                                  PROSPECTUS SUMMARY

The following summary is qualified in its entirety by and should be read in
conjunction with the more detailed information and the consolidated financial
statements and notes thereto appearing elsewhere in this Prospectus.  The term
"Company" when used in this Prospectus includes, when the context so requires,
First Interstate BancSystem of Montana, Inc., its predecessors, and its
subsidiaries.  Prospective investors should carefully consider the information
set forth under the heading "Risk Factors".

THE COMPANY

The principal executive office of the Company is located at 401 North 31st 
Street, Billings, Montana 59101, and its telephone number is (406) 255-5300. 
   
First Interstate BancSystem of Montana, Inc.  is a bank holding company under 
the Bank Holding Company Act of 1956 ("Act") and is a savings and loan 
holding company under the Home Owners' Loan Act.  FIBM was incorporated on 
March 15, 1971.  FIBM's primary business is that of managing its wholly owned 
subsidiaries, First Interstate Bank in Montana ("FIB Montana"), First 
Interstate Bank in Wyoming ("FIB Wyoming"), First Interstate Bank, fsb in 
Hamilton, Montana ("First Interstate, fsb"), and Commerce Financial, Inc. 
("CFI").  FIB Montana has eighteen banking offices in thirteen Montana 
communities.  FIB Wyoming has nine banking offices in seven Wyoming 
communities. First Interstate, fsb was opened as a de novo savings bank on 
December 12, 1996 and currently has only one banking office.
    
In addition to management of its subsidiaries, FIBM has a data processing
division headquartered in Billings, Montana, which performs data processing
services for FIBM's subsidiaries, and 35 non-affiliated financial institutions
with 79 locations in Montana, Wyoming and Idaho.  The data processing division
also provides ATM support for 138 financial institutions in Montana, Wyoming,
Idaho, Colorado and North Dakota.

In addition to being the sole shareholder, FIBM functions as a service
organization for each of its subsidiaries.  FIBM provides advice, counsel and
specialized services to its subsidiaries in connection with a wide range of
banking and operating policies and activities.  These services include data
processing, auditing, credit administration, planning coordination, marketing,
human resources management, asset/liability management and investments.

FIBM generates its income from (1) dividends received from Subsidiaries, (2)
undistributed earnings of Subsidiaries, (3) management fees charged to
Subsidiaries,  (4) net data processing income, and (5) other income, principally
federal income tax benefits.

BUSINESS OF FIBM'S SUBSIDIARIES
   
FIB Montana is a Montana chartered bank originally incorporated in 1916, 
having its principal office in Billings, Montana.  FIB Montana currently has 
eighteen banking offices in thirteen Montana communities - Billings, Bozeman, 
Missoula, Hardin, Miles City, Colstrip, Livingston, Gardiner, Great Falls, 
Kalespell, Whitefish, Cut Bank, and Evergreen.  The present structure of FIB 
Montana began December 1, 1992, when FIBM merged its eight Montana subsidiary 
banks, which became a state/federal reserve member bank with eight offices. 
FIB Montana opened an additional banking office in Billings, Montana in 
December 1994, and an additional banking office in Missoula, Montana in 
January 1995.  Acquisitions in 1995 and 1996 increased FIB Montana's banking 
offices to the current number of eighteen.

FIB Wyoming is a Wyoming chartered bank originally incorporated in 1893 
and currently has nine banking offices in seven Wyoming communities 
- -Sheridan, Gillette, Greybull, Buffalo, Casper, Laramie, and Riverton. The 
present structure of FIB Wyoming was created on December 30, 1988, when FIBM 
merged its five Wyoming subsidiary banks, which became a state non-federal 
reserve member bank with six offices. Acquisitions in 1996 increased FIB 
Wyoming's banking offices to nine. 
    

   
    

First Interstate, fsb is a nationally chartered savings bank with its only
office located in Hamilton, Montana.  First Interstate, fsb was a de novo
charter, and first opened for business on December 12, 1996.

   
    

FIBM's banking subsidiaries are each engaged in general commercial banking
activities, including all types of demand and time deposits, trust services, and
commercial, agricultural, real estate, personal and consumer loans.  The banks
also provide such other services as are generally furnished by commercial banks
located in the principal cities and towns of Montana and Wyoming.

CFI, FIBM's only nonbank subsidiary, was incorporated in 1978, principally to
originate and broker secured real estate loans.  During the past five years,
CFI's principal activity has been the liquidation of assets acquired through
foreclosure actions by FIBM.

REGULATION AND  SUPERVISION

regulated under both federal and state law.  Any change in applicable law or
regulation may have a material effect on the business and prospects of the

RESTRICTIONS ON RESALE
   
Purchasers of the FIBM stock offered hereby, except for purchasers acquiring 
stock through the Savings Plan, will be subject to a Shareholder's Agreement 
which will limit transferability of the stock, and will allow FIBM the option 
to repurchase the stock upon the shareholder's death or disability, or upon 
termination of the shareholder's status as an officer, director, or employee of 
FIBM, or upon any intended sale or transfer of the stock.  Stock subject to 
the Shareholder's Agreement may not be sold or transferred by the shareholder 
without triggering FIBM's option to acquire the stock in accordance with the 
terms of the Shareholder's Agreement.  In addition, the Shareholder's 
Agreement allows FIBM to repurchase any of the FIBM Stock acquired by the 
shareholder after January 1, 1994 if FIBM determines that the number of 
shares owned by the shareholder is excessive in view of a number of factors 
including but not limited to (a) the relative contribution of the shareholder 
to the economic performance of the Company, (b) the effort being put forth by 
the shareholder, and (c) the level of responsibility of the shareholder.  
This restriction is intended to allow FIBM to reduce or eliminate a 
shareholder's stock ownership is FIBM in circumstances where the 
shareholder's employment role, responsibility or contribution to the success 
of the Company has been reduced or has declined.  To date, FIBM has not 
exercised its rights under this restriction.  The Shareholders Agreement 
applies to all shareholders of FIBM except Scott Family members and 13 
shareholders (including the Savings Plan) owning 123,674 shares of 
unrestricted FIBM stock. The repurchase price is the appraised value per 
share determined using the most recent quarterly appraisal availiable to FIBM 
less dividends paid since the end of the quarter for which the value of the 
stock has been determined in that appraisal.  See "RISK FACTORS - 
RESTRICTIONS ON RESALE OF FIBM STOCK" and "DESCRIPTION OF CAPITAL STOCK - 
RESTRICTIONS ON RESALE".
    
The Shareholder's Agreement limits the marketability of FIBM Stock, and may 
preclude the development of any trading market for FIBM Stock.  Shareholders 
may be unable to sell their stock as and when desired, and for the highest 
price available.

INTEREST OF CERTAIN PERSONS
   
The directors and executive officers of FIBM (11 persons) beneficially owned 
as of July 31, 1997, 1,269,355 shares directly or indirectly, or 63.79% 
percent, of FIBM Stock, excluding any options outstanding but unexercised.  
The remaining shares of FIBM Stock are owned by 401 shareholders.  See 
"PRINCIPAL HOLDERS OF VOTING SECURITIES".  Members of the Scott Family own 
83.21% percent of the FIBM Stock as of July 31, 1997.

RISK FACTORS

See "RISK FACTORS" for a discussion of certain factors which should be
considered by offerees in connection with this offering.

<PAGE>

                                  RISK FACTORS

An investment in the common stock offered hereby involves a high degree of risk.
In addition to the other information contained in this Prospectus, the following
risk factors should be carefully considered before purchasing shares of common
stock offered hereby.

STOCK NOT INSURED

The shares of FIBM common stock offered hereby are not savings accounts or 
deposits and are not insured by the Federal Deposit Insurance Corporation or 
any other government agency.

ABSENCE OF MARKET FOR FIBM STOCK

No public trading market exists for FIBM Stock, and none is anticipated to 
exist in the future.  See "COMMON STOCK MARKET AND VALUATION INFORMATION".  
Investors should have a long term investment intent.  There have been no 
sales of FIBM Stock in the past three years other than sales of stock by the 
Scott Family and redemptions of stock by FIBM under the Shareholder's Agreement.

FIBM has no obligation, by contract, policy or otherwise, to purchase stock 
from any shareholder desiring to sell, or to create any market for the 
stock.  Historically, it has been the practice of FIBM to repurchase common 
stock to maintain a shareholder base with restrictions on sale or transfer of 
the stock.  See "RESTRICTION ON RESALE OF FIBM STOCK".  In the last three 
calendar years (1994-1996) FIBM has redeemed a total of 52,066 shares of 
common stock, all of which was restricted by the Shareholder's Agreement.  
FIBM has no present intention to change its historical practice for redemption 
of stock, but no assurances can be provided that FIBM will not change or end 
its practice of redeeming stock.  Furthermore, FIBM redemptions of stock 
are subject to corporate law and regulatory restrictions which could prevent 
stock redemptions.

RESTRICTIONS ON RESALE OF FIBM STOCK

Resale of FIBM Stock may be restricted pursuant to the Securities Act of 1933
and applicable state securities laws.  In addition, most shares of FIBM Stock
are subject to one of two shareholder's agreements.  Members of the Scott
Family, as majority shareholders of FIBM, are subject to a Shareholder's
Agreement (referred to herein as the "Scott Agreement").  The Scott Family,
under the Scott Agreement, has agreed to limit the transfer of shares owned by
members of the Scott Family to family members or charities, or with FIBM's
approval, to the Company's officers, directors, advisory directors, or to the
Company's Savings Plan.
   
Shareholders of FIBM who are not Scott Family members (with the exception of 
13 shareholders (including the Savings Plan) who own 123,674 shares of 
unrestricted stock) are subject to a different Shareholder's Agreement 
(referred to herein as the "Shareholder's Agreement").  SEE EXHIBIT A HERETO. 
Stock subject to the Shareholder's Agreement may not be sold or transferred 
by the shareholder without triggering FIBM's option to acquire the stock in 
accordance with the terms of the Shareholder's Agreement.  The Shareholder's 
Agreement grants FIBM the option to purchase the FIBM Stock restricted 
thereby at the minority appraised value per share based upon the most recent 
quarterly appraisal available to FIBM less dividends paid since the end of 
the quarter for which the value of the stock has been determined in that 
appraisal.  FIBM is required under the Shareholder's Agreement to obtain, at 
its expense, an appraisal of FIBM shares of common stock as of the last day 
of each calendar quarter prepared by an unaffiliated firm qualified to make 
such an appraisal.  The appraiser will take into account the minority, or 
non-controlling, size of the block of stock to be valued, which will result 
in an appraised value which is less than a majority, or controlling, block of 
stock.  FIBM's purchase option arises in any of the following events:  (1) 
the shareholder's intention to sell the stock, (2) the shareholder's death, 
(3) transfer of the stock by operation of law, (4) termination of the 
shareholder's status as a director, officer or employee of FIBM, and (5) 
total disability of the shareholder.  In addition, the Shareholder's 
Agreement allows FIBM to repurchase any of the FIBM Stock acquired by the 
shareholder after January 1, 1994 if FIBM determines that the number of 
shares owned by the shareholder is excessive in view of a number of factors 
including but not limited to (a) the relative contribution of the shareholder 
to the economic performance of the Company, (b) the effort being put forth by 
the shareholder, and (c) the level of responsibility of the shareholder.  
This restriction is intended to allow FIBM to reduce or eliminate a 
shareholder's stock ownership in FIBM in circumstances where the 
shareholder's employment role, responsibility or contribution to the success 
of the Company has been reduced or has declined. To date, FIBM has not 
exercised its rights under this restriction.
    
                                          6

<PAGE>

Any of the FIBM Stock purchased through this offering, except for purchases
through the Savings Plan, will be subject to the terms of the Shareholder's
Agreement, and the purchaser will be required to accept in writing the terms and
conditions of the Shareholder's Agreement.  See "DESCRIPTION OF CAPITAL STOCK -
RESTRICTIONS ON RESALE".  FIBM has not sought an opinion of counsel regarding 
the validity or enforceability of any of the restrictions contained in the 
Shareholder's Agreement. Enforcement of the excess stock ownership restriction 
contained in the Shareholder's Agreement may be an unsettled issue, since no 
Montana legal authority exists with respect to the enforceability of such a 
restriction.  Initial determinations as to any claimed violation of the 
Shareholder's Agreement will be made by FIBM, although any final determination
may be made in court.

Purchases of FIBM Stock made through the Savings Plan will not be restricted by
the Shareholder's Agreement, due to requirements of ERISA and the Internal
Revenue Code.  However, since the Savings Plan does not allow distributions in
kind, any distributions from an employee's account in the Savings Plan will
allow, and may require, the Savings Plan trustee to sell the FIBM stock.  While
FIBM has no obligation to repurchase the stock, it is possible that FIBM will
repurchase FIBM stock sold out of the Savings Plan.  Any such repurchases would
be upon terms set by the Savings Plan trustee and accepted by FIBM.

The restrictions on resale of FIBM common stock will greatly limit the
marketability of the stock, and the appraised value price prescribed under the
Shareholder's Agreement may be less than the purchase price paid by a
shareholder for the stock and may be less than the actual value of the stock.

CONTROL BY SCOTT FAMILY
   
The Scott Family owns 83.21% of the outstanding common stock of FIBM as of July
31, 1997, and will therefore be able to control the election of directors and
the determination of business issues including merger, share exchange, sale of
assets outside the ordinary cause of business, and dissolution.  See
"DESCRIPTION OF CAPITAL STOCK - COMMON STOCK" and "PRINCIPAL HOLDERS OF VOTING
SECURITIES".  A purchaser of the common stock offered hereby will be a minority
shareholder, and will have no control over business decisions of the Company,
including those issues stated above.
    
STOCK PRICE FLUCTUATION

Determination of the minority appraised value of FIBM Stock subject to the
Shareholder's Agreement may fluctuate depending upon factors such as the results
of operations of the Company, changes in the value of assets of the Company,
accuracy of estimates of future cash flows of the Company, the factors
considered and methodology employed by the appraiser, and possible changes in
the appraiser hired by FIBM to complete the appraisal.  No assurance can be
given that the appraised value and price of the stock offered herein will not
fluctuate substantially in the future, or that the appraised value will
accurately reflect the value of the stock.

RESTRICTIONS ON DIVIDENDS

As a bank holding company, FIBM is dependent upon cash flow from its
Subsidiaries, received through dividends or other intercompany transfers of
funds, to service its debt and meet operating expenses and other obligations.
The loan agreement governing FIBM's existing indebtedness with its primary
lenders contains certain limitations on the payment of dividends by subsidiaries
of FIBM, and contains limitations on FIBM's payment of dividends to its
shareholders.  See "DESCRIPTION OF CAPITAL STOCK - DIVIDEND RESTRICTIONS",
"DIVIDEND POLICY", "BUSINESS - GENERAL" and "MANAGEMENT'S DISCUSSION AND
ANALYSIS OF CONSOLIDATED FINANCIAL CONDITION AND RESULTS OF OPERATIONS -
GENERAL".  In addition, FIBM's banking subsidiaries may pay dividends and make
certain other inter-company transfers of funds only as permitted by federal and
state banking laws and regulations.  See "DESCRIPTION OF CAPITAL STOCK -
DIVIDEND RESTRICTIONS" and "BUSINESS - REGULATION AND SUPERVISION".  Dividends
from FIBM's banking subsidiaries are expected to be FIBM's major source of
liquidity.  These limitations on the payment of dividends and transfers of funds
could adversely restrict payment of dividends to stockholders.

<PAGE>

KEY PERSONNEL


The Company believes that its continued success depends to a significant extent
on the management skills of its directors and executive officers, many of whom
have held director and officer positions with the Company for a number of years.
See "MANAGEMENT".  The Company maintains key person life insurance on Homer
Scott, Jr., Dan Scott, Thomas W. Scott, James R. Scott, and Susan Scott Heyneman
in the amount of $1,650,000, $1,650,000, $1,500,000, $1,000,000 and $1,200,000,
respectively, the proceeds of which are payable to the Company, but which may be
required to be used to redeem FIBM stock owned by the decedent if the decedent's
personal representative so elects, pursuant to the terms of the Scott Agreement.
Although the Company has been able to attract and retain experienced and
qualified management personnel, the loss or unavailability of current members of
management could have an adverse effect on the Company.

COMPETITION

The banking business in both Montana and Wyoming is highly competitive with
respect to both loans and deposits.  Many of the Company's competitors are
substantially larger and have more capital and other resources than the Company.
The Company's future performance will be subject to a number of legal and
economic factors beyond its control, such as state and federal banking
legislation, regulatory changes, unforeseen legal outcomes, inflation, material
lending and deposit rates, interest rate changes, and local market economies.
The Riegel-Neal Interstate Banking and Branching Efficiency Act of 1994 is
expected to increase competition, particularly from larger, multi-state banks.
See "BUSINESS - COMPETITION" and "BUSINESS - REGULATION AND SUPERVISION".

POTENTIAL EFFECTS OF CHANGES IN INTEREST RATES

The profitability of FIBM's bank subsidiaries, like that of many financial
institutions, is dependent to a large extent upon their net interest income,
which is the difference between their interest income on interest-earning
assets, such as loans and investments, and their interest expense on interest-
bearing liabilities, such as deposits and borrowings.  When interest-bearing
liabilities mature or reprice more quickly than interest-earning assets in a
given period, a significant increase in market rates of interest could adversely
affect net interest income.  Conversely, a significant decrease in market rates
of interest could result in increased net interest income.  Increases in
interest rates also can result in disintermediation, which is the flow of funds
away from banking organizations into direct investments, such as U.S. Government
and corporate securities, and other investment vehicles which, due in part to
the absence of federal insurance premiums and reserve requirements, generally
can pay higher rates of return than banks.

At December 31, 1996, the Company's interest-bearing liabilities which were
estimated to mature or reprice within one year exceeded interest-earning assets
with the same characteristics by $437 million or 24.5% of the Company's total
interest-earning assets.  This large rate sensitivity gap could subject the
Company to risk during periods of rising interest rates, which would have
negative effects on net interest income and net income.  See "MANAGEMENT'S
DISCUSSION AND ANALYSIS OF CONSOLIDATED FINANCIAL CONDITION AND RESULTS OF
OPERATIONS - ASSET AND LIABILITY MANAGEMENT".

REGULATION

FIBM's banking subsidiaries are subject to extensive regulation under both state
and federal law.  The restrictions imposed by such laws and regulations could
limit the Company's discretion in operating its banks.  No assurance can be
given that existing laws and rules will not be amended or that new laws and
rules will not be adopted, the effect of which could be to adversely affect the
operations of the Company.  See "BUSINESS - REGULATION AND SUPERVISION".

MATERIAL BENEFIT TO SELLING SHAREHOLDER

The Selling Shareholder acquired nearly all of his stock in FIBM when it was 
incorporated in 1971, except for FIBM common stock acquired in the share 
exchange with CBS in 1993, although nearly all the CBS stock exchanged by the 
Selling Shareholder had been acquired on the incorporation of CBS in 1974. 
The acquisition price of the FIBM common stock owned by the Selling 
Shareholder is significantly less than the current minority appraised value 
of the FIBM common stock, which will be received by the Selling Shareholder 
upon sale of the Selling Shareholder's stock offered hereby. See "SELLING 
SHAREHOLDER" and "COMMON STOCK MARKET AND VALUATION INFORMATION". By selling 
FIBM stock to offerees hereunder, the Selling Shareholder will be able to 
obtain more favorable tax treatment for his sale proceeds than if FIBM 
redeemed his shares.

<PAGE>

                                USE OF PROCEEDS

Of the 65,693 shares of FIBM common stock to be offered for sale 
hereunder, 21,276 shares of common stock of the Selling Shareholder, or the 
portion thereof which the Selling Shareholder decides to sell,  will be 
offered for sale first, with all proceeds of such sale going to the Selling 
Shareholder.  After the stock offered for sale by the Selling Shareholder has 
been sold, 44,417 shares of common stock to be issued by FIBM will next be 
offered for sale, with all proceeds of such sale going to the Company, less 
expenses of this offering which will be paid by the Company.  The Company has 
no current specific plan for use of the proceeds it will receive from the 
offering, but it may apply some or all of the proceeds to the reduction of 
debt or to operating expenses. The Company is making this offering not to 
raise funds for the Company, but as a means to continue to offer stock for 
purchase by certain officers, directors (including advisory directors), and 
employees of the Company and by employee participants in the Company's 
Savings Plan.

                        DETERMINATION OF OFFERING PRICE

   
The offering price of FIBM common stock is based upon an appraisal of a 
minority block of the stock as of June 30, 1997 by Alex Sheshunoff & Co. 
Investment Banking ("Sheshunoff"), minus dividends paid since June 30, 1997. 
The appraisal concluded that the fair market value of a minority block of 
common stock in FIBM at June 30, 1997 is $95.00 per share.  Subtracting the 
dividend of $1.00 per share paid on July 21, 1997, the offering price of the 
stock has been set at $94.00 per share. A copy of the appraisal is attached 
as EXHIBIT B.
    

The appraisal takes into consideration the nature and history of the Company, 
the economic outlook in the Company's trade area and for the banking industry 
in general, the financial performance and condition of the Company, its future 
earnings and dividend  paying capacities, previous sales of FIBM stock, the 
size of the block of stock valued, the market price of selected comparable 
banking institutions, and other factors deemed relevant by the appraiser.
In preparing its appraisal, Sheshunoff reviewed financial information regarding
the Company's financial performance and condition for the three years ending
December 31, 1996 and the six months ending June 30, 1997, together with
Company projected income, asset growth, book value and dividends for the five
fiscal years ending December 31, 2001.  The appraiser did not independently 
verify the asset quality or financial condition of the Company.

Company management has reviewed the independent appraisal, including the stated
methodology of the independent appraiser and the assumptions used in the
preparation of the independent appraisal.  The board of directors and management
of the Company is relying upon the expertise, experience and independence of the
appraiser and is not qualified to determine the appropriateness of the
assumptions.

The appraisal is not a recommendation of any kind as to the advisability of
purchasing these shares.  In preparing the appraisal, Sheshunoff has relied
upon and assumed the accuracy and completeness of financial and statistical
information provided by FIBM.  Sheshunoff did not independently verify the
financial statements and other information provided by FIBM, nor did Sheshunoff
value independently FIBM's assets and liabilities.  The appraisal considers FIBM
only as a going concern and does not value the shares based upon a liquidation
or other restructuring of the Company.  Moreover, because the appraisal is based
upon estimates and projections of a number of matters which are subject to
change, the appraised market value of the common stock could decline below
$94.00 in the future.

COMMON STOCK

Each share of FIBM Stock is entitled to one vote in the election of directors
and in all other matters submitted to a vote of stockholders.  Accordingly,
holders of a majority of the shares of common stock entitled to vote in any
election of directors may elect all of the directors standing for election if
they choose to do so, subject to the rights of holders of the Preferred Stock
(see "Preferred Stock" below).  Voting for directors is non-cumulative.

Subject to the preferential rights of any preferred stock that may at the time
be outstanding, each share of FIBM Stock has an equal and ratable right to
receive dividends when, if and as declared by the Board of Directors out of
assets legally available therefor.  See "DIVIDEND RESTRICTIONS" below.  In the
event of a liquidation, dissolution or winding up of FIBM, the holders of FIBM
Stock will be entitled to share equally and ratably in the assets available for
distribution after payments to creditors and to the holders of any preferred
stock that may at the time be outstanding.

Holders of FIBM Stock have no conversion rights or preemptive or other rights to
subscribe for any additional shares of FIBM Stock or for other securities.  All
outstanding FIBM Stock is fully paid and non-assessable.

Montana corporate law provides that dissenting shareholders have dissenters'
rights with respect to mergers, consolidations, and plans of exchange.

DIVIDEND RESTRICTIONS

The holders of FIBM Stock will be entitled to dividends when, as and if declared
by FIBM's Board of Directors out of funds legally available therefor.  FIBM has
a loan agreement with its primary lenders which prohibits declaration or payment
of any dividends to common stockholders in excess of 33% of net income for the
immediately preceding year.  FIBM has also agreed with its primary lenders that
subsidiary banks will maintain ratios of tangible primary capital to tangible
primary assets not less than the ratios required by regulators or applicable law
or regulation, and that subsidiary banks will at all times maintain capital at
levels that the Federal Deposit Insurance Corporation ("FDIC") would categorize
as "Adequately Capitalized" or better under applicable regulations.  The loan
restrictions limit the funds available for the payment of dividends from the
Subsidiaries to FIBM and from FIBM to its shareholders.
   
Funds for the payment of dividends of FIBM are expected to be obtained 
primarily from dividends of FIBM's banking subsidiaries.  Under Montana 
banking law, FIB Montana may not declare dividends in excess of their 
respective net undivided earnings (as defined) less any required transfers to 
surplus, and may not declare a dividend larger than the previous two years' 
net earnings unless prior notice is given to the Montana Commissioner of 
Banking and Financial Institutions.  Under Wyoming banking law, FIB Wyoming 
may not declare dividends without meeting surplus fund requirements and may 
not, without the approval of the Wyoming Banking Commissioner, declare 
dividends in any one calendar year in excess of its net profits (as defined) 
in the current year combined with retained net profits of the preceding two 
years, less any required transfers to surplus or to a fund for the retirement 
of any preferred stock.

In addition,  federal regulatory agencies (e.g., the FDIC, OTS, and FRB) have 
authority to prohibit a bank under their supervision from engaging in 
practices which, in the opinion of the particular federal regulatory agency, 
are unsafe or unsound or constitute violations of applicable law.  For 
example, depending upon the financial condition of a bank in question and 
other factors, the appropriate federal regulatory agency could determine that 
the payment of dividends might under some circumstances constitute an unsafe 
and unsound practice.  Moreover, each federal regulatory agency has 
established guidelines for the maintenance of appropriate levels of capital 
for a bank under its supervision.  Compliance with the standards set forth in 
such guidelines could limit the amount of dividends which FIBM or any of its 
subsidiaries could pay. See "BUSINESS - REGULATION AND SUPERVISION".
    
Preferred stock of FIBM is senior to common stock with respect to dividends.
Before any dividends on common stock can be paid or declared and set apart for
payment, FIBM must:  (1) comply with all conditions and restrictions of any and
all series of preferred stock for which dividends are noncumulative; (2) pay, or
declare and set aside a sum sufficient for payment, of dividends, past and
current, on any and all series of preferred stock for which dividends are
cumulative; and (3) satisfy all accrued sinking fund obligations, if any, of any
and all series of preferred stock.

PREFERRED STOCK

The authorized capital stock of FIBM includes 100,000 shares of preferred stock
of which 20,000 shares have been designated as Noncumulative Perpetual Preferred
Stock (the "Preferred Stock").  The 20,000 shares of Preferred Stock were issued
in September, 1996 at a price of $1,000 per share, and are the only series of
preferred stock issued and outstanding.  The holders of Preferred Stock are
entitled to the following preferences, powers and special rights:  (i) in the
event of voluntary or involuntary liquidation, dissolution or winding up of the
affairs of FIBM, holders of Preferred Stock are entitled to receive $1,000 per
share before any payments to holders of common stock; (ii) holders of Preferred
Stock are entitled to one vote per share, with a required super majority vote of
66 2/3% of outstanding shares to take action, on the issuance of any stock
having dividend and liquidation rights in preference and priority to the
Preferred Stock and on the amendment of FIBM's articles of incorporation or the
Certificate of Designation of the Preferred Stock having an adverse affect on
the rights of holders of Preferred Stock; (iii) holders of Preferred Stock are
entitled to payment of specified dividends when and as declared by FIBM's board
of directors; (iv) holders of Preferred Stock are entitled to elect 2 directors
to FIBM's board of directors if full dividends are not paid for six quarters to
holders of the Preferred Stock, which right continues until full dividends have
been paid for four consecutive quarters.  The Preferred Stock is not convertible
and is not redeemable prior to 7 years from its issuance.

The Board of Directors is authorized, without approval of the holders of 
common stock, to provide for the issuance of additional preferred stock from 
time to time in one or more series in such number and with such designations, 
preferences, powers and other special rights as may be stated in the 
resolution or resolutions providing for such preferred stock.  The Board of 
Directors may cause FIBM to issue preferred stock with voting, conversion and 
other rights that could adversely affect the holders of the FIBM Stock or 
make it more difficult to effect a change of control of the Company.

In the event of any dissolution, liquidation or winding up of the affairs of
FIBM, before any distribution or payment may be made to the holders of common
stock of FIBM, the holders of preferred shares would be entitled to be paid in
full with the respective amounts fixed by the Board of Directors in the
resolution or resolutions authorizing the issue of such series, together with a
sum equal to the accrued and unpaid dividends thereon to the date fixed for such
distribution or payment.  After payment in full of the amount which the
preferred shareholders are entitled to receive, the remaining assets of FIBM
would be distributed ratably to the holders of the common stock.  If the assets
available are not sufficient to pay in full the amount so payable to the holders
of all outstanding preferred stock, the holders of all series of such shares
would share ratably in any distribution of assets in proportion to the full
amounts to which they would otherwise be respectively entitled.  The
consolidation or merger of FIBM into or with any other corporation or
corporations would not be deemed a liquidation, dissolution, or winding up of
the affairs of FIBM.

Preferred stock of FIBM is senior to common stock with respect to dividends.
See "DIVIDEND RESTRICTIONS" above.

RESTRICTIONS ON RESALE


Public resale of FIBM Stock by certain persons deemed to be affiliates or
control persons of the Company will be restricted pursuant to certain provisions
of Rule 144 promulgated under the Securities Act of 1933.  See "PRINCIPAL
HOLDERS OF VOTING SECURITIES".

Resale of FIBM Stock may be restricted pursuant to the Securities Act of 1933
and applicable state securities laws.  In addition, most shares of FIBM Stock
are subject to one of two shareholder's agreements.  Members of the Scott
Family, as majority shareholders of FIBM, are subject to a Shareholder's
Agreement (referred to herein as the "Scott Agreement").  The Scott Family,
under the Scott Agreement, has agreed to limit the transfer of shares owned by
members of the Scott Family to family members or charities, or with FIBM's
approval, to the Company's officers, directors, advisory directors, or to the
Savings Plan.

                                       12

<PAGE>
   
Shareholders of FIBM who are not Scott Family members (with the exception of 
13 shareholders (including the Savings Plan) who own 123,674 shares of 
unrestricted stock) are subject to a different Shareholder's Agreement 
(referred to herein as the "Shareholder's Agreement").  SEE EXHIBIT A HERETO. 
 Stock subject to the Shareholder's Agreement may not be sold or transferred 
by the shareholder without triggering FIBM's option to acquire the stock in 
accordance with the terms of the Shareholder's Agreement.  The Shareholder's 
Agreement grants FIBM the option to purchase the FIBM stock restricted 
thereby at the minority appraised value per share based upon the most recent 
quarterly appraisal available to FIBM less dividends paid since the end of 
the quarter for which the value of the stock has been determined in that 
appraisal.  FIBM is required under the Shareholder's Agreement to obtain, at 
its expense, an appraisal of FIBM shares of common stock as of the last day 
of each calendar quarter prepared by an unaffiliated firm qualified to make 
such an appraisal. The appraiser will take into account the minority, or 
non-controlling, size of the block of stock to be valued, which will result 
in an appraised value which is less than a majority, or controlling, block of 
stock.  FIBM's purchase option arises in any of the following events:  (1) 
the shareholder's intention to sell the stock, (2) the shareholder's death, 
(3) transfer of the stock by operation of law, (4) termination of the 
shareholder's status as a director, officer or employee of FIBM, and (5) 
total disability of the shareholder.  In addition, the Shareholder's 
Agreement allows FIBM to repurchase any of the FIBM stock acquired by the 
shareholder after January 1, 1994 if FIBM determines that the number of 
shares owned by the shareholder is excessive in view of a number of factors 
including but not limited to (a) the relative contribution of the shareholder 
to the economic performance of the Company, (b) the effort being put forth by 
the shareholder, and (c) the level of responsibility of the shareholder. This 
restriction is intended to allow FIBM to reduce or eliminate a shareholder's 
stock ownership in FIBM in circumstances where the shareholder's employment 
role, responsibility or contribution to the success of the Company has been 
reduced or has declined.  To date, FIBM has not exercised its rights under 
this restriction.
    
Any of the FIBM common stock purchased through this offering, except for 
purchases through the Savings Plan, will be subject to the terms of the 
Shareholder's Agreement, and the purchaser will be required to accept in 
writing the terms and conditions of the Shareholder's Agreement.  FIBM has 
not sought an opinion of counsel regarding the validity or enforceability of 
any of the restrictions contained in the Shareholder's Agreement. Enforcement 
of the excess stock ownership restriction contained in the Shareholder's 
Agreement may be an unsettled issue, since no Montana legal authority exists 
with respect to the enforceability of such a restriction.  Initial 
determination as to any claimed violation of the Shareholder's Agreement will 
be made by FIBM, although any final determination may be made in court. 

Purchases of FIBM common stock made through the Savings Plan will not be
restricted by the Shareholder's Agreement, due to requirements of ERISA and the
Internal Revenue Code.  However, since the Savings Plan does not allow
distributions in kind, any distributions from an employee's account in the
Savings Plan will allow, and may require, the Savings Plan trustee to sell the
FIBM stock.  While FIBM has no obligation to repurchase the stock, it is
possible that FIBM will repurchase FIBM stock sold out of the Savings Plan.  Any
such repurchases would be upon terms set by the Savings Plan trustee and
accepted by FIBM.

The restrictions on resale of FIBM common stock will greatly limit the
marketability of the stock, and the appraised value price prescribed under the
Shareholder's Agreement may be less than the purchase price paid by a
shareholder for the stock and may be less than the actual value of the stock.

                                 DIVIDEND POLICY

It is the policy of FIBM to pay a dividend to all common shareholders 
quarterly. Dividends are declared and paid in the month following the 
calendar quarter and the amount has been determined based upon a percentage 
of net income for the calendar quarter immediately preceding the dividend 
payment date.  Dividends for the second and third quarters of 1995 were 
calculated at the rate of 25% of net income.  Prior to July 1995, 20% of net 
income was paid quarterly as a dividend. Effective with the dividend for the 
fourth quarter of 1995 paid in January 1996, the dividend was increased to 
30% of quarterly net income.  The Board of Directors of FIBM has no current 
intention to change its dividend policy, but no assurance can be given that 
the Board may not, in the future, limit or eliminate the payment of dividends.

(1) Includes dividends paid on 19,518 shares of stock sold pursuant to this 
    offering to certain officers, directors, and advisory directors of the 
    Company.
    

Payment of dividends to common shareholders by FIBM is dependent upon the
ability of FIBM's subsidiaries to pay dividends to FIBM.  Payment of dividends
by FIBM's subsidiaries are subject to restrictions imposed by state and federal
banking laws and by federal and state regulatory agencies.  Payments of
dividends by the banks to FIBM and by FIBM to its shareholders are subject to
restrictions imposed by FIBM's primary lenders and by state and federal
regulatory agencies.  See "DESCRIPTION OF CAPITAL STOCK - DIVIDEND
RESTRICTIONS".  Payment of future dividends is at the discretion of FIBM's Board
of Directors and will also depend upon, among other things, the Company's
earnings, financial condition, capital requirements, extent of indebtedness,
regulatory limitations, and contractual restrictions with respect to the payment
of dividends.  There can be no assurance that FIBM will continue to pay
dividends.


                   COMMON STOCK MARKET AND VALUATION INFORMATION

The common stock of FIBM is not actively traded, and there is no established
public trading market for the stock.  There have been no sales of FIBM Stock 
in the last three years other than sales by the Scott Family and redemptions 
of stock by FIBM under the Shareholder's Agreement.
   
There is only one class of common stock, with 93.8% of the shares restricted 
by agreement and 6.2% held by 13 shareholders which are unrestricted.  FIBM 
has the right of first refusal to purchase the restricted stock at the 
minority appraised value per share based upon the most recent quarterly 
appraisal available to FIBM less dividends paid.  All unrestricted stock is 
purchased and sold at a price per share that is acceptable to the shareholder.
No trades of unrestricted stock within the past three years are known to FIBM.
FIBM has no obligation to puchase unrestricted stock, but has historically
purchased such stock in order to reduce the amount of its stock not subject to
transfer restrictions.
    
FIBM has no obligation, by contract, policy or otherwise, to purchase stock 
from any shareholder desiring to sell, or to create any market for the stock. 
Historically, it has been the practice of FIBM to repurchase common stock to 
maintain a shareholder base with restrictions on sale or transfer of the 
stock. See "RESTRICTIONS ON RESALE OF FIBM STOCK". In the last three calendar 
years (1994-1996) FIBM has redeemed a total of 52,066 shares of common stock, 
all of which was restricted by the Shareholder's Agreement. FIBM has redeemed 
the stock at the price determined in accordance with the Shareholder's 
Agreement. FIBM has no present intention to change its historical practice 
for redemption of stock, but no assurances can be provided that FIBM will not 
change or end its practice of redeeming stock. Furthermore, FIBM redemptions 
of stock are subject to corporate law and regulatory restrictions which could 
prevent stock redemptions.

considered by the appraiser in determining an appraised value for FIBM common 
stock, and the conditions, assumptions and limitations of the appraisal.  A 
copy of the June 30, 1997 appraisal is attached as Exhibit B to this Prospectus.

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS
                  (Dollars in thousands, except per share data)

   
    
GENERAL
The profitability of FIBM is primarily dependent on the net interest income of
its subsidiary banks.  Net interest income is the difference between the bank's
interest and dividend income on interest-earning assets (principally loans and
investment securities) and interest expense on interest-bearing liabilities and
borrowings.  Net income is also affected by the quality of its loan portfolio
and related provisions for loan losses, as well as the amount of non-interest
income, including loan fees, service charges and other fees, and non-interest
expenses.  Operating results of FIBM's banking operations are also affected, to
a lesser extent, by the type of lending, fixed rate versus adjustable or short-
term, each of which has a different rate and fee structure.  Operating expenses
of FIBM's banking operations principally consist of employee compensation,
occupancy expenses, furniture and equipment expenses and other general and
administrative expenses.

FIBM generates its income from (1) dividends received from its bank
subsidiaries, (2) undistributed earnings of subsidiaries, (3) management fees
charged to subsidiaries, (4) net data processing income, and (5) other income,
principally federal income tax benefits.  In 1996, 69%, 14%, 6%, 7% and 4% of
FIBM's income was generated by each of the above five sources, respectively.

FIBM's net income is also affected by the profitability of its data processing
division.  Income of the data division includes data service fees for item
processing, ATM services, and bank data processing services, including general
ledger, investment securities, loans, deposits and asset/liability management.
Expenses of the data division are primarily employee compensation, equipment
maintenance and depreciation, leased telephone lines and supplies.

To a lesser extent, FIBM's net income is also affected by the profitability of
its trust operations.  Income of FIBM's trust operations are the result of trust
administration fees charged to trust customers.  Expenses of FIBM's trust
operations are principally employee compensation and related benefits, and other
general administrative expenses.

CAUTION:  FORWARD LOOKING STATEMENTS

This Prospectus contains forward-looking statements within the meaning of 
Section 21E of the Securities Exchange Act of 1934, as amended, which are 
subject to the safe harbor provisions created by that statute.  A 
forward-looking statement may contain words such as "will continue to be", 
"will be", "continue to", "expect to", "anticipates that", "to be", or "can 
impact". Management cautions that forward-looking statements are subject to 
risks and uncertainties that could cause the Company's actual results to 
differ materially from those projected in such forward-looking statements.  
These risks and uncertainties include, but are not limited to, the following: 
(i) the effect of changes in laws and regulations, including federal and 
state banking laws and regulations, with which the Company and its banking 
subsidiaries must comply, the cost of such compliance, and the potential 
material adverse effects if the Company or any of its banking subsidiaries 
were not in substantial compliance either currently or in the future as 
applicable; (ii) the effect of changes in accounting policies and practices, 
as may be adopted by the regulatory agencies as well as by the Financial 
Accounting Standards Board, or changes in the Company's organization, 
compensation and benefit plans; (iii) the effect on the Company's competitive 
position within its market area of increasing consolidation within the 
banking industry and increasing competition from larger "super regional" and 
other out-of-state banking organizations as well as non-banking providers of 
various financial services; (iv) the effect of unforeseen changes in interest 
rates; and (v) the effects of changes in the business cycle and downturns in 
the local, regional or national economies.

ASSET AND LIABILITY MANAGEMENT

The primary objective of the asset/liability management process is to optimize
the net interest income while prudently managing balance sheet risks.
Specifically, these risks include interest rate risk, maintaining sufficient
levels of capital, and a sufficient level of liquidity to meet the needs of
depositors and borrowers.  Fundamental to most risk management decisions are the
inherent tradeoffs between risk reduction and Company profitability.  In certain
circumstances, a measured amount of interest rate sensitivity in the balance
sheet may produce an improved level of earnings for the Company.  Thus, it is
not the intent of the Asset/Liability Committee (ALCO) to eliminate interest
rate risk.  Rather, the Company attempts to understand the level of risk
accompanying its decisions and to monitor and manage these risks.

The ability to optimize the net interest income is largely dependent upon the
achievement of an interest rate spread which can be managed during fluctuations
of prevailing market interest rates.  Interest rate sensitivity is a measure of
the extent to which net interest income will be affected by market interest
rates over a period of time.  Interest rate sensitivity is related to the
difference between amounts of interest earning assets and interest bearing
liabilities which either reprice or mature within a given period of time.  The
difference is known as interest rate sensitivity "gap".

<PAGE>

The declining interest rate environment FIBM experienced in the early 1990's
provided for growth in net interest income as the Company's funding costs
declined, which improved the spread realized between the yields on assets and
the cost of funds.  This factor, along with loan volume growth, has provided the
Company with favorable interest margins.  In anticipation of interest rates
rising during 1994, and in order to protect its net interest margin, FIBM
undertook actions to promote the lengthening of deposit maturities and the
generation of variable rate loans.  No swaps, financial futures or options
contracts have been utilized by the Company.  Interest earning assets maturing
or repricing within one year at December 31, 1996 provide some cushion to the
net interest margin when interest rates are flat or rising.

FIBM uses interest sensitivity "gap" analysis, income statement simulation
models, and, to a limited extent, duration analysis (including estimation of
borrower prepayment options) to evaluate the potential effects of changing
interest rates on the net interest margin of the subsidiary banks.  By specific
policy, FIBM will attempt to maintain a mix of earning assets and deposits in
the one year time period, such that no more than 5% of the net interest margin
will be at risk should interest rates rise or fall 1%.  In evaluating exposure
to interest rate movements, Management does not view the gap amounts as
presenting an unusually high risk potential, although no assurances can be given
that FIBM is not at risk in the event of rate increases or decreases.  Also,
certain assets have features which restrict changes in interest rates on a
short-term basis as well as over the life of the asset.  In the event of a
change in interest rates, prepayment of assets and deposit outflows would likely
deviate significantly from historical or expected levels.  The rate gap set
forth in the table above fails to consider the interest rate sensitivities of
those asset and liability accounts.  It is recognized that a rising rate
environment may decrease the ability of many borrowers to service their debt.
Management cannot provide any assurance as to what the actual affect of changes
in interest rates will be on FIBM's interest margin.

The ALCO attempts to keep informed as to the inherent tradeoffs resulting from
risk elimination and profitability objectives.


LIQUIDITY

FIBM's ALCO has established specific policies and procedures for managing
existing liquidity levels and has also developed contingency plans to address
potential liquidity needs.  The Company's current liquidity position is
supported in large part through core deposits generated from the Company's
banking offices and from a high quality investment portfolio.

FIBM's current investment portfolio contains a mix of maturities which provide a
structured flow of maturing and reinvestable funds that can be converted to
cash, should the need arise.  Maturing balances in the loan portfolio also
provide options for managing cash flows.  The ability to redeploy these funds is
an important source of intermediate to long-term liquidity.
   
Backup sources of liquidity are provided by Federal funds lines carried with
both upstream and downstream correspondent banks.  Additional liquidity could be
generated through borrowings from the Federal Reserve Bank of Minneapolis, of
which FIB Montana is a member.  Additionally, liquidity and/or matched funding
can be obtained from the Federal Home Loan Bank of Seattle, of which FIB
Montana and FIB Wyoming are members.  At June 30, 1997, the Company had 
$8.8 million available on its revolving term loan.
    
The Company is not aware of any current recommendations by the regulatory
authorities which, if they were to be implemented, would have a material effect
on the Company's liquidity, capital resources or results of operations.

FINANCIAL CONDITION AT JUNE 30, 1997

ACQUISITION ACTIVITY
On October 1, 1996, the Company purchased all of the outstanding capital 
stock of First Interstate Bank of Wyoming, N.A. and First Interstate Bank of 
Montana, N.A.; and, on December 18, 1996 , acquired all of the outstanding 
capital stock of Mountain Bank of Whitefish (collectively, "the acquired 
banks").  The transactions were accounted for under purchase accounting 
rules.  Goodwill, representing the excess of cost over net assets acquired, 
is being amortized using the straight-line method over periods of 15 to 25 
years.

EARNING ASSETS
Earning assets of $1.9 billion at June 30, 1997 were $96.2 million, or 5%, 
higher compared to December 31, 1996 primarily due to growth in loan volume. 
The mix of earning assets changed little from December 31, 1996 with net 
loans comprising approximately 77%, held-to-maturity investment securities 
comprising approximately 17% and interest bearing deposits, 
available-for-sale investment securities and federal funds sold comprising 
the remaining 6%.

LOANS.  All major categories of loans showed increases in volumes from 
December 31, 1996 due to continued strong economic conditions in the 
communities served by the Company's banking subsidiaries and some seasonal 
increases, particularly in agricultural lending, following traditional 
paydowns during the fourth quarter.  Growth in net loans of 7% during the 
first six months of 1997 is slightly lower than the 8.1% growth rate 
experienced during the same period of 1996 indicating a slight slowing in the 
economy that has been attributed to a slowing of consumer borrowing as 
consumer debt rises.

INVESTMENT SECURITIES.  The Company manages its investment portfolio within 
established policies which provide for the management of interest rate 
sensitivity risks, to meet earning objectives, to provide ample liquidity and 
to provide adequate collateral to support deposit and repurchase agreement 
activities.  Cash proceeds from maturities, sales and principal payments 
during the first six months of 1997 were generally reinvested in 
held-to-maturity investment securities or used to provide additional 
liquidity to fund increases in other earning assets.

FEDERAL FUNDS SOLD.  Federal funds sold balances increased approximately $14 
million from December 31, 1996 as the Company's banking subsidiaries funded 
the cash requirements of correspondent banks.  Average federal funds sold 
balances during the first half of 1997 of $25,753 and during 1996 of $25,462 
showed only slight variance.

FUNDING SOURCES
The Company utilizes various traditional funding sources to support its 
earning asset portfolio including deposits, borrowings, federal funds 
purchased and repurchase agreements.

DEPOSITS.   Overall, total deposits decreased slightly from December 31, 1996 
to June 30, 1997.  Decreases in non-interest bearing deposits of $32.0 
million during the first six months of 1997, were partially offset by 
increases in interest-bearing deposits of  $25.8 million during the same 
period.  The Company historically has experienced similar seasonal cycles in 
overall deposit growth during the first half of the year.

FEDERAL FUNDS PURCHASED AND OTHER BORROWED FUNDS.  Federal funds purchased 
for one day periods and other borrowed funds consisting primarily of 
short-term borrowings from the Federal Home Loan Bank increased $72.7 million 
from December 31, 1996 to June 30, 1997. The increased borrowings were the 
result of funding requirements related to increases in loans and Federal 
funds sold during the first half of 1997.

LONG TERM DEBT.  During the first half of 1997, the Company reduced its 
long-term indebtedness by $8.5 million or 14%.  Payments of  approximately 
$8.4 million on the Company's revolving term debt were funded by earnings of 
the Company's banking subsidiaries.

FINANCIAL CONDITION AT DECEMBER 31, 1996

FIBM's earning assets include a mix of 76.8% in loans and 22.5% in investment
securities, with the balance in short term Federal funds and an interest-bearing
deposit in another bank.

GENERAL.  During 1996, total assets increased $712,622 or 52.7% from $1,351,215
at December 31, 1995 to $2,063,837 at December 31, 1996.

The increase in consolidated assets was largely the direct result of
acquisitions which occurred in the last quarter of 1996.  FIB Montana, NA and
FIB Wyoming, NA with consolidated assets of approximately $276,000 and $324,000,
respectively, at the transaction date were acquired on October 1, 1996.  FIB
Whitefish with total assets of approximately $71,000 at the transaction date was
acquired effective December 18, 1996.  Exclusive of acquired assets, total
assets at December 31, 1996 increased approximately $45,000 or 3.3% from
December 31, 1995.

INVESTMENT SECURITIES.  FIBM manages its investment portfolio within established
policies which seek to manage  interest rate sensitivity risks, to meet earnings
objectives, to provide sufficient liquidity and to provide adequate collateral
to support deposit and repurchase agreement activities.  There are no
significant concentrations of investments as of December 31, 1996 (greater than
10% of stockholders' equity) in any individual security issuer, except for the
U.S. Government and U.S. Government-sponsored agencies.
    
Increases in investment securities associated with the acquisitions of FIB
Montana, NA, FIB Wyoming, NA and FIB Whitefish in 1996 aggregated approximately
$100,000.  The investment policy does not permit the use of portfolio securities
for speculative purposes, including, but not limited to, gains trading (selling
investment assets prior to maturity in order to recognize market appreciation,
while continuing to hold securities which have unrealized market losses).
Management has, however, identified certain investment securities as available-
for-sale which, in the event of changing market conditions, may be sold prior to
their stated maturities.

The investment portfolio, representing 22.5% of earning assets, is well
diversified.  Approximately 95.5% of the investment portfolio is at fixed rates
of interest, with the remaining portion at variable rates, of which most are
issues of agencies of the U.S. government.  U.S. treasury securities comprise
53.2% of the investment portfolio, with 30% maturing within one year.  No U.S.
Treasury securities held at December 31, 1996 have maturities beyond five years.
An additional 35.9% of the investment portfolio is comprised of obligations of
U.S. government agencies.  35% of the agency securities mature within one year,
an additional 38% within five years, an additional 7% within ten years, and the
remaining 20% in over ten years.  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.  Tax exempt investments in issues of state,
county and municipal entities represent 4.9% of the investment portfolio, and
are all at fixed rates with slightly over two-thirds of the securities maturing
within five years.  The remaining 6.0% of the investment portfolio is
principally comprised of a mix of corporate, mortgage backed, and other
securities with varying maturities.  It is currently management's intent to hold
most investment securities to maturity.

LOANS.  The loan portfolio is well diversified, including a mix of commercial,
consumer, agricultural and real estate loans as well as a mix of fixed and
variable rate loans.  Approximately 67% of total loans are at fixed rates.
34.3% of the Company's loan portfolio is comprised of commercial loans, of which
54% are at adjustable rates and 46% are at fixed rates.  35.4% of the loan
portfolio is direct and indirect consumer loans and credit card loans, over 90%
of which are at fixed rates. Approximately 94% of fixed rate consumer loans are
for terms of less than five years.  Agricultural loans comprise 10.4% of the
portfolio, of which 59% are at adjustable rates.  20.0% of the loan portfolio is
comprised of real estate loans, 77% of which are at fixed rates.  Two-thirds of
fixed rate real estate loans mature within five years.

Loan increases related to the acquisitions in 1996 aggregated approximately
$401,000 (net of allowances for possible loan losses aggregating $10,553).
Other increases in net loans during 1996 totaled approximately $91,500 or an
increase of over 10% from consolidated net loans of $855,207 at December 31,
1995.  There were increases in loan volumes in all major categories of loans in
1996.  Increases in loan demand are attributed to continued economic growth in
the communities served by FIBM's bank subsidiaries.

Unlike residential mortgage loans and consumer installment loans, which
generally are made on the basis of the borrower's ability to make repayment from
his or her employment and other income, and which are secured by real property
whose value tends to be more easily ascertainable, commercial business loans are
of higher risk and typically are made on the basis of the borrower's ability to
make repayment from the cash flow of the borrower's business.  As a result, the
availability of funds for the repayment of commercial business loans may be
substantially dependent on the success of the business itself. Further, the
collateral securing the loans may depreciate over time, may be difficult to
appraise and may fluctuate in value based on the success of the business.  The
Company attempts to limit these risks by employing underwriting and
documentation standards contained in written loan policies and procedures.
These policies and procedures are reviewed on an ongoing basis by management and
adherence to stated policies are monitored by credit administration.

PROBLEM AND CLASSIFIED LOANS.  Federal regulations require that each financial
institution classify its assets on a regular basis.  In addition, in connection
with examinations of insured institutions, examiners have authority to identify
problem loans and, if appropriate, classify them.  There are three
classifications for classified loans; "substandard", "doubtful", and "loss".
Substandard loans have one or more defined weaknesses and are characterized by
the distinct possibility that the insured institution will sustain some loss if
the deficiencies are not corrected.  Doubtful loans have the weaknesses of
substandard assets with the additional characteristic that the weaknesses make
collection or liquidation in full on the basis of currently existing facts,
conditions and values questionable, and there is a high probability of partial
loss.  A loan classified loss is considered uncollectible and of such little
value that continuance as an asset of the institution is not warranted.  Problem
loans include classified loans and another category designated "special mention"
maintained for loans which do not currently expose an insured institution to a
sufficient degree of risk to warrant classification as substandard, doubtful or
loss.  Loans classified as substandard or doubtful usually require the
institution to establish general allowances for loan losses.  If a loan or
portion thereof is classified loss, the insured institution must either
establish specific allowances for loan losses in the amount of 100% of the
portion of the loan classified loss, or charge-off such amount.

Exclusive of assets classified loss and which have been fully reserved or
charged-off, FIBM's problem loans at December 31, 1996 consisted of $24,966 of
loans classified as special mention, $19,994 of loans classified as substandard
and $4,585 of loans classified as doubtful.

There are no loans classified as loss, doubtful, substandard, or special mention
that have not been disclosed above that represent or result from trends or
uncertainties which management reasonably expects will materially impact future
operating results, liquidity, or capital resources, or represent material
credits about which management is aware of any information which causes
management to have serious doubts as to the ability of such borrowers to comply
with the loan repayment terms.

The provision for loan losses provides a reserve (the allowance for loan losses)
to which loan losses are charged as those losses become evident. Management of
the banks determine the appropriate level of the allowance for loan losses on a
quarterly basis utilizing a report containing loans with a more than normal
degree of risk.  This report is the by-product of an ongoing loan review
process, the purpose of which is to determine the level of credit risk within
the portfolio and to ensure proper adherence to underwriting and documentation
standards.  Utilizing this report, a specific portion of the reserve is
allocated to those loans which are considered to represent significant exposure
to risk.  In addition, estimates are made for potential losses on all other
loans, not specifically reviewed, based on historical loan loss experience and
other factors and trends. See summary of transactions affecting the allowance
for loan losses at page F-32, and management's discussion of results for the
second quarter of 1997 at page 29.
    
FUNDING SOURCES.  Earning assets are funded by various sources, each of which is
continuously monitored to ensure an appropriate level of liquidity to meet
customer demand and to support the Company's operating needs.  The primary
funding source is a broad and diversified base of core deposits gathered by its
twenty-eight banking offices in Montana and Wyoming.  Non-interest bearing
demand deposit accounts comprise 22.9% of total customer deposits.  Low cost
interest bearing demand and savings deposits comprise an additional 42.5% of
total deposits.  Higher cost certificates of deposit and IRA accounts comprise
the remainder (34.6%) of total deposits.  Large certificates of deposit, those
for $100 and over, represent only 7.3% of total deposits and 21.1% of total time
deposits.

Deposits increased $580,355 from $1,099,069 at December 31, 1995 to $1,679,424
at December 31, 1996.  Again, the increase in deposits was principally the
direct result of the acquisitions of FIB Montana, NA, FIB Wyoming, NA and FIB
Whitefish.  Aggregate additions to deposits on the respective acquisition dates
were approximately $524,000, of which approximately $365 were interest-bearing. 
The remaining increase of over $56,000 or approximately 5.1% of deposits at
December 31, 1995 is reflective of moderate growth in overall customer deposits
in the last half of 1996 following a seasonal slowdown in overall deposit growth
during the first half of the year.

CAPITAL.  A significant measure of the strength of a financial institution is
its shareholders' equity, which should expand in close proportion to asset
growth.  At December 31, 1996, shareholders' equity totaled more than $146
million or 7.08% of total assets, compared with $109.4 million or 8.09% at year
end 1995.  Although FIBM has achieved steady internal capital generation
throughout the past five years, it also issued $20 million of noncumulative
preferred stock in conjunction with acquisitions in 1996.  Stockholders' equity
to assets declined in 1996 as the result of acquisitions during the year.

                                       27

Risk based guidelines define a two tier capital framework.  Tier 1 capital
consists of common shareholders' equity less disallowed intangibles, while total
risk based capital consists of Tier 1 capital, the allowance for loan losses up
to 1.25% of risk adjusted assets and long-term subordinated debt.  Risk adjusted
assets are determined by assigning various levels of risk to different
categories of assets and off-balance-sheet activities.

RESULTS OF OPERATIONS FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 1997 AND 1996.

INCOME FROM EARNING ASSETS.  Income from earning assets was $41.2 million for 
the three month period ended June 30, 1997, as compared to $26.6 million for 
the same period in 1996.  The increase of $14.6 million or 55% resulted from 
increases in earning assets through internal growth and the bank acquisitions 
discussed previously.  Exclusive of income from the acquired banks, interest 
income for the three months ended June 30, 1997 increased approximately 13% 
from the same period in 1996.  Yields on average total earning assets during 
the second quarter of 1997 and 1996 were 8.81% and 8.90%, respectively.

For the six month periods ended June 30, 1997 and 1996, income from earning 
assets was $80.3 million and $52.9 million, respectively.  Approximately 84% 
of the increase is due to interest income of the acquired banks.  The yield 
on average total earning assets for the first six months of 1997 was 8.78% 
compared to 8.85% during 1996.

EXPENSE OF INTEREST BEARING LIABILITIES.  The Company's interest expense for 
the three months ended June 30, 1997 was $18.0 million, a $ 6.8 million or 
61% increase over the same period in 1996.  Interest expense of the acquired 
banks and additional interest costs to fund the acquisitions aggregated 
approximately $6 million during the second quarter and $10.6 million 
year-to-date.  The remaining increase was caused by higher levels of interest 
bearing liabilities, particularly federal funds purchased for one day periods 
and other borrowed funds.  The cost of total average interest bearing 
liabilities during the first six months of 1997 of 4.4% did not change from 
the same period in 1996.

PROVISION FOR LOAN LOSSES.  The balance of the provision for loan losses is 
maintained at a level that is, in management's judgment, adequate to absorb 
losses inherent in the loan portfolio given past, present and expected 
conditions.  The provision for loan losses increased $397 and $1,129 for the 
three and six month periods ended June 30, 1997, respectively, from the same 
periods in 1996.  A significant portion of these increases relate directly to 
the acquired banks, $353 for the three month period and $919 for the six 
month period.  The remaining increases are associated with growth in loan 
volumes and slight deteriorations in the agricultural and consumer loan 
portfolios. Although non-performing and problem assets have shown some 
increases, the fundamental economies within the Company's markets remain 
strong.
    

   
    

   
OTHER OPERATING INCOME 
Exclusive of income attributable to the acquired banks, other operating 
income increased $261 or 5% during the second quarter of 1997 and decreased 
less than 1% during the six months ended June 30, 1997 compared to the same 
periods in the prior year.  Trust and data division revenues contributed to 
the increase in other operating income during the second quarter, 
contributing an additional $121 of income primarily due to increases in 
number of customers and transaction volumes.  Year-to-date trust and data 
revenues, however, show declines from the same period last year due to 
non-recurring accrual adjustments made during January 1996.  Service charges 
on deposit accounts also contributed to the overall increase in other income, 
up 5% for the quarter and year-to-date.

OTHER OPERATING EXPENSES 
Overall, quarter-to-date and year-to-date other operating expense increased 
approximately 55% from the same periods in the prior year.  Expenses incurred 
directly by the acquired banks aggregated approximately $3.6 million for the 
three months ended June 30, 1997 and $8.1 million for the six months ended 
June 30, 1997.  In addition to the direct other operating expenses incurred 
by the acquired banks, other operating expenses of the holding company and 
other banking subsidiaries increased, particularly in the operations and data 
divisions, due to the additional costs associated with  providing support 
services to the acquired banks.

SALARIES AND BENEFITS EXPENSE.  Salaries and benefits expense of $18 million 
for the six months ended June 30, 1997 increased 55% over the same period in 
1996. Salaries and benefits expenses for the three month period ended June 
30, 1997 showed a similar increase over the same period in 1996.  A 
significant portion of the quarter-to-date and year-to-date increases are 
attributable to the acquisitions and increased staffing levels necessary to 
provide operational and other support functions to the acquired banks.  The 
remaining increases are primarily inflationary in nature.

FURNITURE, EQUIPMENT AND OCCUPANCY EXPENSE.  Exclusive of increases directly 
related to the acquired banks, occupancy, furniture and equipment expenses 
increased approximately $255 or 10% during the three month period ended 


                                       29

    

<PAGE>

   
June 30, 1997 and $654 or 14% for the six month period ended June 30, 1997. 
Increases are principally due to increased depreciation on data processing 
equipment upgrades occurring during the second half of 1996 and the first 
half of 1997 and the continuing upgrades and expansion of the Company's 
micro-computer and ATM networks.

OTHER EXPENSES.  Other expenses increased $2.6 million for the three months
ended June 30, 1997 compared to the same period in the prior year and $5.1
million for the six months ended June 30, 1997 compared to the same period in
the prior year.  Of these increases, $1.2 million and $2.9 million for the three
and six month periods, respectively, relate directly to the acquired banks.  The
remaining quarter-to-date and year-to-date increases from the previous year are
principally due to increases in advertising and public relations costs,
additional legal and professional costs, and increases in postage, supply and
telephone expenses.

Exclusive of expenses directly related to the acquired branches, advertising and
public relation expenses for the three and six month periods ending June 30,
1997 were approximately $229 higher than the same periods in 1996.  These
increases are attributable to budgeted increases in advertising expense of
approximately $109 for the first half of 1997 combined with fluctuations in the
timing of public relation events in the current year compared to 1996.

Legal and professional expenses increased $367 during the three months ended
June 30, 1997 compared to the same period in the previous year and $634 during
the first half of 1997 compared to the first half of 1996.  Increases of $300
and $484, not directly related to the acquired banks, are due principally to
consulting fees associated with revision of the Company's employee job
evaluation system and accruals for financial planning activities.

Office supply, postage and telephone expenses increased $273 during the second
quarter and $588 year-to-date compared to the same periods in 1996, exclusive of
expenses incurred by the acquired banks.  These additional expenses are
primarily due to increased costs resulting from growth in the Company's customer
deposit base.

The above increases in other expense were offset by decreases in royalty fees of
$151 during the first half of 1997 due to the termination of a franchise
agreement with First Interstate Bancorp during May 1996.

Other quarter-to-date and year-to-date variances in other expenses from the
previous year are not considered individually significant.
    

   
    

RESULTS OF OPERATIONS FOR YEARS ENDED DECEMBER 31, 1996, 1995, AND 1994

NET INCOME.  1996 was another excellent year for the Company.  For the eighth
consecutive year, the Company exceeded all of its prior earnings records,
recording  net income of $21,243 in 1996, which topped 1995 net income of
$17,337 by $3,906 or 22.5%.  Net income in 1995 was up $1,603 or 10.2% from 1994
earnings of $15,734.  The increases in 1996 and 1995 were due in large part to
the acquisitions of FIB Montana, NA and FIB Wyoming, NA at the beginning of the
fourth quarter of 1996 and the acquisition of Citizens BancShares, Inc. ("CBI")
and First Park County Bancshares, Inc. ("FPCBI") which occurred effective
January 3, 1995 and May 19, 1995, respectively.  The additional consolidated
earnings as a direct result of the acquisitions in both years were partially
offset by lower short-term investment income and higher interest expense of FIBM
as a result of funding of the acquisitions.

NET INTEREST INCOME.  Net interest income is the largest source of the Company's
operating income.  Net interest income increased to $67,906 in 1996, up $10,882
or 19.1% from 1995 net interest income of $57,024.  1995 net interest income was
$5,245 higher than 1994 net interest income of $51,779, an increase of 10.1%.

Substantially all of the $10,882 increase in net interest income in 1996 was the
result of increases in volume which were due in large part to the acquisitions
of FIB Montana, NA and FIB Wyoming, NA at the beginning of the fourth quarter. 
The acquisition of FIB Whitefish in mid-December, to a much lesser degree, also
contributed to the increase in net interest income in 1996.  The net interest
income of banks acquired in 1996 aggregated approximately $6,660, but was
partially offset by approximately $1,130 of interest expense of  FIBM in the
fourth quarter from increased senior indebtedness and new subordinated notes
issued to fund the acquisitions.

In 1995, approximately $4,000 of the increase in consolidated net interest
income resulted from the acquisitions of CBI and FPCBI.  Additional interest
expense of FIBM resulting from increased indebtedness to fund these acquisitions
partially offset the increased net interest margin in 1995 by approximately
$800.

</TABLE>

Note:  Because of the numerous simultaneous volume and rate changes during
the period analyzed, it is not possible to precisely allocate the changes
between volumes and rates.  For purposes of this table, changes which are not
due solely to volume changes or to rate changes have been allocated to these
categories based on the respective percent changes in average volume and average
rate as they compare to each other.
   
There have been no material changes in the information presented or in trends
evidenced thereby from December 31, 1996 to June 30, 1997.
    
The primary component of the year-to-year increases in net interest income is
the growth in the volume of earning assets.  As shown in the above table, net
interest income was significantly impacted by the increases in earning assets
associated with banking acquisitions in 1996 and 1995, coupled with steady
growth in average earning assets.  Net interest income in 1995 was also affected
by changes in interest rates, while rate changes in 1996 resulted in little
change in net interest income.  The net interest margin for 1996 of 5.16% is
only 3 basis points lower than 1995's margin of 5.19%.  The net interest margin
for 1995 is 15 basis points lower than 1994's margin of 5.34%.  The effect of
these changes in percentage margin on net interest income is shown in the above
table as the change due to rate.

Customer loan fees, included in interest income for financial reporting 
purposes, were $5,028 in 1996, up $958 or 23.5% from $4,070 in 1995.  Loan 
fees in 1995 were down $143 or 3.4% from $4,213 in 1994.  Customer loan fees 
included in 1996 and 1995 income associated with banking acquisitions were 
$136 and $131, respectively.  The decline in customer loan fees in 1995 was 
principally the result of reduced real estate loan processing in the first 
half of 1995, However, new real estate loans and refinancing of existing 
loans rebounded in the last half of 1995 and continued through 1996, 
resulting in an increase in real estate loan fees of $402 in 1996 of which 
only $31 was the result of acquisitions.  Loan fees for other categories of 
loans also increased in 1996 from 1995.  Agricultural loan fees increased 
$33, of which $10 was acquisition-related.  But the most significant 
increases were in commercial and consumer loan fees which contributed over 
half the overall increase in loan fees.

Maintaining steady growth in net interest income is one of the Company's 
primary objectives and is monitored by management through its asset/liability 
management process.  The Company has historically achieved this objective, in 
part, as a result of having the necessary systems, procedures, and products 
in place to manage and promote balance sheet growth, maintain a strong net 
interest margin and remain competitively priced.  Management believes the 
Company, as in the past, is well positioned to maintain its solid growth in 
net interest income.

PROVISION FOR LOAN LOSSES.  The provision for loan losses was $3,844 and 
$1,629 for the years ended December 31, 1996 and 1995, respectively, as 
compared to $1,344 in 1994.  Of the $2,215 increase in the 1996 loan loss 
provision, $500 is related to acquired banking locations.  The remaining 
increase of $1,715 from 1995 is principally associated with overall increases 
in loan volumes and a slight deterioration in agricultural and consumer 
lending loans.  Net chargeoffs as a percentage of average loans was .17% in 
1996, up slightly from .13% in 1995, and .14% of in 1994.  The allowance for 
loan losses as a percentage of loans increased to 2.02% at December 31, 1996 
from 1.74% and 1.83% at December 31, 1995 and 1994, respectively, in large 
part due to reserve balances of banks acquired.  Loan loss provisions and 
reserve levels are reflective of the levels of  problem and classified loans.

Total classified loans increased $7,892 or 47.3% to $24,579 at December 31, 
1996 from $16,687 at December 31, 1995.  Total problem loans increased 
$22,448 or 82.8% from $27,097 at December 31, 1995 to $49,545 at December 31, 
1996.  Total nonaccrual loans increased $3,190 or 87.8% between years to 
$6,822 at December 31, 1996.  These increases in levels of problem, 
classified, and nonaccrual loans are due to bank acquisitions in 1995 and 
1996, increases in outstanding loans, and the slight deterioration in the 
agricultural and consumer sector. Further discussion on loan quality and the 
allowance for loan losses is included later in this review in the PROBLEM AND 
CLASSIFIED LOANS section.

Management actively monitors local industry for strengths and diversity and 
unemployment levels, and evaluates its banking markets for their effects on 
its loan portfolio.  Although nonperforming and problem assets increased in 
1996, the fundamental economies within the Company's markets have remained 
strong. The loan loss provisions and current levels of loan loss reserves 
reflect management's evaluation of the risks inherent in the loan portfolio 
and local economic conditions.  Should a significant shift in economic trends 
and/or increased volumes of problem credits or charge-offs occur, such events 
would likely require increased loan loss provisions in the future.

NON-INTEREST INCOME.  Total noninterest income increased $5,163 to $23,927 
from $18,764 for the years ended December 31, 1996 and 1995, respectively.  
Of this increase, approximately $1,450 is attributed to acquisitions in 1996. 
 In 1995, total noninterest income was up $2,377 from $16,387 in 1994, of 
which approximately $719 is attributed to the CBI and FPCBI acquisitions in 
1995.

Revenue from fiduciary activities increased $542 to $3,161 in 1996 from 
$2,619 in 1995, due in part to $243 of additional revenues of the banks 
acquired in 1996, but also the result of fee increases that took effect at 
the end of 1994, more aggressive marketing of the Company's fiduciary 
services in 1995 and 1996, and increased market values of the trusts under 
management.

Revenues from data processing services increased $1,128 or 18.2% to $7,324 in 
1996 from $6,196 in 1995, which were up $1,450 or 30.6% from revenues of 
$4,746 in 1994.  The increase in data processing revenue is the result of 
increases in data processing customers and the resulting increase in 
transaction volumes. During 1996 and 1995, the Company's data processing 
division expanded its ATM network from 216 total ATM locations at the 
beginning of 1995 to 343 at December 31, 1995 and to 477 at December 31, 
1996.  Although future growth in data processing revenues is not assured, 
continued expansion of the Company's ATM network and, to a lesser degree, 
regular data processing services is expected to continue into 1997, although 
not at the rates experienced in 1996 and 1995. Increases in data processing 
revenues as the result of expansion of the Data Division's customer base have 
been offset by similar increases in operating expenses of the Data Division.  
On a pretax basis, data processing division revenues, net of its direct 
operating expenses for 1996, increased $324 or 19.4% from 1995, which was up 
$359 or 27.5% from 1994.  There were no increases in basic charges for data 
processing services in 1996 or 1995.

Service charges on deposit accounts increased $1,220 or 18.7% to $7,752 from 
$6,532 in 1995.  Of this amount, approximately $650 is attributable to 
banking acquisitions.  The remaining increase is primarily the result of 
increases in overdraft fees.  Other service charges, commissions and fees 
increased $322 in 1996, primarily the result of banking acquisitions during 
the year.

Other income more than doubled in 1996, increasing $1,927 from $888 in 1995 
to $2,815 in 1996.  Banks acquired in 1996 generated other income aggregating 
$135 in the last quarter of the year; however, the most significant component 
was from the sale of merchant credit card processing at a gain of $1,359 in 
December 1996.  The sale included alignment with a specialized merchant 
processing provider that enhances the Company's ability to compete in this 
highly specialized area.

NON-INTEREST EXPENSES.  Total non-interest expenses increased $7,417 to 
$53,395 for the year ended December 31, 1996 from $45,978 for the year ended 
December 31, 1995.  Approximately $6,375 of the increase relates to banking 
locations added as a result of the acquisitions.  The remaining increase of 
approximately $1,040 or 2.3%, is principally inflationary increases.  Total 
non-interest expenses increased $4,751 from $41,227 for the year ended 
December 31, 1994. Approximately $3,320 of the increase relates to banking 
locations added as a result of the CBI and FPCBI acquisitions, while an 
additional $651 relates to the addition of two new banking offices opened in 
Billings (December 1994) and Missoula (January 1995).  The remaining increase 
of $780 or 1.9% of 1994 expense is principally inflationary increases.  The 
following table lists significant operating expenses:

Data division expenses, which are included throughout the various categories 
above, increased in both years, principally related to increases in data 
processing volumes and expansion of the ATM network, and additional 
depreciation associated with upgrades of data processing equipment.  Total 
data processing expenses increased $1,133 or 16.9% to $7,487 in 1996 from 
$6,714 in 1995, and $1,224 or 22.3% from $5,490 in 1994.  FIBM acquired a 
small data service center in Helena, Montana during 1994.  FIBM has expanded 
the customer base of the new facility, and continues to process certain 
correspondent activity at the Helena location.  Increases in data division 
expenses in 1996 and 1995 were offset by increases in data division income.

Salaries and benefits were $27,531 and $23,694 for the years ended December 
31, 1996 and 1995, respectively, an increase of $3,837 in 1996.  
Approximately $1,850 of the increase in salaries and benefits directly 
relates to banks acquired, while a portion of the remaining increase relates 
to personnel increases indirectly the result of acquisitions, particularly in 
the banks' operation centers and the data division.  Other increases in 
salaries and benefits are primarily inflationary in nature.

In 1995, salaries and benefits increased $2,515 from $21,179 for the year 
ended December 31, 1994.  Approximately two-thirds of the 1995 increase in 
salaries and benefits ($1,689) related to the acquisitions of CBI and FPCBI, 
and the two new facilities opened in Billings and Missoula.  The remaining 
increase in salaries and benefits ($826 or 3.9%) was principally the result 
of inflationary increases and additional staffing of the data division in 
1995, including the purchase of the data processing facility in Helena in 
mid-1994.

Aggregate occupancy, furniture and equipment costs increased $1,594 or 17.4% 
to $10,754 in 1996 from $9,160 in 1995.  Added facilities included the six 
new banking locations in Montana (Kalispell, Great Falls, Cut Bank, 
Whitefish, Evergreen and Hamilton) as well as the three new banking locations 
in Wyoming (Casper, Laramie and Riverton).  1996 expenses directly related to 
these locations aggregated $671.  In addition, higher depreciation, 
maintenance and other costs associated with the major hardware and software 
upgrades in the data division that began in early 1996 were the primary 
reasons for additional increases in occupancy, furniture and equipment 
expenses aggregating $679.  The remaining increase in these expenses was less 
than $250 and only 2.7% of 1995 expense totals.

Occupancy expenses increased $370 or 10.4% to $3,916 in 1995 from $3,546 in 
1994, principally due to added facilities in Bozeman, Livingston, Gardiner, 
Billings, Missoula and Helena.  Similarly, furniture and equipment expenses 
increased $686 or 15.1% in 1995 as compared to 1994 due, in part, to the 
additional facilities in 1995, however, increased furniture and equipment 
expenses were also the result of higher maintenance and other costs 
associated with the significant growth in the ATM network supported by the 
Company's Data Processing Division.

Other real estate ("OREO") expense, including provisions for OREO are 
included in non-interest expenses, net of gains on sales of OREO.  In 1996, 
FIBM recorded net OREO income of $214 compared to net OREO income of $586 and 
$457 in 1995 and 1994, respectively, or an increase in non-interest expenses 
of $372 in 1996 and a reduction in noninterest expenses of $129 in 1995.   
These net variances in expense were primarily the result of fluctuations in 
gains on sales of OREO. OREO sales gains were $335, $527 and $578 in 1996, 
1995 and 1994, respectively. Negative provisions for OREO of ($21) and ($28) 
were recorded in 1996 and 1995, respectively, compared to a provision of $10 
in 1994.  Decreased provisions and the reversals recorded in 1996 and 1995 
are reflective of dispositions of properties at gains and reduced loss 
exposure on remaining unsold properties. Although expected to continue 
through liquidation of remaining OREO properties, gains on disposition of 
OREO properties are expected to decline as the numbers and value of 
properties held in OREO continue to decrease.  Continued decreases in 
properties held, reductions in loss provisions and gains on disposition of 
properties, however, are not assured should a shift in economic trends occur.

FDIC deposit insurance premiums decreased $1,122 to only $5 in 1996 as 
compared to a decrease of $881 or 43.9% in 1995.  The reduced insurance costs 
in 1996 and 1995 were the result of an FDIC rate reduction of over 80% that 
took effect in June 1995, followed by an additional decrease during 1996 due 
to reductions in rates assessed by the FDIC that virtually eliminated FDIC 
insurance premiums in 1996.  These cost reductions are also reflective of the 
Company subsidiaries' "well-capitalized" rating by the FDIC.  So long as 
FIBM's bank subsidiaries in Montana and Wyoming continue to fall into the 
"well-capitalized" category, they will be assessed the lowest premium rate.

Other expenses increased $2,736 to $15,319 in 1996 from $12,583 in 1995.  
This increase is due to higher subsidiary expenses resulting from the 
acquisitions in 1996, aggregating approximately $2,921 including additional 
goodwill amortization of $569.  FIBM also incurred additional other expenses 
in 1996 which were directly related to the acquisitions.  These increases 
were partially offset by a decrease in First Interstate royalty fees, which 
were discontinued in May 1996 after the Franchise Agreement was terminated.

In 1995, other expenses increased $2,190 to $12,583 from $10,393 in 1994. 
Approximately $1,727 of this increase is higher subsidiary expenses resulting 
from the acquisitions of CBI and FPCBI, including additional goodwill 
amortization of $422, and the additions of new facilities in Billings and 
Missoula.  Further, FIBM incurred more than $200 in additional other expenses 
in 1995 which were directly related to the acquisitions of CBI and FPCBI.  
Net of these items, the increase in other expense was $463 or 4.5% of expense 
in 1994.

INCOME TAX EXPENSE.  Total income tax expense increased $2,507 from $10,844 
for the year ended December 31, 1995 to $13,351 for the year ended December 
31, 1996.  Federal income tax expense of $11,516 in 1996 represented an 
effective tax rate of 33.3% compared to Federal income tax expense of $9,328 
in 1995 which was an effective rate of 33.1%.  State income tax expense of 
$1,835 in 1996 and $1,516 in 1995, applied only to pretax earnings of 
entities operating within the state of Montana, represent effective tax rates 
of 5.3% in 1996 and 5.4% in 1995. 

By comparison, total income tax expense for 1995 increased $983 from $9,861 
for the year ended December 31, 1994.  Federal income tax expense of $8,532 
for the year ended December 31, 1994 represented an effective tax rate of 
33.3%.  1994 Montana income tax expense was $1,329 or an effective tax rate 
of 5.2%.

                    (Dollars in thousands, except per share data)
FIBM
   
First Interstate BancSystem of Montana, Inc.  ("FIBM" and collectively with 
its subsidiaries, the "Company") is a bank and savings and loan holding 
company registered as a bank holding company under the Bank Holding Company 
Act of 1956 ("Act") and is registered as a savings and loan holding company 
under the Home Owners' Loan Act.  FIBM was incorporated as a Montana business 
corporation on March 15, 1971.  FIBM's primary business is that of managing 
its wholly owned subsidiaries, First Interstate Bank in Montana ("FIB 
Montana"), First Interstate Bank in Wyoming ("FIB Wyoming"), First Interstate 
Bank, fsb in Hamilton, Montana ("First Interstate, fsb"), and Commerce 
Financial, Inc. ("CFI").  FIB Montana has eighteen banking offices in thirteen 
Montana communities.  FIB Wyoming has nine banking offices in seven Wyoming 
communities.  First Interstate, fsb was opened as a de novo savings bank on 
December 12, 1996 and currently has only one banking office.
    
In addition to management of its subsidiaries, FIBM has a data processing 
division headquartered in Billings, Montana, which performs data processing 
services for FIBM's subsidiaries, and 35 non-affiliated financial 
institutions with 79 locations in Montana, Wyoming and Idaho.  The data 
processing division also provides ATM support for 138 financial institutions 
in Montana, Wyoming, Idaho, Colorado and North Dakota. 

In addition to being the sole shareholder, FIBM functions as a service 
organization for each of its subsidiaries.  FIBM provides advice, counsel and 
specialized services to its subsidiaries in connection with a wide range of 
banking and operating policies and activities.  These services include data 
processing, auditing, credit administration, planning coordination, 
marketing, human resources management, asset/liability management and 
investments.


                                        37

The profitability of FIBM is primarily dependent on the net interest income 
of its subsidiary banks.  Net interest income is the difference between the 
bank's interest and dividend income on interest-earning assets (principally 
loans and investment securities) and interest expense on interest-bearing 
liabilities and borrowings.  Net income is also affected by the quality of 
its loan portfolio and related provisions for loan losses, as well as the 
amount of non-interest income, including loan fees, service charges and other 
fees, and non-interest expenses.  Operating results of FIBM's banking 
operations are also affected, to a lesser extent, by the type of lending, 
fixed rate versus adjustable or short-term, each of which has a different 
rate and fee structure.  Operating expenses of FIBM's banking operations 
principally consist of employee compensation, occupancy expenses, furniture 
and equipment expenses and other general and administrative expenses. 

FIBM generates its income from (1) dividends received from its bank 
subsidiaries, (2) undistributed earnings of subsidiaries, (3) management fees 
charged to subsidiaries, (4) net data processing income, and (5) other 
income, principally federal income tax benefits.  In 1996, 69%, 14%, 6%, 7% 
and 4% of FIBM's income was generated by each of the above five sources, 
respectively.

FIBM's net income is also effected by the profitability of its data 
processing division.  Income of the data division includes data service fees 
for item processing, ATM services, and bank data processing services, 
including general ledger, investment securities, loans, deposits and 
asset/liability management. Expenses of the data division are primarily 
employee compensation, equipment maintenance and depreciation, leased 
telephone lines and supplies. 

To a lesser extent, FIBM's net income is also effected by the profitability 
of its trust operations.  Income of FIBM's trust operations are the result of 
trust administration fees charged to trust customers.  Expenses of FIBM's 
trust operations are principally employee compensation and related benefits, 
and other general administrative expenses.

Responsibility for the management of each Subsidiary is in its board of 
directors and in the officers elected by that board, notwithstanding the 
overall guidance by FIBM described above.

The Company has a revolving term loan with its primary lenders in the amount 
of $42,000 at December 31, 1996.  The available borrowing amount is reduced 
by $2,000 on a semi-annual basis commencing in June, 1997.  The loan is 
secured by a pledge of all the outstanding capital stock of the Company's 
bank subsidiaries.  In connection with the loan, the Company has agreed to 
certain restrictions dealing with, among other things, minimum capital and 
operating ratios, the sale or issuance of capital stock, and the maximum 
amount of dividends.

The Company has issued and outstanding a $20,000 subordinated term note, due 
in increasing annual principal payments beginning October 1, 2002, with final 
maturity on October 1, 2006.  The Company has Federal funds lines of credit 
with third parties amounting to $50,000, subject to funds availability.  The 
Company also has been approved for participation in the Federal Home Loan 
Bank Cash Management Advance Program for borrowings up to approximately 
$39,500.
   
FIB Montana is a general partner in two general partnerships which form a 
joint venture which owns the building in Billings, Montana in which the home 
office of FIBOC Montana and the offices of FIBM are located ("the Building"). 
The joint venture is the borrower under a term loan having an unpaid 
principal balance of $10,937 as of December 31, 1996, which is secured by a 
lien on the Building.  FIBM is a guarantor of the Building loan.
    
The Company is the licensee under a trademark license agreement granting it 
an exclusive, non-transferrable license to use the "First Interstate" name 
and logo in the states of Montana, Wyoming, North Dakota, South Dakota and 
Nebraska.

BUSINESS OF FIBM'S SUBSIDIARIES
   
FIB Montana is a Montana chartered bank originally incorporated in 1916, 
having its principal office in Billings, Montana.  FIB Montana currently has 
eighteen banking offices in thirteen Montana communities - Billings, Bozeman, 
Missoula, Hardin, Miles City, Colstrip, Livingston, Gardiner, Great Falls, 
Kalispell, Whitefish, Cut Bank, and Evergreen.  The present structure of FIB 
Montana began December 1, 1992, when FIBM merged its eight Montana subsidiary 
banks, which became a state/federal reserve member bank with eight offices. 
FIB Montana opened an additional banking office in Billings, Montana in 
December 1994, and an additional banking office in Missoula, Montana in 
January 1995.  Acquisitions in 1995 and 1996 and increased FIB Montana's 
banking offices to the current number of eighteen.

FIB Wyoming is a Wyoming chartered bank originally incorporated in 1893 and 
currently has nine banking offices in seven northern Wyoming communities 
- -Sheridan, Gillette, Greybull, Buffalo, Casper, Laramie and Riverton.  The 
present structure of FIB Wyoming was created on December 30, 1988, when FIBM 
merged its five Wyoming subsidiary banks which became a state non-federal 
reserve member bank with six offices. Acquisitions in 1996 increased FIB 
Wyoming's banking offices to nine. 
    
First Interstate, fsb is a nationally chartered savings bank with its only 
office located in Hamilton, Montana.  First Interstate, fsb was a de novo 
charter, and first opened for business on December 12, 1996.

   
    

FIBM's banking subsidiaries are each engaged in general commercial banking 
activities, including all types of demand and time deposits, trust services, 
and commercial, agricultural, real estate, personal and consumer loans.  The 
banks also provide such other services as are generally furnished by 
commercial banks located in the principal cities and towns of Montana and 
Wyoming.

CFI, FIBM's only nonbank subsidiary, was incorporated in 1978, principally to 
originate and broker secured real estate loans.  During the past five years, 
CFI's principal activity has been the liquidation of assets acquired through 
foreclosure actions by FIBM.

COMPETITION
   
The banking business in both Montana and Wyoming is highly competitive with 
respect to both loans and deposits. As of December 31, 1996, according to 
information compiled by management, the combined deposits for FIB Wyoming 
and FIB Wyoming, NA aggregate $601 million, or approximately 8% of Wyoming's 
total bank deposits, and rank third in total deposits for banking 
organizations doing business in Wyoming.  Two larger organizations, Norwest 
Corporation and Key Corporation, headquartered in Minneapolis, Minnesota and 
Cleveland, Ohio, respectively, controlled approximately 34% and 14% of 
Wyoming's total bank deposits, respectively.  At June 30, 1996, according to 
information compiled by management, the combined deposits of  FIB Montana, 
FIB Montana, NA, and FIB Whitefish aggregated $994 million, approximately 14% 
of Montana's total bank deposits as of  June 30, 1996, and rank second in 
total deposits for banking organizations doing business in Montana.  Two 
larger organizations, Norwest Corporation and First Bank System, Inc., both 
headquartered in Minneapolis, Minnesota, controlled approximately 18% and 13% 
of Montana's total deposits, respectively.  By virtue of their greater total 
capitalization, such institutions have substantially higher lending limits 
than FIBM's banking subsidiaries since legal lending limits to an individual 
customer are limited to a percentage of the bank's total capital accounts.  
The enactment of the Riegle-Neal Interstate Banking and Branching Efficiency 
Act of 1994 is expected to increase competition, particularly from larger, 
multi-state banks.  See "REGULATION AND SUPERVISION" below.  Additionally, 
savings and loan associations, credit unions, finance companies and other 
companies provide competing financial services.  Some non-bank competitors, 
including brokerage companies, operate with certain regulatory advantages.
    
In addition to competing with savings institutions, including savings and 
loan associations and credit unions, commercial banks compete with other 
financial markets for funds.  Yields on corporate and government debt 
securities and other commercial paper affect the ability of commercial banks 
to attract and hold deposits.  Commercial banks also compete for available 
funds with money market instruments.  During past periods of high interest 
rates, money market funds have provided substantial competition to banks for 
deposits and they may continue to do so in the future.

REGULATION  AND SUPERVISION

GENERAL

Bank holding companies, commercial banks and savings banks are subject to 
extensive regulation under both federal and state law.  Any change in 
applicable law or regulation may have a material effect on the business and 
prospects of the Company.

As a bank holding company, FIBM is subject to the supervision of and 
regulation by the Federal Reserve Board ("FRB") under the Bank Holding 
Company Act of 1956. Also, as a savings and loan holding company, FIBM is 
subject to the supervision of and regulation by the Office of Thrift 
Supervision ("OTS").
   
First Interstate, fsb is subject to the supervision of, and regular 
examination by, the OTS.  FIB Wyoming is subject to the supervision of, and 
regular examination by, the Federal Deposit Insurance Corporation ("FDIC") 
and the State of Wyoming.  FIB Montana is subject to the supervision of, and 
regular examination by, the FRB and the State of Montana.  The FDIC insures 
the deposits of  FIBM's subsidiary banks to the current maximum of $100,000 
per depositor.
    
The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the 
"Interstate Banking and Branching Act"), passed by Congress and signed into 
law on September 29, 1994, significantly changed interstate banking rules.  
Pursuant to the Interstate Banking and Branching Act, bank holding companies 
are now able to acquire banks in states other than their home states, 
regardless of applicable state law.

On March 20, 1997, Montana enacted legislation, effective July 1, 1997, which 
authorizes de novo branching within the state by banks chartered under the 
laws of the State of Montana.  In the same legislation, Montana elected to 
"opt out" of full interstate branching available under the Interstate Banking 
and Branching Act, thereby precluding interstate branching in Montana until 
October 1, 2001.


                                        40
<PAGE>

FRB policy provides that a bank holding company is expected to act as a 
source of financial strength to its subsidiary banks and to commit resources 
to support each subsidiary bank in those circumstances where it might not do 
so absent such policy.
   
FIBM is a legal entity separate and distinct from its subsidiaries.  FIBM's 
revenues (on a parent company basis) result in part from dividends of its 
banking subsidiaries.  Under Montana banking law, FIB Montana may not declare 
dividends in any one calendar year in excess of its net earnings of the 
preceding two years without giving notice to the Montana Commissioner of 
Banking and Financial Institutions.  Under Wyoming banking law, FIB Wyoming 
may not, without the approval of the Wyoming Banking Commissioner, declare 
dividends in any one calendar year in excess of its net profits in the 
current year combined with retained net profits of the preceding two years, 
less any required transfers to surplus or a fund for the retirement of any 
preferred stock.

In addition, federal regulatory agencies (e.g., the FDIC, OCC, and FRB) have 
authority to prohibit a bank under their supervision from engaging in 
practices which, in the opinion of the federal regulatory agency, are unsafe, 
unsound, or constitute violations of applicable law.  Each federal regulatory 
agency has established guidelines for the maintenance of appropriate levels 
of capital for a bank under its supervision. Compliance with the standards 
set forth in such guidelines could limit the amount of dividends that FIBM or 
any of its subsidiaries could pay.
    
FDICIA

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"), 
among other things, requires federal banking regulators to take prompt 
corrective action in respect to 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 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 undercapitalized if it is significantly 
below such measure, and critically undercapitalized if it fails to meet any 
critical capital level set forth in regulations.  A depository institution 
may be deemed to be in a capitalization category that is lower than is 
indicated by its actual capital position if it receives an unsatisfactory 
examination rating.  As of December 31, 1996, each of FIBM's banking 
subsidiaries are included in the "well capitalized" capital tier.

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 
restrictions on borrowing from the Federal Reserve System.  In addition, 
undercapitalized depository institutions are subject to growth limitations 
and are required to submit capital restoration plans.  A depository 
institution's holding company must guarantee the capital plan, up to an 
amount equal to the lesser of 5% of the depository institution's total assets 
at the time it becomes undercapitalized or the amount necessary to bring the 
institution into compliance with all capital standards applicable to the 
institution as of the time the institution fails to comply with its 
restoration plan.  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.  If a depository institution fails to submit an 
acceptable plan, it is treated as if it is significantly undercapitalized.  
Significantly undercapitalized depository institutions, or undercapitalized 
institutions that either fail to submit an acceptable capital restoration 
plan or to implement such plan, are subject to a number of requirements and 
restrictions, including but not limited to an order 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 depository institutions are subject to appointment of a 
receiver or conservator.  As of December 31, 1996,  none of FIBM's banking 
subsidiaries are deemed to be undercapitalized by the regulators.

CAPITAL ADEQUACY

The Federal Reserve Board has adopted risk-based capital guidelines for bank 
holding companies.  The minimum guidelines for the ratio of total capital 
("Total Capital") to risk-weighted assets (including certain 
off-balance-sheet items, such as standby letters of credit) is 8%.  At least 
half of the Total Capital is to be composed of common stockholder's equity, 
minority interests in the equity accounts of consolidated subsidiaries, 
qualifying noncumulative perpetual preferred stock, and a limited amount of 
qualifying perpetual preferred stock, less goodwill and other intangibles 
required to be deducted by Federal Reserve regulations ("Tier 1 Capital").  
The remainder may consist of subordinated debt, other preferred stock and a 
limited amount of loan loss reserves.

In addition, the Federal Reserve Board has established minimum leverage ratio 
guidelines for bank holding companies.  These guidelines provide for a 
minimum ratio of Tier 1 Capital to total assets ("Leverage Ratio") of 3% for 
bank holding companies that meet certain specified criteria, including those 
having the highest regulatory rating, well-diversified risk, excellent asset 
quality, high liquidity, good earnings, and generally considered to be a 
strong banking organization.  All other bank holding companies generally are 
required to maintain a Leverage Ratio of at least 3% plus an additional 
cushion of 100 to 200 basis points.  The guidelines also provide that bank 
holding companies experiencing internal growth or making acquisitions will be 
expected to maintain strong capital positions well above the minimum 
supervisory levels without significant reliance on intangible assets.  
Furthermore, the Federal Reserve Board has indicated that it will consider a 
tangible Tier 1 Capital leverage ratio (deducting all intangibles) and other 
indicators of capital strength in evaluating proposals for expansion or new 
activities.

Failure to meet capital guidelines could subject a bank to a variety of 
enforcement remedies, including the termination of deposit insurance by the 
FDIC, and to certain restrictions on its business.

The Company's current consolidated capital ratio substantially exceeds the 
current requirements under these capital guidelines as shown in the following 
table:

                                                      "Adequately

     Risk-based capital ratios:
       Tier 1 capital to risk-weighted assets             4.0%          7.35%

       Total capital to risk-weighted assets              8.0%          9.98%

     Leverage Ratio                                       3.0%          5.26%
   
There have been no material changes in the Company's capital position from
December 31, 1996 to June 30, 1997.
    
SUPPORT OF SUBSIDIARY BANKS

Under Federal Reserve Board policy, FIBM is expected to act as a source of 
financial strength to, and to commit resources to support, its subsidiary 
banks. This support may be required at times when, absent such Federal 
Reserve Board policy, FIBM would not otherwise provide it.  

FIRREA

As a result of the enactment of Section 206 of the Financial Institution 
Reform, Recovery and Enforcement Act ("FIRREA") on August 9, 1989, 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 any commonly controlled FDIC-insured depository institution in danger 
of default.  The phrase "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 INTERSTATE BANKING ACT

The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 took
effect on September 29, 1995.  The Act authorizes interstate banking and
branching, but allows states to "opt out" of interstate branching entirely.  The
Act also provides caps limiting the total percentage of nationwide and statewide
deposits that may be maintained by any banking institution. Prior to passage of
the Act, approximately 45 states, including Montana and Wyoming, already had
laws in effect permitting some form of interstate banking.  The Act is intended
to make the law on interstate banking more uniform and supporters of the
legislation predict that it will produce a more efficient banking system.

The Act is expected to prompt an increase in the number of bank mergers and
acquisitions as institutions expand across state lines, resulting in further
consolidation of the banking industry.  While the legislation is expected to
produce more large banks and growth in the size of banks, which may produce some
competitive advantage, smaller community banks are expected to continue to
exist, although probably in reduced numbers.  The effect of this legislation on
the Company and its business is difficult to assess.  It is likely, however,
that the business environment in which the Company operates will become more
competitive as a result of this legislation. 

MONTANA LEGISLATION

Effective March 20, 1997, the Montana Bank Act  was amended by legislation
clarifying that state chartered banks may, with approval of the Commissioner of
Banking and Financial Institutions, engage in the same activities or business as
national banks, unless expressly prohibited by statute; removing a number of
geographical restrictions on the ability of banks located in this state to
establish and maintain branch banks in this state; eliminating a number of 
restrictions on the consolidation and merger of state chartered banks;
authorizing the sale of branch banks within the state; authorizing the
acquisition of banks located in this state by a bank holding company
headquartered in another state, but subject to a statewide deposit cap of 22%;
and prohibiting banks located in Montana from merging with out-of-state banks
until October 1, 2001.

EMPLOYEES
   
The Company employed approximately 944 full time and 227 part-time employees
as of June 30, 1997.  None of the Company's employees are represented by any
collective bargaining group.  The Company provides a variety of employment
benefits and believes that its relationship with its employees is good.
    
PROPERTIES
   
FIBM's executive offices are located in the same building in Billings, 
Montana, in which the home office of FIB Montana is located.  The Billings 
office of FIB Montana, which subleases space to FIBM as part of a master 
lease, is the anchor tenant in the eighteen story building.  FIB Montana is 
the general partner in 2 partnerships which form a joint venture that owns 
the building.  In addition, FIB Montana leases the buildings in which the 
West Billings, South Missoula and Gardiner branches are located.
    
FIBM's subsidiaries own twenty-four buildings in fourteen communities which are
used, in whole or in part, in their respective banking operations.

and "Notes to Consolidated Financial Statements - Commitments and
Contingencies".

LEGAL PROCEEDINGS

In the normal course of their business, the Company's bank subsidiaries are
named or threatened to be named as defendants in various lawsuits.  With respect
to each of these suits, it is the opinion of management, following consultation
with legal counsel, that the 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 or results of
operations of the Company.

HEALTH AND LIFE INSURANCE.  The Company currently provides all full time
employees (30 or more hours per week) with health and dental insurance coverage,
as well as life insurance (up to two and one half times salary) and disability
insurance benefits at no cost to them.  The contributions to the plan on behalf
of Homer A. Scott, Jr., James R. Scott, Thomas W. Scott, William H. Ruegamer,
William G. Wilson, Terrill R. Moore, Edward Garding, and all executive officers
as a group, were $3,465, $3,216, $3,307, $2,687, $2,687, $3,131, $2,870 and
$14,682, respectively, for the fiscal year ended December 31, 1996.

SURVIVOR INCOME BENEFIT. The Company has entered into Survivor Income Agreements
with certain executive employees to encourage the executives to remain employees
of the Company.  Under the Agreements, designated beneficiaries are entitled to
receive a survivor income benefit if the Company owns a life insurance policy on
the executive's life and if the executive dies before otherwise terminating
employment with the Company.  Pursuant to the Agreements and Addenda thereto, if
the executive voluntarily terminates employment after age sixty (60), the
agreement may convert to a split dollar insurance agreement whereby the
designated beneficiary is entitled to the death proceeds of the life insurance
policy less the cash surrender value of the policy on the day before death.  The
Company has this type of Agreement with William H. Ruegamer, William G. Wilson,
and Edward Garding as well as selected other executive officers.


PROFIT SHARING PLAN.  The Company has a noncontributory qualified profit sharing
plan.  To be eligible to participate, an employee must complete one year of
employment and 1,000 hours or more of service.  Contributions are determined by
the FIBM Board of Directors, but are not to exceed, on an individual basis, the
lesser of 25% of compensation or $30,000.  There is immediate 100% vesting.  The
contributions to the plan on behalf of Homer A. Scott, Jr., James R. Scott,
Thomas W. Scott, William H. Ruegamer, William G. Wilson, Terrill R. Moore,
Edward Garding, and all executive officers as a group, were $4,896, $5,056,
$10,187, $9,396, $5,044, $4,272, $5,227 and $34,126, respectively, for the
fiscal year ended December 31, 1996.  Total contributions to this plan for all
participating employees were $839,360, $685,435, and $620,261 in 1996, 1995 and
1994, respectively.

EMPLOYEE SAVINGS PLAN.  The Company has a contributory qualified employee
savings plan (401(k)).  Eligibility requirements for this plan are the same as
those for the profit sharing plan as discussed in the preceding paragraph. 
Employee participation in the plan is at the option of the employee.  FIBM and
its subsidiaries are required to match $1.25 for every $1.00 of employee
contributions up to 4% of participating employee's compensation.  There is
immediate 100% vesting.  The contributions to the plan on behalf of Homer A.
Scott, Jr., James R. Scott, Thomas W. Scott, William H. Ruegamer, William G.
Wilson, Terrill R. Moore, Edward Garding, and all executive officers as a group,
were $4,696, $5,112, $9,508, $9,500, $4,813, $5,337, $4,334 and $33,492,
respectively, for the year ended December 31, 1996.  Total contributions to this
plan for all participating employees were $814,165 in 1996, $703,128 in 1995 and
$647,565 in 1994.

PRE-TAX SPENDING PLAN.  Full time employees of  the Company are eligible to
participate in the qualified pre-tax spending plan.  The pre-tax spending plan
allows employees to pay for dependent health insurance premiums, unreimbursed
medical and/or dependent child care expenses with before-tax dollars rather than
with after-tax dollars.

RESTRICTED STOCK AWARDS PLAN.  There were no unvested shares issued and
outstanding under the plan at December 31, 1996 or December 31, 1995.

STOCK OPTION AND STOCK APPRECIATION RIGHTS PLAN.  The Company has a
non-qualified Stock Option and Stock Appreciation Rights Plan ("Plan") for key
senior officers of  the Company.  The Plan provides for the granting of stock
options and stock appreciation rights of FIBM's common stock at a value at the
time the options are granted of not less than the existing value of stock at the
date of the grant.  Each option granted under the Plan may be exercised within a
period of ten years from the date of grant.  The Plan provides for the granting
of stock appreciation rights in tandem with stock options.  The Plan allows the
holder to surrender an exercisable stock option in exchange for cash or shares
of common stock in an amount equal to the appraised minority value of covered
shares over the option price of such shares.

OTHER AWARDS OR ARRANGEMENTS.  There were no Long-Term Incentive Plan awards
granted nor any repricing of Stock Options and Stock Appreciation Rights in
1996.  FIBM has no employment contracts and no compensatory plans or
arrangements relating to termination of employment or change in control.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION.  Homer A. Scott,
Jr., Dan S. Scott, James R. Scott and Joel Long serve on the Compensation
Committee.  Therefore, all Committee members except Joel Long were officers or
employees receiving compensation from FIBM for services rendered.  Homer A.
Scott, Jr. and James R. Scott were formerly officers of FIBM.

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION.  The Compensation
Committee establishes the general compensation policies of FIBM and its
Subsidiaries, establishes the compensation plans and specific compensation
levels for executive officers, and administers the Annual Bonus Plan, Restricted
Stock Awards Plan and Stock Option and Stock Appreciation Rights Plan.

As required by recently adopted rules designated to enhance the disclosure of
FIBM's executive compensation policies and practices, the following is the
Compensation Committee's report submitted to the Board of Directors addressing
the compensation of FIBM and its Subsidiaries' executive officers for 1996.

                                          48

COMPENSATION POLICY
    
FIBM's executive compensation policy is designed to establish an appropriate
relationship between executive pay and FIBM's annual performance, its long-term
growth objectives and its ability to attract and retain qualified executive
officers.  The Compensation Committee attempts to achieve these goals by
integrating competitive annual base salaries with (a) bonuses based on corporate
performance and on the achievement of specified performance objectives and (b)
key officer options through the Stock Option Plan.  The Compensation Committee
believes that cash compensation in the form of salary and bonus provides company
executives with short term rewards for success in operations, and that long term
compensation through the award of stock options encourages growth in management
stock ownership which leads to expansion of management's stake in the long term
performance and success of FIBM.

BASE SALARY.  For 1996, the Compensation Committee approved the base salary of
the executive officers.  In determining the base salary of each of the executive
officers, the company relied on three industry surveys of salaries paid to
executive officers of financial institutions with comparable asset size and
similar operating regions to that of FIBM.  The Compensation Committee set the
base salaries of FIBM and its Subsidiaries' executive officers within a
reasonable range of those salaries reflected in the surveys.  In 1996, executive
officers generally received raises in their base salary, with the largest raise
of $6,000 going to the Chief Operating Officer, William H. Ruegamer.  Raises in
base salary reflected an inflationary increase combined with improved corporate
performance and profitability in 1995.

BONUSES.  Annual incentives for the CEO and other executive officers are
intended to reflect FIBM's belief that management's contribution to stockholder
returns (via increasing return on equity and return on assets) comes from
maximizing earnings and the quality of these earnings.  Awards are based on the
attainment of specified performance objectives, and the bonus amount is
determined as a percentage of the recipient's base salary.  For 1996, the CEO
and other executive officers were assigned bonus amounts ranging from 28.1% to
38.8% of the base salaries paid to such persons.  The varying percentages
reflect the Committee's belief that, as an executive officer's duties and
responsibilities in the company increase, the officer will be increasingly
responsible for the performance of FIBM.  Accordingly, a larger portion of the
officer's compensation should be incentive compensation.  Actual bonuses payable
depend on the level of achievement of specified performance objectives.  For
1996, the performance objective necessary to achieve a bonus was attainment of
specified return on stockholders' equity.  During 1996, the specified
performance objectives were attained and exceeded, and therefore the CEO
received the largest bonus of $75,000 (36.4%).  The largest bonus as a
percentage of base salary was paid to the CFO (38.8%).  Increases in bonuses
reflect the continued improved corporate performance in 1996 and completion of
significant acquisitions.

STOCK OPTIONS.  In January 1996, the executive officers as well as certain other
officers of FIBM and its subsidiaries, excluding the CEO and all other Scott
Family members, were each granted options under FIBM's Stock Option Plan to
purchase a specified number of shares of FIBM common stock.  The number of
shares that each officer was granted an option to purchase was in turn based
primarily on the individual's ability to influence the company's long term
growth and profitability as well as the number of options previously granted. 
The Compensation Committee believes that stock option grants afford a desirable
long term compensation method because they closely ally the interests of
management with stockholder value and the grants of stock options are the best
way to link directly the financial interests of management with those of
stockholders.  Options granted are immediately exercisable but must be exercised
within ten years after the date of the grant.

COMPENSATION OF CHIEF EXECUTIVE OFFICER

The Compensation Committee believes that the compensation of the CEO should be
heavily influenced by the performance of FIBM.  Therefore, although there is
necessarily some subjectivity in setting the CEO's salary, a major element of
the compensation package is directly tied to FIBM performance.  In 1996, the
annual base salary of Thomas W. Scott, FIBM's CEO, was raised from $200,000 to
$206,000.  Such increase was determined to be appropriate by the Compensation
Committee based on comparable chief executive salaries, as set forth in surveys
reviewed by FIBM, and improvements in the Company's performance and
profitability in 1995.  The performance targets of FIBM were attained and
exceeded in 1996 and therefore the Compensation Committee awarded a bonus of
$75,000, or 36.4% of annual base compensation.  Thomas W. Scott did not
participate in the decisions of the Compensation Committee with respect to the
salary and bonus paid to him in 1996.

INDEMNIFICATION

Officers and directors of  FIBM are entitled to indemnification under the
Montana Business Corporation Act and pursuant to a Resolution of the Board of
Directors dated January 12, 1987.  A summary of the indemnification provision
follows:

Pursuant to a Resolution of the Board of Directors dated January 12, 1987, and
under the authority of Section 35-1-414 of the Montana Business Corporation Act,
The Company shall indemnify each director and officer of the Company (including
former officers and directors) and each agent of the Company serving as a
director or officer of a subsidiary bank of the Company, serving at the specific
direction or request of the Company (but only to the extent that such director,
officer or agent is not indemnified by the subsidiary bank or by insurance
provided by the Company) against judgments, penalties, fines, settlements and
reasonable expenses actually and reasonably paid by such director, officer or
agent by reason of the fact that he or she is or was a director or officer of
the Company or such subsidiary bank, to the extent provided by and subject to
the limitations of the Montana Business Corporation Act.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provision, the Company has been informed that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is
therefore unenforceable.

PRINCIPAL HOLDERS OF VOTING SECURITIES
   
The directors and executive officers of the Company (11 persons) beneficially 
owned as of July 31, 1997, 1,269,355 shares directly or indirectly, or 63.79%

unexercised.  The Scott Family owns 83.21 percent of the Company Stock, and 
all but two directors of the Company are Scott Family members.  The Scott 
Family has owned a controlling interest in the common stock of FIBM since its 
incorporation in 1971.

  (1)     Shares held in trust with a bank and an individual listed as joint
          trustees are listed under the name of the individual.
  (2)     As a part of overall estate and family succession planning, certain
          Scott Family members have formed partnerships to hold FIBM stock.  The
          Scott Family as a group will continue to control, directly or
          indirectly, the same number of shares of FIBM stock; however, each
          partnership will be a specific shareholder.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

FIBM and its subsidiaries have had, and expect to have in the future, banking
transactions in the ordinary course of business with related parties, including
business with directors, officers, shareholders and their associates, on the
same terms, including interest rates and collateral on loans, as those
prevailing at the same time for comparable transactions with others.  Such
transactions include correspondent banking relationships with affiliated banks,
and data processing servicing for affiliated banks, in addition to other
customary banking services.  To the extent that such transactions consisted of
extensions of credit to Company executive officers and directors and to the
Scott Family, they were made in the ordinary course of business, were made on
substantially the same terms, including interest rates and collateral, as those
prevailing at the time for comparable transactions with other persons, and did
not involve more than a normal risk of collectibility or  present other
unfavorable features.  Loans to FIBM's executive officers, directors and their
related interests represent approximately 6% of the Company's shareholders'
equity as of December 31, 1996.  Loans to executive officers, directors and
related interests of officers and directors of FIBM and its subsidiaries
represent approximately 8% of  the Company's shareholders' equity as of December
31, 1996.

In January 1996, 19,706 shares of the Company's capital stock were sold by the
Scott Family to 287 individual participants in the Company's 401(k) Savings
Plan.  The total cash price was $1,407,403.

In July, 1996, 16,042 shares of the Company's capital stock were sold to 353
individual participants in the Company's 401(k)  Savings Plan.  The total cash
price was $1,262,471.  Further, in July, 1996, 25,070 shares of the Company's
capital stock were sold to certain officers, directors, and employees, including
certain advisory directors and executive officers, for an aggregate cash price
of $1,922,618.

                        INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
First Interstate BancSystem of Montana, Inc.:

We have audited the accompanying consolidated balance sheets of First 
Interstate BancSystem of Montana, Inc. and subsidiaries as of December 31, 
1996 and 1995, and the related consolidated statements of income, 
stockholders' equity, and cash flows for each of the years in the three-year 
period ended December 31, 1996.  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 First 
Interstate BancSystem of Montana, Inc. and subsidiaries at December 31, 1996 
and 1995, and the results of their operations and their cash flows for each 
of the years in the three-year period ended December 31, 1996 in conformity 
with generally accepted accounting principles.

As discussed in note 1, the Company changed its method of accounting for 
investment securities to adopt the provisions of the Financial Accounting 
Standards Board's Statement on Financial Accounting Standards No. 115, 
ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES, effective 
January 1, 1994.

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The Company provides a full range of banking services to individual 
     and corporate customers through its bank and non-bank subsidiaries 
     and their branch offices throughout the states of Montana and 
     Wyoming.  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 
     following is a summary of significant accounting policies utilized by 
     the Company:

     PRINCIPLES OF CONSOLIDATION.  The consolidated financial statements
     include the accounts of First Interstate BancSystem of Montana, Inc.
     (Parent Company) and its operating subsidiaries: First Interstate Bank
     of Commerce in Montana, First Interstate Bank of Commerce in Wyoming,
     First Interstate Bank of Montana, N.A., First Interstate Bank of Wyoming,
     N.A., Mountain Bank, doing business as First Interstate Bank in
     Whitefish, Montana, First Interstate Bank, fsb and Commerce Financial, Inc.
     All material intercompany transactions have been eliminated in
     consolidation.

     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 and the valuation of real estate acquired in connection with
     foreclosures or in satisfaction of loans.  In connection with the
     determination of the allowances for loan losses and real estate owned,
     management obtains independent appraisals for significant properties.
     Management believes that the allowances for losses on loans and real
     estate owned are adequate.  In addition, various regulatory agencies, as
     an integral part of their examination process, periodically review the
     allowances for losses on loans and real estate owned.  While management
     uses available information to recognize losses on loans and real estate
     owned, future additions to the allowances may be necessary based on
     changes in economic conditions which may affect the borrowers' ability to
     pay or regulatory requirements.

     In addition to purchasing and selling Federal funds for their own account,
     the Company purchases and sells Federal funds as an agent.  These and other
     assets held in an agency or fiduciary capacity are not assets of the
     Company and, accordingly, are not included in the accompanying consolidated
     financial statements.

     CASH AND CASH EQUIVALENTS.  For purposes of reporting cash flows, cash and
     cash equivalents include cash on hand, amounts due from banks and federal
     funds sold for one day periods.

     At December 31, 1996 the Company was required to have aggregate reserves in
     the form of cash on hand and deposits with the Federal Reserve Bank of
     approximately $16,060. Also, an additional $23,800 compensating balance was
     maintained with the Federal Reserve Bank to mitigate the payment of service
     charges for check clearing services.
   
     INVESTMENT SECURITIES.  In May 1993, the Financial Accounting Standards
     Board issued Statement of Financial Accounting Standards ("SFAS") No. 115,
     "Accounting for Certain Investments in Debt and Equity Securities".  The
     Company adopted the provisions of the statement as of January 1, 1994.
     There were no cumulative adjustments to income as a result of adopting the
     statement, however, the beginning balance of stockholders' equity was
     increased by $122 (which is net of $66 in deferred income taxes) to reflect
     net unrealized gains on securities classified as available-for-sale
     previously carried at the lower of amortized cost or market.  The Company's
     accounting policy for investment securities is as follows:

          TRADING ACCOUNT ASSETS

          Trading account assets consist of debt and equity securities that are
          bought and held principally for the purpose of selling them in the
          near term and are reported at fair value, with unrealized gains and
          losses included in earnings.  The Company carried no trading account
          assets during 1996 and 1995.

          INVESTMENT SECURITIES HELD-TO-MATURITY AND INVESTMENT SECURITIES
          AVAILABLE-FOR-SALE

          Management determines the appropriate classification of debt 
          securities at the time of purchase.  Debt securities are classified
          as held-to-maturity when the Company has the positive intent and
          ability to hold the securities to maturity.  Held-to-maturity
          securities are stated at amortized cost.
      
          Debt securities not classified as held-to-maturity or trading account
          assets are classified as available-for-sale.  In addition, all equity
          securities not classified as trading are classified as  available-
          for-sale.  Available-for-sale  securities are stated at fair value,
          with the unrealized  gains and losses, net of deferred taxes, reported
          as a separate component of stockholders' equity.

     The amortized cost of debt securities classified as held-to-maturity 
     or available-for-sale is adjusted for amortization of premiums over 
     the estimated average life of the security, accretion of discounts to 
     maturity, or in the case of mortgage-backed securities, over the 
     estimated life of the security.  Such amortization and accretion is 
     included in interest income with interest and dividends.  Realized 
     gains and losses, and declines in value judged to be other-than-temporary,
     are included in investment securities gains (losses).  The cost of
     securities sold is based on the specific identification method.
   
     LOANS.  Loans are reported at the principal amount outstanding.  Interest
     is calculated by using the simple interest method on the daily balance of
     the principal amount outstanding.
   
     Loans on which the accrual of interest has been discontinued are designated
     as nonaccrual loans.  Accrual of interest on loans is discontinued 
     either when reasonable doubt exists as to the full, timely collection of 
     interest or principal or when a 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, interest previously accrued but not 
     collected is reversed against current period interest income.  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.
   
     Renegotiated loans are those loans on which concessions in terms have been 
     granted because of a borrower's financial difficulty.
   
     Significant loan origination fees, net of related costs, are recognized
     over the lives of the related loans as an adjustment of yield.
   
     ALLOWANCE FOR LOAN LOSSES.  The allowance for loan losses is established 
     through a provision for loan losses which is charged to expense.  Loans 
     are charged against the allowance for loan losses when management 
     believes that the collectibility of the principal is unlikely or, with 
     respect to consumer installment loans, according to an established 
     delinquency schedule.  The allowance balance is 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 the collectibility and prior loss experience of loans, 
     leases and commitments to extend credit. 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.

(DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

     The Company may also establish a reserve for losses on specific loans which
     are deemed to be impaired.  Groups of small balance homogeneous basis 
     loans (generally consumer loans) are evaluated for impairment 
     collectively.  A loan is considered impaired when, based upon current 
     information and events, it is probable that the Company will be unable 
     to collect, on a timely basis, all principal and interest according to 
     the contractual terms of the loan's original agreement.  When a specific 
     loan is determined to be impaired, the allowance for loan losses is 
     increased through a charge to expense for the amount of the impairment.  
     The amount of the impairment is measured using cash flows discounted at 
     the loan's effective interest rate, except when it is determined that 
     the sole source of repayment for the loan is the operation or 
     liquidation of the underlying collateral.  In such cases, the current 
     value of the collateral, reduced by anticipated selling costs, will be 
     used to measure impairment instead of discounted cash flows.  The 
     Company's impaired loans are those non-consumer loans which are 
     non-accrual or a troubled debt restructuring.  Interest income is 
     recognized on impaired loans only to the extent that cash payments are 
     received.  The Company's existing policies for evaluating the adequacy 
     of the allowance for loan losses and policies for discontinuing the 
     accrual of interest on loans are used to establish the basis for 
     determining whether a loan is impaired.
   
     GOODWILL AND OTHER INTANGIBLES.  The excess of purchase price over the fair
     value of net assets from acquisitions ("Goodwill") is being amortized 
     using the straight-line method over periods of primarily 15 to 25 years. 
     The Company assesses the recoverability of Goodwill by determining whether
     the unamortized balance related to an acquisition can be recovered through
     undiscounted future cash flows over the remaining amortization period.
   
     Core deposit intangibles represent the intangible value of depositor 
     relationships resulting from deposit liabilities assumed in acquisitions 
     and are amortized using an accelerated method based on an estimated 
     runoff of the related deposits, not exceeding 10 years.  Purchased 
     mortgage servicing rights ("MSR") represent the value of purchased 
     rights to service mortgage loans.  The MSR are amortized in proportion 
     to and over the period of estimated net servicing income not expected to 
     exceed 12 years.  MSR are evaluated for impairment based on the MSR 
     current fair value.
   
     PREMISES AND EQUIPMENT.  Buildings, furniture and equipment are stated at 
     cost less accumulated depreciation.  Depreciation is provided over 
     estimated useful lives of 5 to 50 years for buildings and improvements 
     and 3 to 15 years for furniture and equipment using straight-line 
     methods.  Leasehold improvements are amortized using straight-line 
     methods over the shorter of the estimated useful lives of the 
     improvements or the terms of the related leases.  Consolidated 
     depreciation expense was $4,182 in 1996, $3,541 in 1995 and $3,318 in 
     1994.
   
     LONG-LIVED ASSETS.  The Company adopted the provisions of SFAS No. 121, 
     "Accounting for the Impairment of Long-Lived Assets for Long-Lived 
     Assets to Be Disposed Of," on January 1, 1996. The statement requires 
     long-lived assets and certain identifiable intangibles (e.g. premises, 
     Goodwill, core deposit intangibles) be reviewed for impairment whenever 
     events or changes in circumstances indicate the carrying amount of an 
     asset may not be recoverable.  An asset is deemed impaired if the sum of 
     the expected future cash flows is less than the carrying amount of the 
     asset.  The amount of the impairment loss is based on the assets' fair 
     value, which may be estimated by discounting the expected future cash 
     flows.  The adoption of SFAS No. 121 did not have a material impact on 
     the Company's consolidated financial position or consolidated results of 
     operations.
   
     OTHER REAL ESTATE OWNED.  Real estate acquired in satisfaction of loans is 
     carried at the lower of the recorded investment in the property at the 
     date of foreclosure or its current fair value less selling cost ("Net 
     Realizable Value").  The value of the underlying loan is written down to 
     the fair market value of the real estate acquired by a charge to the 
     allowance for loan losses, if necessary, at the date of foreclosure.  A 
     provision to the real estate owned valuation allowance is charged 
     against other real estate expense for any current or subsequent 
     write-downs to Net Realizable Value.  Operating expenses of such 
     properties, net of related income, and gains on sales are included in 
     other real estate expenses.
   
     SELF-INSURANCE.  The Company is self-insured with respect to employee 
     medical claims up to specified limits per claim.  The Company has an 
     accrual of approximately $560 for estimated unsettled and incurred 
     but not reported claims.

     INCOME FROM FIDUCIARY ACTIVITIES.  Consistent with industry practice, 
     income for trust services is recognized on the basis of cash received.  
     However, use of this method in lieu of accrual basis accounting does not 
     materially affect reported earnings.
   
     INCOME TAXES.  The Parent Company and its subsidiaries have elected to be 
     included in a consolidated Federal income tax return.  For state income 
     tax purposes, the combined taxable income of the Parent Company and its 
     subsidiaries is apportioned between the states in which operations take 
     place. Federal and state income taxes attributable to the subsidiaries, 
     computed on a separate return basis, are paid to or received from the 
     Parent Company.
   
     Deferred tax assets and liabilities are reflected at currently enacted 
     income tax rates applicable to the period in which the deferred tax 
     assets or liabilities are expected to be realized or settled.  As 
     changes in tax laws or rates are enacted, deferred tax assets and 
     liabilities are adjusted through the provision for income taxes.
   
     PER SHARE DATA.  Earnings per common share is calculated by dividing 
     net income less preferred stock dividends by the weighted average number 
     of common shares and common share equivalents outstanding during the 
     period. Book value per common share is calulated by dividing total 
     stockholders' equity less preferred stock by the number of common 
     shares outstanding at the end of the year.
   
     STOCK-BASED COMPENSATION.  The Company adopted SFAS No. 123, "Accounting 
     for Stock-Based Compensation," as of January 1, 1996.  SFAS No. 123 
     encourages all entities to adopt a new method of accounting to measure 
     compensation cost of all employee stock compensation plans based on the 
     estimated fair value of the award at the date it is granted.  Companies 
     are, however, allowed to continue to measure compensation cost for those 
     stock-based employee compensation plans using the intrinsic value-based 
     method of accounting, which generally results in compensation expense 
     only when the exercise price is less than the fair value of the 
     underlying stock at the date of grant.  Companies that elect to remain 
     with the intrinsic value method are required to disclose in a footnote 
     to the financial statements pro forma net income and earnings per share, 
     as if the fair value method of SFAS No. 123 had been adopted.  The 
     Company has elected to continue accounting for stock-based employee 
     compensation plans in accordance with Accounting Principles Board 
     No. 25 (see note 12).
   
     RECLASSIFICATIONS.  Certain reclassifications have been made to the 1995
     and 1994 amounts to conform to the 1996 presentation.
   
(2)  REGULATORY MATTERS
   
     The Federal Reserve Board (FRB) and the Federal Deposit Insurance 
     Corporation (FDIC) have 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.  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 intangible assets are 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, 1996, the Company's consolidated risk-based capital (core 
     plus supplementary) and core capital ratios, calculated in accordance 
     with the guidelines, were 10.0% and 7.4%, 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 Company's consolidated leverage ratio at
     December 31, 1996 was 5.3%.
   
     The Federal Deposit Insurance Corporation Improvement Act ("FDICIA"), 
     which was enacted on December 19, 1992, 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 3% leverage).  At December 31, 1996, the Company's and bank 
     subsidiaries' capital ratios meet or 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%.

     --------------------------------------------------------------------------
     --------------------------------------------------------------------------
        (1)  Includes loans to agricultural customers secured by real estate of
             $52,689 and $43,826 at December 31, 1996 and 1995, respectively.
        (2)  Includes loans secured by commercial real estate properties of
             $198,570 and  $145,380 at December 31, 1996 and 1995, respectively.
        (3)  Includes loans secured by second mortgages on real estate of
             $74,607 and $53,046 at December 31, 1996 and 1995, respectively.

     At December 31, 1996, the Company had no concentrations of loans which 
     exceeded 10% of total loans other than the categories disclosed above.  
     The Company has no loans or loan commitments to highly leveraged 
     companies.

     Nonaccrual loans amounted to $6,822 and $3,632 at December 31, 1996 and 
     1995, respectively.  If interest on nonaccrual loans had been accrued, 
     such income would have approximated $405 and $318, respectively.  Loans 
     contractually past due ninety days or more aggregating $6,432 on 
     December 31, 1996 and $1,711 on December 31, 1995 were on accrual 
     status.  Such loans are deemed adequately secured and in the process of 
     collection.

     Included in the nonaccrual loans at December 31, 1996 and 1995 are 
     $5,122 and $3,231, respectively, of loans which are considered impaired. 
     Of this amount, an impairment allowance of $436 and $407, respectively, 
     is included in the Company's allowance for loan losses.  The average 
     recorded investment in impaired loans for the years ended December 31, 
     1996 and 1995 was approximately $3,870 and $3,080, respectively.  If 
     interest on impaired loans had been accrued, the amount of interest 
     income on impaired loans during 1996 and 1995 would have been 
     approximately $357 and $283, respectively.

     Also included in total loans at December 31, 1996 and 1995 are loans 
     with a carrying value of $1,763 and $1,755, respectively, the terms of 
     which have been modified in troubled debt restructurings.  There were no 
     nonaccrual loans included in restructured debt at December 31, 1996.  
     Restructured debt includes nonaccrual loans of $15 at December 31, 1995. 
     During the years then ended, the recognized interest income on 
     restructured loans approximated $158 and $161, respectively. At December 
     31, 1996, there were no commitments to lend additional funds to 
     borrowers whose existing loans have been restructured or are classified 
     as nonaccrual.

     Most of the Company's business activity is with customers within the 
     state of Montana and Wyoming.  Loans where the customers or related 
     collateral are out of the Company's trade area are not significant and 
     management's anticipated credit losses arising from these transactions 
     compare favorably with the Company's credit loss experience on its loan 
     portfolio as a whole.

     Certain executive officers and directors of the Company and certain 
     corporations and individuals related to such persons, incurred 
     indebtedness in the form of loans, as customers, of approximately 
     $11,474 at December 31, 1996 and $12,802 at December 31, 1995 (including 
     outstanding loans of new executive officers and directors in 1996).  
     During 1996, new loans and advances on existing loans of $2,700 were 
     funded and repayments totaled $4,028.  These loans were made on 
     substantially the same terms, including interest rates and collateral, 
     as those prevailing at the time for comparable risk of collectibility.

(8)  CASH SURRENDER VALUE OF LIFE INSURANCE

     The Company maintains key-executive life insurance policies
     on certain principal shareholders.  Under the key-executive
     insurance, the Company receives the cash surrender value if the
     policy is terminated, or receives all benefits payable upon the
     death of the insured.  The aggregate face amount of key-executive
     insurance policies was $7,000 at December 31, 1996.  Cash
     surrender values are recorded net of outstanding policy loans,
     since the Company has no current plans for repayment.  Outstanding
     policy loans at December 31, 1996 and 1995 are $2,540 and $1,875,
     respectively.  The net cash surrender value of key-executive
     insurance policies included in other assets is $278 and $792 at
     December 31, 1996 and 1995, respectively.

     During 1994, the Company provided insurance contracts for
     certain key officers.  The net cash surrender value of these
     contracts is $1,365 and $1,218 at December 31, 1996 and 1995,
     respectively, and is included in other assets.  Upon retirement,
     the officers have the option of entering into a split-dollar
     contract with the Company providing insurance coverage for the
     difference between the Company's cash surrender value and the face
     amount of the policy.

(9)  DEPOSITS

     Deposits are summarized as follows:

     December 31,                                1996         1995

     In assessing the realizability of deferred tax assets,
     management considers whether it is more likely than not that some
     portion or all of the deferred tax assets will not be realized.
     The ultimate realization of deferred tax assets is dependent upon
     the existence of, or generation of, taxable income in the periods
     which those temporary differences are deductible.  Management
     considers the scheduled reversal of deferred tax liabilities,
     taxes paid in carryback years, projected future taxable income,
     and tax planning strategies in making this assessment.  Based upon
     the level of historical taxable income and projections for future
     taxable income over the periods which the deferred tax assets are
     deductible, at December 31, 1996 management continues to believe
     it is more likely than not that the Company will realize the
     benefits of these deductible differences.

     The Company has a revolving term loan with its primary lender
     in the amount of $42,000 at December 31, 1996.  The available
     borrowing amount is reduced by $2,000 on a semi-annual basis
     commencing in June 1997.  The revolving facility requires an
     annual commitment fee of 0.15% on the unadvanced amount.  The
     Company may elect at various dates either prime or a Eurodollar 
     rate plus 1.75%.  The term note payable is secured by
     100% of the outstanding capital stock of the Company's bank
     subsidiaries.

     The notes payable to Federal Home Loan Bank of Seattle (FHLB)
     are secured by FHLB stock, unencumbered residential real estate
     mortgages and certain mortgage-backed securities.

     The Company has Federal funds lines of credit with third
     parties amounting to $50,000, subject to funds availability.  The
     Company also has been approved for participation in the Federal
     Home Loan Bank Cash management Advance Program for borrowings up
     to approximately $39,500.

(12) EMPLOYEE BENEFIT PLANS

     PROFIT SHARING PLAN.  The Company has a noncontributory
     profit sharing plan.  To be eligible for the profit sharing plan,
     an employee must complete one year of employment and 1,000 hours
     or more of service.  Quarterly contributions are determined by the
     Company's Board of Directors, but are not to exceed, on an
     individual basis, the lesser of 25% of compensation or $30.
     Contributions to this plan were $839, $685 and $620 in 1996, 1995
     and 1994, respectively.

     SAVINGS PLAN.  In addition, the Company has a contributory
     employee savings plan.  Eligibility requirements for this plan are
     the same as those for the profit sharing plan as discussed in the
     preceding paragraph.  Employee participation in the plan is at the
     option of the employee.  The Company contributes $1.25 for each
     $1.00 of employee contributions up to 4% of the participating
     employee's compensation.  The recorded expense related to this
     plan was $814 in 1996, $703 in 1995 and $648 in 1994.

     STOCK OPTION PLAN.  The Company has a Nonqualified Stock
     Option and Stock Appreciation Rights Plan for senior officers of
     the Company.  All options and stock appreciation rights ("SAR's")
     granted have an exercise price of book value of the Company prior
     to 1993 and appraised value thereafter.  Each option granted under
     the Plan can be immediately exercised up to ten years from the
     date of grant.  SAR's are granted and exercised in tandem with
     options.  The stock issued in conjunction with the exercise of
     options is subject to a shareholder agreement (see note 15).  The
     consolidated expense related to this plan was $72 in 1996, $170 in
     1995 and $387 in 1994.

     Information with respect to the Company's stock options and
     SAR's are as follows:

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

     The Company has elected to continue to measure compensation costs as 
     prescribed by APB Opinion No. 25 and, accordingly, does not recognize 
     compensation expense on the options granted where the exercise price is
     equal to appraisal value at the date of grant.  SFAS No. 123 requires the
     Company to disclose pro forma information reflecting net income and
     earnings per share had the Company elected to record compensation expense
     based on the fair value method described in SFAS No. 123.  The fair value
     of the options was estimated at the grant date using a Black-Scholes option
     pricing model.  Option valuation models require the input of highly
     subjective assumptions.  Because the Company's common stock and stock
     options have characteristics significantly different from listed securities
     and traded options, and because changes in the subjective input assumptions
     can materially affect the fair value estimate, in management's opinion, the
     existing models do not necessarily provide a reliable single measure of the
     fair value of its stock options.

     The following weighted-average assumptions were used in the valuation 
     model: risk-free interest rates of 5.65% and 7.78% in 1996 and 1995;
     dividend yield of 2.50% and 2.67% in 1996 and 1995; and expected life of
     options of 10 years in both 1996 and 1995.

     Pro forma disclosures, listed below, include options granted in 1996 and
     1995 and are not likely to be representative of the pro forma disclosures
     for future years.  The estimated fair value of the options is expensed in
     the year granted as all options are vested upon grant.

(13) COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Company is involved in various claims
     and litigation.  In the opinion of management, following consultation with
     legal counsel, the ultimate liability or disposition thereof will not have
     a material adverse effect on the consolidated financial condition or
     results of operations.

     The Parent Company and the Billings office of First Interstate Bank of 
     Commerce in Montana ("FIB Montana") are the anchor tenants in a building 
     owned by a joint venture partnership in which FIB Montana is one of the two
     partners, and has a 50% partnership interest.  The investment in the 
     partnership is accounted for using the equity method.  Indebtedness of the
     partnership in the amount of $10,827 at December 31, 1996 is recourse to 
     the partners. Total rents paid to the partnership were $814 in 1996, $711 
     in 1995 and $690 in 1994.

     The Company also leases certain premises and equipment from third parties
     under operating leases.  Total rental expense to third parties was $1,019
     in 1996, $1,425 in 1995 and $1,267 in 1994.

     In September 1983, the Company entered into a franchise agreement 
     ("Franchise Agreement") with First Interstate Bancorp ("First 
     Interstate"), a Los Angeles based bank holding company which was 
     acquired by Wells Fargo and Company April 1, 1996.  Under the Franchise 
     Agreement, the Company was First Interstate's exclusive licensee in the 
     states of Montana and Wyoming.  On May 24, 1996, the Company entered 
     into a trademark license agreement granting the Company and its 
     subsidiaries an exclusive, nontransferable license to use the "First 
     Interstate" name and logo in the states of Montana, Wyoming, North 
     Dakota, South Dakota and Nebraska.  By mutual agreement of the parties, 
     the franchise agreement between the Company and Wells Fargo and Company 
     was terminated.

(14) 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.  These financial instruments include commitments to extend
     credit and standby letters of credit.  These instruments involve, to
     varying degrees, elements of credit and interest rate risk in excess of
     amounts recorded in the consolidated balance sheet.

     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 less than two 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.

     Commitments to extend credit are agreements to lend to a customer as 
     long as there is no violation of any condition established in the 
     commitment 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 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.
     
     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.  At December 31, 1996, stand-by letters of 
     credit in the amount of $19,884, were outstanding.  Commitments to 
     extend credit to existing and new borrowers approximated $284,259 at 
     December 31, 1996, which includes $32,760 on unused credit card lines.

(15) CAPITAL STOCK

     On September 26, 1996 ("Issuance Date"), the Company issued 20,000 
     shares of no par noncumulative perpetual preferred stock ("Preferred 
     Stock") at a price of $1,000.  The holders of Preferred Stock are 
     entitled to receive in any fiscal year, when and if declared by the 
     Company's Board of Directors, dividends in cash at the rate of $85.30 
     per share, up to the seventh anniversary of the Issuance Date.  From and 
     after the seventh anniversary of the Issuance Date, the holders of 
     Preferred Stock shall be entitled to receive in any fiscal year, when 
     and if declared by the Company's Board of Directors, dividends in cash 
     at a variable rate equal to 250 basis points over the high yield of the 
     30-day, 10-year or 30-year U.S. Treasury Bills.  The Preferred Stock is 
     not redeemable prior to the seventh anniversary of the Issuance Date.  
     The Company may, at its option, redeem all or any part of the Preferred 
     Stock at any time on or after the seventh anniversary of the Issuance 
     Date, subject to the approval of the FRB, at a price of $1.00 per share, 
     plus accrued but unpaid dividends to the date fixed for redemption.
     
     At December 31, 1996 nearly all shares of common stock held by 
     shareholders are subject to shareholder's agreements (Agreements).  
     Under the Agreements, the Company has a right of first refusal to 
     repurchase shares from the shareholder at minority interest appraised 
     value in the event of a proposed sale of shares to a third party, death, 
     disability or termination of employment.  Additional shares purchased by 
     officers, directors and employees after 1993 are also subject to 
     repurchase at the Company's discretion.

(17) DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

     Statement of Financial Accounting Standards No. 107, DISCLOSURES ABOUT 
     FAIR VALUE OF FINANCIAL INSTRUMENTS (Statement 107), requires the 
     Company to disclose the estimated fair values of its financial 
     instruments.  Most of the Company's assets and liabilities are 
     considered financial instruments.  Many of the Company's financial 
     instruments lack an available trading market, and it is the practice and 
     intent of the Company to hold its financial instruments to maturity. As 
     a result, significant assumptions and present value calculations were 
     used in determining estimated fair values.

     For financial instruments bearing a variable interest rate, it is 
     presumed that recorded book values are reasonable estimates of fair 
     value.  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.
     
          INTEREST-BEARING DEPOSITS IN BANK.  Due to the short-term nature of 
          the instrument, the carrying value of the interest-bearing deposit 
          in bank 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.
     
          LOANS.  Fair values are estimated for portfolios of loans with 
          similar financial characteristics.  Loans are segregated by type 
          such as commercial, real estate, and consumer.  Each loan category 
          is further segmented into fixed and adjustable rate interest terms 
          and by performing and nonperforming categories. 


                                       F-22
<PAGE>

          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.
          
          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.
          
          DEPOSITS, FEDERAL FUNDS PURCHASED AND SECURITIES SOLD UNDER 
          REPURCHASE AGREEMENTS.  The fair value of demand deposits, savings 
          accounts, federal funds purchased 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 with similar remaining maturities.
          
          OTHER BORROWED FUNDS AND LONG-TERM DEBT.  The term note payable and 
          revolving term loan bear interest at a floating market rate and, as 
          such, the carrying amounts are deemed to reflect fair value.  The 
          carrying value of the interest bearing demand notes to the United 
          States Treasury is deemed an approximation of fair value due to the 
          frequent repayment and repricing at market rates.  Due to the 
          recent issuance date of the subordinated notes and relative 
          stability of interest rates in the intervening period, book value 
          is estimated to approximate 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 information is not readily available to 
          support estimates of fees which can be expected to be realized on 
          these instruments.
          
          Loan fees for the year ended December 31, 1996 and 1995, including 
          fees charged for commitments to extend credit and standby letters 
          of credit, were approximately $4,981 and $4,070, respectively, of 
          which a significant portion related to real estate refinancing.
          
          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 entire holdings of a particular instrument.  Because no 
          market exists for a significant portion of the 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.  For 
          example, the Company has a trust department and data processing 
          division that contribute net operating income annually.  Neither 
          department is considered a financial instrument, and their value 
          has not been incorporated into the fair value estimates.  Other 
          significant assets that are not considered financial instruments 
          include the mortgage subsidiary, deferred tax assets, and 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.

     The unaudited pro forma information above has been prepared for comparative

     that would have occurred if the operations had been combined during the
     periods presented nor is it intended to be a projection of future results.

(19) ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED

     In 1996, the FASB issued SFAS No. 125, "Accounting for Transfers 
     and Servicing of Financial Assets and Extinguishments of Liabilities," 
     which provides guidance on accounting for transfers and servicing of 
     financial assets, recognition and measurement of servicing assets and 
     liabilities, financial assets subject to prepayment, secured borrowings 
     and collateral, and extinguishment of liabilities.
     
     SFAS No. 125 generally requires the Company to recognize as separate 
     assets the rights to service mortgage loans for others, whether 
     the servicing rights are acquired through purchases or loan 
     originations.  Servicing rights are initially recorded at fair value 
     based upon the present value of estimated future cash flows.  
     Subsequently, the servicing rights are assessed for impairment, with 
     impairment losses recognized in the statement of income in the period 
     the impairment occurs.  For purposes of performing the impairment 
     evaluation, the related portfolio must be stratified on the basis of 
     certain risk characteristics including loan type and note rate.  SFAS 
     No. 125 also specifies that financial assets subject to prepayment, 
     including loans that can be contractually prepaid or otherwise settled 
     in such a way that the holder would not recover substantially all of its 
     recorded investment, be measured like debt securities available-for-sale 
     or trading securities under SFAS No. 115.  The provisions of SFAS No. 
     125 apply prospectively to transactions occurring after December 31, 
     1996.  Management expects adoption will not have a material effect on 
     the consolidated financial position or results of operations of the 
     Company.

     At December 31, 1996, the Company serviced loans for others with a 
     principal balance outstanding of approximately $140,000.

            Notes to Unaudited Consolidated Financial Statements 
                            (Dollars in thousands)



(1)  BASIS OF PRESENTATION

     In the opinion of management, the accompanying unaudited consolidated 
     financial statements contain all adjustments (all of which are of a normal
     recurring nature) necessary to present fairly the consolidated financial 
     position at June 30, 1997 and December 31, 1996, and the results of 
     consolidated operations and cash flows for each of the six month periods
     ended June 30, 1997 and 1996 in conformity with generally accepted 
     accounting principles.  The balance sheet information at December 31, 1996
     is derived from audited consolidated financial statements, however, certain
     reclassifications have been made to conform to the June 30, 1997 
     presentation.

     In June 1996, the Financial Accounting Standards Board ("FASB") issued
     Statement of Financial Accounting Standards ("SFAS") No. 125, "Accounting
     for Transfers and Servicing of Financial Assets and Extinguishments of 
     Liabilities." SFAS No. 125 requires the Company to recognize as separate
     assets the rights to service mortgage loans for others, whether the 
     servicing rights are acquired through purchases or loan originations.
     Servicing rights are initially recorded at fair value based upon the 
     present value of estimated future cash flows. Subsequently, the servicing
     rights are assessed for impairment, with impairment losses recognized in 
     the statement of income in the period the impairment occurs. For purposes
     of performing the impairment evaluation, the related portfolio must be 
     stratified on the basis of certain risk characteristics including loan 
     type and note rate. SFAS No. 125 also specifies that financial assets 
     subject to prepayment, including loans that can be contractually prepaid or
     otherwise settled in such a way that the holder would not recover 
     substantially all of its recorded investment, be measured like debt 
     securities available-for-sale or trading securities under SFAS No. 115. The
     Company adopted the provisions of SFAS No. 125 as of January 1, 1997. The 
     adoption did not have a material effect on the financial position or 
     results of operations of the Company.


(2)  CASH AND CASH EQUIVALENTS

     For purposes of reporting cash flows, cash and cash equivalents include  
     cash on hand, amounts due from banks and Federal funds sold for one-day- 
     periods.


(3)  COMPUTATION OF EARNING PER SHARE

     Earnings per common share are computed by dividing net income less 
     preferred stock dividends by the weighted average number of shares of 
     common stock outstanding during the period presented.  Stock options 
     outstanding are considered common stock equivalents, and are included in
     computations of  weighted average shares outstanding.

(4)  CASH DIVIDENDS

     On July 21, 1997, the Company paid a cash dividend on second quarter 
     earnings of $1.00 per share to stockholders of record on that date.  It has
     been the Company's practice to pay quarterly dividends based upon earnings.
     The July 1997 dividend represents 30% of the Company's net income for the 
     quarter ended June 30, 1997.

(7)  ACQUISITIONS

     On February 5, 1997, First Interstate Bank of Montana, N.A. purchased the
     assets of Mountain Financial, a loan production office located in Eureka,
     Montana.  The total cash purchase price of the assets acquired aggregated
     $1,726, of which $166 was for premises and equipment and the remaining
     $1,560 was for loans acquired.
          
     During June 1997, the Company finalized its allocation of purchase price
     related to the 1996 acquisitions of First Interstate Bank of Montana, N.A.,
     First Interstate Bank of Wyoming, N.A. and Mountain Bank of Whitefish. 
     Changes in preliminary estimates of the fair value of loans, other assets
     and other liabilities resulted in a $3.5 million decrease in goodwill.

(8)  COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Company is named or threatened to be
     named as  defendant in various lawsuits, some of which involve claims for
     substantial amounts of actual and/or punitive damages.  With respect to
     each of these suits it is the opinion of management, following consultation
     with legal counsel, the 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 or
     the results of operations.  

     During 1985, the Company entered into a partnership agreement with two
     outside parties for the purpose of purchasing certain land and building
     with an aggregate cost of approximately $20,000.  The Company is a tenant
     in the building and owns a 50% undivided interest in the property. 
     Indebtedness of the partnership in the amount of $10,617 at June 30, 1997
     is guaranteed by each of the partners.

     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.  These financial instruments include commitments to extend
     credit and standby letters of credit.  These instruments involve, in
     varying degrees, elements of credit and interest rate risk in excess of
     amounts recorded in the consolidated balance sheet.

     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 two
     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.

     Commitments to extend credit are agreements to lend to a customer as long
     as there is no violation of any condition established in the commitment
     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.

     In February 1997, the FASB issued SFAS No. 128, "Earnings per Share," which
     simplifies the standards for computing earnings per share ("EPS") by
     replacing the presentation of primary EPS with a presentation of basic EPS
     on the face of the income statement for all entities with complex capital
     structures.  SFAS No. 128 also requires a reconciliation of the numerator
     and the denominator of the basic EPS computation to the numerator and
     denominator of the diluted EPS computation.

     Basic EPS excludes dilution and is computed by dividing income available to
     common stockholders by the weighted average number of common shares
     outstanding for the period.  Diluted EPS reflects the potential dilution
     that could occur if securities or other contracts to issue common stock
     were exercised or resulted in the issuance of common stock that then shared
     in the earnings of the entity.

     This statement is effective for financial statements issued for periods
     ending after December 15, 1997.  Earlier application is not permitted. 
     Once effective, this statement requires restatement of all prior period EPS
     data.  Pro forma basic and diluted net income per share as determined under
     this statement will not differ from amounts currently reported by the
     Company.

     In February 1997, the FASB issued SFAS No. 129, "Disclosure of Information
     about Capital Structure," which lists required disclosures about capital
     structure that had been included in a number of previously existing
     separate statements and opinions.  SFAS No. 129 is effective for financial
     statements for periods ending after December 15, 1997.

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
     Income," which establishes standards for reporting and display of
     comprehensive income and its components (revenues, expenses, gains, and
     losses) in a full set of general-purpose financial statements.  This
     statement requires that all items required to be recognized under
     accounting standards as components of comprehensive income be reported in a
     financial statement that is displayed with the same prominence as other
     financial statements.  This statement does not require a specific format
     for that financial statement but requires that an entity display an amount
     representing comprehensive income for the period in that financial
     statement.

     This statement requires that an entity (a) classify items of other
     comprehensive income by  their nature in a financial statement and (b)
     display the accumulated balance of other comprehensive income separately
     from retained earnings and additional paid-in-capital in the equity section
     of a statement of financial position.

     This statement is effective for fiscal years beginning after December 15,
     1997.  Reclassification of financial statements for earlier periods
     provided for comparative purposes is required.

                             SHAREHOLDER'S AGREEMENT

     THIS AGREEMENT is made this ____ day of _____, 19__, by and between
________________________________ herein referred to as "Shareholder", and FIRST
INTERSTATE BANCSYSTEM OF MONTANA, INC., a Montana corporation, 401 North 31st
Street, Billings, Montana 59101, herein referred to as the "Corporation".

                              W I T N E S S E T H :

     A.  Shareholder owns shares of capital stock of the Corporation, which
stock, together with any additional stock here-after acquired by Shareholder, is
herein referred to as the "Shares".

     B.  Except with respect to the Corporation stock addressed by a separate
agreement, the Corporation desires to restrict the issuance and holding of its
corporate stock to officers, directors and employees of the Corporation or any
of its subsidiaries, or to fiduciaries for the benefit of any such persons.
Such persons' status as director, officer or employee shall be herein referred
to as the "Shareholders' Relationship with the Corporation".

     C.  The Corporation and Shareholder desire to obligate each other to sell
and purchase shares under specified circumstances.

     NOW, THEREFORE, in consideration of the above facts and the Shareholder's
and the Corporation's mutual promises herein, the Shareholder and the
Corporation agree as follows:

     1.  RESTRICTION ON TRANSFER OR PLEDGE OF SHARES.  Except as otherwise
provided in this Agreement or as agreed upon in writing by the Shareholder and
the Corporation, Shareholder shall not transfer or permit to be transferred,
whether voluntarily, involuntarily or by operation of law, resulting from death
or otherwise, any or all of the Shares now owned or hereafter acquired by
Shareholder, and any attempted transfer in violation of this Agreement shall be
void.  Shareholder shall not encumber or use any Shares as security for a loan,
except upon the written consent of the Corporation.

     2.  PURCHASE OPTION UPON BONA FIDE SALE.  If a Shareholder intends to sell
any Shares to any person other than the Corporation, Shareholder shall give
ninety (90) days' written notice to the Corporation of the intention to sell
Shares.  The notice, in addition to stating the fact of the intention to sell
Shares, shall state (i) the number of Shares to be sold, (ii) the name and
address of the proposed purchaser, (iii) the amount of the consideration and the
other terms of the sale.  At the request of the Corporation, Shareholder shall
demonstrate to the reasonable satisfaction of the Corporation that the intended
sale is bona fide.  Within ninety (90) days of the Corporation's receipt of the
notice of intention to sell Shares, the Corporation may exercise an option to
purchase all but not less than all of the Shares proposed to be sold.

     3.  PURCHASE OPTION UPON DEATH.  Upon Shareholder's death, the Corporation,
within ninety (90) days of the appointment of a personal representative for the
deceased Shareholder's estate, for which written notice must be given by said
personal representative within ten (10) days of appointment, may exercise an


                                        1

                                    EXHIBIT A
                                    ---------
<PAGE>

option to purchase all but not less than all of the deceased Shareholder's
Shares from the personal representative of his or her estate.

     4.  PURCHASE OPTION UPON INVOLUNTARY TRANSFER.   If other than by reason of
Shareholder's death, Shares are transferred by operation of law to any person
other than the Corporation (such as but not limited to a shareholder's trustee
in bankruptcy, a purchaser at any creditor's or court sale or the guardian or
conservator of an incompetent shareholder), Shareholder shall immediately give
written notice to the Corporation of such transfer.  The Corporation, within
ninety (90) days of the Corporation's receipt of actual notice of the transfer,
may exercise an option to purchase all but not less than all of the Shares so
transferred.

     5.  PURCHASE OPTION UPON TERMINATION OF RELATIONSHIP WITH THE CORPORATION.
Upon the termination of Shareholder's Relationship with the Corporation, such
termination being for any reason whatsoever, including but not limited to the
voluntary resignation of Shareholder, the Corporation, within ninety (90) days
of the date of such termination, may exercise an option to purchase all but not
less than all of the Shares owned by the terminated Shareholder at the time of
such termination.

     6.  PURCHASE OPTION UPON DISABILITY.  If Shareholder shall become totally
disabled, the Corporation, within ninety (90) days of the date of such total
disability, may exercise an option to purchase all but not less than all of the
Shares owned by the disabled Shareholder at the time of the commencement of his
or her total disability.  A shareholder shall be deemed totally disabled within
the meaning of this paragraph 6 if as a result of sickness, accident or injury,
he or she become wholly and continuously unable to perform his or her duties for
a period of six consecutive months, and his or her disability shall be deemed to
have commenced at the end of said six-month period.

     7.  GENERAL CORPORATE PURCHASE OPTION.  Upon determination by the
Corporation's Compensation Committee of the Board of Directors that the number
of Shares held by Shareholder is excessive in view of the Corporation's policy
that the level of a shareholder's stock ownership should reflect certain
factors, including but not limited to (a) the relative contribution of
Shareholder to the economic performance of the Corporation, (b) the effort being
put forth by Shareholder, and (c) the level of responsibility of Shareholder,
the Corporation may exercise an option to purchase a portion of Shareholder's
Shares sufficient to decrease the number of Shares owned by the Shareholder to
an amount that the Compensation Committee, in its sole discretion, believes is
appropriate.  The Corporation shall not exercise said option in anticipation of
a sale of the Corporation or a majority of the Corporation's stock and the
Corporation agrees to exercise said option in a nondiscriminatory fashion.  The
number of Shares that the Corporation can purchase from Shareholder is limited
to the stock obtained by the Shareholder after January 1, 1994.

     8.  EXERCISE OF OPTION.  The Corporation shall exercise the Option granted
in paragraphs 2, 3, 4, 5, or 6 by delivering written notice of its exercise of
the option, within the times provided in said paragraphs, to the Shareholder in
the case of a paragraph 2 option, to the personal representative of
Shareholder's estate in the case of a paragraph 3 option, to the transferee in
the case of a paragraph 4 option, to the terminated Shareholder in the case of a
paragraph 5


                                        2
<PAGE>

option, and to the disabled shareholder in the case of a paragraph 6 option.
The Corporation shall exercise the option granted in paragraph 7 by delivering
written notice of its exercise of the option, specifying the number of Shares to
be purchased, to the Shareholder.

     9.  EFFECT OF NON-EXERCISE OF OPTIONS.  If the purchase options are
forfeited or not exercised in compliance with the terms of this Agreement then
the Shares to which the option applied shall be unrestricted and no longer
subject to the terms of this Agreement.

     10.  THE PURCHASE PRICE.  The purchase price of Shares shall be their
Appraised Value on the Closing Date determined using the most recent quarterly
appraisal available to the Corporation, less any dividends paid to Shareholder
since said appraisal.  The Corporation's Shares shall be appraised as of the
last day of each calendar quarter by an unaffiliated firm qualified to make such
an appraisal.  The expense of determining the Appraised Value shall be borne by
the Corporation.

     The Corporation may, at its option, withhold any amount that the
Shareholder owes the Corporation or its subsidiaries from the amount of the
Purchase Price payable to Shareholder and apply said amount to such
indebtedness.

     11.  PAYMENT OF THE PURCHASE PRICE.

     11.1 PAYMENT TERMS.  The purchase price for Shares shall be paid either in
cash at closing or, at Shareholder's election, in installments as follows:

             (a)  25% of the purchase price at the closing.

             (b)  The balance of the purchase price in three (3) equal
                  consecutive annual amortized installments, including interest
                  at an annual rate equal to the four-year Certificate of
                  Deposit rate being paid by First Interstate Bank of Commerce
                  on the date of closing, the first installment to be paid one
                  year after the closing, and the remaining installments each
                  year thereafter.

     11.2 PROMISSORY NOTE ON DEFERRED PORTION.  The deferred portion of the
purchase price, if any, shall be evidenced by the promissory note of the
Corporation made payable to the order of the Shareholder.  The Corporation note
shall be in substantially the form of that set forth in Exhibit A.

the Corporation of its exercise of the option to purchase the Shareholder's
Shares.

     12.2 DOCUMENTS.  At the closing of the sale and purchase, the Shareholder
and the Corporation shall execute and immediately deliver to each other the
various documents which shall be required to carry out their undertakings

clear of all taxes, debts, claims, judgments, liens or encumbrances whatsoever.

     13.  LEGEND ON CERTIFICATES.  All Shares now or hereafter owned by
Shareholder shall be subject to the provisions of this Agreement and
Shareholder, and his or her transferee or successor agrees that the certificates
representing same shall bear the following legend reciting the existence of the
Agreement:

     The sale, transfer or encumbrance of this certificate is subject to an
     agreement to restrict transfer or acquisition of the shares.  A copy of the

in the lines of business of the Company.  The staff of Alex Sheshunoff & Co.
Investment Banking are qualified appraisers and exhibit such through our
extensive experience performing over 1,500 appraisals of banks and bank holding
companies over the past 5 years.

In preparing the valuation report, we reviewed information regarding the 
Company's financial performance and condition for the three years ending 
December 31, 1996 and the six months ending June 30, 1997.  We received 
from the Company projected income, asset growth, book value, and dividends 
for the five fiscal years ending December 31, 2001.  We did not verify the
accuracy of such information and assumed it to be accurate in all

material respects.  We did not independently value the assets and liabilities 
of the Company and have not been furnished with appraisals.  We also reviewed 
other publicly available information regarding the market for bank and bank 
holding company common stock and economic conditions in the Company's market 
area.  We believe such publicly available information to be accurate; 
however, we cannot guarantee the accuracy of such information.

We valued the shares at their "fair market value" as of the valuation date. 
Fair market value is defined as the price at which the shares would change hands
between a willing buyer and a willing seller when the former is not under any
compulsion to buy and the latter is not under any compulsion to sell.  Both
parties are assumed to be able and willing to trade and are well informed about
all relevant factors impacting the value of the shares and their market.  

We considered the Company as a going-concern under its current business 
strategy and did not value the shares based upon a liquidation or other 
restructuring of the Company.  We believe that the most useful valuation 
approach under the fair market valuation method is to derive the value of 
shares based upon the price of comparable transactions of institutions in the 
same lines of business as the Company.  However, because the market for the 
Company's common stock is relatively illiquid, we have presented the value of 
such shares utilizing the net present valuation method as well.  We also 
considered the appropriate adjustments to the shares as a result of the lack 
of marketability of such shares and the terms of the Company's 401(k) and 
Profit Sharing Plan (the "Plan").

In arriving at our opinion of the fair market value of the shares, we considered
the financial performance and condition of the Company and its subsidiary
including future earnings and dividend paying capacity, the economic outlook of
the trade area and the banking industry in general, previous sales of the
Company's stock, the size of the shares being valued, and the market price of
selected comparable banking institutions. 

It is our opinion that as of June 30, 1997, the fair market value of the 
minority block of the outstanding common stock was $95.00 per share.  Our 
valuation of the shares shall not be construed and is not intended to be a 
recommendation with respect to the purchase or sale of the common stock of 
the Company.  Our valuation is solely our opinion of the fair market value of 
the shares and may be materially different at any date other than the 
valuation date indicated herein.  The application of the valuation 
methodologies utilized in arriving at our opinion is discussed in the
accompanying valuation report, which should be read in its entirety to fully
understand our conclusion.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

Officers and directors of FIBM are entitled to indemnification under the 
Montana Business Corporation Act and pursuant to a Resolution of the Board of 
Directors dated January 12, 1987.  A summary of the indemnification 
provisions follows:

Pursuant to a Resolution of the Board of Directors dated January 12, 1987 and 
under the authority of Section 35-1-414 of the Montana Business Corporation 
Act, FIBM shall indemnify each director and officer of FIBM (including former 
officers and directors) and each agent of FIBM serving as a director or 
officer of a subsidiary bank of FIBM, serving at the specific direction or 
request of FIBM (but only to the extent that such director, officer or agent 
is not indemnified by the subsidiary bank or by insurance provided by FIBM) 
against judgments, penalties, fines, settlements and reasonable expenses 
actually and reasonably paid by such director, officer or agent by reason of 
the fact that he or she is or was a director or officer of FIBM or such 
subsidiary bank, to the extent provided by and subject to the limitations of 
the Montana Business Corporation Act (which indemnification and limitations 
as of the date of the adoption of this bylaw and set forth in Section 35-1-414 
of the Montana Code Annotated).

Insofar as indemnification for liabilities arising under the Securities Act 
of 1933 may be permitted to directors, officers and controlling persons of 
FIBM pursuant to the foregoing provisions, or otherwise, FIBM 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 FIBM of expenses incurred 
or paid by a director, officer or controlling person of FIBM 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, FIBM will, unless in the opinion of its counsel the matter 
has been settled by controlling precedent, submit to a court or 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.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

1.  FIBM has issued bonuses of common stock to certain key officers of the
Company in January, 1997, and in January of each of the past three years.  
The dates of issuance, total number of shares issued, per share value of the 
stock, and total dollar amount of stock issued as officer bonuses are as 
follows:

                      Number     Per Share      Total Dollar
  Date              of Shares      Value           Amount   
  ----              ---------    ----------     ------------

  January, 1997       1,009       $80.21          $80,932

  January, 1994       1,146       $47.25          $54,149

Exemption from registration of the stock was claimed because no offer or sale 
of the stock was made, as defined in Section 2(3) of the Securities Act 
of 1933. The stock was issued by FIBM without any election or decision of the 
officers to participate, and the officers had no option to receive cash or 
other consideration in lieu of stock.

2.  FIBM has issued stock options and stock appreciation rights to key 
officers of the Company in January, 1997, and in January of each of the past 
three years, pursuant to its Stock Option and Stock Appreciation Rights Plan. 
 See "MANAGEMENT - EXECUTIVE AND DIRECTOR COMPENSATION - Stock Option and 
Stock Appreciation Rights Plan."  Exemption from registration of the stock 
options and stock appreciation rights was claimed because no offer or sale of

of the Securities Act of 1933.  The stock options and appreciation rights

1933.  The stock options and stock appreciation rights were issued privately 
by FIBM only to key officers of  the Company.  The grantees in each case were 
people generally familiar with the business, management and financial 
information of the Company.  Stock options and stock appreciation rights were 
issued to 35 key officers in 1997, 35 key officers in 1996, 34 key officers 
in 1995 and 30 key officers in 1994.

3.  On January 28, 1994, outstanding stock options were exercised for the
