                                                                  May 9, 1997
Dear Shareholder:

        A special meeting of shareholders of The First National Bankshares, Inc.
("FNB") will be held on June 11, 1997 to approve the Agreement and Plan of
Reorganization dated January 17, 1997 (the "Reorganization Agreement") between
FNB and Norwest Corporation ("Norwest") and the related Agreement and Plan of
Merger dated April 28, 1997 (the "Plan of Merger"). The Reorganization Agreement
and Plan of Merger provide for the merger of a wholly-owned subsidiary of
Norwest with and into FNB (the "Merger"). FNB, as the surviving corporation in
the Merger, will become a wholly-owned subsidiary of Norwest.

    If the Reorganization Agreement and Plan of Merger are approved and the
Merger becomes effective, you will be entitled to receive shares of Norwest
common stock in exchange for shares of FNB common stock owned by you immediately
prior to the Merger. The number of shares of Norwest common stock you will be
entitled to receive (the "exchange ratio") will be determined in accordance with
the formula set forth in the Reorganization Agreement. The formula is based on
the average closing prices of a share of Norwest common stock, as reported on
the New York Stock Exchange during the 20 trading day period ending on the last
trading day before the special meeting.

    Enclosed with this letter are a notice of special meeting, which sets forth
the time and location of the special meeting, and a Proxy Statement-Prospectus,
which describes in more detail the terms and conditions of the Merger. Please
carefully review and consider the information in the Proxy Statement-Prospectus.
Copies of the Reorganization Agreement and the Plan of Merger are included in
the Proxy Statement-Prospectus as Appendix A and Appendix B, respectively.
Additional information concerning Norwest, including its most recent annual
report on Form 10-K, may be obtained from Norwest as indicated in the Proxy
Statement-Prospectus under the section entitled "Incorporation of Certain
Documents by Reference."

    FNB's board of directors has approved the Reorganization Agreement and the
Plan of Merger as being advisable and in your best interests as a shareholder of
FNB and RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE REORGANIZATION AGREEMENT
AND PLAN OF MERGER.

    YOUR VOTE IS IMPORTANT. Please mark, date, sign and return the enclosed
proxy in the enclosed postage prepaid envelope as soon as possible, regardless
of whether you plan to attend the special meeting. A failure to vote, either by
not returning the enclosed proxy or by checking the "Abstain" box thereon, will
have the same effect as a vote against approval of the Reorganization Agreement
and the Plan of Merger. If you attend the meeting, you may vote in person if you
wish, even though you have previously returned your proxy.

                                                 H. Barton Jones

                      THE FIRST NATIONAL BANKSHARES, INC.
                                PROXY STATEMENT
                     FOR A SPECIAL MEETING OF SHAREHOLDERS

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

                              NORWEST CORPORATION
                                  PROSPECTUS
                            SHARES OF COMMON STOCK

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

        This Proxy Statement-Prospectus is being provided to you in connection
with the solicitation of your proxy by the board of directors of The First
National Bankshares, Inc. ("FNB") for use at a special meeting of FNB's
shareholders to be held on June 11, 1997 (the "Special Meeting"). FNB's board of
directors has called the Special Meeting to approve the Agreement and Plan of
Reorganization dated January 17, 1997 (the "Reorganization Agreement") between
FNB and Norwest Corporation ("Norwest") and the related Agreement and Plan of
Merger dated April 28, 1997 (the "Plan of Merger").

    The Reorganization Agreement and Plan of Merger provide for the merger of a
wholly-owned subsidiary of Norwest with and into FNB (the "Merger"). FNB, as the
surviving corporation in the Merger, will become a wholly-owned subsidiary of
Norwest. If the Reorganization Agreement and Plan of Merger are approved and the
Merger becomes effective, you will be entitled to receive shares of Norwest
common stock, par value $1-2/3 per share ("Norwest Common Stock"), in exchange
for your shares of FNB common stock, par value $1.00 per share ("FNB Common
Stock").

    The number of shares of Norwest Common Stock you will be entitled to receive
in the Merger in exchange for your shares of FNB Common Stock (the "exchange
ratio") will be determined in accordance with the formula set forth in the
Reorganization Agreement. The exchange ratio formula is based on the average of
the closing prices of a share of Norwest Common Stock, as reported on the New
York Stock Exchange during the 20 trading day period ending on the last trading
day before the Special Meeting. (This average is referred to as the "Norwest
Measurement Price.") The full exchange ratio formula is described in
"SUMMARY--The Merger--Exchange Ratio" and "THE MERGER--Merger Consideration."
The formula operates in the following manner:

    (1) If the Norwest Measurement Price is equal to or greater than $40.25,
        then the exchange ratio will be 10.165--that is, you will be entitled to
        receive 10.165 shares of Norwest Common Stock for each share of FNB
        Common Stock owned by you.

    (2) If the Norwest Measurement Price is equal to or less than $36.25, then
        the exchange ratio will be 11.287--that is, you will be entitled to
        receive 11.287 shares of Norwest Common Stock for each share of FNB
        Common Stock owned by you.

    (3) If the Norwest Measurement Price is less than $40.25 and more than
        $36.25, then the exchange ratio will equal the number obtained by
        dividing 409.14 by the Norwest Measurement Price. For example, if the
        Norwest Measurement Price is $38, then the exchange ratio would equal
        409.14 divided by $38, or 10.767. In this example, you would receive
        10.767 shares of Norwest Common Stock for each share of FNB Common Stock
        owned by you.

The closing price of a share of Norwest Common Stock on the effective date of
the Merger may be higher or lower than the Norwest Measurement Price.

        Copies of the Reorganization Agreement and Plan of Merger are included
in this Proxy Statement-Prospectus as Appendix A and Appendix B, respectively,
and are incorporated herein by reference. For purposes of the remainder of this
document, unless otherwise indicated or the context otherwise requires,
references to the Reorganization Agreement will be deemed to include the Plan of
Merger.

        Norwest Common Stock trades on the NYSE and the Chicago Stock Exchange
("CHX") under the symbol NOB. The closing price of Norwest Common Stock as
reported on the NYSE Composite Tape on May __, 1997 was $______ per share. There
is no established market for FNB Common Stock.

        In addition to serving as the proxy statement of FNB in connection with
the Special Meeting, this document constitutes the prospectus of Norwest
covering the shares of Norwest Common Stock to be issued in the Merger.

        NORWEST, ITS BANKING SUBSIDIARIES AND MANY OF ITS NONBANKING
SUBSIDIARIES ARE SUBJECT TO EXTENSIVE REGULATION BY A NUMBER OF FEDERAL AND
STATE AGENCIES. THIS REGULATION MAY AFFECT, AMONG OTHER THINGS, NORWEST'S
EARNINGS AND/OR RESTRICT ITS ABILITY TO PAY DIVIDENDS ON NORWEST COMMON STOCK.
SEE "CERTAIN REGULATORY AND OTHER CONSIDERATIONS PERTAINING TO NORWEST."

        THE SHARES OF NORWEST COMMON STOCK OFFERED BY THIS PROXY
STATEMENT-PROSPECTUS ARE NOT SAVINGS ACCOUNTS, DEPOSITS OR OTHER OBLIGATIONS OF
ANY BANK OR NONBANK SUBSIDIARY OF NORWEST AND ARE NOT INSURED BY THE FEDERAL
DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENTAL AGENCY.

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

        All information concerning Norwest contained in this Proxy
Statement-Prospectus has been provided by Norwest, and all information
concerning FNB contained in this Proxy Statement-Prospectus has been provided by
FNB.

        This Proxy Statement-Prospectus is dated as of May 9, 1997 and, together
with the accompanying form of proxy, is first being mailed to shareholders of
FNB on or about May 9, 1997.

PARTIES TO THE MERGER

        NORWEST. Norwest Corporation ("Norwest") is a diversified financial
services company organized under the laws of Delaware in 1929 and registered
under the Bank Holding Company Act of 1956, as amended (the "Bank Holding
Company Act"). Through its subsidiaries and affiliates, Norwest provides retail,
commercial and corporate banking services, as well as a variety of other
financial services, including mortgage banking, consumer finance, equipment
leasing, agricultural finance, commercial finance, securities brokerage and
investment banking, insurance agency services, computer and data processing
services, trust services, mortgage-backed securities servicing, and venture
capital investment.

        At December 31, 1996, Norwest had consolidated total assets of $80.2
billion, total deposits of $50.1 billion and total stockholders' equity of $6.1
billion. Based on total assets at December 31, 1996, Norwest was the 12th
largest commercial banking organization in the United States.

        Norwest's principal executive offices are located at Norwest Center,
Sixth and Marquette, Minneapolis, Minnesota 55479, and its telephone number is
(612) 667-1234. As used in this Proxy Statement-Prospectus, the term "Norwest"
means Norwest and its consolidated subsidiaries.

        Additional  information  concerning  Norwest is included in  Norwest's
documents incorporated herein by reference. See "INCORPORATION OF CERTAIN 
DOCUMENTS BY REFERENCE."

        FNB. FNB is a one-bank holding company organized under the laws of New
Mexico in 1986 and registered under the Bank Holding Company Act. The principal
asset of FNB is the common stock of its subsidiary, The First National Bank of
Tucumcari (the "Bank"). As of December 31, 1996, FNB had consolidated total
assets of approximately $92.2 million and total shareholders' equity of
approximately $9.0 million. FNB had net income of $635,096 for the year ended
December 31, 1996. FNB's principal executive offices are located at 302 South
First Street, Tucumcari, New Mexico 88401, and its telephone number at that
address is (505) 461-3602. As used in this Proxy Statement-Prospectus, unless
otherwise indicated or the context requires otherwise, the term "FNB" means FNB
and the Bank.

        The Bank is a national banking association chartered in 1901 that has
banking offices in Tucumcari, Santa Rosa and Las Vegas, New Mexico. The Bank is
a full service, independent community bank that provides a full range of
commercial banking services, including traditional deposit services and

SPECIAL MEETING AND VOTE REQUIRED

        SPECIAL MEETING. The Special Meeting will be held on June 11, 1997 at
302 South First Street, Tucumcari, New Mexico, at 10:00 a.m., local time, for
the purpose of voting on a proposal to approve the Reorganization Agreement.
Only holders of record of FNB Common Stock at the close of business on May ___,
1997 (the "Record Date") will be entitled to receive notice of and to vote at
the Special Meeting. At the Record Date, there were 29,953 shares of FNB Common
Stock outstanding and entitled to vote at the Special Meeting. For additional
information relating to the Special Meeting, see "MEETING INFORMATION."

        VOTE REQUIRED. Approval of the Reorganization Agreement requires the
affirmative vote of the holders of a majority of the outstanding shares of FNB
Common Stock. Holders of FNB Common Stock are entitled to one vote per share
owned of record on the Record Date. If a majority of the votes eligible to be
cast by the holders of FNB Common Stock do not vote in favor of approval of the
Reorganization Agreement, FNB will remain a separate entity. As of the Record
Date, directors and executive officers of FNB and their affiliates owned
beneficially or controlled the voting of approximately 22,787 shares of FNB
Common Stock, representing approximately 76.1% of the shares of FNB Common Stock
outstanding on that date. Accordingly, these persons have the ability to approve
the Merger without the concurrence of any other shareholder. FNB's directors and
executive officers have informed FNB that they presently intend to vote all of
their shares in favor of approval of the Reorganization Agreement. See "MEETING
INFORMATION--Record Date; Voting Rights; Vote Required."

THE MERGER

        EFFECT OF THE MERGER. If the Reorganization Agreement is approved and
the Merger becomes effective, a wholly-owned subsidiary of Norwest will merge
with FNB, with FNB being the surviving corporation in the Merger and becoming a
wholly-owned subsidiary of Norwest. In the Merger, each share of FNB Common
Stock outstanding immediately prior to the Merger (other than shares as to which
statutory dissenters' rights have been validly exercised and not forfeited) will
be automatically converted into and represent the right to receive shares of
Norwest Common Stock and cash in lieu of fractional shares thereof. The number
of shares of Norwest Common Stock you will be entitled to receive will be
determined by multiplying the exchange ratio by the number of shares of FNB
Common Stock owned by you.

        EXCHANGE RATIO. The exchange ratio will be determined in accordance with
the formula set forth in paragraph 1(a) of the Reorganization Agreement. Under
the formula, the exchange ratio will equal the "Adjusted Norwest Shares" divided
by the number of shares of FNB Common Stock outstanding immediately prior to the
Effective Time of the Merger. The Adjusted Norwest Shares will be based on the
"Norwest Measurement Price," or the average of the closing prices of a share of
Norwest Common Stock, as reported on the NYSE during the 20 trading day period
ending on the last trading day before the Special Meeting. There are currently
29,953 shares of FNB Common Stock outstanding. Under the Reorganization
Agreement, the number of shares of FNB Common Stock that will be outstanding
immediately prior to the Merger may not be increased or decreased without the
consent of Norwest. As a result, in applying the formula to determine the range
of possible exchange ratios, you may assume that there will be 29,953 shares of
FNB Common Stock outstanding immediately prior to the Merger.

        The Adjusted Norwest Shares number (and thus the exchange ratio) will be
determined as follows:

    (1) If the Norwest Measurement Price is equal to or greater than $40.25,
        then the Adjusted Norwest Shares will be 304,472. In this case, the
        exchange ratio would equal 304,472 divided by 29,953, or 10.165.

                                       7
<PAGE>
 
    (2) If the Norwest Measurement Price is equal to or less than $36.25, then
        the Adjusted Norwest Shares will be 338,069. In this case, the exchange
        ratio would equal 338,069 divided by 29,953, or 11.287.

    (3) If the Norwest Measurement Price is less than $40.25 and more than
        $36.25, then the Adjusted Norwest Shares will be the number obtained by
        dividing $12,255,000 by the Norwest Measurement Price. Thus, for
        example, if the Norwest Measurement Price is $38, the Adjusted Norwest
        Shares would be $12,255,000 divided by $38, or 322,500. In this example,
        the exchange ratio would equal 322,500 divided by 29,953, or 10.767.

See "THE MERGER--Merger Consideration" for additional information on the
exchange ratio formula..

    REASONS FOR THE MERGER AND RECOMMENDATION OF THE FNB BOARD. At a meeting of
FNB's board of directors (the "FNB Board") held on January 17, 1997, after
considering the terms and conditions of the Reorganization Agreement, the FNB
Board approved the Reorganization Agreement. The FNB Board believes that the
Merger is advisable and in the best interests of FNB and its shareholders and
recommends that shareholders of FNB approve the Reorganization Agreement. In
reaching its determination to enter into the Reorganization Agreement, the FNB
Board considered a number of factors, including but not limited to the
following: the current and prospective economic environment and competitive
constraints facing independent community banks such as the Bank; the FNB Board's
view of reasonably available alternatives for the shareholders; the increased
liquidity and diversification of risk that the Merger would provide to FNB's
shareholders; and the FNB Board's view that the consideration to be received by
FNB's shareholders pursuant to the Reorganization Agreement was the highest
price reasonably obtainable. For a discussion of the circumstances surrounding
the Merger and the factors considered by the FNB Board in making its
recommendation, see "THE MERGER--Background of and Reasons for the Merger."

        THE BOARD OF DIRECTORS OF FNB UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS
VOTE IN FAVOR OF APPROVAL OF THE REORGANIZATION AGREEMENT.

        CONDITIONS TO THE MERGER; TERMINATION OF THE REORGANIZATION AGREEMENT.
The obligations of Norwest and FNB to effect the Merger are subject to the
satisfaction or, if permissible under the Reorganization Agreement, waiver of a
number of conditions, in addition to approval of the Reorganization Agreement by
FNB's shareholders. The Reorganization Agreement is subject to termination by
one or more parties at any time prior to the Effective Time of the Merger upon
the occurrence of certain specified events. See "THE MERGER--Conditions to the
Merger" and "--Termination of Reorganization Agreement."

        REGULATORY APPROVALS. The Merger is subject to the prior approval of the
Board of Governors of the Federal Reserve System (the "Federal Reserve Board")
and the Director of the Financial Institutions Division of the Regulation and
Licensing Department of the state of New Mexico. Norwest has filed applications
with these authorities requesting approval of the Merger; however, there can be
no assurance that the necessary regulatory approval will be obtained or as to
the timing or conditions of such approval. See "THE MERGER--Regulatory
Approvals."

        EFFECTIVE TIME AND CLOSING OF THE MERGER. If the Reorganization
Agreement is approved at the Special Meeting and all other conditions to the
Merger have been satisfied or waived, the parties expect the Merger to become
effective (the "Effective Time of the Merger") at 11:59 p.m. on the date the
required documents relating to the Merger are filed with and accepted by the New
Mexico State Corporation Commission in accordance with the relevant provisions
of the New Mexico Business Corporation Act ("NMBCA"). The parties expect to file
the required documents as soon as practicable following approval of the
Reorganization 

                                       8
<PAGE>
 
Agreement at the Special Meeting. See "THE MERGER--Conditions to the Merger" and
"--Regulatory Approvals."

        COMPETING TRANSACTIONS. Subject to certain exceptions, FNB and the Bank,
and their respective directors, officers, representatives and agents, are
prohibited under the Reorganization Agreement from directly or indirectly
soliciting, authorizing the solicitation of or entering into any discussions
with any party other than Norwest concerning certain transactions involving the
acquisition of FNB's or the Bank's capital stock or assets. See "THE
MERGER--Competing Transactions."

        INTERESTS OF CERTAIN PERSONS IN THE MERGER. In the Merger, FNB's
directors and executive officers will receive the same consideration for their
shares of FNB Common Stock as the other shareholders of FNB will receive for
their shares of FNB Common Stock. Certain members of the FNB Board and
management, however, may be deemed to have interests in the Merger that are in
addition to and separate from the interests of FNB's shareholders generally.
These interests include, among others: the Employment and Non-Competition
Agreements executed by H. Barton Jones and Craig L. Cosner; the termination of
certain Salary Continuation Agreements between the Bank and nine of its officers
in consideration of the payment of an aggregate of approximately $373,000 to
such officers; the offer to any officer, director or employee of FNB or the Bank
to purchase from FNB or the Bank any life insurance policy with respect to such
individual, which has FNB as the beneficiary thereof, at a price equal to the
cash value thereof; and provisions in the Reorganization Agreement relating to
the continuation of certain director and officer indemnification rights and the
maintenance of certain directors' and officers' liability insurance policies.
See "INFORMATION ABOUT FNB AND THE BANK--Management of FNB--Interests of
Management and Others in Certain Transactions."

        DIRECTORS AND OFFICERS OF FNB AFTER THE MERGER. Following the Effective
Time of the Merger, Norwest will be the sole shareholder of FNB and, for that
reason, will be in a position to elect or appoint all of the directors and
officers of FNB.

        DISSENTERS' RIGHTS. Under New Mexico law, holders of FNB Common Stock
will have the right to dissent from the Merger and, subject to certain
conditions, receive a cash payment equal to the fair value of their shares.
Failure to comply strictly with the statutory procedures in the exercise of
dissenters' rights will nullify such rights. For more information concerning
dissenters' rights and the procedures to be followed to exercise such rights,
see "THE MERGER--Dissenters' Rights" and Appendix C.

        CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES. It is intended that the
Merger will be treated as a reorganization within the meaning of Section 368(a)
of the Internal Revenue Code of 1986, as amended (the "Code"), and that as a
result (a) no gain or loss will be recognized by the holders of FNB Common Stock
upon receipt of Norwest Common Stock in exchange therefor pursuant to the
Merger, except for cash received in lieu of fractional shares; (b) the aggregate
adjusted tax basis of the Norwest Common Stock received by the holders of FNB
Common Stock will be the same as the aggregate adjusted tax basis of the FNB
Common Stock exchanged therefor reduced by the amount allocable to fractional
share interests for which cash is received; and (c) the holding period of the
shares of Norwest Common Stock received by the holders of FNB Common Stock will
include the holding period of the FNB Common Stock, provided the shares of FNB
Common Stock were held as a capital asset as of the Effective Time of the
Merger. See "THE MERGER-- Certain U.S. Federal Income Tax Consequences."
Consummation of the Merger is conditioned upon the receipt by FNB of an opinion
of Bracewell & Patterson, L.L.P., Houston, Texas, counsel for FNB, substantially
to such effect.

        THE U.S. FEDERAL INCOME TAX CONSIDERATIONS OF THE MERGER MAY BE
DIFFERENT FOR PARTICULAR TYPES OF FNB SHAREHOLDERS OR IN LIGHT OF EACH FNB
SHAREHOLDER'S PERSONAL INVESTMENT CIRCUMSTANCES. FOR THAT REASON, FNB
SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE U.S.
FEDERAL INCOME TAX CONSEQUENCES THAT MAY BE RELEVANT TO THEM IN CONNECTION WITH
THE MERGER, AS WELL AS THE APPLICATION TO THEM OF ANY STATE, LOCAL, FOREIGN, OR
OTHER TAX LAWS AND THE POSSIBLE EFFECT OF CHANGES IN SUCH LAWS.

MARKET INFORMATION

        On January 16, 1997 (the last business day preceding public announcement
of the Reorganization Agreement) and on May , 1997 (the last practicable date
prior to the mailing of this Proxy Statement-Prospectus), the closing prices per
share of Norwest Common Stock (as reported on the NYSE composite tape) were
$46.25 and $_____, respectively. The market price for Norwest Common stock will
fluctuate between the date of this Proxy Statement-Prospectus and the Effective
Time of the Merger, which may be a period of several weeks or more. As a result,
the market value per share of the Norwest Common Stock that shareholders of FNB
ultimately receive in the Merger could be more or less than its market value on
the date of this Proxy Statement-Prospectus. No assurance may be given
concerning the market price of the Norwest Common Stock before or after the
Effective Time of the Merger.

        There is no public  market for FNB Common  Stock.  See  "INFORMATION  
ABOUT FNB AND THE BANK--Market Information and Dividends."

COMPARISON OF RIGHTS OF HOLDERS OF FNB COMMON STOCK AND NORWEST COMMON STOCK

        As of the date of this Proxy Statement-Prospectus, the rights of FNB's
shareholders are governed by the NMBCA and the FNB Articles and FNB Bylaws. At
the Effective Time of the Merger, FNB's shareholders will become stockholders of
Norwest. For that reason, their rights will thereafter be governed by the
Delaware General Corporation Law (the "DGCL") and the Norwest Certificate and
Norwest Bylaws. See "COMPARISON OF RIGHTS OF HOLDERS OF FNB COMMON STOCK AND
NORWEST COMMON STOCK" for additional information and for definitions of certain
capitalized terms.

COMPARATIVE PER COMMON SHARE DATA

        The following table presents selected comparative per common share data
for Norwest Common Stock on a historical and pro forma combined basis and for
FNB Common Stock on a historical and pro forma equivalent basis giving effect to
the Merger using the purchase method of accounting. (For a description of the
purchase method of accounting and the related effects on the historical
financial statements of Norwest, see "THE MERGER--Accounting Treatment.") The
historical data for Norwest for the year ended December 31, 1996 included in the
table are derived from the audited consolidated financial statements of Norwest
(including the related notes thereto) incorporated by reference into this Proxy
Statement-Prospectus. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE." The
historical data for FNB for the year ended December 31, 1996 included in the
table are derived from FNB's audited consolidated financial statements included
in the Proxy Statement-Prospectus.

        The data in the table are based on the assumption that 304,472 shares of
Norwest Common Stock will be issued in the Merger. This number is based on an
assumed Norwest Measurement Price of $40.25 or more and the resulting exchange
ratio of 10.165 shares of Norwest Common Stock for each share of FNB Common
Stock. The exchange ratio of 10.165 shares of Norwest Common Stock for each
share of FNB Common Stock is referred to in the footnotes to the table as the
"assumed exchange ratio." The actual Norwest Measurement Price (and thus the
actual exchange ratio) will not be determined until the end 

                                       10
<PAGE>
 
of a 20-trading day measurement period ending on the last trading day before the
Special Meeting. See "THE MERGER--Merger Consideration" for the definition of
the term Norwest Measurement Price.

        The comparative per common share data set forth in the following table
are not necessarily indicative of the results of the future operations of the
combined entity or the actual results that would have occurred had the Merger
become effective prior to the periods indicated.

(1)     The pro forma combined book value per share of Norwest Common Stock
        represents the historical total combined common stockholders' equity for
        Norwest and FNB divided by total pro forma common shares of the combined
        entities. The pro forma equivalent book value per share of Norwest
        Common Stock represents the pro forma combined book value per share
        multiplied by the assumed exchange ratio of 10.165.

(2)     Assumes no changes in cash dividends per share by Norwest. The pro forma
        equivalent dividends per share of FNB Common Stock represent cash
        dividends declared per share of Norwest Common Stock multiplied by the
        assumed exchange ratio of 10.165.

(3)     The pro forma combined net income per share of Norwest Common Stock
        (based on fully diluted net income and weighted average number of common
        and common equivalent shares) is based upon the combined historical net
        income for Norwest and FNB divided by the average pro forma common and
        common equivalent shares of the combined entities. The pro forma
        equivalent net income per share of FNB Common Stock represents the pro
        forma combined net income per share multiplied by the assumed exchange
        ratio of 10.165.

                                  MEETING INFORMATION

GENERAL

        This Proxy Statement-Prospectus is being furnished to holders of FNB
Common Stock in connection with the solicitation of proxies by the FNB Board for
use at the Special Meeting and at any adjournments or postponements thereof. The
Special Meeting will be held on June 11, 1997 at 10:00 a.m., local time, at 302
South First Street, Tucumcari, New Mexico.

        At the Special Meeting, shareholders of FNB will consider and vote upon
a proposal to approve the Reorganization Agreement. The FNB Board is not aware
as of the date of this Proxy Statement-Prospectus of any business to be acted
upon at the Special Meeting other than the proposal to approve the
Reorganization Agreement. If other matters are properly brought before the
Special Meeting or any adjournments or postponements thereof, the persons
appointed as proxies will have discretion to vote or act on such matters
according to their best judgment.

RECORD DATE; VOTING RIGHTS; VOTE REQUIRED

        The FNB Board has fixed the close of business on May ___, 1997 as the
record date for the determination of shareholders of FNB entitled to receive
notice of and to vote at the Special Meeting (the "Record Date"). On the Record
Date there were 29,953 shares of FNB Common Stock outstanding and entitled to
vote. Holders of FNB Common Stock are entitled to one vote per share held of
record on the Record Date. The presence in person or by proxy at the Special
Meeting of the holders of a majority of the shares of FNB Common Stock
outstanding on the Record Date will constitute a quorum for the transaction of
business at the Special Meeting.

        Under the NMBCA and the FNB Articles and FNB Bylaws, approval of the
Reorganization Agreement will require the affirmative vote of the holders of a
majority of the outstanding shares of FNB Common Stock. Directors and executive
officers of FNB and their affiliates beneficially owned as of the Record Date an
aggregate of approximately 22,787 shares, or approximately 76.1%, of the
outstanding shares of FNB Common Stock. Accordingly, these persons may approve
the merger without the concurrence of any other shareholder. FNB has been
informed that its directors and executive officers and their affiliates
presently intend to vote their shares of FNB Common Stock in favor of approval
of the Reorganization Agreement.

        A failure to vote, either by not returning the enclosed proxy or by
checking the "Abstain" box thereon, will have the same effect as a vote against
approval of the Reorganization Agreement. See "--Voting and Revocation of
Proxies."

        If a majority of the votes eligible to be cast by the holders of FNB
Common Stock do not vote in favor of approval of the Reorganization Agreement,
FNB will remain a separate entity.

                                       16

VOTING AND REVOCATION OF PROXIES

        Shares of FNB Common Stock represented by a proxy properly signed and
received at or prior to the Special Meeting, unless subsequently revoked, will
be voted at the Special Meeting in accordance with the instructions thereon. If
a proxy is signed and returned without indicating any voting instructions,
shares of FNB Common Stock represented by such proxy will be voted FOR approval
of the Reorganization 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 FNB 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 by 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 the
name of a nominee 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 will not be counted as voting in favor of such proposal. The
proposal to approve the Reorganization Agreement must be approved by the holders
of a majority of the shares of FNB Common Stock outstanding on the Record Date.
Because the proposal to approve the Reorganization Agreement 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 voting against the proposal.

SOLICITATION OF PROXIES

        In addition to solicitation by mail, directors, officers and employees
of FNB and the Bank may solicit proxies from the shareholders of FNB, either
personally or by telephone 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. FNB
will bear its own expenses in connection with any solicitation of proxies for
the Special Meeting. See "THE MERGER--Expenses."

THE MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING ARE OF GREAT IMPORTANCE TO
THE SHAREHOLDERS OF FNB. SHAREHOLDERS ARE URGED TO READ AND CAREFULLY CONSIDER
THE INFORMATION PRESENTED IN THIS PROXY STATEMENT-PROSPECTUS AND TO COMPLETE,
DATE AND SIGN THE ACCOMPANYING PROXY AND RETURN IT PROMPTLY TO FNB IN THE
ENCLOSED POSTAGE-PREPAID ENVELOPE.

                                      THE MERGER

        This section of the Proxy Statement-Prospectus describes certain aspects
of the Merger. The following description does not purport to be complete and is
qualified in its entirety by reference to the Reorganization Agreement, a copy
of which is attached as Appendix A to this Proxy Statement-Prospectus and
incorporated herein by reference. Shareholders are urged to read the
Reorganization Agreement in its entirety.

        Parenthetical references are to sections of the Reorganization
Agreement. FNB and the Bank are referred to in the Reorganization Agreement as
"FNBI" and "FNBI Subsidiary," respectively.

GENERAL

        At the Effective Time of the Merger, a wholly-owned subsidiary of
Norwest will be merged with FNB, with FNB being the surviving corporation in the
Merger and becoming a wholly-owned subsidiary of Norwest. Except with respect to
fractional shares and shares as to which dissenters' rights have been exercised,
if the Reorganization Agreement is approved and the Merger becomes effective,
each share of FNB Common Stock outstanding immediately prior to the Effective
Time of the Merger will be automatically converted into and represent the right
to receive shares of Norwest Common Stock. See "--Merger Consideration" below.
Following the Effective Time of the Merger, Norwest will be the sole shareholder
of FNB. Shares of Norwest Common Stock issued and outstanding immediately before
the Effective Time of the Merger will remain issued and outstanding immediately
after the Effective Time of the Merger.

MERGER CONSIDERATION

        SHARES OF NORWEST COMMON STOCK. Except with respect to fractional shares
as described below and shares as to which dissenters' rights have been
exercised, if the Reorganization Agreement is approved and the Merger becomes
effective, you will be entitled to receive shares of Norwest Common Stock in
exchange for shares of FNB Common Stock owned by you. The number of shares of
Norwest Common Stock you will be entitled to receive will be determined by
multiplying the exchange ratio by the number of shares of FNB Common Stock owned
by you immediately prior to the Merger.

        The exchange ratio will be determined in accordance with the formula set
forth in paragraph 1(a) of the Reorganization Agreement. The formula provides
that the exchange ratio will equal the "Adjusted Norwest Shares" divided by the
number of shares of FNB Common Stock outstanding immediately prior to the
Effective Time of the Merger. The Adjusted Norwest Shares number is based on the
"Norwest Measurement Price," which is defined as the average of the closing
prices of a share of Norwest Common Stock, as reported on the NYSE during the 20
trading day period ending on the last trading day before the Special Meeting.
Under the terms of the Reorganization Agreement, the maximum number of shares of
FNB Common Stock that may be outstanding immediately prior to the Effective Time
of the Merger is 29,953 shares. (paragraph 2(c)) In addition, FNB is prohibited
under the Reorganization Agreement from redeeming or purchasing shares of FNB
Common Stock without the consent of Norwest. (paragraph 4(b)) As a result, for
purposes of applying the formula, you may assume that there will be 29,953
shares of FNB Common Stock outstanding immediately prior to the Effective Time
of the Merger.

                                       18
<PAGE>
 
        The Adjusted Norwest Shares number (and thus the exchange ratio) will be
determined as follows:

    (1) If the Norwest Measurement Price is equal to or greater than $40.25,
        then the Adjusted Norwest Shares will be 304,472. In this case, the
        exchange ratio would equal 304,472 divided by 29,953, or 10.165.

    (2) If the Norwest Measurement Price is equal to or less than $36.25, then
        the Adjusted Norwest Shares will be 338,069. In this case, the exchange
        ratio would equal 338,069 divided by 29,953, or 11.287.

    (3) If the Norwest Measurement Price is less than $40.25 and more than
        $36.25, then the Adjusted Norwest Shares will be the number obtained by
        dividing $12,255,000 by the Norwest Measurement Price. Thus, for
        example, if the Norwest Measurement Price is $38, the Adjusted Norwest
        Shares would be $12,255,000 divided by 38, or 322,500. In this example,
        the exchange ratio would equal 322,500 divided by 29,953, or 10.767.

The closing price of a share of Norwest Common Stock on the effective date of
the Merger may be higher or lower than the Norwest Measurement Price.

        CASH IN LIEU OF REMAINING FRACTIONAL SHARES. In the event the aggregate
number of shares of Norwest Common Stock you are entitled to receive in the
Merger does not equal a whole number, you will receive cash in lieu of the
fractional share. The cash payment will be equal to the product of the
fractional part of the share of Norwest Common Stock multiplied by the average
of the closing prices of a share of Norwest Common Stock as reported by the
consolidated tape of the NYSE for each of the five trading days immediately
preceding the Effective Time of the Merger. (paragraph 1(c))

BACKGROUND OF AND REASONS FOR THE MERGER

        Since the early 1990s, FNB management has monitored developments in bank
acquisitions in New Mexico, along with developments in the banking industry
generally. During this time, members of the FNB Board became concerned that
industry trends toward competition, consolidation and the increased use of
technology could combine to erode FNB's customer base. In 1994, a representative
of Norwest's then existing operation in New Mexico contacted management of FNB,
stating that Norwest had an interest in establishing a presence in the markets
served by the Bank and inquiring whether FNB had any interest in being acquired
by Norwest. While FNB was not interested in pursuing discussions at that time,
this inquiry confirmed that competition from larger financial institutions
utilizing increasingly sophisticated technology would be a factor in the future
in FNB's markets.

        Subsequent to 1994, FNB continued to monitor bank acquisition activity
in New Mexico, identifying and investigating in an informal way the institutions
that served New Mexico. At the same time, FNB continued to observe anecdotal
evidence of the increasing competition in the banking industry, and the need for
significant investments in technology to provide the products and services
necessary to obtain and retain customers. In January 1996, the Chairman met with
FNB's traditional legal and accounting advisors to discuss FNB's future. As a
result of these discussions, the FNB Board determined that it was time to
investigate whether a merger with a larger institution would be in the best
interests of its shareholders. Based on its informal investigations, senior
management of FNB had formed the belief that a stock-for-stock transaction with
Norwest afforded the best opportunity for 

                                       19
<PAGE>
 
the FNB shareholders. If a satisfactory arrangement could be negotiated with
Norwest, FNB believed that it would be in the interests of its shareholders to
manage the acquisition process affirmatively, rather than to wait for a second
approach from Norwest or an offer from another acquiror. Accordingly, in
February 1996 the Chairman contacted the Norwest representative who had
previously contacted FNB to ascertain whether Norwest would still be interested
in discussing the acquisition of FNB. The Norwest representative responded
affirmatively, and undertook to begin the process.

        The acquisition process proceeded deliberately, and while it was ongoing
FNB considered whether approaching other potential acquirors would reduce the
time necessary to complete a transaction and result in a comparable value to
shareholders. After considering the other institutions active in New Mexico,
including transactions completed by these parties and the price and liquidity of
their common equity securities, FNB concluded that a transaction with Norwest,
if it could be completed, would be preferable to a transaction with other
potential acquirors. Accordingly, FNB determined to continue its negotiations
with Norwest.

        In August 1996, a Norwest representative indicated to FNB a willingness
to discuss a cash merger transaction valued at $12,500,000. After due
consideration, FNB indicated its disappointment with the both the form and
amount of consideration, as well as the taxable nature of the transaction.
Following further negotiations, Norwest's representative tendered a proposal in
September 1996 to acquire FNB for 340,000 shares of Norwest Common Stock. As a
result, FNB and Norwest eventually signed a nonbinding letter of intent
providing for the acquisition of FNB for shares of Norwest Common Stock
containing the price ranges (or "collars") eventually included in the
Reorganization Agreement. During November 1996 Norwest completed its due
diligence examination of FNB and the Bank and thereafter submitted several draft
agreements for review by FNB and its legal and accounting advisors, which
included certain modifications based on the results of Norwest's review. The
negotiation process concluded on January 17, 1997 with the execution of the
Reorganization Agreement.

        In reaching its decision to approve the terms of the Reorganization
Agreement, the FNB Board considered a number of factors, including, without
limitation, the following:

        1. The familiarity of the FNB Board with FNB's business, operations,
    financial condition, earnings and prospects, and its investigation (directly
    and through its advisors) of similar matters concerning Norwest.

        2. The current and prospective economic environment and competitive
    constraints facing FNB, including specifically the superior products and
    services which larger competitors could offer to customers and the need for
    substantial investments by FNB in technology to compete with such
    competitors.

        3. The limited alternatives available to FNB and the relation of the
    price to be received by the FNB shareholders in the Merger to the FNB
    Board's view of the value of these limited alternatives, as well as the
    timing and likelihood of actually receiving, and the risks associated with
    pursuing, such alternatives.

        4. The expectation that the receipt of the Norwest Common Stock
    generally will be a tax-free transaction to the FNB shareholders, allowing
    them to defer the recognition of this gain.

        5. The FNB Board's evaluation of the risks to the consummation of the
    Merger, including the risks associated with obtaining all necessary
    regulatory approvals without 

                                       20
<PAGE>
 
    the imposition of terms or conditions which would fail to satisfy the
    conditions to the consummation of the Merger.
    
        6.  The increased  liquidity  that the Norwest Common Stock would 
    provide to current FNB shareholders.
    
        In its deliberations, the FNB Board did not assign any specific weights
to these or any other factors.

        Based on the foregoing and other factors, the FNB Board concluded that
the Merger is in the best interests of FNB and its shareholders. ACCORDINGLY,
THE BOARD OF DIRECTORS OF FNB UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS VOTE
IN FAVOR OF THE APPROVAL OF THE REORGANIZATION AGREEMENT.

DISSENTERS' RIGHTS

        Shareholders of FNB are entitled to exercise dissenters' rights under
Sections 53-15-3 and 53-15-4 of the NMBCA. Shareholders electing to demand the
appraisal of their shares may not vote in favor of the Merger and must deliver a
written objection to the Merger to FNB at its principal executive offices either
before the date of the Special Meeting or before the taking of the vote on the
Merger at the Special Meeting. By properly executing a proxy card with no voting
instructions indicated thereon, a shareholder will vote in favor of the approval
and adoption of the Reorganization Agreement and, accordingly, will not be
entitled to exercise dissenters' rights in connection with the Merger. If the
Merger is approved, a shareholder who did not vote in favor of the Merger may,
within ten days after the date on which the vote on the Merger is taken, make
written demand on FNB, as the surviving corporation, for payment of the fair
value of the shareholder's shares in cash. Such demand will be sufficient if it
reasonably informs FNB of the identity of the shareholder and that the
shareholder intends thereby to demand the appraisal of the shareholder's shares.
Because a proxy or vote against the Merger will not constitute such a demand, a
separate written demand is required. Failure to comply with these procedures,
including without limitation the failure to demand payment within ten days
following approval of the Merger Agreement by the FNB shareholders, will cause
the shareholder to lose his dissenters' rights with respect to such shares.

        Within ten days after the Effective Time of the Merger, FNB will give
written notice to each shareholder who has made a demand for appraisal of the
effectiveness of the Merger and will make a written offer to each such
shareholder to pay for such shares at a specified price deemed by FNB to be the
fair value of the shares. The notice and offer must be accompanied by FNB's
balance sheet as of the last available date (but no more than 12 months prior to
the making of the offer) and a profit and loss statement for the 12-month period
ended on the date of the balance sheet. If, within 30 days after the Effective
Time of the Merger, the shareholder and FNB reach an agreement as to the fair
value of the shareholder's shares, FNB will remit the fair value payment agreed
upon to the shareholder within 90 days after the Effective Time of the Merger
and upon surrender of the certificates representing such shares. If FNB and the
shareholder do not agree upon the fair value of the shareholder's shares within
such 30-day period, then, within 30 days after receipt of written demand from
any dissenting shareholder which is given within 60 days after consummation of
the Merger, FNB shall, or at FNB's election at any time within such 60-day
period FNB may, file a petition in any court of competent jurisdiction in the
county where FNB's registered office is located (the "Court"), asking that the
Court determine the fair value of the shares. If FNB fails to file such a
petition, any shareholder demanding appraisal rights may do so on FNB's behalf.
All shareholders asserting appraisal rights will 

                                       21
<PAGE>
 
be made parties to any court action filed to determine such fair value. No
demand for appraisal may be withdrawn without the consent of FNB. If a demand is
withdrawn with the consent of FNB, the shareholder's status will be restored and
he will participate in the Merger in accordance with its terms.

        At a hearing on a petition for appraisal, the Court may, in its
discretion, appoint one or more appraisers to receive evidence and to recommend
a decision on the question of fair value. The appraisers shall have such power
and authority as may be specified in the order of their appointment. The fair
value of the shares is to be determined exclusive of any element of value
arising from the accomplishment or expectation of the Merger, together with a
fair rate of interest, if any, to be paid upon the amount determined to be the
fair value. The fair value of the shares, as determined by the Court, together
with interest, if any, will be required to be paid by FNB to all dissenting
holders of FNB Common Stock who have complied with Section 53-15-4.

        The Court will assess the costs and expenses of such proceeding,
including reasonable compensation for and the expenses of the appraiser, but
excluding fees and expenses of counsel and experts, against FNB, except that the
Court may assess such costs and expenses as it deems appropriate against any or
all of the dissenting shareholders if it finds that their failure to accept
FNB's offer of payment was arbitrary, vexatious, or otherwise not in good faith.
The Court may award fees of counsel and experts in amounts the Court finds
reasonable against FNB if the determined fair value of the shares materially
exceeds the amount offered by FNB or if FNB fails to make a required offer.

        Upon receiving a demand for payment from a dissenting shareholder, FNB
is required to make an appropriate notation in its shareholder records. Within
20 days of demanding payment for such shareholder's shares, each holder of
shares represented by certificates demanding payment shall submit the
certificates to the corporation for notation thereon that such demand has been
made. The failure of a shareholder to do so shall, at the option of FNB,
terminate such shareholder's right to seek appraisal of the shares unless a
court of competent jurisdiction, for good and sufficient cause shown, otherwise
directs.

        From and after the Effective Time of the Merger, no shareholder who has
demanded appraisal rights will be entitled to vote such shareholder's shares of
FNB Common Stock for any purpose or to receive payment of dividends or other
distributions on such stock.

        Any demands, notices, or other documents required to be sent to FNB
should be sent to FNB at the address at the forepart of this Proxy
Statement-Prospectus.

        THE FOREGOING SUMMARY OF DISSENTERS' RIGHTS DOES NOT PURPORT TO BE A
COMPLETE STATEMENT OF THE PROCEDURE OUTLINED IN THE RELEVANT PROVISIONS OF THE
NMBCA, WHICH ARE REPRODUCED IN THEIR ENTIRETY AS APPENDIX C TO THIS PROXY
STATEMENT-PROSPECTUS. FURTHERMORE, BECAUSE OF THE COMPLEXITY OF THE PROCEDURES
DESCRIBED ABOVE, ANY SHAREHOLDER WISHING TO EXERCISE THE RIGHT TO AN APPRAISAL
MAY WISH TO CONSULT WITH COUNSEL.

SURRENDER OF CERTIFICATES

        Promptly following the Effective Time of the Merger, Norwest Bank
Minnesota, National Association, acting in the capacity of exchange agent for
Norwest (the "Exchange Agent"), will mail to each holder of record of shares of
FNB Common Stock a form of letter of transmittal, together with instructions for
the exchange of such holder's stock certificates for a certificate representing
Norwest Common Stock.

                                       22
<PAGE>
 
 SHAREHOLDERS  OF FNB 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 FNB
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, if
applicable, a check for the amount representing any remaining fractional share
(without interest). 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 is 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 taxes have been paid or are
not due.

        All Norwest Common Stock issued pursuant to the Merger will be deemed
issued as of the Effective Time of the Merger. No dividends in respect of the
Norwest Common Stock with a record date after the Effective Time of the Merger
will be paid to the former shareholders of FNB entitled to receive certificates
for shares of Norwest Common Stock until such shareholders surrender their
certificates representing shares of FNB 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 Merger
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 Merger, as the case may be, 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.

shall not have exceeded 29,953; (iv) Norwest shall have entered into written
employment agreements with H. Barton Jones and Craig L. Cosner containing terms
reasonably acceptable to the parties thereto; and (v) the absence of any
occurrence or circumstance which has had or might reasonably be expected to have
a material adverse effect on the financial condition, results of operation or
business of FNB 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). (paragraph 8)

        See paragraphs 6, 7 and 8 of the Reorganization Agreement for additional
conditions to the Merger becoming effective.

REGULATORY APPROVALS

        The Merger is subject to prior approval by the Federal Reserve Board
under the Bank Holding Company Act and by the Director of Financial Institutions
Division of the Regulation and Licensing Department of the state of New Mexico.
Norwest has filed applications with these authorities requesting approval of the
Merger; however, there can be no assurance that the necessary regulatory
approval will be obtained or as to the timing of or conditions placed on such
approval.

        The approval of any application merely implies satisfaction of
regulatory criteria for approval, which do not include review of the Merger 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 Merger.

        Norwest and FNB are not aware of any governmental approvals or
compliance with banking laws and regulations that are required for the Merger to
become effective other than those described above. The parties currently intend
to seek to obtain any other approval and to take any other action that may be
required to effect the Merger. There can be no assurance that any required
approval or action can be obtained or taken prior to the Special Meeting. The
receipt of all necessary regulatory approvals is a condition to effecting the
Merger. See "--Conditions to the Merger" and "--Termination of Reorganization
Agreement."

dividends on FNB Common Stock, in accordance with applicable law and regulation,
not to exceed $4.00 per share per semi-annual period, or a quarterly equivalent
thereto; provided, however that shareholders of FNB shall be entitled to a

their businesses or properties. (paragraph 5)

        See paragraphs 4 and 5 of the Reorganization Agreement for additional
restrictions on the conduct of business by FNB and Norwest pending the Merger.

COMPETING TRANSACTIONS

        FNB and the Bank, and their respective directors, officers,

makes an offer or inquiry to FNB or the Bank concerning any of the foregoing,
FNB or the Bank, as applicable, is required to promptly disclose such offer or
inquiry (including the terms thereof) to Norwest. (paragraph 4(h))

requested by Norwest, amend, effective as of the Effective Time of the Merger,
certain employee benefit plans of FNB and the Bank; (ii) establish, immediately
prior to the Effective Time of the Merger, such additional accruals and reserves
as may be necessary to conform FNB's accounting and credit loss reserve

Securities Act. (paragraph 4)

        NORWEST. Norwest has agreed under the Reorganization Agreement to (i)
take certain action to maintain FNB's directors' and officers' liability

concerning the directors' and officers' liability insurance policies, see
"INFORMATION ABOUT FNB AND THE BANK--Management of FNB--Interests of Management
and Others in Certain Transactions."

        For information concerning additional agreements and covenants of FNB
and Norwest, see paragraphs 4 and 5 of the Reorganization Agreement.

TERMINATION OF REORGANIZATION AGREEMENT

        Subject to the satisfaction of certain notice requirements, either
Norwest or FNB may terminate the Reorganization Agreement at any time prior to
the Effective Time of the Merger, whether before or after approval of the
Reorganization Agreement by FNB's shareholders, pursuant to the mutual written
consent of each party or upon the occurrence or existence of either of the
following events or conditions: (i) the Merger has not become effective by
September 30, 1997, unless such failure of the Merger to become effective 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 Reorganization Agreement; or (ii) any court or governmental authority
of competent jurisdiction shall have issued a final order restraining, enjoining
or otherwise prohibiting the transactions contemplated by the Reorganization
Agreement. (paragraph 10)

AMENDMENT OF REORGANIZATION AGREEMENT

        The Reorganization Agreement may be amended by the parties thereto,
pursuant to action taken by their respective boards of directors or pursuant to
authority delegated by their respective boards of directors, at any time before
or after approval of the Reorganization Agreement by FNB's shareholders,
provided that, after the Reorganization Agreement is approved by FNB's
shareholders, no amendment may be made to the 

                                       26
<PAGE>
 
Reorganization Agreement that changes in a manner adverse to FNB's shareholders
the consideration to be received by FNB's shareholders in the Merger. (paragraph
10)

WAIVER OF PERFORMANCE OF OBLIGATIONS

        Either party to the Reorganization Agreement may, by a signed writing,
give any consent, take any action with respect to the termination of the
Reorganization Agreement or otherwise, or waive any inaccuracies in the
representations and warranties of the other party or compliance by the other
party with any of the covenants or conditions contained in the Reorganization
Agreement. (paragraph 10)

EFFECT ON EMPLOYEE BENEFIT PLANS

        The Reorganization Agreement provides that, subject to any eligibility
requirements applicable to such plans, employees of FNB shall be entitled to
participate in those Norwest employee benefit and welfare plans specified in the
Reorganization Agreement. The eligible employees of FNB shall enter each of such
plans no later than the first day of the calendar quarter which begins at least
32 days after the Effective Time of the Merger. FNB's employees will generally
continue to participate in welfare and retirement plans maintained by FNB until
entering Norwest's plans. FNB employees will receive credit for past service
with FNB for the purpose of satisfying any eligibility and vesting periods under
certain, but not all, of Norwest's benefit plans. FNB employees will not be
subject to any pre-existing condition exclusions when entering a Norwest welfare
benefit plan, except for the Norwest Long Term Care Plan. (paragraph 9)

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

        This description of certain U.S. federal income tax considerations with
respect to the Merger is included solely for the information of FNB
shareholders. No information is provided with respect to the consequences of any
applicable state, local, or foreign tax laws. Applicability of the alternative
minimum tax and other tax consequences of the Merger to an FNB shareholder will
depend upon the individual situation of such shareholder. Furthermore, special
tax considerations may apply to FNB shareholders who are insurance companies,
securities dealers, financial institutions, and foreign persons. Therefore, EACH
FNB SHAREHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX ADVISOR CONCERNING THE
SPECIFIC TAX CONSEQUENCES OF THE MERGER TO SUCH SHAREHOLDER.

        It is intended that the Merger will be treated as a reorganization
within the meaning of Section 368(a) of the Code and that, accordingly, for
federal income tax purposes: (i) no gain or loss will be recognized by Norwest
or FNB as a result of the Merger; (ii) no gain or loss will be recognized by
holders of FNB Common Stock upon the receipt of Norwest Common Stock in exchange
for FNB Common Stock pursuant to the Merger, except as discussed below with
respect to cash received in lieu of a fractional share interest in common stock;
(iii) the aggregate adjusted tax basis of the shares of Norwest Common Stock
received by the holders of FNB Common Stock surrendered in exchange therefor
will be equal to the tax basis of such shareholder's shares of FNB Common Stock
(reduced by the amount allocable to fractional share interests for which cash is
received); and (iv) the holding period of the shares of Norwest Common Stock
received by the holders of FNB Common Stock will include the holding period of
the FNB Common Stock, provided the shares of FNB Common Stock were held as a
capital asset as of the Effective Time of the Merger.

                                       27
<PAGE>
 
        FNB does not intend to apply for a ruling from the IRS with respect to
the federal income tax consequences of the Merger. Instead, it intends to rely
on the opinion of its legal counsel. Consummation of the Merger is conditioned
upon receipt by FNB of the opinion of Bracewell & Patterson, L.L.P., Houston,
Texas, dated as of the closing date of the Merger, substantially to the effect
that, on the basis of facts, representations and assumptions set forth or
referred to in such opinion, the principal federal income tax consequences of
the Merger under current law will be as set forth in items (ii)-(iv) above. An
opinion of counsel is not binding upon the IRS or the courts. The tax opinion
will be based upon certain factual assumptions and upon certain representations
and assurances made by FNB. The tax opinion will not address the consequences of
the Merger on FNB shareholders under applicable state or local income tax laws.

        One of the requirements for tax-free reorganization treatment is that
shareholders of the acquired corporation acquire a substantial and continuing
interest in the acquiring corporation. The tax opinion received by FNB will be
based on the assumption that the shareholders of FNB have no plan or intention
at the time of the Merger to sell or otherwise dispose of an amount of Norwest
Common Stock to be received in the Merger that would reduce their aggregate
ownership of Norwest Common Stock to a number of shares having in the aggregate
a value at the time of the Merger of less than 50% of the total value of FNB
Common Stock outstanding immediately prior to the Merger. For purposes of such
determination, shares of FNB Common Stock that are exchanged for cash or other
property, or surrendered by FNB shareholders exercising dissenters' appraisal
rights, or exchanged for cash in lieu of the issuance of fractional shares of
Norwest Common Stock, will be treated as outstanding shares of FNB Common Stock
immediately prior to the Merger.

        Holders of FNB Common Stock who participate in the Merger and who
receive cash in lieu of a fractional share of Norwest Common Stock will be
treated as having received such cash in redemption of such fractional share
interest. Each such shareholder must determine his or her taxable gain or loss
on such redemption. The amount of gain or loss will be the difference between
the cash received and the basis of the fractional share interest surrendered.
Provided the FNB Common Stock and the fractional share interest were held as a
capital asset at the time of the redemption, such gain or loss will constitute
capital gain or loss, and such gain or loss will be long term capital gain or
loss if the holding period for such fractional share interest was greater than
one year.

        Holders of FNB Common Stock who do not participate in the Merger and who
receive cash pursuant to the exercise of dissenters' rights must consult with
their individual tax advisors to determine the correct income tax treatment of
such amount. Such tax treatment will depend upon the individual situation of
such holders; receipt of cash on exercise of dissenters' rights could either
constitute (i) a taxable proceed from the sale of FNB Common Stock or (ii) a
dividend distribution received on account of such stock.

        Shareholders of FNB stock who receive Norwest Common Stock pursuant to
the Merger will receive certain rights to acquire Norwest preferred stock under
certain circumstances. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" for
a list of the documents containing information concerning the preferred stock
purchase rights. Based upon the current ruling position of the IRS, such rights
will not constitute other property the receipt of which will be taxable to such
shareholders.

        FNB shareholders should also be aware that the IRS may examine
transactions taking place before, contemporaneously with, or after a
reorganization to determine whether reorganization treatment is appropriate, or
in some cases to determine whether shareholders will be taxed on other economic
benefits that are included as part of the overall transaction. 

                                       28
<PAGE>
 
Thus, loan transactions between parties, compensation arrangements, noncompete
agreements, consulting agreements, and other transactions could be reviewed by
the IRS and be determined to constitute taxable income to specific parties to
the Merger or could be a basis for assertion that reorganization treatment is
not appropriate for the Merger. Furthermore, if the IRS were to establish as to
some FNB shareholders that part of the Norwest Common Stock received in the
Merger is severable from the Merger, resulting in a proportionally increased
equity interest being received in the Merger by other FNB shareholders, FNB
shareholders whose equity interests were deemed to be constructively increased
by the Merger may be treated as having received a taxable stock dividend. THUS,
NOTWITHSTANDING THE TAX OPINION, SHAREHOLDERS SHOULD CONSULT WITH THEIR TAX
ADVISORS AS TO THE TAX CONSEQUENCES OF THE MERGER.

        Under Section 3406 of the Code, FNB shareholders may be subject to
"backup withholding" at the rate of 31% on "reportable payments" to be received
by them if they fail to furnish their correct taxpayer identification numbers or
for certain other reasons. Norwest will report to these persons and to the IRS
for each calendar year the amount of any reportable payments during that year
and the amount of tax withheld, if any, with respect to those reportable
payments.

        The Code also imposes an alternative minimum tax and excise taxes on
certain types of transactions. Applicability of such taxes is usually
controlled, in whole or in part, by other matters unrelated to the Merger or by
the unique characteristics of the particular taxpayer. ACCORDINGLY, FNB
SHAREHOLDERS ARE ENCOURAGED TO CONSULT THEIR TAX ADVISORS IF THEY ARE OR MIGHT
BE SUBJECT TO SUCH TAXES.

RESALE OF NORWEST COMMON STOCK

        The shares of Norwest Common Stock issuable to shareholders of FNB upon
the Merger becoming effective have been registered under the Securities Act.
Such shares may be traded freely and without restriction by those shareholders
not deemed to be "affiliates" of FNB or Norwest, as that term is defined in the
rules under the Securities Act. Norwest Common Stock received by those
shareholders of FNB who are deemed to be "affiliates" of FNB may be resold
without registration as provided for by Rule 145 or as otherwise permitted under
the Securities Act. Persons who may be deemed to be affiliates of FNB generally
include individuals or entities that control, are controlled by or are under
common control with, FNB and may include the executive officers and directors of
FNB as well as certain principal shareholders of FNB. In the Reorganization
Agreement, FNB has agreed to use its best efforts to obtain and deliver prior to
the Effective Time of the Merger signed representations by each executive
officer, director or shareholder of FNB who may reasonably be deemed an
affiliate of FNB 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 Merger except in compliance with the applicable provisions of the Securities
Act and the rules and regulations promulgated thereunder. (paragraph 4(k)) This
Proxy Statement-Prospectus does not cover any resales of Norwest Common Stock
received by affiliates of FNB.

STOCK EXCHANGE LISTING

        The Reorganization 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 the Merger becoming effective. Consummation of the
Merger is conditioned on the authorization for listing of such shares on the
NYSE and CHX. (paragraph 6)

                                       29
<PAGE>
 
ACCOUNTING TREATMENT

        Norwest will account for the acquisition of FNB using the purchase
method of accounting. For that reason, the consideration to be paid in the
Merger will be allocated to assets acquired and liabilities assumed based on
their estimated fair values at the Effective Time of the Merger and the results
of FNB's operations will be included in Norwest's results of operation from and
after the Effective Time of the Merger.

        The unaudited pro forma data  included in this Proxy Statement-
Prospectus for the Merger have been prepared using the purchase method of 
accounting.   See "SUMMARY--Comparative Per Common Share Data."

EXPENSES

        Except as otherwise provided in the Reorganization Agreement, Norwest
and FNB will each pay their own expenses in connection with the Merger,
including fees and expenses of their respective independent auditors and
counsel.

                          COMPARISON OF RIGHTS OF HOLDERS OF
                       FNB COMMON STOCK AND NORWEST COMMON STOCK

        The following is a comparison of certain rights of holders of FNB Common
Stock with the rights of holders of Norwest Common Stock. It is not intended to
be complete and is qualified in its entirety by reference to the relevant
provisions of the laws and documents discussed below. Additional information
concerning the rights of holders of Norwest Common Stock is provided in
Norwest's current report on Form 8-K filed with the Commission on May 1, 1996
and incorporated herein by reference. See "INCORPORATION OF CERTAIN DOCUMENTS BY
REFERENCE."

GENERAL

        FNB is incorporated under the laws of New Mexico. The rights of FNB's
shareholders are currently governed by the New Mexico Business Corporation Act
(the "NMBCA") and by FNB's articles of incorporation and bylaws (respectively,
the "FNB Articles" and "FNB Bylaws"). Norwest is incorporated under the laws of
Delaware. The rights of Norwest's stockholders are governed by the Delaware
General Corporation Law (the "DGCL") and by Norwest's certificate of
incorporation and bylaws (respectively, the "Norwest Certificate" and "Norwest
Bylaws"). If FNB's shareholders approve the Reorganization Agreement and the
Merger becomes effective, shareholders of FNB will become stockholders of
Norwest. For that reason, after the Effective Time of the Merger, their rights
will be governed by the DGCL and the Norwest Certificate and Norwest Bylaws.

        The NMBCA uses the term "shareholder" to refer to a holder of capital
stock of a New Mexico corporation. The DGCL uses the term "stockholder" to refer
to a holder of capital stock of a Delaware corporation. Accordingly, this Proxy
Statement-Prospectus uses the term shareholder to refer to a holder of FNB
Common Stock and the term stockholder to refer to a holder of Norwest Common
Stock.

CAPITAL STOCK

        FNB. The FNB Articles authorize the issuance of 100,000 shares of common
stock, par value $1.00 per share, and no shares of preferred stock. As of the
Record Date, 29,953 shares of FNB Common Stock were issued and outstanding.
Since no shares of preferred stock are authorized, issued or outstanding by FNB
as of the date of this Proxy Statement-Prospectus, no class or series has any
preference over the FNB Common Stock with respect to dividends and distributions
upon the liquidation of FNB.

        NORWEST. The Norwest Certificate currently authorizes the issuance of
500,000,000 shares of Norwest Common Stock, 5,000,000 shares of preferred stock,
without par value, and 4,000,000 shares of preference stock, without par value.
Norwest's stockholders have approved an amendment to the Norwest Certificate to
increase the authorized shares of Norwest Common Stock to 1,000,000,000 shares.
For a description of the Norwest Common Stock and certain rights and
restrictions relating thereto and for certain information concerning Norwest
preferred stock and preference stock, see Norwest's current report on Form 8-K
filed on May 1, 1996 and Norwest's registration statement on Form 8-A dated
December 6, 1988, as amended pursuant to Form 8-A/A dated June 29, 1993. Copies
of these documents may be obtained as provided in the section entitled
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."

DIRECTORS

                                       31
<PAGE>
 
        FNB. The FNB Bylaws provide for a board of directors of ten members of
at least 18 years of age, subject to decrease to as few as five members and
increase to as many as 25 members upon the affirmative vote of a majority of the
members of the board of directors. Directors are elected at the annual meeting
of the shareholders of FNB by the affirmative vote of a majority of a quorum and
hold office until the next annual meeting of shareholders and thereafter until a
successor has been elected and qualified. Directors are removable with or
without cause by the vote of the holders of a majority of the shares entitled to
vote in an election of directors at a meeting of shareholders called expressly
for that purpose. Vacancies in the FNB Board are filled by the affirmative vote
of the remaining directors, though less than a quorum, and the person so elected
serves the unexpired term of his predecessor. The FNB Articles require that
directors be elected by cumulative voting.

        NORWEST. The Norwest Bylaws provide for a board of directors consisting
of not less than 10 nor more than 23 persons, each serving for a term of one
year or until his or her earlier death, resignation or removal. The number of
directors of Norwest is currently fixed at 16. Directors of Norwest may be
removed with or without cause by the affirmative vote of the holders of a
majority of the shares of Norwest capital stock entitled to vote thereon.
Vacancies on the Norwest Board may be filled by a majority of the remaining
directors or, in the event a vacancy is not so filled or if no director remains,
by the stockholders. Directors of Norwest are elected by plurality of the votes
of shares of Norwest capital stock entitled to vote thereon present in person or
by proxy at the meeting at which directors are elected. The Norwest Certificate
does not currently permit cumulative voting in the election of directors.

AMENDMENT OF CERTIFICATE OF INCORPORATION AND BYLAWS

        FNB. Generally, under the NMBCA, amendments to articles of incorporation
require the affirmative vote of the holders of a majority of the shares entitled
to vote on the proposed amendment. Where class voting is required by the NMBCA,
approval requires the affirmative vote of the holders of both a majority of the
shares of each class entitled to vote on the proposed amendment and a majority
of the total shares entitled to vote thereon. The FNB Bylaws provide that the
board of directors may alter, amend, or repeal the FNB Bylaws, in whole or in
part, from time to time.

        NORWEST. The Norwest Certificate may be amended only if the proposed
amendment is approved by the Norwest Board and thereafter approved by a majority
of the outstanding stock entitled to vote thereon and by a majority of the
outstanding stock of each class entitled to vote thereon as a class. The Norwest
Bylaws may be amended by a majority of the Norwest Board or by a majority of the
outstanding stock entitled to vote thereon. Shares of Norwest Preferred Stock
and Norwest Preference Stock currently authorized in the Norwest Certificate may
be issued by the Norwest Board without amending the Norwest Certificate or
otherwise obtaining the approval of Norwest's stockholders.

                                       32
<PAGE>
 
SHAREHOLDER APPROVAL OF MERGERS AND ASSET SALES

        In addition to being subject to the laws of New Mexico and Delaware,
respectively, as discussed below, both FNB and Norwest, as bank holding
companies, are subject to various provisions of federal law with respect to
mergers, consolidations and certain other corporate transactions. See "CERTAIN
REGULATORY AND OTHER CONSIDERATIONS PERTAINING TO NORWEST."

        FNB. Except as described below, the affirmative vote of a majority of
the outstanding shares of FNB Common Stock entitled to vote thereon (unless any
class of shares is entitled to vote thereon as a class, in which event approval
of a majority of the shares entitled to vote as a class and of the total shares
entitled to vote thereon) is required to approve an amendment to the FNB
Articles, a merger or consolidation involving FNB, a sale, lease, exchange or
other disposition of all or substantially all of FNB's assets outside the normal
course of business or the voluntary dissolution of FNB. Approval of a merger or
sale of assets transaction by the shareholders at a meeting thereof requires
that notice be given in the manner provided in the NMBCA and the FNB Bylaws at
least 20 days prior to the date of the meeting. No vote of shareholders is
required, however, with respect to a merger in which FNB is the surviving
corporation and owns at least 90% of the merged corporation's shares prior to
the merger.

        NORWEST. Except as described below, the affirmative vote of a majority
of the outstanding shares of Norwest Common Stock entitled to vote thereon is
required to approve a merger or consolidation involving Norwest or the sale,
lease or exchange of all or substantially all of Norwest's corporate assets. No
vote of the stockholders is required, however, in connection with a merger in
which Norwest is the surviving corporation and (i) the agreement of merger for
the merger does not amend in any respect the Norwest Certificate, (ii) each
share of capital stock outstanding immediately before the merger is to be an
identical outstanding or treasury share of Norwest after the merger, and (iii)
the number of shares of capital 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's capital stock outstanding
immediately before the merger.

APPRAISAL RIGHTS

        FNB. Under the NMBCA, shareholders of FNB are entitled to exercise
dissenters' rights and obtain payment of the fair value of their shares in cash
if FNB engages in certain transactions. The transactions which give rise to
dissenters' rights under New Mexico law are (i) mergers and consolidations to
which the corporation is a party (unless the shareholders of the surviving
corporation are not entitled to a vote with respect thereto); (ii) any sale or
exchange of all or substantially all of the property and assets of the
corporation not made in the usual and regular course of business, including a
sale in dissolution, but excluding a sale pursuant to a court order or a sale
for cash on terms requiring that all or substantially all of the net proceeds of
sale be distributed to the shareholders in accordance with their respective
interests within one year of the sale; (iii) any plan of exchange to which the
corporation is a party as the corporation the shares of which are to be
acquired; (iv) any amendment to the articles of incorporation which materially
and adversely affects the rights appurtenant to the shares of the dissenting
shareholders by altering or abolishing a preferential right of the shares,
creating, altering or abolishing a redemption or sinking fund right in respect
of the shares, or excluding or limiting the right of any holder of such to
shares to vote on any manner, or to cumulate his votes; and (v) any other
corporate action for which the articles of incorporation, bylaws, or

                                       33
<PAGE>
 
a resolution of the board of directors provides for a right to dissent. See the
more detailed discussion under the caption "THE MERGER--Dissenters' Rights."

        NORWEST. Section 262 of the DGCL provides for stockholder appraisal
rights in connection with mergers and consolidations generally; however,
appraisal rights are not available to holders of any class or series of stock
that, at the record date fixed to determine stockholders entitled to receive
notice of and to vote at the meeting to act upon the agreement of merger or
consolidation, were either (i) listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or (ii) held of
record by more than 2,000 stockholders, so long as stockholders receive shares
of the surviving corporation or another corporation whose shares are so listed
or designated or held by more than 2,000 stockholders. Norwest Common Stock is
listed on the NYSE and the CHX and currently held by more than 2,000
stockholders. For these reasons, assuming that the other conditions described
above are satisfied, holders of Norwest Common Stock will not have appraisal
rights in connection with mergers and consolidations involving Norwest.

SPECIAL MEETINGS

        FNB. Under the NMBCA, a special meeting of FNB's shareholders may be
called by the President, the FNB Board, the holders of not less than ten percent
of all of the shares entitled to vote at the meeting and such other persons as
may be authorized by the articles of incorporation or bylaws. The FNB Bylaws
permit special meetings of shareholders to be called by the persons authorized
by the NMBCA to call such meetings, and do not authorize any additional persons
to call such meetings.

        NORWEST. Under the DGCL, special meetings of stockholders may be called
by the board of directors or by such persons as may be authorized in the
certificate of incorporation or bylaws. The Norwest Bylaws provide that 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 Norwest Board. As such,
holders of Norwest Common Stock do not have the ability to call a special
meeting of stockholders.

DIRECTORS DUTIES

        FNB. Under the NMBCA, a director is required to perform his or her
duties as a director in good faith, in a manner he or she believes to be in or
not opposed to the best interests of the corporation, and with such care as an
ordinarily prudent person would use under similar circumstances in a like
position. The NMBCA further provides that in determining what is in or not
opposed to the best interests of the corporation, a director must consider the
interests of the corporation's shareholders and may consider (i) the interests
of the corporation's employees, suppliers, creditors, and customers; (ii) the
economy of the state and the nation; (iii) the impact of any action upon the
communities in or near which the corporation's facilities or operations are
located; and (iv) the long-term interests of the corporation and its
shareholders, including the possibility that those interests may be best served
by the continued independence of the corporation.

        NORWEST. Unlike the NMBCA, the DGCL does not specifically enumerate
directors' duties. In addition, the DGCL does not contain any provision
equivalent to the New Mexico statute specifying what factors a director must and
may consider in determining a corporation's best interests. However, judicial
decisions in Delaware have established that 

                                       34
<PAGE>
 
directors, in performing their duties, are bound to use that amount of care
which ordinarily prudent men would use in similar circumstances.

ACTION WITHOUT A MEETING

        FNB. Under the NMBCA and the FNB Bylaws, any action required or
permitted to be taken at a meeting of the FNB Board (including a committee
thereof) or shareholders of FNB may be taken without a meeting if a consent in
writing, setting forth the action so taken, is signed by all of the directors
(or committee members), or all of the shareholders entitled to vote with respect
to the subject matter thereof, as the case may be. Such consent has the effect
as a unanimous vote of the Board (or the committee thereof) or the shareholders,
as applicable. Action by less than unanimous consent of the Board or the
shareholders is not permitted under the NMBCA or the FNB Bylaws.

        NORWEST. As permitted by Section 228 of the DGCL and the Norwest
Certificate, any action required or permitted to be taken at a stockholders'
meeting may be taken without a meeting pursuant to the written consent of the
holders of the number of shares that would have been required to effect the
action at an actual meeting of the stockholders.

LIMITATION OF DIRECTOR LIABILITY

        FNB. Unlike the DGCL, the NMBCA does not contain any provisions limiting
or eliminating the liability of the directors of a New Mexico corporation for
monetary damages for a breach by a director of his fiduciary duty as a director.

        NORWEST. The Norwest Certificate provides that a director (including an
officer who is also a director) of Norwest shall not be liable personally to
Norwest or its stockholders for monetary damages for breach of fiduciary duty as
a director, except for liability arising out of (i) any breach of the director's
duty of loyalty to Norwest or its stockholders, (ii) acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) payment of a dividend or approval of a stock repurchase in violation
of Section 174 of the DGCL, or (iv) any transaction from which the director
derived an improper personal benefit. This provision protects Norwest's
directors against personal liability for monetary damages from breaches of their
duty of care. It does not eliminate the director's duty of care and has no
effect on the availability of equitable remedies, such as an injunction or
rescission, based upon a director's breach of his duty of care.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

        FNB. Under the NMBCA and the FNB Bylaws, a director of FNB is not liable
for any action taken as a director or for any failure to take any action if he
or she performed the duties of a director's office in good faith, with the care
an ordinarily prudent person in a similar position would exercise under similar
circumstances, and in a manner the director believes to be in the best interests
of the corporation.

        Under the NMBCA and the FNB Bylaws, FNB may indemnify its officers and
directors made a party to any proceeding, whether civil or criminal, from any
judgments, penalties, fines, settlements, and reasonable expenses, including
attorneys' fees, if such person was made a party to the action by reason of the
fact that he or she was an officer or director of FNB and he or she conducted
himself or herself in good faith and reasonably believed (i) in the case of
conduct in his or her official capacity with FNB, that his or her conduct was in
the best interests of FNB; (ii) in all other cases, that his or her conduct was
at least not 

                                       35
<PAGE>
 
opposed to FNB's best interests; and (iii) in the case of criminal proceedings,
that he or she had no reasonable cause to believe the conduct was unlawful.

        No indemnification is available where the officer or director is
adjudged liable to FNB or in which the officer or director has been adjudged
liable on the basis that he or she improperly received a personal benefit. If
the FNB Board is of the opinion, reasonably based on the facts, circumstances,
and outcome of the proceeding, that the director has been wholly successful, on
the merits or otherwise, in the defense of the proceeding, then indemnification
of the director for reasonable expenses incurred in the proceeding is mandatory.
A court of appropriate jurisdiction, upon application of the director, may order
indemnification if the court determines that the director has been wholly
successful in the defense of the proceeding or if the court determines that the
director is fairly and reasonably entitled to indemnification in view of all the
relevant circumstances, whether or not the director has met the statutory
standards of conduct or has been liable for receiving an improper personal
benefit. If the action was by or in the right of FNB (a "derivative action"),
indemnification is only available for any reasonable expenses incurred.

        The FNB Bylaws provide that expenses incurred in defending any action
may be paid by FNB in advance of the final disposition of such action upon
receipt of an undertaking by a director or officer to repay such amount unless
it is ultimately determined that he or she is entitled to be indemnified. The
indemnification provided by the FNB Bylaws is substantially similar to the
indemnification provisions in the NMBCA.

        NORWEST. The Norwest Certificate provides that Norwest must indemnify,
to the fullest extent authorized by the DGCL, each person who was or is made a
party to, is threatened to be made a party to, or is involved in, any action,
suit, or proceeding because he is or was a director or officer of Norwest (or
was serving at the request of Norwest as a director, trustee, officer, employee,
or agent of another entity) while serving in such capacity against all expenses,
liabilities, or loss incurred by such person in connection therewith, provided
that indemnification in connection with a proceeding brought by such person will
be permitted only if the proceeding was authorized by the Norwest Board. The
Norwest Certificate also provides that Norwest must pay expenses incurred in
defending the proceedings specified above in advance of their final disposition,
provided that if so required by the DGCL, such advance payments for expenses
incurred by a director or officer may be made only if he undertakes to repay all
amounts so advanced if it is ultimately determined that the person receiving
such payments is not entitled to be indemnified.

        The Norwest Certificate authorizes Norwest to provide similar
indemnification to employees or agents of Norwest.

        Pursuant to the Norwest Certificate, Norwest may maintain insurance, at
its expense, to protect itself and any directors, officers, employees or agents
of Norwest or another entity against any expense, liability or loss, regardless
of whether Norwest has the power or obligation to indemnify that person against
such expense, liability or loss under the DGCL.

        The right to indemnification is not exclusive of any other right which
any person may have or acquire under any statute, provision of the Norwest
Certificate or Norwest Bylaws, agreement, vote of stockholders or disinterested
directors or otherwise.

DIVIDENDS

                                       36
<PAGE>
 
        In addition to restrictions imposed under New Mexico and Delaware law,
respectively, as discussed below, FNB and Norwest are subject to Federal Reserve
Board policies regarding payment of dividends, which generally limit dividends
to operating earnings. See "CERTAIN REGULATORY AND OTHER CONSIDERATIONS
PERTAINING TO NORWEST."

        FNB. Under the NMBCA, FNB's Board of Directors may authorize and FNB may
pay dividends to its shareholders, provided that no such distribution of
dividends may be made if, after giving effect thereto, either (i) FNB would be
unable to pay its debts as they become due in the usual course of its business
or (ii) FNB's total assets would be less than the sum of its total liabilities
and the amount payable, in any liquidation, in respect of all shares having
liquidation preference.

        NORWEST. Delaware corporations may pay dividends out of surplus or, if
there is no surplus, out of net profits for the fiscal year in which declared
and for the preceding fiscal year. Section 170 of the DGCL also provides that
dividends may not be paid out of net profits if, after the payment of the
dividend, capital is less than the capital represented by the outstanding stock
of all classes having a preference upon the distribution of assets.

CORPORATE GOVERNANCE PROCEDURES; NOMINATION OF DIRECTORS

        FNB. Unlike the Norwest Bylaws, the FNB Bylaws do not contain any
advance notice requirements or other information procedures to be followed in
order to nominate a person to serve as a director or to propose an item of
business for consideration at a meeting of FNB shareholders.

        NORWEST. The Norwest Bylaws contain detailed advance notice and
informational procedures which must be complied with in order for a stockholder
to nominate a person to serve as a director. The Norwest Bylaws generally
require a stockholder to give notice of a proposed nominee in advance of the
stockholders meeting at which directors will be elected. In addition, the
Norwest Bylaws contain detailed advance notice and informational procedures
which must be followed in order for a Norwest stockholder to propose an item of
business for consideration at a meeting of Norwest stockholders.

                          INFORMATION ABOUT FNB AND THE BANK

GENERAL

        FNB is a one-bank holding company registered under the Bank Holding
Company Act. FNB was incorporated and organized as a New Mexico business
corporation in 1986 for the purpose of acquiring the Bank and the First National
Bank of Santa Rosa, which acquisition was completed in 1986. The First National
Bank of Santa Rosa was merged into the Bank in 1993. FNB's principal executive
offices are located at 302 South First Street, Tucumcari, New Mexico 88401, and
its telephone number at that address is (505) 461-3602.

        The Bank is a national banking association chartered in 1901, which has
its principal place of business at 302 South First Street, Tucumcari, New Mexico
88401. It has branches located in the towns of Santa Rosa and Las Vegas, New
Mexico. The Bank's market area consists primarily of areas located principally
within Quay, San Miguel, and Guadalupe counties, New Mexico, and to a lesser
extent parts of Harding, Curry and DeBaca counties. The Bank had total assets of
approximately $92.2 million at December 31, 1996. The Bank is a full service,
independent community bank which provides a full range of commercial banking
services, including traditional deposit services and commercial, interim
construction, consumer, home improvement, real estate, agricultural, and
industrial loans.

REGULATION AND SUPERVISION

        As a bank holding company, FNB is subject to regulation by and files
quarterly reports with the Federal Reserve Board. The Federal Reserve Board is
authorized to conduct examinations of FNB and any of its subsidiaries. The
Federal Reserve Board may also exercise cease and desist powers over bank
holding companies and their nonbank affiliates if their actions represent unsafe
or unsound practices or violations of law.

        The Bank and its operations are affected by various restrictions and
requirements under the laws of the United States and the State of New Mexico.
Under these generally applicable federal and state restrictions and
requirements, the Bank must maintain reserves against deposits and is restricted
with respect to the nature and amount of loans which it may make, the interest
that it may charge on those loans and the conditions under which it may pay
dividends on its capital stock.

PROPERTIES

        FNB conducts its operations in the Bank's principal offices located at
302 South First Street, Tucumcari, New Mexico. The principal asset of FNB is the
common stock of the Bank. As a bank holding company, FNB conducts its operations
through its subsidiary, the Bank.

        The Bank owns its principal executive offices and main banking facility
in Tucumcari, New Mexico, as well as its branch location in Santa Rosa, New
Mexico. It leases its branch in Las Vegas from Furr's Supermarkets, Inc. under a
five-year lease expiring in 2001. Set forth below is certain information
regarding the principal properties of FNB and the Bank:

        The Bank's main banking facility consists of a single structure located
in Tucumcari, New Mexico. The main facility is a 30,000 square foot structure
which houses the Bank's lending and teller operations, accounting, computer, and
electronic data processing facilities, as well as the executive offices of the
Bank and FNB. The branch in Las Vegas is located inside a Furr's supermarket.
The Santa Rosa branch is a single-story building. In addition to its banking
facilities, FNB owns an 4,080 square foot warehouse in Tucumcari used for
storage.

COMPETITION

        The Bank experiences competition in both attracting deposits and lending
funds. Competition in lending comes principally from other commercial banks,
credit unions, savings and loan associations, the farm credit system, and
various regional and national brokerage firms offering alternative financial
products in the Bank's market area. To a lesser extent, the Bank competes with
mortgage companies and insurance companies. Competition for deposits comes
principally from other commercial banks, savings and loan associations, and
credit unions. The primary factors in competing for deposits among these
institutions are interest rates paid on accounts and extent of services offered.

LEGAL PROCEEDINGS

        The nature of the Bank's business causes it to be involved in routine
legal proceedings from time to time. Management of the Bank believes that there
are no pending or threatened legal proceedings which, upon resolution, would
have a material adverse effect on the financial condition or results of
operation of the Bank.

        INTERESTS OF MANAGEMENT AND OTHERS IN CERTAIN TRANSACTIONS

        In considering the recommendation of the FNB Board of Directors with
respect to the Reorganization Agreement, shareholders should be aware that
certain executive officers and directors of FNB have certain interests in the
Merger that are in addition to the interests of the shareholders of FNB
generally. The FNB Board of Directors was aware of these interests and
considered them, among other matters, in approving the Reorganization Agreement.

        Pursuant to the Reorganization Agreement, Norwest has agreed, among
other things, to (i) indemnify FNB's directors and executive officers for any
claims arising out of the Merger, (ii) for a period of three years after the
Effective Time of the Merger, use its best efforts to continue in force FNB's
existing directors' and officers' liability insurance for pre-closing claims
arising out of occurrences prior to the Effective Time of the Merger, provided
that the cost to do so does not exceed 125% of the pre-closing cost of such
insurance, and (iii) ensure that all rights to indemnification in FNB's Articles
of Incorporation and Bylaws, and in the Articles of Association and Bylaws of
the Bank, as in effect prior to the merger, shall, with respect to claims
arising out of occurrences prior to the Effective Time of the Merger and with
respect to those persons who are covered by such provisions prior to the
Effective Time of the Merger, survive the Merger and continue in full force and
effect.

        Certain of the principal shareholders of FNB and the directors and
executive officers of FNB and the Bank are presently customers of the Bank or
are officers, directors, or shareholders of corporations, or owners of a
participation or other interest in entities or ventures which currently have or
in the past have had transactions with the Bank. In order to comply with
regulations promulgated under the Federal Reserve Act, such transactions are
required to be made in the ordinary course of business of the Bank, on
substantially the same terms, including interest rate, collateral, and repayment
terms, as those prevailing at the time for comparable transactions with other
persons not affiliated with the Bank or FNB, and should not involve more than
the normal risk of collectability or present other unfavorable features. The
aggregate indebtedness to the Bank of its and FNB's principal shareholders,
executive officers, and directors, and their affiliates, directly or indirectly,
as of February 28, 1997, was $1,491,381 or approximately 15.3% of shareholders'
equity at such date.

        No loans to any director or executive officer of FNB or the Bank or any
of the respective "associates" of such person are past due, on non-accrual,
restructured, considered a potential problem loan, or classified as substandard,
doubtful, or loss by regulatory examiners.

        As of the record date, the directors and executive officers of FNB owned
approximately 22,787 shares of FNB Common Stock, representing 76.1% of such
class. Such shares will be converted into shares of Norwest Common Stock in the
Merger on the same basis as the shares of FNB Common Stock held by the other FNB
shareholders. Each of the directors and executive officers of FNB has separately
indicated his intention to vote in favor of the Merger.

        Employment Agreements. It is a condition to the obligations of Norwest
to consummate the transactions contemplated by the Reorganization Agreement that
Messrs. Barton Jones and Craig Cosner execute and deliver employment agreements
with Norwest containing terms and conditions satisfactory to Norwest.

        Mr. Jones has entered into an Employment and Non-Competition Agreement
with Norwest and the Bank dated as of January 30, 1997, which provides for Mr.
Jones' employment by Norwest as Chairman and Chief Executive Officer of the Bank
for a one year period effective the date immediately following the closing of
the acquisition. Mr. Jones will receive a salary of $99,100 per year during the
term of the agreement, and will be eligible to participate in all Norwest
benefit plans available to regular employees of Norwest in similar positions,
other than the Norwest Corporation Severance Pay Plan. The agreement terminates
on the earlier of the expiration of the one year term, or employee's death,
voluntary resignation or termination by Norwest for fraud, dishonesty or the
violation of Norwest's Code of Ethics. The agreement provides that, at the end
of its stated term, Mr. Jones will be paid a separation payment of $75,000
payable in two equal installments, the first at the end of the employment term
and the second nine months thereafter. The separation payment is made in
consideration of Mr. Jones' agreement that for a period of 18 months after the
end of the employment term he will not, by himself or through others, directly
or indirectly engage in the business of banking within the counties of Quay,
Guadalupe, Harding, Curry and San Miguel, New Mexico, including but not limited
to (i) engaging in the commercial banking or thrift business, (ii) aiding or
assisting anyone in engaging in the commercial banking or thrift business, (iii)
reestablishing or reopening any business similar to the business of Norwest or
its successor, (iv) in any manner becoming interested directly or indirectly, as
employee, owner, partner, shareholder, director, officer or otherwise, in a
commercial banking or thrift business (excluding stock ownership of less than
five percent in public corporations), (v) disclosing any confidential or
proprietary information regarding any customer or prospective customer of
Norwest or the Bank or any product, service or system thereof, (vi) soliciting
any employee of Norwest or the Bank for the purpose of encouraging that employee
to leave the employee of Norwest or the Bank, or (vii) attempting to divert any
of the business that Norwest has a reasonable expectation of obtaining by
soliciting, contacting or communicating with any customer or potential customer
of Norwest or the Bank for its products or services.

        Mr. Cosner has entered into an Employment and Non-Competition Agreement
with Norwest and the Bank dated as of January 30, 1997, which provides for Mr.
Cosner's employment by Norwest as President and Chief Operating Officer of the
Bank for a one year period effective the date immediately following the closing
of the acquisition. Mr. Cosner will receive a salary of $90,000 per year during
the term of the agreement, and will be eligible to participate in all Norwest
benefit plans available to regular employees of Norwest in similar positions,
other than the Norwest Corporation Severance Pay Plan. The agreement terminates
on the earlier of the expiration of the one year term, or employees' death,
voluntary resignation or termination by Norwest for fraud, dishonesty or the
violation of Norwest's Code of Ethics. The agreement provides that, at the end
of its stated term, Mr. Cosner will be paid a separation payment of $50,000
payable in two equal installments, the first at the end of the employment term
and the second six months thereafter. The separation payment is made in
consideration of Mr. Cosner's agreement that for a period of 12 months after the
end of the employment term he will not, by himself or through others, directly
or indirectly engage in the business of banking within the counties of Quay,
Guadalupe, Harding, Curry and San Miguel, New Mexico, including but not limited
to (i) engaging in the commercial banking or thrift business, (ii) aiding or
assisting anyone in engaging in the commercial banking or thrift business, (iii)
reestablishing or reopening any business similar to the business of Norwest or
its successor, (iv) in any manner becoming interested directly or indirectly, as
employee, owner, partner, shareholder, director, officer or otherwise, in a
commercial banking or thrift business (excluding stock ownership of less than
five percent in public corporations), (v) disclosing any confidential or
proprietary information regarding any customer or prospective customer of
Norwest or the Bank or any product, service or system thereof, (vi) soliciting
any employee of Norwest or the Bank for the purpose of encouraging that employee
to leave the employee of Norwest or the Bank, or 

                                       44

(vii) attempting to divert any of the business that Norwest has a reasonable
expectation of obtaining by soliciting, contacting or communicating with any
customer or potential customer of Norwest or the Bank for its products or
services.

        Settlement of Salary Continuation Agreements. In 1985, the Bank entered
into Salary Continuation Agreements with nine of its officers requiring the
payment of additional compensation by the Bank to such employees or their
designated beneficiaries for a period of time after employee's retirement from
active service with the Bank, or termination of such employment by reason of the
employee's death. The agreements provided for a fixed benefit based on the
officer's salary at that time, to be paid over a ten year period. These nine
employees include Messrs. Barton Jones, Craig Cosner and Bruce Thomas, Ms. Judy
Aragon and Ms. Patsy Gresham, each of whom is either a director or executive
officer of FNB. The Reorganization Agreement requires that FNB, as soon as
practicable after execution of the Reorganization Agreement, but in any event
prior to closing, offer each FNB officer or employee who is a party to an
outstanding Salary Continuation Agreement with FNB or the Bank the opportunity
to terminate such agreement in consideration of the receipt of a cash payment
equal to the present value of the Salary Continuation Agreement calculated using
a discount rate reasonably acceptable to Norwest. As required by the
Reorganization Agreement, FNB has offered to the nine employees who are parties
to such agreements the sum of $373,004 in the aggregate in termination of such
agreements, with such termination to be effective, and such payment to be due,
contemporaneously with the consummation of the Merger. Of such amount, Messrs.
Barton Jones, Cosner and Thomas, and Ms. Aragon and Ms. Gresham, were offered
$139,086, $69,809, $66,520, $17,392 and $29,841, respectively, to terminate
their Salary Continuation Agreements, and each of them has accepted such offer
and entered into a Termination Agreement with FNB and the Bank providing for
such payment. All of the remaining officers have also accepted the offer to
terminate their Salary Continuation Agreements.

                 FNB MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                          CONDITION AND RESULTS OF OPERATION

GENERAL

    The following is FNB management's discussion and analysis of the significant
factors affecting FNB's results of operations and financial condition. This
should be read in conjunction with FNB's audited and unaudited consolidated
financial statements and accompanying footnotes and other selected financial
data presented elsewhere herein.

    FNB, a one bank holding company headquartered in Tucumcari, New Mexico,
derives substantially all of its revenues and income from the operation of its
wholly-owned subsidiary, the Bank. The Bank is a full service, independent
community bank that provides a full range of commercial banking services. See
"INFORMATION ABOUT FNB AND THE BANK--General." References to the operations of
FNB include the operations of the Bank, unless the context otherwise requires.

    FNB's earnings depend primarily on the Bank's net interest income, the
difference between the income earned on the Bank's loans and investments and the
interest paid on its deposits. Among the factors affecting net interest income
are the type, volume and quality of the Bank's assets, the type and volume of
its deposits, and the relative sensitivity of the Bank's interest earning assets
and its interest bearing deposits to changes in interest rates. See "--Certain
Selected Statistical Information-- Average Balance Sheets and Average Yields
Earned and Rates Paid." In addition, the Bank's income is significantly affected
by the fees it receives from other banking services, by its required provisions
for loan losses and by the level of its operating expenses. All aspects of the
Bank's operations are affected generally by market, economic and competitive
conditions, particularly those in Eastern New Mexico.

FINANCIAL CONDITION

    Total assets increased by $3,047,275, or 3.4%, during 1996 to $92,200,520 at
December 31, 1996 following an increase of $1,475,878 or 1.7%, during 1995 to
$89,153,245 at December 31, 1995. The increase in 1996 was primarily the result
of opening the Las Vegas, New Mexico branch and an increase in deposits of
$2,613,877 and net earnings of $635,096. The increase in 1995 was primarily the
result of an increase in deposits of $313,000 and net earnings of $779,782.

    Loans increased approximately 2.8% during 1996 by $1,635,223 to $59,655,309
at December 31, 1996, and increased $748,438 during 1995 to $58,020,286 at
December 31, 1995. The increase in loans during 1996 was primarily the result of
new loans in Las Vegas, New Mexico. The increase in loans in 1995 was primarily
attributable to increases in demand for all classes of loans.

    Investment securities decreased during 1996 by $969,554, or 5.4%, to
$17,047,817 at December 31, 1996 and increased $3,400,037, or 23.3%, during 1995
to $18,017,371 at December 31, 1995. The increases during 1995 occurred
primarily in securities of the U.S. Treasury, U.S. Government Agencies and state
and political subdivisions. The decrease during 1996 was primarily used to fund
an increase in loans to customers and is largely attributable to the opening of
the Las Vegas branch and strong loan demand. The 1995 increase was funded by a
decrease in federal funds sold.

RESULTS OF OPERATIONS

    Net interest income is the primary source of income for FNB and represents
the amount by which interest and fees generated by earning assets exceed the
cost of funds, primarily interest paid to the Banks' depositors on interest
bearing accounts. The "interest rate spread" is the difference in the average
annual interest rate received by the Bank on its interest earning assets and the
average annual interest rate paid by the Bank on its interest bearing
liabilities. The "net interest margin" is the quotient obtained by dividing net
interest income by average earning assets, and thus takes into account any
imbalance between the volume of interest earning assets when compared to the
volume of interest bearing liabilities, which is not considered in the
calculation of interest rate spread. Where net interest margin exceeds interest
rate spread, it usually means that the volume of interest earning assets (such
as loans) exceeds the volume of interest bearing liabilities (such as interest
bearing deposits).

    COMPARISON OF YEARS ENDED DECEMBER 31, 1996 AND 1995

    EARNINGS PERFORMANCE

    FNB earned net income of $635,096 in 1996 and $779,782 in 1995. The 18.6%
decrease in net income of $144,686 in 1996 compared to 1995 is attributable to
increases in non-interest expenses and income taxes of $326,723 (or 8.9%) and
$130,850 (or 58.2%), respectively, partially offset by a 4.9% increase in net
interest income of $191,585 and a 16.0% increase in non-interest income of
$138,307. The increase in income taxes in 1996 was attributable to the recording
of a deferred tax asset during 1995 resulting from the unrealized loss on
investments included in stockholders' equity and changes in other timing
differences. Non-interest expenses increased principally because of the startup
costs of opening the Las Vegas, New Mexico branch.

    The consolidated return on average assets was .7% in 1996 compared to .9% in
1995. Return on average stockholders' equity was 7.2% in 1996 compared to 9.3%
in 1995. The decline in these ratios was primarily attributable to the decreases
in net income discussed in the preceding paragraph. On a per share basis, net
income for the years 1996 and 1995 was $21.20 and $26.03, respectively.

    The following is a condensed summary of the statements of operations:

    NET INTEREST INCOME

    FNB's net interest income is affected by changes in yields earned on
interest earning assets and rates paid on interest bearing deposits and other
borrowed funds, referred to as "rate change." It is also affected by changes in
the amount and mix of interest earning assets and interest bearing liabilities,
referred to as "volume change."

    The following table is provided to show the percentage of change in interest
income and expense from significant interest-bearing assets and liabilities:

    Net interest income increased from $3,918,408 in 1995 to $4,109,993 in 1996,
an improvement of 4.9%. During the year ended December 31, 1996, interest rates
in the United States were generally stable.

    Total interest income increased to $6,865,439 or 3.8% in 1996 as compared to
$6,613,484 in 1995. Earning asset yields were increased slightly to 8.82% in
1996 from 8.56% in 1995. The higher net interest income was also attributable to
a 2.1% increase in average loans to $58,838,000 in 1996, compared to $57,646,000
in 1995. See "--Certain Selected Statistical Information" for information
regarding FNB's average balances during the two years ended December 31, 1996
and 1995.

    Total interest expense in 1996 of $2,775,446 increased 2.2% from $2,695,076
in 1995. This increase was attributable primarily to an increase in average
interest-bearing liabilities of $1,925,000 in 1996 from 1995. The interest rate
paid on interest bearing deposits remained essentially unchanged from 1995 to
1996.

        PROVISION FOR LOAN LOSSES

    The provision for loan losses is charged to earnings to bring the total
allowance for loan losses to a level deemed appropriate by management based on
management's evaluation of the loan portfolio, economic conditions, prior loss
experience, review of specific problem loans, and other pertinent factors.
Actual losses on loans are charged against the allowance and recoveries on
charged-off loans are credited to the allowance. FNB's provision for loan losses
was $107,005 and $90,000 in 1996 and 1995, respectively. See "--Comparison of
the Years Ended December 31,1996 and 1995--Earnings Performance." Net loans
charged off were $89,176 and $64,778 in 1996 and 1995, respectively.

    The allowance for loan losses as a percentage of loans was .92% at December
31,1996 and at December 31, 1995.

    The Bank's principal source of non-interest income is service charges on
deposit accounts. Other sources are dividends from life insurance policies owned
by the Bank, dividends, and a variety of other service charges and fees,
including safe deposit box rental and printed check sales.

    Non-interest income increased 16.0% to $998,985 in 1996 compared to $860,679
in 1995. The increase in 1996 was primarily due to an increase in service
charges on deposit accounts.

</TABLE> 

    Total non-interest expense increased 8.9% to $4,010,877 in 1996, compared to
$3,684,154 in 1995. These increases were largely attributable to increases in
salaries and benefits and professional fees related to the opening of the Las
Vegas bank. FDIC insurance assessments decreased to $37,898 in 1996 from
$122,978 in 1995. The decrease was primarily due to decreased premium rates and
examination timing in these periods.

    INCOME TAXES

    FNB is subject to Federal and New Mexico income taxes which fluctuate from
period to period with fluctuations in FNB's earnings performance. Income taxes,
as a percentage of net income before income taxes, increased from 22.4% in 1995
to 35.9% in 1996 due to the recording of a deferred tax asset during 1995
resulting from the unrealized loss on investments included in stockholders'
equity and changes in other timing differences.

    STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS

    In February 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 109 ("SFAS 109"), "Accounting for Income
Taxes." Under SFAS 109, deferred tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. The effect
on deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date. During 1995, 

                                       52
<PAGE>
 
FNB adopted SFAS 109. The change in method of accounting for income taxes had no
significant effect except for the recording of a deferred tax asset as described
above.

    The Financial Accounting Standards Board has issued Statement 114 ("SFAS
114"), "Accounting by Creditors for Impairment of a Loan" and Statement 118
("SFAS 118"), "Accounting by Creditors for Impairment of a Loan -- Income
Recognition and Disclosures." These Statements apply to all creditors and all
loans, including those that are restructured in troubled debt restructurings
with a modification of terms. Excluded are large groups of homogeneous loans
with small balances that are evaluated collectively, loans measured at fair
value or at the lower of cost or fair value, leases and debt securities. SFAS
114 and SFAS 118 require loans to which they apply, to be measured at the
discounted amounts of their expected future cash flows using the loan's
effective interest rate or at the observable market price or the fair value of
the collateral for collateral dependent loans. The Statements are effective for
fiscal years beginning after December 15, 1994. The adoption of SFAS 114 and
SFAS 118 by the Bank during 1995 had no significant effect.

    Effective January 1, 1994, FNB adopted Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities." Accordingly, beginning on January 1, 1994, pursuant to FNB's
investment policy, certain securities are designated to be available for sale
and are reported at estimated fair value (based on quoted market prices). Net
unrealized gains and losses on such securities are not included in earnings, but
are reported, net of income taxes, as a separate component of stockholders'
equity. On January 1, 1994, FNB recorded a decrease of $291,222 in stockholders'
equity. At December 31, 1996 the stockholders' equity component for net
unrealized loss on securities available for sale was $223,683. The remaining
securities are deemed to be held to maturity, and are reported at amortized
cost. On December 31, 1996 net unrealized gains on securities held to maturity
were approximately $61,355. The $223,683 net decrease in stockholders' equity
discussed above and the $61,355 net unrealized appreciation of held to maturity
securities as of December 31, 1996 was largely attributable to changes in market
interest rates.

    FUNDING SOURCES AND LIQUIDITY MANAGEMENT

    FNB relies primarily on the Bank for its source of cash to pay its operating
expenses and to pay dividends. During 1995 and 1996, FNB paid annual dividends
at the rate of $8.00 per share, which aggregated to $239,624 per year. The cash
flow from the Bank to FNB comes in the form of dividends. At December 31, 1996,
FNB estimates that the Bank has excess accumulated earnings of approximately
$3,500,000 available for distribution, subject to regulatory approval and other
applicable requirements.

    The assets of the Bank are primarily funded through the use of borrowings in
the form of deposits. 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 primary sources of asset liquidity consist
of federal funds, maturing loans and investment securities.

    The Bank's funds management committee is charged with the responsibility of
maintaining an adequate level of liquidity and managing the risks associated
with interest rate changes while sustaining stable growth in net interest
income. The Bank's basic strategy is to minimize interest rate risk through
matching the repricing periods of earning assets and interest-bearing
liabilities.

    CAPITAL MANAGEMENT OF THE BANK

    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, 1995, 

                                       53
<PAGE>
 
all financial institutions are required to maintain a level of core capital
(known as Tier 1 capital) which must be at least 4.0% of risk-weighted assets,
and a minimum level of total capital of at least 8.0% 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 requirement and excess risk-based
capital at December 31, 1996 (dollars in thousands) are summarized as follow:

   (1)  Percentage based on risk-weighted assets of $61,922,000 at December 31, 
1996.

    As a supplement to the risk-based capital guidelines, the Federal Reserve
Board has also adopted a minimum ratio of Tier I capital to total average 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 4.0%. The actual Tier 1 leverage
ratio of the Bank was 15.78%, at December 31, 1996.

    INFLATION

    Management has considered the effects and potential effects of inflation on
its past and future operations and earnings performance. Inflation has not had
in recent years, nor is it expected to have in the foreseeable future, a
significant effect on the Company's operations or earnings performance.

                             CERTAIN REGULATORY AND OTHER
                         CONSIDERATIONS PERTAINING TO NORWEST

    Norwest and its banking subsidiaries are subject to extensive regulation by
federal and state agencies. The regulation of bank holding companies and their
subsidiaries is intended primarily for the protection of depositors, federal
deposit insurance funds and the banking system as a whole and is not in place to
protect stockholders or other investors.

    As discussed in more detail below, this regulatory environment, among other
things, may (a) restrict Norwest's ability to pay dividends on Norwest Common
Stock, (b) require Norwest to provide financial support to one or more of its
banking subsidiaries, (c) require Norwest and its banking subsidiaries to
maintain capital balances in excess of those desired by management, and/or (d)
require Norwest to pay higher deposit insurance premiums as a result of the
deterioration in the financial condition of depository institutions in general.

BANK REGULATORY AGENCIES

        Norwest Corporation, as a bank holding company, is subject to regulation
by the Federal Reserve Board under the Bank Holding Company Act.

        Norwest's national banking subsidiaries are regulated primarily by the
Office of the Comptroller of the Currency ("OCC"). Its state-chartered banking
subsidiaries are regulated primarily by the Federal Deposit Insurance
Corporation ("FDIC") and applicable state banking agencies. Its savings and loan
association subsidiary is regulated primarily by the Office of Thrift
Supervision ("OTS"). Norwest's federally insured banking subsidiaries and
savings and loan subsidiary are also subject to regulation by the FDIC.

        Norwest has other financial services subsidiaries that are subject to
regulation by the Federal Reserve Board and other applicable federal and state
agencies. For example, Norwest's brokerage subsidiary is subject to regulation
by the Securities and Exchange Commission, the National Association of
Securities Dealers, Inc. and state securities regulators. Norwest's insurance
subsidiaries are subject to regulation by applicable state insurance regulatory
agencies. Other nonbank subsidiaries of Norwest are subject to the laws and
regulations of both the federal government and the various states in which they
conduct business.

BANK HOLDING COMPANY ACTIVITIES; INTERSTATE BANKING

        A bank holding company is generally prohibited under the Bank Holding
Company Act from engaging in nonbanking (i.e., commercial or industrial)
activities, subject to certain exceptions. Specifically, the activities of a
bank holding company, and those companies that it controls or in which it holds
more than 5% of the voting stock, are limited to banking or managing or
controlling banks, furnishing services to its subsidiaries and such other
activities that the Federal Reserve Board determines to be so closely related to
banking as to be a "proper incident thereto." In determining whether an activity
is sufficiently related to banking, the Federal Reserve Board will consider
whether the performance of such activity by the bank holding company can
reasonably be expected to produce benefits to the public (e.g., greater
convenience, increased competition or gains in efficiency) that outweigh
possible adverse effects (e.g., undue concentration of resources, decreased or
unfair competition, conflicts of interest or unsound banking practices).

        Under the Reigle-Neal Interstate Banking and Branching Act of 1994 (the
"Interstate Banking Act"), which became effective on September 29, 1995, a bank
holding company may acquire banks in states other than its home state, subject
to any state requirement that the bank has been organized and operating for a
minimum period of time, not to exceed five years, and the requirement that the
bank holding company not control, prior to or following the proposed
acquisition, more than 10% of the total amount of deposits of insured 

                                       59
<PAGE>
 
depository institutions nationwide or, unless it is the bank holding company's
initial entry into the state, more than 30% of such deposits in the state (or
such lesser or greater amount set by the state).

        The Interstate Banking Act also authorizes banks to merge across state
lines (thereby creating interstate branches) effective June 1, 1997. States may
opt out of the Interstate Banking Act (thereby prohibiting interstate mergers in
the state) or opt in early (thereby allowing interstate mergers prior to June 1,
1997). Norwest will be unable to consolidate its banking operations in one state
with those of another state if either state in question has opted out of the
Interstate Banking Act. The state of Texas has opted out of the Interstate
Banking Act. The state of Montana has opted out until at least the year 2000.

        Norwest's acquisitions of banking institutions and other companies
generally are subject to the prior approval of the Federal Reserve Board and
other applicable federal or state regulatory authorities. In determining whether
to approve a proposed bank acquisition, federal banking regulators will
consider, among other factors, the effect of the acquisition on competition, the
public benefits expected to be received from the consummation of the
acquisition, the projected capital ratios and levels on a post-acquisition
basis, and the acquiring institution's record of addressing the credit needs of
the communities it serves, including the needs of low and moderate income
neighborhoods, consistent with the safe and sound operation of the bank, under
the Community Reinvestment Act of 1977, as amended.

DIVIDEND RESTRICTIONS

    Norwest is a legal entity separate and distinct from its banking and other
subsidiaries. Its principal source of funds to pay dividends on its common and
preferred stock and debt service on its debt is dividends from its subsidiaries.
Various federal and state statutes and regulations limit the amount of dividends
that may be paid to Norwest by its banking subsidiaries without regulatory
approval.

    Most of Norwest's banking subsidiaries are national banks. A national bank
must obtain the prior approval of the OCC to pay a dividend if the total of all
dividends declared by the bank in any calendar year would exceed the bank's net
income for that year combined with its retained net income for the preceding two
calendar years, less any required transfers to surplus or a fund for the
retirement of any preferred stock.

    The OTS imposes substantially similar restrictions on the payment of
dividends to Norwest by its savings and loan association subsidiary. Norwest's
state-chartered banking subsidiaries also are subject to dividend restrictions
under applicable state law.

        If, in the opinion of the applicable federal regulatory agency, a
depository institution 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), the regulator
may require, after notice and hearing, that such bank cease and desist from such
practice. The OCC has indicated that the payment of dividends would constitute
an unsafe and unsound practice if the payment would deplete a depository
institution's capital base to an inadequate level. Under the Federal Deposit
Insurance Act, an insured depository institution may not pay any dividend if the
institution is undercapitalized or if the payment of the dividend would cause
the institution to become undercapitalized. In addition, federal bank regulatory
agencies have issued policy statements which provide that depository
institutions and their holding companies should generally pay dividends only out
of current operating earnings.

        The ability of Norwest's banking subsidiaries to pay dividends to
Norwest may also be affected by various minimum capital requirements for banking
organizations, as described 

                                       60
<PAGE>
 
below. In addition, the right of Norwest to participate in the assets or
earnings of a subsidiary is subject to the prior claims of creditors of the
subsidiary.

HOLDING COMPANY STRUCTURE

        Transfer of Funds from Banking Subsidiaries. Norwest's banking
subsidiaries are subject to restrictions under federal law that limit the
transfer of funds or other items of value from such subsidiaries to Norwest and
its nonbanking subsidiaries (including Norwest, "affiliates") in so-called
"covered transactions." In general, covered transactions include loans and other
extensions of credit, investments and asset purchases, as well as other
transactions involving the transfer of value from a banking subsidiary to an
affiliate or for the benefit of an affiliate. Unless an exemption applies,
covered transactions by a banking subsidiary with a single affiliate are limited
to 10% of the banking subsidiary's capital and surplus and, with respect to all
affiliates in the aggregate, to 20% of the banking subsidiary's capital and
surplus. Also, loans and extensions of credit to affiliates generally are
required to be secured in specified amounts.

        Source of Strength Doctrine. The Federal Reserve Board has a policy that
a bank holding company is expected to act as a source of financial and
managerial strength to each of its subsidiary banks and, under appropriate
circumstances, to commit resources to support each such subsidiary bank. This
support may be required at times when the bank holding company may not have the
resources to provide it. Capital loans by a bank holding company to any of its
subsidiary banks are subordinate in right of payment to deposits and certain
other indebtedness of the subsidiary bank. In addition, 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.

        Depositor Preference. The Federal Deposit Insurance Act (the "FDI Act")
provides that, in the event of the "liquidation or other resolution" of an
insured depository institution, the claims of depositors of the institution
(including the claims of the FDIC as subrogee of insured depositors) and certain
claims for administrative expenses of the FDIC as a receiver will have priority
over other general unsecured claims against the institution. If an insured
depository institution fails, insured and uninsured depositors, along with the
FDIC, will have priority in payment ahead of unsecured, nondeposit creditors,
including the institution's parent holding company.

        Liability of Commonly Controlled Institutions. Under the FDI Act, an
insured depository institution is generally liable for any loss incurred, or
reasonably expected to be incurred, by the FDIC in connection with (a) the
default of a commonly controlled insured depository institution or (b) any
assistance provided by the FDIC to a commonly controlled 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.

REGULATORY CAPITAL STANDARDS AND RELATED MATTERS

        Risk-Based Capital. The Federal Reserve Board, the OCC and the FDIC have
adopted substantially similar risk-based and leverage capital guidelines for
banking organizations. The guidelines are intended to ensure that banking
organizations have adequate capital given the risk levels of their assets and
off-balance sheet commitments.

        The risk-based capital ratio is determined by classifying assets and
certain off-balance sheet financial instruments into weighted categories, with
higher levels of capital being required for those categories perceived as
representing greater risk. Under the capital guidelines, a banking
organization's total capital is divided into two tiers. "Tier 1 capital"

                                       61
<PAGE>
 
consists of common equity, retained earnings, qualifying noncumulative perpetual
preferred stock, a limited amount of qualifying cumulative perpetual preferred
stock and minority interests in the equity accounts of consolidated
subsidiaries, less certain items such as goodwill and certain other intangible
assets. "Tier 2 capital" consists of hybrid capital instruments, perpetual debt,
mandatory convertible debt securities, a limited amount of subordinated debt,
preferred stock that does not qualify as Tier 1 capital, and a limited amount of
the allowance for credit losses.

        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 currently 8%. The minimum Tier 1 capital to risk-adjusted assets is 4%. As of
December 31, 1996, Norwest's total capital and Tier 1 capital to risk-adjusted
assets ratios were 10.42% and 8.63%, respectively.

        The Federal Reserve Board also requires bank holding companies to comply
with minimum leverage ratio guidelines. The leverage ratio is the ratio of a
bank holding company's Tier 1 capital to its total consolidated quarterly
average assets, less goodwill and certain other intangible assets. The
guidelines require a minimum leverage ratio of 3% for bank holding companies
that meet certain specified criteria, including having the highest supervisory
rating. All other bank holding companies are required to maintain a minimum
leverage ratio of 4% to 5%. The Federal Reserve Board has not advised Norwest of
any specific leverage ratio applicable to it. As of December 31, 1996, Norwest's
leverage ratio was 6.15%.

        The Federal Reserve Board's capital guidelines provide that banking
organizations experiencing internal growth or making acquisitions are expected
to maintain strong capital positions substantially above the minimum supervisory
levels, without significant reliance on intangible assets. Also, the guidelines
indicate that the Federal Reserve Board will 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 (excluding intangibles) to total assets (excluding intangibles).

        Norwest's banking subsidiaries are subject to risk-based and leverage
capital guidelines substantially similar to those imposed by the Federal Reserve
Board on bank holding companies.

        Other Measures of Capital Adequacy and Safety and Soundness. In
assessing a banking organization's capital adequacy, federal bank regulatory
agencies will also consider the organization's credit concentration risk and
risks associated with nontraditional activities, as well as the organization's
ability to manage those risks. This evaluation will be performed as part of the
organization's regular safety and soundness examination.

        Effective January 1, 1998, federal bank regulatory agencies will require
banking organizations that engage in significant trading activity to calculate a
charge for market risk. Organizations may opt to comply effective January 1,
1997. Significant trading activity, for this purpose, means trading activity of
at least 10% of total assets or $1 billion, calculated on a consolidated basis
for bank holding companies. Federal bank regulators may apply the market risk
measure to other banks and bank holding companies if the agency deems necessary
or appropriate for safe and sound banking practices. Each agency may exclude
organizations that it supervises that otherwise meet the criteria under certain
circumstances. The market risk charge will be included in the calculation of an
organization's risk-based capital ratios. Norwest did not engage in significant
trading activity during the year ended December 31, 1996.

        As an additional means to identify problems in the financial management
of depository institutions, the FDI Act requires federal bank regulatory
agencies to establish certain non-capital safety and soundness standards for
institutions for which they are the primary 

                                       62
<PAGE>
 
federal regulator. The standards relate generally to operations and management,
asset quality, interest rate exposure and executive compensation. The agencies
are authorized to take action against institutions that fail to meet such
standards.

        Prompt Corrective Action. The FDI Act requires federal bank regulatory
agencies to take "prompt corrective action" with respect to FDIC-insured
depository institutions that do not meet minimum capital requirements. A
depository institution's treatment for purposes of the prompt corrective action
provisions will depend upon how its capital levels compare to various capital
measures and certain other factors, as established by regulation.

        Federal bank regulatory agencies have adopted regulations that classify
insured depository institutions into one of five capital-based categories. The
regulations use the total capital ratio, the Tier 1 capital ratio and the
leverage ratio as the relevant measures of capital. A depository institution is
(a) "well capitalized" if it has a risk-adjusted total capital ratio of at least
10%, a Tier 1 capital ratio of at least 6% and a leverage ratio of at least 5%
and is not subject to any order or written directive to maintain a specific
capital level; (b) "adequately capitalized" if it has a risk-adjusted total
capital ratio of at least 8%, a Tier 1 capital ratio of at least 4% and a
leverage ratio of at least 4% (3% in some cases) and is not well capitalized;
(c) "undercapitalized" if it has a risk-adjusted total capital ratio of less
than 8%, a Tier 1 capital ratio of less than 4% or a leverage ratio of less than
4% (3% in some cases); (d) "significantly undercapitalized" if it has a
risk-adjusted total capital ratio of less than 6%, a Tier 1 capital ratio of
less than 3% or a leverage ratio of less than 3%; and (e) "critically
undercapitalized" if its tangible equity is less than 2% of total assets. As of
December 31, 1996, all of Norwest's insured depository institutions met the
criteria for well capitalized institutions as set forth above.

        A depository institution's primary federal bank regulator is authorized
to downgrade the institution's capital category to the next lower category upon
a determination that the institution is engaged in an unsafe or unsound
condition or is engaged in an unsafe or unsound practice. An unsafe or unsound
practice can include receipt by the institution of a less than satisfactory
rating on its most recent examination with respect to its asset quality,
management, earnings or liquidity.

        The FDI Act 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 as a result be
undercapitalized. Undercapitalized depository institutions are subject to a wide
range of limitations on operations and activities (including asset growth) 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 the plan. The aggregate
liability of the parent holding company is limited to the lesser of (a) 5% of
the depository institution's total assets at the time it became undercapitalized
or (b) the amount which is necessary (or would have been necessary) to bring the
institution into compliance with all capital standards applicable with respect
to the institution as of the time it fails to comply with the plan. If an
undercapitalized 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.

FDIC INSURANCE

        The FDIC insures the deposits of Norwest's depository institution
subsidiaries through the Bank Insurance Fund (BIF) or, in the case of deposits
held by its savings and loan association subsidiary or deposits held by banking
subsidiaries as a result of savings and loan associations acquired by Norwest,
through the Savings Association Insurance Fund (SAIF). The amount of FDIC
assessments paid by each BIF member institution is based on its relative risk of
default as measured by regulatory capital ratios and other factors.
Specifically, the assessment rate is based on the institution's capitalization
risk category and supervisory subgroup category. An institution's capitalization
risk category is based on the FDIC's determination of whether the institution is
well capitalized, adequately capitalized or less than adequately capitalized. An
institution's supervisory subgroup category is based on the FDIC's assessment of
the financial condition of the institution and the probability that FDIC
intervention or other corrective action will be required. 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.

        The BIF assessment rate currently ranges from zero to 27 cents per $100
of domestic deposits, with Subgroup A institutions assessed at a rate of zero
and Subgroup C institutions assessed at a rate of 27 cents. The FDIC may
increase or decrease the assessment rate schedule on a semiannual basis. An
increase in the rate assessed one or more of Norwest's banking subsidiaries
could have a material adverse effect on Norwest's earnings, depending on the
amount of the increase. The FDIC is authorized to terminate a depository
institution's deposit insurance upon a finding by the FDIC that the
institution's financial condition is unsafe or unsound or that the institution
has engaged in unsafe or unsound practices or has violated any applicable rule,
regulation, order or condition enacted or imposed by the institution's
regulatory agency. The termination of deposit insurance with respect to one or
more of Norwest's subsidiary depository institutions could have a material
adverse effect on Norwest's earnings, depending on the collective size of the
particular institutions involved.

        Deposits insured by SAIF are currently assessed at the BIF rate of zero
to 27 cents per $100 of domestic deposits. The SAIF assessment rate may increase
or decrease as is necessary to maintain the designated SAIF reserve ratio of
1.25% of insured deposits.

        Effective January 1, 1997, all FDIC-insured depository institutions must
pay an annual assessment to provide funds for the payment of interest on bonds
issued by the Financing Corporation, a federal corporation chartered under the
authority of the Federal Housing Finance Board. The bonds (commonly referred to
as FICO bonds) were issued to capitalize the Federal Savings and Loan Insurance
Corporation. Until December 31, 1999 or when the last savings and loan
association ceases to exist, whichever occurs first, depository institutions
will pay approximately 6.4 cents per $100 of SAIF-assessable deposits and
approximately 1.3 cents per $100 of BIF-assessable deposits.

        Subject to certain conditions, BIF and SAIF will be merged into one
insurance fund effective January 1, 1999.

FISCAL AND MONETARY POLICIES

        Norwest's business and earnings are affected significantly by the fiscal
and monetary policies of the federal government and its agencies. Norwest is
particularly affected by the policies of the Federal Reserve Board, which
regulates the supply of money and credit in the United States. Among the
instruments of monetary policy available to the Federal Reserve are (a)
conducting open market operations in United States government securities, 

                                       64
<PAGE>
 
(b) changing the discount rates of borrowings of depository institutions, 
(c) imposing or changing reserve requirements against depository institutions'
deposits, and (d) imposing or changing reserve requirements against certain
borrowing by banks and their affiliates. These methods are used in varying
degrees and combinations to directly affect the availability of bank loans and
deposits, as well as the interest rates charged on loans and paid on deposits.
For that reason alone, the policies of the Federal Reserve Board have a material
effect on the earnings of Norwest's banking subsidiaries and, thus, those of
Norwest.

COMPETITION

        The financial services industry is highly competitive. Norwest's
subsidiaries compete with traditional financial services providers, such as
banks, savings and loan associations, credit unions, finance companies, mortgage
banking companies, insurance companies, and money market and mutual fund
companies. They also face increased competition from non-banking institutions
such as brokerage houses and insurance companies, as well as from financial
services subsidiaries of commercial and manufacturing companies. Many of these
competitors enjoy the benefits of advanced technology, fewer regulatory
constraints and lower cost structures.

        The financial services industry is likely to become even more
competitive as further technological advances enable more companies to provide
financial services. These technological advances may diminish the importance of
depository institutions and other financial intermediaries in the transfer of
funds between parties.

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



      Board of Directors
      The First National Bankshares, Inc. and Subsidiaries

      We have audited the accompanying consolidated balance sheet of The First
      National Bankshares, Inc. and Subsidiaries as of December 31, 1996, and
      the related consolidated statements of earnings and retained earnings and
      cash flows for the year then ended. These consolidated financial
      statements are the responsibility of the company's management. Our
      responsibility is to express an opinion on these consolidated financial
      statements based on our audit.

      We conducted our audit 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 audit
      provides a reasonable basis for our opinion.

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

                          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                      December 31, 1996

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    A summary of the corporation's significant accounting policies applied in
    the preparation of the accompanying financial statements follows.

    1.  Operations

    The First National Bankshares, Inc. (the corporation) is a bank holding
    company which was organized in 1988, and at that time acquired 100%
    ownership of The First National Bank of Tucumcari, Tucumcari, New Mexico,
    and the First National Bank of Santa Rosa, Santa Rosa, New Mexico. In
    September 1991, The First Security Trust Company, a wholly owned subsidiary,
    was formed. On January 1, 1993, The First National Bank of Tucumcari and the
    First National Bank of Santa Rosa were merged, resulting in the Santa Rosa
    bank becoming a branch of The First National Bank of Tucumcari. The
    corporation opened a branch bank in Las Vegas, New Mexico in 1996. The First
    Security Trust Company was closed during 1996.

    The corporation provides retail, commercial, and corporate banking services.

    2.  Consolidation

    The consolidated financial statements include the accounts of the
    corporation and its subsidiaries, The First National Bank of Tucumcari and
    The First Security Trust Company. Significant intercompany accounts and
    transactions have been eliminated.

    3.  Cash and cash equivalents

    For purposes of the consolidated statement of cash flows, the corporation
    considers cash and due from banks, interest-bearing deposits with banks and
    federal funds sold to be cash equivalents.

    4.  Securities

    Investment securities which the corporation intends to hold until maturity
    are stated at cost, adjusted for amortization of premiums and accretion of
    discounts using a method that approximates level yield. Investments which
    the corporation intends to hold for indefinite periods of time, including
    securities that management intends to use as part of its asset/liability
    management strategy, or that may be sold in response to changes in interest
    rates, changes in prepayment risk, the need to increase regulatory capital
    or similar factors, are classified as available for sale.

                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

                                      December 31, 1996

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

    Effective January 1, 1994, the corporation adopted Statement of Financial
    Accounting Standards ("SFAS") No. 115, "Accounting for Certain Investments
    in Debt and Equity Securities" (SFAS 115). Accordingly, investment
    securities available for sale are measured at fair value. Net unrealized
    gains and losses, net of deferred taxes, on investment securities available
    for sale are excluded from earnings and reported as a separate component of
    stockholders' equity until realized. The classification of securities is
    determined at the date of purchase and subsequent transfers, if any, between
    security classifications are recorded at fair value.

    Realized gains and losses on sales of securities are computed by the
    specific identification method at the time of disposition and are recorded
    in non-interest income.

    Trading account securities are purchased with the intent to earn a profit by
    trading or selling the securities. These securities are stated at fair
    value. Adjustments to the fair value are reported in other non-interest
    income. The corporation has no securities classified as trading account
    securities.

    5.  Loans

    Loans are stated at their principal amount. Interest income is recognized on
    an accrual basis except when a loan is past due and is placed on non-accrual
    status by the loan committee. When a loan is placed on non-accrual status,
    uncollected interest accrued in prior years is charged against the allowance
    for credit losses. Interest income is subsequently recognized only to the
    extent cash payments are received. A loan is returned to accrual status when
    principal and interest are no longer past due and collectibility is no
    longer doubtful.

    Restructured loans are those on which concessions in principal amount or
    interest rate terms have been made as a result of deterioration in a
    borrower's financial condition.

    Interest on these loans is accrued at the new terms.

    Unearned discount on consumer loans is recognized by the interest method or
    other methods for which results are not materially different from the
    interest method. Loan origination fees and certain direct origination costs,
    where material, are capitalized and recognized as an adjustment of the yield
    of the related loan.

                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

                                      December 31, 1996

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

    Effective January 1, 1995, the corporation adopted Statement of Financial
    Accounting Standards No. 114, "Accounting by Creditors for Impairment of a
    Loan" and Statement of Financial Accounting Standards No. 118, "Accounting
    by Creditors for Impairment of a Loan - - Income Recognition and
    Disclosures". Under the corporation's credit policies and practices, all
    non-accrual and restructured commercial, agricultural, construction, and
    commercial real estate loans meet the definition of impaired loans under
    SFAS 114 and 118. For purposes of this definition, certain loans where only
    the principal repayment time-schedule terms have been modified are not
    considered restructured, and therefore not considered impaired. Impaired
    loans as defined by SFAS 114 and 118 exclude certain consumer and
    residential real estate loans. Loan impairment is measured based on the
    present value of expected future cash flows discounted at the loan's
    effective interest rate or, as a practical expedient, at the observable
    market price of the loan or the fair value of the collateral if the loan is
    collateral dependent. The adoption of SFAS 114 and 118 did not affect the
    corporation's financial position or results of operation.

    6.  Allowance for Credit Losses

    The allowance for credit losses is based upon management's evaluation of a
    number of factors, including credit loss experience, risk analyses of loan
    portfolios, as well as current and expected economic conditions. It is
    reasonably possible that economic or other factors could deteriorate at any
    time in the future, causing a change in management's estimate of the
    allowance for credit losses that would be material to the financial
    statements.

    Charge-offs are loans or portions thereof evaluated as uncollectible. Other
    consumer loans are charged off when certain delinquency criteria are met,
    unless fully secured.

    7.  Premises and equipment

    Premises and equipment are stated at cost, less accumulated depreciation and
    amortization. Owned properties and equipment are depreciated on a
    straight-line basis over their estimated useful lives.

    The costs of improvements are capitalized. Maintenance and repairs, as well
    as gains and losses on dispositions of premises and equipment, are included
    in non-interest expenses.

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

    8.  Other Real Estate Owned

    Other real estate owned is stated at the lower of cost or appraised value.
    When a property is acquired, the excess of the recorded investment in the
    property over fair value, if any, is charged to the allowance for credit
    losses. Subsequent declines in the estimated fair value, net operating
    results, and gains or losses on disposition of the property are included in
    other non-interest expenses.

    9.  Income Taxes

    The corporation and its subsidiaries file consolidated federal and state
    income tax returns. The effects of current or deferred taxes are recognized
    as a current and deferred tax liability or asset based on current tax laws.
    Accordingly, income tax expense in the consolidated statements of income
    includes charges or credits to properly reflect the current and deferred tax
    asset or liability.

    10. Management Estimates

    In preparing financial statements in conformity with generally accepted
    accounting principles, management makes estimates and assumptions that
    affect the reported amounts of assets and liabilities and disclosures of
    contingent assets and liabilities at the date of the financial statements,
    as well as the reported amounts of revenues and expenses during the
    reporting period. Actual results could differ from those estimates.

NOTE F - EMPLOYEE BENEFIT PLAN

    RETIREMENT PLANS

    The corporation's noncontributory defined benefit retirement plan covers all
    full-time employees, age 21 and older, who complete one year of service.
    Pension benefits provided are based on the employee's highest compensation
    in three consecutive years during the last ten years of employment. The
    corporation's funding policy is to maintain adequate assets to provide for
    both benefits earned to date and those expected to be earned in the future.

    The plan's funded status at December 31, 1996, is presented below:

        Actuarial present value of benefit obligations:

    The discount rate and rate of increase in future compensation levels used in
    determining the actuarial present value of the projected benefit obligation
    was 7.25% and 4.5% respectively. The expected long-term rate of returns on
    assets was 8.25%. It is management's policy to fund accrued pension
    liabilities annually.

    OTHER POST-RETIREMENT BENEFITS

    In October 1985, the corporation entered into salary continuation agreements
    with nine employees to pay monthly retirement benefits for ten years. The
    agreements, which have been settled with the employees, will require the
    corporation to pay approximately $373,000 to terminate the retirement
    benefits. In addition, a healthcare and retirement benefit agreement was
    entered into on February 2, 1995, which requires the company to pay
    healthcare and retirement benefits to a former employee. The retirement
    payments are $1,500 per month through April 1999 and $460 per month from May
    1999 through February 2004. The healthcare benefits, which are estimated at
    $460 per month, must be provided until the former employee's spouse reaches
    age 65, which will occur in 1998. The liability for these retirement
    benefits, present value calculated at December 31, 1996, using an 8% rate of
    return, is included as accrued expenses on the accompanying balance sheet.
    Expense related to change in the present value calculation totaled $10,587
    during the year ended December 31, 1996. These benefits are anticipated to
    be funded out of current operations when paid.

NOTE G - INCOME TAXES - CONTINUED

    The corporation has determined that it is not required to establish a
    valuation reserve for the deferred tax asset since it is more likely than
    not that the deferred tax asset of $80,000 will be principally realized
    through future reversals of existing taxable temporary differences, and, to
    a lesser extent, future taxable income.

    The deferred tax asset/liability related to SFAS 115 had no impact on 1995
    or 1994 income tax expense as the effect of unrealized gains and losses, net
    of taxes, was recorded in stockholders' equity.

    The current income tax provision reconciled to the tax computed at the
    statutory Federal rate was:

NOTE H - COMMITMENTS AND CONTINGENT LIABILITIES

    At December 31, 1996, the corporation and its subsidiary, the First National
    Bank of Tucumcari, were obligated under a noncancelable lease for premises
    in Las Vegas, New Mexico, with an initial term of five years with two
    options for five year extensions. The initial lease term expires in 2001.
    The renewal periods provide for increased rentals. Rental expense amounted
    to $10,325 in 1996. Future minimum rental payments under this lease at
    December 31, 1996, were:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

                               December 31, 1996

NOTE H - COMMITMENTS AND CONTINGENT LIABILITIES - CONTINUED

    To meet the financing needs of its customers and as part of its overall risk
    management strategy, (not for trading purposes), the corporation is a party
    to financial instruments with off-balance sheet risk. These financial
    instruments include commitments to extend credit, unused lines of credit and
    letters of credit. Such financial instruments are recorded in the financial
    statements when they are funded or related funds are received.

    The corporation's exposure to credit loss in the event of nonperformance by
    the other party to the financial instrument for commitments to extend credit
    and standby letters of credit is represented by the contractual amount of
    those instruments. A summary of the approximate contractual amounts of these
    financial instruments as of December 31, 1996, follows:

         Commitments to extend credit                       $  1,650,000
                                                              ==========

         Letters of credit                                  $     75,000
                                                             ===========

         Unused lines of credit                             $  4,200,000
                                                              ==========

    Commitments to extend credit generally have fixed expiration dates or other
    termination clauses. Since many of the commitments are expected to expire
    without being drawn upon, the total commitment amounts do not necessarily
    represent future cash requirements. The amount of collateral obtained is
    based on management's credit evaluation of the counterparty. Collateral held
    varies, but may include cash, marketable securities, accounts receivable,
    inventory, property, plant and equipment, and income-producing commercial
    properties.

NOTE I - SIGNIFICANT GROUP CONCENTRATIONS OF CREDIT RISK

    Most of the corporation's business activity is with customers located in
    eastern New Mexico. As of December 31, 1996, the corporation was creditor
    for approximately $11 million of farm and ranch loans, repayment of which is
    dependent in large part on the price of livestock, which may vary
    significantly from year to year. These agricultural loans are generally
    secured by livestock, equipment and, whenever possible, real estate. The
    loans are expected to be repaid from cash flow of the debtors operations.
    During 1996, the cattle market suffered a decline in prices. Despite the
    decline in cattle prices, credit losses from lending in this volatile
    industry compare favorably with the corporation's loan portfolio as a whole.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONCLUDED

                               December 31, 1996

NOTE J - REGULATORY MATTERS

    The corporation is subject to various regulatory capital requirements
    administered by the federal banking agencies. Failure to meet minimum
    capital requirements can initiate certain mandatory - and possibly
    additional discretionary - actions by regulators that, if undertaken, could
    have a direct material effect on the corporation's financial statements.
    Under capital adequacy guidelines and the regulatory framework for prompt
    corrective action, the corporation must meet specific capital guidelines
    that involve quantitative measures of the corporation's assets, liabilities,
    and certain off-balance-sheet items as calculated under regulatory
    accounting practices. The corporation's capital amounts and classification
    are also subject to qualitative judgments by the regulators about
    components, risk weightings, and other factors.

    Quantitative measures established by regulation to ensure capital adequacy
    require the corporation to maintain minimum amounts and ratios of total and
    Tier I capital to risk-weighted assets, and of Tier I capital to average
    assets. Management believes, as of December 31, 1996, that the corporation
    meets all capital adequacy requirements to which it is subject.

    As of December 31, 1996, the most recent notification from the Office of the
    Comptroller of the Currency categorized the corporation as well capitalized
    under the regulatory framework for prompt corrective action. To be
    categorized as well capitalized the corporation must maintain minimum total
    risk-based, Tier I risk-based, and Tier I leverage ratios. There are no
    conditions or events since that notification that management believes have
    changed the corporation's category. As of December 31, 1996, the
    corporation's total capital to risk-weighted assets ratio was 15.8% when the
    requirements to be well capitalized under prompt corrective action
    provisions was 10.0%. Tier I capital to risk-weighted assets was 14.9% when
    the requirement to be well capitalized was 6.0%

NOTE K - SUBSEQUENT EVENT

    On January 16, 1997, the corporation's board of directors approved a merger
    agreement with Norwest Corporation wherein the corporation will become a
    wholly-owned subsidiary of Norwest. The transaction is an all stock exchange
    and is expected to be accounted for using the purchase method of accounting.
    The merger must be approved by the corporation's stockholders and by
    regulatory agencies and is expected to be completed during 1997.

                             PLAN OF REORGANIZATION

        AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") entered into as
of the 17th day of January, 1997, by and between THE FIRST NATIONAL BANKSHARES,
INC. ("FNBI"), a New Mexico corporation, and NORWEST CORPORATION ("Norwest"), a
Delaware corporation.

        WHEREAS, the parties hereto desire to effect a reorganization whereby a
wholly-owned subsidiary of Norwest will merge with and into FNBI (the "Merger")
pursuant to a plan of merger (the "Merger 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 FNBI of the par value
of $1.00 per share ("FNBI Common Stock") outstanding immediately prior to the
time the Merger becomes effective in accordance with the provisions of the
Merger Agreement 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) Merger. Subject to the terms and conditions contained herein, a
            ------
wholly-owned subsidiary of Norwest ("Merger Co.") will be merged by statutory
merger with and into FNBI pursuant to the Merger Agreement, with FNBI as the
surviving corporation, in which merger each share of FNBI Common Stock
outstanding immediately prior to the Effective Time of the Merger (as defined
below) (other than shares as to which statutory dissenters' appraisal rights
have been exercised) will be converted into and exchanged for the number of
shares of Norwest Common Stock determined by dividing the Adjusted Norwest
Shares (as defined below) by the number of shares of FNBI Common Stock then
outstanding. The "Adjusted Norwest Shares" shall mean the following:

        (i)    If 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 20 trading days ending on the day
               immediately preceding the meeting of the shareholders of FNBI
               held to vote on this Agreement and the Merger Agreement (the
               "Norwest Measurement Price") is equal to or greater than $40.25,
               the Adjusted Norwest Shares shall be 304,472.

        (ii)   If the Norwest Measurement Price is equal to or less than $36.25,
               the Adjusted Norwest Shares shall be 338,069.

        (iii)  If the Norwest Measurement Price is less than $40.25 but more
               than $36.25, the Adjusted Norwest Shares shall be the number
               determined by dividing $12,255,000 by the Norwest Measurement
               Price.

        (b) Norwest Common Stock Adjustments. If, between the date hereof and
            --------------------------------
the Effective Time of the Merger (as defined in subparagraph (d) below), 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, readjustment, or similar transaction,
or if a stock dividend thereon shall be declared with a record date within such
period (a "Common Stock Adjustment"), then the number of 

                                      A-1
<PAGE>
 
shares of Norwest Common Stock into which a share of FNBI Common Stock shall be
converted pursuant to subparagraph (a) above and/or the price of such shares for
the purposes of calculating the Norwest Measurement Price will be appropriately
and proportionately adjusted so that the number of such shares of Norwest Common
Stock into which a share of FNBI Common Stock shall be converted will equal the
number of shares of Norwest Common Stock which the holder of a share of FNBI
Common Stock would have received pursuant to such reclassification,
recapitalization, split-up, combination, exchange of shares, readjustment or
similar transaction or stock dividend, had the record date therefor been
immediately following the Effective Time of the Merger (as defined in
subparagraph (d) below).

        (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 Date of the Merger (as defined in subparagraph (d) below).

        2. Representations and Warranties of FNBI. FNBI represents and warrants
to Norwest as follows:

        (a) Organization and Authority. FNBI is a corporation duly organized,
            --------------------------
validly existing and in good standing under the laws of the State of New Mexico,
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 FNBI and the FNBI Subsidiaries (as defined in
paragraph 2(b) below) 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. FNBI is registered as a bank holding company with the Federal Reserve
Board under the Bank Holding Company Act of 1956, as amended (the "BHC Act").

incorporation and bylaws, as amended.

                                      A-2
<PAGE>
 
        (b) FNBI's Subsidiaries. Schedule 2(b) sets forth a complete and correct
            -------------------
list of all of FNBI's subsidiaries as of the date hereof (individually an "FNBI
Subsidiary" and collectively the "FNBI 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 FNBI. No equity security of any FNBI
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 FNBI 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. ss. 55 (1982), all
of such shares so owned by FNBI are fully paid and nonassessable and, except as
set forth on Schedule 2(b), are owned by it free and clear of any lien, claim,
charge, option, encumbrance or agreement with respect thereto. Each FNBI
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), FNBI 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.

        (c) Capitalization. The authorized capital stock of FNBI consists of
            --------------
100,000 shares of common stock, $1.00 par value, of which as of the close of
business on September 30, 1996, 29,953 shares were outstanding and no shares
were held in the treasury. The maximum number of shares of FNBI Common Stock
(assuming for this purpose that phantom shares and other share-equivalents,
constitute FNBI Common Stock) that would be outstanding as of the Effective Date
of the Merger if all options, warrants, conversion rights and other rights with
respect thereto were exercised is 29,953. All of the outstanding shares of
capital stock of FNBI 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 FNBI or any FNBI Subsidiary to issue, sell or
otherwise dispose of, or to purchase, redeem or otherwise acquire, any shares of
capital stock of FNBI or any FNBI Subsidiary. Since September 30, 1996, no
shares of FNBI capital stock have been issued, purchased, redeemed or otherwise
acquired, directly or indirectly, by FNBI or any FNBI Subsidiary and, except as
set forth on Schedule 2(c), no dividends or other distributions have been
declared, set aside, made or paid to the shareholders of FNBI.

        (d) Authorization. FNBI has the corporate power and authority to enter
            -------------
into this Agreement and the Merger 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
Merger Agreement by FNBI and the consummation of the transactions contemplated
hereby and thereby have been duly authorized by the Board of Directors of FNBI.
Subject to such approvals of shareholders and of government agencies and other
governing boards having regulatory authority over FNBI as may be required by
statute or regulation, this Agreement and the Merger Agreement are valid and
binding obligations of FNBI enforceable against FNBI in accordance with their
respective terms.

        Except as set forth on Schedule 2(d), neither the execution, delivery
and performance by FNBI of this Agreement or the Merger Agreement, nor the
consummation of the transactions contemplated hereby and thereby, nor compliance
by FNBI 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 

                                      A-3
<PAGE>
 
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 FNBI or any FNBI 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 FNBI or any
FNBI Subsidiary is a party or by which it may be bound, or to which FNBI or any
FNBI Subsidiary or any of the properties or assets of FNBI or any FNBI
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 FNBI,
violate any judgment, ruling, order, writ, injunction, decree, statute, rule or
regulation applicable to FNBI or any FNBI 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 (the "HSR Act"), and filings required to effect the Merger under New
Mexico law, 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 FNBI of the transactions contemplated by this Agreement and the
Merger Agreement.

        (e) FNBI Financial Statements. The unaudited balance sheets of FNBI and
            -------------------------
FNBI's Subsidiaries as of December 31, 1995 and 1994 and related consolidated
statements of operations, changes in stockholders' equity and cash flows for the
two years ended December 31, 1995, and the unaudited consolidated balance sheets
of FNBI and FNBI's Subsidiaries as of September 30, 1996, and the related
unaudited consolidated statements of operations, changes in stockholders' equity
and cash flows for the nine months then ended (collectively, the "FNBI Financial
Statements"), have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis and present fairly (subject
to normal recurring adjustments) the consolidated financial position of FNBI and
FNBI's Subsidiaries at the dates and the consolidated results of operations and
cash flows of FNBI and FNBI's Subsidiaries for the periods stated therein.

        (f) Reports. Since December 31, 1990, each of FNBI and the FNBI
            -------
Subsidiaries 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 "FNBI Reports". As of their respective
dates, the FNBI Reports complied in all material respects with all the rules and
regulations promulgated by the 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 FNBI Reports have been made available to
Norwest by FNBI. FNBI is not required to file reports with the Securities and
Exchange Commission (the "SEC") pursuant to either Section 12 or Section 15(d)
of the Exchange Act.

        (g) Properties and Leases. Except as may be reflected in the FNBI
            ---------------------
Financial Statements, and except for any lien for current taxes not yet
delinquent, FNBI and each FNBI 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 FNBI's consolidated balance
sheet as of September 30, 1996, and to all real and personal property acquired
since such date, except such real and personal property as has been 

                                      A-4
<PAGE>
 
disposed of in the ordinary course of business. All leases of real property
pursuant to which FNBI or any FNBI Subsidiary, as lessee, leases real 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 FNBI or such FNBI Subsidiary or any event
which, with notice or lapse of time or both, would constitute such a material
default. Substantially all FNBI's and each FNBI 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 FNBI and the FNBI Subsidiaries has filed all federal,
            -----
state, county, local and foreign tax returns, including information returns,
required to be filed by it and has paid 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 FNBI and the FNBI Subsidiaries for
the fiscal year ended December 31, 1992, 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 as set forth on Schedule 2(h), (i) neither
FNBI nor any FNBI Subsidiary is a party to any pending action or proceeding, nor
to the best knowledge of FNBI is any such action or proceeding threatened by any
governmental authority, for the assessment or collection of taxes, interest,
penalties, assessments or deficiencies 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 FNBI or any FNBI
Subsidiary which has not been settled, resolved and fully satisfied. Each of
FNBI and the FNBI 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 September 30, 1996, 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 FNBI and the FNBI Subsidiaries with respect to
all periods through the date thereof.

        (i) Absence of Certain Changes. Since September 30, 1996, there has been
            --------------------------
no change in the business, financial condition or results of operations of FNBI
or any FNBI 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 FNBI and the FNBI Subsidiaries taken as a whole.

        (j) Commitments and Contracts. Except as set forth on Schedule 2(j),
            -------------------------
neither FNBI nor any FNBI Subsidiary is a party or subject to any of the
following (whether written or oral, express or implied):

               (i) any employment contract or understanding pursuant to which
        FNBI or any FNBI Subsidiary has any current or future obligation or
        liability (including any understandings or obligations with respect to
        severance pay, termination pay or fringe benefits), other than solely an
        obligation of confidentiality, with any present or former officer,
        director, employee or consultant (other than those which are terminable
        at will by FNBI or such FNBI 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;

                                      A-5
<PAGE>
 
               (iv) any contract containing covenants which (a) limit the
        ability of FNBI or any FNBI Subsidiary to compete in any line of
        business or with any person, (b) involve any restriction of the
        geographical area in which, or method by which, FNBI or any FNBI
        Subsidiary may carry on its business (other than as may be required by
        law or applicable regulatory authorities), or (c) require FNBI or any
        FNBI Subsidiary to deal exclusively with any vendor, service provider or
        other third party;

               (v) any other contract or agreement which is a "material
        contract" within the meaning of Item 601(b)(10) of Regulation S-K;

               (vi) any lease of personal property with annual rental payments
        aggregating $10,000 or more;

               (vii) any other contract or agreement that has a term of one year
        or more and annual payments of $25,000 or more;

               (viii) any agreement or commitment with respect to the Community
        Reinvestment Act with any state or federal bank regulatory authority or
        any other party; or

               (ix) any current or past agreement, contract or understanding
        with any current or former director, officer, employee, consultant,
        financial adviser, broker, dealer, or agent providing for any rights of
        indemnification in favor of such person or entity.

        (k) Litigation and Other Proceedings. In connection with the preparation
            --------------------------------
of its unaudited financial statements for the year ended December 31, 1995, FNBI
did not request from legal counsel letters with respect to contingencies.
Schedule 2(k) contains a list of all legal and regulatory proceedings pending
against FNBI or any FNBI Subsidiary as of the date hereof. Neither FNBI nor any
FNBI Subsidiary is a party to any pending or, to the best knowledge of FNBI,
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 FNBI and the FNBI
Subsidiaries taken as a whole.

        (l) Insurance. Each of FNBI and the FNBI Subsidiaries is presently
            ---------
insured, and during each of the past five calendar years (or during such lesser
period of time as FNBI has owned such FNBI Subsidiary) has been insured, for
reasonable amounts with insurance companies that, to the best knowledge of FNBI,
are financially sound and reputable 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. FNBI has delivered to Norwest correct and complete copies of all
material policies of insurance of FNBI and the FNBI Subsidiaries currently in
effect.

        (m) Compliance with Laws. Each of FNBI and the FNBI Subsidiaries 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 FNBI or such FNBI Subsidiary;
all such permits, licenses, certificates of authority, orders and approvals are
in full force and effect and, to the best knowledge of FNBI, no suspension or
cancellation of any of them is threatened; and all such filings, applications
and registrations are current. The conduct by each of FNBI and the FNBI
Subsidiaries 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, 

                                      A-6
<PAGE>
 
license or regulation, other than laws, statutes, ordinances, licenses or
regulations relating to environmental liability, as to which FNBI makes only the
representations and warranties set forth in paragraph 2(v) herein. Neither FNBI
nor any FNBI 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 which reasonably
could be expected to have a material adverse effect on the business or
properties of FNBI and the FNBI Subsidiaries taken as a whole. Except for
statutory or regulatory restrictions of general application and except as set
forth on Schedule 2(m), no federal, state, municipal or other governmental
authority has placed any restriction on the business or properties of FNBI or
any FNBI Subsidiary which reasonably could be expected to have a material
adverse effect on the business or properties of FNBI and the FNBI Subsidiaries
taken as a whole.

        (n) Labor. No work stoppage involving FNBI or any FNBI Subsidiary is
            -----
pending or, to the best knowledge of FNBI, threatened. Neither FNBI nor any FNBI
Subsidiary is involved in, or to the best knowledge of FNBI threatened with or
affected by, any labor dispute, arbitration, lawsuit or administrative
proceeding which could materially and adversely affect the business of FNBI or
such FNBI Subsidiary.

        (o) Material Interests of Certain Persons. Except as set forth on
            -------------------------------------
Schedule 2(o), to the best knowledge of FNBI no officer or director of FNBI or
any FNBI Subsidiary, or any "associate" (as such term is defined in Rule l4a-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 FNBI or any FNBI Subsidiary.

        Schedule 2(o) sets forth a correct and complete list of any loan or
other extension of credit from FNBI or any FNBI 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 FNBI's or such FNBI Subsidiary's Board of Directors.

        (p)  FNBI 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 FNBI or any FNBI Subsidiary 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 FNBI or any FNBI Subsidiary, are those set forth on Schedule 2(p)(i)
        (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)(ii), FNBI or the FNBI Subsidiaries
        have received favorable determination letters from the Internal Revenue
        Service under the provisions of the Tax Reform Act of 1986 ("TRA `86")
        for each of the Plans to which the qualification requirements of Section
        401(a) of the Internal Revenue Code of 1986, as amended (the "Code"),
        apply. FNBI knows of no reason that any Plan 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 knows
        of no reason that each related trust is not exempt from taxation under
        Section 501(a) of the Code.

               (iii) The present value of all benefits vested and all benefits
        accrued under each 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 

                                      A-7
<PAGE>
 
        such Plan as of the end of the most recent Plan year, exceed the value
        of the assets of the Plan allocable to such vested or accrued benefits.

               (iv) Except as disclosed in Schedule 2(p)(iv), and to the best
        knowledge of FNBI, no Plan or any trust created thereunder or 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 has violated any of the fiduciary
        standards under Part 4 of Title I of ERISA, which could subject, to the
        best knowledge of FNBI or any FNBI Subsidiary, such Plan or trust, or
        any trustee, fiduciary or administrator thereof, or any party dealing
        with any such Plan or trust, to the tax or penalty on prohibited
        transactions imposed by said Section 4975 or would result in material
        liability to FNBI and the FNBI Subsidiaries taken as a whole.

               (v) No Plan 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 Plan, other than those events which may result from the
        transactions contemplated by this Agreement and the Merger Agreement.

               (vi) No 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), during the last five Plan years
        which would result in a material liability.

               (vii) Except as disclosed in Schedule 2(p)(vii), neither the
        execution and delivery of this Agreement and the Merger 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 FNBI or
        any FNBI 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 FNBI and the
            --------------------
FNBI Subsidiaries supplied or to be supplied by FNBI 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 FNBI Common Stock pursuant to the provisions of the Merger Agreement
(the "Registration Statement"), (ii) the proxy statement to be mailed to FNBI's
shareholders in connection with the meeting to be called to consider the Merger
(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 Merger 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, and, in the case of the Proxy Statement as amended or
supplemented at the time of the meeting of shareholders referred to in paragraph
4(c), contain an untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. All documents FNBI and
the FNBI Subsidiaries are responsible for filing with the SEC and with any other
regulatory authority in connection with the Merger will comply as to form in all
material respects with the provisions of applicable law.

        (r) Registration Obligations. Except as set forth on Schedule 2(r),
            ------------------------
neither FNBI nor any FNBI Subsidiary is under any obligation, contingent or
otherwise, which will survive the 

                                      A-8
<PAGE>
 
Merger, by reason of any agreement to register any of its securities under the
Securities Act.

        (s) Brokers and Finders. Neither FNBI nor any FNBI 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 FNBI or any FNBI Subsidiary in connection with this Agreement
and the Merger Agreement or the transactions contemplated hereby and thereby.

        (t) Administration of Trust Accounts. Each of FNBI and the FNBI
            --------------------------------
Subsidiaries has properly administered in all respects material and which could
reasonably be expected to be material to the financial condition of FNBI and the
FNBI 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 FNBI,
any FNBI Subsidiary, nor to the best knowledge of FNBI any director, officer or
employee of FNBI or any FNBI 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 the financial condition of FNBI and the FNBI
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 FNBI nor any FNBI 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 FNBI and the FNBI Subsidiaries taken as a whole. To the best of FNBI's
knowledge, all parties with whom FNBI or any FNBI Subsidiary has material
leases, agreements or contracts or who owe to FNBI or any FNBI Subsidiary
material obligations, other than with respect to those arising in the ordinary
course of the banking business of the FNBI 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 on FNBI or any FNBI
Subsidiary of, any liability related to the release of hazardous substances as
defined 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 ("CERCLA"), pending
or, to the best of FNBI's knowledge, threatened against FNBI or any FNBI
Subsidiary the result of which has had or could reasonably be expected to have a
material adverse effect upon FNBI and FNBI's Subsidiaries taken as a whole; to
the best of FNBI's knowledge there is no reasonable basis for any such
proceeding, claim or action; and to the best of FNBI's knowledge neither FNBI
nor any FNBI 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. FNBI has provided Norwest with copies of all
environmental assessments, reports, studies and other documents in its
possession that set forth the results of investigations designed to assess
compliance with or liability under environmental laws with respect to each bank
facility and each non-residential OREO property.

        3. Representations and Warranties of Norwest. Norwest represents and

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

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

        (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 September 30, 1996 included in Norwest's
Quarterly Report on Form 10-Q for the period then ended, and to 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 September 30, 1996, 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 September 30, 1996, 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); or

                                      A-12
<PAGE>
 
               (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. Each of Norwest and the Norwest Subsidiaries is presently
            ---------
insured or self-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. Each of Norwest and the Norwest Subsidiaries
            --------------------
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.

        (o)  Norwest Benefit Plans.
             ---------------------

               (i) As of May 1, 1996, 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)(i) (the "Norwest Plans"). No Norwest Plan is a
        "multi-employer plan" within the meaning of Section 3(37) of ERISA.

                                      A-13
<PAGE>
 
               (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)(ii), Norwest or the
        Norwest Subsidiaries have applied for favorable determination letters
        from the Internal Revenue Service under the provisions of TRA `86 for
        the Norwest Corporation Pension Plan and the Norwest Corporation Savings
        Investment Plan. 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
        knows of no reason that each related trust is not exempt from taxation
        under Section 501(a) of the Code.

               (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
        as of the end of the most recent Plan year, 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)(iv), and to the best
        knowledge of Norwest, no Norwest Plan or any trust created thereunder,
        or 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 has 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, or any trustee,
        fiduciary or administrator thereof, or any party dealing with any 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)(v), 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 Merger 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), during the last five Norwest
        Plan years which would result in a material liability.

               (vii) Neither the execution and delivery of this Agreement and
        the Merger 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 or (iii) result in the acceleration of the time of payment or
        vesting of any such benefits to any material extent.

        (p) Registration Statement, etc. None of the information regarding
            ---------------------------
Norwest and its subsidiaries supplied or to be supplied by Norwest for inclusion
in (i) the Registration Statement, (ii) the Proxy Statement, or (iii) any other
documents to be filed with the SEC or any regulatory authority in connection
with the transactions contemplated hereby or by the Merger 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, and, in the
case of the 

                                      A-14
<PAGE>
 
Proxy Statement as amended or supplemented at the time of the meeting of
shareholders referred to in paragraph 4(c), contain an untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. All documents Norwest and the Norwest Subsidiaries are
responsible for filing with the SEC and with any other regulatory authority in
connection with the Merger will comply as to form in all material respects with
the provisions of applicable law.

        (q) Brokers and Finders. Neither Norwest nor any Norwest Subsidiary nor
            -------------------

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

defined under any local, state or federal environmental statute, regulation or
ordinance including, without limitation, CERCLA, pending or to the best of

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.

liquidation or consolidation or merger. Notwithstanding anything to the contrary
contained in this paragraph 5(n), nothing contained herein shall require Norwest
or FNBI to indemnify any person who was a director, officer or employee of FNBI
or any FNBI Subsidiary to a greater extent than FNBI or any FNBI Subsidiary is,
as of the date of this Agreement, required to indemnify any such person.

        (o) Directors' & Officers' Liability Insurance. For a period of three
            ------------------------------------------
years after the Effective Time of the Merger, Norwest shall use its best efforts
to cause to be maintained in effect the current policies of directors' and
officers' liability insurance maintained by FNBI (provided that Norwest may
substitute therefor policies of at least the same coverage and amount containing
terms and conditions which are substantially no less advantageous) with respect
to claims arising from facts or events which occurred before the Effective Time
of the Merger; provided, however, that in no event shall Norwest be obligated to
               --------  -------
expend, in order to maintain or provide insurance coverage pursuant to this
paragraph 5(o) any amount per annum in excess of 125% of the amount of the
annual premiums paid as of the date hereof by FNBI for such insurance (the
"Maximum Amount") and provided further that, prior to the Effective Time of the
Merger, FNBI shall notify the appropriate directors' and officers' liability
insurers of the Merger and of all pending or threatened claims, actions, suits,
proceedings or investigations asserted or claimed against any officer, director,
employee or other person covered by such policies, or circumstances likely to
give rise thereto, in accordance with terms and conditions of the applicable
policies. If the amount of the annual premiums necessary to maintain or procure
such insurance coverage exceeds the Maximum Amount, Norwest shall use reasonable
efforts to maintain the most advantageous policies of directors' and officers'
insurance obtainable for an annual premium equal to the Maximum Amount.

        (p) Exchange of Shares. At or prior to the Effective Time of the Merger,
            ------------------

Minnesota, N.A. (the "Agent"), for the benefit of the holders of certificates
representing shares of FNBI Common Stock (the "Certificates"), for exchange in

upon the making of an affidavit of that fact by the person claiming such
Certificate to be lost, stolen or destroyed and, if required by Norwest, the
posting by such person of a bond in such amount as Norwest may reasonably direct
as indemnity against any claim that may be made against it with respect to such
Certificate, the Agent will issue in exchange for such lost, stolen or destroyed
Certificate the shares of Norwest Common Stock and cash in lieu of fractional
shares deliverable in respect thereof pursuant hereto and the Merger Agreement.

        As soon as practicable after the Effective Time of the Merger, the Agent
shall mail to each holder of record of a Certificate or Certificates a form

Stock and the cash in lieu of fractional shares into which the shares of Company
Common Stock represented by such certificates shall have been converted pursuant
hereto and the Merger Agreement.

        (q) Delivery of Norwest Reports. From the date hereof to the Effective
            ---------------------------

For the purpose of determining each FNBI Employee's benefit for the year in

        FIRST: At the time of merger, Merger Co. shall be merged with and into

as follows:

               4.2. Number, Tenure and Qualifications. The board of directors of

                                      B-2
<PAGE>
 
        1. Each share of Company Common Stock outstanding immediately prior to
        the time of the merger (other than shares as to which statutory
        dissenters' appraisal rights have been exercised) will be converted into
        and exchanged for the number of shares of Norwest Common Stock
        determined by dividing the Adjusted Norwest Shares (as defined below) by
        the number of shares of Company Common Stock then outstanding. The
        "Adjusted Norwest Shares" shall mean the following:

               (a) If 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 20 trading days ending on the
               day immediately preceding the meeting of the shareholders of
               Company held to vote on this Agreement and the Reorganization
               Agreement (the "Norwest Measurement Price") is equal to or
               greater than $40.25, the Adjusted Norwest Shares shall be
               304,472.

               (b) If the Norwest Measurement Price is equal to or less than
               $36.25, the Adjusted Norwest Shares shall be 338,069.

               (c) If the Norwest Measurement Price is less than $40.25, but
               more than $36.25, the Adjusted Norwest Shares shall be the number
               determined by dividing $12,255,000 by the Norwest Measurement
               Price.

        2. As soon as practicable after the merger becomes effective, each
        holder of a certificate for shares of Company Common Stock outstanding
        immediately prior to the time of merger shall be entitled, upon
        surrender of such certificate for cancellation to the surviving
        corporation or to Norwest Bank Minnesota, National Association, as the
        designated agent of the surviving corporation (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 set forth in
        paragraph 1 above. Until so surrendered each certificate which,
        immediately prior to the time of merger, represented shares of Company
        Common Stock shall not be transferable on the books of the surviving
        corporation but shall be deemed to evidence the right to receive (except
        for the payment of dividends as provided below) ownership of the number
        of whole shares of Norwest Common Stock into which such shares of
        Company Common Stock have been converted on the basis above set forth;
        provided, however, until the holder of such certificate for Company
        Common Stock 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, if any,
        represented by such certificate, but, upon surrender and exchange
        thereof as herein provided, there shall be paid by the surviving
        corporation 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.

        3. If between the date of the Reorganization Agreement and the time of
        merger, 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, readjustment, or similar transaction, 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
        Company 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 Company Common
        Stock shall be converted will equal the number of shares of Norwest
        Common Stock which the holder of a share of Company Common Stock would

                                      B-3
<PAGE>
 
        have received pursuant to such reclassification, recapitalization,
        split-up, combination, exchange of shares, readjustment, or similar
        transaction, or stock dividend, had the record date therefor been
        immediately following the time of merger.

        4. 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 date of merger.

        5. Each share of Merger Co. Common Stock issued and outstanding at the
        time of merger shall be converted into and exchanged for one share of
        the surviving corporation after the time of merger.

        SEVENTH:  The merger provided for by this Agreement shall be effective
as follows:

        1. The effective date of merger shall be the date on which Articles of
        Merger (as described in subparagraph 1(b) of this Article Seventh) shall
        be delivered to and filed and accepted by the State Corporation

               information required by the New Mexico Business Corporation Act,
               shall be executed by the Chairman of the Board, the President or
               a Vice President of Merger Co. and by the Secretary or an
               Assistant Secretary of Merger Co., and by the Chairman of the
               Board, the President or a Vice President of Company and by the
               Secretary or an Assistant Secretary of Company, and shall be
               filed in the office of the State Corporation Commission of the
               State of New Mexico in accordance with the New Mexico Business
               Corporation Act.

        2. The merger shall become effective as of 11:59 p.m. (the "time of
        merger") on the effective date of merger.

        EIGHTH:  At the time of merger:

        1.     The separate  existence of Merger Co. shall cease, and the

        corporation the title to any property or rights of Merger Co. acquired

53-15-3   Right of Shareholders to Dissent and Obtain Payment for Shares

        A. Any shareholder of a corporation may dissent from, and obtain payment
for the shareholder's shares in the event of, any of the following corporate
actions:

               (1) any plan of merger or consolidation to which the corporation
        is a party, except as provided in Subsection C of this section;

               (2) any sale of exchange of all or substantially all of the
        property and assets of the corporation not made in the usual and regular
        course of its business, including a sale in dissolution, but not
        including a sale pursuant to an order of a court having jurisdiction in
        the premises or a sale for cash on terms requiring that all or
        substantially all of the net proceeds of sale be distributed to the
        shareholders in accordance with their respective interests within one
        year after the date of sale;

               (3) any plan of exchange to which the corporation is a party as
        the corporation the shares of which are to be acquired;

               (4) any amendment of the articles of incorporation which
        materially and adversely affects the rights appurtenant to the shares of
        the dissenting shareholder in that it:

                      (a) alters or abolishes a preferential right of such
shares;

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

                      (c) alters or abolishes an existing preemptive right of
               the holder of such shares to acquire shares or other securities;
               or

                      (d) excludes or limits the right of the holder of such
               shares to vote on any matter, or to cumulate his votes, except as
               such right may be limited by dilution through the issuance of
               shares or other securities with similar voting rights; or

               (5) any other corporate action taken pursuant to a shareholder
        vote with respect to which the articles of incorporation, the bylaws or
        a resolution of the board of directors directs that dissenting
        shareholders shall have a right to obtain payment for their shares.

        B. (1) A record holder of shares may assert dissenters' rights as to
less than all of the shares registered in his name only if the holder dissents
with respect to all the shares beneficially owned by any one person and
discloses the name and address of the person or persons on whose behalf the
holder dissents. In that event, his rights shall be determined as if the shares
as to which he has dissented and his other shares were registered in the names
of different shareholders.

               (2) A beneficial owner of shares who is not the record holder may
assert dissenters' rights with respect to shares held on his behalf, and shall
be treated as a dissenting shareholder under the terms of this section and
Section 53-15-4 NMSA 1978 if he submits to the corporation at the time of or
before the assertion of these rights a written consent of the record holder.

                                      C-1
<PAGE>
 
        C. The right to obtain payment under this section shall not apply to the
shareholders of the surviving corporation in a merger if a vote of the
shareholders of such corporation is not necessary to authorize such merger.

        D. A shareholder of a corporation who has a right under this section to
obtain payment for his shares shall have no right at law or in equity to attack
the validity of the corporate action that gives rise to his right to obtain
payment, nor to have the action set aside or rescinded, except when the
corporate action is unlawful or fraudulent with regard to the complaining
shareholder or to the corporation.

53-15-4   Rights of Dissenting Shareholders

        A. Any shareholder electing to exercise his right of dissent shall file
with the corporation, prior to or at the meeting of shareholders at which the
proposed corporate action is submitted to a vote, a written objection to the
proposed corporate action. If the proposed corporate action is approved by the
required vote and the shareholder has not voted in favor thereof, the
shareholder may, within ten days after the date on which the vote was taken or
if a corporation is to be merged without a vote of its shareholders into another
corporation any of its shareholders may, within twenty-five days after the plan
of the merger has been mailed to the shareholders, make written demand on the
corporation, or, in the case of a merger or consolidation, on the surviving or
new corporation, domestic or foreign, for payment of the fair value of the
shareholder's shares, and, if the proposed corporate action is effected, the
corporation shall pay to the shareholder, upon the determination of the fair
value, by agreement or judgment as provided herein, and, in the case of shares
represented by certificates, the surrender of such certificates the fair value
thereof as of the day prior to the date on which the vote was taken approving
the proposed corporate action, excluding any appreciation or depreciation in
anticipation of the corporate action. Any shareholder failing to make demand
within the prescribed ten-day or twenty-five day period shall be bound by the
terms of the proposed corporate action. Any shareholder making such demand shall
thereafter be entitled only to payment as in this section provided and shall not
be entitled to vote or to exercise any other rights of a shareholder.

        B. No such demand may be withdrawn unless the corporation consents
thereto. If, however, the demand is withdrawn upon consent, or if the proposed
corporate action is abandoned or rescinded or the shareholders revoke the
authority to effect the action, or if, in the case of a merger, on the date of
the filing of the articles of merger the surviving corporation is the owner of
all the outstanding shares of the other corporation, domestic and foreign, that
are parties to the merger, or if no demand or petition for the determination of
fair value by a court has been made or filed within the time provided in this
section, or if a court of competent jurisdiction determines that the shareholder
is not entitled to the relief provided by this section, then the right of the
shareholder is to be paid the fair value of his shares ceases and his status as
a shareholder shall be restored, without prejudice, to any corporate proceedings
which may have been taken during the interim.

        C. Within ten days after such corporate action is effected, the
corporation, or, in the case of a merger or consolidation, the surviving or new
corporation, domestic or foreign, shall give written notice thereof to each
dissenting shareholder who has made demand as provided in this section and shall
make a written offer to each such shareholder to pay for such shares at a
specified price deemed by the corporation to be the fair value thereof. The
notice and offer shall be accompanied by a balance sheet of the corporation, the
shares of which the dissenting shareholder holds, as of the latest available
date and not more than twelve months prior to the making of the offer, and a
profit and loss statement of the corporation for the twelve-months' period ended
on the date of the balance sheet.

        D. If within thirty days after the date on which the corporate action
was effected the fair value of the shares is agreed upon between any dissenting
shareholder and the corporation, payment therefor shall be made within ninety
days after the date on which the corporate action was effected, and, in the case
of shares represented by certificates, upon surrender of the certificates. Upon
payment of the agreed value, the dissenting shareholder shall cease to have any
interest in the shares.

                                      C-3
<PAGE>
 
        E. If, within the period of thirty days, a dissenting shareholder and
the corporation do not so agree, then the corporation, within thirty days after
receipt of written demand from any dissenting shareholder, given within sixty
days after the date on which corporate action was effected, shall, or at its
election at any time within the period of sixty days may, file a petition in any
court of competent jurisdiction in the county in this state where the registered
office of the corporation is located praying that the fair value of the shares
be found and determined. If, in the case of a merger or consolidation, the
surviving or new corporation is a foreign corporation without a registered
office in this state, the petition shall be filed in the county where the
registered office of the domestic corporation was last located. If the
corporation fails to institute the proceeding as provided in this section, any
dissenting shareholder may do so in the name of the corporation. All dissenting
shareholders, wherever residing, shall be made parties to the proceeding as an
action against their shares quasi in rem. A copy of the petition shall be served
on each dissenting shareholder who is a resident of this state and shall be
served by registered or certified mail on each dissenting shareholder who is a
nonresident. Service on nonresidents shall also be made by publication as
provided by law. The jurisdiction of the court shall be plenary and exclusive.
All shareholders who are parties to the proceeding shall be entitled to judgment
against the corporation for the amount of the fair value of their shares. The
court may, if it so elects, appoint one or more persons as appraisers to receive
evidence and recommend a decision on the question of fair value. The appraisers
shall have such power and authority as specified in the order of their
appointment or on an amendment thereof. The judgment shall be payable to the
holders of uncertificated shares immediately, but to the holders of shares
represented by certificates only upon and concurrently with the surrender to the
corporation of certificates. Upon payment of the judgment, the dissenting
shareholder ceases to have any interest in the shares.

        F. The judgment shall include an allowance for interest at such rate as
the court may find to be fair and equitable, in all circumstances, from the date
on which the vote was taken on the proposed corporate action to the date of
payment.

        G. The costs and expenses of any such proceeding shall be determined by
the court and shall be assessed against the corporation, but all or any part of
the costs and expenses may be apportioned and assessed as the court deems
equitable against any or all of the dissenting shareholders who are parties to
the proceeding to whom the corporation made an offer to pay for the shares if
the court finds that the action of the shareholders in failing to accept the
offer was arbitrary or vexatious or not in good faith. Such expenses include
reasonable compensation for and reasonable expenses of the appraisers, but
exclude the fees and expenses of counsel for and experts employed by any party;
but if the fair value of the shares as determined materially exceeds the amount
which the corporation offered to pay therefor, or if no offer was made, the
court in its discretion may award to any shareholder who is a party to the
proceeding such sum as the court determines to be reasonable compensation to any
expert employed by the shareholder in the proceeding, together with reasonable
fees of legal counsel.

        H. Upon receiving a demand for payment from any dissenting shareholder,
the corporation shall make an appropriate notation thereof in its shareholder
records. Within twenty days after demanding payment for his shares, each holder
of shares represented by certificates demanding payment shall submit the
certificates to the corporation for notation thereon that such demand has been
made. His failure to do so shall, at the option of the corporation, terminate
his rights under this section unless a court of competent jurisdiction, for good
and sufficient cause shown, otherwise directs. If uncertificated shares for
which payment has been demanded or shares represented by a certificate on which
notation has been so made are transferred, any new certificate issued therefor
shall bear similar notation, together with the name of the original dissenting
holder of the shares, and a transferee of 

                                      C-4
<PAGE>
 
the shares acquires by such transfer no rights in the corporation other than
those which the original dissenting shareholder had after making demand for
payment of the fair value thereof.

        I. Shares acquired by a corporation pursuant to payment of the agreed
value therefor or to payment of the judgment entered therefor, as in this
section provided, may be held and disposed of by the corporation as in the case
of other treasury shares, except that, in the case of a merger or consolidation,
they may be held and disposed of as the plan of merger or consolidation may
otherwise provide.

ITEM 22.   UNDERTAKINGS

    (a) The undersigned registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
            a posteffective 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 posteffective amendment thereof) which, individually
            or in the aggregate, represent a fundamental change in the
            information set forth in the registration statement. Notwithstanding
            the foregoing, any increase or decrease in volume of securities
            offered (if the total dollar value of securities offered would not
            exceed that which was registered) and any

                                      II-2
<PAGE>
 
            deviation from the low or high end of the estimated maximum offering
            range may be reflected in the form of prospectus filed with the
            Commission pursuant to Rule 424(b) (ss.230.424(b) of this chapter)
            if, in the aggregate, the changes in volume and price represent no
            more than 20% change in the maximum offering price set forth in the
            "Calculation of Registration Fee" table in the effective
            registration statement.

                       (iii) To include any material information with respect to
            the plan of distribution not previously disclosed in the
            registration statement or any material change to such information in
            the registration statement.

        (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 posteffective 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

                                      II-3
<PAGE>
 
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.

Ladies and Gentlemen:

        In connection with the proposed registration under the Securities Act of
1933, as amended, of up to 375,000 shares of common stock, par value $1-2/3 per
share (the "Shares"), of Norwest Corporation, a Delaware corporation (the
"Corporation"), which are proposed to be issued by the Corporation in connection
with the merger (the "Merger") of a wholly-owned subsidiary of the Corporation
with The First National Bankshares, Inc., a New Mexico corporation, 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
Merger, 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
