                                    SUMMARY


       The following summary is not intended to be complete and is qualified in
  all respects by the more detailed information included in this Proxy
  Statement-Prospectus, the Appendices hereto, and the documents incorporated by
  reference herein.  Shareholders of BMS are urged to read carefully the entire
  Proxy Statement-Prospectus, including the Appendices.  As used in this Proxy
  Statement-Prospectus, the terms "Norwest" and "BMS" refer to such entities,
  respectively, and where the context requires, such entities and their
  respective subsidiaries.  All information concerning Norwest included in this
  Proxy Statement-Prospectus has been furnished by Norwest, and all information
  concerning BMS included in this Proxy Statement-Prospectus has been furnished
  by BMS to Norwest for incorporation herein.

  THE COMPANIES

       Norwest Corporation

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

       At September 30, 1993, Norwest had consolidated total assets of $50.4
  billion, total deposits of $31.6 billion, and total stockholders' equity of
  $3.4 billion.  Based on total assets at September 30, 1993, Norwest was the
  13th largest commercial banking organization in the United States.  Norwest
  recently completed, through its subsidiary GST Co., the acquisition of First
  United Bank Group, Inc. ("First United"), a bank holding company headquartered
  in Albuquerque, New Mexico, in exchange for 17,785,447 shares (exclusive of
  shares reserved for stock options) of Norwest Common Stock.  First United
  owned and operated banks in New Mexico and Texas as well as other subsidiaries
  engaged in related businesses, and had $3.5 billion in assets at September 30,
  1993.  See also "RECENT OPERATING RESULTS OF NORWEST."

       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 other financial institutions having aggregate total
  assets at September 30, 1993, of approximately $546 million (excluding BMS).
  Certain of these acquisitions have received regulatory approval and are
  expected to be completed in the first quarter of 1994.  The remaining
  acquisitions are subject to the approval of regulatory authorities and are
  also expected to be

                                       7
<PAGE>


  completed in the first quarter of 1994.  None of these acquisitions are
  significant to the financial statements of Norwest, either individually or in
  the aggregate.

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

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

       Bank of Montana System

       BMS is a bank holding company registered under the BHC Act and
  headquartered in Great Falls, Montana.  BMS owns all of the outstanding
  capital stock of Bank of Montana, a bank chartered under the laws of Montana
  with 17 branches in 15 Montana communities.  BMS also owns all of the
  outstanding capital stock of Montana Bancsystem, Inc., a bank holding company
  registered under the BHC Act and headquartered in Billings, Montana ("MBI"),
  which in turn owns approximately 99.6% of the outstanding capital stock of
  Montana Bank, a bank chartered under the laws of Montana with 12 branches in
  12 Montana communities.  At September 30, 1993, BMS had consolidated total
  assets of $797.0 million and total shareholders' equity of $55.2 million.
  Through Bank of Montana and Montana Bank, BMS offers a range of traditional
  banking services, including commercial, retail and agricultural lending,
  credit cards, data processing and other financial services.  BMS is a Montana
  corporation.  Its main office is located at 410 Central Avenue, Great Falls,
  Montana 59403, and its telephone number is (406) 727-3100.  See "INFORMATION
  ABOUT BMS--Business."

  THE MERGER

       The Merger Agreement provides for the merger of a wholly owned subsidiary
  of Norwest with BMS, with BMS as the surviving corporation.  Upon consummation
  of the Merger, each share of BMS Common Stock that was outstanding immediately
  prior to consummation of the Merger (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 (the "Exchange Ratio")
  determined by dividing the Adjusted Norwest Shares (as defined below) by the
  number of shares of BMS Common Stock then outstanding.  The "Adjusted Norwest
  Shares" means 4,200,000 subject to reduction prior to consummation of the
  Merger as a result of certain severance and bonus payments, certain share
  purchases by BMS's employee stock ownership plan (the "ESOP"), certain
  payments to Norwest for assistance with the operations, data processing and
  internal audit functions of BMS, certain losses identified in the general
  ledger balancing and account reconciliation process and certain environmental
  remediation costs, if any.  See "THE MERGER--Terms of the Merger."

  THE SPECIAL MEETING AND VOTE REQUIRED

       The Special Meeting of BMS shareholders to consider and vote on the
  Merger will be held on _______, _________, 1994, at __:__ .m., local time, at
  5500 Wayzata Boulevard, Suite 145, Golden Valley, Minnesota.  Only holders of
  record of BMS Common Stock at the close of business on ______________, 1994,
  will be entitled to vote at the Special Meeting.  At such date, there were
  2,014,676 shares of BMS Common Stock outstanding.  Each share of BMS Common
  Stock is entitled


                                       8
<PAGE>


  to one vote.  For additional information relating to the Special Meeting, see
  "MEETING INFORMATION."

       Approval of the Merger Agreement requires the affirmative vote of the
  holders of two-thirds of the outstanding shares of BMS Common Stock.  See
  "MEETING INFORMATION--Record Date; Vote Required."

       As of the record date for the Special Meeting, directors and officers of
  BMS and their affiliates owned beneficially or controlled the voting of an
  aggregate of 1,717,648 shares of BMS Common Stock, or 85.3% of the shares of
  BMS Common Stock outstanding on that date.  BMS's directors and officers have
  informed BMS that they intend to vote all of their shares in favor of the
  Merger Agreement.  ACCORDINGLY, THE DIRECTORS AND OFFICERS OF BMS HAVE THE
  ABILITY TO APPROVE THE MERGER WITHOUT THE VOTE OF THE REMAINING BMS
  SHAREHOLDERS.  At the record date, directors and executive officers of Norwest
  did not own beneficially any shares of BMS Common Stock.  At the record date,
  Norwest Capital Management & Trust Co., Montana, a subsidiary of Norwest, held
  in its fiduciary capacity, and had sole discretionary authority to vote, 2,000
  shares of BMS Common Stock.  See "MEETING INFORMATION--Record Date; Vote
  Required" and "MEETING INFORMATION--Principal Shareholders and Security
  Ownership of Management."

  REASONS FOR THE MERGER

       After careful consideration and review, the BMS Board of Directors (the
  "Board") has reached the conclusion that the terms of the Merger are in the
  best interest of the BMS shareholders.  The Board believes that the terms of
  the Merger are reasonable and will enhance the value of the BMS shareholders'
  investment.  The decision to merge with Norwest was reached by the Board based
  on their analysis of several critical factors.  These factors included the
  fact that, with the rapidly changing environment in the banking industry, BMS
  would benefit from the association with a larger banking organization and its
  resources.  Also, in reaching its decision, the Board considered, among other
  things, the current market price for Norwest Common Stock, Norwest's dividend
  payments, book value, recent earnings, and management ability, the
  compatibility of operating philosophies, the report and opinion of D.A.
  Davidson & Co. ("D.A. Davidson"), financial advisor to BMS, the anticipated
  income tax consequences to the BMS shareholders, the terms of the Merger
  Agreement and the other proposals it received regarding potential business
  combinations.  Norwest's Board of Directors believes that its acquisition of
  BMS will strengthen its existing presence in Montana and lower its costs by
  combining certain business units.  See "THE MERGER--Background of and Reasons
  for the Merger."

  RECOMMENDATION OF THE BOARD OF DIRECTORS OF BMS

       THE BOARD OF DIRECTORS OF BMS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS OF
  BMS VOTE FOR APPROVAL OF THE MERGER.  For information concerning the interests
  in the Merger of certain members of the BMS Board of Directors and management
  who are also principal shareholders of BMS, see "THE MERGER--Interests of
  Certain Persons in the Merger; Certain Transactions."

  OPINION OF BMS FINANCIAL ADVISOR

       D.A. Davidson has rendered its opinion to the Board of Directors of BMS
  as to the fairness, from a financial point of view, of the consideration to be
  received by BMS's shareholders in the Merger.  The full text of the written
  opinion of D.A. Davidson, which sets forth the procedures followed,
  assumptions made and other matters considered is attached as Appendix C to
  this Proxy Statement-Prospectus and should be read in its entirety.  See "THE
  MERGER--Opinion of BMS Financial Advisor."

  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 an executed Agreement and Plan of
  Merger and Articles of Merger are filed with the Secretary of State of the
  State of Montana (the "Effective Date of the Merger") at 11:59 p.m.,
  Minneapolis, Minnesota time (the "Effective Time of the Merger").  Such filing
  shall be made not later than 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, but no earlier than February 6, 1994
  (the "Closing Date") and the time at which such filing will be made is
  hereinafter referred to as the "Time of Filing."  The parties have agreed to
  use their best efforts to cause the Merger to be completed within ten business
  days after the satisfaction or waiver of the conditions set forth in the
  Merger Agreement that the Merger Agreement be approved by the BMS
  shareholders, that all regulatory approvals be received without unduly
  burdensome conditions, and that all waiting and appeal periods be expired.
  The closing of the Merger will occur on the Effective Date of the Merger.  The
  parties expect the Merger to become effective as soon as practicable following
  shareholder approval of the Merger.  See "THE MERGER--Effective Date and Time
  of the Merger" and "THE MERGER--Conditions to the Merger."

  CONDITIONS AND TERMINATION

       The respective obligations of Norwest and BMS 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 BMS, receipt by BMS of certain tax opinions
  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 of
  Filing, whether prior to or after approval by the BMS shareholders, by either
  party under certain specified conditions, including if the Merger shall not
  have been consummated by April 15, 1994, unless such failure of consummation
  shall be due to the failure of the party seeking termination to perform its
  respective covenants and agreements under the Merger Agreement.  In addition,
  BMS has the right to terminate the Merger Agreement upon giving written notice
  to Norwest no later than 5:00 p.m. Minneapolis time on the first business day
  immediately preceding the scheduled Closing Date in the event that the average
  of the closing prices of a share of Norwest Common Stock as reported on the
  consolidated tape of the NYSE during the period of twenty trading days ending
  at the end of the third trading day immediately preceding the Closing Date
  (the "Norwest Measurement Price") is less than $23.50.  See "THE MERGER--
  Waiver, Amendment, and Termination."

                                       10

  ACCOUNTING TREATMENT

       It is anticipated that the Merger will be accounted for as a pooling of
  interests of Norwest and BMS 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") under Sections 3 and
  4 of the BHC Act.  The Merger may not be consummated until the 30th day
  following the date of the Federal Reserve Board approval, during which time
  the United States Department of Justice may challenge the Merger on antitrust
  grounds.  The commencement of an antitrust action could stay the effectiveness
  of the Federal Reserve Board's approval unless a court specifically orders
  otherwise.

       Norwest filed applications with the Federal Reserve Board for approval of
  the Merger on November 2, 1992.  As a result of an analysis of the probable
  competitive effects of the Merger, including conversations with the staff of
  the Federal Reserve System, in the application to the Federal Reserve Board,
  Norwest committed to sell two branches of Bank of Montana and one branch of
  Montana Bank to competitively suitable acquirors.  Therefore the sale of such
  branches will be a condition to any approval of the Merger by the Federal
  Reserve Board.  There can be no assurance that the Federal Reserve Board will
  approve the Merger and, if the Merger is approved, there can be no assurance
  concerning the date of such approvals.  There also can be no assurance that
  Norwest will be successful in selling such branches or that any such approval
  will not contain other conditions or requirements which could cause such
  approval to fail to satisfy the conditions to the consummation of the Merger.
  Furthermore, there can be no assurance that the Department of Justice will not
  challenge the Merger or, if such a challenge is made, what the result will be.
  See "THE MERGER--Conditions to the Merger" and "THE MERGER--Regulatory
  Approvals."

       Effective October 1, 1993, the Montana Bank Act was amended to permit a
  bank holding company with headquarters in certain states outside of Montana to
  acquire a bank located in Montana if the interstate banking laws of the state
  in which the headquarters are located are substantially similar to those of
  Montana.  The Montana Bank Act also requires that certain documentation be
  filed with the Montana Department of Commerce and permits the Montana
  Department of Commerce to intervene in or take other action in a federal
  banking regulatory authority proceeding.  Norwest has filed the required
  documentation and believes that the Montana and Minnesota interstate banking
  laws are substantially similar.  There can be no assurance, however, that the
  Montana Department of Commerce will not intervene in or take other action with
  respect to the proposed Merger.  See "THE MERGER--Regulatory Approvals."

  MANAGEMENT AND OPERATIONS AFTER THE MERGER

       Following the Merger, Norwest intends to operate BMS's bank affiliates at
  their present locations and to provide products and services offered by
  Norwest affiliates. In its application to the Federal Reserve Board, Norwest
  has committed to sell two branches of Bank of Montana and one branch of
  Montana Bank to competitively suitable acquirors.  Norwest also intends to
  sell the escrow business of BMS. See "THE MERGER--Management and Operations
  After the Merger."

                                       11
<PAGE>


  INTERESTS OF CERTAIN PERSONS IN THE MERGER; CERTAIN TRANSACTIONS

       Certain members of the Board of Directors of BMS and executive officers
  of BMS, who are also principal shareholders of BMS, have interests in the
  Merger that are in addition to or different from the interests of BMS
  shareholders generally.  Also, at the time of negotiating the terms of the
  Merger, BMS, certain of its bank subsidiaries and certain of its directors and
  executive officers, had various lending, correspondent-banking and other
  account relationships with one or more of Norwest's affiliates.  See "THE
  MERGER--Interests of Certain Persons; Certain Transactions" and "INFORMATION
  ABOUT BMS--Business--Recent Developments."  The Board of Directors of BMS was
  aware of such interests in the Merger and such pre-existing relationships and
  considered such interests and relationships, among other matters, in
  recommending approval of the Merger and the transactions contemplated thereby.

  CERTAIN DIFFERENCES IN RIGHTS OF SHAREHOLDERS

       Upon consummation of the Merger, the BMS shareholders will become Norwest
  stockholders.  As a result, their rights as shareholders, which are now
  governed by Montana state law and by the Restated Articles of Incorporation
  and the Bylaws of BMS, will be governed by Delaware state law and the
  Certificate of Incorporation and the By-Laws of Norwest.  See "THE MERGER--
  Certain Differences in Rights of Shareholders" for a summary of certain
  material differences between the rights of holders of BMS Common Stock and the
  rights of holders of Norwest Common Stock.

  DISSENTERS' RIGHTS

       Any shareholder of BMS may, as an alternative to receiving the
  consideration specified in the Merger Agreement, dissent from the Merger and
  obtain payment of the fair value of such shareholder's BMS Common Stock
  pursuant to Sections 35-1-826 through 35-1-839 of the Montana Business
  Corporation Act (the "MBCA").  Any BMS shareholder contemplating exercising
  the right to demand such payment should carefully review Sections 35-1-826
  through 35-1-839 of the MBCA, a copy of which is included as Appendix B to
  this Proxy Statement-Prospectus, and in particular the required procedural
  steps.  A shareholder who fails to comply with these procedural requirements
  may lose the right to dissent and obtain payment of the fair value of such
  shareholder's BMS Common Stock.  See "THE MERGER--Dissenters' Rights."

  CERTAIN FEDERAL INCOME TAX CONSEQUENCES

       The Merger is intended to qualify as a reorganization within the meaning
  of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal Revenue Code of
  1986, as amended (the "Code").  If the Merger so qualifies, (i) no gain or
  loss will be recognized by holders of BMS Common Stock upon their receipt of
  Norwest Common Stock in exchange for their shares of BMS Common Stock, except
  with respect to cash received in lieu of fractional shares, (ii) the income
  tax basis of the Norwest Common Stock received generally will be equal to the
  income tax basis of the BMS Common Stock surrendered, and (iii) the holding
  period of the Norwest Common Stock received generally will include the holding
  period of the BMS Common Stock surrendered.  BMS's obligation to consummate
  the Merger is conditioned upon its receipt of an opinion from its counsel to
  the effect that the Merger will qualify as a reorganization within the meaning
  of Sections 368(a)(1)(A) and

                                       12
<PAGE>

  368(a)(2)(E) of the Code.  EACH HOLDER OF BMS COMMON STOCK  IS URGED TO

  INCOME TAX CONSEQUENCES OF THE MERGER, AS WELL AS ANY APPLICABLE STATE, LOCAL,

  PARTICULAR FACTS AND CIRCUMSTANCES.  See "THE MERGER--Conditions to the
  Merger" and "THE MERGER--Certain Federal Income Tax Consequences."

  RESALE OF NORWEST COMMON STOCK

       The shares of Norwest Common Stock issuable to shareholders of BMS upon
  consummation of the Merger have been registered under the Securities Act of
  1933, as amended (the "Securities Act").  Such shares may be traded freely and
  without restriction by those shareholders not deemed to be "affiliates" of BMS
  or Norwest as that term is defined in the rules under the Securities Act.
  Norwest Common Stock received by those shareholders of BMS who are deemed to
  be "affiliates" of BMS may be resold without registration as provided for by
  Rule 145 under the Securities Act, or as otherwise permitted under the
  Securities Act.  See "THE MERGER--Resale of Norwest Common Stock."

  MARKETS AND MARKET PRICES

       Norwest Common Stock is listed on the NYSE and the CHX.  On September 10,
  1993, the last trading day preceding public announcement of the proposed
  Merger, the closing price per share of Norwest Common Stock was $ 27.25 and on
  __________, 1994, the price was $_________.  There is no established public
  trading market for BMS Common Stock.  See "INFORMATION ABOUT BMS--Business-
  Market Price of and Dividends on BMS Common Stock."  BMS shareholders 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 months.  As a result, the market value of the
  Norwest Common Stock that BMS shareholders ultimately receive in the Merger
  could be more or less than its market value on the date of this Proxy
  Statement-Prospectus.  Because the Exchange Ratio is fixed except for certain
  specified reductions, BMS shareholders will not be compensated for decreases
  in the market price of Norwest Common Stock which could occur before the
  Effective Time of the Merger.  See "THE MERGER--Waiver, Amendment, and
  Termination" for a discussion of BMS's right to terminate the Merger Agreement
  if the Norwest Measurement Price is below $23.50.  No assurance can be given
  concerning the market price of Norwest Common Stock before or after the
  Effective Date of the Merger.

(1) 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.

(2) 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.

(3) 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.

  VOTING AND REVOCATION OF PROXIES

       Shares of BMS 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 BMS 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 BMS 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.  An abstention or a failure to vote
  (including broker non-votes) will have the same effect as a vote against the
  Merger Agreement.

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

  SOLICITATION OF PROXIES

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

       HOLDERS OF BMS COMMON STOCK ARE REQUESTED TO COMPLETE, DATE, AND SIGN THE
  ACCOMPANYING PROXY AND RETURN IT PROMPTLY TO BMS 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.

                                       23
<PAGE>


  BACKGROUND OF AND REASONS FOR THE MERGER

       BMS

       Prior to 1993, bank holding companies not resident in the State of
  Montana were prohibited from acquiring banks located in Montana.  On April 11,
  1993, the Governor of Montana signed into law a bill permitting limited
  interstate banking in Montana.  This legislation enabled bank holding
  companies in Colorado, Idaho, Minnesota, North Dakota, South Dakota,
  Wisconsin, and Wyoming (the "Reciprocal States"), to own and operate banks in
  Montana, subject to certain restrictions.  The interstate banking law became
  effective on October 1, 1993.  For a further discussion of the interstate
  banking law, see "Regulatory Approvals" and "INFORMATION ABOUT BMS--Business--
  Supervision and Regulation."

       As a consequence of this change in the law, during the second quarter of
  1993, BMS received inquiries from and on behalf of regional bank holding
  companies located in Reciprocal States regarding possible business
  combinations with BMS.  In response to such inquiries, John Morrison, Chairman
  of the Board of Directors of BMS, held preliminary discussions with certain
  regional bank holding companies (including Norwest) located in the Reciprocal
  States regarding possible business combinations with BMS.  These preliminary
  discussions resulted in three proposals to acquire all or a portion of BMS
  through various forms of transactions, including an offer from Norwest in the
  form of a letter of intent.  In order to induce Norwest to continue
  negotiating with BMS and to indicate to Norwest its interest in  discussing in
  more detail the possible acquisition of BMS by Norwest, BMS entered into a
  letter of intent with Norwest on June 22, 1993.  The letter of intent outlined
  the general terms of a proposed acquisition of BMS by Norwest, required the
  immediate preparation of a definitive merger agreement and prohibited BMS from
  soliciting proposals from other persons regarding an acquisition of BMS during
  a 23-day period ending July 15, 1993.  The letter of intent, however, did not
  obligate BMS to be acquired by Norwest nor did it prohibit BMS from soliciting
  new proposals or negotiating with other parties after the letter of intent
  expired which was initially on July 15, 1993.  Management of BMS believed it
  was in the best interest of BMS to have the opportunity to review the terms of
  the definitive merger agreement before presenting the Norwest offer to the
  Board of Directors of BMS.  Subsequent to the July 12 meeting of the Board of
  Directors (discussed below), the letter of intent was amended to extend its
  term beyond the initial July 15 termination date.

       During this time, BMS had existing relationships with certain affiliates
  of Norwest including a line of credit and various correspondent-bank
  arrangements, such as demand deposit accounts, brokerage and safekeeping
  arrangements, repurchase agreements, and secured and unsecured "Fed Funds"
  credit lines.  Certain of the borrowings under the existing line of credit
  arose in connection with prior acquisitions by BMS, including the acquisition
  of MBI.  Also, part of the required financing for the acquisition of MBI by
  BMS originally was to have been provided through the purchase of convertible
  preferred stock by Norwest.  Due to regulatory issues raised by the staff of
  the Federal Reserve System, Norwest's agreement to purchase the convertible 
  preferred stock was terminated in February of 1993.  To replace the proceeds
  from such financing, certain directors of BMS  purchased newly issued BMS
  Common Stock.  See "INFORMATION ABOUT BMS--Business--Recent Developments" for
  a discussion of the acquisition of MBI and the related financing.  Also, see
  "THE 

                                       24
<PAGE>


  MERGER--Interests of Certain Persons in the Merger; Certain Transactions" for
  a discussion of certain other commercial relationships between certain
  affiliates of Norwest and certain affiliates of BMS and for a discussion of
  the loans made by affiliates of Norwest to certain directors of BMS in
  connection with the financing of the acquisition of MBI.

       In anticipation of the consideration by the Board of Directors of BMS of
  the three acquisition  proposals from the regional bank holding companies, BMS
  engaged D.A. Davidson, an investment banking firm located in Great Falls,
  Montana, to assist the Board in evaluating BMS's strategic options.  At a
  special meeting of the Board held on July 12, 1993, management of BMS
  presented to the Board for its consideration the three acquisition proposals.
  The Board considered each proposal, as well as other alternative strategies to
  maximize shareholder value, including capital-raising strategies, continuing
  as an independent entity or a combination of such strategies.  The Board
  resolved to pursue further negotiations with Norwest regarding the possible
  acquisition of BMS through a merger and directed management of BMS and its
  financial and legal advisors to conduct further discussions and analysis.

       During the period from late July through early September 1993, Norwest
  conducted its due diligence investigation of BMS and agreement on the terms of
  the proposed merger with Norwest and the related merger agreement was reached
  after extensive negotiations between representatives of BMS and Norwest.  Also
  during this time, management of BMS received unsolicited revised proposals
  from the two other regional bank holding companies that had previously made
  acquisition proposals.   These proposals were evaluated by management of BMS.
  The Board held a second special meeting on September 7, 1993 to discuss the
  terms of the resulting proposed merger agreement with Norwest and the
  transactions contemplated thereby, and to discuss the other unsolicited
  proposals.  At this meeting,  D.A. Davidson discussed with the Board its
  opinion as to the fairness, from a financial point of view, of the proposed
  consideration to be received by BMS's shareholders in the proposed merger.
  See "Opinion of BMS Financial Advisor" for a discussion of the factors
  considered and the analytical methods employed by D.A. Davidson in reaching
  such conclusion. By unanimous vote at the September 7 special meeting, the
  Board approved the proposed form of merger agreement, subject to the final
  negotiation thereof by certain officers of BMS and approved the transactions
  contemplated thereby.  The Merger Agreement was executed by BMS and Norwest on
  September 13, 1993.

       The decision to merge with Norwest was reached by the Board based on
  their analysis of several critical factors.  These factors included the fact
  that, with the rapidly changing environment in the banking industry, BMS would
  benefit from the association with a larger banking organization and its
  resources.  Additionally, in light of the regional and national wave of bank
  consolidations, the current interest rate environment, the new legislation in
  Montana allowing limited interstate banking and the favorable strategic market
  position of BMS, the Board concluded that a business combination with a larger
  regional bank holding company would be the most advantageous method of
  maximizing shareholder value.  An added benefit considered by the Board was
  that the shareholders of BMS would have the diversification of owning stock in
  a publicly traded and geographically diverse banking organization.  Also, in
  reaching its decision, the Board considered, among other things, the current
  market price for Norwest Common Stock, 

                                       25
<PAGE>


  Norwest's dividend payments, book value, recent earnings, and management
  ability, the compatibility of operating philosophies, the D.A. Davidson report
  and opinion, the anticipated income tax consequences to the BMS shareholders,
  the terms of the Merger Agreement and the other proposals it received
  regarding potential business combinations.

       After careful consideration and review, the BMS Board of Directors has
  reached the conclusion that the terms of the Merger are in the best interest
  of the BMS shareholders.  The  Board believes that the terms of the Merger are
  reasonable and will enhance the value of the BMS shareholders' investment on a
  tax-free basis.  See "THE MERGER--Certain Federal Income Tax Consequences."
  Also, because only a very limited market currently exists for the purchase and
  sale of BMS Common Shares, the exchange of the BMS Common Shares for Norwest
  Common Stock will provide the BMS shareholders with a more liquid market for
  their shares.  In the judgment of the Board, the Merger should result in
  significant cost savings, enhance the services offered to customers of BMS's
  banking subsidiaries, benefit the communities in which those banks operate,
  and at the same time provide BMS shareholders with the potential of increased
  long-term value.

       Norwest

       Norwest's Board of Directors believes that its acquisition of BMS will
  significantly strengthen Norwest's existing presence in Montana by expanding
  its network of bank subsidiaries into a number of Montana communities in which
  it does not have a bank subsidiary as well as expanding its services in
  communities that already have Norwest bank subsidiaries.  The Merger will
  approximately double Norwest's presence in Montana and permit it to lower
  costs by combining certain operations and data processing, trust services, and
  other business components for its existing bank subsidiaries with those of
  BMS's bank subsidiaries acquired as a result of the Merger.

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

  OPINION OF BMS FINANCIAL ADVISOR

       BMS retained D.A. Davidson to render its opinion as to the fairness, from
  a financial point of view, of the consideration to be received by BMS's common
  shareholders in the Merger.  D.A. Davidson has delivered to the BMS Board of
  Directors its written opinions that, based upon and subject to the various
  considerations set forth in the opinions, as of September 13, 1993 and the
  date of this Proxy Statement-Prospectus, the Exchange Ratio was fair from a
  financial point of view to BMS's shareholders.  No limitations were imposed by
  the BMS Board of Directors upon D.A. Davidson with respect to the
  investigations made or procedures followed by them in rendering their
  opinions.

       The full text of the opinion of D.A. Davidson dated as of the date of
  this Proxy Statement-Prospectus, which sets forth assumptions made, matters
  considered, and limitations on the review undertaken, is attached as Appendix
  C to this Proxy Statement-Prospectus.  BMS shareholders are urged to read this
  opinion in its entirety.  D.A. Davidson's opinion is directed only to the
  Exchange Ratio and does not constitute a recommendation to any BMS shareholder
  as to how such shareholder should vote at the Special Meeting.  The discussion
  of the opinion of D.A. Davidson set forth in this Proxy 

                                       26
<PAGE>


  Statement-Prospectus is qualified in its entirety by reference to the full
  text of such opinion. The September 13, 1993 opinion is substantially
  identical to the opinion attached hereto.

       In arriving at its opinion, D.A. Davidson (i) analyzed certain publicly
  available financial statements and other information of BMS, (ii) analyzed
  certain internal financial statements and other financial and operating data
  concerning BMS prepared by the management of BMS, (iii) reviewed and
  considered the composition and geographical diversity of BMS's branch banking
  operations, (iv) analyzed certain financial projections prepared by the
  management of BMS, (v) discussed the past and current operations and financial
  condition and the prospects, including asset quality trends, of BMS with
  senior executives of BMS, (vi) reviewed the reported prices and trading
  activity for BMS Common Shares, (vii) analyzed certain publicly available
  financial statements and other information of Norwest, (viii) reviewed the
  reported prices and trading activity for Norwest Common Stock, (ix) compared
  the financial performance of BMS  with the financial performance of certain
  other comparable bank holding companies, (x) reviewed the financial terms, to
  the extent available, of certain comparable acquisition transactions, (xi)
  discussed the strategic alternatives to the Merger with BMS, (xii) reviewed
  the Merger Agreement and certain related documents, and (xiii) performed such
  other analyses as it deemed appropriate.

       D.A. Davidson assumed and relied upon, without independent verification,
  the accuracy and completeness of the information reviewed by it for purposes
  of rendering its opinion.  With respect to the financial projections, D.A.
  Davidson assumed that they were reasonably prepared on bases reflecting the
  best currently available estimates and judgments of the future financial
  performance of BMS.  D.A. Davidson also assumed, without independent
  verification, that BMS and Norwest have adequately reserved against losses
  which may be incurred as a result of nonperforming or defaulting loans.  D.A.
  Davidson did not make any independent valuation or appraisal of the assets or
  liabilities of BMS or Norwest, nor was D.A. Davidson furnished with any such
  appraisals, and D.A. Davidson did not examine any individual loan credit
  files.  D.A. Davidson's opinions were based on economic, market and other
  conditions as in effect on, and the information made available to it as of,
  the respective dates of the opinions.

       As part of its financial analysis, D.A. Davidson evaluated (i) the
  possible valuations of BMS on a stand-alone basis, (ii) the implied valuation
  of BMS as a public company and (iii) the acquisition value of BMS based upon
  specific assumptions.  In addition, D.A. Davidson considered premiums paid in
  comparable national and in-market transactions.  The following is a brief
  summary of the written and verbal report presented by D.A. Davidson to the BMS
  Board of Directors on September 7, 1993 (the "D.A. Davidson Report") in
  connection with its September 13, 1993 opinion:

       Summary of Proposal

       D.A. Davidson described the key financial terms of the proposed
  transaction as reflected in the proposed Merger Agreement, including the
  Exchange Ratio.  D.A. Davidson reviewed the implied value of the 4,200,000
  shares of Norwest Common Stock offered as consideration in the Merger.  D.A.
  Davidson noted that under the proposed terms of the Merger, BMS was allowed
  the option to terminate the Merger if the 

                                       27
<PAGE>


  average closing price of Norwest's Common Stock during the 20 trading days
  preceding closing was less than $23.50.  D.A. Davidson also noted that if the
  market price of Norwest Common Stock at closing equaled $23.50, the market
  value of the Norwest Common Stock exchanged in the Merger would be
  approximately $98.7 million, or $48.98 per share.  D.A. Davidson noted that
  the market price of Norwest Common Stock on the date of its analysis was
  $27.375 per share.

       Capitalization of Current Earnings Analysis

       D.A. Davidson applied a capitalization of current earnings analysis as
  one of several methodologies in assessing the going concern value of BMS.
  Using this method, the known or estimated amount of net income of a company is
  capitalized at what is considered to be an appropriate rate of return on the
  investment, the result being the investment value of the company based upon
  current earnings results or expectations.  Based on D.A. Davidson's evaluation
  of market factors and the character and risk of an investment in BMS, D.A.
  Davidson derived a capitalization rate of 11.9%.  D.A. Davidson then applied
  the derived capitalization rate to BMS management's estimate of earnings for
  the twelve months ending June 30, 1994 to derive an estimated value using the
  capitalization of current earnings analysis of approximately $71.4 million, or
  $35.45 per share.  D.A. Davidson noted, however, that the capitalization of
  current earnings method may tend to understate the value of a company as it
  fails to adequately account for reasonably anticipated growth of earnings in
  future years.

       Dividend Paying Capacity Analysis

       Another methodology applied by D.A. Davidson in assessing the going
  concern value of BMS was the dividend paying capacity analysis.  Using this
  analysis, the value of a company is derived by applying the dividend payout
  ratio (i.e., the ratio of dividends paid to net income) and dividend yield
  (i.e., the annual dividends paid per share of common stock to the market price
  per share) of comparable public companies to the earnings of the subject
  company.  As such, the dividend paying capacity of the company is emphasized
  rather than the actual history of dividends paid.  D.A. Davidson established
  an average dividend payout ratio for publicly traded banks during the first
  half of 1993 of 30.8% and an average dividend yield of 3.1% (in each case
  based upon data published by the First Boston Corporation as derived from a
  base of 35 bank holding companies).  By applying these figures to BMS
  management's estimate of earnings for the twelve months ending June 30, 1994,
  D.A. Davidson imputed a value for BMS using the dividend paying capacity
  analysis of approximately $84.5 million, or $41.94 per share.

       Discounted Dividend Stream Analysis

       Using a discounted dividend stream analysis, D.A. Davidson estimated the
  present value of the future streams of after tax cash flows that BMS could
  produce through 1998 and distribute to shareholders ("dividendable net
  income").  In this analysis, D.A. Davidson assumed that BMS performed in
  accordance with the earnings forecasts provided to D.A. Davidson by BMS's
  management and that BMS could pay out up to 100% of its adjusted net income.
  D.A. Davidson estimated the terminal value for BMS common stock at 9.5 times
  BMS's 1998 estimated net income (consistent with estimated historic earnings
  multiples in the banking industry of 9 to 10 times earnings).  The

                                       28
<PAGE>


  dividendable net income streams and terminal value were then discounted to
  present values using a discount rate of 13.9%, chosen to reflect D.A.
  Davidson's assessment of a reasonably expected rate of return to holders or
  prospective buyers of BMS Common Shares in consideration of market factors,
  the character and risk of an investment in BMS and the uncertainty inherent in
  future earnings projections.  This discounted dividend stream analysis
  indicated a value for BMS of approximately $93.3 million or $46.30 per share.
  This analysis was based upon BMS management's projections.  Management's
  projections are based upon many factors and assumptions, many of which are
  beyond the control of BMS.  Consequently, this analysis is not necessarily
  indicative of actual values or actual future results.

       Comparison of Selected Public Companies

       D.A. Davidson assessed the market value of BMS by applying several
  generally recognized valuation criteria for comparable publicly held companies
  to the financial condition and expected operating results of BMS.  The
  valuation multiples used by D.A. Davidson in its analysis were derived from a
  group of 35 bank holding companies as of June 1993.  The valuation criteria
  used were price to book, price to tangible book and price to estimated 1993
  earnings.  D.A. Davidson noted that the average price to book ratio of the
  subject companies was 1.60x, the price to tangible book ratio was 1.68x and
  the price to estimated 1993 earnings ratio was 9.90x.  In applying these
  valuation multiples to BMS, D.A. Davidson derived market values for BMS of
  approximately $86.9 million (or $43.13 per share), $74.9 million (or $37.17
  per share) and $84.1 million (or $41.74 per share), respectively.  D.A.
  Davidson also examined the market valuation multiples for five regional bank
  holding companies which D.A. Davidson determined to be generally comparable to
  BMS and which operated in the Northern Rockies/Upper Midwest region (the "Peer
  Group").  The Peer Group included West One Bancorp, First Security
  Corporation, Community First Bankshares, Zions Bancorporation and First Bank
  System.  D.A. Davidson noted that the average price to book ratio for the Peer
  Group was 1.71x and the average price to estimated 1993 earnings for the Peer
  Group was 10.82x.  In applying the price to book and price to 1993 earnings
  multiples to BMS, D.A. Davidson derived values for BMS of approximately $92.9
  million (or $46.10 per share) and $92.0 million (or $45.66 per share),
  respectively.  In calculating the above ratios, the book values for the
  selected companies were derived from the most recent financial reports of the
  companies; 1993 earnings estimates for the companies were the mean earnings
  estimates for the companies, as published by the Institutional Brokers
  Estimate Service.

       Analysis of Selected Bank Merger Transactions

       D.A. Davidson reviewed the pricing multiples paid in recently-announced
  bank merger or acquisition transactions as a basis for comparison of the
  financial terms offered BMS in the Merger.  D.A. Davidson noted that according
  to data compiled by the First Boston Corporation from SNL Securities, 57 bank
  merger or acquisition transactions were announced during the quarter ended
  June 30, 1993 (including both private and public companies).  The reported
  average valuation multiples involved with these transactions were:  a price to
  book ratio of 1.65x; a price to tangible book ratio of 1.71x; a price to
  trailing twelve months earnings ratio of 16.30x; a price to average assets
  ratio of 13.0%; a price to average deposits ratio of 15.1%; and a premium to
  core deposits ratio of 5.18%.  This analysis yielded an average implied value
  for BMS based upon a broad compilation of 

                                       29
<PAGE>


  recent bank merger and acquisition transactions of approximately $99.3
  million, or $49.28 per share.

       In addition to its analysis of pricing multiples paid in announced bank
  merger or acquisition transactions generally, D.A. Davidson also examined four
  merger transactions involving public bank holding companies in the western
  U.S. announced since June 30, 1992.  Those merger transactions included First
  Bank System's acquisition of Colorado National Bancshares, KeyCorp's
  acquisition of Puget Sound Bancorp, Washington Federal Savings's acquisition
  of First Federal Savings Bank of Utah and West One Bancorp's acquisition of
  Ben Franklin State Bank.  D.A. Davidson noted that the average price to book
  multiple for these transactions was approximately 1.82x and the average price
  to earnings multiple was approximately 14.30x, resulting in an implied value
  for BMS (with equal weightings to each valuation criterion) of approximately
  $101.3 million, or $50.25 per share.

       Finally, D.A. Davidson examined three bank acquisition transactions
  occurring within the state of Montana since 1992, including BMS's acquisition
  of Montana Bancsystem, Inc., Charles Celania, et al.'s acquisition of First
  Security Bank of Havre and Glacier Bancorporation's acquisition of Evergreen
  Bancorporation.  D.A. Davidson noted that the average price to book multiple
  paid in these transactions was approximately 1.26x and the average price to
  earnings multiple was approximately 8.63x, resulting in an implied valuation
  for BMS (with equal weightings to each valuation criterion) of approximately
  $70.9 million, or $35.19 per share.  D.A. Davidson noted, however, that BMS
  shareholders should reasonably expect higher valuation multiples than those
  attracted in other recent Montana transactions due to BMS's expansive banking
  franchise in Montana, BMS's strong financial performance and the passage of
  limited interstate banking in Montana effective October 1, 1993.

       No company or transaction used in any of the above analyses as a
  comparison is identical to BMS or the contemplated transaction.  Accordingly,
  an analysis of the results of the foregoing necessarily involves complex
  considerations and judgments concerning differences in characteristics of the
  companies and the transactions to which comparisons are made.  Mathematical
  analysis is not, in itself, a determinative method of establishing comparable
  value, particularly when applied to isolated or a limited number of
  transactions or companies.

       In connection with its opinion dated as of the date of this Proxy
  Statement-Prospectus, D.A. Davidson confirmed the appropriateness of its
  reliance on the analyses used to render its September 13, 1993 opinion by
  performing procedures to update certain of such analyses and by reviewing the
  assumptions upon which such analyses were based and the factors considered in
  connection therewith.  The foregoing summary does not purport to be a complete
  description of the analyses performed by D.A. Davidson.  D.A. Davidson
  believes that its analyses and the summary set forth above must be considered
  as a whole and that selected portions of its analyses, without considering all
  factors and analyses, could create an incomplete view of the process
  underlying its opinion.  In addition, D.A. Davidson 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 D.A. Davidson's view of the actual value of

                                       30
<PAGE>


  BMS.  In performing its analyses, D.A. Davidson made numerous assumptions with
  respect to industry performance, general business and economic conditions and
  other matters, many of which are beyond the control of BMS or Norwest.  The
  analyses performed by D.A. Davidson 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 D.A. Davidson's overall analysis of the fairness of the Exchange
  Ratio to BMS's shareholders and were provided to the BMS Board in connection
  with the delivery of D.A. Davidson's opinion.  The analyses do not purport to
  be appraisals or to reflect the prices at which a company might actually be
  sold. In addition, as described above, D.A. Davidson's opinion and
  presentation to the BMS Board was one of the many factors taken into
  consideration by the BMS Board in making its determination to approve the
  Merger Agreement and related transactions.  Consequently, the D.A. Davidson
  analyses described above should not be viewed as determinative of the BMS
  Board's or BMS management's opinion with respect to the value of BMS or of
  whether the BMS Board or BMS management would have been willing to agree to a
  different Exchange Ratio.

       The BMS Board of Directors retained D.A. Davidson based upon its
  experience, expertise and familiarity with BMS.  D.A. Davidson is a recognized
  regional investment banking and advisory firm in certain portions of the
  northwest United States.  D.A. Davidson, as part of its investment business,
  is engaged in the valuation of businesses and securities in connection with
  investment research, mergers and acquisitions, negotiated underwritings,
  private placements and valuations for corporate and other purposes.  From time
  to time, D. A. Davidson and its affiliates have provided certain financial
  advisory and financing services to BMS and have received customary fees for
  the rendering of these services.

       Pursuant to a letter agreement dated July 14, 1993 between BMS and D.A.
  Davidson, BMS paid D.A. Davidson a fee upon delivery of its opinion in the
  amount of $50,000.  The letter agreement with D.A. Davidson also provides that
  BMS will reimburse D.A. Davidson for its reasonable out-of-pocket expenses and
  will indemnify D.A. Davidson against certain liabilities, including
  liabilities under securities laws, incurred in connection with its services.

  TERMS OF THE MERGER

       At the Effective Time of the Merger, a wholly owned subsidiary of Norwest
  incorporated in Montana solely for the purpose of consummating the Merger
  ("Merger Co.") will merge into BMS, with BMS as the surviving corporation.  At
  the Effective Time of the Merger, each outstanding share of BMS Common Stock
  will be converted into a number of shares of Norwest Common Stock (the
  "Exchange Ratio") determined by dividing the "Adjusted Norwest Shares" (as
  defined below) by the number of shares of BMS Common Stock then outstanding.
  The "Adjusted Norwest Shares" shall mean 4,200,000 minus (i) $385,000, divided
  by the Norwest Measurement Price (to account for certain severance and bonus
  agreement payments); (ii) the number of shares of BMS Common Stock purchased
  as required by the ESOP from June 22, 1993 through the Effective Date of the
  Merger, multiplied by the Adjusted Norwest Shares after the adjustments in
  clauses (i), (iii), (iv), and (v) have been made, divided by 2,014,676; (iii)
  the amount BMS owes to Norwest for providing, as an independent contractor,
  assistance 

                                       31
<PAGE>


  with the operations, data processing and internal audit functions at BMS,
  divided by the Norwest Measurement Price; (iv) any "Losses" (as defined below)
  that Norwest reasonably determines exist as of 30 days prior to the Effective
  Date of the Merger and (without duplication) any Losses that have been charged
  off in the financial statements of BMS from June 30, 1993 to the Effective
  Time of the Merger, divided by the Norwest Measurement Price; and (v) with
  respect to certain environmental remediation costs, the lesser of the "Net
  Cost" (as defined below) and $100,000, divided by the Norwest Measurement
  Price.  For a further discussion of the events that result in a reduction to
  the Adjusted Norwest Shares and hence to the Exchange Ratio, see "Conditions
  to the Merger," "Business Pending the Merger," and "Interests of Certain
  Persons in the Merger; Certain Transactions."

       "Losses" is defined in the Merger Agreement as those amounts that the
  general ledger balancing and account reconciliation process identifies as (i)
  reconciling items that do not represent valid timing differences and with
  respect to which 45 days have elapsed since the date of origination of the
  related individual general ledger account entries, or (ii) out of balance
  conditions including situations in which the entries in the general ledger and
  the subsidiary ledgers do not correspond or situations in which entries or
  balances in the general ledger or the subsidiary ledgers are not supported by
  valid original source documents or by certifiable systems applications
  balances.

       "Net Cost" is defined in the Merger Agreement as the amount equal to (i)
  the aggregate costs for certain environmental remediation and for the
  development and implementation of certain environmental remediation plans, but
  not for certain environmental assessments, actually paid by BMS prior to the
  Effective Date of the Merger plus the estimated costs contemplated to be paid
  by BMS pursuant to any such environmental remediation plan, but which have not
  been paid as of the Effective Date of the Merger, minus (ii) the aggregate
  amount received by BMS prior to the Effective Date of the Merger from any
  third party that may be obligated to reimburse BMS for such costs (including
  the State of Montana).

       The reductions to the Adjusted Norwest Shares and hence to the Exchange
  Ratio can not be determined at this time and will not be determinable until
  immediately prior to the Effective Time of the Merger.  The reduction to the
  Adjusted Norwest Shares with respect to the employment and severance
  agreements will be based on $385,000; however, this and all of the other
  reductions to the Adjusted Norwest Shares are based, directly or indirectly in
  the case of the reduction with respect to the purchase of shares by the BMS
  ESOP, on the Norwest Measurement Price which cannot be determined at this
  time.  While there have been no purchases of shares by the BMS ESOP from June
  22, 1993 to the date of this Proxy Statement-Prospectus, there can be no
  assurances that such purchases will not occur between the date of this Proxy
  Statement-Prospectus and the Effective Date of the Merger.  As of the date of
  this Proxy Statement-Prospectus, Norwest continues to provide assistance with
  the operations, data processing and internal audit functions and, therefore,
  the amount owed to Norwest for such services is not determinable at this time.
  Although no Losses have been charged off in the financial statements of BMS
  since June 30, 1993, there can be no assurances that Losses will not be
  charged off between the date of this Proxy Statement-Prospectus and the
  Effective Time of the Merger or that other Losses will not be determined by
  Norwest in its reasonable judgment to exist as of 30 days prior to the
  Effective Date of the Merger.  With respect to any reduction to the Adjusted
  Norwest 

                                       32
<PAGE>


  Shares in connection with environmental remediation or environmental
  remediation plans, the "Net Cost" can not be determined at this time and
  although no more than $100,000 is to be used to calculate the reduction to the
  Adjusted Norwest Shares, in the event that the Net Cost exceeds $100,000,
  Norwest is not obligated to close unless BMS agrees to calculate the reduction
  to the Adjusted Norwest Shares based on the full Net Cost including the amount
  of Net Cost that exceeds $100,000.  See "Conditions to the Merger."

       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 several months, and the Norwest
  Measurement Price will fluctuate accordingly.  As a result, the market value
  of the Norwest Common Stock that BMS shareholders ultimately receive in the
  Merger could be more or less than its market value on the date of this Proxy
  Statement-Prospectus.  Because the Exchange Ratio is fixed except for the
  reductions specified above, BMS shareholders will not be compensated for
  decreases in the market price of Norwest Common Stock which could occur before
  the Effective Time of the Merger.  See "Waiver, Amendment, and Termination"
  for a discussion of BMS's right to terminate the Merger Agreement if the
  Norwest Measurement Price is below $23.50.

      The following illustration of the Exchange Ratio is based on the
  provisions of the Merger Agreement and the following assumptions:  that the
  Effective Date of the Merger was December 31, 1993, on which date the Norwest
  Measurement Price would have been $23.86; that no shares of BMS Common Stock
  were purchased by the ESOP from June 22, 1993 to December 31, 1993; that BMS
  owed Norwest $118,900 for providing assistance with the operations, data
  processing and internal audit functions at BMS; that $90,000 of Losses existed
  as of December 31, 1993, and that no Losses were charged off in the financial
  statements from June 30, 1993 to December 31, 1993; that the Net Cost of
  certain environmental remediation and environmental remediation plans was
  $10,000; and that the number of shares of BMS Common Stock outstanding on
  December 31, 1993 was 2,014,676.  Based on the foregoing assumptions, the
  Adjusted Norwest Shares would have been 4,174,690 and the Exchange Ratio would
  have been 2.072.

      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,
  or readjustment, or if a stock dividend thereon is declared with a record date
  within the same period, the conversion ratios 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 BMS 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 BMS shareholder would
  otherwise be entitled multiplied by the average of the closing prices of a
  share of Norwest Common Stock as reported by the consolidated tape of the NYSE
  for each of the five trading days immediately preceding the Effective Time of
  the Merger.

       Each share of capital stock of Merger Co. outstanding immediately prior
  to the Effective Time of the Merger will be converted into shares of BMS
  Common Stock.

                                       33
<PAGE>


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

  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 an executed Agreement and Plan of
  Merger and Articles of Merger are filed with the Secretary of State of the
  State of Montana and at the time of 11:59 p.m., Minneapolis, Minnesota time.
  Such filing shall be made no later than 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 agree, but not prior to February 6,
  1994.  Norwest and BMS also agreed to use their best efforts to cause the
  Merger to be completed within ten business days after the satisfaction or
  waiver of the conditions of the Merger Agreement that the Merger Agreement be
  approved by the requisite vote of the shareholders of BMS, that all necessary
  regulatory approvals, including the approval of the Federal Reserve Board, be
  received, that all applicable waiting and approval periods have expired, and
  that no such approvals contain any conditions that are unduly burdensome to
  Norwest.  Norwest and BMS anticipate that the closing will occur as soon as
  possible following 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 BMS Common Stock a form of letter of transmittal, together with
  instructions for the exchange of such holder's BMS Common Stock certificates
  for a certificate representing Norwest Common Stock.

      BMS SHAREHOLDERS 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 BMS
  Common Stock, together with a properly completed letter of transmittal, there
  will be issued and mailed to the holder a certificate representing the number
  of whole shares of Norwest Common Stock to which such holder is entitled and,
  where applicable, a check for the amount representing any fractional share.  A
  certificate for Norwest Common Stock may be issued in a name other than the
  name in which the surrendered certificate is registered only if (i) the
  certificate surrendered is properly endorsed and otherwise in proper form for
  transfer and (ii) the person requesting the issuance of such certificate
  either pays to the Exchange Agent any transfer or other taxes required by
  reason of the issuance of a certificate for such shares in a name other than
  the registered holder of the certificate surrendered or establishes to the
  satisfaction of the Exchange Agent that such tax has been paid or is not
  applicable.

                                       34
<PAGE>


      All Norwest Common Stock issued pursuant to the Merger will be deemed
  issued as of the Effective Time of the Merger.  No dividends with a record
  date after the Effective Time of the Merger will be paid to BMS shareholders
  entitled to receive certificates for shares of Norwest Common Stock until such
  shareholders surrender their certificates representing shares of BMS 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 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 shareholders of BMS.  In addition, the Merger will occur
  only if all necessary regulatory approvals, including the approval of the
  Federal Reserve Board, are received, and all conditions contained therein are
  met, all applicable waiting and approval periods have expired, and the
  approvals contain no condition or requirement relating to BMS or any of its
  subsidiaries that is unduly burdensome to Norwest; provided that a condition
  of the Federal Reserve Board approval that Norwest sell one or more of (i) the
  Bank of Montana branch in Lewistown, Montana, (ii) the Bank of Montana branch
  in Anaconda, Montana and (iii) one, but not both, of the Montana Bank and Bank
  of Montana branches in Butte, Montana shall not in and of itself be deemed
  unduly burdensome provided the terms and conditions of such sales are
  acceptable to Norwest in its sole discretion.  Norwest has committed to the
  Federal Reserve Board to sell such branches and, therefore, such sale will be
  a condition to the Federal Reserve Board approval, and, hence, a condition to
  the closing.  See "Regulatory Approvals."

      Consummation of the Merger is subject to the satisfaction of certain other
  conditions, unless waived in writing, to the extent waiver is permitted by
  applicable law.  Such conditions to the obligations of both parties to
  consummate the Merger include, but are not limited to, (i) the continued
  effectiveness under the Securities Act of the Registration Statement of which
  this Proxy Statement-Prospectus is a part and receipt by Norwest of all state
  securities law or blue sky authorizations necessary for the Merger, (ii) the
  absence of any order of a court or governmental authority of competent
  jurisdiction restraining, enjoining, or otherwise prohibiting consummation of
  the Merger, (iii) the continued accuracy of the representations and warranties
  by the other party in the Merger Agreement, (iv) the performance by the other
  party of its obligations under the Merger Agreement, (v) the receipt of
  certain officers' certificates from the other party, and (vi) the receipt by
  each party of a letter (the "Comfort Letters") from KPMG Peat Marwick with
  respect to the financial statements and certain other information contained in
  the Proxy Statement-Prospectus about the other party.  Norwest and BMS have
  waived the condition that the Comfort Letters be delivered on the condition
  that each party deliver to the other a letter dated as of the date of this 
  Proxy Statement-Prospectus and updated through the Effective Date of the
  Merger stating that:  (a) the interim quarterly financial statements of such
  party included or incorporated by reference in the Registration Statement are
  prepared in accordance with

                                       35
<PAGE>


  generally accepted accounting principles applied on a basis consistent with
  the audited financial statements of such party; (b) the amounts reported in
  the interim financial statements of such party agree with its
  general ledger; (c) the annual and interim financial statements of such
  party and its subsidiaries included in, or incorporated by reference in, the
  Registration Statement comply as to form in all material respects with the
  applicable accounting requirements of the Securities Act; (d) from September 
  30, 1993 to a specified date not more than 5 days prior to the date of the
  letters, there have been no increases in long-term debt, changes in the
  capital stock or decreases in stockholders' equity of such party and its
  subsidiaries, except for changes, increases or decreases which the
  Registration Statement discloses have occurred or may occur or which are
  described in such letters and for the same period, there have been no
  decreases in consolidated net interest income, consolidated net interest
  income after provision for credit losses, consolidated income before income
  taxes, consolidated net income and net income per share amounts of such party
  and its subsidiaries, or income before equity in undistributed income of
  subsidiaries in each case as compared with the comparable period of the
  preceding year, except in each case for changes, increases or decreases which
  the Registration Statement discloses have occurred or may occur or which are
  described in such letters; and (e) such  party has reviewed certain amounts,
  percentages, numbers of shares and financial information that are derived from
  the general accounting records of such party and its subsidiaries that appear
  in the Registration Statement under certain captions to be specified by the
  other party, and have compared certain of such amounts, percentages, numbers
  and financial information with the accounting records of such party and its
  subsidiaries and have found them to be in agreement with financial records and
  analyses prepared by such party included in the annual and quarterly financial
  statements, except as disclosed in such letters.

      BMS's obligation to consummate the Merger is also subject to (i)
  authorization for listing on the NYSE and CHX upon official notice of issuance
  of the shares of Norwest Common Stock issuable pursuant to the Merger and (ii)
  the receipt of an opinion of its counsel to the effect that, for federal
  income tax purposes the Merger will be a tax-free reorganization (see "Certain
  Federal Income Tax Consequences" for a discussion of such opinion and the
  assumptions on which it will be based).

      Norwest's obligation to consummate the Merger is also subject to (i) the
  receipt by BMS and its subsidiaries of any and all material consents or
  waivers from third parties to loan agreements, leases, or other material
  contracts required for the consummation of the Merger, and the receipt by BMS
  and its subsidiaries of any and all material permits, authorizations,
  consents, waivers, and approvals required for the consummation of the Merger;
  (ii) the requirement that BMS and its subsidiaries shall have taken no action
  since June 22, 1993 that would disqualify the Merger as a pooling of interests
  for accounting purposes (other than actions required under the Merger
  Agreement or requested by Norwest, if any); (iii) the total number of shares
  of BMS Common Stock outstanding and subject to issuance upon exercise of all
  warrants, options, conversion rights, phantom shares, or other share
  equivalents not having exceeded 2,014,676; (iv) the requirement that BMS and
  its subsidiaries considered as a whole shall not have sustained since June 30,
  1993 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) subject to certain specified exceptions, 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 BMS or any of its subsidiaries of, any liability arising under

                                       36
<PAGE>


  any violation of or obligation 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 BMS and its
  subsidiaries taken as a whole; (vi) the completion, prior to the Effective
  Date of the Merger, of certain environmental remediation or, if such
  remediation is not practicable prior to such time using due diligence, then
  the development and implementation of environmental remediation plans
  acceptable to Norwest, provided that if the Net Cost of such remediation and
  remediation plans exceeds $100,000, Norwest shall not be obligated to close
  the Merger unless BMS elects to reduce the Exchange Ratio by taking into
  account the full amount of the Net Cost (including the amount by which the Net
  Cost exceeds $100,000) although Norwest has the right to waive such
  requirement in which event BMS would be obligated to close and the amount by
  which the Net Cost exceeds $100,000 will not be taken into account in
  determining the reduction to the Exchange Ratio (see "Terms of the Merger");
  (vii) the receipt by Norwest of written reports containing the conclusions of
  Phase I and Phase II environmental assessments and studies of the properties
  of BMS and its subsidiaries; (viii) the absence of any change or circumstances
  which might reasonably be expected to have a material adverse effect on the
  financial condition, results of operations, business, or prospects of BMS and
  its subsidiaries taken as a whole, other than changes in banking laws or
  regulations, changes in generally accepted accounting principles or
  interpretations thereof that affect the banking industry generally or changes
  in general economic conditions that uniformly affect the banking industry on a
  nationwide basis, including changes in the general level of interest rates;
  (ix) the delivery of certain representation letters by BMS's executive
  officers, directors and "affiliates," as such term is used in Rule 145 under
  the Securities Act (see "Resale of Norwest Common Stock"); (x) the requirement
  that BMS provide Norwest with the net tax basis and the supporting
  calculations for its properties and the stock in its subsidiaries; (xi) the
  termination or assignment of certain management agreements, leases, life
  insurance policies and related death benefit agreements and correspondent
  service and correspondent master data processing contracts (see "Interests of
  Certain Persons in the Merger; Certain Transactions"); (xii) the delivery at
  the closing of the Merger of the stock certificates for all of the capital
  stock in BMS's subsidiaries (except for certain shares of common stock of
  Montana Bank not owned by MBI) which shall be owned by BMS free and clear of
  liens (see "Interests of Certain Persons in the Merger; Certain Transactions"
  for a discussion of liens in favor of Norwest on the capital stock of BMS's
  subsidiaries); and (xiii) the requirement that the operations and data
  processing functions of BMS and its subsidiaries be operating in a manner
  satisfactory to Norwest.  See "Terms of the Merger," "Business Pending the
  Merger," and "Interests of Certain Persons in the Merger; Certain
  Transactions" for a discussion of the agreement of Norwest to assist with
  BMS's operations and data processing.

  REGULATORY APPROVALS

      The Merger is subject to the prior approval of the Federal Reserve Board
  under Sections 3 and 4 of 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.  The BHC Act prohibits the Federal
  Reserve Board from approving the Merger if it would result in a monopoly or be
  in furtherance of any combination or conspiracy to monopolize or to attempt to
  monopolize the business of banking in any part of the United States, or if its
  effect in any section of the country may be substantially to lessen
  competition or to tend 

                                       37
<PAGE>


  to create a monopoly, or if it would in any other manner be a restraint of
  trade, unless the Federal Reserve Board finds that the anticompetitive effects
  of the Merger are clearly outweighed in the public interest by the probable
  effect of the transaction in meeting the convenience and needs of the
  communities to be served.  The Federal Reserve Board also has the authority to
  deny an application if it concludes that the combined organization would have
  an inadequate capital position.

      Under the BHC Act, the Merger may not be consummated until the 30th day
  following the date of the Federal Reserve Board approval, during which time
  the United States Department of Justice may challenge the Merger on antitrust
  grounds.  The commencement of an antitrust action would stay the effectiveness
  of the Federal Reserve Board's approval unless a court specifically orders
  otherwise.  The BHC Act provides for the publication of notice and public
  comment on the applications and authorizes the regulatory agency to permit
  interested parties to intervene in the proceedings.

      Norwest filed applications with the Federal Reserve Board for approval of
  the Merger on November 2, 1993.  There can be no assurance that the Federal
  Reserve Board will approve the Merger, and if the Merger is approved, there
  can be no assurance as to the date of such approvals or as to what conditions,
  if any, may be imposed in such approvals.

      The Merger Agreement provides, among other conditions, that Norwest's
  obligation to consummate the Merger is conditioned upon no approval, license
  or consent granted by any regulatory authority in connection with the Merger
  containing any condition or requirement relating to BMS or its subsidiaries
  that is unduly burdensome to Norwest, provided that a condition of the Federal
  Reserve Board approval that Norwest sell one or more of (a) the Bank of
  Montana branch in Lewistown, Montana, (b) the Bank of Montana branch in
  Anaconda, Montana and (c) one, but not both of, the Montana  Bank and Bank of
  Montana branches in Butte, Montana shall not in and of itself be deemed unduly
  burdensome provided the terms and conditions of such sales are acceptable to
  Norwest in its sole discretion.  As a result of an analysis of the probable
  competitive effects of the Merger, including conversations with the staff of
  the Federal Reserve System, in the application to the Federal Reserve Board,
  Norwest committed to sell the Bank of Montana branches in Lewistown, Montana
  and Anaconda, Montana and the Montana Bank branch in Butte, Montana to
  competitively suitable acquirors.  Norwest committed itself to execute
  agreements for the sale of such branches prior to the Effective Date of the
  Merger and to consummate such sales within 180 days after the Effective Date
  of the Merger.  Therefore, it will be a condition of any Federal Reserve Board
  approval that Norwest comply with these commitments.  BMS has agreed to
  cooperate with Norwest in the sale of these branches.  There can be no
  assurances that Norwest will be able to execute an agreement to sell such
  branches prior to the Effective Date of the Merger on terms and conditions
  acceptable to it or that Norwest will be able to consummate such sales within
  180 days after the Effective Date of the Merger.  If Norwest does not
  consummate such sales within such 180-day period, it has committed itself in
  its application to the Federal Reserve Board, to transfer the three branches
  to an independent trustee with full discretion to sell them to a purchaser
  acceptable to the Federal Reserve System without regard to price.  There also
  can be no assurance that the Federal Reserve Board will not impose other
  conditions which may be unduly burdensome to Norwest.  See "Conditions to the
  Merger," "Business Pending the Merger," and "Management and Operations After
  the Merger."

                                       38
<PAGE>


      There likewise can be no assurance that the Department of Justice will not
  challenge the Merger or, if such a challenge is made, what the result would
  be.  Any approval of the application merely implies satisfaction of regulatory
  criteria for approval, which do not include review of the transaction from the
  standpoint of the adequacy of the consideration to be received by, or fairness
  to, shareholders.

      Effective October 1, 1993, the Montana Bank Act, Sections 32-1-101 et
  seq., Montana Code Annotated, was amended to permit a bank holding company
  that does not have its headquarters in Montana and that either has its
  headquarters in Colorado, Idaho, Minnesota, North Dakota, South Dakota,
  Wisconsin, and Wyoming or that controlled a bank in Montana on January 1, 1993
  to acquire control of a bank located in Montana under the following
  circumstances:  if the laws of such Reciprocal States authorized a Montana
  bank holding company to acquire a bank in such Reciprocal States under terms
  and conditions substantially similar to the terms and conditions imposed by
  Montana law; and if the bank to be acquired has been conducting business
  continuously for at least six years prior to the acquisition.  Montana law
  requires that a bank holding company seeking to acquire a bank located in
  Montana file with the Montana Department of Commerce a copy of the
  applications submitted to the federal banking regulatory agency and a
  statement verifying that the bank holding company will not control more than
  18% of all deposits in federally insured banks, savings associations and
  credit unions in Montana and that all bank holding companies headquartered
  outside of Montana will not control more than 49% of all deposits in federally
  insured banks and savings associations in Montana.  The Montana law provides
  for the publication of notice and public comment on the applications and
  authorizes the Montana Department of Commerce to intervene in or take other
  action in the federal banking regulatory authority proceedings.  See
  "Background of and Reasons for the Merger" and "INFORMATION ABOUT BMS--
  Business--Supervision and Regulation."

      Norwest filed copies of the Federal Reserve Board applications and the
  statements required by Montana law with the Montana Department of Commerce on
  November 3, 1993 and believes that the Montana and Minnesota laws authorizing
  limited interstate banking are substantially similar.  There can be no
  assurance, however, that the Montana Department of Commerce will not intervene
  or take other action with respect to the Merger or, if such intervention or
  action were taken, what its result would be.

      Norwest and BMS 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 or as to what conditions,
  if any, may be imposed in such approvals.  The Merger cannot proceed in the
  absence of all requisite regulatory approvals.  See "Conditions to the
  Merger," "Effective Time of the Merger," and "Waiver, Amendment, and
  Termination."

  BUSINESS PENDING THE MERGER

       Under the Merger Agreement, BMS and each of its subsidiaries are
  generally obligated to maintain their corporate existence in good standing; to
  maintain the general character of their business and conduct their business in
  its ordinary and usual manner;  to maintain proper business and accounting
  records in accordance with reasonable business practices; to maintain their
  properties in good repair and condition, ordinary wear and tear excepted; to
  maintain in all material respects presently existing insurance coverage; to
  use their best efforts to preserve their business organization intact, to keep
  the services of their present principal employees and to preserve their good
  will and the good will of their suppliers, customers and others having
  business relationships with them; to use their best efforts to obtain any
  approvals or consents required to maintain existing leases and other contracts
  in effect following the Merger; to comply in all material respects with all
  laws, regulations, ordinances, codes, orders, licenses and permits applicable
  to the properties and operations of BMS and each of its subsidiaries
  (including, without limitation, the Americans With Disabilities Act), the non-
  compliance with which reasonably could be expected to have a material adverse
  effect on BMS and its subsidiaries taken as a whole; and to permit Norwest and
  its representatives (including KPMG Peat Marwick) to examine the books,
  records and properties, and to interview the officers, employees and agents,
  of BMS and its subsidiaries at any time during normal business hours, provided
  however that no such examination by Norwest or its representatives either
  before or after the date of the Merger Agreement shall in any way affect,
  diminish or terminate any of the representations, warranties or covenants of
  BMS set forth in the Merger Agreement.

       The Merger Agreement also provides that, prior to the Effective Time of
  the Merger, neither BMS nor any of its subsidiaries will (without the prior
  written consent of Norwest) amend or otherwise change its articles of
  incorporation or by-laws; issue or sell or authorize for issuance or sale, or
  grant any options or make other agreements with respect to the issuance or
  sale or conversion of, any shares of its capital stock, phantom shares or
  other share-equivalents, or any other of its securities; authorize or incur
  any long-term debt (other than deposit liabilities); mortgage, pledge or
  subject to lien or other encumbrance any of its properties, except in the
  ordinary course of business; enter into any material agreement, contract or
  commitment in excess of $25,000, except banking transactions in the ordinary
  course of business and in accordance with policies and procedures in effect on
  the date of the Merger Agreement; make any investments, except investments
  made by BMS subsidiaries in the ordinary course of business for terms of up to
  two years and in amounts of $1,000,000 or less; except for the termination of
  MBI's ESOP and the merger of the 401(k) plans of MBI and BMS and except as
  requested by Norwest, amend or terminate any "employee benefit plan" (as
  defined in the Employee Retirement Income Security Act of 1974, as amended),
  except as required by law; make any contributions to any such plan except as
  required by the terms of such plan in effect as of the date of the Merger
  Agreement; redeem, purchase or otherwise acquire, directly or indirectly, any
  of the capital stock of BMS, except pursuant to and as required by the ESOP
  (see "Terms of the Merger"); increase the compensation of any officers,
  directors or executive employees, except pursuant to existing compensation
  plans and practices and except that BMS and its subsidiaries may enter into
  severance and bonus agreements with certain specified employees (see
  "Interests of Certain Persons in the Merger; Certain Transactions" for a
  description of such agreements, and see "Terms of the Merger" for their effect
  on the Exchange Ratio); sell or otherwise dispose of any shares of the capital

                                       40
<PAGE>


  stock of any BMS subsidiary; or sell or otherwise dispose of any of its assets
  or properties other than in the ordinary course of business.

       Furthermore, the Merger Agreement provides that neither BMS nor any of
  its subsidiaries will (without prior consultation with Norwest) make any new
  loan or modify, restructure or renew any existing loan (except pursuant to
  commitments made prior to the date of the Merger Agreement) 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 $500,000, no more
  than $100,000 of which shall be unsecured loans or extensions of credit.

      Neither BMS nor any of its subsidiaries, nor any director, officer,
  representative or agent thereof, will, directly or indirectly, solicit,
  authorize the solicitation of, or enter into any discussions with or execute
  any agreement in principle or definitive agreement with any corporation,
  partnership, person, or other entity or group (other than Norwest or its
  representatives) concerning, any offer or possible offer (i) to purchase any
  shares of common stock, any option or warrant to purchase any shares of common
  stock, any securities convertible into any shares of such common stock, or any
  other equity security of BMS or any of its subsidiaries; (ii) to make a tender
  or exchange offer for any shares of BMS Common Stock or other equity security;
  (iii) to purchase, lease, or otherwise acquire the assets of BMS or any of its
  subsidiaries, except in the ordinary course of business; or (iv) to merge,
  consolidate, or otherwise combine with BMS or any of its subsidiaries.  Any
  offer or inquiry to BMS or any of its subsidiaries concerning any of the
  foregoing must be promptly disclosed, along with the terms thereof, to
  Norwest.

      BMS also agreed in the Merger Agreement that neither BMS nor its
  subsidiaries will take any action (other than actions required under the
  Merger Agreement or requested by Norwest, if any) that would disqualify the
  Merger as a pooling of interests for accounting purposes and that BMS would
  establish such additional accruals and reserves that are necessary to conform
  to the accounting and credit loss reserve practices and methods of Norwest and
  to reflect Norwest's plans with respect to the conduct of BMS's business
  following the Merger and to provide for certain costs and expenses relating to
  the Merger.

      BMS has also agreed not to consummate the planned merger of Montana Bank
  into Bank of Montana, but to use its best efforts to obtain extensions from
  the appropriate regulatory authorities to permit consummation of the Merger of
  the bank subsidiaries at some future date.  As of December 13, 1993, the
  Federal Reserve Board had extended until March 18, 1994 its approval of the
  consummation of such merger.

      The Merger Agreement also provided that BMS would take certain actions
  with respect to its planned acquisition of Heritage.  Subsequent to the
  execution of the Merger Agreement, BMS assigned its rights to acquire
  Heritage.  Norwest consented to the assignment and waived compliance by BMS
  with the provisions of the Merger Agreement that related to Heritage or to the
  proposed Heritage acquisition.  See "Conditions to the Merger" and "Interests
  of Certain Persons in the Merger; Certain Transactions."

      BMS also agreed in the Merger Agreement to cooperate with Norwest in the
  sale of the Bank of Montana branches in Lewistown, Montana and Anaconda,
  Montana and one, but not both, of the Bank of Montana and Montana Bank
  branches in Butte, Montana to the 

                                       41
<PAGE>


  extent such branches must be sold (see "Conditions to the Merger" and
  "Regulatory Approvals") and in the sale of the business of escrowing title
  under contracts for deed or bank contracts and the related services in which
  BMS and its subsidiaries are engaged (the "Escrow Business").  Such
  cooperation may include legally effecting such sales immediately prior to the
  Effective Time of the Merger and permitting potential purchasers to examine
  the books, records and properties of and to interview officers, employees and
  agents of BMS and its subsidiaries at any time during normal business hours. 
  BMS also agreed to use its best efforts to sell the insurance business
  conducted under the name "Roundup Agency."  Such sale was consummated on
  November 1, 1993.

      BMS has also agreed to pay in full all indebtedness of BMS to Norwest
  Bank, immediately prior to the Effective Time of the Merger.  Norwest
  Corporation has agreed in the Merger Agreement to loan BMS, immediately prior
  to the Effective Time of the Merger, sufficient funds to enable BMS to pay
  such indebtedness in full.  See "Interests of Certain Persons in the Merger;
  Certain Transactions" for a description of such indebtedness.  It is a
  condition to the closing that such indebtedness be paid and that BMS deliver
  the stock it owns in its subsidiaries to Norwest free and clear of all liens.
  See "Conditions to the Merger."

      In the Merger Agreement, Norwest and BMS agreed that BMS would retain
  Norwest as an independent contractor to provide assistance with the
  operations, data processing and internal audit functions of BMS.  The Exchange
  Ratio will be reduced based on the amount that Norwest will be compensated.
  See "Terms of the Merger" and "Interests of Certain Persons in the Merger;
  Certain Transactions."  It is a condition to the Merger that the operations
  and data processing functions be operating in a manner satisfactory to
  Norwest.  See "Conditions to the Merger."

      BMS also agreed in the Merger Agreement to complete certain environmental
  remediation at the Montana Bank branch sites in Roundup, Montana and Big
  Sandy, Montana and the Heritage site in Great Falls, Montana or if it is not
  practicable to complete such remediation using due diligence prior to the
  Effective Date of the Merger, to develop and implement, prior to the Effective
  Date of the Merger, a comprehensive plan acceptable to Norwest to complete
  such environmental remediation.  In no event shall BMS be required to incur
  cost in excess of $100,000 for conducting such remediation or implementing
  such remediation plans, provided that if the Net Cost of such remediation and
  remediation plans exceeds $100,000, Norwest shall not be obligated to close
  unless BMS elects to reduce the Exchange Ratio by taking into account the full
  amount of the Net Cost (including the amount by which the Net Cost exceeds
  $100,000) although Norwest has the right to waive such requirement in which
  event BMS would be obligated to close and the amount by which the Net Cost
  exceeds $100,000 would not be taken into account in determining the reduction
  to the Exchange Ratio.  See "Terms of the Merger" for a further discussion of
  the effect of the Net Cost on the Exchange Ratio.  See also "Conditions to the
  Merger."  BMS has assigned its rights to acquire Heritage and Norwest
  consented to the assignment and waived compliance with this covenant as it
  relates to Heritage.  See "Interests of Certain Persons in the Merger; Certain
  Transactions" for a further discussion of BMS's assignment of its rights to
  acquire Heritage.

      BMS has agreed that prior to the Effective Time of the Merger it will not
  declare, set aside, make or pay any dividend or other distribution with
  respect to its capital stock 

                                       42
<PAGE>


  except that it may pay regular quarterly cash dividends not exceeding $0.42
  per share each quarter and except that if the Effective Date of the Merger
  occurs on or before the record date for Norwest Common Stock for a particular
  quarterly dividend period, BMS may pay a cash dividend equal to $846,164,
  minus the dividend paid on 4,200,000 shares of Norwest Common Stock the
  preceding quarter, prorated for the number of days in such dividend period
  that precede the Effective  Date of the Merger, divided by the number of
  outstanding shares of BMS Common Stock.  For example, the record date for the
  Norwest Common Stock dividend for the fourth quarter was November 5, 1993, the
  dividend on Norwest Common Stock for such quarter was $0.165 per share, BMS
  paid its third quarter dividend on August 26, 1993, and the number of
  outstanding shares of BMS Common Stock on November 1, 1993 was 2,014,676.  If
  the Effective Date of the Merger had been on November 1, 1993, BMS would have
  been permitted, under the terms of the Merger Agreement, to declare a dividend
  of $.06 per share for the fourth quarter.  Any of the BMS Subsidiaries may
  declare and pay any regular dividend in accordance with applicable law.

  WAIVER, AMENDMENT, AND TERMINATION

      Either Norwest or BMS may, in writing, 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 the
  BMS shareholders may adversely affect the consideration to be received by the
  BMS 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 April 15, 1994, unless such failure of consummation is due to
  the failure of the party seeking termination to perform or observe in all
  material respects the covenants and agreements to be performed or observed by
  it under the 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 BMS by written notice to Norwest given no later than 5:00 p.m. Minneapolis
  time on the first business day immediately preceding the scheduled Closing
  Date in the event that the Norwest Measurement Price is less than $23.50 per
  share.  Certain provisions of the Merger Agreement relating to (a) the duty of
  each party to preserve the confidentiality of certain information of the other
  party, (b) Norwest's duty to indemnify and hold BMS harmless for losses caused
  by Norwest in connection with Norwest's environmental investigation of BMS,
  and (c) expenses incurred in connection with the Merger Agreement, will
  survive the termination of the Merger Agreement pursuant to the above
  described termination provisions.

  MANAGEMENT AND OPERATIONS AFTER THE MERGER

      After the Merger, BMS will become a direct subsidiary of Norwest.  Bank of
  Montana and Montana Bank will remain wholly owned subsidiaries of BMS and will
  become indirect subsidiaries of Norwest.  Norwest will operate at the present
  locations of Bank of Montana and Montana Bank  providing products and services
  offered by Norwest affiliates.  In its application to the Federal Reserve
  Board, Norwest has committed itself to consummate the sale of the Bank of
  Montana branches in Lewistown, Montana and Anaconda, Montana and the Montana
  Bank branch in Butte, Montana to competitively suitable acquirors within 180
  days after the Effective Date of the Merger.  See "Regulatory Approvals" for a
  further discussion of such sales.  In addition, Norwest also intends to sell
  the Escrow Business.  See "Business Pending the Merger" for a further
  discussion of such sale.

  INTERESTS OF CERTAIN PERSONS IN THE MERGER; CERTAIN TRANSACTIONS

       The Board of Directors of BMS was aware of the agreements, transactions
  and interests of certain persons in the Merger described below and considered
  them, among other matters, in recommending approval of the Merger and the
  transactions contemplated thereby.

       Under the Merger Agreement, Norwest, for three years following the
  Effective Time of the Merger, must maintain directors' and officers' liability
  insurance in favor of BMS's directors and officers with respect to future
  claims arising from facts or events that occurred before the Effective Time of
  the Merger.  Such insurance must contain terms and conditions no less
  favorable than the policies currently maintained by BMS in favor of its
  directors and officers.  Norwest must also insure that all rights to
  indemnification and all limitations of liability existing in favor of any
  director, officer, employee, fiduciary or agent of BMS or its subsidiaries in
  BMS's Articles of Incorporation and Bylaws or similar governing documents of
  any subsidiary of BMS, as in effect on the date of the Merger Agreement, or
  allowed under applicable law as in effect on such date, with respect to claims
  arising from facts or events that occurred before the Effective Time of the
  Merger, shall survive the Merger and shall continue in full force and effect,
  without amendment, for a period of not less than three years from the
  Effective Time of the Merger.

       Under the Merger Agreement, BMS must terminate the Service Agreement,
  between BMS and Central Financial Services, Inc. ("Central Financial"),
  pursuant to which Central Financial provides management, accounting and data
  processing services to BMS and a Sublease Agreement between BMS and Central
  Financial pertaining to the lease of office facilities in Golden Valley,
  Minnesota.  John Morrison, an officer and director of BMS, owns all of the
  capital stock of Central Financial and Michael Pint, also an officer and
  director of BMS, is President and a director of Central Financial.  In
  addition, pursuant to the Merger Agreement, BMS must terminate all key man and
  split dollar life insurance policies and related death benefit agreements.
  Edward C. Lamb, a director and Executive Vice President of BMS, is a
  beneficiary of a key man life insurance policy.  Mr. Morrison and Mr. Pint are
  beneficiaries of split dollar life insurance policies.  The termination of the
  Service Agreement, the Sublease Agreement and the insurance policies  is to be
  effective no later than the Effective Date of the Merger and is to be effected
  without payment of any consideration, penalty or other amount with respect to
  such 

                                       44

  termination by BMS or its subsidiaries.  BMS has also agreed to use its best
  efforts to cancel all correspondent service contracts and correspondent master
  data processing contracts between BMS Computer Corporation, a subsidiary of
  BMS, and all entities other than Bank of Montana and Montana Bank at the
  lowest possible cost, which costs must be approved in advance by Norwest. 
  Central Bank of Stillwater, Minnesota ("Central Bank") and First National Bank
  of Barron in Barron, Wisconsin ("Barron") have such contracts. Mr. Morrison
  owns 100% of Central Bank and Mr. Pint is a director of Central Bank and
  Barron.

       Under that certain Combination Stock Purchase Agreement and Agreement and
  Plan of Merger, dated as of July 1, 1993 (the "Heritage Acquisition
  Agreement"), by and among BMS, Bank of Montana, John Buchanan and Sheila
  Buchanan (the "Buchanans") and Heritage, BMS, subject to the satisfaction of
  certain conditions in the Heritage Acquisition Agreement, was obligated to
  acquire the outstanding Common Stock of Heritage held by the Buchanans and to
  consummate certain other transactions contemplated by the Heritage Acquisition
  Agreement.   On _____, 1993, BMS executed an Assignment and Assumption
  Agreement whereby BMS assigned its rights under the Heritage Acquisition
  Agreement to a corporation ("Heritage Acquisition Corporation") of which
  Barbara Forster, an officer and director of BMS, is the sole shareholder (the
  "Assignment").  The Assignment has been structured so that the consummation of
  any business combination between Heritage Acquisition Corporation and Heritage
  will not be effected prior to the Effective Date of the Merger and BMS will
  retain its right to acquire Heritage on the same terms and conditions
  currently in place under the Heritage Acquisition Agreement  in the event that
  the Merger is not consummated.  On November 10, 1993, Norwest consented to the
  Assignment and waived compliance by BMS with certain provisions of the Merger
  Agreement with respect to Heritage and the Heritage Acquisition Agreement.
  The Assignment will not affect the Exchange Ratio.

       BMS is currently indebted to Norwest Bank in the principal amount of
  $18.3 million pursuant to a Note, dated March 31, 1993, executed by BMS in
  favor of Norwest Bank.  The outstanding principal on the Note is payable in
  increasing installments of principal through December 31, 2001.  Interest on
  the Note is payable quarterly at an annual rate of interest equal to Norwest
  Bank's "base" or "prime" lending rate.  Approximately $8,516,000 of the
  proceeds of the Note were used by BMS to pay a portion of the purchase price
  in connection with BMS's acquisition of MBI.  See "INFORMATION ABOUT BMS--
  Business--Recent Developments" for a discussion of the acquisition of MBI.
  The balance of the proceeds of the Note was used to refinance existing
  indebtedness to Norwest Bank incurred primarily in connection with other bank
  acquisitions by BMS.  Repayment of the Note is secured by all of the capital
  stock of the subsidiary banks.  Certain of Norwest's affiliates and BMS have
  also entered into additional agreements relating to correspondent-bank
  practices such as:  demand deposit accounts, brokerage and safekeeping
  arrangements, a revolving line of credit, repurchase agreements, secured and
  unsecured "Fed Funds" lines and other non-lending account and customer
  relationships.  These agreements have all been established on substantially
  the same terms as those generally established from time to time by Norwest
  banking or brokerage affiliates for comparable account and customer
  relationships with their business, correspondent banking or brokerage
  customers.  Under the terms of the Merger Agreement, prior to the Effective
  Time of the Merger, Norwest will make a loan to BMS to enable BMS to pay in
  full its indebtedness to Norwest Bank.

                                       45
<PAGE>


       John Morrison is currently indebted to Norwest Bank in the principal
  amount of $16.8 million pursuant to two Notes (the "Morrison Notes") dated
  March 31, 1993 and April 20, 1993, each executed by Mr. Morrison in favor of
  Norwest Bank.  The outstanding principal on the Morrison Notes is payable in
  increasing installments of principal through March 2003.  The proceeds of the
  Morrison Notes were used by Mr. Morrison to finance his purchases of BMS
  Common Stock from time to time, including in connection with the financing of
  the acquisition of MBI by BMS, and for other business purposes.  See
  "INFORMATION ABOUT BMS--Business--Recent Developments."  The Morrison Notes
  are secured by substantially all of the BMS Common Stock held by Mr. Morrison
  and Mr. Pint and certain shares held by Ms. Forster.  Mr. Morrison is also
  indebted to Norwest Bank pursuant to a commercial real estate mortgage loan in
  the principal amount of $210,100 which is due in November of 1994 and carries
  an interest rate of 4.35%.  Michael Pint is currently indebted to Norwest 
  Bank  in the principal amount of $750,000 pursuant to a Demand Note (the "Pint
  Note") dated November 24, 1993, executed by Mr. Pint in favor of Norwest 
  Bank. The proceeds of the Pint Note were used by Mr. Pint to acquire his BMS
  Common Stock from time to time from 1989 to 1991 and for other business
  purposes.  The Pint Note is also secured by substantially all of the BMS
  Common Stock held by Mr Morrison and Mr. Pint and certain shares held by Ms.
  Forster.  One of the Morrison Notes and the Pint Note accrue interest on the
  outstanding principal at an annual rate at or above Norwest Bank's "base" or
  "prime" lending rate and contain substantially the same terms as those
  generally established from time to time by Norwest Bank for comparable lending
  relationships.  The other Morrison Note carries an interest rate of 2% over
  the federal funds rate.

       The Merger Agreement permits BMS to enter into severance and bonus
  agreements with certain specified employees including Steven Feurt, a director
  of BMS prior to March 31, 1992, and Edward Lamb, currently a director of BMS.
  Such agreements may provide that, for a period of one year from the Effective
  Date of the Merger, in the event that Norwest terminates such person's
  employment other than for cause, such person will receive a severance payment
  equal to the  number of weeks from but excluding the date of termination
  through the date that is one year from the Effective Date of the Merger
  divided by 52 and then multiplied by such person's current annual salary.  See
  "Terms of the Merger" for a discussion of the related reduction in the
  Exchange Ratio.

       Under the Merger Agreement, BMS has agreed to retain Norwest as an
  independent contractor to provide assistance to BMS in the operations, data
  processing  and internal audit functions including integrating such functions
  at Bank of Montana with such functions at Montana Bank.  BMS has entered into
  an agreement with Norwest whereby Norwest is providing such services for an
  amount equal to the salary, cost of benefits and out of pocket expenses for
  each employee of Norwest who performs any such services.  The Exchange Ratio
  will be reduced based on the amount that Norwest will be compensated.  See
  "Terms of the Merger."  If the Merger is not consummated, the agreement
  automatically terminates.  It is a condition to the Merger that the operations
  and data processing functions be operating in a manner satisfactory to
  Norwest.  See "Conditions to the Merger."

       On July 25, 1992, Norwest entered into an Agreement and Plan of
  Reorganization with Rocky Mountain Bankshares, Inc. ("RMBI") pursuant to which
  a wholly owned subsidiary of Norwest was merged into RMBI (the "RMBI
  Merger").  The RMBI Merger 

                                       46
<PAGE>


  was consummated on January 8, 1993.  RMBI was a bank holding company that
  owned The Bank of Aspen, a bank chartered under the laws of the state of
  Colorado.  John M. Morrison owned 24.5% of the outstanding common stock of
  RMBI.  W. Duncan MacMillan owned 33.0% of the outstanding common stock of
  RMBI.  Michael J. Pint owned 9.5% of the outstanding common stock of RMBI. 
  Messrs. Morrison, Pint, and MacMillan each received Norwest Common Stock in
  exchange for their shares of RMBI Common Stock pursuant to the RMBI Merger.

  CERTAIN DIFFERENCES IN RIGHTS OF SHAREHOLDERS

       The rights of BMS shareholders are governed by the Restated Articles of
  Incorporation of BMS, as amended (the "BMS Articles"), the Bylaws of BMS (the
  "BMS Bylaws") and the laws of the State of Montana.  The rights of Norwest
  stockholders are governed by the Restated Certificate of Incorporation of
  Norwest, as amended (the "Norwest Certificate"), the By-Laws of Norwest (the
  "Norwest By-Laws") and the laws of the State of Delaware.  After the Merger
  becomes effective, the rights of BMS shareholders who become Norwest
  stockholders will be governed by the Norwest Certificate, the Norwest By-Laws
  and the laws of the State of Delaware.  In certain respects, rights of BMS
  shareholders and Norwest stockholders are similar.  While it is not practical
  to describe all changes in the rights of BMS shareholders that will result
  from the application of Delaware law in lieu of Montana law and the
  differences between the BMS Articles and Bylaws and the Norwest Certificate
  and Bylaws, the following is a summary of certain significant differences.

       Capital Stock

       The BMS Articles authorize the issuance of 4,000,000 shares of capital
  stock, par value $2.50 per share, and do not authorize the issuance of
  preferred stock.  BMS currently has outstanding only one class of capital
  stock.  Accordingly, all BMS shareholders have equal rights and preferences
  with respect to dividends and distributions upon liquidation.  The Norwest
  Certificate authorizes the issuance of 500,000,000 shares of common stock, par
  value $1-2/3 per share (the "Norwest Common Stock"), of which 290,770,768
  shares were outstanding and 2,328,700 were held as treasury shares at
  September 30, 1993, and 5,000,000 shares of preferred stock (the "Norwest
  Preferred Stock") of which 2,276,500 shares were outstanding at September 30,
  1993, and 1,000,000 shares are reserved for issuance upon the exercise of
  certain rights described below.

       Norwest has authorized for issuance from time to time and registered with
  the Commission an additional 1,700,000 shares of Norwest Preferred Stock.
  Norwest has also authorized for issuance from time to time and registered with
  the Commission pursuant to a universal shelf registration statement, an
  indeterminate number of securities (the "Shelf Securities") with an aggregate
  initial offering price not to exceed $1,000,000,000.  The Shelf Securities may
  be issued as Preferred Stock or as securities convertible into shares of
  Preferred Stock or Common Stock.  Based on the current number of shares of
  Preferred Stock authorized for issuance under Norwest's Certificate of
  Incorporation, the maximum number of shares of Preferred Stock and Common
  Stock, respectively, that could be issued pursuant to effective shelf
  registration statements, when added to shares of Preferred Stock and Common
  Stock already reserved for issuance, issued, or outstanding, could not exceed

                                       47
<PAGE>


  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 Norwest Preferred Stock
  or Shelf Securities issuable as, or convertible into, Norwest Preferred Stock
  may be issued by the Board of Directors of Norwest without further action by
  Norwest stockholders.  Holders of Norwest Preferred Stock have certain rights
  and preferences with respect to dividends and upon liquidation that are
  superior to those of holders of Norwest Common Stock.  The relative rights and
  preferences of any Norwest Preferred Stock issued in the future may be
  established by the Norwest Board of Directors without stockholder action.
  Although management has no current plans for the issuance of any shares of
  Norwest Preferred Stock, except as disclosed in this Proxy Statement-
  Prospectus, such shares of Norwest Preferred Stock, when and if issued, could
  have dividend, liquidation, voting, and other rights superior to those of
  Norwest Common Stock.

       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.

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

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

                                       48
<PAGE>


            (i)  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.

            (ii)  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.

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

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

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

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

       Election of Directors

       All holders of BMS Common Stock have the right of cumulative voting, that
  is, the right to vote the number of shares held, multiplied by the number of
  directors to be 

                                       49
<PAGE>


  elected, and to cast such votes for one director or distribute such votes
  among as many nominees as desired.  Stockholders of Norwest do not have the
  right of cumulative voting, but instead are entitled to one vote for each
  share of capital stock held.  Under Delaware law, directors are elected by a
  plurality of votes.

       Required Vote for Authorization of Certain Actions

       The Montana Business Corporation Act (the "MBCA") generally requires the
  affirmative vote of the holders of two-thirds of the outstanding shares of
  each class entitled to vote to approve a merger, consolidation, share
  exchange, or sale, lease, exchange, or other disposition of all or
  substantially all of a corporation's property not made in the regular course
  of business.  In certain circumstances, the holders of outstanding shares of a
  class of capital stock of a Montana corporation are entitled to vote as a
  separate voting group, regardless of whether the articles of incorporation
  provide that such shares of capital stock are entitled to vote.  However, no
  vote of shareholders of a Montana corporation is required to approve a merger
  if (i) that corporation is the surviving corporation of the merger, (ii) the
  related plan of merger does not amend the corporation's articles of
  incorporation in a manner that would require a shareholder vote, (iii) each
  shareholder of the surviving corporation whose shares are outstanding
  immediately before the merger will hold the same number of shares, with
  identical designations, preferences, limitations, and relative rights,
  immediately after the merger, and (iv) the number of voting shares or shares
  entitled to participate without limitation in distributions of the corporation
  to be issued in the merger, or to be issuable upon conversion of any
  convertible instruments to be issued in the merger, does not exceed 20% of the
  voting shares or participating shares, as the case may be, of that corporation
  outstanding immediately before the merger.

        Under Delaware law, the vote of a simple majority of the outstanding
  shares of Norwest Common Stock entitled to vote thereon is required to approve
  a merger or consolidation, or the sale, lease, or exchange of substantially
  all of Norwest's corporate assets.  With respect to a merger, no vote of the
  stockholders of Norwest is required if Norwest is the surviving corporation
  and (i) the related agreement of merger does not amend the Norwest
  Certificate, (ii) each share of stock of Norwest outstanding immediately
  before the merger is an identical outstanding or treasury share of Norwest
  after the merger, and (iii) the number of shares of Norwest stock to be issued
  in the merger (or to be issuable upon conversion of any convertible
  instruments to be issued in the merger) does not exceed 20% of the shares of
  Norwest Common Stock outstanding immediately before the merger.

       Amendment of Corporation Charter

       Under the MBCA, the Board of Directors can establish conditions for the
  amendment of the Articles of Incorporation (e.g., super-majority vote, no more
  than a given percentage dissent, etc.).  The Board of Directors is required to
  make a recommendation on the desirability of any amendment (unless a conflict
  of interest prohibits them from doing so).  The MBCA provides that certain
  significant amendments to articles of incorporation, but not all amendments,
  must be approved by the shareholders.  Pursuant to Section 35-1-227 of the
  MBCA, the vote of shareholders needed to approve an amendment depends in part
  on the voting groups entitled to vote separately on the 

                                       50
<PAGE>


  amendment and in part on whether any of those voting groups would be entitled
  to dissenter's rights if the amendment were adopted.  Generally, if
  dissenter's rights would not arise in connection with the amendment, Section
  35-1-528 of the MBCA provides that if a quorum exists, action on a matter
  other than the election of directors is approved if the votes cast within the
  voting group favoring the action exceed the votes cast opposing the action,
  unless the articles of incorporation or the MBCA require a greater number of
  affirmative votes.  If the amendment would give rise to dissenters' rights
  under the MBCA, the amendment must be approved by the holders of a majority of
  the outstanding shares of each voting group that will have dissenters' rights
  if the amendment were adopted, unless the articles of incorporation, the board
  of directors or the MBCA specifies a greater quorum or voting requirement for
  a voting group to approve an amendment of any type.

       Delaware law requires the vote of a simple majority of the outstanding
  shares of Norwest Common Stock in order to amend the Norwest Certificate.

       Dissenters' Rights

       Under the MBCA, any shareholder of a corporation is entitled to receive
  payment of the fair value of such shareholder's shares of capital stock if
  such shareholder properly dissents from (i) any merger, share exchange or
  consummation of a sale or exchange of all or substantially all of the property
  of the corporation not made in the regular course of business for which a vote
  of such shareholder is required, (ii) any corporate action that results in an
  amendment of the articles of incorporation that materially and adversely
  affects rights with respect to a dissenter's shares because it alters or
  abolishes a preferential right of the shares, creates, alters or abolishes a
  right in respect of redemption, alters or abolishes a preemptive right of the
  holder of the shares, excludes or limits the right of the shares to be voted
  on any matter or to cumulate votes, or reduces the number of shares owned by
  the shareholder to a fraction of a share if the fractional share so created is
  to be acquired for cash, or (iii) any other corporate action taken pursuant to
  a shareholder vote to the extent the articles of incorporation, bylaws or
  resolution of the board of directors provides that voting or nonvoting
  shareholders are entitled to dissent and to obtain payment for their shares.
  See the more detailed discussion below under "Dissenters' Rights."

       Under Delaware law, a stockholder is generally entitled to receive
  payment of the appraised value of such stockholder's shares if the stockholder
  dissents from a merger or consolidation.  However, appraisal rights are not
  available to holders of (i) shares listed on a national securities exchange or
  held of record by more than 2,000 persons or (ii) 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
  (a) shares of stock of the surviving corporation, (b) shares of stock of
  another corporation which are also listed on the national securities exchange
  or held by more than 2,000 holders, or (c) cash in lieu of fractional shares
  of such stock.  Appraisal rights are not available for a sale of assets or an
  amendment to the Norwest Certificate.  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.

                                       51
<PAGE>


       Special Meetings

       Under the MBCA and the BMS Bylaws, a special meeting of BMS shareholders
  may be called by the Chairman, the President or by the Board of Directors, and
  must be called by the President at the request of holders of not less than 10%
  of all outstanding shares of the corporation entitled to vote at the meeting.
  Under Delaware law and the Norwest By-Laws, 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.

       Anti-Takeover Statutes

       Montana does not have an anti-takeover statute.  The Delaware anti-
  takeover 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 (i) the board of directors approved the business combination before the
  stockholder became an interested stockholder, (ii) upon consummation of the
  transaction which resulted in a 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 (iii) 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.

       Dividends and Distributions

       Distributions to shareholders of a Montana corporation, including
  redemptions, repurchases and dividends, may not be made if any such
  distribution would render the corporation unable to meet its liabilities in
  the ordinary course of business or, if as a result of such distribution, the
  excess of the corporation's assets over its liabilities would be less than the
  liquidation preference of all shares having a preference on liquidation over
  the class or series to which the distribution is made.

       A Delaware corporation  may make repurchases or redemptions that do not
  impair capital and may pay dividends out of any surplus account (generally the
  stockholders' equity of the corporation less the par value of the capital
  stock outstanding) or, if there exists no surplus, out of net profits of the
  current and preceding fiscal years (provided that certain provisions must be
  made for preferences of outstanding stock having a liquidation preference).
  Dividends may not be paid out of net profits if, after the payment of the
  dividend, capital is less than the capital represented by the outstanding
  stock of all classes having a preference upon the distribution of assets.

       Norwest and BMS are subject to the same Federal Reserve Board policies
  regarding payment of dividends, which generally limit dividends to operating
  earnings.  See "INFORMATION ABOUT BMS" and "CERTAIN REGULATORY
  CONSIDERATIONS."

       Action Without a Meeting

       Under the MBCA, any action required or permitted to be taken at a
  shareholders' meeting may be taken without a meeting if the action is taken by
  all the shareholders entitled to vote on the action and is evidenced by
  written consents.  Delaware law permits any action required or permitted to be
  taken at a stockholder's meeting to be taken by written consent, signed by the
  holders of a number of shares that would have been required to effect the
  action at an actual meeting of the stockholders at which all shares entitled
  to vote were present and voted.  Generally, holders of a majority of
  outstanding shares can effect such an action.  Delaware law also provides that
  a corporation's certificate of incorporation may restrict or prohibit
  stockholders' action without a meeting.  The Norwest Certificate does not
  restrict or prohibit stockholders' action without a meeting.

       Removal of Directors

       Under the MBCA and the BMS Articles, the shareholders of a Montana
  corporation may remove one or more directors with or without cause.  In
  addition, any director or the entire Board of Directors may be removed only by
  a vote of the holders of two-thirds of the shares entitled to vote at an
  election of directors.  A director may not be removed if the votes cast
  against the removal of such director would be sufficient to elect him if
  cumulatively voted at an election of the entire board of directors.  Under
  Delaware law, any director or the entire Board of Directors of Norwest may be
  removed with or without cause, by the holders of a majority of the shares then
  entitled to vote in an election of directors.

       Limitation of Director Liability and Indemnification in Certain
  Circumstances

       Under the MBCA, a director of a Montana corporation 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 reasonably believes to be in the
  best interests of the corporation.

       The BMS Bylaws generally provide that BMS must indemnify its officers and
  directors made a party to any action, suit, or proceeding, whether civil or
  criminal, from any judgments, penalties, 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 BMS 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 BMS, that his or her
  conduct was in the best interests of BMS; (ii) in all other non-criminal
  cases, that his or her conduct was at least not opposed to BMS'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.

                                       53
<PAGE>


       If the action was by or in the right of BMS (a "derivative action"),
  indemnification is only available for any reasonable expenses incurred.  No
  indemnification is available where the officer or director is adjudged liable
  to BMS or in which the officer or director has been adjudged liable on the
  basis that he or she improperly received a personal benefit.  The board of
  directors of BMS or a court of competent jurisdiction must determine, prior to
  any indemnification, that the director or officer has met the applicable
  standard of conduct set forth in the bylaws.

       Expenses incurred in defending any action may be paid by BMS in advance
  of the final disposition of such action upon receipt of an undertaking by a
  director or officer to repay such amount unless it is ultimately determined
  that he or she is entitled to be indemnified.  The indemnification provided by
  the Bylaws is substantially similar to the indemnification provisions in the
  MBCA.  The MBCA, however, provides that the indemnification provisions in a
  corporation's articles, bylaws, resolutions or contracts are invalid to the
  extent they are inconsistent with the statute.

       Under Delaware law, 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, the Norwest Certificate provides
  that a director (including an officer who is also a director) of Norwest shall
  not be liable personally to Norwest or its stockholders for monetary damages
  for breach of fiduciary duty as a director, except for liability arising out
  of (i) any breach of 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
  Delaware General Corporation Law, 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 the Norwest Certificate 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.

                                       54
<PAGE>


       The Norwest Certificate 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.  The Norwest Certificate also provides
  that Norwest must pay expenses incurred in defending the proceedings specified
  above in advance of their final disposition, provided that if so required by
  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.

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

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

       Shareholder Derivative Proceedings

       Under Delaware and Montana law, before a shareholder may bring an action
  by or on behalf of the corporation (a "derivative action"), a shareholder must
  make a demand on the corporation's Board of Directors to remedy the situation
  about which the shareholder complains.  Under Delaware law, the demand
  requirement may be excused if the shareholder can show that such demand would
  be futile because the alleged wrongdoers comprised or controlled a majority of
  the Board of Directors.  Under the MBCA, the futility exception to the demand
  requirement has been eliminated.  Therefore, a shareholder bringing a
  derivative action on behalf of a Montana corporation will be required in all
  instances to make a demand on the corporation's Board of Directors.

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

  DISSENTERS' RIGHTS

       Any shareholder of BMS may, as an alternative to receiving a
  consideration specified in the Merger Agreement, dissent from the Merger and
  obtain payment of the fair 

                                       55
<PAGE>


  value of such shareholder's BMS Common Stock pursuant to Sections 35-1-826
  through 35-1-839 of the MBCA.  "Fair Value" with respect to a dissenter's
  shares, means the value of the shares immediately before the Effective Time of
  the Merger, excluding any appreciation or depreciation in anticipation of the
  corporate action unless exclusion would be inequitable.  Any BMS shareholder
  contemplating exercising the right to demand such payment should carefully
  review Sections 35-1-826 through 35-1-839 of the MBCA, a copy of which is
  included as Appendix B to this Proxy Statement-Prospectus, and in particular
  the required procedural steps.  A SHAREHOLDER WHO FAILS TO COMPLY WITH THESE
  PROCEDURAL REQUIREMENTS MAY LOSE THE RIGHT TO DISSENT.

       Set forth below, to be read in conjunction with the full text of Sections
  35-1-826 through 35-1-839 of the MBCA, is a summary of the procedures relating
  to the exercise of dissenters' rights.  The following summary does not purport
  to be complete and is qualified in it entirety by reference to Appendix B.  As
  used in the following discussion, "BMS" means BMS before the Effective Time of
  the Merger and Norwest as BMS's successor after the Effective Time of the
  Merger.

       A record shareholder may assert dissenters' rights as to fewer than all
  the shares registered in his name only if such shareholder dissents with
  respect to all shares beneficially owned by any one person and notifies the
  corporation in writing of the name and address of each person on whose behalf
  such shareholder asserts dissenters' rights.  In that event, such
  shareholder's rights shall be determined as if the shares as to which such
  shareholder dissents and such shareholder's other shares were registered in
  the name of different shareholders.  A beneficial shareholder may assert
  dissenters' rights as to shares held on such shareholder's behalf only if such
  shareholder submits to the corporation a written consent by the record holder
  to the dissent not later than the time the beneficial shareholder asserts
  dissenters' rights and such shareholder does so with respect to all shares of
  which the shareholder is the beneficial owner or over which such shareholder
  has power to direct the vote.

       Any BMS shareholder who wishes to dissent must deliver to BMS, prior to
  the vote on the Merger Agreement, a written notice of intent to demand payment
  for such shareholder's shares if the Merger is effectuated.  In addition, the
  shareholder must refrain from voting in favor of the Merger Agreement.  A
  shareholder who fails to deliver the notice on time or who votes in favor of
  the Merger Agreement will not have any dissenters' rights.  If a shareholder
  returns a signed proxy but does not specify a vote against approval of the
  Merger Agreement or a direction to abstain, the proxy will be voted for
  approval of the Merger Agreement, which will have the effect of waiving that
  shareholder's dissenters' rights.

       If the Merger Agreement is approved by the required vote, BMS is required
  to deliver a written dissenters' notice to all shareholders who gave a timely
  notice of intent to demand payment and who did not vote in favor of the Merger
  Agreement.  The notice must be sent no later than 10 days after the Merger
  Agreement is approved and must (i) state where the payment demand must be sent
  and where and when certificates for certificated shares must be deposited,
  (ii) inform shareholders of uncertificated shares to what extent transfer of
  the shares will be restricted after the payment is received, (iii) supply a
  form for demanding payment that includes the date of the first announcement to
  news media or to 

                                       56
<PAGE>


  shareholders of the terms of the proposed corporate action and that requires
  the person asserting dissenters' rights to certify whether or not such
  shareholder acquired beneficial ownership of the shares before that date, (iv)
  set a date by which BMS must receive the payment demand, which may not be
  fewer than 30 nor more than 60 days after the date the required dissenters'
  notice is delivered, and (v) be accompanied by a copy of Sections 35-1-826
  through 35-1-839 of the MBCA.

       A shareholder who is sent the dissenters' notice described above must
  demand payment, certify whether the shareholder acquired beneficial ownership
  of the shares before the date required to be set forth in the dissenters'
  notice, and deposit such shareholder's certificates in accordance with the
  terms of the notice.  A shareholder who does not demand payment or deposit
  certificates where and when required is not entitled to payment for such
  shareholder's shares. A shareholder who demands payment and deposits his
  certificates as requested by the dissenters' notice retains all other rights
  of a shareholder until such rights are canceled by the consummation of the
  Merger.  BMS may restrict the transfer of uncertificated shares from the date
  of the demand for payment until the Merger is consummated; however, the holder
  of uncertificated shares retains all other rights of a shareholder until those
  rights are canceled by the consummation of the Merger.

       Except as provided in the following paragraph, as soon as the Merger is
  effectuated or upon receipt of the payment demand, BMS must pay each dissenter
  who complied with the foregoing requirements the amount BMS estimates to be
  the Fair Value of the dissenters' shares plus accrued interest.  The payment
  must be accompanied by certain financial information concerning BMS, a
  statement of BMS's estimate of the Fair Value of the shares, an explanation of
  how the interest was calculated, a statement of the dissenter's right to
  demand payment if the dissenter is dissatisfied with the payment or offer (as
  further described in the next paragraph), and a copy of Sections 35-1-826
  through 35-1-839 of the MBCA.  If the Merger does not occur within 60 days
  after the date set in the dissenters' notice for demanding payment and
  depositing certificates, BMS must return the deposited certificates and
  release the transfer restrictions imposed on uncertificated shares.
  Notwithstanding the foregoing,  BMS may elect to withhold payment from any
  dissenter with respect to shares of which the dissenter or the person on whose
  behalf the dissenter acts was not the beneficial owner before September 14,
  1993, the date of the first announcement to news media of the terms of the
  Merger.  If BMS elects to withhold such payments, after the consummation of
  the Merger, BMS must estimate the Fair Value of the shares plus accrued
  interest and pay this amount to each dissenter who agrees to accept it in full
  satisfaction of his demand.  BMS must send with its offer a statement of its
  estimate of Fair Value of the shares, an explanation of how interest was
  calculated and a statement of the dissenter's right to demand payment if he is
  dissatisfied with the offer.

       A dissenter may notify BMS in writing of the dissenter's own estimate of
  the Fair Value of the dissenter's shares and the amount of interest due with
  respect thereto and may demand payment of the dissenter's estimate, less any
  previous payment, or reject BMS's offer and demand payment of the Fair Value
  of the dissenter's shares and the interest due if (i) the dissenter believes
  that the amount paid or offered is less than the Fair Value of the dissenter's
  shares or that the interest due is incorrectly calculated, (ii) BMS fails to 
  make payment within 60 days after the date set for demanding payment, or (iii)
  BMS, having failed to effectuate the Merger, does not return the deposited
  certificates or release the transfer restrictions on uncertificated shares
  within 60 days after the date set for demanding 

                                       57
<PAGE>


  payment.  A dissenter waives the right to demand payment unless the dissenter
  notifies the corporation of his demand in writing within 30 days after BMS
  made or offered payment for the dissenter's shares.

       Within 60 days after any such subsequent demand is submitted by a
  shareholder, if such demand remains unsettled, BMS is required to file in an
  appropriate court in Montana, a petition to determine the Fair Value of the
  shares and accrued interest.  If BMS does not commence the proceeding within
  the 60-day period, it is to pay each dissenter whose demand remains unsettled
  the amount demanded.  Each dissenter made a party to the proceeding is
  entitled to judgment for the amount, if any, by which the court finds the Fair
  Value of the dissenter's shares plus interest exceeds the amount paid by BMS
  or for the Fair Value plus accrued interest of his after-acquired shares for
  which BMS elected to withhold payment.  The cost and expenses of any such
  court proceedings will be assessed against BMS except that the court may
  assess any part of those costs as an expense against all or some dissenters
  who are parties to the proceeding and whose action in demanding a payment in
  addition to that offered by BMS the court finds to be arbitrary, vexatious, or
  not in good faith.  The court may also assess the fees and expenses of counsel
  and experts for the respective parties, in amounts the court finds equitable,
  against BMS and in favor of any or all dissenters if the court finds that BMS
  failed to comply substantially with the statutory requirements or against
  either BMS or a dissenter, in favor of any other party, if the court finds
  that the party against whom the fees and expenses are assessed acted
  arbitrarily, vexatiously, or not in good faith.  If the court finds that the
  services of counsel for any dissenter were of substantial benefit to other
  dissenters similarly situated and should not be assessed against BMS, it may
  award to the counsel reasonable fees to be paid out of the amount awarded to
  the dissenters who were benefitted.

       BMS shareholders considering exercising dissenters' rights should bear in
  mind that the Fair Value of their BMS Common Shares determined under Section
  35-1-826 through 35-1-839 could be more than, the same as or less than the
  value of the consideration they will receive pursuant to the Merger Agreement
  if they do not exercise dissenters' rights.

  CERTAIN FEDERAL INCOME TAX CONSEQUENCES

       BMS expects that the Merger will be treated as a tax-free reorganization
  within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Code and
  that for federal income tax purposes no gain or loss will be recognized by any
  shareholder of BMS upon receipt of Norwest Common Stock pursuant to the
  Merger, except upon the receipt of cash in lieu of fractional shares of
  Norwest Common Stock.  The Internal Revenue Service (the "Service") has not
  been and will not be asked to rule upon the tax consequences of the Merger.
  Instead, BMS will rely upon the opinion of Dorsey & Whitney, its special
  outside legal counsel, as to certain federal income tax consequences of the
  Merger to BMS's shareholders.  It is a condition to the consummation of the
  Merger that BMS receive such opinion from Dorsey & Whitney.  The opinion of
  Dorsey & Whitney will be based upon the facts described herein and upon
  certain representations made by BMS, Norwest and certain principal
  shareholders of BMS.  The opinion of Dorsey & Whitney will also be based upon
  the Code, regulations now in effect thereunder, current administrative rulings
  and practice, and judicial authority, all of which are subject to change.  An
  opinion of counsel is not binding on the Service and there can be no

                                       58
<PAGE>


  assurance, and none is hereby given, that the Service will not take a position
  contrary to one or more positions reflected herein or that the opinion will be
  upheld by the courts if challenged by the Service.  EACH HOLDER OF BMS COMMON
  STOCK IS URGED TO CONSULT HIS OR HER OWN TAX AND FINANCIAL ADVISORS AS TO THE
  EFFECT OF SUCH FEDERAL INCOME TAX CONSEQUENCES ON HIS OR HER OWN PARTICULAR
  FACTS AND CIRCUMSTANCES AND ALSO AS TO ANY STATE, LOCAL, FOREIGN OR OTHER TAX
  CONSEQUENCES ARISING OUT OF THE MERGER.

       Based upon the facts and representations provided to it, and subject to
  various assumptions and qualifications, Dorsey & Whitney will opine that the
  following federal income tax consequences to the shareholders of BMS will
  result from the Merger:

            (i)  The Merger will qualify as a reorganization within the meaning
       of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Code;

            (ii)  No gain or loss will be recognized by the holders of BMS
       Common Stock upon the exchange of BMS Common Stock solely for Norwest
       Common Stock pursuant to the Merger (but see clause (v) below for the tax
       consequences of payments in lieu of fractional shares);

            (iii)  The income tax basis of the Norwest Common Stock received by
       a stockholder of BMS pursuant to the Merger, including any fractional
       share interest deemed received as described in (v) below, will be the
       same as the income tax basis of the BMS Common Stock surrendered in
       exchange therefor;

            (iv)  The holding period of the Norwest Common Stock received by a
       shareholder of BMS pursuant to the Merger will include the period during
       which the BMS Common Stock surrendered therefor was held, provided that
       such BMS Common Stock is a capital asset in the hands of the shareholder
       of BMS on the Effective Date of the Merger; and

            (v)  A holder of BMS Common Stock receiving cash in lieu of a
       fractional share of Norwest Common Stock will be treated as having
       received the fractional share of Norwest Common Stock in the Merger and
       then having received the payment in lieu of the fractional share as a
       distribution in full payment in exchange for the fractional share as
       provided in Section 302(a) of the Code.

       The opinion described above will be based upon certain assumptions,
  including the assumption that the shareholders of BMS do not have any plan or
  intention to dispose of more than 50% of the Norwest Common Stock received
  pursuant to the Merger and the assumption that, after the Merger, BMS will
  meet the "substantially all" test defined by the Service which requires, in
  part, that BMS hold assets representing at least 90% of the fair market value
  of the net assets and at least 70% of the fair market value of the gross
  assets held by BMS immediately prior to the Merger.  For purposes of such
  assumptions, the Escrow Business and the Bank of Montana branches in
  Lewistown, Montana and Anaconda, Montana and the Montana Bank branch in Butte,
  Montana that may be disposed of after the Merger, as well as amounts paid by
  BMS to dissenting shareholders and amounts paid for reorganization expenses of
  BMS, will be considered as assets held by BMS immediately prior to the Merger.

                                       59
<PAGE>


       Norwest has represented that (other than the sale of the Escrow Business
  and the sale of such branches) it does not have any current plan or intention
  to take any action within the twelve month period following the Effective Date
  of the Merger that would cause BMS to violate the "substantially all" test.
  Norwest has further covenanted not to take any such action within the twelve-
  month period following the Effective Date of the Merger.  The Merger Agreement
  provides that the BMS shareholders who are holders of record immediately prior
  to the Effective Time of the Merger are third party beneficiaries of the
  foregoing Norwest representation and covenant and are entitled to rely
  thereon.

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

  RESALE OF NORWEST COMMON STOCK

      The shares of Norwest Common Stock issuable to shareholders of BMS 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 BMS or Norwest as that term is defined in the
  rules under the Securities Act.  Norwest Common Stock received by those
  shareholders of BMS who are deemed to be "affiliates" of BMS may be resold
  without registration as provided for by Rule 145, or as otherwise permitted
  under the Securities Act.  In the Merger Agreement, BMS has agreed to use its
  best efforts to cause each BMS shareholder who is an executive officer or
  director of BMS or who may otherwise reasonably be deemed to be an affiliate
  of BMS 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 BMS.  EACH
  SHAREHOLDER WHO MAY BE DEEMED TO BE AN AFFILIATE IS URGED TO CONSULT
  INDEPENDENT LEGAL COUNSEL CONCERNING APPLICABLE RESTRICTIONS ON RESALE.

      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 effective upon official
  notice of issuance.

  EFFECT ON BMS EMPLOYEE BENEFIT PLANS

      Each person who is an employee of BMS or its subsidiaries as of the
  Effective Date of the Merger ("BMS Employees") will be eligible for
  participation in certain employee welfare benefit plans (as set forth in the
  Merger Agreement) and the Norwest Savings-Investment Plan, subject to any
  eligibility requirements (with full credit for years of past service to BMS or
  its subsidiaries, as the case may be, or to any predecessor-in-interest of BMS
  or its subsidiaries to the extent such service is presently given credit under
  the plans of BMS or its subsidiaries, for the purpose of satisfying any
  eligibility and vesting periods) applicable to such plans (but, with respect
  to the employee welfare benefit plans, not subject to any pre-existing
  condition exclusions) and shall enter into such plans not later than the first
  day of the calendar quarter which begins at least 32 days after the Effective
  Date of the Merger.  Each BMS Employee shall be eligible for participation, as
  a new employee, in the Norwest Pension Plan under the terms thereof.

  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 such 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 such 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 BMS who receive Norwest Common Stock in
  the Merger will have the right to participate in such plan.

  ACCOUNTING TREATMENT

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

      Under the pooling of interests method of accounting, the historical basis
  of the assets and liabilities of Norwest and BMS will be combined at the
  Effective Time of the Merger and carried forward at their previously recorded
  amounts, and the shareholders' equity accounts of BMS will be combined with
  Norwest's on Norwest's consolidated balance sheet.  Income and other financial
  statements of Norwest will not be restated retroactively because the Merger is
  not material to the financial statements of Norwest.

      In order for the Merger to qualify for pooling of interests accounting
  treatment, among other things, substantially all (90% or more) of the
  outstanding BMS Common Stock must be exchanged for Norwest Common Stock.  BMS
  has agreed not to take any action (other than actions required under the
  Merger Agreement or requested by Norwest) that would disqualify the Merger
  from pooling of interests treatment by Norwest.

      The unaudited per share data contained in this Proxy Statement-Prospectus
  has been prepared using the pooling of interests accounting method to account
  for the Merger.  See "SUMMARY--Comparative Unaudited Per Share Data."

  EXPENSES

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


                             INFORMATION ABOUT BMS

  BUSINESS

       General

       BMS is a bank holding company registered under the BHC Act and
  headquartered in Great Falls, Montana.  BMS was incorporated as a Montana
  corporation in 1956.  BMS owns all of the outstanding capital stock of Bank of
  Montana, a bank chartered under the laws of Montana with 17 branches in 15
  Montana communities.  On March 31, 1993, BMS acquired all of the outstanding
  capital stock of MBI (see discussion under "Recent Developments" below).  MBI
  is a bank holding company registered under the BHC Act and headquartered in
  Billings, Montana.  MBI in turn owns approximately 99.6% of the outstanding
  capital stock of Montana Bank ("Montana Bank"), a bank chartered under the
  laws of Montana with 12 branches in 12 Montana communities.  BMS also has
  certain other subsidiaries engaged in activities related to banking.  At
  September 30, 1993, BMS had consolidated total assets of $797.0 million and
  total shareholders' equity of $55.2 million.  See the Unaudited Consolidated
  Financial Statements and Notes thereto of BMS contained  in "FINANCIAL
  STATEMENTS."

       BMS derives substantially all of its revenues from cash dividends and
  service fees paid by Bank of Montana and Montana Bank, its bank subsidiaries.
  Dividend payments by subsidiary banks are determined on an individual basis
  considering each bank's earnings, deposit growth and capital requirements.
  Service fees paid by BMS's bank subsidiaries to BMS represent payments for
  services provided to each bank subsidiary by BMS personnel.  It has been BMS's
  practice to increase the capital of each subsidiary primarily through
  retention of earnings.

       Bank of Montana was organized in 1961 and accounts for approximately 57%
  of BMS's consolidated assets.  Montana Bank was organized in 1978 and accounts
  for approximately 42% of BMS's consolidated assets.  Bank of Montana and
  Montana Bank operate exclusively in Montana through 29 branches located in 25
  Montana communities.  BMS's bank subsidiaries serve a wide range of
  commercial, agricultural and consumer borrowing needs within their markets.
  Such banks extend various types of loans, including short- and long-term
  residential and commercial real estate mortgage loans to individuals and
  businesses.  Commercial lending products include lines and letters of credit,
  receivable and inventory financing and equipment financing and leasing.  In
  addition, BMS's bank subsidiaries provide various types of secured and
  unsecured consumer loans, indirect installment loans and second mortgages and
  equity lines.

                                       62
<PAGE>


       BMS's bank subsidiaries provide a full range of deposit products,
  including checking accounts, savings accounts, certificates of deposit and
  money market instruments.  BMS's bank subsidiaries also offer other services,
  including individual retirement accounts, credit card services and annuities.

       Management services are provided to the bank subsidiaries by certain
  other subsidiaries of BMS and by Central Financial in the areas of asset and
  liability management, investment administration and portfolio planning,
  business development, personnel selection and training, advertising and data
  processing.  While the managers of the individual branch banks and the
  officers of the bank subsidiaries are responsible for day-to-day management,
  BMS monitors lending and accounting policies, budgeting goals and long-range
  plans by means of centralized auditing, lending and accounting control
  systems.

       Recent Developments

       The acquisition of MBI in March 1993 represented a significant
  acquisition for BMS and substantially increased BMS's outstanding loans,
  deposits and geographic representation in the state of Montana.  See
  "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION" and "FINANCIAL
  STATEMENTS."  BMS had discussed a possible business combination with MBI prior
  to 1992 but had been unable to agree with MBI on the terms of such a
  combination.  In April 1992, BMS representatives contacted representatives of
  MBI and presented to MBI a proposal to acquire all of the issued and
  outstanding capital stock of MBI. After significant due diligence and
  negotiation, on September 1, 1992, BMS and MBI entered into a definitive
  merger agreement pursuant to which BMS agreed to purchase all of the
  outstanding capital stock of MBI for $19.00 per share for an aggregate
  purchase of approximately $39,000,000.  BMS initially contemplated financing
  the MBI acquisition with the proceeds from (i) the sale of $11.25 million of a
  new class of BMS convertible preferred stock (the "Preferred Stock") to
  Norwest, (ii) the sale of $11.25 million of Preferred Stock to W. Duncan
  MacMillan, (iii) an $8.5 million loan from Norwest Bank (the "Norwest Loan"),
  and (iv) a cash dividend from Montana Bank to MBI of $8,000,000.  The purchase
  agreement for the Preferred Stock  would have given Norwest a limited right of
  first refusal with respect to the sale of BMS and the right to convert the
  Preferred Stock to BMS Common Stock after five years.  The acquisition of MBI
  and the financing of the acquisition were required to be approved by the
  Federal Reserve Board.

       Because of regulatory concerns on the part of the staff of the Federal
  Reserve System regarding the proposed sale of the Preferred Stock to Norwest,
  BMS, Norwest and Mr. MacMillan terminated all agreements with respect to the
  sale of the Preferred Stock and the Preferred Stock was never authorized.  To
  replace the proceeds from the contemplated sale of the Preferred Stock, 
  Messrs. MacMillan, Morrison and Pint purchased newly issued BMS Common Stock. 
  See "THE MERGER--Interests of Certain Persons in the Merger; Certain
  Transactions" for a discussion of the loan from Norwest to Mr. Morrison used 
  to finance such purchases by Mr. Morrison.  The Federal Reserve Board
  subsequently approved the MBI acquisition, including the revised financing
  structure, and the MBI acquisition was consummated on March 31, 1993.

       Market Area and Competition

       BMS competes exclusively in Montana, except for the credit card services
  offered by the bank subsidiaries which are marketed throughout the United
  States.  With the acquisition of MBI in March 1993, BMS became the largest
  Montana-based banking organization doing business in Montana.  BMS now
  operates branch banks in substantially all significant markets in Montana.
  BMS competes with numerous financial institutions in its market areas,
  including commercial banks, savings and loan associations, savings banks,
  mortgage companies, commercial bank loan production offices, insurance
  companies, consumer finance companies, securities brokerage firms, credit
  unions and mutual  funds.

       Properties

       Real property owned or leased by BMS consists primarily of bank buildings
  for Bank of Montana and Montana Bank.  BMS's executive offices, which are
  leased, are located at 410 Central Avenue, Great Falls, Montana.  BMS or its
  banking subsidiaries own all but two of the bank branch locations.  BMS also
  leases space in connection with its data processing center which services the
  bank subsidiaries.

       Employees

       As of September 30, 1993, BMS and its subsidiaries employed 450 people on
  a full-time equivalent basis.  Management considers its relationship with its
  employees to be good.

       Market Price of and Dividends on BMS Common Stock

       There is no established public trading market for BMS Common Stock.  BMS
  is aware of only limited transactions involving the sale of BMS Common Stock
  since the Merger Agreement was executed.  The prices for the BMS Common Stock
  in such transactions should not be considered indicative of prices that could
  be obtained in an active market involving a substantial number of shares.

       There were 210 shareholders of record of BMS Common Stock as of the
  Record Date for the Special Meeting.  BMS has declared a cash dividend in
  every quarter since the second quarter of 1987.  See "SUMMARY--Comparative
  Unaudited Per Share Data."

       Supervision and Regulation

       To the extent the information below consists of summaries of certain
  statutory provisions, it is qualified in its entirety by reference to the
  statutory provisions so described.  For a description of federal regulations
  generally applicable to bank holding companies, see "CERTAIN REGULATORY
  CONSIDERATIONS."

       BMS is subject to the provisions of the BHC Act, which requires a bank
  holding company to register with the Federal Reserve Board and be subject to
  its supervision.  The BHC Act requires prior approval by the Federal Reserve
  Board of the acquisition by a bank holding company of more than 5% of the
  voting stock or substantially all the assets 

                                       64
<PAGE>


  of any bank, but does not require prior approval before acquisition of
  additional shares in banks, the majority of the shares of which are already
  controlled by such bank holding company.  A bank holding company is
  prohibited, with limited exceptions, from acquiring direct or indirect
  ownership or control of more than 5% of the voting shares of any company that
  is not a bank and from engaging in activities other than those of banking or
  of managing or controlling banks and other authorized subsidiaries and
  providing services to its subsidiaries.  One of the exceptions to this
  prohibition permits ownership of the shares of a company, the activities of
  which the Federal Reserve Board determines to be so closely related to the
  business of banking or of managing or controlling banks as to be a proper
  incident thereto.  The Federal Reserve Board has published regulations
  regarding these matters, which, in the opinion of management of BMS, enable
  BMS to engage in its present operations.  In addition, bank holding companies
  are subject to certain restrictions on their ability to own banks in more than
  one state.

       BMS is required to file periodic reports with the Federal Reserve Board
  and such other information as may be required to keep the Federal Reserve
  Board informed regarding BMS's compliance with the provisions of the BHC Act
  and the rules, regulations and orders issued thereunder, and the Federal
  Reserve Board examines BMS and its subsidiary banks periodically.

       Bank of Montana and Montana Bank, as state-chartered banks, are subject
  to the supervision and regulation of, and are regularly examined by, the
  Division of Banking and Financial Institutions of the State of Montana
  Department of Commerce (the "Division") and, as members of the Federal Reserve
  System, are subject to regulation by the Federal Reserve Board.  Bank of
  Montana and Montana Bank are members of the Federal Deposit Insurance
  Corporation.

       As members of the Federal Reserve System, Bank of Montana and Montana
  Bank are limited in their ability to pay dividends to BMS to the same extent
  as a national bank.  Without prior approval, federal law limits the payment of
  dividends by a national bank if (i) such dividends would impair the bank's
  capital, (ii) the bank's surplus is not equal to its common capital, or (iii)
  dividends declared in any year exceed the total of net profits for that year
  combined with retained net profits for the preceding two years, less any
  required transfers to surplus or to a fund for the retirement of preferred
  stock.  Under Montana law, Bank of Montana and Montana Bank may not pay or
  declare dividends in excess of net undivided profits (as defined) less any
  required transfers to surplus and must provide notice to the Division of any
  dividend exceeding two years of net earnings.

       The Federal Reserve Board has broad powers to expand and contract the
  supply of money and credit.  The supply of money and credit is also affected
  by the fiscal practices of the United States government.  These may directly
  or indirectly affect the growth of loans and deposits and the interest rates
  charged on loans and paid for deposits and may affect the operations of Bank
  of Montana and Montana Bank.

       Effective October 1, 1993, the Montana Bank Act, Sections 32-1-101 et
  seq., Montana Code Annotated, was amended by legislation (i) authorizing
  interstate bank acquisitions, subject to certain restrictions, by a bank
  holding company that does not have its headquarters in Montana and either has
  headquarters in Colorado, Idaho, Minnesota, North Dakota, South Dakota,
  Wisconsin or Wyoming, or controlled a bank in Montana on 

                                       65
<PAGE>


  January 1, 1993; (ii) revising limits on detached teller facilities; and (iii)
  generally revising the laws relating to banking, including reducing the time
  between bank inspections, authorizing the acceptance of federal reports in
  lieu of examinations, clarifying the purpose of banking laws, applying the
  general corporate law to the formation and reorganization of banks, excluding
  repurchase agreements from the limitation on borrowing, revising bank
  investments, removing the limit on safe deposit functions, revising reserve
  requirements to comport with the requirements of the appropriate federal
  regulator that are currently in effect, and revising dissolution, closing and
  liquidation procedures.

       Legal Proceedings

       There are no material pending legal proceedings other than ordinary
  routine litigation to which BMS or its subsidiaries are or may be considered a
  party.  There are no material pending legal proceedings to which any director,
  officer, or affiliate of BMS is or may be a party adverse to BMS or has or may
  have a material interest adverse to BMS or any of its subsidiaries.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
                            OF FINANCIAL CONDITION

FINANCIAL REVIEW

   General

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

   The results reflect the operation of BMS's subsidiary banks, Bank of Montana 
and Montana Bank, its non-bank subsidiaries, and parent company operations. BMS 
acquired MBI in a cash transaction on March 31, 1993. Operations of MBI 
beginning April 1, 1993 are included in BMS's financial results. See 
"INFORMATION ABOUT BMS--Business" for a discussion of the MBI acquisition. In 
1992, Bank of Montana Anaconda was established to acquire certain assets and 
assume $29.6 million of deposit liabilities of First Security Bank of Anaconda, 
which was declared insolvent by the Montana Department of Commerce. In 1990, BMS
acquired Village Bank of Great Falls ("Village Bank") and Toole County State 
Bank of Shelby ("Toole County State Bank") in stock transactions. The combined
assets of Village Bank and Toole County State Bank was $76.5 million. (See 
Footnote 12 to the consolidated financial statements of BMS presented elsewhere 
herein).

COMPARISONS OF THREE MONTHS ENDED SEPTEMBER 30, 1993 AND 1992

   Earnings Performance 

   BMS recorded net income of $1.74 million and $1.29 million for the 
three-month periods ended September 30, 1993 and 1992, respectively. A 
discussion of the major components of net income follows. 

   Net Interest Income 

   Net interest income represents the difference between interest earned on 
assets and interest paid on liabilities. Changes in the types and volumes of 
earning assets and interest bearing liabilities, their related yields and
overall interest rates all can have a significant impact on net interest income.
For the three months ended September 30, 1993, net interest income, the largest 
component of earnings, increased to $7.8 million a 68.4% increase from the same 
period in 1992. The increase is primarily due to the acquisition of MBI. 
Excluding MBI, BMS's net interest income was $4.56 million for the third quarter
of 1993, versus $4.63 million a decrease of $74,000 or 1.6%. The relatively 
small change in net interest income results from the repricing of maturing 
assets more quickly than interest-bearing liabilities, compared to the prior 
year when interest-bearing liabilities were repricing more quickly, producing an
expanding net interest margin.
 
                                      67
<PAGE>

   Total interest income increased $4.6 million to $13.0 million, an increase of
54.8%. This increase was caused primarily by the acquisition of MBI. Excluding
MBI, total interest income decreased $.6 million, or 6.9%. This is a result of 
the low interest rate environment on investment securities. Individually, loan 
interest income was up $.2 million due to larger volumes, while investment 
interest income decreased $.8 million.

   Total interest expense increased 38.2% to $5.2 million for the three months 
ended September 30, 1993 as compared to the same period in 1992. Excluding MBI,
interest expense dropped $.5 million, or 13.3%. This drop is reflective of lower
interest rates in all deposit categories.

   Provision for Loan Losses

   The provision for loan losses increased to $126,000 for the three months 
ended September 30, 1993 compared to $63,000 for the comparable period in 1992. 
The provision for loan losses is based on management's assessment of the 
inherent risks in the loan portfolio and is calculated in an amount sufficient 
to maintain the allowance for loan losses at a level considered necessary to 
absorb estimated loan losses in the loan portfolio. Net charge-offs were $.31 
million for the three months ended September 30, 1993, compared to $50,000 in 
the same period of 1992. The increase in net charge-offs is a result of 
charge-offs of credit card receivables.

   Other Operating Income and Expenses

   Other operating income, which consists primarily of service charges on 
deposit accounts, gains on the sale of investment securities, customer fees and 
miscellaneous charges, increased by 71.7% during the three months ended
September 30, 1993 compared to the same period in 1992. Excluding the MBI 
acquisition, other operating income was up $.3 million, or 19.8%. This increase 
is a result of fees from the sale of annuities, credit life insurance and 
disability insurance and from fees on BMS's credit card base, which was up 10.2%
on personal credit cards, and was up 54.8% on merchant cards, over the same 
period a year ago.

   Other operating expenses, which consists of salaries and benefits, occupancy 
expenses, equipment expense, premiums paid to the Federal Deposit Insurance 
Corporation ("FDIC insurance"), legal expenses and other miscellaneous expenses,
increased 93% in 1993 over the comparable three month period in 1992. Excluding 
the effects of the acquisition of MBI, other operating expense went up $.68 
million, or 17.2%. Of this increase, $.45 million is attributed to salaries and
benefits. An increase of $115,000 of salaries occurred in the data center due to
increased data center activity. Also, incentive compensation was expensed 
entirely in the fourth quarter of 1992, but was spread over the third quarter 
and fourth quarter in 1993, and accounted for $105,000 of the increase.

   Income Taxes

   BMS files a consolidated federal income tax return with its subsidiaries. The
provision for income taxes includes taxes deferred to future periods resulting 
from timing differences in the recognition of income and expense for tax and 
financial reporting purposes. The effective tax rate differs from the federal 
statutory rate primarily as a result of nondeductible goodwill, nontaxable 
appreciation of key person life insurance surrender value and tax-exempt 
interest.

COMPARISONS OF NINE MONTHS ENDED SEPTEMBER 30, 1993 AND 1992

   Financial Condition

   Total consolidated assets increased $332.6 million during the first nine
months of 1993 to $797 million at September 30, 1993. This increase was 
primarily due to the acquisition of MBI. Without the MBI acquisition, assets of 
BMS would have decreased from $464 million on September 30, 1992 to $457 million
on September 30, 1993. This decrease in assets was due to a lack of deposit 
growth to fund new assets. Deposits decreased $3.2 million in BMS, excluding the
effect of the acquisition of MBI. The decrease in deposits is attributed in 
large part to the low interest rates being paid on deposit products such as 
Certificates of Deposits and money market accounts. Competition from investments
in mutual funds and the stock market have left many financial institutions with 
little or no deposit growth. MBI's deposits at September 30, 1993 were $280.9 
million.

   During the first nine months of 1993, outstanding loans increased from $244 
million to $386 million, an increase of $142 million. MBI accounted for the 
majority of the increase. Outstanding loans in MBI at the acquisition date of 
March 31, 1993, were $109 million. The balance of the increase in outstanding 
loans is the result of an increased effort by Bank of Montana and Montana Bank 
to generate new loans. Montana Bank loans increased from $109 million at 
acquisition date to $157 million on September 30, 1993.

   Allowance for Loan Losses

   The allowance for loan losses totaled $6.0 million as of September 30, 1993 
which represented 1.6% of all outstanding loans. As of December 31,1992 the 
allowance was $2.5 million or 1.01% of outstanding loans. BMS, excluding MBI, 
saw its reserve go from $2.5 million to $2.1 million at September 30, 1993. The
decrease is a result of net charge-offs exceeding provision expense. The 
allowance is maintained at a level deemed appropriate by management to 
adequately provide for known and inherent risks in the loan portfolio. The 
adequacy of the allowance is based on a continuous evaluation of the loan 
portfolio, recent loss experience and other pertinent factors, including current
and anticipated economic conditions.

   Nonaccrual loans as of September 30, 1993 were $.9 million, of which $.7 
million relate to the MBI acquisition. This compares to $.57 million, or .23% of
total outstanding loans, at December 31, 1992. The coverage ratio of nonaccrual 
loans (allowance for loan losses divided by nonaccrual loans) was 433.6%, at 
December 31, 1992. BMS places loans on nonaccrual status when management 
believes the collection of the loan is in jeopardy or if either the interest or 
principal becomes contractually past due by 90 days or more. If a loan is placed
on nonaccrual status, all interest previously accrued but not collected is 
reversed against current period interest income. Any interest received on such 
loans is then recognized as income when received.

                                      69
<PAGE>

  Earnings Performance

  BMS recorded net income of $4.9 million for the nine-month period ended 
September 30, 1993, compared to net income of $3.5 million for the comparable 
period in 1992. Discussion of the major components of net income follows.

  Net Interest Income

  For the nine months ended September 30, 1993, net interest income, the 
largest component of earnings, grew to $20.1 million a 56.8% increase from the 
same period in 1992. The increase is the result of the acquisition of MBI and of
interest rates on interest-bearing liabilities declining more than interest 
rates on interest-bearing assets. Also, on March 16, 1992, Bank of Montana 
Anaconda was established to acquire certain assets and assume the deposit 
liabilities of First Security Bank of Anaconda. Excluding the effects of MBI, 
net interest income increased for the first nine months to $14.1 million from 
$12.8 million. Of this increase, $.3 million is attributed to having the results
of Bank of Montana Anaconda included for a full nine months in 1993.

  Total interest income increased $9.3 million or 37.5% from one year ago. Most
of the increase is a result of the MBI acquisition. Excluding the effect of MBI,
overall interest income decreased $.6 million. Loan interest income increased
$2.3 million due to the increased volume of loans and a focus on more profitable
lending activities. Investment securities interest income decreased $2.9
million, due to reduced volumes and rates.

  Total interest expense for the nine months ended September 30, 1993, 
increased $2.1 million, or 17% to $14.1 million as compared to the same period 
in 1992. Excluding MBI, interest expense decreased $1.9 million. This decrease 
was the result of repricing interest-bearing liabilities in a decreasing rate 
environment during the first nine months of 1993.

  Provision for Loan Losses

  The provision for loan losses decreased to $.46 million for the nine months
ended September 30, 1993, compared to $.6 million for the comparable period in
1992. The provision for loan losses is based on management's assessment of the
inherent risks in the loan portfolio. Net charge-offs of $.9 million for the
nine months ended September 30, 1993 compares to net charge-offs of $.4 million
for the same period in 1992.

  Other Operating Income and Expenses

  Other operating income increased 37.3% to $6.7 million during the first 
nine-months of 1993 compared to the same period in 1992. The increase in other 
operating income from the MBI acquisition was partially offset by a decrease of 
$.9 million in net gains on sales of investment and mortgage-backed securities.

  Other operating expenses increased $7.3 million or 63.5% in 1993 over the 
comparable nine-month period in 1992. All categories of expenses increased as a 
result of the acquisition of MBI. Salaries and wages

                                      70
<PAGE>

and other expenses increased by $2.5 million and $2.8 million respectively. 
Excluding MBI, BMS had an increase of $1.4 million, or 12.7%. The most 
significant increases were found in credit card processing expenses, travel 
expenses and correspondent fees.

  Income Taxes

  The increase in income tax expense for the first nine months of 1993 as 
compared to the comparable period in 1992 was the result of the increase in 
pretax earnings. The effective tax rate differs from the federal statutory rate 
primarily as a result of nondeductible goodwill, nontaxable appreciation of key 
person life insurance surrender value and tax exempt interest.

COMPARISONS OF YEARS ENDED DECEMBER 31, 1992, 1991 AND 1990

  Earnings Performance

  BMS earned net income of $5.0 million in 1992, $4.0 million in 1991 and  $3.1
million in 1990. The increase in earnings from 1991 to 1992 was primarily due
to a 20% increase in net interest income and the acquisition of Bank of Montana
Anaconda. The increase in earnings from 1990 to 1991 was primarily due to
increases in net interest income. The increase in net interest income during 
these years is attributable to the decreasing interest rate environment and a 
concentrated effort by Bank of Montana to move funds from lower yielding assets 
such as government and agency securities and Federal Funds to higher yielding 
assets such as commercial and consumer loans. The consolidated return on average
assets was 1.10% in 1992 compared to .99% in 1991 and .91% in 1990. Return on 
average shareholders' equity was 17.6% in 1992 compared to 15.1% and 12.6%  in
1991 and 1990, respectively. On a per share basis, total earnings for the  years
1992, 1991 and 1990 were $3.86, $2.97 and $2.32, respectively.

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

  Net Interest Income

  Net interest income is affected by changes in both interest rates and  the
volume of average earning assets and interest-bearing liabilities. Interest 
bearing liabilities generally reprice more quickly than interest bearing assets 
in a decreasing rate environment. A dramatic increase in interest rates could 
significantly affect the gross interest spread of BMS.

  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 percent of the total change.

    Net interest income was $17.8 million in 1992, compared with $14.9 million 
in 1991 and $12.7 million in 1990. During 1991, interest rates in the United 
States began a general decline with short-term interest rates falling faster 
than long-term rates. This trend continued  throughout 1992. When this happens, 
a financial institution's cost of funds generally will fall faster than the 
yield on assets in which it is investing those funds. In this manner the net 
yield on interest-earning assets generally increases in a declining rate 
environment. Contributing to the increase in net interest income in 1992 was the
acquisition of Bank of Montana Anaconda, and in 1991 the acquisitions of Village
Bank and Toole County State Bank. 

    Total interest income decreased to $33.4 million or 3.8% in 1992 as compared
to $34.7 million in 1991, which was up from $30.9 million in 1990. Interest 
income was greatly affected by seven prime rate cuts during 1991 and one prime 
rate cut in 1992. Average earning assets increased to $422.1 million in 1992 
from $376.8 million in 1991 and $311.5 million in 1990. The increase in average 
earning assets during 1992 was primarily attributable to the acquisition of Bank
of Montana Anaconda. The 1991 increase over 1990 was largely due to the 
acquisition of Village Bank and Toole County State Bank. 

                                      74
<PAGE>
    Total interest expense in 1992 of $15.6 million declined from $19.9 million 
in 1991, or a decrease of 21.6%. This decline was attributable primarily to 
rates on interest-bearing liabilities declining to 4.21% in 1992, from 6.02% in 
1991. The 181 basis point decline from 1991 to 1992 was caused by the general 
economic and market conditions, which moved interest rates lower in 1992. Total 
interest expense in 1991 increased over 1990, when interest expense was $18.3 
million. Though rates continued lower in 1991, as pointed out by the rates paid
on interest-bearing  liabilities, acquisitions of Village Bank and Toole County
State Bank in 1990  caused 1991's interest expense to increase. 

    Provision for Loan Losses

    The allowance for loan losses is determined 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 this allowance and recoveries on charged-off loans are credited 
to this allowance. BMS's provision for loan losses was $.8 million, $.6 million 
and $.2 million in 1992, 1991 and 1990, respectively. 

    Net charge-offs in 1992 decreased to $.6 million from $.76 million in 
1991. Net charge offs were $.2 million in 1990. The ratio of net charge-offs 
to average loans in 1992 was .30% which was down from the 1991 ratio of .46%. 
The loan loss reserve as a percentage of loans was 1.01%, 1.22% and 1.39% at 
December 31, 1992, 1991 and 1990, respectively.

    Other operating income continues to be a significant source of revenues for 
BMS and increased $1.1 million or 22% in 1992 over 1991. This increase was 
partially attributed to a $.4 million increase in gains on sales of securities 
in 1992. The increase in service charges on deposit accounts from 1990 to 1991 
is primarily the result of a significant increase in deposit accounts relating 
to the acquisitions of Village Bank of Great Falls and Toole County State Bank 
in May and November of 1990 respectively. The increase in service charges on 
deposit accounts during 1992 can be attributed in part to the Bank of Montana 
Anaconda acquisition and to general increases in the level of service charges.

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

    Total other operating expenses increased to $15.4 million in 1992, compared 
to $13.4 million in 1991 and $11.3 million in 1990. The increase in 1992 is 
largely attributable to increases in salaries and benefits, FDIC insurance 
expense, and data processing expense. FDIC insurance increased $134,000 or 
16.4%, in 1992. The increase is due to the impact of increased premium rates as 
well as increased levels of deposits in the period. The increase in other 
operating expenses from 1990 to 1991 results from the acquisitions of Village 
Bank in May 1990 and Toole County State Bank in November 1990. The increase in 
salaries in 1992 was primarily the result of existing staff receiving annual 
increases based on their performance and the acquisition of Bank of Montana 
Anaconda. The increase in 1991 is primarily the result of the Village Bank of 
Great Falls and Toole County State Bank acquisitions in addition to normal
salary increases.

     Also included in operating expenses are management advisory service fees 
paid by BMS to Central Financial Services, Inc. a related party of BMS 
aggregating $779,000, $703,000 and $533,000 in 1992, 1991 and 1990, respectively
(See "THE MERGER--Interests of Certain Persons in the Merger; Certain 
Transactions" and footnote 11 to the consolidated financial statements of BMS 
contained elsewhere herein). The increase in 1991 over 1990, was the result of 
acquisitions which raised the assets of BMS, which is a component of the service
fee calculation. 

     Income Taxes

     The changes in income tax expense were primarily a result of the changes in
pretax earnings. The effective tax rate differs from the federal statutory rate 
primarily as a result of nondeductible goodwill, nontaxable appreciation of key 
person life insurance surrender value and tax-exempt interest.

    Funding Sources and Liquidity Management

    BMS relies primarily on its two subsidiary banks for sources of funding. The
cash flow from the subsidiary banks to BMS comes in the form of dividends and 
tax benefits. The subsidiary banks are restricted in paying dividends due to the
general regulatory capital requirements that apply to all banks. See "Capital 
Management of Bank Subsidiaries" below and "INFORMATION ABOUT BMS-Business-
Supervision and Regulation."

   BMS's Asset-Liability Committee is charged with the responsibility of 
maintaining an adequate level of liquidity for the subsidiary banks and managing
the risks associated with interest rate changes while sustaining stable growth 
in net interest income. BMS's basic strategy is to minimize interest rate risk 
through matching the repricing periods of earning assets and interest-bearing 
liabilities.

   The operations of the subsidiary banks are primarily funded through the use 
of borrowings in the form of demand and time deposits, negotiable certificates 
of deposit, and short-term funds. The maintenance of an adequate level of 
liquidity is necessary to ensure that sufficient funds are available to meet 
customers' loan demand and deposit withdrawals. The sources of asset liquidity 
consist of federal funds, maturing loans and short-term marketable securities. 

   Capital Management of Bank Subsidiaries

   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 final 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. In late 1990, the Federal Reserve Board adopted a 
minimum ratio of Tier 1 capital to total assets of 3%, known as the 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 base. The
definition of Tier 1 capital for the leverage ratio is the same as the December 
31, 1992 Tier 1 capital definition in the risk-based capital guidelines. The
FDIC adopted final  regulations, effective June 16, 1992 defining what capital
ratios were necessary to be "well capitalized." The subsidiary banks' actual
risk-based  capital, risk-based capital ratios, risk-weighted assets, and
leverage ratios at September 30, 1993 and December 31, 1992, are summarized as
follows:

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

    Disclosures About Market Value of Financial Instruments

    In December 1992 the Financial Accounting Standards Board ("FASB") issued 
Statement of Financial Accounting Standards No. 107 (SFAS No. 107) entitled 
Disclosures About Fair Value of Financial Instruments. SFAS No. 107 requires all
entities to disclose the fair value of financial instruments (both assets and 
liabilities recognized and not recognized in the statement of financial 
position) for which it is practicable to estimate fair value, except those 
financial instruments specifically excluded. The disclosure shall be either in 
the body of the financial statements or in the accompanying notes and shall also
include the methods and significant assumptions used to estimate the fair value 
of financial instruments. Certain information shall also be disclosed if it is 
not practicable for an entity to estimate the fair value of a financial 
instrument or a class of financial instruments as well as the reasons why it is 
not practicable to estimate the fair value. SFAS No. 107 is effective for 
financial statements issued for fiscal years ending after December 15, 1992 and 
the required disclosure is included in Note 17 of the consolidated financial 
statements of BMS.

    Accounting for Income Taxes

    On February 10, 1992 the FASB issued Statement of Financial Accounting 
Standards No. 109 (SFAS No. 109), Accounting for Income Taxes. This statement 
has superseded both Accounting Principals Board (APB) No. 11 and SFAS No. 96, 
the previous authoritative literature on income tax accounting.

    SFAS No. 109 calculates taxes on the liability method; thus requiring the 
recognition of current and deferred tax liabilities and assets for the expected 
future tax consequences of events that have been recognized in the financial 
statements or tax return. Under SFAS No. 109, the tax expense or benefit in the 
statement of operations will be the current tax liability plus the change in 
deferred tax liabilities and assets occurring during the year. This statement's 
emphasis on the balance sheet is consistent with SFAS No. 96, but is a change 
from APB No. 11's emphasis on the expense calculation.

    SFAS No. 109 is effective for fiscal years beginning after December 15, 
1992, with retroactive restatement permitted and earlier application encouraged.
Adoption of the statement in 1993 is not expected to have a material impact on 
the financial statements of BMS. 

    Accounting for Investment Securities

    In May 1993 the FASB issued Statement of Financial Accounting Standards 
No. 115 (SFAS No. 115), Accounting for Certain Investments in Debt and Equity 
Securities. This statement addresses the accounting and reporting for 
investments that have readily determinable fair values. Those investments are to
be classified in three categories and accounted for as follows:

1.  Debt Securities that the enterprise has the positive intent and ability to 
    hold to maturity are classified as held-to-maturity securities and reported 
    at amortized cost.

                                      79
<PAGE>
2.  Debt and equity securities that are bought and held principally for the 
    purpose of selling them in the near term are classified as trading
    securities  and reported as fair value, with unrealized gains and losses
    included in  earnings. 

3.  Debt and equity securities not classified as either held-to-maturity 
    securities or trading securities are classified as available-for-sale 
    securities and reported at fair value, with unrealized gains and losses
    excluded from earnings and reported in a separate component of shareholder's
    equity. 

    The Statement does not apply to unsecuritized loans. However, after mortgage
loans are converted to mortgage-backed securities, they are subject to its 
provisions. The Statement supersedes SFAS No. #12, Accounting for Certain 
Marketable Securities, and amends SFAS No.#65, Accounting for Certain Mortgage 
Banking Activities, to eliminate mortgage-backed securities from its scope. SFAS
No. 115 is effective for fiscal years beginning after December 15, 1993.

    BMS will implement SFAS No. 115 on January 1, 1994, by properly classifying 
all securities into either the held-to-maturity investment account or the 
available-for-sale account. BMS has not used a trading account in the past and 
has no current plans to begin using one.

                      RECENT OPERATING RESULTS OF NORWEST


       Norwest's net income was $653.6 million for the year ended December 31,
  1993, an increase of 48.5% over the $440.1 million earned in 1992.  Net income
  per common share was $2.13 for the year ended December 31, 1993, compared with
  $1.42 in 1992, an increase of 50.4%.  Return on common equity was 20.9% and
  return on assets was 1.38% for the year ended December 31, 1993, compared with
  15.2% and 1.03%, respectively, in 1992.

       Norwest reported net income of $175.0 million for the quarter ended
  December 31, 1993, a 167.1% increase over the $65.6 million earned in the
  fourth quarter of 1992.  Net income per common share was $0.57 for the fourth
  quarter of 1993, compared with $0.20 for the same quarter of 1992.  Return on
  assets was 1.37% and return on common equity was 21.3% for the quarter ended
  December 31, 1993, compared with 0.59% and 8.3%, respectively, for the fourth
  quarter of 1992.

       The 1992 results have been restated for the 2-for-1 stock split (effected
  in the form of a 100% stock dividend) distributed on June 28, 1993, and
  include Lincoln Financial Corporation (Lincoln), acquired on February 9, 1993,
  in a pooling of interests transaction. The fourth quarter of 1992 results
  include $93.5 million pre-tax charges taken by Lincoln to conform their credit
  and accounting practices to those of Norwest and other restructuring-related
  charges.  The 1992 annual results, for comparative purposes, do not include a
  one-time special charge of $76.0 million, or $0.26 per common share, related
  to Norwest's early adoption of Statement of Financial Accounting Standards No.
  106, Employers' Accounting for Postretirement Benefits Other Than Pensions.

       Consolidated tax-equivalent net interest income was $2,408.7 million and
  $627.4 million for the year and quarter ended December 31, 1993, compared with
  $2,114.7 million and $575.4 million, respectively, in 1992, increases of 13.9
  percent and 9.0 percent, respectively.  The increase for the year is primarily
  due to an 11.3% increase in average earning assets and a 13 basis point
  increase in net interest margin.  The increase from the fourth quarter of 1992
  is due to a 14.2 percent increase in average earnings assets, partially offset
  by a 25 basis point decrease in net interest margin.

       Norwest provided $140.1 million and $40.5 million for credit losses for
  the year and quarter ended December 31, 1993, or 0.56% and 0.61% of average
  loans and leases, compared with $266.7 million and $112.2 million,
  respectively, or 1.22% and 1.95% of average loans and leases, for the same
  periods in 1992.  The 1992 provision includes $60.0 million for credit losses
  taken by Lincoln during the fourth quarter.  Net credit losses totaled $173.6
  million and $61.9 million for the year and quarter ended December 31, 1993,
  compared with $217.6 million and $64.3 million, respectively, for the same
  periods in 1992.

       As a percent of average loans and leases, net credit losses were 0.70%
  and 0.93% for the year and quarter ended December 31, 1993, compared with
  1.00% and 1.12% for the same periods in 1992.

       Non-performing assets, including non-accrual, restructured, and 90-day
  past due loans and leases, and other real estate owned, totaled $285.5
  million, or 0.6% of total assets, at December 31, 1993, compared with $372.7
  million, or 0.8%, at December 31, 1992.  The 

                                       88
<PAGE>


  decrease is primarily due to a $29.6 million, $23.5 million and $36.2 million
  reduction in real estate non- accrual loans, commercial non-accrual loans and
  other real estate owned, respectively, partially offset by a $5.1 million
  increase in restructured loans.  The allowance for credit losses was $744.9
  million at December 31, 1993, and represents 260.9% of non-performing assets.

       Norwest consolidated non-interest income was $1,542.5 million and $426.0
  million for the year and quarter ended December 31, 1993, compared with
  $1,228.8 million and $305.0 million, respectively, for the same periods in
  1992.  The full year increase from 1992 reflects growth in mortgage banking
  revenues, net venture capital gains and various fee-based services, partially
  offset by decreases in credit card fees, trading account gains and net gains
  on investment securities available for sale.  Excluding gains on
  investment/mortgage-backed securities, venture capital gains, and gains on
  investment/mortgage-backed securities available for sale, non-interest income
  was up 26.1% over 1992.

       Non-interest expenses were $2,840.8 million and $750.4 million for the
  year and quarter ended December 31, 1993, compared with $2,436.6 million and
  $660.8 million, respectively, for the same periods in 1992.  The increase for
  the year ended December 31, 1993 is primarily attributable to an increase in
  salaries and benefits at both the mortgage banking operations to support large
  volume increases in originations and servicing, and at Norwest Financial
  Services, Inc., due to the acquisition in the fourth quarter of 1992 of Trans
  Canada Credit Corporation, Ltd., and increased charitable contributions.

       Norwest's banking group reported earnings of $397.2 million and $108.6
  million for the year and quarter ended December 31, 1993, compared with $227.7
  million and $8.0 million respectively, for the same periods in 1992.  Included
  in the fourth quarter of 1992 banking group results are Lincoln's special
  provision for credit losses, merger and transition related expenses and
  restructuring costs totaling $93.5 million before income taxes. Mortgage
  banking operations earned $56.3 million and $10.2 million for the year and
  quarter ended December 31, 1993, compared with $53.4 million and $9.4 million,
  respectively, for the same periods in 1992.  Norwest Financial Services, Inc.
  (commercial and consumer finance) reported earnings of $200.1 million and
  $56.2 million for the year and quarter ended December 31, 1993, compared with
  $159.0 million and $48.2 million, respectively, for the same periods in 1992.

       At December 31, 1993, total assets were $50.8 billion, compared with
  $46.7 billion at December 31, 1992.  The increase is primarily due to a $4.3
  billion increase in loans and leases, and student loans and mortgages held for
  sale, including $2.6 billion of loans and leases acquired in acquisitions
  completed during 1993.  This increase was partially offset by a $0.4 billion
  decrease in investment securities and investment securities available for
  sale. Total long-term debt at December 31, 1993, was $6.8 billion compared
  with $4.5 billion at December 31, 1992.  This increase is primarily due to a
  net increase of $1.0 billion of Federal Home Loan Bank advances by subsidiary
  banks of Norwest and a net increase of $1.0 billion of long-term debt issued
  by Norwest.  Total stockholders' equity was $3.6 billion at December 31, 1993,
  compared with $3.1 billion at December 31, 1992.  See "INCORPORATION OF
  CERTAIN DOCUMENTS BY REFERENCE."

                       CERTAIN REGULATORY CONSIDERATIONS

  GENERAL

      As a bank holding company, Norwest is subject to the supervision of the
  Federal Reserve Board.  Norwest's banking subsidiaries are subject to
  supervision and examination by applicable federal and state banking agencies.
  All of Norwest's banking subsidiaries are insured, and therefore 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.

      Norwest is a legal entity separate and distinct from its banking and
  nonbanking subsidiaries.  Accordingly, the right of Norwest, and thus the
  right 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.

  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 September 30, 1993, without obtaining prior regulatory approval, aggregate
  dividends of at least $136.3 million.  The payment of dividends by any
  subsidiary bank may also be affected by other factors, such as the maintenance
  of adequate capital for such subsidiary bank.

      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 insured banks and bank holding companies should generally pay
  dividends only out of current operating earnings.

  HOLDING COMPANY STRUCTURE

      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 

                                       90
<PAGE>


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

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

      In January 1989, the Federal Reserve Board issued final risk-based capital
  guidelines for bank holding companies, such as Norwest.  The new guidelines,
  which became effective December 31, 1990, were phased in over two years.  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 composed of common equity, retained 
  earnings, and a limited amount of 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 approved in August 1990 final minimum "leverage ratio" (the ratio of
  Tier 1 capital to quarterly average total assets) guidelines for bank holding
  companies and state member banks.  These guidelines provide for a minimum
  leverage ratio of 3% for bank holding companies and 

                                       91
<PAGE>


  state member banks that meet certain specified criteria, including that they
  have the highest regulatory rating. All other bank holding companies and state
  member banks will be required to maintain a leverage ratio of 3% plus an
  additional cushion of 100 to 200 basis points.  The guidelines also provide
  that banking organizations experiencing internal growth or making acquisitions
  will be expected to maintain strong capital positions substantially above the
  minimum supervisory levels, without significant reliance on intangible assets.
  Furthermore, the guidelines indicate that the Federal Reserve Board will
  continue to consider a "tangible Tier 1 leverage ratio" in evaluating
  proposals for expansion or new activities.  The tangible Tier 1 leverage ratio
  is the ratio of a banking organization's Tier 1 capital, less all intangibles,
  to total assets, less all intangibles.  Each of Norwest's banking subsidiaries
  is also subject to capital requirements adopted by applicable regulatory
  agencies which are substantially similar to the foregoing.  At September 30,
  1993, Norwest's Tier 1 and total capital (the sum of Tier 1 and Tier 2
  capital) to risk-adjusted assets ratios were 9.80% and 12.42%, respectively,
  and Norwest's leverage ratio for the quarter ended September 30, 1993, was
  6.81%.  Neither Norwest nor any subsidiary bank has been advised by the
  appropriate federal regulatory agency of any specific leverage ratio
  applicable to it.

      The Federal Reserve Board has adopted changes to its risk-based and
  leverage ratio requirements applicable to bank holding companies and state
  chartered member banks that require that all intangibles, including core
  deposit intangibles, purchased mortgage servicing rights ("PMSRs"), and
  purchased credit card relationships ("PCCRs") be deducted from Tier 1 capital.
  The changes, however, grandfather identifiable assets (other than PMSRs and
  PCCRs) acquired on or before February 19, 1992, and permit the inclusion of
  readily marketable PMSRs and PCCRs in Tier 1 capital to the extent that (i)
  PMSRs and PCCRs do not exceed 50% of Tier 1 capital and (ii) PCCRs do not
  exceed 25% of Tier 1 capital.  For such purposes, PMSRs and PCCRs each would
  be included in Tier 1 capital only up to the lesser of (a) 90% of their fair
  market value (which must be determined quarterly) and (b) 100% of the
  remaining unamortized book value of such assets.  The OCC has adopted
  substantially similar regulations.  Management does not expect the foregoing
  changes to have a material impact on the results of operations of Norwest.

  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 revises
  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 agencies to take
  "prompt corrective action" in respect of depository institutions that do not
  meet minimum capital requirements.  FDICIA establishes five capital tiers:
  "well capitalized," "adequately capitalized," "undercapitalized,"
  "significantly undercapitalized," and "critically undercapitalized."  A
  depository institution's capital tier will depend upon where its capital
  levels are in relation to various relevant capital measures, which will
  include a risk-based capital measure and a leverage ratio capital measure, and
  certain other factors.

      A depository institution is well capitalized if it significantly exceeds
  the minimum level required by regulation for each relevant capital measure,
  adequately capitalized if it meets each such measure, undercapitalized if it
  fails to meet any such measure, significantly 

                                       92
<PAGE>


  undercapitalized if it is significantly below any such measure, and critically
  undercapitalized if it fails to meet any critical capital level set forth in
  regulations.  The critical capital level must be a level of tangible equity
  equal to not less than 2% of total assets and not more than 65% of the minimum
  leverage ratio to be prescribed by regulation (except to the extent that 2%
  would be higher than such 65% level).  An institution may be deemed to be in a
  capitalization category that is lower than is indicated by its actual capital
  position if, among other things, it receives an unsatisfactory examination
  rating.

      Under regulations adopted pursuant to the foregoing provisions, for an
  institution to be well capitalized it must have a Tier 1 risk-based capital
  ratio of a least 6%, a total risk-based capital ratio of at least 10%, and a
  leverage ratio of at least 5%, and not be subject to any specific capital
  order or directive.  For an institution to be adequately capitalized it must
  have a Tier 1 risk-based capital ratio of at least 4%, a total risk-based
  capital ratio of at least 8%, and a leverage ratio of a least 4% (and in some
  cases 3%).  As of September 30, 1993, all of Norwest's banking subsidiaries
  were well capitalized.

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

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

      FDICIA directs that each federal banking agency prescribe standards for
  depository institutions and depository institution holding companies relating
  to internal controls, information systems, internal audit systems, loan
  documentation, credit underwriting, interest rate exposure, asset growth,
  compensation, a maximum ratio of classified assets to capital, minimum
  earnings sufficient to absorb losses, a minimum ratio of market value to book
  value for publicly traded shares, and such other standards as the agency deems
  appropriate.  The impact of such standards on Norwest cannot 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 

                                       93
<PAGE>


  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 well capitalized if it
  maintains a leverage ratio of at least 5%, a ratio of Tier 1 capital to risk-
  adjusted assets of at least 6%, and a ratio of total capital to risk-adjusted
  assets of at least 10%, and is not otherwise in a "troubled condition" as
  specified by the appropriate federal regulatory agency.  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 September 30, 1993, 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") and the Savings Association Insurance Fund
  ("SAIF") 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 or SAIF 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% (or undercapitalized Subgroup C institutions).  Adequately capitalized
  institutions will be assigned assessment rates ranging from 0.26% to 0.30%.
  Norwest incurred $66.2 million of FDIC insurance expense in 1993.  Because of
  decreases in the reserves of the BIF and SAIF due to the increased number of
  bank failures in recent years, it is possible the BIF and SAIF premiums will
  be further increased and it is possible that there may be a special
  assessment.  Any such further increase or special assessment would also
  decrease net income, and a special assessment could have a material adverse
  effect on the results of operations of Norwest.

                        Report of Independent Auditors
                        ------------------------------



The Board of Directors and Stockholders
Bank of Montana System:

We have audited the accompanying consolidated balance sheets of Bank of Montana
System and subsidiaries as of December 31, 1992 and 1991 and the related
consolidated statements of income, changes in stockholders' equity and cash
flows for each of the years in the three-year period ended December 31, 1992.
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 Bank of Montana
System and subsidiaries at December 31, 1992 and 1991 and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1992 in conformity with generally accepted accounting
principles.

                      Three Years Ended December 31, 1992


(1)  Summary of Significant Accounting Policies
     ------------------------------------------

     General - Bank of Montana System and subsidiaries (the Company) provides a
     full range of banking services to individual and corporate customers
     through its subsidiary and branch offices throughout the state of Montana. 
     The Company is subject to competition from other financial institutions and
     financial service providers.  The Company is subject to the regulations of
     certain Federal and state agencies and undergoes periodic examinations by
     those regulatory authorities.

     The consolidated financial statements include the accounts of Bank of
     Montana System (Parent) and its subsidiaries, Bank of Montana, Bank of
     Montana - Butte, and five non-bank subsidiaries.  Effective September 1,
     1992, seventeen former subsidiaries were merged into Bank of Montana.  The
     previously existing subsidiaries are now operating as branch offices in the
     same locations.  All material intercompany balances have been eliminated.

     Basis of Presentation - The financial statements have been prepared in
     conformity with generally accepted accounting principles.  In preparing the
     financial statements, management is required to make estimates and
     assumptions that affect the reported amounts of assets and liabilities as
     of the date of the balance sheet and revenues and expenses for the period. 
     Actual results could differ significantly from those estimates.

     Material estimates that are particularly susceptible to significant change
     in the near-term relate to the determination of the allowance for loan
     losses.  In connection with the determination of the allowances for loan
     losses, management obtains independent appraisals for significant
     properties.  Management believes that the allowances 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
     banks' allowance for losses on loans.  Such agencies may require the banks
     to recognize additions to the allowance based on their judgements about
     information available to them at the time of their examination.

     Cash and Cash Equivalents - For purposes of reporting cash flows, cash and
     cash equivalents include cash on hand and amounts due from banks.  Federal
     funds are purchased and sold on a consolidated basis and are generally
     bought and sold for one day periods.

     Aggregate average reserves in the form of deposits with the Federal Reserve
     Bank of $205,000 ($623,000 in 1991) were maintained in conjunction with
     satisfying Federal regulatory reserve requirements for 1992.  No
     compensating balances are required to be maintained with correspondent
     banks as compensation for check clearing services.

     Investment Securities - Investment securities are segregated based on
     whether the investments are held for short-term appreciation in market
     value or for long-term investment.  At December 31, 1992 and 1991 there
     were no securities held for short term appreciation.

     Investment securities held for long-term investment are stated at cost,
     adjusted for amortization of premium and accretion of discount which are
     recognized as adjustments to interest income using the straight-line
     method.  The results of using the straight-line method do not differ
     materially from results using the interest method.  Such securities are
     also subject to adjustments, if any, for permanent impairments in value. 
     At December 31, 1992 and 1991 no such adjustments were necessary.
                                                                     (Continued)

                  Notes to Consolidated Financial Statements


     Gains and losses from sales of investment securities are based on the net
     proceeds and the adjusted carrying amount of the securities sold using the
     specific identification method and reported "net" in other operating income
     in the consolidated statements of income.

     Loans - Secured and unsecured loans are stated at the principal amount
     outstanding net of unearned discount and reserve for loan losses.  Interest
     on commercial, real estate and certain consumer loans is credited to income
     based upon the principal amount outstanding.  Unearned discount on other
     consumer loans is recognized as income over the terms of the loans by using
     principal amounts outstanding.

     Loans on which the accrual of interest has been discontinued are designated
     as nonaccrual loans.  Accrual of interest on loans is discontinued when
     either reasonable doubt exists as to the full, timely collection of
     interest or principal or, when the loan becomes contractually past due by
     ninety days or more with respect to interest or principal unless such past
     due loan is well secured and in the process of collection.  When a loan is
     placed on nonaccrual status, all interest previously accrued but not
     collected is reversed against current period interest income unless
     principal and interest are well secured by sound collateral values. 
     Interest accruals are resumed on such loans only when they are brought
     fully current with respect to interest and principal and when, in the
     judgement of management, the loans are estimated to be fully collectible as
     to both principal and interest.

     Restructured rate loans are loans that have been restructured to provide
     for a reduction of the originally contracted principal and/or rate of
     interest as a result of a weakening in the financial position of the
     borrower.  Interest income on these loans is accrued at the restructured
     rate.

     Loan Fees - Net loan origination fees, if significant, are recognized as
     interest income over the life of the related loans as an adjustment of the
     interest yield.

     Reserve for Loan Losses - The reserve for loan losses is maintained through
     a provision for loan losses which is charged to expense.  Loans are charged
     against the reserve for loan losses when management believes that the
     collectibility of the principal is unlikely.  The reserve is maintained at
     an amount that management believes will be adequate to absorb losses
     inherent in existing loans, leases, and commitments to extend credit, based
     on evaluations of collectibility, collateral values, and prior loss
     experience.  The evaluations take into consideration such factors as
     changes in the nature and volume of the portfolio, overall portfolio
     quality, loan concentrations, specific problem loans, leases, and
     commitments, and current and anticipated economic conditions that may
     affect the borrowers' ability to pay.

     Premises and Equipment - Bank premises and equipment are stated at cost
     less accumulated depreciation and amortization, which is charged to
     operating expense over the estimated useful lives of the respective assets
     using the straight-line method for bank premises and accelerated and
     straight-line methods for equipment.  Consolidated depreciation expense was
     $846,080, $795,585 and $688,392 for 1992, 1991 and 1990, respectively. 
     Repairs and maintenance costs are charged to expense as incurred.

     Intangible Assets - The excess of purchase price over equity in net assets
     acquired after October 31, 1970, is being amortized over twelve to forty
     years. The remainder ($884,610 at December 31, 1992) is not being amortized
     since, in the opinion of management, there has been no decline in value of
     the assets and business markets acquired.

     The excess of purchase price over equity in net assets of the data
     processing facility acquired in 1987 of $234,000 is being amortized over 12
     years.  The value of service contracts acquired in this acquisition of
     $1,330,000 is being amortized over 8 years, based on an evaluation of
     contract terms, equipment leases, software owned and other factors.
                                                                     (Continued)

     Cash Surrender Value of Life Insurance - The Company maintains life
     insurance policies on certain of its key officers whereby the cash
     surrender value is received if the policy is terminated, or the death
     benefit is received upon the death of the insured.

     Other Real Estate Owned - Other real estate owned represents property
     acquired in satisfaction of loans, including in-substance foreclosure.  At
     time of acquisition other real estate is recorded at the lower of the
     Bank's carrying value of the related loan or the asset's fair market value
     which becomes the property's new carrying value.  Any write-downs at date
     of acquisition are charged to the allowance for loan losses.  Expenses, net
     of related income, incurred in maintaining assets and subsequent
     write-downs to reflect declines in the net realizable value of the property
     are included in other operating expenses.

     A loan is deemed foreclosed in-substance when it has been determined that
     repayment in full is not expected and the borrower has little or no equity
     in the collateral and is not expected to be able to rebuild equity in the
     foreseeable future.

     Income Taxes - The Parent Company and its subsidiaries have elected to be
     included in a consolidated Federal income tax return.  State statute
     currently prevents the Bank from filing a consolidated Montana income tax
     return with the Parent and, accordingly, separate returns are filed and
     taxes paid by the Parent Company and each bank subsidiary.  Federal income
     taxes attributable to the subsidiaries, computed on a separate return
     basis, are paid to or received from the Parent Company.

     The income tax effects of transactions are recognized for financial
     reporting purposes in the year in which they enter into determination of
     recorded income, regardless of when the transactions are recognized for tax
     purposes. Accordingly, applicable income taxes in the consolidated
     statements of income include charges or credits for deferred income taxes
     relating to such temporary differences.  These deferred income taxes are
     recognized for these temporary differences by applying enacted statutory
     tax rates applicable to future years to differences between the financial
     statement carrying amounts and the tax bases of existing assets and
     liabilities.  The effect on deferred taxes of a change in tax rates is
     recognized in income in the period that includes the enactment date.

     In February 1992, the Financial Accounting Standards Board issued Statement
     of Financial Accounting Standards No. 109, "Accounting for Income Taxes"
     (the Statement).  The Statement requires certain changes to the asset and
     liability method of accounting for income taxes, primarily related to the
     recognition of deferred tax assets.  Adoption of the Statement in 1993 is
     not expected to have a material impact on consolidated earnings or
     financial position.

     Earnings Per Share - Earnings per common share is computed by dividing net
     income by the weighted average number of common shares outstanding during
     the period.

     Reclassification - Certain reclassifications have been made to the prior
     years' financial statements amounts to conform to the 1992 presentation.
                                                                     (Continued)

     Proceeds from sale of investment securities were $49,110,818 and
     $92,910,000 in 1992 and 1991, respectively.  Gross gains of $1,368,192 and
     $986,054, and gross losses of $12,574 and $25,894 were realized on sales of
     investment securities in 1992 and 1991, respectively.

     Maturities of the investment securities by contractual maturity at December
     31, 1992 are shown below.  Maturities of securities do not reflect rate
     repricing opportunities present in many adjustable rate mortgage-backed and
     corporate securities, nor do they reflect expected shorter maturities based
     upon early prepayments of principal.  At December 31, 1992, approximately
     $102,215,000 of floating rate securities are included in maturities of
     mortgage-backed and other investment securities beyond five years.

     The Company had no concentrations of loans to borrowers engaged in other
     industry classifications which exceeded 10% of total loans other than
     disclosed above.

     Nonaccrual loans amounted to $572,000, $1,297,000, and $1,031,000 at
     December 31, 1992, 1991 and 1990, respectively.  If interest on these loans
     had been accrued, such income would have approximated $77,000, $121,000 and
     $65,000, respectively.  Included in total loans at December 31, 1992 and
     1991 are loans with a carrying value of $427,000 and $719,000,
     respectively, the terms of which have been modified in troubled debt
     restructurings.  Interest is generally accrued on such loans in accordance
     with the renegotiated terms.  At December 31, 1992, there were no
     commitments to lend additional funds to borrowers whose existing loans have
     been restructured or are classified as nonaccrual.

     Over 77% of the Company's loan activity is with customers within the state
     of Montana.  At December 31, 1992, $56,000,000 of loans or purchased
     participation loans were acquired where the customers are out of the state.
     Included in this balance is $10,987,000 of mortgages and other loans from
     companies and individuals secured by homes, autos, trucks, and recreational
     vehicles. Anticipated credit losses arising from these transactions compare
     favorably with the Company's credit loss experience of its loan portfolio
     as a whole.

</TABLE>

     The Company's adjustable rate term loan payable is secured by all stock
     owned in the Company's bank subsidiaries.  The term loan agreement contains
     various restrictive covenants including limitations on capital spending and
     acceleration of maturity in the event of four consecutive quarters of
     operating losses in any subsidiary bank or the Parent Company.

     The Company has a $100,000 revolving line of credit with interest at prime
     rate (6% at December 31, 1992).  The line of credit is also secured by all
     stock of the subsidiary banks.  The line of credit must be fully repaid for
     thirty consecutive days each year.  At December 31, 1992, this line of
     credit was unused.  Further, one of the subsidiary banks has a $10,000,000
     Federal Funds line of credit for seasonal needs.  At December 31, 1992,
     this line of credit was unused.

     Approximate maturities of notes and contracts payable for the five years
     subsequent to December 31, 1992 are as follows: $600,550 in 1993; $750,550
     in 1994; $1,000,550 in 1995; $1,300,550 in 1996; and $1,550,550 in 1997.

(10) Employee Benefit Plans
     ----------------------

     The Company provides a Cash or Deferred Profit Sharing Plan and Trust (the
     Plan) which covers substantially all employees.  Under the Plan, employees
     may elect to contribute a percentage of their monthly compensation to the
     Plan.  The employee's funds, in addition to a 75% employer matching
     contribution (within certain limits), are used to purchase investments for
     the accounts of the participating employees.  Employer contributions to the
     plan were approximately $128,000, $83,000 and $62,000 in 1992, 1991 and
     1990, respectively.

     The Plan was the resultant entity from the merger of a previously existing
     401(k) plan and an Employee Stock Ownership Plan (ESOP), which covered
     substantially all employees.  Contributions (expense) to the ESOP were
     $49,500 and $198,000 in 1991 and 1990, respectively.  The Company had
     assumed certain obligations of the ESOP.  The Company had also committed to
     make contributions to the ESOP sufficient to repay the ESOP obligations
     assumed.  Payments on the ESOP obligations funded by the Company's ESOP
     contributions were charged to employee benefit expense for the principal
     portion and interest expense for the interest.  The deferred charge against
     stockholders' equity was also reduced as ESOP obligation principal payments
     were made.  Interest expense components of ESOP contributions were
     approximately $18,000 and $80,000 in 1991 and 1990, respectively.
                                                                     (Continued)

                  Notes to Consolidated Financial Statements


     During 1991, the Parent Company and a subsidiary redeemed 6,400 and 21,200
     shares, respectively, of the Company's common stock from the ESOP and the
     ESOP subsequently paid off its remaining debt.  The 52,591 shares of stock
     owned by the ESOP have been allocated to the plan participants.  The
     Company is obligated to redeem shares of plan participants upon retirement
     or termination.

     In addition to the Plan, the Company provides post retirement death
     benefits for certain key employees as an inducement to continue employment
     through age 65.  The Company currently has one employee eligible for
     benefits under the plan.  There were no benefits paid in 1992, 1991 or 
     1990.

(11) Related Party Transactions
     --------------------------

     The Parent Company has entered into a comprehensive service agreement with
     Central Financial Services, Inc. (CFS) of Golden Valley, Minnesota.  CFS is
     owned by the Chairman of the Board of Directors of the Company.  CFS
     provides certain advisory and consulting services to the Company's
     subsidiary banks. Fees paid to CFS amounted to $779,000 in 1992, $703,000
     in 1991 and $533,000 in 1990.  1992 fees include ten months' assessment on
     the bank acquired in 1992.  1991 fees include a full years' assessment on
     the two additional banks acquired in 1990.  Fees charged are based on
     actual costs and other services provided by CFS.

     Certain officers and directors of the subsidiary banks and the Parent
     Company and certain corporations and individuals related to such persons
     incurred indebtedness of approximately $178,000 in the form of loans, as
     customers of the subsidiary banks.  These loans were made on substantially
     the same terms, including interest rates and collateral, as those
     prevailing at the time for comparable transactions with other customers and
     did not involve more than normal risk of collectibility.

     The Parent Company and subsidiaries have, in the normal course of business,
     other arms length transactions with related parties.

(12) Acquisition of Subsidiary Banks
     -------------------------------

     On March 17, 1992, the Company acquired certain assets and liabilities of a
     closed financial institution in Anaconda, Montana from the Federal Deposit
     Insurance Corporation (FDIC).  The amount of liabilities assumed was
     $29,640,125 for which the Company received assets valued at $29,513,125. 
     Goodwill of $127,000 was recorded at acquisition.  Certain assets acquired
     were subject to a put-back agreement whereby the FDIC would repurchase
     those assets from the Company.

     On May 1, 1990, the Company acquired all of the outstanding common stock of
     Big Sky Bankshares, Inc. (Big Sky).  Big Sky owned 100% of the stock of
     Village Bank of Great Falls, Montana (Village), a state chartered bank. 
     Both Big Sky and the Company obtained independent third party appraisals to
     determine the exchange ratio.  Big Sky was jointly owned by the Chairman of
     the Board of Directors and an officer of the Company (controlling
     shareholders).

     The Company issued 117,350 shares of its common stock and assumed
     $1,350,000 of Big Sky's debt in exchange for all of the shares of Big Sky. 
     This transaction between the Company and the controlling shareholders was
     accounted for as a purchase transaction using the controlling shareholders'
     historical cost.  The unaudited net book value of Village at May 1, 1990
     was $2,437,170 which included net intangible assets of $389,500.
                                                                     (Continued)

     The operations of Big Sky and Village are included in the consolidated
     statement of income beginning May 1, 1990.

     On November 1, 1990, the Company acquired all of the outstanding common
     stock of Toole County State Bank, Shelby, Montana (Shelby), a state
     chartered bank. The exchange ratio was determined by independent third
     party appraisals.  Shelby was also jointly owned by the controlling
     shareholders.

     The Company issued 82,811 shares of its common stock and assumed 
     $5,000,000 of the controlling shareholder's debt in exchange for all of 
     the shares of Shelby.  This transaction between the Company and the 
     controlling shareholders was accounted for as a purchase transaction 
     using the controlling shareholders' historical cost.  The unaudited net 
     book value of Shelby at November 1, 1990 was $5,572,253.

     The operations of Shelby are included in the consolidated statement of
     income beginning November 1, 1990.

(13) Commitments and Contingent Liabilities
     --------------------------------------

     On August 31, 1992, the Company entered into an agreement to purchase all
     of the outstanding capital stock of Montana Bancsystems, Inc., for $19 per
     share for a total of approximately $39,000,000.  Approval of the
     transaction was granted on March 1, 1993 by the Federal Reserve Bank of
     Minneapolis.  Final closing is expected to occur on or about March 31,
     1993.

     The transaction will be financed by the sale to shareholders of 
     $22,500,000 of newly issued common stock of the Company.  Additional 
     borrowings on the existing line of credit will also be used.

     During 1989, a bank subsidiary was identified as a potentially responsible
     party (PRP) in connection with material claims asserted under the
     Comprehensive Environmental Response, Compensation and Liability Act and
     corresponding state environmental laws.  On December 30, 1992 the bank
     subsidiary was fully and unconditionally released from all claims under
     Federal and State laws and from future liability relating to the claims.

     In the normal course of their business, the Company and its subsidiary
     banks are named or threatened to be named as defendants in various other
     lawsuits, some of which involve claims for substantial amounts of punitive
     damages.  With respect to each of these other suits it is the opinion of
     management, following consultation with legal counsel, that these suits are
     without merit or in the event the plaintiff prevails, the ultimate
     liability or disposition thereof will not have a material adverse effect on
     the consolidated financial condition of the Company.

(14) Rental Obligations
     ------------------

     Certain subsidiaries lease premises and equipment from unrelated parties. 
     The terms of certain leases are from one to three years and in most cases
     are cancelable at the option of either party with appropriate written
     notice.  The leases generally contain no options to renew and no purchase
     options upon expiration of the lease.  Rental expense aggregated
     approximately $649,000 in 1992, $641,000 in 1991, and $616,000 in 1990. 
     Under agreements existing at December 31, 1992, required annual rentals are
     approximately $279,000 in 1993, $240,000 in 1994 and $111,000 in 1995.

(15) Financial Instruments With Off-Balance-Sheet Risk
     -------------------------------------------------

     The Company is a party to financial instruments with off-balance-sheet risk
     in the normal course of business to meet the financing needs of its
     customers and to reduce its own exposure to fluctuations in interest rates.
     These financial instruments include commitments to extend credit, standby
     letters of credit and interest swaps and collars.  These instruments
     involve, to varying degrees, elements of credit and interest rate risk in
     excess of amounts recognized in the consolidated balance sheet.

     Commitments to extend credit are agreements to lend to a customer as long
     as there is no violation of any condition established in the contract. 
     Commitments generally have fixed expiration dates or other termination
     clauses and may require payment of a fee.  Since many of the commitments
     are expected to expire without being drawn upon, the total commitment
     amounts do not necessarily represent future cash requirements.  The Company
     evaluates each customer's creditworthiness on a case-by-case basis.  The
     amount of collateral obtained if deemed necessary by the Company upon
     extension of credit is based on management's credit evaluation of the
     customer.  Collateral held varies but may include accounts receivable,
     inventory, property, plant, and equipment, and income-producing commercial
     properties.

     Standby letters of credit and financial guarantees written are conditional
     commitments issued by the Company to guarantee the performance of a
     customer to a third party.  Most commitments extend for no more than 2
     years.  The credit risk involved in issuing letters of credit is
     essentially the same as that involved in extending loan facilities to
     customers.  The Company holds various collateral supporting those
     commitments for which collateral is deemed necessary.  The Company uses the
     same credit policies in making commitments and conditional obligations as
     it does for on-balance-sheet instruments.

     The Company's exposure to credit loss in the event of nonperformance by the
     other party to the financial instrument for commitments to extend credit
     and standby letters of credit is represented by the contractual amount of
     those instruments.  The Company uses the same credit policies in making
     commitments and conditional obligations as it does for on-balance-sheet
     instruments.  At December 31, 1992, stand-by letters of credit in the
     amount of $1,320,000 were outstanding.  Commitments to extend credit to
     existing and new borrowers approximated $27,638,000 at December 31, 1992.

     Effective January 10, 1992, the Company entered into an interest rate swap
     agreement (the swap) to hedge its exposure to interest rate risk on
     adjustable rate debt.  The swap is an agreement to exchange interest
     payment streams based on a notional principal amount.  The swap has a
     notional principal amount of $5,000,000 and terminates January 10, 1995. 
     Revenues and expenses resulting from the swap are recognized as  components
     of interest revenue or expense over the life of the swap.  The Company
     recorded additional interest expense of $102,274 in 1992 due to the net

     In 1989, the Company entered into an interest rate collar (Collar)
     agreement to hedge its exposure to interest rate risk on adjustable rate
     debt.  The Company paid interest on the $4,000,000 notional Collar
     principal when the prime interest rate fell below 9.0% and would have
     received interest if the prime rate rose above 11.5%.  The agreement
     terminated July 28, 1992.  The net rate differential paid or received on
     the Collar was recorded as an adjustment to interest expense on borrowed
     funds.  The Company recorded additional interest expense of $59,778 in 1992
     and $23,556 in 1991, due to net rate differentials in those years.  There
     was no net rate differential in 1990.  The notional amount of the Collar
     did not represent exposure to credit loss.  The Company controlled the
     credit risk of its interest rate collar agreement through limits and
     monitoring procedures.

(16) Regulatory Matters
     ------------------

     In January 1989, the Federal Reserve Board (FRB) and the Federal Deposit
     Insurance Corporation (FDIC) issued risk-based capital guidelines to more
     accurately consider the credit risk inherent in the assets and
     off-balance-sheet activities of a bank or bank holding company and their
     assessment of capital adequacy.

     Under the guidelines, total capital has been redefined as core capital and
     supplementary capital.  The Company's core capital consists primarily of
     stockholders' equity, while supplementary capital consists primarily of the
     allowance for loan losses (not to exceed 1.25% of risk weighted assets). 
     Under the guidelines, all goodwill is to be excluded from the components of
     core capital.  The definition of assets has also been modified to include
     items on and off the balance sheet, with each item being assigned a
     predefined credit "risk-weight".

     At December 31, 1992, the Company's total risk-based capital (core plus
     supplementary) and core capital ratios, calculated in accordance with the
     guidelines, were 10.13% and 9.27%, respectively.  In addition to the
     risk-based guidelines discussed above, the FRB and FDIC also established a
     leverage ratio defined as core capital as a percentage of average tangible
     assets.  The Bank's leverage ratio at December 31, 1992 was 5.41%.

     The Company's and the Bank's capital ratios exceed the highest capital
     category, which requires total risk-based capital of at least 10%, core
     capital of at least 6% and a leverage ratio of at least 5%.

     The Federal Deposit Insurance Corporation Improvement Act ("FDICIA"), which
     was enacted on December 19, 1991, substantially revises 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 agencies to
     implement differing levels of oversight depending on the institution's
     capital category, as defined in the regulations.  A depository
     institution's capital category will depend upon where its capital ratios
     are in relation to various relevant capital measures, which include the
     risk-based capital and leverage ratios.  The capital categories represent
     minimum standards that will generally be applied to all institutions. 
     However, the regulatory agencies may impose higher minimum standards on
     individual institutions or may downgrade an institution at the applicable
     agency's discretion.  FDICIA generally restricts 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 (less than 8% total
     risk-based capital or 4% core capital and leverage).
                                                                     (Continued)

                  Notes to Consolidated Financial Statements


     FDICIA directs that each federal banking agency prescribe standards that
     may affect FDIC insurance rates and the operations of banks and bank
     holding companies.  Because such standards have not yet been established,
     management is unable to assess their impact.

(17) Fair Value of Financial Instruments
     -----------------------------------

     Statement of Financial Accounting Standards No. 107, Disclosures About Fair
     Value of Financial Instruments (Statement 107), required that the Company
     disclose the estimated fair values of its financial instruments.  The
     methods and significant assumptions used to estimate fair values for the
     various financial instruments are set forth below.

       Cash and Cash Equivalents
       -------------------------

       Due to the liquid nature of the instruments, the carrying value of due
       from banks and federal funds sold approximates market value.

       Investment Securities
       ---------------------

       Fair values of investment securities are based on quoted market prices or
       dealer quotes.  If a quoted market price is not available, fair value is
       estimated using quoted market prices for similar securities.

       The following table represents the carrying value and estimated fair
       value of investment securities at December 31, 1992:

</TABLE>
 
       Loans
       -----

       Fair values are estimated for portfolios of loans with similar financial
       characteristics.  Loans are segregated by type such as commercial, real
       estate, and installment.  Each loan category is further segmented into
       fixed and adjustable rate interest terms and by performing and
       nonperforming categories.

       The fair value of performing fixed rate loans is calculated by
       discounting scheduled cash flows through estimated maturity using
       estimated market discount rates that reflect the credit and interest rate
       risk inherent in the loan category using the U.S. Treasury yield curve
       adjusted to bond equivalent yields. The estimate of maturity is based on
       the Company's historical experience with repayments for each loan
       classification, modified, as required, by an estimate of the effect of
       current economic and lending conditions.  For performing real estate
       loans, fair value is estimated by discounting contractual cash flows
       adjusted for prepayment estimates using discount rates based on secondary
       market sources.
                                                                     (Continued)

                  Notes to Consolidated Financial Statements


       The fair value of adjustable rate loans was considered to be the carrying
       value of these instruments due to the frequent repricing, provided there
       had been no change in credit quality since origination.  At December 31,
       1992, the carrying value of net loans was $241,989,120 and the estimated
       fair value of net loans was $250,912,000.

       Deposits and Securities Sold Under Repurchase Agreements
       --------------------------------------------------------

       The fair value of demand deposits, savings accounts, and securities sold
       under repurchase agreements is the amount payable on demand at the
       reporting date, due to the liquid nature of the instruments and the
       frequent repricing.

       The fair value of fixed-maturity certificates of deposit is estimated
       using external market rates currently offered for deposits of similar
       remaining maturities.

       Following are the carrying value and estimated fair value of deposits and
       securities sold under repurchase agreements at December 31, 1992:

       Other Borrowed Funds and Long-Term Debt
       ---------------------------------------

       The term note payable and line of credit borrowings bear interest at a
       floating market rate and, as such, the carrying amounts are deemed to
       reflect fair value.

       Commitments to Extend Credit and Standby Letters of Credit
       ----------------------------------------------------------

       The fair value of commitments to extend credit can be estimated using the
       fees currently charged to enter into similar agreements, taking into
       account the remaining terms of the agreements and the present
       creditworthiness of the counterparties.  It is not practicable to
       estimate fair value because sufficient records are not readily available
       to support estimates of fees which can be realized on these instruments.

       Loan fees for the year ended December 31, 1992, including fees charged
       for commitments to extend credit and standby letters of credit, were
       approximately $330,000, of which a significant portion related to real
       estate refinancing.
                                                                     (Continued)

       Limitations
       -----------

       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 the Bank's entire
       holdings of a particular instrument.  Because no market exists for a
       significant portion of the Bank's financial instruments, fair value
       estimates are based on judgments regarding comparable market interest
       rates, 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 that are
       not considered financial assets include property and equipment.  In
       addition, the tax effect of the difference between the fair value and
       carrying value of financial instruments can have a significant effect on
       fair value estimates and have not been considered in the estimates.

                          BANK OF MONTANA SYSTEM
             NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                          SEPTEMBER 30, 1993 AND 1992
- --------------------------------------------------------------------------------
 
(1)  Managements Opinion
 
The consolidated financial statements included herein include the accounts of
Bank of Montana System and its subsidiaries (collectively, the Company) and have
been prepared, without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission.  Certain information and footnote
disclosures normally included in the consolidated financial statements prepared
in accordance with generally accepted accounting principles have been condensed
or omitted pursuant to such rules and regulations.  Although the Company
believes that the disclosures are adequate to make the information presented not
misleading, it is suggested that these financial statements be read in
connection with the consolidated financial statements and the notes thereto
included in the Company's annual report to shareholders for the year ended
December 31, 1992.
 
In the opinion of the Company, the accompanying unaudited September 30, 1993 and
audited December 31, 1992 consolidated financial statements contain all
adjustments necessary to present fairly the Company's financial position, and
the results of its operations and its cash flows for the nine months ended
September 30, 1993 and 1992, and the results of operations for the three months
ended September 30, 1993 and 1992.
 
The results of operations for the nine months ended September 30, 1993 are not
necessarily indicative of the results to be expected for the full year.
 
(2)  Acquisition
 
On March 31, 1993, Bank of Montana System ("BMS") completed the acquisition of
Montana Bancsystem, Inc. ("MBI") and its subsidiary, Montana Bank, with twelve
branches located in Montana.  Under the terms of the merger agreement, BMS
purchased all of the outstanding common shares of MBI and 99.6% of the
outstanding shares of Montana Bank for cash.  The purchase price of $38,977,000
included $38,202,000 related to the purchase of MBI's common stock and $775,000
of direct acquisition costs.  The results of operations and financial position
of MBI and its subsidiary subsequent to its acquisition date have been included
in the Company's consolidated financial statements of September 30, 1993.
 
The Merger was recorded during the first quarter of 1993 by the parent using the
purchase method of accounting in accordance with APB No. 16.  At September 30,
1993, goodwill (net of accumulated amortization) recorded in connection with the
Merger, which represents the excess of the purchase price over the estimated
fair value of the identifiable net assets at the consummation of the Merger,
amounted to approximately $6,930,000.  The amount of goodwill is subject to
change as the refinement of purchase accounting adjustments is finalized.

The following Unaudited Pro Forma Combined Summary of Operations presents a pro
forma combined summary of operations of the Company and MBI and its
subsidiaries for the nine months ended September 30, 1993 and 1992.
 
The unaudited Pro Forma Combined Summary of Operations is presented as if the

Summary of Operations for the nine months ended September 30, 1993 combines the
Company's historical results of operations for the nine months ended September
30, 1993, which included combined operations from April 1, 1993 forward, and
MBI's results of operations for the period ended January 1, 1993 through March
31, 1993.  This combined historical summary of operations information was
adjusted for the amortization of purchase accounting adjustments, as well as for
the elimination of expenses that are not ongoing.  The unaudited Pro Forma
Combined Summary of Operations for the nine months ended September 30, 1992
combines the historical results of operations of the Company and MBI for the
nine months ended September 30, 1992, after giving effect to amortization of
purchase accounting adjustments and  the elimination of the expenses that are
not ongoing.  Certain amounts in MBI'S historical results of operations were
reclassified to conform to the Company's financial statement presentation.

The Unaudited Pro Forma Combined Summary of Operations data is intended for
informational purposes only and is not necessarily indicative of the future
results of operations of the Company, or of the results of operations that
would have actually occurred had the Merger been in effect for the full periods
presented.

                             PLAN OF REORGANIZATION



    AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") entered into as of
the 13th day of September, 1993, by and between BANK OF MONTANA SYSTEM ("BMS"),
a Montana 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 BMS (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 Capital Stock of BMS of the par value
of $2.50 per share ("BMS Common Stock") outstanding immediately prior to the
time the Merger becomes effective in accordance with the provisions of the
Merger Agreement (the "Effective Time of the Merger") 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 incorporated in Montana ("Merger Co.") will
be merged by statutory merger with and into BMS pursuant to the Merger
Agreement, with BMS as the surviving corporation, in which merger each share of
BMS 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 Norwest Common Stock determined by dividing the Adjusted Norwest
Shares (as defined below) by the number of shares of BMS Common Stock then
outstanding.  "Adjusted Norwest Shares" shall mean 4,200,000; provided, however,
that

          (i)  With respect to any severance or bonus agreements described in
     Schedule 4(b), the Adjusted Norwest Shares shall be reduced by a number
     equal to (A) $385,000 divided by (B) the Norwest Measurement Price (as
     defined below);

     above divided by (z) the Norwest Measurement Price (as defined below);

          (v) with respect to the Remediation (as defined in paragraph 4(aa) and
     the development and implementation of Remediation Plans (as defined in
     paragraph 4(aa)) required by paragraph 4(aa) (other than the costs of any

prices of a share of Norwest Common Stock as reported on the consolidated tape

the date hereof and the termination of such twenty trading day period, 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 stock dividend).

     "Losses" shall mean those amounts that the general ledger balancing and

represent valid timing differences and with respect to which, as of the date of
determination described in paragraph 1(a)(iv),  45 days has elapsed since the
date of origination of the related individual general ledger account entries, or
2) out of balance conditions including situations in which the entries in the

into a different number of shares or a different class of shares by reason of
any reclassification, recapitalization, split-up, combination, exchange of
shares or readjustment, or if a stock dividend thereon shall be declared with a
record date within such period, then the number of shares of Norwest Common
Stock into which a share of BMS Common Stock shall be converted pursuant to
subparagraph (a), above, will be appropriately and proportionately adjusted so

Norwest Common Stock as reported by the consolidated tape of the New York Stock
Exchange for each of the five (5) trading days immediately preceding the
Effective Time of the Merger.

     2.  REPRESENTATIONS AND WARRANTIES OF BMS.  BMS represents and warrants to
Norwest, as of the date of this Agreement (except as otherwise expressly
provided), as follows:

     (a)  Organization and Authority.  BMS is a corporation duly organized,
validly existing and in good standing under the laws of the State of Montana, is
duly qualified to do business and is in good standing in all jurisdictions where
(i) its ownership or leasing of property or the conduct of its business requires
it to be so qualified and (ii) failure to be so qualified would have a material
adverse effect on BMS and the "BMS Subsidiaries" (as hereinafter defined) taken
as a whole; and BMS has corporate power and authority to own its properties and
assets and to carry on its business as it is now being conducted.  BMS 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").  BMS has furnished
Norwest true and correct copies of its articles of incorporation and by-laws, as
amended.

     (b)  BMS's Subsidiaries.  Schedule 2(b) sets forth a complete and correct
list of all of BMS's subsidiaries as of the date hereof (individually a "BMS
Subsidiary" and collectively the "BMS Subsidiaries," provided that from and
after the consummation of the acquisition by BMS of Heritage Bank, if such
acquisition is consummated, the term "BMS Subsidiary" shall be deemed to include
Heritage

Bank), 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 BMS. No equity
security of any BMS 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 BMS 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, nor are there
any stock appreciation, phantom stock or similar rights outstanding.  Subject to
12 U.S.C. (S) 55 (1982) and except as set forth on Schedule 2(b), all of such
shares so owned by BMS 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 BMS Subsidiary is a corporation or state 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), BMS 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 BMS consists of
4,000,000 shares of capital stock, $2.50 par value, of which, as of the close of
business on March 31, 1993, 2,016,353 shares were outstanding and no shares were
held in the treasury.  All of the outstanding shares of capital stock of BMS
have been duly and validly authorized and issued and are fully paid and
nonassessable.  Except as set forth in Schedule 2(c), there are no outstanding
subscriptions, contracts, conversion privileges, options, warrants, calls or
other rights obligating BMS to issue, sell or otherwise dispose of, or to
purchase, redeem or otherwise acquire, any shares of capital stock of BMS, nor
are there any stock appreciation, phantom stock or similar rights outstanding.
Except as set forth on Schedule 2(c), since March 31, 1993, no shares of BMS
capital stock have been purchased, redeemed or otherwise acquired, directly or
indirectly, by BMS or any BMS Subsidiary and no dividends or other distributions
have been declared, set aside, made or paid to the shareholders of BMS.  The
maximum number of shares of BMS Common Stock (assuming for this purpose that
phantom shares and other share-equivalents constitute BMS 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 2,014,676.

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

     Except as set forth on Schedule 2(d), neither the execution, delivery and
performance by BMS of this Agreement or the Merger Agreement, nor the
consummation of the transactions contemplated hereby and thereby, nor compliance
by BMS 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 BMS or any BMS Subsidiary under any of the terms,
conditions or provisions of (x) its articles of incorporation or by-laws or (y),
except to the extent that such violation, conflict, breach, default, termination
acceleration or lien could not reasonably be expected to have a material adverse
effect on the business, financial condition or results of operations of BMS and
the BMS Subsidiaries taken as a whole, any note, bond, mortgage, indenture, deed
of trust, license, lease, agreement or other instrument or obligation to which
BMS or any BMS Subsidiary is a party or by which it may be bound, or to which
BMS or any BMS Subsidiary or any of the properties or assets of BMS or any BMS
Subsidiary may be subject, or (ii) subject to compliance with the statutes and
regulations referred to in the next paragraph, violate any statute, rule or
regulation or, to the best knowledge of BMS, violate any judgment, ruling,
order, writ, injunction, or decree applicable to BMS or any BMS Subsidiary or
any of their respective properties or assets.

Act"), the Securities Exchange Act of 1934 and the rules and regulations
thereunder (the "Exchange Act"), the securities, banking, insurance or blue sky

     director, employee or consultant (other than those which are terminable at
     will by BMS or such BMS Subsidiary);

          (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 BMS or any BMS 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, BMS or
     any BMS Subsidiary may carry on its business (other than as may be required
     by law or applicable regulatory authorities);

          (v) any contract not made in the ordinary course of business which is

     (k)  Litigation and Other Proceedings.  BMS has furnished Norwest copies of

Subsidiary since such date.  Except as set forth on Schedule 2(k), there is no
pending or, to the best knowledge of BMS, threatened claim, action, suit,
investigation or proceeding against BMS or any BMS Subsidiary, nor is BMS or any
BMS Subsidiary 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 BMS and the BMS Subsidiaries taken as a whole.

     (l)  Insurance.  BMS and each BMS Subsidiary is presently insured, and
during each of the past five calendar years (or during such lesser period of
time as BMS has owned such BMS Subsidiary) has been insured, for reasonable
amounts with financially sound and reputable insurance companies against such
risks as companies engaged in a similar business would, in accordance with good
business practice, customarily be insured and has maintained all insurance
required by applicable law and regulation.

     (m)  Compliance with Laws.  BMS and each BMS 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 both (i) 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 (ii) that are material to the business of BMS and the
BMS Subsidiaries, taken as a whole; all such permits, licenses, certificates of
authority, orders and approvals are in full force and effect and, to the best
knowledge of BMS, no suspension or cancellation of any of them is threatened;
and all such filings, applications and registrations are current.  Except as set
forth on Schedule 2(m), the conduct by BMS and each BMS Subsidiary of its
business and the condition and use of its properties does not violate or
infringe any applicable domestic (federal, state or local) or foreign law,
statute, ordinance, license or regulation, including without limitation the
Americans With Disabilities Act, except where such violation or infringement
could not reasonably be expected to have a material adverse effect on the
business, financial condition or results of operations of BMS and the BMS
Subsidiaries taken as a whole; provided, however, that the representations and
warranties included in this sentence shall be limited to matters not relating to
environmental laws and regulations, as to which BMS makes only the

                                      A-10
<PAGE>

representations and warranties set forth in paragraph 3(v).  Neither BMS nor any
BMS Subsidiary is in default under any order, license 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 where such default could not
reasonably be expected to have a material adverse effect on the business,
financial condition or results of operations of BMS and the BMS Subsidiaries,
taken as a whole.  Except for statutory or regulatory restrictions of general
application and except as set forth on Schedule 2(m), no federal, state,
municipal or other governmental authority has placed any restriction on the
business or properties of BMS or any BMS Subsidiary which reasonably could be
expected to have a material adverse effect on the business or properties of BMS
and the BMS Subsidiaries taken as a whole.

     (n)  Labor.  No work stoppage involving BMS or any BMS Subsidiary is
pending or, to the best knowledge of BMS, threatened.  Neither BMS nor any BMS
Subsidiary is involved in, or threatened with or affected by, any labor dispute,
arbitration, lawsuit or administrative proceeding which could reasonably be
expected to materially and adversely affect the business of BMS and the BMS
Subsidiaries, taken as a whole.  Employees of BMS and the BMS Subsidiaries are
not represented by any labor union nor are any collective bargaining agreements
otherwise in effect with respect to such employees.

     (o)  Material Interests of Certain Persons.  Except as set forth on
Schedule 2(o), to the best knowledge of BMS, no officer or director of BMS or
any BMS Subsidiary, or any Associate (as hereinafter defined) of any such
officers or directors, has any interest in any material contract or property
(real or personal), tangible or intangible, used in or pertaining to the
business of BMS or any BMS Subsidiary.  For purposes of this paragraph 2(o), the
term "Associate" means (i) any corporation or organization (other than BMS or
any BMS Subsidiary) of which any officer or director of BMS or any BMS
Subsidiary, is an officer or partner or is, directly or indirectly, the
beneficial owner of 10 percent or more of any class of equity securities, (ii)
any trust or other estate in which any such officer or director has a
substantial beneficial interest or as to which any such officer or director
serves as trustee or in a similar fiduciary capacity, and (iii) any relative or
spouse of any such officer or director, or any relative of such spouse, who has
the same home as any such officer or director, or who is a director or officer
of BMS or any BMS Subsidiaries.

     Schedule 2(o) sets forth a correct and complete list of all loans from BMS
or any BMS Subsidiary to any present officer, director, employee or any
Associate or "related interest" (as defined in Regulation O of the Federal
Reserve Board) of any such person which was required under Regulation O of the

     (p)  BMS 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 BMS or any BMS Subsidiary acts as the plan sponsor as
     defined in ERISA Section 3(16)(B), and with respect to which any liability
     under ERISA or otherwise exists or may be incurred by BMS or any BMS
     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), BMS or the BMS 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.  BMS
     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 of the end of the most recent Plan year, exceed the value of
     the assets of the Plan allocable to such vested or accrued benefits.

          (iv) Except as set forth in Schedule 2(p), and to the best knowledge
     of BMS, 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 BMS, 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 BMS
     and the BMS Subsidiaries taken as a whole.

          (v) Except as set forth on Schedule 2(p), no Plan which is subject to
     Title IV of ERISA or any trust created thereunder has been terminated, nor 
     

                                      A-12
<PAGE>

     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 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 BMS or any BMS 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 BMS and the BMS
 Subsidiaries supplied or to be supplied by BMS 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 BMS Common Stock pursuant to the provisions of the Merger Agreement
(together with all amendments and supplements thereto, the "Registration
Statement"), (ii) the prospectus-proxy statement to be included in such
Registration Statement relating to (x) the shares of Norwest Common Stock to be
delivered to the shareholders of BMS pursuant to the Merger Agreement and (y)
the holding of a special meeting of the shareholders to consider and vote on the
Merger, and to be mailed to BMS's shareholders in connection with such meeting
(the "Prospectus-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 Prospectus-Proxy Statement, when mailed, contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements contained therein, in light of the
circumstances under which they are made, not misleading or, in the case of the
Prospectus-Proxy Statement or any amendment thereof or supplement thereto, at
the time of the meeting of shareholders referred to in paragraph 4(c), or at the
Effective Time of the Merger, contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statement contained therein, in light of the circumstances under which they
are made, not misleading or omit to state a material fact necessary to correct
any statement in any earlier communication with 

                                      A-13
<PAGE>

respect to the solicitation of any proxy for such meeting.  All documents which
BMS and the BMS 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
BMS nor any BMS 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 BMS
nor any BMS 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 BMS or any BMS Subsidiary
in connection with this Agreement and the Merger Agreement or the transactions
contemplated hereby and thereby.

  (t)  Administration of Trust Accounts.  BMS and each BMS Subsidiary has
properly administered in all respects material, and which could reasonably be
expected to be material, to the financial condition of BMS and the BMS
Subsidiaries taken as a whole all accounts for which it acts as a fiduciary
(excluding IRA Custodial Accounts invested solely in bank insured deposits),
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 and all such accounts are listed on
Schedule 2(t).  Neither BMS, any BMS Subsidiary, nor any director, officer or
employee of BMS or any BMS Subsidiary has committed any breach of trust with
respect to any such fiduciary account which is material to, or could reasonably
be expected to be material to, the financial condition of BMS and the BMS
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.  There have been no indemnity claims made
pursuant to the Stock Acquisition Agreement, dated as of June 16, 1986, between
DADCO Incorporated and BMS.

  (u)  No Defaults.  Except as set forth on Schedule 2(u), neither BMS nor any
BMS 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
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 BMS and the BMS Subsidiaries, taken as a whole.  To
the best of BMS's knowledge, all parties with whom BMS or any BMS Subsidiary has

                                      A-14
<PAGE>

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

  (v)  Environmental Liability.  Except as set forth on Schedule 2(v), 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 BMS or any BMS Subsidiary, any liability arising from the
violation of or obligation under any local, state or federal environmental
statute, regulation or ordinance pending or to the best of BMS's knowledge,
threatened against BMS or any BMS Subsidiary the result of which has had or
could reasonably be expected to have a material adverse effect upon BMS and the
BMS Subsidiaries taken as a whole.   Except for the remediation described in
paragraph 4(aa), to the best of BMS's knowledge there is no reasonable basis for
any such proceeding, claim or action.  To the best of BMS's knowledge neither
BMS nor any BMS 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.

  3.  REPRESENTATIONS AND WARRANTIES OF NORWEST.  Norwest represents and
warrants to BMS, as of the date of this Agreement (except as otherwise expressly
provided), 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 (i) its ownership or leasing of property or the conduct of its business
requires it to be so qualified and (ii) failure to be so qualified would have a
material adverse effect on Norwest and its subsidiaries taken as a whole, and
Norwest has corporate power and authority to own its properties and assets and
to carry on its business as it is now being conducted.  Norwest is registered as
a bank holding company with the Federal Reserve Board under the BHC Act.

  (b)  Norwest Subsidiaries.  Schedule 3(b) sets forth a complete and correct
list as of December 31, 1992, 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 

                                      A-15
<PAGE>

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 June 30, 1993, 1,132,750 shares of 10.24% Cumulative
Preferred Stock at $100 stated value and 1,143,750 shares of Cumulative
Convertible Preferred Stock, Series B, at $200 stated value were outstanding,
and (ii) 500,000,000 shares of Common Stock, $1-2/3 par value, of which as of
the close of business on June 30, 1993, 290,811,725 shares were outstanding and
2,287,743 shares were held in the treasury.

  (d)  Authorization.  Norwest has the corporate power and authority to enter
into this Agreement and to carry out its obligations hereunder.  The execution,
delivery and performance of this Agreement by Norwest and the consummation of
the transactions contemplated hereby have been duly authorized by the Board of
Directors of Norwest.  No approval or consent by the stockholders of Norwest is
necessary for the execution and delivery of this Agreement and the 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) 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), except to the extent
that such violation, conflict, breach, default, termination, acceleration or
lien could not 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, any note, bond, mortgage, indenture, deed of
trust, license, lease, agreement or other instrument or  

                                      A-16
<PAGE>

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, violate any statute, rule or regulation or, to the best
knowledge of Norwest, violate any judgment, ruling, order, writ, injunction or
decree 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, banking, insurance or blue sky
laws of the various states, filings, consents, reviews, authorizations,
approvals or exemptions required under the BHC Act or the HSR Act, and filings
required to effect the Merger under Montana 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 statements of financial
condition of Norwest and Norwest's subsidiaries as of December 31, 1992 and 1991
and related consolidated statements of income, stockholders' equity and cash
flows for the three years ended December 31, 1992, 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, 1992, as amended by Form 8
dated March 3, 1993 (the "Norwest 10-K"), as filed with the SEC, and the
unaudited consolidated balance sheets of Norwest and its subsidiaries as of
June 30, 1993 and the related unaudited consolidated statements of income and
cash flows for the six months then ended included in Norwest's Quarterly Report
on Form 10-Q for the fiscal quarter ended June 30, 1993, 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, each of Norwest and the Norwest
Subsidiaries 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 

                                      A-17
<PAGE>

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 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 timely filed with the SEC all reports, statements and
forms required to be filed pursuant to the Exchange Act.

  (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 June 30, 1993, 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 that
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.  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 or related 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.  To the knowledge of
Norwest, no issue has been raised by any federal, state, local or foreign taxing
authority in connection with an audit or examination 

                                      A-18
<PAGE>

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 June 30, 1993, there has been no
change in the business, financial condition or results of operations of Norwest
or any Norwest Subsidiary which has had, or may reasonably be expected to have,
a material adverse effect on the business, financial condition or results of
operations of Norwest and its subsidiaries taken as a whole (other than changes
in banking laws or regulations, changes in generally accepted accounting
principles or interpretations thereof that affect the banking industry
generally, or changes in general economic conditions that uniformly affect the
banking industry on a nationwide basis, including changes in the general level
of interest rates).

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

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

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

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

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

  (l)  Insurance.  Norwest and each Norwest Subsidiary is presently insured, and
 during each of the past five calendar years (or during such lesser period of
time as Norwest has owned such Norwest Subsidiary) has been insured or self-
insured, for reasonable amounts with financially sound and reputable insurance
companies 

                                      A-19
<PAGE>

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 both (i) 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 (ii) that are material to the business of Norwest and
its Subsidiaries, taken as a whole; 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 any applicable
domestic (federal, state or local) or foreign law, statute, ordinance, license
or regulation, including without limitation the American With Disabilities Act,
except where such violation or infringement could not reasonably be expected to
have a material adverse effect on the business, financial condition or results
of operation of Norwest and its subsidiaries taken as a whole.  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 where such
default could not 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.  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
reasonably be expected to  materially and adversely affect the business of
Norwest and the Norwest Subsidiaries, taken as a whole.  Except as set forth on
Schedule 3(j), employees of Norwest and the Norwest Subsidiaries are not
represented by any labor union nor are any collective bargaining agreements
otherwise in effect with respect to such employees.

 (o)  Norwest Benefit Plans.

       (i) As of the date hereof, the only "employee benefit plans" within the
     meaning of Section 3(3) of ERISA for which Norwest or any Norwest

                                      A-20
<PAGE>

     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 of the end of the most recent Plan year, exceed the value of
     the assets of the Norwest Plans allocable to such vested or accrued
     benefits.

       (iv) Except as set forth on Schedule 3(o), 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.

                                      A-21
<PAGE>

       (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 Prospectus-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 Prospectus-Proxy Statement, when
mailed, contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
contained therein, in light of the circumstances under which they are made not
misleading or, in the case of the Prospectus-Proxy Statement or any amendment
thereof or supplement thereto, at the time of the meeting of shareholders
referred to in paragraph 4(c), or at the Effective Time of the Merger, contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements contained
therein,  in light of the circumstances under which they are made, not
misleading, or omit to state a material fact necessary to correct any statement
in any earlier communication with respect to the solicitation of any proxy for
such meeting.  All documents which 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 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

                                      A-22
<PAGE>

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 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 arising from any violation of or obligation 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 its jurisdiction of incorporation, and will have corporate
power and authority to own or lease its properties and assets and to carry on
its business.

 (u)  Current Plans or Intentions.

          the surviving corporation,

               (D)  merge any BMS Subsidiary with or into another corporation,
          except if such BMS Subsidiary is the surviving corporation, if such
          merger is with BMS or another BMS Subsidiary, or if such merger were a
          sale of assets described in clause (E) below, it would not result in a
          violation of the "substantially all" test described in such clause
          (E),

               (E) cause BMS or any BMS Subsidiary to sell or otherwise dispose
          of any of its assets to any entity other than BMS or a BMS Subsidiary,
          with the following exceptions (A) sales or dispositions in the
          ordinary course of business or (B) sales or dispositions which would
          not violate the "substantially all" test as defined in Rev. Proc. 77-
          37, 1977-2 C.B. 568 Section 3.01.

     Norwest hereby agree that any such transactions shall not be deemed a
     breach of this paragraph 3(u):


               (A)  the Escrow Business (as defined in paragraph 4(v)), and

               (B)  the branch banks described in paragraph 7(e).

and will cooperate with Norwest in the preparation of, the Registration
Statement and Prospectus-Proxy Statement referred to in paragraph 2(q) hereof
(including audited financial statements, prepared in accordance with generally
accepted accounting principles, in form suitable for inclusion in the
Registration Statement and Prospectus-Proxy Statement), or any statement or

any material respect and to provide the information needed to correct such
inaccuracy or omission.

     (e)  BMS will promptly take all necessary corporate and other action and
use its best efforts to obtain all approvals of regulatory authorities, consents
and 

                                      A-26
<PAGE>

other approvals required of BMS to carry out the transactions contemplated by

Agreement, with the same undertaking from such professional advisers.  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 BMS, in the public domain, or later acquired by
BMS 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 BMS, nor any BMS Subsidiary, nor any director, officer,
representative or agent thereof, will, directly or indirectly, solicit,
authorize the solicitation of or enter into any discussions with or execute any
agreement in principle or definitive agreement with any corporation,
partnership, person or other entity or group (other than Norwest or its

shares of common stock, any option or warrant to purchase any shares of common

inquiry to BMS or any BMS Subsidiary concerning any of the foregoing, BMS or
such BMS Subsidiary will promptly disclose such offer or inquiry, including the
terms thereof, to Norwest.

     (i)  BMS shall consult with Norwest as to the form and substance of any
proposed press release or other proposed public disclosure of matters related to

arrangements as of the Effective Date of the Merger, (ii) to amend the Plans to

                                      A-27
<PAGE>

comply with the provisions of the TRA and regulations thereunder and other
applicable law as of the Effective Date of the Merger, and (iii) to submit

such applications prior to the Effective Date of the Merger.

     (k)  From and after the date of this Agreement, neither BMS nor any BMS
Subsidiary shall take any action which, with respect to BMS, would disqualify
the Merger as a "pooling of interests" for accounting purposes; provided,
however, any action taken by BMS or any BMS Subsidiary pursuant to any request
by Norwest, including but not limited to under paragraph 4(j) or pursuant to a
specific requirement of this Agreement shall not constitute a breach of this
paragraph 4(k).

     (l)  BMS shall use its best efforts to obtain and deliver to Norwest, at
least 32 days prior to the Effective Date of the Merger, signed representations
substantially in the form attached hereto as Exhibit B by each executive

"affiliate" of BMS within the meaning of such term as used in Rule 145 under the
Securities Act.

     (m) As of December 31, 1993, BMS shall establish such asset depreciation
schedules, fixed asset and credit loss reserves and such other additional
accruals and reserves as may be necessary to conform BMS's credit loss reserve
and other accounting practices and methods to those of Norwest and Norwest's
plans with respect to the conduct of BMS's business following the Merger and to
provide for the costs and expenses relating to the consummation by BMS of the
Merger and the other transactions contemplated by this Agreement.

     (n) BMS shall cause Montana Bank and Bank of Montana not to consummate the
merger of Montana Bank with and into Bank of Montana pursuant to the Agreement
and Plan of Merger, dated as of April 1, 1993, by and between Montana Bank and
Bank of Montana  or otherwise (the "Billings Merger").  BMS shall use its best
efforts to obtain extensions from the appropriate regulatory authorities,
including without limitation, the Federal Reserve Board and the Montana
Department of Commerce, to permit consummation of the Billings Merger at some
future date.

          (iii) BMS shall  promptly obtain the written consent of Heritage Bank

     sell, prior to the acquisition of Heritage Bank by Bank of Montana, any
     existing ownership interest in, the property located at 120 First Avenue
     North, Great Falls, Montana on such terms and conditions (including
     consideration to be paid) as BMS and Norwest shall mutually agree; and

          (v) the Heritage Acquisition Agreement shall be amended to eliminate

Subsidiary by the Montana Department of Health and Environmental Sciences, or
other applicable state or Federal governmental authority, to comply with
environmental laws and regulations.  BMS shall use its best efforts to present
Remediation Plans to the appropriate state authority and to obtain approval and
certification of the completion of any necessary Remediation.  In no event shall
this covenant require BMS to incur Net Costs in excess of $100,000 for
conducting such  Remediation or implementing Remediation Plans.

     (bb)  Except as otherwise permitted or required by this Agreement, from the
date hereof until the Effective Time of the Merger, neither BMS nor any BMS
Subsidiary shall (without the prior written consent of Norwest) declare, set
aside, make or pay any dividend or other distribution with respect to its
capital stock except as permitted pursuant to this paragraph (bb).  The Board of
Directors of BMS may declare, and BMS may pay to its shareholders of record,
regular quarterly cash dividends (i) with respect to the third calendar quarter
of 1993, in an amount not exceeding $0.41 per share of outstanding BMS Common
Stock (which amount was  declared on August 2, 1993 and paid on August 26, 1993)
and (ii) with respect to each approximately 91-day period from the last payment
date of the BMS regular quarterly cash dividend (The "91-day Period") in which
the Effective Date does not occur, in an amount not exceeding $0.42 per share of
outstanding BMS Common Stock.  With respect to the 91-day Period in which the
Effective Date does occur, (A) if the Effective Date occurs on or before the
record date for dividends on Norwest Common Stock for such quarter, the Board of
Directors of BMS may declare, and BMS may pay to its shareholders of record, a
quarterly cash dividend (the record date for which may be the Effective Date) in
an amount equal to (I) $846,164 minus (II) the aggregate dividends declared and
paid by Norwest with respect to 4,200,000 shares of Norwest common stock in the
immediately preceding calendar quarter multiplied by (III) a fraction the
numerator of which is the number of days from and including the date of the
immediately preceding dividend payment made to BMS shareholders through but
excluding the Effective Date and the denominator of which is 91, and (B) if the
Effective Date occurs after the record date for dividends on Norwest Common
Stock for such quarter and before the next BMS dividend payment date, the Board
of Directors of BMS may declare, and BMS may pay to its shareholders of record,
a quarterly cash dividend in an amount not exceeding $0.42 per share of
outstanding BMS Common Stock.  Any of the Boards of Directors of the BMS
Subsidiaries may declare, and any such BMS Subsidiary may pay, any regular
dividend in accordance with applicable law and regulation.  BMS shall cause its
dividend record and payment dates to coincide with the Norwest dividend record
and payment dates.

advise BMS if at any time prior to the Effective Date of the Merger, any
information provided by Norwest in the Prospectus-Proxy Statement becomes
incorrect or incomplete in any material respect and to provide the information
needed to correct such inaccuracy or omission.

     (c)  As promptly as practicable after the execution of this Agreement,
Norwest will file with the SEC the Registration Statement under the Securities
Act and any other applicable documents, which will include the  Prospectus-Proxy
Statement, and will use its best efforts to cause the Registration Statement to
become effective under the Securities Act and applicable state securities laws
as soon as practicable.  Norwest shall advise BMS promptly when the Registration
Statement has become effective and of any supplements or amendments thereto, and
Norwest shall furnish BMS with copies of all such documents.  At the time the
Registration Statement becomes effective, the Registration Statement and the
Prospectus-Proxy Statement will comply in all material respects with the
provisions of the Securities Act and the published rules and regulations
thereunder, and will not contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the

                                      A-33
<PAGE>

that none of the provisions of this subparagraph shall apply to statements in or
omissions from the Registration Statement or the Prospectus-Proxy Statement made
in reliance upon and in conformity with information furnished by BMS or any BMS
Subsidiary for use in the Registration Statement or the Prospectus-Proxy
Statement. Norwest shall bear the costs of all SEC filing fees with respect to
the Registration Statement and the costs of qualifying the shares of Norwest
Common Stock under state blue sky laws as necessary.

     (d)  Norwest will file all documents required to be filed to list the
Norwest Common Stock to be issued pursuant to the Merger Agreement on the New
York Stock Exchange and the Chicago Stock Exchange and use its best efforts to
effect said listings.

     (e)  The shares of Norwest Common Stock to be issued by Norwest to the
shareholders of BMS pursuant to this Agreement and the Merger Agreement will,
upon such issuance and delivery to said shareholders pursuant to the Merger
Agreement, be duly authorized, validly issued, fully paid and nonassessable.
The shares of Norwest Common Stock to be delivered to the shareholders of BMS
pursuant to the Merger Agreement are and will be free of any preemptive rights
of the stockholders of Norwest.

     (f)  Norwest will file all documents required to obtain prior to the
Effective Time of the Merger all necessary Blue Sky permits and approvals, if
any, required to carry out the transactions contemplated by this Agreement, will
pay all expenses incident thereto and will use its best efforts to obtain such
permits and approvals.

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

     (h)  Norwest will hold in confidence all documents and information
concerning BMS and BMS'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.  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 BMS (except to the extent that such information can be shown to
be previously known to Norwest, in the public domain, or later acquired by
Norwest from other legitimate sources) and, upon request,  all such documents,
copies thereof or extracts therefrom shall immediately thereafter be returned to
BMS.

                                      A-34

connection with the Merger under the Montana Business Corporation Act.

     (j)  Norwest will use its best efforts to deliver to the Closing all
opinions, certificates and other documents required to be delivered by it at the
Closing.

     (k)  Norwest shall consult with BMS 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.

     (l)  Norwest shall promptly give BMS written notice of receipt of the
regulatory approvals referred to in paragraph 7(e).

     (m)  Norwest shall use its best efforts to obtain and deliver to BMS, at
least 32 days prior to the Effective Date of the Merger, signed representations
from the directors and executive officers of Norwest to the effect that they
will not sell shares of Norwest or BMS during the period commencing 30 days
prior to the Effective Date and ending upon publication by Norwest of financial
results including at least 30 days of combined operations of BMS and Norwest.

     (n)  For a period not exceeding fifteen days prior to the Closing Date,
Norwest will permit BMS and its representatives to examine its books, records
and properties and interview officers, employees and agents of Norwest at all
reasonable times when it is open for business.  No such examination by BMS or
its representatives shall in any way affect, diminish or terminate any of the
representations, warranties or covenants of Norwest herein expressed.

     (o)  Norwest shall continue to file all reports and data with the SEC
necessary to permit the shareholders of BMS who may be deemed "underwriters'
(within the meaning of Rule 145 under the Securities Act) of BMS Common Stock to
sell the Norwest Common Stock received by them in connection with the Merger
pursuant to Rules 144 and 145(d) under the Securities Act if they would
otherwise be so entitled.  After the Effective Date, Norwest will file with the
SEC reports, statements, and other materials required by the federal securities
laws on a timely basis.

     (p)  For three years following the Effective Time of the Merger, Norwest
shall maintain directors' and officers' liability insurance with respect to
future claims arising from facts or events that occurred before the Effective
Time of the Merger, which insurance shall contain terms and conditions
(including the amount of such coverage, amount of any deductibles and exclusions
thereunder) no less favorable than the policies currently maintained by BMS
(except that such policy shall not cover employees who are not officers or
directors of BMS).  Norwest shall insure that all rights to indemnification and
all limitations of liability existing in favor  of any person who is now, or has
been at any time prior to the date 

                                      A-35
<PAGE>

hereof, or who becomes prior to the Effective Time of the Merger, a director,
officer, employee, fiduciary or agent of BMS or any BMS Subsidiary (the
"Indemnified Parties") in BMS's Articles of Incorporation and By-laws or similar
governing documents of any BMS Subsidiary, as in effect on the date hereof, or
allowed under applicable law as in effect on the date hereof, shall, with
respect to claims arising from facts or events that occurred before the
Effective Time of the Merger, survive the Merger and shall continue in full
force and effect, without any amendment, for a period of not less than three
years from the Effective Time of the Merger; provided, however, that all rights
to indemnification in respect of any claim asserted or made within such period
shall continue until the final disposition of such claim. Nothing contained in
this paragraph 5(p) shall be deemed to preclude the liquidation, consolidation
or merger of BMS or any BMS Subsidiary in a manner consistent with the
provisions of paragraph 5(t), in which case all of such rights to
indemnification and limitations on liability shall be deemed to so survive and
continue notwithstanding any such liquidation, consolidation or merger;
provided, however, that in the event of a liquidation or sale of substantially 
all of the assets of BMS, Norwest shall guarantee, to the extent of the net
asset value of BMS as of the Effective Date, the indemnification obligations of
BMS to the extent provided by law.  Notwithstanding anything to the contrary
contained in this paragraph 5(p), nothing contained herein shall require Norwest
to indemnify any person who was a director or officer of a corporation, banking
institution or other entity acquired by BMS or any BMS 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 BMS
or any BMS Subsidiary is, as of the date of this Agreement, required to
indemnify any such person.  This paragraph is intended for the benefit of and
shall be enforceable by each Indemnified Party and each Indemnified Party's
heirs and representatives.

     (q)  Norwest agrees to assist BMS in the preparation of the schedules,
accruals and reserves described in paragraph 4(m) and in the calculation of the
net tax basis and the tax basis described in paragraph 7(p).

     (r)  Norwest shall use its best efforts to comply with any condition or
requirement of the Federal Reserve Board approval of the transactions
contemplated by this Agreement and the Merger Agreement that Norwest sell one or
more of (i) the Bank of Montana branch bank located in Lewistown, Montana (ii)
the Bank of Montana branch bank located in Anaconda, Montana and (iii) one, but
not both of, the Montana Bank and Bank of Montana branch banks located in Butte,
Montana; provided, however, that the terms and conditions of such sales shall be
acceptable to Norwest in its sole discretion.

     (s) Immediately prior to the Effective Time of the Merger, Norwest shall
loan to BMS funds sufficient to enable BMS to pay in full all of its
indebtedness to Norwest Bank Minnesota, N.A.

                                      A-36
<PAGE>

     (t)  (i)  Consistent with the representation made in paragraph 3(u), except
     as provided in clause (ii) below, Norwest shall not take any of the
     following actions within the twelve month period immediately following the
     Effective Date:

               (A)  liquidate BMS,

               (B)  liquidate any BMS Subsidiary, except if the assets of such
          BMS Subsidiary are distributed to BMS or another BMS Subsidiary,

               (C)  merge BMS with or into another corporation, except if BMS is
          the surviving corporation,

               (D)  merge any BMS Subsidiary with or into another corporation,
          except if such BMS Subsidiary is the surviving corporation, if such
          merger is with BMS or another BMS Subsidiary, or if such merger were a
          sale of assets described in clause (E) below, it would not result in a
          violation of the "substantially all" test described in such clause
          (E),

               (E) cause BMS or any BMS Subsidiary to sell or otherwise dispose
          of any of its assets to any entity other than BMS or a BMS Subsidiary,
          with the following exceptions (A) sales or dispositions in the
          ordinary course of business or (B) sales or dispositions which would
          not violate the "substantially all" test as defined in Rev. Proc. 77-
          37, 1977-2 C.B. 568 Section 3.01.

For purposes of this paragraph 5(t), the term "BMS Subsidiary" shall mean any
entity  with respect to which BMS or another BMS Subsidiary (so defined), at the
time of the occurrence of the event described in this paragraph 5(t), owns stock
that possesses at least 80% of the total voting power of such entity and has a
value equal to at least 80% of the total value of the stock of such entity.

          (ii)  Norwest may, for business or regulatory reasons, sell the
     following, whether as a sale of assets or stock or by merger, and BMS and
     Norwest hereby agree that any such transactions shall not be deemed a
     breach of this paragraph 3(a).


               (A)  the Escrow Business (as defined in paragrah 4(v)),

               (B)  the branch banks described in paragraph 7(e),

                                      A-37
<PAGE>


          (u)  Norwest shall have the right to conduct an environmental
investigation prior to Closing, including Phase I and Phase II assessments and
studies of the properties of BMS and the BMS Subsidiaries.  Norwest's
investigation shall be conducted by a competent environmental consultant
selected by Norwest.  Said environmental consultant shall be licensed, bonded
and insured in accordance with applicable laws and regulations.  Within seventy-
five (75) days after the date hereof, Norwest shall complete its investigation
and deliver to BMS, without cost, one legible, true, correct and complete copy
of each report produced as a result thereof and of all data and other
information delivered to Norwest in connection therewith.  Norwest will hold in
confidence such reports, data and other information with respect to such
environmental investigation in accordance with paragraph 5(h).  The rights
granted to Norwest shall be exercised at Norwest's sole risk.  Norwest agrees to
indemnify, defend and hold BMS harmless from any and all claims, causes of
actions, losses, liabilities, liens, demands, costs, expenses or damages
(including attorneys' fees and court costs) caused by Norwest or its
environmental consultants and arising in connection with Norwest's environmental
investigation.  Norwest's obligations pursuant to the immediately preceding
sentence shall survive any termination or cancellation of this Agreement.

          three-month periods ended June 30, 1993 and June 30, 1992, included in

          statements of Norwest and its consolidated subsidiaries at such later
          date and for such other periods as may be included in the Registration
          Statement) do not comply as to form in all material respects with the
          applicable accounting requirements of the Securities Act and the
          published rules and regulations thereunder, or such unaudited
          financial statements are not fairly presented in accordance with
          generally accepted accounting principles applied on a basis
          substantially consistent with that of the audited financial statements
          of Norwest and its consolidated subsidiaries included in the
          Registration Statement;

            (B) as of a specified date not more than five days prior to the date

          Norwest and its consolidated subsidiaries or any increases in the
          long-term debt of Norwest and its consolidated subsidiaries or any
          decreases in consolidated net assets or stockholders' equity of
          Norwest and its consolidated subsidiaries as of June 30, 1993 (or such
          later date) included in the Registration Statement, except in each
          case for changes, increases or decreases which the Registration

                                      A-40

          income, consolidated net interest income after provision for credit
          losses, consolidated income before income taxes, and consolidated net
          income and net income per share amounts of Norwest and its
          consolidated subsidiaries, in each case as compared with the
          comparable period of the preceding year, except in each case for
          changes, increases or decreases which the Registration Statement
          discloses have occurred or may occur or which are described in such
          letters;

       (iv) In addition to the examination referred to in their report or
     reports included in the Registration Statement and the limited procedures,
     inspection of minute books, inquiries and other procedures referred to in
     clause (iii) above, they have carried out certain specified procedures, not
     constituting an audit, with respect to certain amounts, percentages,
     numbers of shares and financial information which are derived from the
     general accounting records of Norwest and its consolidated subsidiaries,
     which appear in the Registration Statement under the certain captions to be
     specified by BMS, and have compared certain of such amounts, percentages,
     numbers and financial information with the accounting records of Norwest
     and its consolidated subsidiaries and have found them to be in agreement
     except as disclosed in such letters.

issued an order restraining, enjoining or otherwise prohibiting the consummation
of the transactions contemplated by this Agreement.

  (h)  From and after June 22, 1993, neither  BMS nor any BMS Subsidiary shall
have taken any action which, with respect to BMS, would disqualify the Merger as
a "pooling of interests" for accounting purposes; provided, however, any action
taken by BMS or any BMS Subsidiary pursuant to any request by Norwest, including
but not limited to under paragraph 4(j), or pursuant to a 

                                      A-42
<PAGE>

specific requirement of this Agreement shall not constitute a failure to satisfy
the conditions contained in this paragraph 7(h).  Norwest acknowledges that
except as set forth in the immediately preceding sentence, any other
disqualification of the Merger as a "pooling of interests" shall not constitute
a breach of paragraph 4(k) of this Agreement or a failure to satisfy the
condition to Norwest's obligations under this paragraph 7(h).

  (i)  At any time since the date hereof the total number of shares of BMS
Common Stock outstanding and subject to issuance upon exercise (assuming for

Common Stock) of all warrants, options, conversion rights, phantom shares or
other share-equivalents shall not have exceeded 2,014,676.

  (j)  The Registration Statement (as amended or supplemented) shall have become
effective under the Securities Act and shall not be subject to any stop order,
and no action, suit, proceeding or investigation by the SEC to suspend the
effectiveness of the Registration Statement shall have been initiated and be
continuing, or have been threatened or be unresolved.  Norwest shall have
received all state securities law or blue sky authorizations necessary to carry
out the transactions contemplated by this Agreement.

  (k)  Norwest shall have received from KPMG Peat Marwick a letter, dated as of
the effective date of the Registration Statement and updated through the date of
Closing, in form and substance satisfactory to Norwest, to the effect that:

       (i) they are independent public accountants with respect to BMS and the
     BMS Subsidiaries within the meaning of the Securities Act and the
     applicable published rules and regulations thereunder;

       (ii) in their opinion the financial statements of BMS and the BMS
     Subsidiaries examined by them and included in the Registration Statement
     comply as to form in all material respects with the applicable accounting
     requirements of the Securities Act and the published rules and regulations
     thereunder;

       (iii)  on the basis of limited procedures, not constituting an audit,
     including a reading of the unaudited financial statements referred to
     below, a reading of the latest available interim financial statements of
     BMS and the BMS Subsidiaries, inspection of the minute books of BMS and the
     BMS Subsidiaries since June 30, 1993; (or, if later, since the date of the
     most recent unaudited consolidated financial statements of BMS and the BMS
     Subsidiaries as may be included in the Registration Statement), inquiries
     of officials of BMS and the BMS Subsidiaries responsible for financial and
     accounting matters and such other inquiries and procedures as may be

                                      A-43
<PAGE>

     specified in such letter, nothing came to their attention that caused them
     to believe that:

            (A) the unaudited consolidated financial statements of BMS and the
          BMS Subsidiaries at June 30, 1993 and for the three month periods
          ended June 30, 1993 and June 30, 1992, included in the Registration
          Statement (or the unaudited consolidated financial statements of BMS
          and the BMS Subsidiaries at such later date and for such other periods
          as may be included in the Registration Statement) do not comply as to
          form in all material respects with the applicable accounting
          requirements of the Securities Act and the published rules and
          regulations thereunder, or such unaudited financial statements are not
          fairly presented in accordance with generally accepted accounting
          principles applied on a basis substantially consistent with that of
          the audited financial statements of BMS and the BMS Subsidiaries
          included in the Registration Statement;

            (B) as of a specified date not more than five days prior to the date
          of such letters, there have been any changes in the capital stock of
          BMS and the BMS Subsidiaries or any increases in the long-term debt of
          BMS and the BMS Subsidiaries or any decreases in consolidated net
          assets or stockholders' equity of BMS and the BMS Subsidiaries, in
          each case as compared with amounts shown in the balance sheet of BMS
          and the BMS Subsidiaries as of June 30, 1993 (or such later date)
          included in the Registration Statement, except in each case for
          changes, increases or decreases which the Registration Statement
          discloses have occurred or may occur or which are described in such
          letters;

            (C) for the period from June 30, 1993 (or such later date) to such
          specified date there were any decreases in consolidated net income,
          consolidated net income after provision for credit losses,
          consolidated income before income taxes, and consolidated net income
          and net income per share amounts of BMS and the BMS Subsidiaries, in
          each case as compared with the comparable period of the preceding
          year, except in each case for changes, increases or decreases which
          the Registration Statement discloses have occurred or may occur or
          which are described in such letters;

       (iv) in addition to the examination referred to in their report or
     reports included in the Registration Statement and the limited procedures,
     inspection of minute books, inquiries and other procedures referred to in
     clause (iii) above, they have carried out certain specified procedures, not
     constituting an audit, with respect to certain amounts, percentages,
     numbers 

                                      A-44
<PAGE>

     of shares and financial information which are derived from the general
     accounting records of BMS and the BMS Subsidiaries, which appear in the
     Registration Statement under the certain captions to be specified by
     Norwest, and have compared certain of such amounts, percentages, numbers
     and financial information with the accounting records of BMS and the BMS
     Subsidiaries and have found them to be in agreement except as disclosed in
     such letters.

  (l)  BMS and the BMS Subsidiaries, considered as a whole, shall not have
sustained since June 30, 1993 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.

  (m)  Except to the extent set forth on Schedule 2(v) and except for the

Subsidiary of, any liability arising from any violation of or obligation 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
BMS and the BMS Subsidiaries taken as a whole.  All  Remediation required
pursuant to paragraph 4(aa) shall have been completed prior to the Effective
Date; provided however, that if it is not practicable to complete such
Remediation using due diligence prior to the Effective Date, Remediation Plans
acceptable to Norwest shall have been developed and implemented.  In the event
that the Net Cost of the Remediation and the Remediation Plans exceeds $100,000,
Norwest shall not be obligated to close; provided, however, that if BMS elects
to reduce the purchase price as provided in paragraph 1(a)(v) by the full amount
of the Net Cost (including the amount by which the Net Cost exceeds $100,000),
then Norwest shall be obligated to close assuming that all other conditions to
closing have been satisfied or waived.  In the event that BMS does not elect to
reduce the purchase price as described in the immediately preceding sentence,
Norwest may, but shall not be obligated to, waive the condition to closing
contained in this paragraph 7(m), and in such event, BMS shall be obligated to
close  assuming that all other conditions to closing have been satisfied or
waived (but shall not be obligated to reduce the purchase price by the amount
that the Net Cost exceeds $100,000).  Norwest shall have received written
reports containing the conclusions of Phase I and Phase II environmental
assessments and studies pursuant to paragraph 5(u).

  (n)  No change shall have occurred and no circumstances shall exist which
might reasonably be expected to have a material adverse effect on the financial

Subsidiaries taken as a whole (other than changes in banking laws or
regulations, changes in generally accepted accounting principles or
interpretations thereof that affect the banking industry generally or changes in
general economic conditions 

                                      A-45

that uniformly affect the banking industry on a nationwide basis, including
changes in the general level of interest rates).

at the Effective Time of the Merger, BMS shall own, directly or indirectly, and

outstanding capital stock of the BMS Subsidiaries free and clear of any lien,
claim, charge, option, encumbrance or agreement with respect thereto.

  (s) The operations and data processing functions of BMS and the BMS
Subsidiaries, including without limitation those located at the Helena, Montana

     otherwise acquired multiplied by (B) the Adjusted Norwest Shares after all
     adjustments described in subparagraphs 1(i) and 1(iii) through 1(v) are

          (iv) if Norwest reasonably determines that (A) any Losses (as defined

     above divided by (z) the Norwest Measurement Price (as defined below);

          (v) with respect to the environmental investigation and remediation
     and the development and implementation of remediation plans of certain BMS
     properties (other than the costs of any Phase I or II environmental
     assessments),  the Adjusted Norwest Shares shall be reduced by a number
     equal to (A) the lesser of the Net Cost and $100,000 divided by (B) the
     Norwest Measurement Price (as defined below); and

          (vi) the Adjusted Norwest Shares shall be adjusted as provided in
     paragraph (2) below.

                                      A-54
<PAGE>


     The "Norwest Measurement Price" shall mean 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 twenty (20) trading days
ending at the end of the third trading day immediately preceding the Closing
Date (as appropriately and proportionately adjusted in the event that, between
the date hereof and the termination of such twenty trading day period, 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 stock dividend).

     "Losses" shall mean those amounts that the general ledger balancing and
account reconciliation process identifies as 1) reconciling items that do not
represent valid timing differences and with respect to which, as of the date of
determination described in paragraph 1(iv), 45 days has elapsed since the date
of origination of the related individual general ledger account entries, or 2)
out of balance conditions including situations in which the entries in the
general ledger and the subsidiary ledgers do not correspond or situations in
which entries or balances in the general ledger or the subsidiary ledgers are
not supported by valid original source documents or by certifiable systems
applications balances.

     2. If between the date hereof and the time of the 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 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 BMS Common Stock shall be converted pursuant to
     paragraph 1, above, will be appropriately and proportionately adjusted so
     that the number of such shares of Norwest Common Stock into which a share
     of BMS Common Stock shall be converted will equal the number of shares of
     Norwest Common Stock which holders of shares of BMS Common Stock would have
     received pursuant to such reclassification, recapitalization, split-up,
     combination, exchange of shares or readjustment, or stock dividend had the
     record date therefor been immediately following the time of the merger.

     3.  As soon as practicable after the merger becomes effective, each holder
     of a certificate for shares of BMS 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 paragraphs 1 and 2 above.  Until so
     surrendered each certificate which,

                                      A-55
<PAGE>


     immediately prior to the time of merger, represented shares of BMS Common
     Stock shall not be transferable on the books of the surviving corporation
     but shall be deemed to evidence the right to receive cash (with respect to
     shares as to which statutory dissenters' rights have been exercised) or
     (except for the payment of dividends as provided below) ownership of
     (including, but not limited to, the right to vote) the number of whole
     shares of Norwest Common Stock into which such shares of BMS Common Stock
     have been converted on the basis above set forth; provided, however, until
     the holder of such certificate for BMS 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. 
     On any matters relating to such certificates, Norwest may rely conclusively
     upon the record of shareholders maintained by BMS containing the names and
     addresses of the holders of record of BMS Common Stock on the effective
     date of the 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 of a fractional interest shall be paid
     an amount of cash equal to the product obtained by multiplying the
     fractional share interest to which such holder is entitled by the average
     of the closing prices of a share of Norwest Common Stock as reported by the
     consolidated tape of the New York Stock Exchange for each of the five (5)
     trading days immediately preceding the time of merger.

     5.  All shares of Norwest Common Stock and cash for any fractional shares
     issued and paid upon the surrender for exchange of BMS Common Stock in
     accordance with the above terms and conditions shall be deemed to have been
     issued in full satisfaction of all rights pertaining to such shares of BMS
     Common Stock.

     6.  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:

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 BANK OF
MONTANA SYSTEM, a Montana corporation ("BMS").

     Pursuant to an Agreement and Plan of Reorganization, dated as of July __,
1993, (the "Reorganization Agreement"), between BMS and Norwest Corporation, a
Delaware corporation ("Norwest") it is contemplated that a wholly-owned
subsidiary of Norwest will merge with and into BMS (the "Merger") and as a
result, I will receive in exchange for each share of Capital Stock, par value
$2.50 per share, of BMS ("BMS 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 held by me during the 30 days prior to the
Effective Time of the Merger.

     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.

                                      A-60
<PAGE>

     I will not sell, transfer or otherwise dispose of the Stock or in any way
reduce my risk relative to any shares of the Stock issued to me pursuant to the
Merger until such time as financial results covering at least 30 days of post-
Merger combined operations of BMS and Norwest have been published.

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

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

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

     It is understood and agreed that this letter agreement shall terminate and
be of no further force and effect and the restrictive legend set forth above
shall be removed by delivery of substitute certificates without such legend, and
the related stop transfer restrictions shall be lifted forthwith, if (a) (i) any
such shares of Stock shall have been registered under the Securities Act for
sale, transfer or other disposition by me or on my behalf and are sold,
transferred or otherwise disposed of, or (ii) any such shares of Stock are sold
in accordance with the provisions of paragraphs (c), (e), (f) and (g) of Rule
144 promulgated under the Securities Act, or (iii) I am not at the time an
affiliate of Norwest and have been the beneficial owner of the Stock for at
least two years (or such other period as may be prescribed thereunder) and
Norwest has filed with the Commission all of the reports it is required to file
under the Securities Exchange Act of 1934, as amended, during the preceding
twelve months, or (iv) I am not and have not been for at least three months an
affiliate of Norwest and have been the beneficial owner of the Stock for at
least three years (or such other period as may be prescribed by the Securities
Act, and the rules and regulations promulgated thereunder), or (v) Norwest shall
have received an opinion of counsel acceptable to Norwest to the effect that the
stock transfer restrictions and the legend are not required, and (b) financial
results covering at least 30 days of post-Merger combined operations have been
published.

     I have carefully read this letter agreement and the Reorganization
Agreement and have discussed their requirements and other applicable limitations
upon my ability

                                      A-61
<PAGE>

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 BMS.

                                    Sincerely,



                                    _________________________

                        MONTANA BUSINESS CORPORATION ACT

     As used in 35-1-826 through 35-1-839, the following definitions apply:

     (1)  "Beneficial shareholder" means the person who is a beneficial owner of
shares held in a voting trust or by a nominee as the record shareholder.

     (2)  "Corporation" includes the issuer of the shares held by a dissenter
before the corporate action, or the surviving or acquiring corporation by merger
or share exchange of that issuer.

     (3)  "Dissenter" means a shareholder who is entitled to dissent from
corporate action under 35-1-827 and who exercises that right when and in the
manner required by 35-1-829 through 35-1-837.

     (4)  "Fair value", with respect to a dissenter's shares, means the value of
the shares immediately before the effectuation of the corporate action to which
the dissenter objects, excluding any appreciation or depreciation in
anticipation of the corporate action unless exclusion would be inequitable.

     (5)  "Interest" means interest from the effective date of the corporate
action until the date of payment at the average rate currently paid by the
corporation on its principal bank loans or, if the corporation has no loans, at
a rate that is fair and equitable under all the circumstances.

     (6)  "Record shareholder" means the person in whose name shares are
registered in the records of a corporation or the beneficial shareholder to the
extent of the rights granted by a nominee certificate on file with a
corporation.

     (7)  "Shareholder" means the record shareholder or the beneficial
shareholder.

35-1-827.  RIGHT TO DISSENT.

          (1)  A shareholder is entitled to dissent from
and obtain payment of the fair value of the shareholder's shares in the event of
any of the following corporate actions:
     (a) consummation of a plan of merger to which the corporation is a party
     if:
         (i)  shareholder approval is required for the merger by 35-1-815 or
              the articles of incorporation and the shareholder is entitled to
              vote on the merger; or
         (ii) the corporation is a subsidiary that is merged with its parent
              corporation under 35-1-818;

                                      B-1
<PAGE>

     (b)  consummation of a plan of share exchange to which the corporation is a
          party as the corporation whose shares will be acquired if the
          shareholder is entitled to vote on the plan;
     (c)  consummation of a sale or exchange of all or substantially all of the
          property of the corporation other than in the usual and regular course
          of business if the shareholder is entitled to vote on the sale or
          exchange, including a sale in dissolution but not including a sale
          pursuant to court order or a sale for cash pursuant to a plan by which
          all or substantially all of the net proceeds of the sale will be
          distributed to the shareholders within 1 year after the date of sale;
     (d)  an amendment of the articles of incorporation that materially and
          adversely affects rights in respect of a dissenter's shares because
          it:
          (i)   alters or abolishes a preferential right of the shares;
          (ii)  creates, alters, or abolishes a right in respect of redemption,
                including a provision with respect to a sinking fund for the
                redemption or repurchase of the shares;
          (iii) alters or abolishes a preemptive right of the holder of the
                shares to acquire shares or other securities;
          (iv)  excludes or limits the right of the shares to be voted on any
                matter or to cumulate votes, other than a limitation by dilution
                through issuance of shares or other securities with similar
                voting rights; or
          (v)   reduces the number of shares owned by the shareholder to a
                fraction of a share if the fractional share created is to be
                acquired for cash under 35-1-621; or
     (e)  any corporate action taken pursuant to a shareholder vote to the
          extent the articles of incorporation, bylaws, or a resolution of the
          board of directors provides that voting or nonvoting shareholders are
          entitled to dissent and to obtain payment for their shares.

     (2)  A shareholder entitled to dissent and to obtain payment for shares
under 35-1-826 through 35-1-839 may not challenge the corporate action creating
the shareholder's entitlement unless the action is unlawful or fraudulent with
respect to the shareholder or the corporation.

35-1-828.  DISSENT BY NOMINEES AND BENEFICIAL OWNERS.

     (1)  A record shareholder may assert dissenters' rights as to fewer than
all the shares registered in his name only if he dissents with respect to all
shares beneficially owned by any one person and notifies the corporation in
writing of the name and address of each person on whose behalf he asserts
dissenters' rights.  The rights of a partial dissenter under this subsection are
determined as if the shares as to which he dissents and his other shares were
registered in the names of different shareholders.

     (2)  A beneficial shareholder may assert dissenters' rights as to shares
held on his behalf only if:

                                      B-2
<PAGE>

     (a)  he submits to the corporation the record shareholder's written consent
          to the dissent not later than the time the beneficial shareholder
          asserts dissenters' rights; and
     (b)  he does so with respect to all shares of which he is the beneficial
          shareholder or over which he has power to direct the vote.

under 35-1-826 through 35-1-839 and must be accompanied by a copy of 35-1-826
through 35-1-839.

     (2)  If a corporate action creating dissenters' rights under 35-1-827 is
taken without a vote of shareholders, the corporation shall give written

          certificates for certified shares must be deposited;
     (b)  inform shareholders of uncertificated shares to what extent transfer
          of the shares will be restricted after the payment is received;
     (c)  supply a form for demanding payment that includes the date of the
          first announcement to news media or to shareholders of the terms of
          the proposed corporate action and that requires the person asserting
          dissenters' rights to certify whether or not he acquired beneficial
          ownership of the shares before that date;

                                      B-3

<PAGE>

     (d)  set a date by which the corporation must receive the payment demand,
          which may not be fewer than 30 nor more than 60 days after the date

terms of the notice.

     (2)  The shareholder who demands payment and deposits his certificates
under subsection (1) retains all other rights of a shareholder until these
rights are canceled or modified by the taking of the proposed corporate action.

     (3)  A shareholder who does not demand payment or deposit his certificates
where required, each by the date set in the dissenters' notice, is not entitled

35-1-833.  SHARE RESTRICTIONS.

     (1)  The corporation may restrict the transfer of uncertificated shares
from the date the demand for their payment is received until the proposed
corporate action is taken or the restrictions are released under 35-1-835.

     (2)  The person for whom dissenters' rights are asserted as to
uncertificated shares retains all other rights of a shareholder until these
rights are canceled or modified by the taking of the proposed corporate action.

35-1-834.  PAYMENT.

     (1)  Except as provided in 35-1-836, as soon as the proposed corporate
action is taken or upon receipt of a payment demand, the corporation shall pay

to be the fair value of the dissenter's shares plus accrued interest.

     (2)  The payment must be accompanied by:
     (a)  the corporation's balance sheet as of the end of a fiscal year ending
          not more than 16 months before the date of payment, an income
          statement for that year, a statement of changes in shareholders'
          equity for that year, and the latest available interim financial
          statements, if any;

                                      B-4

<PAGE>

     (b)  a statement of the corporation's estimate of the fair value of the
          shares;
     (c)  an explanation of how the interest was calculated;
     (d)  a statement of the dissenter's right to demand payment under 35-1-837;
          and
     (e)  a copy of 35-1-826 through 35-1-839.

35-1-835.  FAILURE TO TAKE ACTION.

     (1)  If the corporation does not take the proposed action within 60 days
after the date set for demanding payment and depositing certificates, the
corporation shall return the deposited certificates and release the transfer
restrictions imposed on uncertificated shares.

     (2)  If after returning deposited certificates and releasing transfer
restrictions, the corporation takes the proposed action, it shall send a new
dissenters' notice under 35-1-831 and repeat the payment demand procedure.

35-1-836.  AFTER-ACQUIRED SHARES.

     (1)  A corporation may elect to withhold payment required by 35-1-834 from
a dissenter unless the dissenter was the beneficial owner of the shares before
the date set forth in the dissenters' notice as the date of the first
announcement to news media or to shareholders of the terms of the proposed
corporate action.

     (2)  To the extent the corporation elects to withhold payment under
subsection (1), after taking the proposed corporate action, the corporation
shall estimate the fair value of the shares plus accrued interest and shall pay
this amount to each dissenter who agrees to accept it in full satisfaction of
his demand.  The corporation shall send with its offer a statement of its
estimate of the fair value of the shares, an explanation of how the interest was
calculated, and a statement of the dissenter's right to demand payment under 35-
1-837.

35-1-837.  PROCEDURE IF SHAREHOLDER DISSATISFIED WITH PAYMENT OR OFFER.

     (1)  A dissenter may notify the corporation in writing of the dissenter's
own estimate of the fair value of the dissenter's shares and the amount of
interest due and may demand payment of the dissenter's estimate, less any
payment under 35-1-834, or reject the corporation's offer under 35-1-836 and
demand payment of the fair value of the dissenter's shares and the interest due
if:
     (a)  the dissenter believes that the amount paid under 35-1-834 or offered
          under 35-1-836 is less than the fair value of the dissenter's shares
          or that the interest due is incorrectly calculated;
     (b)  the corporation fails to make payment under 35-1-834 within 60 days
          after the date set for demanding payment; or
     (c)  the corporation, having failed to take the proposed action, does not
          return the deposited certificates or release the transfer restrictions
          imposed on 

                                      B-5

<PAGE>

          uncertificated shares within 60 days after the date set for
          demanding payment.

     (2)  A dissenter waives the right to demand payment under this section
unless he notifies the corporation of his demand in writing under subsection (1)
within 30 days after the corporation made or offered payment for his shares.

35-1-838.  COURT ACTION.

     (1)  If a demand for payment under 35-1-837 remains unsettled, the
corporation shall commence a proceeding within 60 days after receiving the
payment demand and shall petition the court to determine the fair value of the
shares and accrued interest.  If the corporation does not commence the
proceeding within the 60-day period, it shall pay each dissenter whose demand
remains unsettled the amount demanded.

     (2)  The corporation shall commence the proceeding in the district court of
the county where a corporation's principal office or, if its principal office is
not located in this state, where its registered office is located.  If the
corporation is a foreign corporation without a registered office in this state,
it shall commence the proceeding in the county in this state where the
registered office of the domestic corporation merged with or whose shares were
acquired by the foreign corporation was located.

     (3)  The corporation shall make all dissenters whose demands remain
unsettled, whether or not residents of this state, parties to the proceeding as
in an action against their shares, and all parties must be served with a copy of
the petition.  Nonresidents may be served by certified mail or by publication as
provided by law.

     (4)  The jurisdiction of the district court in which the proceeding is
commenced under subsection (2) is plenary and exclusive.  The court may appoint
one or more persons as appraisers to receive evidence and recommend decision on
the question of fair value.  The appraisers have the powers described in the
order appointing them or in any amendment to it.  The dissenters are entitled to
the same discovery rights as parties in other civil proceedings.

     (5)  Each dissenter made a party to the proceeding is entitled to judgment:
     (a)  for the amount, if any, by which the court finds the fair value of the
          dissenter's shares plus interest exceeds the amount paid by the
          corporation; or
     (b)  for the fair value plus accrued interest of his after-acquired shares
          for which the corporation elected to withhold payment under 35-1-836.

35-1-839.  COURT COSTS AND ATTORNEY FEES.

     (1)  The court in an appraisal proceeding commenced under 35-1-838 shall
determine all costs of the proceeding, including the reasonable compensation and
expenses 

                                      B-6

<PAGE>

of appraisers appointed by the court.  The court shall assess the costs
against the corporation, except that the court may assess costs against all or
some of the dissenters, in amounts the court finds equitable, to the extent the
court finds dissenters acted arbitrarily, vexatiously, or not in good faith in
demanding payment under 35-1-837.

     (2)  The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable:
     (a)  against the corporation and in favor of any or all dissenters if the
          court finds the corporation did not substantially comply with the
          requirements of 35-1-829 through 35-1-837; or
     (b)  against either the corporation or a dissenter, in favor of any other
          party, if the court finds that the party against whom the fees and
          expenses are assessed acted arbitrarily, vexatiously, or not in good
          faith with respect to the rights provided by 35-1-826 through 35-1-
          839.

     (3)  If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated and that the fees
for those services should not be assessed against the corporation, the court may
award the counsel reasonable attorney fees to be paid out of the amounts awarded
the dissenters who were benefited.

                         OPINION OF D.A. DAVIDSON & CO.



<PAGE>

                     Form of Opinion of D.A. Davidson & Co.



  February ___, 1994



  Board of Directors
  Bank of Montana System
  c/o Central Financial Services
  The Colonnade
  5500 Wayzata Boulevard
  Golden Valley, MN  55416

  Gentlemen and Ms. Forster:

  In connection with the proposed merger transaction ("Merger") whereby a
  wholly-owned subsidiary of Norwest Corporation ("Purchaser") will merge with
  and into Bank of Montana System ("BMS"), you have requested our opinion as to
  the fairness, from a financial point of view, to the holders of shares of BMS
  common stock ("BMS Shareholders") of the 4,200,000 shares of common stock of
  Norwest Corporation (the "Consideration") to be received by BMS Shareholders
  as a result of the Merger.

  D.A. Davidson & Co. is engaged in the valuation of businesses and their
  securities in the course of its business as an investment firm.  For our
  services in connection with the Merger, D.A. Davidson & Co. was paid a fee
  upon delivery of this opinion, and BMS will indemnify D.A. Davidson & Co.
  against certain liabilities.

  In arriving at our opinion, we have undertaken such reviews, analyses and
  inquiries as we deemed necessary and appropriate under the circumstances.
  Among other things, we have reviewed a draft of the Agreement setting forth
  the proposed terms of the Merger; audited financial statements of BMS for the
  years ended December 31, 1988-1992; consolidated reports of condition and
  income ("call reports") for BMS, Bank of Montana Butte and Montana Bank of
  Billings as of March 31, 1993; the Application to the Board of Governors of
  the Federal Reserve System (as amended) by BMS to acquire Montana Bancsystem,
  Inc. ("MBI") including certain financial projections contained therein;
  unaudited financial statements of BMS and MBI at and for the six months ended
  June 30, 1993; budgeted financial results for BMS and MBI for the year ending
  December 31, 1993; various internally-prepared financial reports and schedules
  regarding BMS and MBI; securities data of publicly traded financial
  institutions; financial terms, to the extent publicly available, of certain
  merger and acquisition transactions; and, certain financial and common stock
  performance information with respect to Norwest Corporation.  Additionally, we
  have held discussions with members of BMS management concerning the financial
  condition, operating results and business prospects for BMS.

                                      C-1

  Board of Directors
  February ___, 1994


  We have relied upon and assumed the accuracy, completeness and fairness of the
  financial statements and other information provided by BMS or otherwise made
  available to us and we have not attempted independently to verify such
  information.  We have further relied upon the assurances of BMS management
  that they are not aware of any information or facts that would make the
  information provided to us incomplete or misleading.  In arriving at our
  opinion, we have not performed any appraisal or valuation of specific assets
  or liabilities of BMS.  We have not been authorized to solicit, and did not
  solicit, any indications of interest with respect to the purchase of BMS by
  other parties.  Our opinion necessarily is based upon market, economic,
  financial and other conditions as they exist and can be evaluated on the date
  hereof.

  Based upon and subject to the foregoing and based upon such other factors as
  we consider relevant, it is our opinion that the Consideration to be received
  by BMS Shareholders in connection with the Merger is fair, from a financial
  point of view, to such BMS Shareholders as of the date hereof.

  Very truly yours,

  D.A. DAVIDSON & CO.

  Vice President

  Item 22.  Undertakings
            ------------

    (a)  The undersigned registrant hereby undertakes:

       (1) To file, during any period in which offers or sales are being made, a
           post-effective amendment to this registration statement:  (i) to
           include any prospectus required by section 10(a)(3) of the Securities
           Act of 1933; (ii) to reflect in the prospectus any facts or events
           arising after the effective date of the registration statement (or
           the most recent post-effective amendment thereof) which, individually
           or in the aggregate, represent a fundamental change in the
           information set forth in the registration statement; and (iii) to
           include any material information with respect to the plan of
           distribution not previously disclosed in the registration statement
           or any material change to such information in the registration
           statement.

                                      II-2
<PAGE>

       (2) That, for the purpose 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.

       (3) To remove from registration by means of a post-effective amendment
           any of the securities being registered which remain unsold at the
           termination of the offering.

    (b)   The undersigned registrant hereby undertakes that, for purposes of
  determining any liability under the Securities Act of 1933, each filing of the
  registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
  Securities Exchange Act of 1934 (and, where applicable, each filing of an
  employee benefit plan's annual report pursuant to Section 15(d) of the
  Securities Exchange Act of 1934) that is incorporated by reference in the
  registration statement shall be deemed to be a new registration statement
  relating to the securities offered therein, and the offering of such
  securities at that time shall be deemed to be the initial bona fide offering
  thereof.

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

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

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

                                      II-3
<PAGE>

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

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

  Ladies and Gentlemen:

       In connection with the proposed registration under the Securities Act of
  1933, as amended, of 4,200,000 shares of common stock (the "Shares"), par
  value $1 2/3 per share, and 4,200,000 rights to purchase Series A Junior
  Participating Preferred Stock (the "Rights") without par value, of the
  Corporation, which are proposed to be issued by the Corporation in connection
  with the proposed merger of a wholly owned subsidiary of the Corporation into
  Bank of Montana System, a Montana 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 the Rights 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 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 and the Rights to be issued
  by the Corporation in connection with the Merger, and when issued pursuant to
  the Merger as contemplated by 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

       RE:  Federal Income Tax Consequences of Merger of _________________
            with and into Bank of Montana System

  Ladies and Gentlemen:

       We have acted as counsel to Bank of Montana System, a Montana corporation
  ("BMS"), in connection with the merger of __________________, a Montana
  corporation ("Merger Co."), a wholly-owned subsidiary of Norwest Corporation,
  a Delaware corporation ("Norwest"), with and into BMS pursuant to that certain
  Agreement and Plan of Reorganization dated as of September 13, 1993, by and
  between BMS and Norwest (the "Merger Agreement").  Unless otherwise provided
  herein, capitalized terms used herein shall have the meanings assigned to them
  in the Registration Statement on Form S-4 which has been delivered to the
  Securities and Exchange Commission in connection with the Merger (the
  "Registration Statement").

       At the Effective Time of the Merger and pursuant to the Merger Agreement,
  Merger Co. will be merged with and into BMS and the separate existence of
  Merger Co. will cease.  Pursuant to the Merger, each share of BMS Common Stock
  issued and outstanding at 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 Norwest Common
  Stock determined by dividing the Adjusted Norwest Shares by the number of
  shares of BMS Common Stock then issued and outstanding.  Norwest will issue
  cash in lieu of fractional shares of Norwest Common Stock pursuant to the
  Merger.

       BMS has asked for our opinion concerning certain federal income tax
  consequences of the Merger.  For purposes of rendering this opinion, we have
  examined the Merger Agreement, the Registration Statement, and such other
  instruments and documents as we have deemed necessary or appropriate, and we
  have reviewed such questions of law as we have considered necessary or
  appropriate.

       Our opinion is based upon the existing provisions of the Internal Revenue
  Code of 1986, as amended (the "Code"), the current Treasury Department
  Regulations issued

<PAGE>



  Bank of Montana System
  _____________, 1994
  Page 2


  thereunder, the current published administrative positions of the Internal
  Revenue Service contained in revenue rulings, revenue procedures and other
  administrative pronouncements, and judicial decisions, all of which are
  subject to change prospectively and retroactively.  Any change in such
  authorities may affect the opinions rendered herein.  In rendering this
  opinion, we have relied upon the representations and warranties set forth in
  the Merger Agreement and the representations set forth in the Certificates of
  even date herewith delivered to us by BMS, Norwest and certain shareholders of
  BMS (the "Certificates").  Our opinion is also based on the assumption that
  BMS and Norwest will at all times comply with the terms of the Merger
  Agreement and that the Merger will be consummated in the manner described
  therein.

       An opinion of counsel is predicated upon all the facts and conditions set
  forth in the opinion and is based upon counsel's analysis of the statutes,
  regulatory interpretations and case law in effect as of the date of the
  opinion.  It is not a guarantee of the current status of the law and should
  not be accepted as a guarantee that a court of law or an administrative agency
  will concur in the opinion.

       Based upon the foregoing, it is our opinion that the following federal
  income tax consequences will result from the Merger:

       1.   The Merger will qualify as a reorganization under Sections
  368(a)(1)(A) and 368(a)(2)(E) of the Code.

       2.   Under Section 354(a)(1) of the Code, no gain or loss will be
  recognized by the shareholders of BMS upon the exchange of BMS Common Stock
  solely for Norwest Common Stock pursuant to the Merger (but see item 5 below
  with respect to cash payments in lieu of fractional shares).

       3.   Under Section 358(a)(1) of the Code, the basis of the Norwest Common
  Stock received by the shareholders of BMS pursuant to the Merger, including
  any fractional shares deemed received as described in item 5 below, will be
  the same as the basis of the BMS Common Stock surrendered in exchange
  therefor.

       4.   Under Section 1223(1) of the Code, the holding period of the Norwest
  Common Stock received by the shareholders of BMS pursuant to the Merger will
  include the period during which the BMS Common Stock surrendered therefor was
  held, provided that such BMS Common Stock was a capital asset in the hands of
  the shareholders of BMS at the Effective Time of the Merger.

       5.   Under Rev. Rul. 66-365, 1966-2 C.B. 116, and Rev. Proc. 77-41, 1977-
  2 C.B. 574, the payment of cash to shareholders of BMS in lieu of fractional
  share interests of Norwest Common Stock will be treated as if the fractional
  shares were distributed as part of the Merger and then were redeemed by
  Norwest.  These cash payments will be treated as having been received as
  distributions in full payment in exchange for the Norwest Common Stock
  redeemed as provided in Section 302(a) of the Code.

       The foregoing opinion is being furnished to you solely for your benefit
  in connection with the Merger and may not be relied upon by, nor may copies be
  delivered to, any person without our prior written consent.  Our opinion is
  limited to the matters expressly addressed in the five (5) numbered paragraphs
  above.  No opinion is expressed and none should be inferred as to any other
  matter.

       Our opinion is effective as of the date hereof and will remain effective
  as of the Effective Time of the Merger provided that (i) the representations
  and warranties set forth in the Merger Agreement remain true and correct as of
  the Effective Time of the Merger, (ii) the representations set forth in the
  Certificates remain true and correct as of the Effective Time of the Merger,
  (iii) the Merger is consummated in accordance with the present terms of the
  Merger Agreement, and (iv) there are no relevant changes in the Code, the
  Treasury Department Regulations issued thereunder, or administrative or
  judicial interpretations thereof.
