                [LETTERHEAD OF FIRST NATIONAL BANK OF KERRVILLE]
 
                                                               November   , 1994
 
Dear Shareholder:
 
     You are cordially invited to attend the Special Meeting of Shareholders of
First National Bank of Kerrville (the "Bank") to be held at the main office of
the Bank, 301 Junction Highway, Kerrville, Texas, on             , November   ,
1994, at   :   .m., local time. At the Special Meeting you will be asked to
consider and vote on the approval of a proposed reorganization whereby a
national banking association which is a wholly owned subsidiary of Norwest
Corporation ("Norwest") will be consolidated with the Bank (the "Consolidation")
pursuant to the Amended and Restated Agreement and Plan of Reorganization, dated
as of July 8, 1994, between the Bank and Norwest (together with the Agreement
and Plan of Consolidation attached thereto, the "Consolidation Agreement").
 
     Under the terms of the Consolidation Agreement, the Consolidation will
result in the conversion of each share of the Bank's Common Stock outstanding
immediately prior to the time the Consolidation becomes effective into a number
of shares of Norwest Common Stock determined in accordance with the provisions
of the Consolidation Agreement, as described in the accompanying Proxy
Statement-Prospectus for the Special Meeting.
 
     The enclosed Proxy Statement-Prospectus contains a more complete
description of the terms of the Consolidation. You are urged to read the Proxy
Statement-Prospectus carefully.
 
     The Board of Directors has approved the Consolidation Agreement as being in
the best interest of the Bank's shareholders and recommends that you vote in
favor of the Consolidation. In making this recommendation, the Board of
Directors has considered numerous factors including the consideration offered by
Norwest and the structure of the proposed Consolidation, which is designed to
enhance the value of the investment of the Bank's shareholders and to be
tax-free for federal income tax purposes to the Bank's shareholders receiving
Norwest Common Stock. Vinson & Elkins, special tax counsel, is providing its
opinion to the Board of Directors that the Consolidation will be treated as a
tax-free reorganization for federal income tax purposes. However, you should
consult your own tax advisor concerning the federal, and any applicable foreign,
state, and local, income tax consequences to you of the Consolidation.
 
     In order to ensure that your vote is represented at the Special Meeting,
please date, sign, and promptly return your proxy in the enclosed envelope. If
you attend the meeting, you may vote in person if you wish, even though you have
previously returned your proxy.

     The following summary is not intended to be complete and is qualified in
all respects by the more detailed information included in this Proxy
Statement-Prospectus, the Appendices hereto, and the documents incorporated by
reference herein. As used in this Proxy Statement-Prospectus, the terms
"Norwest" and the "Bank" refer to such entities, respectively, and where the
context requires, such entities and their respective subsidiaries. All
information concerning Norwest included in this Proxy Statement-Prospectus has
been furnished by Norwest, and all information concerning the Bank included in
this Proxy Statement-Prospectus has been furnished by the Bank to Norwest for
incorporation herein.
 
THE COMPANIES
 
     Norwest Corporation
 
     Norwest Corporation is a regional bank holding company which was organized
under the laws of Delaware in 1929 and is registered under the Bank Holding
Company Act of 1956, as amended (the "BHC Act"). As a diversified financial
services organization, Norwest operates through subsidiaries engaged in banking
and in related businesses. Norwest provides retail, commercial, and corporate
banking services to its customers through banks located in Arizona, Colorado,
Illinois, Indiana, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota,
Ohio, South Dakota, Texas, Wisconsin, and Wyoming. Norwest provides additional
financial services to its customers through subsidiaries engaged in various
businesses, principally mortgage banking, consumer finance, equipment leasing,
agricultural finance, commercial finance, securities brokerage and investment
banking, insurance, computer and data processing services, trust services, and
venture capital investments.
 
     At June 30, 1994, Norwest had consolidated total assets of $55.8 billion,
total deposits of $34.7 billion, and total stockholders' equity of $3.8 billion.
Based on total assets at June 30, 1994, Norwest was the 13th largest commercial
banking organization in the United States.
 
     Norwest regularly explores opportunities for acquisitions of financial
institutions and related businesses. In connection with many of its completed
acquisitions, Norwest has issued its Common Stock to the shareholders of the
acquired entity and can be expected to continue to do so in the future.
Generally, management of Norwest does not make any public announcement about a
potential acquisition until a definitive agreement has been signed. Norwest has
entered into definitive agreements for the acquisition of various financial
institutions, including the Bank, having aggregate total assets at June 30,
1994, of approximately $3 billion. Certain of these acquisitions were completed
subsequent to June 30, 1994, and the others remain subject to regulatory
approval and are expected to be completed before the end of the first quarter of
1995. None of these acquisitions is significant to the financial statements of
Norwest, either individually or in the aggregate.
 
     Norwest's principal executive offices are located at Norwest Center, Sixth
and Marquette, in Minneapolis, Minnesota, and its telephone number is
612-667-1234.
 
     Additional information concerning Norwest is included in the Norwest
documents incorporated by reference herein. See "INCORPORATION OF CERTAIN
DOCUMENTS BY REFERENCE."
 
     First National Bank of Kerrville
 
     The Bank provides retail and commercial banking services to its customers
through three community banking offices, two offices being located in Kerrville,
Texas, and the third located in the adjacent town of Ingram. The Bank's deposits
are insured by the Bank Insurance Fund of the Federal Deposit Insurance
Corporation (the "FDIC"). At June 30, 1994, the Bank had total assets of $204.2
million, deposits of $187.0 million, and stockholders' equity of $16.7 million.
The Bank was chartered as a state bank in 1907 and converted to a national bank
in 1959.
 
     The Bank provides a wide range of banking services for its retail and
commercial customers, including real estate loans, revolving credit
arrangements, inventory and accounts receivable financing, equipment
 
                                        4

financing, home improvement and other personal loans, NOW checking, savings and
time accounts, and trust services. The Bank provides 24-hour access to routine
banking services through its automated teller machines.
 
     The Bank's headquarters are located at 301 Junction Highway in Kerrville,
Texas, and the Bank's phone number is 210-896-2424. See "INFORMATION ABOUT THE
BANK."
 
TERMS OF THE CONSOLIDATION
 
     The Consolidation Agreement provides for the consolidation of a wholly
owned banking subsidiary of Norwest with the Bank, under the charter of the
Bank. Upon consummation of the Consolidation, the outstanding shares of Bank
Common Stock (other than shares as to which statutory dissenters' rights have
been exercised and not forfeited) will be converted into a number of shares of
Norwest Common Stock determined in accordance with the provisions of the
Consolidation Agreement. As provided in the Consolidation Agreement, the exact
number of shares of Norwest Common Stock into which each share of Bank Common
Stock will be converted will be determined using a conversion factor calculated
by dividing 1,225,000 (subject to adjustment under certain specified
circumstances) by the number of shares of Bank Common Stock outstanding
immediately prior to the Consolidation. See "THE CONSOLIDATION -- Terms of the
Consolidation."
 
THE SPECIAL MEETING AND VOTE REQUIRED
 
     The Special Meeting
 
     The Special Meeting of Shareholders of the Bank to consider and vote on the
Consolidation will be held on             , November   , 1994, at   :  p.m.,
local time, at the main office of the Bank, 301 Junction Highway, Kerrville,
Texas. Only holders of record of Bank Common Stock at the close of business on
October   , 1994, will be entitled to notice of and to vote at the Special
Meeting. At such date, there were 25,000 shares of Bank Common Stock
outstanding. Each share of Bank Common Stock is entitled to one vote. For
additional information relating to the Special Meeting, see "MEETING
INFORMATION."
 
     Vote Required
 
     Approval of the Consolidation Agreement requires the affirmative vote of
the holders of two-thirds of the outstanding shares of Bank Common Stock. See
"MEETING INFORMATION -- Record Date; Vote Required."
 
     As of the record date for the Special Meeting, directors and officers of
the Bank owned beneficially or controlled the voting of 100% of the shares of
Bank Common Stock outstanding on that date. The Bank's directors and officers
have informed the Bank that they intend to vote all of their shares in favor of
the Consolidation. At the record date, directors and executive officers of
Norwest did not own beneficially any shares of Bank Common Stock. See "MEETING
INFORMATION -- Record Date; Vote Required" and "MEETING INFORMATION -- Principal
Shareholders and Security Ownership of Management."
 
REASONS FOR THE CONSOLIDATION
 
     The Board of Directors of the Bank has concluded that the Consolidation is
in the best interest of the holders of Bank Common Stock, who will receive, in a
tax-free exchange, stock of a much larger and more diversified enterprise that
is actively traded on national stock exchanges. In addition to the greater
liquidity provided to the Bank's shareholders, the Consolidation will provide
customers of the Bank with access to a broader range of services and will
provide the Bank with increased financial strength. See "THE CONSOLIDATION --
Background of and Reasons for the Consolidation."
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF THE BANK
 
     THE BOARD OF DIRECTORS OF THE BANK UNANIMOUSLY RECOMMENDS THAT THE BANK
SHAREHOLDERS VOTE FOR THE CONSOLIDATION. For information concerning the
 
                                        5
<PAGE>   10
 
interests of certain members of the Bank's Board of Directors and management in
the Consolidation, see "THE CONSOLIDATION -- Interests of Certain Persons in the
Consolidation."
 
EFFECTIVE DATE AND TIME OF THE CONSOLIDATION
 
     Subject to the terms and conditions of the Consolidation Agreement, the
Consolidation will be effective at 11:59 p.m., Minneapolis, Minnesota time, (the
"Effective Time of the Consolidation") on the date specified in the certificate
of approval to be issued by the Office of the Comptroller of the Currency. See
"THE CONSOLIDATION -- Effective Date and Time of the Consolidation" and "THE
CONSOLIDATION -- Conditions to the Consolidation."
 
CONDITIONS AND TERMINATION
 
     The respective obligations of Norwest and the Bank to consummate the
Consolidation are subject to certain conditions, including the receipt of
regulatory approvals without unduly burdensome conditions, approval of the
Consolidation Agreement by the shareholders of the Bank, receipt by the Bank of
certain tax opinions, and certain other conditions customary in transactions of
this nature. See "THE CONSOLIDATION -- Conditions to the Consolidation" and "THE
CONSOLIDATION -- Regulatory Approvals."
 
     The Consolidation Agreement may be terminated at any time prior to the
Effective Date of the Consolidation, whether prior to or after approval by the
Bank's shareholders, by either party under specified conditions, including if
the Consolidation shall not have been consummated by December 31, 1994, unless
such failure of consummation shall be due to the failure of the party seeking
termination to perform its respective covenants and agreements under the
Consolidation Agreement. See "THE CONSOLIDATION -- Waiver, Amendment, and
Termination."
 
ACCOUNTING TREATMENT
 
     Management of Norwest anticipates that the Consolidation will be accounted
for as a purchase under generally accepted accounting principles. See "THE
CONSOLIDATION -- Accounting Treatment."
 
REGULATORY APPROVALS
 
     The Consolidation is subject to the approval of the Board of Governors of
the Federal Reserve System (the "Federal Reserve Board") and also the approval
of the Office of the Comptroller of the Currency (the "OCC"). Both such
approvals have been received. See "THE CONSOLIDATION -- Regulatory Approvals."
 
MANAGEMENT AND OPERATIONS AFTER THE CONSOLIDATION
 
     Following the Consolidation, Norwest intends to operate at the Bank's
present locations and to offer products and services offered by Norwest
affiliates. See "THE CONSOLIDATION -- Management and Operations After the
Consolidation."
 
INTERESTS OF CERTAIN PERSONS IN THE CONSOLIDATION
 
     Certain officers and directors of the Bank have direct and indirect
interests in the consummation of the Consolidation separate from their interests
as holders of Bank Common Stock. See "THE CONSOLIDATION -- Interests of Certain
Persons in the Consolidation."
 
DISSENTERS' RIGHTS
 
     Under federal law dissenting shareholders who comply with the requisite
statutory procedures will be entitled to receive an appraised value of their
shares. The value so determined could be more than, the same as, or less than
the value of the consideration to be received by Bank shareholders, pursuant to
the Consolidation Agreement, who do not dissent. See "THE CONSOLIDATION --
Rights of Dissenting Bank Shareholders."
 
                                        6
<PAGE>   11
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The Consolidation is designed so that no gain or loss (other than with
respect to cash received in lieu of fractional shares or in satisfaction of
dissenters' rights) will be recognized to Bank shareholders upon the exchange of
their Bank Common Stock for Norwest Common Stock. The opinion of Vinson &
Elkins, counsel for the Bank, with respect to the Consolidation qualifying as a
"tax-free" reorganization for federal income tax purposes will be provided to
the Bank. See "THE CONSOLIDATION -- Certain Federal Income Tax Considerations."
HOWEVER, THE FEDERAL INCOME TAX CONSIDERATIONS RELATED TO THE CONSOLIDATION MAY
BE DIFFERENT TO PARTICULAR TYPES OF BANK SHAREHOLDERS, OR IN LIGHT OF THE BANK
SHAREHOLDERS' PERSONAL INVESTMENT CIRCUMSTANCES. ACCORDINGLY, SHAREHOLDERS ARE
URGED TO CONSULT THEIR OWN TAX ADVISORS IN DETERMINING THE TAX CONSIDERATIONS
THAT MAY BE RELEVANT TO THEM IN CONNECTION WITH THE CONSOLIDATION UNDER FEDERAL,
STATE, LOCAL, AND ANY OTHER APPLICABLE TAX LAWS.
 
MARKETS AND MARKET PRICES
 
     Norwest Common Stock is listed on the New York Stock Exchange (the "NYSE")
and the Chicago Stock Exchange (the "CHX"). On May 19, 1994, the last trading
day preceding public announcement of the proposed Consolidation, the closing
price per share of Norwest Common Stock was $26.125 and on October   , 1994, the
price was $     . There is no public market for Bank Common Stock. Shareholders
of the Bank are advised to obtain current market quotations for Norwest Common
Stock. The market price for Norwest Common Stock will fluctuate between the date
of this Proxy Statement-Prospectus and the Effective Date of the Consolidation,
which may be a period of several weeks. As a result, the market value of the
Norwest Common Stock that shareholders of the Bank ultimately receive in the
Consolidation could be more or less than its market value on the date of this
Proxy Statement-Prospectus. No assurance can be given concerning the market
price of Norwest Common Stock before or after the Effective Date of the
Consolidation.
 
CERTAIN DIFFERENCES IN RIGHTS OF SHAREHOLDERS
 
     Upon consummation of the Consolidation, shareholders of the Bank will
become stockholders of Norwest. As a result, such shareholders' rights will
change significantly. See "THE CONSOLIDATION -- Certain Differences in Rights of
Shareholders."
 
COMPARATIVE UNAUDITED PER SHARE DATA
 
     The following table presents selected comparative unaudited per share data
for Norwest Common Stock on a historical and pro forma combined basis and for
Bank Common Stock on a historical and a pro forma equivalent basis giving effect
to the Consolidation using the purchase method of accounting. See "THE
CONSOLIDATION -- Accounting Treatment." This information is derived from the
consolidated historical financial statements of Norwest, including the related
notes thereto, incorporated by reference into this Proxy Statement-Prospectus
and the consolidated historical financial statements of the Bank, including the
notes thereto, appearing elsewhere in this Proxy Statement-Prospectus. This
information should be read in conjunction with such consolidated historical
financial statements and the related notes thereto. See "INCORPORATION OF
CERTAIN DOCUMENTS BY REFERENCE" and "FINANCIAL STATEMENTS OF THE BANK."
 
     This data is not necessarily indicative of the results of the future
operations of the combined entity or the actual results that would have occurred
had the Consolidation been consummated prior to the periods indicated.

- -------------------------
(1)  The pro forma combined book values per share of Norwest Common Stock are
     based upon the historical total common equity for Norwest and the Bank
     divided by total pro forma common shares of the combined entities assuming
     conversion of the outstanding Bank Common Stock at a conversion factor of
     49.0. The difference between the historical total common equity of the Bank
     and the total market value of Norwest Common Stock to be issued in the
     Consolidation is not material. The pro forma equivalent book values per
     share of Bank Common Stock represent the pro forma combined amounts
     multiplied by the assumed conversion factor. The assumed conversion factor
     used in this table is based on an assumed aggregate number of shares of
     Norwest Common Stock to be issued in the Consolidation of 1,225,000 upon
     conversion of all outstanding shares of Bank Common Stock and does not
     reflect possible adjustments for the Phoenix Matter described under "THE
     CONSOLIDATION -- Terms of the Consolidation."
 
(2)  Assumes no changes in cash dividends per share. The pro forma equivalent
     dividends per share of Bank Common Stock represent cash dividends declared
     per share of Norwest Common Stock multiplied by 49.0.
 
(3)  The pro forma combined net income per share (based on fully diluted net
     income and weighted average shares outstanding) is based upon the combined
     historical net income for Norwest and the Bank divided by the average pro
     forma common shares of the combined entities, assuming a conversion factor
     of 49.0. The pro forma equivalent net income per share of Bank Common Stock
     represents the pro forma combined net income per share multiplied by 49.0.

SELECTED FINANCIAL DATA
 
     The following table sets forth certain selected historical consolidated
financial information for Norwest and the Bank. The income statement and balance
sheet data included in the selected financial data for the five years ended
December 31, 1993, are derived from audited consolidated financial statements of
Norwest and the Bank for such five-year period. The selected financial data for
the six-month periods ended June 30, 1994 and 1993, are derived from the
unaudited historical financial statements of Norwest and the Bank. All financial
information derived from unaudited financial statements reflects, in the
respective opinions of management of Norwest and the Bank, all adjustments
(consisting only of normal recurring adjustments) necessary for a fair
presentation of such data. Results for the six months ended June 30, 1994, are
not necessarily indicative of the results that may be expected for any other
interim period or for the year as a whole. This information should be read in
conjunction with the consolidated financial statements of Norwest and the
related notes thereto, included in documents incorporated herein by reference,
and in conjunction with the consolidated financial statements of the Bank,
including the notes thereto, appearing elsewhere in this Proxy
Statement-Prospectus. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" and

(1) On January 14, 1994, First United Bank Group, Inc. ("First United"), a $3.9
    billion bank holding company headquartered in Albuquerque, New Mexico, was
    acquired in a pooling transaction. Norwest's historical results have been
    restated to include the historical results of First United. Appropriate
    Norwest items reflect an increase in First United's provision for credit
    losses of $16.5 million to conform with Norwest's credit loss reserve
    practices and methods and $83.2 million in accruals and reserves for
    merger-related expenses, including termination costs, systems and operations
    costs, and investment banking, legal, and accounting expenses.
 
(2) On February 9, 1993, Lincoln Financial Corporation ("Lincoln"), a $2.0
    billion bank holding company headquartered in Fort Wayne, Indiana, was
    acquired in a pooling transaction. Norwest's historical results have been
    restated to include the historical results of Lincoln. Appropriate Norwest
    items reflect an increase in Lincoln's provision for credit losses of $60.0
    million and $33.5 million in Lincoln's provisions and expenditures for costs
    related to restructuring activities.
 
(3) On April 19, 1991, United Banks of Colorado, Inc. ("United"), a $5.5 billion
    financial institution headquartered in Denver, Colorado, merged with Norwest
    in a pooling transaction. Norwest's historical results have been restated to
    include the historical results of United. Appropriate Norwest items reflect
    United's special provisions for credit losses and writedowns for other real
    estate owned, which together totaled $165 million, and $31 million of
    accruals for expected reorganization and restructuring costs for the year
    ended December 31, 1990. The special provisions were due to deterioration of
    several large commercial loan relationships, the anticipated results of the
    then recent examination by the Office of the Comptroller of the Currency,
    and the anticipated impact of the Resolution Trust Corporation's accelerated
    efforts to liquidate foreclosed properties at deep discounts.
 
(4) On May 1, 1990, First Interstate Corporation of Wisconsin ("FIWI"), a $2.0
    billion financial institution headquartered in Cheboygan, Wisconsin, merged
    with Norwest in a pooling transaction. Norwest's historical results have
    been restated to include the historical results of FIWI. Appropriate Norwest
    items reflect $12.0 million in charges resulting from FIWI's decision to
    sell its portfolio of stripped mortgage-backed securities, an increase in
    FIWI's provision for credit losses of $16.2 million, and $24.5 million in
    FIWI's provisions and expenditures for costs related to restructuring
    activities.

of the Consolidation Agreement. Any proxy given pursuant to this solicitation
may be revoked by the person giving it at any time before the proxy is voted by
filing either an instrument revoking it or a duly executed proxy bearing a later
date with the Secretary of the Bank prior to or at the Special Meeting or by
voting the shares subject to the proxy in person at the Special Meeting.
Attendance at the Special Meeting will not in and of itself constitute a
revocation of a proxy.

     A proxy may indicate that all or a portion of the shares represented
thereby are not being voted with respect to a specific proposal. This could
occur, for example, when a broker is not permitted to vote shares held in street
name on certain proposals in the absence of instructions from the beneficial
owner. Shares that are not voted with respect to a specific proposal will be
considered as not present for such proposal, even though such shares will be
considered present for purposes of determining a quorum and voting on other
proposals. Abstentions on a specific proposal will be considered as present, but
not as voting in favor of such proposal. The proposal to adopt the Consolidation
Agreement must be approved by the holders of two-thirds of the outstanding Bank
Common Stock. Because this proposal requires the affirmative vote of a specified
percentage of outstanding shares, the nonvoting of shares or abstentions with
regard to this proposal will have the same effect as votes against the proposal.
 
     The Board of Directors of the Bank is not aware of any business to be acted
upon at the Special Meeting other than the business described herein. If,
however, other matters are properly brought before the Special Meeting, or any
adjournments thereof, the persons appointed as proxies will have discretion to
vote or act on such matters according to their best judgment.
 
SOLICITATION OF PROXIES
 
     In addition to solicitation by mail, directors, officers, and employees of
the Bank may solicit proxies from the shareholders of the Bank, either
personally or by telephone, telegram, or other form of communication. None of
the foregoing persons who solicit proxies will be specifically compensated for
such services. Nominees, fiduciaries, and other custodians will be requested to
forward soliciting materials to beneficial owners and will be reimbursed for
their reasonable expenses incurred in sending proxy material to beneficial
owners. The Bank will bear its own expenses in connection with the solicitation
of proxies for the Special Meeting. See "THE CONSOLIDATION -- Expenses."
 
HOLDERS OF BANK COMMON STOCK ARE REQUESTED TO COMPLETE, DATE, AND SIGN THE
ACCOMPANYING PROXY AND RETURN IT PROMPTLY TO THE BANK IN THE ENCLOSED
POSTAGE-PREPAID ENVELOPE.
 
                               THE CONSOLIDATION
 
     This section of the Proxy Statement-Prospectus describes certain aspects of
the Consolidation. The following description does not purport to be complete and
is qualified in its entirety by reference to the Consolidation Agreement, which
is attached as Appendix A to this Proxy Statement-Prospectus and is incorporated
by reference herein. ALL SHAREHOLDERS OF THE BANK ARE URGED TO READ THE
CONSOLIDATION AGREEMENT IN ITS ENTIRETY.
 
BACKGROUND OF AND REASONS FOR THE CONSOLIDATION
 
     During the early part of 1994, the management of the Bank, Messrs. Griffin
and Goertz, received a number of inquiries from both state and national banking
organizations regarding a possible acquisition of the Bank. After preliminary
discussions and the exchange of financial and other information, these
discussions were terminated.
 
     During the first week of March, management of the Bank was contacted by
representatives of Norwest expressing an interest in having discussions.
Representatives of Norwest and management of the Bank met at the Bank's offices
on March 18, 1994, at which time Norwest discussed its plans to continue to
expand in the Texas banking market. During the next several weeks, the parties
exchanged and reviewed information and then met again at Norwest's offices in
Minneapolis on April 11 and April 12, 1994. At the conclusion of these meetings,
the parties agreed to proceed toward a letter of intent, which was approved by
the Board of Directors of the Bank on April 22, 1994. During the next several
weeks, Norwest completed its due diligence of the Bank, and the parties
negotiated a definitive agreement which was approved by the Board of Directors
of the Bank and executed by Norwest and the Bank on May 20, 1994. Effective as
of July 8, 1994, the definitive agreement was amended and restated.
 
                                       14
<PAGE>   19
 
     The management shareholders of the Bank were interested in achieving
liquidity in their investment and also enhancing the Bank's ability to become a
part of a larger and more diverse banking organization thereby enabling the Bank
to offer a broader range of services to its customers. Management of the Bank
believes that Norwest's continued expansion in the Texas banking market through
its acquisition of the Bank will result in the Bank becoming another example of
a sound and attractive banking operation for Norwest and enable Norwest to
acquire other banking operations in the state. Accordingly, the shareholders of
the Bank will be able to exchange their shares of the Bank for the stock of
Norwest which is actively traded on the New York and Chicago Stock Exchanges,
and its customers will benefit from the added financial strength and services
that Norwest can bring to the Bank.
 
     THE BOARD OF DIRECTORS OF THE BANK UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS
OF THE BANK VOTE FOR APPROVAL OF THE CONSOLIDATION AGREEMENT.
 
TERMS OF THE CONSOLIDATION
 
     At the Effective Time of the Consolidation, a wholly owned banking
subsidiary of Norwest, to be known as Norwest Interim Bank Kerrville, National
Association ("Norwest Interim Bank"), will consolidate with the Bank, under the
charter of the Bank. The Articles of Association and the By-Laws of the Bank in
effect at the Effective Time of the Consolidation will govern the surviving bank
until amended or repealed in accordance with applicable law. At the Effective
Time of the Consolidation, each outstanding share of Bank Common Stock (other
than shares as to which statutory dissenters' appraisal rights have been
exercised and not forfeited) will be converted into a number of shares of
Norwest Common Stock determined by dividing the Norwest Shares by the number of
shares of Bank Common Stock then outstanding. The "Norwest Shares" is 1,225,000,
reduced by the amount determined by dividing (i) the Adjustment Amount by (ii)
the Norwest Measurement Price. The "Adjustment Amount" is an amount to be
determined by (i) adding together all amounts which immediately prior to the
Effective Time of the Consolidation the Bank has paid and is obligated to pay on
account of a judgment entered against the Bank (the "Phoenix Matter"), including
the amount of the judgment or settlement, accrued interest thereon, costs
assessed, and attorneys fees of either party to the Phoenix Matter, and then
(ii) multiplying the result by 63.375%. In the lawsuit underlying the Phoenix
Matter, the plaintiffs obtained a judgment against a former director of the Bank
and certain other defendants. The Bank became involved in the Phoenix Matter
when it failed to respond to a writ of garnishment served on it by the
plaintiffs, who then obtained a default judgment against the Bank. The Bank has
filed a motion to vacate the default judgment, which as of the date of this
Proxy Statement-Prospectus is approximately $     million. The "Norwest
Measurement Price" is the average of the closing prices of a share of Norwest
Common Stock as reported on the consolidated tape of the New York Stock Exchange
during the period of five (5) trading days ending at the end of the third
trading day immediately preceding the Closing Date (as defined below). If the
Phoenix matter has not been finally resolved by the Closing Date, then a number
of shares equal to 1,225,000 less the Norwest Shares shall be deposited into
escrow in accordance with the terms of an escrow agreement to be entered into by
the parties after the date hereof (the "Escrow Agreement"). The Escrow Agreement
shall provide that shares held in escrow shall be distributed proportionately to
Norwest and the shareholders of the Bank based on amounts paid by the Bank to
resolve the Phoenix Matter and shall provide further that if the Phoenix Matter
is not finally resolved within 42 months after the Closing Date, such shares
shall be distributed to Norwest.
 
     The market price for Norwest Common Stock, and accordingly, the Norwest
Measurement Price, will fluctuate between the date of this Proxy
Statement-Prospectus and the Effective Date of the Consolidation, which may be a
period of several weeks. As a result, the market value of the Norwest Common
Stock that shareholders of the Bank ultimately receive in the Consolidation
could be more or less than its market value on the date of this Proxy
Statement-Prospectus.
 
     The Consolidation Agreement provides that if, between the date of the
Consolidation Agreement and the Effective Time of the Consolidation, shares of
Norwest 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
 
                                       15
<PAGE>   20
 
readjustment, or if a stock dividend thereon is declared with a record date
within the same period, the conversion ratios provided for in the Consolidation
Agreement will be adjusted accordingly.
 
     No fractional shares of Norwest Common Stock will be issued in the
Consolidation. Instead, Norwest will pay to each holder of Bank Common Stock who
would otherwise be entitled to a fractional share an amount of cash equal to the
fraction of a share of Norwest Common Stock to which the Bank shareholder would
otherwise be entitled multiplied by the average of the closing prices of a share
of Norwest Common Stock on the New York Stock Exchange for each of the five
trading days immediately preceding the Effective Time of the Consolidation.
 
     Shares of Norwest Common Stock issued and outstanding immediately prior to
the effective date of the Consolidation will remain issued and outstanding.
 
     Based upon the number of shares of Norwest Common Stock outstanding at June
30, 1994, approximately 316,682,227 shares of Norwest Common Stock would be
outstanding immediately following the Effective Time of the Consolidation, of
which less than 1% would be held by the former stockholders of the Bank.
 
EFFECTIVE DATE AND TIME OF THE CONSOLIDATION
 
     The Effective Time of the Consolidation will be 11:59 p.m., Minneapolis,
Minnesota time, on the Effective Date of the Consolidation, the date specified
in the certificate of approval to be issued by the OCC approving the
Consolidation. Subject to the terms and conditions set forth in the
Consolidation Agreement, the closing of the Consolidation will occur on a date
(the "Closing Date") agreed to by the parties to the Consolidation, but no later
than ten business days following the satisfaction or waiver of all conditions
set forth in the Consolidation Agreement, or on such other date upon which the
parties agree. The parties have agreed to hold the closing as soon as
practicable after approval of the Consolidation by the shareholders of the Bank.
Norwest and the Bank anticipate that the Consolidation will close in the fourth
quarter of 1994, although there can be no assurance as to whether or when the
Consolidation will occur. See "Terms of the Consolidation," "Conditions to the
Consolidation," and "Regulatory Approvals."
 
SURRENDER OF CERTIFICATES
 
     As soon as practicable after the Effective Time of the Consolidation,
Norwest Bank Minnesota, National Association, acting in the capacity of exchange
agent for Norwest (the "Exchange Agent"), will mail to each former holder of
record of shares of Bank Common Stock a form of letter of transmittal, together
with instructions for the exchange of such holder's Bank Common Stock
certificates for a certificate representing Norwest Common Stock.
 
     SHAREHOLDERS OF THE BANK SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY
RECEIVE THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS.
 
     Upon surrender to the Exchange Agent of one or more certificates for Bank
Common Stock, together with a properly completed letter of transmittal, there
will be issued and mailed to the holder a certificate representing the number of
whole shares of Norwest Common Stock to which such holder is entitled and, where
applicable, a check for the amount representing any fractional share. A
certificate for Norwest Common Stock may be issued in a name other than the name
in which the surrendered certificate is registered only if (i) the certificate
surrendered is properly endorsed and otherwise in proper form for transfer and
(ii) the person requesting the issuance of such certificate either pays to the
Exchange Agent any transfer or other taxes required by reason of the issuance of
a certificate for such shares in a name other than the registered holder of the
certificate surrendered or establishes to the satisfaction of the Exchange Agent
that such tax has been paid or is not applicable.
 
     All Norwest Common Stock issued pursuant to the Consolidation will be
deemed issued as of the Effective Time of the Consolidation. No dividends on
Norwest Common Stock with a record date after the Effective Time of the
Consolidation will be paid to Bank shareholders entitled to receive certificates
for shares of Norwest Common Stock until such shareholders surrender their
certificates representing shares of Bank
 
                                       16
<PAGE>   21
 
Common Stock. Upon such surrender, there shall be paid to the shareholder in
whose name the certificates representing such shares of Norwest Common Stock are
issued any dividends the record and payment dates of which shall have been after
the Effective Time of the Consolidation and before the date of such surrender.
After such surrender, there shall be paid to the person in whose name the
certificate representing such shares of Norwest Common Stock is issued, on the
appropriate dividend payment date, any dividend on such shares of Norwest Common
Stock which shall have a record date after the Effective Time of the
Consolidation and prior to the date of surrender, but a payment date subsequent
to the surrender. In no event shall the persons entitled to receive such
dividends be entitled to receive interest on amounts payable as dividends.
 
CONDITIONS TO THE CONSOLIDATION
 
     The Consolidation will occur only if the Consolidation Agreement is
approved by the requisite vote of shareholders of the Bank. Consummation of the
Consolidation is subject to the satisfaction of certain other conditions, which
may be waived by the parties to the Consolidation Agreement, to the extent that
waiver is permitted by applicable law. Such conditions to the obligations of
both parties to consummate the Consolidation include (i) the continued accuracy
of representations and warranties by the other party, (ii) the performance by
the other party of its obligations under the Consolidation Agreement, (iii) the
receipt of certain certificates from officers of the other party, (iv) the
receipt of all necessary regulatory approvals, including the approval of the
Consolidation by the Federal Reserve Board, and the expiration of all applicable

of competent jurisdiction restraining, enjoining, or otherwise prohibiting
consummation of the transactions contemplated by the Consolidation Agreement,
(vi) the continued effectiveness of the Registration Statement of which this

securities law or blue sky authorizations necessary for the Consolidation, and
(vii) the receipt of a certificate signed by the other party's Chief Executive
Officer and Chief Financial Officer concerning the accuracy and completeness of
certain of party's financial statements and related information and the absence
of any changes in such financial statements and related information subsequent
to the date of such financial statements.
 
     The Bank's obligation to consummate the Consolidation is also subject to
(i) authorization for listing on the NYSE and CHX upon official notice of
issuance of the shares of Norwest Common Stock issuable pursuant to the
Consolidation and (ii) the receipt of an opinion of counsel for the Bank to the
effect that for federal income tax purposes the Consolidation will be a tax-free
reorganization.
 
     Norwest's obligation to consummate the Consolidation is also subject to (i)
the receipt by the Bank and its subsidiaries of any and all material consents or

and subject to issuance upon exercise of all warrants, options, conversion

the absence of any reasonable basis for any proceeding, claim, or action seeking
to impose, or that could reasonably be expected to result in the imposition, on
the Bank or any of its subsidiaries or their respective properties, of any
liability arising from the release of hazardous substances under any local,
state, or federal environmental statute, regulation, or ordinance which has had
or could reasonably be expected to have a material adverse effect upon the Bank
and its subsidiaries taken as a whole; and (vi) the absence of any change or
circumstance which has had or might reasonably be expected to have a material
adverse effect on the financial condition, results of operations, business, or
prospects of the Bank and its subsidiaries taken as a whole (other than changes
in banking laws or regulations that affect the banking industry generally or
changes in the general level of interest rates).

REGULATORY APPROVALS
 
     Transactions such as the Consolidation are subject to prior approval by the
Federal Reserve Board under the Bank Holding Company Act of 1956, as amended
(the "BHC Act"), which requires that the Federal Reserve Board 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. Transactions such as the Consolidation are also
subject to prior approval by the OCC under the National Bank Act. By letter
dated September 6, 1994, the Federal Reserve Board informed Norwest that it had
approved the Consolidation, and, by letter dated September 2, 1994, the OCC
informed Norwest that it had approved the Consolidation. In addition, as
required by Texas law, by letter dated September 7, 1994, Norwest notified the
Texas Department of Banking of its intent to make an interstate acquisition and
in connection therewith provided certain information and made certain
undertakings to the Texas Department of Banking.
 
     The approval of any application merely implies satisfaction of regulatory
criteria for approval, which do not include review of the transaction from the
standpoint of the adequacy of the consideration to be received by, or fairness
to, shareholders. Regulatory approvals do not constitute an endorsement or
recommendation of the proposed transactions.
 
     Norwest and the Bank are not aware of any additional governmental approvals
or compliance with banking laws and regulations that would be required for
consummation of the Consolidation other than those described above. Should any
other approval or action be required, it is currently contemplated that such
approval or action would be sought. There can be no assurance that any such
approval or action, if needed, could be obtained and, if such approvals or
actions are obtained, there can be no assurance regarding the timing thereof.
 
BUSINESS PENDING THE CONSOLIDATION
 
     Under the Consolidation Agreement, each of the Bank and its subsidiaries is
generally obligated to maintain its corporate existence in good standing; to
maintain the general character of its business and to conduct its business in
the ordinary and usual manner; to extend credit in accordance with existing
lending policies, except that it shall not, without the prior written consent of
Norwest, and each such consent shall be deemed to have been given if Norwest has
not responded to a request for such consent within three (3) business days of
receiving such request, (i) make any new loan to a nonborrower of the Bank in
excess of $500,000, or (ii) make any new loan or modify, restructure, or renew
any existing loan in excess of $200,000 (except pursuant to commitments made
prior to the date of this Agreement) to a present customer of the Bank if the
amount of the resulting loan, when aggregated with all other loans or extensions
of credit to such person, would exceed $500,000; to maintain proper business and
accounting records in accordance with generally accepted accounting principles;
to maintain its properties in good repair and condition, ordinary wear and tear
excepted; to maintain in all material respects presently existing insurance
coverage; to use its best efforts to preserve its business organization intact,
to keep the services of its present principal employees and to preserve its
goodwill and the goodwill of its suppliers, customers, and others having
business relationships with it; to use its best efforts to obtain any approvals
or consents required to maintain existing leases and other contracts in effect
following the Consolidation; to comply in all material respects with all laws,
regulations, ordinances, codes, orders, licenses, and permits applicable to its
properties and operations the noncompliance with which reasonably could be
expected to have a material adverse effect on the Bank and its subsidiaries
taken as a whole; and to permit Norwest and its representatives to examine its
books, records, and properties, and to interview officers, employees, and agents
at all reasonable times when it is open for business. The Consolidation
Agreement also provides that, prior to the Effective Time of the Consolidation,
the Bank may not, without the prior written consent of Norwest, among other
things: (i) amend or otherwise change its articles of incorporation or
association or bylaws; (ii) issue or sell, or authorize for issuance or sale, or
grant any options or make other agreements with respect to the issuance or sale,
or conversion, of any shares of its capital stock, phantom shares, or other
share equivalents, or any other of its securities; (iii) authorize or incur any
long-term debt (other than deposit liabilities); (iv) mortgage, pledge, or
subject to lien or other encumbrance any of its properties, except in the
ordinary course of business; (v) enter into any material agreement, contract, or
commitment in excess of $10,000 except banking transactions in the ordinary
course of
 
                                       18
<PAGE>   23
 
business and in accordance with policies and procedures in effect on the date of
the Consolidation Agreement; (vi) make any investments except individual
investments made in the ordinary course of business for terms of up to one year
and in amounts of $100,000 or less; (vii) make any contributions to any
"employee benefit plans" within the meaning of the Employee Retirement Income
Security Act of 1974, as amended, except as required by the terms of such plan
in effect as of the date of the Consolidation Agreement; (viii) declare, set
aside, make, or pay any dividend or other distribution with respect to its
capital stock except any dividend declared by a subsidiary in accordance with
applicable law; (ix) redeem, purchase, or otherwise acquire, directly or
indirectly, any of the capital stock of the Bank; (x) increase the compensation
of any officers, directors, or executive employees, except pursuant to existing
compensation plans and practices; (xi) sell or otherwise dispose of any shares
of the capital stock of any subsidiary; or (xii) sell or otherwise dispose of
any of its assets or properties other than in the ordinary course of business.
 
     Neither the Bank nor any director, officer, representative, or agent will
directly or indirectly, solicit, authorize the solicitation of, or enter into
any discussions with any corporation, partnership, person, or other entity or
group (other than Norwest) concerning any offer or possible offer (i) to
purchase any shares of common stock, any option or warrant to purchase any
shares of common stock, any securities convertible into any shares of common
stock, or any other equity security of the Bank; (ii) to make a tender or
exchange offer for any shares of such common stock or other equity security;
(iii) to purchase, lease, or otherwise acquire the assets of the Bank except in
the ordinary course of business; or (iv) to merge, consolidate, or otherwise
combine with the Bank.
 
WAIVER, AMENDMENT, AND TERMINATION
 
     Either Norwest or the Bank may, in writing, give any consent, take any
action, or waive any inaccuracies in the representations and warranties of the
other party or compliance by the other party with any of the covenants and
conditions in the Consolidation Agreement.
 
     At any time before the Time of Filing the parties may amend the
Consolidation Agreement by action of their respective Boards of Directors or
pursuant to authority delegated by their respective Boards of Directors;
provided, however, that no such amendment occurring after approval of the
Consolidation by the Bank shareholders may adversely affect the consideration to
be received by the Bank shareholders.
 
     The Consolidation Agreement may be terminated at any time prior to the Time
of Filing (i) by mutual written consent of the parties; (ii) by either party by
written notice to the other if the Consolidation shall not have been consummated
by December 31, 1994, unless such failure of consummation is due to the failure
of the party seeking termination to perform or observe in all material respects
the covenants and agreements to be performed or observed by it under the
Consolidation Agreement; or (iii) by either party by written notice to the other
if any court or governmental authority of competent jurisdiction shall have
issued a final order restraining, enjoining, or otherwise prohibiting the
consummation of the transactions contemplated by the Consolidation Agreement.
 
MANAGEMENT AND OPERATIONS AFTER THE CONSOLIDATION
 
     After the Consolidation, the Bank will become a wholly owned subsidiary of
Norwest and will continue to operate at its present locations. Products and
services offered by Norwest affiliates will be offered through the offices of
the Bank.
 
INTERESTS OF CERTAIN PERSONS IN THE CONSOLIDATION
 
     In considering the recommendation of the Bank's Board of Directors with
respect to the Consolidation, shareholders of the Bank should be aware that
certain officers and directors of the Bank have certain direct or indirect
interests separate from their interests as holders of the Bank Common Stock,
including those referred to below.
 
                                       19
<PAGE>   24
 
     After the Effective Time of the Consolidation, the officers and directors
of the Bank will continue to be officers and directors of the Bank until such
time as their successors are elected and will be entitled to participate in the
Norwest benefit plans.
 
     Mr. William R. Goertz, President of the Bank, and Mr. Don C. Kendrick,
Executive Vice President of the Bank, presently hold options to acquire 2,800
shares and 900 shares, respectively, of Bank Common Stock, which options will be
assumed by Norwest and become options to purchase shares of Norwest Common Stock
on the same basis as though such options had been exercised prior to the
Effective Time of the Consolidation.
 
CERTAIN DIFFERENCES IN RIGHTS OF SHAREHOLDERS
 
     The Bank is organized as a national banking association under the laws of
the United States, and Norwest is incorporated as a corporation in the State of
Delaware. Shareholders of the Bank, whose rights are governed by the Bank's
Articles of Association and By-Laws and by federal banking law, will, upon
consummation of the Consolidation, become stockholders of Norwest. Their rights
as Norwest stockholders will then be governed by Norwest's Certificate of
Incorporation and By-Laws and by the Delaware General Corporation Law. The
following is a summary of certain significant differences between the rights of
shareholders of the Bank and the rights of stockholders of Norwest.
 
     Capital Stock
 
     THE BANK. The Bank's Articles of Association authorize the issuance of
50,000 shares of common stock, par value $100.00 per share, in such series and
with such rights and preferences as the Board of Directors shall determine. All
shares of Bank Common Stock currently outstanding have equal rights and
preferences with respect to voting, dividends, and distributions upon
liquidation.
 
     NORWEST. Norwest's Certificate of Incorporation authorizes the issuance of
500,000,000 shares of Common Stock, par value $1 2/3 per share, and 5,000,000
shares of preferred stock, without par value ("Preferred Stock"). At June 30,
1994, 323,084,474 shares of Common Stock were issued, of which 315,457,227 were
outstanding and 7,627,247 were held as treasury shares, and 2,306,000 shares of
Preferred Stock were outstanding consisting of 1,127,125 shares of 10.24%
Cumulative Preferred Stock, 1,143,750 shares of Cumulative Convertible Preferred
Stock, Series B, and 35,125 shares of ESOP Cumulative Convertible Preferred
Stock. In addition, 1,000,000 shares of Preferred Stock are reserved for
issuance under the Rights Agreement dated as of November 22, 1988, between
Citibank, N.A. as Rights Agent, and Norwest (the "Rights Agreement"). Norwest
has also authorized for issuance from time to time and registered with the
Commission an additional 1,700,000 shares of Preferred Stock. Norwest has also
authorized for issuance from time to time and registered with the SEC pursuant
to a universal shelf registration statement, an indeterminate number of
securities (the "Shelf Securities") with an aggregate initial offering price not
to exceed $1,000,000,000. The Shelf Securities may be issued as Preferred Stock
or as securities convertible into shares of Preferred Stock or Common Stock.
Based on the current number of shares of Preferred Stock authorized for issuance
under Norwest's Certificate of Incorporation, the maximum number of shares of
Preferred Stock and Common Stock, respectively, that could be issued pursuant to
the effective shelf registration statements, when added to shares of Preferred
Stock and Common Stock already reserved for issuance, issued, or outstanding,
could not exceed respectively, 5,000,000 shares of Preferred Stock and
500,000,000 shares of Common Stock. All or any portion of the authorized but
unissued Preferred Stock or Shelf Securities issuable as Preferred Stock or
convertible into Preferred Stock or Common Stock, may be issued by the Board of
Directors of Norwest without further action by stockholders. Holders of
Preferred Stock have certain rights and preferences with respect to dividends
and upon liquidation that are superior to those of holders of Common Stock. The
relative rights and preferences of any Preferred Stock issued in the future may
be established by Norwest's Board of Directors without stockholder action.
Although management has no current plans for the issuance of any shares of
Preferred Stock, except as disclosed in this Prospectus, such shares, when and
if issued, could have dividend, liquidation, voting and other rights superior to
those of the Common Stock.
 
                                       20
<PAGE>   25
 
     Subject to any prior rights of any Preferred Stock then outstanding,
holders of Common Stock are entitled to receive such dividends as are declared
by Norwest's Board of Directors out of funds legally available for that purpose.
For information concerning legal limitations on the ability of Norwest's banking
subsidiaries to supply funds to Norwest, see "CERTAIN REGULATORY
CONSIDERATIONS." Subject to the rights, if any, of any Preferred Stock then
outstanding, all voting rights are vested in the holders of Common Stock, each
share being entitled to one vote. Subject to any prior rights of any Preferred
Stock, in the event of liquidation, dissolution, or winding up of Norwest,
holders of shares of Common Stock are entitled to receive pro rata any assets
distributable to stockholders in respect of shares held by them. Holders of
shares of Common Stock do not have any preemptive right to subscribe for any
additional securities which may be issued by Norwest. The outstanding shares of
Common Stock, including the Shares offered hereby, are fully paid and
nonassessable. The transfer agent and registrar for the Common Stock is Norwest
Bank Minnesota, N.A. Each share of Common Stock also includes, and each share
offered hereby will include, a right to purchase certain Preferred Stock. See
"Rights to Purchase Preferred Stock" below.
 
     The foregoing description of the material terms of the Common Stock does
not purport to be complete and is qualified in its entirety by reference to
Article Fourth of Norwest's Certificate of Incorporation.
 
     On November 22, 1988, the Board of Directors of Norwest declared a dividend
of one preferred share purchase right (collectively, the "Rights") for each
outstanding share of Norwest Common Stock. The dividend was paid on December 9,
1988, to stockholders of record on that date. Holders of shares of Norwest
Common Stock issued subsequent to that date, including those to be issued in
connection with the Consolidation, will receive the Rights with their shares.
 
     The Rights trade automatically with shares of Norwest Common Stock and
become exercisable only under certain circumstances. The Rights are designed to
protect the interests of Norwest and its stockholders against coercive takeover
tactics. The purpose of the Rights is to encourage potential acquirors to
negotiate with Norwest's Board of Directors prior to attempting a takeover and
to give the Board leverage in negotiating on behalf of all stockholders the
terms of any proposed takeover. The Rights may, but are not intended to, deter
takeover proposals.
 
     Until a Right is exercised, the holder of a Right, as such, will have no
rights as a stockholder of Norwest including, without limitation, the right to
vote or receive dividends. Upon becoming exercisable, each Right will entitle
the registered holder to purchase from Norwest one four-hundredth of a share of
Norwest Series A Junior Participating Preferred Stock (collectively, the "Junior
Preferred Shares"). The stated purchase price for each one one-hundredth of a
Junior Preferred Share is $175.00. The purchase price is subject to adjustment
upon the occurrence of certain events, including stock dividends on the Junior
Preferred Shares or issuance of warrants for, or securities convertible on
certain terms into, Junior Preferred Shares. The number of Rights outstanding
and the number of Junior Preferred Shares issuable upon exercise of the Rights
are subject to adjustment in the event of a stock split of, or a stock dividend
on, Norwest Common Stock.
 
     The Rights will become exercisable only if a person or group acquires or
announces an offer to acquire 25% or more of the outstanding shares of Norwest
Common Stock. This triggering percentage may be reduced to no less than 15% by
the Board of Directors prior to the time the Rights become exercisable. The
Rights have certain additional features that will be triggered upon the
occurrence of specified events:
 
          (1) If a person or group acquires at least the triggering percentage
     of Norwest Common Stock, the Rights permit holders of the Rights, other
     than such person or group, to acquire Norwest Common Stock at 50% of market
     value. However, this feature will not apply if a person or group which owns
     less than the triggering percentage acquires at least 85% of the
     outstanding shares of Norwest Common Stock pursuant to a cash tender offer
     for 100% of the outstanding Norwest Common Stock.
 
          (2) After a person or group acquires at least the triggering
     percentage and before the acquiror owns 50% of the outstanding shares of
     Norwest Common Stock, the Board of Directors may exchange each Right, other
     than Rights owned by such acquiror, for one share of Norwest Common Stock
     or one four-hundredth of a Junior Preferred Share.
 
                                       21
<PAGE>   26
 
          (3) In the event of certain business combinations involving Norwest or
     the sale of 50% or more of the assets or earning power of Norwest, the
     Rights permit holders of the Rights to purchase the stock of the acquiror
     at 50% of market value.
 
     The Junior Preferred Shares will not be redeemable. Each Junior Preferred
Share will be entitled to a minimum preferential quarterly dividend payment of
$1.00 per share but will be entitled to an aggregate dividend of 400 times the
dividend declared per share of Norwest Common Stock. In the event of
liquidation, the holders of the Junior Preferred Shares will be entitled to a
minimum preferential liquidation payment of $400.00 per share but will be
entitled to an aggregate payment of 400 times the payment made per share of
Norwest Common Stock. Each Junior Preferred Share will have 400 votes, voting
together with the Norwest Common Stock. Finally, in the event of any merger,
consolidation, or other transaction in which Norwest Common Stock is exchanged,
each Junior Preferred Share will be entitled to receive 400 times the amount
received per share of Norwest Common Stock. These rights are protected by
customary antidilution provisions.
 
     At any time prior to the acquisition by a person or group of the triggering
percentage or more of the outstanding shares of Norwest Common Stock, the Board
of Directors may redeem the Rights in whole, but not in part, at a price of
$.0025 per Right (the "Redemption Price"). The redemption of the Rights may be
made effective at such time, on such basis, and with such conditions as the
Board of Directors in its sole discretion may establish. Immediately upon any
redemption of the Rights, the right to exercise the Rights will terminate and
the only remaining right of the holders of Rights will be to receive the
Redemption Price.
 
     The Rights will expire on November 23, 1998, unless extended or earlier
redeemed by Norwest. Generally, the terms of the Rights may be amended by the
Board of Directors without the consent of the holders of the Rights.
 
     Required Vote for Authorization of Certain Actions
 
     THE BANK. Under federal law the affirmative vote of the holders of at least
two-thirds of the outstanding shares of Bank Common Stock is required to approve
a merger or consolidation.
 
     NORWEST. Under Delaware law the vote of a simple majority of the
outstanding shares of Norwest Common Stock entitled to vote thereon is required
to approve a merger or consolidation, or the sale, lease, or exchange of
substantially all of Norwest's corporate assets. With respect to a merger, no
vote of the stockholders of Norwest is required if Norwest is the surviving
corporation and (1) the related agreement of merger does not amend Norwest's
Certificate of Incorporation, (2) each share of stock of Norwest outstanding
immediately before the merger is an identical outstanding or treasury share of
Norwest after the merger, and (3) the number of shares of Norwest stock to be
issued in the merger (or to be issuable upon conversion of any convertible
instruments to be issued in the merger) does not exceed 20% of the shares of
Norwest Common Stock outstanding immediately before the merger.
 
     In addition to being subject to the laws of Delaware, Norwest, as a bank
holding company, is subject to various provisions of federal law with respect to
mergers, consolidations and certain other corporate transactions.
 
     Dissenters' Rights
 
     THE BANK. Under federal law any shareholder of the Bank is entitled to
receive payment of the value of such shareholder's shares of the Bank capital
stock if such shareholder dissents from any merger or consolidation for which a
vote of the Bank's shareholders is required. See the more detailed discussion
below under "Rights of Dissenting Bank Shareholders."
 
     NORWEST. Under Delaware law a stockholder is generally entitled to receive
payment of the appraised value of such stockholder's shares if the stockholder
dissents from a merger or consolidation. However, appraisal rights are not
available to holders of (a) shares listed on a national securities exchange or
held of record by more than 2,000 persons or (b) shares of the corporation
surviving a merger, if the merger did not require the approval of the
stockholders of such corporation, unless in either case, the holders of such
stock are
 
                                       22
<PAGE>   27
 
required by the terms of the consolidation to accept anything other than (i)
shares of stock of the surviving corporation, (ii) shares of stock of another
corporation which are also listed on a national securities exchange or held by
more than 2,000 holders, or (iii) cash in lieu of fractional shares of such
stock. Appraisal rights are not available for a sale of assets or an amendment
to the Certificate of Incorporation. Because shares of Norwest Common Stock are
listed on both the NYSE and the CHX, and Norwest has more than 2,000
stockholders of record, its stockholders are not, subject to the aforementioned
exceptions, entitled to any rights of appraisal in connection with mergers or
consolidations involving Norwest.
 
     Special Meetings
 
     THE BANK. Under federal law and the Bank's By-Laws, a special meeting of
the Bank's shareholders may be called by the Bank's Board of Directors, or by
three or more shareholders owning, in the aggregate, not less than ten percent
of all of the outstanding shares of the Bank.
 
     NORWEST. Under Delaware law and the By-Laws of Norwest, a special meeting
of stockholders may be called only by the Chairman of the Board, a Vice
Chairman, the President, or a majority of the Board of Directors.
 
     Antitakeover Statutes
 
     THE BANK. National banking associations are not covered by any specific
antitakeover statute. However, the acquisition of more than 5% of the capital
stock of a national bank requires the approval of federal regulatory agencies.
 
     NORWEST. The Delaware antitakeover statute governs "business combinations"
between a publicly held Delaware corporation having certain numbers of
stockholders or listed on certain exchanges and an "interested stockholder."
This statute is designed primarily to regulate the second step of a two-tiered
takeover attempt. Delaware law broadly defines a "business combination" as
including a merger, sale of assets, issuance of voting stock, and various other
types of transactions with an interested stockholder and other related parties.
An "interested stockholder" is defined as any person who beneficially owns,
directly or indirectly, 15% or more of the outstanding voting stock of a
corporation. Delaware law prohibits a corporation from engaging in a business
combination with an interested stockholder for a period of three years following
the date on which the stockholder became an interested stockholder unless (a)
the board of directors approved the business combination before the stockholder
became an interested stockholder, (b) upon consummation of the transaction which
resulted in the stockholder becoming an interested stockholder, such stockholder
owned at least 85% of the voting stock outstanding when the transaction began,
excluding in computing such percentage shares held by certain types of
stockholders, or (c) the board of directors approved the business combination
after the stockholder became an interested stockholder and the business
combination was approved by at least two-thirds of the outstanding voting stock
not owned by such stockholder.
 
RIGHTS OF DISSENTING BANK SHAREHOLDERS
 
     Title 12, Section 215, of the United States Code provides that any
shareholder of either of the parties to a consolidation involving a national
bank who objects to the proposed consolidation has the right to receive payment
in cash of the value of such shareholder's shares as of the effective date of
the consolidation, if and when the consolidation is consummated, subject to
certain conditions. These conditions, in the case of a shareholder of the Bank,
are that: (i) the shareholder must have voted against approval of the
Consolidation at the Special Meeting or given notice in writing at, or prior to,
the Special Meeting to the presiding officer that such shareholder dissents from
the proposed Consolidation; (ii) the shareholder must, within 30 days after the
effective date of the Consolidation, make a written request for payment to the
surviving bank; and (iii) the written request must be accompanied by surrender
of the shareholder's stock certificate(s). Any shareholder of the Bank who votes
against the Consolidation at the Special Meeting, or who gives notice in writing
at, or prior to, the Special Meeting to the presiding officer that such
shareholder dissents, will be notified in writing of the effective date of the
Consolidation. Failure to comply with each of the foregoing conditions will
result in the loss of the appraisal rights described herein.
 
                                       23
<PAGE>   28
 
     The value of the shares of any dissenting shareholder shall be determined
by an appraisal made by a committee of three persons, one to be selected by the
majority vote of the dissenting shareholders, one by the Board of Directors of
the surviving bank, and the third by the two so chosen. The valuation agreed
upon by any two of the three appraisers shall govern. If the value so fixed is
not satisfactory to any dissenting shareholder, that shareholder may, within
five days after being notified of the appraised value of such shareholder's
shares, appeal to the Comptroller of the Currency, who shall cause a reappraisal
to be made which shall be final and binding as to the value of such shares. If a
shareholder dissents and, within 90 days from the date of consummation of the
Consolidation, one or more of the appraisers is not selected as above provided
for any reason, or the appraisers fail to determine the value of such shares,
the Comptroller shall, upon written request of any interested party, cause an
appraisal to be made which shall be final and binding on all parties. The
expenses of the Comptroller in making the reappraisal or the appraisal, as the
case may be, shall be paid by the surviving bank. The value of the shares
ascertained shall be promptly paid to the dissenting shareholder by the
surviving bank.
 
     The foregoing summary does not purport to be a complete statement of the
provisions of Section 215 and is qualified in its entirety by reference to the
relevant provisions of Section 215, the text of which is attached hereto as
Exhibit B. Any shareholder of the Bank who desires to exercise dissenters'
appraisal rights should carefully review and comply with the relevant provisions
of Section 215. DISSENTERS' RIGHTS WILL BE LOST IF THE PROCEDURAL REQUIREMENTS
OF SECTION 215 ARE NOT FULLY AND PRECISELY SATISFIED.
 
     Attached hereto as Appendix C is a copy of Banking Circular 259 regarding
the valuation methods used by the Comptroller to estimate the value of a bank's
shares when the Comptroller is involved in the appraisal of shares held by
dissenting shareholders. The results of appraisals performed by the Comptroller
between January 1, 1985, and September 30, 1991, are also summarized in Appendix
C. EACH SHAREHOLDER OF THE BANK SHOULD FULLY CONSIDER APPENDIX C BEFORE DECIDING
WHETHER TO EXERCISE DISSENTERS' RIGHTS.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion summarizes certain U.S. Federal income tax
consequences of the Consolidation to holders of Bank Common Stock under the
Internal Revenue Code of 1986, as amended (the "Code").
 
     This summary should not be regarded as a substitute for an individual
analysis of the tax consequences of the Consolidation to a Bank shareholder.
Each Bank shareholder should consult a tax advisor regarding the particular tax
consequences of the Consolidation to such shareholder's own situation.
 
     None of Norwest, Norwest Interim Bank, and the Bank has requested a ruling
from the Internal Revenue Service (the "Service") in connection with the
Consolidation. The Bank will receive from its counsel, Vinson & Elkins, an
opinion to the effect that the Consolidation will be treated for U.S. Federal
income tax purposes as a reorganization within the meaning of Section 368(a) of
the Code, that Norwest, Norwest Interim Bank, and the Bank will each be a party
to the reorganization within the meaning of Section 368(b) of the Code, and that
shareholders of the Bank (other than holders of the Bank Common Stock who
exercise dissenters' rights) will not recognize any gain or loss as a result of
the Consolidation, except to the extent they receive cash in lieu of a
fractional share of the Bank Common Stock. Such opinion will be subject to
certain assumptions and based on certain representations of Norwest, Norwest
Interim Bank, and the Bank and affiliates of the Bank. The Bank shareholders
should be aware that such opinion will neither be binding upon the Service nor
will the Service be precluded from adopting a contrary position.
 
     Assuming the Consolidation qualifies as a reorganization under Section
368(a) of the Code, the following U.S. Federal income tax consequences will
occur:
 
          (a) No gain or loss will be recognized by Norwest, Norwest Interim
     Bank, and the Bank in connection with the Consolidation;
 
          (b) No gain or loss will be recognized by a holder of Bank Common
     Stock who exchanges all of his shares of Bank Common Stock solely for
     shares of Norwest Common Stock in the Consolidation;
 
                                       24
<PAGE>   29
 
          (c) The aggregate basis of the shares of Norwest Common Stock to be
     received by a Bank shareholder in the Consolidation (including any
     fractional share not actually received) will be the same as the aggregate
     basis of the shares of Bank Common Stock surrendered in exchange therefor;
 
          (d) The holding period of the shares of Norwest Common Stock to be
     received by a Bank shareholder in the Consolidation will include the
     holding period of the shares of Bank Common Stock surrendered in exchange
     therefor, provided that such shares of Bank Common Stock are held as
     capital assets at the Effective Time of the Consolidation;
 
          (e) Cash payments in lieu of a fractional share will be treated as if
     a fractional share of Norwest Common Stock has been received in the
     Consolidation and then redeemed by Norwest. Such a redemption should
     qualify as a distribution in full payment in exchange for the fractional
     share rather than as a distribution of a dividend. Accordingly, a Bank
     shareholder receiving cash in lieu of a fractional share will recognize
     gain or loss upon such payment equal to the difference, if any, between
     such shareholder's basis in the fractional share (as described in paragraph
     (c) above) and the amount of cash received. Such gain or loss will be a
     capital gain or loss if the Bank Common Stock is held as a capital asset at
     the Effective Time of the Consolidation; and
 
          (f) With respect to a Bank shareholder who perfects his dissenters'
     rights under the National Bank Act with regard to the Consolidation and
     receives cash for the value of his Bank Common Stock, the Service should
     treat such cash as having been received as a distribution from the Bank in
     redemption of such Bank Common Stock. Such redemption would be treated as a
     distribution in full payment in exchange for such Bank Common Stock, and
     thus the dissenting shareholder would recognize gain or loss measured by
     the difference between the cash received and the basis for such Bank Common
     Stock, if the redemption does not have the effect of the distribution of a
     dividend under Section 302 of the Code (after applying the constructive
     ownership rules of Section 318 of the Code).
 
RESALE OF NORWEST COMMON STOCK
 
     The shares of Norwest Common Stock issuable to shareholders of the Bank
upon consummation of the Consolidation have been registered under the Securities
Act of 1933 (the "Securities Act"). Such shares may be traded freely and without
restriction by those shareholders not deemed to be "affiliates" of the Bank or
Norwest as that term is defined in the rules under the Securities Act. Norwest
Common Stock received by those shareholders of the Bank who are deemed to be
"affiliates" of the Bank may be resold without registration as provided for by
Rule 145, or as otherwise permitted under the Securities Act. In the
Consolidation Agreement, the Bank has agreed to use its best efforts to cause
each Bank shareholder who is an executive officer or director of the Bank or who
may otherwise reasonably be deemed to be an affiliate of the Bank to enter into
an agreement with Norwest providing that such affiliate will not sell, transfer,
or otherwise dispose of the shares of Norwest Common Stock to be received by
such person in the Consolidation except in compliance with the applicable
provisions of the Securities Act and the rules and regulations promulgated
thereunder. This Proxy Statement-Prospectus does not cover any resales of
Norwest Common Stock received by affiliates of the Bank.
 
     Pursuant to the Agreement, Norwest and the Bank have agreed to use their
best efforts to cause their affiliates to execute written agreements not to take
any action that would cause the Consolidation not to be treated as a pooling of
interests for accounting purposes. Under generally accepted accounting
principles, the sale of Norwest Common Stock or Bank Common Stock by an
affiliate of either Norwest or the Bank within 30 days prior to the Effective
Time of the Consolidation or thereafter prior to the publication of financial
statements that include at least 30 days of combined operations of Norwest and
the Bank after the Effective Time of the Consolidation could preclude pooling of
interests accounting treatment of the Consolidation.
 
     The Consolidation Agreement provides for the filing by Norwest of listing
applications with the NYSE and the CHX covering the shares of Norwest Common
Stock issuable upon consummation of the Consolidation. It is a condition to the
consummation of the Consolidation that such shares of Norwest Common Stock shall
have been authorized for listing on the NYSE and the CHX effective upon official
notice of issuance.

DIVIDEND REINVESTMENT AND OPTIONAL CASH PAYMENT PLAN
 
     For those stockholders who elect to participate in Norwest's Dividend
Reinvestment and Optional Cash Payment Plan, dividends on Norwest Common Stock
will be reinvested in shares of Norwest Common Stock at market price (as
defined). The plan also permits participants to invest through voluntary cash
payments, within certain dollar limitations, in additional shares of Norwest
Common Stock at the market price (as defined) of such stock at the time of
purchase. It is anticipated that after the Effective Time of the Consolidation,
Norwest will continue to offer its Dividend Reinvestment and Optional Cash
Payment Plan and that shareholders of the Bank who receive Norwest Common Stock
in the Consolidation will have the right to participate therein.
 
ACCOUNTING TREATMENT
 
     Notwithstanding any provision of the Consolidation Agreement to the
contrary, management of Norwest has decided that the Consolidation will be
accounted for as a purchase in accordance with generally accepted accounting
principles.
 
EXPENSES
 
     Norwest and the Bank will each pay their own expenses in connection with
the Consolidation and the transactions contemplated thereby, including fees and
expenses of their respective accountants and counsel.

                           INFORMATION ABOUT THE BANK
 
BUSINESS AND PROPERTY OF THE BANK
 
     GENERAL. The Bank is a national bank headquartered in Kerrville, Texas,
that provides retail and commercial banking services to its customers through
three community banking offices, two offices being located in Kerrville and the
third located in the adjacent town of Ingram. The Bank's deposits are insured by
the Bank Insurance Fund of the Federal Deposit Insurance Corporation (the
"FDIC"). At June 30, 1994, the Bank had total assets of $204.2 million, deposits
of $187.0 million, and stockholders' equity of $16.7 million. The Bank was
chartered as a state bank in 1907 and converted to a national bank in 1959.
 
     The Bank provides a wide range of banking services for its retail and
commercial customers, including real estate loans, revolving credit
arrangements, inventory and accounts receivable financing, equipment financing,
home improvement and other personal loans, NOW checking, savings and time
accounts, and trust services. The Bank provides 24-hour access to routine
banking services through its automated teller machines.
 
     The Bank's business strategy has been to develop long-term customer
relationships, maintain high quality service and respond quickly to the needs of
its customers. The Bank supports active participation of its personnel in local
charitable, civic, school, and church activities. The Bank has installed data
processing and telecommunications systems and facilities to adequately service
its customers and its growth in the area. The Bank's customers are located
primarily in Kerr County, Texas.
 
     COMPETITION. The Bank is subject to competition in all aspects of its
business from other banks and financial institutions in its immediate market
area as well as those located in San Antonio. The Bank has been able to compete
effectively by emphasizing customer service, establishing long-term customer
relationships, and building customer loyalty through providing the products and
personal services designed to meet the specific needs of its customers.
 
     EMPLOYEES. At June 30, 1994, the Bank had 98 full-time employees (which
includes 31 officers) and 25 part-time employees.
 
     BANKING LOCATIONS. The main facility of the Bank is located at 301 Junction
Highway in Kerrville, Texas. The main facility is a three-story building and
consists of a walk-in lobby, a commercial lobby, executive offices,
administrative offices and eight drive-in lanes. The Bank's second facility is
located at 222 Sidney Baker South in a six-story condominium building. The Bank
owns the first and second floors of this building, and its facilities include a
walk-in lobby, offices and five drive-in teller lanes. The Bank's third facility
is in a two-story building located at 110 Highway 27 East in Ingram, Texas,
which was purchased by the Bank from the FDIC in September 1990. The Ingram
facility also consists of a bank lobby, offices, and four drive-in teller lanes.
 
ENVIRONMENTAL PROTECTION CONSIDERATIONS
 
     It is a condition to Norwest's obligation to consummate the Consolidation
that there be no reasonable basis for an environmental proceeding, claim, or
action that could result in liability which could reasonably be expected to have
a material adverse effect on the Bank. The Bank is aware of no such potential
proceeding, claim, or action.
 
MARKET PRICES AND DIVIDENDS
 
     Other than director qualifying shares, the outstanding shares of the Bank
are owned by one individual. Therefore, there is not an established trading
market for Bank Common Stock. As of the record date for the Special Meeting,
there were nine holders of record of shares of Bank Common Stock and 25,000
shares outstanding.
 
     The Bank paid dividends on its Common Stock of $20.00 and $6.00 per share
in fiscal years 1993 and 1992, respectively, and no dividends were paid in
fiscal year 1991 or to date in 1994.

GENERAL
 
     The following is management's discussion and analysis of the significant
factors affecting the Bank's results of operations and financial condition. This
should be read in conjunction with the audited financial statements and
accompanying footnotes and other selected financial data presented elsewhere
herein.
 
FINANCIAL CONDITION
 
     Total assets decreased by $10,186,000 during the first six months of 1994
to $204,170,000 at June 30, 1994 following an increase of $43,426,000 during
1993 to $214,356,000 at December 31, 1993. The 1994
 
                                       28
<PAGE>   33
 
decrease was primarily due to decreases in investments and net loans. The 1993
increase was due to the purchase of the Bank of Kerrville (BOK) in July 1993.
BOK was a state-chartered community bank located in Kerrville, Texas, with
approximately $52 million in total assets.
 
     Loans decreased $2,416,000 during the first six months of 1994 to
$91,538,000 at June 30, 1994. Investments decreased $4,315,000 during the first
six months of 1994 to $87,325,000 at June 30, 1994. These decreases during the
first six months of 1994 were offset by reductions in deposits of $6,620,000,
primarily due to low interest rates and the outflow of interest-bearing deposits
to alternative deposit products (annuities and mutual funds), as well as the
loss of some deposits after the acquisition of BOK for customers exceeding the
FDIC insurance coverage amounts.
 
COMPARISON OF SIX MONTHS ENDED JUNE 30, 1994, AND 1993
 
     General
 
     The Bank's net income decreased 1.72 percent to $1,604,000 for the six
months ended June 30, 1994 from $1,632,000 for the six months ended June 30,
1993. During this period, the Bank's net interest income increased to $4,432,000
from $3,812,000. Noninterest income, excluding gains on sales of securities and
other real estate owned, increased $184,000 to $1,127,000 in 1994 from $943,000
in 1993, which includes an 11.90 percent increase in trust fees to $349,000 in
1994 from $312,000 in 1993. Net gains on sales of securities decreased $203,000
to $247,000 in 1994 from $450,000 in 1993. Operating expenses increased $651,000
to $3,650,000 in 1994 from $2,999,000 in 1993. The increase was primarily due to
increased costs (occupancy, salaries, data processing, etc.) associated with the
BOK acquisition. Return on average assets and return on average equity on an
annualized basis were 1.56 percent and 19.76 percent, respectively, for the six
month period ended June 30, 1994, compared with 1.97 percent and 24.66 percent,
respectively, for the same period in 1993. Total assets decreased 4.75 percent
to $204,170,000 at June 30, 1994, from $214,356,000 at December 31, 1993. During
the same period, gross loans decreased $2,319,000 and investment securities
decreased $4,315,000. The decrease in loans is primarily due to accelerated
prepayments while the decrease in securities is primarily due to the loss of
interest bearing deposits to higher yielding alternative deposit products such
as mutual funds and annuities.
 
     Net Interest Margin
 
     The Bank's taxable-equivalent net interest margin decreased on an
annualized basis to 4.77 percent for the six months ended June 30, 1994, from
5.09 percent for the six months ended June 30, 1993. Taxable-equivalent interest
income increased 15.45 percent to $6,485,000 from $5,617,000, and interest
expense increased 11.90 percent to $1,983,000 from $1,772,000. The increase in
interest income and expense resulted primarily from increased volumes (BOK).
 
     Noninterest Income and Expense
 
     The $184,000 increase in noninterest income, excluding gains on sales of
securities and other real estate, during the first six months of 1994 mainly
resulted from service charges on an increased deposit base (BOK) and trust fees.
Noninterest expense increased $651,000 during the first six months of 1994
compared to the same period in 1993. This increase resulted primarily from
increases in salaries and benefits, occupancy, and data processing costs
resulting from the BOK acquisition.

</TABLE>
 
     Total operating expenses increased to $3,650,000 for the first six months
of 1994 compared to $2,999,000 for the first six months of 1993; however, there
are no associated costs of BOK included in 1993.
 
COMPARISON OF YEARS ENDED DECEMBER 31, 1993, 1992, AND 1991
 
     General
 
     The Bank's net income increased to $3,892,000 for the year ended December
31, 1993, compared to $2,432,000 for the year ended December 31, 1992 and
$1,715,000 for the year ended December 31, 1991. Return on average assets and
return on average equity were 2.10 percent and 28.10 percent, respectively, for
1993 as compared to 1.47 percent and 21.55 percent, respectively, for 1992.
Total assets increased $43,426,000 to $214,356,000 at December 31, 1993 from
$170,930,000 at December 31, 1992. Gross loans increased $21,032,000 and
investment securities increased $23,043,000 in 1993. Deposits increased
$35,479,000 in 1993 as the result of an increase of $10,387,000 in
noninterest-bearing deposits and an increase of $25,092,000 in interest-bearing
deposits. These increases in loans, securities, and deposits primarily resulted
from the acquisition of BOK.
 
     Net Interest Income
 
     The Bank's taxable-equivalent net interest income to average earnings
assets increased to 4.94 percent in 1993 from 4.87 percent in 1992 and 4.11
percent in 1991. Taxable-equivalent interest income was $12,220,000 for the year
ended December 31, 1993, compared to $11,963,000 for December 31, 1992, and
$14,452,000 for December 31, 1991. Interest expense decreased 17.45 percent to
$3,893,000 for the year ended December 31, 1993, compared to $4,716,000 for
December 31, 1992 and $7,978,000 for December 31, 1991. Taxable-equivalent yield
on interest-bearing assets was 7.20 percent in fiscal 1993 compared to 8.02
percent and 9.17 percent for fiscal 1992 and 1991, respectively. The average
cost of interest-bearing liabilities was 2.68 percent in fiscal 1993 compared to
3.51 percent and 5.57 percent for fiscal 1992 and 1991, respectively.
 
     Allowance for Loan Losses
 
     The allowance for loan losses is established by a charge to income as a
provision for loan losses. Actual loan losses or recoveries are charged or
credited directly to this allowance. The provision for loan losses is based on
management's estimate of the amounts required to maintain an allowance adequate
to reflect losses inherent in the loan portfolio at the balance sheet date;
however, ultimate losses may vary from the current estimates. In estimating
losses, consideration is given to the financial condition of the borrower,
guarantor, current and anticipated economic conditions and collateral values.
These estimates are reviewed periodically, and adjustments to either increase or
decrease the allowance are reported in earnings in the period in which they
become known.
 
     Management believes that the Bank's allowance for loan losses is adequate
to cover known or anticipated losses. There can be no assurance, however, that
management will not decide to increase the allowance for loan losses or that
regulators, when reviewing the Bank's loan portfolios in the future, will not
request the Bank
 
                                       30
<PAGE>   35
 
to increase such allowance, either of which could adversely affect the Bank's
earnings. Further, there can be no assurance that the Bank's actual loan losses
will not exceed it's allowance for loan losses.
 
     The Bank's provision (reversion) for loan losses was ($1,500,000),
$135,000, and $1,166,000 for the years ended December 31, 1993, 1992 and 1991,
respectively. The reversion in 1993 was made after extensive analysis of the
Bank's loan loss reserve and was primarily attributable to decreases in actual
losses, recoveries on previously charged off loans and the overall economic
recovery in Texas.
 
     Noninterest Income and Expense
 
     Noninterest income, excluding gains on sales of securities and other real
estate increased $280,000 to $2,142,000 for the year ended December 31, 1993,
compared to $1,862,000 and $1,526,000 for the years ended 1992 and 1991,
respectively. Gains on sales of securities were $460,000, $14,000 and $499,000
for the years ended December 31, 1993, 1992 and 1991, respectively.
 
     Gains on the sales of other real estate owned were $337,000 and $29,000 for
the years ended December 31, 1993 and 1992, respectively.
 
     Noninterest expense increased $1,287,000 to $7,008,000 for the year ended
December 31, 1993, compared to $5,721,000 and $5,592,000 for the years ended
1992 and 1991, respectively. The following table presents a summary of operating
expenses and percentage changes (dollars in thousands):

     The increase in 1993 is largely attributable to the acquisition of the BOK
in July 1993.
 
CAPITAL RESOURCES
 
     At December 31, 1993, shareholders' equity was $15.6 million and
represented a $3.4 million or 27.87 percent increase from the December 31, 1992
balance of $12.2 million. The increase was due to the retention of earnings less
dividends paid. At June 30, 1994, shareholders' equity was $16.7 million and
represented a $1.1 million or 7.05 percent increase from December 31, 1993. The
increase was due to further retention of earnings.
 
     Bank regulatory agencies measure capital adequacy through standardized
risk-based capital guidelines which compare different levels of capital (as
defined by such guidelines) to risk-weighted assets and off-balance-sheet
obligations. Under the rules effective December 31, 1993, all financial
institutions are required to maintain a level of core capital (known as Tier 1
capital) which must be at least 4.00 percent of risk-weighted assets, and a
minimum level of total capital of at least 8.00 percent of risk-weighted assets.
Tier 1 capital consists principally of stockholders' equity less goodwill. Total
capital is comprised of Tier 1 capital, certain debt instruments and a portion
of the allowance for loan losses. The Bank's actual risk-based capital,

     As a supplement to the risk-based capital guidelines, banks must also
maintain a minimum ratio of Tier 1 capital to total assets, known as the Tier 1
leverage ratio. The principal objective of this measure is to place a constraint
on the maximum degree to which a banking organization can leverage its equity
capital base. This regulation has established a minimum level of Tier 1 capital
to total assets of 3.00 percent. At June 30, 1994, the Bank's leverage ratio was
7.48 percent, compared to 8.00 percent at December 31, 1993. This decrease from
December 31, 1993 to June 30, 1994, is primarily attributable to the reduction
in capital of $531,663 resultant from unrealized holding losses in the Bank's
available-for-sale investment portfolio. The decrease in the leverage ratio from
December 1992 to December 1993 is attributable to the BOK acquisition.
 
FUNDING SOURCES AND LIQUIDITY MANAGEMENT
 
     The Bank is restricted in paying dividends due to the general regulatory
capital requirements that apply to all banks. The approval of the OCC is
required for any dividend by a national bank if the total of all dividends
declared by the bank in any calendar year would exceed the total of its net
profits, as defined by regulatory agencies, for that year combined with its
retained net profits for the preceding two years less any required transfers to
surplus or a fund for the retirement of any preferred stock. In addition, a
national bank may not pay a dividend in an amount greater than its net profits
then on hand after deducting its losses and bad debts.
 
     The assets of the Bank are primarily funded through the use of borrowings
in the form of deposits and short-term borrowings. The maintenance of an
adequate level of liquidity is necessary to ensure that sufficient funds are
available to meet customers' loan demand and deposit withdrawals. The sources of
asset liquidity consist of federal funds, maturing loans and investment
securities. The Bank's basic strategy is to minimize interest rate risk through
matching the repricing periods of earning assets and interest-bearing
liabilities.
 
ACCOUNTING PRINCIPLES
 
     In December 1991, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 107, "Disclosures About
Fair Value of Financial Instruments." SFAS No. 107 requires all entities to
disclose the fair value of financial instruments, both assets and liabilities
recognized and not recognized in the balance sheet, for which it is practicable
to estimate fair value. The standard defines a financial instrument as cash,
evidence of an ownership in any entity, or a contract that conveys or imposes on
an entity the contractual right or obligation to either receive or deliver cash
or another financial instrument. Fair value is defined as the amount at which a
financial instrument could be exchanged in a current transaction between willing
parties, other than in a forced sale or liquidation, and is best evidenced by a
quoted market price if one exists.
 
     In May 1993, FASB issued SFAS No. 115, "Accounting for Certain Investments
in Debt and Equity Securities." SFAS No. 115 is effective for financial
statements issued for fiscal years beginning after December 15, 1993. The new
standard will require the classification of securities into three categories:
held-to-maturity, available-for-sale, or trading. Investments classified as
held-to-maturity are measured at amortized cost only if the reporting enterprise
has the positive intent and ability to hold those securities to maturity.
Securities that are bought and held principally for the purpose of selling them
in the near term shall be classified as trading securities. Unrealized holding
gains and losses shall be included in earnings. Investments
 
                                       32
<PAGE>   37
 
not classified as trading securities or held-to-maturity securities shall be
classified as available-for-sale. Securities that would be sold in response to
changes in market interest rates and securities' prepayment risk, needs for
liquidity or changes in the availability and yield on alternative investments
are classified as available-for-sale. Unrealized holding gains and losses shall
be excluded from earnings and reported as a net amount in a separate component
of stockholders' equity (net of deferred taxes) until realized. SFAS No. 115 was
adopted as of the beginning of the Bank's fiscal year, January 1, 1994, and, in
accordance with SFAS 115, was not applied retroactively.
 
     In May 1993, the FASB issued SFAS No. 114, "Accounting by Creditors for
Impairment of a Loan." SFAS No. 114 is effective for financial statements issued
for fiscal years beginning after December 15, 1994, although earlier adoption is
permitted. The new standard addresses the accounting by creditors for impairment
of certain loans, as well as the accounting for troubled debt restructurings. A
loan is impaired when, based on current information and events, it is probable
that a creditor will be unable to collect all amounts due according to the
contractual terms of the loan agreement. The standard requires that impaired
loans be measured based on the present value of expected future cash flows for
each loan discounted at the loan's effective interest rate or, as a practical
expedient, at the loan's observable market price or the fair value of the
collateral if the loan is collateral dependent. The Bank will adopt this
standard in 1995. Based on the loan portfolio as of June 30, 1994 (unaudited),
management believes the implementation of this standard will not have a material
effect on the Bank's financial position or results of operations.

     This table shows the components of the change in net interest income by
volume and rate on a taxable-equivalent basis. The effect of changes in rates on
volume changes is allocated based on the percentage relationship of changes in
volume and changes in rate. This table does not take into account the level of
noninterest-bearing funding nor does it fully reflect changes in the mix of
assets and liabilities.

                       CERTAIN REGULATORY CONSIDERATIONS
 
GENERAL
 
     As a bank holding company, Norwest is subject to supervision and
examination by the Federal Reserve Board. Norwest's banking subsidiaries are
subject to supervision and examination by applicable federal and state banking
agencies. The deposits of Norwest's banking subsidiaries are insured by the Bank
Insurance Fund of the Federal Deposit Insurance Corporation ("FDIC"), and
therefore such banking subsidiaries are subject to regulation by the FDIC. In
addition to the impact of regulation, commercial banks are affected
significantly by the actions of the Federal Reserve Board as it attempts to
control the money supply and credit availability in order to influence the
economy.
 
DIVIDEND RESTRICTIONS
 
     Various federal and state statutes and regulations limit the amount of
dividends the subsidiary banks can pay to Norwest without regulatory approval.
The approval of the OCC is required for any dividend by a national bank if the
total of all dividends declared by the bank in any calendar year would exceed
the total of its net profits, as defined by regulation, for that year combined
with its retained net profits for the preceding two years less any required
transfers to surplus or a fund for the retirement of any preferred stock. In
addition, a national bank may not pay a dividend in an amount greater than its
net profits then on hand after deducting its losses and bad debts. For this
purpose, bad debts are defined to include, generally, loans which have matured
and are in arrears with respect to interest by six months or more, other than
such loans which are well secured and in the process of collection. Under these
provisions Norwest's national bank subsidiaries could have declared, as of June
30, 1994, aggregate dividends of at least $384.2 million without obtaining prior
regulatory approval and without reducing the capital of the respective banks
below minimum levels. Norwest also has several state bank subsidiaries that are
subject to state regulations limiting dividends; however, the amount of
dividends payable by Norwest's state bank subsidiaries, with or without state
regulatory approval, would represent an immaterial contribution to Norwest's
revenues.
 
     If, in the opinion of the applicable regulatory authority, a bank under its
jurisdiction is engaged in or is about to engage in an unsafe or unsound
practice (which, depending on the financial condition of the bank, could include
the payment of dividends), such authority may require, after notice and hearing,
that such bank cease and desist from such practice. The Federal Reserve Board,
the OCC, and the FDIC have issued policy statements which provide the
FDIC-insured banks and bank holding companies should generally pay dividends
only out of current operating earnings.
 
HOLDING COMPANY STRUCTURE
 
     Norwest is a legal entity separate and distinct from its banking and
nonbanking subsidiaries. Accordingly, the right of Norwest, and thus the rights
of Norwest's creditors, to participate in any distribution of the assets or
earnings of any subsidiary is necessarily subject to the prior claims of
creditors of such subsidiary, except to the extent that claims of Norwest in its
capacity as a creditor may be recognized. The principal sources of Norwest's
revenues are dividends and fees from its subsidiaries.
 
     Norwest's banking subsidiaries are subject to restrictions under federal
law which limit the transfer of funds by the subsidiary banks to Norwest and its
nonbanking subsidiaries, whether in the form of loans, extensions of credit,
investments, or asset purchases. Such transfers by any subsidiary bank to
Norwest or any nonbanking subsidiary are limited in amount to 10% of the bank's
capital and surplus and, with respect to Norwest and all such nonbanking
subsidiaries, to an aggregate of 20% of such bank's capital and surplus.
Furthermore, such loans and extensions of credit are required to be secured in
specified amounts.
 
     The Federal Reserve Board has a policy to the effect that a bank holding
company is expected to act as a source of financial and managerial strength to
each of its subsidiary banks and to commit resources to support each such
subsidiary bank. This support may be required at times when Norwest may not have
the resources to provide it. Any capital loans by Norwest to any of the
subsidiary banks are subordinate in right of payment to deposits and to certain
other indebtedness of such subsidiary bank. In addition, the Crime Control Act
of
 
                                       44
<PAGE>   49
 
1990 provides that in the event of a bank holding company's bankruptcy, any
commitment by the bank holding company to a federal bank regulatory agency to
maintain the capital of a subsidiary bank will be assumed by the bankruptcy
trustee and entitled to a priority of payment.
 
     A depository institution by the FDIC can be held liable for any loss
incurred by, or reasonably expected to be incurred by, the FDIC after August 9,
1989, in connection with (i) the default of a commonly controlled FDIC-insured
depository institution or (ii) any assistance provided by the FDIC to a commonly
controlled FDIC-insured depository institution in danger of default. "Default"
is defined generally as the appointment of a conservator or receiver and "in
danger of default" is defined generally as the existence of certain conditions
indicating that a "default" is likely to occur in the absence of regulatory
assistance.
 
     Federal law (12 U.S.C. sec.55) permits the OCC to order the pro rata
assessment of shareholders of a national bank whose capital stock has become
impaired, by losses or otherwise, to relieve a deficiency in such national
bank's capital stock. This statute also provides for the enforcement of any such
pro rata assessment of shareholders of such national bank to cover such
impairment of capital stock by sale, to the extent necessary, of the capital
stock of any assessed shareholder failing to pay the assessment. Similarly, the
laws of certain states provide for such assessment and sale with respect to
banks chartered by such states. Norwest, as the sole shareholder of certain of
its subsidiary banks, is subject to such provisions.
 
CAPITAL REQUIREMENTS
 
     Under the Federal Reserve Board's risk-based capital guidelines for bank
holding companies, the minimum ratio of total capital to risk-adjusted assets
(including certain off-balance sheet items, such as stand-by letters of credit)
is 8%. At least half of the total capital is to be comprised of common stock,
minority interests, and noncumulative perpetual preferred stock ("Tier 1
capital"). The remainder ("Tier 2 capital") may consist of hybrid capital
instruments, perpetual debt, mandatory convertible debt securities, a limited
amount of subordinated debt, other preferred stock, and a limited amount of loan
and lease loss reserves. In addition, the Federal Reserve Board's final minimum
"leverage ratio" (the ratio of Tier 1 capital to quarterly average total assets)
guidelines for bank holding companies provide for a minimum leverage ratio of 3%
for bank holding companies that meet certain specified criteria, including that
they have the highest regulatory rating. All other bank holding companies will
be required to maintain a leverage ratio of 3% plus an additional cushion of 100
to 200 basis points. The guidelines also provide that banking organizations
experiencing internal growth or making acquisitions will be expected to maintain
strong capital positions substantially above the minimum supervisory levels,
without significant reliance on intangible assets. Furthermore, the guidelines
indicate that the Federal Reserve Board will continue to consider a "tangible
Tier 1 leverage ratio" in evaluating proposals for expansion or new activities.
The tangible Tier 1 leverage ratio is the ratio of a banking organization's Tier
1 capital, less all intangibles, to total assets, less all intangibles. Each of
Norwest's banking subsidiaries is also subject to capital requirements adopted
by applicable regulatory agencies which are substantially similar to the
foregoing. At June 30, 1994, Norwest's Tier 1 and total capital (the sum of Tier
1 and Tier 2 capital) to risk-adjusted assets ratios were 10.00% and 12.40%,
respectively, and Norwest's leverage ratio for the quarter ended June 30, 1994,
was 6.85%. Neither Norwest nor any subsidiary bank has been advised by the
appropriate federal regulatory agency of any specific leverage ratio applicable
to it.
 
FEDERAL DEPOSIT INSURANCE CORPORATION IMPROVEMENT ACT OF 1991
 
     In December 1991, Congress enacted the Federal Deposit Insurance
Corporation Improvement Act of 1991 ("FDICIA"), which substantially revised the
bank regulatory and funding provisions of the Federal Deposit Insurance Act and
makes revisions to several other federal banking statutes. Among other things,
FDICIA requires the federal banking regulators to take "prompt corrective
action" in respect of FDIC-insured depository institutions that do not meet
minimum capital requirements. FDICIA establishes five capital tiers: "well
capitalized," "adequately capitalized," "undercapitalized," significantly
undercapitalized," and "critically undercapitalized." Under applicable
regulations, an FDIC-insured depository institution is defined to be well
capitalized if it maintains a Leverage Ratio of at least 5%, a risk-adjusted
Tier 1 Capital Ratio of at least 6%, and a risk-adjusted Total Capital Ratio of
at least 10%, and is not subject to a directive, order, or written agreement to
meet and maintain specific capital levels. An insured depository institution is
 
                                       45
<PAGE>   50
 
defined to be adequately capitalized if it meets all of its minimum capital
requirements as described above. An insured depository institution will be
considered undercapitalized if it fails to meet any minimum required measure,
significantly undercapitalized if it has a risk-adjusted Total Capital Ratio of
less than 6%, risk-adjusted Tier 1 Capital Ratio of less than 3%, or a Leverage
Ratio of less than 3%, and critically undercapitalized if it fails to maintain a
level of tangible equity equal to at least 2% of total assets. An insured
depository institution may be deemed to be in a capitalization category that is
lower than is indicated by its actual capital position if it receives an
unsatisfactory examination rating.
 
     FDICIA generally prohibits a depository institution from making any capital
distribution (including payment of a dividend) or paying any management fee to
its holding company if the depository institution would thereafter be
undercapitalized. Undercapitalized depository institutions are subject to a wide
range of limitations on operations and activities, including growth limitations,
and are required to submit a capital restoration plan. The federal banking
agencies may not accept a capital plan without determining, among other things,
that the plan is based on realistic assumptions and is likely to succeed in
restoring the depository institution's capital. In addition, for a capital
restoration plan to be acceptable, the depository institution's parent holding
company must guarantee that the institution will comply with such capital
restoration plan. The aggregate liability of the parent holding company is
limited to the lesser of (i) an amount equal to 5% of the depository
institution's total assets at the time it became undercapitalized and (ii) the
amount which is necessary (or would have been necessary) to bring the
institution into compliance with all capital standards applicable with respect
to such institution as of the time it fails to comply with the plan. If a
depository institution fails to submit an acceptable plan, it is treated as if
it were significantly undercapitalized.
 
     Significantly undercapitalized depository institutions may be subject to a
number of requirements and restrictions, including orders to sell sufficient
voting stock to become adequately capitalized, requirements to reduce total
assets, and cessation of receipt of deposits from correspondent banks.
Critically undercapitalized institutions are subject to the appointment of a
receiver or conservator.
 
     FDICIA directs that each federal banking agency prescribe standards for
depository institutions and depository institution holding companies relating to
internal controls, information systems, internal audit systems, loan
documentation, credit underwriting, interest rate exposure, asset growth,
compensation, a maximum ratio of classified assets to capital, minimum earnings
sufficient to absorb losses, a minimum ratio of market value to book value for
publicly traded shares, and such other standards as the agency deems
appropriate. The FDIC, in consultation with the other federal banking agencies,
has adopted a final rule and guidelines with respect to external and internal
audit procedures and internal controls in order to implement those provisions of
FDICIA intended to facilitate the early identification of problems in financial
management of depository institutions. The FDIC has also issued proposed rules
prescribing standards relating to certain other of the management and
operational standards listed above. The full impact of such rule and guidelines
and proposed standards on Norwest cannot yet be ascertained.
 
     FDICIA also contains a variety of other provisions that may affect the
operations of Norwest, including new reporting requirements, revised regulatory
standards for real estate lending, "truth in savings" provisions, and the
requirement that depository institution give 90 days' notice to customers and
regulatory authorities before closing any branch.
 
     Under other regulations promulgated under FDICIA a bank cannot accept
brokered deposits (that is, deposits obtained through a person engaged in the
business of placing deposits with insured depository institutions or with
interest rates significantly higher than prevailing market rates) unless (i) it
is "well capitalized" or (ii) it is "adequately capitalized" and receives a
waiver from the FDIC. A bank is defined to be "adequately capitalized" if it
meets all of its minimum capital requirements. A bank that cannot receive
brokered deposits also cannot offer "pass-through" insurance on certain employee
benefit accounts, unless it provides certain notices to affected depositors. In
addition, a bank that is "adequately capitalized" and that has not received a
waiver from the FDIC may not pay an interest rate on any deposits in excess of
75 basis points over certain prevailing market rates. There are no such
restrictions on a bank that is "well capitalized." At June 30, 1994, all of
Norwest's banking subsidiaries were well capitalized and therefore were not
subject to these restrictions.

FDIC INSURANCE
 
     Effective January 1, 1993, the deposit insurance assessment rate for the
Bank Insurance Fund ("BIF") increased as part of the adoption by the FDIC of a
transitional risk-based assessment system. In June 1993, the FDIC published
final regulations making the transitional system permanent effective January 1,
1994, but left open the possibility that it may consider expanding the range
between the highest and lowest assessment rates at a later date. An
institution's risk category is based upon whether the institution is well
capitalized, adequately capitalized, or less than adequately capitalized. Each
insured depository institution is also to be assigned to one of the following
"supervisory subgroups": Subgroup A, B, or C. Subgroup A institutions are
financially sound institutions with few minor weaknesses; Subgroup B
institutions are institutions that demonstrate weaknesses which, if not
corrected, could result in significant deterioration; and Subgroup C
institutions are institutions for which there is a substantial probability that
the FDIC will suffer a loss in connection with the institution unless effective
action is taken to correct the areas of weakness. Based on its capital and
supervisory subgroups, each BIF member institution will be assigned an annual
FDIC assessment rate ranging from 0.23% per annum (for well capitalized Subgroup
A institutions) to 0.31% (for undercapitalized Subgroup C institutions).
Adequately capitalized institutions will be assigned assessment rates ranging
from 0.26% to 0.30%. Norwest incurred $72.4 million of FDIC insurance expense in
1993.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and
Board of Directors of
First National Bank of Kerrville:
 
     We have audited the accompanying consolidated balance sheets of First
National Bank of Kerrville and subsidiary (collectively, the Bank) as of
December 31, 1993 and 1992, 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 Bank'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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of First National Bank of
Kerrville and subsidiary as of December 31, 1993 and 1992, and the results of
their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles.

                FIRST NATIONAL BANK OF KERRVILLE AND SUBSIDIARY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1993 AND 1992, AND
                 INTERIM PERIOD ENDED JUNE 30, 1994 (UNAUDITED)
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
     The accounting and reporting policies of the First National Bank of
Kerrville (the Bank) conform to generally accepted accounting principles and to
general practices within the banking industry. A description of the more
significant of these policies follows.
 
     Interim Consolidated Financial Statements (Unaudited)
 
     The consolidated balance sheet as of June 30, 1994 and the related
consolidated statements of income, stockholders' equity and cash flows for the
six months ended June 30, 1994 and 1993, are unaudited and are not covered by
the report of independent public accountants. However, in the opinion of
management, these interim consolidated financial statements include all
adjustments (consisting of only normal recurring adjustments) which are
necessary for the fair presentation of the results for the interim periods
presented. The results of operations for the unaudited six-month period ended
June 30, 1994 are not necessarily indicative of the results which may be
expected for the entire 1994 fiscal year.
 
     Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Bank and
its wholly owned subsidiary, WNB Asset Management, Inc. All significant
intercompany accounts and transactions have been eliminated in consolidation.
 
     Investment Securities
 
     Investment securities are stated at cost, adjusted for the amortization of
premiums and the accretion of discounts, which are recognized on the effective
yield method as adjustments to interest income. Gains or losses on disposition
are based on the net proceeds and the adjusted carrying amount of the securities
sold, using the specific identification method.
 
     Temporary changes in the market value of investment securities are not
recognized since it is generally management's intention to hold such securities
to maturity. Investment securities held-for-sale represent those securities
specifically identified by management for disposition and are stated at the
lower of cost or market value. The estimated market value of investment
securities held-for-sale was $6,158,721 at December 31, 1992. The Bank had no
investment securities held-for-sale at December 31, 1993.
 
     In May, 1993, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 115, "Accounting for
Certain Investments in Debt and Equity Securities." SFAS No. 115 is effective
for financial statements issued for fiscal years beginning after December 15,
1993. The new standard requires the classification of securities into three
categories: held-to-maturity, available-for-sale or trading. Investments
classified as held-to-maturity are measured at amortized cost only if the
reporting enterprise has the positive intent and ability to hold those
securities to maturity. Securities that are bought and held principally for the
purpose of selling them in the near term shall be classified as trading
securities. Unrealized holding gains and losses shall be included in earnings.
Investments not classified as trading securities or held-to-maturity securities
shall be classified as available-for-sale. Securities that would be sold in
response to changes in market interest rates and the securities' prepayment
risk, needs for liquidity or changes in the availability and yield on
alternative investments are classified as available-for-sale. Unrealized holding
gains and losses shall be excluded from earnings and reported as a net amount in
a separate component of stockholders' equity (net of deferred taxes) until
realized. SFAS No. 115 was initially applied as of the beginning of the Bank's
fiscal year, January 1, 1994, and, in accordance with SFAS 115, was not applied
retroactively. The Bank had $90,291,332 of securities which were reflected as
available-for-sale as

                FIRST NATIONAL BANK OF KERRVILLE AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
                        DECEMBER 31, 1993 AND 1992, AND
                 INTERIM PERIOD ENDED JUNE 30, 1994 (UNAUDITED)
 
of January 1, 1994. These securities will be reported at fair value and any net
unrealized gains and losses recorded as a separate component of stockholder's
equity (net of deferred taxes). As of January 1, 1994, this classification
resulted in unrealized appreciation of $2,056,521. This was reflected as an
increase to available-for-sale securities of $2,056,521 and a corresponding
increase to stockholders' equity and deferred tax liabilities of $1,357,304 and
$699,217, respectively. As of June 30, 1994 (unaudited), the Bank had unrealized
holding losses of $805,546 reflected in the available-for-sale portfolio, a
corresponding decrease to stockholders' equity of $531,663, and a deferred tax
asset of $273,883.
 
     Loans
 
     Interest earned on commercial and real estate loans is accrued daily based
upon the principal amounts outstanding. Interest on installment loans is
recorded on the level-yield method. The recognition of income on a loan is
discontinued, and previously accrued interest is reversed, when interest or
principal payments become 90 days past due unless, in the opinion of management,
the outstanding principal and interest are both well secured and in process of
collection. Loans to customers whose financial conditions have deteriorated and
for which management has serious doubt as to the ability of the borrowers to
comply with their loan repayment terms are considered for nonaccrual status
whether or not the loans are 90 days or more past due. Subsequent cash payments
received are applied to the principal balance or recorded as interest income,
depending upon management's assessment of the ultimate collectibility of the
loan. If cash payments received relate to a loan previously charged off, in
whole or in part, payments not applied to the remaining principal balance are
recorded as recoveries.
 
     In May 1993, the FASB issued SFAS No. 114, "Accounting by Creditors for
Impairment of a Loan." SFAS No. 114 is effective for financial statements issued
for fiscal years beginning after December 15, 1994, although earlier adoption is
permitted. The new standard addresses the accounting by creditors for impairment
of certain loans, as well as the accounting for troubled debt restructurings. A
loan is impaired when, based on current information and events, it is probable
that a creditor will be unable to collect all amounts due according to the
contractual terms of the loan agreement. The standard requires that impaired
loans be measured based on the present value of expected future cash flows for
each loan discounted at the loan's effective interest rate or, as a practical
expedient, at the loan's observable market price or the fair value of the
collateral if the loan is collateral dependent. The Bank will adopt this
standard in 1995. Based on the loan portfolio as of June 30, 1994 (unaudited),
management believes the implementation of this standard will not have a material
effect on the Bank's financial position or results of operations.
 
     Allowance for Loan Losses
 
     The allowance for loan losses is established by a charge to income as a
provision for loan losses. Actual loan losses or recoveries are charged or
credited directly to this allowance. The provision for loan losses is based on
management's estimate of the amounts required to maintain an allowance adequate
to reflect losses inherent in the loan portfolio at the balance sheet date;
however, ultimate losses may vary from the current estimates. In estimating
losses, consideration is given to the financial condition of the borrower,
guarantor, current and anticipated economic conditions and collateral values.
These estimates are reviewed periodically, and adjustments to either increase or
decrease the allowance are reported in earnings in the period in which they
become known.
 
     Premises and Equipment
 
     Premises and equipment are stated at cost less accumulated depreciation.
Depreciation is calculated on the straight-line method over estimated useful
lives ranging from 5 to 40 years for building and improvements

and from 3 to 20 years for furniture and equipment. Repairs and maintenance are
charged to expense as incurred, and expenditures for renewals and betterments
which materially increase the value of the premises and equipment and have a
benefit over more than one accounting period are capitalized.
 
     Other Real Estate Owned
 
     Assets acquired, either formally (in full or partial settlement of loan
obligations) or through substantive foreclosure, are recorded at the lower of
the loan balance or estimated fair value. Additional writedowns for estimated
losses are subsequently provided when the carrying value of the real estate
exceeds its fair value less estimated selling costs. Subsequent write-downs are
reported in earnings in the period in which they become known. Other real estate
owned incudes loans of $815,034 at December 31, 1992, classified as in-substance
foreclosures." The Bank had no "in-substance foreclosures" at December 31, 1993.
 
     Federal Income Taxes
 
     In February 1992, the FASB issued SFAS No. 109, "Accounting for Income
Taxes," effective for fiscal years beginning after December 15, 1992. The new
standard allows the recognition of deferred tax assets and liabilities based on
the expected future tax consequences of existing differences between financial
reporting and tax reporting base of assets and liabilities and operating loss
and tax credit carry forwards for tax purposes. As of January 1, 1993, the new
standard was adopted by the Bank, and this change did not have a significant
impact on the Bank's financial position or results of operations.
 
     Recognition of Loan Origination Fees and Costs
 
     Loan origination and commitment fees paid by borrowers, net of loan
origination costs, are deferred and amortized as an adjustment to interest
income over the contractual life of the related loans using a method which
approximates the interest method. If a commitment expires unexercised, the
commitment fee is recognized as income.
 
     Fair Value of Financial Instruments
 
     In December 1991, the FASB issued SFAS No. 107, "Disclosures About Fair
Value of Financial Instruments." SFAS No. 107 requires all entities to disclose
the fair value of financial instruments, both assets and liabilities recognized
and not recognized in the balance sheet, for which it is practicable to estimate
fair value. The standard defines a financial instrument as cash, evidence of an
ownership in any entity, or a contract that conveys or imposes on an entity the
contractual right or obligation to either receive or deliver cash or another
financial instrument. Fair value is defined as the amount at which a financial
instrument could be exchanged in a current transaction between willing parties,
other than in a forced sale or liquidation, and is best evidenced by a quoted
market price if one exists.
 
     The following represents the methodology and assumptions used to estimate
the fair value of the Bank's financial instruments presented below. The Bank
operates as a going concern and, except for its investment securities portfolio,
no active market exists for its financial instruments. Much of the information
used to determine fair value is highly subjective and judgmental in nature and,
therefore, the results may not be precise. The subjective factors include, among
other things, estimates of cash flows, risk characteristics, credit quality and
interest rates, all of which are subject to change. Since the fair value is
estimated as of the balance sheet date, the amounts which will actually be
realized or paid upon sale, settlement or maturity of the various instruments
could be significantly different. Fair value estimates, methods and assumptions
for investment securities, loans, deposits and off balance sheet financial
instruments are set forth in the notes to the consolidated financial statements.

and payable and certain other assets and liabilities have been valued at their
respective carrying amounts due to their short-term nature.
 
     Reclassifications
 
     Certain reclassifications have been made to previously reported amounts to
make them consistent with current reporting.
 
2. STATEMENTS OF CASH FLOWS:
 
     For purposes of reporting cash flows, cash and cash equivalents include
cash and due from banks and federal funds sold. Generally, federal funds are
purchased and sold for one-day periods.
 
     Cash paid for interest was approximately $3,873,300, $4,889,000 and
$8,202,000 and cash paid for federal income taxes was approximately $1,364,000,
$1,372,000 and $212,000 during 1993, 1992 and 1991, respectively.
 
     Noncash transactions representing the transfer of other real estate owned
to performing loans totaled $2,110,324, $1,874,347 and $1,265,000 during 1993,
1992 and 1991, respectively. Noncash transactions representing the transfer of
nonperforming loans to other real estate owned were approximately $245,093,
$989,000 and $2,693,000 during 1993, 1992 and 1991, respectively.
 
3. INVESTMENT SECURITIES:
 
     The book value, amortized cost and market value of investment securities
available-for-sale and held-to-maturity, by type, together with unrealized
holding gains and losses as of June 30, 1994 (unaudited), are as follows:

     Expected maturities will differ from contractual maturities because
borrowers may have the right to call or prepay obligations with or without
prepayment penalties.
 
     Certain U.S. Government agency securities having book and estimated market
values of $5,701,519 and $6,158,721, respectively, were designated as
held-for-sale by the Bank as of December 31, 1992. During 1993, these
held-for-sale securities were sold for $5,884,758, resulting in a gain totaling
$459,517. The Bank had no other sales of investment securities in 1993. In June
1992, the Bank sold three U.S. Government agency securities for $860,089 at a
gain of $13,606. The sales of the fixed-rate U.S. Government agencies during
1993 and 1992 were made to restructure the investment portfolio into
variable-rate instruments in order to reduce the Bank's overall exposure to
interest rate risk. In all cases, the sales proceeds were immediately reinvested
in adjustable-rate instruments with extended maturities.
 
     In May 1994, the Bank sold U.S. Treasury Notes for $7,218,865, resulting in
a $247,302 gain. Sales proceeds were used to purchase fixed rate U.S. Government
agency securities which are maintained in the Bank's available-for-sale
portfolio.
 
     Investment securities having a par value of approximately $3,900,000 and
$7,593,000 at December 31, 1993 and 1992, respectively, were pledged to secure
public fund deposits and for other purposes required or permitted by law.
 
     Prior to December 31, 1993, the Bank purchased $4,588,821 of investment
securities and recorded such acquisition on the trade date. The settlement date
was subsequent to year-end when payment was made.
 
4. LOANS AND ALLOWANCE FOR LOAN LOSSES AND OTHER REAL ESTATE OWNED:
 
     The Bank grants commercial, real estate and installment loans to customers
primarily in Kerrville, Texas, and the surrounding area. Although the Bank has a
diversified loan portfolio, a substantial portion of its

     As of December 31, 1993 and 1992, the estimated fair value of the Bank's
net loan portfolio was approximately $97,238,000 and $75,793,000, respectively.
For purposes of determining the fair value of loans at December 31, 1993 and
1992, the loan portfolio was stratified into various homogeneous groupings
having like characteristics and maturities. Expected future cash flows were
discounted using a risk-free rate adjusted for certain factors which include
credit risk, prepayment risk and an expense and overhead component at year-end
for each grouping. The assigned discount rate may or may not be the contractual
rate in effect with the obligor. This discount rate is based on the U.S.
Treasury yield curve adjusted for credit risk, prepayment risk and expense and
overhead factors, which were determined using historical information.

     The allowance is maintained at a level which management considers to be
adequate to cover estimated losses inherent in the loan portfolio. The Bank's
methodology takes into consideration several factors in determining the level of
the allowance for loan losses. The components that comprise the allowance
include basically two areas: (a) specific allowances on loans and (b) a general
allowance based upon a historical moving average and amounts for factors which
are considered areas of additional risk.
 
     Management of the Bank assesses the adequacy of the allowance for loan
losses quarterly using a multistep procedure. First, loans are reviewed and
categorized as to potential risk based upon an internal grading system. Specific
allowances are then established for any loans with identified loss potential
after consideration of third-party appraisals of collateral value and management
assessments of current economic conditions, guarantor support, cash flows and
other circumstances, as appropriate. A general allowance is then determined
based upon the historical loss experience of the portfolio as a whole. These
estimates are based

upon historical data related to type of loan, risk assessment, historical loss
experience and other factors. Finally, the historical loss experience is
adjusted based on estimates of losses in the portfolio as a whole that cannot be
identified with specific loans, taking into consideration local and national
economic trends, volume of past due and seriously delinquent loans,
nonperforming loans, loan concentrations and other similar factors. These
considerations are not limited to previous collection experience and include
estimates of the effect of changing business trends and other environmental
conditions. As conditions are continually changing, it is necessary for
management to review the loan portfolio and market conditions quarterly and make
appropriate adjustments to the allowance. Management believes that the allowance
for loan losses at June 30, 1994 (unaudited), December 31, 1993 and 1992, was
adequate to cover expected losses based on economic circumstances known or
anticipated at that time.
 
     As of December 31, 1993, 1992 and 1991, interest income was not being
accrued on loans totaling approximately $2,022,000, $2,530,000 and $3,796,000,
respectively. If interest had been recognized at the stated or original rates,
interest income would have been increased by approximately $166,000 in 1993,
$209,000 in 1992, and $199,000 in 1991.
 
     As of December 31, 1993 and 1992, restructured loans totaled $928,689 and
$442,049, respectively. The effect on net interest income resulting from the
difference between the interest recognized on such loans and the interest that
would have been recognized at the original rate was $16,883 and $11,682,
respectively. Interest income recorded on such loans was approximately $71,000
and $36,000 for the years ended December 31, 1993 and 1992, respectively.
 
     Assets acquired, either formally (in full or partial settlement of loan
obligations) or through substantive foreclosure, are recorded in other real
estate owned upon foreclosure at the lower of the loan balance or estimated fair
value and totaled $2,606,322 and $5,052,470 at December 31, 1993 and 1992,
respectively. Subsequently, the assets are recorded at the lower of the new cost
basis established at foreclosure or fair market values less estimated selling
costs. Subsequent valuation adjustments are represented by an allowance against
the original basis in the foreclosed asset.
 
     An analysis of the allowance for foreclosed assets for the years ended
December 31, 1993, 1992 and 1991, follows:

     Time certificates of deposit of $100,000 and over aggregated approximately
$8,656,000 and $8,705,000 at December 31, 1993 and 1992, respectively. Interest
expense on time certificates of deposits was approximately $306,000 in 1993,
$451,000 in 1992, and $1,058,000 in 1991.
 
     Included in time deposits were time certificates of deposit with estimated
fair values of approximately $49,321,000 and $41,703,000 at December 31, 1993
and 1992, respectively. Expected future cash flows of time certificates of
deposit were discounted using current market rates at December 31, 1993 and
1992, for each grouping. The estimated fair value of demand deposits, NOW
accounts, savings and money market deposits and the remaining time deposits was
considered to approximate book value at December 31, 1993 and 1992, reflecting
the amount payable on demand at such date.
 
7. FEDERAL INCOME TAXES:
 
     As discussed in Note 1, the Bank adopted SFAS No. 109 as of the beginning
of 1993. Previously the Bank was using accounting Principles Bulletin No. 11,
"Accounting for Income Taxes," which deferred the tax effects of timing
differences between financial reporting and taxable income. Under SFAS No. 109,
deferred tax assets or liabilities are computed based on the difference between
the financial statement and income tax bases of assets and liabilities using the
enacted tax rates.

</TABLE>
 
     During 1992, the Bank wrote off $69,646 of deferred tax assets that could
not be recovered through carrybacks.
 
     In 1992, the Bank utilized approximately $848,000 in net operating loss
carryforwards for federal income tax purposes and reflected the related tax
benefit of $288,233 as an extraordinary item in the accompanying consolidated
financial statements.
 
     Deferred tax assets have increased at June 30, 1994, primarily due to the
accounting treatment for unrealized losses on the Bank's available-for-sale
investments, as required by SFAS No. 115.
 
8. RELATED-PARTY TRANSACTIONS:
 
     In the ordinary course of business, the Bank extends credit to certain
directors and executive officers of the Bank, and entities related to those
individuals, on substantially the same terms and conditions as for loans to
unrelated parties (see Note 4). Such loans amounted to approximately $1,555,000
and $1,570,000 at December 31, 1993 and 1992, respectively.
 
     The majority stockholder was paid approximately $159,000 and $151,000 in
consulting fees during 1993 and 1992, respectively.
 
9. COMMITMENTS AND CONTINGENCIES:
 
     In the normal course of business, there are various outstanding commitments
and contingent liabilities, such as commitments to extend credit, which are not
reflected in the accompanying financial statements. These instruments involve
elements of credit and interest rate risk in excess of the amounts recognized in
the

                 INTERIM PERIOD ENDED JUNE 30, 1994 (UNAUDITED)
 
balance sheets but are limited to their notional amounts. The Bank had
outstanding standby letters of credit of approximately $793,000 and $157,000 and
commitments to extend credit of approximately $10,537,000 and $5,634,000 as of
December 31, 1993 and 1992, respectively. The credit risks involved in these
instruments are essentially the same as those involved in extending loan
facilities to customers. The Bank uses the same credit policies in making
commitments and conditional obligations as it does for normal balance sheet
instruments. The Bank has provided for possible credit risk in these
transactions in its allowance for loan losses, as appropriate, and does not
anticipate losses in excess of such allowance as a result of these transactions.
The difference between the carrying values and the estimated fair values of
standby letters of credit and commitments to extend credit is not deemed to be
significant.
 
     The Bank is involved in legal actions that are in various stages of
litigation and investigation by the Bank and its legal counsel. Management
believes that the ultimate resolution of these matters will not have a material
adverse affect on the Bank's financial position or results of operations.
 
10. STOCKHOLDERS' EQUITY:
 
     During 1992, the board of directors of the Bank authorized the granting of
noncompensatory options to purchase 3,700 shares of common stock of the Bank
(the Options) to certain Bank officers. At December 31, 1993, 3,700 options were
outstanding having option prices of approximately $220 to $472 per share, all of
which are fully exercisable. The Options expire at defined periods following the
officers' terminations, but no later than October 30, 2002.
 
     The Office of the Comptroller of the Currency (OCC) and the Federal Deposit
Insurance Corporation (FDIC) have issued comprehensive guidelines implementing
risk-based capital requirements. The guidelines make regulatory capital
requirements more sensitive to differences in risk profiles among banking
organizations, take off balance sheet exposure into account in assessing capital
adequacy and encourage the holding of liquid, low-risk assets. Under these
guidelines, at December 31, 1993 and 1992, the Bank was required to maintain a
minimum ratio of total capital-to-risk-weighted assets of 8.0 percent of which
at least 4.0 percent must be in the form of Tier I capital. At June 30, 1994
(unaudited), December 31, 1993 and 1992, the percent of total
capital-to-risk-weighted assets was 18.3 percent, 16.4 percent and 17.2 percent,
respectively. The Bank's Tier I capital ratio as of June 30, 1994 (unaudited),
December 31, 1993 and 1992, was 17.1 percent, 15.1 percent and 15.9 percent,
respectively. Tier I leverage ratio is defined as a bank's Tier I capital
divided by its adjusted average total assets (net of allowance for losses). The
minimum leverage ratio is 3.0 percent for banking organizations carrying the
highest regulatory rating. Other institutions are expected to maintain a
leverage ratio of at least 4.0 percent to 5.0 percent depending upon their
particular condition. At June 30, 1994 (unaudited), December 31, 1993 and 1992,
the Bank's Tier I leverage ratio was 7.5 percent, 8.0 percent and 7.3 percent,
respectively.
 
11. ACQUISITION:
 
     On July 19, 1993, the Bank acquired all of the outstanding stock of the
Bank of Kerrville for approximately $4,774,000. The purchase price includes cash
paid to the previous owners of the Bank of Kerrville and other direct costs of
the acquisition. The acquisition has been accounted for under the purchase
method and, accordingly, the purchase price was allocated to the assets and
liabilities based on their fair market values at July 19, 1993. The operating
results of the Bank of Kerrville have been included in the consolidated
operating results since the date of acquisition. The Bank of Kerrville is a
state-chartered community bank located in Kerrville, Texas, with approximately
$52 million in total assets.
 
     The acquisition resulted in a core deposit intangible being recorded on the
books of the Bank. This intangible is being amortized over eight years.

                             PLAN OF REORGANIZATION
 
     AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") entered into as of
the 20th day of May, 1994, as amended and restated on July 8, 1994, by and
between First National Bank of Kerrville ("Kerrville"), a national banking
association, and NORWEST CORPORATION ("Norwest"), a Delaware corporation.
 
     WHEREAS, the parties hereto desire to effect a reorganization whereby a
wholly-owned subsidiary of Norwest ("Norwest Bank") will consolidate with
Kerrville (the "Consolidation") pursuant to an agreement of consolidation (the
"Consolidation Agreement") in substantially the form attached hereto as Exhibit
A, which provides, among other things, for the conversion and exchange of the
shares of Common Stock of Kerrville of the par value of $100 per share
("Kerrville Common Stock") outstanding immediately prior to the time the
Consolidation becomes effective in accordance with the provisions of the
Consolidation Agreement (the "Effective Time of the Consolidation") into shares
of voting Common Stock of Norwest of the par value of $1 2/3 per share ("Norwest
Common Stock"),
 
     NOW, THEREFORE, to effect such reorganization and in consideration of the
premises and the mutual covenants and agreements contained herein, the parties
hereto do hereby represent, warrant, covenant and agree as follows:
 
     1. BASIC PLAN OF REORGANIZATION
 
     (a) Consolidation. Subject to the terms and conditions contained herein, a
wholly-owned subsidiary of Norwest will be consolidated with Kerrville pursuant
to the Consolidation Agreement, with Kerrville as the surviving corporation, in
which consolidation each share of Kerrville Common Stock outstanding immediately
prior to the Effective Time of the Consolidation (other than shares as to which
statutory dissenters' appraisal rights have been exercised) will be converted
into and exchanged for a number of shares of Norwest Common Stock determined by
dividing the Norwest Shares (as defined below) by the number of shares of
Kerrville Common Stock outstanding immediately prior to the Effective Time of
the Consolidation. The "Norwest Shares" shall be equal to 1,225,000 reduced by
the amount determined by dividing (i) the Adjustment Amount, by (ii) Norwest
Measurement Price. The "Adjustment Amount" shall be an amount determined by (i)
adding together all amounts which immediately prior to the Effective Time of the
Consolidation Kerrville has paid and is obligated to pay in connection with a
judgment entered in the matter of Phoenix Founders, Inc. vs. First National Bank
of Kerrville, 3-92-CV-2309-J, in the U.S. District Court in Dallas, Texas (the
"Phoenix Matter"), including the amount of the judgment or settlement, accrued
interest thereon, costs assessed and attorneys fees of either party to the
Phoenix Matter, and then (ii) multiplying the result by 63.375%. The "Norwest
Measurement Price" is defined as the average of the closing prices of a share of
Norwest Common Stock as reported on the consolidated tape of the New York Stock
Exchange during the period of five (5) trading days ending at the end of the
third trading day immediately preceding the Closing Date (as defined below). If
the Phoenix Matter has not been finally resolved by the Closing Date, then a
number of shares equal to 1,225,000 less the Norwest Shares shall be deposited
into escrow in accordance with the terms of an escrow agreement to be entered
into by the parties after the date hereof (the "Escrow Agreement"). The Escrow
Agreement shall provide that shares held in escrow shall be distributed
proportionately to Norwest and the Kerrville shareholders based on amounts paid
by Kerrville to resolve the Phoenix Matter and shall provide further that if the
Phoenix Matter is not finally resolved within 42 months after the Closing Date,
such shares shall be distributed to Norwest.
 
     (b) Norwest Common Stock Adjustments. If between the date hereof and the
Effective Time of the Consolidation shares of Norwest 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
Norwest Common Stock into which a share of Kerrville Common Stock shall be
converted pursuant to subparagraph (a), above, will be appropriately and
proportionately adjusted so that the
 
                                       A-1
<PAGE>   73
 
number of such shares of Norwest Common Stock into which a share of Kerrville
Common Stock shall be converted will equal the number of shares of Norwest
Common Stock which holders of shares of Kerrville Common Stock would have
received pursuant to such reclassification, recapitalization, split-up,
combination, exchange of shares or readjustment, or stock dividend had the
record date therefor been immediately following the Effective Time of the
Consolidation.
 
     (c) Fractional Shares. No fractional shares of Norwest Common Stock and no
certificates or scrip certificates therefor shall be issued to represent any
such fractional interest, and any holder thereof shall be paid an amount of cash
equal to the product obtained by multiplying the fractional share interest to
which such holder is entitled by the average of the closing prices of a share of
Norwest Common Stock as reported by the consolidated tape of the New York Stock
Exchange for each of the five (5) trading days immediately preceding the
Effective Time of the Consolidation.
 
     (d) Mechanics of Closing Consolidation. Subject to the terms and conditions
set forth herein, the closing of the Consolidation will occur on a mutually
agreeable date, which date shall be not later than ten (10) business days
following the satisfaction or waiver of all conditions precedent set forth in
Sections 6 and 7 of this Agreement or on such other date as may be agreed to by
the parties (the "Closing Date"). Each of the parties agrees to use its best
efforts to cause the Consolidation to be completed as soon as practicable after
the receipt of final regulatory approval of the Consolidation and the expiration
of all required waiting periods. The Consolidation shall be effective at 11:59
p.m., Minneapolis, Minnesota time (the "Effective Time of the Consolidation") on
the date specified in the certificate of approval to be issued by the
Comptroller of the Currency of the United States, under the seal of his office,
approving the Consolidation (the "Effective Date of the Consolidation").
 
     The closing of the transactions contemplated by this Agreement and the
Consolidation Agreement (the "Closing") shall take place on the Closing Date at
the offices of Norwest, Norwest Center, Sixth and Marquette, Minneapolis,
Minnesota.
 
     2. REPRESENTATIONS AND WARRANTIES OF KERRVILLE. Kerrville represents and
warrants to Norwest as follows:
 
     (a) Organization and Authority. Kerrville is a national banking association
duly organized, validly existing and in good standing under the laws of the
United States, is duly qualified to do business and is in good standing in all
jurisdictions where its ownership or leasing of property or the conduct of its
business requires it to be so qualified and failure to be so qualified would
have a material adverse effect on Kerrville and the Kerrville Subsidiaries taken
as a whole and has corporate power and authority to own its properties and
assets and to carry on its business as it is now being conducted. Kerrville has
furnished Norwest true and correct copies of its articles of association and
by-laws, as amended.
 
     (b) Kerrville's Subsidiaries. Schedule 2(b) sets forth a complete and
correct list of all of Kerrville's subsidiaries as of the date hereof
(individually a "Kerrville Subsidiary" and collectively the "Kerrville
Subsidiaries"), all shares of the outstanding capital stock of each of which,
except as set forth on Schedule 2(b), are owned directly or indirectly by
Kerrville. No equity security of any Kerrville Subsidiary is or may be required
to be issued by reason of any option, warrant, scrip, right to subscribe to,
call or commitment of any character whatsoever relating to, or security or right
convertible into, shares of any capital stock of such subsidiary, and there are
no contracts, commitments, understandings or arrangements by which any Kerrville
Subsidiary is bound to issue additional shares of its capital stock, or any
option, warrant or right to purchase or acquire any additional shares of its
capital stock. Subject to 12 U.S.C. sec. 55 (1982), all of such shares so owned
by Kerrville are fully paid and nonassessable and are owned by it free and clear
of any lien, claim, charge, option, encumbrance or agreement with respect
thereto. Each Kerrville Subsidiary is a corporation or national banking
association duly organized, validly existing, duly qualified to do business and
in good standing under the laws of its jurisdiction of incorporation, and has
corporate power and authority to own or lease its properties and assets and to
carry on its business as it is now being conducted. Except as set forth on
Schedule 2(b), Kerrville does not own beneficially, directly or indirectly, more
than 5% of any class of equity securities or similar interests of any
corporation, bank, business trust, association or similar organization, and is
not, directly or indirectly, a partner in any partnership or party to any joint
venture.
 
                                       A-2
<PAGE>   74
 
     (c) Capitalization. The authorized capital stock of Kerrville consists of
50,000 shares of common stock, $100 par value, of which as of the close of
business on March 31, 1994, 25,000 shares were outstanding and no shares were
held in the treasury. The maximum number of shares of Kerrville Common Stock
(assuming for this purpose that phantom shares and other share-equivalents
constitute Kerrville Common Stock) that would be outstanding as of the Effective
Date of the Consolidation if all options, warrants, conversion rights and other
rights with respect thereto were exercised is 28,700. All of the outstanding
shares of capital stock of Kerrville have been duly and validly authorized and
issued and are fully paid and nonassessable. Except as set forth in Schedule
2(c), there are no outstanding subscriptions, contracts, conversion privileges,
options, warrants, calls or other rights obligating Kerrville or any Kerrville
Subsidiary to issue, sell or otherwise dispose of, or to purchase, redeem or
otherwise acquire, any shares of capital stock of Kerrville or any Kerrville
Subsidiary. Since March 31, 1994 no shares of Kerrville capital stock have been
purchased, redeemed or otherwise acquired, directly or indirectly, by Kerrville
or any Kerrville Subsidiary and no dividends or other distributions have been
declared, set aside, made or paid to the shareholders of Kerrville.
 
     (d) Authorization. Kerrville has the corporate power and authority to enter
into this Agreement and the Consolidation Agreement and, subject to any required
approvals of its shareholders, to carry out its obligations hereunder and
thereunder. The execution, delivery and performance of this Agreement and the
Consolidation Agreement by Kerrville and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by the Board of
Directors of Kerrville. Subject to such approvals of shareholders and of
government agencies and other governing boards having regulatory authority over
Kerrville as may be required by statute or regulation, this Agreement and the
Consolidation Agreement are valid and binding obligations of Kerrville
enforceable against Kerrville in accordance with their respective terms.
 
     Neither the execution, delivery and performance by Kerrville of this
Agreement or the Consolidation Agreement, nor the consummation of the
transactions contemplated hereby and thereby, nor compliance by Kerrville with
any of the provisions hereof or thereof, will (i) violate, conflict with, or
result in a breach of any provision of, or constitute a default (or an event
which, with notice or lapse of time or both, would constitute a default) under,
or result in the termination of, or accelerate the performance required by, or
result in a right of termination or acceleration of, or result in the creation
of, any lien, security interest, charge or encumbrance upon any of the
properties or assets of Kerrville or any Kerrville Subsidiary under any of the
terms, conditions or provisions of (x) its articles of incorporation or by-laws
or (y) any material note, bond, mortgage, indenture, deed of trust, license,
lease, agreement or other instrument or obligation to which Kerrville or any
Kerrville Subsidiary is a party or by which it may be bound, or to which
Kerrville or any Kerrville Subsidiary or any of the properties or assets of
Kerrville or any Kerrville Subsidiary may be subject, or (ii) subject to
compliance with the statutes and regulations referred to in the next paragraph,
to the best knowledge of Kerrville, violate any judgment, ruling, order, writ,
injunction, decree, statute, rule or regulation applicable to Kerrville or any
Kerrville Subsidiary or any of their respective properties or assets.
 
     Other than in connection or in compliance with the provisions of the
Securities Act of 1933 and the rules and regulations thereunder (the "Securities
Act"), the Securities Exchange Act of 1934 and the rules and regulations
thereunder (the "Exchange Act"), the securities or blue sky laws of the various
states or filings, consents, reviews, authorizations, approvals or exemptions
required under the BHC Act or the Hart-Scott-Rodino Antitrust Improvements Act
of 1976 ("HSR Act"), and filings required to effect the Consolidation under the
National Bank Act, no notice to, filing with, exemption or review by, or
authorization, consent or approval of, any public body or authority is necessary
for the consummation by Kerrville of the transactions contemplated by this
Agreement and the Consolidation Agreement.

<PAGE>   75
 
interim periods, to normal recurring adjustments) the consolidated financial
position of Kerrville and Kerrville's Subsidiaries at the dates and the
consolidated results of operations and cash flows of Kerrville and Kerrville's
Subsidiaries for the periods stated therein.
 
     (f) Reports. Since December 31, 1988, Kerrville and each Kerrville
Subsidiary has filed all reports, registrations and statements, together with
any required amendments thereto, that it was required to file with (i) the
Federal Reserve Board, (ii) the Federal Deposit Insurance Corporation (the
"FDIC"), (iii) the United States Comptroller of the Currency (the "Comptroller")
and (iv) any applicable state securities or banking authorities. All such
reports and statements filed with any such regulatory body or authority are
collectively referred to herein as the "Kerrville Reports". As of their
respective dates, the Kerrville Reports complied in all material respects with
all the rules and regulations promulgated by the Federal Reserve Board, the
FDIC, the Comptroller and applicable state securities or banking authorities, as
the case may be, and did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. Copies of all the Kerrville Reports have been
made available to Norwest by Kerrville. Kerrville is not required to file any
reports, registrations or statements with the Securities and Exchange Commission
(the "SEC").
 
     (g) Properties and Leases. Except as may be reflected in the Kerrville
Financial Statements and except for any lien for current taxes not yet
delinquent, Kerrville and each Kerrville Subsidiary have good title free and
clear of any material liens, claims, charges, options, encumbrances or similar
restrictions to all the real and personal property reflected in Kerrville's
consolidated balance sheet as of March 31, 1994 for the period then ended, and
all real and personal property acquired since such date, except such real and
personal property as has been disposed of in the ordinary course of business.
All leases of real property and all other leases material to Kerrville or any
Kerrville Subsidiary pursuant to which Kerrville or such Kerrville Subsidiary,
as lessee, leases real or personal property, which leases are described on
Schedule 2(g), are valid and effective in accordance with their respective
terms, and there is not, under any such lease, any material existing default by
Kerrville or such Kerrville Subsidiary or any event which, with notice or lapse
of time or both, would constitute such a material default. Substantially all
Kerrville's and each Kerrville Subsidiary's buildings and equipment in regular
use have been well maintained and are in good and serviceable condition,
reasonable wear and tear excepted.
 
     (h) Taxes. Each of Kerrville and the Kerrville Subsidiaries has filed all
federal, state, county, local and foreign tax returns, including information
returns, required to be filed by it, and paid or made adequate provision for the
payment of all taxes owed by it, including those with respect to income,
withholding, social security, unemployment, workers compensation, franchise, ad
valorem, premium, excise and sales taxes, and no taxes shown on such returns to
be owed by it or assessments received by it are delinquent. The federal income
tax returns of Kerrville and the Kerrville Subsidiaries for the fiscal year
ended December 31, 1989, and for all fiscal years prior thereto, are for the
purposes of routine audit by the Internal Revenue Service closed because of the
statute of limitations, and no claims for additional taxes for such fiscal years
are pending. Neither Kerrville nor any Kerrville Subsidiary is a party to any
pending action or proceeding, nor to Kerrville's knowledge is any such action or
proceeding threatened by any governmental authority, for the assessment or
collection of taxes, interest, penalties, assessments or deficiencies and no
issue has been raised by any federal, state, local or foreign taxing authority
in connection with an audit or examination of the tax returns, business or
properties of Kerrville or any Kerrville Subsidiary which has not been settled,
resolved and fully satisfied. Each of Kerrville and the Kerrville Subsidiaries
has paid all taxes owed or which it is required to withhold from amounts owing
to employees, creditors or other third parties. The consolidated balance sheet
as of December 31, 1993, referred to in paragraph 2(e) hereof, includes adequate
provision for all accrued but unpaid federal, state, county, local and foreign
taxes, interest, penalties, assessments or deficiencies of Kerrville and the
Kerrville Subsidiaries with respect to all periods through the date thereof.
 
     The Ownership Change, as defined in Section 382(g) of the Internal Revenue
Code of 1986, as amended (the "Code"), occurring as the result of the
acquisition of Bank of Kerrville by Corpus Christi National Bank, does not
subject that transaction to Section 382(l)(5) of the Code. None of Kerrville,
Corpus Christi National
 
                                       A-4
<PAGE>   76
 
Bank and Premier Bankshares of Texas, Inc. is a party to an election under
Regulation 1.1502-20(g)(5), promulgated under the Code, regarding the
acquisition of Bank of Kerrville by Kerrville.
 
     (i) Absence of Certain Changes. Since December 31, 1993, there has been no
change in the business, financial condition or results of operations of
Kerrville or any Kerrville Subsidiary, which has had, or may reasonably be
expected to have, a material adverse effect on the business, financial condition
or results of operations of Kerrville and the Kerrville Subsidiaries taken as a
whole.
 
     (j) Commitments and Contracts. Except as set forth on Schedule 2(j),
neither Kerrville nor any Kerrville Subsidiary is a party or subject to any of
the following (whether written or oral, express or implied):
 
          (i) any employment contract or understanding (including any
     understandings or obligations with respect to severance or termination pay
     liabilities or fringe benefits) with any present or former officer,
     director, employee or consultant (other than those which are terminable at
     will by Kerrville or such Kerrville Subsidiary);
 
          (ii) any plan, contract or understanding providing for any bonus,
     pension, option, deferred compensation, retirement payment, profit sharing
     or similar arrangement with respect to any present or former officer,
     director, employee or consultant;
 
          (iii) any labor contract or agreement with any labor union;
 
          (iv) any contract not made in the ordinary course of business
     containing covenants which limit the ability of Kerrville or any Kerrville
     Subsidiary to compete in any line of business or with any person or which
     involve any restriction of the geographical area in which, or method by
     which, Kerrville or any Kerrville Subsidiary may carry on its business
     (other than as may be required by law or applicable regulatory
     authorities);
 
          (v) any other contract or agreement which is a "material contract"
     within the meaning of Item 601(b)(10) of Regulation S-K; or
 
          (vi) any lease with annual rental payments aggregating $10,000 or
     more.
 
     (k) Litigation and Other Proceedings. Kerrville has furnished Norwest
copies of (i) all attorney responses to the request of the independent auditors
for Kerrville with respect to loss contingencies as of December 31, 1993 in
connection with the Kerrville financial statements, and (ii) a written list of
legal and regulatory proceedings filed against Kerrville or any Kerrville
Subsidiary since said date. Neither Kerrville nor any Kerrville Subsidiary is a
party to any pending or, to the best knowledge of Kerrville, threatened, claim,
action, suit, investigation or proceeding, or is subject to any order, judgment
or decree, except for matters which, in the aggregate, will not have, or cannot
reasonably be expected to have, a material adverse effect on the business,
financial condition or results of operations of Kerrville and the Kerrville
Subsidiaries taken as a whole.
 
     (l) Insurance. Kerrville and each Kerrville Subsidiary is presently
insured, and during each of the past five calendar years (or during such lesser
period of time as Kerrville has owned such Kerrville Subsidiary) has been
insured, for reasonable amounts with financially sound and reputable insurance
companies against such risks as companies engaged in a similar business would,
in accordance with good business practice, customarily be insured and has
maintained all insurance required by applicable law and regulation.
 
     (m) Compliance with Laws. Kerrville and each Kerrville Subsidiary has all
permits, licenses, authorizations, orders and approvals of, and has made all
filings, applications and registrations with, federal, state, local or foreign
governmental or regulatory bodies that are required in order to permit it to own
or lease its properties and assets and to carry on its business as presently
conducted and that are material to the business of Kerrville or such Kerrville
Subsidiary; all such permits, licenses, certificates of authority, orders and
approvals are in full force and effect and, to the best knowledge of Kerrville,
no suspension or cancellation of any of them is threatened; and all such
filings, applications and registrations are current. The conduct by Kerrville
and each Kerrville Subsidiary of its business and the condition and use of its
properties does not violate or infringe, in any respect material to any such
business, any applicable domestic (federal, state or
 
                                       A-5
<PAGE>   77
 
local) or foreign law, statute, ordinance, license or regulation. Neither
Kerrville nor any Kerrville Subsidiary is in default under any order, license,
regulation or demand of any federal, state, municipal or other governmental
agency or with respect to any order, writ, injunction or decree of any court.
Except for statutory or regulatory restrictions of general application, no
federal, state, municipal or other governmental authority has placed any
restriction on the business or properties of Kerrville or any Kerrville
Subsidiary which reasonably could be expected to have a material adverse effect
on the business or properties of Kerrville and the Kerrville Subsidiaries taken
as a whole.
 
     (n) Labor. No work stoppage involving Kerrville or any Kerrville Subsidiary
is pending or, to the best knowledge of Kerrville, threatened. Neither Kerrville
nor any Kerrville Subsidiary is involved in, or threatened with or affected by,
any labor dispute, arbitration, lawsuit or administrative proceeding which could
materially and adversely affect the business of Kerrville or such Kerrville
Subsidiary. Employees of Kerrville and the Kerrville Subsidiaries are not
represented by any labor union nor are any collective bargaining agreements
otherwise in effect with respect to such employees.
 
     (o) Material Interests of Certain Persons. To the best knowledge of
Kerrville no officer or director of Kerrville or any Kerrville Subsidiary, or
any "associate" (as such term is defined in Rule 14a-1 under the Exchange Act)
of any such officer or director, has any interest in any material contract or
property (real or personal), tangible or intangible, used in or pertaining to
the business of Kerrville or any Kerrville Subsidiary.
 
     Schedule 2(o) sets forth a correct and complete list of any loan from
Kerrville or any Kerrville Subsidiary to any present officer, director, employee
or any associate or related interest of any such person which was required under
Regulation O of the Federal Reserve Board to be approved by or reported to
Kerrville's or such Kerrville Subsidiary's Board of Directors.
 
     (p) Kerrville Benefit Plans.
 
          (i) The only "employee benefit plans" within the meaning of Section
     3(3) of the Employee Retirement Income Security Act of 1974, as amended
     ("ERISA"), for which Kerrville or any Kerrville Subsidiary currently acts
     as the plan sponsor as defined in ERISA Section 3(16)(B), and with respect
     to which any liability under ERISA or otherwise exists or may be incurred
     by Kerrville or any Kerrville Subsidiary are those set forth on Schedule
     2(p) (the "Plans"). No Plan is a "multi-employer plan" within the meaning
     of Section 3(37) of ERISA.
 
          (ii) Each Plan is and has been in all material respects operated and
     administered in accordance with its provisions and applicable law. Except
     as set forth on Schedule 2(p), Kerrville or the Kerrville Subsidiaries have
     received favorable determination letters from the Internal Revenue Service
     under the provisions of the Tax Equity and Fiscal Responsibility Act
     ("TEFRA"), the Deficit Reduction Act ("DEFRA") and the Retirement Equity
     Act ("REA") for each of the Plans to which the qualification requirements
     of Section 401(a) of the Code, apply. Kerrville knows of no reason that any
     Plan which is subject to the qualification provisions of Section 401(a) of
     the Code is not "qualified" within the meaning of Section 401(a) of the
     Code and that each related trust is not exempt from taxation under Section
     501(a) of the Code, except that any such Plan may not have been amended to
     comply with the Tax Reform Act of 1986 (the "TRA") and other recent
     legislation and regulations, although each such Plan is within the remedial
     amendment period during which retroactive amendment may be made.
 
          (iii) No Plan is subject to Title IV of ERISA nor is any Plan subject
     to the requirements of Section 412 of the Code.
 
          (iv) Except as disclosed in Schedule 2(p), and to the best knowledge
     of Kerrville, no Plan or any trust created thereunder, nor any trustee,
     fiduciary or administrator thereof, has engaged in a "prohibited
     transaction", as such term is defined in Section 4975 of the Code or
     Section 406 of ERISA or violated any of the fiduciary standards under Part
     4 of Title I of ERISA which could subject, to the best knowledge of
     Kerrville, such Plan or trust to the tax or penalty on prohibited
     transactions imposed by said Section 4975 or would result in material
     liability to Kerrville and the Kerrville Subsidiaries taken as a whole.
 
                                       A-6
<PAGE>   78
 
          (v) Except as set forth in Schedule 2(p), no Plan which is or was
     subject to Title IV of ERISA or any trust created thereunder has been
     terminated within the past six years, nor have there been any "reportable
     events" as that term is defined in Section 4043 of ERISA, with respect to
     any Plan, other than those events which may result from the transactions
     contemplated by this Agreement and the Consolidation Agreement.
 
          (vi) Except as set forth in Schedule 2(p), no Plan (including any Plan
     which was terminated within the past six years) or any trust created
     thereunder has incurred any "accumulated funding deficiency", as such term
     is defined in Section 412 of the Code (whether or not waived), since the
     effective date of ERISA.
 
          (vii) Except as disclosed in Schedule 2(p), neither the execution and
     delivery of this Agreement and the Consolidation Agreement nor the
     consummation of the transactions contemplated hereby and thereby will (i)
     result in any material payment (including, without limitation, severance,
     unemployment compensation, golden parachute or otherwise) becoming due to
     any director or employee or former employee of Kerrville or any Kerrville
     Subsidiary under any Plan or otherwise, (ii) materially increase any
     benefits otherwise payable under any Plan or (iii) result in the
     acceleration of the time of payment or vesting of any such benefits to any
     material extent.
 
     (q) Proxy Statement, etc. None of the information regarding Kerrville and
the Kerrville Subsidiaries supplied or to be supplied by Kerrville for inclusion
in (i) a Registration Statement on Form S-4 to be filed with the SEC by Norwest
for the purpose of registering the shares of Norwest Common Stock to be
exchanged for shares of Kerrville Common Stock pursuant to the provisions of the
Consolidation Agreement (the "Registration Statement"), (ii) the proxy statement
to be mailed to Kerrville's shareholders in connection with the meeting to be
called to consider the Consolidation (the "Proxy Statement") and (iii) any other
documents to be filed with the SEC or any regulatory authority in connection
with the transactions contemplated hereby or by the Consolidation Agreement
will, at the respective times such documents are filed with the SEC or any
regulatory authority and, in the case of the Registration Statement, when it
becomes effective and, with respect to the Proxy Statement, when mailed, be
false or misleading with respect to any material fact, or omit to state any
material fact necessary in order to make the statements therein not misleading
or, in the case of the Proxy Statement or any amendment thereof or supplement
thereto, at the time of the meeting of shareholders referred to in paragraph
4(c), be false or misleading with respect to any material fact, or omit to state
any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of any proxy for such meeting.
All documents which Kerrville and the Kerrville Subsidiaries are responsible for
filing with the SEC and any other regulatory authority in connection with the
Consolidation will comply as to form in all material respects with the
provisions of applicable law.
 
     (r) Registration Obligations. Neither Kerrville nor any Kerrville
Subsidiary is under any obligation, contingent or otherwise, which will survive
the Consolidation by reason of any agreement to register any of its securities
under the Securities Act.
 
     (s) Brokers and Finders. Neither Kerrville nor any Kerrville Subsidiary nor
any of their respective officers, directors or employees has employed any broker
or finder or incurred any liability for any financial advisory fees, brokerage
fees, commissions or finder's fees, and no broker or finder has acted directly
or indirectly for Kerrville or any Kerrville Subsidiary in connection with this
Agreement and the Consolidation Agreement or the transactions contemplated
hereby and thereby.
 
     (t) Administration of Trust Accounts. Kerrville and each Kerrville
Subsidiary has properly administered in all respects material and which could
reasonably be expected to be material to the financial condition of Kerrville
and the Kerrville 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. Neither
Kerrville, any Kerrville Subsidiary, nor any director, officer or employee of
Kerrville or any Kerrville Subsidiary 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
 
                                       A-7
<PAGE>   79
 
the financial condition of Kerrville and the Kerrville 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.
 
     (u) No Defaults. Neither Kerrville nor any Kerrville Subsidiary is in
default, nor has any event occurred which, with the passage of time or the
giving of notice, or both, would constitute a default, under any material
agreement, indenture, loan agreement or other instrument to which it is a party
or by which it or any of its assets is bound or to which any of its assets is
subject, the result of which has had or could reasonably be expected to have a
material adverse effect upon Kerrville and the Kerrville Subsidiaries, taken as
a whole. To the best of Kerrville's knowledge, all parties with whom Kerrville
or any Kerrville Subsidiary has material leases, agreements or contracts or who
owe to Kerrville or any Kerrville Subsidiary material obligations other than
with respect to those arising in the ordinary course of the banking business of
the Kerrville Subsidiaries are in compliance therewith in all material respects.
 
     (v) Environmental Liability. There is no legal, administrative, or other
proceeding, claim, or action of any nature seeking to impose, or that could
reasonably be expected to result in the imposition of, on Kerrville or any
Kerrville Subsidiary, any liability arising from the release of hazardous
substances under any local, state or federal environmental statute, regulation
or ordinance including, without limitation, the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended, pending or to the
best of Kerrville's knowledge, threatened against Kerrville or any Kerrville
Subsidiary the result of which has had or could reasonably be expected to have a
material adverse effect upon Kerrville and Kerrville's Subsidiaries taken as a
whole; to the best of Kerrville's knowledge there is no reasonable basis for any
such proceeding, claim or action; and to the best of Kerrville's knowledge
neither Kerrville nor any Kerrville Subsidiary is subject to any agreement,
order, judgment, or decree by or with any court, governmental authority or third
party imposing any such environmental liability.

warrants to Kerrville as follows:
 
     (a) Organization and Authority. Norwest is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware,
is duly qualified to do business and is in good standing in all jurisdictions
where its ownership or leasing of property or the conduct of its business
requires it to be so qualified and failure to be so qualified would have a
material adverse effect on Norwest and its subsidiaries taken as a whole and has
corporate power and authority to own its properties and assets and to carry on
its business as it is now being conducted. Norwest is registered as a bank
holding company with the Federal Reserve Board under the BHC Act.
 
     (b) Norwest Subsidiaries. Schedule 3(b) sets forth a complete and correct
list as of December 31, 1993, of Norwest's Significant Subsidiaries (as defined
in Regulation S-X promulgated by the SEC) (individually a "Norwest Subsidiary"
and collectively the "Norwest Subsidiaries"), all shares of the outstanding
capital stock of each of which, except as set forth in Schedule 3(b), are owned
directly or indirectly by Norwest. No equity security of any Norwest Subsidiary
is or may be required to be issued to any person or entity other than Norwest by
reason of any option, warrant, scrip, right to subscribe to, call or commitment
of any character whatsoever relating to, or security or right convertible into,
shares of any capital stock of such subsidiary, and there are no contracts,
commitments, understandings or arrangements by which any Norwest Subsidiary is
bound to issue additional shares of its capital stock, or options, warrants or
rights to purchase or acquire any additional shares of its capital stock.
Subject to 12 U.S.C. Section 55 (1982), all of such shares so owned by Norwest
are fully paid and nonassessable and are owned by it free and clear of any lien,
claim, charge, option, encumbrance or agreement with respect thereto. Each
Norwest Subsidiary is a corporation or national banking association duly
organized, validly existing, duly qualified to do business and in good standing
under the laws of its jurisdiction of incorporation, and has corporate power and
authority to own or lease its properties and assets and to carry on its business

Common Stock, $1 2/3 par value, of which as of the close of business on December
31, 1993, 294,131,670 shares were outstanding and 1,956,803 shares were held in
the treasury.
 
     (d) Authorization. Norwest has the corporate power and authority to enter
into this Agreement and to carry out its obligations hereunder. The execution,
delivery and performance of this Agreement by Norwest and the consummation of
the transactions contemplated hereby have been duly authorized by the Board of
Directors of Norwest. No approval or consent by the stockholders of Norwest is
necessary for the execution and delivery of this Agreement and the Consolidation
Agreement and the consummation of the transactions contemplated hereby and
thereby. Subject to such approvals of government agencies and other governing
boards having regulatory authority over Norwest as may be required by statute or
regulation, this Agreement is a valid and binding obligation of Norwest
enforceable against Norwest in accordance with its terms.
 
     Neither the execution, delivery and performance by Norwest of this
Agreement or the Consolidation Agreement, nor the consummation of the
transactions contemplated hereby and thereby, nor compliance by Norwest with any
of the provisions hereof or thereof, will (i) violate, conflict with, or result
in a breach of any provision of, or constitute a default (or an event which,
with notice or lapse of time or both, would constitute a default) under, or
result in the termination of, or accelerate the performance required by, or
result in a right of termination or acceleration of, or result in the creation
of, any lien, security interest, charge or encumbrance upon any of the
properties or assets of Norwest or any Norwest Subsidiary under any of the
terms, conditions or provisions of (x) its certificate of incorporation or
by-laws or (y) any material note, bond, mortgage, indenture, deed of trust,
license, lease, agreement or other instrument or obligation to which Norwest or
any Norwest Subsidiary is a party or by which it may be bound, or to which
Norwest or any Norwest Subsidiary or any of the properties or assets of Norwest
or any Norwest Subsidiary may be subject, or (ii) subject to compliance with the
statutes and regulations referred to in the next paragraph, to the best
knowledge of Norwest, violate any judgment, ruling, order, writ, injunction,
decree, statute, rule or regulation applicable to Norwest or any Norwest
Subsidiary or any of their respective properties or assets.
 
     Other than in connection with or in compliance with the provisions of the
Securities Act, the Exchange Act, the securities or blue sky laws of the various
states or filings, consents, reviews, authorizations, approvals or exemptions
required under the BHC Act or the HSR Act, and filings required to effect the
Consolidation under the National Bank Act, no notice to, filing with, exemption
or review by, or authorization, consent or approval of, any public body or
authority is necessary for the consummation by Norwest of the transactions
contemplated by this Agreement and the Consolidation Agreement.
 
     (e) Norwest Financial Statements. The consolidated statements of financial
condition of Norwest and Norwest's subsidiaries as of December 31, 1993 and 1992
and related consolidated statements of income, stockholders' equity and cash
flows for the three years ended December 31, 1993, together with the notes
thereto, certified by KPMG Peat Marwick and included in Norwest's Annual Report
on Form 10-K for the fiscal year ended December 31, 1993 as amended by Form
10-K/A filed May 13, 1994 (the "Norwest 10-K") as filed with the SEC, and the
unaudited consolidated balance sheets of Norwest and its subsidiaries as of
March 31, 1994 and the related unaudited consolidated statements of income and
cash flows for the three months then ended included in Norwest's Quarterly
Report on Form 10-Q for the fiscal quarter ended March 31, 1994, as filed with
the SEC (collectively, the "Norwest Financial Statements"), have been prepared
in accordance with generally accepted accounting principles applied on a
consistent basis and present fairly (subject, in the case of financial
statements for interim periods, to normal recurring adjustments) the
consolidated financial position of Norwest and its subsidiaries at the dates and
the consolidated results of operations, changes in financial position and cash
flows of Norwest and its subsidiaries for the periods stated therein.
 
     (f) Reports. Since December 31, 1993, Norwest and each Norwest Subsidiary
has filed all reports, registrations and statements, together with any required
amendments thereto, that it was required to file with (i) the SEC, including,
but not limited to, Forms 10-K, Forms 10-Q and proxy statements, (ii) the
Federal Reserve Board, (iii) the FDIC, (iv) the Comptroller and (v) any
applicable state securities or banking authorities. All such reports and
statements filed with any such regulatory body or authority are collectively
referred to herein as the "Norwest Reports". As of their respective dates, the
Norwest Reports complied in all
 
                                       A-9
<PAGE>   81
 
material respects with all the rules and regulations promulgated by the SEC, the
Federal Reserve Board, the FDIC, the Comptroller and any applicable state
securities or banking authorities, as the case may be, and did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading.
 
     (g) Properties and Leases. Except as may be reflected in the Norwest
Financial Statements and except for any lien for current taxes not yet
delinquent, Norwest and each Norwest Subsidiary has good title free and clear of
any material liens, claims, charges, options, encumbrances or similar
restrictions to all the real and personal property reflected in Norwest's
consolidated balance sheet as of March 31, 1994 included in Norwest's Quarterly
Report on Form 10-Q for the period then ended, and all real and personal
property acquired since such date, except such real and personal property has
been disposed of in the ordinary course of business. All leases of real property
and all other leases material to Norwest or any Norwest Subsidiary pursuant to
which Norwest or such Norwest Subsidiary, as lessee, leases real or personal
property, are valid and effective in accordance with their respective terms, and
there is not, under any such lease, any material existing default by Norwest or
such Norwest Subsidiary or any event which, with notice or lapse of time or
both, would constitute such a material default. Substantially all Norwest's and
each Norwest Subsidiary's buildings and equipment in regular use have been well
maintained and are in good and serviceable condition, reasonable wear and tear
excepted.
 
     (h) Taxes. Each of Norwest and the Norwest Subsidiaries has filed all
material federal, state, county, local and foreign tax returns, including
information returns, required to be filed by it, and paid or made adequate
provision for the payment of all taxes owed by it, including those with respect
to income, withholding, social security, unemployment, workers compensation,
franchise, ad valorem, premium, excise and sales taxes, and no taxes shown on
such returns to be owed by it or assessments received by it are delinquent. The
federal income tax returns of Norwest and the Norwest Subsidiaries for the
fiscal year ended December 31, 1979, and for all fiscal years prior thereto, are
for the purposes of routine audit by the Internal Revenue Service closed because
of the statute of limitations, and no claims for additional taxes for such
fiscal years are pending. Except only as set forth on Schedule 3(h), (i) neither
Norwest nor any Norwest Subsidiary is a party to any pending action or
proceeding, nor to Norwest's knowledge is any such action or proceeding
threatened by any governmental authority, for the assessment or collection of
taxes, interest, penalties, assessments or deficiencies which could reasonably
be expected to have any material adverse effect on Norwest and its subsidiaries
taken as a whole, and (ii) no issue has been raised by any federal, state, local
or foreign taxing authority in connection with an audit or examination of the
tax returns, business or properties of Norwest or any Norwest Subsidiary which
has not been settled, resolved and fully satisfied, or adequately reserved for.
Each of Norwest and the Norwest Subsidiaries has paid all taxes owed or which it
is required to withhold from amounts owing to employees, creditors or other
third parties.
 
     (i) Absence of Certain Changes. Since December 31, 1993, there has been no
change in the business, financial condition or results of operations of Norwest
or any Norwest Subsidiary which has had, or may reasonably be expected to have,
a material adverse effect on the business, financial condition or results of
operations of Norwest and its subsidiaries taken as a whole.
 
     (j) Commitments and Contracts. Except as set forth on Schedule 3(j), as of
April 1, 1994 neither Norwest nor any Norwest Subsidiary is a party or subject
to any of the following (whether written or oral, express or implied):
 
          (i) any labor contract or agreement with any labor union;
 
          (ii) any contract not made in the ordinary course of business
     containing covenants which materially limit the ability of Norwest or any
     Norwest Subsidiary to compete in any line of business or with any person or
     which involve any material restriction of the geographical area in which,
     or method by which, Norwest or any Norwest Subsidiary may carry on its
     business (other than as may be required by law or applicable regulatory
     authorities);
 
                                      A-10
<PAGE>   82
 
          (iii) any other contract or agreement which is a "material contract"
     within the meaning of Item 601(b)(10) of Regulation S-K.
 
     (k) Litigation and Other Proceedings. Neither Norwest nor any Norwest
Subsidiary is a party to any pending or, to the best knowledge of Norwest,
threatened, claim, action, suit, investigation or proceeding, or is subject to
any order, judgment or decree, except for matters which, in the aggregate, will
not have, or cannot reasonably be expected to have, a material adverse effect on
the business, financial condition or results of operations of Norwest and its
subsidiaries taken as a whole.
 
     (l) Insurance. Norwest and each Norwest Subsidiary is presently insured,
and during each of the past five calendar years (or during such lesser period of
time as Norwest has owned such Norwest Subsidiary) has been insured or
self-insured, for reasonable amounts with financially sound and reputable
insurance companies against such risks as companies engaged in a similar
business would, in accordance with good business practice, customarily be
insured and has maintained all insurance required by applicable law and
regulation.
 
     (m) Compliance with Laws. Norwest and each Norwest Subsidiary has all
permits, licenses, authorizations, orders and approvals of, and has made all
filings, applications and registrations with, federal, state, local or foreign
governmental or regulatory bodies that are required in order to permit it to own
or lease its properties or assets and to carry on its business as presently
conducted and that are material to the business of Norwest or such Subsidiary;
all such permits, licenses, certificates of authority, orders and approvals are
in full force and effect, and to the best knowledge of Norwest, no suspension or
cancellation of any of them is threatened; and all such filings, applications
and registrations are current. The conduct by Norwest and each Norwest
Subsidiary of its business and the condition and use of its properties does not
violate or infringe, in any respect material to any such business, any
applicable domestic (federal, state or local) or foreign law, statute,
ordinance, license or regulation. Neither Norwest nor any Norwest Subsidiary is
in default under any order, license, regulation or demand of any federal, state,
municipal or other governmental agency or with respect to any order, writ,
injunction or decree of any court. Except for statutory or regulatory
restrictions of general application, no federal, state, municipal or other
governmental authority has placed any restrictions on the business or properties
of Norwest or any Norwest Subsidiary which reasonably could be expected to have
a material adverse effect on the business or properties of Norwest and its
subsidiaries taken as a whole.
 
     (n) Labor. No work stoppage involving Norwest or any Norwest Subsidiary is
pending or, to the best knowledge of Norwest, threatened. Neither Norwest nor
any Norwest Subsidiary is involved in, or threatened with or affected by, any
labor dispute, arbitration, lawsuit or administrative proceeding which could
materially and adversely affect the business of Norwest or such Norwest
Subsidiary. Except as set forth on Schedule 3(j), employees of Norwest and the
Norwest Subsidiaries are not represented by any labor union nor are any
collective bargaining agreements otherwise in effect with respect to such
employees.
 
     (o) Norwest Benefit Plans.
 
          (i) As of the date hereof, the only "employee benefit plans" within
     the meaning of Section 3(3) of ERISA for which Norwest or any Norwest
     Subsidiary acts as plan sponsor as defined in ERISA Section 3(16)(B) with
     respect to which any liability under ERISA or otherwise exists or may be
     incurred by Norwest or any Norwest Subsidiary are those set forth on
     Schedule 3(o) (the "Norwest Plans"). No Norwest Plan is a "multi-employer
     plan" within the meaning of Section 3(37) of ERISA.
 
          (ii) Each Norwest Plan is and has been in all material respects
     operated and administered in accordance with its provisions and applicable
     law. Except as set forth on Schedule 3(o), Norwest or the Norwest
     Subsidiaries have received favorable determination letters from the
     Internal Revenue Service under the provisions of TEFRA, DEFRA and REA for
     each of the Norwest Plans to which the qualification requirements of
     Section 401(a) of the Code apply. Norwest knows of no reason that any
     Norwest Plan which is subject to the qualification provisions of Section
     401(a) of the Code is not "qualified" within the meaning of Section 401(a)
     of the Code and that each related trust is not exempt from taxation under
     Section 501(a) of the Code, except that any such Norwest Plan may not have
     been amended to comply with TRA and other recent legislation and
     regulations, although each such Norwest Plan is within the remedial
     amendment period during which retroactive amendment may be made.
 
                                      A-11
<PAGE>   83
 
          (iii) The present value of all benefits vested and all benefits
     accrued under each Norwest Plan which is subject to Title IV of ERISA did
     not, in each case, as determined for purposes of reporting on Schedule B to
     the Annual Report on Form 5500 of each such Norwest Plan for the plan year
     ending December 31, 1992, exceed the value of the assets of the Norwest
     Plans allocable to such vested or accrued benefits.
 
          (iv) Except as set forth on Schedule 3(o), and to the best knowledge
     of Norwest, no Norwest Plan or any trust created thereunder, nor any
     trustee, fiduciary or administrator thereof, has engaged in a "prohibited
     transaction", as such term is defined in Section 4975 of the Code or
     Section 406 of ERISA or violated any of the fiduciary standards under Part
     4 of Title I of ERISA, which could subject, to the best knowledge of
     Norwest, such Norwest Plan or trust to the tax or penalty on prohibited
     transactions imposed by said Section 4975 or would result in material
     liability to Norwest and its subsidiaries taken as a whole.
 
          (v) Except as set forth on Schedule 3(o), no Norwest Plan which is
     subject to Title IV of ERISA or any trust created thereunder has been
     terminated, nor have there been any "reportable events" as that term is
     defined in Section 4043 of ERISA with respect to any Norwest Plan, other
     than those events which may result from the transactions contemplated by
     this Agreement and the Consolidation Agreement.
 
          (vi) No Norwest Plan or any trust created thereunder has incurred any
     "accumulated funding deficiency", as such term is defined in Section 412 of
     the Code (whether or not waived), since the effective date of ERISA which
     would result in a material liability.
 
          (vii) Neither the execution and delivery of this Agreement and the
     Consolidation Agreement nor the consummation of the transactions
     contemplated hereby and thereby will (i) result in any material payment
     (including, without limitation, severance, unemployment compensation,
     golden parachute or otherwise) becoming due to any director or employee or
     former employee of Norwest under any Norwest Plan or otherwise, (ii)
     materially increase any benefits otherwise payable under any Norwest Plan

documents to be filed with the SEC or any regulatory authority in connection
with the transactions contemplated hereby or by the Consolidation Agreement
will, at the respective times such documents are filed with the SEC or any
regulatory authority and, in the case of the Registration Statement, when it
becomes effective and, with respect to the Proxy Statement, when mailed, be

knowledge, all parties with whom Norwest or any Norwest Subsidiary has material
leases, agreements or contracts or who owe to Norwest or any Norwest Subsidiary
material obligations other than with respect to those arising in the ordinary
course of the banking business of the Norwest Subsidiaries are in compliance
therewith in all material respects.

including, without limitation, the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended, pending or to the best of
Norwest's knowledge, threatened against Norwest or any Norwest Subsidiary, the
result of which has had or could reasonably be expected to have a material
adverse effect upon Norwest and its subsidiaries taken as a whole; to the best
of Norwest's knowledge there is no reasonable basis for any such proceeding,
claim or action; and to the best of Norwest's knowledge neither Norwest nor any
Norwest Subsidiary is subject to any agreement, order, judgment, or decree by or
with any court, governmental authority or third party imposing any such
environmental liability.

advisers in connection with this Agreement, with the same undertaking from such
professional advisers. If the transactions contemplated by this Agreement shall

Rule 145 under the Securities Act.
 
     (m) Kerrville shall establish such additional accruals and reserves as may
be necessary to conform Kerrville's accounting and credit loss reserve practices
and methods to those of Norwest and Norwest's plans with respect to the conduct

and expenses relating to the consummation by Kerrville of the Consolidation and
the other transactions contemplated by this Agreement.
 
     (n) Kerrville shall, within sixty (60) days of the date of this Agreement,
obtain and deliver to Norwest a written appraisal, by an appraiser acceptable to
Norwest, of the market value of a Merlin III N 23 AE airplane, Serial Number

Norwest, to sell the Airplane (or the stock of Kerrville's wholly-owned
subsidiary, WNB Management Company, if WNB Management Company holds title to the
Airplane and has no other assets at the Effective Date of the Consolidation)
effective as of the Effective Date of the Consolidation, at a cash purchase
price of not less than the appraised market value of the Airplane determined in
accordance with this subparagraph.
 
     (p) Kerrville shall take such actions as may be necessary to amend each
outstanding option to purchase Kerrville Common Stock ("Kerrville Option") which
remains unexercised in whole or in part at the Effective Time of the
Consolidation so that after the Effective Time of the Consolidation such
Kerrville Option shall become a fully-vested option to purchase the number of
shares of Norwest Common Stock determined by multiplying the aggregate number of
shares of Kerrville Common Stock subject to such option by 49. The option
exercise price for such converted option shall be determined by dividing the per
share Kerrville exercise price by 49.

("Kerrville Employees") shall be eligible for participation in the employee
welfare and pension plans of Norwest, as in effect from time to time, as
follows:
 
     (a) Employee Welfare Benefit Plans. Each Kerrville Employee (and, to the
extent any employee welfare benefit plans cover eligible dependents, the
eligible dependents of such Kerrville Employee) shall be eligible for
participation in the employee welfare benefit plans of Norwest listed below
subject to any eligibility requirements applicable to such plans and shall enter
each plan not later than the first day of the calendar quarter which begins at
least 32 days after the Effective Date of the Consolidation:
 
              Medical Plan
              Dental Plan
              Vision Plan
              Short Term Disability Plan
              Long Term Disability Plan
              Long Term Care Plan
              Flexible Benefits Plan
              Basic Group Life Insurance Plan
              Group Universal Life Insurance Plan
              Dependent Group Life Insurance Plan
              Business Travel Accident Insurance Plan
              Accidental Death and Dismemberment Plan
              Severance Pay Plan
              Vacation Program
 
     For the purpose of determining each Kerrville Employee's benefit for the
year in which the Consolidation occurs under the Norwest vacation program,
vacation taken by an employee of Kerrville in the year in which the
Consolidation occurs will be deducted from the total Norwest benefit. Each
Kerrville Employee shall be credited under the Norwest Medical Plan for
deductibles satisfied in the year in which the Consolidation occurs. Norwest
will waive the pre-existing condition limitations under the Norwest Medical Plan
and the Long Term Disability Plan but will not waive the pre-existing condition
limitations under the Long Term Care Plan. Until such time as the eligible
Kerrville Employees have entered the Norwest plans and programs listed above,
they shall continue to be covered by the comparable plans and programs, if any,
maintained by Kerrville, as such plans and programs are in effect as of the
Effective Date of the Consolidation, so that there shall be as little
interruption in time as possible in the transition from the Kerrville plans and
programs to the Norwest plans and programs.
 
     (b) Employee Pension Benefit Plans.
 
     Each Kerrville Employee shall be eligible for participation in the Norwest
Savings-Investment Plan (the "SIP"), subject to any eligibility requirements
applicable to the SIP (with full credit for years of past service to Kerrville
and the Kerrville Subsidiaries for the purpose of satisfying any eligibility and
vesting periods applicable to the SIP), and shall enter the SIP not later than
the first day of the calendar quarter which begins at least 32 days after the
Effective Date of the Consolidation. Until such time as the eligible Kerrville
Employees have entered the SIP, they shall continue to be covered by the First
National Bank of Kerrville 401(k) Plan, as such plan is in effect as of the
Effective Date of the Consolidation (the "401(k) Plan") so that there shall be
as little interruption in time as possible in the transition from coverage under
the 401(k) Plan to the SIP.
 
     Each Kerrville Employee shall be eligible for participation, as a new
employee, in the Norwest Pension Plan under the terms thereof.

                                   SECTION 3
 
AS OF THE EFFECTIVE DATE:
 
     3.1 Each share of Kerrville Common Stock outstanding immediately prior to
the Effective Time of the Consolidation (other than shares as to which statutory
dissenters' appraisal rights have been exercised) will be converted into and
exchanged for a number of shares of Norwest Common Stock determined by dividing
the Norwest Shares (as defined below) by the number of shares of Kerrville
Common Stock outstanding immediately prior to the Effective Time of the
Consolidation. The "Norwest Shares" shall be equal to 1,225,000 reduced by the
amount determined by dividing (i) the Adjustment Amount, by (ii) Norwest
Measurement Price. The "Adjustment Amount" shall be an amount determined by (i)
adding together all amounts which immediately prior to the Effective Time of the
Consolidation Kerrville has paid and is obligated to pay in connection with a
judgment entered in the matter of Phoenix Founders, Inc. vs. First National Bank
of Kerrville, 3-92-CV-2309-J, in the U.S. District Court in Dallas, Texas (the
"Phoenix Matter"), including the amount of the judgment or settlement, accrued
interest thereon, costs assessed and attorneys fees of either party to the
Phoenix Matter, and then (ii) multiplying the result by 63.375%. The "Norwest
Measurement Price" is defined as the average of the closing prices of a share of
Norwest Common Stock as reported on the consolidated tape of the New York Stock
Exchange during the period of five (5) trading days ending at the end of the
third trading day immediately preceding the Closing Date (as defined below). If
the Phoenix Matter has not been finally resolved by the Closing Date, then a
number of shares equal to 1,225,000 less the Norwest Shares shall be deposited
into escrow in accordance with the terms of an escrow agreement to be entered
into by the parties (the "Escrow Agreement"). The Escrow Agreement shall provide
that shares held in escrow shall be distributed proportionately to Norwest and
the Kerrville shareholders based on amounts paid by Kerrville to resolve the
Phoenix Matter and shall provide further that if the Phoenix Matter is not
finally resolved within 42 months after the Closing Date, such shares shall be
distributed to Norwest.

          (a) As soon as practicable after the merger becomes effective, each
     holder of a certificate for shares of Kerrville Common Stock outstanding
     immediately prior to the time of merger shall be entitled, upon surrender
     of such certificate for cancellation to Norwest Bank Minnesota, National
     Association, as the designated agent of the Consolidated Bank (the
     "Agent"), to receive a new certificate for the number of whole shares of
     Norwest Common Stock to which such holder shall be entitled on the basis
     above set forth. Until so surrendered each certificate which, immediately
     prior to the time of merger, represented shares of Kerrville Common Stock
     shall not be transferable on the books of the Consolidated Bank but shall
     be deemed (except for the payment of dividends as provided below) to
     evidence ownership of the number of whole shares of Norwest Common Stock
     into which such shares of Kerrville Common Stock have been converted on the
     basis above set forth; provided, however, that, until the holder of such
     certificate shall have surrendered the same for exchange as above set
     forth, no dividend payable to holders of record of Norwest Common Stock as
     of any date subsequent to the effective date of merger shall be paid to
     such holder with respect to the Norwest Common Stock represented by such
     certificate, but, upon surrender and exchange thereof as herein provided,
     there shall be paid by the Consolidated Bank or the Agent to the record
     holder of such certificate for Norwest Common Stock issued in exchange
     therefor an amount with respect to such shares of Norwest Common Stock
     equal to all dividends that shall have been paid or become payable to
     holders of record of Norwest Common Stock between the effective date of
     merger and the date of such exchange.
 
          (b) If between the date of the Reorganization Agreement and the
     Effective Time of the Consolidation (as defined in the Reorganization
     Agreement), shares of Norwest 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 (i) the number of shares of
     Norwest Common Stock into which a share of Kerrville Common Stock shall be
     converted on the basis above set forth, will be appropriately and
     proportionately adjusted so that the number of such shares of Norwest
     Common Stock into which a share of Kerrville Common Stock shall be
     converted will equal the number of shares of Norwest Common Stock which the
     holders of shares of Kerrville Common Stock would have received pursuant to
     such reclassification, recapitalization, split-up, combination, exchange of
     shares or readjustment, or stock dividend had the record date therefor been
     immediately following the Effective Time of the Consolidation and (ii) if a
     Norwest Common Stock Adjustment occurs between the date hereof and any date
     that the closing price of a share of Norwest Common Stock is used for
     purposes of this Agreement, the closing price of a share of Norwest Common
     Stock for such purposes shall be the sum of the closing prices on the date
     of each such determination of the number of shares of Norwest Common Stock
     and other securities, if any, (in each case as reported on the consolidated
     tape of the New York Stock Exchange on such date) issued with respect to
     one share of Norwest Common Stock as a result of the Norwest Common Stock
     Adjustment.
 
          (c) No fractional shares of Norwest Common Stock and no certificates
     or scrip certificates therefor shall be issued to represent any such
     fractional interest, and any holder of a fractional interest shall be paid
     an amount of cash equal to the product obtained by multiplying the
     fractional share interest to which such holder is entitled by the average
     of the closing prices of a share of Norwest Common Stock as reported by the
     consolidated tape of the New York Stock Exchange for each of the five (5)
     trading days immediately preceding the Effective Date of the Consolidation
     (as defined in the Reorganization Agreement).
 
     3.2 The shares of Interim Bank outstanding immediately prior to the time of
Consolidation shall be converted into and exchanged for       shares of the
Consolidated Bank, plus cash in the amount of $          .
 
     3.3 From and after the Effective Date, there shall be no transfers on the
stock transfer books of Consolidated Banks of the shares of Kerrville Common

Norwest Corporation
Norwest Center
Sixth and Marquette
Minneapolis, MN 55479-1026
 
Attn: Secretary
 
Gentlemen:
 
     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 First
National Bank of Kerrville, a national banking association ("Kerrville").
 
     Pursuant to an Agreement and Plan of Reorganization, dated as of
              , 1994, (the "Reorganization Agreement"), between Kerrville and
Norwest Corporation, a Delaware corporation ("Norwest") it is contemplated that
a wholly-owned subsidiary of Norwest will consolidate with Kerrville (the
"Consolidation") and as a result, I will receive in exchange for each share of
Common Stock, par value $100 per share, of Kerrville ("Kerrville Common Stock")
owned by me immediately prior to the Effective Time of the Consolidation (as
defined in the Reorganization Agreement), a number of shares of Common Stock,
par value $1 2/3 per share, of Norwest ("Norwest Common Stock"), as more
specifically set forth in the Reorganization Agreement.
 
     I hereby agree as follows:
 
     I will not offer to sell, transfer or otherwise dispose of any of the
shares of Kerrville Common Stock or Norwest Common Stock held by me during the
30 days prior to the Effective Time of the Consolidation.
 
     I will not offer to sell, transfer or otherwise dispose of any of the
shares of Norwest Common Stock issued to me pursuant to the Consolidation (the
"Stock") except (a) in compliance with the applicable provisions of Rule 145,
(b) in a transaction that is otherwise exempt from the registration requirements
of the Securities Act, or (c) in an offering registered under the Securities
Act.
 
     I will not sell, transfer or otherwise dispose of the Stock or in any way
reduce my risk relative to any shares of the Stock issued to me pursuant to the
Consolidation until such time as financial results covering at least 30 days of
post-Consolidation combined operations of Kerrville and Norwest have been
published.
 
     I consent to the endorsement of the Stock issued to me pursuant to the
Consolidation 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 Norwest Corporation 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."
 
     Norwest'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 is understood and agreed that this letter agreement shall terminate and
be of no further force and effect and the restrictive legend set forth above
shall be removed by delivery of substitute certificates without such legend, and
the related stop transfer restrictions shall be lifted forthwith, if (a) (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 Norwest and have been the beneficial owner of the Stock for at
least two
 
                                      A-30

years (or such other period as may be prescribed thereunder) and Norwest 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 twelve months,
or (iv) I am not and have not been for at least three months an affiliate of
Norwest and have been the beneficial owner of the Stock for at least three years
(or such other period as may be prescribed by the Securities Act, and the rules
and regulations promulgated thereunder), or (v) Norwest shall have received an
opinion of counsel acceptable to Norwest to the effect that the stock transfer
restrictions and the legend are not required, and (b) financial results covering
at least 30 days of post-Consolidation combined operations have been published.
 
     I have carefully read this letter agreement and the Reorganization
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 Kerrville.
 
                                          Sincerely,
 
                                          --------------------------------------

(B) LIABILITY OF CONSOLIDATED ASSOCIATION; CAPITAL STOCK; DISSENTING
    SHAREHOLDERS
 
     The consolidated association shall be liable for all liabilities of the
respective consolidating banks or associations. The capital stock of such
consolidated association shall not be less than that required under existing law
for the organization of a national bank in the place in which it is located:
Provided, That if such consolidation shall be voted for at such meetings by the
necessary majorities of the shareholders of each association and State bank
proposing to consolidate, and thereafter the consolidation shall be approved by
the Comptroller, any shareholder of any of the associations or State banks so
consolidated who has voted against such consolidation at the meeting of the
association or bank of which he is a stockholder or who has given notice in
writing at or prior to such meeting to the presiding officer that he dissents
from the plan of consolidation, shall be entitled to receive the value of the
shares so held by him when such consolidation is approved by the Comptroller
upon written request made to the consolidated association at any time before
thirty days after the date of consummation of the consolidation, accompanied by
the surrender of his stock certificates.
 
(C) VALUATION OF SHARES
 
     The value of the shares of any dissenting shareholder shall be ascertained,
as of the effective date of the consolidation, by an appraisal made by a
committee of three persons, composed of (1) one selected by the vote of the
holders of the majority of the stock, the owners of which are entitled to
payment in cash; (2) one selected by the directors of the consolidated banking
association; and (3) one selected by the two so selected. The valuation agreed
upon by any two of the three appraisers shall govern. If the value so fixed
shall not be satisfactory to any dissenting shareholder who has requested
payment, that shareholder may, within five days after being notified of the
appraised value of his shares, appeal to the Comptroller, who shall cause a
reappraisal to be made which shall be final and binding as to the value of the
shares of the appellant.
 
(D) APPRAISAL BY COMPTROLLER; EXPENSES OF CONSOLIDATED ASSOCIATION; SALE AND
    RESALE OF SHARES; STATE APPRAISAL AND CONSOLIDATION LAW
 
     If, within ninety days from the date of consummation of the consolidation,
for any reason one or more of the appraisers is not selected as herein provided,
or the appraisers fail to determine the value of such shares, the Comptroller
shall upon written request of any interested party cause an appraisal to be made
which shall be final and binding on all parties. The expenses of the Comptroller
in making the reappraisal or the appraisal, as the case may be, shall be paid by
the consolidated banking association. The value of the shares ascertained shall
be promptly paid to the dissenting shareholders by the consolidated banking
association. Within thirty days after payment has been made to all dissenting
shareholders as provided for in this section the shares of stock of the
consolidated banking association which would have been delivered to such
dissenting shareholders had they not requested payment shall be sold by the
consolidated banking association at an advertised public auction, unless some
other method of sale is approved by the Comptroller, and the consolidated
banking association shall have the rights to purchase any of such shares at such
public auction, if it is the highest bidder therefor, for the purpose of
reselling such shares within thirty days thereafter to such person or persons
and at such price not less than par as its board of directors by resolution may
determine. If the shares are sold at public auction at a price greater than the
amount paid to the dissenting shareholder the excess in such sale price shall be
determined in the manner prescribed by the law of the State in such cases,
rather than as provided in this section, if such provision is made in the State
law; and no such consolidation shall be in contravention of the law of the State
under which such bank is incorporated.

PURPOSE
 
     This banking circular informs all national banks of the valuation methods
used by the Office of the Comptroller of the Currency (OCC) to estimate the
value of a bank's shares when requested to do so by a shareholder dissenting to
the conversion, merger, or consolidation of its bank. The results of appraisals
performed by the OCC between January 1, 1985 and September 30, 1991 are also
summarized.
 
     References: 12 U.S.C. 214a, 215 and 215a; 12 CFR 11.590 (Item 2)
 
BACKGROUND
 
     Under 12 U.S.C. Sections 214a, a shareholder dissenting from a conversion,
consolidation, or merger involving a national bank is entitled to receive the
value of his or her shares from the resulting bank. A valuation of the shares
shall be made by a committee of three appraisers (a representative of the
dissenting shareholder, a representative of the resulting bank, and a third
appraiser selected by the other two). If the committee is formed and renders an
appraisal that is acceptable to the dissenting shareholder, the process is
complete and the appraised value of the shares is paid to the dissenting
shareholder by the resulting bank. If, for any reason, the committee is not
formed or if it renders an appraisal that is not acceptable to the dissenting
shareholder, an interested party may request an appraisal by the Office of the
Comptroller of the Currency (OCC). 12 U.S.C. Section 215 provides these
appraisal rights to any shareholder dissenting to a consolidation. Any
dissenting shareholder of a target bank in a merger is also entitled to these
appraisal rights pursuant to 12 U.S.C. Section 215a.
- --------------------------------------------------------------------------------
 
Date: March 5, 1992
 
     The above provides only a general overview of the appraisal process. The
specific requirements of the process are set forth in the statutes themselves.
 
METHODS OF VALUATION USED
 
     Through its appraisal process, the OCC attempts to arrive at a fair
estimate of the value of a bank's shares. After reviewing the particular facts
in each case and the available information on a bank's shares, the OCC selects
an appropriate valuation method, or combination of methods, to determine a
reasonable estimate of the shares' value.
 
     Market Value
 
     The OCC uses various methods to establish the market value of shares being
appraised. If sufficient trading in the shares exists and the prices are
available from direct quotes from the Wall Street Journal or a market-maker,
those quotes are considered in determining the market value. If no market value
is readily
 
                                       C-1
<PAGE>   107
 
available, or if the market value is not well established, other methods of
estimating market value can be used, such as the investment value and adjusted
book value methods.
 
     Investment Value
 
     Investment value requires an assessment of the value to investors of a
share in the future earnings of the target bank. Investment value is estimated
by applying an average price/earnings ratio of banks with similar earnings
potential to the earnings capacity of the target bank.
 
     The peer group selection is based on location, size, and earnings patterns.
If the state in which the subject bank is located provides a sufficient number
of comparable banks using location, size and earnings patterns as the criteria
for selection, the price/earnings ratios assigned to the banks are applied to
the earnings per share estimated for the subject bank. In order to select a
reasonable peer group when there are too few comparable independent banks in a
location that is comparable to that of the subject bank, the pool of banks from
which a peer group is selected is broadened by including one-bank holding
company banks in a comparable location, and/or by selecting banks in less
comparable locations, including adjacent states, that have earnings patterns
similar to the subject bank.
 
     Adjusted Book Value
 
     The OCC also uses an "adjusted book value" method for estimating value.
Historically, the OCC has not placed any weight on the bank's "unadjusted book
value", since the value is based on historical acquisition costs of the bank's
assets, and does not reflect investors' perceptions of the value of the bank as
an ongoing concern. Adjusted book value is calculated by multiplying the book
value of the target bank's assets per share times the average market price to
book value ratio of comparable banking organizations. The average market price
to book value ratio measures the premium or discount to book value which
investors attribute to shares of similarly situated banking organizations.
 
     Both the investment value method and the adjusted book value method present
appraised values which are based on the target bank's value as a going concern.
These techniques provide estimates of the market value of the shares of the
subject bank.
 
OVERALL VALUATION
 
     The OCC may use more than one of the above-described methods in deriving
the value of shares of stock. If more than one method is used, varying weights
may be applied in reaching an overall valuation. The weight given to the value
by a particular valuation method is based on how accurately the given method is
believed to represent market value. For example, the OCC may give more weight to
a market value representing infrequent trading by shareholders than to the value
derived from the investment value method when the subject bank's earnings trend
is so irregular that it is considered to be a poor predictor of future earnings.
 
PURCHASE PREMIUMS
 
     For mergers and consolidations, the OCC recognizes that purchase premiums
do exist and may, in some instances, be paid in the purchase of small blocks of
shares. However, the payment of purchase premiums depends entirely on the
acquisition or control plans of the purchasers, and such payment are not regular
or predictable elements of market value. Consequently, the OCC's valuation
methods do not include consideration of purchase premiums in arriving at the
value of shares.
 
STATISTICAL DATA
 
     The chart below lists the results of appraisals the OCC performed between
January 1, 1985 and September 30, 1991. The OCC provides statistical data on
book value and price/earnings ratios for comparative purposes, but does not
necessarily rely on such data in determining the value of the banks' shares.
Dissenting shareholders should not view these statistics as determinative for
future appraisals.
 
                                       C-2
<PAGE>   108
 
     In connection with disclosures given to shareholders under 12 CFR 11.590
(Item 2), banks may provide shareholders a copy of this banking circular or
disclose the information contained herein, including the past results of OCC
appraisals. If the bank discloses the past results of the OCC appraisals, it
should advise shareholders that: (1) the OCC did not rely on all the information
set forth in the chart in performing each appraisal; and (2) the OCC's past
appraisals are not necessarily determinative of its future appraisals of a
particular bank's shares.

ITEM 22. UNDERTAKINGS
 
     (a) The undersigned registrant hereby undertakes:
 
          (1) To file, during any period, in which offers or sales are being
     made, a post-effective amendment to this registration statement (i) to
     include any prospectus required by Section 10(a)(3) of the Securities Act
     of 1933, (ii) to reflect in the prospectus any facts or events arising
     after the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement, and (iii) to include any material information with
     respect to the plan of distribution not previously disclosed in the
     registration statement or any material change to such information in the
     registration statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such posteffective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     (c) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     (d) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer, or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer, or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     (f) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     (g) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

Norwest Center
Sixth and Marquette
Minneapolis, Minnesota  55479-1000

Ladies and Gentlemen:

         In connection with the proposed registration under the Securities Act
of 1933, as amended, of 1,465,000 shares of the common stock (the "Shares"),
par value $1 2/3 per share, of Norwest Corporation (the "Corporation"), a
Delaware corporation, which are proposed to be issued by the Corporation in
connection with the consolidation (the "Consolidation") of a wholly owned
subsidiary of the Corporation with First National Bank of Kerrville, a national
banking association, I have examined such corporate records and other
documents, including the Registration Statement on Form S-4 relating to the
Shares and have reviewed such matters of law as I have deemed necessary for
this opinion, and I advise you that in my opinion:

         1.  The Corporation is a corporation duly organized and existing under
the laws of the State of Delaware.

         2.  All necessary corporate action on the part of the Corporation has
been taken to authorize the issuance of the Shares in connection with the
Consolidation, and, when issued as described in the Registration Statement, the
Shares will be legally and validly issued, fully paid, and nonassessable.

         I consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                           Very truly yours,




                                           /s/ Stanley S. Stroup

representations set forth below.

NORWEST

  Norwest is a Delaware corporation with its principal office at Sixth and
Marquette, Minneapolis, Minnesota 55479.  Norwest maintains its books on an
accrual method of accounting and uses the calendar year as its taxable year.
Norwest is registered as a bank holding company with the Federal Reserve Board.

  Norwest is authorized to issue (i) 5,000,000 shares of Preferred Stock,
without par value, of which as of the close of business on December 31, 1993,
1,131,250 shares of 10.24% Cumulative Preferred Stock at $100 stated value and
1,143,750 shares of Cumulative Convertible Preferred Stock, Series B, at $200
stated value, were outstanding and (ii) 500,000,000 shares of Common Stock,
$1-2/3 par value, of which as of the close of business on December 31, 1993,
294,131,670 shares were outstanding.  The Norwest Common Stock is widely-held
and publicly traded on the New York Stock Exchange and the Chicago Stock
Exchange.


INTERIM BANK

  Norwest Interim Bank Kerrville, National Association ("Interim Bank") is a
national banking association and a wholly-owned subsidiary of Norwest
incorporated for the sole purpose of the Consolidation.


THE CONSOLIDATION

  The Reorganization Agreement and the Agreement and Plan of Consolidation
between Interim Bank and Kerrville (the "Consolidation Agreement") attached as
Exhibit A to the Reorganization Agreement provide for the consolidation of
Interim Bank with Kerrville under the charter of Kerrville, pursuant to the
authority of and in accordance with the provisions of section 215 of the
National Bank Act, 12 U.S.C. Section  215.  As of the Effective Date of the
Consolidation, the corporate existences of Kerrville and Interim Bank shall be
consolidated into Kerrville as the "Consolidated Bank", and all rights,
franchises, and interests of Kerrville and Interim Bank shall be vested in the
Consolidated Bank by virtue of the Consolidation.

  As of the Effective Date, each share of Kerrville Common Stock outstanding
immediately prior to the Effective Time of the Consolidation (other than shares
as to which statutory dissenters' appraisal rights have been exercised) will be
converted into and exchanged for a number of shares of Norwest Common Stock
determined by dividing the Norwest Shares by the number of shares of Kerrville
Common Stock outstanding immediately prior to the Effective Time of the
Consolidation.  The "Norwest Shares" shall be equal to 1,225,000 reduced by the
amount determined by dividing the Adjustment Amount by the Norwest Measurement
Price.
<PAGE>   3
First National Bank of Kerrville

Page 3


The "Adjustment Amount" is an amount equal to 63.375 percent of the amounts
which Kerrville has paid and is obligated to pay in connection with a judgment
entered in certain litigation referred to as the Phoenix Matter, and the
"Norwest Measurement Price" is the average of the closing prices of a share of
Norwest Common Stock on the New York Stock Exchange during the period of five
trading days ending at the end of the third trading day immediately preceding
the Closing Date.  If the Phoenix Matter has not been finally resolved by the
Closing Date, then a number of shares equal to 1,225,000 less the Norwest
Shares shall be deposited into escrow in accordance of the terms of an escrow
agreement to be entered into by the parties (the "Escrow Agreement").  The
Escrow Agreement shall provide that shares held in escrow shall be distributed
proportionately to Norwest and the Kerrville shareholders based on amounts paid
by Kerrville to resolve the Phoenix Matter and shall provide further that if
the Phoenix Matter is not finally resolved within 42 months after the Closing
Date, such shares shall be distributed to Norwest.

  The shares of Interim Bank outstanding immediately prior to the Effective
Time of the Consolidation shall be converted into and exchanged for shares of
the Consolidated Bank, plus cash.

  No fractional shares of Norwest Common Stock shall be issued; in lieu
thereof, any holder of a fractional interest shall be paid an amount of cash
equal to the product obtained by multiplying the fractional share interest to
which such holder is entitled by the average of the closing prices of a share
of Norwest Common Stock on the New York Stock Exchange for each of the five
trading days immediately preceding the Effective Date of the Consolidation.

  Section 10 of the Reorganization Agreement provides that all expenses in
connection with that Agreement and the transactions contemplated thereby,
including without limitation legal and accounting fees, incurred by Kerrville
and Kerrville subsidiaries shall be borne by Kerrville, and all such expenses
incurred by Norwest shall be borne by Norwest.

  In Section 5(c) of the Reorganization Agreement, Norwest agrees to file with
the Securities and Exchange Commission a registration statement relating to the
shares of Norwest Common Stock to be delivered to the shareholders of Kerrville
pursuant to the Consolidation Agreement, and to use its best efforts to cause
the registration statement to become effective.  In Section 5(d) of the
Reorganization Agreement, Norwest agrees to file all documents required to be
filed to list the Norwest Common Stock to be issued pursuant to the
Consolidation Agreement on the New York Stock Exchange and the Chicago Stock
Exchange and to use its best efforts to effect such listings.

  In Section 4(n) of the Reorganization Agreement, Kerrville agrees that it
will use its best efforts to sell an airplane owned by Kerrville at a cash
purchase price of not less than its appraised market value.

BUSINESS PURPOSE

  The terms of the Reorganization Agreement were the result of arm's-length
negotiations between representatives of Kerrville and Norwest.

  The Consolidation will enable Kerrville to become part of a larger and more
diverse banking organization thereby enabling Kerrville to offer a broader
range of services to its customers.  Norwest's continued expansion in the Texas
banking market through its acquisition of Kerrville will result in Kerrville's
becoming another example of a sound and attractive banking operation for
Norwest and enable Norwest to acquire other banking operations in the state.


                                REPRESENTATIONS

  In connection with  your request that we furnish this opinion, certain
representations have been made with respect to the existence of certain facts.
These constitute material representations relied upon by us as a basis for our
opinion, and our opinion is conditioned upon the initial and continuing
accuracy of these representations.  Specifically, it has been represented that:

  1. There is no plan or intention by any shareholder of Kerrville who owns one
percent or more of the Kerrville Common Stock, and to the best of the knowledge
of the management of Kerrville there is no plan or intention on the part of the
remaining shareholders of Kerrville, to sell, exchange or otherwise dispose of
a number of shares of Norwest Common Stock to be received by them in the
Consolidation that would reduce the Kerrville shareholders' ownership of
Norwest Common Stock to a number of shares having a value, as of the date of
the Consolidation, of less than 50 percent of the value of all of the formerly
outstanding Kerrville Common Stock as of the date of the Consolidation.  For
purposes of this representation, shares of Kerrville Common Stock exchanged for
cash or other property, surrendered by dissenters or exchanged for cash in lieu
of fractional shares of Norwest Common Stock will be treated as outstanding
Kerrville Common Stock on the date of the Consolidation.

  2. Following the Consolidation, Kerrville will hold at least 90 percent of
the fair market value of its net assets and at least 70 percent of the fair
market value of its gross assets and at least 90 percent of the fair market
value of Interim Bank's net assets and at least 70 percent of the fair market
value of Interim Bank's gross assets held immediately prior to the
Consolidation.  For purposes of this representation, amounts paid by Kerrville
or Interim Bank to dissenters, amounts paid by Kerrville or Interim Bank to
shareholders who receive cash or other property, amounts used by Kerrville or
Interim Bank to pay reorganization expenses, and all redemptions and
distributions (except for regular, normal dividends) made by Kerrville will
<PAGE>   5
First National Bank of Kerrville
_________, 1994
Page 5


be included as assets of Kerrville or Interim Bank, respectively, immediately
prior to the Consolidation.

  3. Kerrville has no plan or intention to issue additional shares of its stock
that would result in Norwest's losing control of Kerrville within the meaning
of section 368(c) of the Internal Revenue Code of 1986 (the "Code").

  4. Norwest has no plan or intention to reacquire any of the Norwest Common
Stock issued in the Consolidation.

  5. Norwest has no plan or intention to liquidate Kerrville, to merge
Kerrville with or into another corporation, to sell or otherwise dispose of the
stock of Kerrville, or to cause Kerrville to sell or otherwise dispose of any
of its assets or of any of the assets acquired from Interim Bank except for
dispositions made in the ordinary course of business.

  6. Interim Bank will have no liabilities assumed by Kerrville and will not
transfer to Kerrville any assets subject to liabilities in the Consolidation.

7. Following the Consolidation, Kerrville will continue its historic business.

  8. Norwest, Interim Bank, Kerrville and the Kerrville shareholders will pay
their respective expenses, if any, incurred in connection with the
Consolidation.

  9. There is no intercorporate indebtedness existing between Norwest and
Kerrville or between Interim Bank and Kerrville that was issued, acquired, or
will be settled at a discount.

  10.  Norwest does not own, nor has it owned during the past five years, any
shares of the stock of Kerrville.

  11.  Neither Kerrville nor Norwest is an investment company as defined in
section 368(a)(2)(F)(iii) and (iv) of the Code.

  12.  Kerrville is not under the jurisdiction of a court in a title 11 or
similar case within the meaning of section 368(a)(3)(A) of the Code.

  13.  The total amount of cash to be received by shareholders of Kerrville
Common Stock in lieu of fractional shares of Norwest Common Stock will not
exceed one percent of the total fair market value of the Norwest Common Stock
(as of the date of the Consolidation) that will be issued in the Consolidation.

  14.  None of the compensation to be received by any shareholder-employees of
Kerrville will be separate consideration for, or allocable to, any of their
shares of Kerrville
<PAGE>   6

Page 6


Common Stock; none of the shares of Norwest Common Stock to be received by any
shareholder-employees will be separate consideration for, or allocable to, any
employment agreement; and the compensation to be paid to any
shareholder-employees will be for services actually rendered and will be
commensurate with the amounts paid to third parties bargaining at arm's-length
for similar services.

  15.  The shares of Norwest Common Stock to be placed in escrow pursuant to
the Escrow Agreement (the "Escrowed Shares") will appear as issued and
outstanding on the balance sheet of Norwest and will be legally outstanding
under applicable corporate law.

  16.  All dividends paid on the Escrowed Shares will be distributed currently
to the Kerrville shareholders.

  17.  All voting rights of the Escrowed Shares will be exercisable by or on
behalf of the Kerrville shareholders or their authorized agent.

  18.  At least 50 percent of the number of shares of Norwest Common Stock to
be issued in the Consolidation will not be subject to the Escrow Agreement.

  Our opinion is further conditioned upon our understanding that the
transactions contemplated by the Reorganization Agreement will be carried out
strictly in accordance with the terms of the Reorganization Agreement and that
there are no other agreements, arrangements, or understandings among any of
Kerrville, Norwest, Interim Bank or the Kerrville shareholders other than those
described or referenced in the Reorganization Agreement.


                            STATEMENT OF AUTHORITIES

  Section 368(a)(1)(A) of the Code defines a "reorganization" to include a
statutory merger or consolidation.  Section 368(a)(2)(E) provides that a
transaction otherwise qualifying under section 368(a)(1)(A) shall not be
disqualified by reason of the fact that stock of a corporation (referred to as
the "controlling corporation") which before the merger was in control of the
merged corporation is used in the transaction, if (i) after the transaction,
the corporation surviving the merger holds substantially all of its properties
and of the properties of the merged corporation (other than stock of the
controlling corporation distributed in the transaction), and (ii) in the
transaction, former shareholders of the Surviving Corporation exchanged, for an
amount of voting stock of the controlling corporation, an amount of stock in
the Surviving Corporation which constitutes control of such corporation.

  Treas. Reg. Section  1.368-2(j) provides that section 368(a)(2)(E) of the
Code does not apply to a consolidation.  However, in Revenue Ruling 84-104,
1984-2 Cum. Bull. 94, the Internal Revenue Service held that a "consolidation"
pursuant to section 215 of the National Bank Act 
<PAGE>   7
First National Bank of Kerrville
_________, 1994
Page 7

of a wholly-owned bank subsidiary of a bank holding company with an existing 
national banking association is considered a merger, rather than a 
consolidation, for federal income tax purposes because under section 215 of 
the National Bank Act one of the combining corporations survives the 
transaction and no new corporation is formed.  Accordingly, a consolidation 
pursuant to section 215 of the National Bank Act can qualify as a reverse 
triangular merger for purposes of section 368(a)(1)(A) and (a)(2)(E) of the 
Code.

  Section 368(b) of the Code provides that the term "a party to a
reorganization" includes both corporations, in the case of a reorganization
resulting from the acquisition by one corporation of stock or properties of
another, and that in the case of a reorganization qualifying under section
368(a)(1)(A) by reason of section 368(a)(2)(E), also includes the controlling
corporation referred to in section 368(a)(2)(E).  Section 368(c) provides that
the term "control" means the ownership of stock possessing at least 80 percent
of the total combined voting power of all classes of stock entitled to vote and
at least 80 percent of the total number of shares of all other classes of stock
of the corporation.

  Section 368(a)(2)(F) of the Code provides generally that if two or more
parties to a transaction described in section 368(a)(1) were investment
companies (as defined in section 368(a)(2)(F)(iii) and (iv)) immediately before
the transaction, then the transaction shall not be considered to be a
reorganization with respect to any such investment company (and its
shareholders).  Section 368(a)(3) provides additional rules with respect to the
reorganization of a corporation in a title 11 or similar case.

  Section 354(a)(1) of the Code provides that no gain or loss shall be
recognized if stock or securities in a corporation a party to a reorganization
are, in pursuance of the plan of reorganization, exchanged solely for stock or
securities in such corporation or in another corporation a party to the
reorganization.

  Section 358(a)(1) of the Code provides that in the case of an exchange to
which section 354 applies, the basis of the property permitted to be received
under such section without the recognition of gain or loss shall be the same as
that of the property exchanged.

  Section 1223(1) of the Code provides in part that in determining the period
for which the taxpayer has held property received in an exchange, there shall
be included the period for which he held the property exchanged if the property
has, for the purpose of determining gain or loss from a sale or exchange, the
same basis in whole or in part in his hands as the property exchanged and the
property exchanged at the time of such exchange was a capital asset as defined
in section 1221 of the Code.

  Treas. Reg. Section  1.368-1(b) provides that requisite to a reorganization
under the Code are a continuity of the business enterprise under the modified
corporate form and a continuity of interest therein on the part of those
persons who, directly or indirectly, were the owners of the enterprise prior to
the reorganization.
<PAGE>   8
First National Bank of Kerrville

  Treas. Reg. Section  1.368-1(d) provides that continuity of business
enterprise requires that the acquiring corporation either (i) continue the
historic business of the acquired corporation or (ii) use a significant portion
of the acquired corporation's historic business assets in a business, and that
the continuity of business enterprise requirement is satisfied if the acquiring
corporation continues the acquired corporation's historic business.

  In Revenue Ruling 67-275, 1967-2 Cum. Bull. 142, pursuant to a plan of
reorganization, an acquiring corporation paid the costs necessary to register
with the Securities and Exchange Commission the stock issued to the
shareholders of the acquired corporation, in order to promote the orderly
marketing of the acquiring corporation's stock by enabling the shareholders of
the acquired corporation to deal with such stock in the same manner as other
shareholders of the acquiring corporation.  It was ruled that the costs of
registering its own stock are properly attributable to the acquiring
corporation and are not other property received in the reorganization by the
shareholders of the acquired corporation.

  In Revenue Procedure 77-37, 1977-2 Cum. Bull. 568, the Internal Revenue
Service published operating rules used in considering requests for rulings
involving reorganizations.  Section 3.02 of Revenue Procedure 77-37 provides
that the "continuity of interest" requirement of Treas.  Reg. Section
1.368-1(b) is satisfied if there is continuing interest through stock ownership
in the acquiring corporation (or a corporation in control thereof) on the part
of the former shareholders of the acquired corporation which is equal in value,
as of the effective date of the reorganization, to at least 50% of the value of
all of the formerly outstanding stock of the acquired corporation as of the
same date.  Sales, redemptions, and other dispositions of stock occurring prior
or subsequent to the plan of reorganization will be considered in determining
whether there is a 50% continuing interest through stock ownership as of the
effective date of the reorganization.  Revenue Procedure 77-37, by its terms,
does not define, as a matter of law, the lower limits of continuity of
interest.  See, e.g., John A. Nelson Co. v. Helvering, 296 U.S. 374 (1935);
Helvering v. Minnesota Tea Co., 296 U.S. 378 (1935); Miller v. Commissioner, 84
F.2d 415 (6th Cir. 1936); and United States v.  Adkins-Phelps, Inc., 400 F.2d
737 (8th Cir. 1968).

  In Revenue Procedure 77-41, 1977-2 Cum. Bull. 574, the Internal Revenue
Service stated that rulings would usually be issued under section 302(a) of the
Code that cash to be distributed to shareholders in lieu of fractional share
interests in corporate reorganizations will be treated as having been received
in part or full payment in exchange for the stock redeemed if the cash
distribution is undertaken solely for the purpose of saving the corporation the
expense and inconvenience of issuing and transferring fractional shares, and is
not separately bargained-for consideration.

  In Revenue Procedure 86-42, 1986-2 Cum. Bull. 722, the Internal Revenue
Service set forth standard representations to be submitted as a prerequisite to
the issuance of rulings on the tax consequences of a reorganization described
in section 368(a)(1)(A) and section 368(a)(2)(E)

of the Code, which to the extent relevant are substantially the same as the
representations set forth in the Reorganization Agreement as described above.
In Revenue Procedure 90-56, 1990-2 Cum. Bull. 639, the Internal Revenue Service
stated that it will no longer issue advance rulings on whether a transaction
constitutes a corporate reorganization within the meaning of section
368(a)(1)(A) of the Code, but did not revoke Revenue Procedure 86-42 or Revenue
Procedure 77-41.

  In Revenue Procedure 84-42, 1984-1 Cum. Bull. 521, the Internal Revenue
Service stated that in reorganization transactions a portion of the stock
issued in exchange for the requisite stock or property may be placed in escrow
by the exchanging shareholders for possible return to the issuing corporation
under specified conditions provided:  (i) there is a valid business reason for
establishing the arrangement; (ii) the stock subject to such arrangement
appears as issued and outstanding on the balance sheet of the issuing
corporation and such stock is legally outstanding under applicable state law;
(iii) all dividends paid on such stock will be distributed currently to the
exchanging shareholders; (iv) all voting rights of such stock are exercisable
by or on behalf of the shareholders or their authorized agent; (v) no shares of
such stock are subject to restrictions requiring their return to the issuing
corporation because of death, failure to continue employment, or similar
restrictions; (vi) all such stock is released from the arrangement within five
years from the date of consummation of the transaction (except where there is a
bona fide dispute as to whom the stock should be released); (vii) at least 50
percent of the number of shares of each class of stock issued initially to the
shareholders is not subject to the arrangement; (viii) the return of stock will
not be triggered by an event the occurrence or nonoccurrence of which is within
the control of shareholders; (ix) the return of stock will not be triggered by
the payment of additional tax or reduction in tax paid as a result of an audit
by the Internal Revenue Service of the shareholders or the corporation; and (x)
the mechanism for calculation of the number of shares of stock to be returned
is objective and readily ascertainable.

                                  CONCLUSIONS

  It is our opinion that the Consolidation constitutes a statutory
consolidation under section 215 of the National Bank Act.

  Accordingly, based upon the facts and representations set forth above, the
authorities and ruling policies of the Internal Revenue Service discussed above
as applied to those facts and representations, and conditioned upon the initial
and continuing accuracy of the representations set forth above, it is our
opinion that:

   (i)   The Consolidation will constitute a reorganization within the meaning
  of section 368(a) of the Code, and Kerrville, Norwest and Interim Bank will
  each be a party to the reorganization within the meaning of section 368(b) of
  the Code.

   (ii)  No gain or loss will be recognized by the holders of Kerrville Common
  Stock upon the receipt of shares of Norwest Common Stock in exchange for
  shares of Kerrville Common Stock, except that a holder of Kerrville Common
  Stock who receives cash in lieu of a fractional share interest in Norwest
  Common Stock will recognize gain or loss equal to the difference between such
  cash and the basis allocated to the fractional share interest.

   (iii)  The basis of the shares of Norwest Common Stock (including fractional
  share interests treated as received and shares placed in escrow) received by
  a holder of Kerrville Common Stock will be the same as the basis of the
  shares of Kerrville Common Stock exchanged therefor.

   (iv)  The holding period of the shares of Norwest Common Stock received by a
  holder of Kerrville Common Stock will include the holding period of the
  shares of Kerrville Common Stock exchanged therefor, provided the Kerrville
  Common Stock is held as a capital asset at the Effective Time of the
  Consolidation.


  We express no opinion as to the tax treatment of the Consolidation under the
provisions of any other sections of the Code which also may be applicable
thereto or to the tax treatment of any conditions existing at the time of, or
effects resulting from, the transactions which are not specifically addressed
in the foregoing opinion.

  This opinion is given to you by us solely for your use and is not to be
quoted or otherwise referred to or furnished to any governmental agency (other
than to the Securities and Exchange Commission as an exhibit to the
registration statement relating to the shares of Norwest Common Stock to be
issued pursuant to the Consolidation or to the Internal Revenue Service in
connection with an examination of the transactions contemplated by the
Reorganization Agreement) or to other persons without our prior written
consent.

  We hereby consent to the use of our name under "Certain Federal Income Tax
Consequences" in the Proxy Statement-Prospectus of Norwest and the filing of a
copy of this opinion as an exhibit to the Norwest Registration Statement.
