                            BELEN, NEW MEXICO  87002


                                 November __, 1994

  Dear Shareholder:

  You are cordially invited to attend a Special Meeting of Shareholders of
  American Republic Bancshares, Inc. ("ARBI") to be held in the Fourth Floor
  Training Room of the First National Bank of Belen, 101 South Main Street,
  Belen, New Mexico, on Friday, December 9, 1994, at 10:00 a.m., local time.  At
  the Special Meeting you will be asked to consider and vote upon the Agreement
  and Plan of Reorganization, dated as of June 6, 1994, between ARBI and Norwest
  Corporation ("Norwest"), and the related Agreement and Plan of Merger
  (together, the "Merger Agreement"), providing for the merger of a wholly owned
  subsidiary of Norwest with ARBI (the "Merger").

  Under the terms of the Merger Agreement, the Merger will result in the
  conversion of each share of ARBI Common Stock outstanding immediately prior to
  the time the Merger becomes effective into a number of shares of Norwest
  Common Stock determined in accordance with the provisions of the Merger
  Agreement, which are described in the accompanying Proxy Statement-Prospectus
  for the Special Meeting.

  The enclosed Proxy Statement-Prospectus contains a more complete description
  of the terms of the Merger.  You are urged to read the Proxy Statement-
  Prospectus carefully.

  The Board of Directors has unanimously approved the Merger Agreement as being
  in the best interest of ARBI's shareholders and recommends that you vote in
  favor of the Merger.  ARBI has received an opinion from Montgomery Securities,
  an investment banking firm experienced in the valuation of banking
  institutions, that as of the date thereof the consideration to be received by
  ARBI's shareholders in the Merger is fair to ARBI's shareholders from a
  financial point of view.  Also, it is a condition to consummation of the
  Merger that ARBI receive at closing an opinion of counsel to the effect that
  the Merger will be treated as a tax-free reorganization for federal income tax
  purposes.  The Merger Agreement also provides for ARBI's formation of a
  liquidating trust to hold certain assets of ARBI prior to the Merger and the
  distribution of interests in such trust to the ARBI shareholders.  This
  distribution will be taxable to the shareholders of ARBI.  YOU SHOULD CONSULT
  YOUR OWN TAX ADVISOR CONCERNING THE FEDERAL, AND ANY APPLICABLE FOREIGN,
  STATE, AND LOCAL, INCOME TAX CONSEQUENCES OF THE MERGER.

  In order to ensure that your vote is represented at the Special Meeting,
  PLEASE DATE, SIGN, AND PROMPTLY RETURN YOUR PROXY IN THE ENCLOSED ENVELOPE.
  If you attend the meeting, you may vote in person if you wish, even though you
  have previously returned your proxy.



                                     James H. Foley

                               PROXY STATEMENT OF
                       AMERICAN REPUBLIC BANCSHARES, INC.
                     FOR A SPECIAL MEETING OF SHAREHOLDERS
                         TO BE HELD ON DECEMBER 9, 1994

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

                                   PROSPECTUS
                                       OF
                              NORWEST CORPORATION
                                  COMMON STOCK

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

      This Proxy Statement-Prospectus relates to up to 1,266,000 shares of the
  common stock ("Norwest Common Stock"), par value $1 2/3 per share, of Norwest
  Corporation ("Norwest") issuable to the shareholders of American Republic
  Bancshares, Inc.  ("ARBI") upon consummation of the proposed merger (the
  "Merger") of a wholly owned subsidiary of Norwest with ARBI, with ARBI as the
  surviving corporation, pursuant to the terms of an Agreement and Plan of
  Reorganization, dated as of June 6, 1994, as amended, between ARBI and Norwest
  (together with the Agreement and Plan of Merger attached thereto, the "Merger
  Agreement").  A copy of the Merger Agreement is attached as Appendix A to this
  Proxy Statement-Prospectus and incorporated by reference herein.

      This Proxy Statement-Prospectus is being furnished to the shareholders of
  ARBI in connection with the solicitation of proxies by the Board of Directors
  of ARBI for use at the Special Meeting of Shareholders of ARBI to be held on
  December 9, 1994, and at any adjournments or postponements thereof (the
  "Special Meeting").

      Except as described herein, upon consummation of the Merger, each
  outstanding share of Common Stock, par value $1.00 per share, of ARBI ("ARBI
  Common Stock") will be converted into a number of shares of Norwest Common
  Stock determined in accordance with a formula contained in the Merger
  Agreement.  The actual number of shares of Norwest Common Stock to be issued
  upon consummation of the Merger will be based in part on the market price of
  Norwest Common Stock determined during a measurement period provided for in
  the Merger Agreement.  Based on the conversion factor which would have been
  applicable if the closing of the Merger had occurred on November __, 1994,
  approximately _____ shares of Norwest Common Stock would have been issued for
  each outstanding share of ARBI Common Stock.  For a more complete description
  of the Merger Agreement and the terms of the Merger, see "THE MERGER."

      The Merger Agreement also provides that, immediately prior to the Merger,
  ARBI will form a liquidating trust, for the pro rata benefit of its
  shareholders, and that ARBI will distribute to such trust certain of ARBI's
  assets.  The receipt by the shareholders of ARBI of their ratable interests in
  the assets held by the trust will be taxable to the shareholders of ARBI as a
  dividend.  See "THE MERGER--Terms of the Merger" and "--Certain Federal Income
  Tax Considerations."

      This Proxy Statement-Prospectus and the form of proxy are first being
  mailed to shareholders of ARBI on or about November __, 1994.

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

         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

  THE COMPANIES

       NORWEST CORPORATION

       Norwest Corporation is a regional bank holding company which was
  organized under the laws of Delaware in 1929 and is registered under the Bank
  Holding Company Act of 1956, as amended (the "BHC Act").  As a diversified
  financial services organization, Norwest operates through subsidiaries engaged
  in banking and in related businesses.  Norwest provides retail, commercial,
  and corporate banking services to its customers through banks located in
  Arizona, Colorado, Illinois, Iowa, Minnesota, Montana, Nebraska, New Mexico,
  North Dakota, Ohio, South Dakota, Texas, Wisconsin, and Wyoming.  Norwest
  provides additional financial services to its customers through subsidiaries
  engaged in various businesses, principally mortgage banking, consumer finance,
  equipment leasing, agricultural finance, commercial finance, securities
  brokerage and investment banking, insurance, computer and data processing
  services, trust services, and venture capital investments.

       At June 30, 1994, Norwest had consolidated total assets of $55.8 billion,
  total deposits of $34.7 billion, and total stockholders' equity of $3.8
  billion.  Based on total assets at June 30, 1994, Norwest was the 13th largest
  commercial banking organization in the United States.

       Norwest regularly explores opportunities for acquisitions of financial
  institutions and related businesses.  Generally, management of Norwest does
  not make a public announcement about an acquisition until a definitive
  agreement has been signed.  Norwest has entered into definitive agreements for
  the acquisition of various financial institutions, including ARBI, having
  aggregate total assets at June 30, 1994, of approximately $3.3 billion.
  Certain of these acquisitions were consummated subsequent to June 30, 1994,
  and the others remain subject to regulatory approval and are expected to be
  completed by the end of the first quarter of 1995.  None of these acquisitions
  are significant for the financial statements of Norwest, either individually
  or in the aggregate.

       Norwest's principal executive offices are located at Norwest Center,
  Sixth and Marquette, Minneapolis, Minnesota 55479-1000, and its telephone
  number is 612-667-1234.

  TERMS OF THE MERGER

      The Merger Agreement provides for the merger of a wholly owned subsidiary
  of  Norwest with ARBI, with ARBI as the surviving corporation.  Upon
  consummation of the Merger, the outstanding shares of ARBI Common Stock (other
  than shares as to which statutory dissenters' rights have been exercised and
  not forfeited) will be converted into a number of shares of Norwest Common
  Stock determined in accordance with the provisions of the Merger Agreement.
  The exact number of shares of Norwest Common Stock into which each outstanding
  share of ARBI Common Stock will be converted will be determined by a
  conversion factor based on the average of the closing prices of Norwest Common
  Stock during a specified period and the number of shares of ARBI Common Stock
  outstanding at the Effective Time of the Merger (as defined below).  The
  Merger Agreement also provides that, immediately prior to the Merger, ARBI
  will form a liquidating trust, for the pro rata benefit of its shareholders,
  and that ARBI will distribute to such trust certain of its assets.  The
  receipt by the shareholders of ARBI of their ratable interests in the assets 
  held by the trust will be taxable to the shareholders of ARBI as a dividend.
  See "THE MERGER--Terms of the Merger," "--Liquidating Trust," and "--Certain
  Federal Income Tax Considerations."

  SPECIAL MEETING AND VOTE REQUIRED

      SPECIAL MEETING

      The special meeting of ARBI shareholders to consider and vote on the
  Merger will be held on Friday, December 9, 1994, at 10:00 a.m., local time, in
  the Fourth Floor Training Room of the Bank, 101 South Main Street, Belen, New
  Mexico.  Only holders of record of ARBI Common Stock at the close of business
  on November __, 1994, will be entitled to

                                       6
<PAGE>
 
  receive notice of and to vote at the Special Meeting.  At such date, there
  were 410,095 shares of ARBI Common Stock outstanding.  Each share of ARBI
  Common Stock is entitled to one vote.  For additional information relating to
  the Special Meeting, see "MEETING INFORMATION."

      VOTE REQUIRED

      Approval of the Merger Agreement requires the affirmative vote of the
  holders of a majority of the outstanding shares of ARBI Common Stock.  As of
  the record date for the Special Meeting, directors and executive officers of
  ARBI and their affiliates owned beneficially or controlled the voting of an
  aggregate of 78,818.9 shares of ARBI Common Stock, or approximately 19.2% of
  the shares of ARBI Common Stock outstanding on that date.  ARBI's directors
  and officers have informed ARBI that they intend to vote all of their shares
  in favor of approval of the Merger Agreement.  At the record date, directors
  and executive officers of Norwest did not own beneficially any shares of ARBI
  Common Stock.  See "MEETING INFORMATION--Record Date; Vote Required" and 
  "--Principal Shareholders and Security Ownership of Management of ARBI."

  REASONS FOR THE MERGER; RECOMMENDATION OF ARBI BOARD OF DIRECTORS

      In reaching its determination to enter into the Merger Agreement, ARBI's
  Board of Directors consulted with Montgomery Securities and ARBI's legal
  advisors, and considered a number of factors, including but not limited to the
  following:  the oral opinion of Montgomery Securities, subsequently confirmed
  in writing, that as of June 6, 1994, the consideration to be received by the
  shareholders of ARBI pursuant to the Merger Agreement was fair to such
  shareholders from a financial point of view; the current and prospective
  economic environment and competitive constraints facing independent community-
  based financial institutions, including the Bank, including the possible
  effects of congressional approval of interstate banking; ARBI Board's view of
  reasonably available alternatives for the shareholders, including continuing
  to operate as an independent community-based financial institution; the
  economies of scale available to larger financial institutions, including the
  ability of such institutions to develop new and innovative financial products
  for customers; the nonfinancial terms of the Merger Agreement, including the
  risks to completion of the Merger inherent in the conditions to consummation
  of the transaction included therein; and the increased liquidity and
  diversification of risk that the Merger would provide to ARBI's shareholders.
  See "THE MERGER--Background of and Reasons for the Merger."

      THE BOARD OF DIRECTORS OF ARBI UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS
  VOTE FOR THE MERGER.


  FAIRNESS OPINION

      Montgomery Securities has delivered its written opinion to ARBI's Board of
  Directors that, as of the date of this Proxy Statement-Prospectus, the
  consideration to be received by the ARBI shareholders in the Merger is fair to
  ARBI's shareholders from a financial point of view.  A copy of this opinion is
  attached hereto as Appendix B.  See "THE MERGER--Fairness Opinion."

                                       7

  EFFECTIVE DATE AND TIME OF THE MERGER

      Subject to the terms and conditions of the Merger Agreement, the Merger
  will be effective on the date on which the appropriate filing is made with the
  Secretary of State of the State of New Mexico (the "Effective Date of the
  Merger") at 11:59 p.m., New Mexico time (the "Effective Time of the Merger").
  Such filing shall be made five business days following the satisfaction or
  waiver of all conditions set forth in the Merger Agreement or on such other
  date upon which the parties may agree.  The closing of the Merger will occur
  on the Effective Date of the Merger (the "Closing Date").  See 
  "THE MERGER--Effective Date and Time of the Merger" and 
  "--Conditions to the Merger."
 
  CONDITIONS AND TERMINATION

      The respective obligations of Norwest and ARBI to consummate the Merger
  are subject to certain conditions, including the receipt of regulatory
  approvals without unduly burdensome conditions, approval of the Merger
  Agreement by the shareholders of ARBI, receipt by ARBI of an opinion regarding
  the tax consequences to ARBI shareholders of the Merger, and certain other
  conditions customary in transactions of this nature.  See "THE MERGER--
  Conditions to the Merger" and "THE MERGER--Regulatory Approvals."

      The Merger Agreement may be terminated at any time prior to the time at
  which the appropriate filing is made with the Secretary of State of the State
  of New Mexico, whether prior to or after approval by ARBI's shareholders, by
  either party under specified conditions, including if the Merger shall not
  have been consummated by May 15, 1995, unless failure to consummate is due to
  the failure of the party seeking termination to perform its respective
  covenants and agreements under the Merger Agreement.  In addition, ARBI may
  terminate the Merger Agreement if the average price per share of Norwest
  Common Stock over a specified period falls below $20.00 or below a benchmark
  price computed by reference to the stock prices of a specified group of
  regional bank holding companies.  See "THE MERGER--Waiver, Amendment, and
  Termination."

  ACCOUNTING TREATMENT

      Management of Norwest anticipates that the Merger will be accounted for as
  a purchase under generally accepted accounting principles.  See "THE MERGER--
  Accounting Treatment."

  REGULATORY APPROVALS

      The Merger is subject to the prior approval of the Board of Governors of
  the Federal Reserve System (the "Federal Reserve Board").  The approval of
  the Federal Reserve Board has been received.  See "THE MERGER--Regulatory
  Approvals."

  MANAGEMENT AND OPERATIONS AFTER THE MERGER

      Following the Merger, Norwest intends to operate at the Bank's present
  locations and to offer products and services offered by Norwest affiliates.
  Norwest plans to consolidate the Bank's branch in Moriarty and Norwest Bank
  New Mexico, N.A.'s branch in Moriarty.  See "THE MERGER--Management and
  Operations After the Merger."

                                       8
<PAGE>
 
  INTERESTS OF CERTAIN PERSONS IN THE MERGER

      Certain executive officers and members of the Boards of Directors of ARBI
  and the Bank have certain interests in the Merger that are in addition to
  their interests as shareholders of ARBI generally.  These interests include,
  among others, provisions in the Merger Agreement relating to indemnification
  of such parties and the continuation of certain employee benefits.  In
  addition, Mr. James H. Foley may receive additional compensation pursuant to
  an arrangement with ARBI if his employment is terminated following the Merger
  under certain circumstances.  See "MANAGEMENT OF ARBI--Interests of Management
  and Others in Certain Transactions."

  DISSENTERS' RIGHTS

      Under New Mexico law, ARBI shareholders who dissent from the Merger are
  entitled to obtain payment of the fair value of their shares instead of
  receiving Norwest Common Stock in the Merger.  Failure to comply with
  statutory procedures in the exercise of dissenters' rights will nullify such
  rights.  See "THE MERGER--Rights of Dissenting ARBI Shareholders."

  CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

      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
  ("Code"), and that as a result, for federal income tax purposes (i) no gain or
  loss will be recognized by Norwest or ARBI as a result of the Merger, (ii) no
  gain or loss will be recognized by holders of ARBI Common Stock upon the
  receipt of Norwest Common Stock in exchange therefor pursuant to the Merger,
  except with respect to cash received in lieu of fractional shares and except
  for interests in the liquidating trust described below, and (iii) the
  aggregate adjusted tax basis of the shares of Norwest Common Stock to be
  received by holders of ARBI Common Stock will be the same as the aggregate
  adjusted tax basis of the shares of ARBI Common Stock exchanged therefor,
  reduced by the amount allocable to fractional share interests for which cash
  is received.  Consummation of the Merger is conditioned upon the receipt by
  ARBI of an opinion of Bracewell & Patterson, L.L.P., Houston, Texas, counsel
  for ARBI, substantially to such effect.  See "THE MERGER--Certain Federal
  Income Tax Considerations."

      The Merger Agreement also provides that, immediately prior to the
  Effective Date of the Merger, ARBI will form a liquidating trust for the
  benefit of its shareholders and that ARBI will distribute to such trust
  certain of ARBI's assets, including cash, certain securities, and artwork.
  ARBI will distribute interests in the trust pro rata to its shareholders.  The
  receipt by the shareholders of ARBI of their ratable interests in the assets
  held by the trust will be taxable to the shareholders of ARBI as a dividend.
  See "THE MERGER--Liquidating Trust" and "--Certain Federal Income Tax
  Considerations."

      Shareholders should consult with their own tax advisors regarding the tax
  consequences of the Merger in light of their personal tax situations.

  MARKET INFORMATION

       Norwest Common Stock is listed on the New York Stock Exchange (the
  "NYSE") and the Chicago Stock Exchange (the "CHX").  On June 3, 1994, the last
  trading day preceding

                                       9
<PAGE>
 
  public announcement of the proposed Merger, the closing price per share of
  Norwest Common Stock on the NYSE was $27.25 and on November __, 1994, the
  price was $__.__.  Shareholders of ARBI are advised to obtain current market
  quotations for Norwest Common Stock.  The market price for Norwest Common
  Stock will fluctuate between the date of this Proxy Statement-Prospectus and
  the Effective Date of the 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 ARBI ultimately receive in the Merger could be more or
  less than its market value on the date of this Proxy Statement-Prospectus.  No
  assurance can be given concerning the market price of Norwest Common Stock
  before or after the Effective Date of the Merger.

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

  CERTAIN DIFFERENCES IN RIGHTS OF SHAREHOLDERS

       Upon consummation of the Merger, shareholders of ARBI will become
  stockholders of Norwest.  As a result, such shareholders' rights will change
  significantly.  See "THE MERGER--Certain Differences in Rights of
  Shareholders."

  COMPARATIVE UNAUDITED PER SHARE DATA

     The following table presents selected comparative unaudited per share data
  for Norwest Common Stock on a historical and a pro forma combined basis and
  for ARBI Common Stock on a historical and a pro forma equivalent basis giving

</TABLE>

(1)  The pro forma combined book values per share of Norwest Common Stock are
based upon the historical total combined common equity for Norwest and ARBI
divided by total pro forma common shares of the combined entities assuming
conversion of the outstanding ARBI Common Stock at a conversion factor of
2.77455.  The difference between the historical total common equity of ARBI and
the total market value of Norwest Common Stock to be issued in the Merger is not
material.  The pro forma equivalent book values per share of ARBI Common Stock
represent the pro forma combined amounts multiplied by the assumed conversion
factor.  The assumed conversion factor used in this table is based on an assumed
aggregate number of shares of Norwest Common Stock to be issued in the Merger of
1,137,829 upon conversion of all outstanding shares of ARBI Common Stock.  The
number of shares of Norwest Common Stock to be issued in the Merger was computed
based on assumed proceeds of $2,202,474 from the sale of the ARBI Portfolio
Stock (as defined under "THE MERGER--Terms of the Merger") based on market
prices of such stock as of September 6, 1994, which was added to the base merger
consideration of $27,950,000, resulting in a total value of approximately $30.2
million.  This total value was divided by an assumed Norwest Measurement Price
(as defined under "THE MERGER--Terms of the Merger") as of September 6, 1994, of
$26.50.  The market price for the ARBI Portfolio Stock and for Norwest Common
Stock, and therefore the Norwest Measurement Price, will fluctuate between the
date of this Proxy Statement-Prospectus and the Effective Date of the Merger.
Accordingly, no assurance can be given concerning the actual conversion factor
which will apply on the Closing Date.  See "THE MERGER--Terms of the Merger."

(2)  Assumes no changes in cash dividends per share.  The pro forma equivalent
dividends per share of ARBI Common Stock  represent cash dividends declared per
share of Norwest Common Stock multiplied by 2.77455.

(3)  The pro forma combined net income per share (based on fully diluted net
income and weighted average shares outstanding) is based upon the combined
historical net income for Norwest and ARBI divided by the average pro forma
common shares of the combined entities, assuming a conversion factor of 2.77455.
The pro forma equivalent net income per share of ARBI Common Stock represents
the pro forma combined net income per share multiplied by 2.77455.

  (1)  On January 14, 1994, First United Bank Group, Inc. ("First United"), a
  $3.9 billion bank holding company headquartered in Albuquerque, New Mexico,
  was acquired in a pooling transaction.  Norwest's historical results have been
  restated to include the historical results of First United.  Appropriate
  Norwest items reflect an increase in First United's provision for credit
  losses of $16.5 million to conform with Norwest's credit loss reserve
  practices and methods and $83.2 million in accruals and reserves for merger-
  related expenses, including termination costs, systems and operations costs,
  and investment banking, legal, and accounting expenses.

  (2)  On February 9, 1993, Lincoln Financial Corporation ("Lincoln"), a $2.0
  billion bank holding company headquartered in Fort Wayne, Indiana, was
  acquired in a pooling transaction.  Norwest's historical results have been
  restated to include the historical results of Lincoln.  Appropriate Norwest
  items reflect an increase in Lincoln's provision for credit losses of $60.0
  million and $33.5 million in Lincoln's provisions and expenditures for costs
  related to restructuring activities.

  (3)  On April 19, 1991, United Banks of Colorado, Inc. ("United"), a $5.5
  billion financial institution headquartered in Denver, Colorado, merged with
  Norwest in a pooling transaction.  Norwest's historical results have been
  restated to include the historical results of United.  Appropriate Norwest
  items reflect United's special provisions for credit losses and writedowns for
  other real estate owned, which together totaled $165 million, and $31 million
  of accruals for expected reorganization and restructuring costs for the year
  ended December 31, 1990.  The special provisions were due to deterioration of
  several large commercial loan relationships, the anticipated results of the
  then recent examination by the Office of the Comptroller of the Currency, and
  the anticipated impact of the Resolution Trust Corporation's accelerated
  efforts to liquidate foreclosed properties at deep discounts.

  (4)  On May 1, 1990, First Interstate Corporation of Wisconsin ("FIWI"), a
  $2.0 billion financial institution headquartered in Sheboygan, Wisconsin,
  merged with Norwest in a pooling transaction.  Norwest's historical results
  have been restated to include the historical results of FIWI.  Appropriate
  Norwest items reflect $12.0 million in charges resulting from FIWI's decision
  to sell its portfolio of stripped mortgage-backed securities, an increase in
  FIWI's provision for credit losses of $16.2 million, and $24.5 million in
  FIWI's provisions and expenditures for costs related to restructuring
  activities.

  DATE, PLACE, AND TIME

      The Special Meeting will be held in the Fourth Floor Training Room of the
  Bank, 101 South Main Street, Belen, New Mexico, on Friday, December 9, 1994,
  at 10:00 a.m., local time.

  RECORD DATE; VOTE REQUIRED

      The Board of Directors of ARBI has fixed the close of business on November
  11, 1994, as the record date for the determination of shareholders of ARBI
  entitled to receive notice of, and to vote at, the Special Meeting.  On the
  record date there were 410,095 shares of ARBI Common Stock outstanding and
  entitled to vote at the Special Meeting.  Approval of the Merger Agreement
  requires the affirmative vote of the holders of a majority of the outstanding
  shares of ARBI Common Stock.  The Merger cannot be consummated without the
  requisite approval of the Merger Agreement by the holders of ARBI Common
  Stock.

      As of the record date for the Special Meeting, directors and officers of
  ARBI and their affiliates owned beneficially or controlled the voting of an
  aggregate of 78,818.9 shares of ARBI Common Stock or approximately 19.2% of
  the shares of ARBI Common Stock outstanding on that date.  ARBI's directors
  and officers have informed ARBI that they intend to vote all of their shares
  in favor of the Merger Agreement.  Information regarding the shares of ARBI
  Common Stock beneficially owned, directly or indirectly, by certain
  shareholders, by each director and executive officer of ARBI, and by all
  directors and officers as a group is set forth in the table under the heading
  "Principal Shareholders and Security Ownership of Management of ARBI" below.

      At the record date, directors and executive officers of Norwest did not
  own beneficially any shares of ARBI Common Stock.

  VOTING AND REVOCATION OF PROXIES

       Shares of ARBI 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 ARBI Common Stock represented by such proxy will be
  voted FOR approval of the Merger 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 ARBI prior to or at the
  Special Meeting or by voting the shares subject to the proxy in person at the
  Special Meeting.  Attendance at the Special Meeting will not in and of itself
  constitute a revocation of a proxy.

        A proxy may indicate that all or a portion of the shares represented
  thereby are not being voted with respect to a specific proposal.  This could
  occur, for example, when a broker is not permitted to vote shares held in
  street name on certain proposals in the absence of instructions from the
  beneficial owner.  Shares that are not voted with respect to a specific
  proposal will be considered as not present for such proposal, even though such
  shares will be considered present for purposes of determining a quorum and
  voting on other proposals.  Abstentions on a specific proposal will be
  considered as present, but not as voting in favor of such proposal.  The
  proposal to adopt the Merger Agreement must be approved by the holders of a
  majority of the outstanding ARBI Common Stock.  Because this proposal requires
  the affirmative vote of a specified percentage of outstanding shares, the
  nonvoting of shares or abstentions with regard to this proposal will have the
  same effect as votes against the proposal.

        The Board of Directors of ARBI is not aware of any business to be acted
  upon at the Special Meeting other than the business described herein.  If,
  however, other matters are properly brought before the Special Meeting, or any
  adjournments or postponements thereof, the persons appointed as proxies will
  have discretion to vote or act on such matters according to their best
  judgment.

  SOLICITATION OF PROXIES

       In addition to solicitation by mail, directors, officers, and employees
  of ARBI may solicit proxies from the shareholders of ARBI, either personally
  or by telephone, telegram, or other form of communication.  None of the
  foregoing persons who solicit proxies will be specifically compensated for
  such services.  Nominees, fiduciaries, and other custodians will be requested
  to forward soliciting materials to beneficial owners and will be reimbursed
  for their reasonable expenses incurred in sending proxy material to beneficial
  owners.  ARBI will bear its own expenses in connection with any solicitation
  of proxies for the Special Meeting.  See "THE MERGER--Expenses."

  ALL SHAREHOLDERS OF ARBI ARE REQUESTED TO COMPLETE, DATE, AND SIGN THE
  ACCOMPANYING PROXY AND RETURN IT PROMPTLY TO ARBI 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 Merger Agreement, which is
  attached as Appendix A to this Proxy Statement-Prospectus and is incorporated
  by reference herein.  All shareholders are urged to read the Merger Agreement
  in its entirety.

  BACKGROUND OF AND REASONS FOR THE MERGER

       Since 1990 management of ARBI from time to time received informal
  inquiries from a number of bank holding companies regarding the possibility of
  engaging in a business combination.  Neither the board of directors of ARBI
  nor the holders of a majority of the shares subject to a Stock Restriction
  Agreement dated as of May 18, 1983, which imposes certain limitations on the
  disposition of shares of ARBI Common Stock, initially were interested in
  considering any such proposal.  However, in November 1991, ARBI engaged a
  financial advisor to determine the level of interest in such a combination.
  As a result of the lack of interest generated in such a proposal at that time,
  no further action was taken.

       The Board of Directors of ARBI continued to monitor developments in bank
  acquisitions in New Mexico along with developments in the banking industry
  generally.  As a result of a perceived improvement in the acquisition market
  and the prospect of increased competition from the authorization of branching
  in New Mexico and the increasing possibility of interstate banking, the board
  of directors determined to again investigate the possibility of a business
  combination.  In August 1993, the board met with representatives of Montgomery
  Securities to discuss these matters.  As a result of this meeting, on August
  17, 1993, the Board engaged Montgomery Securities as its financial advisor for
  the purpose of identifying opportunities for the sale of ARBI and
  participating on ARBI's behalf in negotiations resulting from these
  opportunities.

       On August 18, 1993, the Board of Directors of ARBI met with
  representatives of Montgomery Securities to discuss the manner in which
  Montgomery Securities should proceed.  At this meeting it was determined that
  a competitive bidding process would be most likely to obtain the highest offer
  to acquire ARBI.  The Board of Directors authorized Montgomery Securities to
  contact a list of possible acquirors and developed a timetable governing the
  submission of indications of interest and conducting due diligence
  examinations.  Thereafter, Montgomery Securities contacted seven potential
  acquirors to assess their interest in the New Mexico market.  As a result,
  confidentiality agreements were concluded with three institutions and each of
  these companies was provided limited nonpublic information during an initial
  due diligence period.  During the week of March 7, 1994, each of the three
  companies submitted nonbinding indications of interest, subject to the
  completion of due diligence and the negotiation of an acceptable merger
  agreement.  Representatives of Montgomery Securities met with the Board of
  ARBI on March 11, 1994, to consider these indications of interest.  As a
  result, all three companies were invited to conduct on-site due diligence.
  Two of the three companies accepted this invitation.

       The two potential bidders conducted due diligence at the offices of ARBI
  from March 21 through April 18, 1994.  Subsequent to the completion of due
  diligence, but prior to the submission of bids, Montgomery Securities was
  contacted by one of the seven original invitees that had initially declined to
  participate about the possibility of submitting a bid.  This company was
  encouraged to execute a confidentiality agreement as soon as possible and
  commence its due diligence, but it ultimately declined to do so.

                                       21
<PAGE>
 
       In the weeks following the completion of on site due diligence, ARBI and
  its legal counsel attempted to negotiate the terms of definitive merger
  agreements with legal counsel for the two prospective bidders.  Although
  considerable progress was made with both parties, neither party was willing to
  incur the expense of a complete negotiation prior to the completion of the
  auction.  Consequently, on May 9, 1994, final bids were submitted by the two
  companies that had conducted on-site due diligence.  At a meeting of the Board
  of Directors of ARBI on May 12, 1994, representatives of Montgomery Securities
  and ARBI's legal counsel reviewed the two bids in detail, along with the
  status of the contract negotiations with each party and the outstanding issues
  relating thereto.  The Board of ARBI also reviewed the strategic options
  available to it other than a sale of ARBI for stock or cash.  Based on this
  review, the Board considered the acquisition proposals to be more attractive
  to the shareholders of ARBI than the available alternatives.

       Upon the review of the two proposals, each of which was subject to the
  negotiation of a satisfactory definitive merger agreement, it was clear that
  Norwest's proposal, which involved the use of equity securities of Norwest and
  provided for additional consideration to the shareholders by means of the
  distribution of certain assets to the liquidating trust discussed elsewhere
  herein, provided the highest value to the shareholders of ARBI.  The competing
  proposal provided for a lower price per share to be paid in cash in a taxable
  transaction.  After considering the two proposals, including the favorable tax
  treatment associated with the stock-for-stock exchange offered by Norwest and
  the possibility for the realization of additional value by means of the
  ultimate disposition of the assets distributed to the liquidating trust, and
  the oral opinion of Montgomery Securities that the Norwest proposal was fair,
  from a financial point of view, to the shareholders of ARBI, the Board of ARBI
  determined to accept the proposal submitted by Norwest, subject to the
  negotiation of certain changes thereto to provide price protection to the ARBI
  shareholders in the event of a decline in the price of Norwest's common stock
  (a "collar") and certain other changes.  At this meeting, the Board of ARBI
  authorized its management to negotiate the terms of a definitive agreement to
  be submitted to the Board for its consideration.

       During the next several weeks, management of ARBI and its legal counsel
  negotiated the terms of a proposed merger agreement with Norwest.  At a
  meeting held June 4, 1994, the Board of Directors of ARBI considered in detail
  the terms of the Merger Agreement.  The Board also reviewed a draft of a
  fairness opinion which Montgomery Securities was prepared to render regarding
  the financial terms of the transaction.  In reaching its decision to approve
  the terms of the Merger Agreement, the Board of Directors of ARBI considered a
  number of factors, including, without limitation, the following:

       1.  The Board's familiarity with ARBI's business, operations, financial
  condition, earnings, and prospects, and its investigation of similar matters
  concerning Norwest.

       2.  The current and prospective economic environment and competitive
  constraints facing ARBI, including specifically the increasing regulatory
  burdens on small, community based banks and the superior products and services
  which larger competitors can offer to customers.  In this regard, the possible
  effect of then pending legislation to permit interstate banking was also
  considered, as were the cost advantages of larger banks.

       3.  The price to be received by the ARBI shareholders in relation to
  prices recently received by other similarly situated banks, and the relation
  of such price to the Board's view of the value of possible alternatives to the
  Merger, including the range of possible values to the ARBI shareholders of
  such alternatives and the timing and likelihood of actually receiving, and the
  risks associated with seeking to obtain, those values.  In this regard, the
  Board noted that 

                                      22
<PAGE>
 
  the price offered by Norwest was the highest price offered after a nationwide
  search for potential merger partners conducted by Montgomery Securities over
  an extended period of time.

       4.  The financial presentation of Montgomery Securities, ARBI's
  independent financial advisor, at the May 1994 board meeting, the update
  thereof presented by Montgomery Securities at the June 1994 board meeting, and
  the opinion of Montgomery Securities that, as of the date of such opinion, the
  consideration to be received by the ARBI shareholders pursuant to the Merger
  Agreement is fair to such shareholders from a financial point of view.  A copy
  of such opinion, updated through the date of this Proxy Statement-Prospectus,
  is attached hereto as Appendix B and is incorporated herein by reference.  See
  "Fairness Opinion" below.

       5.  The expectation that the receipt of the Norwest Common Stock
  generally will be a tax-free transaction to the ARBI shareholders.

       6.  The potential for the realization of additional value in cash by the
  ARBI shareholders as the result of the ultimate sale of the artwork and
  securities to be distributed to the liquidating trust and the federal income
  tax consequences to the ARBI shareholders as a result thereof.

       7.  The ARBI Board's evaluation of the risks to the consummation of the
  Merger, including the risks associated with obtaining all necessary regulatory
  approvals without the imposition of terms or conditions which would fail to
  satisfy the conditions to the consummation of the Merger.

       8.  The increased liquidity that the Merger would provide to current ARBI
  shareholders.

       9.  The protection afforded to ARBI by the Merger Agreement in the event
  of a decline in the price of the Norwest Common Stock to be issued in the
  merger relative to the prices of the shares of a group of regional bank
  holding companies which the Board believed are generally comparable to
  Norwest.

       In its deliberations, the ARBI Board of Directors did not assign any
  specific weights to these or any other factors.

       THE BOARD OF DIRECTORS OF ARBI UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS
  VOTE FOR THE MERGER.
           

  TERMS OF THE MERGER

      At the Effective Time of the Merger, a wholly owned subsidiary of Norwest
  to be organized as a corporation under New Mexico law ("Merger Co."), will
  merge into ARBI, with ARBI as the surviving corporation, and the outstanding
  shares of ARBI Common Stock (other than shares as to which statutory
  dissenters' rights have been exercised and not forfeited) will be converted
  into a number of shares of Norwest Common Stock determined in accordance with
  the provisions of the Merger Agreement.  The conversion factor, used to
  determine the number of shares of Norwest Common Stock into which each
  outstanding share of ARBI Common Stock will be converted, will be calculated
  by dividing the Adjusted Norwest Shares by the number of shares of ARBI Common
  Stock outstanding.  The "Adjusted Norwest Shares" means the number determined
  by dividing $27,950,000 plus the net proceeds 

                                      23
<PAGE>
 
  (sales price less commissions) from the sale by ARBI, not later than five
  business days prior to the Effective Date of the Merger, of the shares of
  stock of First Security Corporation and Wachovia Corporation held by ARBI as
  investments (the "ARBI Portfolio Stock") by (i) $26.50, if the Norwest
  Measurement Price is equal to or greater than $26.50, (ii) $24.50, if the
  Norwest Measurement Price is equal to or less than $24.50, or (iii) the
  Norwest Measurement Price, if the Norwest Measurement Price is more than
  $24.50 but less than $26.50. The "Norwest Measurement Price" is the average of
  the closing prices of Norwest Common Stock on the NYSE during the period of 20
  trading days ending on the day immediately preceding the Special Meeting.
  Based on the pricing provisions of the Merger Agreement, if the Special
  Meeting had been held on November 1, 1994, assuming no change in the number of
  shares of ARBI Common Stock outstanding and assuming that the proceeds from
  the sale of the ARBI Portfolio Stock were $________, the applicable Norwest
  Measurement Price would have been $__.__ and each share of outstanding ARBI
  Common Stock would be converted into approximately _____ shares of Norwest
  Common Stock. The foregoing information is provided solely for purposes of
  illustration. No assurance can be given concerning the actual conversion
  factor that will apply on the Closing Date.

      The market price for Norwest Common Stock will fluctuate between the date
  of this Proxy Statement-Prospectus and the Effective Date of the Merger, which
  may be a period of several weeks or more, and the Norwest Measurement Price
  will fluctuate accordingly.  As a result, the market value of each share of
  Norwest Common Stock that shareholders of ARBI ultimately receive in the
  Merger could be more or less than its market value on the date of this Proxy
  Statement-Prospectus or the Norwest Measurement Price.  Similarly, the market
  value of the ARBI Portfolio Stock required to be sold prior to the Effective
  Date of the Merger will fluctuate between the date of this Proxy Statement-
  Prospectus.  Accordingly, no assurance can be given as to the net proceeds
  which ultimately may be realized upon the sale of the ARBI Portfolio Stock.

      The Merger Agreement provides that if, between the date of the Merger
  Agreement and the Effective Time of the Merger, shares of Norwest Common Stock
  are changed into a different number or class of shares by reason of any
  reclassification, recapitalization, split-up, combination, exchange of shares,
  readjustment, or similar transaction, or if a stock dividend thereon is
  declared with a record date within the same period, the conversion factor
  provided for in the Merger Agreement will be adjusted accordingly.

      No fractional shares of Norwest Common Stock will be issued in the Merger.
  Instead, Norwest will pay to each holder of ARBI Common Stock who would
  otherwise be entitled to a fractional share an amount of cash equal to the
  fraction of a share of Norwest Common Stock to which the shareholder of ARBI
  would otherwise be entitled multiplied by the average of the closing prices of
  a share of Norwest Common Stock on the NYSE for each of the five trading days
  immediately preceding the Effective Date of the Merger.

      As of the Effective Time of the Merger, each share of the common stock of
  Merger Co. outstanding will be converted into and exchanged for one share of
  common stock of ARBI.  Thereafter, ARBI will be a wholly owned subsidiary of
  Norwest.

      Shares of Norwest Common Stock issued and outstanding immediately prior to
  the Effective Time of the Merger will remain issued and outstanding.

  LIQUIDATING TRUST

      BACKGROUND

      In the course of its operations over past years, ARBI and the Bank have
  acquired an extensive collection of Western art, including original paintings
  and sculptures as well as prints and quality reproductions.  In addition, ARBI
  has also acquired for investment over the years shares of the equity
  securities of certain entities in the financial services business.  As of the
  date of this Proxy Statement-Prospectus, ARBI or the Bank owns shares of
  common stock of First Security Corporation, Wachovia Corporation, and New
  Mexico Financial Corporation.

      In connection with the process by which ARBI solicited bids from potential
  purchasers, Norwest indicated that it was not in a position to acquire the
  artwork or certain investment securities owned by ARBI or the Bank.  As a
  result of negotiations, Norwest and ARBI agreed that the shares of common
  stock of First Security Corporation and Wachovia Corporation owned by ARBI or
  the Bank would be sold prior to the Effective Date of the Merger and the net
  proceeds of such sales added to the purchase price to be paid by Norwest in
  the Merger.  Additionally, ARBI and Norwest agreed that, prior to the
  Effective Date of the Merger, ARBI must distribute the artwork and all shares
  of the common stock of New Mexico Financial Corporation, the holding company
  for Ranchers State Bank, located in Belen, New Mexico, to the ARBI Liquidating
  Trust (the "Trust"), a New Mexico express trust to be formed for the ratable
  benefit of the shareholders of ARBI.  Additionally, in order to defray
  expenses associated with the operation of the Trust, cash in the amount of
  $50,000 will also be distributed to the Trust.  The Trust is also required to
  assume all indebtedness related to the artwork, which as of the date of the
  Proxy Statement-Prospectus totals $20,465. The artwork, securities and cash
  initially distributed to the Trust, and any earnings thereon, are referred to
  herein as the "Trust Assets."

      Pursuant to the terms of the Merger Agreement, the Trust provides that
  from and after the conveyance of the Trust Assets to the Trust, neither ARBI
  nor any ARBI subsidiary will have any rights or obligations with respect to
  the Trust, the Trustee (as defined below) in his official capacity thereof,
  the beneficiaries of the Trust in their capacities as beneficiaries thereof,
  or the assets of the Trust.  Except for liability for corporate taxes payable
  by ARBI or the Bank on the distribution at fair market value of the Trust
  Assets and any related indebtedness assumed by the Trust, ARBI and the Bank
  will have no further liability with respect to the assets and liabilities of
  the Trust after its formation.

      Set forth below is a description of the expected material terms of the
  Trust.  The description below is qualified in its entirety by reference to the
  final trust instrument.

      TERMS OF THE TRUST

      The Trust will be formed immediately prior to the Effective Date of the
  Merger.  The beneficiaries of the Trust will be the shareholders of ARBI
  immediately prior to the Effective Date of the Merger.  On establishment of
  the Trust, each such ARBI shareholders will receive a fractional interest in
  the net assets held in the Trust, equal to the ratio which the number of
  shares of capital stock of ARBI held of record by such shareholder bears to
  the total number of issued and outstanding shares of ARBI Common Stock on such
  date.  Prior to the Effective Date, an individual or institution will be
  selected to serve as trustee (the "Trustee") of the Trust.  The Trustee will
  maintain a ledger reflecting the interest of each former ARBI shareholder in
  the Trust Assets.  Interests in the Trust will be nontransferable, except for
  transfer effected by death, divorce, bankruptcy, or other transfers effected
  by operation of law.

                                      25
<PAGE>
 
      The purpose of the Trust is to receive the initial distribution of the
  Trust Assets; to cause, to the extent practicable, the Trust Assets to be
  converted into cash; to invest cash proceeds from the collection, liquidation,
  or conversion into cash of Trust Assets pending their disposition in
  accordance with the terms of the Trust; to discharge all debts, liabilities,
  and obligations of the Trust; and to distribute, in one or more distributions,
  the remaining Trust Assets to the former ARBI shareholders as promptly as
  practicable.  The Trust will be expressly prohibited from engaging, directly
  or indirectly, in any form of trade or business for profit.

      Pursuant to the terms of the Trust, the Trustee will have broad authority
  to deal with the Trust Assets for the benefit of former ARBI shareholders.
  The Trustee will receive, on behalf of the former ARBI shareholders and for
  their benefit, the Trust Assets from ARBI and the Bank.  The Trustee will be
  authorized to deal with the Trust Assets in any manner the Trustee reasonably
  believes will benefit the former ARBI shareholders, including the sale, lease
  or exhibition of any Trust Asset.  The Trustee will be authorized to collect,
  liquidate, and otherwise convert the Trust Assets into cash and to distribute
  the proceeds thereof, net of expenses, to the former ARBI shareholders.  The
  Trustee may invest and reinvest the Trust Assets and the proceeds received on
  disposition thereof, borrow money for the purposes of the Trust, contest and
  liquidate claims, execute documents of transfer and conveyance, retain
  professional advisors, discharge expenses of the Trust's operations, and file
  all tax and other returns which may be required in connection with the
  operation of the Trust.  The Trustee must keep records of the investments,
  receipts, and disbursements of the Trust, and such records will be available
  for inspection at reasonable times by the former ARBI shareholders.  The
  Trustee will be required to provide an annual accounting to the former ARBI
  shareholders with respect thereto.  The Trustee will be required to
  distribute, at least annually, to the former ARBI shareholders such portion of
  the Trust Assets as may not then be required to be retained for the purposes
  of the Trust.

      In consideration of his services on behalf of the Trust, the Trustee will
  be paid a reasonable fee for his services in equal monthly installments and
  will be reimbursed for reasonable expenses incurred by him for the benefit of
  the Trust.  The Trust will provide that the Trustee will not be personally
  liable with respect to any action taken or omitted to be taken thereunder,
  provided that such action or omission does not constitute gross negligence or
  willful misconduct on the part of the Trustee and that the Trustee at all
  times has exercised good faith in the discharge of his duties.  The Trustee
  will be indemnified by the Trust against any costs and expenses, including
  counsel fees, actually and necessarily incurred in connection with the defense
  of any civil, criminal, administrative, or other claim, action, suit, or
  proceeding in which he may become involved or with which he may be threatened
  by reason of serving as Trustee, and against any payments in settlement of any
  such claim, action, suit, or proceeding or in satisfaction of any related
  judgment, fine, or penalty.

      The Trustee may resign upon giving 30 days' notice in writing to all
  former ARBI shareholders, with such resignation becoming effective upon the
  selection of a successor trustee.  The Trustee may be removed, with or without
  cause, by the written consent of the holders of a majority of the interests in
  the Trust.

      CERTAIN FEDERAL INCOME TAX CONSIDERATIONS RELATED TO THE TRUST

      The Trust is intended to qualify as a "grantor trust" under the rules of
  the Internal Revenue Service.  As such, it may not engage in any trade or
  business for profit, as distinct from the process of liquidating the Trust
  Assets.  A grantor trust is not a tax paying entity under the Internal Revenue
  Code.  Rather, the Trustee, on behalf of the Trust, will file 

                                      26
<PAGE>
 
  information returns with the Internal Revenue Service. Gains or losses
  incurred by the Trust will be reported by the former ARBI shareholders as the
  beneficiaries thereof on their respective personal federal income tax returns.
  The Trustee will distribute to each beneficiary, on an annual basis during the
  Trust's existence, the appropriate Treasury form so that the results of the
  Trust's operations may be reported on the individual tax returns of the
  former ARBI shareholders.

      The receipt by ARBI shareholders of an interest in the Trust will be
  treated as the receipt by them of a dividend of appreciated property from ARBI
  and will be taxable to such shareholders as ordinary income in the year in
  which it is received, whether or not any cash is actually distributed to the
  shareholders in respect of the liquidation of assets of the Trust during that
  year.  Accordingly, the receipt of the interest in the Trust may result in a
  tax liability to the former ARBI shareholders under circumstances in which no
  cash has been distributed to them in order to pay the tax due.  For any ARBI
  shareholder, the taxable value of the interest in the Trust received by such
  shareholder will be equal to such shareholder's pro rata share of the fair
  market value of the property distributed to the Trust.  Although ARBI intends,
  prior to the distribution of the Trust Assets to the Trust, to obtain an
  appraisal of the artwork included therein, no assurance may be given that the
  Internal Revenue Service will concur in such valuation.

      During the time the Trust is in existence, the Trustee will dispose of the
  Trust Assets.  To the extent that Trust Assets are disposed of at prices in
  excess of the fair market value thereof at the time such assets were received
  by the Trust and the Trust interests were distributed to the ARBI
  shareholders, the Trust will recognize gain in the amount of such excess.  If
  the proceeds from the sale of the Trust assets are less than the fair market
  value of such assets as of the date the Trust interests were distributed to
  the ARBI shareholders, each holder of a Trust interest will recognize a loss
  equal to the amount of such difference.  Assuming that each holder of a Trust
  interest holds such interest for investment purposes, this gain or loss will
  be characterized as capital gain or loss.

      As indicated above, although the purpose of the Trust is to sell the Trust
  Assets and distribute the proceeds thereof to the former ARBI shareholders,
  the terms of the Trust give the Trustee substantial discretion with respect to
  the timing of such sales and distributions. Accordingly, no assurance may be
  given that the Trustee will distribute the proceeds of any sale giving rise to
  a taxable gain in time for the former ARBI shareholders to pay the federal
  income tax due in respect of such distribution. In such event, the former ARBI
  shareholders may incur tax liability as a result of the actions of the Trustee
  and not receive the funds necessary to pay such tax liability.

  FAIRNESS OPINION

       Pursuant to an engagement letter dated August 17, 1993, ARBI retained
  Montgomery Securities ("Montgomery") to act as its financial advisor for the
  purpose of identifying opportunities for the sale of ARBI, advising ARBI
  concerning opportunities for the sale of ARBI and, if requested, participating
  on ARBI's behalf in negotiations resulting from these opportunities.
  Montgomery is a nationally recognized firm and, as part of its investment
  banking activities, is regularly engaged in the valuation of businesses and
  their securities in connection with merger transactions and other types of
  acquisitions, negotiated underwritings, competitive biddings, secondary
  distributions of listed and unlisted securities, private placements, and
  valuations for corporate and other purposes.  ARBI selected Montgomery as its
  financial advisor on the basis of its experience and expertise in transactions
  similar to the Merger and its reputation in the banking and investment
  communities.

                                      27
<PAGE>
 
       At the May 12, 1994, meeting of ARBI's Board of Directors, Montgomery
  delivered its oral opinion, subsequently confirmed in writing both as of June
  6, 1994, and as of the date of this Proxy Statement-Prospectus, that the
  consideration to be received by ARBI's shareholders in the Merger is fair to
  ARBI's shareholders from a financial point of view as of such dates.  No
  limitations were imposed by ARBI on Montgomery with respect to the
  investigations made or procedures followed in rendering its opinion.  THE FULL
  TEXT OF MONTGOMERY'S WRITTEN OPINION TO ARBI'S BOARD OF DIRECTORS IS ATTACHED
  HERETO AS APPENDIX B AND IS INCORPORATED HEREIN BY REFERENCE AND SHOULD BE
  READ CAREFULLY AND IN ITS ENTIRETY IN CONNECTION WITH THIS PROXY STATEMENT-
  PROSPECTUS.  THE FOLLOWING SUMMARY OF MONTGOMERY'S OPINION IS QUALIFIED IN ITS
  ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE OPINION.  MONTGOMERY'S OPINION
  DOES NOT CONSTITUTE A REPORT OR VALUATION WITHIN THE MEANING OF SECTION 11 OF
  THE SECURITIES ACT OF 1933 (THE "SECURITIES ACT") AND SHOULD NOT BE ACCORDED
  THE DEGREE OF RELIANCE PLACED ON SUCH REPORTS AND VALUATIONS.  MONTGOMERY HAS
  NOT ASSUMED RESPONSIBILITY FOR PERFORMING THE LEVEL OF DILIGENCE OR
  INDEPENDENT VERIFICATION THAT WOULD BE REQUIRED FOR IT TO RENDER A REPORT OR
  VALUATION FOR PURPOSES OF THE SECURITIES ACT.  MONTGOMERY'S OPINION IS
  ADDRESSED TO ARBI'S BOARD OF DIRECTORS ONLY AND DOES NOT CONSTITUTE A
  RECOMMENDATION TO ANY ARBI SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE
  AT THE SPECIAL MEETING.

       In connection with its opinion, Montgomery, among other things:  (i)
  reviewed certain publicly available financial and other data with respect to
  ARBI and Norwest including their respective consolidated financial statements
  for recent years and the interim period to March 31, 1994, and certain other
  relevant financial and operating data relating to ARBI and Norwest made
  available to Montgomery from published sources and from the internal records
  of ARBI; (ii) reviewed the Merger Agreement; (iii) reviewed certain historical
  market prices and trading volumes of Norwest Common Stock as reported by the
  New York Stock Exchange; (iv) compared ARBI and Norwest from a financial point
  of view with certain other companies in the banking industry that Montgomery
  deemed to be relevant; (v) considered the financial terms, to the extent
  publicly available, of selected recent business combinations of companies in
  the banking industry that Montgomery deemed to be comparable, in whole or in
  part, to the Merger; (vi) reviewed and discussed with representatives of the
  management of ARBI and Norwest certain information of a business and financial
  nature regarding ARBI and Norwest, furnished to Montgomery by ARBI and
  Norwest, including financial forecasts and related assumptions of ARBI; (vii)
  reviewed and discussed with representatives of the management of ARBI the
  September 26, 1991, appraisal obtained by ARBI of certain assets being
  distributed to the Trust by ARBI; (viii) made inquiries regarding and
  discussed the Merger and the Merger Agreement and other matters related
  thereto with ARBI's counsel; and (ix) performed such other analyses and
  examinations as Montgomery deemed appropriate.

       In connection with its review, Montgomery did not assume any
  responsibility for the independent verification of any of the foregoing
  information with respect to ARBI or Norwest, and relied on all such
  information and assumed all such information was complete and accurate in all
  material respects.  With respect to the financial forecasts for ARBI provided
  to Montgomery by ARBI's management, Montgomery assumed for purposes of its
  opinion that they were reasonably prepared on bases reflecting the best
  available estimates and judgments of ARBI's management at the time of
  preparation as to the future financial performance of ARBI and that they
  provided a reasonable basis upon which Montgomery could form its opinion.
  With respect to the appraisal obtained by ARBI of certain assets being
  distributed to the Trust by ARBI, Montgomery assumed for purposes of its
  opinion that the appraisal reflected a reasonable estimate as to the amount
  realizable by the Trust upon liquidation of such assets.  Montgomery also
  assumed that there were no material changes in ARBI's or Norwest's assets,
  financial condition, results of operations, business, or prospects since the
  dates of their last financial statements made available to 

                                      28
<PAGE>
 
  Montgomery. Montgomery relied on advice of counsel to ARBI as to all legal
  matters with respect to ARBI, the Merger, the Proxy Statement-Prospectus, and
  the Merger Agreement. Montgomery is not expert in the evaluation of loan
  portfolios for purposes of assessing the adequacy of the allowance for losses
  with respect thereto and assumed that such allowances for each of ARBI and
  Norwest were in the aggregate adequate to cover such losses. In addition,
  Montgomery did not assume any responsibility for reviewing any individual
  credit files or making an independent evaluation, appraisal or physical
  inspection of the assets or individual properties of ARBI or Norwest. Further,
  Montgomery's opinion was based on economic, monetary and market conditions
  existing on, and the information made available to Montgomery as of, the date
  thereof and on the assumption that the Merger would be consummated in
  accordance with the terms of the Merger Agreement, without any amendment
  thereto and without any waiver of the conditions therein.

       Set forth below is a brief summary of the report presented by Montgomery
  to ARBI's Board of Directors on May 12, 1994, in connection with its oral
  opinion.  The summary set forth below does not purport to be a complete
  description of the presentation by Montgomery to ARBI's Board of Directors or
  of the analyses performed by Montgomery.  The preparation of a fairness
  opinion necessarily is not susceptible to partial analysis or summary
  description.  Montgomery believes that its analyses and the summary set forth
  below must be considered as a whole and that selecting portions of its
  analyses and of the factors considered, without considering all analyses and
  factors, would create an incomplete view of the process underlying the
  analyses set forth in its presentation to ARBI's Board of Directors.  In
  addition, Montgomery may have given various analyses more or less weight than
  other analyses, and may have deemed various assumptions more or less probable
  than other assumptions, so that the ranges of valuations resulting from any
  particular analysis described above should not be taken to be Montgomery's
  view of the actual value of ARBI or the combined company.  The fact that any
  specific analysis has been referred to in the summary below is not meant to
  indicate that such analysis was given greater weight than any other analysis.

       In performing its analyses, Montgomery made numerous assumptions with
  respect to industry performance, general business and economic conditions and
  other matters, many of which are beyond the control of ARBI and Norwest.  The
  analyses performed by Montgomery are not necessarily indicative of actual
  values or actual future results, which may be significantly more or less
  favorable than suggested by such analyses.  Such analyses were prepared solely
  as part of Montgomery's analysis of the fairness of the Merger to ARBI
  shareholders and were provided to ARBI's Board of Directors in connection with
  the delivery of Montgomery's opinion.  The analyses do not purport to be
  appraisals or to reflect the prices at which a company might actually be sold
  or the prices at which any securities may trade at the present time or at any
  time in the future.  Montgomery used in its analyses various projections of
  future performance prepared by the management of ARBI.  The projections are
  based on numerous variables and assumptions which are inherently unpredictable
  and must be considered not certain of occurrence as projected.  Accordingly,
  actual results could vary significantly from those set forth in such
  projections.

       As described above, Montgomery's opinion and presentation to ARBI's Board
  of Directors were among the many factors taken into consideration by ARBI's
  Board of Directors in making its determination to approve the Merger.

       ANALYSIS OF SELECTED BANK MERGER TRANSACTIONS

       Montgomery reviewed the consideration paid in recently announced
  transactions whereby certain banks were acquired.  Specifically, Montgomery
  reviewed 148 transactions announced since January 1990 involving acquisitions
  of banks in the Southwest (Arizona, Colorado, New Mexico, Nevada, Texas, Utah,
  and Wyoming) (the "Southwest Bank Mergers"), and nine 

                                      29
<PAGE>
 
  transactions announced since January 1990 involving acquisitions of banks in
  New Mexico (the "New Mexico Bank Mergers").

       For each such transaction Montgomery calculated, among other things, the
  ratio of premium (price in excess of tangible book value) to core deposits,
  price to book value, price to last twelve-months' ("LTM") earnings, and price
  to total deposits.  The calculations for the Southwest Bank Mergers and the
  New Mexico Bank Mergers yielded (i) a median percentage of premium to core
  deposits of 3.66% and 1.40%, respectively, (ii) a ratio of price to book value
  of 1.40 and 1.15, respectively, (iii) a ratio of price to LTM earnings of 11.8
  and 13.8, respectively, and (iv) a ratio of price to total deposits of 11.96%
  and 11.48%, respectively.  In comparison, assuming that the total
  consideration payable in the Merger equals $31.9 million, of which
  approximately $3.9 million is attributable to the sale of the ARBI Portfolio
  Stock and the sale of the Trust Assets being distributed to the Trust,
  Montgomery determined that the consideration to be paid to ARBI shareholders
  in the Merger represented a percentage of premium to core deposits of 5.74%, a
  ratio of price to book value of 1.59, a ratio of price to LTM earnings of
  14.2, and a ratio of price to total deposits of 16.47%.

       No other company or transaction used in the above analysis as a
  comparison is identical to ARBI or the Merger.  Accordingly, an analysis of
  the results of the foregoing is not mathematical; rather, it involves complex
  considerations and judgments concerning differences in financial and operating
  characteristics of the companies and other factors that could affect the
  public trading value of the companies to which ARBI and the Merger are being
  compared.

       CONTRIBUTION ANALYSIS

       Montgomery analyzed the contribution of each of ARBI and Norwest to,
  among other things, total equity and net income of the pro forma combined
  company for the year ended December 31, 1993, and for the three-month period
  ended March 31, 1994.  This analysis showed, among other things, that based on
  pro forma combined balance sheets and income statements for ARBI and Norwest
  as of and for the year ended December 31, 1993, and as of and for the three-
  month period ended March 31, 1994, ARBI would have contributed 0.50% and
  0.54%, respectively, of the total equity and 0.42% and 0.27%, respectively, of
  the net income of the combined company.  Assuming the total consideration
  payable in the Merger equals $31.9 million, ARBI shareholders would own 0.40%
  of the combined company.

       PRESENT VALUE ANALYSIS

       In performing the present value analysis, Montgomery assumed that the
  Merger was consummated as of January 1, 1994, on the basis of an exchange
  ratio of 2.691 shares of Norwest Common Stock for each share of ARBI Common
  Stock.  Montgomery calculated the 2.691 exchange ratio by excluding the $3.9
  million of consideration attributable to ARBI's sale of the ARBI Portfolio
  Stock and the Trust's sale of the Trust Assets from the total consideration
  being paid in the Merger.  In performing the analysis, Montgomery estimated
  the present value of the future streams of annual pre-tax dividend income that
  the combined company could produce over a five-year period under various
  assumptions.  One such assumption was that the proceeds from the anticipated
  sales of the ARBI Portfolio Stock and the Trust Assets by ARBI and the Trust,
  respectively, were paid out as a dividend in the first year.  Montgomery then
  estimated the terminal value of 2.691 shares of the combined company at the
  end of the five-year period by applying various multiples (ranging from 10x to
  14x) to the combined company's projected 1998 earnings.  Montgomery then added
  the dividend stream to each of the terminal values and discounted the sums
  using a 10% discount rate.  This present value analysis indicated a reference
  range of between $79.06 and $103.52 per 2.691 shares of Norwest Common Stock.
  In comparison, Montgomery 

                                      30
<PAGE>
 
  noted that, if ARBI were to remain independent, based on the sum of the
  present value of the future stream of annual pretax dividend income that ARBI
  could produce over a five-year period and certain terminal values derived from
  applying multiples ranging from 8x to 12x to ARBI's projected 1998 earnings,
  and discounting such sums using a 14% discount rate (reflecting the higher
  risks associated with remaining an independent community bank), the present
  value of one share of ARBI Common Stock ranged between $47.80 and $67.96.

       ANALYSIS OF IMPACT ON ARBI SHAREHOLDERS

       Based on forecasts of ARBI's and Norwest's financial results and other
  information, Montgomery calculated the earnings, book value and dividends for
  the pro forma combined company per 2.691 shares of ARBI Common Stock, without
  taking into account the $3.9 million of consideration attributable to ARBI's
  sale of ARBI Portfolio Stock and the Trust's sale of the Trust Assets.  The
  calculations indicated that the pro forma combined company's 1994 earnings per
  2.691 shares of Norwest Common Stock were 15.1% greater than the earnings per
  share projected for such period for ARBI.  The calculations also showed that
  the combined company's book value as of March 31, 1994, per 2.691 shares of
  Norwest Common Stock was approximately 40.8% less than ARBI's book value per
  share as of such date, and that the combined company's dividends per 2.691
  shares of Norwest Common Stock were 99% greater than the then current
  dividends per share of ARBI.

       COMPARABLE COMPANY ANALYSIS

       Using public and other available information, Montgomery compared certain
  financial ratios of ARBI and Norwest (including equity to assets, return on
  average assets, and return on average equity) and certain credit ratios of
  ARBI and Norwest as of December 31, 1993, to 24 other banks in New Mexico, in
  ARBI's case, and the top 50 commercial banking companies as measured in terms
  of assets (the "Top 50") and the 41 non-money center companies included in
  such Top 50 (the "Regional Banks"), in Norwest's case.  No company used in the
  analysis is identical to ARBI.  The analysis necessarily involved complex
  considerations and judgments concerning differences in financial and operating
  characteristics of the companies.  Some of these commercial banking companies
  are included in Montgomery's Quarterly Bank Monitor, a research publication
  that tracks 50 banking companies nationally.

       RATIO ANALYSIS

       Montgomery analyzed certain financial and credit ratios of ARBI, Norwest,
  and the pro forma combined company, including return on average assets, return
  on average equity, common equity to assets, non-performing assets to average
  assets and to total loans, and loan loss reserves to non-performing assets and
  total loans, assuming the Merger was accounted for as a pooling of interests
  and without taking into account any synergies that might be realized upon
  consummation of the Merger.  Such analyses indicated that, with the exception
  of the ratio of common equity to assets, the combined company would be
  stronger in each category than ARBI on a stand-alone basis.  Montgomery
  calculated that the Merger would produce a pro forma ratio of common equity to
  assets of 6.35% compared to a ratio of 9.38% for ARBI on a stand-alone basis
  at March 31, 1994.

       HISTORICAL COMMON STOCK PRICE, VOLUME, AND OTHER STUDIES

       Montgomery reviewed the historical common stock prices and volume history
  of Norwest.  In addition, Montgomery reviewed Norwest's earnings per share,
  price to book value, price to

                                       31
<PAGE>
 
  earnings, and dividend yield histories.  Montgomery also compared the price
  and earnings per share of Norwest Common Stock from May 12, 1989, through May
  6, 1994, to a bank industry proxy consisting of the 33 commercial banking
  companies followed by Montgomery and the Standard & Poor's 500.

       COMPENSATION

       Pursuant to a letter agreement dated August 17, 1993 (the "Engagement
  Letter"), ARBI engaged Montgomery to act as its financial advisor in
  connection with a possible sale of ARBI.  ARBI has paid Montgomery $150,000 to
  date for its services pursuant to the terms of the Engagement Letter.  ARBI
  has also agreed to pay Montgomery, upon consummation of the Merger, a fee
  equal to 1.5% of the total consideration payable in the Merger, but in no
  event less than $250,000.  The $150,000 paid by ARBI to date is to be credited
  against the amount owing upon consummation of the Merger.  ARBI also has
  agreed to reimburse Montgomery for its reasonable out-of-pocket expenses.
  Pursuant to a separate letter agreement, ARBI has agreed to indemnify
  Montgomery, its affiliates, and their respective partners, directors,
  officers, agents, consultants, employees, and controlling persons against
  certain liabilities, including liabilities under the federal securities laws.

       In the ordinary course of its business, Montgomery actively trades equity
  securities of Norwest for its own account and for the accounts of customers
  and, accordingly, may at any time hold a long or short position in such
  securities.  Certain partners of Montgomery also own shares of Norwest Common
  Stock.

  EFFECTIVE DATE AND TIME OF THE MERGER

      Subject to the terms and conditions of the Merger Agreement, the Effective
  Date of the Merger will be the date on which executed Articles of Merger are
  filed with the Secretary of State of the State of New Mexico.  Such filing
  will be made five business days following the satisfaction or waiver of all
  conditions of the Merger Agreement or on such other date upon which the
  parties agree, and the time at which such filing will be made is hereinafter
  referred to as the "Time of Filing."  The "Effective Time of the Merger" will
  be 11:59 p.m., New Mexico time, on the Effective Date of the Merger.  Norwest
  and ARBI anticipate that the closing will occur as soon as possible after the
  Special Meeting.  See "Terms of the Merger," "Conditions to the Merger," and
  "Regulatory Approvals."

  SURRENDER OF CERTIFICATES

      As soon as practicable after 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 former holder of record
  of shares of ARBI 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.

      SHAREHOLDERS OF ARBI 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 ARBI
  Common Stock, together with a properly completed letter of transmittal, there
  will be issued and mailed to the holder a certificate representing the number
  of whole shares of Norwest Common Stock to which such holder is entitled and,
  where applicable, a check for the amount representing any 

                                       32
<PAGE>
 
  fractional share. A certificate for Norwest Common Stock may be issued in a
  name other than the name in which the surrendered certificate is registered
  only if (i) the certificate surrendered is properly endorsed and otherwise in
  proper form for transfer and (ii) the person requesting the issuance of such
  certificate either pays to the Exchange Agent any transfer or other taxes
  required by reason of the issuance of a certificate for such shares in a name
  other than the registered holder of the certificate surrendered or establishes
  to the satisfaction of the Exchange Agent that such tax has been paid or is
  not applicable.

      All Norwest Common Stock issued pursuant to the 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 ARBI entitled to receive
  certificates for shares of Norwest Common Stock until such shareholders
  surrender their certificates representing shares of ARBI 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.

  CONDITIONS TO THE MERGER

      The Merger will occur only if the Merger Agreement is approved by the
  requisite vote of the holders of ARBI Common Stock.  Consummation of the

  date of such financial statements; (iv) the requirement that ARBI and its
  subsidiaries considered as a whole shall not have sustained since March 31,
  1994, any material loss or interference with their business from any civil
  disturbance or any fire, explosion, flood, or other calamity, whether or not
  covered by insurance; (v) the absence of any reasonable basis for any
  proceeding, claim, or action of any nature seeking to impose, or that could
  reasonably be expected to result in the imposition, on ARBI or any of its
  subsidiaries of any liability related to the release of hazardous substances
  as defined under any local, state, or federal environmental statute,
  regulation, or ordinance which has had or could reasonably be expected to have
  a material adverse effect upon ARBI and its subsidiaries taken as a whole;
  (vi) the absence, since March 31, 1994, of any change, other than changes in
  banking laws or regulations that affect the banking industry generally or

  financial condition, results of operations, business, or prospects of ARBI and
  its subsidiaries taken as a whole; (vii) the termination of a Stock
  Restriction Agreement, dated as of May 18, 1983, to which certain ARBI
  shareholders are a party; and (viii) the delivery to Norwest by ARBI at the

  of all of ARBI's subsidiaries free and clear of any lien, claim, charge,
  option, encumbrance, or agreement with respect thereto.

  REGULATORY APPROVALS

      Transactions such as the Merger are subject to prior approval by the
  Federal Reserve Board under Sections 3 and 4 of the Bank Holding Company Act
  of 1956, as amended (the "BHC Act"), which requires that the Federal Reserve
  Board take into consideration the financial and managerial resources and
  future prospects of the existing and proposed institutions and the convenience
  and needs of the communities to be served.  By letter dated October 7, 1994,
  the Federal Reserve Bank informed Norwest that it had approved the Merger.

      As required by New Mexico law, Norwest notified the Director of the
  Financial Institutions Division of the New Mexico Regulation and Licensing
  Department of its intent to acquire ARBI.  By letter dated August 31, 1994,
  the Financial Institutions Division informed Norwest that it had no objection
  to the proposed acquisition.

      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 ARBI are not aware of any governmental approvals or compliance
  with banking laws and regulations that are required for consummation of the
  Merger other than those described above.  Should any other approval or action
  be required, it is presently contemplated that such approval or action would
  be sought.  There can be no assurance that any such approval or action, if
  needed, could be obtained and, if such approvals or actions are obtained,
  there can be no assurance as to the timing thereof.  The Merger cannot proceed
  in 

                                       34
<PAGE>
 
  the absence of all requisite regulatory approvals. See "Conditions to the
  Merger," "Effective Date and Time of the Merger," and "Waiver, Amendment, and
  Termination."

  CONDUCT OF BUSINESS PENDING THE MERGER

      Under the Merger Agreement, each of ARBI and its subsidiaries is obligated
  to maintain the general character of its business and conduct its business in
  the ordinary and usual manner; and Norwest is obligated to conduct and to
  cause its subsidiaries to conduct their respective businesses in compliance
  with all material obligations and duties imposed by laws, regulations, rules,
  and ordinances, and by judicial orders, judgments, and decrees applicable to
  them, their businesses, or their properties.

  CERTAIN COVENANTS

      Pursuant to the Merger Agrement, ARBI and Norwest have each agreed (i) to
  furnish all information required for inclusion in the Registration Statement
  to be filed with the Securities and Exchange Commission (the "SEC") and the
  proxy statement or statements included therein and in any statement or
  application to any governmental body in connection with the transactions
  contemplated by the Merger Agreement; (ii) to take all necessary corporate and
  other action to obtain all regulatory approvals, consents, and other approvals
  required to carry out the transactions contemplated by the Merger Agreement
  and to cooperate with the other party in obtaining such approvals; (iii) to

  and its subsidiaries furnished in connection with the transactions furnished
  by the Merger Agreement and not to release or disclose such information,
  except as required by law or to outside professional advisers; and (iv) to
  consult with each other concerning the form and substance of any press release
  or public disclosure of matters related to the Merger Agreement and
  transactions contemplated thereby.

      The Merger Agreement includes a number of covenants of ARBI which are
  customary in transactions such as the Merger.  Such covenants include, but are
  not limited to, the following:  ARBI and each of its subsidiaries will
  maintain its corporate existence in good standing; extend credit in accordance
  with existing lending policies, except that it shall not, without the prior
  written consent of Norwest, make any new loan or modify, restructure, or renew
  any existing loan, except pursuant to commitments made prior to June 6, 1994,
  to any borrower if the amount of the resulting loan, when aggregated with all
  other loans or extensions of credit to such person, would be in excess of
  $200,000; maintain proper business and accounting records in accordance with
  generally accepted principles; maintain its properties in good repair and
  condition, ordinary wear and tear excepted; maintain in all material respects
  presently existing insurance coverage; use its best efforts to preserve its

  leases and other contracts in effect following the Merger; comply in all
  material respects with all laws, regulations, ordinances, codes, orders,
  licenses, and permits applicable to the properties and operations of ARBI and
  each of its subsidiaries the noncompliance with which reasonably could be
  expected to have a material adverse effect on ARBI and its subsidiaries taken
  as a whole; and permit Norwest and its representatives to examine its and its
  subsidiaries' books, records, and properties, and to interview officers,
  employees, and agents at all reasonable times when it is open for business.
  The Merger Agreement also provides that, prior to the Closing Date, neither
  ARBI nor any of its subsidiaries may, without the prior written consent of
  Norwest:  (i) amend or otherwise change its articles of incorporation or
  association or bylaws; (ii) issue or sell, or authorize for issuance or sale,
  or grant any options or make other agreements with 

                                       35

  course of business for terms of up to one year and in amounts of $100,000 or
  less; (vii) amend or terminate any "employee benefit plan" within the meaning
  of the Employee Retirement Income Security Act of 1974, as amended, except as
  required by law; (viii) make any contributions to any such plan except as
  required by the terms of such plan in effect as of June 6, 1994; (ix) declare,
  set aside, make, or pay any dividend or other distribution with respect to its
  capital stock, except any dividend declared by a subsidiary's Board of
  Directors in accordance with applicable law and regulation and except for a
  regular quarterly cash dividend on ARBI Common Stock of not more than $0.25
  per share for the third and fourth quarters of 1994 and, if the Effective Time
  of the Merger is after March 31, 1995, the first quarter of 1995; (x) redeem,
  purchase, or otherwise acquire, directly or indirectly, any of the capital
  stock of ARBI; (xi) increase the compensation of any officers, directors, or
  executive employees, except pursuant to existing compensation plans and
  practices and except that ARBI or the Bank may pay an aggregate of $150,000 in
  bonuses to persons who, on the day before the Effective Date of the Merger,
  are employees of ARBI or the Bank; (xii) sell or otherwise dispose of any
  shares of the capital stock of any subsidiary; or (xiii) sell or otherwise
  dispose of any of its assets or properties other than in the ordinary course
  of business. In addition, ARBI has agreed to (i) deliver resale letters from
  its affiliates under Rule 145 of the SEC; (ii) establish additional such
  accruals and reserves as necessary to conform ARBI's accounting and credit
  loss practices to those of Norwest; (iii) deliver environmental assessment

  entire interest in El Pueblo Properties; (ix) sell all of the ARBI Portfolio
  Stock; and (x) prepay certain indebtedness secured by stock of the Bank.
  Neither ARBI nor the Bank, nor any director, officer, representative, or agent
  thereof, will, directly or indirectly, solicit, authorize the solicitation of,
  or enter into any discussions with any corporation, partnership, person, or
  other entity or group (other than Norwest) concerning any offer or possible
  offer (i) to purchase any shares of ARBI Common Stock, any option or warrant
  to purchase any shares of ARBI Common Stock, any securities convertible into
  any shares of ARBI Common Stock, or any other equity security of ARBI or any
  of its subsidiaries; (ii) to make a tender or exchange offer for any shares of
  ARBI Common Stock or other equity security; (iii) to purchase, lease, or
  otherwise acquire the assets of ARBI or any of its subsidiaries, except in the
  ordinary course of business; or (iv) to merge, consolidate, or otherwise
  combine with ARBI or any of its subsidiaries. Any offer or inquiry to ARBI or
  any of its subsidiaries concerning any of the foregoing must be promptly
  disclosed, along with the terms thereof, to Norwest.

      The Merger Agreement includes a number of covenants of Norwest which are
  customary in transactions such as the Merger.  In addition, pursuant to the
  Merger Agreement Norwest has agreed to (i) give ARBI written notice of the
  receipt of all regulatory approvals; (ii) permit ARBI and its representative
  to examine Norwest's books, records, and properties, and to interview
  Norwest's officers, employees, and agents, for a period of up to 15 days prior
  to the Closing Date; (iii) loan to ARBI funds sufficient to enable ARBI to pay
  in full all indebtedness of ARBI secured by the stock of any of its
  subsidiaries; (iv) use all reasonable efforts to 

                                       36
<PAGE>
 
  maintain, for three years following the Effective Time of the Merger,
  directors' and officers' liability insurance for future claims arising out of
  occurrrences prior to the Effective Time of the Merger; (v) deposit with the
  Exchange Agent, prior to the Effective Time of the Merger, the shares of
  Norwest Common Stock and the cash in lieu of fractional shares to be issued to
  shareholders of ARBI at Closing; (vi) deliver to ARBI, from the date of the
  Merger Agreement to the Effective Date of the Merger, any quarterly and annual
  reports file by Norwest with the SEC; and (vii) file with the SEC such reports
  as Norwest is otherwise required to file necessary to permit shareholders of
  ARBI who may be deemed affiliates of ARBI to sell the Norwest Common Stock
  they receive in the Merger pursuant to Rule 145.

  WAIVER, AMENDMENT, AND TERMINATION

      The parties may, in writing, give any consent, take any action with
  respect to termination of the Merger Agreement, or waive any inaccuracies in
  the representations and warranties of the other party or compliance by the
  other party with any of the covenants and conditions in the Merger Agreement.

      At any time before the Time of Filing the parties may amend the Merger
  Agreement by action of their respective Boards of Directors or pursuant to
  authority delegated by their respective Boards of Directors; provided,
  however, that no such amendment occurring after approval of the Merger by ARBI
  shareholders may adversely affect the consideration to be received by ARBI
  shareholders.

      The Merger Agreement provides that it may be terminated at any time prior
  to the Time of Filing (i) by mutual written consent of the parties; (ii) by
  either party by written notice to the other if the Merger shall not have been
  consummated by May 15, 1995, unless such failure of consummation is due to the
  failure of the party seeking termination to perform or observe in all material
  respects the covenants and agreements to be performed or observed by it under
  the Merger Agreement; (iii) by either party by written notice to the other if
  any court or governmental authority of competent jurisdiction shall have
  issued a final order restraining, enjoining, or otherwise prohibiting the
  consummation of the transactions contemplated by the Merger Agreement; or (iv)
  by ARBI, within 5 days after the end of the period of 20 trading days used in
  the calculation of Norwest Measurement Price if (A) the Norwest Measurement
  Price is less than $20.00 and (B) the quotient obtained by dividing the
  Norwest Measurement Price by $27.25 is less than 85% of the quotient obtained
  by dividing (x) the weighted average closing prices per share of the common
  stock of each company in a group of 23 regional bank holding companies (the
  "Index Group") over such period of 20 trading days by (y) the weighted average
  closing prices per share of the common stock of each company in the Index
  Group on June 3, 1994.

  MANAGEMENT AND OPERATIONS AFTER THE MERGER

      As of the Effective Time of the Merger, ARBI will become a subsidiary of
  Norwest and the Bank will become an indirect subsidiary of Norwest.  As soon
  as possible after the Closing, management of Norwest plans to merge the Bank
  into Norwest Bank New Mexico, N.A. and to consolidate the Bank's branch in
  Moriarty and the existing branch of Norwest Bank New Mexico, N.A. in Moriarty.
  After the Closing, with the exception of the consolidation of the Moriarty
  branches, the Bank will continue to operate at its present locations,
  providing products and services offered by Norwest affiliates.  See "Terms of
  the Merger."

  CERTAIN DIFFERENCES IN RIGHTS OF SHAREHOLDERS

      ARBI is incorporated as a corporation under the laws of New Mexico, and
  Norwest is incorporated as a corporation under the laws of Delaware.
  Shareholders of ARBI, whose rights are governed by ARBI's Articles of
  Incorporation and Bylaws and by the New Mexico Business Corporation Act (the
  "NMBCA"), will, upon consummation of the Merger, become stockholders of
  Norwest.  The rights of former shareholders of ARBI will then be governed by
  Norwest's Certificate of Incorporation and By-Laws and by the Delaware General
  Corporation Law (the "DGCL").  The following is a summary of certain
  significant differences between the rights of shareholders of ARBI and
  stockholders of Norwest.

      CAPITAL STOCK

      ARBI.  ARBI's Articles of Incorporation authorize the issuance of
  1,000,000 shares of common stock, par value $1.00 per share, and 1,000,000
  shares of cumulative preferred stock, par value $1.00 per share.  At June 30,
  1994, 410,095 shares of ARBI Common Stock were issued and outstanding.
  Although shares of ARBI's cumulative preferred stock are issuable in series by
  action of the Board of Directors, no shares of ARBI's preferred stock are
  issued and outstanding as of the date of this Proxy Statement-Prospectus.
  Accordingly, no class or series has any preference over the ARBI Common Stock
  with respect to dividends and distributions upon the liquidation of ARBI.

      NORWEST.  Norwest's Certificate of Incorporation authorizes the issuance
  of 500,000,000 shares of Common Stock, par value $1 2/3 per share, and
  5,000,000 shares of preferred stock, without par value ("Preferred Stock").
  At June 30, 1994, 323,084,474 shares of Common Stock were issued, of which
  315,457,227 were outstanding and 7,627,247 were held as treasury shares, and
  2,306,000 shares of Preferred Stock were outstanding consisting of 1,127,125
  shares of 10.24% Cumulative Preferred Stock, 1,143,750 shares of Cumulative
  Convertible Preferred Stock, Series B, and 35,125 shares of ESOP Cumulative
  Convertible Preferred Stock.  In addition, 1,000,000 shares of Preferred Stock
  are reserved for issuance under the Rights Agreement dated as of November 22,
  1988, between Citibank, N.A. as Rights Agent, and Norwest (the "Rights
  Agreement").  Norwest has also authorized for issuance from time to time and
  registered with the Commission an additional 1,700,000 shares of Preferred
  Stock.  Norwest has also authorized for issuance from time to time and
  registered with the SEC pursuant to two universal shelf registration
  statements, an indeterminate number of securities (the "Shelf Securities")
  with an aggregate initial offering price not to exceed $2,225,000,000.  The
  Shelf Securities may be issued as Preferred Stock or as securities convertible
  into shares of Preferred Stock or Common Stock.  Based on the current number
  of shares of Preferred Stock and Common Stock authorized for issuance under
  Norwest's Certificate of Incorporation, the maximum number of shares of
  Preferred Stock and Common Stock, respectively, that could be issued pursuant
  to the effective shelf registration statements, when added to shares of
  Preferred Stock and Common Stock already reserved for issuance, issued, or
  outstanding, could not exceed respectively, 5,000,000 shares of Preferred
  Stock and 500,000,000 shares of Common Stock.  All or any portion of the
  authorized but unissued Preferred Stock or Shelf Securities issuable as
  Preferred Stock or convertible into Preferred Stock or Common Stock, may be
  issued by the Board of Directors of Norwest without further action by
  stockholders.  Holders of Preferred Stock have certain rights and preferences
  with respect to dividends and upon liquidation that are superior to those of
  holders of Common Stock.  The relative rights and preferences of any Preferred
  Stock issued in the future may be established by Norwest's Board of Directors
  without stockholder action.  Although Norwest has no current plans for the
  issuance of any shares of Preferred Stock, except as disclosed in this
  Prospectus, such shares, when and if issued, could have dividend, liquidation,
  voting and other rights superior to those of the Common Stock.

                                       38
<PAGE>
 
       Subject to any prior rights of any Preferred Stock then outstanding,
  holders of Common Stock are entitled to receive such dividends as are declared
  by Norwest's Board of Directors out of funds legally available for that
  purpose.  For information concerning legal limitations on the ability of
  Norwest's banking subsidiaries to supply funds to Norwest, see "CERTAIN
  REGULATORY CONSIDERATIONS."  Subject to the rights, if any, of any Preferred
  Stock then outstanding, all voting rights are vested in the holders of Common
  Stock, each share being entitled to one vote.  Subject to any prior rights of
  any Preferred Stock, in the event of liquidation, dissolution, or winding up
  of Norwest, holders of shares of Common Stock are entitled to receive pro rata
  any assets distributable to stockholders in respect of shares held by them.
  Holders of shares of Common Stock do not have any preemptive right to
  subscribe for any additional securities which may be issued by Norwest.  The
  outstanding shares of Common Stock are, and the Shares offered hereby will be,
  fully paid and nonassessable.  The transfer agent and registrar for the Common
  Stock is Norwest Bank Minnesota, N.A.  Each share of Common Stock also
  includes, and each share offered hereby will include, a right to purchase
  certain Preferred Stock.  See "Rights to Purchase Preferred Stock" below.

       The foregoing description of the material terms of the Common Stock does
  not purport to be complete and is qualified in its entirety by reference to
  Article Fourth of Norwest's Certificate of Incorporation.

      RIGHTS TO PURCHASE NORWEST PREFERRED STOCK.  On November 22, 1988, the
  Board of Directors of Norwest declared a dividend of one preferred share
  purchase right (collectively, the "Rights") for each outstanding share of
  Norwest Common Stock.  The dividend was paid on December 9, 1988, to
  stockholders of record on that date.  Holders of shares of Norwest Common
  Stock issued subsequent to that date, including those to be issued in
  connection with the Merger, will receive the Rights with their shares.  The
  Rights trade automatically with shares of Norwest Common Stock and become
  exercisable only under certain circumstances.  The Rights are designed to
  protect the interests of Norwest and its stockholders against coercive
  takeover tactics.  The purpose of the Rights is to encourage potential
  acquirors to negotiate with Norwest's Board of Directors prior to attempting a
  takeover and to give the Board leverage in negotiating on behalf of all
  stockholders the terms of any proposed takeover.  The Rights may, but are not
  intended to, deter takeover proposals.

      Upon becoming exercisable, each Right will entitle the registered holder
  to purchase from Norwest one four-hundredth of a share of Norwest Series A
  Junior Participating Preferred Stock (collectively, the "Junior Preferred
  Shares").  The stated purchase price for each one one-hundredth of a Junior
  Preferred Share is $175.00.  Until a Right is exercised, the holder of a
  Right, as such, will have no rights with respect to the Junior Preferred
  Shares including, without limitation, the right to vote or receive dividends.
  The purchase price is subject to adjustment upon the occurrence of certain
  events, including stock dividends on the Junior Preferred Shares or issuance
  of warrants for, or securities convertible on certain terms into, Junior
  Preferred Shares.  The number of Rights outstanding and the number of Junior
  Preferred Shares issuable upon exercise of the Rights are subject to
  adjustment in the event of a stock split of, or a stock dividend on, Norwest
  Common Stock.

      The Rights will become exercisable only if a person or group acquires or
  announces an offer to acquire 25% or more of the outstanding shares of Norwest
  Common Stock.  This triggering percentage may be reduced to no less than 15%
  by the Board of Directors prior to the time the Rights become exercisable.
  The Rights have certain additional features that will be triggered upon the
  occurrence of specified events:

                                      39
<PAGE>
 
      (1)  If a person or group acquires at least the triggering percentage of
      Norwest Common Stock, the Rights permit holders of the Rights, other than
      such person or group, to acquire Norwest Common Stock at 50% of market
      value.  However, this feature will not apply if a person or group which
      owns less than the triggering percentage acquires at least 85% of the
      outstanding shares of Norwest Common Stock pursuant to a cash tender offer
      for 100% of the outstanding Norwest Common Stock.

      (2)  After a person or group acquires at least the triggering percentage
      and before the acquiror owns 50% of the outstanding shares of Norwest
      Common Stock, the Board of Directors may exchange each Right, other than
      Rights owned by such acquiror, for one share of Norwest Common Stock or
      one four-hundredth of a Junior Preferred Share.

      (3)  In the event of certain business combinations involving Norwest or
      the sale of 50% or more of the assets or earning power of Norwest, the
      Rights permit holders of the Rights to purchase the stock of the acquiror
      at 50% of market value.

      The Junior Preferred Shares will not be redeemable.  Each Junior Preferred
  Share will be entitled to a minimum preferential quarterly dividend payment of
  $1.00 per share but will be entitled to an aggregate dividend of 400 times the
  dividend declared per share of Norwest Common Stock.  In the event of
  liquidation, the holders of the Junior Preferred Shares will be entitled to a
  minimum preferential liquidation payment of $400.00 per share but will be
  entitled to an aggregate payment of 400 times the payment made per share of
  Norwest Common Stock.  Each Junior Preferred Share will have 400 votes, voting
  together with the Norwest Common Stock.  Finally, in the event of any merger,
  consolidation, or other Reorganization in which Norwest Common Stock is
  exchanged, each Junior Preferred Share will be entitled to receive 400 times
  the amount received per share of Norwest Common Stock.  These rights are
  protected by customary antidilution provisions.

      At any time prior to the acquisition by a person or group of the
  triggering percentage or more of the outstanding shares of Norwest Common
  Stock, the Board of Directors may redeem the Rights in whole, but not in part,
  at a price of $.0025 per Right (the "Redemption Price").  The redemption of
  the Rights may be made effective at such time, on such basis, and with such
  conditions as the Board of Directors in its sole discretion may establish.
  Immediately upon any redemption of the Rights, the right to exercise the
  Rights will terminate and the only remaining right of the holders of Rights
  will be to receive the Redemption Price.

      The Rights will expire on November 23, 1998, unless extended or earlier
  redeemed by Norwest.  Generally, the terms of the Rights may be amended by the
  Board of Directors without the consent of the holders of the Rights.

      AMENDMENT OF CORPORATE CHARTER AND BYLAWS

      ARBI.  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.  ARBI's
  Bylaws provide that only the Board of Directors has the power to alter, amend,
  or repeal its Bylaws, or adopt new Bylaws.

      NORWEST.  The provisions of the DGCL governing the amendment of Norwest's
  Certificate of Incorporation are essentially the same as those of New Mexico
  law.  However, 

                                      40
<PAGE>
 
  Norwest's By-Laws provide that they may be altered or amended by the
  affirmative vote of a majority of the Board of Directors or the holders of a
  majority of the outstanding Norwest stock entitled to vote on the amendment.

      DISSENTERS' RIGHTS

      ARBI.  Under the NMBCA, shareholders of ARBI are entitled to exercise
  dissenters' rights and obtain payment of the fair value of their shares in
  cash if ARBI 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 a resolution of the Board of Directors
  provides for a right to dissent.  See the more detailed discussion below under
  "Rights of Dissenting ARBI Shareholders."

      NORWEST.  Under the DCGL, a stockholder is generally entitled to receive
  payment of the appraised value of such stockholder's shares if the stockholder
  dissents from a merger or consolidation.   However, appraisal rights are not
  available to holders of (a) shares listed on a national securities exchange or
  held of record by more than 2,000 persons or (b) shares of the corporation
  surviving a merger, if the Merger did not require the approval of the
  stockholders of such corporation, unless in either case, the holders of such
  stock are required by the terms of the Merger to accept anything other than
  (i) shares of stock of the surviving corporation, (ii) shares of stock of
  another corporation which are also listed on a national securities exchange or
  held by more than 2,000 holders, or (iii) cash in lieu of fractional shares of
  such stock.  Appraisal rights are not available to Norwest stockholders for a
  sale of assets or an amendment to the Certificate of Incorporation. Because
  shares of Norwest Common Stock are listed on both the NYSE and the CHX, and
  Norwest has more than 2,000 stockholders of record, its stockholders are not,
  subject to the aforementioned exceptions, entitled to any rights of appraisal
  in connection with mergers or consolidations involving Norwest.

      SPECIAL MEETINGS OF SHAREHOLDERS

      ARBI.  Under the NMBCA, a special meeting of shareholders may be called by
  ARBI's Board of Directors, 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.  ARBI's Bylaws permit
  special meetings of shareholders to be called by the President or the Board of
  Directors, and require the President to call a special meeting upon the
  request of the holders of not less than ten percent of the outstanding shares
  of ARBI Common Stock.

      NORWEST.  Under the DCGL and the By-Laws of Norwest, a special meeting of
  stockholders may be called only by the Chairman of the Board, a Vice Chairman,
  the President, or a majority of the Board of Directors.

                                      41

      DIRECTORS' DUTIES

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

      LIMITATION OF DIRECTORS' LIABILITY AND INDEMNIFICATION

      ARBI.  Under the NMBCA and ARBI's Articles of Incorporation, a director of
  ARBI 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 its Articles of Incorporation, ARBI 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 ARBI
  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 ARBI,
  that his or her conduct was in the best interests of ARBI; (ii) in all other
  cases, that his or her conduct was at least not opposed to ARBI'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 ARBI 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 Board
  of Directors of ARBI 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 ARBI (a "derivative action"), indemnification
  is only available for any reasonable expenses incurred.

                                      42
<PAGE>
 
       ARBI's Bylaws provide that expenses incurred in defending any action may
  be paid by ARBI 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 ARBI's Bylaws is substantially similar to the
  indemnification provisions in the NMBCA.

       NORWEST.  Under the DGCL, absent a provision in the certificate of
  incorporation to the contrary, directors can be held liable for gross
  negligence in connection with the decisions made on behalf of the corporation
  and the performance of their duty of care, but will not be liable for simple
  negligence.  As permitted under Delaware law, Norwest's Certificate of
  Incorporation 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 a 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
  derives improper personal benefit.  This provision protects Norwest's
  directors against personal liability for monetary damages from breaches of
  their duty of care.  However, it does not eliminate the director's duty of
  care.  For example, this provision in Norwest's Certificate of Incorporation
  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.

       Delaware law provides that directors, officers, and other employees and
  individuals may be indemnified against expenses (including attorneys' fees),
  judgments, fines, and amounts paid in settlement in connection with specified
  actions, suits, or proceedings, whether civil, criminal, administrative, or
  investigative (other than a derivative action) if they acted in good faith and
  in a manner they reasonably believed to be in, or not opposed to, the best
  interests of the corporation, and regarding any criminal action or proceeding,
  had no reasonable cause to believe their conduct was unlawful.  A similar
  standard is applicable in the case of derivative actions, except that
  indemnification only extends to expenses (including attorneys' fees) incurred
  in connection with the defense or settlement of such actions.  In the case of
  derivative actions, Delaware law requires court approval before there can be
  any indemnification where the person seeking indemnification has been found
  liable to the corporation.  To the extent that a person otherwise eligible to
  be indemnified is successful on the merits of any claim or defense described
  above, indemnification for expenses (including attorneys' fees) actually and
  reasonably incurred is mandated by Delaware law.

       Norwest's Certificate of Incorporation provides that Norwest must
  indemnify, to the fullest extent authorized by Delaware law, 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 of Directors.  Norwest's Certificate of
  Incorporation 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 Delaware law, 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.

                                      43
<PAGE>
 
       Norwest's Certificate of Incorporation authorizes Norwest to provide
  similar indemnification to employees or agents of Norwest.

       Pursuant to Norwest's Certificate of Incorporation, 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
  Delaware law.

       The right to indemnification is not exclusive of any other right which
  any person may have or acquire under any statute, provision of Norwest's
  Certificate of Incorporation or By-Laws, agreement, vote of stockholders or
  disinterested directors, or otherwise.

      ANTITAKEOVER STATUTES

      ARBI.  The NMBCA does not include any provision that regulates the
  accumulation of shares of voting stock of, or business combinations with, New
  Mexico corporations.

      NORWEST.  The Delaware antitakeover statute governs business combinations
  between a publicly held Delaware corporation having certain numbers of
  stockholders or listed on certain exchanges and an interested stockholder.
  This statute is designed primarily to regulate the second step of a two-tiered
  takeover attempt.  Delaware law broadly defines a "business combination" as
  including a merger, sale of assets, issuance of voting stock, and various
  other types of transactions with an interested stockholder and other related
  parties.  An "interested stockholder" is defined as any person who
  beneficially owns, directly or indirectly, 15% or more of the outstanding
  voting stock of a corporation.  Delaware law prohibits a corporation from
  engaging in a business combination with an interested stockholder for a period
  of three years following the date on which the stockholder became an
  interested stockholder, unless (a) the board of directors approved the
  business combination before the stockholder became an interested stockholder,
  (b) upon consummation of the transaction which resulted in the stockholder
  becoming an interested stockholder, such stockholder owned at least 85% of the
  voting stock outstanding when the transaction began, excluding in computing
  such percentage shares held by certain types of stockholders, or (c) the board
  of directors approved the business combination after the stockholder became an
  interested stockholder and the business combination was approved by at least
  two-thirds of the outstanding voting stock not owned by such stockholder.

      In addition to being subject to the laws of Delaware, Norwest and ARBI, as
  bank holding companies, are subject to various provisions of federal law with
  respect to mergers, consolidations, and certain other corporate transactions.

      RESTRICTIONS ON DECLARATION OF DIVIDENDS

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

      NORWEST.  Under the DGCL, Norwest's Board of Directors may authorize and
  pay dividends to its shareholders either (i) out of surplus, which is that
  part of a corporation's net assets which is in excess of the amount determined
  by the board of directors to be capital, 

                                      44
<PAGE>
 
  provided that, for corporation like Norwest with par value capital stock, a
  corporation's capital may not be less than the aggregate par value of its
  issued shares, or (ii) if there is no surplus, out of the corporation's net
  profits for the fiscal year in which the dividend is declared and/or the
  preceding fiscal year. The board of directors of a Delaware corporation may
  reduce the corporation's capital, provided that the corporation's assets
  remaining after the reduction are sufficient to pay any of the corporation's
  debts for which payment has not otherwise been provided.

  RIGHTS OF DISSENTING ARBI SHAREHOLDERS

      Shareholders of ARBI 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 ARBI 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 Merger Agreement and, accordingly,
  will not be entitled to exercise dissenters' rights in connection with the
  Merger.  If the Merger is approved, the shareholder may, within ten days after
  the date on which the vote on the Merger is taken, make written demand on
  ARBI, 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 ARBI 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 ARBI shareholders, will
  cause the shareholder to lose his dissenters' rights with respect to such
  shares.

      Within ten days after the Effective Date of the Merger, ARBI 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 ARBI to be
  the fair value of the shares.  The notice and offer must be accompanied by
  ARBI's balance sheet as of the latest 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 Date of the Merger, the shareholder and ARBI reach an
  agreement as to the fair value of the shareholder's shares, ARBI will remit
  the fair value payment agreed upon to the shareholder within 90 days after the
  Effective Date of the Merger and upon surrender of the certificates
  representing such shares.  If ARBI 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, ARBI shall, or at
  ARBI's election at any time within such 60-day period ARBI may, file a
  petition in the Thirteenth Judicial District Court, County of Valencia, State
  of New Mexico (the "Court"), asking that the Court determine the fair value of
  the shares.  If ARBI fails to file such a petition, any shareholder demanding
  appraisal rights may do so on ARBI's behalf.  All shareholders asserting
  appraisal rights will be made parties to any court action filed to determine
  such fair value.  No demand for appraisal may be withdrawn without the consent
  of ARBI.  If a demand is withdrawn with the consent of ARBI, 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.  

                                      45
<PAGE>
 
  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 ARBI to all dissenting holders of ARBI 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 ARBI, 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 ARBI'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 ARBI if the determined fair value of the shares materially
  exceeds the amount offered by ARBI or if ARBI fails to make a required offer.

      Upon receiving a demand for payment from a dissenting shareholder, ARBI 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 ARBI,
  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 Date of the Merger, no shareholder who has
  demanded appraisal rights will be entitled to vote such shareholder's shares
  of ARBI 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 ARBI
  should be sent to ARBI 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 EXHIBIT 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.

  CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

      This description of certain federal income tax considerations with respect
  to the Merger is included solely for the information of ARBI 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 ARBI shareholder will
  depend upon the individual situation of such shareholder.  Furthermore,
  special tax considerations may apply to ARBI shareholders who are insurance
  companies, securities dealers, financial institutions, and foreign persons.
  Therefore, EACH ARBI SHAREHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX
  ADVISOR CONCERNING THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO SUCH
  SHAREHOLDER.

                                       46

<PAGE>
 
      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 ARBI
  as a result of the Merger; (ii) no gain or loss will be recognized by holders
  of ARBI Common Stock upon the receipt of Norwest Common Stock in exchange for
  ARBI 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 and the receipt of the interest in the Trust; and (iii) the aggregate
  adjusted tax basis of the shares of Norwest Common Stock received by the
  holders of ARBI Common Stock surrendered in exchange therefor will be equal to
  the tax basis of such shareholder's shares of ARBI Common Stock (reduced by
  the amount allocable to fractional share interests for which cash is
  received).

      ARBI 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 ARBI of the opinion of Bracewell & Patterson,
  L.L.P., Houston, Texas, dated as of the Closing Date, substantially to the
  effect that, on the basis of facts, representations and assumptions set forth
  or referred to in such opinions, the principal federal income tax consequences
  of the Merger under current law will be as set forth 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 ARBI.  The tax opinion will not address the consequences of
  the Merger on ARBI 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 ARBI will
  be based on the assumption that the shareholders of ARBI 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 ARBI Common Stock outstanding immediately prior to the Merger.  For
  purposes of such determination, shares of ARBI Common Stock that are exchanged
  for cash or other property, or surrendered by ARBI 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 ARBI Common Stock immediately prior to the Merger.

      Holders of ARBI 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 ARBI 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 ARBI 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 ARBI Common Stock or (ii)
  dividend distributions received on account of such stock.

                                       47

<PAGE>
 
      Those ARBI shareholders who elect to participate in the Merger will treat
  ARBI's distribution of Trust interests as a noncash, dividend-type
  distribution on account of their ARBI stock.  The amount of the distribution
  will be the fair market value of such interest (the pro rata share of the fair
  market value of the Trust assets represented by such interest).  To the extent
  ARBI has current or accumulated earnings and profits equal to or in excess of
  the value of the Trust interests distributed, each such ARBI shareholder will
  treat the distribution as a dividend taxable at ordinary income rates in the
  year received.  To the extent the value of the distributed Trust interests
  exceed ARBI's current and accumulated earnings and profits, such excess will
  be treated (i) first, as a recovery of such shareholder's basis in his or her
  ARBI stock, and (ii) second, as a sale of such stock.  Each such shareholder
  will take a tax basis in his or her Trust interest equal to the fair market
  value of such interest as of the date of distribution.  Although ARBI will
  obtain, prior to the Effective Date of the Merger, an appraisal of the artwork
  which constitutes the corpus of the Trust in order to determine the fair
  market value of the Trust interests, there can be no assurance that the IRS
  will concur in such valuation.

      Holders of ARBI Common Stock who do not participate in the Merger must
  consult with their individual tax advisors to determine the correct income tax
  treatment of the Trust interests received from ARBI.  The proper tax treatment
  will depend upon the individual situation of each holder.

      The Trust is a liquidating trust for federal income tax purposes.
  Therefore, the items of income, gain, loss, and deduction realized by the
  Trust will pass through to the holders of Trust interests.  The Trust itself
  will not pay taxes, but will be a pure "flow through" entity for tax purposes.
  The purpose of the Trust is to hold the assets until they can be sold.  If the
  Trust assets are disposed of at prices which exceed their fair market value as
  of the date the Trust interests were distributed to ARBI shareholders, each
  holder of a Trust interest will recognize gains in the amount of such excess.
  If the proceeds from the sale of the Trust Assets are less than the fair
  market value of such assets as of the date the Trust interests were
  distributed to the ARBI shareholders, each holder of a Trust interest will
  recognize a loss equal to the amount of such difference.  Assuming that each
  holder of a Trust interest holds such interest for investment purposes, this
  gain or loss will be characterized as capital gain or loss.  Although the
  purpose of the Trust is to sell the Trust Assets and distribute the net
  proceeds thereof to the holders of interests therein, the terms of the Trust
  give the Trustee substantial discretion with respect to the timing of such
  distributions.  Accordingly, no assurance may be given that the Trustee will
  distribute the proceeds of any sale giving rise to a taxable gain in time for
  the holders of interests in the Trust to pay the federal income tax due in
  respect of such disposition.  In such event, holders of interests in the Trust
  may incur tax liability as a result of the actions of the Trustee and not
  receive the funds necessary to pay such tax liability.  See "Liquidating
  Trust" for a discussion of the terms of the Trust.

      Shareholders of ARBI stock who receive Norwest Common Stock pursuant to
  the Merger will receive certain rights to acquire additional Norwest stock
  under certain circumstances.  See "Certain Differences in Rights of
  Shareholders--Capital Stock."  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.

      ARBI 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.  

                                       48

<PAGE>
 
  Thus, loan transactions between parties, compensation arrangements, noncompete
  agreements, consulting arrangements, 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 ARBI 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 ARBI
  shareholders, ARBI 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, ARBI 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, ARBI
  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 ARBI upon
  consummation of the Merger 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 ARBI or Norwest as that term is defined in
  the rules under the Securities Act.  Norwest Common Stock received by those
  shareholders of ARBI who are deemed to be "affiliates" of ARBI 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 ARBI
  generally include individuals or entities that control, are controlled by or
  are under common control with, ARBI, and may include the executive officers
  and directors of ARBI as well as certain principal shareholders of ARBI.  In
  the Merger Agreement, ARBI has agreed to use its best efforts to cause each
  ARBI shareholder who is an executive officer or director of ARBI or who may
  otherwise reasonably be deemed to be an affiliate of ARBI to enter into an
  agreement with Norwest providing that such affiliate will not sell, transfer,
  or otherwise dispose of the shares of Norwest Common Stock to be received by
  such person in the Merger except in compliance with the applicable provisions
  of the Securities Act and the rules and regulations promulgated thereunder.
  This Proxy Statement-Prospectus does not cover any resales of Norwest Common
  Stock received by affiliates of ARBI.

      The Merger Agreement provides for the filing by Norwest of listing
  applications with the NYSE and the CHX covering the shares of Norwest Common
  Stock issuable upon consummation of the Merger.  It is a condition to the
  consummation of the Merger that such shares of Norwest Common Stock shall have
  been authorized for listing on the NYSE and the CHX.

  DIVIDEND REINVESTMENT AND OPTIONAL CASH PAYMENT PLAN

      Norwest currently has an automatic Dividend Reinvestment and Optional Cash
  Payment Plan which provides in substance, for those stockholders who elect to
  participate, that dividends on Norwest Common Stock will be reinvested in
  shares of Norwest Common Stock at market price (as defined in the plan).  The
  plan also permits participants to invest through voluntary cash payments,
  within certain dollar limitations, in additional shares of Norwest Common
  Stock at the market price (as defined in the plan) of such stock at the time
  of purchase.  It is anticipated that after the Effective Time of the Merger,
  Norwest will continue to offer its Dividend Reinvestment and Optional Cash
  Payment Plan and that shareholders of ARBI who receive Norwest Common Stock in
  the Merger will have the right to participate therein.

  ACCOUNTING TREATMENT

      It is anticipated that the Merger will be accounted for as a "purchase"
  transaction in accordance with generally accepted accounting principles.

  EXPENSES

      Norwest and ARBI will each pay their own expenses in connection with the
  Merger, including fees and expenses of their respective accountants and
  counsel.

     The Bank's main banking facility in Belen consists of a single structure   
located on an approximately four acre tract of land at the corner of Main       
Street and Becker in Belen, New Mexico.  The main facility is a four story,     
44,200 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 ARBI.

     The Bank experiences considerable competition in both attracting deposits  
and lending funds.  Competition in lending comes principally from other         
commercial banks and savings and loan associations located in the Bank's        
market area and, to a lesser extent, from mortgage companies, insurance         
companies, governmental agencies, credit unions, area estate investment         
trusts, and other financial institutions.  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, convenience of office         
locations, and extent of services offered.  In the conduct of certain aspects   
of its banking business, the Bank competes not only with the above mentioned    
institutions, but additionally with insurance companies, small loan companies   
and other financial institutions.                                               
                                                                                
LEGAL PROCEEDINGS                                                               
                                                                                
     The nature of the Bank's business causes it to be involved in routine      
legal proceedings from time to time. Other than such proceedings incidental to  
the Bank's business, 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.

             MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL   
                     CONDITION AND RESULTS OF OPERATIONS 



GENERAL

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

ARBI, a one-bank holding company headquartered in Belen, 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 which provides a full range of commercial banking services.  See
"Information About ARBI--General."  References to the operations of ARBI include
the operations of the Bank, unless the context otherwise requires.

ARBI'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 gains and
losses on its investment portfolio, by its required provisions for loan losses
and by the level of its operating expenses.  All aspects of the Bank's
operations are affected by general market, economic and competitive conditions.

FINANCIAL CONDITION

Total assets increased by $3,689,000, or 1.7%, during the first six months of
1994 to $222,522,000 at June 30, 1994 following an increase of $6,753,000, or
3.2%, during 1993 to $218,833,000 at December 31, 1993.  These increases were
primarily in investment securities, but were largely offset by a 15.4% decrease
in loans during 1993.

Loans increased approximately 0.9% in the first six months of 1994 by $725,000
to $81,555,000 at June 30, 1994 and decreased $14,679,000 during 1993 to
$80,830,000 at December 31, 1993.  The modest net increase in loans during the
six months ended June 30, 1994 was primarily the result of increases in
commercial business and consumer loans of $3,471,000 and $713,000, respectively,
and decreases in residential and agricultural real estate loans of $2,180,000
and $989,000, respectively.  During 1993, decreases occurred in all major
categories of loans except commercial real estate and real estate construction
loans, which increased moderately.  The decreases in 1993 were attributable to
weak loan demand, residential real estate loan refinancing activity and
managements' continued focus on strengthening lending controls and underwriting
standards.  See "--REGULATORY MATTERS."

Investment securities increased in the first six months of 1994 by $9,381,000,
or 8.3%, to $122,161,000 at June 30, 1994 and increased $19,736,000, or 21.2%,
during 1993 to $112,780,000 at December 31, 1993.  The increases occurred
primarily in securities of the U.S. Treasury, U.S. Government Agencies and state
and political subdivisions.  The increase during the first six months of 1994
was primarily funded by an increase in average deposits and a decrease in
federal funds sold and is largely attributable to weak loan demand.  The 1993
increase was funded by a decrease in average loans which was mainly due to weak
loan demand and the other factors discussed in the preceding paragraph.

RESULTS OF OPERATIONS

Net interest income is the primary source of income for ARBI and represents 

                                       54

<PAGE>
 
the amount by which interest and fees generated by earning assets exceed the
cost of funds, primarily interest paid to the Bank's 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 THREE MONTHS ENDED JUNE 30, 1994 AND 1993

        EARNINGS PERFORMANCE

ARBI earned net income of $567,000 and $393,000 for the three months ended June
30, 1994 and 1993, respectively.  The 44.3% increase in 1994 second quarter net
income of $174,000 was primarily attributable to a 14.3% increase in net
interest income of $307,000 and a decrease in the provision for loan losses from
$150,000 to zero, partially offset by a 9.0% decrease in non-interest income of
$47,000 and a 9.6% increase in non-interest expense of $192,000.

The consolidated annualized return on average assets was 1.00% for the second
quarter of 1994, compared to .75% for the second quarter of 1993.  Annualized
return on average stockholders' equity was 10.87% for the second quarter of
1994, compared to 9.21% for the second quarter of 1993.  The improvement in
these ratios was primarily attributable to the increase in net income discussed
in the preceding paragraph.  On a per-share basis, net income for the second
quarter of 1994 and 1993 were $1.38 and $0.95, respectively.

The following is a condensed summary of the consolidated statements of
operations (dollars in thousands):

        NET INTEREST INCOME

ARBI'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."

for the three months ended June 30:
<TABLE>

- ---------------------------------------------------------
  Net yield on interest-earning assets        4.82%  4.53%
=========================================================
 
</TABLE>

Net interest income was $2,448,000 for the second quarter of 1994, compared with
$2,141,000 for the second quarter of 1993.  The 14.3% increase was due primarily
to higher securities balances, and lower rates paid on interest-bearing
liabilities partially offset by lower loan balances net of the benefit of an
increased average loan interest yield.

Total interest income increased to $3,883,000 or 6.3% for the second quarter of
1994 as compared to $3,653,000 for the second quarter of 1993.  Average
interest-earning assets increased to $205,990,000 in 1994 from $189,559,000 in
1993.  Earning asset yields decreased 9 basis points for the second quarter of
1994 as compared to 1993.  The decrease in earning asset yields was due to a
decrease in average yield earned on securities offset by increases in average
yields on loans and federal funds sold.

Total interest expense for the second quarter of 1994 of $1,435,000 declined
from $1,512,000 for the second quarter of 1993.  This 5.1% decline was
attributable primarily to rates on interest-bearing liabilities decreasing 33
basis points to 3.26% in 1994, from 3.59% in 1993.

The movements in earning asset yields and average rates paid on interest-bearing
liabilities discussed above were caused primarily by general economic and market
conditions which moved interest rates lower in 1993 with an uptrend during the
first six months of 1994.  Although interest rates were trending upward in the
second quarter of 1994, average yield earned on securities and rates paid on
interest-bearing liabilities did not fully respond to such increases during such
period due to contractual maturities of securities and time deposits and
relatively weak market demand for bank deposits.  The increase in average yield
earned on loans was also, in part, due to a decrease in nonaccrual loans.

   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 for loan losses and
recoveries on charged-off loans are credited to the allowance.  ARBI's provision
for loan losses was $-0- and $150,000 for the second quarter of 1994 and 1993,
respectively.

There were net recoveries (recoveries net of charge-offs) of $351,000 for the
second quarter of 1994 and $4,000 for the second quarter of 1993.  The allowance
for loan losses as a percentage of loans was 3.02% and 3.56% at June 30, 1994
and 1993, respectively.

   NON-INTEREST INCOME

The Bank's principal source of non-interest income is service charges on deposit
accounts.  Other sources are net gains or losses from sales of securities, loans
and other assets and a variety of other service charges and fees, including safe
deposit box rent, printed check sales and credit life insurance sales.

Non-interest income decreased to $475,000 for the second quarter of 1994
compared to $522,000 for the second quarter of 1993.  The $47,000 (9.0%)
decrease is primarily due to decreases of approximately $16,000 and $41,000 in

                                       58
<PAGE>
 
deposit account service charges and net gains from loan sales, respectively,
partially offset by net increases in a variety of other non-interest income
items, none of which individually exceeded $15,000.

=======================================================================
</TABLE>

Total non-interest expenses increased to $2,182,000 for the second quarter of
1994, compared to $1,990,000 for the second quarter of 1993.  The 9.6% increase
is primarily due to legal, professional and officer/employee expenses of
approximately $350,000 relating to the prospective sale of ARBI partially offset
by decreases in a variety of expense items.


  COMPARISON OF SIX MONTHS ENDED JUNE 30, 1994 AND 1993

   EARNINGS PERFORMANCE

ARBI earned net income of $1,083,000 and $785,000 for the six months ended June
30, 1994 and 1993, respectively.  The 38.0% increase in net income of $298,000
is largely attributable to an increase in net interest income of $350,000 and a
decrease in the provision for loan losses from $275,000 to zero, partially
offset by a decrease in non-interest income of $68,000 and an increase in non-
interest expense of $187,000.

The consolidated annualized return on average assets was .98% for the first six
months of 1994, compared to .75% for the first six months of 1993.  Annualized
return on average stockholders' equity was 10.52% for the first six months of
1994, compared to 9.36% for the first six months of 1993.  The improvement in
these ratios was primarily attributable to the increase in net

                                       59

income discussed in the preceding paragraph.  On a per-share basis, net income

   NET INTEREST INCOME

ARBI'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 change in interest income/expense attributable to volume reflects the change
in volume times the prior period's rate and the change in interest
income/expense attributable to rate reflects the change in rates times the prior
period's volume.  The change due to combined rate/volume variance is allocated
to the change due to rate and the change due to volume on the basis of the
percentage that results by dividing the change in each volume and rate by the
sum of the changes in volume and rate (excluding the combined rate/volume

for the six months ended June 30:

- ---------------------------------------------------------
  Net yield on interest-earning assets        4.70%  4.60%

</TABLE>

Net interest income was $4,697,000 for the first six months of 1994, compared
with $4,347,000 for the first six months of 1993.  The 8.1% increase was due
primarily to higher securities balances net of the effect of a lower average
securities interest yield and lower rates paid on interest-bearing liabilities
partially offset by lower loan balances net of the benefit of increased average
loan interest yield.

Total interest income increased to $7,527,000 or 1.5% for the first six months
of 1994 as compared to $7,414,000 for the first six months of 1993.  Average
interest-earning assets increased 7.0% to $203,977,000 in 1994 from $190,625,000
in 1993.  Earning asset yields decreased 30 basis points for the first six
months of 1994 as compared to 1993.  The decrease in earning asset yields was
due to a decrease in average yield earned on securities offset by increases in
average yields on loans and federal funds sold.

Total interest expense for the first six months of 1994 of $2,830,000 declined
from $3,067,000 or 7.7% for the first six months of 1993.  This decline was
attributable primarily to average rates paid on interest-bearing liabilities
decreasing 39 basis points to 3.26% in 1994, from 3.65% in 1993.

The movements in earning asset yields and average rates paid on interest-bearing
liabilities discussed above were caused primarily by general economic and market
conditions which caused interest rates to decline in 1993, followed by an
uptrend during the first six months of 1994. Although interest rates have
increased during the first six months of 1994, average yield earned on
securities and rates paid on interest-bearing liabilities did not fully respond
to such increases during such period, due to contractual maturities of
securities and time deposits and relatively weak market demand for bank
deposits. The increase in average yield earned on loans was also, in part, due
to a decrease in nonaccrual loans.

   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 for loan losses and

                                       62
<PAGE>
 
recoveries on charged-off loans are credited to the allowance.  ARBI's provision
for loan losses was $-0- and $275,000 for the first six months of 1994 and 1993,
respectively.

There were net recoveries (recoveries net of charge-offs) of $312,000 for the
first six months of 1994 and net charge-offs of $191,000 for the first six
months of 1993.  The allowance for loan losses as a percentage of loans was
3.02% and 3.56% at June 30, 1994 and 1993, respectively.

   NON-INTEREST INCOME

The Bank's principal source of non-interest income is service charges on deposit
accounts.  Other sources are net gains or losses from sales of securities, loans
and other assets and a variety of other service charges and fees, including safe
deposit box rent, printed check sales and credit life insurance sales.

Non-interest income decreased to $890,000 for the first six months of 1994
compared to $958,000 for the first six months of 1993.  The $68,000 (7.1%)
decrease is primarily due to decreases of approximately $26,000, $42,000 and
$55,000 in deposit account service charges, net gains/losses on sales of
securities and net gains from loan sales, respectively, partially offset by net
increases in a variety of other non-interest income items, none of which
individually exceeded $30,000.

</TABLE>

Total non-interest expense increased to $4,165,000 for the first six months of
1994, compared to $3,978,000 for the first six months of 1993.  The 4.7%
increase is primarily due to legal, professional and officer/employee expenses
in the second quarter of 1994 of approximately $350,000 relating to the
prospective sale of ARBI, partially offset by decreases in a variety of expense
items.


  COMPARISONS OF YEARS ENDED DECEMBER 31, 1993, 1992 AND 1991

   EARNINGS PERFORMANCE

ARBI earned net income of $2,596,000 in 1993 and $1,396,000 in 1992.  In 1991,
there was a net loss of $752,000.  The 86.0% increase in net income of
$1,200,000 in 1993 compared to 1992 is attributable to a 2.3% increase in net
interest income of $195,000 and a 145.3% decrease in the provision for loan
losses of $2,165,000, partially offset by an 11.3% decrease in non-interest
income of $262,000 and increases in non-interest expense and income taxes of
$210,000  (or 2.8%) and $688,000 (or 177.8%), respectively.  The increase in net
income to $1,396,000 in 1992 compared to a loss of $752,000 in 1991 is partially
attributable to a 4.4% increase in net interest income of $363,000 and a 29.0%
increase in non-interest income of $521,000.  Also contributing to the improved
results in 1992 was a 65.2%  decrease in the provision for loan losses of
$2,788,000, partially offset by increases in non-interest expense and income
taxes of $605,000 (or 8.6%) and $919,000 (or 172.7%), respectively.

The decreases in the provision for loan losses from $4,278,000 in 1991 to
$1,490,000 in 1992 and to a negative provision of ($675,000) in 1993 were the
primary reason for the improvements in net income in 1992 and 1993 discussed
above.  Such decreases in the provision for loan losses were possible as a
result of managements' efforts to enhance loan underwriting and servicing,
improve the quality and objectivity of the loan review function and strengthen
the special assets function, which among other things, is responsible for
workout and resolution of problem assets.  See "--REGULATORY MATTERS."  Such
management efforts have produced steady and significant reductions in net loan
charge-offs in 1992 and 1993 (See "--COMPARISON OF THE YEARS ENDED DECEMBER 31,
1993, 1992, AND 1991--Provision for Loan Losses"), as well as improvements in 
non-current and classified/criticized assets.  These factors, among others,
including improved national and local economic conditions between 1991 and 1993,
were material in managements' evaluation of the quality of the loan portfolio
and managements' determination that loan quality had improved sufficiently to
warrant the decrease in the provision for loan losses in 1992.  Also, based on
these factors, a reduction in the allowance of $1,000,000 was recorded as of
December 31, 1993 to bring the total allowance to a level considered appropriate
by management, resulting in a negative provision of ($675,000).

The consolidated return (loss) on average assets was 1.21% in 1993 compared to
.65% in 1992 and (.36)% in 1991.  Return (loss) on average stockholders' equity
was 14.96% in 1993 compared to 8.81% and (4.58)% in 1992 and 1991, respectively.
The improvements in these ratios were primarily attributable to the increases in
net income/loss discussed in the second preceding paragraph.  On a per share
basis, net income (loss) for the years 1993, 1992 and 1991 were $6.28, $3.39 and
$(1.82), respectively.

   NET INTEREST INCOME

ARBI'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 change in interest income/expense attributable to volume reflects the change
in volume times the prior year's rate and the change in interest income/expense
attributable to rate reflects the change in rates times the prior year's volume.
The change due to combined rate/volume variance is allocated to the change due
to rate and the change due to volume on the basis of the percentage that results
by dividing the change in each volume and rate by the sum of the changes in
volume and rate (excluding the combined

Short-term borrowings primarily consist of repurchase agreements with various
bank customers.  These repurchase agreements are short term with specific
maturity dates and are generally issued for periods less than one year.  They
have fixed interest rates.  Terms of the agreements require the sale and
subsequent repurchase of specified U.S. Treasury or Government Agency securities
at a fixed price.  Banks are not required to maintain reserves on repurchase
agreements or incur FDIC charges with respect thereto.  Also included in short
term borrowings were funds borrowed from time to time under a line of credit
with a commercial bank to facilitate repurchase of shares of ARBI Common Stock.

The following table shows the net yield on interest-earning assets:

Net interest income increased from $8,589,000 in 1992 to $8,784,000 in 1993, an
improvement of 2.3%.  During 1992 net interest income increased 4.4% compared
with the $8,226,000 earned in 1991.  During the three years ended December 31,
1993 interest rates in the United States were in a general decline with short-
term interest rates falling faster than long-term rates.

Total interest income decreased to $14,781,000 or 10.5% in 1993 as compared to
$16,507,000 in 1992, which was down 11.4% from $18,634,000 in 1991.  Earning
asset yields declined to 7.74% in 1993 as compared to 8.55% and 9.85% in 1992
and 1991, respectively, as a result of declining interest rates.  The lower net
interest income was also attributable to a 16.8% decrease in average loans to
$88,767,000 in 1993, compared to $106,737,000 and $120,356,000 in 1992 and 1991,
respectively.  These decreases were partially offset by an increase of 17.7% in
average investment securities to $98,112,000 in 1993, compared to $83,377,000 in
1992, which in turn represented a 30.6% increase over the $63,830,000 average
balance in 1991.  See "CERTAIN SELECTED STATISTICAL INFORMATION" for information
regarding ARBI's average balances during the three years ended December 31,
1993.

Total interest expense in 1993 of $5,997,000 declined 24.3% from $7,918,000 in
1992, which was down 23.9% from $10,408,000 in 1991.  This decline was
attributable primarily to rates on interest-bearing liabilities declining to
3.51% in 1993, from 4.49% in 1992 and 6.10% in 1991.  The 98 basis point decline
from 1992 to 1993 and the 161 basis point decline from 1991 to 1992 were caused
by general economic and market conditions.

   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.  ARBI's provision (negative
provision) for loan losses was $(675,000), $1,490,000 and $4,278,000 in 1993,
1992 and 1991, respectively.  See "--COMPARISON OF THE YEARS ENDED DECEMBER
31, 1993, 1992 AND 1991--Earnings Performance."  Net loans charged off were
$298,415, $1,993,861 and $2,226,460 in 1993, 1992 and 1991, respectively.

The allowance for loan losses as a percentage of loans was 2.66%, 3.27% and
3.11% at December 31, 1993, 1992 and 1991, respectively.

</TABLE> 
 
The Bank's principal source of non-interest income is service charges on deposit
accounts.  Other sources are net gains or losses from sales of securities, loans
and other assets and a variety of other service charges and fees, including safe
deposit box rent, printed check sales and credit life insurance sales.

Non-interest income decreased 11.3% to $2,054,000 in 1993 compared to $2,316,000
in 1992, which was up 29.0% from $1,795,000 in 1991.  The decrease in 1993 was
primarily due to an 83.9% decrease in the net gain on sale of investments to
$92,000 from $573,000 and a 3.4% decrease in deposit account service charges
partially offset by a 344.9% increase in other income from $78,000 in 1992 to
$347,000 in 1993.  The 1993 increase in other income was attributable to a one
time New Mexico gross receipts tax refund of $110,000, $117,000 in net gains
from loan sales which were zero in 1992 and net increases in a variety of other
non-interest income items none of which individually exceeded $50,000.  The
increase in 1992 from 1991 was primarily attributable to a 274.5% increase in
the net gain on sale of securities and a 9.8% increase in deposit account
service charges partially offset by a 25.7% net decrease in a variety of other
non-interest income items.

</TABLE>

Total non-interest expense increased 2.8% to $7,842,000 in 1993, compared to
$7,632,000 in 1992, which in turn represented an 8.6% increase over the
$7,027,000 for 1991.  These increases were largely attributable to additional
staff, consultants and attorneys in 1993 and 1992 to help develop and implement
a corrective action plan pursuant to the memorandum discussed under 
"--REGULATORY MATTERS" below.

FDIC insurance assessments increased to $530,000 or 24.1% in 1993 from $427,000
in 1992, which was up 15.4% from $370,000 in 1991.  The increases were primarily
due to increased premium rates in these periods, attributable, in part, to the
matters discussed under "--REGULATORY MATTERS" below.

REGULATORY MATTERS

In June 1992, the Board of Directors of the Bank entered into a Memorandum of
Understanding (Memorandum) with the Office of the Comptroller of the Currency
(OCC) that required the Bank to take a number of actions to strengthen the
Bank's financial condition, including a review of the allowance for loan losses
and submission of a three-year capital plan.  In addition, the Memorandum
required the formulation and enhancement of certain departments along with the
establishment and implementation of a number of administrative policies and
procedures relating to, among other things, loan review, appraisals and the
process of determining the adequacy of the allowance for possible loan losses.
The Memorandum also required the Bank to maintain certain minimum capital levels
and obtain the approval of the OCC prior to the declaration or payment of any
dividends.

The OCC conducted an examination of the Bank as of December 31, 1993, which
disclosed that the overall condition of the Bank was satisfactory and that the
Bank was in substantial compliance with the Memorandum.  As a result, the
Memorandum was terminated on March 15, 1994.

INCOME TAXES

ARBI is subject to Federal and New Mexico income taxes which fluctuate from
period to period with fluctuations in ARBI's earnings performance.

STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS

In February 1992, 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 1993, ARBI
adopted SFAS 109.  The change in method of accounting for income taxes had no
significant effect.

The Financial Accounting Standards Board has issued Statement 114 (SFAS 114),
"Accounting by Creditors for Impairment of a Loan."  The Statement applies 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 requires loans, to which it applies, 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 Statement is effective for
fiscal years beginning after December 15, 1994.  The effects of this Statement
have not yet been evaluated.

Effective January 1, 1994, ARBI adopted Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities," (FAS 115).  Accordingly, beginning on January 1, 1994, pursuant to
ARBI'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 as a separate component of stockholders' equity.  On January 1,
1994, ARBI recorded an increase of $1,970,000, net of tax, in stockholders'
equity.  At June 30, 1994 the stockholders' equity component for net unrealized
gains on securities available for sale was $1,292,000.  The remaining securities
are deemed to be held to maturity and are reported at amortized cost.  On
January 1 and June 30, 1994 net unrealized gains/(losses) on securities held to
maturity were approximately $3,633,000 and ($1,947,000), respectively.  The
$678,000 net decrease in stockholders' equity discussed above and the $5,580,000
net unrealized depreciation of held to maturity securities during the six months
ended June 30, 1994 was largely attributable to rising market interest rates.

FUNDING SOURCES AND LIQUIDITY MANAGEMENT

ARBI relies primarily on the Bank for its source of cash.  The cash flow from
the Bank to ARBI comes in the form of dividends and tax benefits.  The Bank is
presently restricted in paying dividends only by the general regulatory
capital requirements that apply to all banks.  See "Capital Management of the
Bank."  At June 30, 1994, the Bank estimates that it has excess accumulated
earnings of over $5,000,000 available for distribution.

The assets of the Bank are primarily funded through the use of borrowings in the
form of deposits and short-term borrowings.  The maintenance of an adequate
level of liquidity is necessary to ensure that sufficient funds are available to
meet customers' loan demand and deposit withdrawals.  The 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, 1992, 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 June 30, 1994 and December 31, 1993 (dollars in thousands) are summarized as
follows:

As a supplement to the risk-based capital guidelines, the Federal Reserve Board
has also adopted a minimum ratio of tier 1 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 3.0%.  First National Bank of Belen's
actual tier 1 leverage ratio was 8.8% at both  June 30, 1994 and December 31,
1993.

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.

INTERESTS OF MANAGEMENT AND OTHERS IN CERTAIN TRANSACTIONS                      
                                                                                
     In considering the recommendation of the ARBI Board of Directors with      
respect to the Merger Agreement, shareholders should be aware that certain      
executive officers and directors of ARBI have certain interests in the Merger   
that are in addition to the interests of the shareholders of ARBI generally.    
The ARBI Board of Directors was aware of these interests and considered them,   
among other matters, in approving the Merger Agreement.                         
                                                                                
     Pursuant to the Merger Agreement, Norwest has agreed, among other things,  
to (i) use its best efforts to maintain, for three years following the          
Effective Time of the Merger, directors' and officers' liability insurance for  
future claims arising out of occurrences prior to the Effective Time of the     
Merger having terms and conditions substantially similar to those policies      
customarily maintained by similar financial institutions, and (ii) insure that  
all rights to indemnification in ARBI's Articles of Incorporation, and in the   
Articles of Association and Bylaws of the Bank, as in effect on June 6, 1994,   
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 for three years after the          
Effective Time of the Merger.

       Certain of the principal shareholders of ARBI and the directors and
  executive officers of ARBI 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 ARBI, 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
  ARBI's principal shareholders, executive officers, and directors, or their
  affiliates, directly or indirectly, as of June 30, 1994, was $775,334, or
  approximately 3.7% of shareholders' equity at such date.

       No loans to any director or executive officer of ARBI or the Bank or any
  of the respective "associates" of such person are past due, or 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 ARBI owned
  a total of 78,818.9 shares of ARBI Common Stock, representing approximately
  19.2% 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 ARBI Common
  Stock held by the other ARBI shareholders.  Each of the directors and
  executive officers of ARBI has separately indicated his intention to vote in
  favor of the Merger.

       Mr. Foley, the President of ARBI, is currently a party to three
  agreements with either or both of ARBI and the Bank that provide for payments
  to him in the event of a change of control of ARBI or the Bank or if his
  employment with such companies ceases after a change of control.  These
  agreements are (i) the Executive Supplemental Income Agreement dated October
  2, 1989, as amended May 12, 1994, between the Bank and Mr. Foley (the
  "Supplemental Agreement"), (ii) the Employment Agreement dated January 14,
  1992, as amended May 12, 1994, among Mr. Foley, ARBI, and the Bank (the
  "Employment Agreement"), and (iii) the Performance Share Incentive Bonus Plan
  dated December 21, 1993, between Mr. Foley and ARBI (the "Plan").
  Additionally, Mr. Wiser, the Executive Vice President and Chief Operating
  Officer of the Bank and an executive officer of ARBI, is a party to an
  Executive Supplemental Income Agreement dated October 26, 1989, as amended
  October 8, 1993 (the "Wiser Agreement"), which provides for payments to Mr.
  Wiser in the event his employment with such companies ceases after a change in
  control.  The material terms of each of these agreements are summarized below.

       THE SUPPLEMENTAL AGREEMENT AND THE WISER AGREEMENT

       In October 1989 the Bank entered in to the Supplemental Agreement with
  Mr. Foley, and entered into the Wiser Agreement with Mr. Wiser, in order to
  provide supplemental retirement benefits to such executives.  The Supplemental
  Agreement and the Wiser Agreement provide generally that, if the executive has
  been continuously employed by the Bank, at age 65 the executive will receive
  an annual retirement benefit calculated in accordance with such agreement.
  The amount of the current annual post-retirement benefits payable to Messrs.
  Foley and Wiser would be equal to 37% of their respective salaries as of the
  date of retirement.  The Supplemental Agreement and the Wiser Agreement permit
  early retirement with full benefits upon approval of the Board of Directors of
  the Bank after the age of 55 if the executive has completed 15 years of
  service.  The agreements also provide for death benefits over a term of years
  in the event of death prior to retirement age.

                                      87
<PAGE>
 
       If after a change of control of the Bank, however, the executive
  voluntarily terminates his employment or is fired without cause (as defined in
  the agreement), or becomes permanently disabled, the executive's actuarially
  determined benefits under the agreement become fully vested and
  nonforfeitable.  Generally, the amount of the executive's actuarially
  determined benefits is equal to the amount of benefits otherwise payable to
  the executive multiplied by the ratio that the executive's years of actual
  service bears to the total number of possible years of service from the date
  of employment to age 65.  In addition, after a change of control of the Bank
  the Supplemental Agreement and the Wiser Agreement each permit the executive
  to retire at age 55, rather than 65, without satisfying any minimum years of
  service or obtaining board approval.  For Messrs. Foley and Wiser, these
  amounts currently would be $21,824 and $2,422, respectively, which their
  agreements would require to be paid in ratable monthly installments over a 
  15-year period.

       At ARBI's annual meeting of shareholders held in April 1994, the
  shareholders ratified and approved the terms of the Supplemental Agreement.
  Subsequent to such ratification, ARBI and Mr. Foley amended the Supplemental
  Agreement to limit Mr. Foley's compensation thereunder and under the
  Employment Agreement (defined below), in the event of a change of control, to
  299% of his base salary, as defined by IRS regulation, in order to avoid any
  possibility that the IRS could successfully challenge the deductibility of the
  payments by ARBI to Mr. Foley thereunder.

       THE EMPLOYMENT AGREEMENT

       ARBI and Mr. Foley entered into the Employment Agreement in 1992.  This
  agreement initially provided for the employment of Mr. Foley through February
  28, 1995, subject to automatic one-year renewals commencing March 1, 1993,
  unless three months prior notice of nonrenewal is given by either party.
  Accordingly, the Employment Agreement currently provides for the employment of
  Mr. Foley through February 28, 1997, unless his employment is terminated prior
  to that time by ARBI for cause (generally, conduct that involves dishonesty or
  moral turpitude in connection with his employment or that is demonstrably and
  materially injurious to the financial condition of ARBI) or for any other
  reason.  Mr. Foley may also terminate his employment for good reason
  (generally, the acquisition by any other person of all or substantially all of
  the business of ARBI or the Bank, other than one arranged by a government
  agency) or for any other reason.  The Merger will constitute good reason
  within the meaning of the Employment Agreement.

       In the event that ARBI terminates Mr. Foley's employment for cause, it is
  liable to Mr. Foley only for the payment of amounts of salary, incentive
  compensation, benefits, and expense reimbursements earned but unpaid at the
  date of termination.  If, however, ARBI terminates Mr. Foley's employment
  other than for cause, Mr. Foley will receive his salary and benefits for a
  six-month period after termination.

       Should an acquisition giving rise to good reason occur, Mr. Foley is
  permitted to terminate his employment prior to any termination by ARBI and, in
  such event, Mr. Foley will receive his salary and benefits for the remaining
  term of the agreement.  If such events were to have occurred as of December
  31, 1994, Mr. Foley would have been entitled to (i) receive an annual salary
  of $163,887 through February 28, 1997, and (ii) continue to participate in all
  employee benefit programs through such date.  If, however, Mr. Foley
  terminates his employment other than for good reason, ARBI has no further
  obligation to Mr. Foley other than to pay to him the salary, incentive
  compensation, benefits, and expense reimbursements earned but unpaid on the
  date of termination.

       At ARBI's annual meeting of shareholders held in April 1994, the
  shareholders ratified and approved the terms of the Employment Agreement.
  Subsequent to such ratification, ARBI and Mr. 

                                      88
<PAGE>
 
  Foley amended the Employment Agreement to limit Mr. Foley's compensation
  thereunder and under the Supplemental Agreement, in the event of a change of
  control, to 299% of his base salary, as defined by IRS regulation, in order to
  avoid any possibility that the IRS could successfully challenge the
  deductibility of the payments by ARBI to Mr. Foley thereunder.

       THE PERFORMANCE SHARE INCENTIVE BONUS PLAN

       Pursuant to the Plan, Mr. Foley was granted 20,000 "performance shares"
  as of January 1, 1993 (the "Determination Date").  A performance share is a
  monetary amount equal to the difference between the fair market value of one
  share of common stock of the Bank on the date the performance shares are
  exercised and the value of one share of common stock of the Bank on the
  Determination Date.  The fair market value of one share of common stock of the
  Bank is determined in good faith by the Board of Directors of ARBI in its sole
  discretion.  As of the Determination Date, the Board of Directors of ARBI
  determined such value to be $40.50.

       The performance shares vest ratably over a five-year period, but become
  fully vested immediately upon certain events, such as the termination of Mr.
  Foley's employment due to his death or disability or the sale or change of
  control of the Bank.  For purposes of the Plan, the Bank is considered to have
  been sold if 80% or more of the common stock of the Bank or ARBI, or if 80% or
  more of the assets of the Bank, is sold or exchanged to persons not
  shareholders of ARBI as of December 21, 1993.  A "change of control" will be
  deemed to have occurred for purposes of the Plan if more than 50% of the
  common stock of the Bank or ARBI is sold or exchanged to persons not
  shareholders of ARBI as of December 21, 1993.  The Merger will constitute a
  "change of control" within the meaning of the Plan.

       In the event of a sale of the Bank or a change of control within the
  meaning of the plan occurs, ARBI is obligated to purchase the vested shares
  held by Mr. Foley, or in the event of his death, by his estate, heirs or
  devisees, 180 days after the first to occur of (i) the termination of Mr.
  Foley's employment by ARBI or the Bank or (ii) the sale or change of control,
  of the Bank.  Consequently, as a result of the Merger, ARBI estimates that Mr.
  Foley will become entitled to receive from ARBI within 180 days after the
  Effective Time of the Merger a cash payment of $642,720.

      The terms of the Plan were ratified and approved by the shareholders of
  ARBI at the annual meeting of shareholders held April 19, 1994.

                       CERTAIN REGULATORY CONSIDERATIONS

  GENERAL

      As a bank holding company, Norwest is subject to supervision and
  examination by the Federal Reserve Board.  Norwest's banking subsidiaries are
  subject to supervision and examination by applicable federal and state banking
  agencies.  The deposits of Norwest's banking subsidiaries are insured by the
  Bank Insurance Fund of the Federal Deposit Insurance Corporation ("FDIC"), and
  therefore such banking subsidiaries are subject to regulation by the FDIC.  In
  addition to the impact of regulation, commercial banks are affected
  significantly by the actions of the Federal Reserve Board as it attempts to
  control the money supply and credit availability in order to influence the
  economy.

  DIVIDEND RESTRICTIONS

      Various federal and state statutes and regulations limit the amount of
  dividends the subsidiary banks can pay to Norwest without regulatory approval.
  The approval of the OCC is required for any dividend by a national bank if the
  total of all dividends declared by the bank in any calendar year would exceed
  the total of its net profits, as defined by regulation, for that year combined
  with its retained net profits for the preceding two years less any required
  transfers to surplus or a fund for the retirement of any preferred stock.  In
  addition, a national bank may not pay a dividend in an amount greater than its
  net profits then on hand after deducting its losses and bad debts.  For this
  purpose, bad debts are defined to include, generally, loans which have matured
  and are in arrears with respect to interest by six months or more, other than
  such loans which are well secured and in the process of collection.  Under
  these provisions Norwest's national bank subsidiaries could have declared, as
  of June 30, 1994, aggregate dividends of at least $384.2 million without
  obtaining prior regulatory approval and without reducing the capital of the
  banks below their respective minimum levels.  Norwest also has several state
  bank subsidiaries that are subject to state regulations limiting dividends;
  however, the amount of dividends payable by Norwest's state bank subsidiaries,
  with or without state regulatory approval, would represent an immaterial
  contribution to Norwest's revenues.

      If, in the opinion of the applicable regulatory authority, a bank under
  its jurisdiction is engaged in or is about to engage in an unsafe or unsound
  practice (which, depending on the financial condition of the bank, could
  include the payment of dividends), such authority may require, after notice
  and hearing, that such bank cease and desist from such practice.  The Federal
  Reserve Board, the OCC, and the FDIC have issued policy statements which
  provide that FDIC-insured banks and bank holding companies should generally
  pay dividends only out of current operating earnings.

  HOLDING COMPANY STRUCTURE

      Norwest is a legal entity separate and distinct from its banking and
  nonbanking subsidiaries.  Accordingly, the right of Norwest, and thus the
  rights of Norwest's creditors, to participate in any distribution of the
  assets or earnings of any subsidiary is necessarily subject to the prior
  claims of creditors of such subsidiary, except to the extent that claims of
  Norwest in its capacity as a creditor may be recognized.  The principal
  sources of Norwest's revenues are dividends and fees from its subsidiaries.

      Norwest's banking subsidiaries are subject to restrictions under federal
  law which limit the transfer of funds by the subsidiary banks to Norwest and
  its nonbanking subsidiaries, whether in the form of loans, extensions of
  credit, investments, or asset purchases.  Such transfers by any 

                                      90
<PAGE>
 
  subsidiary bank to Norwest or any nonbanking subsidiary are limited in amount
  to 10% of the bank's capital and surplus and, with respect to Norwest and all
  such nonbanking subsidiaries, to an aggregate of 20% of such bank's capital
  and surplus. Furthermore, such loans and extensions of credit are required to
  be secured in specified amounts.

      The Federal Reserve Board has a policy to the effect that a bank holding
  company is expected to act as a source of financial and managerial strength to
  each of its subsidiary banks and to commit resources to support each such
  subsidiary bank.  This support may be required at times when Norwest may not
  have the resources to provide it.  Any capital loans by Norwest to any of the
  subsidiary banks are subordinate in right of payment to deposits and to
  certain other indebtedness of such subsidiary bank.  In addition, the Crime
  Control Act of 1990 provides that in the event of a bank holding company's
  bankruptcy, any commitment by the bank holding company to a federal bank
  regulatory agency to maintain the capital of a subsidiary bank will be assumed
  by the bankruptcy trustee and entitled to a priority of payment.

      A depository institution insured by the FDIC can be held liable for any
  loss incurred by, or reasonably expected to be incurred by, the FDIC after
  August 9, 1989, in connection with (i) the default of a commonly controlled
  FDIC-insured depository institution or (ii) any assistance provided by the
  FDIC to a commonly controlled FDIC-insured depository institution in danger of
  default.  "Default" is defined generally as the appointment of a conservator
  or receiver and "in danger of default" is defined generally as the existence
  of certain conditions indicating that a "default" is likely to occur in the
  absence of regulatory assistance.

      Federal law (12 U.S.C. (S)55) permits the OCC to order the pro rata
  assessment of shareholders of a national bank whose capital stock has become
  impaired, by losses or otherwise, to relieve a deficiency in such national
  bank's capital stock.  This statute also provides for the enforcement of any
  such pro rata assessment of shareholders of such national bank to cover such
  impairment of capital stock by sale, to the extent necessary, of the capital
  stock of any assessed shareholder failing to pay the assessment.  Similarly,
  the laws of certain states provide for such assessment and sale with respect
  to banks chartered by such states.  Norwest, as the sole shareholder of
  certain of its subsidiary banks, is subject to such provisions.

  CAPITAL REQUIREMENTS

      Under the Federal Reserve Board's risk-based capital guidelines for bank
  holding companies, the minimum ratio of total capital to risk-adjusted assets
  (including certain off-balance sheet items, such as stand-by letters of
  credit) is 8%.  At least half of the total capital is to be comprised of
  common stock, minority interests, and noncumulative perpetual preferred stock
  ("Tier 1 capital").  The remainder ("Tier 2 capital") may consist of hybrid
  capital instruments, perpetual debt, mandatory convertible debt securities, a
  limited amount of subordinated debt, other preferred stock, and a limited
  amount of loan and lease loss reserves.  In addition, the Federal Reserve
  Board's final minimum "leverage ratio" (the ratio of Tier 1 capital to
  quarterly average total assets) guidelines for bank holding companies provide
  for a minimum leverage ratio of 3% for bank holding companies that meet
  certain specified criteria, including that they have the highest regulatory
  rating.  All other bank holding companies are required to maintain a leverage
  ratio of 3% plus an additional cushion of 100 to 200 basis points.  The
  guidelines also provide that banking organizations experiencing internal
  growth or making acquisitions will be expected to maintain strong capital
  positions substantially above the minimum supervisory levels, without
  significant reliance on intangible assets.  Furthermore, the guidelines
  indicate that the Federal Reserve Board will continue to consider a "tangible
  Tier 1 leverage ratio" in evaluating proposals for expansion or new
  activities.  The tangible Tier 1 leverage ratio is the ratio of a banking
  organization's Tier 1 capital, less all intangibles, to total assets, less all
  intangibles.  Each of Norwest's banking 

                                      91
<PAGE>
 
  subsidiaries is also subject to capital requirements adopted by applicable
  regulatory agencies which are substantially similar to the foregoing. At June
  30, 1994, Norwest's Tier 1 and total capital (the sum of Tier 1 and Tier 2
  capital) to risk-adjusted assets ratios were 10.00% and 12.40%, respectively,
  and Norwest's leverage ratio for the quarter ended June 30, 1994, was 6.85%.
  Neither Norwest nor any subsidiary bank has been advised by the appropriate
  federal regulatory agency of any specific leverage ratio applicable to it.

  FEDERAL DEPOSIT INSURANCE CORPORATION IMPROVEMENT ACT OF 1991

      In December 1991, Congress enacted the Federal Deposit Insurance
  Corporation Improvement Act of 1991 ("FDICIA"), which substantially revised
  the bank regulatory and funding provisions of the Federal Deposit Insurance
  Act and makes revisions to several other federal banking statutes.  Among
  other things, FDICIA requires the federal banking regulators to take "prompt
  corrective action" in respect of FDIC-insured depository institutions that do
  not meet minimum capital requirements.  FDICIA establishes five capital tiers:
  "well capitalized," "adequately capitalized," "undercapitalized,"
  significantly undercapitalized," and "critically undercapitalized."  Under
  applicable regulations, an FDIC-insured depository institution is defined to
  be well capitalized if it maintains a leverage ratio of at least 5%, a risk-
  adjusted Tier 1 capital ratio of at least 6%, and a risk-adjusted total
  capital ratio of at least 10%, and is not subject to a directive, order, or
  written agreement to meet and maintain specific capital levels.  An insured
  depository institution is defined to be adequately capitalized if its meets
  all of its minimum capital requirements as described above.  An insured
  depository institution will be considered undercapitalized if it fails to meet
  any minimum required measure, significantly undercapitalized if it has a risk-
  adjusted total capital ratio of less than 6%, risk-adjusted Tier 1 capital
  ratio of less than 3%, or a leverage ratio of less than 3%, and critically
  undercapitalized if it fails to maintain a level of tangible equity equal to
  at least 2% of total assets.  An insured depository institution may be deemed
  to be in a capitalization category that is lower than is indicated by its
  actual capital position if it receives an unsatisfactory examination rating.

      FDICIA generally prohibits a depository institution from making any
  capital distribution (including payment of a dividend) or paying any
  management fee to its holding company if the depository institution would
  thereafter be undercapitalized.  Undercapitalized depository institutions are
  subject to a wide range of limitations on operations and activities, including
  growth limitations, and are required to submit a capital restoration plan.
  The federal banking agencies may not accept a capital plan without
  determining, among other things, that the plan is based on realistic
  assumptions and is likely to succeed in restoring the depository institution's
  capital.  In addition, for a capital restoration plan to be acceptable, the
  depository institution's parent holding company must guarantee that the
  institution will comply with such capital restoration plan.  The aggregate
  liability of the parent holding company is limited to the lesser of (i) an
  amount equal to 5% of the depository institution's total assets at the time it
  became undercapitalized and (ii) the amount which is necessary (or would have
  been necessary) to bring the institution into compliance with all capital
  standards applicable with respect to such institution as of the time it fails
  to comply with the plan.  If a depository institution fails to submit an
  acceptable plan, it is treated as if it were significantly undercapitalized.

      Significantly undercapitalized depository institutions may be subject to a
  number of requirements and restrictions, including orders to sell sufficient
  voting stock to become adequately capitalized, requirements to reduce total
  assets, and cessation of receipt of deposits from correspondent banks.
  Critically undercapitalized institutions are subject to the appointment of a
  receiver or conservator.

                                      92
<PAGE>
 
       FDICIA directs that each federal banking agency prescribe standards for
  depository institutions and depository institution holding companies relating
  to internal controls, information systems, internal audit systems, loan
  documentation, credit underwriting, interest rate exposure, asset growth,
  compensation, a maximum ratio of classified assets to capital, minimum
  earnings sufficient to absorb losses, a minimum ratio of market value to book
  value for publicly traded shares, and such other standards as the agency deems
  appropriate.  The FDIC, in consultation with the other federal banking
  agencies, has adopted a final rule and guidelines with respect to external and
  internal audit procedures and internal controls in order to implement those
  provisions of FDICIA intended to facilitate the early identification of
  problems in financial management of depository institutions.  The FDIC has
  also issued proposed rules prescribing standards relating to certain other of
  the management and operational standards listed above.  The full impact of
  such rule and guidelines and proposed standards on Norwest cannot yet be
  ascertained.

      FDICIA also contains a variety of other provisions that may affect the
  operations of Norwest, including new reporting requirements, revised
  regulatory standards for real estate lending, "truth in savings" provisions,
  and the requirement that a depository institution give 90 days' notice to
  customers and regulatory authorities before closing any branch.

      Under other regulations promulgated under FDICIA a bank cannot accept
  brokered deposits (that is, deposits obtained through a person engaged in the
  business of placing deposits with insured depository institutions or with
  interest rates significantly higher than prevailing market rates) unless (i)
  it is "well capitalized" or (ii) it is "adequately capitalized" and receives a
  waiver from the FDIC.  A bank is defined to be "adequately capitalized" if it
  meets all of its minimum capital requirements.  A bank that cannot receive
  brokered deposits also cannot offer "pass-through" insurance on certain
  employee benefit accounts, unless it provides certain notices to affected
  depositors.  In addition, a bank that is "adequately capitalized" and that has
  not received a waiver from the FDIC may not pay an interest rate on any
  deposits in excess of 75 basis points over certain prevailing market rates.
  There are no such restrictions on a bank that is "well capitalized."  At June
  30, 1994, all of Norwest's banking subsidiaries were well capitalized and
  therefore were not subject to these restrictions.

  FDIC INSURANCE

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

(1) Changes in Accounting Policy
    ----------------------------

    During 1993, American Republic Bancshares, Inc. (the Company) adopted
     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.  The change in method of accounting for
     income taxes resulting from adoption of SFAS 109 had no significant effect
     on the accompanying financial statements.

    Effective January 1, 1994, the Company adopted Statement of Financial
     Accounting Standards No. 115, "Accounting for Certain Investments in Debt
     and Equity Securities," (FAS 115).  Accordingly, beginning on January 1,
     1994, pursuant to the Company'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 as a
     separate component of stockholders' equity.  On January 1, 1994, the
     Company recorded an increase of $1,970,000, net of tax, in stockholders'
     equity.  The remaining securities are deemed to be held to maturity and are
     reported at amortized cost.  On January 1, 1994 net unrealized gains on
     securities held to maturity were approximately $3,633,000.  Premiums and
     discounts on both securities available for sale and held to maturity are
     amortized/accreted to interest income on investment securities using the
     effective interest method over the term of the security.

    Prior to the adoption of FAS 115, investment securities are reported at
     amortized cost.

    Realized gains and losses on the sale of investment securities are
     recognized using the identified certificate method.

(5)  Executive Incentive and Employment Agreements
     ---------------------------------------------

     In April 1994, the Company's stockholders approved a performance share
      incentive bonus plan (Plan) for its President. This Plan grants stock
      appreciation rights to the President, which, if fully vested, would have a
      value of approximately $670,000 at June 30, 1994. These rights vest
      ratably over a five year period beginning January 1, 1993, but become
      fully vested immediately upon certain events such as the termination of
      the President's employment due to his death or disability or the sale or
      change of control of the Company.

     A vested benefit of approximately $134,000 accrued to the President upon
      stockholder approval of the Plan. Such vested benefit is reflected in
      accrued expenses as of June 30, 1994, and in salaries and employee
      benefits expense during the three and six month periods then ended.

     The Company also has an employment agreement (Agreement) with its
      President. The Agreement includes a provision that if any other
      corporation or entity acquires the Company (unless such acquisition is
      arranged or assisted by a government agency), the President may, at his
      option, terminate his employment and receive from the Company up to three
      years annual compensation, which would approximate $500,000.

The Board of Directors
American Republic Bancshares, Inc.:


We have audited the accompanying consolidated balance sheets of American
Republic Bancshares, Inc. and subsidiary as of December 31, 1993 and 1992, and
the related consolidated statements of operations, changes in stockholders'
equity and cash flows for the years then ended.  These consolidated financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of American Republic
Bancshares, Inc. and subsidiary at December 31, 1993 and 1992, and the results
of their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles.

                   Notes to Consolidated Financial Statements

                           December 31, 1993 and 1992



(1)  Summary of Significant Accounting Policies

     The accounting policies of American Republic Bancshares, Inc. (Bancshares)
       and subsidiary (collectively referred to as the Company) conform to
       generally accepted accounting principles and to general practice within
       the banking industry. The following is a summary of the more significant
       of those policies:

     (a)  Basis of Presentation

          The consolidated financial statements include Bancshares and its
            wholly-owned subsidiary, First National Bank of Belen (Bank).

          All significant intercompany balances and transactions have been
            eliminated in consolidation.

     (b)  Investment Securities

          Investment securities are stated at cost, adjusted for amortization of
            premiums and accretion of discounts.  The lower of cost or market is
            not used for securities valuation since the Bank has the ability and
            intent to hold the securities to maturity, except that costs of
            individual securities are written down to market when the ultimate
            realization of the recorded amounts is not reasonably assured. Gains
            or losses on the sale of investment securities are recognized using
            the identified certificate method.

     (c)  Allowance for Loan Losses

          Loan losses are charged to the allowance for loan losses and
            recoveries are credited to it. The provision for loan losses charged
            to expense is based on past loan loss experience, management's
            evaluation of the loan portfolio and other factors which, in
            management's judgment, deserve current recognition in estimating
            possible loan losses. Such other factors considered by management
            include growth and composition of the loan portfolio, the
            relationship of the allowance for loan losses to outstanding loans,
            collateral values and economic conditions. The determination of the
            allowance for loan losses and the valuation of real estate in
            connection with the satisfaction of loans are material estimates
            that are susceptible to change in the near term. Management does,
            however, obtain independent appraisals for significant properties
            that secure loans.



                                                                     (Continued)

                       AMERICAN REPUBLIC BANCSHARES, INC.
                                 AND SUBSIDIARY

                   Notes to Consolidated Financial Statements


        A substantial portion of the Bank's loans are secured by real estate,
          primarily in New Mexico.  The ultimate collectibility of a substantial
          portion of the Bank's loan portfolio is therefore susceptible to
          changes in real estate market conditions.

        Management believes that the allowance for losses on loans is
          adequate.  While management uses available information to recognize
          losses on loans, future additions to the allowance may be necessary
          based on changes in economic conditions.  In addition, various
          regulatory agencies, as an integral part of their examination process,
          periodically review the Bank's allowance for losses on loans.  Such
          agencies may require the Bank to adjust the allowance based on their
          judgments about information available to them at the time of their
          examination.

   (d)  Income on Loans

        Interest is accrued on loans unless, in the opinion of management,
          collectibility of the interest is not probable.  When accrual of
          interest is discontinued, any previously accrued uncollected interest
          is charged against interest income.  Interest received on nonaccrual
          loans is applied as a reduction of principal if there is doubt as to
          the collectibility in full of the outstanding balance.

        Unearned interest on installment loans is amortized into income in
          amounts that approximate the interest method.

        Loan origination fees and direct costs of originating loans are
          amortized into income over the lives of the loans using a method that
          approximates the interest method.

   (e)  Premises and Equipment

        Premises and equipment are stated at cost less accumulated
          depreciation.  Depreciation is computed using the straight-line and
          declining-balance methods over the estimated useful lives of the
          assets.

        Maintenance and repairs are charged to expense in the year incurred.
          Renewals and material betterments are capitalized.  Gains or losses on
          dispositions are credited or charged to income.

   (f)  Other Real Estate

        Other real estate is comprised of foreclosed properties where the Bank
          has actually received title or which are "in-substance" foreclosures.
          Loans are classified as in-substance foreclosures when the bank
          receives physical possession of the borrower's collateral even though
          formal foreclosure proceedings may not have

                                                                     (Continued)

          taken place.  Such properties are carried at the lower of the
          investment in the related loan or estimated net realizable value.  The
          fair value of such properties is determined based on independent
          appraisals and other relevant factors.

        Any writedowns required prior to or at the time of acquisition are
          charged against the allowance for loan losses.

        Declines in value, subsequent to acquisition, are accounted for as a
          charge to losses on other real estate and are included in other
          expenses in the period in which a decline in value is determined.
          Operating expenses, including rental or lease income and depreciation,
          and gains or losses from sales of other real estate are charged or
          credited to other operating expenses or income as incurred.

   (g)  Excess of Cost Over Net Assets of Subsidiary

          The excess of cost over net assets of the subsidiary is amortized
          using the straight-line method over 20 years.

   (h)  Income Taxes

        In February 1992, the Financial Accounting Standards Board issued
          Statement of Financial Accounting Standards No. 109, Accounting for
          Income Taxes.  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 1993, the Company adopted Statement 109. The change in method
          of accounting for income taxes had no significant effect.

        Bancshares files consolidated federal and state income tax returns
          with its subsidiary.

                   Notes to Consolidated Financial Statements

   (i)  Statement of Cash Flows

        For purposes of reporting cash flows, cash and cash equivalents
          include cash and due from banks and federal funds sold.

   (j)  Recent Accounting Pronouncements

        The Financial Accounting Standards Board has issued Statement 114
          (FASB No. 114), "Accounting by Creditors for Impairment of a Loan."
          The Statement applies to all creditors and all loans, including those
          that are restructured in troubled debt restructuring 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.  The Statement requires applicable loans 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
          Statement is effective for fiscal years beginning after December 15,
          1994, with earlier application encouraged.  The Bank has not decided
          whether or not this Statement will be applied early, nor have the
          effects of this Statement been evaluated.

        In May 1993, the Financial Accounting Standards Board (FASB) issued
          Statement of Financial Accounting Standards (SFAS) No. 115,
          "Accounting for Certain Investments in Debt and Equity Securities."
          Adoption of SFAS No. 115 is required for fiscal years beginning after
          December 15, 1993, with early adoption permitted.  The Company adopted
          the new standard effective January 1, 1994.  Certain securities at
          January 1, 1994 are deemed by management to be available for sale and,
          in accordance with SFAS No. 115, are reported at fair value (based on
          quoted market prices) with net unrealized gains and losses reported as
          a separate component of stockholders' equity.  At January 1, 1994, the
          Company recorded an increase of $1,970,000, net of tax, in
          stockholders' equity.  The remaining securities are deemed by
          management to be held-to-maturity and are therefore reported at
          amortized cost.

   (k)  Reclassifications

        Certain 1992 amounts have been reclassified to conform with the 1993
          financial statement presentation.

(10) Employee Benefit Plans

     The Company has a defined benefit pension plan covering substantially all
       of its employees. Prior to 1989, the benefits were based on years of
       service and the employee's highest consecutive 5-years compensation
       during the last 10 years of service. The Plan was amended, effective
       January 1, 1989, to provide a monthly retirement benefit of .75 percent
       of a participant's career average compensation multiplied by the years of
       service with a minimum monthly benefit of $5.00 multiplied by the years
       of service up to 40 years. Vesting occurs on a graduating basis, with
       full vesting achieved at the end of 7 years. The Company's funding policy
       is to annually contribute amounts necessary to maintain substantially
       full funding. The Company contributed $47,609 and $46,701 during the
       years ending December 31, 1993 and 1992, respectively, to this plan.

    At December 31, 1993, the fair value of the Plan's assets of $370,683
      (consisting primarily of cash and cash equivalents, U.S. government
      securities and mutual funds) exceeded the Plan's accumulated benefit
      obligation of $209,767. The weighted average discount rate used in
      projecting the accumulated benefit obligation was 8.0 percent and the
      expected long-term rate of return on assets and rate of increase in future
      compensation levels were 8.5 percent and 5.0 percent, respectively. Net
      periodic pension costs incurred were $32,948 and $4,890 in 1993 and 1992,
      respectively.


                                                                     (Continued)

                   Notes to Consolidated Financial Statements


   The Company also has a 401(k) savings plan under which the Company may
     match a portion of the employee's contribution up to 100 percent based on
     return on average assets, and a profit-sharing plan under which the Company
     may make contributions of up to 15 percent of the employee's compensation.
     Participation is available to substantially all employees.  Vesting occurs
     on a graduating basis, with full vesting achieved at the end of 7 years.
     The Company may terminate either plan at any time.  The Company contributed
     $27,238 and $24,147 to this plan in 1993 and 1992, respectively.

   The Company also has an Employee Stock Ownership Plan (ESOP) for
     substantially all of its employees.  Total shares allocated to participants
     is based upon the employer's annual contribution.  Such shares are
     allocated to individual participants based on the ratio of each
     participant's compensation to total participants' compensation.  Vesting
     occurs on a graduating basis with full vesting achieved at the end of 7
     years.  The ESOP obtained a loan from an unrelated bank (note 8) that was
     used to purchase 13,513 outstanding shares of common stock from a
     stockholder.  Contributions made by the Company to the ESOP are intended to
     pay principal and interest on the ESOP debt and, in turn, allocate a
     proportionate amount of the ESOP common stock shares to the participating
     employees.  Any dividends on unallocated shares are also used to pay
     principal, interest and plan expenses.  The ESOP debt is guaranteed by
     Bancshares and, therefore, is presented as long-term debt and a reduction
     of stockholders' equity.  The Company contributed $108,744 and $63,160 to
     the ESOP of which $17,545 and $20,981 was attributable to interest on the
     ESOP debt for the years ending December 31, 1993 and 1992, respectively.

   The Company also has a supplemental benefit plan designed to provide
     certain employees with supplemental retirement benefits.  The plan was
     funded with a single contribution of $755,000.  Benefits accrue to the
     employees over their employment and will provide the employees with salary
     continuation benefits upon retirement or death.  As part of the plan, the
     Company has obtained insurance contracts on the plan participants in
     amounts sufficient to discharge the Company's obligations under the plan.
     Other assets include $752,651 and $1,065,798 at December 31, 1993 and 1992,
     respectively, of cash surrender value for the insurance contracts
     purchased; and accrued liabilities include $47,733 and $40,666 relating to
     benefits for the years ending December 31, 1993 and 1992, respectively.
     The Company recorded an expense of $13,635 and $3,241 in 1993 and 1992,
     respectively, for benefits accruing under this plan.

   The Company also has a compensation arrangement with its president whereby
     under certain circumstances it may incur an obligation to this individual
     of up to 3 years annual compensation, which would approximate $500,000.

                                                                     (Continued)

(11) Dividend Restrictions

     Undivided profits of the Bank include $13,000,000 not available for
       dividends to its stockholder because of regulatory requirements.

(12) Risk-based Capital and Leverage Ratios

     In January 1989, the Federal Reserve Board and the Office of the
       Comptroller of the Currency issued guidelines which establish a risk-
       adjusted ratio relating capital to various categories of recorded assets
       and off-balance sheet commitments adjusted for relative credit risk.  The
       guidelines require a minimum total risk-based capital ratio of 8.0
       percent. At December 31, 1993, Bancshares' total risk-based capital ratio
       was 18.35 percent.

     In early 1990, the Federal Reserve Board proposed a new minimum leverage
       ratio representing the minimum capital to total assets standard for
       banking organizations. The minimum leverage ratio required for those
       banks with the highest regulatory rating is 3.00 percent. At December 31,
       1993, Bancshares' leverage ratio was 8.53 percent.

(13) Fair Value of Financial Instruments

     Statement of Financial Accounting Standards No. 107, "Disclosures About
       Fair Value of Financial Instruments" (FAS 107) requires that Bancshares
       disclose estimated fair values for its financial instruments. Fair value
       estimates are made at a specific point in time, based on relevant market
       information and information about the financial instrument. These
       estimates do not reflect any premium or discount that could result from
       offering for sale at one time Bancshares' entire holdings of a particular
       financial instrument. Because no market exists for a significant portion
       of Bancshares' financial instruments, fair value estimates are based on
       judgments regarding future expected loss experience, current economic
       conditions, risk characteristics of various financial instruments and
       other factors. These estimates are subjective in nature and involve
       uncertainties and matters of significant judgment and therefore cannot be
       determined with precision. Changes in assumptions could significantly
       affect the estimates.

     Fair value estimates are based on existing on and off-balance sheet
       financial instruments without attempting to estimate the value of
       anticipated future business and the value of assets and liabilities that
       are not considered financial instruments.  Significant assets



                                                                     (Continued)

                   Notes to Consolidated Financial Statements


       and liabilities that are not considered financial assets or liabilities
       include premises and equipment and other real estate owned. In addition,
       the tax ramifications related to the realization of the unrealized gains
       and losses can have a significant effect on fair value estimates and have
       not been considered in the estimates.

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

       Cash, Short-term Investments and Short-term Borrowings:
       The fair value of the short-term instruments approximates the carrying
         amounts because they mature in 90 days or less.

       Investment Securities:
       The fair value of securities is based on quoted market prices or dealer
         quotes, if available. If a quoted market price for a specific security
         is not available, fair value is estimated using quoted market prices
         for similar securities.

       Loans:
       The fair value of loans is estimated by discounting the anticipated cash
         flows using appropriate current discount rates to determine their
         present value. The yield on the U.S. Treasury security having a term
         which most closely corresponds to the term of the loan is the risk-free
         discount rate used. The risk-free rate is adjusted for the operating
         expense component and the estimated credit quality component, which is
         the annualized yield needed to cover the expected loan losses. The
         credit quality component is based on an analysis of under performing
         loans and gross charge-off experience.

       Deposit Liabilities:
       The fair value of deposits with no stated maturity, such as demand
         deposits, savings accounts, NOW accounts and money market deposits is
         the amount payable on demand at the reporting date. The fair value of
         fixed-maturity certificates of deposit is based on the discounted
         anticipated cash flows using the appropriate risk free discount rate
         adjusted for the estimated credit quality relating to the "market view"
         of the creditworthiness of the institution based on selected financial
         ratios and the operating expense component.



                                                                     (Continued)

                   Notes to Consolidated Financial Statements


     Long-term Debt:
     The fair value of long-term debt approximates the carrying amount as the
       majority of the debt is tied to floating interest rates thereby repricing
       the debt at current market values on a continual basis.

     The estimated fair values of Bancshares' financial instruments are as
       follows:

(14) Condensed Financial Information of Parent Company

     The assets of Bancshares consist primarily of an investment in its
       subsidiary bank and the Bank's operating facilities. As discussed in note
       11, dividends paid by the Bank are limited by bank regulatory agencies.
       The principal source of Bancshares' revenue is dividends from the
       subsidiary bank, which are utilized for payments of debt service,
       operating costs and dividends to Bancshare stockholders. Condensed

                   Notes to Consolidated Financial Statements


(15) Regulatory Matters

     In June 1992, the Board of Directors of the Bank entered into a Memorandum
       of Understanding (Memorandum) with the Office of the Comptroller of the
       Currency (OCC) that required the Bank to take a number of actions to
       strengthen the Bank's financial condition and required the approval of 
       the OCC prior to the declaration or payment of any dividends.

     The OCC conducted an examination of the Bank as of December 31, 1993, which
       disclosed that the overall condition of the Bank was satisfactory and
       that the Bank was in substantial compliance with the Memorandum. As a
       result, the Memorandum was terminated on March 15, 1994.

(16) Legal Proceedings

     The Company is party to various legal proceedings in the normal course of
       business.  In management's opinion, after consultation with outside legal
       counsel, the disposition of these matters will not materially affect the
       financial position of the Company.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------
                                        



The Board of Directors
American Republic Bancshares, Inc.:


We have audited the accompanying consolidated balance sheets of American
Republic Bancshares, Inc. and subsidiaries as of December 31, 1992 and 1991, and
the related consolidated statements of operations, changes in stockholders'
equity and cash flows for the years then ended.  These consolidated financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of American Republic
Bancshares, Inc. and subsidiaries at December 31, 1992 and 1991, and the results
of their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles.

As discussed in note 15 to the consolidated financial statements, the Board of
Directors of the Bank entered into a Memorandum of Understanding (Memorandum)
with the Office of the Comptroller of the currency (OCC) in June 1992 that
required the Bank to take a number of actions to strengthen the Bank's financial
condition.  Since the implementation of the Memorandum, the OCC conducted
another on-site examination as of November 30, 1992.  The OCC has indicated in a
draft examination report that the Bank's overall compliance with the Memorandum
is not yet at a desirable level.  As a result, the Memorandum will remain in
effect until terminated by the OCC.  Failure to obtain total compliance with the
Memorandum in a timely manner could result in additional administrative action
by the OCC.

                   Notes to Consolidated Financial Statements

                           December 31, 1992 and 1991



(1)  Summary of Significant Accounting Policies

     The accounting policies of American Republic Bancshares, Inc. (Bancshares)
       and subsidiaries (collectively referred to as the Company) conform to
       generally accepted accounting principles and to general practice within
       the banking industry. The following is a summary of the more significant
       of those policies:

     (a)  Basis of Presentation

          The consolidated financial statements include Bancshares and its
            wholly owned subsidiary, First National Bank of Belen (Bank).  The
            consolidated financial statements also include Bancshares' wholly
            owned subsidiary, Scientific Management Systems, Inc. (SMS), for the
            year ended December 31, 1991. During 1992, Bancshares dissolved SMS
            and combined its operations with Bancshares. SMS was not material to
            the operation of Bancshares.

          All significant intercompany balances and transactions have been
            eliminated in consolidation.

     (b)  Investment Securities

          Investment securities are stated at cost, adjusted for amortization of
            premiums and accretion of discounts.  The lower of cost or market is
            not used for securities valuation since the Bank has the ability and
            intent to hold the securities to maturity, except that costs of
            individual securities are written down to market when the ultimate
            realization of the recorded amounts are not reasonably assured.
            Gains or losses on the sale of investment securities are recognized
            using the identified certificate method.

     (c)  Allowance for Loan Losses

          Loan losses are charged to the allowance for loan losses and
            recoveries are credited to it. The provision for loan losses charged
            to expense is based on past loan loss experience, management's
            evaluation of the loan portfolio and other factors which, in
            management's judgment, deserve current recognition in estimating
            possible loan losses. Such other factors considered by management
            include growth and composition of the loan portfolio, the
            relationship of the allowance for loan losses to outstanding loans,
            collateral values and economic conditions. Material estimates that
            are particularly susceptible to significant change in the near term
            relate to the determination of the allowance for loan losses and the
            valuation of real estate in connection with the satisfaction of
            loans. Management obtains independent appraisals for significant
            properties that secure loans.

                                                                     (Continued)

                       AMERICAN REPUBLIC BANCSHARES, INC.
                                AND SUBSIDIARIES

                   Notes to Consolidated Financial Statements



          A substantial portion of the Bank's loans are secured by real estate
            in weak markets, primarily in New Mexico.  Accordingly, the ultimate
            collectibility of a substantial portion of the Bank's loan portfolio
            is susceptible to changes in real estate market conditions in New
            Mexico.

          Management believes that the allowance for losses on loans is
            adequate.  While management uses available information to recognize
            losses on loans, future additions to the allowance may be necessary
            based on changes in economic conditions. In addition, various
            regulatory agencies, as an integral part of their examination
            process, periodically review the Bank's allowance for losses on
            loans. Such agencies may require the Bank to recognize additions to
            the allowance based on their judgments about information available
            to them at the time of their examination.

     (d)  Income on Loans

          Interest is accrued on loans unless, in the opinion of management,
            collectibility of the interest is not probable.  When accrual of
            interest is discontinued, any previously accrued uncollected
            interest is charged against interest income. Interest on nonaccrual
            loans is recognized on a cash basis.

          Unearned interest on installment loans is amortized into income in
            amounts that approximate the interest method.

          Loan origination fees and direct costs of originating loans are
            amortized into income over the lives of the loans using a method
            that approximates the interest method.

     (e)  Premises and Equipment

          Premises and equipment are stated at cost less accumulated
            depreciation.  Depreciation is computed using the straight-line and
            declining-balance methods over the estimated useful lives of the
            assets.

          Maintenance and repairs are charged to expense in the year incurred.
            Renewals and material betterments are capitalized. Gains or losses
            on dispositions are credited or charged to income.

     (f)  Other Real Estate

          Other real estate is comprised of foreclosed properties where the Bank
            has actually received title or which are "in-substance"
            foreclosures. Loans are classified as in-substance foreclosures when
            the debtor has: (a) formally or informally abandoned control of the
            collateral to the Bank, or (b) retained control of the collateral
            but the economic prospects for the debtor and/or the

                                                                     (Continued)

                   Notes to Consolidated Financial Statements



            collateral make it doubtful that the debtor will be able to rebuild
            equity. Such properties are carried at the lower of the investment
            in the related loan or estimated net realizable value. Fair value of
            such assets is determined based on independent appraisals and other
            relevant factors.

          Declines in value, subsequent to acquisition, are accounted for as a
            charge to losses on other real estate and are included in other
            expenses in the period in which a decline in value is determined.
            Operating expenses, including rental or lease income and
            depreciation, and gains or losses from sales of other real estate
            are charged or credited to other operating expenses or income as
            incurred.

          A substantial portion of the other real estate is located in the same
            weak markets as discussed in note 1(c). Accordingly, the ultimate
            recovery of the Bank's carrying amount of other real estate is
            susceptible to changes in the real estate market conditions in New
            Mexico. In addition, such carrying values are periodically reviewed
            by the various regulatory agencies. Such agencies may require the
            Bank to recognize losses on other real estate based on their
            judgments about information available to them at the time of their
            examination.

     (g)  Excess of Cost Over Net Assets of Subsidiaries

          The excess of cost over net assets of the subsidiaries is amortized
            using the straight-line method over 20 years.

     (h)  Income Taxes

          The Company uses the asset and liability method of accounting for
            income taxes.

          Bancshares files consolidated federal and state income tax returns
            with its subsidiaries.

     (i)  Statement of Cash Flows

          For purposes of reporting cash flows, cash and cash equivalents
            include cash and due from banks and federal funds sold.

     (j)  Reclassifications

          Certain 1991 amounts have been reclassified to conform with the 1992
            financial statement presentation.

(2)  Restricted Cash Balance

     Included in cash and due from banks are balances which are maintained to
       meet reserve requirements established by the Federal Reserve Board.  At
       December 31, 1992, the required balance was $2,313,000.

                                                                     (Continued)

       an unrelated bank (bank) that matures on May 1, 1993 for the purpose of
       purchasing federal funds.  Any advances under this line are to be secured
       by a pledge of specific investment securities, and bears interest at the
       bank's quoted rate on the date of any advance.  At December 31, 1992, 
       there were no amounts outstanding under this line of credit.

     The Company currently accounts for income taxes under Statement of
       Financial Accounting Standards (SFAS) No. 96, "Accounting for Income
       Taxes." This statement has been superseded by Statement No. 109 which
       will be effective for fiscal years beginning after December 15, 1992,
       although earlier adoption is permitted. Statement No. 109, as was the
       case under Statement No. 96, will continue to retain the liability method
       of accounting for deferred income taxes. The Company anticipates
       implementing Statement No. 109 in the first quarter of 1993 on a
       prospective basis, but presently does not know and cannot reasonably
       estimate the impact of this Statement on its consolidated financial
       statements.

(10) Employee Benefit Plans

     The Company has a defined benefit pension plan covering substantially all
       of its employees. Prior to 1989, the benefits were based on years of
       service and the employee's highest consecutive 5-years compensation
       during the last 10 years of service. The Plan was amended, effective
       January 1, 1989, to provide a monthly retirement benefit of .75 percent
       of a participant's career average compensation multiplied by the years of
       service with a minimum monthly benefit of $5.00 multiplied by the years
       of service up to 40 years. Vesting occurs on a graduating basis, with
       full vesting achieved at the end of 7 years. The Company's funding policy
       is to annually contribute amounts necessary to maintain substantially
       full funding. The Company contributed $46,701 and $41,091 during the
       years ending December 31, 1992 and 1991, respectively, to this plan.

     At December 31, 1992, the fair value of the Plan's assets of $318,882
       (consisting primarily of cash and cash equivalents, U.S. government
       securities and mutual funds) exceeded the Plan's accumulated benefit
       obligation of $185,356.  The weighted average discount rate used in
       projecting the accumulated benefit obligation was 8.0 percent and the
       expected long-term rate of return on assets and rate of increase in
       future compensation levels were 9.0 percent and 5.0 percent,
       respectively. Net periodic pension costs incurred were $4,890 and $8,071
       in 1992 and 1991, respectively.

                                                                     (Continued)

     The Company also has a 401(k) savings plan under which the Company may
       match a portion of the employee's contribution up to 100 percent based on
       return on average assets, and a profit-sharing plan under which the
       Company may make contributions of up to 15 percent of the employee's
       compensation. Participation is available to substantially all employees.
       Vesting occurs on a graduating basis, with full vesting achieved at the
       end of 7 years. The Company may terminate either plan at any time. The
       Company contributed $24,147 to this plan in 1992. No contributions were
       made to this plan in 1991.

     The Company also has an Employee Stock Ownership Plan (ESOP) for
       substantially all of its employees. Total shares allocated to
       participants is based upon the employer's annual contribution. Such
       shares are allocated to individual participants based on the ratio of
       each participant's compensation to total participants' compensation.
       Vesting occurs on a graduating basis with full vesting achieved at the
       end of 7 years. The ESOP obtained a loan from an unrelated bank (note 8)
       that was used to purchase 13,513 outstanding shares of common stock from
       a stockholder. Contributions made by the Company to the ESOP are intended
       to pay principal and interest on the ESOP debt and, in turn, allocate a
       proportionate amount of the ESOP common stock shares to the participating
       employees. Any dividends on unallocated shares are also used to pay
       principal, interest and plan expenses. The ESOP debt is guaranteed by
       Bancshares and, therefore, is presented as long-term debt and a reduction
       of stockholders' equity. The Company contributed $63,160 and $54,872 to
       the ESOP of which $20,981 and $30,805 was attributable to interest on the
       ESOP debt for the years ending December 31, 1992 and 1991, respectively.

     The Company also has a supplemental benefit plan designed to provide
       certain employees with supplemental retirement benefits. The plan is
       being funded over a 5-year period with annual contributions of
       approximately $460,000. Benefits accrue to the employees over their
       employment and will provide the employees with salary continuation
       benefits upon retirement or death. As part of the plan, the Company has
       obtained insurance contracts on the plan participants in amounts
       sufficient to discharge the Company's obligations under the plan. Other
       assets include $1,065,798 and $1,172,892 at December 31, 1992 and 1991,
       respectively, of cash surrender value for the insurance contracts
       purchased; and accrued liabilities include $40,666 and $35,199 relating
       to benefits for the years ending December 31, 1992 and 1991,
       respectively. The Company recorded an expense of $3,241 and $25,217 in
       1992 and 1991, respectively, for benefits accruing under this plan.

                                                                     (Continued)

                   Notes to Consolidated Financial Statements

(11) Dividend Restrictions

     Undivided profits of the Bank include $12,000,000 not available for
       dividends to its stockholder because of regulatory requirements.  See 
       note 15 for additional restrictions on dividend payments.

(12) Risk-based Capital and Leverage Ratios

     In January 1989, the Federal Reserve Board and the Office of the
       Comptroller of the Currency issued guidelines which establish a risk-
       adjusted ratio relating capital to various categories of recorded assets
       and off-balance sheet commitments adjusted for relative credit risk. The
       guidelines require a minimum total risk-based capital ratio of 7.25
       percent with an 8.0 percent requirement by year-end 1992. At December 31,
       1992, Bancshares' total risk-based capital ratio was 15.42 percent.

     In early 1990, the Federal Reserve Board proposed a new minimum leverage
       ratio representing the minimum capital to total assets standard for
       banking organizations. The minimum leverage ratio required for those
       banks with the highest regulatory rating is 3.00 percent. At December 31,
       1992, Bancshares' leverage ratio was 7.34 percent.

(13) Fair Value of Financial Instruments

     Statement of Financial Accounting Standards No. 107, "Disclosures about
       Fair Value of Financial Instruments" (FAS 107) requires that Bancshares
       disclose estimated fair values for its financial instruments.  Fair value
       estimates are made at a specific point in time, based on relevant market
       information and information about the financial instrument.  These
       estimates do not reflect any premium or discount that could result from
       offering for sale at one time Bancshares' entire holdings of a particular
       financial instrument.  Because no market exists for a significant portion
       of Bancshares' financial instruments, fair value estimates are based on
       judgments regarding future expected loss experience, current economic
       conditions, risk characteristics of various financial instruments and
       other factors. These estimates are subjective in nature and involve
       uncertainties and matters of significant judgment and therefore cannot be
       determined with precision. Changes in assumptions could significantly
       affect the estimates.

     Fair value estimates are based on existing on and off-balance sheet
       financial instruments without attempting to estimate the value of
       anticipated future business and the value of assets and liabilities that
       are not considered financial instruments. Significant assets and
       liabilities that are not considered financial assets or liabilities
       include premises and equipment and other real estate owned. In addition,
       the tax ramifications related to the realization of the unrealized gains
       and losses can have a significant effect on fair value estimates and have
       not been considered in estimates.

                                                                     (Continued)

                   Notes to Consolidated Financial Statements

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

     Cash, short-term investments and short-term borrowings:
     The fair value of the short-term instruments approximates the carrying
     amounts because they mature in 90 days or less.

     Investment Securities:

     The fair value of securities is based on quoted market prices or dealer
     quotes, if available.  If a quoted market price for a specific security is
     not available, fair value is estimated using quoted market prices for
     similar securities.

     Loans:

     The fair value of loans is estimated by discounting the anticipated cash
     flows using appropriate current discount rates to determine their present
     value.  The yield on the U.S. Treasury security having a term which most
     closely corresponds to the term of the loan is the risk free discount rate
     used.  The risk free rate is adjusted for the operating expense component
     and the estimated credit quality component, which is the annualized yield
     needed to cover the expected loan losses.  The credit quality component is
     based on an analysis of under performing loans and gross charge-off
     experience.

     Deposit Liabilities:

     The fair value of deposits with no stated maturity, such as demand
     deposits, savings accounts, NOW accounts and money market deposits is the
     amount payable on demand at the reporting date.  The fair value of fixed-
     maturity certificates of deposit is based on the discounted anticipated
     cash flows using the appropriate risk free discount rate adjusted for the
     estimated credit quality relating to the "market view" of the
     creditworthiness of the institution based on selected financial ratios and
     the operating expense component.

     Long-term Debt:

     The fair value of long-term debt approximates the carrying amount as the
     majority of the debt is tied to floating interest rates thereby repricing
     the debt at current market values on a continual basis.

                                                                    (Continued)

(14) Condensed Financial Information of Parent Company

     The assets of Bancshares consist primarily of an investment in its
     subsidiary bank and the Bank's operating facilities.  As discussed in notes
     11 and 15, dividends paid by the Bank are limited by bank regulatory
     agencies.  The principal source of Bancshares' revenue is dividends from
     the subsidiary bank, which are utilized for payments of debt service,
     operating costs and dividends to Bancshare stockholders.  Condensed
     financial information of Bancshares at December 31, 1992 and 1991 follows:

                   Notes to Consolidated Financial Statements


(15)  Regulatory Matters

     In June 1992, the Board of Directors of the Bank entered into a Memorandum
     of Understanding (Memorandum) with the Office of the Comptroller of the
     Currency (OCC) that required the Bank to take a number of actions to
     strengthen the Bank's financial condition, including a review of the
     allowance for loan loss and submission of a three-year capital plan. In
     addition, the Memorandum required the formulation and enhancement of
     certain departments along with the establishment and implementation of a
     number of administrative policies and procedures relating to, among other
     things, loan review, appraisals and the process of determining the
     allowance for possible loan losses. The Memorandum also required the Bank
     to maintain certain minimum capital levels and obtain the approval of the
     OCC prior to the declaration or payment of any dividends.

     Since the implementation of the Memorandum, the OCC conducted another on-
     site examination as of November 30, 1992.  The OCC has indicated in a draft
     examination report that the Bank's overall compliance with the Memorandum
     is not yet at a desirable level.  As a result, the Memorandum will remain
     in effect until terminated by the OCC.  Failure to obtain compliance with
     the Memorandum in a timely manner could result in additional administrative
     action by the OCC.

                     AGREEMENT AND PLAN OF REORGANIZATION,

                                      AND

                                   AGREEMENT
                                      AND
                             PLAN OF REORGANIZATION

     AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") entered into as of
the 6th day of June, 1994, by and between AMERICAN REPUBLIC BANCSHARES, INC.
("ARBI"), 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 ARBI (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 ARBI of the par value
of $1.00 per share ("ARBI 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 ARBI pursuant to the Merger Agreement, with ARBI as the
surviving corporation, in which merger each share of ARBI Common Stock
outstanding immediately prior to the Effective Time of the Merger (as defined in
subparagraph (d) 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 the ARBI 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 ARBI held to vote on this
         Agreement and the Merger Agreement (the "Norwest Measurement Price") is
         equal to or greater than $26.50, the Adjusted Norwest Shares shall be
         the number determined by dividing (x) $27,950,000 plus the proceeds
         (net of commissions and similar expenses) received from the sale of
         certain securities pursuant to paragraph 4(s) by (y) $26.50;

    (ii) If the Norwest Measurement Price is equal to or less than $24.50, the
         Adjusted Norwest Shares shall be the number determined by dividing (x)
         $27,950,000 plus the proceeds (net of commissions and similar expenses)
         received from the sale of certain securities pursuant to paragraph 4(s)
         by (y) $24.50;

                                      A-1

<PAGE>
 
    (iii)  If the Norwest Measurement Price is less than $26.50, but more than
           $24.50, the Adjusted Norwest Shares shall be the number determined by
           dividing (x) $27,950,000 plus the proceeds (net of commissions and
           similar expenses) received from the sale of certain securities 
           pursuant to paragraph 4(s) by (y) 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 or 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 shares of
Norwest Common Stock into which a share of ARBI 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 ARBI Common Stock shall be converted will equal the
number of shares of Norwest Common Stock which the holder of a share of ARBI
Common Stock would have received pursuant to such reclassification,
recapitalization, split-up, combination, exchange of shares or 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).

    (d)  Mechanics of Closing Merger.  Subject to the terms and conditions set
forth herein, the Merger Agreement shall be executed and it and the Articles of
Merger shall be filed with the Secretary of State of New Mexico five business
days following the satisfaction or waiver of all conditions precedent set forth
in Sections 6 and 7 of this Agreement or on such other date as may be agreed to
by the parties (the "Closing Date").  Each of the parties agrees to use its best
efforts to cause the Merger to be completed as soon as practicable after the
receipt of approval by the ARBI shareholders of this Agreement and the Merger
Agreement and receipt of final regulatory approval of the Merger and the
expiration of all required waiting periods.  The time that the filing referred
to in the first sentence of this paragraph is made is herein referred to as the
"Time of Filing".  The day on which such filing is made and accepted is herein
referred to as the "Effective Date of the Merger".  The Effective Time of the
Merger shall be 11:59 p.m. Belen, New Mexico time on the Effective Date of the
Merger.  At the Effective Time of the Merger on the Effective Date of the
Merger, the separate existence of Merger Co. shall cease and Merger Co. will be
merged with and into ARBI pursuant to the Merger Agreement.

                                      A-2

    The closing of the transactions contemplated by this Agreement and the
Merger Agreement (the "Closing") shall take place on the Closing Date at the
offices of Norwest, Norwest Center, Sixth and Marquette, Minneapolis, Minnesota.

    2.  REPRESENTATIONS AND WARRANTIES OF ARBI.  ARBI represents and warrants to
Norwest as follows:

    (a)  Organization and Authority.  ARBI 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 ARBI and the ARBI 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.  ARBI 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").  ARBI has furnished Norwest true and correct copies of its articles of
incorporation and bylaws, as amended.

    (b)  ARBI's Subsidiaries.  Schedule 2(b) sets forth a complete and correct
list of all of ARBI's subsidiaries as of the date hereof (individually an "ARBI
Subsidiary" and collectively the "ARBI 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 ARBI.  No equity security of any ARBI
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 ARBI 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. (S) 55 (1982), all
of such shares so owned by ARBI 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 ARBI
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), ARBI 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 ARBI consists of
1,000,000 shares of common stock, $1.00 par value, of which as of the close of
business on March 31, 1994, 410,095 shares were outstanding and no shares were
held in the treasury and 1,000,000 shares of Cumulative Preferred Stock, $1.00
par value, of which as of the close of business on March 31, 1994, no shares
were outstanding and no shares were held in the treasury.  The maximum number of
shares of ARBI Common Stock (assuming for this purpose that phantom shares and
other share-equivalents, other than the performance shares provided pursuant to
the American Republic Bancshares Corporation Performance Share Incentive Bonus
Plan for James H. Foley dated December 21, 1993, constitute ARBI 

                                      A-3

<PAGE>
 
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 410,095. All of the outstanding shares of capital
stock of ARBI have been duly and validly authorized and issued and are fully
paid and nonassessable. There are no outstanding subscriptions, contracts,
conversion privileges, options, warrants, calls or other rights obligating ARBI
or any ARBI Subsidiary to issue, sell or otherwise dispose of, or to purchase,
redeem or otherwise acquire, any shares of capital stock of ARBI or any ARBI
Subsidiary. Since March 31, 1994 no shares of ARBI capital stock have been
issued, purchased, redeemed or otherwise acquired, directly or indirectly, by
ARBI or any ARBI Subsidiary and, except as set forth in Schedule 2(c), no
dividends or other distributions have been declared, set aside, made or paid to
the shareholders of ARBI. The Stock Restriction Agreement among certain
stockholders of ARBI has been amended to provide that it does not apply to the
transactions contemplated herein or in the Merger Agreement and such amendment
is in full force and effect and a copy thereof has been provided to Norwest.

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

    Except as set forth on Schedule 2(d), neither the execution, delivery and
performance by ARBI of this Agreement or the Merger Agreement, nor the
consummation of the transactions contemplated hereby and thereby, nor compliance
by ARBI with any of the provisions hereof or thereof, will (i) violate, conflict
with, or result in a breach of any provision of, or constitute a default (or an
event which, with notice or lapse of time or both, would constitute a default)
under, or result in the termination of, or accelerate the performance required
by, or result in a right of termination or acceleration of, or result in the
creation of, any lien, security interest, charge or encumbrance upon any of the
properties or assets of ARBI or any ARBI 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 ARBI or any ARBI Subsidiary
is a party or by which it may be bound, or to which ARBI or any ARBI Subsidiary
or any of the properties or assets of ARBI or any ARBI 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 ARBI, violate any
judgment, ruling, order, writ, injunction, decree, statute, rule or regulation
applicable to ARBI or any ARBI 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, 

                                      A-4

<PAGE>
 
authorizations, approvals or exemptions required under the BHC 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 ARBI of the transactions
contemplated by this Agreement and the Merger Agreement.

    (e)  ARBI Financial Statements.  The consolidated balance sheets of ARBI and
ARBI's Subsidiaries as of December 31, 1993 and 1992 and related consolidated
statements of operations, changes in stockholders' equity and cash flows for the
two years ended December 31, 1993, together with the notes thereto, certified by
KPMG Peat Marwick, and the unaudited consolidated balance sheets of ARBI and
ARBI's Subsidiaries as of March 31, 1994 and the related unaudited consolidated
statements of operations, changes in stockholders' equity and cash flows for the
three months then ended (collectively, the "ARBI Financial Statements"), have
been prepared in accordance with generally accepted accounting principles
applied on a consistent basis and present fairly (subject, in the case of
financial statements for interim periods, to normal recurring adjustments) the
consolidated financial position of ARBI and ARBI's Subsidiaries at the dates and
the consolidated results of operations and cash flows of ARBI and ARBI's
Subsidiaries for the periods stated therein.

    (f)  Reports.  Since December 31, 1988, ARBI and each ARBI Subsidiary has
filed all reports, registrations and statements, together with any required
amendments thereto, that it was required to file with (i) the Securities and
Exchange Commission (the "SEC"), including, but not limited to, Forms 10-K,
Forms 10-Q and proxy statements, (ii) the Federal Reserve Board, (iii) the
Federal Deposit Insurance Corporation (the "FDIC"), (iv) the United States
Comptroller of the Currency (the "Comptroller") and (v) any applicable state
securities or banking authorities.  All such reports and statements filed with
any such regulatory body or authority are collectively referred to herein as the
"ARBI Reports".  As of their respective dates, the ARBI Reports complied in all
material respects with all the rules and regulations promulgated by the SEC, 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
ARBI Reports have been made available to Norwest by ARBI.

    (g)  Properties and Leases.  Except (i) as may be reflected in the ARBI
Financial Statements, (ii) for any lien for current taxes not yet delinquent and
(iii) as provided in the last sentence of this subparagraph (g), ARBI and each
ARBI 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 the consolidated balance sheet as of March 31,
1994, and all real and personal property acquired since such date, except such
real and personal property as has been disposed of in the ordinary course of
business.  All leases of real property and all other leases material to ARBI or
any ARBI Subsidiary pursuant to which ARBI or such ARBI Subsidiary, as lessee,
leases real or personal property, which leases are described on Schedule 2(g),
are valid and effective in accordance with their respective terms, and there is
not, under any such lease, any material existing default by ARBI or such ARBI
Subsidiary or any event which, with notice or lapse of time or both, would
constitute such a material default.  Substantially all ARBI's and 

                                      A-5

<PAGE>
 
each ARBI Subsidiary's buildings and equipment in regular use have been well
maintained and are in good and serviceable condition, reasonable wear and tear
excepted. ARBI owns 67,757 shares of common stock of First Security Corporation
(all of which are subject to a lien in favor of First National Bank of
Farmington pursuant to the terms of the loan due June 30, 1999 described in
footnote 8 of the December 31, 1993 ARBI Financial Statements) and 1,000 shares
of common stock of Wachovia Corporation.

    (h)  Taxes.  Each of ARBI and the ARBI Subsidiaries has filed all federal,
state, county, local and foreign tax returns, including information returns,
required to be filed by it (except for the tax returns due for the fiscal year
ended December 31, 1993, for which extensions have been properly filed).  Except
as disclosed in Schedule 2(h), each of ARBI and the ARBI Subsidiaries have 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 ARBI and the ARBI Subsidiaries for the fiscal year ended December 31,
1990, and for all fiscal years prior thereto, are for the purposes of routine
audit by the Internal Revenue Service closed because of the statute of
limitations, and no claims for additional taxes for such fiscal years are
pending.  Neither ARBI nor any ARBI Subsidiary is a party to any pending action
or proceeding, nor is any such action or proceeding threatened by any
governmental authority, for the assessment or collection of taxes, interest,
penalties, assessments or deficiencies and no issue has been raised by any
federal, state, local or foreign taxing authority in connection with an audit or
examination of the tax returns, business or properties of ARBI or any ARBI
Subsidiary which has not been settled, resolved and fully satisfied.  Each of
ARBI and the ARBI 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 March 31, 1994, 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 ARBI and the ARBI Subsidiaries with respect to all periods
through the date thereof.

    (i)  Absence of Certain Changes.  Since March 31, 1994 there has been no
change in the business, financial condition or results of operations of ARBI or
any ARBI 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 ARBI and the ARBI Subsidiaries taken as a whole (other than
changes in banking laws or regulations, or interpretations thereof, that affect
the banking industry generally or changes in the general level of interest
rates).

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

          (i)  any employment contract or understanding (including any
     understandings or obligations with respect to severance or termination pay
     liabilities or fringe benefits) with any present or former officer,
     director, employee or consultant (other than those which are terminable at
     will by ARBI or such ARBI Subsidiary);

                                      A-6

<PAGE>
 
          (ii)  any plan, contract or understanding providing for any bonus,
     pension, option, deferred compensation, retirement payment, profit sharing
     or similar arrangement with respect to any present or former officer,
     director, employee or consultant;

          (iii)  any labor contract or agreement with any labor union;

          (iv)  any contract not made in the ordinary course of business
     containing covenants which limit the ability of ARBI or any ARBI Subsidiary
     to compete in any line of business or with any person or which involve any
     restriction of the geographical area in which, or method by which, ARBI or
     any ARBI Subsidiary may carry on its business (other than as may be
     required by law or applicable regulatory authorities);

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

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

          (vii)  any other contract or agreement that has a term of one year or
     more and annual payments of $50,000 or more.

  (k)  Litigation and Other Proceedings.  ARBI has furnished Norwest copies of
(i) all attorney responses to the request of the independent auditors for ARBI
with respect to loss contingencies as of December 31, 1993 in connection with
the ARBI Financial Statements for 1993, and (ii) neither ARBI nor any ARBI
Subsidiary has been served in connection with any legal or regulatory
proceedings since said date nor, to the best of ARBI's knowledge, have any legal
or regulatory proceedings been filed against ARBI or any ARBI Subsidiary since
said date.  Neither ARBI nor any ARBI Subsidiary is a party to any pending or,
to the best knowledge of ARBI, 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 ARBI and the ARBI Subsidiaries taken as a whole.

  (l)  Insurance.  ARBI and each ARBI Subsidiary is presently insured, and
during each of the past five calendar years (or during such lesser period of
time as ARBI has owned such ARBI Subsidiary) has been insured, for reasonable
amounts with insurance companies that, to the best knowledge of ARBI, 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.  For the three year period ending on the date hereof, ARBI has
provided Norwest with a true and complete list of, and, to the extent requested
by Norwest, copies of all documentation relating to, all (i) claims made and
denied, (ii) claims made and pending and (iii) circumstances forming the basis
for any future possible claims.

  (m)  Compliance with Laws.  ARBI and each ARBI Subsidiary has all permits,
licenses, authorizations, orders and approvals of, and has made all filings,
applications and 

                                      A-7

<PAGE>
 
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 ARBI or such ARBI Subsidiary; all such permits,
licenses, certificates of authority, orders and approvals are in full force and
effect and, to the best knowledge of ARBI, no suspension or cancellation of any
of them is threatened; and all such filings, applications and registrations are
current. The conduct by ARBI and each ARBI 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 other than laws,
statutes, ordinances, licenses or regulations relating to environmental
liability as to which ARBI makes only the representations and warranties set
forth in paragraph 2(v). Neither ARBI nor any ARBI 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 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 ARBI or any ARBI Subsidiary which reasonably could be
expected to have a material adverse effect on the business or properties of ARBI
and the ARBI Subsidiaries taken as a whole.

  (n)  Labor.  No work stoppage involving ARBI or any ARBI Subsidiary is pending
or, to the best knowledge of ARBI, threatened.  Neither ARBI nor any ARBI
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 ARBI or such ARBI Subsidiary taken as a whole.
Employees of ARBI and the ARBI Subsidiaries are not represented by any labor
union nor are any collective bargaining agreements otherwise in effect with
respect to such employees.  First National Bank of Belen (the "Bank") is in
compliance in all material respects with the terms of the Conciliation Agreement
between the U. S. Department of Labor, Office of Federal Contract Compliance
Programs, and the Bank dated December 28, 1992.

  (o)  Material Interests of Certain Persons.  Except as set forth on Schedule
2(o), to the best knowledge of ARBI no officer or director of ARBI or any ARBI
Subsidiary, or any "associate" (as such term is defined in Rule 14a-1 under the
Exchange Act) of any such officer or director, has any interest in any material
contract or property (real or personal), tangible or intangible, used in or
pertaining to the business of ARBI or any ARBI Subsidiary.

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

 (p)  ARBI 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 ARBI or any ARBI Subsidiary acts as the plan sponsor
     as defined in 

                                      A-8
<PAGE>
 
     ERISA Section 3(16)(B), and with respect to which any liability under ERISA
     or otherwise exists or may be incurred by ARBI or any ARBI Subsidiary are
     those set forth on Schedule 2(p) (the "Plans"). No Plan is a "multi-
     employer plan" within the meaning of Section 3(37) of ERISA.

          (ii)  Each Plan is and has been in all material respects operated and
     administered in accordance with its provisions and applicable law.  Except
     as set forth on Schedule 2(p), ARBI or the ARBI subsidiaries have received
     favorable determination letters from the Internal Revenue Service under the
     provisions of the Tax Equity and Fiscal Responsibility Act ("TEFRA"), the
     Deficit Reduction Act ("DEFRA") and the Retirement Equity Act ("REA") for
     each of the Plans to which the qualification requirements of Section 401(a)
     of the Internal Revenue Code of 1986, as amended (the "Code"), apply.  ARBI
     knows of no reason that any Plan which is subject to the qualification
     provisions of Section 401(a) of the Code is not "qualified" within the
     meaning of Section 401(a) of the Code and that each related trust is not
     exempt from taxation under Section 501(a) of the Code, except that any such
     Plan may not have been amended to comply with the Tax Reform Act of 1986
     (the "TRA") and other recent legislation and regulations, although each
     such Plan is within the remedial amendment period during which retroactive
     amendment may be made.

          (iii)  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 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)  To the best knowledge of ARBI, no Plan or any trust created
     thereunder, nor any trustee, fiduciary or administrator thereof, has
     engaged in a "prohibited transaction", as such term is defined in Section
     4975 of the Code or Section 406 of ERISA or violated any of the fiduciary
     standards under Part 4 of Title I of ERISA which could subject, to the best
     knowledge of ARBI, 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 ARBI and the ARBI Subsidiaries
     taken as a whole.

          (v)  No 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 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), since the effective date of ERISA.

          (vii)  Except as disclosed in Schedule 2(p), neither the execution and
     delivery of this Agreement and the Merger Agreement nor the consummation of
     the

                                      A-9

<PAGE>
 
     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 ARBI or any ARBI 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 ARBI and the
ARBI Subsidiaries supplied or to be supplied by ARBI 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 ARBI Common Stock pursuant to the provisions of the Merger Agreement
(the "Registration Statement"), (ii) the proxy statement to be mailed to ARBI'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 which
ARBI and the ARBI Subsidiaries are responsible for filing with the SEC and 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
ARBI nor any ARBI Subsidiary is under any obligation, contingent or otherwise,
which will survive the Merger by reason of any agreement to register any of its
securities under the Securities Act.

  (s)  Brokers and Finders.  Except as set forth on Schedule 2(s), neither ARBI
nor any ARBI 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 ARBI or any ARBI
Subsidiary in connection with this Agreement and the Merger Agreement or the
transactions contemplated hereby and thereby.

  (t)  Administration of Trust Accounts.  ARBI and each ARBI Subsidiary has
properly administered in all respects material and which could reasonably be
expected to be material to the financial condition of ARBI and the ARBI
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 ARBI, any ARBI Subsidiary,
nor any director, officer or employee of ARBI or any ARBI Subsidiary has
committed any breach of trust with respect to any such fiduciary account which
is material 

                                      A-10

<PAGE>
 
to or could reasonably be expected to be material to the financial condition of
ARBI and the ARBI 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 ARBI nor any ARBI 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 ARBI and the ARBI Subsidiaries, taken as a whole.  To the best of ARBI's
knowledge, all parties with whom ARBI or any ARBI Subsidiary has material
leases, agreements or contracts or who owe to ARBI or any ARBI Subsidiary
material obligations other than with respect to those arising in the ordinary
course of the banking business of the ARBI Subsidiaries are in compliance
therewith in all material respects.

  (v)  Environmental Liability.  There is no legal, administrative, or other
proceeding, claim, or action of any nature seeking to impose, or that could
reasonably be expected to result in the imposition of, on ARBI or any ARBI
Subsidiary, 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, pending or to the
best of ARBI's knowledge, threatened against ARBI or any ARBI Subsidiary the
result of which has had or could reasonably be expected to have a material
adverse effect upon ARBI and ARBI's Subsidiaries taken as a whole; to the best
of ARBI's knowledge there is no reasonable basis for any such proceeding, claim
or action; and to the best of ARBI's knowledge neither ARBI nor any ARBI
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.  ARBI has provided Norwest with copies of all environmental
assessments, reports, studies and other related information in their possession
with respect to each bank facility, each non-residential OREO property and the
property owned by El Pueblo Properties.

  (w)  From March 31, 1994 through the date hereof, the "Provision for Loan
Losses" in the ARBI financial statements has not at any time been less than
zero.

  3.  REPRESENTATIONS AND WARRANTIES OF NORWEST.  Norwest represents and
warrants to ARBI as follows:

  (a)  Organization and Authority.  Norwest is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware,
is duly qualified to do business and is in good standing in all jurisdictions
where its ownership or leasing of property or the conduct of its business
requires it to be so qualified and failure to be so qualified would have a
material adverse effect on Norwest and its subsidiaries taken as a whole and has
corporate power and authority to own its properties and assets and to carry on
its business as it is now being conducted.  Norwest is registered as a bank
holding company with the Federal Reserve Board under the BHC Act.

                                      A-11

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

  (c)  Norwest Capitalization.  The authorized capital stock of Norwest consists
of (i) 5,000,000 shares of Preferred Stock, without par value, of which as of
the close of business on April 30, 1994,1,135,000 shares of 10.24% Cumulative
Preferred Stock at $100 stated value, 1,143,750 shares of Cumulative Convertible
Preferred Stock, Series B, at $200 stated value and 35,125 shares of ESOP
Cumulative Convertible Preferred Stock at $1,000 stated value were outstanding,
and (ii) 500,000,000 shares of Common Stock, $1-2/3 par value, of which as of
the close of business on April 30, 1994, 318,480,722 shares were outstanding and
4,296,052 shares were held in the treasury.  On November 22, 1988, the Board of
Directors of Norwest declared a dividend of one preferred share purchase right
(collectively, the "Rights") for each outstanding share of Norwest Common Stock.
The dividend was paid on December 9, 1988, to stockholders of record on that
date.  Holders of shares of Norwest Common Stock issued subsequent to that date,
including those to be issued in connection with the Merger, will receive the
Rights with their shares.  The Rights trade automatically with shares of Norwest
Common Stock and become exercisable only under certain circumstances.

  (d)  Authorization.  Norwest has the corporate power and authority to enter
into this Agreement and to carry out its obligations hereunder.  The execution,
delivery and performance of this Agreement by Norwest and the consummation of
the transactions contemplated hereby have been duly authorized by the Board of
Directors of Norwest.  No approval or consent by the stockholders of Norwest is
necessary for the execution and delivery of this Agreement and the Merger
Agreement and the consummation of the transactions contemplated hereby and
thereby.  Subject to such approvals of government agencies and other governing
boards having regulatory authority over Norwest as may be required by statute or
regulation, this Agreement is a valid and binding obligation of Norwest
enforceable against Norwest in accordance with its terms.

  Neither the execution, delivery and performance by Norwest of this Agreement
or the Merger Agreement, nor the consummation of the transactions contemplated
hereby and thereby, nor compliance by Norwest with any of the provisions hereof
or thereof, will (i) 

                                      A-12

<PAGE>
 
violate, conflict with, or result in a breach of any provision of, or constitute
a default (or an event which, with notice or lapse of time or both, would
constitute a default) under, or result in the termination of, or accelerate the
performance required by, or result in a right of termination or acceleration of,
or result in the creation of, any lien, security interest, charge or encumbrance
upon any of the properties or assets of Norwest or any Norwest Subsidiary under
any of the terms, conditions or provisions of (x) its certificate of
incorporation or by-laws or (y) any material note, bond, mortgage, indenture,
deed of trust, license, lease, agreement or other instrument or obligation to
which Norwest or any Norwest Subsidiary is a party or by which it may be bound,
or to which Norwest or any Norwest Subsidiary or any of the properties or assets
of Norwest or any Norwest Subsidiary may be subject, or (ii) subject to
compliance with the statutes and regulations referred to in the next paragraph,
to the best knowledge of Norwest, violate any judgment, ruling, order, writ,
injunction, decree, statute, rule or regulation applicable to Norwest or any
Norwest Subsidiary or any of their respective properties or assets.

  Other than in connection with or in compliance with the provisions of the
Securities Act, the Exchange Act, the securities or blue sky laws of the various
states or filings, consents, reviews, authorizations, approvals or exemptions
required under the BHC Act, 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 Norwest of the transactions contemplated by this Agreement and
the Merger Agreement.

  (e)  Norwest Financial Statements.  The consolidated balance sheets of Norwest
and Norwest's subsidiaries as of December 31, 1993 and 1992 and related
consolidated statements of income, stockholders' equity and cash flows for the
three years ended December 31, 1993, together with the notes thereto, certified
by KPMG Peat Marwick and included in Norwest's Annual Report on Form 10-K for
the fiscal year ended December 31, 1993 as amended by Form 10-K/A dated May 13,
1994 (the "Norwest 10-K") as filed with the SEC, and the unaudited consolidated
balance sheets of Norwest and its subsidiaries as of March 31, 1994 and the
related unaudited consolidated statements of income and cash flows for the three
months then ended included in Norwest's Quarterly Report on Form 10-Q for the
fiscal quarter ended March 31, 1994, as filed with the SEC (collectively, the
"Norwest Financial Statements"), have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis and present fairly
(subject, in the case of financial statements for interim periods, to normal
recurring adjustments) the consolidated financial position of Norwest and its
subsidiaries at the dates and the consolidated results of operations, changes in
financial position and cash flows of Norwest and its subsidiaries for the
periods stated therein.

  (f)  Reports.  Since December 31, 1988, Norwest and each Norwest Subsidiary
has filed all reports, registrations and statements, together with any required
amendments thereto, that it was required to file with (i) the SEC, including,
but not limited to, Forms 10-K, Forms 10-Q and proxy statements, (ii) the
Federal Reserve Board, (iii) the FDIC, (iv) the Comptroller and (v) any
applicable state securities or banking authorities.  All such reports and
statements filed with any such regulatory body or authority are collectively
referred to herein as the "Norwest Reports".  As of their respective dates, the
Norwest Reports complied in all material respects with all the rules and
regulations promulgated by the SEC, the Federal Reserve Board, the FDIC, the
Comptroller and any applicable state 

                                      A-13

<PAGE>
 
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. Norwest has
provided ARBI with copies of its Form 10-K for the year ended December 31, 1993
as amended by Amendment No. 1 on Form 10-K/A dated May 13, 1994, its Form 10-Q
for the quarter ended March 31, 1994, its Form 8-K dated February 15, 1994 and
its Proxy Statement dated March 23, 1994.

  (g)  Properties and Leases.  Except as may be reflected in the Norwest
Financial Statements and except for any lien for current taxes not yet
delinquent, Norwest and each Norwest Subsidiary has good title free and clear of
any material liens, claims, charges, options, encumbrances or similar
restrictions to all the real and personal property reflected in Norwest's
consolidated balance sheet as of March 31, 1994 included in Norwest's Quarterly
Report on Form 10-Q for the period then ended, and all real and personal
property acquired since such date, except such real and personal property has
been disposed of in the ordinary course of business.  All leases of real
property and all other leases material to Norwest or any Norwest Subsidiary
pursuant to which Norwest or such Norwest Subsidiary, as lessee, leases real or
personal property, are valid and effective in accordance with their respective
terms, and there is not, under any such lease, any material existing default by
Norwest or such Norwest Subsidiary or any event which, with notice or lapse of
time or both, would constitute such a material default.  Substantially all
Norwest's and each Norwest Subsidiary's buildings and equipment in regular use
have been well maintained and are in good and serviceable condition, reasonable
wear and tear excepted.

  (h)  Taxes.  Each of Norwest and the Norwest Subsidiaries has filed all
material federal, state, county, local and foreign tax returns, including
information returns, required to be filed by it, and paid or made adequate
provision for the payment of all taxes owed by it, including those with respect
to income, withholding, social security, unemployment, workers compensation,
franchise, ad valorem, premium, excise and sales taxes, and no taxes shown on
such returns to be owed by it or assessments received by it are delinquent.  The
federal income tax returns of Norwest and the Norwest Subsidiaries for the
fiscal year ended December 31, 1979, and for all fiscal years prior thereto, are
for the purposes of routine audit by the Internal Revenue Service closed because
of the statute of limitations, and no claims for additional taxes for such
fiscal years are pending.  Except only as set forth on Schedule 3(h), (i)
neither Norwest nor any Norwest Subsidiary is a party to any pending action or
proceeding, nor to Norwest's knowledge is any such action or proceeding
threatened by any governmental authority, for the assessment or collection of
taxes, interest, penalties, assessments or deficiencies which could reasonably
be expected to have any material adverse effect on Norwest and its subsidiaries
taken as a whole, and (ii) no issue has been raised by any federal, state, local
or foreign taxing authority in connection with an audit or examination of the
tax returns, business or properties of Norwest or any Norwest Subsidiary which
has not been settled, resolved and fully satisfied, or adequately reserved for.
Each of Norwest and the Norwest Subsidiaries has paid all taxes owed or which it
is required to withhold from amounts owing to employees, creditors or other
third parties.

  (i)  Absence of Certain Changes.  Since March 31, 1994, 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 

                                      A-14

<PAGE>
 
on the business, financial condition or results of operations of Norwest and its
subsidiaries taken as a whole (other than changes in banking laws or
regulations, or interpretations thereof, that affect the banking industry
generally or changes in the general level of interest rates).

  (j)  Commitments and Contracts.  Except as set forth on Schedule 3(j), as of
April 1, 1994, neither Norwest nor any Norwest Subsidiary is a party or subject
to any of the following (whether written or oral, express or implied):

          (i)  any labor contract or agreement with any labor union;

          (ii)  any contract not made in the ordinary course of business
     containing covenants which materially limit the ability of Norwest or any
     Norwest Subsidiary to compete in any line of business or with any person or
     which involve any material restriction of the geographical area in which,
     or method by which, Norwest or any Norwest Subsidiary may carry on its
     business (other than as may be required by law or applicable regulatory
     authorities);

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

  (k)  Litigation and Other Proceedings.  Neither Norwest nor any Norwest
Subsidiary is a party to any pending or, to the best knowledge of Norwest,
threatened, claim, action, suit, investigation or proceeding, or is subject to
any order, judgment or decree, except for matters which, in the aggregate, will
not have, or cannot reasonably be expected to have, a material adverse effect on
the business, financial condition or results of operations of Norwest and its
subsidiaries taken as a whole.

  (l)  Insurance.  Norwest and each Norwest Subsidiary is presently insured 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 insurance companies that,
to the best knowledge of Norwest, 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.

  (m)  Compliance with Laws.  Norwest and each Norwest Subsidiary has all
permits, licenses, authorizations, orders and approvals of, and has made all
filings, applications and registrations with, federal, state, local or foreign
governmental or regulatory bodies that are required in order to permit it to own
or lease its properties or assets and to carry on its business as presently
conducted and that are material to the business of Norwest or such Subsidiary;
all such permits, licenses, certificates of authority, orders and approvals are
in full force and effect, and to the best knowledge of Norwest, no suspension or
cancellation of any of them is threatened; and all such filings, applications
and registrations are current.  The conduct by Norwest and each Norwest
Subsidiary of its business and the condition and use of its properties does not
violate or infringe, in any respect material to any such business, any
applicable domestic (federal, state or local) or foreign law, statute,
ordinance, license or regulation other than laws, statutes, ordinances, licenses
or regulations relating to environmental liability as to which Norwest makes
only 

                                      A-15

<PAGE>
 
the representations and warranties set forth in paragraph 3(s). Neither Norwest
nor any Norwest Subsidiary is in default under any order, license, regulation or
demand of any federal, state, municipal or other governmental agency or with
respect to any order, writ, injunction or decree of any court. Except for
statutory or regulatory restrictions of general application, no federal, state,
municipal or other governmental authority has placed any restrictions on the
business or properties of Norwest or any Norwest Subsidiary which reasonably
could be expected to have a material adverse effect on the business or
properties of Norwest and its subsidiaries taken as a whole.

  (n)  Labor.  No work stoppage involving Norwest or any Norwest Subsidiary is
pending or, to the best knowledge of Norwest, threatened.  Neither Norwest nor
any Norwest Subsidiary is involved in, or threatened with or affected by, any
labor dispute, arbitration, lawsuit or administrative proceeding which could
materially and adversely affect the business of Norwest or such Norwest
Subsidiary.  Except as set forth on Schedule 3(j), employees of Norwest and the
Norwest Subsidiaries are not represented by any labor union nor are any
collective bargaining agreements otherwise in effect with respect to such
employees.

 (o)  Norwest Benefit Plans.

          (i)  As of April 1, 1994, the only "employee benefit plans" within the
     meaning of Section 3(3) of ERISA for which Norwest or any Norwest
     Subsidiary acts as plan sponsor as defined in ERISA Section 3(16)(B) with
     respect to which any liability under ERISA or otherwise exists or may be
     incurred by Norwest or any Norwest Subsidiary are those set forth on
     Schedule 3(o) (the "Norwest Plans").  No Norwest Plan is a "multi-employer
     plan" within the meaning of Section 3(37) of ERISA.

          (ii)  Each Norwest Plan is and has been in all material respects
     operated and administered in accordance with its provisions and applicable
     law.  Except as set forth on Schedule 3(o), Norwest or the Norwest
     Subsidiaries have received favorable determination letters from the
     Internal Revenue Service under the provisions of the Tax Equity and Fiscal
     Responsibility Act ("TEFRA"), the Deficit Reduction Act ("DEFRA") and the
     Retirement Equity Act ("REA") for each of the Norwest Plans to which the
     qualification requirements of Section 401(a) of the Code apply.  Norwest
     knows of no reason that any Norwest Plan which is subject to the
     qualification provisions of Section 401(a) of the Code is not "qualified"
     within the meaning of Section 401(a) of the Code and that each related
     trust is not exempt from taxation under Section 501(a) of the Code, except
     that any such Norwest Plan may not have been amended to comply with TRA and
     other recent legislation and regulations, although each such Norwest Plan
     is within the remedial amendment period during which retroactive amendment
     may be made.

          (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.

                                      A-16
<PAGE>
 
          (iv)  Except as set forth on Schedule 3(o), and to the best knowledge
     of Norwest, no Norwest Plan or any trust created thereunder, nor any
     trustee, fiduciary or administrator thereof, has engaged in a "prohibited
     transaction", as such term is defined in Section 4975 of the Code or
     Section 406 of ERISA or violated 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), 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 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 which Norwest and the Norwest
Subsidiaries are responsible for filing with the SEC and 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 any
of their respective officers, directors or employees has employed any broker or
finder or 

                                      A-17

<PAGE>
 
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 Norwest or any Norwest Subsidiary in connection with this
Agreement and the Merger Agreement or the transactions contemplated hereby and
thereby.

  (r)  No Defaults.  Neither Norwest nor any Norwest 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 Norwest and its subsidiaries taken as a whole.  To the best
of Norwest's knowledge, all parties with whom Norwest or any Norwest Subsidiary
has material leases, agreements or contracts or who owe to Norwest or any
Norwest Subsidiary material obligations other than with respect to those arising
in the ordinary course of the banking business of the Norwest Subsidiaries are
in compliance therewith in all material respects.

  (s)  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 Norwest or any Norwest
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, pending or to the
best of Norwest's knowledge, threatened against Norwest or any Norwest
Subsidiary, the result of which has had or could reasonably be expected to have
a material adverse effect upon Norwest and its subsidiaries taken as a whole; to
the best of Norwest's knowledge there is no reasonable basis for any such
proceeding, claim or action; and to the best of Norwest's knowledge neither
Norwest nor any Norwest Subsidiary is subject to any agreement, order, judgment,
or decree by or with any court, governmental authority or third party imposing
any such environmental liability.

  (t)  Merger Co.  As of the Closing Date, Merger Co. will be a corporation duly
organized, validly existing, duly qualified to do business and in good standing
under the laws of New Mexico, and will have corporate power and authority to own
or lease its properties and assets and to carry on its business.

 4.  COVENANTS OF ARBI.  ARBI covenants and agrees with Norwest as follows:

  (a)  Except as permitted in writing by Norwest or as otherwise permitted or
required by this Agreement, from the date hereof until the Effective Time of the
Merger, ARBI, and each ARBI Subsidiary will:  maintain its corporate existence
in good standing; maintain the general character of its business and conduct its
business in its ordinary and usual manner; extend credit in accordance with
existing lending policies, except that it shall not, without the prior written
consent of Norwest, make any new loan or modify, restructure or renew any

with all other loans or extensions of credit to such person, would be in excess
of $200,000; maintain proper business and accounting records in accordance with
generally accepted principles; maintain its properties in good repair and
condition, ordinary wear and

Merger; comply in all material respects with all laws, regulations, ordinances,
codes, orders, licenses and permits applicable to the properties and operations
of ARBI and each ARBI Subsidiary the non-compliance with which reasonably could
be expected to have a material adverse effect on ARBI and the ARBI Subsidiaries
taken as a whole; and permit Norwest and its representatives (including KPMG
Peat Marwick) to examine its and its subsidiaries books, records and properties
and to interview officers, employees and agents at all reasonable times when it
is open for business. No such examination by Norwest or its representatives
either before or after the date of this Agreement shall in any way affect,
diminish or terminate any of the representations, warranties or covenants of
ARBI herein expressed.

  (b)  Except as otherwise contemplated or required by this Agreement, from the
date hereof until the Effective Time of the Merger, ARBI and each ARBI
subsidiary will not (without the prior written consent of Norwest):  amend or
otherwise change its articles of incorporation or association or by-laws; issue

agreements with respect to the issuance or sale or conversion of, any shares of
its capital stock, phantom shares or other share-equivalents, or any other of
its securities; authorize or incur any long-term debt (other than deposit
liabilities); mortgage, pledge or subject to lien or other encumbrance any of

final maturities of up to one year and in amounts of $100,000 or less; amend or
terminate any Plan except as required by law; make any contributions to any Plan

declare, set aside, make or pay any dividend or other distribution with respect

quarters of 1994 only of not more than $.25/share and, in the event that the
Effective Time of the Merger has not occurred on or before March 31, 1995, a
regular quarterly cash dividend on the ARBI Common Stock for the first quarter
of 1995 only of not more than $.25/share; redeem, purchase or otherwise acquire,
directly or indirectly, any of the capital stock of ARBI; increase the
compensation of any officers, directors or executive employees, except pursuant
to existing compensation plans and practices and except that ARBI or the Bank
may pay an aggregate of $150,000 in bonuses to persons who, on the day before
the Effective Date of the Merger, are employees of ARBI or the Bank ; sell or
otherwise dispose of any shares of the capital stock of any ARBI Subsidiary; or
sell or otherwise dispose of any of its assets or properties other than in the
ordinary course of business.

  (c)  The Board of Directors of ARBI will duly call, and will cause to be held
not later than twenty-three (23) business days following the effective date of
the Registration Statement referred to in paragraph 5(c) hereof, a meeting of
its shareholders and will direct 

                                      A-19

<PAGE>

concerning ARBI and its subsidiaries required for inclusion in the Registration
Statement referred to in paragraph 5(c) hereof, or any statement or application
made by Norwest to any governmental body in connection with the transactions
contemplated by this Agreement.  Any financial statement for any fiscal year
provided under this paragraph must include the audit opinion and the consent of
KPMG Peat Marwick to use such opinion in such Registration Statement.  Any
interim quarterly financial information provided under this paragraph must have
been reviewed by KPMG Peat Marwick in accordance with generally accepted
auditing standards and ARBI must provide Norwest with a copy of such review
report.

  (e)  ARBI will take all necessary corporate and other action and use its best
efforts to obtain all approvals of regulatory authorities, consents and other
approvals required of ARBI to carry out the transactions contemplated by this
Agreement and will cooperate with Norwest to obtain all such approvals and
consents required of Norwest.

  (f)  ARBI will use its best efforts to deliver at the Closing all opinions,

connection with the transactions contemplated by this Agreement and will not
release or disclose such information to any other person, except as required by
law and except to ARBI's outside professional advisers in connection with this
Agreement, with the same undertaking from such professional advisers.  In the
event that ARBI or its representatives receive a request pursuant to judicial or
regulatory process to disclose such confidential information, ARBI will, unless
prohibited by law, promptly notify Norwest of such request and will cooperate
with Norwest, at the Norwest's expense, to obtain a protective order or other
reliable assurance that confidential treatment will be accorded to such
confidential information.  If the transactions contemplated by this Agreement
shall not be consummated, such confidence shall be maintained and such
information shall not be used in competition with Norwest (except to the extent
that such information can be shown to be previously known to ARBI, in the public
domain, or later acquired by ARBI from other legitimate sources) and, upon
request, all such documents, any copies thereof and extracts therefrom shall
immediately thereafter be returned to Norwest.

  (h)  Neither ARBI, nor any ARBI Subsidiary, nor any director, officer,
representative or agent thereof, will, directly or indirectly, solicit,
authorize the solicitation of or enter into any discussions with any
corporation, partnership, person or other entity or group (other than Norwest)

stock, any option or warrant to purchase any shares of common stock, any
securities convertible into any shares of such common stock, or any other equity
security of ARBI or any ARBI Subsidiary, (ii) to make a tender or exchange offer
for any 

                                      A-20

<PAGE>
 
shares of such common stock or other equity security, (iii) to purchase, lease
or otherwise acquire the assets of ARBI or any ARBI Subsidiary except in the
ordinary course of business, or (iv) to merge, consolidate or otherwise combine
with ARBI or any ARBI Subsidiary. If any corporation, partnership, person or
other entity or group makes an offer or inquiry to ARBI or any ARBI Subsidiary
concerning any of the foregoing, ARBI or such ARBI Subsidiary will promptly
disclose such offer or inquiry, including the terms thereof, to Norwest.

  (i)  ARBI shall consult with Norwest as to the form and substance of any
proposed press release or other proposed public disclosure of matters related to
this Agreement or any of the transactions contemplated hereby.

  (j)  ARBI and each ARBI Subsidiary will take all action necessary or required
(i) to terminate or amend, if requested by Norwest, all qualified pension and
welfare benefit plans and all non-qualified benefit plans and compensation
arrangements as of the Effective Date of the Merger, (ii) to amend the Plans to
comply with the provisions of the TRA and regulations thereunder and other
applicable law, and (iii) to submit application to the Internal Revenue Service
for a favorable determination letter for each of the Plans which is subject to
the qualification requirements of Section 401(a) of the Code prior to the
Effective Date of the Merger, provided that ARBI and each ARBI Subsidiary will
not be required to submit such application to the Internal Revenue Service if
the Internal Revenue Service does not accept such applications prior to the
Effective Date of the Merger.

  (k)  ARBI shall use its best efforts to obtain and deliver at least 32 days
prior to the Effective Date of the Merger signed representations substantially
in the form attached hereto as Exhibit B to Norwest by each executive officer,
director or shareholder of ARBI who may reasonably be deemed an "affiliate" of
ARBI within the meaning of such term as used in Rule 145 under the Securities
Act.

  (l)  ARBI shall establish such additional accruals and reserves as may be
necessary to conform ARBI's accounting and credit loss reserve practices and
methods to those of Norwest and Norwest's plans with respect to the conduct of
ARBI's business following the Merger and to provide for the costs and expenses
relating to the consummation by ARBI of the Merger and the other transactions

ARBI's sole expense, Phase I environmental assessments for each bank facility,

  (o)  Immediately prior to the Effective Time of the Merger, ARBI shall apply
the funds to be loaned to it by Norwest pursuant to paragraph 5(n) hereof to pay
in full all indebtedness of ARBI secured by the stock of any ARBI Subsidiary.

  (p)  Prior to the Effective Date of the Merger, ARBI shall distribute or cause
to be distributed, at fair market value, to an irrevocable trust established for
the exclusive ratable benefit of all of the shareholders of record of ARBI as of
the date of distribution (i) all of the artwork owned by ARBI or any ARBI
Subsidiary listed on Schedule 4(p) and any indebtedness incurred in the purchase
of such artwork, including, but not limited to, the note payable to Brownell
McGrew for the purchase of two pieces of art, (ii) all equity securities of New
Mexico Financial Corporation owned by ARBI or any ARBI Subsidiary and (iii)
$50,000 in cash.  Such distribution shall be accomplished pursuant to an
agreement that provides that neither ARBI nor any ARBI Subsidiary shall have any
further rights or obligations with respect to the trust, the trustee, the
beneficiaries of the trust or the assets of the trust.  Such agreement shall
also provide that, except for liability for corporate taxes payable by ARBI or
any ARBI Subsidiary on the distribution at fair market value of the above-
described artwork and related debt and equity securities, ARBI and the ARBI
Subsidiaries shall have no liability with respect to the trust and no further
liability with respect to the assets or liabilities of the trust following such
distribution, including, but not limited to, liability for any property that
remains unclaimed by any shareholders.  Norwest shall have the right to approve
the terms and conditions of the creation of such trust  and of such distribution
which approval shall not be unreasonably withheld.

  (q)  From the date hereof through the Effective Date of the Merger, ARBI shall
not permit the "Provision for Loan Losses" in the ARBI financial statements to
be less than zero.

  (r)  As soon as practical, but in any event prior to the Effective Date of the
Merger, ARBI shall cause the Bank to sell its entire interest in El Pueblo
Properties.

  (s)  No later than five business days prior to the Effective Date of the
Merger, ARBI shall sell all of the equity securities it owns in First Security
Corporation and in Wachovia Corporation.

  (t)  At the request of Norwest, ARBI shall, prior to the Effective Time of the
Merger, prepay in full without penalty the indebtedness listed on Schedule 2(d),
terminate all related agreements and obtain the release of all collateral held
in connection therewith.

 5.  COVENANTS OF NORWEST.  Norwest covenants and agrees with ARBI as follows:

  (a)  From the date hereof until the Effective Time of the Merger, Norwest will

approvals of regulatory authorities, consents and approvals required of it to
carry out the transactions 

                                      A-23

contemplated by this Agreement and will cooperate with ARBI to obtain all such
approvals and consents required by ARBI.

  (h)  Norwest will hold in confidence all documents and information concerning
ARBI and ARBI's Subsidiaries furnished to it and its representatives in
connection with the transactions contemplated by this Agreement and will not
release or disclose such information to any other person, except as required by
law and except to its outside professional advisers in connection with this
Agreement, with the same undertaking from such professional advisers.  In the
event that Norwest or its representatives receive a request pursuant to judicial

unless prohibited by law, promptly notify ARBI of such request and will
cooperate with ARBI, at ARBI's expense, to obtain a protective order or other

public domain, or later acquired by Norwest from other legitimate sources) and,
upon request, all such documents, copies thereof or extracts therefrom shall

indemnification in ARBI's Articles of Incorporation and Bylaws and in the

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 the
provisions of such articles and bylaws prior to the Effective Time of the
Merger, survive the Merger and shall continue in full force and effect for three
years from the Effective Time of the Merger. Nothing contained in this paragraph
5(o) shall be deemed to preclude the liquidation, consolidation, merger or
amendment of the articles of incorporation or bylaws of ARBI or any ARBI
Subsidiary in which case all of such rights to indemnification shall be deemed
to survive and continue notwithstanding any such liquidation, consolidation,
merger or amendment. Notwithstanding anything to the contrary contained in this

person who was a director, officer or employee of a corporation, banking
institution or other entity acquired by ARBI or any ARBI Subsidiary with respect
to claims based on, or arising out of or pertaining to, a matter which occurred
prior to the consummation of any such acquisition to a greater extent than ARBI

indemnify any such person.

  (p)  At or prior to the Effective Time of the Merger, Norwest shall deposit,
or shall cause to be deposited, with Norwest Bank Minnesota, N.A. (the "Agent"),

Merger Agreement, a certificate or certificates representing the shares of
Norwest Common Stock and the cash in lieu of fractional shares to be issued and
paid pursuant hereto and the Merger Agreement in exchange for outstanding shares
of ARBI Common Stock.

  In the event any Certificate shall have been lost, stolen or destroyed, upon
the making of an affidavit of that fact by the person claiming such Certificate
to be lost, stolen or destroyed and, if 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 letter of
transmittal and instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing shares of Norwest Common
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.

     covenants and agreements hereof to be performed or observed by such party;

          NOW, THEREFORE, the parties hereto, subject to the approval of the
shareholders of Company and of Merger Co., in consideration of the premises and
of the mutual covenants and agreements contained herein and of the benefits to

shall be merged with and into Company pursuant to the laws of the State of New

conditions of the merger of Merger Co. with and into Company, the mode of
carrying said merger into effect, the manner and basis of converting the shares
of Company Common Stock into shares of common stock of Norwest Corporation of
the par value of $1-2/3 per share ("Norwest Common Stock"), and such other
provisions with respect to said merger as are deemed necessary or desirable, as
follows:

          FIRST:  At the time of merger, Merger Co. shall be merged with and
into Company, one of the constituent corporations, which shall be the surviving
corporation, and the separate existence of Merger Co. shall cease and the name
of the surviving corporation shall continue to be American Republic Bancshares,
Inc.

          SECOND:  The Articles of Incorporation of Company at the time of
merger shall be and remain the Articles of Incorporation of the surviving
corporation until further amended according to law.

          THIRD:  The Bylaws of Company at the time of merger shall be and
remain the Bylaws of the surviving corporation until amended according to the
provisions of the Articles of Incorporation of the surviving corporation or of
said Bylaws.

          FOURTH:  The directors of Merger Co. at the time of merger shall be
and remain the directors of the surviving corporation and shall hold office from
the time of merger until their respective successors are elected and qualify.

          FIFTH:   The officers of Merger Co. at the time of merger shall be and
remain the officers of the surviving corporation and shall hold office from the
time of merger until their respective successors are elected or appointed and
qualify.

          SIXTH:  The manner and basis of converting the shares of Company
Common Stock into cash or shares of shares of Norwest Common Stock shall be as
follows:

     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 $26.50, the
          Adjusted Norwest Shares shall be the number determined by dividing (x)
          $27,950,000 plus the proceeds (net of commissions and similar

                                      A-36

<PAGE>
 
          expenses) received from the sale of the equity securities Company owns
          in First Security Corporation and in Wachovia Corporation by (y)
          $26.50;

          (b)  If the Norwest Measurement Price is equal to or less than $24.50,
          the Adjusted Norwest Shares shall be the number determined by dividing
          (x) $27,950,000 plus the proceeds (net of commissions and similar
          expenses) received from the sale of the equity securities Company owns
          in First Security Corporation and in Wachovia Corporation by (y)
          $24.50;

          (c)  If the Norwest Measurement Price is less than $26.50, but more
          than $24.50, the Adjusted Norwest Shares shall be the number
          determined by dividing (x) $27,950,000 plus the proceeds (net of
          commissions and similar expenses) received from the sale of the equity
          securities Company owns in First Security Corporation and in Wachovia
          Corporation by (y) 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 or 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, 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 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 have 

                                      A-37

<PAGE>
 
     received pursuant to such reclassification, recapitalization, split-up,
     combination, exchange of shares or 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 by the Secretary of State of the State of New
     Mexico; provided, however, that all of the following actions shall have
     been taken in the following order:

          a.  This Agreement shall be approved and adopted on behalf of  Merger
          Co. and Company in accordance with the New Mexico Business Corporation
          Act; and

          b.  Articles of merger (with this Agreement attached as part thereof)
          with respect to the merger, setting forth the 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 Secretary of State 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 corporate
     existence and identity of Company shall continue as the surviving
     corporation.

     2.  The merger shall have the other effects prescribed by Section 53-14-6
     of the New Mexico Business Corporation Act.

     NINTH:  The following provisions shall apply with respect to the merger

     1.  If at any time the surviving corporation shall consider or be advised
     that any further assignment or assurance in law or other action is
     necessary or desirable to vest, perfect or confirm in the surviving
     corporation the title to any property or rights of Merger Co. acquired or
     to be acquired as a result of the merger provided for herein, the proper
     officers and directors of Company and Merger Co. may execute and deliver
     such deeds, assignments and assurances in law and take such other action as
     may be necessary or proper to vest, perfect or confirm title to such
     property or right in the surviving corporation and otherwise carry out the
     purposes of this Agreement.

Norwest Corporation
Norwest Center
Sixth and Marquette
Minneapolis, MN  55479-1026

Attn:  Secretary

Gentlemen:

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

     Pursuant to an Agreement and Plan of Reorganization, dated as of June 6,
1994, (the "Reorganization Agreement"), between the Company and Norwest
Corporation, a Delaware corporation ("Norwest") it is contemplated that a
wholly-owned subsidiary of Norwest will merge with and into the Company (the
"Merger") and as a result, I will receive in exchange for each share of Common
Stock, par value $_____ per share, of the Company (the "Company Common Stock")
owned by me immediately prior to the Effective Time of the Merger (as defined in
the Reorganization Agreement), a number of shares of Common Stock, par value $1
2/3 per share, of Norwest ("Norwest Common Stock"), as more specifically set
forth in the Reorganization Agreement.

     I hereby agree as follows:


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


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

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

                                      A-40

<PAGE>
 
     Norwest's transfer agent shall be given an appropriate stop transfer order
and shall not be required to register any attempted transfer of the shares of
the Stock, unless the transfer has been effected in compliance with the terms of
this letter agreement.

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

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

                                    Sincerely,


                                    _________________________

                        OPINION OF MONTGOMERY SECURITIES

<PAGE>
                                                                June 6, 1994

Members of the Board of Directors
American Republic Bancshares, Inc.
101 South Main Street
Belen, NM  87002


Gentlemen:

     We understand that American Republic Bancshares, Inc., a New Mexico
corporation ("ARB"), and Norwest Corporation, a Delaware corporation
("Norwest"), propose to enter into an Agreement and Plan of Reorganization dated
June 6, 1994 (the "Merger Agreement"), pursuant to which (i) a wholly-owned
subsidiary of Norwest will be merged with and into ARB, with ARB as the
surviving corporation (the "Merger"), and (ii) ARB will make a distribution to a
trust (the "Trust") established for the benefit of its shareholders
(collectively, the "Transaction").  Pursuant to the Merger, as more fully
described in the Merger Agreement, we understand that each outstanding share of
the common stock, $1.00 par value per share, of ARB (the "ARB Common Stock")
will be converted into and exchangeable for the number of shares of the common
stock, $1-2/3 par value per share, of Norwest (the "Norwest Common Stock")
determined by dividing the Adjusted Norwest Shares (as defined in the Merger
Agreement) by the number of shares of the ARB Common Stock outstanding
immediately prior to the Effective Time (as defined in the Merger Agreement) of
the Merger.  In addition, as more fully described in the Merger Agreement, we
understand that prior to the Effective Date (as defined in the Merger Agreement)
of the Merger, ARB will distribute specified assets and related indebtedness to
the Trust.  The Norwest Common Stock and the beneficial interests in the Trust
to be received by the shareholders of ARB are together referred to as the
"Consideration."

     You have asked for our opinion as to whether the Consideration to be
received by the shareholders of ARB pursuant to the Transaction is fair to the
shareholders of ARB from a financial point of view, as of the date hereof.

     In connection with our opinion, we have, among other things: (i) reviewed
certain publicly available financial and other data with respect to ARB and
Norwest, including the consolidated financial statements for recent years and
the interim period to March 31, 1994, and certain other relevant financial and
operating data relating to ARB and Norwest made available to us from published
sources and from the internal records of ARB; (ii) reviewed the Merger
Agreement; (iii) reviewed certain historical market prices and trading volumes
of Norwest Common Stock as reported by the New York Stock Exchange; (iv)
compared ARB and Norwest from a financial point of view with certain other
companies in the banking industry which we deemed to be relevant; (v) considered
the financial terms, to the extent publicly available, of selected recent
business combinations of companies in the banking industry which we deemed to be
comparable, in whole or in part, to the Merger; (vi) reviewed and discussed with
representatives of the management of ARB and Norwest certain information of a
business and financial nature regarding ARB and Norwest, furnished to us by
them, including financial forecasts and related assumptions of ARB; (vii)
reviewed and discussed with representatives of the management of ARB the
September 26, 1991 appraisal obtained by ARB of certain assets being distributed
to the Trust by ARB; (viii) made inquiries regarding and discussed the
Transaction and the Merger Agreement and other matters related thereto with

                                               Members of the Board of Directors
                                                                    June 6, 1994
                                                                          Page 2



ARB's counsel; and (ix) performed such other analyses and examinations as we
have deemed appropriate.

     In connection with our review, we have not independently verified any of
the foregoing information with respect to ARB or Norwest, have relied on all
such information, and have assumed that all such information is complete and
accurate in all material respects.  With respect to the financial forecasts for
ARB provided to us by its management, we have assumed for purposes of our
opinion that the forecasts have been reasonably prepared on bases reflecting the
best available estimates and judgments of ARB's management at the time of
preparation as to the future financial performance of ARB and that they provide
a reasonable basis upon which we can form our opinion.  With respect to the
appraisal obtained by ARB of certain assets being distributed to the Trust by
ARB, we have assumed for purposes of our opinion that the appraisal reflects a
reasonable estimate as to the amount realizable by the Trust upon liquidation of
such assets.  We have also assumed that there have been no material changes in
ARB's or Norwest's assets, financial condition, results of operations, business
or prospects since the respective dates of their last financial statements made
available to us.  We have relied on advice of counsel to ARB as to all legal
matters with respect to ARB, the Transaction and the Merger Agreement.  We are
not experts in the evaluation of loan portfolios for purposes of assessing the
adequacy of the allowances for losses with respect thereto and have assumed that
such allowances for each of ARB and Norwest are in the aggregate adequate to
cover such losses.  In addition, we have not reviewed any individual credit
files, and we have not made an independent evaluation, appraisal or physical
inspection of the assets or individual properties of ARB or Norwest.  Finally,
our opinion is based on economic, monetary and market and other conditions as in
effect on, and the information made available to us as of, the date hereof.

     We have further assumed that the Transaction will be consummated in
accordance with the terms described in the Merger Agreement, without any further
amendments thereto, and without waiver by ARB of any of the conditions to its
obligations thereunder.

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

     Based upon the foregoing and in reliance thereon, it is our opinion that
the Consideration to be received by the shareholders of ARB pursuant to the
Transaction is fair to such shareholders from a financial point of view, as of
the date hereof.

     This opinion is furnished pursuant to our engagement letter, dated August
17, 1993, and is solely for the benefit of the Board of Directors of ARB.
Except as provided in such engagement letter, this opinion may not be used or
referred to by ARB, or quoted or disclosed to any person in any manner without
our prior written consent.  This opinion is not intended to be and shall not be
deemed to be a recommendation to any shareholder of ARB as to how such
shareholder should vote with respect to the Transaction.

                                                  Very truly yours,

                                                  /s/ Montgomery Securities
                                                  MONTGOMERY SECURITIES

                         NEW MEXICO STATUTES ANNOTATED


                          SECTIONS 53-15-3 AND 53-15-4

<PAGE>
 
     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 or 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 disclose 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.  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 corporation 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 

                                      C-1
<PAGE>
 
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 corporations, 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 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 of 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 such corporate action was
effected the fair value of such shares is agreed upon between any such
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.

     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 such 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
such 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.  

                                      C-2

<PAGE>
 
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 amendment thereof. The
judgment shall be payable to the holders of uncertified 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 shall cease to have any interest in such
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 the 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 such shareholders in failing to accept such
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 is [are] transferred, any new certificate issued
therefore shall bear similar notation, together with the name of the original
dissenting holder of the shares, and a transferee of 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
          ------------

         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, and (iii) to include any material
         information with respect to the plan of distribution not previously

         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.

determining any liability under the Securities Act of 1933, each filing of the

Securities Exchange Act of 1934) that is incorporated by reference in the

relating to the securities offered therein, and the offering of such securities

public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

  (d) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

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

  (f) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means.  This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

  (g) The undersigned registrant hereby undertakes to supply by means of a
posteffective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

Board of Directors

Minneapolis, Minnesota  55479-1000

Ladies and Gentlemen:

     In connection with the proposed registration under the Securities Act of
1933, as amended, of 1,266,000 shares of the common stock (the "Shares"), par
value $1-2/3 per share, of Norwest Corporation (the "Corporation"), a Delaware
corporation, which are proposed to be issued by the Corporation in connection
with the merger of a wholly owned subsidiary of the Corporation with American
Republic Bancshares, Inc. , an New Mexico corporation, (the "Merger"), 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

                              ______________, 19__



American Republic Bancshares, Inc.
101 South Main
Belen, New Mexico 87002
Attention:  James H. Foley,
            President and Chief Executive Officer


       Re:  Agreement and Plan of Reorganization dated June 6, 1994
            ("Agreement") by and between American Republic Bancshares, Inc., a
            New Mexico corporation ("ARBI"), and Norwest Corporation, a Delaware
            corporation ("Norwest")

Gentlemen:

We have acted as U.S. federal income tax counsel to ARBI in connection with the
Agreement, which contemplates the merger of a wholly-owned subsidiary of Norwest
with and into ARBI, with ARBI as the surviving corporation.  Pursuant to the
Agreement, each share of the common stock, $1.00 par value ("ARBI Common
Stock"), outstanding immediately prior to the effective 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
common stock, $1-2/3 par value ("Norwest Common Stock") determined in the manner
provided in Section 1(a) of the Agreement.  This opinion is being rendered
pursuant to Section 6(h) of the Agreement.  Capitalized terms not otherwise
defined herein shall have the meanings ascribed to them in the Agreement.

In our capacity as tax counsel to ARBI, we have examined executed counterparts
of the Agreement.  We have also examined originals or copies of the Articles of
Incorporation and Bylaws of ARBI and certain resolutions adopted by the Board of
Directors of ARBI.  In addition, we have relied on certificates of officers of
ARBI as to certain matters of fact relating to this opinion.  We have considered
the applicable provisions of the Internal Revenue Code of 1986, as amended
("Code"), Treasury regulations (including temporary and proposed), relevant
judicial authorities, pronouncements of the Internal Revenue Service (including
private letter rulings addressing facts similar to those described in the
Agreement but issued to unrelated parties), and have made such other
investigations of law and as we have deemed necessary and relevant as a basis
hereof.  We have assumed the genuineness of all signatures, the authenticity of
all documents and records submitted to us as originals, the conformity to
original documents and records of all documents and records submitted to us as
copies, and the truthfulness of all statements of act contained therein.
Moreover, we have assumed the due authorization, execution and delivery of the
Agreement by Norwest.

In addition to the above-referenced assumptions, in rendering our opinion we 
have also assumed that (i) Norwest will merge ARBI's wholly-owned bank 
subsidiary (the "Bank") into Norwest Bank New Mexico, N. A., (ii) such merger 
will qualify as a reorganization under Section 368(a) of the Code, and (iii) the
successor corporation in such merger, and the successor corporation in the 
Merger, will each respectively continue to use a significant part of the 
historic business assets of the Bank and ARBI in the conduct of their
businesses. We have further assumed that Norwest has not owned any shares of
stock in ARBI during the past five years.

Based upon the foregoing and subject to the limitations and assumptions set
forth herein, and having due regard for such legal considerations as we deem
relevant, we are of the opinion that:

     1.   The Merger will, under current law, constitute a tax-free
          reorganization under Code (S) 368(a), and Norwest and ARBI will each
          be a party to the Reorganization within the meaning of Code (S)
          368(b).

     2.   ARBI will not recognize gain or loss as a result of the Merger.

     3.   No gain or loss will be recognized by holders of ARBI Common Stock as
          a result of the exchange of such shares for shares of Norwest Common
          Stock pursuant to the Merger except that gain or loss will be
          recognized on the receipt of cash if any, received in lieu of
          fractional shares.  Any cash received by a shareholder of ARBI in lieu
          of a fractional share or pursuant to the exercise of dissenters'
          rights will be treated as a receipt in exchange for such shares and
          not as a dividend, and any gain or loss recognized as a result of the
          receipt of such cash, will be capital gain or loss equal to the
          difference between the cash received and the portion of the
          shareholder's basis in ARBI Common Stock allocable to such fractional
          share interest.

     4.   The tax basis of the shares of Norwest Common Stock received by each
          shareholder of ARBI will equal the tax basis of such shareholder's
          shares of ARBI Common Stock (reduced by any amount allocable to any
          fractional share interest for which cash is received) exchanged in the
          Merger.

     5.   The holding period for the shares of Norwest Common Stock received by
          each shareholder of ARBI will include the holding period for the
          shares of ARBI Common Stock such shareholder exchanged in the Merger.

     6.   ARBI's creation of the Liquidating Trust (the "Trust") and subsequent
          distribution of the Trust interests to its shareholders will be
          treated for federal income tax purposes in the following manner:
          First, ARBI will be viewed as having made a dividend-type distribution
          to its shareholders of undivided interests in the assets of the Trust
          (the "Trust Corpus").  Each shareholder will include in his or her
          income the value of such distribution under the dividend rules, and
          will take an income tax basis in his or her proportionate share of the
          Trust Corpus equal to the fair market value of such proportionate
          share.  Second, the shareholders will be viewed as the owners of the
          Trust, thus causing the Trust to come within the grantor trust income
          tax rules.  These rules generally provide that the existence of a
          grantor trust is ignored for federal income tax purposes, and each
          shareholder-beneficiary is deemed to directly own his or her
          proportionate share of the Trust Corpus.  Third, on the subsequent
          sale of the Trust Corpus, each shareholder-beneficiary will compute
          his or her gain or loss as if he or she had individually sold his or
          her proportionate share of the Trust Corpus.  Each shareholder-
          beneficiary would include in his or her individual tax return the gain
          or loss from such sale, measured by the difference between the amount
          realized on such sale (i.e., the shareholder-beneficiary's
          proportionate share of the sales proceeds for the Trust Corpus) and
          the shareholder-beneficiary's tax basis in his or her proportionate
          share of the Trust Corpus.

The foregoing opinion is, with your concurrence, predicated on and is limited to
the relevant laws of the United States of America, and we render no opinion with
respect to the law of any other jurisdiction.  This opinion is solely for your
benefit and may not be relied upon by any other person.

We hereby consent to the filing of this opinion with the Securities and Exchange
Commission as Exhibit 8 to the Registration Statement of Norwest on Form S-4,
filed  _______, 1994 (File No. _____) and to all reference to our name therein.


                              Very truly yours,

                          AGREEMENT AND DECLARATION OF
                             ARBI LIQUIDATING TRUST



     This Agreement and Declaration of the ARBI Liquidating Trust ("Agreement")
is by and between American Republic Bancshares, Inc., a New Mexico Corporation
("ARBI"), and _________________, an individual residing in ________________
("Trustee"), who agree as follows:

     1.   Introduction.  At a duly convened meeting of the Board of Directors of
ARBI held June 4, 1994, the Board of Directors approved the merger ("Merger") of
ARBI with a wholly-owned subsidiary of Norwest Corporation, a Delaware
corporation ("Norwest"), pursuant to the terms and conditions of an Agreement
and Plan of Reorganization dated as of June 6, 1994 by and between ARBI and
Norwest ("Reorganization Agreement"). At a duly convened meeting of the
shareholders of ARBI on ___________, 1994, the shareholders of ARBI approved the
terms of the Reorganization Agreement and the Merger. The Reorganization
Agreement requires, among other things, that prior to the effective date of the
Merger ARBI distribute or cause to be distributed, at fair market value, to an
irrevocable trust established for the exclusive ratable benefit of all the
shareholders of record of ARBI as of the date of the distribution (i) all of the
artwork owned by ARBI or any ARBI subsidiary listed on Schedule I hereto and any
indebtedness incurred in purchasing such artwork, (ii) all equity securities of
New Mexico Financial Corporation owned by ARBI or any ARBI subsidiary, and (iii)
$50,000 in cash ("Trust Assets"). This Agreement sets forth the terms and
conditions on which the trust required by the Reorganization Agreement is to
organized, administered and terminated.

     2.   The Trust.
          --------- 

          2.1  Establishment of the Trust.  Subject to the terms and conditions
of this Agreement and the laws of the State of New Mexico, there is hereby
established by ARBI on behalf of its shareholders, a trust ("Trust") for the
exclusive ratable benefit of each person who was a shareholder of record of ARBI
on the date hereof as evidenced by the list of shareholders attached hereto as
Exhibit A ("Shareholders"). Concurrently with the establishment of this Trust,
ARBI is delivering to the Trustee, on behalf of the Shareholders, all of the
Trust Assets, as required by the Reorganization Agreement.

          The Trustee is hereby authorized and appointed to act for the benefit
of all of the Shareholders and shall hereby succeed to all the right, title and
interest of ARBI in and to all of the Trust Assets and the earnings thereon and
distributions in respect thereof, including but not limited to (i) any dividends
or other payments or distributions to which any Shareholder may be entitled who
cannot be located, (ii) all cash, notes receivable and other Trust Assets of
ARBI, and (iii) any uncollected claims, contingent assets (including claims for
refund of taxes or for proceeds of insurance in respect of the Trust assets).

          2.2  Purposes of the Trust.  The purposes of this Trust are to (i)
receive the distribution from ARBI of the Trust Assets and any additional assets
which ARBI may
<PAGE>
 
distribute to the Trust pursuant to the Reorganization Agreement or otherwise,
(ii) receive any and all other assets which may come into the possession of the
Trustee, (iii) cause, to the extent practicable, the Trust Assets and such other
assets to be converted into cash, (iv) invest the cash proceeds resulting from
the collection, liquidation or conversion into cash of the Trust Assets until
such assets can be distributed pursuant to the terms hereof, (v) discharge all
debts, liabilities, and obligations assumed by the Trust pursuant to the
Reorganization Agreement or incurred by the Trust in connection with its
operation and termination, and (vi) distribute, in one or more distributions, to
the Shareholders as promptly as practicable all assets remaining after the
payment or the provision for payment of the obligations and expenses of this
Trust. The Trust is expressly prohibited from engaging, directly or indirectly,
in any form of trade or business for profit. Furthermore, under no circumstances
shall any of the Trust Assets or any other assets of the Trust held by the
Trustee be returned to ARBI.

          2.3  Interests in the Trust.  On the establishment of this Trust, each
shareholder shall have a fractional interest ("Interest[s]") in the net assets
held in this Trust, and in any distribution from this Trust which is made to all
the Shareholders, equal to the ratio which the number of shares of capital stock
of the Company held of record by such Shareholder as of the date hereof ("Record
Date") bears to the total number of shares of capital stock of the Company
issued and outstanding as of the Record Date.  The Interest, expressed in
percentage or fractional form, of each Shareholder initially shall be as set
forth on Exhibit "A."  The Trustee shall establish and maintain a ledger
("Interest Ledger") reflecting the Interest, expressed in percentage or in
fractional form, of each Shareholder.  The Trustee shall record a change in or
transfer of all or any portion of any Shareholder's Interest in this Trust in
the Interest Ledger only in the event that such change or transfer shall be one
permitted or authorized pursuant to Section 2.4 below, and the Trustee shall
have received from the transferor (or his representative), such documents of
assignment and such evidence of identity and capacity to transfer as the Trustee
in its discretion may deem necessary.  Until such time as the Trustee shall have
received evidence (in a form suitable to the Trustee in accordance with Section
2.4 below) of a permitted change in any Shareholder's Interest, the Trustee may
rely with full immunity on the fact that each Shareholder continues to own the
interest in the Trust Assets set forth in the Interest Ledger opposite his name.
All distributions of Trust Assets made to the Shareholders by the Trustee in
accordance with this Agreement shall be made to the Shareholders specified in
the Interest Ledger, pro rata, in accordance with their respective Interests.

          2.4  Non-Transferability of Interests in the Trust.  The Interests
created in this Trust shall neither be negotiable, assignable or transferable,
except for transfers effected by death (including both the transfer of title
from the decedent to his estate and from the decedent's estate to his
distributees or legatees), divorce, bankruptcy or other transfer effected by
operation of law.
