                          RESTATEMENT EXPLANATORY NOTE

In 2000, the Company determined it was necessary to restate the Company's 2000,
1999, 1998 and 1997 consolidated quarterly financial statements to change the
accounting treatment for awards made pursuant to its Nonqualified Stock Option
and Stock Appreciation Rights Plan ("Stock Option Plan") from fixed to variable
plan accounting.

This Amendment No. 1 to the Company's Quarterly Report on Form 10-Q for the
quarterly period ended March 31, 1997 amends and restates the previously filed
Form 10-Q in its entirety. In order to preserve the nature and character of the
disclosures set forth in the Form 10-Q as originally filed, no attempt has been
made in this Amendment No. 1 to modify or update such disclosures except as
required to reflect the effects of the restatement and make nonsubstantial
revisions to the unaudited consolidated financial statements and the notes to
the unaudited consolidated financial statements. For additional information
regarding the restatement, see "Notes to Unaudited Consolidated Financial
Statements - Restatement" included in Part I, Item 1.

Share and per share data presented have not been restated to give effect of a
four-for-one stock split occurring during the fourth quarter of 1997.

              Notes to Unaudited Consolidated Financial Statements
                  (Dollars in thousands, except per share data)


(1)  Basis of Presentation

     In the opinion of management, the accompanying unaudited, restated
     consolidated financial statements contain all adjustments (all of which are
     of a normal recurring nature) necessary to present fairly the consolidated
     financial position at March 31, 1997 and December 31, 1996, and the results
     of consolidated operations and cash flows for each of the three month
     periods ended March 31, 1997 and 1996 in conformity with generally accepted
     accounting principles. The balance sheet information at December 31, 1996
     is derived from audited consolidated financial statements, however, certain
     reclassifications have been made to conform to the March 31, 1997
     presentation. For additional information regarding the restatement, see
     Note 10.

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

(2)  Cash and Cash Equivalents

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

(3)  Computation of Earnings Per Share

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

     On April 14, 1997, the Company paid a cash dividend on first quarter
     earnings of $0.98 per share to stockholders of record on that date. It has
     been the Company's practice to pay quarterly dividends based upon earnings.
     The April 1997 dividend represents 30% of the Company's net income for the
     quarter ended March 31, 1997 without taking into effect compensation
     expense related to stock options.

(7)  Acquisitions

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


(8)  Commitments and Contingencies

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

              Notes to Unaudited Consolidated Financial Statements
                  (Dollars in thousands, except per share data)


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

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

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

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

(9)  Accounting Pronouncements Not Yet Adopted

     In February 1997, the FASB issued SFAS No. 128, "Earnings per Share," which
     simplifies the standards for computing earnings per share ("EPS") by
     replacing the presentation of primary EPS with a presentation of basic EPS
     on the face of the income statement for all entities with complex capital
     structures. Basic EPS includes no dilution and is computed by dividing
     income available to common stockholders by the weighted average number of
     common chares outstanding for the period. Diluted EPS reflects the
     potential dilution of all securities that could share in the earnings of an
     entity. SFAS No. 128 replaces APB Opinion 15 and is effective for financial
     statements issued for periods ending after December 15,1997. The Company
     does not expect adoption of SFAS No. 128 to have an impact on its EPS
     disclosures.

     In February 1997, the FASB issued SFAS No. 129, "Disclosure of Information
     about Capital Structure," which lists required disclosures about capital
     structure that had been included in a number of previously existing
     separate statements and opinions. SFAS No. 129 is effective for financial
     statements for periods ending after December 15, 1997. The Company does not
     expect adoption of SFAS No. 129 to have a material impact on its capital
     structure disclosures.

(10) Restatement

     In 2000, the Company determined that fixed plan accounting treatment
     historically afforded its Stock Option Plan was not consistent with certain
     elements of the Stock Option Plan's operations and accounting guidance
     contained in APB Opinion 25 and related interpretations. Accordingly, the
     Company has restated the accompanying unaudited 1997 consolidated financial
     statements to reflect variable plan accounting treatment for awards made
     pursuant to its Stock Option Plan.

     The following is a summary of the effect of such restatement on the
     Company's consolidated financial statements:

     expense of $1,000 and a reduction in tax expense of $394 related to periods
     prior to 1997. The impact on 1997 net income and earnings per share is a
     decrease to net income of $606 and a decrease of $0.32 to earnings per
     share.

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

                             (Dollars in thousands)



(1)  MATERIAL CHANGES IN FINANCIAL CONDITION. Comparison of balance sheet items
     at March 31, 1997 and December 31, 1996.

     General. During the three month period ending March 31, 1997, total assets
     decreased slightly from $2,063,837 at December 31, 1996 to $2,061,502 at
     March 31, 1997. While total assets reflect only a nominal change, there
     were some notable shifts in the mix of assets and liabilities between
     periods. Seasonal declines in deposits and increases in loans and federal
     funds sold were funded with available cash, proceeds from maturities and
     paydowns of investments transactions, and other borrowings.

     Loans. Net loans increased $25,593 or 1.9% during the first three months of
     1997 from $1,347,682 at December 31, 1996 to $1,373,275 at March 31, 1997.
     The Company experienced increased loan volumes attributed to continued
     strong economic conditions in the communities served by the Company's
     banking subsidiaries, as well as some seasonal increases, particularly in
     agricultural lending, following traditional paydowns in the fourth quarter.

     Deposits. Total deposits decreased from $1,679,424 at December 31, 1996 to
     $1,649,456 at March 31, 1997. The decrease in deposits is principally
     related to an expected seasonal cycle in overall deposit growth that has
     historically occurred during the first half of the year. While non-interest
     bearing deposits declined $43,950 or 11.4% from December 31, 1996 to March
     31, 1997, modest growth in interest bearing deposits offset a portion of
     the decrease. Interest bearing deposits increased $13,982 or 1.1% from
     $1,294,053 at December 31, 1996 to $1,308,035 at March 31, 1997.

     Federal Funds Sold. Federal funds sold balances increased $22,750 to
     $27,695 at March 31, 1997 from $4,945 at December 31, 1996 as the Company's
     banking subsidiaries funded the cash requirements of correspondent banks
     facing similar seasonal fluctuations in customer deposits.

     Accounts Payable and Accrued Expenses. Accounts payable and accrued
     expenses increased $8,265 from $18,027 at December 31, 1996 to $26,292 at
     March 31, 1997. Approximately $855 of the increase resulted from the
     accrual of compensation expense related to outstanding stock options. The
     remaining increase is due primarily to the timing of federal and state
     income tax payments.

     Other Balance Sheet Accounts. Cash, amounts due from banks, interest
     bearing deposits and investment securities decreased $52,361 (in aggregate)
     and federal funds purchased, securities sold under repurchase agreements
     and other borrowed funds increased $11,280 (in aggregate) during the first
     quarter. These changes provided additional liquidity to fund increases in
     other earning assets, primarily loans and federal funds sold for one day
     periods.


(2)  MATERIAL CHANGES IN RESULTS OF OPERATIONS. Comparison of three months ended
     March 31, 1997 and March 31, 1996.

     General. On October 1, 1996, the Company acquired all of the outstanding
     capital stock of First Interstate Bank of Montana, N.A. and First
     Interstate Bank of Wyoming, N.A. and, on December 18, 1996, acquired all of
     the outstanding capital stock of Mountain Bank of Whitefish. The
     acquisitions were accounted for using the purchase method of accounting.
     Accordingly, the large increases in revenue and expenses for the three
     month period ended March 31,1997 compared to the three month period ended
     March 31, 1996 are due, in a large part, to the acquisitions. The increases
     in consolidated earnings resulting from the acquisitions are partially
     offset by higher interest expense resulting from funding of the
     acquisition.

     As a percentage of consolidated averages for the quarter ended March 31,
     1997, average interest earning assets and average interest bearing
     liabilities of the banks acquired were approximately 31% and 32%,
     respectively. Accordingly, there are material increases in most categories
     of income and expense for the three month period ended March 31,1997 when
     compared to the three months ended March 31, 1996. Significant variances
     not directly attributable to the acquired banks are explained in the
     discussions that follow.

     Net Income. Net income increased from $5,236 to $5,757 for the three month
     periods ended March 31, 1996 and 1997, respectively, an increase of $521.
     While net earnings of the acquired banks aggregated approximately $1,935
     for the quarter ended March 31, 1997, the increases were partially offset
     by additional interest expense and other indirect costs at the parent
     company.

     Interest Income. Interest income increased from $26,271 for the three month
     period ended March 31, 1996 to $39,161 for the three month period ended
     March 31, 1997. Adjusted for interest income of the acquired banks,
     interest income increased approximately $892 or 3.4% primarily due to
     internal growth in loan volume. One of the Company's primary objectives is
     to maintain steady growth in interest income by utilizing systems,
     procedures, and products designed to manage and promote balance sheet
     growth, maintain strong interest margins and provide competitive pricing.

     Interest Expense. Interest expense increased from $11,374 to $16,392 for
     the three month periods ended March 31,1996 and 1997, respectively, an
     increase of $5,018. Interest expense of the acquired banks and additional
     interest costs to fund the acquisitions aggregated approximately $4,600 in
     1997. The remaining increase was principally the result of internal growth
     in deposits.

     Adjusted for acquisitions, average interest-bearing deposits for the first
     quarter of 1997 were up $50,512 or 5.8% compared to averages for the first
     three months of 1996.

     Provision for Loan Losses. The provision for loan losses increased to
     $1,223 from $491 for the first quarter of 1997 and 1996, respectively.
     Increases in the provision of $566 are directly attributable to the
     acquisitions. The remaining increases are associated with growth in loan
     volumes and a slight deterioration in agricultural and consumer loans.
     Management actively monitors the local economies for strengths and
     diversity and unemployment levels, and evaluates its banking markets for
     their effects on its loan portfolio. Although nonperforming and problem
     assets have shown some increase, the fundamental economies within the
     Company's markets have remained strong. Overall, the increases in the
     provision for loan loss are reflective of management's evaluation of the
     risks inherent in the loan portfolio and current economic conditions.
     Should a significant shift in economic trends and/or increased volumes of
     problem credits or charge-offs occur, such events would likely require
     increased loan loss provisions in the future.

     Non-Interest Income. Overall, non-interest income increased $1,080 from
     $5,545 to $6,625 for the three month periods ended March 31, 1996 and 1997,
     respectively. Exclusive of non-interest income of $1,369 attributable to
     the acquisitions, non-interest income declined $289 or 5.2% in 1997.
     Decreases in income from fiduciary activities ($139) and data processing
     revenues ($300) as a result of non-recurring accrual adjustments made in
     January 1996 were partially offset by increases in data processing income
     resulting from increases in the number of customers and in the volume of
     transactions processed.

     Non-Interest Expenses. Non-interest expenses were $18,866 and $11,432 for
     the three month periods ended March 31, 1997 and 1996, respectively, an
     increase of $7,434. Non-interest expenses incurred directly by the acquired
     banks aggregated approximately $4,570, however, there were also other
     indirect increases in non-interest expenses related to the acquisitions
     recorded by the parent company and other bank subsidiaries particularly in
     the data division of the parent company and operations divisions of other
     banking subsidiaries. In addition, during the first quarter of 1997, the
     Company recorded compensation expense related to stock options of $1,000
     for periods prior to 1997 as a result of restating the financial statements
     to reflect variable plan accounting for awards made pursuant to the
     Company's stock option plan. For additional information regarding the
     restatement, see "Restatement Explanatory Note" included in Part I and
     "Notes to Unaudited Consolidated Financial Statements-Restatement" included
     in Part I, Item 1.

     Salaries and benefits expense increased $3,879 from $6,267 to $10,146 for
     the three month periods ended March 31, 1996 and 1997, respectively. Of the
     increase, $2,090 is the direct result of personnel costs related to
     employees of the acquired banks. In addition, during the first quarter of
     1997, the Company recorded compensation expense of $1,000 for periods prior
     to 1997 as a result of the restatement discussed above. Approximately $163
     of the remaining increase relates to the March 31, 1997 remeasurement of
     compensation expense related to outstanding stock options. The remaining
     increase of approximately $626, or 10.0%, is primarily due to increases in
     staffing levels, particularly in the Company's operations center and data
     division, necessary to support the Company's growth and inflationary
     increases.

     Occupancy, furniture and equipment expenses were $2,329 and $3,419 for the
     three months ended March 31, 1996 and 1997, respectively. Increases of
     approximately $399 or 17.1% not directly related to acquisitions are
     primarily due to increased depreciation on data processing equipment
     upgrades, and the continuing upgrades and expansion of the Company's micro
     computer and ATM networks.

     Other operating expenses were $5,384 and $2,923 for the three months ended
     March 31, 1997 and 1996, respectively. Exclusive of increases directly
     related to the acquired banks, other operating expenses increased
     approximately $779 or 26.7%. Major components of the increase include
     additional professional fees primarily due to revision and upgrade of the
     Company's job evaluation system aggregating approximately $167, increases
     in employee retirement accruals of approximately $70, increases in employee
     education costs of approximately $75, and increases in charitable
     contributions of approximately $127. Postage, supplies, and telephone
     expenses also increased approximately $313 primarily due to additional
     costs associated with growth in customer base.

     A decrease in royalty fee expense of $89 resulting from termination of the
     Company's franchise agreement with First Interstate Bancorp in May 1996
     partially offset increases in other operating expenses.

     Other variances in non-interest expenses for the first quarter of 1997 as
     compared to the first quarter of 1996 are not individually significant.
