares and voting share equivalents of the merged
company, or (iii) to sell or otherwise transfer all or substantially all of its
assets to any person, other than Grantee or one of its 

                                      -11-
<PAGE>

Subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provision so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option (the "Substitute
Option"), at the election of the Holder, of either (x) the Acquiring Corporation
(as hereinafter defined) or (y) any person that controls the Acquiring
Corporation.

                  (b) The following terms have the meanings indicated:

                           (1) "Acquiring Corporation" shall mean (i) the
         continuing or surviving corporation of a consolidation or merger with
         Issuer (if other than Issuer), (ii) Issuer in a merger in which Issuer
         is the continuing or surviving person, or (iii) the transferee of all
         or substantially all of Issuer's assets.

                           (2) "Substitute Common Stock" shall mean the common
         stock issued by the issuer of the Substitute Option upon exercise of
         the Substitute Option.

                           (3) "Assigned Value" shall mean the Market/Offer
         Price, as defined in Section 7.

                           (4) "Average Price" shall mean the average closing
         price of a share of the Substitute Common Stock for the one year
         immediately preceding the consolidation, merger or sale in question,
         but in no event higher than the closing price of the shares of
         Substitute Common Stock on the day preceding such consolidation, merger
         or sale; provided that if Issuer is the issuer of the Substitute
         Option, the Average Price shall be computed with respect to a share of
         common stock issued by the person merging into Issuer or by any company
         which controls or is controlled by such person, as the Holder may
         elect.

                  (c) The Substitute Option shall have the same terms as the
Option, provided, that if the terms of the Substitute Option cannot, for legal
reasons, be the same as the Option, such terms shall be as similar as possible
and in no event less advantageous to the Holder. The issuer of the Substitute
Option shall also enter into an agreement with the then Holder or Holders of the
Substitute Option in substantially the same form as this Agreement, which shall
be applicable to the Substitute Option, upon surrender of this Agreement.

                  (d) The Substitute Option shall be exercisable for such number
of shares of Substitute Common Stock as is equal to 

                                      -12-
<PAGE>

the Assigned Value multiplied by the number of shares of Common Stock for which
the Option is then exercisable, divided by the Average Price. The exercise price
of the Substitute Option per share of Substitute Common Stock shall then be
equal to the Option Price multiplied by a fraction, the numerator of which shall
be the number of shares of Common Stock for which the Option is then exercisable
and the denominator of which shall be the number of shares of Substitute Common
Stock for which the Substitute Option is exercisable.

                  (e) In no event, pursuant to any of the foregoing paragraphs,
shall the Substitute Option be exercisable for more than 19.9% of the shares of
Substitute Common Stock outstanding prior to exercise of the Substitute Option.
In the event that the Substitute Option would be exercisable for more than 19.9%
of the shares of Substitute Common Stock outstanding prior to exercise but for
this clause (e), the issuer of the Substitute Option (the "Substitute Option
Issuer") shall make a cash payment to Holder equal to the excess of (i) the
value of the Substitute Option without giving effect to the limitation in this
clause (e) over (ii) the value of the Substitute Option after giving effect to
the limitation in this clause (e). This difference in value shall be determined
by a nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to the Acquiring
Corporation.

                  (f) Issuer shall not enter into any transaction described in
subsection (a) of this Section 8 unless the Acquiring Corporation and any person
that controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder.

                  9. (a) At the request of the holder of the Substitute Option
(the "Substitute Option Holder"), the Substitute Option Issuer shall repurchase
the Substitute Option from the Substitute Option Holder at a price (the
"Substitute Option Repurchase Price") equal to (x) the amount by which (i) the
Highest Closing Price (as hereinafter defined) exceeds (ii) the exercise price
of the Substitute Option, multiplied by the number of shares of Substitute
Common Stock for which the Substitute Option may then be exercised plus (y)
Grantee's reasonable out-of-pocket expenses (to the extent not previously
reimbursed), and at the request of the owner (the "Substitute Share Owner") of
shares of Substitute Common Stock (the "Substitute Shares"), the Substitute
Option Issuer shall repurchase the Substitute Shares at a price (the "Substitute
Share Repurchase Price") equal to (x) the Highest Closing Price multiplied by
the number of Substitute Shares so designated plus (y) Grantee's reasonable
Out-of-Pocket Expenses (to the extent not previously reimbursed). The term
"Highest 

                                      -13-
<PAGE>

Closing Price" shall mean the highest closing price for shares of Substitute
Common Stock within the six-month period immediately preceding the date the
Substitute Option Holder gives notice of the required repurchase of the
Substitute Option or the Substitute Share Owner gives notice of the required
repurchase of the Substitute Shares, as applicable.

                  (b) The Substitute Option Holder and the Substitute Share
Owner, as the case may be, may exercise its respective right to require the
Substitute Option Issuer to repurchase the Substitute Option and the Substitute
Shares pursuant to this Section 9 by surrendering for such purpose to the
Substitute Option Issuer, at its principal office, the agreement for such
Substitute Option (or, in the absence of such an agreement, this Agreement) and
certificates for Substitute Shares accompanied by a written notice or notices
stating that the Substitute Option Holder or the Substitute Share Owner, as the
case may be, elects to require the Substitute Option Issuer to repurchase the
Substitute Option and/or the Substitute Shares in accordance with the provisions
of this Section 9. As promptly as practicable, and in any event within five
business days after the surrender of the Substitute Option and/or certificates
representing Substitute Shares and the receipt of such notice or notices
relating thereto, the Substitute Option Issuer shall deliver or cause to be
delivered to the Substitute Option Holder the Substitute Option Repurchase Price
and/or to the Substitute Share Owner the Substitute Share Repurchase Price
therefor or, in either case, the portion thereof which the Substitute Option
Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that the Substitute Option Issuer is
prohibited under applicable law or regulation from repurchasing the Substitute
Option and/or the Substitute Shares in part or in full, the Substitute Option
Issuer following a request for repurchase pursuant to this Section 9 shall
immediately so notify the Substitute Option Holder and/or the Substitute Share
Owner and thereafter deliver or cause to be delivered, from time to time, to the
Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the
portion of the Substitute Share Repurchase Price, respectively, which it is no
longer prohibited from delivering, within five business days after the date on
which the Substitute Option Issuer is no longer so prohibited; provided,
however, that if the Substitute Option Issuer is at any time after delivery of a
notice of repurchase pursuant to subsection (b) of this Section 9 prohibited
under applicable law or regulation from delivering to the Substitute Option
Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option
Repurchase Price and the Substitute Share Repurchase 

                                      -14-
<PAGE>

Price, respectively, in full (and the Substitute Option Issuer shall use its
best efforts to obtain all required regulatory and legal approvals, in each case
as promptly as practicable in order to accomplish such repurchase), the
Substitute Option Holder or Substitute Share Owner may revoke its notice of
repurchase of the Substitute Option or the Substitute Shares either in whole or
to the extent of the prohibition, whereupon, in the latter case, the Substitute
Option Issuer shall promptly (i) deliver to the Substitute Option Holder or
Substitute Share Owner, as appropriate, that portion of the Substitute Option
Repurchase Price or the Substitute Share Repurchase Price that the Substitute
Option Issuer is not prohibited from delivering; and (ii) deliver, as
appropriate, either (A) to the Substitute Option Holder, a new Substitute Option
evidencing the right of the Substitute Option Holder to purchase that number of
shares of the Substitute Common Stock obtained by multiplying the number of
shares of the Substitute Common Stock for which the surrendered Substitute
Option was exercisable at the time of delivery of the notice of repurchase by a
fraction, the numerator of which is the Substitute Option Repurchase Price less
the portion thereof theretofore delivered to the Substitute Option Holder and
the denominator of which is the Substitute Option Repurchase Price, or (B) to
the Substitute Share Owner, a certificate for the Substitute Common Shares it is
then so prohibited from repurchasing.

                  10. The 90-day period for exercise of certain rights under
Sections 2, 6, 7 and 13 shall be extended: (i) to the extent necessary to obtain
all regulatory approvals for the exercise of such rights, and for the expiration
of all statutory waiting periods; (ii) to the extent necessary to avoid
liability under Section 16(b) of the 1934 Act by reason of such exercise and
(iii) during any period in which Grantee is precluded from exercising such
rights due to an injunction or other legal restriction, plus in each case such
additional period as is reasonably necessary for the exercise of such rights
promptly following the obtaining of such approvals or the expiration of such
periods.

                  11. Issuer hereby represents and warrants to Grantee as
follows:

                  (a) Issuer has full corporate power and authority to execute
and deliver this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board of Directors of Issuer and no other corporate proceedings on the part of
Issuer are necessary to authorize this Agreement 

                                      -15-
<PAGE>

or to consummate the transactions so contemplated. This Agreement has been duly
and validly executed and delivered by Issuer.

                  (b) Subject to Section 3, Issuer has taken all necessary
corporate action to authorize and reserve and to permit it to issue, and at all
times from the date hereof through the termination of this Agreement in
accordance with its terms will have reserved for issuance upon the exercise of
the Option, that number of shares of Common Stock equal to the maximum number of
shares of Common Stock at any time and from time to time issuable hereunder, and
all such shares, upon issuance pursuant hereto, will be duly authorized, validly
issued, fully paid, nonassessable (subject to Section 180.0622(2)(b) of the
WGBL), and will be delivered free and clear of all claims, liens, encumbrance
and security interests and not subject to any preemptive rights.

                  (c) Issuer has taken all action (including amending the Rights
Agreement) so that the entering into of this Option Agreement, the acquisition
of shares of Common Stock hereunder and the other transactions contemplated
hereby do not and will not result in the grant of any rights to any person under
the Rights Agreement or enable or require the Rights to be exercised,
distributed or triggered.

                  12. Grantee hereby represents and warrants to Issuer that:

                  (a) Grantee has all requisite corporate power and authority to
enter into this Agreement and, subject to any approvals or consents referred to
herein, to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by all necessary corporate action on the part
of Grantee. This Agreement has been duly executed and delivered by Grantee.

                  (b) The Option is not being, and any shares of Common Stock or
other securities acquired by Grantee upon exercise of the Option will not be,
acquired with a view to the public distribution thereof and will not be
transferred or otherwise disposed of except in a transaction registered or
exempt from registration under the Securities Act.

                  13. Neither of the parties hereto may assign any of its rights
or obligations under this Option Agreement or the Option created hereunder to
any other person, without the express written consent of the other party, except
that in the event a 

                                      -16-
<PAGE>

Subsequent Triggering Event shall have occurred prior to an Exercise Termination
Event, Grantee, subject to the express provisions hereof, may assign in whole or
in part its rights and obligations hereunder within 90 days following such
Subsequent Triggering Event (or such later period as provided in Section 10);
provided, however, that until the date 15 days following the date on which the
Federal Reserve Board approves an application by Grantee under the BHCA to
acquire the shares of Common Stock subject to the Option, Grantee may not assign
its rights under the Option except in (i) a widely dispersed public
distribution, (ii) a private placement in which no one party acquires the right
to purchase in excess of 2% of the voting shares of Issuer, (iii) an assignment
to a single party (e.g., a broker or investment banker) for the purpose of
conducting a widely dispersed public distribution on Grantee's behalf, or (iv)
any other manner approved by the Federal Reserve Board.

                  14. Each of Grantee and Issuer will use its reasonable best
efforts to make all filings with, and to obtain consents of, all third parties
and governmental authorities necessary to the consummation of the transactions
contemplated by this Agreement, including without limitation making application
to list the shares of Common Stock issuable hereunder on the New York Stock
Exchange upon official notice of issuance and applying to the Federal Reserve
Board under the BHCA for approval to acquire the shares issuable hereunder, but
Grantee shall not be obligated to apply to state banking authorities for
approval to acquire the shares of Common Stock issuable hereunder until such
time, if ever, as it deems appropriate to do so.

                  15. Grantee in its sole discretion may, at any time during
which Issuer would be required to repurchase the Option or any Option Shares
pursuant to Section 7, surrender the Option (together with any Option Shares
issued to and then owned by the Holder) to Issuer in exchange for a cash payment
equal to the Surrender Price (as defined herein); provided, however, that
Grantee may not exercise its rights pursuant to this Section 15 if Issuer has
previously repurchased the Option (or any portion thereof) or any Option Shares
pursuant to Section 7. The "Surrender Price" shall be equal to (i) $300 million,
plus (ii) if applicable, the aggregate purchase price previously paid pursuant
hereto by Grantee with respect to any Option Shares, minus (iii) if applicable,
the excess of (A) the net cash, if any, received by Grantee pursuant to the
arm's-length sale of Option Shares (or any other securities into which such
Option Shares were converted or exchanged) to any party not affiliated with
Grantee, over (B) the purchase price paid by Grantee with respect to such Option
Shares.

                                      -17-
<PAGE>

                  (b) Grantee may exercise its right to surrender the Option and
any Option Shares pursuant to this Section 15 by surrendering for such purchase
to Issuer, at its principal office, this Agreement, together with certificates
for Option Shares, if any, accompanied by a written notice stating (i) that
Grantee elects to surrender the Option and Option Shares, if any, in accordance
with the provisions of this Section 15 and (ii) the Surrender Price. Within two
business days after the surrender of the Option and the Option Shares, if
applicable, Issuer shall deliver or cause to be delivered to Grantee the
Surrender Price.

                  (c) To the extent that the Issuer is prohibited under
applicable law or regulation from paying the Surrender Price to Grantee in full,
Issuer shall immediately so notify Grantee and thereafter deliver, or cause to
be delivered, from time to time, to Grantee, that portion of the Surrender Price
that Issuer is not or no longer prohibited from paying, within two business days
after the date on which Issuer is no longer so prohibited; provided, however,
that if Issuer at any time after delivery of a notice of Surrender pursuant to
Section 15(b) is prohibited under applicable law or regulation from paying to
Grantee the Surrender Price in full, (i) Issuer shall (A) use its reasonable
best efforts to obtain all required regulatory and legal approvals and to file
any required notices as promptly as practicable in order to make such payments,
(B) within two business days of the submission or receipt of any documents
relating to any such regulatory and legal approvals, provide Grantee with copies
of the same, and (C) keep Grantee advised of both the status of any such request
for regulatory and legal approvals and any discussions with any relevant
regulatory or other third party reasonably related to the same, and (ii) Grantee
may revoke such notice of surrender by delivery of a notice of revocation, the
Exercise Termination Event shall be extended to a date six months from the date
on which the Exercise Termination Event would have occurred if not for the
provisions of this Section 15(c) (during which period Grantee may exercise any
of its rights hereunder, including any and all rights pursuant to this Section
15).

                  (d) Grantee shall have rights substantially identical to those
set forth in paragraphs (a), (b) and (c) of this Section 15 with respect to the
Substitute Option and the Substitute Option Issuer during any period in which
the Substitute Option Issuer would be required to repurchase the Substitute
Option pursuant to Section 9.

                  16. The parties hereto acknowledge that damages would be an
inadequate remedy for a breach of this Agreement by either party hereto and that
the obligations of the parties hereto shall 

                                      -18-
<PAGE>

be enforceable by either party hereto through injunctive or other equitable
relief.

                  17. If any term, provision, covenant or restriction contained
in this Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or invalidated. If for any reason such court or regulatory agency determines
that the Holder is not permitted to acquire, or Issuer is not permitted to
repurchase pursuant to Section 7, the full number of shares of Common Stock
provided in Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5
hereof), it is the express intention of Issuer (which shall be binding on the
Substitute Option Issuer) to allow the Holder to acquire or to require Issuer or
Substitute Option Issuer to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof.

                  18. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered
in person, by telecopy or by registered or certified mail (postage prepaid,
return receipt requested) at the respective addresses of the parties set forth
in the Merger Agreement.

                  19. This Agreement shall be governed by and construed in
accordance with the laws of the State of Wisconsin, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof
(except to the extent that mandatory provisions of federal law apply).

                  20. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of which
shall constitute one and the same agreement.

                  21. Except as otherwise expressly provided herein, each of the
parties hereto shall bear and pay all costs and expenses incurred by it or on
its behalf in connection with the transactions contemplated hereunder, including
fees and expenses of its own financial consultants, investment bankers,
accountants and counsel.

                  22. Except as otherwise expressly provided herein or in the
Merger Agreement, this Agreement contains the entire agreement between the
parties with respect to the transactions contemplated hereunder and supersedes
all prior arrangements or understandings with respect thereof, written or oral.
The terms 

                                      -19-
<PAGE>

and conditions of this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assigns.
Nothing in this Agreement, expressed or implied, is intended to confer upon any
party, other than the parties hereto, and their respective successors except as
assigns, any rights, remedies, obligations or liabilities under or by reason of
this Agreement, except as expressly provided herein.

                  23. Capitalized terms used in this Agreement and not defined
herein shall have the meanings assigned thereto in the Merger Agreement.

Agreement to be executed on its behalf by its officers thereunto duly

                  THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
                   CERTAIN PROVISIONS CONTAINED HEREIN AND TO
                          RESALE RESTRICTIONS UNDER THE
                       SECURITIES ACT OF 1933, AS AMENDED


                  STOCK OPTION AGREEMENT, dated June 30, 1998, between Firstar
Corporation, a Wisconsin corporation ("Issuer"), and Star Banc Corporation, an
Ohio corporation ("Grantee").

                              W I T N E S S E T H:

                  WHEREAS, Grantee and Issuer have entered into an Agreement and
Plan of Reorganization of even date herewith (the "Merger Agreement"), which
agreement has been executed by the parties hereto immediately prior to this
Stock Option Agreement (the "Agreement"); and

                  WHEREAS, as a condition to Grantee's entering into the Merger
Agreement and in consideration therefor, Issuer has agreed to grant Grantee the
Option (as hereinafter defined);

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements set forth herein and in the Merger Agreement,
the parties hereto agree as follows:

                  1. (a) Issuer hereby grants to Grantee an unconditional,
irrevocable option (the "Option") to purchase, subject to the terms hereof, up
to 28,963,830 fully paid and non-assessable (subject to Section 180.0622(2)(b)
of the Wisconsin statutes) shares of Issuer's Common Stock, par value $1.25 per
share ("Common Stock"), at a price of $39.00 per share (the "Option Price");
provided, however, that in no event shall the number of shares of Common Stock
for which this Option is exercisable exceed 19.9% of the Issuer's issued and
outstanding shares of Common Stock without giving effect to any shares subject
to or issued pursuant to the Option. The number of shares of Common Stock that
may be received upon the exercise of the Option and the Option Price are subject
to adjustment as herein set forth.

                  (b) In the event that any additional shares of Common Stock
are either (i) issued or otherwise become outstanding after the date of this
Agreement (other than pursuant to this Agreement) or (ii) redeemed, repurchased,
retired or otherwise cease to be outstanding after the date of the Agreement,
the number of shares of Common Stock subject to the Option shall be increased or
decreased, as appropriate, so that, after such 


<PAGE>

issuance, such number equals 19.9% of the number of shares of Common Stock then
issued and outstanding without giving effect to any shares subject or issued
pursuant to the Option. Nothing contained in this Section 1(b) or elsewhere in
this Agreement shall be deemed to authorize Issuer or Grantee to breach any
provision of the Merger Agreement.

                  2. (a) The Holder (as hereinafter defined) may exercise the
Option, in whole or part, and from time to time, if, but only if, both an
Initial Triggering Event (as hereinafter defined) and a Subsequent Triggering
Event (as hereinafter defined) shall have occurred prior to the occurrence of an
Exercise Termination Event (as hereinafter defined), provided that the Holder
shall have sent the written notice of such exercise (as provided in subsection
(e) of this Section 2) within 90 days following such Subsequent Triggering
Event. Each of the following shall be an "Exercise Termination Event": (i) the
Effective Time (as defined in the Merger Agreement) of the Merger; (ii)
termination of the Merger Agreement in accordance with the provisions thereof if
such termination occurs prior to the occurrence of an Initial Triggering Event
except a termination by Grantee pursuant to Section 8.1(d) of the Merger
Agreement (unless the breach by Issuer giving rise to such right of termination
is non-volitional); or (iii) the passage of 12 months after termination of the
Merger Agreement if such termination follows the occurrence of an Initial
Triggering Event or is a termination by Grantee pursuant to Section 8.1(d)of the
Merger Agreement (unless the breach by Issuer giving rise to such right of
termination is non-volitional) (provided that if an Initial Triggering Event
continues or occurs beyond such termination and prior to the passage of such
12-month period, the Exercise Termination Event shall be 12 months from the
expiration of the Last Triggering Event but in no event more than 18 months
after such termination). The "Last Triggering Event" shall mean the last Initial
Triggering Event to expire. The term "Holder" shall mean the holder or holders
of the Option.

                  (b) The term "Initial Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                           (i) Issuer or any of its Significant Subsidiaries (as
         defined in Rule 1-02 of Regulation S-X promulgated by the Securities
         and Exchange Commission (the "SEC"))(each an "Issuer Subsidiary"),
         without having received Grantee's prior written consent, shall have
         entered into an agreement to engage in an Acquisition Transaction (as
         hereinafter defined) with any person (the term "person" for purposes of
         this Agreement having the meaning assigned thereto in 

                                      -2-
<PAGE>

         Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934,
         as amended (the "1934 Act"), and the rules and regulations thereunder)
         other than Grantee or any of its subsidiaries (each a "Grantee
         Subsidiary") or the Board of Directors of Issuer shall have
         recommended that the stockholders of Issuer approve or accept any
         Acquisition Transaction. For purposes of this Agreement, "Acquisition
         Transaction" shall mean (w) a merger or consolidation, or any similar
         transaction, involving Issuer or any Significant Subsidiary (as
         defined in Rule 1-02 of Regulation S-X promulgated by the Securities
         and Exchange Commission (the "SEC")) of Issuer, (x) a purchase, lease
         or other acquisition or assumption of 25% or more of the assets or
         deposits of Issuer and its Significant Subsidiaries taken as a whole,
         (y) a purchase or other acquisition (including by way of merger,
         consolidation, share exchange or otherwise) of securities representing
         10% or more of the voting power of Issuer, or (z) any substantially
         similar transaction; provided, however, that in no event shall any
         merger, consolidation, purchase or similar transaction (I) involving
         only the Issuer and one or more of its Subsidiaries, or involving only
         any two or more of such Subsidiaries, be deemed to be an Acquisition
         Transaction, provided that any such transaction is not entered into in
         violation of the terms of the Merger Agreement or (II) permitted by
         Article V or Article VI of the Merger Agreement be deemed to be an
         Acquisition Transaction;

                          (ii) Issuer or any Issuer Subsidiary, without having
         received Grantee's prior written consent, shall have authorized,
         recommended or proposed, or publicly announced its intention to
         authorize, recommend or propose, to engage in an Acquisition
         Transaction with any person other than Grantee or a Grantee Subsidiary,
         or the Board of Directors of Issuer shall have publicly withdrawn or
         modified, or publicly announced its intention to withdraw or modify, in
         any manner adverse to Grantee, its recommendation that the stockholders
         of Issuer approve the transactions contemplated by the Merger Agreement
         in anticipation of engaging in an Acquisition Transaction;

                         (iii) Any person other than Grantee, any Grantee
         Subsidiary or any Issuer Subsidiary where the Issuer subsidiary is
         acting in a fiduciary capacity in the ordinary course of its business
         shall have acquired beneficial ownership or the right to acquire
         beneficial ownership of 10% or more of the outstanding shares of Common
         Stock (the term "beneficial ownership" for purposes of this Agreement

                                      -3-
<PAGE>

         having the meaning assigned thereto in Section 13(d) of the 1934 Act,
         and the rules and regulations thereunder);

                          (iv) Any person other than Grantee or any Grantee
         Subsidiary shall have made a bona fide proposal to Issuer or its
         stockholders by public announcement or written communication that is or
         becomes the subject of public disclosure to engage in an Acquisition
         Transaction;

                           (v) After an overture is made by a third party to
         Issuer or its stockholders to engage in an Acquisition Transaction,
         Issuer shall have breached any covenant or obligation contained in the
         Merger Agreement and such breach (x) would entitle Grantee to terminate
         the Merger Agreement and (y) shall not have been cured prior to the
         Notice Date (as defined below); or

                          (vi) Any person other than Grantee or any Grantee
         Subsidiary, other than in connection with a transaction to which
         Grantee has given its prior written consent, shall have filed an
         application or notice with the Federal Reserve Board, or other federal
         or state bank regulatory authority, which application or notice has
         been accepted for processing, for approval to engage in an Acquisition
         Transaction.

                  (c) The term "Subsequent Triggering Event" shall mean either
of the following events or transactions occurring after the date hereof:

                           (i) The acquisition by any person (other than Grantee
         or any Grantee Subsidiary) of beneficial ownership of 20% or more of
         the then outstanding Common Stock; or

                          (ii) The occurrence of the Initial Triggering Event
         described in paragraph (i) of subsection (b) of this Section 2, except
         that the percentage referred to in clause (y) shall be 20%.

                  (d) Issuer shall notify Grantee promptly in writing of the
occurrence of any Initial Triggering Event or Subsequent Triggering Event of
which it has notice (together, a "Triggering Event"), it being understood that
the giving of such notice by Issuer shall not be a condition to the right of the
Holder to exercise the Option.

                  (e) In the event the Holder is entitled to and wishes to
exercise the Option, it shall send to Issuer a written notice (the date of which
being herein referred to as the "Notice Date") 

                                      -4-
<PAGE>

specifying (i) the total number of shares it will purchase pursuant to such
exercise and (ii) a place and date not earlier than three business days nor
later than 60 business days from the Notice Date for the closing of such
purchase (the "Closing Date"); provided that if prior notification to or
approval of the Federal Reserve Board or any other regulatory agency is required
in connection with such purchase, the Holder shall promptly file the required
notice or application for approval and shall expeditiously process the same and
the period of time that otherwise would run pursuant to this sentence shall run
instead from the date on which any required notification periods have expired or
been terminated or such approvals have been obtained and any requisite waiting
period or periods shall have passed. Any exercise of the Option shall be deemed
to occur on the Notice Date relating thereto.

                  (f) At the closing referred to in subsection (e) of this
Section 2, the Holder shall pay to Issuer the aggregate purchase price for the
shares of Common Stock purchased pursuant to the exercise of the Option in
immediately available funds by wire transfer to a bank account designated by
Issuer, provided that failure or refusal of Issuer to designate such a bank
account shall not preclude the Holder from exercising the Option.

                  (g) At such closing, simultaneously with the delivery of
immediately available funds as provided in subsection (f) of this Section 2,
Issuer shall deliver to the Holder a certificate or certificates representing
the number of shares of Common Stock purchased by the Holder and, if the Option
should be exercised in part only, a new Option evidencing the rights of the
Holder thereof to purchase the balance of the shares purchasable hereunder, and
the Holder shall deliver to Issuer a copy of this Agreement and a letter
agreeing that the Holder will not offer to sell or otherwise dispose of such
shares in violation of applicable law or the provisions of this Agreement.

                  (h) Certificates for Common Stock delivered at a closing
hereunder may be endorsed with a restrictive legend that shall read
substantially as follows:

                  "The transfer of the shares represented by this certificate is
                  subject to certain provisions of an agreement between the
                  registered holder hereof and Issuer and to resale restrictions
                  arising under the Securities Act of 1933, as amended. A copy
                  of such agreement is on file at the principal office of Issuer
                  and will be provided to the holder hereof without charge upon
                  receipt by Issuer of a written request therefor."

                                      -5-
<PAGE>

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Holder shall have delivered to Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions of this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall be removed
in its entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

                  (i) Upon the giving by the Holder to Issuer of written notice
of exercise of the Option provided for under subsection (e) of this Section 2
and the tender of the applicable purchase price in immediately available funds,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise, notwithstanding that the stock transfer books
of Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder. Issuer shall
pay all expenses, and any and all United States federal, state and local taxes
and other charges, that may be payable in connection with the preparation, issue
and delivery of stock certificates under this Section 2 in the name of the
Holder or its assignee, transferee or designee.

                  3. Issuer agrees: (i) that it will not, by charter amendment
or through reorganization, consolidation, merger, dissolution or sale of assets,
or by any other voluntary act, avoid or seek to avoid the observance or
performance of any of the covenants, stipulations or conditions to be observed
or performed hereunder by Issuer; (ii) promptly to take all action as may from
time to time be required (including (x) complying with all premerger
notification, reporting and waiting period requirements specified in 15 U.S.C.
ss. 18a and regulations promulgated thereunder and (y) in the event, under the
Bank Holding Company Act of 1956, as amended (the "BHCA"), or the Change in Bank
Control Act of 1978, as amended, or any state banking law, prior approval of or
notice to the Federal Reserve Board or to any state regulatory authority is
necessary before the Option may be exercised, cooperating fully with the Holder
in preparing such applications or notices and providing such 

                                      -6-
<PAGE>

information to the Federal Reserve Board or such state regulatory authority as
they may require) in order to permit the Holder to exercise the Option and
Issuer duly and effectively to issue shares of Common Stock pursuant hereto;
(iii) that if both an Initial Triggering Event and a Subsequent Triggering Event
shall have occurred prior to the occurrence of an Exercise Termination Event,
the Issuer shall use its reasonable best efforts to obtain additional authorized
but unissued shares which are free of preemptive rights so that the Option may
be exercised without additional authorization of Common Stock after giving
effect to all other options, warrants, convertible securities and other rights
to purchase Common Stock and (iv) promptly to take all actions to protect the
rights of the Holder (as set forth in Section 1(b)) against dilution.

                  4. This Agreement (and the Option granted hereby) are
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender of this Agreement at the principal office of Issuer, for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase, on the same terms and subject to the same conditions as are
set forth herein, in the aggregate the same number of shares of Common Stock
purchasable hereunder. The terms "Agreement" and "Option" as used herein include
any Stock Option Agreements and related Options for which this Agreement (and
the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

                  5. In addition to the adjustment in the number of shares of
Common Stock that are purchasable upon exercise of the Option pursuant to
Section 1 of this Agreement, the number of shares of Common Stock purchasable
upon the exercise of the Option and the Option Price shall be subject to
adjustment from time to time as provided in this Section 5. In the event of any
change in, or distributions in respect of, the Common Stock by reason of stock
dividends, splitups, mergers, recapitalizations, combinations, subdivisions,
conversions, exchanges of shares, distributions on or in respect of the Common
Stock that would be prohibited under the terms of the Merger Agreement, the type
and number of shares of Common Stock purchasable upon exercise hereof and the
Option Price shall be appropriately adjusted in such 

                                      -7-
<PAGE>

manner as shall fully preserve the economic benefits provided hereunder and
proper provision shall be made in any agreement governing any such transaction
to provide for such proper adjustment and the full satisfaction of the Issuer's
obligations hereunder.

                  6. Upon the occurrence of a Subsequent Triggering Event that
occurs prior to an Exercise Termination Event, Issuer shall, at the request of
Grantee delivered within 90 days of such Subsequent Triggering Event (whether on
its own behalf or on behalf of any subsequent holder of this Option (or part
thereof) or any of the shares of Common Stock issued pursuant hereto), promptly
prepare, file and keep current a shelf registration statement under the 1933 Act
covering this Option and any shares issued and issuable pursuant to this Option
and shall use its reasonable best efforts to cause such registration statement
to become effective and remain current in order to permit the sale or other
disposition of this Option and any shares of Common Stock issued upon total or
partial exercise of this Option ("Option Shares") in accordance with any plan of
disposition requested by Grantee. Issuer will use its reasonable best efforts to
cause such registration statement first to become effective and then to remain
effective for such period not in excess of 180 days from the day such
registration statement first becomes effective or such shorter time as may be
reasonably necessary to effect such sales or other dispositions. Grantee shall
have the right to demand two such registrations. The foregoing notwithstanding,
if, at the time of any request by Grantee for registration of the Option or
Option Shares as provided above, Issuer is in registration with respect to an
underwritten public offering of shares of Common Stock, and if in the good faith
judgment of the managing underwriter or managing underwriters, or, if none, the
sole underwriter or underwriters, of such offering the inclusion of the Holder's
Option or Option Shares would interfere with the successful marketing of the
shares of Common Stock offered by Issuer, the number of Option Shares otherwise
to be covered in the registration statement contemplated hereby may be reduced;
and provided, however, that after any such required reduction the number of
Option Shares to be included in such offering for the account of the Holder
shall constitute at least 25% of the total number of shares to be sold by the
Holder and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then the Issuer shall file a registration statement for the
balance as promptly as practical and no reduction shall thereafter occur. Each
such Holder shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder. If requested by
any such Holder in connection with such registration, Issuer shall become a
party to any 

                                      -8-
<PAGE>

underwriting agreement relating to the sale of such shares, but only to the
extent of obligating itself in respect of representations, warranties,
indemnities and other agreements customarily included in secondary offering
underwriting agreements for the Issuer. Upon receiving any request under this
Section 6 from any Holder, Issuer agrees to send a copy thereof to any other
person known to Issuer to be entitled to registration rights under this Section
6, in each case by promptly mailing the same, postage prepaid, to the address of
record of the persons entitled to receive such copies. Notwithstanding anything
to the contrary contained herein, in no event shall Issuer be obligated to
effect more than two registrations pursuant to this Section 6 by reason of the
fact that there shall be more than one Grantee as a result of any assignment or
division of this Agreement.

                  7. (a) From and after a Repurchase Event (as defined below),
(i) following a request of the Holder, delivered prior to an Exercise
Termination Event, Issuer (or any successor thereto) shall repurchase the Option
from the Holder at a price (the "Option Repurchase Price") equal to the amount
by which (A) the Market/Offer Price (as defined below) exceeds (B) the Option
Price, multiplied by the number of shares for which this Option may then be
exercised (provided that, notwithstanding anything to the contrary, if the
Issuer shall not have sufficient additional authorized but unissued shares or
treasury shares of Common Stock so that the Option may be exercised in full, the
Option Repurchase Price shall be calculated as if there were sufficient shares
which were authorized but unissued so that the Option could be exercised in
full) and (ii) at the request of the owner of Option Shares from time to time
(the "Owner"), delivered within 90 days of such occurrence (or such later period
as provided in Section 10), Issuer shall repurchase such number of the Option
Shares from the Owner as the Owner shall designate at a price (the "Option Share
Repurchase Price") equal to the Market/Offer Price multiplied by the number of
Option Shares so designated. The term "Market/Offer Price" shall mean the
highest of (i) the price per share of Common Stock at which a tender offer or
exchange offer therefor has been made, (ii) the price per share of Common Stock
to be paid by any third party pursuant to an agreement with Issuer, (iii) the
highest closing price for shares of Common Stock within the six-month period
immediately preceding the date the Holder gives notice of the required
repurchase of this Option or the Owner gives notice of the required repurchase
of Option Shares, as the case may be, or (iv) in the event of a sale of 25% or
more of the assets of the Issuer and its Significant Subsidiaries taken as a
whole, the sum of the price paid in such sale for such assets and the current
market value of the remaining assets of Issuer as determined by a 

                                      -9-
<PAGE>

nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to the Issuer, divided by
the number of shares of Common Stock of Issuer outstanding at the time of such
sale. In determining the Market/Offer Price, the value of consideration other
than cash shall be determined by a nationally recognized investment banking firm
selected by the Holder or Owner, as the case may be, and reasonably acceptable
to the Issuer.

                  (b) The Holder and the Owner, as the case may be, may exercise
its right to require Issuer to repurchase the Option and any Option Shares
pursuant to this Section 7 by surrendering for such purpose to Issuer, at its
principal office this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that the Holder
or the Owner, as the case may be, elects to require Issuer to repurchase this
Option and/or the Option Shares in accordance with the provisions of this
Section 7. Within the latter to occur of (x) five business days after the
surrender of the Option and/or certificates representing Option Shares and the
receipt of such notice or notices relating thereto and (y) the time that is
immediately prior to the occurrence of a Repurchase Event, Issuer shall deliver
or cause to be delivered to the Holder the Option Repurchase Price and/or to the
Owner the Option Share Repurchase Price therefor or the portion thereof, if any,
that Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that Issuer is prohibited under applicable
law or regulation from repurchasing the Option and/or the Option Shares in full,
Issuer shall immediately so notify the Holder and/or the Owner and thereafter
deliver or cause to be delivered, from time to time, to the Holder and/or the
Owner, as appropriate, the portion of the Option Repurchase Price and the Option
Share Repurchase Price, respectively, that it is no longer prohibited from
delivering, within five business days after the date on which Issuer is no
longer so prohibited; provided, however, that if Issuer at any time after
delivery of a notice of repurchase pursuant to paragraph (b) of this Section 7
is prohibited under applicable law or regulation from delivering to the Holder
and/or the Owner, as appropriate, the Option Repurchase Price and the Option
Share Repurchase Price, respectively, in full (and Issuer hereby undertakes to
use its reasonable best efforts to obtain all required regulatory and legal
approvals and to file any required notices, in each case as promptly as
practicable in order to accomplish such repurchase), the Holder or Owner may
revoke its notice of repurchase of the Option or the Option Shares either in
whole or to the extent of the prohibition, whereupon, in the latter case, Issuer
shall 

                                      -10-
<PAGE>

promptly (i) deliver to the Holder and/or the Owner, as appropriate, that
portion of the Option Repurchase Price or the Option Share Repurchase Price that
Issuer is not prohibited from delivering; and (ii) deliver, as appropriate,
either (A) to the Holder, a new Stock Option Agreement evidencing the right of
the Holder to purchase that number of shares of Common Stock obtained by
multiplying the number of shares of Common Stock for which the surrendered Stock
Option Agreement was exercisable at the time of delivery of the notice of
repurchase by a fraction, the numerator of which is the Option Repurchase Price
less the portion thereof theretofore delivered to the Holder and the denominator
of which is the Option Repurchase Price, or (B) to the Owner, a certificate for
the Option Shares it is then so prohibited from repurchasing.

                  (d) For purposes of this Section 7, a Repurchase Event shall
be deemed to have occurred (i) upon the consummation of any merger,
consolidation or similar transaction involving Issuer or any purchase, lease or
other acquisition of 25% or more of the assets of Issuer and its Significant
Subsidiaries taken as a whole, other than any such transaction which would not
constitute an Acquisition Transaction pursuant to the provisos to Section
2(b)(i) hereof or (ii) upon the acquisition by any person of beneficial
ownership of 50% or more of the then outstanding shares of Common Stock,
provided that no such event shall constitute a Repurchase Event unless a
Subsequent Triggering Event shall have occurred prior to an Exercise Termination
Event. The parties hereto agree that Issuer's obligations to repurchase the
Option or Option Shares under this Section 7 shall not terminate upon the
occurrence of an Exercise Termination Event unless no Subsequent Triggering
Event shall have occurred prior to the occurrence of an Exercise Termination
Event.

                  8. (a) In the event that prior to an Exercise Termination
Event, Issuer shall enter into an agreement other than the Merger Agreement (i)
to consolidate with or merge into any person, other than Grantee or one of its
Subsidiaries, and shall not be the continuing or surviving corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one of
its Subsidiaries, to merge into Issuer and Issuer shall be the continuing or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Common Stock shall be changed into or exchanged for stock or other
securities of any other person or cash or any other property or the then
outstanding shares of Common Stock shall after such merger represent less than
50% of the outstanding voting shares and voting share equivalents of the merged
company, or (iii) to sell or otherwise transfer all or substantially all of its
assets to any person, other than Grantee or one of its 

                                      -11-
<PAGE>

Subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provision so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option (the "Substitute
Option"), at the election of the Holder, of either (x) the Acquiring Corporation
(as hereinafter defined) or (y) any person that controls the Acquiring
Corporation.

                  (b) The following terms have the meanings indicated:

                           (1) "Acquiring Corporation" shall mean (i) the
         continuing or surviving corporation of a consolidation or merger with
         Issuer (if other than Issuer), (ii) Issuer in a merger in which Issuer
         is the continuing or surviving person, or (iii) the transferee of all
         or substantially all of Issuer's assets.

                           (2) "Substitute Common Stock" shall mean the common
         stock issued by the issuer of the Substitute Option upon exercise of
         the Substitute Option.

                           (3) "Assigned Value" shall mean the Market/Offer
         Price, as defined in Section 7.

                           (4) "Average Price" shall mean the average closing
         price of a share of the Substitute Common Stock for the one year
         immediately preceding the consolidation, merger or sale in question,
         but in no event higher than the closing price of the shares of
         Substitute Common Stock on the day preceding such consolidation, merger
         or sale; provided that if Issuer is the issuer of the Substitute
         Option, the Average Price shall be computed with respect to a share of
         common stock issued by the person merging into Issuer or by any company
         which controls or is controlled by such person, as the Holder may
         elect.

                  (c) The Substitute Option shall have the same terms as the
Option, provided, that if the terms of the Substitute Option cannot, for legal
reasons, be the same as the Option, such terms shall be as similar as possible
and in no event less advantageous to the Holder. The issuer of the Substitute
Option shall also enter into an agreement with the then Holder or Holders of the
Substitute Option in substantially the same form as this Agreement, which shall
be applicable to the Substitute Option, upon surrender of this Agreement.

                  (d) The Substitute Option shall be exercisable for such number
of shares of Substitute Common Stock as is equal to 

                                      -12-
<PAGE>

the Assigned Value multiplied by the number of shares of Common Stock for which
the Option is then exercisable, divided by the Average Price. The exercise price
of the Substitute Option per share of Substitute Common Stock shall then be
equal to the Option Price multiplied by a fraction, the numerator of which shall
be the number of shares of Common Stock for which the Option is then exercisable
and the denominator of which shall be the number of shares of Substitute Common
Stock for which the Substitute Option is exercisable.

                  (e) In no event, pursuant to any of the foregoing paragraphs,
shall the Substitute Option be exercisable for more than 19.9% of the shares of
Substitute Common Stock outstanding prior to exercise of the Substitute Option.
In the event that the Substitute Option would be exercisable for more than 19.9%
of the shares of Substitute Common Stock outstanding prior to exercise but for
this clause (e), the issuer of the Substitute Option (the "Substitute Option
Issuer") shall make a cash payment to Holder equal to the excess of (i) the
value of the Substitute Option without giving effect to the limitation in this
clause (e) over (ii) the value of the Substitute Option after giving effect to
the limitation in this clause (e). This difference in value shall be determined
by a nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to the Acquiring
Corporation.

                  (f) Issuer shall not enter into any transaction described in
subsection (a) of this Section 8 unless the Acquiring Corporation and any person
that controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder.

                  9. (a) At the request of the holder of the Substitute Option
(the "Substitute Option Holder"), the Substitute Option Issuer shall repurchase
the Substitute Option from the Substitute Option Holder at a price (the
"Substitute Option Repurchase Price") equal to (x) the amount by which (i) the
Highest Closing Price (as hereinafter defined) exceeds (ii) the exercise price
of the Substitute Option, multiplied by the number of shares of Substitute
Common Stock for which the Substitute Option may then be exercised plus (y)
Grantee's reasonable out-of-pocket expenses (to the extent not previously
reimbursed), and at the request of the owner (the "Substitute Share Owner") of
shares of Substitute Common Stock (the "Substitute Shares"), the Substitute
Option Issuer shall repurchase the Substitute Shares at a price (the "Substitute
Share Repurchase Price") equal to (x) the Highest Closing Price multiplied by
the number of Substitute Shares so designated plus (y) Grantee's reasonable
Out-of-Pocket Expenses (to the extent not previously reimbursed). The term
"Highest 

                                      -13-
<PAGE>

Closing Price" shall mean the highest closing price for shares of Substitute
Common Stock within the six-month period immediately preceding the date the
Substitute Option Holder gives notice of the required repurchase of the
Substitute Option or the Substitute Share Owner gives notice of the required
repurchase of the Substitute Shares, as applicable.

                  (b) The Substitute Option Holder and the Substitute Share
Owner, as the case may be, may exercise its respective right to require the
Substitute Option Issuer to repurchase the Substitute Option and the Substitute
Shares pursuant to this Section 9 by surrendering for such purpose to the
Substitute Option Issuer, at its principal office, the agreement for such
Substitute Option (or, in the absence of such an agreement, this Agreement) and
certificates for Substitute Shares accompanied by a written notice or notices
stating that the Substitute Option Holder or the Substitute Share Owner, as the
case may be, elects to require the Substitute Option Issuer to repurchase the
Substitute Option and/or the Substitute Shares in accordance with the provisions
of this Section 9. As promptly as practicable, and in any event within five
business days after the surrender of the Substitute Option and/or certificates
representing Substitute Shares and the receipt of such notice or notices
relating thereto, the Substitute Option Issuer shall deliver or cause to be
delivered to the Substitute Option Holder the Substitute Option Repurchase Price
and/or to the Substitute Share Owner the Substitute Share Repurchase Price
therefor or, in either case, the portion thereof which the Substitute Option
Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that the Substitute Option Issuer is
prohibited under applicable law or regulation from repurchasing the Substitute
Option and/or the Substitute Shares in part or in full, the Substitute Option
Issuer following a request for repurchase pursuant to this Section 9 shall
immediately so notify the Substitute Option Holder and/or the Substitute Share
Owner and thereafter deliver or cause to be delivered, from time to time, to the
Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the
portion of the Substitute Share Repurchase Price, respectively, which it is no
longer prohibited from delivering, within five business days after the date on
which the Substitute Option Issuer is no longer so prohibited; provided,
however, that if the Substitute Option Issuer is at any time after delivery of a
notice of repurchase pursuant to subsection (b) of this Section 9 prohibited
under applicable law or regulation from delivering to the Substitute Option
Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option
Repurchase Price and the Substitute Share Repurchase 

                                      -14-
<PAGE>

Price, respectively, in full (and the Substitute Option Issuer shall use its
best efforts to obtain all required regulatory and legal approvals, in each case
as promptly as practicable in order to accomplish such repurchase), the
Substitute Option Holder or Substitute Share Owner may revoke its notice of
repurchase of the Substitute Option or the Substitute Shares either in whole or
to the extent of the prohibition, whereupon, in the latter case, the Substitute
Option Issuer shall promptly (i) deliver to the Substitute Option Holder or
Substitute Share Owner, as appropriate, that portion of the Substitute Option
Repurchase Price or the Substitute Share Repurchase Price that the Substitute
Option Issuer is not prohibited from delivering; and (ii) deliver, as
appropriate, either (A) to the Substitute Option Holder, a new Substitute Option
evidencing the right of the Substitute Option Holder to purchase that number of
shares of the Substitute Common Stock obtained by multiplying the number of
shares of the Substitute Common Stock for which the surrendered Substitute
Option was exercisable at the time of delivery of the notice of repurchase by a
fraction, the numerator of which is the Substitute Option Repurchase Price less
the portion thereof theretofore delivered to the Substitute Option Holder and
the denominator of which is the Substitute Option Repurchase Price, or (B) to
the Substitute Share Owner, a certificate for the Substitute Common Shares it is
then so prohibited from repurchasing.

                  10. The 90-day period for exercise of certain rights under
Sections 2, 6, 7 and 13 shall be extended: (i) to the extent necessary to obtain
all regulatory approvals for the exercise of such rights, and for the expiration
of all statutory waiting periods; (ii) to the extent necessary to avoid
liability under Section 16(b) of the 1934 Act by reason of such exercise and
(iii) during any period in which Grantee is precluded from exercising such
rights due to an injunction or other legal restriction, plus in each case such
additional period as is reasonably necessary for the exercise of such rights
promptly following the obtaining of such approvals or the expiration of such
periods.

                  11. Issuer hereby represents and warrants to Grantee as
follows:

                  (a) Issuer has full corporate power and authority to execute
and deliver this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board of Directors of Issuer and no other corporate proceedings on the part of
Issuer are necessary to authorize this Agreement 

                                      -15-
<PAGE>

or to consummate the transactions so contemplated. This Agreement has been duly
and validly executed and delivered by Issuer.

                  (b) Subject to Section 3, Issuer has taken all necessary
corporate action to authorize and reserve and to permit it to issue, and at all
times from the date hereof through the termination of this Agreement in
accordance with its terms will have reserved for issuance upon the exercise of
the Option, that number of shares of Common Stock equal to the maximum number of
shares of Common Stock at any time and from time to time issuable hereunder, and
all such shares, upon issuance pursuant hereto, will be duly authorized, validly
issued, fully paid, nonassessable (subject to Section 180.0622(2)(b) of the
WGBL), and will be delivered free and clear of all claims, liens, encumbrance
and security interests and not subject to any preemptive rights.

                  (c) Issuer has taken all action (including amending the Rights
Agreement) so that the entering into of this Option Agreement, the acquisition
of shares of Common Stock hereunder and the other transactions contemplated
hereby do not and will not result in the grant of any rights to any person under
the Rights Agreement or enable or require the Rights to be exercised,
distributed or triggered.

                  12. Grantee hereby represents and warrants to Issuer that:

                  (a) Grantee has all requisite corporate power and authority to
enter into this Agreement and, subject to any approvals or consents referred to
herein, to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by all necessary corporate action on the part
of Grantee. This Agreement has been duly executed and delivered by Grantee.

                  (b) The Option is not being, and any shares of Common Stock or
other securities acquired by Grantee upon exercise of the Option will not be,
acquired with a view to the public distribution thereof and will not be
transferred or otherwise disposed of except in a transaction registered or
exempt from registration under the Securities Act.

                  13. Neither of the parties hereto may assign any of its rights
or obligations under this Option Agreement or the Option created hereunder to
any other person, without the express written consent of the other party, except
that in the event a 

                                      -16-
<PAGE>

Subsequent Triggering Event shall have occurred prior to an Exercise Termination
Event, Grantee, subject to the express provisions hereof, may assign in whole or
in part its rights and obligations hereunder within 90 days following such
Subsequent Triggering Event (or such later period as provided in Section 10);
provided, however, that until the date 15 days following the date on which the
Federal Reserve Board approves an application by Grantee under the BHCA to
acquire the shares of Common Stock subject to the Option, Grantee may not assign
its rights under the Option except in (i) a widely dispersed public
distribution, (ii) a private placement in which no one party acquires the right
to purchase in excess of 2% of the voting shares of Issuer, (iii) an assignment
to a single party (e.g., a broker or investment banker) for the purpose of
conducting a widely dispersed public distribution on Grantee's behalf, or (iv)
any other manner approved by the Federal Reserve Board.

                  14. Each of Grantee and Issuer will use its reasonable best
efforts to make all filings with, and to obtain consents of, all third parties
and governmental authorities necessary to the consummation of the transactions
contemplated by this Agreement, including without limitation making application
to list the shares of Common Stock issuable hereunder on the New York Stock
Exchange upon official notice of issuance and applying to the Federal Reserve
Board under the BHCA for approval to acquire the shares issuable hereunder, but
Grantee shall not be obligated to apply to state banking authorities for
approval to acquire the shares of Common Stock issuable hereunder until such
time, if ever, as it deems appropriate to do so.

                  15. Grantee in its sole discretion may, at any time during
which Issuer would be required to repurchase the Option or any Option Shares
pursuant to Section 7, surrender the Option (together with any Option Shares
issued to and then owned by the Holder) to Issuer in exchange for a cash payment
equal to the Surrender Price (as defined herein); provided, however, that
Grantee may not exercise its rights pursuant to this Section 15 if Issuer has
previously repurchased the Option (or any portion thereof) or any Option Shares
pursuant to Section 7. The "Surrender Price" shall be equal to (i) $300 million,
plus (ii) if applicable, the aggregate purchase price previously paid pursuant
hereto by Grantee with respect to any Option Shares, minus (iii) if applicable,
the excess of (A) the net cash, if any, received by Grantee pursuant to the
arm's-length sale of Option Shares (or any other securities into which such
Option Shares were converted or exchanged) to any party not affiliated with
Grantee, over (B) the purchase price paid by Grantee with respect to such Option
Shares.

                                      -17-
<PAGE>

                  (b) Grantee may exercise its right to surrender the Option and
any Option Shares pursuant to this Section 15 by surrendering for such purchase
to Issuer, at its principal office, this Agreement, together with certificates
for Option Shares, if any, accompanied by a written notice stating (i) that
Grantee elects to surrender the Option and Option Shares, if any, in accordance
with the provisions of this Section 15 and (ii) the Surrender Price. Within two
business days after the surrender of the Option and the Option Shares, if
applicable, Issuer shall deliver or cause to be delivered to Grantee the
Surrender Price.

                  (c) To the extent that the Issuer is prohibited under
applicable law or regulation from paying the Surrender Price to Grantee in full,
Issuer shall immediately so notify Grantee and thereafter deliver, or cause to
be delivered, from time to time, to Grantee, that portion of the Surrender Price
that Issuer is not or no longer prohibited from paying, within two business days
after the date on which Issuer is no longer so prohibited; provided, however,
that if Issuer at any time after delivery of a notice of Surrender pursuant to
Section 15(b) is prohibited under applicable law or regulation from paying to
Grantee the Surrender Price in full, (i) Issuer shall (A) use its reasonable
best efforts to obtain all required regulatory and legal approvals and to file
any required notices as promptly as practicable in order to make such payments,
(B) within two business days of the submission or receipt of any documents
relating to any such regulatory and legal approvals, provide Grantee with copies
of the same, and (C) keep Grantee advised of both the status of any such request
for regulatory and legal approvals and any discussions with any relevant
regulatory or other third party reasonably related to the same, and (ii) Grantee
may revoke such notice of surrender by delivery of a notice of revocation, the
Exercise Termination Event shall be extended to a date six months from the date
on which the Exercise Termination Event would have occurred if not for the
provisions of this Section 15(c) (during which period Grantee may exercise any
of its rights hereunder, including any and all rights pursuant to this Section
15).

                  (d) Grantee shall have rights substantially identical to those
set forth in paragraphs (a), (b) and (c) of this Section 15 with respect to the
Substitute Option and the Substitute Option Issuer during any period in which
the Substitute Option Issuer would be required to repurchase the Substitute
Option pursuant to Section 9.

                  16. The parties hereto acknowledge that damages would be an
inadequate remedy for a breach of this Agreement by either party hereto and that
the obligations of the parties hereto shall 

                                      -18-
<PAGE>

be enforceable by either party hereto through injunctive or other equitable
relief.

                  17. If any term, provision, covenant or restriction contained
in this Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or invalidated. If for any reason such court or regulatory agency determines
that the Holder is not permitted to acquire, or Issuer is not permitted to
repurchase pursuant to Section 7, the full number of shares of Common Stock
provided in Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5
hereof), it is the express intention of Issuer (which shall be binding on the
Substitute Option Issuer) to allow the Holder to acquire or to require Issuer or
Substitute Option Issuer to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof.

                  18. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered
in person, by telecopy or by registered or certified mail (postage prepaid,
return receipt requested) at the respective addresses of the parties set forth
in the Merger Agreement.

                  19. This Agreement shall be governed by and construed in
accordance with the laws of the State of Wisconsin, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof
(except to the extent that mandatory provisions of federal law apply).

                  20. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of which
shall constitute one and the same agreement.

                  21. Except as otherwise expressly provided herein, each of the
parties hereto shall bear and pay all costs and expenses incurred by it or on
its behalf in connection with the transactions contemplated hereunder, including
fees and expenses of its own financial consultants, investment bankers,
accountants and counsel.

                  22. Except as otherwise expressly provided herein or in the
Merger Agreement, this Agreement contains the entire agreement between the
parties with respect to the transactions contemplated hereunder and supersedes
all prior arrangements or understandings with respect thereof, written or oral.
The terms 

                                      -19-
<PAGE>

and conditions of this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assigns.
Nothing in this Agreement, expressed or implied, is intended to confer upon any
party, other than the parties hereto, and their respective successors except as
assigns, any rights, remedies, obligations or liabilities under or by reason of
this Agreement, except as expressly provided herein.

                  23. Capitalized terms used in this Agreement and not defined
herein shall have the meanings assigned thereto in the Merger Agreement.

                  IN WITNESS WHEREOF, each of the parties has caused this
Agreement to be executed on its behalf by its officers thereunto duly
authorized, all as of the date first above written.

              MERGE, CREATING $38 BILLION MIDWEST BANKING FRANCHISE
              -----------------------------------------------------

     $7.2 BILLION TRANSACTION WILL PROVIDE 12 PERCENT EPS ACCRETION IN 2000

         CINCINNATI and MILWAUKEE (July 1,1998) -- Star Banc Corporation
(NYSE:STB) and Firstar Corporation (NYSE:FSR) today announced that they have
signed a definitive agreement to merge through an exchange of shares valued at
approximately $7.2 billion.

         The merger would create the 21st largest bank holding company in the
United States, with assets of more than $38 billion, and deposits of $28
billion. The combined company will provide a full line of consumer banking,
commercial banking and trust and investment management services and products to
more than 3 million customers through its 14,000 employees and 720 branch
locations in eight Midwest states and Arizona, plus trust operations in Florida.

         Under the terms of the agreement, Firstar shareholders will receive a
tax-free exchange of 0.76 shares of common stock of the combined company for
each share of Firstar common stock. Shareholders of Star Banc will retain one
share of common stock in the combined company for each Star Banc share. Based on
Star Banc's closing stock price on June 30, 1998, this represents a price of
$48.55 for each Firstar share.

         The combined company will be known as Firstar Corporation. Its
corporate headquarters will be located in Milwaukee, and its consumer banking
and specialized lending operations will be headquartered in Cincinnati. Roger L.
Fitzsimonds, chairman and chief executive officer of Firstar, will become
chairman of the board of the new company, and Jerry A. Grundhofer, chairman,
president and chief executive officer of Star Banc, will become president and
chief executive officer. The board of directors will comprise 18 representatives
of Star Banc and 14 representatives of Firstar.

         "Star Banc and Firstar are two successful banks with long and proud
histories that will now move up to the next plateau in financial services.
Together, that's what we will do," said Grundhofer. "Putting together these two
first-class banks creates a leading provider of financial services in the
Midwest region, with the opportunity to offer greater financial strength, a
broader range of products and services, stronger technology and greater
efficiency to our customers and communities. This merger will provide unmatched
economic benefits for shareholders of both companies and will position the
combined company strategically to operate on a new and higher level of banking
going forward."

         "We are delighted to be partnering with a bank so completely compatible
with our own," says Fitzsimonds. "Firstar and Star Banc have strong community
orientations, complementary high-tech quality products, and a shared commitment
to outstanding customer service. Each of us has products, skills and resources
to bring to the other. We look forward to a seamless integration of our two
companies into a single regional banking leader and corporate citizen."

         The transaction provides Firstar shareholders a premium of 27 percent
over the value of their shares on June 30, 1998. It is estimated that the
combined company expects to incur pre-tax merger-related restructuring charges
of $325 million in 1998. The transaction, which will be accounted for as a
pooling of interests, is expected to be 5 percent accretive to the combined
company's earnings per share in 1999, and 12 percent accretive in 2000.

         After the closing, the combined company expects to pay dividends at an
annual rate of $1.20 per common share. This approximates a continuation of the
current dividend rate paid on Firstar shares, adjusted for the exchange ratio,
which would represent an increase of 30 percent on the current dividend rate
paid on Star Banc shares.

         Star Banc and Firstar estimate that they will reduce their expenses by
$174 million, with half of this saving achieved in 1999, and the remainder in
2000. This cost saving represents 15 percent of the two companies' current
expense base, and would bring the combined company into line with Star Banc's
current efficiency ratio. The cost saving opportunities include centralization
of corporate activities, consolidation of data processing and operations,
optimization of commercial banking, retail branches and alternative delivery
channels for bank products and services, improvements in technology, and
reconfiguration of mortgage, credit card and asset management businesses.

         Additionally, the companies believe there is significant opportunity
for revenue synergies resulting from product cross-selling, accelerated consumer
loan growth, new product introduction, and implementation of Star Banc's highly
successful incentive-based compensation program throughout the combined company.
This program provides all employees with incentive pay linked to selected
measures of shareholder value. The companies project these revenue enhancements
at $42 million annually, with one-half to be realized in 1999 and the rest in
2000.

         The two companies have no geographical overlap, and no merger-related
branch closings are planned. As with any merger of this magnitude, some job loss
at both organizations will be unavoidable, primarily in redundant headquarters
and administrative positions. Customer-contact positions will be virtually
unaffected. The companies plan to minimize actual job loss through normal
attrition, voluntary separation programs and redeployment of employees into
other positions and locations.

         "When companies merge, customers must come first," said Fitzsimonds.
"Together, we have significant, successful experience in business integration
that minimizes disruption to customers. We will make this transition a smooth
and comfortable one." Customers of the merged company will have access to 720
branches, more than 1,400 ATM's and a broad range of electronic banking, PC
banking and Internet banking products and services.

         "These banks have deep roots in both Cincinnati and Milwaukee, and we
intend to be leading corporate citizens in both cities long after our merger is
complete," said Grundhofer. "In this decade, Star Banc has become synonymous
with superior service and active community participation in Cincinnati and all
the communities we serve. We intend to maintain our strong physical presence in
our historical home town, to continue to improve the breadth and quality of our
service to customers, and to maintain our commitment to community reinvestment,
civic involvement and corporate philanthropy."

         The new company will have three vice chairmen who will all report to
Grundhofer: John A. Becker, currently president and chief operating officer of
Firstar, who will be the chief operating officer of the combined company; David
M. Moffett, currently executive vice president and chief financial officer of
Star Banc, who will be the chief financial officer of the combined company; and
Richard K. Davis, currently executive vice president of Star Banc, who will be
responsible for consumer banking.

         The combined company's consumer banking operations, headed by Davis,
will be headquartered in Cincinnati. Davis will also be responsible for all
banking operations in the Greater Cincinnati market.

         Star currently holds an outstanding Community Reinvestment Act (CRA)
rating, while Firstar Bank Milwaukee, N.A., is rated satisfactory. Star and
Firstar have committed to achieving an outstanding rating after the merger. Star
has also reconfirmed its new $5.15 billion community development initiative,
which was announced February 1998.

         The transaction, which was approved by the boards of both companies, is
subject to normal shareholder and regulatory approvals. In connection with the
merger agreement, Star Banc and Firstar have each granted the other an option
for 19.9 percent of its common shares. The transaction is expected to close in
the fourth quarter of 1998 or early in the first quarter of 1999.
