                                    PART I

                              ITEM 1.  BUSINESS

THE COMPANY

     First Interstate BancSystem, Inc. ("FIBS" and collectively with its 
subsidiaries, the "Company") is a bank holding company.  FIBS was 
incorporated in 1971 and is headquartered in Billings, Montana.  In October 
1997, FIBS changed its name from "First Interstate BancSystem of Montana, 
Inc." to "First Interstate BancSystem, Inc."

     FIBS operates two wholly-owned bank subsidiaries (collectively, the 
"Banks" and individually a "Bank") with 32 banking offices in 23 Montana and 
Wyoming communities and FIB Capital Trust ("FIB Capital"), a wholly-owned 
non-bank subsidiary.  At December 31, 1997, the Company had assets of $2.2 
billion, deposits of $1.8 billion and total stockholders' equity of $146 
million, making it the largest independent banking organization headquartered 
in Montana or Wyoming.

     The Company, through the Banks, delivers a comprehensive range of 
consumer and commercial banking services to individual and business 
customers. These services include personal and business checking and savings 
accounts, time deposits, individual retirement accounts, cash management, 
trust services and commercial, consumer, real estate, agricultural and other 
loans. Additionally, the Company operates a substantial data processing 
division that performs data processing services for the Banks and 34 
non-affiliated financial institutions in Montana, Wyoming and Idaho. The data 
processing division also supports over 630 ATM locations in 13 states, 
principally Montana, Wyoming, Idaho, Colorado and North Dakota. 

     The Company is the licensee under a trademark license agreement between 
Wells Fargo & Company and the Company granting it an exclusive, 
nontransferable license to use the "First Interstate" name and logo in the 
states of Montana and Wyoming with additional rights in selected other 
states. 

     In October 1997, the Company effected a four-for-one stock split of its 
existing common stock.  Unless otherwise indicated, information regarding 
common stock of the Company contained herein has been retroactively restated 
to give effect to the stock split.

COMMUNITY BANKING PHILOSOPHY

     The Company's banking offices are located in communities with 
populations generally ranging from approximately 5,000 to 70,000 people, but 
serve market areas with greater populations because of the limited number of 
financial institutions within a reasonable distance from the communities in 
which such offices are located. The Company believes that these communities 
provide a stable core deposit and funding base, as well as economic 
diversification across a number of industries, including agriculture, energy, 
mining, timber processing, tourism, government services, education and 
medical services. 

     The banking industry is presently undergoing change with respect to 
regulatory matters, consolidation, changing consumer needs and economic and 
market conditions. The Company believes that it can best address this 
changing environment through its "Strategic Vision." Through the Strategic 
Vision, the Company emphasizes providing its customers full service 
commercial and consumer banking at a local level using a personalized service 
approach, while serving and strengthening the communities in which the Banks 
are located through community service activities. 

     The Company grants significant autonomy and flexibility to the banking 
offices in delivering and pricing products at the local level in response to 
market considerations and customer needs. This flexibility and autonomy 
enables the banking offices to remain competitive and enhances the 
relationships between the banking offices and the customers they serve. The 
Company also emphasizes accountability, however, by establishing performance 
and incentive standards for the Banks which are tied to net income at the 
individual branch level. The Company believes that this combination of 
autonomy and accountability allows the banking offices to provide a high 
level of personalized service to customers while remaining attentive to 
financial performance.

                                     -2-


GROWTH STRATEGY

     The Company's growth strategy includes growing internally and expanding 
into new and complementary markets when appropriate opportunities arise. The 
Company believes it has in place an infrastructure that will allow for growth 
and yield economies of scale on a going forward basis. The Company has 
received regulatory approval to open three new banking offices in Montana and 
Wyoming and will continue to expand its presence in the Montana and Wyoming 
markets.

INTERNAL GROWTH

     The Company's internal growth strategy is to attract and retain 
customers by providing personalized "high touch" service, increasing its 
offering of products and services and cross-selling existing products and 
services. The Company believes its ability to offer a complete package of 
consumer and commercial banking products and services enhances the Company's 
image as a "one-stop" banking organization. The Company creates awareness of 
its products and services through various marketing and promotional efforts, 
including involvement in community activities. 

EXTERNAL GROWTH

     The Company has grown in recent years by selectively acquiring banks in 
additional markets in Montana and Wyoming.  Since September 1996, the Company 
has acquired eight banking offices.  The Company considers acquisitions which 
will enhance its existing position within a market, expand its presence into 
complementary markets, or add capabilities or personnel that will enhance the 
Company as a whole.  The Company has a selective acquisition strategy in that 
it principally considers those institutions with strong financial and 
managerial resources already in place. 

THE BANKS

     First Interstate Bank in Montana ("FIB Montana"), a Montana chartered 
bank organized in 1916, has 21 banking offices in 15 Montana communities, 
including Billings, Bozeman, Colstrip, Cut Bank, Eureka, Evergreen, Gardiner, 
Great Falls, Hamilton, Hardin, Kalispell, Livingston, Miles City, Missoula 
and Whitefish. These communities are home to a variety of industries, 
including agriculture, mining, energy, timber processing, tourism, government 
services, education and medical services, with a significant number of small 
to medium sized businesses. As of December 31, 1997, FIB Montana held assets 
and deposits totaling $1.5 billion and $1.2 billion, respectively.  FIB 
Montana is the largest independent bank headquartered in Montana. The Bank's 
main office is located in Billings, Montana.  During June 1997, the Company 
merged together three of its Montana bank subsidiaries, First Interstate Bank 
of Commerce, First Interstate Bank of Montana, N.A. and Mountain Bank of 
Whitefish, and changed the resultant bank name to "First Interstate Bank" in 
Montana.  In December 1997, First Interstate Bank, fsb, the Company's savings 
bank subsidiary, was merged into FIB Montana and the Company's thrift charter 
was terminated.

     First Interstate Bank in Wyoming ("FIB Wyoming"), a Wyoming chartered 
bank organized in 1893, has 11 banking offices in eight Wyoming communities, 
including Buffalo, Casper, Gillette, Greybull, Lander, Laramie, Riverton and 
Sheridan. These communities are home to a variety of industries, including 
energy, agriculture, mining, tourism, government services, education and 
medical services with a significant number of small to medium sized 
businesses.  As of December 31, 1997, FIB Wyoming held assets and deposits 
totaling $750 million and $642 million, respectively. The Bank's main office 
is located in Sheridan, Wyoming.  During 1997, the Company merged together 
its two Wyoming bank subsidiaries, First Interstate Bank of Commerce in 
Wyoming and First Interstate Bank of Wyoming, N.A., and changed the resultant 
bank name to "First Interstate Bank" in Wyoming.

                                     -3-


ADMINISTRATION OF THE BANKS

     Each of the Banks and their respective banking offices operate with a 
significant level of autonomy and are responsible for day-to-day operations, 
the pricing of loans and deposits, lending decisions and community relations. 
 FIBS also emphasizes accountability, however, by establishing performance 
and incentive standards for the Banks which are tied to net income at the 
individual branch level. FIBS provides general oversight and centralized 
services for the Banks to enable them to serve their markets more 
effectively. These services include data processing, credit administration, 
auditing, asset/liability management, investment analysis, human resources 
management, marketing and planning coordination. FIBS continues to emphasize 
corporate administration of functions which assist the Banks and their 
branches in more effectively focusing on their respective markets and 
customers. Key among those functions are the following:

DATA PROCESSING

     FIBS provides most of its and the Banks' data processing requirements. 
These services, including general ledger, investment securities management 
and loan and deposit processing, are performed through the use of computer 
hardware which the Company owns and maintains and software which it licenses. 
The Company's data processing division also operates an extensive ATM network 
for the benefit of the Banks' customers. 

CREDIT ADMINISTRATION

     FIBS has established comprehensive credit policies which guide the 
Banks' lending activities. These policies establish system-wide standards and 
assist Bank management in the lending process. On the local level, the Banks 
are granted significant autonomy and flexibility with respect to credit 
pricing issues and lending decisions. 

FINANCIAL AND ACCOUNTING

     FIBS provides all accounting services for the Banks, including general 
ledger administration, internal and external reporting, asset/liability 
management and investment portfolio analysis. In addition, the Company has 
established policies regarding capital expenditures, asset/liability 
management and capital management. 

SUPPORT SERVICES

     FIBS provides the Banks with legal and compliance services, internal 
auditing services, marketing services, planning coordination, human resources 
and employee benefits administration, and various other services. The Company 
believes the centralization of these services yields economies of scale, 
increases the efficiency of the Banks and allows management of the banking 
offices to focus on serving their market areas and customers. 

LENDING ACTIVITIES

     The Banks offer short and long-term commercial, consumer, real estate, 
agricultural and other loans to individuals and small to medium sized 
businesses in each of their market areas. The lending activities of the Banks 
and their branches are guided by the Company's comprehensive lending and 
credit guidelines. The Company believes that it is important to keep the 
credit decision at the local branch level in order to enhance the speed and 
efficiency with which the customer is served. While each loan must meet 
minimum underwriting standards established in the Company's lending policy, 
lending officers are granted certain levels of autonomy in approving and 
pricing loans. The Company-established credit policies are intended to 
maximize the quality and mix of loans, while also assuring that the Banks and 
their branches are responsive to competitive issues and community needs in 
each market area. The credit policies establish specific lending authorities 
to Bank officers, reflecting their individual experience and level of 
authority, type of loan and collateral, and thresholds at which loan requests 
must also be approved at a Bank committee level and/or by FIBS.

     FIBS oversees the lending activities of the Banks and is responsible for 
monitoring general lending activities. Areas of oversight include the types 
of loans, the mix of variable and fixed rate loans, delinquencies, 
non-performing assets, classified loans and other credit information to 
evaluate the risk within each Bank's loan portfolio and to recommend general 
reserve percentages and specific reserve allocations.

                                      -4-


     The Company's loan portfolio is diversified across commercial, consumer, 
real estate, agricultural and other loans, with a mix of fixed and variable 
rate loans. Individual branches are granted autonomy with respect to product 
pricing, which is significantly influenced by the markets in which the 
particular banking offices are located.

     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 or which are secured by real 
property whose value tends to be more easily ascertainable, commercial 
business loans involve different risks and are typically 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. 

COMMERCIAL LOANS

     The Banks provide a mix of variable and fixed rate commercial loans. The 
loans are typically made to small to medium sized manufacturing, wholesale, 
retail and service businesses for working capital needs and business 
expansions. As of December 31, 1997, 35.8% of the Company's loan portfolio 
was composed of commercial loans. Commercial loans generally include lines of 
credit and loans with maturities of five years or less. The loans are 
generally made with the business operations as the primary source of 
repayment, but also include collateralization by inventory, accounts 
receivable, equipment, real estate and/or personal guarantees. 

CONSUMER LOANS

     The Banks' consumer loans include personal automobile loans, home 
improvement loans and equity lines of credit. The consumer loans are 
generally secured by automobiles, boats and other types of personal property 
and are made on an installment basis. The equity lines of credit are 
generally floating rate, reviewed annually and secured by residential real 
estate. Over two-thirds of the Company's consumer loans are indirect dealer 
paper which is created when the Company advances money to dealers of consumer 
products who in turn lend such money to consumers purchasing automobiles, 
boats and other consumer goods. As of December 31, 1997, 34.4% of the 
Company's loan portfolio was composed of consumer and personal loans. 

REAL ESTATE LOANS

     The Banks provide interim and permanent financing for both single-family 
and multi-unit properties and medium term loans for commercial and industrial 
buildings. The Banks originate variable and fixed rate real estate mortgages, 
generally in accordance with the guidelines of the Federal National Mortgage 
Association and the Federal Home Loan Mortgage Corporation. Loans originated 
in accordance with these guidelines are sold in the secondary market. Real 
estate loans are typically secured by first liens on the financed property. 
As of December 31, 1997, 18.3% of the Company's loan portfolio was composed 
of real estate loans, many of which are fixed rate loans, with maturities 
generally less than 15 years. 

AGRICULTURAL LOANS

     Agricultural loans generally consist of short and medium-term loans and 
lines of credit and are made to the large base of farm and ranch operations 
in the Company's market areas.  The Banks make agricultural loans in many of 
the communities they serve, which are generally used for crops, livestock, 
buildings and equipment, and general operating purposes.  Agricultural loans 
are generally secured by assets such as livestock or equipment and are repaid 
from the operations of the farm or ranch. As of December 31, 1997, 11.1% of 
the Company's loan portfolio was composed of agricultural loans.  
Agricultural loans generally have maturities of five years or less, with 
operating lines lasting for one production season.

                                     -5-


FUNDING SOURCES

     Each of the Banks offers usual and customary depository products 
provided by commercial and retail banks, including personal and business 
checking accounts, savings accounts and time deposits (including IRAs). 
Deposits at the Banks are insured by the Federal Deposit Insurance 
Corporation ("FDIC") up to statutory limits.  While the Company develops and 
offers a wide array of deposit products, local branch management is given 
relative autonomy in pricing the depository products offered to customers, in 
an attempt to best compete in each Bank's particular market. As of December 
31, 1997, approximately 38.0%, 23.9% and 38.1% of the Company's deposits 
consisted of demand, savings and time deposits, respectively.

     The Company also has a significant number of repurchase agreements 
primarily with commercial depositors. Under the repurchase agreements, the 
Company sells, but does not transfer on its books or otherwise, investment 
securities held by the Company to a customer under an agreement to repurchase 
the investment security at a specified time or on demand. 

OTHER OPERATIONS

     In addition to the services mentioned above, the Company offer safe 
deposit boxes, night depository services and wire transfers, among other 
things.  The Company also operates a substantial data processing division 
that performs data processing services for the Banks and 34 non-affiliated 
financial institutions in Montana, Wyoming and Idaho.  The data processing 
division also provides support for over 630 ATM locations in 12 states, 
principally in Montana, Wyoming, Idaho, Colorado and North Dakota.

     The Company, through the Banks, offers a full range of fee-based trust 
services to its individual, non-profit and corporate clients, including 
corporate pension plans, individual retirements plans and 401(k) plans.

COMPETITION

     The banking and financial services business in both Montana and Wyoming 
is highly competitive.  The Banks compete for loans, deposits and customers 
for financial services with other commercial banks, savings and loan 
associations, securities and brokerage companies, mortgage companies, 
insurance companies, finance companies, money market funds, credit unions and 
other nonbank financial service providers.  The Company competes in its 
markets on the basis of its Strategic Vision philosophy, timely and 
responsive customer service and general market presence. Several of the 
Company's competitors are much larger in total assets and capitalization, 
have greater access to capital markets and offer a broader array of financial 
services than the Banks. Moreover, the Banking and Branching Act has 
increased competition in the Banks' markets, particularly from larger, 
multi-state banks.  See "Regulation and Supervision."  The Company competes 
with several large, multi-state banks as well as numerous smaller community 
banks. Principal competitors include Norwest Corporation, U.S. Bancorp and 
Community First Bankshares, Inc.  With respect to core deposits, the Company 
believes it ranks second in market share to all other competitors in each of 
Montana and Wyoming. See "Risk Factors-Competition." 

EMPLOYEES

     The Company employed approximately 971 full-time and 226 part-time 
employees as of December 31, 1997. None of the Company's employees are 
covered by a collective bargaining agreement. The Company considers its 
employee relations to be good. 

REGULATION AND SUPERVISION

     Bank holding companies and commercial banks are subject to extensive 
regulation under both federal and state law.  Set forth below is a summary 
description of certain laws which relate to the regulation of FIBS and the 
Banks.  The description does not purport to be complete and is qualified in 
its entirety by reference to the applicable laws and regulations. 

FIRST INTERSTATE BANCSYSTEM, INC.

     As a bank holding company, FIBS is subject to regulation under the Bank 
Holding Company Act of 1956, as amended (the "BHCA"), and to supervision and 
regulation by the Federal Reserve.

                                     -6-


The Federal Reserve may require that FIBS terminate an activity or terminate 
control of or liquidate or divest certain Banks if the Federal Reserve 
believes such activity or control constitutes a significant risk to the 
financial safety, soundness or stability of any of the Banks or is in 
violation of the BHCA. The Federal Reserve also has the authority to regulate 
provisions of certain bank holding company debt, including authority to 
impose interest ceilings and reserve requirements on such debt. Under certain 
circumstances, FIBS must file written notice and obtain approval from the 
Federal Reserve prior to purchasing or redeeming its equity securities.  
Further, FIBS is required by the Federal Reserve to maintain certain levels 
of capital. See "Capital Standards" herein. 

     FIBS is required to obtain the prior approval of the Federal Reserve for 
the acquisition of 5% or more of the outstanding shares of any class of 
voting securities or substantially all of the assets of any bank or bank 
holding company. Prior approval of the Federal Reserve is also required for 
the merger or consolidation of FIBS and another bank holding company. 

     FIBS is prohibited by the BHCA, except in certain statutorily prescribed 
instances, from acquiring direct or indirect ownership or control of 5% or 
more of the outstanding voting shares of any company that is not a bank or 
bank holding company and from engaging directly or indirectly in activities 
other than those of banking, managing or controlling banks or furnishing 
services to its subsidiaries. However, FIBS, subject to the prior approval of 
the Federal Reserve, may engage in, or acquire shares of companies engaged 
in, activities that are deemed by the Federal Reserve to be so closely 
related to banking or managing or controlling banks as to be a proper 
incident thereto. In making any such determination, the Federal Reserve may 
consider, among other things, whether the performance of such activities by 
FIBS or an affiliate can reasonably be expected to produce benefits to the 
public, such as greater convenience, increased competition or gains in 
efficiency, that outweigh possible adverse effects, such as undue 
concentration of resources, decreased or unfair competition, conflicts of 
interest or unsound banking practices. The Federal Reserve is also empowered 
to differentiate between activities commenced de novo and activities 
commenced by acquisition, in whole or in part, of a going concern. On 
September 30, 1996, the Economic Growth and Regulatory Paperwork Reduction 
Act of 1996 (the "1996 Budget Act") eliminated the requirement that bank 
holding companies seek Federal Reserve approval before engaging de novo in 
permissible nonbanking activities listed in Regulation Y, which governs bank 
holding companies, if the holding company and its lead depository institution 
are well-managed and Well-Capitalized (as defined herein) and certain other 
criteria specified in the statute are met. For purposes of determining the 
capital levels at which a bank holding company is considered 
"Well-Capitalized" under the 1996 Budget Act and Regulation Y, the Federal 
Reserve adopted, as a rule, risk-based capital ratios (on a consolidated 
basis) that are the same as the levels set for determining that a state 
member bank is Well Capitalized under the provisions established under the 
prompt corrective action provisions of federal law.  See "Prompt Corrective 
Action and Other Enforcement Mechanisms" herein. 

     Under Federal Reserve regulations, a bank holding company is required to 
serve as a source of financial and managerial strength to its subsidiary 
banks and may not conduct its operations in an unsafe or unsound manner. In 
addition, it is the Federal Reserve's policy that in serving as a source of 
strength to its subsidiary banks, a bank holding company should stand ready 
to use available resources to provide adequate capital funds to its 
subsidiary banks during periods of financial stress or adversity and should 
maintain the financial flexibility and capital-raising capacity to obtain 
additional resources for assisting its subsidiary banks. A bank holding 
company's failure to meet its obligations to serve as a source of strength to 
its subsidiary banks will generally be considered by the Federal Reserve to 
be an unsafe and unsound banking practice or a violation of the Federal 
Reserve's regulations or both. 

THE BANKS

     FIB Montana is subject to the supervision of and regular examination by 
the Federal Reserve and the State of Montana. FIB Wyoming is subject to the 
supervision of and regular examination by the FDIC and the State of Wyoming.  
If any of the foregoing regulatory agencies determine that the financial 
condition, capital resources, asset quality, earning prospects, management, 
liquidity or other aspects of a Bank's operations are unsatisfactory or that 
the Bank or its management is violating or has violated any law or 
regulation, various remedies are available to such agencies. These remedies 
include the power to enjoin "unsafe or unsound" practices, to require 
affirmative action to correct any conditions resulting from any violation or 
practice, to issue an administrative order that can be judicially enforced, 
to direct an increase in capital, to restrict the growth of the Bank, to 
assess civil monetary penalties, to remove officers and directors and 
ultimately to terminate a Bank's deposit insurance, which would result in a 
revocation of the Bank's charter. None of the Banks has been the subject of 
any such actions by their respective regulatory agencies.

                                     -7-


     The FDIC insures the deposits of the Banks in the manner and to the 
extent provided by law. For this protection, the Banks pay a semiannual 
statutory assessment. See "Premiums for Deposit Insurance" herein. 

     Various requirements and restrictions under the laws of the states of 
Montana and Wyoming and the United States affect the operations of the Banks. 
State and federal statutes and regulations relate to many aspects of the 
Banks' operations, including levels of capital, reserves against deposits, 
interest rates payable on deposits, loans, investments, mergers and 
acquisitions, borrowings, dividends, locations of banking offices and capital 
requirements. 

RESTRICTIONS ON TRANSFERS OF FUNDS TO FIBS AND THE BANKS

     FIBS is a legal entity separate and distinct from the Banks. Statutory 
and regulatory limitations exist with respect to the amount of dividends 
which may be paid to FIBS by the Banks. 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. As a Federal Reserve 
member bank, FIB Montana may not, without the consent of the Federal Reserve, 
declare dividends in a calendar year which, when aggregated with prior 
dividends in that calendar year, exceed the calendar year net profits of FIB 
Montana together with retained earnings for the prior two calendar years. 
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, there are 
restrictions under the Company's debt instruments which may limit the amount 
of the Banks' dividends in certain circumstances. 
     
     The bank regulatory agencies also have authority to prohibit the Banks 
from engaging in activities that, in their respective opinions, constitute 
unsafe or unsound practices in conducting their business. It is possible, 
depending upon the financial condition of the Bank in question and other 
factors, that the bank regulatory agencies could assert that the payment of 
dividends or other payments might, under some circumstances, be an unsafe or 
unsound practice. Further, the bank regulatory agencies have established 
guidelines with respect to the maintenance of appropriate levels of capital 
by banks or bank holding companies under their jurisdiction. Compliance with 
the standards set forth in such guidelines and the restrictions that are or 
may be imposed under the prompt corrective action provisions of federal law 
could limit the amount of dividends which the Banks or FIBS may pay.  See 
"Prompt Corrective Action and Other Enforcement Mechanisms" and "Capital 
Standards" herein for a discussion of these additional restrictions on 
capital distributions. 
     
     A large portion of FIBS's revenues, including funds available for the 
payment of interest on the indebtedness of the Company, dividends and 
operating expenses are, and will continue to be, dividends paid by the Banks. 
     
     The Banks are also subject to certain restrictions imposed by federal 
law on any extensions of credit to, or the issuance of a guarantee or letter 
of credit on behalf of, FIBS or any affiliate of FIBS, the purchase of or 
investments in stock or other securities thereof, the taking of such 
securities as collateral for loans and the purchase of assets of FIBS or the 
Banks. Such restrictions prevent FIBS and the Banks from borrowing from the 
Banks unless the loans are secured by marketable obligations or other 
acceptable collateral of designated amounts. Further, such secured loans and 
investments by the Banks to or in FIBS are limited to 10% of the respective 
Bank's capital stock and surplus (as defined by federal regulations) and such 
secured loans and investments are limited, in the aggregate, to 20% of the 
respective Bank's capital stock and surplus (as defined by federal 
regulations). Additional restrictions on transactions may be imposed on the 
Banks by state or federal regulations including under the prompt corrective 
action provisions of federal law.  See "Prompt Corrective Action and Other 
Enforcement Mechanisms" herein. 

COMMON LIABILITY

     Under federal law, 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 in connection with the default of a commonly controlled 
FDIC-insured depository institution or any assistance provided by the FDIC to 
a commonly controlled FDIC-insured institution in danger of default. These 
provisions can have the effect of making one Bank responsible for 
FDIC-insured losses at another Bank.

EFFECT OF GOVERNMENT POLICIES AND LEGISLATION

     Banking is a business that depends on interest rate differentials. In 
general, the difference between the interest rate paid by the Banks on their 
deposits and borrowings and the interest rate received by the Banks on loans 
extended to their customers and on investment securities comprises a major 
portion of the Banks' earnings. These rates are highly sensitive to many 
factors that are beyond the control of the Banks. Accordingly, the earnings 
and potential growth of the Banks are subject to the influence of domestic 
and foreign economic conditions, including inflation, recession and 
unemployment.

     The commercial banking business is not only affected by general economic 
conditions but is also influenced by the monetary and fiscal policies of the 
federal government and the policies of regulatory agencies, particularly the 
Federal Reserve. The Federal Reserve implements national monetary policies 
(with objectives such as curbing inflation and combating recession) by its 
open-market operations in United States government securities, by adjusting 
the required level of reserves for financial institutions subject to the 
Federal Reserve's reserve requirements and by varying the discount rates 
applicable to borrowings by depository institutions. The actions of the 
Federal Reserve in these areas influence the growth of bank loans, 
investments and deposits and also affect interest rates charged on loans and 
paid on deposits. The nature and impact of any future changes in monetary 
policies cannot be predicted. 

     From time to time, legislation is enacted which has the effect of 
increasing the cost of doing business, limiting or expanding permissible 
activities or affecting the competitive balance between banks and other 
financial service providers. Proposals to change the laws and regulations 
governing the operations and taxation of banks, bank holding companies and 
other financial service providers are frequently made in Congress, in the 
Montana and Wyoming legislatures and before various bank regulatory and other 
professional agencies. The likelihood of any major legislative changes and 
the impact such changes might have on FIBS or the Banks are impossible to 
predict. 

CAPITAL STANDARDS

     The Federal Reserve and the FDIC have adopted risk-based minimum capital 
guidelines intended to provide a measure of capital that reflects the degree 
of risk associated with a banking organization's operations for transactions 
reported on the balance sheet as both assets and transactions, such as 
letters of credit and recourse arrangements. Under these guidelines, nominal 
dollar amounts of assets and credit equivalent amounts of off-balance sheet 
items are multiplied by one of several risk adjustment percentages, which 
range from 0% for assets with low credit risk, such as certain U.S. Treasury 
securities, to 100% for assets with high credit risk, such as commercial 
loans. 

     A banking organization's risk-based capital ratios are obtained by 
dividing its qualifying capital by its total risk-adjusted assets. The 
regulators measure risk-adjusted assets, which include off-balance sheet 
items, against both total qualifying capital (the sum of Tier 1 capital and 
limited amounts of Tier 2 capital (both as defined herein)) and Tier 1 
capital. The Company's "Tier 1 capital" consists of: (i) common stockholders' 
equity and retained earnings; (ii) noncumulative perpetual preferred stock, 
if any; (iii) mandatorily redeemable preferred securities of subsidiary 
trust, if any; and (iv) minority interests in certain subsidiaries, less 
goodwill.  The Company's "Tier 2 capital" consists of: (i) a limited amount 
of allowance for loan losses ("ALL"); and (ii) term subordinated debt. The 
inclusion of elements of Tier 2 capital is subject to certain other 
requirements and limitations of the federal banking agencies. The federal 
banking agencies require a minimum ratio of qualifying total capital to 
risk-adjusted assets of 8% and a minimum ratio of Tier 1 capital to 
risk-adjusted assets of 4%. 

     Federally supervised banks are currently required to report deferred tax 
assets in accordance with SFAS No. 109. The federal banking agencies issued 
final rules governing banks and bank holding companies, which became 
effective April 1, 1995 and which limit the amount of deferred tax assets 
that are allowable in computing an institution's regulatory capital. Deferred 
tax assets that can be realized for taxes paid in prior carryback years and 
from future reversals of existing taxable temporary differences are generally 
not limited. Deferred tax assets that can only be realized through future 
taxable earnings are limited for regulatory capital purposes to the lesser of 
(i) the amount that can be realized within one year of the quarter-end report 
date, based on projected taxable income for that year or (ii) 10% of Tier 1 
capital. The amount of any deferred tax in excess of this limit would be 
excluded from Tier 1 capital and total assets and regulatory capital 
calculations.

                                     -9-


     In addition to the risked-based guidelines, federal banking regulators 
require banking organizations to maintain a minimum amount of Tier 1 capital 
to total assets, referred to as the "leverage ratio." For a banking 
organization rated in the highest of the five categories used by regulators 
to rate banking organizations, the minimum leverage ratio of Tier 1 capital 
to total assets must be at least 5%. See "Prompt Corrective Action and Other 
Enforcement Mechanisms." In addition to the uniform risk-based capital 
guidelines and leverage ratios that apply across the industry, the regulators 
have the discretion to set individual minimum capital requirements for 
specific institutions at rates significantly above the minimum guidelines and 
ratios. FIBS and the Banks are all rated as Well Capitalized (as defined 
below). 

     In June 1996, the federal banking agencies adopted a joint agency policy 
statement to provide guidance on managing interest rate risk. These agencies 
indicated that the adequacy and effectiveness of a bank's interest rate risk 
management process and the level of its interest rate exposures are critical 
factors in the agencies' evaluation of the bank's capital adequacy. A bank 
with material weaknesses in its risk management process or high levels of 
exposure relative to its capital will be directed by the agencies to take 
corrective action. Such actions will include recommendations or directions to 
raise additional capital, strengthen management expertise, improve management 
information and measurement systems, reduce levels of exposure, or some 
combination thereof depending upon the individual institution's 
circumstances. This policy statement augments the August 1995 regulations 
adopted by the federal banking agencies which addressed risk-based capital 
standards for interest rate risk. 

     Future changes in regulations or practices could further reduce the 
amount of capital recognized for purposes of capital adequacy. Such a change 
could affect the ability of the Banks to grow and could restrict the amount 
of profits, if any, available for the payment of dividends. For information 
concerning the capital ratios of FIBS, see Part II, Item 7, "Management's 
Discussion and Analysis of Financial Condition and Results of 
Operations-Financial Condition-Capital Resources." 

PROMPT CORRECTIVE ACTION AND OTHER ENFORCEMENT MECHANISMS

     Federal law requires each federal banking agency to take prompt 
corrective action to resolve problems of insured depository institutions, 
including, without limitation, those institutions which fall below one or 
more prescribed minimum capital ratios. In accordance with federal law, each 
federal banking agency has promulgated regulations defining five categories 
in which an insured depository institution will be placed, based on the level 
of its capital ratios. The five categories are "Well Capitalized," 
"Adequately Capitalized," "Undercapitalized," "Significantly 
Undercapitalized" and "Critically Undercapitalized." An insured depository 
institution will be classified in the following categories based, in part, on 
the capital measures indicated below: 


                                                
WELL CAPITALIZED                                   ADEQUATELY CAPITALIZED
  Total risk-based capital of at least 10%,          Total risk-based capital of at least 8%,
  Tier 1 risk-based capital of 6%; and               Tier 1 risk-based capital of 4%; and
  Leverage ratio of 5%                               Leverage ratio of 4%

UNDERCAPITALIZED                                   SIGNIFICANTLY UNDERCAPITALIZED
  Total risk-based capital less than 8%,             Total risk-based capital less than 6%,
  Tier 1 risk-based capital less than 4%; or         Tier 1 risk-based capital less than 3%; or
  Leverage ratio less than 4%                        Leverage ratio less than 3%

CRITICALLY UNDERCAPITALIZED
  Tangible equity to total assets less than 2%


     An institution classified as Well Capitalized, Adequately Capitalized or 
Undercapitalized may be treated as though it were in the next lower capital 
category if the appropriate federal banking agency, after notice and 
opportunity for hearing, determines that an unsafe or unsound condition or an 
unsafe or unsound practice warrants such treatment. At each successive lower 
capital category, an insured depository institution is subject to more 
restrictions. The federal banking agencies, however, may not treat a 
Significantly Undercapitalized institution as Critically Undercapitalized 
unless its capital ratio actually warrants such treatment.

                                     -10-


     Insured depository institutions are prohibited from paying management 
fees to any controlling persons or, with certain limited exceptions, making 
capital distributions if after such transaction the institution would be 
Undercapitalized. If an insured depository institution is Undercapitalized, 
it will be closely monitored by the appropriate federal banking agency, 
subject to asset growth restrictions and required to obtain prior regulatory 
approval for acquisitions, branching and engaging in new lines of business. 
Any Undercapitalized depository institution must submit an acceptable capital 
restoration plan to the appropriate federal banking agency within 45 days 
after receiving or being deemed to have received notice, that the institution 
is Undercapitalized. The appropriate federal banking agency cannot accept a 
capital plan unless, among other things, it determines that the plan: (i) 
specifies: (a) the steps the institution will take to become Adequately 
Capitalized; (b) the levels of capital to be attained during each year in 
which the plan will be in effect; (c) how the institution will comply with 
the applicable restrictions or requirements then in effect of the Federal 
Deposit Insurance Corporation Improvement Act of 1991, as amended ("FDICIA"); 
and (d) the types and levels of activities in which the institution will 
engage; (ii) is based on realistic assumptions and is likely to succeed in 
restoring the depository institution's capital; and (iii) would not 
appreciably increase the risk (including credit risk, interest-rate risk and 
other types of risk) to which the institution is exposed. In addition, each 
company controlling an Undercapitalized depository institution must guarantee 
that the institution will comply with the capital plan until the depository 
institution has been Adequately Capitalized on average during each of four 
consecutive calendar quarters and must otherwise provide appropriate 
assurances of performance. The aggregate liability of such guarantee is 
limited to the lesser of (i) an amount equal to 5% of the depository 
institution's total assets at the time the institution became 
Undercapitalized or (ii) the amount which is necessary to bring the 
institution into compliance with all capital standards applicable to such 
institution as of the time the institution fails to comply with its capital 
restoration plan. Finally, the appropriate federal banking agency may impose 
any of the additional restrictions or sanctions that it may impose on 
Significantly Undercapitalized institutions if it determines that such action 
will further the purpose of the prompt correction action provisions. 

     An insured depository institution that is Significantly 
Undercapitalized, or is Undercapitalized and fails to submit, or in a 
material respect to implement, an acceptable capital restoration plan, is 
subject to additional restrictions and sanctions. These include, among other 
things: (i) a forced sale of voting shares to raise capital or, if grounds 
exist for appointment of a receiver or conservator, a forced merger; (ii) 
restrictions on transactions with affiliates; (iii) further limitations on 
interest rates paid on deposits; (iv) further restrictions on growth or 
required shrinkage; (v) modification or termination of specified activities; 
(vi) replacement of directors or senior executive officers; (vii) 
prohibitions on the receipt of deposits from correspondent institutions; 
(viii) restrictions on capital distributions by the holding companies of such 
institutions; (ix) required divestiture of subsidiaries by the institution; 
or (x) other restrictions as determined by the appropriate federal banking 
agency. Although the appropriate federal banking agency has discretion to 
determine which of the foregoing restrictions or sanctions it will seek to 
impose, it is required to: (i) force a sale of shares or obligations of the 
bank, or require the bank to be acquired by or combine with another 
institution; (ii) impose restrictions on affiliate transactions and (iii) 
impose restrictions on rates paid on deposits, unless it determines that such 
actions would not further the purpose of the prompt corrective action 
provisions. In addition, without the prior written approval of the 
appropriate federal banking agency, a Significantly Undercapitalized 
institution may not pay any bonus to its senior executive officers or provide 
compensation to any of them at a rate that exceeds such officer's average 
rate of base compensation during the 12 calendar months preceding the month 
in which the institution became Undercapitalized. 

     Further restrictions and sanctions are required to be imposed on insured 
depository institutions that are Critically Undercapitalized. For example, a 
Critically Undercapitalized institution generally would be prohibited from 
engaging in any material transaction other than in the ordinary course of 
business without prior regulatory approval and could not, with certain 
exceptions, make any payment of principal or interest on its subordinated 
debt beginning 60 days after becoming Critically Undercapitalized. Most 
importantly, however, except under limited circumstances, the appropriate 
federal banking agency, not later than 90 days after an insured depository 
institution becomes Critically Undercapitalized, is required to appoint a 
conservator or receiver for the institution. The board of directors of an 
insured depository institution would not be liable to the institution's 
stockholders or creditors for consenting in good faith to the appointment of 
a receiver or conservator or to an acquisition or merger as required by the 
regulator. 

     In addition to measures taken under the prompt corrective action 
provisions, commercial banking organizations may be subject to potential 
enforcement actions by the federal regulators for unsafe or unsound practices 
in conducting their businesses or for violations of any law, rule, regulation 
or any condition imposed in writing by the agency or any written agreement 
with the agency. See "Potential Enforcement Actions" herein.

                                     -11-


SAFETY AND SOUNDNESS STANDARDS

     Effective July 1995, the federal banking agencies adopted final 
guidelines establishing standards for safety and soundness, as required by 
the FDICIA. These standards are designed to identify potential safety and 
soundness concerns and ensure that action is taken to address those concerns 
before they pose a risk to the deposit insurance funds. The standards relate 
to (i) internal controls, information systems and internal audit systems; 
(ii) loan documentation; (iii) credit underwriting; (iv) asset growth; (v) 
earnings; and (vi) compensation, fees and benefits. If a federal banking 
agency determines that an institution fails to meet any of these standards, 
the agency may require the institution to submit to the agency an acceptable 
plan to achieve compliance with the standard. If the institution fails to 
submit an acceptable plan within the time allowed by the agency or fails in 
any material respect to implement an accepted plan, the agency must, by 
order, require the institution to correct the deficiency. Effective October 
1, 1996, the federal banking agencies promulgated safety and soundness 
regulations and accompanying interagency compliance guidelines on asset 
quality and earnings standards. These new guidelines provide six standards 
for establishing and maintaining a system to identify problem assets and 
prevent those assets from deteriorating. The institution should: (i) conduct 
periodic asset quality reviews to identify problem assets; (ii) estimate the 
inherent losses in those assets and establish reserves that are sufficient to 
absorb estimated losses; (iii) compare problem asset totals to capital; (iv) 
take appropriate corrective action to resolve problem assets; (v) consider 
the size and potential risks of material asset concentrations; and (vi) 
provide periodic asset reports with adequate information for management and 
the board of directors to assess the level of asset risk. These guidelines 
also set forth standards for evaluating and monitoring earnings and for 
ensuring that earnings are sufficient for the maintenance of adequate capital 
and reserves. If an institution fails to comply with a safety and soundness 
standard, the appropriate federal banking agency may require the institution 
to submit a compliance plan. Failure to submit a compliance plan or to 
implement an accepted plan may result in enforcement action. 

     In December 1993, the federal banking agencies issued an interagency 
policy statement on the ALL which, among other things, established certain 
benchmark ratios of loan loss reserves to classified assets. The benchmark 
set forth by such policy statement is the sum of (a) assets classified loss; 
(b) 50% of assets classified doubtful; (c) 15% of assets classified 
substandard; and (d) estimated credit losses on other assets over the 
upcoming 12 months. This amount is neither a "floor" nor a "safe harbor" 
level for an institution's ALL. 

PREMIUMS FOR DEPOSIT INSURANCE

     The FDIC has adopted final regulations implementing a risk-based premium 
system required by federal law, which establishes an assessment rate schedule 
ranging from nothing to 27 cents per $100 of deposits applicable to members 
of the Bank Insurance Fund ("BIF"). To determine the risk-based assessment 
for each institution, the FDIC will categorize an institution as Well 
Capitalized, Adequately Capitalized or Undercapitalized using the same 
standards used by the FDIC for its prompt corrective action regulations. For 
purposes of assessing FDIC premiums, an Undercapitalized institution will 
generally be one that does not meet either a Well Capitalized or an 
Adequately Capitalized standard. The FDIC will also assign each institution 
to one of three subgroups based upon reviews by the institution's primary 
federal or state regulator, statistical analyses of financial statements and 
other information relevant to evaluating the risk posed by the institution. 
The three supervisory categories are: financially sound with only a few minor 
weaknesses ("Group A"), demonstrates weaknesses that could result in 
significant deterioration ("Group B") and poses a substantial probability of 
loss ("Group C"). 

     The BIF assessment rates are set forth below for institutions based on 
their risk-based assessment categorization:

                 Assessment Rates Effective January 1, 1998*


                                    Group A   Group B   Group C
            ---------------------------------------------------
                                               
            Well Capitalized            0         3        17
            Adequately Capitalized      3        10        24
            Undercapitalized           10        24        27


* Assessment figures are expressed in terms of cents per $100 of deposits.

                                     -12-


     The 1996 Budget Act required banks to share in part of the interest 
payments on the Financing Corporation ("FICO") bonds which were issued to 
help fund the federal government costs associated with the savings and loan 
crisis of the late 1980s.  Effective January 1, 1998, for FICO payments, 
BIF-insured institutions, like the Banks, pay 0.64 cents per $100 in domestic 
deposits. Full pro rata sharing of FICO interest payments takes effect on 
January 1, 2000.

INTERSTATE BANKING AND BRANCHING

     Under the Banking and Branching Act, a bank holding company may obtain 
approval under the BHCA to acquire an existing bank located in another state 
without regard to state law. A bank holding company is not permitted to make 
such an acquisition if, upon consummation of the acquisition, it would 
control (a) more than 10% of the total amount of deposits of insured 
depository institutions in the United States or (b) 30% or more of the 
deposits in the state in which the bank is located. A state may limit the 
percentage of total deposits that may be held in that state by any one bank 
or bank holding company if application of such limitation does not 
discriminate against out-of-state banks or bank holding companies. An 
out-of-state bank holding company may not acquire a state bank in existence 
for less than a minimum length of time that may be prescribed by state law, 
except that a state may not impose more than a five-year age requirement. 

     The Banking and Branching Act also permits, beginning as of June 1, 
1997, mergers of insured banks located in different states and conversion of 
the branches of the acquired bank into branches of the resulting bank. Each 
state may permit such combinations earlier than June 1, 1997 and may adopt 
legislation to prohibit interstate mergers after that date in that state or 
in other states by that state's banks. The same concentration limits 
discussed in the preceding paragraph also apply to such mergers. The Banking 
and Branching Act also permits a national or state bank to establish branches 
in a state other than its home state if permitted by the laws of that state, 
subject to the same requirements and conditions as for a merger transaction. 

     On March 20, 1997, the State of Montana enacted legislation 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 Banking and 
Branching Act, thereby precluding interstate branching in Montana until 
October 1, 2001. Nevertheless, after the foregoing prohibition expires, 
competition in the Company's market areas could increase significantly. 

COMMUNITY REINVESTMENT ACT AND FAIR LENDING DEVELOPMENTS

     The Banks are subject to certain fair lending requirements and reporting 
obligations involving home mortgage lending operations and Community 
Reinvestment Act ("CRA") activities. The CRA generally requires the federal 
banking agencies to evaluate the record of a financial institution in meeting 
the credit needs of its local communities, including low and moderate income 
neighborhoods. In addition to substantial penalties and corrective measures 
that may be required for a violation of certain fair lending laws, the 
federal banking agencies may take compliance with such laws and CRA into 
account when regulating and supervising other activities. 

     In May 1995, the federal banking agencies issued final regulations which 
change the manner in which they measure a bank's compliance with its CRA 
obligations. The final regulations adopt a performance-based evaluation 
system which bases CRA ratings on an institution's actual lending, service 
and investment performance, rather than on the extent to which the 
institution conducts needs assessments, documents community outreach 
activities or complies with other procedural requirements. 

     In March 1994, the federal Interagency Task Force on Fair Lending issued 
a policy statement on discrimination in lending. The policy statement 
describes the three methods that federal agencies will use to prove 
discrimination: overt evidence of discrimination, evidence of disparate 
treatment and evidence of disparate impact. 

     In connection with its assessment of CRA performance, the appropriate 
bank regulatory agency assigns a rating of "outstanding," "satisfactory," 
"needs to improve" or "substantial noncompliance." Based on an examination 
conducted during 1997, FIB Montana and FIB Wyoming were both rated 
"satisfactory."

                                     -13-


POTENTIAL ENFORCEMENT ACTIONS

     Commercial banking organizations, such as the Banks and their 
institution-affiliated parties, which includes FIBS, may be subject to 
potential enforcement actions by the Federal Reserve and the FDIC for unsafe 
or unsound practices in conducting their businesses or for violations of any 
law, rule, regulation or any condition imposed in writing by the agency or 
any written agreement with the agency. Enforcement actions may include the 
imposition of a conservator or receiver, the issuance of a cease-and-desist 
order that can be judicially enforced, the termination of insurance of 
deposits (in the case of the Banks), the imposition of civil money penalties, 
the issuance of directives to increase capital, the issuance of formal and 
informal agreements, the issuance of removal and prohibition orders against 
institution affiliated parties and the imposition of restrictions and 
sanctions under the prompt corrective action provisions of the FDICIA. 
Additionally, a bank holding company's inability to serve as a source of 
strength to its subsidiary banking organizations could serve as an additional 
basis for a regulatory action against such bank holding company. Neither FIBS 
nor the Banks has been subject to any such enforcement actions. 

NON-BANK SUBSIDIARY

     During the fourth quarter 1997, the Company formed FIB Capital, a 
statutory business trust incorporated under Delaware law, with an initial 
capitalization of $1.2 million.  FIB Capital was formed for the exclusive 
purpose of issuing $40 million of mandatorily redeemable trust preferred 
securities ("trust preferred securities") and using the proceeds to purchase 
junior subordinated debentures ("subordinated debentures") issued by FIBS.  
The Company used proceeds from the issuance of the subordinated debentures to 
redeem the noncumulative perpetual preferred stock and to reduce revolving 
term debt.  See also "Notes to Consolidated Financial Statements - 
Mandatorily Redeemable Preferred Securities of Subsidiary Trust" of the 
financial statements included in Part IV, Item 14.

RISK FACTORS

ABILITY OF THE COMPANY TO EXECUTE ITS BUSINESS STRATEGY

     The financial performance and profitability of the Company will depend 
on its ability to execute its business strategy and manage its possible 
future growth. Although the Company believes that it has substantially 
integrated the recently acquired banks into the Company's operations, there 
can be no assurance that unforeseen issues relating to the assimilation or 
prior operations of these banks, including the emergence of any material 
undisclosed liabilities, will not materially adversely affect the Company. In 
addition, any future acquisitions or other possible future growth may present 
operating and other problems that could have a material adverse effect on the 
Company's business, financial condition and results of operations. The 
Company's financial performance will also depend on the Company's ability to 
maintain profitable operations through implementation of its strategic 
vision. Moreover, the Company's future performance is subject to a number of 
factors beyond its control, including pending and future federal and state 
banking legislation, regulatory changes, unforeseen litigation outcomes, 
inflation, lending and deposit rate changes, interest rate fluctuations, 
increased competition and economic conditions. Accordingly, there can be no 
assurance that the Company will be able to continue the growth or maintain 
the level of profitability it has recently experienced. 

INTEREST RATE RISK

     Banking companies' earnings depend largely on the relationship between 
the yield on earning assets, primarily loans and investments, and the cost of 
funds, primarily deposits and borrowings. This relationship, known as the 
interest rate spread, is subject to fluctuation and is affected by economic 
and competitive factors which influence interest rates, the volume and mix of 
interest-earning assets and interest-bearing liabilities and the level of 
non-performing assets. Fluctuations in interest rates affect the demand of 
customers for the Company's products and services. The Company is subject to 
interest rate risk to the degree that its interest-bearing liabilities 
reprice or mature more slowly or more rapidly or on a different basis than 
its interest-earning assets. Significant fluctuations in interest rates could 
have a material adverse effect on the Company's business, financial condition 
and results of operations.

                                     -14-


ECONOMIC CONDITIONS; LIMITED GEOGRAPHIC DIVERSIFICATION

     The Company's operations are located in Montana and Wyoming. As a result 
of the geographic concentration of its operations, the Company's results 
depend largely upon economic conditions in these areas. The Company believes 
the primary industries in Montana and Wyoming include agriculture, energy, 
mining, timber processing, tourism, government services, education and 
medical services. A deterioration in economic conditions in the Company's 
market areas could adversely impact the quality of the Company's loan 
portfolio and the demand for its products and services, and accordingly, 
could have a material adverse effect on the Company's business, financial 
condition and results of operations. 

GOVERNMENT REGULATION AND MONETARY POLICY

     The Company and the banking industry are subject to extensive regulation 
and supervision under federal and state laws and regulations. The 
restrictions imposed by such laws and regulations limit the manner in which 
the Company conducts its banking business, undertakes new investments and 
activities and obtains financing. This regulation is designed primarily for 
the protection of the deposit insurance funds and consumers and not to 
benefit holders of the Company's securities. Financial institution regulation 
has been the subject of significant legislation in recent years and may be 
the subject of further significant legislation in the future, none of which 
is in the control of the Company. Significant new laws or changes in, or 
repeals of, existing laws could have a material adverse effect on the 
Company's business, financial condition and results of operations. Further, 
federal monetary policy, particularly as implemented through the Federal 
Reserve System, significantly affects credit conditions for the Company, and 
any unfavorable change in these conditions could have a material adverse 
effect on the Company's business, financial condition and results of 
operations. See "Regulation and Supervision."

     The banking and financial services business in both Montana and Wyoming 
is highly competitive. The increasingly competitive environment is a result 
primarily of changes in regulation, changes in technology and product 
delivery systems and the accelerating pace of consolidation among financial 
services providers. The Banks compete for loans, deposits and customers for 
financial services with other commercial banks, savings and loan 
associations, securities and brokerage companies, mortgage companies, 
insurance companies, finance companies, money market funds, credit unions and 
other nonbank financial services providers. Several of these competitors are 
much larger in total assets and capitalization, have greater access to 
capital markets and offer a broader array of financial services than the 
Banks. Moreover, the Riegal-Neal Interstate Banking and Branching Efficiency 
Act of 1994 (the "Banking and Branching Act") has increased competition in 
the Banks' markets, particularly from larger, multi-state banks. There can be 
no assurance that the Company will be able to compete effectively in its 
markets. Furthermore, developments increasing the nature or level of 
competition could have a material adverse effect on the Company's business, 
financial condition and results of operations. See "Competition" and 
"Regulation and Supervision." 

DEPENDENCE ON KEY PERSONNEL

     The Company's success depends to a significant extent on the management 
skills of its existing executive officers and directors, many of whom have 
held officer and director positions with the Company for many years. The loss 
or unavailability of any of its key executives, including Homer A. Scott, 
Jr., Chairman of the Board, Thomas W. Scott, President and Chief Executive 
Officer or Terrill R. Moore, Senior Vice President, Chief Financial Officer 
and Secretary, could have a material adverse effect on the Company's 
business, financial condition and results of operations. See Part III, Item 
10, "Directors and Executive Officers of Registrant." 

CONTROL BY AFFILIATES

     The directors and executive officers of the Company beneficially own 
approximately 67.3% of the outstanding common stock of the Company. Many of 
these directors and executive officers are members of the Scott family, which 
collectively owns approximately 82.3% of the outstanding common stock. By 
virtue of such ownership, these affiliates are able to control the election 
of directors and the determination of the Company's business, including 
transactions involving any merger, share exchange, sale of assets outside the 
ordinary course of business and dissolution.

                                     -15-


ASSET QUALITY

     A significant source of risk for the Company arises from the possibility
that losses will be sustained by the Banks because borrowers, guarantors and
related parties may fail to perform in accordance with the terms of their loans.
The Company has adopted underwriting and credit monitoring procedures and credit
policies, including the establishment and review of the ALL, that management
believes are appropriate to mitigate this risk by assessing the likelihood of
nonperformance, tracking loan performance and diversifying the Company's credit
portfolio. Such policies and procedures, however, may not prevent unexpected
losses that could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business-Lending
Activities."

LACK OF TRADING MARKET; MARKET PRICES

     The common stock of FIBS is not actively traded, and there is no
established trading market for the stock.  There is only one class of common
stock, with 92.8% of the shares subject to contractual transfer restrictions set
forth in shareholder agreements and 7.2% held by 13 shareholders without such
restrictions.  FIBS 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 FIBS less dividends paid.  All stock not
subject to such restrictions may be 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 FIBS.  FIBS has no obligation to purchase unrestricted stock, but
has historically purchased such stock in order to reduce the amount of its stock
not subject to transfer restrictions.

     The appraised minority value of the FIBS common stock represents the
estimated fair market valuation of a minority block of such stock, taking into
account adjustments for the lack of marketability of the stock and other
factors.  This value does not represent an actual trading price between a
willing buyer and seller of the FIBS common stock in an informed, arm's-length
transaction.  As such, the appraised minority value is only an estimate as of a
specific date, and there can be no assurance that such appraisal is an
indication of the actual value holders of the FIBS common stock may realize with
respect to shares held by them.  Moreover, the estimated fair market value of
the FIBS common stock may be materially different at any date other than the
valuation dates indicated above.

     FIBS 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 FIBS to repurchase common stock to
maintain a shareholder base with restrictions on sale or transfer of the stock.
In the last three calendar years (1995-1997) FIBS has redeemed a total of 94,752
shares of common stock, all of which was restricted by the shareholder
agreements.  FIBS has redeemed the stock at the price determined in accordance
with the shareholder agreements.  FIBS has no present intention to change its
historical practice for redemption of stock, but no assurances can be provided
that FIBS will not change or end its practice of redeeming stock.  Furthermore,
FIBS redemptions of stock are subject to corporate law and regulatory
restrictions which could prevent stock redemptions.

     There is a limited public market for the trust preferred securities.
Future trading prices of the trust preferred securities depend on many factors
including, among other things, prevailing interest rates, the operating results
and financial condition of the Company and the market for similar securities.
As a result of the existence of FIBS's right to defer interest payments on or,
subject to prior approval of the Federal Reserve if then required under
applicable capital guidelines or policies of the Federal Reserve, shorten the
stated maturity of the subordinated debentures, the market price of the trust
preferred securities may be more volatile than the market prices of subordinated
debentures that are not subject to such optional deferrals or reduction in
maturity.  There can be no assurance as to the market prices for the trust
preferred securities or the subordinated debentures that may be distributed in
exchange for the trust preferred securities if the Company exercises its right
to dissolve FIB Capital.

                  ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY
                         AND RELATED STOCKHOLDER MATTERS

DESCRIPTION OF FIBS CAPITAL STOCK

     The authorized capital stock of FIBS consists of 20,000,000 shares of
common stock without par value, of which 8,030,799 shares were outstanding as of
December 31, 1997, and 100,000 shares of preferred stock without par value, none
of which were outstanding as of December 31, 1997.

COMMON STOCK

     Each share of the common 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 the holders of the
preferred stock.  Voting for directors is noncumulative.

                                     -17-


     Subject to the preferential rights of any preferred stock that may at the
time be outstanding, each share of common 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.  In the event of a liquidation, dissolution
or winding up of the Company, the holders of common 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 common stock have no conversion rights or
pre-emptive or other rights to subscribe for any additional shares of common
stock or for other securities.  All outstanding common stock is fully paid and
non-assessable.

     The common stock of FIBS is not actively traded, and there is no
established trading market for the stock.  There is only one class of common
stock, with 92.8% of the shares subject to contractual transfer restrictions set
forth in shareholder agreements and 7.2% held by 13 shareholders without such
restrictions.  FIBS has the right of first refusal to purchase the restricted
stock at the minority appraised value per share based on the most recent
quarterly appraisal available to FIBS less dividends paid.  All stock not
subject to such restrictions may be sold at a price per share that is acceptable
to the shareholder.

     Quarter-end minority appraisal values for the past two years, determined by
Alex Sheshunoff & Co. Investment Banking are as follows:



                                      Appraised
     Valuation As Of(1)           Minority Value(2)
     ------------------           -----------------
                               
     December 31, 1995                  $18.75
     March 31, 1996                      19.38
     June 30, 1996                       19.88
     September 30, 1996                  20.25
     December 31, 1996                   21.50
     March 31, 1997                      21.50
     June 30, 1997                       23.75
     September 30, 1997                  25.00
     December 31, 1997                   29.00


     (1)  Sales of stock between dates at which updated valuations are received
          are adjusted for cash dividends paid.
     (2)  Prior to dividends.

     As of December 31, 1997, options for 123,204 shares of the FIBS common
stock were outstanding at various exercise prices, ranging from $4.56 to $20.05.
The aggregate cash proceeds to be received by FIBS upon exercise of all options
outstanding at December 31, 1997 would be $1,568.9, or a weighted average
exercise price of $12.73 per share.

     The book value per share of FIBS common stock as of December 31, 1997 was
$18.14.  The appraised minority value as of December 31, 1997 was $29.00.  The
appraised minority value of the FIBS common stock represents the estimated fair
market valuation of a minority block of such stock, taking into account
adjustments for the lack of marketability of the stock and other factors.  This
value does not represent an actual trading price between a willing buyer and
seller of the FIBS common stock in an informed, arm's-length transaction.  As
such, the appraised minority value is only an estimate as of a specific date,
and there can be no assurance that such appraisal is an indication of the actual
value holders of the FIBS common stock may realize with respect to shares held
by them.  Moreover, the estimated fair market value of the FIBS common stock may
be materially different at any date other than the valuation dates indicated
above.

     Resale of FIBS stock may be restricted pursuant to the Securities Act of
1933 and applicable state securities laws.  In addition, most shares of FIBS
stock are subject to one of two shareholders' agreements.  Members of the Scott
family, as majority shareholders of FIBS, are subject to a shareholder's
agreement ("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 FIBS's approval, to the Company's officers,
directors, advisory directors, or to the Savings Plan.

                                     -18-


     Shareholders of the Company who are not Scott family members, with the
exception of 13 shareholders who own an aggregate of 580,284 shares of
unrestricted stock, are subject to a shareholder's agreement ("Shareholder's
Agreement").  The Shareholder's Agreement grants FIBS the option to purchase the
stock 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
the Company, and 5) total disability of the shareholder.  Stock subject to the
Shareholder's Agreement may not be sold or transferred by the shareholder
without triggering FIBS's option to acquire the stock in accordance with the
terms of the Shareholder's Agreement.  In addition, the Shareholder's Agreement
allows FIBS to repurchase any of the FIBS stock acquired by the shareholder
after January 1, 1994 if FIBS 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.

     Purchases of FIBS common stock made through FIBS's Savings Plan are not
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
FIBS stock.  While FIBS has no obligation to repurchase the stock, it is
possible that FIBS will repurchase FIBS stock sold out of the Savings Plan.
Any such repurchases would be upon terms set by the Savings Plan trustee and
accepted by FIBS.

     There are 400 record shareholders of FIBS as of December 31, 1997,
including the Company's Savings Plan as trustee for shares held on behalf of 586
individual participants in the plan.  221 individuals in the Savings Plan also
own shares of FIBS stock outside of the Plan.  The Plan is administered by the
Trust Department of FIB Montana, which votes the shares based on the
instructions of each participant.  In the event the participant does not provide
the Trustee with instructions, the Trustee will vote those shares in accordance
with voting instructions received from a majority of the participants in the
Plan.

DIVIDENDS

     It is the policy of FIBS 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 historically been determined based upon a percentage
of net income for the calendar quarter immediately preceding the dividend
payment date.  Effective with the dividend for the fourth quarter of 1995 paid
in January 1996, the dividend has been 30% of quarterly net income.  The Board
of Directors of FIBS has no current intention to change its dividend policy, but
no assurance can be given that the Board may not, in the future, change or
eliminate the payment of dividends.

     Historical quarterly dividends for 1996 and 1997 are as follows:



          Month
                             Declared        Amount      Total Cash
         Quarter             and Paid      Per Share      Dividend
     ----------------      ------------    ---------    -----------
                                               
     1st quarter 1996      April 1996       $ .21       $ 1,572,131
     2nd quarter 1996      July 1996          .19         1,505,941
     3rd quarter 1996      October 1996       .20         1,564,878
     4th quarter 1996      January 1997       .22         1,721,584
     1st quarter 1997      April 1997         .25         1,934,003
     2nd quarter 1997      July 1997          .25         1,991,274
     3rd quarter 1997      October 1997       .26         2,089,967
     4th quarter 1997      January 1998       .22         1,765,154


     Lower quarterly net income during the fourth quarter 1997 resulted in a
decrease in dividends paid for that period.  Fourth quarter charges against net
income consisted primarily of a non-recurring charge related to the
establishment of reserves toward prepayments of indirect dealer loans and
additional severance accruals.

                                     -19-


DIVIDEND RESTRICTIONS

     The holders of common stock will be entitled to dividends when, as and if
declared by FIBS's Board of Directors out of funds legally available therefor.
Under the Company's revolving term loan, the Company is prohibited from
declaring or paying any dividends to common stockholders in excess of 33% of net
income for the immediately preceding year.  The Company has also agreed that the
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 the Banks will at all times maintain capital at adequately
capitalized levels.  The loan restrictions limit the funds available for the
payment of dividends from the Banks to FIBS and from FIBS to its stockholders.

     Under Montana banking law, FIB Montana may not declare dividends in excess
of its 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.  As a Federal Reserve member bank, FIB Montana may not,
without the consent of the Federal Reserve, declare dividends in a calendar year
which, when aggregated with prior dividends in that calendar year, exceed the
calendar year net profits of FIB Montana together with retained earnings for the
prior two calendar years.  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 and Federal
Reserve) 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 FIBS or any of the Banks could pay.  See
Part I, Item 1, "Regulation and Supervision."

PREFERRED STOCK

     The authorized capital stock of FIBS includes 100,000 shares of preferred
stock.  FIBS's Board of Directors is authorized, without approval of the holders
of Common Stock, to provide for the issuance of 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.  FIBS's Board of Directors
may cause FIBS to issue preferred stock with voting, conversion and other rights
that could adversely affect the holders of the common 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 FIBS, before any distribution or payment may be made to the holders of common
stock, the holders of preferred stock would be entitled to be paid in full with
the respective amounts fixed by FIBS's Board of Directors in the resolution or
resolutions authorizing the issuance 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 holders
of preferred stock are entitled to receive, the remaining assets of FIBS 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 FIBS into or with any other corporation or
corporations would not be deemed a liquidation, dissolution, or winding up of
the affairs of FIBS.

SALES OF UNREGISTERED SECURITIES

     During 1997, the Company issued 12,232 unregistered shares of its common
stock to nine employees exercising stock options.  Exercise prices ranged from
$4.56 to $20.05 with an average exercise price of $5.83.  These sales were made
pursuant to the exemption from registration under Section 4(2) of the Securities
Act of 1933.  For additional information regarding stock options, see "Notes to
Consolidated Financial Statements - Employee Benefit Plans" included in Part IV,
Item 14.

     ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS

OVERVIEW

     The following discussion and analysis is intended to provide greater 
details of the results of operations and financial condition of the Company. 
The following discussion should be read in conjunction with the information 
under Part II, Item 6, "Selected Consolidated Financial Data" and the 
Company's consolidated financial statements, including the notes thereto, and 
other financial data appearing elsewhere in this document.  Certain 
statements included in the following discussion constitute "forward-looking 
statements" which involve various risks and uncertainties.  The Company's 
actual results may differ significantly from those anticipated in such 
forward-looking statements. Factors that might cause such a difference 
include, without limitation, the ability of the Company to execute its 
business strategy, interest rate risk, economic conditions, government 
regulation, competition and asset quality.  For additional information 
concerning these and other factors, see Part I, Item 1, "Business - Risk 
Factors."

     The Company, through the Banks, operates 32 banking offices in 23 
communities throughout Montana and Wyoming. The Company's income is derived 
primarily from the net interest income and other operating income. Net 
interest income consists of the excess of interest income, received primarily 
on customer loans and investment securities, over interest expense, paid 
principally on customer deposits and indebtedness. Other operating income 
primarily includes service charges on deposit accounts, data processing fees 
and income from fiduciary activities. 

     The Company has continued to increase earnings during the periods 
reported herein while expanding its operations. A majority of the Company's 
growth in recent years has resulted from acquisitions of other banks. In 
October 1996, the Company acquired First Interstate Bank of Montana, N.A. and 
First Interstate Bank of Wyoming, N.A., which collectively included six 
branch banks (the "FIBNA Banks"). In December 1996, the Company acquired 
Mountain Bank of Whitefish ("FIB Whitefish"), which included two branch 
locations. Immediately prior to the acquisitions, the FIBNA Banks had assets 
of $553.2 million and deposits of $423.9 million, and FIB Whitefish had 
assets of $66.9 million and deposits of $54.4 million. Prior to the 
acquisition, the FIBNA Banks were operated as branch locations without 
independent administrative support, data processing and other required 
services. In connection with the acquisition, the Company increased its 
staffing at both the holding company and branch levels to provide the 
administrative, data processing and other operational support to facilitate 
integration and operation of such banks. 

     The acquisitions of the FIBNA Banks and FIB Whitefish (collectively, the 
"Acquired Banks") were accounted for under the purchase method of accounting. 
Amortization of goodwill resulting from the acquisitions totaled 
approximately $1.8 million in 1997.  The Company believes that the Acquired 
Banks have been substantially integrated into the Company's operations. 

RESULTS OF OPERATIONS

     The Company's increased earnings and expansion of operations have been 
effected through a successful combination of acquisitions and internal 
growth. The internal growth experienced by the Company is reflected by an 
increased volume of customer loans and deposits, without giving effect to 
such acquisitions. The Company's internal growth has largely been 
accomplished through its effective offering and promotion of competitively 
priced products and services.  Net income increased 21.7% to $25.9 million in 
1997 from $21.2 million in 1996. This increase resulted from internal growth 
and earnings provided by the Acquired Banks.  Net income increased 22.5% to 
$21.2 million in 1996 from $17.3 million in 1995, due principally to internal 
growth. 

     Net income during the fourth quarter 1997 decreased 17.1% from the third 
quarter.  This decrease resulted from fourth quarter charges including a 
non-recurring charge related to the establishment of reserves toward 
prepayment of indirect dealer loans and additional severance accruals.

NET INTEREST INCOME

     Net interest income is the largest source of the Company's operating 
income. As discussed above, net interest income is derived from interest, 
dividends and fees received from interest-earning assets, less interest 
expense incurred on interest-bearing liabilities. Interest earning assets 
primarily include loans and investment securities. Interest-bearing 
liabilities primarily include deposits and various forms of indebtedness. 

                                    - 23 -


     Net interest income increased 37.2% to $93.1 million from $67.9 million 
in 1996. This increase resulted primarily from the incremental net interest 
income provided by the Acquired Banks.  Net interest income increased 19.1% 
to $67.9 million in 1996 from $57.0 million in 1995. This increase resulted 
primarily from the Acquired Banks and from a higher volume of loans due to 
internal growth.

     The following table presents, for the periods indicated, condensed 
average balance sheet information for the Company, together with interest 
income and yields earned on average interest-earning assets, and interest 
expense and rates paid on average interest-bearing liabilities.  Average 
balances are averaged daily balances.

     repurchase agreements and other borrowed funds.  Excludes long-term debt.

(4)  Net yield on interest-earning assets during the period equals (i) the
     difference between interest income on interest-earning assets and the
     interest expense on interest-bearing liabilities and trust preferred
     securities, divided by (ii) average interest-earning assets for the period.

     The most significant impact on the Company's net interest income between
periods is derived from the interaction of changes in the volume of and rates
earned or paid on interest-earning assets and interest-bearing liabilities. The
volume of loans, investment securities and other interest-earning assets,
compared to the volume of interest-bearing deposits and indebtedness, combined
with the spread, produces the changes in the net interest income between
periods. 
  
     The table below sets forth, for the periods indicated, a summary of the
changes in interest income and interest expense resulting from estimated changes
in average asset and liability balances (volume) and estimated changes in
average interest rates (rate). Changes which are not due solely to volume or
rate have been allocated to these categories based on the respective percent
changes in average volume and average rate as they compare to each other.

(1)  Interest income and average rates for tax exempt loans and securities are
     presented on a fully-taxable equivalent basis.

(2)  Includes interest on Federal funds purchased, securities sold under
     repurchase agreements and other borrowed funds.

     Interest income increased 40.6% to $165.8 million in 1997 from $117.9 
million in 1996. This increase was due primarily to the significant increase 
in loans, principally due to the Acquired Banks.  The yield on average 
interest-earning assets during 1997 was 8.87% compared to 8.91% during 1996. 

     In 1996, interest income increased 19.2% to $117.9 million from $99.0 
million in 1995. This increase resulted primarily from the Acquired Banks, 
offset by a slight decrease of six basis points in the yield on average 
interest-earning assets from 8.97% in 1995 to 8.91% in 1996. 

     Customer loan fees, included in interest income, increased 22.0% to $6.1 
million in 1997 from $5.0 million in 1996 due to loan fees generated by the 
Acquired Banks.  Loan fees increased 23.5% to $5.0 million in 1996 from $4.1 
million in 1995.  The most significant increases from 1995 to 1996 were in 
commercial, consumer and real estate loan fees.

                                    - 25 -


     Interest expense increased 45.3% to $72.7 million during 1997 from $50.0 
million in 1996. This increase was due primarily to the customer deposits and 
indebtedness incurred in connection with the Acquired Banks.  The rate on 
average interest-bearing liabilities and trust preferred securities of 4.55% 
in 1997 increased 11 basis points from 4.44% in 1996. 

     Interest expense increased 19.2% to $50.0 million in 1996 from $41.9 
million in 1995. The increase resulted primarily from the customer deposits 
and indebtedness incurred with respect to the Acquired Banks, offset in part 
by a slight decrease of eight basis points in the rate on average 
interest-bearing liabilities from 4.52% in 1995 to 4.44% in 1996. 

PROVISION FOR LOAN LOSSES

     The provision for loan losses creates an allowance for future loan 
losses. The loan loss provision for each year is dependent on many factors, 
including loan growth, net charge-offs, changes in the composition of the 
loan portfolio, delinquencies, management's assessment of the quality of the 
loan portfolio, the value of the underlying collateral on problem loans and 
the general economic conditions in the Company's markets. The Company 
performs a quarterly assessment of the risk inherent in its loan portfolio, 
as well as a detailed review of each asset determined to have identified 
weaknesses. Based on this analysis, which includes reviewing historical loss 
trends, current economic conditions, industry concentrations and specific 
reviews of assets classified with identified weaknesses, the Company makes 
provisions for potential loan losses. Specific allocations are made for loans 
where the probability of a loss can be defined and reasonably determined, 
while the balance of the provisions for loan losses are based on historical 
data, delinquency trends, economic conditions in the Company's markets and 
industry averages. Annual fluctuation in the provision for loan losses result 
from management's assessment of the adequacy of the allowance for loan 
losses, and ultimate loan losses may vary from current estimates. 
  
     The provision for loan losses increased 10.3% to $4.2 million in 1997 from
$3.8 million in 1996.  The increase resulted from higher loan volumes resulting
from the 1996 acquisitions. 
  
     The provision for loan losses increased 136.0% to $3.8 million in 1996 
from $1.6 million in 1995. Of the increase, approximately $500,000 was 
associated with the Acquired Banks. The remaining increase of $1.7 million 
was due principally to higher loan volumes and an increase in non-performing 
and classified assets. Non-performing loans, comprised of non-accrual loans 
and accruing loans past due 90 days or more and restructured loans, increased 
only slightly to 1.1% of loans outstanding at December 31, 1996 from 0.8% at 
December 31, 1995. 

OTHER OPERATING INCOME

     The principal sources of other operating income include service charges 
on deposit accounts, data processing fees, income from fiduciary activities, 
comprised principally of fees earned on trust assets, and other service 
charges, commissions and fees. Other operating income increased 12.2% to 
$26.8 million in 1997 from $23.9 million in 1996. This increase was 
attributable primarily to income provided by the Acquired Banks. Without 
giving effect to the Acquired Banks, operating income from each of the four 
principal categories except other service charges showed increases in 1997 
over 1996.  These increases, however, were partially offset by one-time 
accounting adjustments, primarily with respect to data processing fees, made 
in January 1996. Increases in other operating income from 1996 to 1997 and 
from 1995 to 1996 were a function of changes in each of the principal 
categories, as discussed below. 

     Service charges on deposit accounts increased 27.1% to $9.9 million in 
1997 from $7.8 million in 1996 and 18.7% to $7.8 million in 1996 from $6.5 
million in 1995.  Of these increases, approximately $740,000 in 1997 and 
$563,000 in 1996 were attributable to the Acquired Banks, with the remainder 
resulting primarily from increased overdraft fees. 

     As discussed above, increases in operating income from data processing 
services for 1997 compared to the 1996 were mostly offset as a result of 
non-recurring accounting adjustments of $300,000 made in January 1996. The 
Company serviced 630 locations in its ATM network at December 31, 1997 
compared to 477 locations at December 31, 1996. Data processing fees 
increased 18.2% to $7.3 million in 1996 from $6.2 million in 1995 due 
primarily to a greater number of data processing customers using the 
Company's ATM network and a corresponding increase in transaction volumes. 
Since 1995, the Company's network expanded from 216 ATM locations at December 
31, 1994 to 343 locations at year-end 1995, 477 locations at year-end 1996, 
and to 630 locations at year-end 1997.  Although continued expansion of the 
Company's ATM network and increases in data processing fees are expected to 
continue, the Company does not expect to continue the rate of growth 
experienced in 1995, 1996 and 1997.  There were no increases in basic charges 
for data processing services in 1997, 1996 or 1995.

                                    - 26 -


     Revenues from fiduciary activities increased 29.2% to $4.1 million in 
1997 from $3.2 million in 1996 and 20.7% to $3.2 million in 1996 from $2.6 
million in 1995.  Of these increases, approximately $889,000 in 1997 and 
$243,000 in 1996 were attributable to trust services provided by the Acquired 
Banks, with the remainder resulting from increases in the value of assets 
under trust management.

     In addition to the principal categories discussed above, other income 
decreased 41.3% to $1.7 million in 1997 from $2.8 million in 1996 and 
increased 217.0% to $2.8 million in 1996 from $888,000 in 1995.  The increase 
in 1996 and decrease in 1997 was primarily attributable to the sale of 
certain merchant credit card processing assets at a gain of $1.4 million in 
1996.  The sale included alignment with a third-party credit card processing 
provider that has enhanced the Company's ability to compete in this highly 
specialized area. 

OTHER OPERATING EXPENSES

     Other operating expenses increased 38.8% to $74.1 million in 1997 from 
$53.4 in 1996. This increase resulted primarily from both direct and indirect 
expenses attributable to the Acquired Banks. Direct expenses totaled 
approximately $16.1 million in 1997. A significant portion of the remaining 
increase was due to various indirect expenses associated with the Company's 
need to increase its data processing support and other operational services 
to the FIBNA Banks which had been previously operated as dependent branch 
offices prior to their acquisition by the Company. The increases in 
administrative personnel and other resources to provide such support and 
services were necessary to facilitate integration of such banks into the 
Company's operations. In addition, goodwill associated with the acquisition 
of the Acquired Banks resulted in increased amortization expense of 
approximately $1.8 million in 1997. 

     In 1996, other operating expenses increased 16.1% to $53.4 million from 
$46.0 million in 1995. Of this increase, approximately $6.3 million was 
attributable to direct and indirect expenses resulting from the Acquired 
Banks and acquisitions in 1995.

     Increases in salaries, wages and benefits from 1996 to 1997 and from 
1995 to 1996 were due primarily to the direct and indirect expense 
attributable to the bank acquisitions, as discussed above. The indirect 
expenses were related particularly to the Company's data processing division 
and bank operation centers. The remainder of the increases in salaries, wages 
and benefits during these periods were principally inflationary in nature.  
Given the Company's increasing data processing and transaction volumes, 
together with the expansion of its ATM network, employee and related 
compensation expenses are expected to continue to increase, but at a slower 
rate than has been experienced over the periods presented. 

     Occupancy and furniture and equipment expenses have increased over the 
periods primarily as a result of the additional facilities associated with 
the bank acquisitions, the expansion of the ATM network and additional 
equipment used in the data processing division. Furthermore, these expenses 
have increased due to higher depreciation, maintenance and other costs 
related to the foregoing items and various other computer hardware and 
software, including upgrades, used in the Company's operations. 

     FDIC deposit insurance premiums increased to $206,000 in 1997 from 
$5,000 in 1996. This increase resulted from an increase in FDIC FICO bond 
assessment effective January 1, 1997. The significant decreases in premiums 
from 1995 to 1996 were due to a substantial FDIC rate reduction in 1996. The 
FDIC rates reflect the Company's "well-capitalized" rating by the FDIC. 

     OREO losses, including provisions for losses on OREO, are included net 
of any gains on sales of OREO. Variations in net OREO expense during the 
periods resulted principally from fluctuations in such gains.  These gains 
are anticipated to decline as the number and value of OREO properties 
decrease. OREO expense is directly related to prevailing economic conditions, 
and such expense could increase significantly should an unfavorable shift 
occur in the economic conditions of the Company's markets. 

     Other expenses primarily include advertising and public relations costs, 
legal, audit and other professional fees, and office supply, postage and 
telephone expenses. Other expenses increased in 1997 over 1996 as a result of 
the direct and indirect costs associated with the Acquired Banks. Exclusive 
of these costs, during 1997 compared to 1996, other expenses increased (i) 
approximately $484,000 due principally to consulting fees associated with 
revision of the Company's employee job evaluation system and accruals for 
financial planning activities, and (ii) approximately $319,000 due to 
additional accruals for the increased value of stock appreciation rights 
resulting from a 23% increase in the appraised value of the Company's Common 
Stock during 1997. The increases in other expenses from 1995 to 1997 were due 
primarily to the direct and indirect costs related to the Acquired Banks and 
bank acquisitions in 1995.

December 31, 1997, 1996 and 1995, respectively.   Pretax earnings subject to 
Montana state income tax decreased to approximately 57% of consolidated 
pretax earnings in 1997 from approximately 67% of consolidated pretax 
earnings in 1996 resulting in a lower effective state tax rate.

FINANCIAL CONDITION

     Total assets increased 8.3% to $2,235 million as of December 31, 1997 
from $2,064 million as of December 31, 1996. This increase resulted primarily 
from internal growth in the Company's loan portfolio funded by increases in 
repurchase agreements and deposits. Total assets increased 52.7% to $2,064 
million as of December 31, 1996 from $1,351.2 million as of December 31, 
1995. This increase was due principally to the significant increases in loans 
and investment securities provided by the bank acquisitions in 1995, funded 
by growth in deposits and increases in indebtedness.

LOANS

     Total loans increased 6.9% to $1,470 million as of December 31, 1997 
from $1,375 million as of December 31, 1996. As shown below, all categories 
of loans except real estate loans showed increases in volumes during this 
period due to continued strong economic conditions in the Company's markets 
and internal growth resulting from the Company's marketing activities.  The 
growth in loans during 1997 was slightly lower than the growth rate during 
1996 due primarily to a slowing in the growth of consumer and real estate 
loans. 

     As of December 31, 1996, total loans increased 58.0% to $1,375 million 
from $870 million as of December 31, 1995. This increase was attributable to 
the growth in the loan portfolio provided by the Acquired Banks, and to a 
lesser extent, internal growth which reflected continued favorable economic 
conditions. 

     The Company's loan portfolio consists of a mix of commercial, consumer, 
real estate, agricultural and other loans, including fixed and variable rate 
loans. Fluctuations in the loan portfolio are directly related to the 
economies of the communities served by the Company. Thus, the Company's 
borrowers could be adversely impacted by a downturn in these sectors of the 
economy which could have a material adverse effect on the borrowers' 
abilities to repay their loans. 

     The following tables present the composition of the Company's loan 
portfolio as of the dates indicated:

INVESTMENT SECURITIES

     The Company's investment portfolio is managed to result in the highest 
yield while meeting the Company's liquidity needs and utilizing pledging 
requirements for deposits of state and political subdivisions and securities 
sold under repurchase agreements. The portfolio is comprised of U.S. Treasury 
securities, U.S. government agency securities, tax exempt securities, 
corporate securities, other mortgage-backed securities, and other equity 
securities. Federal funds sold are additional investments which are not 
classified as investment securities. Investment securities classified as 
available-for-sale are recorded at fair market value, while investment 
securities classified as held-to-maturity are recorded at cost. Unrealized 
gains or losses, net of the deferred tax effect, are reported as increases or 
decreases in stockholders' equity for available-for-sale securities. 

     Investment securities increased 5.5% to $426 million as of December 31, 
1997 from $404 million as of December 31, 1996 as a result of growth in 
funding sources exceeding loan growth.  Investment securities increased 56.0% 
to $404 million as of December 31, 1996 from $259 million as of December 31, 
1995. This increase resulted from the substantial investment securities held 
by the Acquired Banks at the time of acquisition. As of December 31, 1997, 
there were no concentrations of investments greater than 10% of the Company's 
stockholders' equity in any individual security issuer, other than the U.S. 
Treasury and U.S. Government agencies. 

     The following table sets forth the book value, percentage of total 
investment securities and average yield for the Company's investment 
securities as of December 31, 1997.

DEPOSITS

     The Company emphasizes developing total client relationships with its 
customers in order to increase its core deposit base, which is the Company's 
primary funding source. The Company's deposits consist primarily of the 
following interest bearing accounts: demand deposits, savings accounts, IRAs 
and time deposits (CDs). For additional information concerning the Company's 
deposits, including its use of repurchase agreements, as discussed below, see 
Part I, Item 1, "Business-Deposits."

                                      -30-


     Deposits increased 7.5% to $1,805 million as of December 31, 1997, as 
compared to $1,679 million as of December 31, 1996 due to internal growth in 
1997.  Deposits increased 52.8% to $1,679 million as of December 31, 1996 
from $1,099 million as of December 31, 1995. This increase resulted 
principally from the deposits of the Acquired Banks combined with internal 
growth.  For additional information concerning customer deposits as of 
December 31, 1997 and 1996, see "Notes to Consolidated Financial Statements - 
Deposits" included in Part IV, Item 14.

OTHER BORROWINGS

     In addition to deposits, the Company also uses repurchase agreements 
with commercial depositors as significant sources of funding and, on a 
seasonal basis, federal funds purchased.

     The following table sets forth certain information regarding these two 
sources of funding as of the dates indicated:

NON-PERFORMING AND CLASSIFIED ASSETS

     Federal regulations require that each financial institution classify its 
assets on a regular basis. Management generally places loans on non-accrual 
when they become 90 days past due, unless they are well secured and in the 
process of collection. When a loan is placed on non-accrual status, any 
interest previously accrued but not collected is reversed from income. Loans 
are charged off when management determines that collection has become 
unlikely. Restructured loans are those where the Company has granted a 
concession on the interest paid or original repayment terms due to financial 
difficulties of the borrower. OREO consists of real property acquired through 
foreclosure on the related collateral underlying defaulted loans. 

     The following table sets forth information regarding non-performing 
assets as of the dates indicated:

     Non-performing loans increased 3.2% to $15 million as of December 31, 
1997 as compared to $15 million as of December 31, 1996 due to slight 
deteriorations in all market sectors.  Non-performing loans increased 111.6% 
to $15 million at December 31, 1996 from $7 million at December 31, 1995.  
The increase was due to the non-performing loans held by the Acquired Banks, 
an increase in the loan portfolio and a slight deterioration in the 
agricultural and consumer market sector. Approximately $763,000, $405,000, 
$318,000, $296,000 and $440,000 of gross interest income would have been 
accrued if all loans on non-accrual had been current in accordance with their 
original terms for the years ended December 31, 1997, 1996, 1995, 1994 and 
1993, respectively.

     The Company records OREO at the lower of carrying value or fair value 
less estimated costs to sell. Estimated losses that result from the ongoing 
periodic valuation of these properties are charged to earnings with a 
provision for losses on foreclosed property in the period in which they are 
identified. 

     The Company reviews and classifies its loans on a regular basis 
according to three classifications: "Substandard," "Doubtful" and "Loss." 
Substandard loans are inadequately protected by the current sound worth and 
paying capacity of the obligor or of the collateral pledged.  Doubtful loans 
have the weaknesses of substandard loans with the additional characteristic 
that the weaknesses make collection or liquidation in full, on the basis of 
currently existing facts, conditions and values, highly questionable and 
improbable.  Loans classified as Loss loans are considered uncollectible and 
of such little value that their continuance as bankable assets is not 
warranted.

     The following table sets forth classified loans as of the dates 
indicated. 



As of December 31,                                         1997       1996       1995

     Loans classified as substandard increased 70.9% to $34,161 as of 
December 31, 1997.  Approximately $9 million of the increase is the result of 
downgrading the loans of two agricultural borrowers and three commercial 
borrowers.  The remaining increase is principally due to increases in loan 
volume, combined with a slight deterioration of the credit quality of 
consumer loans, which are generally classified as substandard upon becoming 
90 days past due.

     With the exception of these classified loans, management is not aware of 
any loans as of December 31, 1997 where the known credit problems of the 
borrowers would cause management to have serious doubts as to the ability of 
such borrowers to comply with their present loan repayment terms and which 
would result in such loans being included in the non-performing asset table 
above at some future date. Management cannot, however, predict the extent to 
which economic conditions in the Company's market areas may worsen or the 
full impact such conditions may have on the Company's loan portfolio. 
Accordingly, there can be no assurances that other loans will not become 90 
days or more past due, be placed on non-accrual status or become restructured 
loans or OREO in the future. 

ALLOWANCE FOR LOAN LOSSES

     The allowance for loan losses is established through a provision for 
loan losses based on management's evaluation of risk inherent in its loan 
portfolio and economic conditions in the Company's market areas. See 
"Provision for Loan Losses" herein. The allowance is increased by provisions 
charged against earnings and reduced by net loan charge-offs.  Consumer loans 
are generally charged off when they become 120 days past due.  Other loans, 
or portions thereof, are charged off when they become 180 days past due 
unless they are well-secured and in the process of collection.  Recoveries 
are generally recorded only when cash payments are received.

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


     For the year ended December 31, 1997, net charge-offs were $4 million 
and the provision for loan losses was $4 million. These two line items show 
increases from prior comparative periods due to the expanded loan portfolio 
resulting primarily from the Acquired Banks. As of December 31, 1997, the 
allowance for loan losses was $28.2 million, representing an increase of 
$383,000 from the allowance as of December 31, 1996.   Net charge-offs to 
average loans were 0.27% in 1997.  The increase from prior periods is due 
primarily to consumer loans. The allowance to period end loans was 1.92% as 
of December 31, 1997.

     Management considers changes in the size and character of the loan 
portfolio, changes in non-performing and past due loans, historical loan loss 
experience, and the existing and prospective economic conditions when 
determining the adequacy of the allowance for loan losses. Although 
management believes that the allowance for loan losses is adequate to provide 
for both potential losses and estimated inherent losses in the portfolio, 
future provisions will be subject to continuing evaluations of the inherent 
risk in the portfolio and if the economy declines or asset quality 
deteriorates, material additional provisions could be required.

                                     -33-


     The following table provides a summary of the allocation of the 
allowance for loan losses for specific loan categories as of the dates 
indicated. The allocations presented should not be interpreted as an 
indication that charges to the allowance for loan losses will be incurred in 
these amounts or proportions, or that the portion of the allowance allocated 
to each loan category represents the total amount available for future losses 
that may occur within these categories. The unallocated portion of the

LIQUIDITY AND CASH FLOW

     The objective of liquidity management is to maintain the Company's 
ability to meet the day-to-day cash flow requirements of its customers who 
either wish to withdraw funds or require funds to meet their credit needs. 
The Company must manage its liquidity position to meet the needs of its 
customers, while maintaining an appropriate balance between assets and 
liabilities to meet the return on investment objectives of its stockholders. 
The Company monitors the sources and uses of funds on a daily basis to 
maintain an acceptable liquidity position, principally through deposit 
receipts and repayments; loan originations, extensions and repayments; and 
management of investment securities. 

     Net cash provided by operating activities, primarily representing net 
income, totaled $44 million for 1997, $29 million for 1996 and $28 million 
for 1995. Net cash used for investing activities totaled $155 million for 
1997, $105 million for 1996 and $79 million for 1995. The funds used for 
investing activities primarily represent increases in loans and investments 
in connection with acquisitions and internal growth for each year reported. 

     The primary financing activities of the Company are deposits, borrowings 
and capital. The Company's current liquidity position is also supported by 
the management of its investment portfolio, which provides a structured flow 
of maturing and reinvestable funds that could be converted to cash, should 
the need arise. Maturing balances in the Company's loan portfolio also 
provides options for cash flow management. The ability to redeploy these 
funds is an important source of immediate to long-term liquidity. Additional 
sources of liquidity include Federal funds lines, other borrowings and access 
to the capital markets. 

     As a holding company, FIBS is a corporation separate and apart from the 
Banks, and therefore, provides for its own liquidity. Substantially all of 
FIBS's revenues are obtained from management fees, dividends declared and 
paid by the Banks and net revenues of the data processing division. As of 
December 31, 1997, the Banks had approximately $16 million available to be 
paid as dividends to FIBS. There are statutory and regulatory provisions that 
could limit the ability of the Banks to pay dividends to FIBS. See Part I, 
Item 1, "Business-Regulation and Supervision." Management of FIBS believes 
that such restrictions will not have an impact on the ability of FIBS to meet 
its ongoing cash obligations. As of December 31, 1997, the Company did not 
have any material commitments for capital expenditures.

                                     -34-


     In connection with the acquisition of the FIB Banks, the Company 
obtained a revolving term loan and issued subordinated notes and shares of 
noncumulative perpetual preferred stock. The revolving term loan bears 
interest at variable rates (7.44% weighted average rate as of December 31, 
1997) and was issued by a syndicate of banks led by First Security Bank, N.A. 
The loan expires in December 2003, and is secured by all of the outstanding 
capital stock of the Banks. The available borrowing amount under the loan is 
reduced by $2 million on a semi-annual basis. The loan contains various 
restrictions dealing with, among other things, minimum capital ratios, the 
sale or issuance of capital stock and the maximum amount of dividends. As of 
December 31, 1997, the amount outstanding under the revolving term loan was 
$7 million, with an additional $19 million in borrowing capacity available 
thereunder. The subordinated notes are held by an institutional investor, 
bear interest at 7.5% per annum, are unsecured and mature in increasing 
annual payments during the period from October 2002 to October 2006. For 
additional information concerning the revolving term loan and the 
subordinated notes, see "Notes to Consolidated Financial Statements - Long 
Term Debt" included in Part IV, Item 14.

     The noncumulative perpetual preferred stock was redeemed on November 7, 
1997 with a portion of the proceeds from issuance of trust preferred 
securities by FIB Capital.  The trust preferred securities are unsecured, 
bear interest at a rate of 8.625%, and mature on December 1, 2027.  Interest 
distributions are payable quarterly, however, the Company may defer interest 
payments at any time for a period not exceeding 20 consecutive quarters.  The 
trust preferred securities may be redeemed prior to maturity at the Company's 
option on or after December 1, 2002 or at any time in the event of 
unfavorable changes in tax laws or regulations in an amount equal to their 
liquidation amount plus accumulated and unpaid distributions to the date of 
redemption.  The Company has guaranteed the payment of distributions and 
payments for redemption or liquidation of the trust preferred securities to 
the extent of funds held by FIB Capital.  The remaining proceeds from the 
issuance of trust preferred securities were used to reduce the Company's 
revolving term loan.  For additional information concerning the trust 
preferred securities see "Notes to Consolidated Financial Statements - 
Mandatorily Redeemable Preferred Securities of Subsidiary Trust" included in 
Part IV, Item 14.

CAPITAL RESOURCES

     Stockholders' equity decreased 0.3% to $146 million as of December 31, 
1997. This decrease resulted primarily from the redemption of $20 million of 
noncumulative perpetual preferred stock which was partially offset by an 
increase in retained earnings. Stockholders' equity increased 33.6% to $146 
million as of December 31, 1996 from $109 million as of December 31, 1995. 
This increase was due primarily to the issuance of the noncumulative 
perpetual preferred stock, together with retained earnings. Stockholders' 
equity is influenced primarily by earnings, dividends and, to a lesser 
extent, sales and redemptions of common stock involving employees of the 
Company. For the years ended December 31, 1997, 1996 and 1995, the Company 
paid aggregate cash dividends to stockholders of $9 million, $6 million and 
$4 million, respectively.

     Pursuant to FDICIA, the Federal Reserve and the FDIC have adopted 
regulations setting forth a five-tier system for measuring the capital 
adequacy of the financial institutions they supervise.  At December 31, 1997, 
each of the Banks had levels of capital which met or exceeded the 
well-capitalized guidelines. For additional information concerning the 
capital levels of the Company, see "Notes to Consolidated Financial 
Statements - Regulatory Matters" contained in Part IV, Item 14. 

INTEREST RATE RISK MANAGEMENT

     The Company's primary earnings source is the net interest margin, which 
is affected by changes in the level of interest rates, the relationship

and the mix of interest-bearing assets and liabilities.

     The ability to optimize the net interest margin is largely dependent 
upon the achievement of an interest rate spread which can be managed during 
fluctuations of interest rates.  Interest 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.  The following 
table shows interest rate sensitivity gaps for different intervals as of 
December 31, 1997:

     Assumptions used:

     (1)  Does not include nonaccrual loans of $9,681.

     (2)  Historical analysis shows that these deposit categories, while 
          technically subject to immediate withdrawal, actually display 
          sensitivity characteristics that generally fall within one and five 
          years.  The allocation presented is based on that historical 
          analysis.

     As noted in footnote 2 above, interest-bearing demand accounts and 
savings deposits are allocated based on historical analysis of their interest 
sensitivity characteristics although they are technically subject to 
immediate withdrawal.  If these deposits were included in the three month or 
less category, the above table would reflect a negative three month gap of 
$339 million, a negative cumulative one year gap of $305 million and a 
positive cumulative one to five year gap of $179 million.

                                     -36-


     The balance sheet structure is primarily short-term in nature with most 
assets and liabilities repricing or maturing in less than five years.  
Management monitors the sensitivity of net interest margin by utilizing 
income simulation models and traditional gap analysis.  The income simulation 
model involves a degree of estimation based on certain assumptions management 
believes to be reasonable including estimated cash flows, prepayments, 
repricing characteristics, actual maturities, deposit growth and retention, 
and the relative sensitivity of assets and liabilities to change in market 
interest rates.  The relative sensitivity is important to consider since the 
Company's deposit base is not subject to the same degree of interest 
sensitivity as its assets.  The Company attempts to maintain a mix of 
interest earning assets and deposits such that no more than 5% of the net 
interest margin will be at risk should interest rates vary one percent.  
However, there can be no assurance as to the actual effect changes in 
interest rates will have on the Company's net interest margin.

     In evaluating exposure to interest rate risk, management does not view 
the gap amounts in the following table as presenting an unusually high risk 
potential.  However, no assurances can be given that the Company is not at 
risk in the event of rate increases or decreases.

YEAR 2000

     In 1997, the Company completed the evaluation phase of its Year 2000 
project to ensure business is not interrupted by the change in the 
millennium.  The project calls for either system modification to, or 
replacement of, existing business system applications. Upon completion of the 
project, all systems including microsystems, payment systems, ATM software 
and mainframe systems, will be Year 2000 compliant.  The Company anticipates 
that substantially all of the remaining work under this project, including 
testing of critical systems, will be initially completed by the end of 1998.  
The cost of the Year 2000 project was not material to the Company's 1997 
earnings and is not expected to be material to the Company's 1998 earnings or 
thereafter.  Such costs will be expensed as incurred.  Unanticipated problems 
or difficulties, however, could significantly increase the Company's 
estimated expenditures for the Year 2000 project.

     The Company has provided its business customers, suppliers and vendors 
with information regarding the Company's progress on Year 2000 issues and has 
requested similar information in return.  The Company continues to bear some 
risk related to the Year 2000 issue and could be adversely affected if other 
entities not affiliated with the Company do not appropriately address their 
own Year 2000 compliance issues.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1996, the Financial Accounting Standards Board (the "FASB") 
issued SFAS No. 125, "Accounting for Transfers and Servicing of Financial 
Assets and Extinguishment of Liabilities." This statement provides accounting 
and reporting standards for transfers and servicing of financial assets and 
extinguishment of liabilities. The provisions of SFAS No. 125 apply to 
transactions occurring after December 31, 1996. This adoption has not had a 
material effect on the consolidated financial position or results of 
operations of the Company. 

     In February 1997, the FASB issued SFAS No. 128, "Earnings per Share." 
This statement simplifies the standards for computing earnings per share 
("EPS") and replaces the presentation of primary and fully diluted EPS with a 
presentation of basic and fully diluted EPS on the face of the income 
statement for all entities with complex capital structures. The provisions of 
SFAS No. 128 apply to financial statements issued for periods ending after 
December 15, 1997.  Adoption did not have a material effect on the reported 
EPS of the Company. 

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive 
Income," which establishes standards for reporting and displaying 
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. 
SFAS No. 130 is effective for fiscal years beginning after December 15, 1997. 
Reclassification of financial statements for earlier periods provided for 
comparative purposes is required. Management expects that adoption will not 
have a material effect on the consolidated financial position or results of 
operations of the Company.

                                     -37-


     In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments 
of an Enterprise and Related Information."  This statement requires public 
business enterprises to disclose selected information about operating 
segments including segment income, revenues and asset data.  Operating 
segments, as defined in SFAS No. 131, would include those components for 
which financial information is available and evaluated regularly by the chief 
operating decision maker in assessing performance and making resource 
allocation determinations for operating components such as those which 
contribute ten percent or more of combined revenue, income or assets.  SFAS 
No. 131 is effective for financial statements for periods beginning after 
December 31, 1997.  Management expects that adoption will not have a material 
impact on the Company's consolidated financial statements.

     ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The business of the Company and the composition of its balance sheet 
consists of investments in interest-earning assets (primarily loans and 
investment securities) which are primarily funded by interest-bearing 
liabilities (deposits and indebtedness). Such financial instruments have 
varying levels of sensitivity to changes in market interest rates.  Interest 
rate risk results when, due to different maturity dates and repricing 
intervals, interest rate indices for interest-earning assets decrease 
relative to interest-bearing liabilities, thereby creating a risk of 
decreased net earnings and cash flow.

     The following table provides information about the Company's market 
sensitive financial instruments, categorized by maturity and the instruments' 
fair values at December 31, 1997.  The table constitutes a "forward-looking 
statement."  The Company's major market risk exposure is changing interest 
rates.  For a description of the Company's policies with respect to managing 
risks associated with changing interest rates, see Part I, Item 7, 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operation-Financial Condition-Interest Rate Risk Management."

     Although the Company characterizes some of its interest-sensitive assets 
as securities available-for-sale, such securities are not purchased with a 
view to sell in the near term.  Rather, such securities may be sold in 
response to or in anticipation of changes in interest rates and resulting 
prepayment risk.  Thus, all interest-sensitive assets described below are 
non-trading.  See "Notes to Consolidated Financial Statements-Summary of 
Significant Accounting Policies" included in Part IV, Item 14.

           ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    The Company has had, and expects to have in the future, banking 
transactions in the ordinary course of business with related parties, 
including business with directors, officers, stockholders 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 
unrelated persons and that did not involve more than a normal risk of 
collectibility or present other unfavorable features.  To the extent that 
such transactions consisted of extensions of credit to Company executive 
officers and directors and to certain members of the Scott family, such 
extensions of credit were made in the ordinary course of business, were made 
on substantially the same terms, including interest rates and collateral on 
loans, as those prevailing at the same time for comparable transactions with 
unrelated persons and did not involve more than a normal risk of 
collectibility or present other unfavorable features. Loans to FIBS's 
executive officers, directors and their related interests represented 
approximately 7.0% of the Company's stockholders' equity as of December 31, 
1997. Loans to executive officers, directors and related interests of 
officers and directors of FIBS and the Banks represented approximately 10.5% 
of the Company's stockholders' equity as of December 31, 1997. 

     In July 1997, 78,072 shares of common stock were sold by the Company to 
certain officers, directors, director nominees and employees. The total cash 
price was $1.66 million. 

     In October 1997, 87,236 shares of common stock were sold by the Company 
to 403 individual participants in the Company's 401(k) Savings Plan. The 
total cash price was $2.05 million. 

     From time to time the Company repurchases shares of common stock from 
stockholders of the Company pursuant to stockholder repurchase agreements and 
otherwise at the then appraised value thereof. In addition, the Company may 
redeem shares of common stock from the Company's 401(k) Savings Plan on a 
quarterly basis in accordance with the investment elections of the plan's 
participants or in connection with distributions under the plan. For the year 
ended December 31, 1997, the Company redeemed shares of common stock from the 
Company's 401(k) Savings Plan in the amount of $137,437. 

     The Company is the anchor tenant in a commercial building in which the 
Company's principal executive offices are located in Billings, Montana. The 
building is owned by a joint venture partnership in which FIB Montana is one 
of the two partners, owning a 50% interest in the partnership. The other 50% 
interest in the partnership is owned by a company in which Joel Long, a 
director of the Company, owns beneficially an equity interest of 
approximately 33%. Indebtedness of the partnership ($10.4 million as of 
December 31, 1997) is recourse to the partners and guaranteed by the Company. 
The Company paid rent to the partnership of $814,000 in 1997.

KPMG Peat Marwick LLP



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

We have audited the accompanying consolidated balance sheets of First
Interstate BancSystem, Inc. and subsidiaries as of December 31, 1997 and
1996, 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, 1997.  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, Inc. and subsidiaries as of December 31, 1997 and
1996, and the results of their operations and their cash flows for each of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
(DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION.  The Company, through the branch offices of its banking 
     subsidiaries, provides a full range of banking services to individual 
     and corporate customers throughout the states of Montana and Wyoming.  
     The Company is subject to competition from other financial institutions 
     and financial service providers, and is also subject to the regulations 
     of various government agencies and undergoes periodic examinations by 
     those regulatory authorities.

     During 1997, the Company merged its six banking subsidiaries into two 
     resultant bank subsidiaries, First Interstate Bank in Montana and First 
     Interstate Bank in Wyoming.

     Effective October 7, 1997, First Interstate BancSystem of Montana, Inc. 
     changed its name to First Interstate BancSystem, Inc.

     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, Inc. (Parent 
     Company) and its operating subsidiaries: First Interstate Bank in 
     Montana ("FIB Montana"), First Interstate Bank in Wyoming ("FIB 
     Wyoming"), Commerce Financial, Inc. and FIB Capital Trust.  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, 1997 the Company was required to have aggregate reserves 
     in the form of cash on hand and deposits with the Federal Reserve Bank 
     of approximately $7,247.  Also, an additional $16,000 compensating 
     balance was maintained with the Federal Reserve Bank to mitigate the 
     payment of service charges for check clearing services.

     INVESTMENT SECURITIES.  Securities that the Company has the positive intent
     and ability to hold to maturity are classified as held-to-maturity and 
     carried at amortized cost.  Subordinated debentures that may be sold in 
     response to or in anticipation of changes in interest rates and 
     resulting prepayment risk, or other factors, and marketable equity 
     securities, are classified as available-for-sale and carried at fair 
     value.  The unrealized gains and losses on these securities are 
     reported, net of applicable taxes, as a separate component of 
     stockholders' equity.  Debt and equity securities that are purchased and 
     held principally for the purpose of selling them in the near term are 
     classified as trading account assets and reported at fair value. The 
     Company carried no trading account assets during 1997, 1996 or 1995.  
     Management determines the appropriate classification of securities at 
     the time of purchase and at each reporting date management reassesses 
     the appropriateness of the classification.

     The amortized cost of subordinated debentures 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 and prepaid interest, net of related 
     costs, are recognized over the expected 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.

     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.  Goodwill consists of the excess purchase price over the fair 
     value of net assets from acquisitions ("excess purchase price") and the 
     intangible value of depositor relationships resulting from deposit 
     liabilities assumed in acquisitions ("core deposit intangibles").  
     Excess purchase price is being amortized using the straight-line method 
     over periods of primarily 15 to 25 years.  Core deposit intangibles  are 
     amortized using an accelerated method based on an estimated runoff of 
     the related deposits, not exceeding 10 years.

     OTHER INTANGIBLES.  Purchased mortgage servicing rights ("MSR") 
     represent the value of purchased rights to service mortgage loans.  The 
     MSR are amortized 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.  MSR of $781 and $1,052 as of December 31, 
     1997 and 1996, respectively, are included in other assets.

     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 $5,964 in 1997, $4,182 in 1996 and $3,541 in 
     1995.

     LONG-LIVED ASSETS. Long-lived assets and certain identifiable 
     intangibles (e.g. premises, Goodwill, core deposit intangibles) are 
     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, if any, is based on the assets' fair value, which may 
     be estimated by discounting the expected future cash flows.  There were 
     no impairment losses recognized during 1997 or 1996.

     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.

     TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF 
     LIABILITIES.  In June 1996, the Financial Accounting Standards Board 
     issued Statement of Financial Accounting Standards ("SFAS") No. 125, 
     "Accounting for Transfers and Servicing of Financial Assets and 
     Extinguishments of Liabilities."  SFAS No. 125 is effective for 
     transfers and servicing of financial assets and extinguishments of 
     liabilities occurring after December 31, 1996 and is to be applied 
     prospectively.  This Statement provides accounting and reporting 
     standards for transfers and servicing of financial assets and 
     extinguishments of liabilities based on consistent application of a 
     financial-components approach that focuses on control.  It distinguishes 
     transfers of financial assets that are sales from transfers that are 
     secured borrowings.

     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 on market 
     quotes and are amortized in proportion to and over the period of 
     estimated net servicing income. Servicing rights are subsequently 
     evaluated for impairment by stratifying the servicing assets based on 
     risk characteristics including loan type, note rate, and loan term.

     Adoption of the statement did not have a material impact on the 
     financial condition or results of operations of the Company.  The 
     Company capitalized mortgage servicing rights of $238 on loans sold with 
     servicing retained in 1997. There were no impairment losses recognized 
     in 1997.

     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.  The Company adopted SFAS No. 128, "Earnings Per Share," 
     as of January 1, 1997.  SFAS No. 128 revises the manner in which 
     earnings per share (EPS) is calculated by replacing the presentation of 
     primary EPS and fully diluted EPS with a presentation of basic EPS and 
     diluted EPS.  All periods presented have been restated to conform with 
     SFAS No. 128.  The Company also adopted SFAS No. 129, "Disclosures of 
     Information About Capital Structure."  This statement was issued in 
     connection with SFAS No. 128 and lists required disclosures about 
     capital structure that had been included in a number of previously 
     existing separate statements and opinions.

     Basic earnings per common share is calculated by dividing net income 
     less preferred stock dividends by the weighted average number of common 
     shares outstanding during the period.  Diluted earnings per common share 
     is calculated by dividing net income less preferred stock dividends by 
     the weighted average number of common shares and potential common stock 
     outstanding during the period.  Book value per common share is 
     calculated by dividing total stockholders' equity less preferred stock 
     by the number of common shares outstanding at the end of the year.

     On October 7, 1997, the Company effected a four-for-one split of the 
     Parent Company's existing common stock.  All share and per share data 
     presented have been restated to give effect to the stock split.

     STOCK-BASED COMPENSATION.  The Company measures compensation costs for 
     stock-based employee compensation plans using the intrinsic value-based 
     method of accounting in accordance with Accounting Principles Board 
     No. 25.

     YEAR 2000.  In 1997, the Company established an overall plan to address 
     the Year 2000 issues as they affect financial reporting. Year 2000 
     issues involve the use of only two digits to identify a year in a date 
     field, potentially causing application failures or erroneous results at 
     the Year 2000.  Upon development of the overall plan, the Company began 
     modifying its computer systems to be Year 2000 compliant by the end of 
     1998.  Management does not expect costs related to the modification 
     project to be material. Such costs will be expensed as incurred.

     RECLASSIFICATIONS.  Certain reclassifications have been made to the 1996 
     and 1995 amounts to conform to the 1997 presentation.

(2)  REGULATORY MATTERS

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

     Quantitative measures established by regulation to ensure capital 
     adequacy require the Company to maintain minimum amounts and ratios of 
     total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital 
     to average assets, as defined in the regulations.  As of December 31, 
     1997, the Company exceeded all capital adequacy requirements to which is 
     was subject.

     As of December 31, 1997, the most recent notification from the Federal 
     Reserve Bank categorized the Company as well capitalized under the 
     regulatory framework for prompt corrective action.  To be categorized as 
     well capitalized the Company must maintain minimum total risk-based, 
     Tier 1 risk-based, and leverage ratios as set forth in the table.  There 
     are no conditions or events since that notification that management 
     believes have changed the institution's category.

     The Company's actual capital amounts and ratios as of December 31, 1997 
     and 1996 are presented in the following table:
     


                                                                                  Adequately                        Well

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


        (1)  Includes loans to agricultural customers secured by real estate of 
             $56,397 and $52,689 at December 31, 1997 and 1996, respectively.
     
        (2)  Includes loans secured by commercial real estate properties of 
             $264,842 and $198,570 at December 31, 1997 and 1996, respectively.
     
        (3)  Includes loans secured by second mortgages on real estate of
             $93,510 and $74,607 at December 31, 1997 and 1996, respectively.
     
     At December 31, 1997, 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 $9,681 and $6,822 at December 31, 1997 and 
     1996, respectively.  If interest on nonaccrual loans had been accrued, 
     such income would have approximated $763 and $405, respectively.  Loans 
     contractually past due ninety days or more aggregating $4,883 on 
     December 31, 1997 and $6,432 on December 31, 1996 were on accrual 
     status.  Such loans are deemed adequately secured and in the process of 
     collection.
      
     Included in the nonaccrual loans at December 31, 1997 and 1996 are 
     $1,909 and $5,122, respectively, of loans which are considered impaired. 
     Of this amount, an impairment allowance of $676 and $436, respectively, 
     is included in the Company's allowance for loan losses.  The average 
     recorded investment in impaired loans for the years ended December 31, 
     1997, 1996 and 1995 was approximately $7,580, $3,870 and $3,080, 
     respectively.  If interest on impaired loans had been accrued, the 
     amount of interest income on impaired loans during 1997, 1996 and 1995 
     would have been approximately $706, $357 and $283, respectively.

      1995, respectively.  At December 31, 1997, 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 
      states 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 $15,329 at December 
      31, 1997 and $12,174 at December 31, 1996 (including outstanding loans 
      of new executive officers and directors in 1997).  During 1997, new 
      loans and advances on existing loans of $11,613 were funded and 
      repayments totaled $8,458.  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, 1997. 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, 1997 and 1996 are 
      $2,621 and $2,540, respectively.  The net cash surrender value of 
      key-executive insurance policies included in other assets is $400 and 
      $278 at December 31, 1997 and 1996, respectively.

      During 1994, the Company provided insurance contracts for certain key 
      officers.  The net cash surrender value of these contracts is $1,525 
      and $1,365 at December 31, 1997 and 1996, 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.  The Company 
      currently accrues the earned portion of the post-employment benefit.

      Deposits are summarized as follows:

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

      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, 1997 management 
      continues to believe it is more likely than not that the Company will 
      realize the benefits of these deductible differences.

      The Company had current income taxes receivable of $286 at December 31, 
      1997 and current income taxes payable of $508 at December 31, 1996.

      The proceeds from issuance of the revolving term note, subordinated 
      notes and preferred stock (see note 15) were utilized to fund 
      acquisitions (see note 20).

      In connection with its borrowings, the Company has agreed to certain 
      restrictions dealing with, among other things, minimum capital ratios, 
      the sale or issuance of capital stock and the maximum amount of 
      dividends.

      The Company has a revolving term loan with its primary lender in the 
      amount of $6,700 at December 31, 1997.  The available borrowing amount 
      at December 31, 1997 of $19.3 million is reduced by $2,000 on a 
      semi-annual basis.  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 which varies 
      depending on the Company's capital ratios.  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 $135,000, subject to funds availability.  These lines are 
      subject to cancellation without notice.  The Company also has been 
      approved for participation in the Federal Home Loan Bank Cash 
      Management Advance Program for borrowings up to approximately $98,687.

(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 $1,022, 
      $839 and $685 in 1997, 1996 and 1995, 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 $1,030 in 1997, $814 in 
      1996 and $703 in 1995.

      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 $514 in 1997, $72 in 1996 and $170 in 1995.

      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 6.58%, 5.65% and 7.78% in 1997, 1996 
      and 1995, respectively; dividend yield of 4.03%, 2.50% and 2.67% in 
      1997, 1996 and 1995, respectively; and expected life of options of 10 
      years in 1997, 1996 and 1995.

      Pro forma disclosures, listed below, include options granted in 1997, 
      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, results of operations or liquidity.

      During 1997, the Company purchased a 50% ownership interest in a Cessna 
      aircraft.  The investment is accounted for using the equity method.  
      The Company is jointly and severally liable for aircraft indebtedness 
      of $1,259 as of December 31, 1997.  Usage charges and overhaul accruals 
      expensed in 1997 totaled $104.

      The Parent Company and the Billings office of First Interstate Bank 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 $10,405 at December 31, 1997 is 
      recourse to the partners.  Total rents paid to the partnership were 
      $814 in 1997 and 1996 and $711 in 1995.

      The Company also leases certain premises and equipment from third 
      parties under operating leases.  Total rental expense to third parties 
      was $1,204 in 1997, $1,019 in 1996 and $1,425 in 1995.

      The total future minimum rental commitments required under operating 
      leases that have initial or remaining noncancelable lease terms in

      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 and the franchise agreement 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.  Generally, all standby letters of credit 
      and commitments to extend credit are subject to annual renewal.  At 
      December 31, 1997, stand-by letters of credit in the amount of $20,692, 
      were outstanding.  Commitments to extend credit to existing and new 
      borrowers approximated $297,767 at December 31, 1997, which includes 
      $30,513 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 per share.  The holders of Preferred Stock 
      were entitled to receive dividends in cash at the rate of $85.30 per 
      share.  On November 7, 1997, the Preferred Stock was redeemed at a 
      price of $1,000 per share plus accrued but unpaid dividends of $178.  
      In conjunction with the redemption the Company recorded a $500 
      prepayment penalty.

      At December 31, 1997 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.

(16)  MANDATORILY REDEEMABLE PREFERRED SECURITIES OF SUBSIDIARY TRUST

      FIB Capital Trust ("Trust"), a wholly-owned statutory business trust, 
      was formed on October 1, 1997 with an initial capitalization of $1.2 
      million. The Trust was formed for the exclusive purpose of issuing 
      Capital Trust Preferred Securities ("trust preferred securities") and 
      using the proceeds to purchase Junior Subordinated Debentures 
      ("subordinated debentures") issued by the Company.  The sole assets of 
      the Trust are the subordinated debentures.

      On November 7, 1997, the Trust issued $40,000 of trust preferred 
      securities bearing a cumulative fixed interest rate of 8.625% and 
      maturing on December 1, 2027.  Interest distributions are payable 
      quarterly beginning December 31, 1997.  The trust preferred securities 
      are subject to mandatory redemption upon repayment of the subordinated 
      debentures at their stated maturity date or their earlier redemption in 
      an amount equal to their liquidation amount plus accumulated and unpaid 
      distributions to the date of redemption.  The Company guaranteed the 
      payment of distributions and payments for redemption or liquidation of 
      the trust preferred securities to the extent of funds held by the 
      Trust.  The obligations of the Company under the subordinated 
      debentures together with the guarantee and other back-up obligations, 
      in the aggregate, constitute a full and unconditional guarantee by the 
      Company of the obligations of the Trust under the trust preferred 
      securities.

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

      Also on November 7, 1997, the Company issued $41,237 in subordinated 
      debentures, the proceeds of which were used to redeem $20,000 of 
      Preferred Stock and paydown revolving term debt.

      The subordinated debentures are unsecured, bear interest at a rate of 
      8.625% per annum and mature on December 1, 2027.  Interest is payable 
      quarterly beginning December 31, 1997.  The Company may defer the 
      payment of interest at any time from time to time for a period not 
      exceeding 20 consecutive quarters provided that deferral period does 
      not extend past the stated maturity.  During any such deferral period, 
      distributions on the trust preferred securities will also be deferred 
      and the Company's ability to pay dividends on its common shares will be 
      restricted.

      Subject to approval by the Federal Reserve Bank, the trust preferred 
      securities may be redeemed prior to maturity at the Company's option on 
      or after December 1, 2002.  The trust preferred securities may also be 
      redeemed at any time in whole (but not in part) in the event of 
      unfavorable changes in laws or regulations that result in (1) FIB 
      Capital becoming subject to federal income tax on income received on 
      the subordinated debentures, (2) interest payable by FIBS on the 
      subordinated debentures becoming non-deductible for federal tax 
      purposes, (3) the requirement for FIB Capital to register under the 
      Investment Company Act of 1940, as amended, or (4) loss of the ability 
      to treat the trust preferred securities as "Tier 1 capital" under the 
      Federal Reserve capital adequacy guidelines.

      The trust preferred securities qualify as Tier 1 capital for regulatory 
      capital purposes.  Issuance costs consisting primarily of underwriting 
      discounts and professional fees of approximately $2,323 have been 
      capitalized and are being amortized through maturity to interest 
      expense using the straight-line method.

(18)  DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

      Fair value estimates are made at a specific point in time, based on 
      relevant market information and information about the financial 
      instrument.  These estimates do not reflect any premium or discount 
      that could result from offering for sale at one time 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.

      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.

            FINANCIAL ASSETS.  Due to the liquid and/or short-term nature of 
            cash, cash equivalents and interest-bearing deposits in bank, 
            carrying value of these instruments approximates market value.  
            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.  Fair value of fixed rate loans is calculated 
            by discounting scheduled cash flows adjusted for prepayment 
            estimates using discount rates based on secondary market sources, 
            if available, or based on estimated market discount rates that 
            reflect the credit and interest rate risk inherent in the loan 
            category.  The fair value of adjustable rate loans approximates 
            the carrying value of these instruments due to the frequent 
            repricing, provided there have been no changes in credit quality 
            since origination.

            FINANCIAL LIABILITIES AND TRUST SECURITIES.  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. The fair value of fixed-maturity 
            certificates of deposit is estimated using external market rates 
            currently offered for deposits with similar remaining maturities. 
            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.  The book value of the subordinated 
            notes approximates fair value estimated by discounting future 
            cash flows using current rates for advances with similar 
            characteristics. Fair value of the mandatorily redeemable 
            preferred securities of subsidiary trust is based on quoted 
            market price.

            COMMITMENTS TO EXTEND CREDIT AND STANDBY LETTERS OF CREDIT.  It 
            is not practicable to estimate the fair value of commitments to 
            extend credit because information necessary to support fair value 
            estimations is not readily available.

      A summary of the estimated fair values of financial instruments follows:

(20)  ACQUISITIONS AND EXPANSION

      FIRST CITIZENS BANK OF BOZEMAN.  On January 3, 1995, the Company 
      acquired all of the outstanding ownership of Citizens BancShares, Inc. 
      and its bank subsidiary, First Citizens Bank of Bozeman (collectively 
      "CBI").  The transaction was accounted for as a purchase and, 
      accordingly, the consolidated statement of income for the year ended 
      December 31, 1995 includes CBI's results of operations since the date 
      of the purchase.  CBI was merged with First Interstate Bank of Commerce 
      of Montana in 1995.

      FIRST NATIONAL PARK BANK.  On May 19, 1995, the Company acquired all of 
      the outstanding ownership of First Park County Bancshares, Inc. and its 
      bank subsidiary, First National Park Bank (collectively "FPCBI").  The 
      transaction was accounted for as a purchase and, accordingly, the 
      consolidated statement of income for the year ended December 31, 1995 
      includes FPCBI's results of operations since the date of the purchase. 
      FPCBI was merged with First Interstate Bank of Commerce of Montana in 
      1995.

      FIRST INTERSTATE BANK, FSB.  In November 1995, the Company filed an 
      application with the Office of Thrift Supervision for permission to 
      form a de novo savings bank in Hamilton, Montana.  Upon approval, the 
      Company capitalized the savings bank at $2,000 and opened the bank on 
      December 12, 1996.  Effective December 22, 1997, the savings bank was 
      combined with and became a branch of First Interstate Bank in Montana.

      FIRST INTERSTATE BANK OF MONTANA, N.A. AND FIRST INTERSTATE BANK OF 
      WYOMING, N.A.  On October 1, 1996, the Company acquired all of the 
      outstanding ownership of First Interstate Bank of Montana, N.A. 
      (FIBNA-MT) and First Interstate Bank of Wyoming, N.A. (FIBNA-WY).  The 
      transaction was accounted for as a purchase and, accordingly, the 
      consolidated statement of income for the year ended December 31, 1996 
      includes FIBNA-MT's and FIBNA-WY's results of operations since the date 
      of purchase.  During June 1997, FIBNA-MT merged with First Interstate 
      Bank in Montana and FIBNA-WY merged with First Interstate Bank in 
      Wyoming.

      MOUNTAIN BANK OF WHITEFISH.  On December 18, 1996, the Company acquired 
      all of the outstanding ownership of Mountain Bank of Whitefish 
      (FIB-Whitefish). The transaction was accounted for as a purchase and, 
      accordingly, the consolidated statement of income for the year ended 
      December 31, 1996 includes FIB-Whitefish's results of operations since 
      the date of purchase. During June 1997, FIB-Whitefish merged with First 
      Interstate Bank in Montana.

      MOUNTAIN FINANCIAL.  On February 5, 1997, First Interstate Bank in 
      Montana purchased the assets of Mountain Financial, a loan production 
      office in Eureka, Montana.  The total cash purchase price of the assets 
      aggregated $1,726, of which $166 was for premises and equipment and the 
      remaining $1,560 was for loans acquired.  Mountain Financial 
      subsequently became a branch of First Interstate Bank in Montana.

      During June 1997, the Company finalized its allocation of purchase 
      price related to the 1996 acquisitions of FIBNA-MT, FIBNA-WY and 
      FIB-Whitefish. Changes in preliminary estimates of the fair value of 
      loans, other assets and other liabilities resulted in a $3,572 decrease 
      in goodwill.
