                            COMMON STOCK, $1.25 PAR VALUE
                                     ____________

   
    This Proxy Statement/Prospectus (the "Proxy Statement/Prospectus"), is 
being furnished to holders of common stock, $1.00 par value ("Zappco Common 
Stock"), of Zappco, Inc., a Minnesota corporation ("Zappco"), in connection 
with the solicitation of proxies by the Board of Directors of Zappco for use 
at a special meeting of such holders (the "Special Meeting") to be held on 
December 11, 1997, commencing at 4:30 p.m., local time, and at any 
adjournment or postponement thereof.  At the Special Meeting, holders of 
Zappco Common Stock will be asked to consider and act upon (i) a proposal to 
approve the Agreement and Plan of Merger, dated September 12, 1997 (the 
"Merger Agreement"), by and among U.S. Bancorp, a Delaware corporation 
("USB"), and Zappco, and the transactions contemplated thereby, pursuant to 
which, among other things, Zappco would be acquired by USB by means of a 
merger of Zappco with and into USB (the "Merger") and (ii) a proposal to 
approve payments of any "excess parachute payments" within the meaning of 
Section 280G of the Internal Revenue Code of 1986, as amended (the "280G 
Payments").  A copy of the Merger Agreement is attached hereto as APPENDIX A 
and is incorporated herein by reference.
    
   
    Pursuant to the Merger Agreement, each issued and outstanding share of 
Zappco Common Stock will be converted into the right to receive a number of 
shares of the common stock, par value $1.25 per share, of USB ("USB Common 
Stock") equal to $68 million (the "Purchase Price," as may be adjusted 
pursuant to the Merger Agreement and described herein) divided by the average 
of the closing prices of USB Common Stock as quoted on the New York Stock 
Exchange (the "NYSE") for the ten consecutive trading days ending with the 
day preceding the date on which the Merger becomes effective, divided by the 
number of shares of Zappco Common Stock outstanding on the date on which the 
Merger becomes effective.  Any fractional share of USB Common Stock will be 
paid in cash. Shares of USB Common Stock issued pursuant to the Merger, plus 
cash paid in lieu of fractional shares, constitute the "Merger 
Consideration."  See "The Merger--Terms of the Merger; Consideration to be 
Received by Zappco Shareholders."  The outstanding shares of USB Common Stock 
are, and it is a condition to the consummation of the  Merger  that  the  
shares  of USB  Common Stock to be issued in the Merger be, listed on the 
NYSE under the symbol "USB." The last reported sale price of USB Common Stock 
on the NYSE Composite Tape on November 6, 1997 was $104.19 per share, and the 
average closing price for the ten consecutive trading days ending on such 
date was $102.18 per share.

                                     ____________

      THESE SECURITIES HAVE NOT BEEN APPROVED OR  DISAPPROVED BY THE SECURITIES
          AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS
            THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
               COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
                   PROXY STATEMENT/PROSPECTUS.  ANY REPRESENTATION
                        TO THE CONTRARY IS A CRIMINAL OFFENSE.

       THE SHARES OF USB COMMON STOCK OFFERED HEREBY ARE NOT SAVINGS ACCOUNTS,
         DEPOSITS OR OTHER OBLIGATIONS OF ANY BANK OR SAVINGS ASSOCIATION AND
            ARE NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION,
                  BANK INSURANCE FUND, SAVINGS ASSOCIATION INSURANCE
                        FUND OR ANY OTHER GOVERNMENTAL AGENCY.
   
             THE DATE OF THIS PROXY STATEMENT/PROSPECTUS IS NOVEMBER 7, 1997.

Based on such average closing price, and assuming no adjustment to the 
Purchase Price, the number of shares of USB Common Stock issued in exchange 
for each share of Zappco Common Stock would be 42.01.  THERE CAN BE NO 
ASSURANCE AS TO THE MARKET PRICE OF THE USB COMMON STOCK AT ANY TIME BEFORE 
THE EFFECTIVE DATE OR AS TO THE MARKET PRICE OF THE USB COMMON STOCK AT ANY 
TIME THEREAFTER.
    

    For additional information regarding the terms of the Merger, see the 
Merger Agreement attached as APPENDIX A hereto and "The Merger" herein.

    Consummation of the Merger is conditioned upon, among other things, 
receipt of all required shareholder and regulatory approvals.  If there are 
not sufficient votes at the time of the Special Meeting to approve the Merger 
Agreement, the Zappco shareholders may be asked to approve adjournment of the 
Special Meeting to permit further solicitation of proxies.  See "Adjournment 
of the Special Meeting" and "The Merger--Regulatory Approvals Required."

SECTIONS 302A.471 AND 302A.473 OF THE MINNESOTA BUSINESS CORPORATION ACT (THE

THE PROPOSED MERGER

    The Agreement and Plan of Merger, dated September 12, 1997, among USB and 
Zappco, provides for the merger of Zappco with and into USB, with USB as the 
surviving corporation.  Assuming the Merger Agreement is approved by the 
shareholders of Zappco, the Merger will become effective upon the filing of an 
appropriate certificate of merger and articles of merger with the Secretaries 
of State in the States of Delaware and Minnesota, respectively (the "Effective 
Date").  Upon consummation of the Merger, each issued and outstanding share of 
Zappco Common Stock will be converted into the right to receive the Merger 
Consideration.  If the Merger is consummated, Zappco shareholders will no 
longer


                                       4

<PAGE>

hold any interest in Zappco other than through their interest in USB 
Common Stock received in the Merger.  Each outstanding share of USB capital 
stock will remain outstanding and unchanged following the Merger.  See "The 
Merger--Terms of the Merger; Consideration to be Received by Zappco 
Shareholders."

    The Merger is subject to a number of conditions, including the receipt of 
required regulatory and shareholder approvals.  See "The Merger--Conditions to 
Consummation of the Merger."

    Pursuant to the Merger Agreement, the certificate of incorporation and 
bylaws of USB as in effect prior to the Effective Date will be the certificate 
of incorporation and bylaws of USB, as the surviving corporation in the Merger, 
after the Effective Date.  In addition, the officers and directors of USB prior 
to the Effective Date will be the officers and directors of USB, as the 
surviving corporation in the Merger, after the Effective Date until their 
successors are duly elected or appointed and qualified.

SPECIAL MEETING OF ZAPPCO SHAREHOLDERS

   
    The Special Meeting to consider and vote upon the Merger Agreement and 
the 280G Payments will be held in St. Cloud, Minnesota, at Zappco's principal 
executive offices, on Thursday, December 11, 1997 at 4:30 p.m.  local time.  
Only holders of record of Zappco Common Stock and participants in Zappco's 
Employee Stock Ownership Plan at the close of business on October 31, 1997 
(the "Record Date"), will be entitled to notice of and to vote at the Special 
Meeting.  At the close of business on the Record Date, there were outstanding 
and entitled to vote 15,842 shares of Zappco Common Stock.  Each share of 
Zappco Common Stock is entitled to one vote on the Merger Agreement.  See 
"Information Concerning the Special Meeting."
    

VOTE REQUIRED TO APPROVE THE MERGER, THE 280G PAYMENTS AND THE ADJOURNMENT; 
QUORUM

    Pursuant to Minnesota law, approval of the Merger Agreement requires the 
affirmative vote of the holders of a majority of all shares of Zappco Common 
Stock outstanding at the Record Date.  Approval of the 280G Payments requires 
the affirmative vote of more than 75% of the voting power of all outstanding 
shares of Zappco Common Stock, excluding those shares held or constructively 
owned by the individuals (Edward J.  Zapp and John E. Leisen) whose 
compensation is being considered.  A majority of all shares of Zappco Common 
Stock outstanding and entitled to vote, represented in person or by proxy, 
will constitute a quorum for the Special Meeting.  Approval of the 
adjournment of the Special Meeting requires the affirmative vote of at least 
a majority of the outstanding shares of Zappco Common Stock represented in 
person or by proxy at the Special Meeting, even if such number of shares is 
less than a quorum.  Approval of the Merger Agreement by the shareholders of 
USB is not required under applicable law.

    It is expected that all of the 4,601 shares of Zappco Common Stock 
beneficially owned by directors and executive officers, and their affiliates, 
of Zappco at the Record Date (approximately 29.04% of the total number of 
outstanding shares of Zappco Common Stock at such date) will be voted for 
approval of the Merger Agreement and the 280G Payments (excluding shares owned 
or controlled by Edward J. Zapp and John F. Leisen who will receive such 
payments) and for adjournment of the Special Meeting under the circumstances 
described herein.  As of the Record Date, USB beneficially owned no shares of 
Zappco Common Stock, and directors and officers of USB and their affiliates 
beneficially owned no shares of Zappco Common Stock.  See "Information 
Concerning the Special Meeting--Solicitation, Voting and Revocability of 
Proxies."

RECOMMENDATION OF THE ZAPPCO BOARD OF DIRECTORS

    THE BOARD OF DIRECTORS OF ZAPPCO RECOMMENDS THAT ZAPPCO SHAREHOLDERS VOTE 
FOR APPROVAL OF THE MERGER AGREEMENT, FOR APPROVAL OF THE 280G PAYMENTS AND FOR 
APPROVAL OF ADJOURNMENT OF THE SPECIAL MEETING IF NECESSARY TO PERMIT FURTHER 
SOLICITATION OF PROXIES.

                                       5

<PAGE>

   
     The Board of Directors of Zappco recommends that the shareholders of 
Zappco approve the Merger Agreement.  The Zappco Board believes that the 
terms of the Merger Agreement are fair and that the Merger is in the best 
interests of Zappco and its shareholders.  In making its recommendation, the 
Zappco Board considered the opinion of Dain Bosworth Incorporated, financial 
advisor to the Zappco Board, dated September 12, 1997, to the effect that the 
Merger Consideration is fair to the shareholders of Zappco from a financial 
point of view.  See "The Merger--The Fairness Opinion." On November 6, 1997, 
the last sale price for USB Common Stock on the NYSE was $104.19 per share, 
and the average closing price for the ten consecutive trading days ending on 
such date was $102.18 per share. Based on such average closing price, and 
assuming no adjustment to the Purchase Price, the number of shares of USB 
Common Stock issued in exchange for each share of Zappco Common Stock would 
be 42.01.  See "The Merger--Terms of the Merger; Consideration to be Received 
by Zappco Shareholders."  The directors and executive officers of Zappco have 
unanimously indicated that they intend to vote the Zappco Common Stock that 
they hold in favor of the Merger Agreement and in favor of the 280G Payments 
(to the extent their shares can be voted for such). See "Information 
Concerning the Special Meeting--Beneficial Ownership of Zappco Common Stock." 
    

SUMMARY OF REASONS FOR THE MERGER

    The Zappco Board of Directors, after careful study and evaluation of
economic, financial, legal and market factors, believes that the Merger
Agreement is in the best interests of Zappco and Zappco's shareholders.  The
Zappco Board believes that the Merger Consideration is fair and that the USB
Common Stock has greater market liquidity than Zappco Common Stock.  See "The
Merger - Background of and Reasons for the Merger."

THE FAIRNESS OPINION

    Dain Bosworth Incorporated ("Dain"), financial advisor to Zappco, has 
rendered to the Zappco Board of Directors a written opinion dated September 12, 
1997, to the effect that, as of such date and based upon and subject to certain 
matters stated in the opinion, the Merger Consideration is fair to the holders 
of Zappco Common Stock from a financial point of view.  A copy of the opinion 
of Dain is attached hereto as APPENDIX B and should be read carefully in its 
entirety.  See "The Merger - The Fairness Opinion."

EFFECTIVE DATE OF THE MERGER

    The Merger will become effective upon the filing of an appropriate 
certificate of merger and articles of merger relating thereto with the 
Secretaries of State in the States of Delaware and Minnesota, respectively. The 
Merger Agreement provides that the parties to the Merger Agreement will cause 
the Merger to be effected as soon as practicable after receipt of all necessary 
regulatory approvals, provided that each of the conditions to consummation of 
the Merger has been satisfied or waived.  The Merger cannot become effective 
until Zappco shareholders have approved the Merger Agreement and all required 
regulatory approvals and actions have been obtained and taken.  The Merger 
Agreement may be terminated by either USB or Zappco if the Merger has not 
become effective by February 28, 1998 (unless failure to consummate the Merger 
by such date shall be due to the action or failure to act of the party seeking 
to terminate the Merger Agreement in breach of such party's obligations 
thereunder).  Accordingly, there can be no assurance as to whether or when the 
Merger will become effective.  See "The Merger--Effective Date of the Merger," 
"--Conditions to Consummation of the Merger" and "--Regulatory Approvals 
Required."

SURRENDER OF ZAPPCO COMMON STOCK CERTIFICATES

   
    In a mailing separate from this Proxy Statement/Prospectus, Zappco (or a 
representative of Zappco) will send a notice and transmittal form, with 
instructions, to each holder of Zappco Common Stock of record advising such 
holder of the procedure for surrendering his, her or its certificates 
evidencing
    

                                       6

<PAGE>

Zappco Common Stock.  Such notice and transmittal form will be sent prior to 
the Zappco Special Meeting.  Zappco shareholders should not send in their stock 
certificates until they receive such separate instructions from Zappco.  See 
"The Merger--Surrender of Zappco Common Stock Certificates."

REGULATORY APPROVALS REQUIRED

   
    The Merger is subject to the prior approval of the Board of Governors of 
the Federal Reserve System (the "Federal Reserve Board") under the Bank 
Holding Company Act.  The acquisition of control of Melrose State by USB as a 
result of the Merger is also subject to the prior approval of the Minnesota 
Commissioner of Commerce (the "Commissioner") under Section 46.048 of the 
Minnesota Statutes (the "Minnesota Change in Control Statute").  USB filed 
its notice of its intent to acquire Zappco with the Federal Reserve Board on 
October 1, 1997, and received approval of the transaction on November 3, 1997. 
USB also filed its notice of its intent to acquire Melrose State as a result 
of the Merger with the Commissioner on October 1, 1997, approval of which is 
still pending as of the date of this Proxy Statement/Prospectus.  See "The 
Merger--Regulatory Approvals Required."
    

CONDITIONS, WAIVER AND AMENDMENT AND TERMINATION

    The respective obligations of USB and Zappco to consummate the Merger are
subject to the satisfaction of certain conditions, including, among others, (i)
the receipt of all required regulatory approvals with respect to the Merger,
(ii) the approval of the Merger Agreement and 280G Payments by the requisite
vote of Zappco shareholders and (iii) certain other conditions customary in
transactions of this kind.  A failure of any of such conditions to be satisfied
would, if not waived, prevent consummation of the Merger.

    At any time before the Effective Date, any party to the Merger Agreement 
may (i) extend the time for performance of any obligations or other acts of the 
other party under the Merger Agreement or (ii) waive compliance with any of the 
agreements of the other parties or with any conditions of its own obligations 
contained in the Merger Agreement, to the extent that such obligations, 
agreements and conditions are intended for such party's own benefit.  In 
addition, the Merger Agreement may be amended by written instrument approved by 
the parties and signed on behalf of each of the parties.  See "The 
Merger--Waiver and Amendment."

    The Merger Agreement may be terminated at any time before the Effective 
Date (i) by mutual consent of USB and Zappco; (ii) by either USB or Zappco, if 
any of the conditions to such party's obligation to consummate the transaction 
contemplated in the Merger Agreement have become impossible to satisfy; or 
(iii) by either USB or Zappco, if the Effective Date is not on or before 
February 28, 1998 (unless the failure to consummate the Merger by such date 
shall be due to the action or failure to act of the party seeking to terminate 
the Merger Agreement in breach of such party's obligations thereunder).  See 
"The Merger--Termination."

LIMITATION ON NEGOTIATIONS

    The Merger Agreement provides that Zappco will not, and will cause its 
Subsidiaries and Zappco's and each Subsidiary's officers, directors, employees, 
agents and affiliates, not to, directly or indirectly, solicit, authorize, 
initiate or encourage submission of, any proposal, offer, tender offer or 
exchange offer from any person or entity (including any officers or employees 
of Zappco or its Subsidiaries) relating to any liquidation, dissolution, 
recapitalization, merger, consolidation or acquisition or purchase of all or a 
material portion of the assets or deposits of, or any equity interest in, 
Zappco or any Subsidiary, or other similar transaction or business combination 
involving Zappco or any Subsidiary, or participate in any negotiations in 
connection with or in furtherance of any of the foregoing or permit any person 
other than USB and its representatives to have any access to the facilities of, 
or furnish to any person other than USB and its representatives any non-public 
information with respect to, Zappco or any Subsidiary in connection with or in 
furtherance of any of the foregoing.  The Merger Agreement also requires Zappco 
promptly to notify USB if any such proposal or offer, or any inquiry from or 
contact with any person

                                       7

<PAGE>

with respect thereto, is made concerning any such transactions and promptly 
to provide USB with such information concerning such matters as USB may 
request.  See "The Merger--Limitation on Negotiations."

    The foregoing provisions may have the effect of discouraging competing
offers to acquire or merge with Zappco.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

    SALARY CONTINUATION AGREEMENTS.  Zappco is party to salary continuation 
agreements with Edward J. Zapp, its President and Chairman of the Board and a 
shareholder, and with John E. Leisen, its Vice President, a director and a 
shareholder.  USB has agreed to assume and be bound by the terms of such salary 
continuation agreements.  As a result of the Merger and the anticipated 
continuation of such agreements, USB and Zappco expect that Messrs. Zapp and 
Leisen will each receive an annual amount of $60,000 in salary continuation 
payments following the Merger.

   
    NONCOMPETITION AGREEMENTS.  Simultaneously with the execution of the 
Merger Agreement, each of Messrs. Zapp and Leisen entered into a 
Noncompetition Agreement with USB, pursuant to which each of Messrs. Zapp and 
Leisen will receive separate consideration to be paid by USB in an annual 
amount of $200,000 for approximately eight and seven years, respectively, 
subject to adjustment, as well as certain retiree medical benefits.  See "The 
Merger--Noncompetition Agreements."
    
   
    OFFER OF CONTINUED EMPLOYMENT.  Mr. Leisen and certain other employees of 
Zappco have been offered continued employment with USB following the 
anticipated closing of the Merger.  Mr. Leisen has been offered continued 
employment through December 31, 1998, or longer as mutually agreed upon, during 
which time Mr. Leisen will receive an annual base salary of $165,000, as well 
as benefits normally offered to eligible employees of USB.  Mr. Leisen will 
also be granted 4,000 shares of USB restricted stock, which will vest over a 
three-year period.
    

    SEVERANCE PAYMENTS.  Pursuant to the Merger Agreement, certain employees 
mutually agreed upon by USB and Zappco will enter into severance agreements 
with USB substantially in the form provided by USB to Zappco.  With respect to 
employees of Zappco or any of its Subsidiaries not subject to any other 
severance agreement, the Merger Agreement provides that USB will pay severance 
to such employees in accordance with USB's General Severance Pay Program, as 
the same may be amended from time to time.

   
    PURCHASE OF CERTAIN ASSETS.  Pursuant to the Merger Agreement, Mr. Zapp has 
agreed to purchase from Zappco, immediately prior to the Effective Date, 
certain assets of a personal and historical interest to the founding families 
(listed on a schedule to the Merger Agreement) at the book value of such assets 
as of the last day of the month preceding the month in which the Effective Date 
occurs.
    

    The foregoing interests of members of management or shareholders of Zappco 
and its affiliates in the Merger may mean that such persons have personal 
interests in the Merger which may not be identical to the interests of 
nonaffiliated shareholders.  See "The Merger--Interests of Certain Persons in 
the Merger."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES TO ZAPPCO SHAREHOLDERS

   
    Fredrikson & Byron, P.A., special counsel to Zappco, will deliver to 
Zappco an opinion of counsel, which will be based upon various 
representations and assumptions and subject to various qualifications, to the 
effect that for federal income tax purposes the Merger will qualify as a 
"reorganization" under Section 368(a) of the Internal Revenue Code of 1986, 
as amended (the "Code") and that accordingly (a) no gain or loss will be 
recognized for federal income tax purposes by USB or Zappco as a result of 
the consummation of the Merger, (b) no gain or loss will be recognized for 
federal income tax purposes by any 
    

                                       8
<PAGE>

Zappco shareholder upon the receipt of USB Common Stock for Zappco Common Stock 
in the Merger (except to the extent of any cash received in lieu of fractional 
shares), and (c) the tax basis of the USB Common Stock received by a Zappco 
shareholder who exchanges Zappco Common Stock for USB Common Stock will be the 
same as the basis of the Zappco Common Stock surrendered in exchange therefor.  
EACH ZAPPCO SHAREHOLDER IS URGED TO CONSULT HIS, HER OR ITS OWN TAX ADVISER 
CONCERNING THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER OR ANY SUBSEQUENT 
SALES OF THE USB COMMON STOCK RECEIVED AS PART OF THE MERGER, AS WELL AS ANY 
APPLICABLE STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, BASED UPON SUCH 
SHAREHOLDER'S OWN PARTICULAR FACTS AND CIRCUMSTANCES.  SEE "THE MERGER--CERTAIN 
FEDERAL INCOME TAX CONSEQUENCES TO ZAPPCO SHAREHOLDERS."

RESALE OF USB COMMON STOCK

    The USB Common Stock issuable to holders of Zappco Common Stock upon 
consummation of the Merger has been registered under the Securities Act, and 
will be transferable freely and without restriction by those holders of Zappco 
Common Stock who receive such shares following consummation of the Merger and 
who are not deemed to be "affiliates" (as defined under the Securities Act). 
Zappco has agreed in the Merger Agreement to use its best efforts to obtain (i) 
signed representation letters (the "Affiliate Letter") (in the form attached as 
Exhibit A to the Merger Agreement) from each shareholder of Zappco who may 
reasonably be deemed an "affiliate" of Zappco (as such term is used in Rule 145 
under the Securities Act) to the effect that such person will not dispose of 
shares issued to him pursuant to the Merger except in compliance with Rule 145 
under the Securities Act, in a transaction that is otherwise exempt from the 
registration requirements under the Securities Act or in an offering registered 
under the Securities Act, and (ii) signed representation letters from all of 
the shareholders of Zappco (the "Representation Letter") (a copy of which is 
enclosed with this Proxy Statement/Prospectus) to the effect that it is each 
such person's plan and intent to hold (and not to sell, transfer or otherwise 
dispose of) at least 50% of the shares of USB Common Stock issued to him or her 
pursuant to the Merger.  See "The Merger--Resale of USB Common Stock Received 
by Zappco Shareholders."

    Until the second anniversary of the Effective Date, upon request, USB has 
agreed to purchase from the former shareholders of Zappco up to an aggregate of 
30% of the total number of shares of USB Common Stock issued upon exchange of 
Zappco Common Stock in the Merger.  The purchase price for each such share 
purchased by USB shall be equal to the closing price for a share of USB Common 
Stock as quoted on the NYSE on the trading day immediately prior to the day on 
which such purchase occurs.  At any such time as USB has purchased a number of 
shares of USB Common Stock representing 30% of the total number of shares 
issued pursuant to the Merger, USB's obligation to purchase shares shall cease. 

 In addition, USB may, in its sole and absolute discretion, suspend its 
obligation to purchase shares in the event of restrictions imposed by federal 
securities laws or accounting requirements for transactions accounted for as a 
pooling-of-interests.

ACCOUNTING TREATMENT

    USB intends to account for the Merger using the purchase method of
accounting under generally accepted accounting principles ("GAAP").  See "The
Merger--Accounting Treatment."

DISSENTERS' RIGHTS OF APPRAISAL

    Under Section 302A.471 of the MBCA,  any holder of Zappco Common Stock who 
does not vote in favor of the Merger and who strictly complies with the 
procedural requirements of Section 302A.473 of the MBCA, the full text of which 
is included in APPENDIX C to this Proxy Statement/Prospectus, will have the 
right to dissent to the Merger Agreement and make written demand for the 
payment of  "fair value" of such holder's shares of Zappco Common Stock. See 
"Rights of Dissenting Shareholders."

MARKET AND MARKET PRICES

   
    USB Common Stock is listed on the NYSE under the symbol "USB."  There is 
no public market for shares of Zappco Common Stock.  The following table sets 
forth the closing price per share of USB Common Stock and the "equivalent per 
share price" (as defined below) of Zappco Common Stock as of (i) September 
12, 1997, the last trading day before USB announced execution of the Merger 
Agreement, and (ii) November 6, 1997.  The "equivalent per share price" of 
the Zappco Common Stock as of each such date equals the Purchase Price, 
assuming no adjustments, divided by the average closing price per share of 
USB Common Stock for the ten consecutive trading days ending on such date, 
divided by the number of shares of Zappco Common Stock outstanding on such 
date, and multiplied by the closing price per share of USB Common Stock on 
such date. See "The Merger--Terms of the Merger; Consideration to be Received 
by Zappco Shareholders."

    Apart from the publicly disclosed information concerning USB which is 
included and incorporated by reference in this Proxy Statement/Prospectus, 
USB does not know what factors account for changes in the market price of its 
stock. NO ASSURANCE CAN BE GIVEN AS TO THE MARKET PRICES OF USB COMMON STOCK 
AT ANY TIME BEFORE THE EFFECTIVE DATE, OR AT ANY TIME THEREAFTER.  See "--The 
Proposed Merger" above and "The Merger--Terms of the Merger; Consideration to 
be Received by Zappco Shareholders." 

EXPENSES

    The Merger Agreement provides that all costs and expenses incurred in 
connection with such agreement and the transactions contemplated thereby shall 
be paid by the party incurring such costs and expenses, except for certain 
costs and expenses that USB has agreed to reimburse to Zappco.  See "The 
Merger--Expenses."

DIFFERENCES IN RIGHTS OF ZAPPCO SHAREHOLDERS

    Upon consummation of the Merger, holders of Zappco Common Stock will become 
holders of USB Common Stock.  As a result, their rights as shareholders, which 
are now governed by Minnesota corporate law and Zappco's Articles of 
Incorporation and Bylaws, will be governed by Delaware corporate law and USB's 
Certificate of Incorporation and Bylaws.  Because of certain differences 
between Minnesota and Delaware corporate law and between the provisions of 
Zappco's Articles of Incorporation and Bylaws and USB's Certificate of 
Incorporation and Bylaws, the current rights of Zappco shareholders will change 
significantly after the Merger.  For a discussion of the material differences 
between the rights of shareholders of Zappco and the rights of shareholders of 
USB, see "The Merger--Certain Differences in Rights of Zappco Shareholders."

EXCESS PARACHUTE PAYMENTS

    The Merger Agreement provides that Zappco or its successor, USB, shall make 
no payments that separately or in the aggregate could or would result in the 
payment of any "excess parachute payments" within the meaning of Section 280G 
of the Code, unless and until such payments are approved by Zappco's 
shareholders in accordance with the provisions of Sections 280G(b)(5)(A)(ii) 
and 280G(b)(5)(B) of the Code.  In order to avoid the denial of deductibility 
and the imposition of the excise tax which applies to 280G Payments, Zappco's 
shareholders are being asked to approve such payments.  Approval of the 280G 
Payments requires the affirmative vote of more than 75% of the voting power of
all outstanding shares of Zappco Common Stock, excluding those shares held or 
constructively owned by


                                       10
<PAGE>

the individuals (Messrs. Zapp and Leisen) whose compensation is being 
considered.  See "Excess Parachute Payments."

    As described in more detail elsewhere in this Proxy Statement/Prospectus, 
Mr. Zapp will receive an annual amount of $60,000 in salary continuation 
payments for 15 years following the Merger and annual payments of $200,000 from 
USB for eight years under the terms of his Noncompetition Agreement.  Mr. 
Leisen will receive an annual amount of $60,000 in salary continuation payments 
for 15 years following the Merger, annual payments of $200,000 for seven years 
under his Noncompetition Agreement, and compensation for continued employment 
with USB consisting of an annual base salary of $165,000 and certain contingent
incentive compensation.  See "The Merger--Noncompetition Agreements" for a 
description of the Noncompetition Agreements.

    Shareholder approval of the 280G Payments is a condition to Zappco
consummating the Merger.

                    NOTES TO COMPARATIVE UNAUDITED PER SHARE DATA

    (1)  The pro forma combined book values per share of USB Common Stock are
         based upon the pro forma total common equity for USB and Zappco,
         divided by the total pro forma shares of USB Common Stock assuming
         conversion of Zappco Common Stock at an exchange ratio of 50.3 shares
         of USB Common Stock for each share of Zappco Common Stock (the "Pro
         Forma Exchange Ratio").  The pro forma equivalent book values per
         share of Zappco Common Stock represent the pro forma combined amounts
         multiplied by the Pro Forma Exchange Ratio.  See "The Merger--Terms of
         the Merger; Consideration to be Received by Zappco Shareholders".

    (2)  The pro forma combined dividends declared assume no changes in the
         historical dividends declared per share of USB Common Stock.  The pro
         forma equivalent dividends per share of Zappco Common Stock represent
         the cash dividends declared on a share of USB Common Stock multiplied
         by the Pro Forma Exchange Ratio.  See "The Merger--Terms of the
         Merger; Consideration to be Received by Zappco Shareholders".

    (3)  The pro forma combined net income per share has been computed based on
         the average number of outstanding shares and common equivalent shares 
         of USB, and the average number of outstanding shares of Zappco 
         adjusted for the Pro Forma Exchange Ratio.  The pro forma equivalent 
         net income per share of Zappco Common Stock represents the pro forma 
         combined net income multiplied by the Pro Forma Exchange Ratio. See 
         "The Merger--Terms of the Merger; Consideration to be Received by 
         Zappco Shareholders".

                         PRO FORMA FINANCIAL INFORMATION

     Pro forma financial information is not presented as the requisitionof 
Zappco by USB, to be accounted for as a purchase, does not meet the requirements
of a significant business combination as defined by Reg. 210.1-02 and Reg. 
210.11-01 of the Commission.


                          SELECTED HISTORICAL FINANCIAL DATA

    The following tables set forth certain selected historical consolidated
financial information for USB and Zappco. The selected historical financial data
for the five years ended December 31, 1996 is derived from audited consolidated
financial statements of USB and Zappco.  The selected historical financial data
for the six months ended June 30, 1997 is derived from the unaudited historical
financial statements of USB and Zappco and reflect, in the respective opinions
of management of USB and Zappco, all adjustments (consisting only of normal
recurring adjustments) necessary for a fair presentation of such data.  On
August 1, 1997, USB (formerly First Bank System, Inc.) completed its acquisition
of U.S. Bancorp.  Accordingly, USB's consolidated financial statements and the
related supplemental financial data have been restated to give effect to the 
merger using the pooling-of-interests method of accounting, as filed as an 
exhibit to USB's Current Report on Form 8-K dated September 30, 1997, and
incorporated by reference herein.  This information should be read in
conjunction with the consolidated historical financial statements of USB and
Zappco, and the related notes thereto, incorporated by reference or included
elsewhere in this Proxy Statement/Prospectus.  See "Incorporation of Certain
Documents by Reference" and "Consolidated Financial Statements of Zappco, Inc."

                      INFORMATION CONCERNING THE SPECIAL MEETING

GENERAL

   

  This Proxy Statement/Prospectus is being furnished to holders of Zappco 
Common Stock as part of the solicitation of proxies by the Zappco Board of 
Directors for use at the Special Meeting to be held on December 11, 1997 and 
at any adjournment or postponement thereof.  This Proxy Statement/Prospectus, 
and the accompanying form of proxy, are being first mailed to Zappco 
shareholders on or about November 7, 1997.

    

  The principal purpose of the Special Meeting is to consider and vote upon
(i) the proposal to approve the Merger Agreement, dated September 12, 1997,
among USB and Zappco, which sets forth the terms and conditions of the Merger
and (ii) the proposal to approve the 280G Payments.  Upon consummation of the
Merger, each outstanding share of Zappco Common Stock will be converted into the
right to receive the Merger Consideration.  See "The Merger--Terms of the
Merger; Consideration to be Received by Zappco Shareholders."  The Merger is
subject to a number of conditions, including the receipt of required regulatory
and shareholder approvals.  See "The Merger--Conditions to Consummation of the
Merger."  

  In addition to approval of the Merger Agreement and the 280G Payments, the
shareholders of Zappco may be asked to approve a proposal to adjourn the Special
Meeting to permit further solicitation of proxies in the event there are not
sufficient votes at the time of the Special Meeting to approve the Merger
Agreement.  See "Adjournment of the Special Meeting."

   

EACH HOLDER OF ZAPPCO COMMON STOCK IS REQUESTED TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING PROXY AND REPRESENTATION LETTER AND RETURN BOTH PROMPTLY TO ZAPPCO
IN THE ENCLOSED, POSTAGE-PAID ENVELOPE OR BY FACSIMILE.  THE MERGER WILL BE
APPROVED IF IT RECEIVES THE AFFIRMATIVE VOTE OF A MAJORITY OF THE VOTES CAST AT
THE SPECIAL MEETING, AND THE 280G PAYMENTS PROPOSAL WILL BE APPROVED IF IT
RECEIVES THE AFFIRMATIVE VOTE OF THE HOLDERS OF MORE THAN 75% OF THE 
OUTSTANDING SHARES OF ZAPPCO COMMON STOCK EXCLUDING SHARES HELD OR 
CONSTRUCTIVELY OWNED BY EDWARD J. ZAPP AND JOHN E. LEISEN, PROVIDED A QUORUM IS
PRESENT OR REPRESENTED BY PROXY.

    

SOLICITATION, VOTING AND REVOCABILITY OF PROXIES

   

  The Board of Directors of Zappco has fixed the close of business on October 
31, 1997 as the Record Date for the determination of the shareholders of 
Zappco entitled to notice of and to vote at the Special Meeting.  
Accordingly, only holders of record of shares of Zappco Common Stock and 
participants in Zappco's Employee Stock Ownership Plan at the close of 
business on such date will be entitled to vote at the Special Meeting, with 
each share entitling its owner to one vote on all matters properly presented 
at the Special Meeting.  On the Record Date, there were 113 holders of 
record, including the Zappco Employee Stock Ownership Plan, of the 15,482 
shares of Zappco Common Stock then outstanding.  The presence, in person or 
by proxy, of at least a majority of the total number of outstanding shares of 
Zappco Common Stock entitled to vote at the Special Meeting is necessary to 
constitute a quorum at the Special Meeting.  Under Minnesota law, the 
affirmative vote of the holders of a majority of the voting power of all 
shares entitled to vote is required to approve the Merger Agreement. Approval 
of the 280G Payments requires the affirmative vote of 75% of the voting power 
of all outstanding shares of Zappco Common Stock, excluding those shares held 
or constructively owned by the individuals (Edward J. Zapp and John E. 
Leisen) whose compensation is being considered.  Approval of the adjournment 
of the Special Meeting requires the affirmative vote of at least a majority 
of the outstanding shares of Zappco Common Stock represented in person or by 
proxy at the Special Meeting, even if such number of shares is less than a 
quorum.  If an executed form of proxy is returned and the shareholder has 
affirmatively abstained from voting on any matter, the shares represented by 
such proxy will be considered present at the Special Meeting for purposes of 
determining a quorum and for purposes of calculating the vote, but will not 
be considered to have voted in favor as to such matter.

    

                                      17

<PAGE>

  It is expected that all of the 4,601 shares of Zappco Common Stock
beneficially owned by directors and executive officers of Zappco and their
affiliates at the Record Date (29.04% of the total number of outstanding shares
of Zappco Common Stock at such date) will be voted for approval of the Merger
Agreement, the 280G Payments (excluding shares held or constructively owned by
Messrs. Zapp and Leisen) and for adjournment of the Special Meeting under the
circumstances described herein.  As of the Record Date, USB beneficially owned
no shares of Zappco Common Stock and directors and executive officers of USB
beneficially owned no shares of Zappco Common Stock.

  If the accompanying form of proxy is properly executed and returned to
Zappco in time to be voted at the Special Meeting, the shares represented
thereby will be voted in accordance with the instructions marked thereon. 
EXECUTED BUT UNMARKED PROXIES WILL BE VOTED "FOR" APPROVAL OF THE MERGER
AGREEMENT, "FOR" APPROVAL OF THE 280G PAYMENTS AND "FOR" THE PROPOSAL TO ADJOURN
THE SPECIAL MEETING IF NECESSARY TO PERMIT FURTHER SOLICITATION OF PROXIES.  The
Board of Directors of Zappco does not know of any matters other than those
described in the notice of the Special Meeting that are to come before the
Special Meeting.  If any other matters are properly brought before the Special
Meeting, one or more of the persons named in the form of proxy will vote the
shares represented by such proxy upon such matters as determined in their best

  The cost of printing and mailing this Proxy Statement/Prospectus to Zappco
Shareholders will be borne by USB, and any additional cost of soliciting proxies
for the Special Meeting will be borne by Zappco.  In addition to use of the
mails, proxies may be solicited personally or by telephone, telegraph or
facsimile by directors, officers and employees of Zappco, who will not be
specially compensated for such activities.  Zappco will also request persons,
firms and companies holding shares in their names or in the name of their
nominees, which are beneficially owned by others, to send proxy materials to and
obtain proxies from such beneficial owners.  Zappco will reimburse such persons
for their reasonable expenses incurred in that connection.

  SHAREHOLDERS OF ZAPPCO ARE INSTRUCTED NOT TO SEND IN THE STOCK CERTIFICATES
REPRESENTING THEIR SHARES OF ZAPPCO COMMON STOCK WITH THEIR PROXY.  SHAREHOLDERS
OF ZAPPCO WILL RECEIVE INSTRUCTIONS REGARDING THE SURRENDER OF THEIR STOCK
CERTIFICATES IN A SEPARATE MAILING.  SEE "THE MERGER--SURRENDER OF ZAPPCO COMMON
STOCK CERTIFICATES."

                                      THE MERGER
                                   (PROPOSAL NO. 1)

  THIS SECTION OF THE PROXY STATEMENT/PROSPECTUS DESCRIBES CERTAIN ASPECTS OF
THE PROPOSED MERGER.  TO THE EXTENT THAT IT RELATES TO THE MERGER AGREEMENT, THE
FOLLOWING DESCRIPTION DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE MERGER AGREEMENT, A COPY OF WHICH IS ATTACHED
HERETO AS APPENDIX A AND IS INCORPORATED HEREIN BY REFERENCE.  ALL SHAREHOLDERS
ARE URGED TO READ THE MERGER AGREEMENT, THE EXHIBITS THERETO AND THE OTHER
APPENDICES HERETO IN THEIR ENTIRETY.

TERMS OF THE MERGER; CONSIDERATION TO BE RECEIVED BY ZAPPCO SHAREHOLDERS

  On the Effective Date, Zappco will merge with and into USB, with USB as the
surviving corporation.  The officers and directors of USB immediately prior to
the Effective Date will be the officers and directors of USB, as the surviving
corporation, after the Effective Date until their successors are duly elected or
appointed and qualified.  The Certificate of Incorporation and Bylaws of USB as
in effect immediately prior to the Merger will be the Certificate of
Incorporation and Bylaws of the surviving corporation until further amended as
provided therein and in accordance with law.  On the Effective Date, each issued
and outstanding share of Zappco Common Stock (other than shares to be canceled
as set forth below and Dissenting Shares) will be converted into the right to
receive a number of shares of USB Common Stock equal to $68 million (the
"Purchase Price," as may be adjusted as set forth below) divided by the average
of the closing prices of USB Common Stock as quoted on the NYSE for the ten
consecutive trading days ending with the day preceding the Effective Date
divided by the number of shares of Zappco Common Stock outstanding on the
Effective Date, with cash paid in lieu of fractional shares (the "Merger
Consideration").  Each share of Zappco Common Stock held directly or indirectly
by USB, other than shares of Zappco Common Stock held in a fiduciary capacity or
in satisfaction of a debt previously contracted, will be canceled, retired and
cease to exist when the Merger becomes effective, and no payment or exchange
will be made with respect to such shares.

  At least five business days prior to the Effective Date, Zappco will deliver
to USB a balance sheet of Zappco dated as of the last day of the month
immediately preceding the Effective Date (the "Final Balance Sheet").  The
Purchase Price will be (i) increased by the amount, if any, by which the Final
Retained Earnings (as defined below) exceeds $22,596,472 and (ii) decreased by
the amount, if any, by which the Final Retained Earnings is less than
$22,596,472.  Zappco reported Retained Earnings as of June 30, 1997 to be 
$23,818,963, which represents an increase from December 31, 1996 of $1,222,491.
USB and Zappco have agreed to cooperate and promptly commence good faith 
negotiations to resolve any disputes regarding the Final Balance Sheet.  The 
"Final Retained Earnings" shall be equal to the amount of Zappco's retained
earnings (referred to therein as "undivided profits") as reflected on the Final
Balance Sheet (which Final Balance Sheet will be as mutually agreed to by Zappco
and USB) plus an amount equal to the product of (i) the Average Daily Retained
Earnings (as defined below) times (ii) the number of days from, but excluding
the date of, the Final Balance Sheet to and including the Effective Date.  The
"Average Daily Retained Earnings" shall be equal to the quotient derived by
calculating the difference between retained earnings as reflected on the Final
Balance Sheet and $22,596,472 and dividing that difference (if positive) by the
number of calendar days in the period from but excluding December 31, 1996 to
and including the date of Final Balance Sheet.

  In determining the Final Retained Earnings and the Average Daily Retained
Earnings, Zappco will prepare the Final Balance Sheet in accordance with the
accounting methods and practices used by Zappco in preparing the financial
statements previously provided to USB, except that in no event will any gains on
sale of assets not in the ordinary course of business or other extraordinary or
unusual items be included in determining the Final Retained Earnings.  Without
limiting the generality of the foregoing, Zappco will continue to make provision
for loan losses and other reserves on the balance sheets of its Subsidiaries in
a manner consistent with past practices, and Zappco will not alter or vary its
practices and policies relating to classified loans and loan write-offs.  

                                      21

  The Merger Agreement provides that if, between September 12, 1997 (the date
of the Merger Agreement) and the Effective Date, shares of USB Common Stock are
changed into a different number or class of shares by reason of any
reclassification, recapitalization, split-up, combination, exchange of shares or
readjustment, or if a stock dividend thereon is declared with a record date
within such period, then the number of shares issued as a result of the Merger
will be appropriately and proportionately adjusted so that holders of Zappco
Common Stock will receive that number of shares of USB Common Stock that they
would have received if the record date for such reclassification,
recapitalization, split-up, combination, exchange of shares, readjustment or
stock dividend had been immediately following the Effective Date.

  No fractional shares of USB Common Stock will be issued in the Merger. 
Instead, the Merger Agreement provides that in lieu of any fractional share, USB
will pay to each holder of Zappco Common Stock who otherwise would be entitled
to receive a fractional share of USB Common Stock a cash amount (without
interest) determined by multiplying (i) the average closing price used in the
computation of Merger Consideration by (ii) the fractional share interest to
which such holder would otherwise be entitled.

  Shares of USB capital stock issued and outstanding immediately prior to the
Effective Date will remain issued and outstanding thereafter and will not be
affected by the Merger.

  The market price of USB Common Stock as of a recent date is set forth herein
under "Summary--Market and Market Prices."  NO ASSURANCE CAN BE GIVEN AS TO THE
MARKET PRICE OF USB COMMON STOCK  AT ANY TIME BEFORE THE EFFECTIVE DATE OR AS TO
THE MARKET PRICE OF USB COMMON STOCK AT ANY TIME THEREAFTER.
 
BACKGROUND OF AND REASONS FOR THE MERGER

  BACKGROUND OF THE MERGER.  In November 1996, USB (formerly First Bank
System, Inc.) provided an unsolicited written proposal to acquire Zappco.  The
Zappco Board of Directors discussed such proposal at its regular meeting on
November 14, 1996, at which meeting the Zappco Board of Directors adopted a
resolution affirming that Zappco was not for sale and preferred to remain
independent, although its Board of Directors would review substantive proposals
submitted by highly qualified buyers which offered the prospect of an
extraordinary premium price to Zappco shareholders.  The Zappco Board of
Directors at such meeting further appointed a Long Range Planning Committee to
further review the USB proposal.

  An exchange of correspondence, various meetings and discussions ensued. 
Representatives of USB and the Zappco Board of Directors Long Range Planning
Committee and their respective counsel met on May 21, 1997 to refine the terms
of a possible merger.  USB and Zappco executed a Confidentiality Agreement on
June 13, 1997 and representatives of USB commenced an off-site due diligence
review of Zappco.

  USB and Zappco executed a Letter Agreement and Summary Term Sheet, including
funding of an Option Deposit, on July 24, 1997.  Representatives of USB and
Zappco and their respective counsel thereafter negotiated the form of the
Agreement and Plan of Merger, and on September 11, 1997, the Zappco Board of
Directors met to consider the Merger Agreement.  Based on a variety of factors,
including receipt of a Fairness Opinion orally from Dain, the Zappco Board of
Directors approved the Merger Agreement at such meeting.  The Merger Agreement
was executed and delivered by the parties on September 12, 1997.  Following the
execution and delivery of the Merger Agreement, USB and Zappco formally
announced the execution of the Merger Agreement on September 15, 1997.

  REASONS OF ZAPPCO FOR THE MERGER.  The Board of Directors of Zappco, after
careful study and evaluation of economic, financial, legal and market factors,
believes that the Merger Agreement is in the best interests of Zappco and
Zappco's shareholders.  The Board believes that the Merger

                                      22

<PAGE>
   
Consideration is fair and that the receipt of the Merger Consideration 
represents an opportunity for the holders of Zappco Common Stock to exchange 
their shares of Zappco Common Stock for USB Common Stock as an equity 
security with a greater market liquidity.  Among the factors considered by 
the Board of Directors of Zappco in deciding to approve and recommend the 
execution of the Merger Agreement were the terms and conditions of the Merger 
Agreement; recent market prices for USB Common Stock; the lack of a public 
trading market for Zappco Common Stock; the nature of the banking business of 
Zappco and USB; the competitive position and outlook in a changing banking 
and financial services industry that is facing the development of interstate 
banking, a trend toward bank consolidation and increasing pressure to realize 
economies of scale; the various needs of Zappco shareholders; and the 
consideration to be received by the shareholders of Zappco in the Merger.  
While the Board of Directors did not give greater weight to any one of the 
factors listed above, the Board of Directors of Zappco considered the 
proposed exchange of Zappco Common Stock for USB Common Stock to be 
advantageous to its shareholders, both because the aggregate Purchase Price 
to be received per share of Zappco Common Stock has a value substantially in 
excess of the book value of such Zappco Common Stock and because the Zappco 
shareholders will receive securities which have a greater market liquidity 
than the Zappco Common Stock and which have historically paid dividends at a 
rate higher than the rate of dividends paid on the Zappco Common Stock which 
will be exchanged therefor in the Merger.

  RECOMMENDATION OF ZAPPCO BOARD OF DIRECTORS.  The Board of Directors of 
Zappco recommends that the shareholders of Zappco approve the Merger 
Agreement. The Zappco Board believes that the terms of the Merger Agreement 
are fair and that the Merger is in the best interests of Zappco and its 
shareholders.  In making its recommendation, the Zappco Board considered the 
opinion of Dain, financial advisor to the Zappco Board, dated September 12, 
1997 to the effect that the Merger Consideration is fair to the shareholders 
of Zappco from a financial point of view.  See "--The Fairness Opinion."  On 
November 6, 1997, the last sale price for USB Common Stock on the NYSE was 
$104.19 per share and the average closing price for the ten consecutive 
trading days ending on such date was $102.18 per share.  Based on such 
average closing price, and assuming no adjustment to the Purchase Price, the 
number of shares of USB Common Stock issued in exchange for each share of 
Zappco Common Stock would be 42.01.  The directors and executive officers of 
Zappco have unanimously indicated that they intend to vote the Zappco Common 
Stock that they hold in favor of the Merger Agreement.  See "Information 
Concerning the Special Meeting--Beneficial Ownership of Zappco Common 
Stock."

    

  THE BOARD OF DIRECTORS OF ZAPPCO RECOMMENDS THAT ZAPPCO SHAREHOLDERS 
VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

  REASONS OF USB FOR THE MERGER.  The acquisition of Zappco by USB will expand
USB's retail banking operations in Minnesota.  The acquisition will allow USB to
leverage its existing presence in Minnesota, providing the opportunity to
realize economies from consolidation.

THE FAIRNESS OPINION

  Dain has acted as financial advisor to Zappco in connection with the Merger. 
Dain was selected by Zappco based on a recommendation of Zappco legal counsel. 
Further, the Zappco Board expressly desired to obtain such a written opinion
from a nationally recognized investment banking firm with experience in the
valuation of financial institutions and securities and which had never been
previously engaged by Zappco.  Dain is a nationally recognized investment
banking firm and is regularly engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, leveraged buyouts,
negotiated underwritings, competitive biddings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate
and other purposes.

                                      23

<PAGE>

  In connection with Dain's engagement, Zappco requested that Dain evaluate
the fairness of the consideration to be received by the Zappco shareholders from
a financial point of view.  Dain rendered to the Zappco Board a written opinion
dated September 12, 1997 to the effect that, as of such date and based upon and
subject to certain matters stated in such opinion, the consideration was fair to
the holders of Zappco Common Stock from a financial point of view.  

  THE FULL TEXT OF DAIN'S WRITTEN OPINION TO THE ZAPPCO BOARD DATED SEPTEMBER
12, 1997, WHICH SETS FORTH THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, MATTERS
CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX B
TO THIS PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. 
SHAREHOLDERS OF ZAPPCO ARE URGED TO READ THIS OPINION CAREFULLY IN IT ENTIRETY. 
DAIN'S OPINION RELATED ONLY TO THE FAIRNESS OF THE CONSIDERATION FROM A
FINANCIAL POINT OF VIEW, DOES NOT ADDRESS ANY OTHER ASPECT OF THE PROPOSED
MERGER OR ANY RELATED TRANSACTION AND DOES NOT CONSTITUTE A RECOMMENDATION TO
ANY SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE AT THE ZAPPCO SPECIAL
MEETING.  THE SUMMARY OF THE OPINION OF DAIN SET FORTH IN THIS PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF SUCH OPINION.

  In arriving at its opinion, Dain reviewed the Merger Agreement and certain
publicly available business and financial information relating to Zappco and
USB.  Dain also reviewed certain other information relating to Zappco and USB,
including financial forecasts provided to Dain by Zappco, and met with the
management of Zappco to discuss the business and prospects of Zappco.  Dain also
discussed with the management of USB expected savings that might be realized as
a result of the Merger.  Dain also considered certain financial data of Zappco
and certain financial and stock market data of USB and compared that data with
similar data for other publicly held companies in businesses similar to those of
Zappco and USB and considered, to the extent publicly available, the financial
terms of certain other business combinations and other transactions recently
effected.  Dain also considered such other information, financial studies,
analyses and investigations and financial, economic and market criteria which
Dain deemed relevant.

  In connection with its review, Dain did not assume any responsibility for
independent verification of any of the information provided to or otherwise
reviewed by Dain and relied on such information being complete and accurate in
all material respects.  With respect to the financial forecasts, Dain assumed
that such forecasts were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the management of Zappco as to
the future financial performance of Zappco.  Dain was not requested to conduct,
and did not conduct, a review of individual credit files or make an independent
evaluation or appraisal of the assets or liabilities (contingent or otherwise)
of Zappco nor was Dain furnished with any such evaluations or appraisals,
including loan or lease portfolios or the allowances for losses with respect
thereto, and Dain assumed that such allowances of Zappco are in the aggregate
adequate to cover such losses.  Dain further assumed that in the course of
obtaining the necessary regulatory and third-party consents for the proposed
Merger and transactions contemplated thereby, no restriction will be imposed
that will have a material adverse effect on the contemplated benefits of the
Merger or the transactions contemplated thereby.   Dain's opinion was
necessarily based upon information available to Dain, and financial, economic,
market and other conditions as they existed and could be evaluated on the date
of its opinion.  Dain did not express any opinion as to the actual value of the
USB Common Stock when issued pursuant to the Merger or the prices at which the
USB Common Stock will trade subsequent to the Merger.  In connection with its
engagement, Dain was not requested to, and did not, solicit third-party
indications of interest in acquiring all or any part of Zappco.  Although Dain
evaluated the consideration from a financial point of view, Dain was not
requested to, and did not, recommend the specific consideration payable in the
Merger, which consideration was determined through negotiation between Zappco
and USB.  No other limitations were imposed by Zappco on Dain with respect to
the investigations made or procedures followed by Dain in rendering its opinion.

  In preparing its opinion to the Zappco Board, Dain performed a variety of
financial and comparative analyses, including those described below.  The
summary of Dain's analyses set forth

                                      24

<PAGE>

below does not purport to be a complete description of the analyses 
underlying Dain's opinion, but rather, sets forth a description of the 
material analyses performed by Dain for purposes of such opinion.  The 
preparation of a fairness opinion is a complex analytic process involving 
various determinations as to the most appropriate and relevant methods of 
financial analyses and the application of those methods to the particular 
circumstances and, therefore, such an opinion is not readily susceptible to 
summary description.  In arriving at its opinion, Dain made qualitative 
judgments as to the significance and relevance of each analysis and factor 
considered by it.  Accordingly, Dain believes that its analyses must be 
considered as a whole and that selecting portions of its analyses and 
factors, without considering all analyses and factors, could create a 
misleading or incomplete view of the processes underlying such analyses and 
its opinion.  In its analyses, Dain made numerous assumptions with respect to 
Zappco, USB, industry performance, regulatory, general business, economic, 
market and financial conditions and other matters, many of which are beyond 
the control of Zappco and USB.  No company, transaction or business used in 
such analyses as a comparison is identical to Zappco, USB or the proposed 
Merger, nor is an evaluation of the results of such analyses entirely 
mathematical; rather, such analyses involve complex considerations and 
judgments concerning financial and operating characteristics and other 
factors that could affect the acquisition, public trading or other values of 
the companies, business segments or transactions being analyzed.  The 
estimates contained in such analyses and the ranges of valuations resulting 
from any particular analysis are not necessarily indicative of actual values 
or predictive of future results or values, which may be significantly more or 
less favorable than those suggested by such analyses. In addition, analyses 
relating to the value of businesses or securities do not purport to be 
appraisals or to reflect the prices at which businesses or securities 
actually may be sold.  Accordingly, such analyses and estimates are 
inherently subject to substantial uncertainty.  Dain's opinion and financial 
analyses constituted only one of many factors considered by the Zappco Board 
in its evaluation of the proposed Merger and should not be viewed as 
determinative of the views of Zappco's Board or management with respect to 
the consideration or the proposed Merger.

  The following is a summary of each of the material financial analyses
performed by Dain in connection with its opinion dated September 12, 1997:

  CALCULATION OF IMPLIED VALUE OF CONSIDERATION.  Dain calculated the implied
value of the consideration based on the closing price of USB Common Stock on
September 9, 1997, which indicated an implied equity value for Zappco of
approximately $4,490 per share.    Dain also calculated the implied value of the
consideration based on the closing price of USB Common Stock on September 9,
1997 and assumed a 15% discount to reflect expected transferability restrictions
on 50% of USB Common Stock to be issued in the Merger.  Such process indicated
an implied equity value of $3,817 per share.  The implied equity value of $4,490
per share equated to implied multiples for Zappco of latest twelve months'
earnings per share ("EPS"), estimated calendar 1997 EPS, estimated calendar 1998
EPS,  and most recent book value and tangible book value of 20.4x, 17.8x, 16.7x,
2.34x and 2.39x, respectively.  The implied equity value of $3,817 per share
equated to implied multiples for Zappco of latest twelve months' EPS, estimated
calendar 1997 EPS, estimated calendar 1998 EPS and most recent book value and
tangible book value of 17.3x, 15.1x, 14.2x, 1.99x and 2.03x, respectively.  Dain
then compared these results with those derived from the analyses described
below.

  SELECTED TRANSACTIONS ANALYSIS.  Using publicly available information, Dain
analyzed the purchase prices and implied transaction multiples paid in 25
selected transactions in the banking industry that occurred between January 1,
1996 and September 5, 1997, where the sellers' assets were in the range of $100
million to $650 million, and where the sellers' headquarters was located in one
of the following states:  Minnesota, Illinois, Iowa, Kansas, North Dakota, South
Dakota, Wisconsin, or Nebraska (the "Selected Transactions").  All multiples
were based on information available at the time of the transaction.  This
analysis indicated median multiples for the Selected Transactions of latest 12
months' EPS, most recent book value and tangible book value and core deposit
premium of 14.8x, 1.83x, 1.87x, and 11.8%, respectively.  These multiples
compare to implied multiples for Zappco based on consideration equal to $4,490
per share of 20.4x, 2.34x, 2.39x, and 14.8%, respectively.  The

                                      25

Selected Transactions multiples compared to implied multiples for Zappco 
based on consideration received equal to $3,817 per share of 17.3x, 1.99x, 
2.03x and 11.0%, respectively.

  STAND ALONE VALUATION ANALYSIS.  Dain estimated the present value of Zappco
Common Stock on a stand-alone basis based upon a forecast provided by Zappco
management assuming that the Merger did not occur.  The value of the stock was
calculated by applying multiples ranging from 10.5x to 12.5x to earnings per
share for each year through 2001.  The projected stock values and dividends
expected to be paid by Zappco were then discounted to present values using
discount rates ranging from 12% to 18%.  This analysis indicated an implied
equity reference range for Zappco of approximately $2,095 to $3,041 per share.

  Dain also estimated the present value of Zappco Common Stock on a
stand-alone basis by applying multiples ranging from 0.9x to 1.3x to the
projected year-end book value each year through 2001.  The projected stock
values and dividends expected to be paid by Zappco were then discounted to
present values using discount rates ranging from 12% to 18%.  This analysis
indicated an implied equity reference range for Zappco of approximately $1,516
to $2,805 per share.

  DISCOUNTED DIVIDEND ANALYSIS.  Dain estimated the present value of the
future dividends that Zappco could pay on a stand-alone basis through fiscal
year 2001 based a forecast provided by Zappco management assuming that the
Merger did not occur.  The range of estimated terminal values was calculated by
applying multiples ranging from 0.9x to 1.3x to the projected 2001 year-end book
value of Zappco.  The dividends and estimated terminal values were then
discounted to present values using discount rates ranging from 12% to 18%.  This
analysis indicated an implied equity reference range for Zappco of approximately
$1,530 to $2,616 per share.

  SELECTED COMPANIES ANALYSIS.  Dain analyzed certain financial, operating and
stock market data of selected publicly traded companies in the banking industry
deemed to be similar to Zappco.  Such companies included:  BNCCORP;  Gold Banc
Corporation;  Mahaska Investment Company;  MNB Bancshares;  National City
Bancorp; and State Financial Services Corporation ("Selected Companies").  EPS
estimates for the Selected Companies were based on estimates of selected
investment banking firms as compiled by First Call.  All multiples were based on
closing stock prices of September 9, 1997.  This analysis indicated a median of
multiples for the Selected Companies for latest twelve months' EPS, estimated
calendar 1997 EPS, estimated calendar 1998 EPS and most recent book value and
tangible book values of 17.5x, 16.0x, 13.4x, 1.67x, and 1.84x, respectively. 
These multiples compare to implied multiples for Zappco based on consideration
received equal to $4,490 per share of 20.4x, 17.8x, 16.7x, 2.34x, and 2.39x
respectively.  The Selected Companies' multiples compare to implied multiples
for Zappco based on consideration received equal to $3,817 per share of 17.3x,
15.1x, 14.2x, 1.99x, and 2.03x, respectively.

  CONTRIBUTION ANALYSIS.  Dain analyzed the relative contributions of Zappco
and USB to, among other things, the estimated net income of the pro forma
combined company for the 1997 and 1998 fiscal years, before giving effect to
certain cost savings which the management of USB estimated could be achieved in
the Merger, with particular emphasis on the combined net income of Zappco and
USB before taking into account such cost savings.  This analysis indicated that,
without giving effect to such cost savings, Zappco would contribute
approximately 0.32% and 0.31% of the net income of the combined company in
fiscal 1997 and 1998, respectively.  Under the terms of the Merger, Zappco
shareholders would own approximately 0.32%, of the combined company upon
consummation of the Merger.

  PRO FORMA MERGER ANALYSIS.  Dain analyzed the potential pro forma effect of
the Merger on USB's EPS for calendar year 1998 relative to USB on a stand-alone
basis.  This analysis indicated that the Merger could be accretive to USB's EPS
in calendar year 1998, assuming certain cost savings anticipated by the
management of USB to result from the Merger are achieved.  The actual results
achieved by the combined company may vary from projected results and the
variations may be material.

  MISCELLANEOUS.  Pursuant to the terms of Dain's engagement, Zappco has 
agreed to pay Dain for its services in connection with providing the Fairness 
Opinion a fee of $100,000 which was payable upon delivery of the Fairness 
Opinion to the Zappco Board.  Zappco also has agreed to indemnify Dain and 
certain related persons and entities against certain liabilities, including 
liabilities under the federal securities laws, arising out of Dain's 
engagement. Dain has in the past provided financial services to USB unrelated 
to the proposed Merger, for which services Dain has received compensation.

  In the ordinary course of its business, Dain may actively trade the debt and
equity securities of USB for its own account and for the accounts of customers
and, accordingly, may at any time hold a long or short position in such
securities.

EFFECTIVE DATE OF THE MERGER

  The Merger will become effective upon the filing of an appropriate 
certificate of merger and articles of merger relating thereto with the 
Secretaries of State of the States of Delaware and Minnesota, respectively.  
The Merger Agreement provides that the parties thereto will cause the Merger 
to be effected as soon as practicable after receipt of all necessary 
regulatory approvals, provided that each of the conditions to consummation of 
the Merger has been satisfied or waived.  See "--Conditions to Consummation 
of the Merger." The Merger cannot become effective until Zappco shareholders 
have approved the Merger Agreement and all required regulatory approvals and 
actions have been obtained and taken.  See "--Regulatory Approvals Required." 
The Merger Agreement may be terminated by either USB or Zappco if the Merger 
has not become effective by February 28, 1998 (unless failure to consummate 
the Merger by such date shall be due to the action or failure to act of the 
party seeking to terminate the Merger Agreement in breach of such party's 
obligations thereunder).  See "--Termination."

SURRENDER OF ZAPPCO COMMON STOCK CERTIFICATES
   
  In a separate mailing, Zappco (or a representative of Zappco) will send a 
notice and transmittal form to each holder of Zappco Common Stock of record 
advising such holder of the procedure for surrendering his, her or its 
certificates evidencing Zappco Common Stock to Zappco.  Zappco or such 
representative will hold such shares in trust until the Effective Date.  Such 
notice and transmittal form will be sent as soon as practicable after the 
mailing of this Proxy Statement/Prospectus.  ZAPPCO SHAREHOLDERS SHOULD NOT 
SEND IN THEIR STOCK CERTIFICATES UNTIL THEY RECEIVE SUCH SEPARATE 
INSTRUCTIONS FROM ZAPPCO.

  Each holder of a certificate or certificates representing shares of Zappco 
Common Stock may surrender such certificate or certificates to Zappco, 
together with a properly completed and signed letter of transmittal, to 
effect the exchange of such certificate or certificates on his, her or its 
behalf.  Following shareholder approval of the Merger, and on or about the 
Effective Date, Zappco will present such certificates to USB and USB will 
distribute to the person in whose name such certificate is registered (or 
such other name as may be authorized by the holder) (1) a certificate or 
certificates representing the number of whole shares of USB Common Stock that 
such holder is entitled to receive in the Merger and (2) a cash payment in 
lieu of any fractional shares of USB Common Stock.

  THE SURRENDER OF CERTIFICATES TO ZAPPCO IS INTENDED TO EXPEDITE THE 
CERTIFICATE EXCHANGE PROCESS, AND IS SEPARATE AND APART FROM THE SOLICITATION 
OF PROXIES.  EVEN IF A SHAREHOLDER SUBMITS HIS, HER OR ITS CERTIFICATES TO 
ZAPPCO TO HOLD UNTIL THE EFFECTIVE DATE, SUCH SHAREHOLDER MAY CONTINUE TO 
REVOKE HIS OR HER PROXY AT ANY TIME PRIOR TO ITS EXERCISE.  NO PROXY WILL BE 
USED IF SUCH SHAREHOLDER ATTENDS AND VOTES AT THE SPECIAL MEETING IN PERSON.  
SEE "INFORMATION CONCERNING THE SPECIAL MEETING--SOLICITATION, VOTING AND 
REVOCABILITY OF PROXIES."  SHAREHOLDERS WHO HAVE SURRENDERED CERTIFICATES TO 
ZAPPCO IN ADVANCE OF THE SPECIAL MEETING MAY ALSO BE ELIGIBLE TO ASSERT HIS, 
HER OR ITS RIGHTS AS A DISSENTING SHAREHOLDER IF SUCH SHAREHOLDER SATISFIES 
THE PROCEDURAL REQUIREMENTS SPECIFIED IN THE MBCA.  SEE "RIGHTS OF DISSENTING 
SHAREHOLDERS."

    
                                      27

<PAGE>

  At and after the Effective Date and until surrendered and exchanged as
described above, certificates which, immediately prior to the Effective Date,
represented shares of Zappco Common Stock shall be deemed for all purposes to
represent and evidence only the right to receive the Merger Consideration to be
paid therefor.  After the Effective Date, the record holder of an outstanding
certificate formerly evidencing Zappco Common Stock will be entitled to vote the
shares of USB Common Stock into which such shares of Zappco Common Stock shall
have been converted on any matters on which the holders of record of USB Common
Stock, as of any date subsequent to the Effective Date, shall be entitled to
vote.  However, until such certificates are surrendered by Zappco to USB, no
dividend or distribution payable to holders of record of USB Common Stock will
be paid to the holders of record of such unsurrendered certificates.  Upon the
surrender of such a certificate, there will be paid to the holder thereof,
without interest, the amount of any dividends or distributions not previously
paid to such holder which had a record date on or after the Effective Date with
respect to such number of whole shares of USB Common Stock.  In any matters
relating to such certificates, USB may rely conclusively upon the record of
shareholders maintained by Zappco containing the names and addresses of the
holders of record of Zappco Common Stock at the Effective Date.

  If any certificate formerly evidencing Zappco Common Stock has been lost,
stolen or destroyed, Zappco  will, upon the making of an affidavit of that fact
by the holder thereof, issue a replacement certificate and present such
certificate to USB.  USB will pay in exchange for such lost, stolen or destroyed
certificate Merger Consideration as may be required pursuant to the Merger
Agreement; provided, however, that USB may, in its sole discretion and as a
condition to the issuance and payment of the Merger Consideration to which the
holder of such certificate is entitled as a result of the Merger, require the
owner thereof to deliver a bond in such sum as USB may direct as indemnity
against any claim that may be made against USB, Zappco or any other party with
respect to the certificate alleged to have been lost, stolen or destroyed. 
After the Effective Date, there shall be no further registration of transfers on
the records of USB of certificates formerly evidencing Zappco Common Stock, and
if a certificate is presented, it shall be canceled and exchanged for the Merger
Consideration as described above.  Certificates formerly evidencing shares of
Zappco Common Stock surrendered by any former shareholder of Zappco who is
deemed an "affiliate" of Zappco will not be exchanged for the Merger
Consideration until such shareholder has executed and delivered to USB an
Affiliate Letter (in the form attached as Exhibit A to the Merger Agreement)
with respect to the resale of shares of USB Common Stock received by such
shareholders in the Merger.  See "--Resale of USB Common Stock Received by
Zappco Shareholders."

  All Merger Consideration issued and paid upon the surrender of Zappco Common
Stock shall be deemed to have been paid in full satisfaction of all rights
pertaining to such shares of Zappco Common Stock.

CONDITIONS TO CONSUMMATION OF THE MERGER

  The Merger will occur only if the Merger Agreement is approved by the
requisite vote of Zappco shareholders.  In addition, consummation of the Merger
is subject to the satisfaction of certain other conditions, unless waived (to
the extent such waiver is permitted by law).  A failure of any such conditions
to be satisfied, if not waived, would prevent consummation of the Merger.

  The obligations of both USB and Zappco to consummate the Merger are subject
to satisfaction of the following conditions, among others:  (i) regulatory
approval for the consummation of the transactions contemplated by the Merger
Agreement shall have been obtained from the Federal Reserve Board and any other
governmental authority from whom approval is required, and all applicable
regulatory waiting periods shall have lapsed; (ii) no injunction or other court
order shall have been issued and remain in effect which would impair
consummation of the transactions contemplated by the Merger Agreement; (iii) no
law, statute, rule or regulation shall have been enacted or promulgated which
would materially impair consummation of the transactions contemplated by the
Merger Agreement; (iv) no action shall have been taken, nor any statute, rule,
regulation, judgment,

                                      28

<PAGE>

order or injunction shall have been proposed, enacted, enforced, promulgated, 
issued or deemed applicable to the transactions contemplated by the Merger 
Agreement by any court, government or governmental authority or agency, which 
would reasonably be expected to result in (a) restraining or prohibiting the 
consummation of the transactions contemplated by the Merger Agreement or 
obtaining material damages from Zappco, any of its Subsidiaries, USB or any 
of its subsidiaries, (b) prohibiting ownership or operation by USB of all or 
a material portion of the business or assets of Zappco, Zappco's Subsidiaries 
or USB or any of its subsidiaries, or compelling the disposal of or the 
holding separately of all or a material portion of the business or assets of 
USB, Zappco or their subsidiaries, or (c) requiring divestiture by USB of any 
of its, Zappco, or any Zappco Subsidiary's business or assets, (v) no party 
to the Merger Agreement shall have terminated such agreement as permitted 
therein and (vi) approval by Zappco shareholders of the 280G Payments.  The 
Merger Agreement provides that no regulatory approval referred to in (i) 
above shall contain any conditions or restrictions that USB reasonably 
believes will materially restrict or limit the business or activities of USB, 
Zappco or Zappco's Subsidiaries or have a material adverse effect on, or 
would be reasonably likely to have a material adverse effect on, the 
business, operations or financial condition of USB and its subsidiaries taken 
as a whole, on the one hand, or Zappco or Zappco's Subsidiaries, taken as a 
whole, on the other hand.

  In addition to the foregoing conditions, the obligation of Zappco to
consummate the Merger is subject to satisfaction of the following conditions,
among others:  (i) the representations and warranties of USB set forth in the
Merger Agreement shall be true and correct as of the date of such agreement and
as of the Effective Date, except where the failure to be true and correct would
not have, or would not reasonably be expected to have, a material adverse effect
on the business, operations or financial condition of USB and its subsidiaries,
taken as a whole; and USB shall in all material respects have performed each
obligation and agreement and complied with each covenant to be performed and
complied with by it under the Merger Agreement at or prior to the Effective
Date; (ii) Zappco shall have received an officer's certificate of the Chief
Financial Officer of USB to the effect that she has no reason to believe that
the conditions set forth in (i) above have not been fulfilled; (iii) Zappco
shall have received a certificate of the corporate Secretary or an assistant
corporate Secretary of USB as to the text of resolutions authorizing the
corporate actions necessary to approve the Merger Agreement and the transactions
contemplated thereby and as to the incumbency of certain officers of USB; (iv)
since the date of the Merger Agreement, there shall have been no material
adverse change in, and no event, occurrence or development in the business of
USB or its subsidiaries that, taken together with other events, occurrences and
development with respect to such business, would have or would reasonably be
expected to have a material adverse effect on, the business, operations or
financial condition of USB and its subsidiaries, taken as whole; (v) USB shall
not have merged, or announced an agreement to merge, into another corporation,
or sold all or substantially all of its assets, or had one person or group
acquire, or had one person or group announce its intent to acquire, directly or
indirectly, beneficial ownership of more than 50% of the outstanding USB Common
Stock; (vi) the Registration Statement shall have been declared effective, and
the shares of USB Common Stock to be issued pursuant to the Merger shall have
been listed on the NYSE subject to notice of issuance; and (vii) Zappco shall
have received an opinion of Fredrikson & Byron, P.A. to the effect that, on the
basis of the facts, representations and assumptions set forth in such opinion
which are consistent with the state of facts existing on the Effective Date, the
Merger will be treated for federal income tax purposes as a reorganization
within the meaning of Section 368(a) of the Code and that accordingly: (a) no
gain or loss will be recognized for federal income tax purposes by USB or Zappco
as a result of the consummation of the Merger; (b) no gain or loss will be
recognized for federal income tax purposes by shareholders of Zappco who
exchange their Zappco Common Stock solely for USB Common Stock pursuant to the
Merger (except to the extent of any cash received in lieu of fractional shares);
and (c) the tax basis of the USB Common Stock received by shareholders of Zappco
who exchange all of their Zappco Common Stock solely for USB Common Stock in the
Merger will be the same as the tax basis of the Zappco Common Stock surrendered
in exchange therefor.

                                      29

<PAGE>

  In addition to the foregoing conditions, the obligation of USB to 
consummate the Merger is subject to satisfaction of the following conditions, 
among others: (i) the representations and warranties of Zappco in the Merger 
Agreement shall have been true and correct as of the date of such agreement 
and as of the Effective Date, except (a) where the failure to be true and 
correct would not have, or would not reasonably be expected to have, a 
material adverse effect on the business, operations or financial condition of 
Zappco and its Subsidiaries, taken as a whole, (b) for certain 
representations and warranties regarding loans, which shall be true and 
correct in all materials respects as of the date of the Merger Agreement, and 
certain lists regarding loans, which shall be true and correct in all 
material respects as of the respective dates of each such list, and (c) for 
certain representations and warranties regarding employees, which may be 
updated for facts arising after the date of the Merger Agreement and which 
shall be true and correct as of the date of such update; and Zappco shall in 
all material respects have performed each obligation and agreement and 
complied with each covenant to be performed and complied with by it under the 
Merger Agreement at or prior to the Effective Date; (ii) USB shall have 
received an officer's certificate of the Chief Executive Officer and the 
Chief Financial Officer of Zappco to the effect that they have no reason to 
believe that the conditions set forth in (i) above have not been fulfilled; 
(iii) USB shall have received a certificate of the corporate Secretary or an 
Assistant Secretary of Zappco as to resolutions authorizing the corporate 
actions necessary to approve the Merger Agreement and transactions 
contemplated thereby and as to the incumbency of certain officers of Zappco; 
(iv) since the date of the Merger Agreement, there shall have been no 
material adverse change in, and no event, occurrence or development in the 
business of Zappco or its Subsidiaries that, taken together with other 
events, occurrences and developments with respect to such business, would 
have or would reasonably be expected to have a material adverse effect on, 
the business, operations or financial condition of Zappco and its 
Subsidiaries, taken as a whole; provided, however, that a material adverse 
change or a material adverse effect shall not be deemed to include the impact 
of (a) changes in banking and similar laws of general applicability or 
interpretations thereof by courts or governmental authorities and (b) changes 
in GAAP or regulatory accounting requirements applicable to banks and their 
holding companies generally; (v) on the Effective Date all issued and 
outstanding shares of Zappco Common Stock shall be free and clear of any 
lien, pledge, security interest, encumbrance or charge of any kind; (vi) 
Zappco shall have delivered to USB the Affiliate Letters and Representation 
Letters acquired after Zappco has used its best efforts to acquire the same 
as described under "--Resale of USB Common Stock Received by Zappco 
Shareholders;" (vii) Zappco shall have delivered to USB the Final Balance 
Sheet described under "--Terms of Merger; Consideration to be Received by 
Zappco Shareholders," and (viii) USB shall have received an opinion of 
Dorsey & Whitney LLP to USB to the effect that, on the basis of the facts, 
representations and assumptions set forth in such opinion which are 
consistent with the state of facts existing on the Effective Date, the Merger
will be treated for federal income tax purposes as a reorganization within 
the meaning of Section 368(a) of the Code and that accordingly: (a) no gain 
or loss will be recognized for federal income tax purposes by USB or Zappco 
as a result of the consummation of the Merger; (b) no gain or loss will be 
recognized for federal income tax purposes by shareholders of Zappco who 
exchange their Zappco Common Stock solely for USB Common Stock pursuant to 
the Merger (except to the extent of any cash received in lieu of fractional 
shares); and (c) the tax basis of the USB Common Stock received by shareholders
of Zappco who exchange all of their Zappco Common Stock solely for USB Common 
Stock in the Merger will be the same as the tax basis of the Zappco Common Stock
surrendered in exchange therefor.

REGULATORY APPROVALS REQUIRED

  Under the Merger Agreement, the obligations of both USB and Zappco to
consummate the Merger are conditioned upon the receipt of all required
regulatory approvals (without certain restrictions or limitations) and the lapse
of all required regulatory waiting periods.  See "--Conditions to  Consummation
of the Merger."  There can be no assurance that any applicable regulatory
authority will approve or take other required action with respect to the Merger
or as to the date of such regulatory approval or other action.  USB and Zappco
are not aware of any governmental approvals or actions that are required in
order to consummate the Merger except as described below.  Should such other


                                      30
<PAGE>

approval or action be required, it is contemplated that USB and Zappco would
seek such approval or action.  There can be no assurance as to whether or when
any such other approval or action, if required, could be obtained. 

  FEDERAL RESERVE BOARD.  The Merger is subject to the prior approval of the 
Federal Reserve Board under Sections 3(a)(5) and 4(c)(8) of the Bank Holding 
Company Act.  Under the Bank Holding Company Act, the Federal Reserve Board 
is required, in approving a transaction such as the Merger, to take into 
consideration the financial and managerial resources and future prospects of 
the existing and proposed institutions and the convenience and needs of the 
communities to be served.  The Bank Holding Company Act prohibits the Federal 
Reserve Board from approving the Merger if it would result in a monopoly or 
be in furtherance of any combination or conspiracy to monopolize or to 
attempt to monopolize the business of banking in any part of the United 
States.  The Bank Holding Company Act also prohibits the Federal Reserve 
Board from approving the Merger if its effect in any section of the United 
States may be substantially to lessen competition or tend to create a 
monopoly, or if it would in any other manner result in a restraint of trade, 
unless the Federal Reserve Board finds that the anti-competitive effects of 
the Merger are clearly outweighed in the public interest by the probable 
effect of the transaction in meeting the convenience and needs of the 
communities to be served.  In addition, under the Community Reinvestment Act 
of 1977, as amended, the Federal Reserve Board must take into account the 
record of performance of the existing institutions in meeting the credit 
needs of the entire community, including low- and moderate-income 
neighborhoods, served by such institutions. 

  COMMISSIONER OF COMMERCE.  The acquisition of control of Melrose State by
USB as a result of the Merger is subject to the prior approval of the
Commissioner under the Minnesota Change in Control Statute.  Under the Minnesota
Change in Control Statute, the Commissioner may disapprove an acquisition if (i)
the proposed acquisition of control would result in a monopoly or would be in 
furtherance of any combination or conspiracy to monopolize or to attempt to
monopolize the business of banking in any part of the United States, (ii) the
effect of the proposed acquisition of control in any section of the United
States may be substantially to lessen competition or to create a monopoly or the
proposed acquisition of control would in any other manner be in restraint of
trade, and the anticompetitive effects of the proposed acquisition are not
clearly outweighed in the public interest by the probable effect of the
transaction in meeting the convenience and needs of the community to be served,
(iii) the financial condition of any acquiring person is such as might
jeopardize the financial stability of the bank or prejudice the interests of
depositors of the bank, (iv) the competence, experience, or integrity of any
acquiring person or of any of the proposed management personnel indicates that
it would not be in the public interest of the depositors of the bank or in the
interest of the public to permit such person to control the bank, (v) any
acquiring person neglects, fails, or refuses to furnish all of the information
required by the Commissioner, or (vi) the Commissioner determines that the
acquisition of control would result in an adverse effect on the Bank Insurance
Fund or the Savings Association Insurance Fund.

   
  CURRENT STATUS OF REGULATORY APPROVALS.  USB filed its notice of its intent 
to acquire Zappco with the Federal Reserve Board on October 1, 1997, and 
received approval of the transaction on November 3, 1997.  USB also filed its 
notice of its intent to acquire Melrose State as a result of the Merger with 
the Commissioner on October 1, 1997, approval of which is still pending as of 
the date of this Proxy Statement/Prospectus.
    

WAIVER AND AMENDMENT

  At any time prior to the Effective Date, any party to the Merger Agreement
may (i) extend the time for performance of any obligations or other acts of any
other party under the Merger Agreement or (ii) waive compliance with any of the
agreements of the other parties or with any conditions of its own obligations
contained in the Merger Agreement, to the extent that such obligations,
agreements and conditions are intended for such party's own benefit.

                                      31


<PAGE>

  The Merger Agreement may not be amended except by written instrument
approved by the parties to such agreement and signed on behalf of each of the
parties thereto.

TERMINATION

  The Merger Agreement may be terminated at any time prior to the Effective 
Date (i) by mutual consent of USB and Zappco; (ii) by either USB or Zappco, 
if any of the conditions to such party's obligation to consummate the 
transaction contemplated in the Merger Agreement have become impossible to 
satisfy; or (iii) by either USB or Zappco, if the Effective Date is not on or 
before February 28, 1998 (unless the failure to consummate the Merger by such 
date shall be due to the action or failure to act of the party seeking to 
terminate the Merger Agreement in breach of such party's obligations 
thereunder).  Any party desiring to terminate the Merger Agreement is 
required to give written notice of such termination and the reasons therefor 
to the other party.  If the Merger Agreement is terminated pursuant to the 
foregoing provisions, such termination will be without liability or 
obligation of any party (or any shareholder, officer, employee, agent, 
consultant or representative of such party) to any other party except (i) as 
may be otherwise provided in law or equity, (ii) for the obligations of the 
parties with respect to the USB Deposit (as defined under "USB Escrow 
Deposit" below) and (iii) for the survival of certain covenants relating to 
payment of expenses, confidentiality of information and non-disclosure.

LIMITATION ON NEGOTIATIONS

  The Merger Agreement provides that Zappco will not, and will cause its
Subsidiaries and Zappco's and each Subsidiary's officers, directors, employees,
agents and affiliates, not to, directly or indirectly, solicit, authorize,
initiate or encourage submission of, any proposal, offer, tender offer or
exchange offer from any person or entity (including any officers or employees of
Zappco or its Subsidiaries) relating to any liquidation, dissolution,
recapitalization, merger, consolidation or acquisition or purchase of all or a
material portion of the assets or deposits of, or any equity interest in, Zappco
or any Subsidiary, or other similar transaction or business combination
involving Zappco or any Subsidiary, or participate in any negotiations in
connection with or in furtherance of any of the foregoing or permit any person
other than USB and its representatives to have any access to the facilities of,
or furnish to any person other than USB and its representatives any non-public
information with respect to, Zappco or any Subsidiary in connection with or in
furtherance of any of the foregoing.  The Merger Agreement also requires Zappco
promptly to notify USB if any such proposal or offer, or any inquiry from or
contact with any person with respect thereto, is made concerning any such
transactions and promptly to provide USB with such information concerning such
matters as USB may request.  The foregoing provisions of the Merger Agreement
may have the effect of discouraging competing offers to acquire or merge with
Zappco.

  The Merger Agreement also provides that USB will not, and will cause its
subsidiaries and USB's and its subsidiaries' respective officers, directors,
employees, agents and affiliates not to, directly or indirectly negotiate with
any person or entity (including any of its or their officers or employees)
relating to any liquidation, dissolution, recapitalization, merger,
consolidation or acquisition or purchase of all or a material portion of the
assets or deposits of, or any equity interest in, any bank with its principal
offices located in, or within a 50-mile radius of, St. Cloud, Minnesota.

CONDUCT OF ZAPPCO BUSINESS PENDING THE MERGER

  The Merger Agreement provides that from the date of the Merger Agreement to 
the Effective Date, unless USB shall otherwise agree in writing or as 
otherwise contemplated or permitted by the Merger Agreement, the business of 
Zappco and its Subsidiaries will be conducted only in the ordinary course, on 
an arms-length basis and in accordance in all material respects with past 
practices and all applicable laws, rules and regulations.  In addition, the 
Merger Agreement specifically provides that

                                      32

during such period, except as otherwise permitted by the Merger Agreement or

     (a) neither Zappco nor any Subsidiary shall, directly or indirectly, (i)
         amend or propose to amend its articles or bylaws; (ii) issue or sell
         any of its equity securities, securities convertible into or
         exchangeable for its equity securities, warrants, options or other
         rights to acquire its equity securities, or any bonds or other
         securities, except (A) deposit and other bank obligations in the
         ordinary course of business and (B) pursuant to the exercise of the
         options, warrants, conversion privileges and other rights set forth on
         a schedule to the Merger Agreement; (iii) redeem, purchase, acquire or

         of Zappco or any Subsidiary, or declare, set aside or pay any dividend
         or other distribution payable in cash, property or otherwise with
         respect to shares of capital stock of Zappco, except that the Banks
         shall be permitted to pay dividends on the shares of common stock of
         the Banks owned by Zappco; (v) borrow any amount or incur or become
         subject to any material liability, except liabilities incurred in the
         ordinary course of business, but in no event will Zappco or any Bank
         enter into any long-term borrowings with a term of greater than one
         year; (vi) discharge or satisfy any material lien or encumbrance on
         the properties or assets of Zappco or any Subsidiary or pay any
         material liability, except otherwise in the ordinary course of
         business; (vii) sell, assign, transfer, mortgage, pledge or subject to
         any lien or other encumbrance any of its assets, except (A) in the
         ordinary course of business; provided, that any such sale, assignment
         or transfer of any real property shall not be considered in the
         ordinary course of business, (B) liens and encumbrances for current
         property taxes not yet due and payable, (C) liens and encumbrances
         which do not materially affect the value of, or interfere with the
         past or future use or ability to convey, the property subject thereto
         or affected thereby; (viii) cancel any material debt or claims or
         waive any rights of material value, except in the ordinary course of
         business; (ix) acquire (by merger, exchange, consolidation,
         acquisition of stock or assets or otherwise) any corporation,
         partnership, joint venture or other business organization or division
         or material assets thereof, or assets or deposits that are material to
         Zappco, except in exchange for debt previously contracted, including
         OREO; (x) other than as set forth on a schedule to the Merger
         Agreement, make any single or group of related capital expenditures or
         commitments therefor in excess of $25,000 or enter into any lease or
         group of related leases with the same party which involves aggregate
         lease payments payable of more than $50,000 for any individual lease
         or involves more than $100,000 for any group of related leases in the
         aggregate; or (xi) enter into or propose to enter into, or modify or
         propose to modify, any agreement, arrangement or understanding with
         respect to any of the matters set forth above;
    

     (b) neither Zappco nor any Subsidiary shall, directly or indirectly, enter
         into or modify any employment, severance or similar agreements or
         arrangements with, or grant any bonuses, wage, salary or compensation
         increases, or severance or termination pay to, or promote, any
         director, officer, employee, group of employees or consultant or hire
         any employee, except in the ordinary course of business consistent
         with past practice;

     (c) neither Zappco nor any Subsidiary shall adopt or amend any bonus,
         profit sharing, stock option, pension, retirement, deferred
         compensation, or other employee benefit plan, trust, fund, contract or
         arrangement for the benefit or welfare of any employees, except as and
         to the extent required by law or as disclosed on a schedule to the
         Merger Agreement;

     (d) each of Zappco and its Subsidiaries shall use commercially reasonable
         efforts to cause its current insurance policies not to be canceled or
         terminated or any of the coverage thereunder to lapse, unless
         simultaneously with such termination, cancellation or lapse,

                                      33


<PAGE>



         replacement policies providing coverage substantially equal to the
         coverage under the canceled, terminated or lapsed policies are in full
         force and effect; 

     (e) neither Zappco nor any Subsidiary shall enter into any settlement or
         similar agreement with respect to, or take any other significant
         action with respect to the conduct of, any action, suit, proceeding,
         order or investigation which is set forth on a schedule to the Merger
         Agreement or to which Zappco or any Subsidiary becomes a party after
         the date of the Merger Agreement, without prior consultation with USB;

     (f) each of Zappco and its Subsidiaries shall use commercially reasonable
         efforts to preserve intact in all material respects the business
         organization and the goodwill of each of Zappco and its Subsidiaries
         and to keep available the services of its officers and employees as a
         group and preserve intact material agreements and credit facilities,
         and Zappco shall confer on a regular and frequent basis with
         representatives of USB, as reasonably requested by USB, to report on
         operational matters and the general status of ongoing operations;

     (g) neither Zappco nor any Subsidiary shall take any action with respect
         to investment securities held or controlled by any of them
         inconsistent with past practices, alter its investment portfolio
         duration policy as heretofore in effect or, without prior consultation
         with USB, take any action that would have or could reasonably be
         expected to have a material effect on the Banks' asset/liability
         position;

     (h) the Banks shall not make any agreements or commitments binding them to
         extend credit except in a manner consistent with past practice and in
         accordance with each Bank's lending policies as disclosed to USB, and
         shall not make any agreements or commitments binding it to extend
         credit in an amount in excess of $500,000, or sell, assign or
         otherwise transfer any participation in any loan, in each case without
         prior or prompt subsequent notification to USB; 

     (i) with respect to properties leased by Zappco or any Subsidiary, neither
         Zappco nor any Subsidiary shall renew, exercise an option to extend,
         cancel or surrender any lease of real property nor allow any such
         lease to lapse, without the consent of USB, which consent shall not be
         unreasonably withheld; 

     (j) neither Zappco nor any Subsidiary shall make any change in its
         accounting methods or practices, other than changes required by law or
         regulation made in accordance with GAAP or regulatory accounting
         principles generally applicable to depository institutions such as the
         Banks, as the case may be; 

     (k) neither Zappco nor any Subsidiary shall renew for any period in excess
         of one month its agreement with Deluxe Corporation (or its
         affiliates); and

     (l) neither Zappco nor any Subsidiary shall agree to do any of the
         foregoing.

  The Merger Agreement also prevents Zappco from negotiating for an
acquisition of Zappco by any other party, subject to specified exceptions, see
"--Limitations on Negotiations," and from taking any action which would
disqualify the Merger as a "reorganization" that would be tax-free to
shareholders of Zappco pursuant to Section 368(a) of the Code, see "--Certain
Federal Income Tax Consequences to Zappco Shareholders."  Zappco has also agreed
not to sell any loan participation or renew any loan participation without first
offering to sell such loan participation to USB on the same terms.

                                      34

<PAGE>

  In addition, the Merger Agreement provides that at the request of USB, on
the business day before the Merger takes effect, the Banks will establish,
consistent with GAAP, such additional accruals and reserves as may be necessary
to conform the Banks' accounting and credit loss reserve practices and methods
to those of USB and to reflect the plans of USB with respect to the conduct  of
the business of the Banks following the Merger and to provide for the costs and
expenses related to the consummation by the Banks of the transactions
contemplated by the Merger Agreement.  The establishment of such accruals and
reserves will not be an adjustment to the Final Balance Sheet or the Final
Retained Earnings described in "--Terms of the Merger; Consideration to be
Received by Zappco Shareholders," and will not constitute a breach of any
representation or warranty of Zappco contained in the Merger Agreement or
constitute a material adverse change in the business, operations or financial
condition of Zappco and its Banks, taken as a whole.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

  SALARY CONTINUATION AGREEMENTS.  Zappco is party to salary continuation
agreements with Edward J. Zapp, its Chairman of the Board, President and a
shareholder, and with John E. Leisen, its Vice President, a director and a
shareholder.  USB has agreed to assume and be bound by the terms of such salary
continuation agreements.  As a result of the Merger and the anticipated
continuation of such agreements, USB and Zappco expect that Messrs. Zapp and
Leisen will each receive an annual amount of $60,000 for 15 years in salary
continuation payments following the Merger.

   
  NONCOMPETITION AGREEMENTS.  Simultaneously with the execution of the Merger 
Agreement, each of Messrs. Zapp and Leisen entered into a Noncompetition 
Agreement with USB, pursuant to which each of Messrs. Zapp and Leisen will 
receive separate consideration to be paid by USB in an annual amount of 
$200,000 for approximately eight and seven years, respectively, subject to 
adjustment, as well as certain retiree medical benefits.  See 
"--Noncompetition Agreements."

  OFFER OF CONTINUED EMPLOYMENT.  Mr. Leisen and certain other employees of
Zappco have been offered continued employment with USB following the anticipated
closing of the Merger.  Mr. Leisen has been offered continued employment through
December 31, 1998, or longer as mutually agreed upon, during which time Mr.
Leisen will receive an annual base salary of $165,000, as well as benefits
normally offered to eligible employees of USB.  Mr. Leisen will also be granted
4,000 shares of USB restricted stock, which will vest over a three-year period.
    

  SEVERANCE PAYMENTS.  Pursuant to the Merger Agreement, eight employees
mutually agreed upon by USB and Zappco will enter into severance agreements with
USB substantially in the form provided by USB to Zappco.  With respect to
employees of Zappco or any of its Subsidiaries not subject to any other
severance agreement, the Merger Agreement provides that USB will pay severance
to such employees in accordance with USB's General Severance Pay Program, as the
same may be amended from time to time.  Nothing in the Merger Agreement,
however, whether express or implied, confers upon any employee of Zappco, any
Subsidiary or USB or any other person any rights or remedies, including but not
limited to (i) any right to employment or recall, (ii) any right to continued
employment for any specified period or (iii) any right to claim any particular
compensation, benefit or aggregate of benefits, of any kind or nature.  The
severance payments described above may be paid to officers of Zappco and its
Subsidiaries who are also shareholders of Zappco.

   
  PURCHASE OF CERTAIN ASSETS.  Pursuant to the Merger Agreement, Mr. Zapp has
agreed to purchase from Zappco, immediately prior to the Effective Date, certain
assets of a personal and historical interest to the founding families (listed on
a schedule to the Merger Agreement) at the book value of such assets as of the
last day of the month preceding the month in which the Effective Date occurs.
    

                                      35

<PAGE>

  The foregoing interests of members of management or shareholders of Zappco
in the Merger may mean that such persons have personal interests in the Merger
which may not be identical to the interests of nonaffiliated shareholders.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES TO ZAPPCO SHAREHOLDERS

  Zappco expects that the Merger will be treated as a tax-free reorganization
within the meaning of Section 368(a)(1)(A) of the Code and that for federal
income tax purposes no gain or loss will be recognized by any shareholder of
Zappco upon the receipt of USB Common Stock for Zappco Common Stock pursuant to
the Merger.  Gain will be recognized as described below upon the receipt of cash
in lieu of fractional shares of USB Common Stock.  The Internal Revenue Service
(the "Service") has not been and will not be asked to rule upon the tax
consequences of the Merger.  Instead, Zappco will rely upon the opinion of
Fredrikson & Byron, P.A., its special outside legal counsel, as to certain
federal income tax consequences of the Merger. The opinion of Fredrikson &
Byron, P.A. will be based upon facts described herein, upon certain
representations made by Zappco and USB in the Merger Agreement, certain
representations made by management of Zappco and USB, certain representations
made by Zappco shareholders, and certain assumptions regarding the Merger and
the parties thereto.  The opinion of Fredrikson & Byron, P.A. will also be based
upon the Code, regulations now in effect thereunder, current administrative
rulings and practice, and judicial authority, all of which are subject to
change.  An opinion of counsel is not binding on the Service and there can be no
assurance, and none is hereby given, that the Service will not take a position
contrary to one or more positions reflected herein or that the opinion will be
upheld by the courts if challenged by the Service.  EACH HOLDER OF ZAPPCO COMMON
STOCK IS URGED TO CONSULT HIS, HER OR ITS OWN TAX AND FINANCIAL ADVISERS AS TO
THE EFFECT OF SUCH FEDERAL INCOME TAX CONSEQUENCES ON HIS, HER OR ITS OWN
PARTICULAR FACTS AND CIRCUMSTANCES AND ALSO AS TO ANY STATE, LOCAL, FOREIGN OR
OTHER TAX CONSEQUENCES ARISING OUT OF THE MERGER OR FROM SUBSEQUENT SALES OF USB
COMMON STOCK, WHETHER OR NOT PURSUANT TO USB'S AGREEMENT TO REPURCHASE UP TO 30
PERCENT OF THE SHARES OF USB COMMON STOCK RECEIVED PURSUANT TO THE MERGER DURING
THE FIRST TWO YEARS FOLLOWING THE EFFECTIVE DATE.  SEE "--RESALE OF USB COMMON
STOCK RECEIVED BY ZAPPCO SHAREHOLDERS."

  Based upon various representations and assumptions and subject to various 
qualifications, Fredrikson & Byron, P.A. will opine that the Merger will 
qualify as a "reorganization" under Section 368(a) of the Code and, 
accordingly, the following federal income tax consequences will result from 
the Merger:

     (a) No gain or loss will be recognized for federal income tax purposes by
  USB or Zappco as a result of the consummation of the Merger;

     (b) No gain or loss will be recognized by any Zappco shareholder (except in
  connection with the receipt of cash in lieu of fractional shares) upon the
  receipt of USB Common Stock for Zappco Common Stock in the Merger; and

     (c) The tax basis of the USB Common Stock received by a Zappco shareholder
  who exchanges Zappco Common Stock for USB Common Stock will be the same as the
  basis of the Zappco Common Stock surrendered in exchange therefor.

  The opinions described above will be based upon certain assumptions,
including the assumption that the shareholders of Zappco do not have any plan or
intention to dispose, sell, exchange or otherwise dispose of a number of shares
of USB Common Stock received pursuant to the Merger that would reduce the
ownership of USB Common Stock by such shareholders to a number of shares having
a value, as of the date of the Merger, which is less than 50 percent of the
value of all of the formerly outstanding Zappco Common Stock held by such Zappco
shareholders as of the same date.  EACH ZAPPCO SHAREHOLDER IS ASKED TO SIGN THE
ENCLOSED REPRESENTATION LETTER WHICH CONTAINS A REPRESENTATION REGARDING SUCH
INTENT.  EACH ZAPPCO SHAREHOLDER IS ASKED TO RETURN SUCH REPRESENTATION LETTER
WITH HIS, HER OR ITS PROXY.

                                      36

<PAGE>


  Dissenters, if any, will receive solely cash for their Zappco Common Stock
as described in "Rights of Dissenting Shareholders" below.  The cash received 
will either be subject to treatment as a dividend, or will be subject to capital
gain treatment as proceeds of the sale of the dissenting shareholder stock, 
depending upon whether the transaction as to such shareholder would qualify as 
a redemption under Code Section 302.  If redemption treatment is not available, 
the payment will be treated as a dividend.

   
  Generally, any shareholder who dissents and has his, her or its shares 
purchased will be able to qualify for redemption capital gain treatment 
unless he, she or it is also deemed to own shares of another person under 
Code Section 318.  In that case, redemption capital gain treatment would be 
available nonetheless if (i) the distribution is found to be not essentially 
equivalent to a dividend under the subjective test of Code Section 302(b)(1); 
(ii) the selling shareholder is not an officer, director, or employee of USB 
and he or she waives the family attribution rules of Code Section 318, 
thereby causing the transaction to be a complete termination of his or her 
interest; or (iii) the shareholder's proportionate interest in the 
corporation (counting directly owned and constructively owned shares) after 
the transaction is less than 50% of the total combined voting power of all 
classes of stock entitled to vote and the shareholder's proportionate voting 
interest before the transaction is less than 80% of such shareholder's 
proportionate voting interest after the transaction.  The tax authorities are 
not fully settled on the issue, but it is probable that this test would be 
applied at the USB level, AS IF the dissenting shareholder received the USB 
shares to which he or she would have been entitled in the merger, and then 
the shares were redeemed by USB.  Shareholders considering the exercise of 
their dissenter's rights should seek advice from their personal tax advisor 
on thisissue.
    

  The foregoing is only a general description of certain anticipated federal 
income tax consequences of the Merger, without regard to the particular facts 
and circumstances of the tax situation of each shareholder of Zappco.  It 
does not discuss all of the consequences that may be relevant to shareholders 
of Zappco entitled to special treatment under the Code (such as insurance 
companies, dealers in securities, exempt organizations or foreign persons) or 
to shareholders of Zappco who acquired their Zappco Common Stock pursuant to 
the exercise of employee stock options or otherwise as compensation.  The 
summary set forth above does not purport to be a complete analysis of all 
potential tax effects of the transactions contemplated by the Merger 
Agreement or the Merger itself.  No information is provided herein with 
respect to the tax consequences, if any, of the Merger under state, local, 
foreign or other tax laws.

STOCK EXCHANGE LISTING OF USB COMMON STOCK

  It is a condition to the obligation of Zappco to consummate the Merger
pursuant to the Merger Agreement that the shares of USB Common Stock which are
issuable upon consummation of the Merger shall have been approved for listing on
the NYSE subject to notice of issuance.  USB anticipates that such application
will be approved subject to notice of issuance at or before the Effective Date.

NONCOMPETITION AGREEMENTS

  Simultaneously with the execution of the Merger Agreement, each of Edward J.
Zapp and John Leisen entered into a Noncompetition Agreement with USB providing
that such individuals shall not, for a period of five years after the Effective
Date, (i) engage in the banking or financial services business as an advisor,
employee, consultant, agent, partner, principal, director, owner or stockholder
of any corporation or other business entity within a 50-mile radius of the main
office and each of the branch offices of the Banks (subject to certain
exceptions); (ii) directly or indirectly solicit the banking or financial
services business of any past or present customer of any Bank or encourage any
such customer to terminate or alter such customer's relationship with any Bank
(or its successor by merger); or (iii) directly or indirectly, hire for
employment any individual who, as of the date of the Merger Agreement, was an
employee or agent of Zappco or any Bank or who subsequent to the date of the
Merger Agreement became an employee of Zappco or any Bank (or any successors by
merger) (subject to certain exceptions).  Messrs. Zapp and Leisen each received
separate consideration for entering into these agreements to be paid by USB in
an annual amount of $200,000 for approximately eight and seven

                                     37

<PAGE>

years, respectively, subject to annual adjustment and subject to each such 
individual's compliance therewith, and certain retiree medical benefits as 
provided therein.

USB ESCROW DEPOSIT

  Prior to the execution of the Merger Agreement, and in consideration for
certain covenants and agreements set forth in a letter agreement previously
entered into by and among USB and Zappco setting forth the general provisions of
the Merger Agreement, USB deposited $500,000 (the "Option Deposit") in an escrow
account.  Upon execution of the Merger Agreement, USB deposited $1,000,000 (the
"Escrow Deposit") in an escrow account for the benefit of Zappco pursuant to the
deposit escrow agreement attached as Exhibit B to the Merger Agreement, plus the
Option Deposit (the Escrow Deposit together with the Option Deposit being
hereinafter referred to as the "USB Deposit").  If the Effective Date is delayed
beyond February 28, 1998 or if the Merger shall not have been consummated for
any reason on or prior to such date (unless the failure to consummate the Merger
by such date shall be due to the action or failure to act of Zappco in breach of
Zappco's obligations under the Merger Agreement), other than the termination of
the Merger Agreement due to a failure to satisfy certain conditions therein, the
USB Deposit, together with interest thereon, shall be paid to Zappco on the
earlier of such termination or such date.  If the Effective Date is on or before
February 28, 1998, the USB Deposit shall be refunded to USB.  If the Merger
Agreement is terminated at any time due to a failure to satisfy certain
conditions therein, or if the Merger shall not have been consummated due to the
action or failure to act of Zappco, the USB Deposit shall be refunded to USB. 
Interest on the USB Deposit shall be paid to the party to be paid the USB
Deposit as detailed above.  Any fees of the escrow deposit agent shall be paid
by the party receiving the interest on the USB Deposit.

RESALE OF USB COMMON STOCK RECEIVED BY ZAPPCO SHAREHOLDERS

   
  The USB Common Stock issuable to holders of Zappco Common Stock upon 
consummation of the Merger has been registered under the Securities Act, and 
will be transferable freely and without restriction by those holders of 
Zappco Common Stock who receive such shares following consummation of the 
Merger and who are not deemed to be "affiliates" (as defined under the 
Securities Act). Zappco has agreed in the Merger Agreement to use its best 
efforts to obtain signed Representation Letters from all of the shareholders 
of Zappco to the effect that it is each such holder's plan and intent to hold 
(and not to sell, transfer or otherwise dispose of) at least 50% of the 
shares of USB Common Stock issued to him pursuant to the Merger; provided, 
however, in the event that the proposed U.S. Treasury regulation regarding 
the "continuity of interest" test applicable to transactions intending to 
qualify as reorganizations within the meaning of Section 368(a) of the Code 
are adopted as final regulations in substantially the form in which they were 
proposed December 20, 1996 with an effective date of such regulations prior 
to the Effective Date, Zappco's obligation to use its best efforts to obtain 
such Representation Letters will terminate.
    

  Shares of USB Common Stock received by those shareholders of Zappco who are 
deemed to be "affiliates" of Zappco at the time of the Special Meeting may be 
resold without registration under the Securities Act only as permitted by 
Rule 145 under the Securities Act or as otherwise permitted under the 
Securities Act. Zappco has agreed in the Merger Agreement to use its best 
efforts to obtain and deliver to USB prior to the Effective Date signed 
Affiliate Letters (in the form attached as Exhibit A to the Merger Agreement) 
from each shareholder of Zappco who may reasonably be deemed to be an 
"affiliate" of Zappco to the effect that such persons will not offer to sell, 
transfer or otherwise dispose of any of the shares of USB Common Stock 
distributed to them pursuant to the Merger except in compliance with Rule 
145, or in a transaction that is otherwise exempt from the registration 
requirements of the Securities Act, or in an offering which is registered 
under the Securities Act.  This Proxy Statement/Prospectus does not cover any 
resales of USB Common Stock received by persons who are deemed to be 
"affiliates" of Zappco.  No person is authorized to make use of this Proxy 
Statement/Prospectus in connection with any such resales.  Former 
shareholders of Zappco who are deemed to be "affiliates" of Zappco and who 
surrender certificates formerly evidencing shares of

                                      38

<PAGE>

Zappco Common Stock must execute and deliver to USB a letter containing the 
representations described above before any exchange of such certificates for 
Merger Consideration will be effected. See "--Surrender of Zappco Common 
Stock Certificates."

  Until the second anniversary of the Effective Date, upon request, USB has
agreed to purchase from the former shareholders of Zappco up to an aggregate of
30% of the total number of shares of USB Common Stock issued upon conversion of
Zappco Common Stock in the Merger.  The purchase price for each such share
purchase by USB shall be equal to the closing price of a share of USB Common
Stock as quoted on the NYSE on the trading day immediately prior to the day on
which such purchase occurs.  At any such time as USB has purchased from former
Zappco shareholders a number of shares of USB Common Stock representing 30% of
the total number of shares issued pursuant to the Merger, USB's obligation to
purchase shares shall cease.  In addition, USB may, it is sole and absolute
discretion, suspend its obligation to purchase shares in the event of
restrictions imposed by federal securities laws or accounting requirements for
transactions accounted for as a pooling-of-interests.

USB DIVIDEND REINVESTMENT AND COMMON STOCK PURCHASE PLAN

  USB provides eligible shareholders with a simple and convenient method of
investing cash dividends and optional cash payments at 100% of the average price
(as defined) in additional shares of USB Common Stock without payment of any
brokerage commission or service charge pursuant to its Automatic Dividend
Reinvestment and Common Stock Purchase Plan.  The plan includes certain dollar
limitations on participation and provides for eligible shareholders to elect
dividend reinvestment on only a part of the shares registered in the name of a
participant (while continuing to receive cash dividends on remaining shares). 
It is anticipated that the plan will continue after the Effective Date and that
shareholders of Zappco who receive USB Common Stock in the Merger will have the
right to participate therein.

ACCOUNTING TREATMENT

  The Merger will be accounted for by USB under the purchase method of
accounting in accordance with Accounting Principles Board Opinion No. 16,
"Business Combinations," as amended.  Under this method of accounting, the
purchase price will be allocated to assets acquired and liabilities assumed
based on their estimated values.  Income of the combined company will not
include income or loss of Zappco prior to the Effective Date.

EXPENSES

  The Merger Agreement provides that all costs and expenses incurred in
connection with such agreement and the transactions contemplated thereby shall
be paid by the party incurring such costs and expenses; provided, however, USB
has agreed to reimburse Zappco in an amount not to exceed $200,000 (excluding
the cost of obtaining the Fairness Opinion) for costs and expenses incurred in
connection with such agreement and the transactions contemplated thereby, and
for the cost of obtaining the Fairness Opinion.  Additionally, USB has agreed to
bear the costs of all filing fees associated with the Registration Statement and
the costs of qualifying the shares of USB Common Stock under state securities
laws, to the extent necessary, as well as all printing and mailing costs in
connection with the preparation and mailing of this Proxy Statement/Prospectus
to Zappco shareholders.

CERTAIN DIFFERENCES IN RIGHTS OF ZAPPCO SHAREHOLDERS

  The rights of holders of Zappco Common Stock are governed by the Articles of
Incorporation of Zappco, as amended (the "Zappco Articles"), the bylaws of
Zappco (the "Zappco Bylaws") and the laws of the State of Minnesota.  The rights
of USB shareholders are governed by the Restated Certificate of Incorporation of
USB, as amended (the "USB Certificate"), the bylaws of USB (the "USB Bylaws")
and the laws of the State of Delaware.  After the Effective Date, the rights of
holders

                                      39

<PAGE>

of Zappco Common Stock will be governed by the USB Certificate, the USB 
Bylaws and the laws of the State of Delaware.  Because of certain differences 
between Minnesota and Delaware corporate law and between the Zappco Articles 
and Zappco Bylaws, on the one hand, and the USB Certificate and the USB 
Bylaws, on the other hand, the current rights of Zappco shareholders will 
change significantly as a result of the Merger.  While it is not practical to 
describe all changes in the rights of Zappco shareholders that will result 
from the Merger, the following is a summary of the material differences.

  BUSINESS COMBINATIONS AND SUPERMAJORITY VOTING.  Under Delaware law, a
corporation is prohibited from engaging in certain business combinations,
including a merger, sale of substantial assets, loan or substantial issuance of
stock, with an interested shareholder, or an interested shareholder's affiliates
and associates, for a three-year period beginning on the date the interested
shareholder acquires 15% or more of the outstanding voting stock of the
corporation.  The restrictions on business combinations do not apply if the
board of directors gives prior approval to the transaction in which the 15%
ownership level is exceeded, the interested shareholder acquires at one time 85%
of the corporation's stock (excluding shares held by management or employee
stock plans in which employees do not have the effective power to tender stock)
or the business combination is approved by the board of directors and authorized
at a meeting of shareholders by the holders of at least 66 2/3% of the
outstanding voting stock, excluding shares owned by the interested shareholder. 
The USB Certificate requires the affirmative vote of the holders of not less
than 80% of the outstanding shares of USB entitled to vote in connection with
certain "Business Transactions" (as defined in the USB Certificate) involving a
"Related Person" (as defined in the USB Certificate).  The 80% shareholder vote
is not required if the Business Transaction meets certain "fair price" criteria
or in the event the "Continuing Directors" (as defined in the USB Certificate)
approve the transaction.  The USB Certificate also requires the vote of the
holders of at least 80% of the outstanding shares of USB entitled to vote
generally in the election of directors to add to, alter, change or repeal the
supermajority provisions.

  Minnesota law requires approval by the disinterested shareholders of any
"control share acquisition" of stock of an "issuing public corporation" if an
acquiror exceeds specified levels of ownership (20%, 33 1/3% and 50%) of the
stock of the target corporation.  This provision essentially requires a proxy
contest to approve such share acquisitions and delays the acquiror's purchase up
to 55 days while a special shareholders' meeting is held to vote on the
acquisition.  The definition of "control share acquisition" excludes cash tender
offers for all outstanding shares if the offer has been approved in advance by
the board of directors of the target corporation and acquisitions by employee
benefit plans. 
  
  Minnesota law restricts transactions with a shareholder (an "interested
shareholder") acquiring ten percent or more of the shares of a publicly held
(i.e., required to file Exchange Act reports) "issuing public corporation"
unless the share acquisition or the transaction has been approved by the
corporation's board of directors prior to the acquisition of the ten percent
interest.  An "issuing public corporation" is a corporation which has at least
50 shareholders.  For four years after the ten percent threshold is exceeded
(absent prior board approval), the corporation cannot have a merger, sale of
substantial assets, loan, substantial issuance of stock, plan of liquidation or
reincorporation involving the interested shareholder or its affiliates.

  DISSENTERS' RIGHTS.  Under Delaware law, appraisal rights are available 
only in connection with certain statutory mergers or consolidations, unless 
the certificate of incorporation grants such rights with respect to 
amendments to its certificate of incorporation, any merger or consolidation 
in which the corporation is a constituent corporation, or sales of all or 
substantially all of the assets of a corporation.  The USB Certificate does 
not grant such rights. Appraisal rights under Delaware law, however, are not 
available if the corporation's stock is (prior to the relevant transaction) 
listed on a national securities exchange or designated as a national market 
system security on an interdealer quotation system by the National 
Association of Securities Dealers, Inc. or held of record by more than 2,000 
shareholders; provided that, if the merger or consolidation requires 
shareholders to exchange their stock for anything other than shares of the 
surviving or resulting corporation, for shares of another

                                      40
<PAGE>

corporation which will be listed on a national securities exchange or held by 
more than 2,000 shareholders, for cash in lieu of fractional shares of any 
such corporation, or for a combination of such shares and cash, then 
appraisal rights will be available.

  Minnesota law also makes appraisal rights available to dissenting 
shareholders in the event of any of the following actions: (i) an amendment 
of the articles of incorporation that materially and adversely affects the 
rights and preferences of the shares of the dissenting shareholder in certain 
respects; (ii) a sale or transfer of all or substantially all of the assets 
of the corporation; (iii) a plan of merger to which the corporation is a 
party; (iv) a plan of exchange of shares to which the corporation is a party; 
and (v) any other corporation action with respect to which the corporation's 
articles of incorporation or bylaws give dissenting shareholders the right to 
obtain payment for their shares.  The Zappco Articles do not grant any other 
dissenters' rights.  For a description of appraisal rights provided by 
Minnesota law in the event of a merger, see "Rights of Dissenting 
Shareholders." 

  ADVANCE NOTICE OF SHAREHOLDER NOMINATIONS FOR DIRECTORS AND PROPOSALS.  The 
USB Bylaws require that any shareholder nominating a person for election as a 
director must give written notice to the secretary of USB not less than 
ninety days prior to an annual meeting of shareholders or not less than seven 
days after the date on which notice of a special meeting of shareholders for 
the election of directors is given.  The USB Bylaws contain no advance notice 
requirements relating to shareholder proposals for business to be conducted 
at a shareholders meeting.  Neither the Zappco Articles nor Bylaws require 
notice for nomination by a shareholder of a director or notice for 
shareholder proposals for business to be conducted at a shareholders' meeting.

  AMENDMENTS TO CHARTER AND BYLAWS.  Under Delaware law, a corporation's 
certificate of incorporation may be amended by resolution of the board of 
directors and the affirmative vote of the holders of a majority of the 
outstanding shares entitled to vote.  Delaware law reserves the power to 
amend or repeal the bylaws exclusively to the shareholders unless the 
certificate of incorporation confers such power upon the directors.

  Under Minnesota law, the articles of incorporation may be amended by the 
greater of (i) a majority of the voting power present and entitled to vote on 
an item, or (ii) a majority of the voting power of the minimum number of 
shares entitled to vote that would constitute a quorum for the transaction of 
business at the meeting.   Minnesota law also entitles holders of shares of a 
class or series to vote as a class or series on any amendment which would (a) 
change the number of authorized shares of such class or series, (b) change or 
adversely affect the rights and preferences of such class or series, (c) 
create a new class or series of shares with rights and preferences prior and 
superior to such class or series, or (d) increase the rights and preferences 
of any class or series with prior and superior rights and preferences to such 
class or series.

  Minnesota law grants the power to adopt and amend bylaws to the board of 
directors unless the power is reserved exclusively for shareholders in the 
charter; provided, however, that Minnesota law has a limitation on the power 
of the board of directors to adopt or amend bylaws which is not contained in 
the Delaware statute.  After the adoption of initial bylaws, the board of a 
Minnesota corporation may not adopt, amend or repeal a bylaw fixing a quorum 
for meetings of shareholders, prescribing procedures for removing directors 
or filling vacancies in the board, or fixing the number of directors or their 
classifications, qualifications or terms of office except that the board may 
adopt or amend a bylaw to increase the number of directors.  This limitation 
occasionally prevents the board from changing certain governance provisions 
(or even adopting an updated set of bylaws that happens to change the wording 
of such provisions) without the expense of shareholder approval.  The 
shareholder approval requirement does not turn on the materiality or adverse 
nature to shareholders of a change.  Any change triggers the requirement.

  Minnesota law also requires that a resolution proposed by the holders of 3%
or more of the voting power of shares calling for adoption, amendment or repeal
of a bylaw must be presented to shareholders


                                      41

<PAGE>

as in the case of amendments to the articles of incorporation.  Delaware law 
does not specify the requirements for shareholder initiation of amendments to 
the bylaws.

  The USB Certificate provides that the USB Bylaws may be amended or repealed 
by the Board of Directors of USB, subject to the power of the shareholders to 
amend or repeal any such change to the USB Bylaws.  The Zappco Bylaws provide 
that the Zappco Bylaws may be amended or altered by majority vote of the 
whole Board of Directors at any meeting, provided that notice of a proposed 
amendment have been given to the directors of such a meeting.  The authority 
of the Zappco Board of Directors is subject to the power of the shareholders 
to change or repeal such Zappco Bylaws by a majority vote of the shareholders 
present and represented at any annual meeting or at any special meeting 
called for such purpose, and the Board of Directors may not make or alter any 
Zappco Bylaws fixing their number, qualifications or terms of office.

  PREEMPTIVE RIGHTS.  A preemptive right allows a shareholder to maintain its 
proportionate share of ownership of a company by permitting such shareholder 
the right to purchase a proportionate share of any new stock issuance and 
thereby protecting the shareholder from dilution of value and control upon 
new stock issuances.  

  Unless the certificate of incorporation provides otherwise, under Delaware 
law, shareholders of a corporation have no preemptive rights.  The USB 
Certificate contains no such provision for preemptive rights.  Minnesota law 
provides that all security holders are entitled to preemptive rights unless 
the articles of incorporation specifically deny or limit preemptive rights.  
Under the Zappco Articles, no holder of stock of Zappco has any preemptive 
rights.

  ACTION BY WRITTEN CONSENT.  Delaware law provides that, unless otherwise 
provided in the certificate of incorporation, shareholders may act by the 
written consent of the holders of not less than the minimum number of shares 
that would be necessary to approve such action at a meeting where all shares 
entitled to vote were present and voted.  The USB Certificate provides that 
USB shareholders may not act by written consent.

   
  Under Minnesota law, any action required or permitted to be taken in a 
meeting of the shareholders may be taken without a meeting by a written 
action signed by all of the shareholders.  The Zappco Articles do not 
restrict shareholder action by written consent.
    

  VOTING RIGHTS IN THE ELECTION OF DIRECTORS.   In an election of directors 
for corporations for which cumulative voting is provided, each share of stock 
normally having one vote is entitled to a number of votes equal to the number 
of directors to be elected.  A shareholder may then cast all such votes for a 
single candidate or may allocate them among as many candidates as the 
shareholder may choose.  Without cumulative voting, the holders of a majority 
of shares voting in the election of directors would have the power to elect 
all the directors to be elected, and no person could be elected without the 
support of holders of a majority of the shares. 

  Under Delaware law, a corporation's certificate of incorporation may 
provide for cumulative voting in the election of directors.  The USB 
Certificate does not provide for cumulative voting.  

  Under Minnesota law, cumulative voting for the election of directors is 
required unless specifically limited or denied in the articles of 
incorporation. The Zappco Articles prohibit cumulative voting in the election 
of directors.

  NUMBER OF DIRECTORS, VACANCIES AND NEWLY-CREATED DIRECTORSHIPS.  Under
Delaware law, the number of directors shall be fixed by or in the manner
provided in the bylaws, unless the certificate of incorporation fixes the number
of directors, in which case a change in the number of directors shall be made
only by amendment to the certificate.  Unless otherwise provided in the
certificate of incorporation or bylaws, vacancies and newly created
directorships resulting from any increase in the

                                      42

<PAGE>

authorized number of directors elected by all of the stockholders having the 
right to vote as a single class may be filled by a majority of the directors 
then in office, although less than a quorum, or by a sole remaining director. 
The USB Certificate provides that the number of directors shall be fixed by 
the USB Bylaws, and shall not be less than 12 nor more than 30.

  The USB Certificate provides that vacancies and newly-created directorships
resulting from an increase in the number of USB directors shall be filled only
by a majority of the directors then in office, although less than a quorum, or
by the sole remaining director.  The USB Certificate also provides that this
provision may not be amended or repealed unless approved by the affirmative vote
of holders of not less than 80% of the outstanding voting stock of USB. 
However, the USB Certificate exempts from its 80% shareholder voting requirement
any future amendment to the USB Certificate to reduce the maximum number of USB
directors to not less than the greater of (i) the number of directors then in
office and (ii) 24.

  Under Minnesota law, the minimum number of directors is one.  Minnesota law 
permits the number of directors to be fixed by the articles of incorporation 
or bylaws, and the number of directors may be increased or decreased by the 
shareholders of the board in the manner permitted by the articles of 
incorporation or bylaws.  Under the Zappco Bylaws, the number of directors 
shall not be less than one nor more than seven; provided, however, that in 
the event all of the shares of the corporation are owned beneficially and of 
record by more than one shareholder, the number of directors shall be no less 
than three.  

  Under Minnesota law, unless different rules for filling vacancies are
provided for in the articles of incorporation or bylaws, vacancies resulting
from the death, resignation, removal or disqualification of a director may be
filled by the affirmative vote of a majority of the remaining directors, even
though less than a quorum, and vacancies resulting from a newly-created
directorship may be filled by the affirmative vote of a majority of the
directors serving at the time of the increase.  The shareholders may also elect
a new director to fill a vacancy that is created by the removal of a director by
the shareholders.  The Zappco Bylaws provide that if any vacancies exist by
reason of death, resignation, or otherwise, a majority of the remaining
directors shall constitute a quorum for the filling of such vacancies.

  CLASSIFICATION OF BOARD.  A classified board of directors is one in which a
certain number, but not all, of the directors are elected on a rotating basis
each year.  This method of electing directors makes changes in the composition
of the board of directors, and thus a potential change in control of a
corporation, a lengthier and more difficult process.

  As permitted by Delaware law, the USB Certificate provides for
classification of the USB Board into three classes of directors with each class
as nearly equal in number as possible and elected for a three-year term and only
one class standing for election each year.  The affirmative vote of the holders
of at least 80% of the outstanding voting stock of USB is required to amend or
repeal this provision. 

  Minnesota law permits, but does not require, a classified board of
directors, with the terms of any such classes to be provided for in the articles
of incorporation and bylaws.  Neither the Zappco Articles nor Bylaws provide for
a classified board of directors.
 
  REMOVAL OF DIRECTORS.   Delaware law provides that a director or the entire
board of directors may be removed, with or without cause, by the holders of a
majority of the shares then entitled to vote at an election of directors, unless
the certificate of incorporation provides, in the case of a corporation whose
board is classified, that directors may be removed only for cause.  If the
corporation has cumulative voting, in which event if less than the entire board
is to be removed, no director may be removed without cause if the votes cast
against the director's removal would be sufficient to elect that director if
voted cumulatively either at an election of the entire board of directors or for
classes of the board.

                                      43

<PAGE>

Under the USB Certificate, USB shareholders may remove a director only for 
cause upon a majority vote of the shareholders.

  Under Minnesota law, a director of a corporation that does not have 
cumulative voting may be removed with or without cause with the approval of 
the holders of a majority of the outstanding shares entitled to vote at an 
election of directors.  In the case of a corporation having cumulative 
noting, if less than the entire board of directors is to be removed, a 
director may not be removed without cause unless the number of shares voted 
against such removal would not be sufficient to elect the director under 
cumulative voting.  The Zappco Articles do not contain provisions with 
respect to removal of directors.

  SPECIAL MEETINGS OF SHAREHOLDERS.  The USB Bylaws provide that special 
meetings may be called only by the Board of Directors or the Chief Executive 
Officer.  The Zappco Bylaws provide that special meetings of Zappco 
shareholders may be called by the Chairman of the Board of Directors, and 
shall be called by the President at the request of the holders of not less 
than 10% of the outstanding shares of Zappco entitled to vote at such 
meeting.  

  QUORUM AT SHAREHOLDERS' MEETINGS.  The USB Bylaws require that the holders 
of not less than one-third of the shares entitled to vote at any 
shareholder's meeting be present, in person or by proxy, to constitute a 
quorum.  The Zappco Bylaws provide that the holders of a majority of the 
outstanding shares entitled to vote at a meeting, represented in person or by 
proxy, shall constitute a quorum for purposes of such a meeting.  

  LIMITATION ON PERSONAL LIABILITY OF DIRECTORS.  The USB Certificate 
provides that directors of USB shall not be liable to USB or its shareholders 
for monetary damages for breaches of fiduciary duty; provided, however, that 
such liability of a director shall not be eliminated or limited to the extent 
provided by applicable law under certain circumstances.  The Zappco Articles 
do not contain such a provision.

  DIVIDENDS. Under Delaware law, dividends may be paid out of surplus or out 
of net profits for the fiscal year in which the dividend is paid or the 
preceding fiscal year, except that no dividends may be paid if the capital of 
the corporation has been diminished to an amount less than the liquidation 
preference of outstanding preferred stock.  Under the USB Certificate, 
holders of USB 8 1/8% Cumulative Preferred Stock are entitled to receive, 
when, as and if declared by the USB Board of Directors, cumulative cash 
dividends, payable quarterly in arrears, at the rate of 8 1/8% per share per 
annum.  See "Description of USB Capital Stock--Preferred Stock."

  Under Minnesota law, a corporation may make a distribution only if the board
of directors has determined that the corporation is able, and the corporation is
in fact able, to pay its debts in the ordinary course of business after making
the distribution.  A distribution may be made to holders of a class or series of
shares only if all amounts payable to holders of shares having a preference are
paid (except for those having waived rights to payment) and if payment of such
distribution does not reduce the net assets of the corporation below the
aggregate preferential amount payable upon liquidation (unless the distribution
is made to shareholders in the order of and to the extent of their respective
priorities). 

  GENERAL.  The foregoing discussion of certain similarities and material
differences between the rights of holders of Zappco Common Stock and the rights
of holders of USB Common Stock under the Articles and Certificate of
Incorporation, respectively, and Bylaws pursuant to Delaware and Minnesota law
is only a summary of certain provisions and does not purport to be a complete
description of such similarities and differences.  The foregoing discussion also
does not reflect any rules of the NYSE that may apply to USB.  The foregoing
discussion is qualified in its entirety by reference to the MBCA, the Delaware
Law, the common law thereunder, and the full texts of the Articles and
Certificate of Incorporation, respectively, and Bylaws of Zappco and USB.  Such
Articles, Certificate of

                                      44

<PAGE>

Incorporation and Bylaws are filed or incorporated by reference as exhibits 
to the Registration Statement of which this Proxy Statement/Prospectus is a 
part.

                            EXCESS PARACHUTE PAYMENTS
                                 (PROPOSAL NO. 2)

  The Merger Agreement provides that Zappco shall make no payments that 
separately or in the aggregate could or would result in the payment of any 
"excess parachute payments" within the meaning of Section 280G of the Code, 
unless and until such payments are approved by Zappco's shareholders in 
accordance with the provisions of Sections 280G(b)(5)(A)(ii) and 
280G(b)(5)(B) of the Code.  Generally speaking, 280G Payments result when 
there is a change in control of an employer, such as contemplated by the 
Merger, and as a result, certain employee/officers receive compensation equal 
to or in excess of three times their average annual compensation for the five 
years preceding the taxable year in which the change in control occurs (the 
"base amount").  The excess of such "parachute payments" (i) will not be 
deductible by the payor and (ii) will be subject to an excise tax payable by 
the individual.  It is probable that (i) noncompete payments to be made by 
USB to Messrs. Zapp and Leisen, (ii) deferred compensation/salary 
continuation payments to be paid to Messrs. Zapp and Leisen under existing 
agreements between them and Zappco, and (iii) compensation payments to be 
made by USB to Mr. Leisen for continued employment would constitute 280G 
Payments.  Section 280G of the Code contains an exemption for payments by a 
corporation whose stock is not publicly traded on an established securities 
market if disinterested shareholders owning more than 75% of the voting power 
of such corporation's stock approve the payment.  In order to avoid the 
denial of deductibility and the imposition of the excise tax which applies to 
280G Payments, Zappco's shareholders are being asked to approve such 
payments.   Approval of the 280G Payments by Zappco's shareholders is a 
condition to consummation of the Merger, but will not affect the amount of 
the Merger consideration to be received.  For a discussion of the 
compensation to be received by Messrs. Zapp and Leisen, see "--Interests of 
Certain Persons in the Merger."

APPROVAL OF THE 280G PAYMENTS REQUIRES THE AFFIRMATIVE VOTE OF MORE THAN 75% OF
THE VOTING POWER OF ALL OUTSTANDING SHARES OF ZAPPCO COMMON STOCK, EXCLUDING 
THOSE SHARES HELD OR CONSTRUCTIVELY OWNED BY MESSRS. ZAPP AND LEISEN. THE 
BOARD OF DIRECTORS OF ZAPPCO RECOMMENDS THAT ZAPPCO SHAREHOLDERS VOTE FOR 
APPROVAL OF THE 280G PAYMENTS.  


                          RIGHTS OF DISSENTING SHAREHOLDERS

  Sections 302A.471 and 302A.473 of the MBCA provide to each shareholder the
right to dissent from the Merger and obtain payment for the "fair value" of such
shareholder's shares following the consummation of the Merger. 

  The following summary of the applicable provisions of Sections 302A.471 and 
302A.473 of the MBCA is not intended to be a complete statement of such 
provisions and is qualified in its entirety by reference to such sections, 
the full texts of which are attached as APPENDIX C to this Proxy 
Statement/Prospectus.  These sections should be reviewed carefully by any 
shareholder who wishes to exercise dissenters' rights or who wishes to 
preserve the right to do so, since failure to comply with the procedures set 
forth herein or therein will result in the loss of dissenters' rights.

  Under the MBCA, holders of Zappco Common Stock will have the right, by 
fully complying with the applicable provisions of Sections 302A.471 and 
302A.473, to dissent with respect to the Merger and to receive from the 
surviving corporation payment in cash of the "fair value" of their shares of 
Zappco Common Stock after the Merger is completed.  The term "fair value" 
means the value of the shares of Zappco Common Stock immediately before the 
Effective Date.

  All references in Sections 302A.471 and 302A.473 and in this summary to a
"shareholder" are to a record holder of the shares of Zappco Common Stock as to
which dissenters' rights are asserted.  A person having beneficial ownership of
shares of Zappco Common Stock that are held of record in the name of another
person, such as a broker, nominee, trustee or custodian, must act promptly to
cause the

                                      45

<PAGE>

record holder to follow the steps summarized below properly and in a timely 
manner in order to perfect whatever dissenters' rights such beneficial owner 
may have.

  If a date is fixed by the Zappco Board for the determination of 
shareholders entitled to receive notice of and to vote on the Merger 
Agreement, only shareholders and beneficial owners as of the Record Date may 
exercise dissenters' rights.

  Shareholders of record who desire to exercise their dissenters' rights must 
satisfy all of the following conditions.  A written notice of intent to 
demand fair value for shares must be delivered to the executive offices of 
Zappco before the taking of the shareholder vote on the Merger.  This written 
demand must be in addition to and separate from any proxy or vote against the 
Merger. Voting against, abstaining from voting or failing to vote on the 
Merger does not constitute a demand for appraisal within the meaning of the 
MBCA.

  Shareholders electing to exercise their dissenters' rights under the MBCA 
must not vote for adoption of the Merger.  A shareholder's failure to vote 
against the Merger will not constitute a waiver of dissenters' rights.  
However, if a shareholder returns a signed proxy but does not specify a vote 
against adoption of the Merger or direction to abstain, the proxy will be 
voted for adoption of the Merger, which will have the effect of waiving that 
shareholder's dissenters' rights.

  A Zappco shareholder may not assert dissenters' rights as to less than all 
of the shares registered in such holder's name except where certain shares 
are beneficially owned by another person but registered in such holder's 
name.  If a record owner, such as a broker, nominee, trustee or custodian, 
wishes to dissent with respect to shares beneficially owned by another 
person, such shareholder must dissent with respect to all of such shares and 
must disclose the name and address of the beneficial owner on whose behalf 
the dissent is made.  A beneficial owner of shares of Zappco Common Stock who 
is not the record owner of such shares may assert dissenters' rights as to 
shares held on such person's behalf, provided that such beneficial owner 
submits a written consent of the record owner to Zappco at or before time 
such rights are asserted.

   
  A shareholder who elects to exercise dissenters' rights must deliver 
his, her or its written demand, before the taking of the vote on the Merger, 
to Edward J. Zapp, President of Zappco, 1015 St. Germain St. West, St. Cloud, 
Minnesota 56302-0531. The written demand should specify the shareholder's 
name and mailing address, the number of shares owned and that the shareholder 
intends to demand the value of his or her shares.
    

  After approval of the Merger by the shareholders at the Special Meeting, 
USB, as the surviving corporation, will send a written notice to each 
shareholder who filed a written demand for dissenters' rights.  The notice 
will contain the address to which the shareholder shall send a demand for 
payment and the stock certificates in order to obtain payment and the date by 
which they must be received, a form to be used in connection therewith and 
other related information.

   
  In order to receive fair value for his, her or its shares, a dissenting 
shareholder must, within 30 days after the date such notice was given, send 
his or her stock certificates, and all other information specified in the 
notice from the surviving corporation, to the address specified in such 
notice.  A dissenting shareholder will retain all rights as a shareholder of 
Zappco until the Effective Date.  After a valid demand for payment and the 
related stock certificates and other information are received, or after the 
Effective Date, whichever is later, the surviving corporation will remit to 
each dissenting shareholder who has complied with statutory requirements the 
amount that the surviving corporation estimates to be the fair value of such 
shareholder's shares, with interest commencing five days after the Effective 
Date at a rate prescribed by statute.  Remittance will be accompanied by 
Zappco's closing balance sheet and statement of income for a fiscal year 
ending not more than 16 months before the Effective Date, together with the 
latest available interim financial data, an estimate of the fair value of the 
shareholder's shares and a brief description of the method used to reach the 
    
                                      46

<PAGE>

estimate, a brief description of the procedure to be followed if such holder 
is demanding supplemental payment and copies of Sections 302A.471 and 
302A.473 of the MBCA.

  If the dissenting shareholder believes that the amount remitted by the 
surviving corporation is less than the fair value of such holder's shares, 
plus interest, the shareholder may give written notice to the surviving 
corporation of such holder's own estimate of the fair value of the shares, 
plus interest, within 30 days after the mailing date of the remittance and 
demand payment of the difference.  A shareholder who fails to give such 
written notice within this time period is entitled only to the amount 
remitted by the surviving corporation.

  Within 60 days after receipt of a demand for supplemental payment, the 
surviving corporation must either pay the shareholder the amount demanded or 
agreed to by such shareholder after discussion with the surviving corporation 
or petition a court for the determination of the fair value of the shares, 
plus interest.  The petition shall name as parties all shareholders who have 
demanded supplemental payment and have not reached an agreement with the 
surviving corporation.  The court, after determining that the shareholder or 
shareholders in question have complied with all statutory requirements, may 
use any valuation method or combination of methods it deems appropriate to 
use, whether or not used by the surviving corporation or the dissenting 
shareholder, and may appoint appraisers to recommend the amount of the fair 
value of the shares.  The court's determination will be binding on all Zappco 
shareholders who properly exercised dissenters' rights and did not agree with 
the surviving corporation as to the fair value of the shares.  Dissenting 
shareholders are entitled to judgment for the amount by which the 
court-determined fair value per share, plus interest, exceeds the amount per 
share, plus interest, remitted to the shareholders by the surviving 
corporation.  The shareholders shall not be liable to the surviving 
corporation for any amounts paid by the surviving corporation which exceed 
the fair value of the shares as determined by the court, plus interest.  The 
costs and expenses of such a proceeding, including the expenses and 
compensation of any appraisers, will be determined by the court and assessed 
against the surviving corporation, except that the court may, in its 
discretion, assess part or all of those costs and expenses against any 
shareholder whose action in demanding supplemental payment is found to be 
arbitrary, vexatious or not in good faith.  The court may award fees and 
expenses to an attorney for the dissenting shareholders out of the amount, if 
any, awarded to such shareholders. Fees and expenses of experts or attorneys 
may also be assessed against any person who acted arbitrarily, vexatiously or 
not in good faith in bringing the proceeding.

  The surviving corporation may withhold the remittance of the estimated fair 
value, plus interest, for any shares owned by any person who was not a 
shareholder or who is dissenting on behalf of a person who was not a 
beneficial owner on September 15, 1997, the date on which the proposed Merger 
was first announced to the public (the "Public Announcement Date").  The 
surviving corporation will forward to any such dissenting shareholder who has 
complied with all requirements in exercising dissenters' rights the notice 
and all other materials sent after shareholder approval of the Merger to all 
shareholders who have properly exercised dissenters' rights, together with a 
statement of the reason for withholding the remittance and an offer to pay 
the dissenting shareholder the amount listed in the materials if the 
shareholder agrees to accept that amount in full satisfaction.  The 
shareholder may decline this offer and demand payment by following the same 
procedure as that described for demand of supplemental payment by 
shareholders who owned their shares as of the Public Announcement Date.  Any 
shareholder who did not own shares on the Public Announcement Date and who 
fails properly to demand payment will be entitled only to the amount offered 
by the surviving corporation.  Upon proper demand by any such shareholder, 
rules and procedures applicable in connection with receipt by the surviving 
corporation of the demand for supplemental payment given by a dissenting 
shareholder who owned shares on the Public Announcement Date will also apply 
to any shareholder properly giving a demand but who did not own shares of 
record or beneficially on the Public Announcement Date, except that any such 
shareholder is not entitled to receive any remittance from the surviving 
corporation until the fair value of the shares, plus interest, has been 
determined pursuant to such rules and procedures.

  Shareholders considering exercising dissenters' rights should bear in mind
that the fair value of their shares determined under Sections 302A.471 and
302A.473 of the MBCA could be more than, the same as or, in certain
circumstances, less than the consideration they would receive pursuant to the
Merger Agreement if they do not seek appraisal of their shares, and that the
opinion of any investment banking firm as to fairness, from a financial point of
view, is not an opinion as to fair value under Sections 302A.471 and 302A.473.

  Cash received pursuant to the exercise of dissenters' rights may be subject
to federal or state income tax.  See "The Merger--Certain Federal Income Tax
Consequences to Zappco Shareholders."

  ANY HOLDER WHO FAILS TO COMPLY FULLY WITH THE STATUTORY PROCEDURE SUMMARIZED
ABOVE WILL FORFEIT HIS OR HER RIGHTS OF DISSENT AND WILL RECEIVE THE MERGER
CONSIDERATION FOR HIS OR HER SHARES.  SEE APPENDIX C.

NET INTEREST INCOME

YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994

   Net interest income is Zappco's largest single source of earnings.  Net
interest income on a tax equivalent basis represents the difference between
interest earned on assets and interest paid on liabilities, with adjustments
made to reflect income on tax-exempt assets as if such income were fully
taxable.  Changes in the types and volume of earning assets and interest bearing
liabilities, their related yields and overall interest rates all can have a
significant impact on net interest income.

   For the year ended December 31, 1996, net interest income was $14.5 million,
an increase of $2.2 million, or 18.2%, over the year ended December 31, 1995. 
This increase was largely attributable to an 11.4% increase in average earning
assets from 1995 to 1996.  During 1996, net interest margin (net interest income
divided by average earning assets) increased from 4.8% to 5.1%.

   For the year ended December 31, 1995, net interest income was $12.3 million,
an increase of $0.5 million, or 3.8%, over the year ended December 31, 1994. 
This increase resulted from an increase in average interest earning assets of
3.9%.  During 1995, net interest margin remained at 4.8%.

SIX MONTHS ENDED JUNE 30, 1997 AND 1996

   For the six months ended June 30, 1997, net interest income was $7.2
million, an increase of $0.4 million, or 5.5%, over the same period in 1996. 
This increase resulted from continued growth in average earning assets,
particularly in the loan portfolio.

     For 1996, the increases in deposit service charges resulted primarily 
from an increased customer base and increased volumes.  The large increase in 
Non-Interest Income was due to interest income that was paid along with the 
settlement of a law suit with the State of Minnesota on improper taxing of U. 
S. Government and U. S. Agency securities.  The refund of income taxes is 
reflected in income tax expense in 1996.  The other portion of the increase 
is a settlement by the data processing center with a major vendor on their 
termination of support on a software package.

ALLOWANCE FOR LOAN LOSSES

     The Allowance for Loan Losses is maintained to reserve against inherent 
loan losses.  This allowance is subject to ongoing review and evaluation of 
the risk profiles of the portfolio, specific exposures and general economic 
trends.  The Allowance for Loan Losses at December 31, 1996 was $2.7 million, 
or 1.2% of loans outstanding, as compared to $2.5 million, or 1.3% of loans 
outstanding as of December 31, 1995 and $2.7 million, or 1.4% of loans 
outstanding as of December 31, 1994.  The Allowance for Loan Losses at 
June 30, 1997 was $2.5 million or 1.1% of loans outstanding.

     The Provisions for Loan Losses are determined based upon an evaluation and
analysis by management of Zappco of the adequacy of the allowance for loan
losses.  Provisions for Loan Losses are made in amounts to maintain the
allowance for loan losses at a level considered necessary to absorb estimated
loan losses in the loan portfolio.  Factors which are considered are the quality
of the current loan portfolio, estimates and appraisals of collateral values,
historical charge-offs experience, current economic conditions, and such other
factors which, in the judgment of management, deserve consideration.  The
appropriate level of Provision for Loan Loss is reviewed monthly by management
and the Board of Directors of Zappco.

   The December 31, 1996 Securities Portfolio of approximately $69.6 million 
consisted entirely of available-for-sale securities.  The December 31, 1995 
Securities Portfolio consisted of $71.1 million in available-for-sale 
securities and $2.0 million in held-to-maturity securities.  The total amount 
of investment securities decreased from $73.1 million to $69.6 million from 
December 31, 1995 to December 31, 1996.  During that same time period, the 
percentage of investment of U. S. Treasuries and U.S. Agencies securities 
decreased from 95.4% of the Securities Portfolio to 92.3%.  The decrease was 
primarily due to increased investments in the state and political portfolio.

   From December 31, 1996 to June 30, 1997, the Securities Portfolio 
increased from $69.6 million to $75.5 million, with the increase primarily in 
U. S. Agencies securities.  At June 30, 1997, the Securities Portfolio 
consisted of $73.6 million in available-for-sale securities and $1.9 million 
in held-to-maturity securities.  The increase in the portfolio balance was a 
result of an increase in deposits.

   The total Securities Portfolio increased from $60.6 million on December 31,
1994 to $73.1 million at December 31, 1995.

   Average deposits in 1996 were $253.0 million, a $33.0 million, or 15.0%,
increase over 1995.  The increases were principally a result of an increase in
the number of accounts.  In 1996, continued growth was experienced in almost all
categories except money market savings and other savings.

   For the first six months of 1997, average deposits increased 8.1% from the
1996 levels. 

OTHER BORROWED MONEY

   Other Borrowed Money consists of federal funds purchased, securities sold
under agreements to repurchase and borrowings from the Federal Home Loan Bank.

   Federal Funds are purchased from a correspondent bank at prevailing interest
rates.  Securities are sold to bank customers under repurchase agreements at
prevailing market rates.  Borrowing has been done with the Federal Home Loan
Bank since 1995 to provide funding for residential real estate.

   While it is the objective of Zappco to fund principally with core deposits,
other borrowings represent an important additional source of funding.  In the
normal course of providing banking services to customers, the Subsidiary banks
purchase federal funds from a correspondent bank.  Accordingly, balances in this
account will fluctuate depending on customer needs.  Due to the competitive
nature of the banking industry in St. Cloud, a more stable source of funding
Federal Home Loan Banks borrowings has been utilized primarily for residential
real estate loans.

   As of June 30, 1997, total Other Borrowed Money was $10.3 million, down $4.5
million, or approximately 30%, from December 31, 1996.

CAPITAL RESOURCES

   At December 31, 1996, common equity was $28.4 million, a 14.7% increase over
December 31, 1995, due to retention of earnings.  At June 30, 1997, common
equity had increased from the December 31, 1996 balance to $29.6 million, a $1.2
million or 4.2% increase.

</TABLE>


   In 1989, the Federal Reserve Board adopted supervisory risk-based capital
ratios to provide capital adequacy standards for U. S. banking organizations. 
The guidelines provided for a transition implementation period that ended at the
end of 1992 with required ratios increasing from 1990-1992.  Under these
guidelines, at December 31, 1993, the minimum Tier 1 Capital Ratio is 4.0% and
the minimum Total Risk Adjusted Capital Ratio is 8.0%.  As shown in the table
above, Tier 1 and Total Risk Adjusted Capital Ratios were 9.9% and 10.92%,
respectively, at December 31, 1996, 10.1% and 11.03 respectively at June 30,
1997.

   In late 1990, the Federal Reserve Board adopted a new minimum leverage ratio
of 3.0% Tier 1 Capital to Total Assets.  The definition of Tier 1 Capital for
the leverage ratio is the same as the December 31, 1992 Tier 1 Capital
definition in the risk-based capital guidelines.  However, the new leverage
ratio establishes 3.0% as a minimum at which only the top-rated banking
organizations with a composite rating of "1" may operate.  Other institutions
will be required to maintain leverage ratios generally in the range of at least
100 to 200 basis points above the minimum level.  At June 30, 1997, December 31,
1996 and December 31, 1995, the leverage ratio was 8.38%, 8.16% and 7.74%,
respectively.

INTEREST RATE RISK MANAGEMENT

   Interest Rate Risk is the exposure of earnings and capital arising from
changes in interest rates.  The function of Interest Rate Risk Management is to
effectively coordinate the management of interest risk and net interest margin
of Zappco.  Management's goal is to maximize net interest margin while
maintaining interest rate risk within policy guidelines.  Management
accomplishes this objective by:  1) matching the rate sensitivity of assets and
liabilities; 2) selecting assets which meet acceptable credit risk/interest rate
risk/liquidity risk parameters and maximize yield; and 3) maintaining that mix
of liabilities which minimizes interest expense and limits liquidity exposure. 
By positioning assets and liabilities according to this policy, management
expects to minimize interest rate risk, lock in a positive spread in each time
period and protect net interest income regardless of interest rate volatility,
level or direction.

   It is the responsibility of the Subsidiary banks Asset/Liability Management
Committee ("ALCO") to monitor and manage its exposure to net interest income due
to fluctuating interest rates.

                                       63

<PAGE>

ALCO operates under policies to review and monitor the composition of the 
balance sheet generally and for specific management of investment assets, 
purchased liabilities and off-balance sheet transactions.  ALCO attempts to 
achieve stable net interest margins by matching the balance of assets and 
liabilities maturing or repricing in given periods and by adjusting rates to 
market conditions and changing interest rates.

INTEREST RATE RISK MANAGEMENT GUIDELINES

   To limit Zappco's interest rate risk exposure and to protect net interest
margin, the ALCO monitors the following interest rate risk measures on a monthly
basis and maintains these measures within the respective guidelines listed as
follows:

           MEASURES                               GUIDELINES
   CUMULATIVE GAP (% OF ASSETS)                 ACCEPTABLE RANGE

   1 - 360 Days                                       +/- 15%
   1 - 3 Years                                        +/- 15%
   3 - 7 Years                                        +/- 15%
   7 - 15 Years                                       +/- 15%
   15 Years Plus                                      +/- 15%
   Loan/Deposit Ratio                                   < 85%
   Total Risk Based Capital                             > 10%

   Management recognizes that acceptance of interest rate risk is a normal part
of banking operations.  However, excessive interest rate risk will expose
earnings and capital to potential losses.  Additionally, it is not always
possible to maintain perfectly matched positions nor is it always in the best
interest of the institution.  Therefore, management maintains the match between
assets and liabilities within the above guidelines to protect earnings and 
capital and provide flexibility in operations.

LIQUIDITY

   The function of Liquidity Management is to ensure that adequate liquidity is
maintained at all times.  Management's goal will be to maintain liquidity levels
that cover normal cyclical swings in deposit/loan demand as well as abnormal and
unexpected needs.  The liquidity of Zappco will be based upon the specific mix
of assets and liabilities and their respective historical volatility. 
Management recognizes the need to balance liquidity and income and will avoid
maintaining excess liquidity.

   Primary Reserves consist of vault cash and deposits due from banks.  Legal
or minimum reserves are established by law.  Bank management monitors reserve
requirements and available primary reserves, maintaining sufficient margin to
cover daily requirements and unusual demand days.

   Secondary Reserves consist of investments serving as a source of funds to
meet customer needs and a source of income before those needs materialize. 
Normal liquidity needs are met with the following investments maturing within
one year.

   A.  U. S. Treasury Obligations (bills, notes, bonds)

   It is the policy of Zappco to manage its funds to ensure that liquidity
needs are fully satisfied through normal bank operations.  To ensure adequate
liquidity is maintained, management monitors liquidity utilizing the following
calculations and maintain these measures within the listed guidelines:

   In addition, the Subsidiary banks will maintain an unsecured Federal Funds 
line of credit totaling $6.0 million with upstream correspondent banks, but 
will not rely on this line except during short-term seasonal peaks in demand. 
Should it become necessary, Zappco will secure its Federal Fund borrowings 
by pledging investment securities or other eligible assets.

   Deposit volatility is monitored through trend reports developed for and 
reviewed by the Bank's Asset/Liability Management Committee.  Customer's needs
for credit are closely monitored with monthly summaries of unfunded loan 
commitments and anticipated loan commitments reviewed by the Asset/Liability 
Management Committee.  If necessary, each Bank may pay national rates for large
depositors including county and municipal government, school districts or 
commercial customers.  Under no circumstances, without the proper written 
consent of the Zappco Board of Directors, will a Bank use brokered funds to 
improve short-term liquidity.

                        DESCRIPTION OF USB CAPITAL STOCK
                                           
   The following description of the capital stock of USB does not purport to 
be complete and is subject, in all respects, to applicable Delaware law and 
to the provisions of the USB Certificate.  The following description is 
qualified by reference to the USB Certificate, the certificate of designation 
for each series of preferred stock of USB, and the agreements and documents 
referred to below under "--Periodic Stock Purchase Rights and Risk Event 
Warrants," copies of which are incorporated by reference as exhibits to the 
Registration Statement of which this Proxy Statement/Prospectus is a part.

GENERAL

   The authorized capital stock of USB consists of 500,000,000 shares of USB 
Common Stock, par value $1.25 per share, and 10,000,000 shares of preferred 
stock, par value $1.00 per share.  Under the USB Certificate, the USB Board 
of Directors or a duly authorized committee thereof has the power, without 
further action by the shareholders, unless action is required by applicable 
laws or regulations, to provide for the issuance of preferred stock in one or 
more series and to fix the voting rights, designations, preferences, and 
relative, participating, optional or other special rights, and 
qualifications, limitations or restrictions thereof by adopting a resolution 
or resolutions creating and designating such series.  

   
    As of the Record Date, 245,472,252 shares of USB Common Stock were 
issued, 24,032,809 shares were reserved for issuance under USB's employee and 
director plans and the USB Reinvestment and Purchase Plan, 44,701 shares were 
reserved for issuance under outstanding warrants to purchase USB Common Stock 
and 15,000,000 shares were reserved for issuance upon exercise of the 
Periodic Stock Purchase Rights and Risk Event Warrants described below.  As 
of the Record Date, there were 6,000,000 shares of preferred stock of USB 
outstanding and 12,750 shares of preferred stock of USB reserved for issuance.
    

PREFERRED STOCK

   
   USB presently has one series of preferred stock issued and outstanding and 
one series of preferred stock authorized for future issuance.  As of the 
Record Date, USB had 6,000,000 shares of USB 8 1/8% Cumulative Preferred 
Stock, Series A, outstanding (the "USB 8 1/8% Preferred Stock") and 12,750 
shares of its Series 1990A Preferred Stock reserved for issuance.  On October 
15, 1997, USB announced that it had called for redemption all of the 
outstanding shares of its USB 8 1/8% Preferred Stock.  The shares will be 
redeemed on November 14, 1997 at a redemption price of $25.00 per share, 
together with accrued and unpaid dividends from August 15, 1997 to November 
14, 1997.  From and after November 14, 1997, dividends will cease to accrue 
and be payable on the USB 8 1/8% Preferred Stock.  See "--USB 8 1/8% 
Preferred Stock--Redemption."
    

   USB 8 1/8% PREFERRED STOCK

   RANK.  The USB 8 1/8% Preferred Stock ranks on a parity as to payment of
dividends and distribution of assets upon dissolution, liquidation or winding up
of USB with the shares of each other currently outstanding series of preferred
stock of USB.  The USB 8 1/8% Preferred Stock ranks prior to the USB Common
Stock with respect to the payment of dividends and distribution of assets upon
dissolution, liquidation or winding up of USB.

   DIVIDENDS.  Holders of shares of USB 8 1/8% Preferred Stock are entitled to
receive, when, as and if declared by the USB Board, or a duly authorized
committee thereof, out of assets of USB legally available for payment,
cumulative cash dividends, payable quarterly in arrears, at the rate of 8 1/8%
per share per annum.  Dividends on the USB 8 1/8% Preferred Stock are payable
quarterly on the fifteenth of February, May, August and November of each year
(each, a "Dividend Payment Date").  Each declared dividend shall be payable to
holders of record as they appear at the close of business on the stock books of
USB on such record dates, not more than 45 calendar days preceding the payment
dates therefor, as are determined

                                      67

<PAGE>

by the USB Board.  Quarterly dividend periods shall commence on and include 
the Dividend Payment Date and shall end on and include the day next preceding 
the next following Dividend Payment Date.  The right of holders of USB 8 1/8% 
Preferred Stock to receive dividends is cumulative.

   No full dividends will be declared or paid or set aside for payment on any 
stock of USB ranking, as to dividends, on a parity with or junior to the USB 
8 1/8% Preferred Stock for any period unless full cumulative dividends on the 
USB 8 1/8% Preferred Stock have been or contemporaneously are declared and 
paid or declared and a sum sufficient for the payment thereof set aside for 
such payment on the USB 8 1/8% Preferred Stock for all dividend periods 
terminating on or prior to the date of payment of such dividends.  When 
dividends are not paid in full on the USB 8 1/8% Preferred Stock and any 
other preferred stock of USB ranking on a parity as to dividends with the USB 
8 1/8% Preferred Stock, all dividends declared or paid upon shares of the USB 
8 1/8% Preferred Stock and such other preferred stock shall be declared and 
paid pro rata so that the amount of dividends declared and paid per share on 
the USB 8 1/8% Preferred Stock and such other preferred stock shall in all 
cases bear to each other the same ratio that accrued dividends per share 
(which in the case of noncumulative preferred stock shall not include any 
accumulation in respect of unpaid dividends for prior dividend periods) on 
shares of the USB 8 1/8% Preferred Stock and such other preferred stock bear 
to each other.  Except as provided in the preceding sentence, unless full 
cumulative dividends on the USB 8 1/8% Preferred Stock have been paid or 
declared and set aside for payment, no dividends (other than dividends or 
distributions paid in shares of, or options, warrants or rights to subscribe 
for or purchase shares of, USB Common Stock or any other stock of USB ranking 
junior to the USB 8 1/8% Preferred Stock as to dividends and upon 
liquidation) shall be declared or paid or set aside for payment or any other 
distribution declared or made upon the USB Common Stock or any other stock of 
USB ranking junior to or on a parity with the USB 8 1/8% Preferred Stock as 
to dividends or upon liquidation.  No USB Common Stock or any other stock of 
USB ranking junior to or on a parity with the USB 8 1/8% Preferred Stock as 
to dividends or upon liquidation shall be redeemed, purchased or otherwise 
acquired for any consideration (and no moneys shall be paid to or made 
available for a sinking fund for the redemption of any shares of any such 
stock) by USB (except by conversion into or exchange for stock of USB ranking 
junior to the USB 8 1/8% Preferred Stock as to dividends and upon 
liquidation) unless, in each case, the full cumulative dividends on the USB 8 
1/8% Preferred Stock shall have been paid or declared and set aside for 
payment.  Holders of shares of the USB 8 1/8% Preferred Stock shall not be 
entitled to any dividend, whether payable in cash, property or stock, in 
excess of the full dividends on such shares.  No interest shall be payable in 
respect of any dividend payment which may be in arrears on the USB 8 1/8% 
Preferred Stock.

   Dividends payable on shares of the USB 8 1/8% Preferred Stock (i) for any 
period other than a full dividend period, shall be computed on the basis of a 
360-day year consisting of twelve 30-day months and (ii) for each full 
dividend period, shall be computed by dividing the annual dividend rate by 
four.  Any dividend payment made on shares of the USB 8 1/8% Preferred Stock 
shall first be credited against the earlier accrued but unpaid dividend due 
with respect to shares of such series which remains payable.

   REDEMPTION.  The USB 8 1/8% Preferred Stock is redeemable, in whole or in 
part, from time to time at the option of USB upon not less than 30 nor more 
than 60 days' notice at $25.00 per share plus all accrued and unpaid 
dividends to the date of redemption.

   If less than all the outstanding shares of USB 8 1/8% Preferred Stock are 
to be redeemed, USB will select those to be redeemed pro rata, by lot or by a 
substantially equivalent method.  On and after the redemption date, dividends 
will cease to accrue on the shares, and they shall be deemed to cease to be 
outstanding, provided that the redemption price (including any accrued and 
unpaid dividends to the date fixed for redemption) has been duly paid or 
provided for.

   The USB 8 1/8% Preferred Stock will not be entitled to the benefits of any
sinking fund.

   Notwithstanding the foregoing, unless the full cumulative dividends on all
outstanding shares of USB 8 1/8% Preferred Stock shall have been paid or
contemporaneously are declared and paid for all past

                                      68

<PAGE>

dividend periods, no shares of USB 8 1/8% Preferred Stock shall be redeemed 
unless all outstanding shares of USB 8 1/8% Preferred Stock are 
simultaneously redeemed; provided, however that the foregoing shall not 
prevent the purchase or acquisition of shares of USB 8 1/8% Preferred Stock 
or of shares of such other series of preferred stock pursuant to a purchase 
or exchange offer made on the same terms to holders of all outstanding shares 
of USB 8 1/8% Preferred Stock, and, unless the full cumulative dividends on 
all outstanding shares of USB 8 1/8% Preferred Stock and any other stock of 
USB ranking on a parity with such series as to dividends and upon liquidation 
shall have been paid or contemporaneously are declared and paid for all past 
dividend periods, USB shall not purchase or otherwise acquire directly or 
indirectly any shares of preferred stock of such series (except by conversion 
into or exchange for stock of USB ranking junior to the preferred stock of 
such series as to dividends and upon liquidation).  In addition, in order to 
qualify as Tier 1 capital, USB 8 1/8% Preferred Stock may not be redeemed at 
USB's option without the prior approval of the Federal Reserve Board.

   LIQUIDATION PREFERENCE.  Upon any voluntary or involuntary liquidation, 
dissolution or winding up of the affairs of USB, the holders of the USB 
8 1/8% Preferred Stock will be entitled, subject to the rights of creditors, 
but before any distribution or payment to the holders of USB Common Stock or 
any other security ranking junior to the USB 8 1/8% Preferred Stock on 
liquidation, dissolution or winding up of USB, to receive $25.00 per share 
plus accrued and unpaid dividends.  In the event that, upon any such 
voluntary or involuntary liquidation, dissolution or winding up, the 
available assets of USB are insufficient to pay such amount on all 
outstanding shares of USB 8 1/8% Preferred Stock and the corresponding 
amounts payable on all shares of other classes or series of stock of USB 
ranking on a parity with the USB 8 1/8% Preferred Stock in the distribution 
of assets, then the holders of the USB 8 1/8% Preferred Stock and of all 
other such classes or series shall share ratably in any distribution of 
assets in proportion to the full amounts to which they would otherwise be 
respectively entitled.

   For such purposes, the consolidation or merger of USB with any other 
corporation shall not be deemed to constitute a liquidation, dissolution or 
winding up of USB.

   VOTING RIGHTS.  Except as otherwise noted or as required by law, each holder
of shares of USB 8 1/8% Preferred Stock shall be entitled to notice of
shareholders' meetings, but will not be entitled to vote.  When holders of USB 
8 1/8% Preferred Stock are entitled to vote, each holder, as of the record date
in connection with such vote, is entitled to one vote.

   If at any time the equivalent of six quarterly dividends, whether or not 
consecutive, payable on the USB 8 1/8% Preferred Stock are unpaid or not 
declared and set aside for payment, the number of directors of USB shall be 
increased by two and the holders of shares of the USB 8 1/8% Preferred Stock 
outstanding at the time (voting separately, as a single class, with the 
holders of shares of any one or more series of preferred stock of USB ranking 
on a parity with the USB 8 1/8% Preferred Stock as to dividends or upon 
liquidation and upon which like voting rights have been conferred and are 
exercisable) shall have the right to elect two directors to serve as such 
until all arrearages of dividends on the USB 8 1/8% Preferred Stock have been 
paid or declared and set aside for payment at which time the terms of office 
of the two directors so elected shall terminate and the number of directors 
of USB shall be reduced by two (subject to any additional rights as to the 
election of directors provided for the holders of shares of other preferred 
stock of USB).  Any director so elected may be removed by, and shall not be 
removed except by, the vote of the holders of shares of the USB 8 1/8% 
Preferred Stock outstanding at the time (voting separately as a single class 
with the holders of shares of any one or more series of preferred stock of 
USB ranking on a parity with the USB 8 1/8% Preferred Stock as to dividends 
or upon liquidation and upon which like voting rights have been conferred and 
are exercisable).

   So long as any shares of the USB 8 1/8% Preferred Stock remain outstanding,
USB shall not, without the affirmative vote or consent of the holders of at
least two-thirds of the shares of the USB 8 1/8% Preferred Stock and of any
other similarly affected series of preferred stock of USB ranking on a parity
with the USB 8 1/8% Preferred Stock as to dividends or upon liquidation and upon
which like voting rights have been conferred and are exercisable outstanding at
the time (voting separately as a single class

                                      69

<PAGE>

without regard to series), given in person or by proxy, either in writing or 
at a meeting, (i) authorize, create or issue, or increase the authorized or 
issued amount of, any class or series of stock ranking prior to the USB 8 
1/8% Preferred Stock as to dividends or upon liquidation or (ii) amend, alter 
or repeal, whether by merger or otherwise, the provisions of the USB 
Certificate so as to materially and adversely affect any of the preferences, 
limitations, and relative rights of the USB 8 1/8% Preferred Stock; provided, 
however, that any increase in the amount of the authorized preferred stock of 
USB or the creation and issuance of other series of preferred stock of USB, 
in each case ranking on a parity with or junior to the USB 8 1/8% Preferred 
Stock as to dividends or upon liquidation, will not be deemed to materially 
and adversely affect such preferences, limitations and relative rights.

   CONVERSION RIGHTS.  The USB 8 1/8% Preferred Stock is not convertible into
shares of any other class or series of the capital stock of USB.

   NO OTHER RIGHTS.  The shares of USB 8 1/8% Preferred Stock shall not have
any preferences, voting powers or relative, participating, optional or other
special rights except as set forth above, in the USB Certificate or as otherwise
required by law.

   USB SERIES 1990A PREFERRED STOCK

   In connection with the sale by USB of 12,600,000 shares of USB Common Stock
and accompanying periodic stock purchase rights and risk event warrants in a
private placement in July 1990, USB may under certain circumstances be obligated
to issue up to 12,750 shares of its Series 1990A Preferred Stock.  See 
"--Common Stock--Periodic Stock Purchase Rights and Risk Event Warrants" below. 
The shares of Series 1990A Preferred Stock would, if issued, provide for a
liquidation preference of $100,000 per share.  The dividend rate would be
adjusted quarterly and would be determined at the time of issuance.

   If, at the time of any annual meeting of USB Shareholders for the election
of directors, the amount of accrued but unpaid dividends on the Series 1990A
Preferred Stock were equal to at least six quarterly dividends on such series,
then the number of directors of USB would be increased by one and the holders of
such Series 1990A Preferred Stock, voting as a separate class, would be entitled
to elect one additional director who would continue to serve the full term for
which he or she would have been elected, notwithstanding the declaration or
payment of any dividends on the Series 1990A Preferred Stock.  The affirmative
vote or consent of the holders of at least two-thirds of the outstanding shares
of USB Series 1990A Preferred Stock will be required for any amendment of the
USB Certificate (including any certificate of designation or any similar
document relating to any series of preferred stock of USB) which will adversely
affect the powers, preferences, privileges or rights of the USB Series 1990A
Preferred Stock.  The affirmative vote or consent of the holders of at least
two-thirds of the outstanding shares of USB Series 1990A Preferred Stock will be
required to issue, authorize, or increase the authorized amount of, or issue or
authorize any obligation or security convertible into or evidencing a right to
purchase, any additional class or series of stock ranking prior to the USB
Series 1990A Preferred Stock as to dividends or upon liquidation.

   ADDITIONAL PROVISIONS.  The rights of holders of USB Common Stock will be
subject to, and may be adversely affected by, the rights of holders of any
preferred stock that may be issued in the future.  Any such issuance may
adversely affect the interests of holders of the USB Common Stock by limiting
the control that such holders may exert by exercise of their voting rights, by
subordinating their rights in liquidation to the rights of the holders of
preferred stock of USB and otherwise.  In addition, the issuance of shares of
preferred stock of USB may, in some circumstances, deter or discourage takeover
attempts and other changes in control of USB, including takeovers and changes in
control that some holders of the USB Common Stock may deem to be in their best
interests and in the best interests of USB, by making it more difficult for a
person who has gained a substantial equity interest in USB to obtain voting
control or to

                                      70
<PAGE>

exercise control effectively.  USB has no current plans or agreements with 
respect to the issuance of any other shares of preferred stock, except as 
described above with respect to the Series 1990A Preferred Stock.

COMMON STOCK

   GENERAL.  Each share of USB Common Stock is entitled to such dividends as 
may from time to time be declared by the USB Board from any funds legally 
available for dividends.  USB may not declare any cash dividends on, or make 
any payment on account of, the purchase, redemption or other retirement of, 
USB Common Stock unless full dividends (including accumulated dividends, if 
applicable) have been paid or declared or set apart for payment upon all 
outstanding shares of the preferred stock of USB and USB is not in default or 
in arrears with respect to any sinking or other analogous fund or other 
agreement for the purchase, redemption or other retirement of any shares of 
preferred stock of USB.  Holders of USB Common Stock are entitled to one vote 
per share. Shareholders do not have the right to cumulate their votes in the 
election of directors.  USB Common Stock has no conversion rights and the 
holders of USB Common Stock have no preemptive or other rights to subscribe 
for additional securities of USB.  In the event of the liquidation of USB, 
after the payment or provision for payment of all debts and liabilities and 
subject to the rights of the holders of preferred stock of USB which may be 
outstanding, the holders of USB Common Stock will be entitled to share 
ratably in the remaining assets of USB.  The USB Common Stock is listed on 
the NYSE.

   USB DIVIDEND REINVESTMENT AND COMMON STOCK PURCHASE PLAN.  Pursuant to its
USB Reinvestment and Purchase Plan, USB provides eligible shareholders with a
method of investing cash dividends and optional cash payments at 100% of the
average price (as defined in the USB Reinvestment and Purchase Plan) in
additional shares of USB Common Stock without payment of any brokerage
commission or service charge.  The USB Reinvestment and Purchase Plan includes
certain dollar limitations on participation and provides for eligible
shareholders to elect dividend reinvestment on only a part of the shares
registered in the name of a participant (while continuing to receive cash
dividends on remaining shares).  It is anticipated that the USB Reinvestment and
Purchase Plan will continue after the Effective Date and that shareholders of
Zappco who receive shares of USB Common Stock pursuant to the Merger will have
the right to participate therein.

   PERIODIC STOCK PURCHASE RIGHTS AND RISK EVENT WARRANTS.  USB has entered
into (i) a Stock Purchase Agreement, dated as of May 30, 1990 (as amended, the
"Stock Purchase Agreement"), by and among Corporate Partners, L.P. ("Corporate
Partners"), Corporate Offshore Partners, L.P. ("Offshore" and, together with
Corporate Partners, the "Partnerships"), The State Board of Administration of
Florida ("State Board") solely in its capacity as a managed account and not in
its individual capacity (State Board and the Partnerships being referred to
herein collectively as the "Purchasers"), Corporate Advisors, L.P. and USB and
(ii) a Stock Purchase Agreement, dated as of May 30, 1990 (the "Florida Stock
Purchase Agreement"), by and between State Board in its individual capacity and
USB.  Pursuant to the Stock Purchase Agreement, USB sold (a) to Corporate
Partners 8,856,241 shares of USB Common Stock, 10 Periodic Stock Purchase Rights
(each a "PSPR") and one Risk Event Warrant, (b) to Offshore 643,976 shares of
USB Common Stock, 10 PSPRs and one Risk Event Warrant and (c) to State Board
939,783 shares of USB Common Stock, 10 PSPRs and one Risk Event Warrant. 
Pursuant to the Florida Stock Purchase Agreement, USB sold to State Board
2,160,000 shares of USB Common Stock, 10 PSPRs and one Risk Event Warrant.

   The Stock Purchase Agreement and the Florida Stock Purchase Agreement 
contain transfer restrictions with respect to the shares of USB Common Stock 
acquired thereunder and standstill provisions limiting further acquisitions 
of USB Common Stock by the Purchasers and State Board.  The Stock Purchase 
Agreement and the Florida Stock Purchase Agreement also grant each of the 
Purchasers and State Board the right to purchase its pro rata share of any 
Voting Securities (as defined in the Stock Purchase Agreement) sold by USB 
for cash, subject to certain exceptions.  Pursuant to the Stock Purchase 
Agreement, the Purchasers have designated one person to act as a non-voting 
observer of the USB Board.

                                      71

<PAGE>

   Each PSPR issued to the Purchasers and State Board relates to a specific
twelve-month period commencing with the twelve-month period following closing of
the transactions contemplated under the Stock Purchase Agreement and the Florida
Stock Purchase Agreement.  Each PSPR shall become exercisable in the event that
a Dividend Shortfall (as defined in the Stock Purchase Agreement) exists for the
specific twelve-month period to which such PSPR relates.  A Dividend Shortfall
will be deemed to exist to the extent that USB has not paid a cash dividend
equal to $0.205 per share of USB Common Stock for each quarter within such
twelve-month period.  The PSPRs will be exercisable for that number of shares of
USB Common Stock or (subject to the prior approval of the Federal Reserve Board)
depositary shares representing one one-thousandth of a share of Series 1990A
Preferred Stock ("Depositary Shares") such that the holders of PSPRs will
receive value equal to the Dividend Shortfall.  Once a PSPR has become
exercisable, it will remain exercisable for a one-year period at an exercise
price of $1.25 per share of USB Common Stock or $1.00 per Depositary Share.  If
a PSPR were to become exercisable and were not redeemed by USB as described
below, the issuance of Depositary Shares or USB Common Stock upon exercise of a
PSPR could adversely affect the market price of the USB Common Stock.  If the
PSPRs were to be exercised for USB Common Stock, there could be substantial
dilution of the USB Common Stock.

   Each Risk Event Warrant will become exercisable in the event of certain 
defined change of control events with respect to USB where the value received 
by holders of the USB Common Stock is less than $13.875 per share, or in 
certain circumstances in the event the USB Common Stock is valued at less 
than $13.875 per share on the tenth anniversary of the closing of the 
transactions contemplated under the Stock Purchase Agreement.  The Risk Event 
Warrants will be exercisable for that number of shares of USB Common Stock at 
an exercise price of $1.25 per share or, in certain circumstances (subject to 
the prior approval of the Federal Reserve Board), Depositary Shares such that 
the holders of Risk Event Warrants will receive value equal to such 
shortfall.  If the Risk Event Warrants were to become exercisable and were 
not redeemed by USB as described below, the issuance of Depositary Shares or 
USB Common Stock upon exercise of a Risk Event Warrant could adversely affect 
the market price of the USB Common Stock.  If the Risk Event Warrants were to 
be exercised for USB Common Stock, there could be substantial dilution of the 
USB Common Stock.  In the event of a change in control at a time when the 
market price of the USB Common Stock is less than $13.875 per share, the Risk 
Event Warrants may have the effect of reducing the price per share to be 
received by the holders of the USB Common Stock.

   In the event of the exercise of a Risk Event Warrant upon the occurrence 
of certain change of control events, USB may, at its option (subject to the 
prior approval of the Federal Reserve Board), elect to have such Risk Event 
Warrant become exercisable for other securities of USB acceptable to the 
holder of such Risk Event Warrant in lieu of the shares of USB Common Stock 
for which such Risk Event Warrant would otherwise become exercisable.  In 
addition, USB has the right (subject to the prior approval of the Federal 
Reserve Board) to redeem any PSPR at a price equal to the Dividend Shortfall 
and any Risk Event Warrant at a price equal to the Value Shortfall (as 
defined in the Stock Purchase Agreement) or the Termination Shortfall Amount 
(as defined in the Stock Purchase Agreement), as applicable, after such PSPR 
or Risk Event Warrant, as the case may be, shall have become exercisable.  
USB also has entered into a registration rights agreement with the Purchasers 
and with State Board pursuant to which the Purchasers and State Board, 
respectively, are granted certain rights to cause USB to register with the 
Commission the USB Common Stock acquired pursuant to the Stock Purchase 
Agreement and the Florida Stock Purchase Agreement and the securities 
acquired upon exercise of the PSPRs and the Risk Event Warrants.

   The foregoing is a summary of the transactions contemplated by the Stock
Purchase Agreement and the Florida Stock Purchase Agreement and related
documents and is qualified in its entirety by the more detailed information
contained in such agreements and documents, copies of which are incorporated by
reference as exhibits to the Registration Statement of which this Proxy
Statement/Prospectus is a part.

CERTAIN PROVISIONS OF THE USB CERTIFICATE AND USB BYLAWS

   The USB Certificate requires the affirmative vote of the holders of 80% of
the "Voting Stock" (defined therein) of USB to approve certain mergers,
consolidations, reclassifications, dispositions of assets

                                      72

or liquidation, involving or proposed by certain significant shareholders, 
unless certain price and procedural requirements are met or unless the 
transaction is approved by the "Continuing Directors" (defined therein).  In 
addition, the USB Certificate provides for classification of the USB Board 
into three separate classes, sets a maximum board size of 30 and authorizes 
action by the shareholders of USB only pursuant to a meeting and not by a 
written consent.  The foregoing provisions of the USB Certificate can only be 
amended by the affirmative vote of the holders of not less than 80% of the 
outstanding USB voting stock, except with respect to any amendment to the USB 
Certificate to reduce the maximum number of USB directors to the greater of 
(i) the number of directors then in office and (ii) 24, which amendment would 
require the approval of the holders of a majority of the outstanding of USB 
Common Stock pursuant to Delaware Law.  The USB Bylaws provide that special 
meetings of shareholders may be called only by the USB Board or the chief 
executive officer.  The overall effect of these provisions may be to delay or 
prevent attempts by other corporations or groups to acquire control of USB 
without negotiation with the USB Board.

                         DESCRIPTION OF ZAPPCO CAPITAL STOCK

   The following description of the capital stock of Zappco does not purport to
be complete and is subject, in all respects, to applicable Minnesota law and to
the provisions of the Zappco Articles.  The following description is qualified
by reference to the Zappco Articles, a copy of which is included as an exhibit
to the Registration Statement of which this Proxy Statement/Prospectus is a
part.

GENERAL

   The authorized capital stock of Zappco consists of  25,000 shares of Zappco
Common Stock, par value $1.00 per share, and 10,000 shares of Preferred Stock,
par value $100 per share.  As of the Record Date, 15,842 shares of Zappco Common
Stock and no shares of Preferred Stock were issued and outstanding.  The Zappco
Board of Directors has the right, from any unissued Preferred Stock, to
designate a series and to fix the dividend rate, the redemption price, the
liquidation price, the conversion rights and the sinking or purchase fund rights
of shares of any class, or any series of any class, or the number of shares
constituting the series of any class.  

   Each share of Zappco Common Stock is entitled to receive, when, as and if
declared by the Zappco Board of Directors, out of earnings or surplus legally
available therefore, dividends payable either in cash, in property or in shares
of capital stock of Zappco, provided that all dividends due and owing to any
holders of Preferred Stock have been paid.  Holders of Common Stock are entitled
to one vote per share.  No shareholders have the right to cumulate their votes
in the election of directors, and no shareholders have preemptive rights or
other rights to subscribe for additional securities of Zappco.


                       ADJOURNMENT OF THE SPECIAL MEETING
                                (Proposal No. 3)

   In the event that there are not sufficient votes to approve the Merger
Agreement at the time of the Special Meeting, such proposal could not be
approved unless the Special Meeting were adjourned in order to permit further
solicitation of proxies from Zappco shareholders.  In order to allow proxies
that have been received by Zappco at the time of the Special Meeting to be voted
for such adjournment, if necessary, Zappco is submitting the question of
adjournment under such circumstances to its shareholders as a separate matter
for their consideration.  A majority of the shares represented in person or by
proxy and voting at the Special Meeting is required to approve any adjournment,
even if such number of shares is less than a quorum.  THE BOARD OF DIRECTORS OF
ZAPPCO RECOMMENDS THAT ZAPPCO SHAREHOLDERS VOTE FOR THE PROPOSAL TO ADJOURN THE
SPECIAL MEETING IF NECESSARY TO PERMIT FURTHER SOLICITATION OF PROXIES.

                         INDEPENDENT AUDITOR'S REPORT



Board of Directors
Zappco, Inc. And Subsidiaries
St. Cloud, Minnesota


We have audited the accompanying consolidated balance sheets of Zappco, Inc. 
And Subsidiaries as of December 31, 1996 and 1995, and the related 
consolidated statements of income, stockholders' equity and cash flows for 
the years then ended. These consolidated financial statements are the 
responsibility of the Company's management. Our responsibility is to express 
an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the consolidated financial 
statements are free of material misstatement. An audit includes examining, on 
a test basis, evidence supporting the amounts and disclosures in the 
consolidated financial statements. An audit also includes assessing the 
accounting principles used and significant estimates made by Management, as 
well as evaluating the overall consolidated financial statement presentation. 
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of Zappco, 
Inc. And Subsidiaries as of December 31, 1996 and 1995, and the results of 
their operations and their cash flows for the years then ended in conformity 
with generally accepted accounting principles.

NOTE 1    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

          DESCRIPTION OF BUSINESS

          Zappco, Inc. (Company), through its operating subsidiaries, is 
          primarily engaged in commercial banking and related services and 
          grants commercial, residential, consumer and agricultural loans to 
          customers throughout the Central Minnesota area.

          PRINCIPLES OF CONSOLIDATION

          The accompanying consolidated financial statements include the 
          accounts of the Company and its subsidiaries, Zapp Bank, N.A., 
          (wholly owned) First National Bank of Little Falls (96% owned), 
          Melrose State Bank (wholly owned), Zapp Data, Inc., a wholly owned 
          data processing service bureau, and Zapp Bank Plaza Partnership #1 
          (98.8% owned by Zappco, Inc. and 1.2% owned by Zapp Data, Inc.).

          The First National Bank of Little Falls (Little Falls) has been 
          reflected as a wholly owned subsidiary of the Company in the 
          consolidated financial statements because the Company has 
          agreements which provide that the Company has first option to 
          repurchase these shares at minimal cost from the three directors 
          of Little Falls who own the remaining 4% of outstanding stock.  In 
          addition, the rights to all dividends have been assigned to the 
          Company.

          Significant intercompany balances and transactions have been 
          eliminated from the consolidated financial statements.

          USE OF ESTIMATES

          The preparation of financial statements in conformity with 
          generally accepted accounting principles requires management to 
          make estimates and assumptions that affect the reported amounts of 
          assets and liabilities and disclosure of contingent assets and 
          liabilities at the date of the financial statements. Estimates 
          also affect the reported amounts of revenue and expense during the 
          reporting period.  Actual results could differ from those 
          estimates.

          CASH AND CASH EQUIVALENTS

          For the purpose of presentation in the statements of cash flows, 
          cash and cash equivalents are defined as those amounts included in 
          the balance sheet caption "cash and due from banks."  At times 
          these balances may be in excess of FDIC insurance limits.

          SECURITIES AVAILABLE FOR SALE

          Available for sale securities consist of bonds, notes and 
          debentures not classified as held to maturity securities.  
          Unrealized holding gains and losses, net of tax, on available for 
          sale securities are reported as a net amount in a separate 
          component of stockholders' equity until realized.  Gains and 
          losses on the sale of available for sale securities are determined 
          using the specific-identification method.  Premiums and discounts 
          are recognized in interest income using the interest method over 
          the period to maturity.  


                                     F-12
<PAGE>

NOTE 1    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

          SECURITIES HELD TO MATURITY

          Held to maturity securities consist of bonds, notes, debentures 
          and equity securities for which the subsidiary banks have the 
          positive intent and ability to hold to maturity.  Held to maturity 
          securities are reported at cost, adjusted for premiums and 
          discounts that are recognized in interest income using the 
          interest method over the period to maturity.

          LOANS

          Loans are stated at the amount of unpaid principal, reduced by 
          unearned discount and an allowance for loan losses.  Interest on 
          loans is accrued and credited to income based on the principal 
          amount outstanding.  The accrual of interest on loans is 
          discontinued when, in the opinion of management, there is an 
          indication that the borrower may be unable to meet payments as 
          they become due.  Upon such discontinuance, all unpaid accrued 
          interest is reversed.

          ALLOWANCE FOR LOAN LOSSES

          The allowance is maintained at a level adequate to absorb probable 
          losses. Management determines the adequacy of the allowance based 
          upon reviews of individual loans and related off-balance sheet 
          commitments, recent loss experience, current economic conditions, 
          the risk characteristics of the various categories of loans and 
          other pertinent factors.  Loans deemed uncollectible are charged 
          to the allowance.  Provisions for loan losses and recoveries on 
          loans previously charged off are added to the allowance.  While 
          management uses the best information available to make its 
          evaluation, future adjustments to the allowance may be necessary 
          if there are significant changes in economic conditions.

          LAND, PREMISES AND EQUIPMENT

          Property and equipment owned are stated at cost less accumulated 
          depreciation which is computed on the straight-line and 
          accelerated methods over the estimated useful lives of the assets. 
          Accelerated depreciation did not materially exceed straight-line 
          depreciation for the years ended December 31, 1996 and 1995.  Both 
          accelerated and straight-line methods are used for income tax 
          reporting purposes.

          OTHER REAL ESTATE OWNED

          Real estate acquired by foreclosure is carried in other assets at 
          the lower of the recorded investment in the property or its fair 
          value less selling costs. Prior to foreclosure, the value of the 
          underlying loan is written down to the fair market value of the 
          real estate to be acquired by a charge to the allowance for loan 
          losses, if necessary.  Any subsequent write-downs are charged 
          against operating expenses.  Operating expenses of such 
          properties, net of related income, and gains and losses on their 
          disposition are included in other expenses.

NOTE 1    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

          COST IN EXCESS OF NET ASSETS ACQUIRED

          Cost in excess of net assets acquired resulted from the Company's 
          purchase of capital stock and partnership units of its 
          subsidiaries.  These intangible assets are being amortized over a 
          20-year period on a straight-line basis.

          INCOME TAXES

          The Company files a consolidated federal and a unitary Minnesota 
          income tax return with the subsidiaries, excluding Zapp Bank Plaza 
          Partnership which files separate federal and state partnership tax 
          returns.  The provision for income taxes is allocated on a 
          separate entity basis.

          Provisions for income taxes are based on amounts reported in the 
          statements of income (after exclusion of non-taxable income such 
          as interest on state and municipal securities) and include 
          deferred taxes on temporary differences in the recognition of 
          income and expense for tax and financial statement purposes. 
          Deferred taxes are computed using the asset and liability approach 
          as prescribed in SFAS 109, ACCOUNTING FOR INCOME TAXES.

          CHANGE IN ACCOUNTING PRINCIPLE

          Effective January 1, 1995, the Company adopted the provisions of 
          Statement of Financial Accounting Standards ("SFAS") 114, 
          ACCOUNTING BY CREDITORS FOR IMPAIRMENT OF A LOAN, as amended by 
          SFAS 118.  Generally, SFAS 114 requires creditors to establish a 
          valuation allowance when it becomes probable that all principal 
          and interest due under the contractual terms of a loan will not be 
          collected.  The impairment is measured as the difference between 
          the recorded amount of the loan and the present value of expected 
          future cash flows based on the loan's effective interest rate, 
          observable market price, or fair value for a collateral dependent 
          loan.  The adoption of these standards did not have a material 
          effect on 1995 results of operations or financial position.

          OFF BALANCE SHEET FINANCIAL INSTRUMENTS

          In the ordinary course of business the Company's subsidiary banks 
          have entered into off balance sheet financial instruments 
          consisting of commitments to extend credit, line-of-credit 
          arrangements, commitments under credit card arrangements and 
          letters of credit.  Such financial instruments are recorded in the 
          financial statements when they become payable.

NOTE 2    INVESTMENT SECURITIES (CONTINUED)

          On December 5, 1995, as a result of a one-time reassessment 
          allowed by the Financial Accounting Standards Board Special 
          Report, "A Guide to Implementation of Statement 115 on Accounting 
          for Certain Investments in Debt and Equity Securities" issued in 
          November 1995, the Company's subsidiary banks transferred 
          securities with a total net book value of $46,048,907 from the 
          held-to-maturity portfolio to the available-for-sale portfolio.

          Various derivative financial instruments were included in the 
          subsidiary banks' invested assets classified as available for sale 
          at December 31, 1995.  These derivatives are generally valued 
          based on independent pricing models. Individual derivative 
          financial instruments, however, may be difficult to price and may 
          be thinly traded.  Accordingly, they are typically subject to 
          greater market and credit risk than nonderivative financial 
          instruments.  At December 31, 1995, the market value of the banks' 
          positions in derivative financial instruments approximated 4% of 
          the banks' total invested assets.  The banks held no derivative 
          financial instruments at December 31, 1996.

          Investment securities with carrying values of approximately 
          $55,084,000 and $50,328,000 were pledged to secure public and 
          trust deposits as required or permitted by law as of December 31, 
          1996 and 1995, respectively.

          On October 31, 1995, a U.S. Treasury Bond carried in the 
          held-to-maturity portfolio of one of the Company's subsidiary 
          banks was sold in response to a tender offer.  The security was 
          sold at its amortized cost of $1,114,577.

          The securities disclosed as held to maturity as of December 31, 
          1995, were transferred to the available for sale category during 
          1996.

          The maturities of investment securities at December 31, 1996, were 
          as follows:

         The deferred provision for income taxes results from temporary

         tax and financial reporting purposes, principally depreciation and the
         provision for possible loan losses.  Deferred tax assets of 
         approximately $32,000 are included in other assets at December 31, 
         1996.

NOTE 12  COMMITMENTS AND CONTINGENT LIABILITIES

         The Company's consolidated financial statements do not reflect various
         commitments and contingent liabilities which arise in the normal course
         of business and which involve elements of credit risk, interest rate 
         risk and liquidity risk of its subsidiary banks.  These commitments and
         contingent liabilities are commitments to extend credit, line-of-credit
         arrangements, credit card arrangements, and letters of credit.  A 
         summary of the subsidiary banks' commitments and contingent liabilities
         at December 31, 1996, is as follows:

</TABLE>

          Commitments to extend credit, line-of-credit arrangements, credit 
          card arrangements, and letters of credit all include exposure to some 
          credit loss in the event of nonperformance of the customer.  The 
          subsidiary banks' procedures for credit commitments and contingent 
          liabilities are the same as those for extension of credit that are 
          recorded on the consolidated statements of condition.


NOTE 13  EMPLOYEE BENEFIT PLAN

         During 1992 the Company adopted an Employee Stock Ownership Plan 
         (ESOP) as part of the existing defined contribution plan, which covers
         substantially all employees over the age of 21 who have completed one 
         year of service, as defined. Participants are vested over a five-year 
         period.  The contribution to the Plan is determined annually by the 
         board of directors.  The Company's cash contribution to the ESOP was 
         approximately $659,300 and $435,000 for the years ended December 31, 
         1996 and 1995, respectively.  Contributions will be used to purchase 
         additional shares of the Company's stock as they become available from
         current stockholders.  The ESOP has a total of 134 shares allocated to 
         participants as of December 31, 1996.

         An ESOP participant may elect to receive the full value of his or her 
         account in whole shares of employer securities (with fractional shares
         to be paid in cash) or receive the fair market value of the employer 
         securities as of the date of the distribution in cash from the Company.
         The Company's potential repurchase obligation under this arrangement 
         was approximately $234,500 and $161,900 for the years ended 
         December 31, 1996 and 1995, respectively.

NOTE 14  RELATED PARTY TRANSACTIONS

         The Company's subsidiary banks have entered into transactions with 
         their directors, significant shareholders and their affiliates (related
         parties). Such transactions were made in the ordinary course of 
         business on substantially the same terms and conditions, including 
         interest rates and collateral, as those prevailing at the same time for
         comparable transactions with other customers, and did not, in the 
         opinion of management, involve more than normal credit risk or present 
         other unfavorable features.  The aggregate amount of loans to such 
         related parties at December 31, 1996 and 1995, was approximately 
         $4,965,000 and $5,190,000, respectively.


NOTE 15  CONCENTRATIONS OF CREDIT

         The majority of the subsidiary banks' loans and commitments have been 
         granted to customers in each bank's market area.  The majority of 
         these customers are depositors of the banks.  Investments in state and 
         municipal securities involve governmental entities, the majority of 
         which are within the State of Minnesota. The concentrations of credit 
         by type of loan are set forth in Note 3.  The distribution of 
         commitments to extend credit approximates the distribution of loans 
         outstanding.  Letters of credit were granted primarily to commercial 
         borrowers.  The Company, as a matter of policy, does not extend credit 
         to any single borrower or group of related borrowers in excess of 
         $4,324,000.


NOTE 16  REGULATORY MATTERS

         The Company has two subsidiary banks (Zapp Bank, N.A. and First 
         National Bank of Little Falls) that are national banks and one 
         subsidiary bank (Melrose State Bank) that is a state bank.

         National banks are subject to the dividend restrictions set forth by 
         the Comptroller of the Currency.  Under such restrictions, the banks 
         may not, without the prior approval of the Comptroller of the Currency,
         declare dividends in excess of the sum of the current year's earnings
         (as defined) plus the retained earnings (as defined) from the prior two
         years.  

         The state bank is subject to the dividend restrictions set forth by the
         Minnesota Department of Commerce.  Under such restrictions, the bank
         may not, without prior approval of the Minnesota Department of 
         Commerce, declare dividends in excess of the sum of 50% of the prior 
         three year's earnings (as defined) subject to other minimum capital 
         percentages and classified asset percentages.

NOTE 16  REGULATORY MATTERS (CONTINUED)

         The dividends that the Company's subsidiary banks could declare during 
         1997 without prior regulatory approval are as follows:

         Melrose State Bank                    $152,793

</TABLE>

         The subsidiary banks are also required to maintain minimum amounts of 
         capital to total "risk weighted" assets, as defined by banking 
         regulators.  At December 31, 1996, the subsidiary banks are required 
         to have minimum Tier 1 and Total capital ratios of 4.0% and 8.0%, 
         respectively.  Each bank's actual risk weighted capital ratios at that
         date were as follows:

NOTE 17  DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

         The following methods and assumptions were used to estimate the fair 
         value of each class of financial instruments for which it is 
         practicable to estimate that value:

         CASH AND DUE FROM BANKS, INTEREST-BEARING DEPOSITS IN BANKS, FEDERAL 
         FUNDS SOLD, FEDERAL FUNDS PURCHASED AND SECURITIES SOLD UNDER 
         AGREEMENTS TO REPURCHASE

         For short-term instruments, the carrying amount is a reasonable 
         estimate of fair value.

         ACCRUED INTEREST RECEIVABLE AND ACCRUED INTEREST PAYABLE

         For these short-term receivables and payables, the carrying amount is a
         reasonable estimate of fair value.

         SECURITIES AVAILABLE FOR SALE

         For securities held as investments, fair value equals quoted market 
         price, if available.  If a quoted market price is not available, fair 
         value is estimated using quoted market prices for similar securities.

<PAGE>

NOTE 17  DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

         LOANS

         The fair value of loans is estimated by discounting the future cash 
         flows using the current rates at which similar loans would be made to 
         borrowers with similar credit ratings and for the same remaining 
         maturities.

         DEPOSIT LIABILITIES 

         The fair value of demand deposits, savings accounts, and certain 
         money market deposits is the amount payable on demand at the reporting
         date.  The fair value of fixed-maturity certificates of deposit is 
         estimated using the rates currently offered for deposits of similar 
         remaining maturities.

         LONG-TERM DEBT

         Rates currently available to the Company for debt with similar terms 
         and remaining maturities are used to estimate fair value of existing 
         debt.

         COMMITMENTS TO EXTEND CREDIT, LINE-OF-CREDIT ARRANGEMENTS, CREDIT CARD
         ARRANGEMENTS, AND LETTERS OF CREDIT

         For these commitments, the carrying amount is a reasonable estimate 
         of fair value, since the stated fees and interest rates charged on 
         these arrangements does not significantly vary from the terms 
         currently being offered.

                         INDEPENDENT AUDITOR'S REPORT



Board of Directors
Zappco, Inc. And Subsidiaries
St. Cloud, Minnesota


We have audited the accompanying consolidated balance sheets of Zappco, Inc. And
Subsidiaries as of December 31, 1995 and 1994, and the related consolidated
statements of income, stockholders' equity and cash flows for the years then
ended.  These consolidated financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements.  An audit also includes assessing the accounting principles used and
significant estimates made by Management, as well as evaluating the overall
consolidated financial statement presentation.  We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Zappco, Inc. And
Subsidiaries as of December 31, 1995 and 1994, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.

As described in Note 1 to the financial statements and as required by generally
accepted accounting principles, the Company changed its method of accounting for

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1994

NOTE 1   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS
Zappco, Inc. (Company), through its operating subsidiaries, is primarily engaged
in commercial banking and related services and grants commercial, residential,
consumer and agricultural loans to customers throughout the Central Minnesota
area.

PRINCIPLES OF CONSOLIDATION
The accompanying consolidated financial statements include the accounts of the
Company and its subsidiaries, Zapp Bank, N.A., (wholly owned) First National
Bank of Little Falls (97.3% owned), Melrose State Bank (wholly owned), Zapp
Data, Inc., a wholly owned data processing service bureau, and Zapp Bank Plaza
Partnership #1 (98.8% owned by Zappco, Inc. and 1.2% owned by Zapp Data, Inc.).

Effective March 11, 1994, Melrose Bancshares, Inc., a wholly owned holding
company that owned 100% of the outstanding stock of Melrose State Bank, was
merged into Zappco, Inc.  All shares of stock of Melrose Bancshares, Inc. were
surrendered to Zappco, Inc. and canceled.  Since Zappco, Inc. was the sole
shareholder of all of the shares of stock of Melrose Bancshares, Inc., no
conversion of the shares of Melrose Bancshares, Inc. was necessary.  This merger
had no effect on 1994 earnings.

The First National Bank of Little Falls (Little Falls) has been reflected as a
wholly owned subsidiary of the Company in the consolidated financial statements
because the Company has agreements which provide that the Company has first
option to repurchase these shares at minimal cost from the two directors of
Little Falls who own the remaining 2.7% of outstanding stock.  In addition, the
rights to all dividends have been assigned to the Company.

Significant intercompany balances and transactions have been eliminated from the
consolidated financial statements.

USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements. 
Estimates also affect the reported amounts of revenue and expense during the
reporting period.  Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS
For the purpose of presentation in the statements of cash flows, cash and cash
equivalents are defined as those amounts included in the balance sheet caption
"cash and due from banks."  At times these balances may be in excess of FDIC
insurance limits.

                                      F-33

NOTE 1   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

SECURITIES AVAILABLE FOR SALE
Available for sale securities consist of bonds, notes and debentures not
classified as held to maturity securities.  Unrealized holding gains and losses,
net of tax, on available for sale securities are reported as a net amount in a
separate component of stockholders' equity until realized.  Gains and losses on
the sale of available for sale securities are determined using the
specific-identification method.  Premiums and discounts are recognized in
interest income using the interest method over the period to maturity.

SECURITIES HELD TO MATURITY
Held to maturity securities consist of bonds, notes, debentures and equity
securities for which the subsidiary banks have the positive intent and ability
to hold to maturity.  Held to maturity securities are reported at cost, adjusted
for premiums and discounts that are recognized in interest income using the
interest method over the period to maturity.

LOANS
Loans are stated at the amount of unpaid principal, reduced by unearned discount
and an allowance for loan losses.  Interest on loans is accrued and credited to
income based on the principal amount outstanding.  The accrual of interest on
loans is discontinued when, in the opinion of management, there is an indication
that the borrower may be unable to meet payments as they become due.  Upon such
discontinuance, all unpaid accrued interest is reversed.

ALLOWANCE FOR LOAN LOSSES
The allowance is maintained at a level adequate to absorb probable losses. 
Management determines the adequacy of the allowance based upon reviews of
individual loans and related off-balance sheet commitments, recent loss
experience, current economic conditions, the risk characteristics of the various
categories of loans and other pertinent factors.  Loans deemed uncollectible are
charged to the allowance.  Provisions for loan losses and recoveries on loans
previously charged off are added to the allowance.  While management uses the
best information available to make its evaluation, future adjustments to the
allowance may be necessary if there are significant changes in economic
conditions.

LAND, PREMISES AND EQUIPMENT
Property and equipment owned are stated at cost less accumulated depreciation
which is computed on the straight-line and accelerated methods over the
estimated useful lives of the assets.  Accelerated depreciation did not
materially exceed straight-line depreciation for the years ended December 31,
1995 and 1994.  Both accelerated and straight-line methods are used for income
tax reporting purposes.

NOTE 1   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

OTHER REAL ESTATE OWNED
Real estate acquired by foreclosure is carried in other assets at the lower of
the recorded investment in the property or its fair value less selling costs. 
Prior to foreclosure, the value of the underlying loan is written down to the
fair market value of the real estate to be acquired by a charge to the allowance
for loan losses, if necessary.  Any subsequent write-downs are charged against
operating expenses.  Operating expenses of such properties, net of related
income, and gains and losses on their disposition are included in other
expenses.

COST IN EXCESS OF NET ASSETS ACQUIRED
Cost in excess of net assets acquired resulted from the Company's purchase of
capital stock and partnership units of its subsidiaries.  These intangible
assets are being amortized over a 20-year period on a straight-line basis.

INCOME TAXES
The Company files a consolidated federal and a unitary Minnesota income tax
return with the subsidiaries, excluding Zapp Bank Plaza Partnership which files
separate federal and state partnership tax returns.  The provision for income
taxes is allocated on a separate entity basis.

Provisions for income taxes are based on amounts reported in the statements of
income (after exclusion of non-taxable income such as interest on state and
municipal securities) and include deferred taxes on temporary differences in the
recognition of income and expense for tax and financial statement purposes. 
Deferred taxes are computed using the asset and liability approach as prescribed
in SFAS 109, ACCOUNTING FOR INCOME TAXES.

CHANGE IN ACCOUNTING PRINCIPLE
Effective January 1, 1995, the Company adopted the provisions of Statement of
Financial Accounting Standards ("SFAS") 114, ACCOUNTING BY CREDITORS FOR
IMPAIRMENT OF A LOAN, as amended by SFAS 118.  Generally, SFAS 114 requires
creditors to establish a valuation allowance when it becomes probable that all
principal and interest due under the contractual terms of a loan will not be
collected.  The impairment is measured as the difference between the recorded
amount of the loan and the present value of expected future cash flows based on
the loan's effective interest rate, observable market price, or fair value for a
collateral dependent loan.  The adoption of these standards did not have a
material effect on 1995 results of operations or financial position.

                                      F-35

NOTE 1   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Effective January 1, 1994, the Company adopted the provisions of Statement of
Financial Accounting Standards ("SFAS") 115, ACCOUNTING FOR CERTAIN INVESTMENTS
IN DEBT AND EQUITY SECURITIES.  Generally, SFAS 115 requires that investments in
debt securities and equity securities with readily determinable fair values be
classified into three categories which then establish the accounting
requirements.  The accounting for two of the categories, trading securities and
held-to-maturity securities, is essentially the same as prior practice.  The new
category, available-for-sale securities, is accounted for at fair value with
unrealized holding gains or losses being reported in stockholders' equity.  As a
result of adopting this statement, $12,760,736 of investment securities were
reclassified as available for sale with $56,200, net of tax, being recorded as
an unrealized gain in stockholders' equity as of January 1, 1994.

OFF BALANCE SHEET FINANCIAL INSTRUMENTS
In the ordinary course of business the Company's subsidiary banks have entered
into off balance sheet financial instruments consisting of commitments to extend
credit, line-of-credit arrangements, commitments under credit card arrangements
and letters of credit.  Such financial instruments are recorded in the financial
statements when they become payable.


NOTE 2   INVESTMENT SECURITIES

Debt and equity securities have been classified in the consolidated balance
sheet according to management's intent.  The carrying amounts of investment
securities and their approximate market values at December 31, were as follows:

</TABLE>

Market value of investment securities was determined from bond portfolio reports
used by the Company.  The equity securities consist mainly of stock in the
Federal Reserve Bank, the Federal Home Loan Bank and the United Banker's Bank.

On December 5, 1995, as a result of a one-time reassessment allowed by the
Financial Accounting Standards Board Special Report, "A Guide to Implementation
of Statement 115 on Accounting for Certain Investments in Debt and Equity
Securities" issued in November 1995, the Company's subsidiary banks transferred
securities with a total net book value of $46,048,907 from the held-to-maturity
portfolio to the available-for-sale portfolio.

Various derivative financial instruments are included in the subsidiary banks'
invested assets classified as available for sale at December 31, 1995.  These
derivatives are generally valued based on independent pricing models. 
Individual derivative financial instruments, however, may be difficult to price
and may be thinly traded.  Accordingly, they are typically subject to greater
market and credit risk than nonderivative financial instruments.  At December
31, 1995, the market value of the banks' positions in derivative financial
instruments approximated 4% of the banks' total invested assets.

Investment securities with carrying values of approximately $50,328,000 and
$40,598,000 were pledged to secure public and trust deposits as required or
permitted by law as of December 31, 1995 and 1994, respectively.

NOTE 11  INCOME TAXES (CONTINUED)

The deferred provision for income taxes results from temporary differences in
the recognition of certain income and expense items for tax and financial
reporting purposes, principally depreciation and the provision for possible loan
losses.  Deferred tax liabilities of approximately $6,000 are included in other
liabilities at December 31, 1995, and deferred tax assets of approximately
$243,000 are included in other assets at December 31, 1994.


NOTE 12  COMMITMENTS AND CONTINGENT LIABILITIES

The Company's consolidated financial statements do not reflect various
commitments and contingent liabilities which arise in the normal course of
business and which involve elements of credit risk, interest rate risk and
liquidity risk of its subsidiary banks.  These commitments and contingent
liabilities are commitments to extend credit, line-of-credit arrangements,
credit card arrangements, and letters of credit.  A summary of the subsidiary
banks' commitments and contingent liabilities at December 31, 1995, is as
follows:

                                            Amount    
                                         -------------
    Commitments to Extend Credit         $  17,555,508
    Line-of-Credit Arrangements             28,847,742
    Credit Card Arrangements                10,275,080
    Letters of Credit                        5,142,872
                                         -------------
             Total                       $  61,821,202
                                         -------------
                                         -------------

Commitments to extend credit, line-of-credit arrangements, credit card
arrangements, and letters of credit all include exposure to some credit loss in
the event of nonperformance of the customer.  The subsidiary banks' procedures
for credit commitments and contingent liabilities are the same as those for
extension of credit that are recorded on the consolidated statements of
condition.

One of the Company's subsidiary banks entered into a cash management agreement
with American Bank, N.A. of St. Paul, Minnesota, during 1994.  As part of the
agreement, American Bank issued an unsecured Federal Fund Facility through which
the subsidiary bank may purchase up to $5,000,000 in Federal Funds to cover any
overdrafts that may exist in its correspondent account with American Bank, N.A.

NOTE 13  EMPLOYEE BENEFIT PLAN

During 1992 the Company adopted an Employee Stock Ownership Plan (ESOP) as part
of the existing defined contribution plan, which covers substantially all
employees over the age of 21 who have completed one year of service, as defined.
Participants are vested over a five-year period.  The annual contribution to the
Plan is determined annually by the board of directors.  The Company's cash
contribution to the ESOP was approximately $435,000 and $430,000 for the years
ended December 31, 1995 and 1994, respectively.  Contributions will be used to
purchase additional shares of the Company's stock as they become available from
current stockholders.  The ESOP has a total of 128 shares allocated to
participants as of December 31, 1995.

An ESOP participant may elect to receive the full value of his or her account in
whole shares of employer securities (with fractional shares to be paid in cash)
or receive the fair market value of the employer securities as of the date of
the distribution in cash from the Company.  The Company's potential repurchase
obligation under this arrangement was approximately $161,900 and $90,500 for the
years ended December 31, 1995 and 1994, respectively.


NOTE 14  RELATED PARTY TRANSACTIONS

The Company's subsidiary banks have entered into transactions with their
directors, significant shareholders and their affiliates (related parties). 
Such transactions were made in the ordinary course of business on substantially
the same terms and conditions, including interest rates and collateral, as those
prevailing at the same time for comparable transactions with other customers,
and did not, in the opinion of management, involve more than normal credit risk
or present other unfavorable features.  The aggregate amount of loans to such
related parties at December 31, 1995 and 1994, was approximately $5,190,000 and
$5,238,000, respectively.


NOTE 15  CONCENTRATIONS OF CREDIT

The majority of the subsidiary banks' loans and commitments have been granted to
customers in each bank's market area.  The majority of these customers are
depositors of the banks.  Investments in state and municipal securities involve
governmental entities, the majority of which are within the State of Minnesota. 
The concentrations of credit by type of loan are set forth in Note 3.  The
distribution of commitments to extend credit approximates the distribution of
loans outstanding.  Letters of credit were granted primarily to commercial
borrowers.  The Company, as a matter of policy, does not extend credit to any
single borrower or group of related borrowers in excess of $3,937,000.

NOTE 16  REGULATORY MATTERS

The Company has two subsidiary banks (Zapp Bank, N.A. and First National Bank of
Little Falls) that are national banks and one subsidiary bank (Melrose State
Bank) that is a state bank.

National banks are subject to the dividend restrictions set forth by the
Comptroller of the Currency.  Under such restrictions, the banks may not,
without the prior approval of the Comptroller of the Currency, declare dividends
in excess of the sum of the current year's earnings (as defined) plus the
retained earnings (as defined) from the prior two years.  

The state bank is subject to the dividend restrictions set forth by the
Minnesota Department of Commerce.  Under such restrictions, the bank may not,
without prior approval of the Minnesota Department of Commerce, declare
dividends in excess of 50% of the prior year's earnings (as defined) subject to
other minimum capital percentages and classified asset percentages.

The dividends that the Company's subsidiary banks could declare during 1996
without prior regulatory approval are as follows:

            Subsidiary                           Unrestricted Dividends
- --------------------------------------    -------------------------------------
Zapp Bank, N.A.                           $1,237,512 plus 1996 current earnings
First National Bank of Little Falls       $286,577 plus 1996 current earnings
Melrose State Bank                        $111,888

The subsidiary banks are also required to maintain minimum amounts of capital to
total "risk weighted" assets, as defined by banking regulators.  At December 31,
1995, the subsidiary banks are required to have minimum Tier 1 and Total capital
ratios of 4.0% and 8.0%, respectively.  Each bank's actual risk weighted capital
ratios at that date were as follows:  

                                       Tier 1 Capital    Total Capital
                                       --------------    -------------
    Zapp Bank, N.A.                         11.27%          12.61%
                                       --------------    -------------
                                       --------------    -------------
    First National Bank of Little Falls     11.31%          12.02%
                                       --------------    -------------
                                       --------------    -------------
    Melrose State Bank                      12.29%          13.54%
                                       --------------    -------------
                                       --------------    -------------

NOTE 17  DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate that
value:

CASH AND DUE FROM BANKS, INTEREST-BEARING DEPOSITS IN BANKS, FEDERAL FUNDS SOLD,
FEDERAL FUNDS PURCHASED AND SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE
For short-term instruments, the carrying amount is a reasonable estimate of fair
value.

ACCRUED INTEREST RECEIVABLE AND ACCRUED INTEREST PAYABLE
For these short-term receivables and payables, the carrying amount is a
reasonable estimate of fair value

SECURITIES AVAILABLE FOR SALE AND SECURITIES HELD TO MATURITY
For securities held as investments, fair value equals quoted market price, if
available.  If a quoted market price is not available, fair value is estimated
using quoted market prices for similar securities.

LOANS
The fair value of loans is estimated by discounting the future cash flows using
the current rates at which similar loans would be made to borrowers with similar
credit ratings and for the same remaining maturities.

DEPOSIT LIABILITIES
The fair value of demand deposits, savings accounts, and certain money market
deposits is the amount payable on demand at the reporting date.  The fair value
of fixed-maturity certificates of deposit is estimated using the rates currently
offered for deposits of similar remaining maturities.

LONG-TERM DEBT
Rates currently available to the Company for debt with similar terms and
remaining maturities are used to estimate fair value of existing debt.

COMMITMENTS TO EXTEND CREDIT, LINE-OF-CREDIT ARRANGEMENTS, CREDIT CARD
ARRANGEMENTS, AND LETTERS OF CREDIT
For these commitments, the carrying amount is a reasonable estimate of fair
value, since the stated fees and interest rates charged on these arrangements
does not significantly vary from the terms currently being offered.

                       AGREEMENT AND PLAN OF MERGER


          This AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated 
September 12, 1997, is made and entered into by and between U.S. Bancorp, a 
Delaware corporation ("Acquiror"), and Zappco, Inc., a Minnesota corporation 
("Seller").

          WHEREAS, the respective Boards of Directors of Acquiror and Seller 
have determined that it is advisable and in the best interests of Acquiror 
and Seller and their respective shareholders to consummate the merger of 
Seller with and into Acquiror as described in Article1 of this Agreement (the 
"Merger");

          WHEREAS, as a result of the Merger, all of the outstanding shares 
of the common stock, $1.00 par value, of Seller (the "Seller Common Stock"), 
will be converted into shares of the common stock, $1.25 par value, of 
Acquiror ("Acquiror Common Stock") on the terms and subject to the conditions 
set forth in this Agreement;

          WHEREAS, Seller owns (a) all of the issued and outstanding capital 
stock of each of Zapp Bank, National Association, First National Bank of 
Little Falls, and Melrose State Bank (individually, a "Bank" and, 
collectively, the "Banks"); (b) all of the issued and outstanding capital 
stock of Zapp Data, Inc. ("ZDI"); and (c) owns a 98.8% general partnership in 
Zapp Bank Plaza Partnership ("ZBPP") (the Banks, ZDI and ZBPP are hereinafter 
collectively referred to as the "Subsidiaries"); and

          WHEREAS, Acquiror and Seller desire that the Merger be made on the 
terms and subject to the conditions set forth in this Agreement and that the 
Merger qualify as a reorganization within the meaning of Section 368(a) of the 
Internal Revenue Code of 1986, as amended (the "Code").

          NOW, THEREFORE, in consideration of the representations, warranties 
and covenants contained herein, the parties hereto agree as follows:

                                   ARTICLE 1

                                    MERGER

          Subject to the satisfaction or waiver of the conditions set forth 
in Article 6, on a date mutually satisfactory to the parties as soon as 
practicable following receipt of all necessary regulatory approvals of the 
Board of Governors of the Federal Reserve System ("FRB"), Seller will merge 
with and into Acquiror.  Acquiror, in its capacity as the corporation 
surviving the Merger, is sometimes referred to herein as the "Surviving 
Corporation."  The Merger will be effected pursuant to the provisions of, and 
with the effect provided in, Section 252 of the Delaware General Corporation 
Law (the "DGCL") and Section 601 of the Minnesota Business Corporation Act 
(the "MBCA").

          1.1. EFFECT OF MERGER.

          (a)  At the Effective Time (as defined in Section1.1(d)), Seller 
shall be merged with and into Acquiror, and the separate existence of Seller 
shall cease.  The Charter (as defined in Section 2.2) and the Bylaws of 
Acquiror, as in effect immediately prior to the Effective Time, shall be the 
Charter and the Bylaws of the Surviving Corporation, until the same may be 
amended as provided therein and in accordance with applicable law.  The 
directors and officers of Acquiror immediately prior to the Effective Time 
will be the directors and officers of the Surviving Corporation, in each case 
until their respective successors are duly elected or appointed and shall 
qualify.

<PAGE>

          (b)  At the Effective Time and thereafter, the Surviving 
Corporation shall be responsible and liable for all the liabilities, debts, 
obligations and penalties of each of Acquiror and Seller.

          (c)  At the Effective Time and thereafter, the Surviving 
Corporation shall possess all the rights, privileges, immunities and 
franchises, of a public as well as of a private nature, of each of Acquiror 
and Seller; all property, real, personal and mixed, and all debts due on 
whatever account, and all and every other interest, of or belonging to or due 
to each of Acquiror and Seller, shall be taken and deemed to be transferred 
to and vested in the Surviving Corporation without further act or deed; and 
the title to any real estate or any interest therein, vested in Acquiror or 
Seller, shall not revert or be in any way impaired by reason of the Merger.

          (d)  To effect the Merger, the parties hereto will cause an 
appropriate certificate of merger and articles of merger relating to the 
Merger to be filed with the Secretary of State of Delaware and Minnesota, 
respectively. The Merger shall become effective upon the filing of such 
certificate of merger and articles of merger.  As used herein, the term 
"Effective Date" shall mean the date on which the Merger shall become 
effective as provided in the preceding sentence and the term "Effective Time" 
shall mean the time on the Effective Date when the Merger shall become 
effective.

          1.2. CONVERSION OF SELLER COMMON STOCK.  To effectuate the Merger 
and subject to the terms and conditions of this Agreement:

          (a)  At the Effective Time, each issued and outstanding share of 
Seller Common Stock (other than shares to be canceled pursuant to Section 
1.2(b) and Dissenting Shares (as defined in Section1.8))(the "Converted 
Shares") shall be converted into such number of shares of Acquiror Common 
Stock as shall be determined in accordance with the following sentence, all 
subject to adjustment as provided in Section 1.4.  The number of shares of 
Acquiror Common Stock into which each Converted Share shall convert 
(hereinafter the "Exchange Rate") shall be determined in accordance with the 
following formula:

          Exchange Rate = (X DIVIDED BY Y) DIVIDED BY Z

          Where:

          X   =   $68 million (the "Purchase Price"), adjusted as provided in
                  Section 1.3;

          Y   =   the average of the closing prices of Acquiror Common Stock
                  as quoted on the New York Stock Exchange for the ten 
                  consecutive trading days ending with the day preceding the 
                  Effective Date (the "Average Closing Price"); and

          Z   =   the number of shares of Seller Common Stock outstanding
                  immediately prior to the Effective Time.

          (b)  Each share of Seller Common Stock held as treasury stock of 
Seller or held directly or indirectly by Acquiror, other than shares held in 
a fiduciary capacity or in satisfaction of a debt previously contracted, 
shall be canceled, retired and cease to exist, and no exchange or payment 
shall be made with respect thereto.

          1.3. ADJUSTMENTS TO PURCHASE PRICE.


                                     A-2
<PAGE>

          (a)  On a date that is five business days prior to the Effective 
Date, Seller shall deliver to Acquiror a balance sheet of Seller dated as of 
the last day of the month immediately preceding the Effective Date (the 
"Final Balance Sheet").  The Purchase Price shall be (x) increased by the 
amount, if any, by which  the Final Retained Earnings (as defined below) 
exceeds $22,596,472 and (y) decreased by the amount, if any, by which Final 
Retained Earnings is less than $22,596,472. Acquiror and Seller shall 
cooperate and promptly commence good faith negotiations to resolve any 
disputes regarding the Final Balance Sheet. The "Final Retained Earnings" 
shall be equal to the amount of Seller's retained earnings (referred to 
therein as "undivided profits") as reflected on the Final Balance Sheet 
(which Final Balance Sheet shall be as mutually agreed to by Seller and 
Acquiror) plus an amount equal to the product of (x) the Average Daily 
Retained Earnings (as defined below) times (y) the number of days from but 
excluding the date of the Final Balance Sheet to and including the Effective 
Date.  The "Average Daily Retained Earnings" shall be equal to the quotient 
derived by calculating the difference between retained earnings as reflected 
on the Final Balance Sheet and $22,596,472 and dividing that difference (if 
positive) by the number of calendar days in the period from but excluding 
December 31, 1996 to and including the date of Final Balance Sheet.

          (b)   In determining the Final Retained Earnings and the Average 
Daily Retained Earnings, Seller shall prepare the Final Balance Sheet in 
accordance with the accounting methods and practices used by Seller in 
preparing the Seller Financial Statements (as defined in Section 3.4), except 
that in no event will any gains on sale of assets not in the ordinary course 
of business or other extraordinary or unusual items be included in 
determining the Final Retained Earnings.  Without limiting the generality of 
the foregoing, Seller shall continue to make provision for loan losses and 
other reserves on the balance sheets of the Banks in a manner consistent with 
past practices, and Seller shall not alter or vary its practices and policies 
relating to classified loans and loan write-offs.  

          1.4. ADDITIONAL ACQUIROR COMMON STOCK; ADJUSTMENTS.   If, between 
the date hereof and the Effective Time, shares of Acquiror Common Stock shall 
be changed into a different number of shares or a different class of shares 
by reason of any reclassification, recapitalization, split-up, combination, 
exchange of shares or readjustment, or if a stock dividend thereon shall be 
declared with a record date within such period, then the number of shares of 
Acquiror Common Stock issued to holders of Converted Shares at the Effective 
Time pursuant to this Agreement will be appropriately and proportionately 
adjusted so that the number of such shares of Acquiror Common Stock (or such 
class of shares into which shares of Acquiror Common Stock have been changed) 
that will be issued in exchange for the Converted Shares will equal the 
number of such shares that the holders of Converted Shares would have 
received pursuant to such classification, recapitalization, split-up, 
combination, exchange of shares or readjustment had the record date therefor 
been immediately following the Effective Time.  

          1.5. RIGHTS OF HOLDERS OF SELLER COMMON STOCK; CAPITAL STOCK OF 
ACQUIROR.

          (a)  At and after the Effective Time and until surrendered for 
exchange, each outstanding stock certificate which immediately prior to the 
Effective Time represented the Converted Shares shall be deemed for all 
purposes to evidence ownership of and to represent the number of whole shares 
of Acquiror Common Stock into which such Converted Shares shall have been 
converted, and the record holder of such outstanding stock certificate shall, 
after the Effective Time, be entitled to vote the shares of Acquiror Common 
Stock into which such shares of Seller Common Stock shall have been converted 
on any matters on which the holders of record of Acquiror Common Stock, as of 
any date subsequent to the Effective Time, shall be entitled to vote.  In any 
matters relating to such stock certificates, Acquiror may rely conclusively 
upon the record of shareholders maintained by Seller containing the names and 
addresses of the holders of record of Seller Common Stock at the Effective 
Time.

                                     A-3
<PAGE>

          (b)  At and after the Effective Time, each share of capital stock 
of Acquiror issued and outstanding immediately prior to the Effective Time 
shall remain an issued and existing share of capital stock of the Surviving 
Corporation and shall not be affected by the Merger.

          1.6. NO FRACTIONAL SHARES. No fractional shares of Acquiror Common 
Stock, and no certificates representing any fractional shares, shall be 
issued upon the surrender for exchange of certificates representing Seller 
Common Stock nor in connection with the shares of Acquiror Common Stock to be 
received, if any, pursuant to Section 1.4.  In lieu of any fractional share, 
Acquiror shall pay to each holder of Seller Common Stock who otherwise would 
be entitled to receive a fractional share of Acquiror Common Stock an amount 
of cash (without interest) equal to the product of (a) the Average Closing 
Price multiplied by (b) the fractional share interest to which such holder 
would otherwise be entitled.

          1.7. EXCHANGE OF CERTIFICATES.

          (a)  PAYMENT OF MERGER CONSIDERATION; EXCHANGE OF CERTIFICATES.  At 
the Effective Time, each holder of a Converted Share may surrender such 
certificate or certificates to Acquiror to effect the exchange of such 
certificate or certificates on such holder's behalf.  After surrender to 
Acquiror of any certificate which prior to the Effective Date represented a 
Converted Share, Acquiror shall distribute to the person in whose name such 
certificate is registered, a certificate or certificates representing the 
number of whole shares of Acquiror Common Stock issuable to such holder under 
Section 1.2(a)(i) plus cash payments in lieu of fractional shares, if any, as 
provided in Section 1.6 (the "Merger Consideration"); provided, however, that 
certificates surrendered for exchange by any person deemed an "affiliate" of 
Seller (as defined in Section 5.14) or otherwise designated by Acquiror as 
provided in Section 5.14 shall not be exchanged for the Merger Consideration 
until Acquiror has received a written agreement from such person as provided 
in Section 5.14.

          (b)  FAILURE TO SURRENDER CERTIFICATES.  If outstanding 
certificates formerly representing Converted Shares are not surrendered prior 
to the date on which the Merger Consideration to which any holder of such 
shares is entitled as a result of the Merger would otherwise escheat to or 
become the property of any governmental unit or agency, the unclaimed 
consideration shall, to the extent permitted by abandoned property and any 
other applicable law, become the property of Acquiror (and to the extent not 
in Acquiror's possession shall be paid over to Acquiror), free and clear of 
any and all claims or interest of any person.  Notwithstanding the foregoing, 
neither Acquiror nor any other person shall be liable to any former holder of 
Seller Common Stock for any amount delivered to a public official pursuant to 
applicable abandoned property, escheat or other similar laws.

          (c)  LOST CERTIFICATES.  In the event that any certificate 
representing Seller Common Stock shall have been lost, stolen or destroyed, 
Acquiror shall pay in exchange for such lost, stolen or destroyed 
certificate, upon the making of an affidavit of that fact by the holder 
thereof in form satisfactory to Acquiror, the Merger Consideration; provided, 
however, that Acquiror may, in its sole discretion and as a condition 
precedent to the issuance and payment of the Merger Consideration to which 
the holder of such certificate is entitled as a result of the Merger, require 
the owner of such lost, stolen or destroyed certificate to deliver a bond in 
such sum as it may direct as indemnity against any claim that may be made 
against Acquiror, Seller or any other party with respect to the certificate 
alleged to have been lost, stolen or destroyed.

          (d)  DIVIDENDS.  Until outstanding certificates formerly 
representing Converted Shares are surrendered as provided in Section 1.7(a), 
no dividend or distribution payable to holders of record of Acquiror Common 
Stock shall be paid to any holder of such outstanding certificates, but upon 
surrender of such outstanding certificates by such holder there shall be paid 
to such holder the amount 

                                     A-4
<PAGE>

of any dividends or distributions (without interest) theretofore paid with 
respect to such whole shares of Acquiror Common Stock, but not paid to such 
holder, and which dividends or distributions had a record date occurring on 
or subsequent to the Effective Time.

          (e)  FULL SATISFACTION.  All Merger Consideration issued and paid 
upon the surrender for exchange of Converted Shares in accordance with the 
terms and conditions of this Agreement shall be deemed to have been issued 
and paid in full satisfaction of all rights pertaining to such Converted 
Shares.

          1.8. DISSENTING SHARES.

          (a)  Notwithstanding any provision of this Agreement to the 
contrary, any shares of Seller Common Stock held by a holder (a "Dissenting 
Shareholder") who has demanded and perfected his demand for appraisal of his 
Shares in accordance with Sections 471 and 473 of the MBCA and as of the 
Effective Time has neither effectively withdrawn nor lost his right to such 
appraisal shall not represent a right to receive shares of Acquiror Common 
Stock pursuant to Section 1.2 above, but in lieu thereof the holder thereof 
shall be entitled to only such rights as are granted by the MBCA.  Acquiror 
shall make any and all payments to holders of shares of Seller Common Stock 
with respect to such demands.

          (b)  Notwithstanding the provisions of Section 1.8(a) above, if any 
Dissenting Shareholder demanding appraisal of such Dissenting Shareholder's 
shares of Seller Common Stock ("Dissenting Shares") under the MBCA shall 
effectively withdraw or lose (through failure to perfect or otherwise) his 
right to appraisal, then as of the Effective Time or the occurrence of such 
event, whichever later occurs, such Dissenting Shares shall automatically be 
converted into and represent only the right to receive the Merger 
Consideration as provided in Section 1.2 above upon surrender of the 
certificate or certificates representing such Dissenting Shares.

          (c)  Seller shall give Acquiror prompt notice of any demands by a 
Dissenting Shareholder for payment, or notices of intent to demand payment 
received by Seller under Sections 473 of the MBCA and Acquiror shall have the 
right to participate in all negotiations and proceedings with respect to such 
demands. Seller shall not, except with the prior written consent of Acquiror 
(which will not be unreasonably withheld or delayed) or as otherwise required 
by law, make any payment with respect to, or settle, or offer to settle, any 
such demands.

          1.9. NONCOMPETITION AGREEMENT.  Simultaneously with the execution 
of this Agreement, each of Edward J. Zapp and John Leisen shall enter into a 
noncompetition agreement (the "Noncompetition Agreement") with Acquiror 
providing: (i) that such individuals shall not, for a period of five years 
after the Effective Date, (A) engage in the banking or financial services

consideration to be paid by Acquiror to each such individual in an annual 
amount of $200,000 for the period specified therein, subject to annual

condition of Acquiror and its subsidiaries, taken as a whole.

          2.2. AUTHORITY RELATIVE TO THIS AGREEMENT; NON-CONTRAVENTION. 
Acquiror has the requisite corporate power and authority to enter into this

untrue statement of a material fact or omit to state a material fact required 
to be stated therein or necessary to make the statements therein, in light of 
the circumstances under which they were made, not misleading and (y) complied 
as to form in all material respects with the applicable laws and rules and 
regulations of the SEC.  Since January 1, 1994, Acquiror has filed in a

in the business of Acquiror or its subsidiaries, taken as a whole, that, 
taken together with other events, occurrences and developments with respect 
to such business, has had or would reasonably be expected to have a material 
adverse effect on the business operations or financial condition of Acquiror

applicability or interpretations thereof by courts or governmental 
authorities and (b) changes in generally accepted accounting principles or 
regulatory accounting requirements applicable to banks and their holding 
companies generally.

and its subsidiaries has filed each report or other filing it was required to 
file with any federal or state banking or bank holding company or other 
regulatory authority having jurisdiction over it (together with all exhibits 
thereto, the "Acquiror Regulatory Reports"), except for such reports and 
filings which the failure to so file would not have a material adverse effect 
on the business, operations or financial condition of Acquiror and its 
subsidiaries, taken as a whole.  As of their respective dates or as 
subsequently amended prior to the date hereof, each of the Acquiror 
Regulatory Reports was true and correct in all material respects and complied

contained in this Agreement are true and correct in all material respects, 
and such representations and warranties do not omit any material fact 
necessary to make the statements contained therein, in light of the 
circumstances under which they were made, not misleading. There is no fact 
known to Acquiror which has not been disclosed to Seller pursuant to this 
Agreement and the Schedules hereto which would have or would reasonably be 
expected to have a material adverse effect on the business, operations or 
financial condition of Acquiror and its subsidiaries, taken as a whole, or 
the ability of Acquiror to consummate the transactions contemplated hereby.

          2.9. REGULATORY APPROVALS.  As of the date hereof, Acquiror is not

have been so reflected.  Neither Seller nor any Subsidiary have any 
Liabilities except (a) as reflected on the Latest Balance Sheets, (b) 
Liabilities which have arisen after the date of the Latest Balance Sheets in 
the ordinary course of business, none of which is a material uninsured 
liability, or (c) as otherwise disclosed on Schedule 3.8.  As of the date of

          3.11.     PROPERTIES.

          (a)  Each of Seller and the Subsidiaries owns good and marketable 
title to all of the real property and all of the personal property, fixtures, 
furniture and equipment reflected on the Latest Balance Sheets or acquired 
since the date thereof (other than real property reflected on the Latest 
Balance Sheets as OREO), free and clear of all liens and encumbrances, except 
for (i) mortgages on real property set forth on Schedule 3.11, (ii) 
encumbrances which do not materially affect the value of, or interfere with 
the past or future use or ability to convey, the property subject thereto or 
affected thereby, (iii) liens for current taxes and special assessments not 
yet due and payable, (iv) leasehold estates with respect to multi-tenant 
buildings owned by Seller or any Subsidiary, which leases are identified on 
Schedule 3.11, and (v) property disposed of since the date of the Latest 
Balance Sheets in the ordinary course of business; provided, that no disposal 
of any real property shall be considered to be in the ordinary course of 
business.

          (b)  Schedule 3.11 correctly sets forth a brief description, 
including the term, of each lease for real or personal property to which 
Seller or any Subsidiary is a party as lessee.  Seller has delivered to 
Acquiror complete and accurate copies of each of the leases described on 
Schedule 3.11, and none of such leases has been modified in any material 
respect, except to the extent that such modifications are disclosed by the 
copies delivered to Acquiror.  The leases described on Schedule 3.11 are in 
full force and effect in all material respects.  Each of Seller and the 
Subsidiaries, as the case may be (if lessee under such lease), has a valid 
and existing leasehold interest under each lease described on Schedule 3.11 
for the term set forth therein.  With respect to the leases described on and 
except as set forth on Schedule 3.11, neither Seller nor any Subsidiary is in 
default, and, to the best knowledge of Seller, none of the other parties to 
any of such leases is in default, and, to the best knowledge of Seller, no 
circumstances (not in the control of Seller or any Subsidiary) exist which 
could result in such a default under any of such leases.  

          (c)  To the best knowledge of Seller, there has been no 
cancellation, breach or anticipated breach by any other party to any lease 
described on Schedule 3.11.  The rent rolls set forth on Schedule 3.11 are 
true and complete in all material respects and describe all occupancies and 
the material terms of each occupancy.

          (d)  Except as set forth in Schedule 3.11, all of the buildings, 
fixtures, furniture and equipment necessary for the conduct of the business 
of Seller or any Subsidiary are in good condition and repair, ordinary wear 
and tear excepted, and are usable in the ordinary course of business.  Each 
of Seller and the Subsidiaries owns, or leases under valid leases, all 
buildings, fixtures, furniture, 

                                     A-13
<PAGE>

personal property, land improvements and equipment necessary for the conduct 
of its business as it is presently being conducted.

          (e)  Except as set forth in Schedule 3.11, neither Seller nor any 
Subsidiary and none of the buildings owned or leased by Seller or any 
Subsidiary is in violation of any applicable zoning ordinance or other law, 
regulation or requirement relating to the operation of any properties used in 
the operation of its business, including, without limitation, applicable 
environmental protection laws and regulations, which violations would, 
individually or in the aggregate, have a material adverse effect on the 
business, operations or financial condition of Seller and the Subsidiaries, 
taken as a whole; and neither Seller nor any Subsidiary has received any 
notice of any such violation, or of the existence of any condemnation 
proceeding with respect to any properties owned or leased by Seller or any 
Subsidiary.  Except as set forth in Schedule 3.11, no Hazardous Materials (as 
defined below) have been deposited or disposed of in, on or under Seller's or 
any Subsidiary's owned or leased properties (including properties owned, 
managed or controlled by any Bank in connection with its lending or fiduciary 
operations) during the period in which Seller or any Subsidiary has owned, 
occupied, managed, controlled or operated such properties. Except as set 
forth on Schedule 3.11, to the best knowledge of Seller, no prior owners, 
occupants or operators of all or any part of Seller's or any Subsidiary's 
owned or leased properties (including properties owned, managed or controlled 
by any Bank in connection with its lending or fiduciary operations) ever used 
such properties as a dump or gasoline service station, or deposited, disposed 
of or allowed to be deposited or disposed of in, on or under such properties 
any Hazardous Materials.  Except as disclosed on Schedule 3.11, no asbestos 
or any material amount of ureaformaldehyde materials exists in or on any of 
Seller's or the Subsidiary's owned or leased properties (including properties 
owned, managed or controlled by any Bank in connection with its lending or 
fiduciary operations), and no electrical transformers or capacitors, other 
than those owned by public utility companies, on such properties contain any 
PCBs.

          As used in this Section 3.11, the following terms shall have the 
following meanings:

          (i)  "Hazardous Materials" means any dangerous, toxic or hazardous
     pollutant, contaminant, chemical, waste, material or substance as defined
     in or governed by any federal, state or local law, statute, code,
     ordinance, regulation, rule or other requirement relating to such substance
     or otherwise relating to the environment or human health or safety,
     including without limitation any waste, material, substance, pollutant,
     petroleum or petroleum by product or contaminant that might cause any
     injury to human health or safety or to the environment or might subject
     Seller or any Subsidiary or, after the Effective Time, Acquiror or any of
     its affiliates, or any of their respective directors or officers, to any
     imposition of costs or liability under any Environmental Laws.

          (ii) "Environmental Laws" means all applicable federal, state, local
     and foreign laws, rules, regulations, codes, ordinances, orders, decrees,
     directives, permits, licenses and judgments relating to pollution,
     contamination or protection of health, safety or the environment
     (including, without limitation, all applicable federal, state, local and
     foreign laws, rules, regulations, codes, ordinances, orders, decrees,
     directives, permits, licenses and judgments relating to Hazardous Materials
     in effect as of the date of this Agreement).

          (f)  Except as set forth in Schedule 3.11, there are no aboveground 
or underground tanks (excluding hot water storage or propane tanks) located 
under, in or about, nor, to the best knowledge of Seller, have there ever 
been any such tanks located under, in or about, any of Seller's or the 
Subsidiary's owned or leased properties (including properties owned, managed 
or controlled by any Bank in connection with its lending or fiduciary 
operations).

          3.12.     TAX MATTERS.  Except as disclosed on Schedule 3.12, each 
of Seller and the Subsidiaries and all members of any consolidated, 
affiliated, combined or unitary group of which Seller or any Subsidiary is a 
member have filed or will file all Tax (as hereinafter defined) and Tax 
information returns or reports required to be filed (taking into account 
permissible extensions) by them on or prior to the Effective Time, and have 
paid (or have accrued or will accrue, prior to the Effective Time, amounts 
for the payment of) all Taxes relating to the time periods covered by such 
returns and reports.  Except as disclosed on Schedule 3.12, the accrued taxes 
payable accounts for Taxes reflected on the Latest Balance Sheets (or the 
notes thereto) are sufficient for the payment of all unpaid Taxes of Seller 
or any Subsidiary accrued for or applicable to all periods ended on or prior 
to the date of the Latest Balance Sheets or which may subsequently be 
determined to be owing with respect to any such period.  Except as disclosed 
on Schedule 3.12, neither Seller nor any Subsidiary has waived any statute of 
limitations with respect to Taxes or agreed to any extension of time with 
respect to an assessment or deficiency for Taxes. Each of Seller and the 
Subsidiaries has paid or will pay in a timely manner and as required by law 
all Taxes due and payable by it or which it is obligated to withhold from 
amounts owing to any employee or third party.  Except as disclosed on 
Schedule 3.12, all Taxes which will be due and payable, whether now or 
hereafter, for any period ending on, prior to or including the Effective 
Time, shall have been paid by or on behalf of Seller and the Subsidiaries or 
shall be reflected on the books of Seller and the Subsidiaries as an accrued 
Tax liability determined in a manner which is consistent with past practices 
and the Latest Balance Sheets, without taking account of the Merger.  The 
aggregate amount of all such accruals for Tax liability for any such period 
will be set forth on Schedule 3.12 (and a good faith estimate of such amount 
shall be provided in writing to Acquiror at least 10 days prior to the 
Effective Time). In the five years prior to the date of this Agreement, no 
Tax returns of Seller or any Subsidiary have been audited by any governmental 
authority other than as disclosed on Schedule 3.12; and, except as set forth 
on Schedule 3.12, there are no unresolved questions, claims or disputes 
asserted by any relevant taxing authority concerning the liability for Taxes 
of Seller or any Subsidiary. Neither Seller nor any Subsidiary has made an 
election under Section 341(f) of the Code for any taxable years not yet 
closed for statute of limitations purposes.  In the five years prior to the 
date of this Agreement, no demand or claim has been made against Seller or 
any Subsidiary with respect to any Taxes arising out of membership or 
participation in any consolidated, affiliated, combined or unitary group of 
which Seller or any Subsidiary was at any time a member.  The tax 
identification number for Seller and each Subsidiary are set forth on 
Schedule 3.12.  For purposes of this Agreement, the term "Tax" shall mean any 
federal, state, local or foreign income, gross receipts, license, payroll, 
employment, excise, severance, stamp, occupation, premium, property or 
windfall profits tax, environmental tax, customs duty, capital stock, 
deposits, franchise, employees' income withholding, foreign or domestic 
withholding, social security, unemployment, disability, workers' 
compensation, employment-related insurance, real property, personal property, 
sales, use, transfer, value added, alternative or add-on minimum or other 
tax, fee, assessment or charge of any kind whatsoever, including any 
interest, penalties or additions to, or additional amounts in respect of the 
foregoing, for each of Seller, the Subsidiaries and all members of any 
consolidated, affiliated, combined or unitary group of which Seller or any 
Subsidiary is a member.

date, (iv) is a party to any (A) contract or group of related contracts with

contracts, (C) contract, agreement, arrangement or understanding that

business) that would, individually or in the aggregate, have a material 
adverse effect on the business, operations or financial condition of Seller 
and the Subsidiaries, taken as a whole; (ii) each of Seller and the 
Subsidiaries has performed all obligations required to be performed by it 
prior to the date hereof in connection with the contracts or commitments set 
forth on Schedule 3.13, and neither Seller nor any Subsidiary is in receipt 
of any claim of default under any contract or commitment set forth on 
Schedule 3.13, except for any failures to perform, breaches or defaults which 
would not, individually or in the aggregate, have a material adverse effect 
on the business, operations or financial condition of Seller and the

         3.20.     COMPLIANCE WITH LAWS; PERMITS.  To the best knowledge of
Seller, each of Seller and the Subsidiaries has complied in all respects with
all applicable laws and regulations of foreign, federal, state and local
governments and all agencies thereof which affect the business or any owned or
leased properties of Seller or any Subsidiary and to which Seller or any
Subsidiary may be subject (including, without limitation, the Occupational
Safety and Health Act of 1970, the Home Owners Loan Act, the Federal Deposit
Insurance Act, as amended (the "FDIA"), the Real Estate Settlement Procedures
Act, the Home Mortgage Disclosure Act of 1975, the Fair Housing Act, the Equal
Credit Opportunity Act and the Federal Reserve Act, each as amended, and any
other state or federal acts (including rules and regulations thereunder)
regulating or otherwise affecting employee health and safety or the
environment), except where the failure to so comply would not, individually or
in the aggregate, have a material adverse effect on the business, operations or
financial condition of Seller and the Subsidiaries, taken as a whole, or
Seller's ability to consummate the transactions contemplated hereby; and no
claims have been filed by any such governments or agencies against Seller or any
Subsidiary alleging such a violation of any such law or regulation which have
not been resolved to the satisfaction of such governments or agencies.  Each of
Seller and the Subsidiaries holds all of the permits, licenses, certificates and
other authorizations of foreign, federal, state and local governmental agencies
required for the conduct of its business, except where failure to obtain such
authorizations would not, individually or in the aggregate, have a material
adverse effect on the business, operations or financial condition of Seller and
the Subsidiaries, taken as whole, or the ability of Seller to consummate the
transactions contemplated hereby.  Neither Seller nor any Subsidiary is subject
to any cease and desist order, written agreement or memorandum of understanding
with, or is 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 agreement letter from, or has adopted any board resolutions at the
request of, federal or state governmental authorities charged with the
supervision or regulation of banks or bank holding companies or engaged in the
insurance of bank deposits (collectively, the "Bank Regulators"), nor have any
of Seller or the Subsidiaries been advised by any Bank Regulator that it is
contemplating issuing or requesting (or is considering the appropriateness of
issuing or requesting) any such order, directive, written agreement, memorandum
of understanding, extraordinary supervisory letter, commitment letter, board
resolutions or similar undertaking.  Neither Seller or any Bank is subject to
Section 32 of the FDIA.

         3.21.     ADMINISTRATION OF FIDUCIARY ACCOUNTS.  Each Bank has
properly administered, in all respects material and which could reasonably be
expected to be material to the business, operations or financial condition of
Seller and the Subsidiaries, taken as a whole, all accounts for which it acts as
a fiduciary, including but not limited to accounts for which it serves as a
trustee, agent, custodian, personal representative, guardian, conservator or
investment advisor, in accordance with the terms of the governing documents and
applicable state and federal law and regulation and common law.  None of Seller,
the Subsidiaries or any of their respective officers or directors has committed
any breach of trust with respect to any such fiduciary account which is material
to or could reasonably be expected to be material to the business, operations or
financial condition of Seller and the Subsidiaries, taken as a whole, and the
accountings for each such fiduciary account are true and correct in all material
respects and accurately reflect the assets of such fiduciary account in all
material respects.

         3.22.     DISCLOSURE.  The representations and warranties of Seller
contained in this Agreement are true and correct in all material respects, and
such representations and warranties do not omit any material fact necessary to
make the statements contained therein, in light of the circumstances under which
they were made, not misleading. There is no fact known to Seller which has not
been disclosed to Acquiror pursuant to this Agreement and the Schedules hereto
which would have or would reasonably be expected to have a material adverse
effect on the business, operations or financial condition of Seller and the
Subsidiaries, taken as a whole, or the ability of Seller to consummate the
transactions contemplated hereby.

         3.23.     REGULATORY APPROVALS.  As of the date hereof, Seller is not
aware of any fact that would likely result in the regulatory approvals specified
in Section 5.1 not being obtained.

         3.24.     INTEREST RATE RISK MANAGEMENT INSTRUMENTS.

         (a)  Schedule 3.24 sets forth a true, correct and complete list of all
interest rate swaps, caps, floors and option agreements and other interest rate
risk management arrangements to which Seller or any Bank is a party or by which
any of their properties or assets may be bound.  Seller has delivered to
Acquiror true, correct and complete copies of all such interest rate risk
management agreements and arrangements.

         (b)  All interest rate swaps, caps, floors and option agreements and
other interest rate risk management arrangements to which Seller or any Bank is
a party or by which any of their properties or assets may be bound were entered
into in the ordinary course of business and, to the knowledge of Seller, in
accordance with prudent banking practice and applicable rules, regulations and
policies of the Bank Regulators and with counterparties believed to be
financially responsible at the time and are legal, valid and binding obligations
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.  Each of Seller and the Subsidiaries has duly
performed in all material respects all of its obligations thereunder to the
extent that such obligations to perform have accrued; and to the knowledge of
Seller, there are no breaches, violations or defaults or allegations or
assertions of such by any party thereunder.

         3.25.     DISCLOSURES IN SCHEDULES.   Any matter disclosed in any
Schedule to this Agreement shall be deemed to have been disclosed in all
Schedules to this Agreement.

         3.26.     FAIRNESS OPINION.  The Board of Directors of Seller has
received the opinion of Dain Bosworth Incorporated, financial advisor to the
Board of Directors of Seller, dated September 11, 1997 (the "Fairness Opinion")
to the effect that the Merger Consideration is fair to the shareholders of
Seller from a financial point of view, and such opinion is in a form and
substance reasonably satisfactory to the Board of Directors.

withholding or employment tax returns or statements), or consent to any
adjustment or otherwise compromise or settle any matters with respect to Taxes,
without prior consultation with Acquiror; provided, further, that neither Seller
nor any Subsidiary shall make any election or take any other discretionary
position with respect to Taxes, in a manner inconsistent with past practices,
without the prior written approval of Acquiror.  In the event the granting or
withholding of such approval by Acquiror results in additional Taxes owing for
any Tax period ending on or before the Effective Time, liability for such
additional Taxes shall not cause any representation of Seller relating to Taxes
to be untrue.  Seller shall provide Acquiror with a copy of appropriate
workpapers, schedules, drafts and final copies of each federal and state income
Tax return or election of Seller and the Subsidiaries (including returns of all
Plans) at least ten days before filing such return or election and shall
reasonably cooperate with any request by Acquiror in connection therewith. 

         (b)  Acquiror, in its sole and absolute discretion, will file (or
cause to be filed) all Tax returns of Seller and the Subsidiaries due after the
Effective Time.  After the Effective Time, Acquiror, in its sole and absolute
discretion and to the extent permitted by law, shall have the right to amend,
modify or otherwise change all Tax returns of Seller and the Subsidiaries for
all Tax periods.  To the extent Acquiror amends any such Tax returns, other than
an amendment at the request of the applicable federal, state, local or foreign
Tax authority, and such amendment results in additional Taxes owing for any Tax
period ending on or before the Effective Time, such additional Taxes shall not
cause any representation of Seller relating to Taxes to be untrue.

         5.9. SHAREHOLDER APPROVAL; REGISTRATION STATEMENT.  

         (a)  Seller shall call a meeting of its shareholders for the purpose
of voting upon this Agreement and the Merger, and shall schedule such meeting
based on consultation with Acquiror. The Board of Directors of Seller shall
recommend that the shareholders approve this Agreement and

                                          A-27
<PAGE>

the Merger, and shall use its best efforts (including, without limitation, 
soliciting proxies for such approval) to obtain such shareholder approval. 

         (b)  For the purposes of (i) holding a meeting of the shareholders of
Seller to approve this Agreement and the Merger and (ii) registering the
Acquiror Common Stock to be issued to holders of Seller Common Stock in
connection with the Merger with the SEC and with applicable state securities
authorities, the parties hereto shall cooperate in the preparation of a
registration statement on Form S-4 (such registration statement, together with
all and any amendments and supplements thereto, being herein referred to as the
"Registration Statement"), which shall include a prospectus/proxy statement
satisfying all applicable requirements of the 1933 Act, the 1934 Act and
applicable Blue Sky Laws (such prospectus/proxy statement, together with any and
all amendments or supplements thereto, being herein referred to as the
"Prospectus/Proxy Statement").

         (c)  Acquiror shall furnish such information concerning Acquiror as 
is necessary in order to cause the Prospectus/Proxy Statement, insofar as it 
relates to Acquiror, to be prepared in accordance with Section 5.9(b).  
Acquiror agrees promptly to notify Seller if at any time prior to the Seller 
shareholder meeting any information provided by Acquiror in the 
Prospectus/Proxy Statement becomes incorrect or incomplete in any material 
respect, and to provide the information needed to correct such inaccuracy or 
omission.

         (d)  Seller shall furnish Acquiror with such information concerning 
Seller and the Subsidiaries as is necessary in order to cause the 
Prospectus/Proxy Statement, insofar as it relates to Seller and the 
Subsidiaries, to be prepared in accordance with Section 5.9(b).  Seller 
agrees promptly to notify Acquiror if at any time prior to the Seller 
shareholder meeting any information provided by Seller in the 
Prospectus/Proxy Statement becomes incorrect or incomplete in any material 
respect, and to provide Acquiror with the information needed to correct such 
inaccuracy or omission.

         (e)  Acquiror shall promptly file the Registration Statement with the
SEC and applicable state securities agencies.  Acquiror shall use reasonable
efforts to cause the Registration Statement to become effective under the 1933
Act and applicable Blue Sky Laws at the earliest practicable date.  Seller
hereby authorizes Acquiror to utilize in the Registration Statement the
information concerning Seller and the Subsidiaries provided to Acquiror for the
purpose of inclusion in the Prospectus/Proxy Statement.  Seller shall have the
right to review and comment on the form of proxy statement included in the
Registration Statement.  Acquiror shall advise Seller promptly when the
Registration Statement has become effective and of any supplements or amendments
thereto, and Acquiror shall furnish Seller with copies of all such documents. 
Prior to the Effective Time or the termination of this Agreement, each party
shall consult with the other with respect to any material (other than the
Prospectus/Proxy Statement) that might constitute a "prospectus" relating to the
Merger within the meaning of the 1933 Act.

         (f)  Acquiror shall use reasonable efforts to cause to be delivered to
Seller a letter relating to the Registration Statement from Ernst & Young LLP,
Acquiror's independent auditors, dated a date within two business days before
the date on which the Registration Statement shall become effective and
addressed to Seller, in form and substance reasonably satisfactory to Seller and
customary in scope and substance for letters delivered by independent public
accountants in connection with registration statements similar to the
Registration Statement.

         (g)  Seller shall use reasonable efforts to cause to be delivered to
Acquiror a letter relating to the Registration Statement from Larsen Allen
Weishair LLP, Seller's independent auditors, dated a date within two business
days before the date on which the Registration Statement shall become effective
and addressed to Acquiror, in form and substance reasonably satisfactory to
Acquiror

                                          A-28
<PAGE>

and customary in scope and substance for letters delivered by independent 
public accountants in connection with registration statements similar to the 
Registration Statement.

         (h)  Acquiror shall bear the costs of all SEC filing fees with respect
to the Registration Statement and the costs of qualifying the shares of Acquiror
Common Stock under the Blue Sky Laws, to the extent necessary.  Acquiror shall
bear all printing and mailing costs in connection with the preparation and
mailing of the Prospectus/Proxy Statement to Seller shareholders.   Acquiror and
Seller shall each bear their own legal and accounting expenses in connection
with the Registration Statement.

         5.10.  ESTABLISHMENT OF ACCRUALS.  If requested by Acquiror, on the 
business day immediately prior to the Effective Time, the Banks shall, 
consistent with generally accepted accounting principles, establish such 
additional accruals and reserves as may be necessary to conform the Banks' 
accounting and credit loss reserve practices and methods to those of Acquiror 
(as such practices and methods are to be applied to the Banks from and after 
the Effective Time) and reflect Acquiror's plans with respect to the conduct 
of the Banks' business following the Merger and to provide for the costs and 
expenses relating to the consummation by the Banks of the transactions 
contemplated by this Agreement.  The establishment of such accruals and 
reserves shall not be an adjustment to the Final Balance Sheet or the Final 
Retained Earnings and shall not, in and of itself, constitute a breach of any 
representation or warranty of Seller contained in this Agreement or 
constitute a material adverse change in the business, operations or financial 
condition of Seller and the Banks, taken as a whole.

         5.11.  EMPLOYEE MATTERS. 

         (a)  GENERAL.  Subject to the following agreements, after the 
Effective Time, Acquiror shall have the right to continue, amend, merge or 
terminate any of the Plans (as defined in Section 3.17) in accordance with 
the terms thereof and subject to any limitation arising under applicable law, 
including tax qualification requirements.  Until Acquiror shall take such 
action, however, such Plans shall continue in force for the benefit of 
present and former employees of Seller or any Subsidiary who have any present 
or future entitlement to benefits under any of the Plans ("Seller Employees").

         (b)  SALARY CONTINUATION AGREEMENTS.  Acquiror expressly assumes and
agrees to be bound by the terms of the salary continuation agreements with each
of Edward J. Zapp and John Leisen as disclosed to Acquiror (the "Salary
Continuation Agreements").
         
         (c)  SEVERANCE.   Acquiror shall enter into a severance agreement
substantially in the form provided by Acquiror to Seller with each of the eight
individuals mutually agreed to by Acquiror and Seller.  With respect to
employees of Seller or any Subsidiary not subject to any other severance
agreement, Acquiror shall pay severance to such employees in accordance with
Acquiror's General Severance Pay Program, as the same may be amended from time
to time.

         (d)  LIMITATION ON ENFORCEMENT. This Section 5.11 is an agreement 
solely between Seller and Acquiror. Nothing in this Section 5.11, whether 
express or implied, confers upon any employee of Seller, any Subsidiary or 
Acquiror or any other person, any rights or remedies, including, but not 
limited to: (i) any right to employment or recall, (ii) any right to 
continued employment for any specified period or (iii) any right to claim any 
particular compensation, benefit or aggregate of benefits, of any kind or 
nature whatsoever, as a result of this Section 5.11.

         5.12.     TAX TREATMENT.  None of Seller, the Subsidiaries or 
Acquiror shall take any action which would disqualify the Merger as a 
"reorganization" that would be tax-free to the shareholders of Seller 
pursuant to Section 368(a) of the Code.

                                          A-29
<PAGE>

         5.13.  LOAN PARTICIPATIONS.  Seller agrees that it will not sell any 
loan participation or renew any loan participation without first offering to 
sell such loan participation to Acquiror on the same terms as such sale or 
renewal.

         5.14.     AFFILIATE/REPRESENTATION LETTERS.  Seller shall use its 
best efforts to obtain and deliver to Acquiror prior to the Effective Date 
(a) a signed representation letter substantially in the form of Exhibit A 
hereto and otherwise satisfactory to Acquiror from each shareholder of Seller 
who may reasonably be deemed an "affiliate" of Seller within the meaning of 
such term as used in Rule 145 under the 1933 Act and (b) signed 
representation letters from all of the shareholders of Seller holding to the 
effect that it is each such shareholder's plan and intent to hold (and not to 
sell, transfer or otherwise dispose of) at least 50% of the shares of 
Acquiror Common Stock received by such shareholder in the Merger; provided, 
however, that in the event that the proposed Treasury regulations regarding 
the "continuity of interest" test applicable to transactions intending to 
qualify as reorganizations within the meaning of Section 368(a) of the Code 
are adopted as final regulations in substantially the form in which they were 
proposed on December 20, 1996 with an effective date of such regulations on 
or prior to the Effective Date, Seller's obligations under Section 5.14(b) 
shall terminate.

         5.15.     UPDATED SCHEDULES.  On a date 15 business days prior to the
Effective Date and on the Effective Date, Seller shall modify any Schedule to
this Agreement or add any Schedule or Schedules hereto for the purpose of making
the representations and warranties to which any such Schedule relates true and
correct in all material respects as of such date, whether to correct any
misstatement or omission in any Schedule or to reflect any additional
information obtained by Seller subsequent to the date any Schedule was
previously delivered by Seller to Acquiror.   Notwithstanding the foregoing, any
updated Schedule shall not have the effect of making any representation or
warranty contained in this Agreement true and correct in all material respects
for purposes of Section 6.3(a) hereof.

         5.16.     280G APPROVAL.  Seller shall make no payments that
separately or in the aggregate could or would result in the payment of any
"excess parachute payments" within the meaning of Section 280G of the Code,
unless and until such payments are approved by the shareholders of Seller in
accordance with the provisions of Sections 280G(b)(5)(A)(ii) and 280G(b)(5)(B)
of the Code, and Seller shall use its best efforts to obtain shareholder
approval of any such payments in accordance with such Sections of the Code prior
to the Effective Time.

         5.17.     AGREEMENT TO PURCHASE CONVERTED SHARES.  Commencing
immediately following the Effective Time and from time to time thereafter until
the second anniversary of the Effective Date, upon request, Acquiror shall
purchase from the former shareholders of Seller up to an aggregate of 30% of the
total number of shares of Acquiror Common Stock issued upon conversion of Seller
Common Stock in the Merger (the "Merger Shares").  The purchase price for each
such Merger Share purchased by Acquiror shall be equal to the closing price for
a share of Acquiror Common Stock as quoted on the New York Stock Exchange on the
trading day immediately prior to the day on which such purchase occurs.  At any
such time as Acquiror has purchased a number of shares of Acquiror Common Stock
representing 30% of the total number of Merger Shares, Acquiror's obligation to
purchase shares as herein provided shall cease.  In addition, Acquiror may, in
its sole and absolute discretion, suspend its obligation to purchase shares in
the event of restrictions imposed by federal securities laws or accounting
requirements for transactions accounted for as a pooling-of-interests.

         5.18.     PURCHASE OF CERTAIN ASSETS AT BOOK VALUE. Immediately prior
to the Effective Time, Edward J. Zapp shall purchase from Seller the assets
listed on Schedule 5.18 at the book value of such assets as of the last day of
the month preceding the month in which the Effective Date occurs.

    waiting periods shall have lapsed.  None of such approvals shall contain
    any conditions or restrictions that Acquiror reasonably believes will
    materially restrict or limit the business or activities of Acquiror, Seller
    or the Subsidiaries or have a material adverse effect on, or would be
    reasonably likely to have a material adverse effect on, the business,
    operations or financial condition of Acquiror and its subsidiaries, taken
    as a whole, on the one hand, or Seller and the Subsidiaries, taken as a
    whole, on the other hand. 

         (b)  NO INJUNCTION.  No injunction or other order entered by a state
    or federal court of competent jurisdiction shall have been issued and

    entered, enforced, promulgated, issued or deemed applicable to the
    transactions contemplated hereby by any federal, state or other court,
    government or governmental authority or agency, which would reasonably be
    expected to result, directly or indirectly, in (i) restraining or
    prohibiting the consummation of the transactions contemplated hereby or
    obtaining material damages from Seller, any Subsidiary, Acquiror or any of
    Acquiror's subsidiaries in connection with the transactions contemplated

    to dispose of or to hold separately all or a material portion of the
    business or assets of Acquiror or any of its subsidiaries or of Seller or
    any Subsidiary, as a result of the transactions contemplated hereby, or
    (iii) requiring direct or indirect divestiture by Acquiror of any of its

    correct as of the date hereof, and shall be true and correct as of the
    Effective Time as if made at and as of the Effective Time, except where the
    failure to be true and correct would not have, or would not reasonably be
    expected to have, a material adverse effect on the business, operations or
    financial condition of Acquiror and its subsidiaries, taken as a whole; and
    Acquiror shall in all material respects have performed each obligation and
    agreement and complied with each covenant to be performed and complied with
    by it hereunder at or prior to the Effective Time.

         (b)  OFFICER'S CERTIFICATE.  Acquiror shall have furnished to Seller a
    certificate of the Chief Financial Officer of Acquiror, dated as of the

    not been fulfilled.

         (c)  ACQUIROR SECRETARY'S CERTIFICATE.  Acquiror shall have furnished

    amended or rescinded and (iii) an incumbency certificate dated as of the

    agreement, certificate or other instrument executed pursuant hereto.

         (d)  MATERIAL ADVERSE CHANGE.  Since the date of this Agreement, there
    shall have been no material adverse change in, and no event, occurrence or
    development in the business of Acquiror or its subsidiaries that, taken
    together with other events, occurrences and developments with respect to
    such business, would have or would reasonably be expected to have a
    material adverse effect on, the business, operations or financial condition
    of Acquiror and its subsidiaries, taken as a whole.

         (e)  CHANGE IN CONTROL OF ACQUIROR.  Acquiror shall not have merged,
    or announced an agreement to merge, into another corporation, or sold all
    or substantially all of its assets, or had one person or group acquire, or
    had one person or group announce its intent to acquire, directly or
    indirectly, beneficial ownership of more than 50% of the outstanding
    Acquiror Common Stock.

         (f)  REGISTRATION STATEMENT; LISTING.  The registration statement on
    Form S-4 referred to in Section 5.9 shall have been declared and shall
    remain effective and no stop order suspending the effectiveness of such
    registration statement shall have been issued and no proceeding for that
    purpose shall have been initiated or threatened by the SEC, and the shares

    satisfactory to Seller and

                                          A-32
<PAGE>

    Acquiror, to the effect that, on the basis of the facts, representations
    and assumptions set forth in such opinion which are consistent with the 
    state of facts existing at the Effective Time, the Merger will be treated 
    for federal income tax purposes as a reorganization within the meaning of 
    Section 368(a) of the Code and that accordingly: (i) no gain or loss will 
    be recognized for federal income tax purposes by Acquiror or Seller as a 
    result of the consummation of the Merger; (ii) no gain or loss will be 
    recognized for federal income tax purposes by shareholders of Seller who 
    exchange their Seller Common Stock solely for Acquiror Common Stock pursuant
    to the Merger (except to the extent of any cash received in lieu of 
    fractional shares); and (iii) the tax basis of the Acquiror Common Stock 
    received by shareholders of Seller who exchange all of their Seller Common 
    Stock solely for Acquiror Common Stock in the Merger will be the same as the
    tax basis of the Seller Common Stock surrendered in exchange therefor.  In 
    rendering such opinion, such counsel may require and rely upon 
    representations and covenants of Seller and Acquiror and such other persons
    as such counsel deems appropriate.

         6.3. ADDITIONAL CONDITIONS TO OBLIGATION OF ACQUIROR.  The obligation
of Acquiror to consummate the transactions contemplated hereby in accordance

    warranties of Seller in this Agreement shall have been true and correct as
    of the date hereof, and such representations and warranties shall be true

    or would not reasonably be expected to have, a material adverse effect on
    the business, operations or financial condition of Seller and the
    Subsidiaries, taken as a whole, (ii) for the representations and warranties
    set forth in Section 3.5(b) which shall be true and correct in all materials
    respects as of the date of this Agreement, and the lists provided pursuant
    to Section 5.2 shall be true and correct in all material respects as of the
    respective dates of each such list and (iii) for the representations and
    warranties set forth in the first sentence of Section 3.16 which may be
    updated for facts arising after the date hereof and which shall be true and

    respects have performed each obligation and agreement and complied with
    each covenant to be performed and complied with by them hereunder at or
    prior to the Effective Time.

         (d)  MATERIAL ADVERSE CHANGE.  Since the date of this Agreement, there
    shall have been no material adverse change in, and no event, occurrence or
    development in the business of Seller or the Subsidiaries that, taken
    together with other events, occurrences and developments with respect to
    such business, would have or would reasonably be expected to have a
    material adverse effect on, the business, operations or financial condition
    of Seller and the Subsidiaries, taken as a whole; provided, however, that a
    material adverse change or a material adverse effect shall not be deemed to
    include the impact of (a) changes in banking and similar laws of general
    applicability or interpretations thereof by courts or governmental
    authorities and (b) changes in generally accepted accounting principles or
    regulatory accounting requirements applicable to banks and their holding
    companies generally.

         (e)  SELLER COMMON STOCK.  As of the Effective Time, all issued and

    forth on Schedule 3.3.

    Final Balance Sheet as provided in Section 1.3.

         (h)  TAX OPINION.  Acquiror shall have received an opinion of Dorsey &
    Whitney LLP, dated as of the Effective Time and in form and substance
    satisfactory to Seller and Acquiror, to the effect that, on the basis of
    the facts, representations and assumptions set forth in such opinion which
    are consistent with the state of facts existing at the Effective Time, the
    Merger will be treated for federal income tax purposes as a reorganization
    within the meaning of Section 368(a) of the Code and that accordingly: (i)
    no gain or loss will be recognized for federal income tax purposes by
    Acquiror or Seller as a result of the consummation of the Merger; (ii) no
    gain or loss will be recognized for federal income tax purposes by
    shareholders of Seller who exchange their Seller Common Stock solely for
    Acquiror Common Stock pursuant to the Merger (except to the extent of any
    cash received in lieu of fractional shares); and (iii) the tax basis of the
    Acquiror Common Stock received by shareholders of Seller who exchange all
    of their Seller Common Stock solely for Acquiror Common Stock in the Merger
    will be the same as the tax basis of the Seller Common Stock surrendered in
    exchange therefor.  In rendering such opinion, such counsel may require and
    rely upon representations and covenants of Seller and Acquiror and such
    other persons as such counsel deems appropriate.

         (c)  by either Acquiror or Seller if the Effective Time is not on or
before February 28, 1998 (unless the failure to consummate the Merger by such

notice of such termination and the reasons therefor to the other parties.

(b) for the obligations of the parties under Article 8, and (c) that the 
covenants contained in Sections 5.4, 5.7(b), (c) and (d) hereof shall survive

                                    THE DEPOSIT

         8.1. OPTION DEPOSIT AND ESCROW DEPOSIT.  Prior to the date hereof, and
in consideration for certain covenants and agreements set forth in a letter
agreement heretofore entered into by and among the parties hereto setting forth
the general provisions of this Agreement, Acquiror has deposited $500,000 (the
"Option Deposit") in an escrow account.  Upon execution of this Agreement and in
consideration of the covenants and agreements of Seller herein, Acquiror shall
deposit in an escrow account with First Trust National Association (the "Escrow
Agent") for the benefit of Seller, and pursuant to the escrow agreement attached
hereto as Exhibit B, the sum of $1,000,000 (the "Escrow Deposit") plus the
Option Deposit (together, the "Deposit").  Interest on the applicable portion of

agent shall be paid by the party receiving the interest on the Escrow Deposit.

         8.2. RELEASE OF DEPOSIT TO SELLER.  If the Effective Time is delayed
beyond February 28, 1998 or if the Merger shall not have been consummated for
any reason on or prior to such date (unless the failure to consummate the Merger
by such date shall be due to the action or failure to act of Seller in breach of
Seller's obligations under this Agreement), other than the termination of this
Agreement pursuant to Section 7.1(b) due to a failure to satisfy the conditions
of Sections 6.1(f), 6.2(g), 6.3(a) or (g) hereof, the Escrow Agent shall pay the
Deposit, together with interest thereon, to Seller on the earlier of such
termination or such date.  If this Agreement is terminated pursuant to
Section 7.1(b), due to a failure to satisfy the conditions of Sections 6.1(f),
6.2(g), 6.3(a) or (g) hereof, the Escrow Agent shall pay the Option Deposit,
together with interest thereon, to the Seller on such termination.

before February 28, 1998, the Deposit shall be refunded to Acquiror.  If this
Agreement is terminated at any time pursuant to Section 7.1(b) due to a failure
to satisfy the conditions of Sections 6.1(f), 6.2(g), 6.3(a) or (g), or if the
Merger shall not have been consummated due to the action or failure to act of
Seller in breach of Seller's obligations under this Agreement, the Escrow
Deposit shall be refunded to Acquiror.

         9.1. PUBLIC STATEMENTS.  Neither Seller nor the Acquiror shall make
any public announcement or statement with respect to the Merger, this Agreement
or any related transactions without the approval of the other parties; provided,

context requires; provided, however, that neither Seller nor any Subsidiary 
shall at any time be considered a subsidiary of Acquiror for purposes of this 
Agreement.  The headings contained in this Agreement are for reference 
purposes only and shall not affect in any way the meaning or interpretation 
of this Agreement.  References to Sections and Articles refer to Sections and 
Articles of this Agreement unless otherwise stated.  Words such as "herein," 
"hereinafter," "hereof," "hereto," "hereby" and "hereunder," and words of 
like import, unless the context requires otherwise, refer to this Agreement 
(including the Exhibits and Schedules hereto).  As used in this Agreement, 
the masculine, feminine and neuter genders shall be deemed to include the 
others if the context requires.

         9.4. SEVERABILITY.  If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid, void
or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated, and the parties shall negotiate
in good faith to modify this Agreement and to preserve each party's anticipated
benefits under this Agreement.

         9.5. MISCELLANEOUS.  This Agreement (together with all other 
documents and instruments referred to herein): (a) constitutes the entire 
agreement, and supersedes all other prior agreements and undertakings, both 
written and oral, among the parties, with respect to the subject matter 
hereof; (b) is not intended to confer upon any person other than the parties 
hereto any rights or remedies hereunder (c) shall be governed in all 
respects, including validity, interpretation and effect, by the internal laws 
of the State of Minnesota, without giving effect to the principles of 
conflict of laws thereof; and (d) shall not be assigned by operation of law 
or otherwise.  This Agreement may be executed in two or more counterparts 
which together shall constitute a single agreement. 

         9.6. INVESTIGATION OF REPRESENTATIONS, WARRANTIES AND COVENANTS.  No
investigation made by or on behalf of the parties hereto or the results of any
such investigation shall constitute a waiver of any representation, warranty or
covenant of any other party.

         9.7. NO SURVIVAL OF REPRESENTATIONS.  The representations, warranties
and covenants made by Seller and Acquiror in this Agreement or in any instrument
delivered pursuant to this Agreement shall terminate on, and shall have no
further force or effect after, the Effective Time, except for those covenants
contained herein or therein which by their terms apply in whole or in part after

U.S. Bancorp
601 Second Avenue South
Minneapolis, Minnesota  55402-4302

Ladies and Gentlemen:

          1.   I have been advised that I might be considered to be an 
"affiliate," as that term is defined for purposes of paragraphs (c) and (d) 
of Rule 145 ("Rule 145") promulgated by the Securities and Exchange 
Commission (the "Commission") under the Securities Act of 1933, as amended 
(the "Securities Act"), of Zappco, Inc., a Minnesota corporation ("Zappco").

          2.   Pursuant to an Agreement and Plan of Merger dated September 
12, 1997 (the "Agreement"), by and between U.S. Bancorp, a Delaware 
corporation ("USBC"), and Zappco, it is contemplated that Zappco will merge 
with and into USBC and that all of the outstanding common stock, par value 
$1.00 per share, of Zappco ("Zappco Common Stock") will be converted into 
common stock, par value $1.25 per share, of USBC ("USBC Common Stock"), as 
set forth in the Agreement (the "Merger").  In connection with the Merger, I 
will receive my pro rata portion of the shares of USBC Common Stock upon 
distribution of the USBC Common Stock to the holders of Zappco Common Stock.

          3.   I hereby agree as follows:

               a.   I will not offer to sell, transfer or otherwise dispose 
of any of the shares of USBC Common Stock distributed to me pursuant to the 
Merger (the "Stock"), except (i) in compliance with the applicable provisions 
of Rule 145, (ii) in a transaction that is otherwise exempt from the 
registration requirements of the Securities Act, or (iii) in an offering 
registered under the Securities Act.

          4.   I consent to the endorsement of the Stock issued to me 
pursuant to the Merger with a restrictive legend which will read 
substantially as follows:

                         "The shares represented by this certificate were
               issued in a transaction to which Rule 145 promulgated under
               the Securities Act of 1933, as amended (the "Act"), applies,
               and may be sold or otherwise transferred only in compliance
               with the limitations of such Rule 145, or upon receipt by
               U.S. Bancorp of an opinion of counsel reasonably
               satisfactory to it that some other exemption from
               registration under the Act is available, or pursuant to a
               registration statement under the Act."

          USBC's transfer agent shall be given an appropriate stop transfer 
order and shall not be required to register any attempted transfer of the 
shares of the Stock, unless the transfer has been effected in compliance with 
the terms of this letter agreement, it being understood that USBC will 
promptly process all transfer requests effected in compliance with the terms 
of this letter agreement.

          5.   It is understood and agreed that this letter agreement shall 
terminate and be of no further force and effect and the legend set forth in 
paragraph 4 above shall be removed by delivery of substitute certificates 
without such legend, and the related stop transfer restrictions shall be 
lifted forthwith, if (i) any such shares of Stock shall have been registered 
under the Securities Act for sale, transfer or other disposition by me or on 
my behalf and are sold, transferred or otherwise disposed of, or (ii) any 
such shares of Stock are sold in accordance with the provisions of paragraphs 
(c), (e), (f) and (g) of Rule 144 promulgated under the Securities Act, or 
(iii) I am not at the time an affiliate of USBC and have been the beneficial 
owner of the Stock for at least one year (or such other period as may be 
prescribed by the Securities Act and the rules and regulations promulgated 
thereunder) and USBC has filed with the Commission all of the reports it is 
required to file under the Securities Exchange Act of 1934, as amended, 
during the preceding 12 months, or (iv) I am not and have not been for at 
least three months an affiliate of USBC and have been the beneficial owner of 
the Stock for at least two years (or such other period as may be prescribed 
by the Securities Act and the rules and regulations promulgated thereunder), 
or (v) USBC shall have received a letter from the staff of the Commission, or 
an opinion of counsel reasonably acceptable to USBC, to the effect that the 
stock transfer restrictions and the legend are not required.

          6.   I have carefully read this letter agreement and the Agreement 
and have discussed their requirements and other applicable limitations upon 
my ability to offer to sell, transfer or otherwise dispose of shares of the 
Stock, to the extent I felt necessary, with my counsel or counsel for Zappco.

                         Sincerely,



                         ----------------------------------------

                                  ESCROW AGREEMENT


          THIS ESCROW AGREEMENT is made and entered into this 12th day of 
September, 1997, by and among U.S. Bancorp ("USBC"), Zappco, Inc. ("Zappco") 
and First Trust National Association (the "Escrow Agent").

          Reference is made to that certain Agreement and Plan of Merger 
dated the date hereof (the "Merger Agreement") by and between USBC and 
Zappco. The Merger Agreement provides that USBC shall deposit in an escrow 
account with the Escrow Agent for the benefit of Zappco an aggregate of 
$1,500,000 (the "Escrow Funds"), of which $500,000 has previously been 
deposited in a demand deposit account (Account No. 173100380612) (the 
"Existing Escrow Account") with U.S. Bank National Association (d/b/a First 
Bank National Association) and upon the execution of this Escrow Agreement 
will be transferred to an escrow account (the "New Escrow Account") with the 
Escrow Agent.  Such Escrow Funds are to be held in escrow pursuant to the 
terms of the Merger Agreement. The parties hereto desire that the Escrow 
Agent hold, invest and distribute the Escrow Funds, together with interest 
accrued thereon, all in the manner set forth in this Escrow Agreement.

          NOW, THEREFORE, in consideration of the foregoing premises, the 
mutual covenants of the parties contained herein and in the Merger Agreement, 
and of other good and valuable consideration, the receipt and sufficiency of 
which is hereby acknowledged by each of the parties, it is agreed as follows:

          1.   DEFINITIONS.  Capitalized terms used and not defined herein 
shall have the meaning given them in the Merger Agreement.

          2.   APPOINTMENT OF ESCROW AGENT.  USBC and Zappco hereby appoint 
and designate the Escrow Agent as the escrow agent for the purposes set forth 
in this Escrow Agreement, and the Escrow Agent hereby accepts such 
appointment under the terms and conditions set forth herein.  This Escrow 
Agreement shall supersede any prior written or oral agreement of the parties 
with respect to the funds held in the Existing Escrow Account.

          3.   ESCROW DEPOSIT AND INVESTMENT.  Prior to the execution of this 
Escrow Agreement, USBC has deposited $500,000 of the Escrow Funds in the 
Existing Escrow Account.  Contemporaneous with the execution and delivery of 
this Escrow Agreement, such funds in the Existing Escrow Account have been 
transferred to the New Escrow Account and USBC has delivered $1,000,000 (the 
"Second Escrow Deposit") to the Escrow Agent for deposit in the New Escrow 
Account, which brings the aggregate amount deposited in the New Escrow 
Account to $1,500,000 (excluding earnings on deposits to date).  The Escrow 
Agent agrees to hold and invest such Escrow Funds, together with interest 
accrued thereon, in the manner set forth in Schedule A to this Escrow 
Agreement, until such funds, and the interest accrued thereon, are released 
in accordance with the provisions of Section 4 hereof.  The Escrow Agent 
shall change such investments procedures upon written instructions signed by 
USBC and Zappco.  The Escrow Agent shall have the right to liquidate any 
investments held in order to provide funds necessary to make required 
payments under this Escrow Agreement.  The Escrow Agent shall not be liable 
for any loss incurred at such liquidation which is due to fluctuations in 
market rates or penalties incurred because of early redemption.

                                          A-41
<PAGE>

          4.   RELEASE OF ESCROW FUNDS.  The Escrow Funds, and the interest 
accrued thereon, shall be released in accordance with written instructions 
signed by USBC and Zappco delivered to the Escrow Agent.  USBC and Zappco 
agree that Article 8 of the Merger Agreement shall govern the manner in which 
the Escrow Funds shall be released by the Escrow Agent and that their written 
instructions to the Escrow Agent shall be in accordance with such Article 8.

          5.   FEES OF ESCROW AGENT.  The Escrow Agent shall be entitled to a 
fee for its services in the amount set forth on Schedule B to this Escrow 
Agreement. Such fee shall be paid by USBC upon invoice from the Escrow Agent. 
If the Second Escrow Deposit is released to Zappco upon written request from 
USBC and Zappco, then the Escrow Agent shall deduct the entire fee from the 
interest and income earned from the investment and reinvestment of the Escrow 
Funds and shall reimburse USBC for its payment of the fee of the Escrow 
Agent. 

          6.   DUTY AND LIABILITY OF ESCROW AGENT. The sole duty of the 
Escrow Agent shall be to receive, hold and distribute the Escrow Funds as 
provided in this Escrow Agreement.  The Escrow Agent shall incur no liability 
with respect to any action taken by it in reliance upon or in response to any 
joint notice, direction, instruction or consent of the parties which may be 
given under the terms of this Escrow Agreement, nor for any action or 
omission of the Escrow Agent hereunder, except for its own willful 
misconduct.  The duties and responsibilities of the Escrow Agent shall be 
limited to those expressly set forth in this Escrow Agreement, and the Escrow 
Agent shall not be subject to nor bound by the terms of any other agreement 
between the parties.

          7.   ASSIGNMENT; BINDING EFFECT.  This Escrow Agreement shall 
extend to, shall inure to the benefit of and shall be binding upon all of the 
parties hereto and upon all of their respective successors and permitted 
assigns.  This Escrow Agreement shall not be assignable or transferable, in 
whole or in part, by any of the parties hereto except upon the express prior 
written consent of all of the other parties hereto, and nothing contained in 
this Escrow Agreement is intended to confer upon any person, other than the 
parties hereto and their respective successors and permitted assigns, any 
rights, remedies or obligations under, or by reason of, this Escrow Agreement.

          8.   NOTICES.  All notices and other communications hereunder shall

[Dain Bosworth Letterhead/Logo]



September 12, 1997



Board of Directors
Zappco, Inc.
1015 West St. Germain
St. Cloud, MN 56301

Members of the Board:

You have requested our opinion, as of the date hereof, as to the fairness, 
from a financial point of view, to the holders of the common stock of Zappco, 
Inc. (the "Company") of the consideration to be received by such holders in 
connection with an Agreement and Plan of Reorganization (the "Merger 
Agreement"), dated on or about September 12, 1997, by and among U.S. Bancorp 
("USB") and the Company.  The Merger Agreement provides for, among other 
things, the merger of the Company with and into USB (the "Merger") pursuant 
to which the holders of the common stock of Zappco will receive such number 
of shares of USB common stock as determined by dividing the amount of 
approximately $69,899,000, plus additional retained earnings from August 31, 
1997 to the closing of the Merger (the "Effective Time"), by the average 
closing price of USB's common stock for the ten trading days preceding the 
Effective Time.  A portion of the USB shares received by the holders of 
Zappco common stock will be restricted as to transferability for a period of 
two years following the Effective Time.

Dain Bosworth Incorporated ("Dain Bosworth"), as part of its investment 
banking business, is continually engaged in the valuation of businesses and 
their securities in connection with mergers and acquisitions, negotiated 
underwritings, competitive bids, secondary distributions of listed and 
unlisted securities, private placements, and valuations for estate, 
corporate, and other purposes.  In the ordinary course of business Dain 
Bosworth has published research reports and made recommendations regarding 
the equity securities of USB, as well as other companies in the commercial 
banking industry.  Additionally, Dain Bosworth has traded debt and equity 
securities of USB as well as the securities of other publicly traded 
companies in the commercial banking industry, and periodically may have 
positions in such securities.  Dain Bosworth has in the past served as a 
managing underwriter for public offerings of USB equity and debt securities, 
and has also acted as agent in the private placement of USB debt securities.

Dain Bosworth has been engaged by the Company to render this fairness opinion 
and we will receive a fee for rendering such opinion.  We also will be 
indemnified against certain liabilities that may arise from activities 
related to our engagement.

In connection with this opinion, we have, among other things, reviewed 
certain publicly available information regarding the Company and USB.  In 
addition, we have reviewed certain confidential financial, operating and 
other information supplied to us by the Company.  We visited the corporate 
offices of the Company and made inquiries of management regarding the past 
and current business operations, financial condition, and future prospects of 
the Company.  We have reviewed drafts of the Merger Agreement and drafts of 
selected other documents related to the Merger.  In addition, we have held 
discussions with the senior management of the Company and USB to understand 
their respective reasons for completing the Merger.

We have also considered certain publicly-available financial and stock market 
data on USB.  We compared this information to similar information for certain 
publicly traded companies in the business similar to the Company and USB, and 
we also considered, to the extent publicly available, the terms of selected 
relevant mergers and acquisitions, analyzed the general economic outlook for 
companies in the commercial banking industry, and performed other studies and 
analyses as we considered appropriate.

In conduction our review and in rendering our opinion, we have assumed and 
relied upon the accuracy and completeness of the financial and other 
information provided to us or publicly available, and we have not assumed any 
responsibility for independent verification of such information. It is 
understood that we were retained by the Board of Directors of the Company, 
and that the Board of Directors has not looked to us for independent 
verification with respect to the financial and other information provided to 
us or publicly available, including the projections provided to us relating 
to the Company.  We have further relied upon the assurances of management of 
the Company that they are not aware of any facts that would make the 
information supplied to us by the Company inaccurate or misleading.

Our opinion as expressed herein is limited to the fairness to common 
shareholders of the Company, from a financial point of view, of the 
consideration to be received by such shareholders in connection with the 
Merger, and does not address the Company's underlying business decision to 
proceed with the Merger.  We were not asked to solicit, and did not solicit, 
proposals from other parties regarding a merger or acquisition of the 
Company.  We did not make an independent appraisal of the assets or 
liabilities of the Company or USB, and we do not express an opinion regarding 
the liquidation value or solvency of either company or the regulatory 
compliance of USB.  Also, we are not expressing any opinion herein as to the 
prices at which the stock of USB will trade in the future.  Our opinion is 
based solely on information available to us on or before the date hereof, 
and reflects general market, economic, financial, monetary, and other conditions
as of such date.

This opinion does not constitute a recommendation to any shareholder of the 
Company as to how such shareholder should vote at the shareholders' meeting to 
be held in connection with the Merger.  Also, our opinion may not be reproduced,
quoted, published, or referred to in any manner, nor be used for any other 
purposes, without our prior written consent.

Based upon the foregoing, and other matters that we considered relevant, it 
is our opinion that, as of the date hereof, the consideration to be received 
by the common shareholders of the Company pursuant to the terms of the Merger 
is fair to such shareholders from a financial point of view.

Very truly yours,


/s/ DAIN BOSWORTH INCORPORATED

                          SECTIONS 302A.471 AND 302A.473 OF
                      THE MINNESOTA  BUSINESS CORPORATION ACT--
                             DISSENTERS' APPRAISAL RIGHTS
                                           
302A.471.  RIGHTS OF DISSENTING SHAREHOLDERS

    SUBDIVISION 1.  ACTIONS CREATING RIGHTS.  A shareholder of a corporation
may dissent from, and obtain payment for the fair value of the shareholder's
shares in the event of, any of the following corporate actions:

    (a)  An amendment of the articles that materially and adversely affects the
rights or preferences of the shares of the dissenting shareholder in that it:

         (1)  alters or abolishes a preferential right of the shares;

         (2)  creates, alters, or abolishes a right in respect of the
    redemption of the shares, including a provision respecting a sinking fund
    for the redemption or repurchase of the shares;

         (3)  alters or abolishes a preemptive right of the holder of the
    shares to acquire shares, securities other than shares, or rights to
    purchase shares or securities other than shares;

         (4)  excludes or limits the right of a shareholder to vote on a
    matter, or to cumulate votes, except as the right may be excluded or
    limited through the authorization or issuance of securities of an existing
    or new class or series with similar or different voting rights; except that
    an amendment to the articles of an issuing public corporation that provides
    that section 302A.671 does not apply to a control share acquisition does
    not give rise to the right to obtain payment under this section;

    (b)  A sale, lease, transfer, or other disposition of all or substantially
all of the property and assets of the corporation, but not including a
transaction permitted without shareholder approval in section 302A.661,
subdivision 1, or a disposition in dissolution described in section 302A.725,
subdivision 2, or a disposition pursuant to an order of a court, or a
disposition for cash on terms requiring that all or substantially all of the net
proceeds of disposition be distributed to the shareholders in accordance with
their respective interests within one year after the date of disposition;

    (c)  A plan of merger, whether under this chapter or under chapter 322B, to
which the corporation is a party, except as provided in subdivision 3;

    (d)  A plan of exchange, whether under this chapter or under chapter 322B,
to which the corporation is a party as the corporation whose shares will be
acquired by the acquiring corporation, if the shares of the shareholder are
entitled to be voted on the plan; or

    (e)  Any other corporate action taken pursuant to a shareholder vote with
respect to which the articles, the bylaws, or a resolution approved by the board
directs that dissenting shareholders may obtain payment for their shares.

    SUBD. 2.  BENEFICIAL OWNERS.  

    (a) A shareholder shall not assert dissenters' rights as to less than all
of the shares registered in the name of the shareholder, unless the shareholder
dissents with respect to all the shares that are

                                      C-1

<PAGE>

beneficially owned by another person but registered in the name of the 
shareholder and discloses the name and address of each beneficial owner on 
whose behalf the shareholder dissents.  In that event, the rights of the 
dissenter shall be determined as if the shares as to which the shareholder 
has dissented and the other shares were registered in the names of different 
shareholders.

    (b)  The beneficial owner of shares who is not the shareholder may assert
dissenters' rights with respect to shares held on behalf of the beneficial
owner, and shall be treated as a dissenting shareholder under the terms of this
section and section 302A.473, if the beneficial owner submits to the corporation
at the time of or before the assertion of the rights a written consent of the
shareholder.

    SUBD. 3  RIGHTS NOT TO APPLY.  

    (a)  Unless the articles, the bylaws, or a resolution approved by the board
otherwise provide, the right to obtain payment under this section does not apply
to a shareholder of the surviving corporation in a merger, if the shares of the
shareholder are not entitled to be voted on the merger.

    (b)  If a date is fixed according to section 302A.445, subdivision 1, for
the determination of shareholders entitled to receive notice of and to vote on
an action described in subdivision 1, only shareholders as of the date fixed,
and beneficial owners as of the date fixed who hold through shareholders, as
provided in subdivision 2, may exercise dissenters' rights.

    SUBD. 4.  OTHER RIGHTS.  The shareholders of a corporation who have a right
under this section to obtain payment for their shares do not have a right at law
or in equity to have a corporate action described in subdivision 1 set aside or
rescinded, except when the corporate action is fraudulent with regard to the
complaining shareholder or the corporation.

302A.473.  PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS

    SUBDIVISION 1.  DEFINITIONS.  

    (a)  For purposes of this section, the terms defined in this subdivision
have the meanings given them.

    (b)  "Corporation" means the issuer of the shares held by a dissenter
before the corporate action referred to in section 302A.471, subdivision 1 or
the successor by merger of that issuer.

    (c)  "Fair value of the shares" means the value of the shares of a
corporation immediately before the effective date of the corporate action
referred to in section 302A.471, subdivision 1.

    (d)  "Interest" means interest commencing five days after the effective
date of the corporate action referred to in section 302A.471, subdivision 1, up
to and including the date of payment, calculated at the rate provided in section
549.09 for interest on verdicts and judgments.

    SUBD. 2.  NOTICE OF ACTION.  If a corporation calls a shareholder meeting
at which any action described in section 302A.471, subdivision 1 is to be voted
upon, the notice of the meeting shall inform each shareholder of the right to
dissent and shall include a copy of section 302A.471 and this section and a
brief description of the procedure to be followed under these sections.

    SUBD. 3.  NOTICE OF DISSENT.  If the proposed action must be approved by
the shareholders, a shareholder who is entitled to dissent under section
302A.471 and who wishes to exercise dissenters' rights must file with the
corporation before the vote on the proposed action a written notice of intent to
demand the fair value of the shares owned by the shareholder and must not vote
the shares in favor of the proposed action.

                                      C-2

<PAGE>

    SUBD. 4.  NOTICE OF PROCEDURE; DEPOSIT OF SHARES.  

    (a)  After the proposed action has been approved by the board and, if
necessary, the shareholders, the corporation shall send to all shareholders who
have complied with subdivision 3 and to all shareholders entitled to dissent if
no shareholder vote was required, a notice that contains:

         (1)  The address to which a demand for payment and certificates of
    certificated shares must be sent in order to obtain payment and the date by
    which they must be received;

         (2)  Any restrictions on transfer of uncertificated shares that will
    apply after the demand for payment is received;

         (3)  A form to be used to certify the date on which the shareholder,
    or the beneficial owner on whose behalf the shareholder dissents, acquired
    the shares or an interest in them and to demand payment; and

         (4)  A copy of section 302A.471 and this section and a brief
    description of the procedures to be followed under these sections.

    (b)  In order to receive the fair value of the shares, a dissenting
shareholder must demand payment and deposit certificated shares or comply with
any restrictions on transfer of uncertificated shares within 30 days after the
notice required by paragraph (a) was given, but the dissenter retains all other
rights of a shareholder until the proposed action takes effect.

    SUBD. 5.  PAYMENT; RETURN OF SHARES.  

    (a)  After the corporate action takes effect, or after the corporation
receives a valid demand for payment, whichever is later, the corporation shall
remit to each dissenting shareholder who has complied with subdivisions 3 and 4
the amount the corporation estimates to be the fair value of the shares, plus
interest, accompanied by:

         (1)  The corporation's closing balance sheet and statement of income
    for a fiscal year ending not more than 16 months before the effective date
    of the corporate action, together with the latest available interim
    financial statements;

         (2)  An estimate by the corporation of the fair value of the shares
    and a brief description of the method used to reach the estimate; and

         (3)  A copy of section 302A.471 and this section, and a brief
    description of the procedure to be followed in demanding supplemental
    payment.

    (b)  The corporation may withhold the remittance described in paragraph (a)
from a person who was not a shareholder on the date the action dissented from
was first announced to the public or who is dissenting on behalf of a person who
was not a beneficial owner on that date.  If the dissenter has complied with
subdivisions 3 and 4, the corporation shall forward to the dissenter the
materials described in paragraph (a), a statement of the reason for withholding
the remittance, and an offer to pay to the dissenter the amount listed in the
materials if the dissenter agrees to accept that amount in full satisfaction. 
The dissenter may decline the offer and demand payment under subdivision 6. 
Failure to do so entitles the dissenter only to the amount offered.  If the
dissenter makes demand, subdivisions 7 and 8 apply.

    (c)  If the corporation fails to remit payment within 60 days of the
deposit of certificates or the imposition of transfer restrictions on
uncertificated shares, it shall return all deposited certificates

                                      C-3

<PAGE>

and cancel all transfer restrictions.  However, the corporation may again 
give notice under subdivision 4 and require deposit or restrict transfer at a 
later time.

    SUBD. 6.  SUPPLEMENTAL PAYMENT; DEMAND.  If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference.  Otherwise, a dissenter is entitled only to
the amount remitted by the corporation.

    SUBD. 7.  PETITION; DETERMINATION.  If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest.  The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located.  The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation.  The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
rules of civil procedure.  Nonresidents of this state may be served by
registered or certified mail or by publication as provided by law.  Except as
otherwise provided, the rules of civil procedure apply to this proceeding.  The
jurisdiction of the court is plenary and exclusive.  The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares.  The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter.  The fair value of the shares as determined by the court is binding
on all shareholders, wherever located.  A dissenter is entitled to judgment in
cash for the amount by which the fair value of the shares as determined by the
court, plus interest, exceeds the amount, if any, remitted under subdivision 5,
but shall not be liable to the corporation for the amount, if any, by which the
amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair
value of the shares as determined by the court, plus interest.

    SUBD. 8.  COSTS; FEES; EXPENSES.  

    (a)  The court shall determine the costs and expenses of a proceeding under
subdivision 7, including the reasonable expenses and compensation of any
appraisers appointed by the court, and shall assess those costs and expenses
against the corporation, except that the court may assess part or all of those
costs and expenses against a dissenter whose action in demanding payment under
subdivision 6 is found to be arbitrary, vexatious, or not in good faith.

    (b)  If the court finds that the corporation has failed to comply
substantially with this section, the court may assess all fees and expenses of
any experts or attorneys as the court deems equitable.  These fees and expenses
may also be assessed against a person who has acted arbitrarily, vexatiously, or
not in good faith in bringing the proceeding, and may be awarded to a party
injured by those actions.

    (c)  The court may award, in its discretion, fees and expenses to an
attorney for the dissenters out of the amount awarded to the dissenters, if any.
