3)    Ratios

      Returns on average assets and average equity were calculated based on
      daily averages.

4)    Dividends Declared

      On April 26, 2005, the Board of Directors declared a five-for-four stock
      split payable May 26, 2005 to shareholders of record on May 10, 2005, and
      all share and per share amounts have been restated to reflect the effects
      of the stock split. On March 11, 2005, the Board of Directors declared a
      $.14 per share quarterly cash dividend payable on April 21, 2005 to
      stockholders of record on April 12, 2005.

5)    Computation of Earnings Per Share

      Basic earnings per common share is computed by dividing net earnings by
      the weighted average number of shares of common stock outstanding during
      the period presented. Diluted earnings per share is computed by including
      the net increase in shares if dilutive outstanding stock options were
      exercised, using the treasury stock method.

      The following schedule contains the data used in the calculation of basic
      and diluted earnings per share:

6)    Stock Based Compensation

      The exercise price of all options granted has been equal to the fair
      market value of the underlying stock at the date of grant and,
      accordingly, no compensation cost has been recognized for stock options in
      the financial statements. Had the company determined compensation cost
      based on the fair value of the option itself at the grant date for its
      stock options and earnings per share under FASB Statement 123, Accounting
      for Stock-Based Compensation, the Company's net income would have been
      reduced to the pro forma amounts indicated below:

      In December, 2004, FASB Statement 123R was issued, which supersedes and
      replaces FASB Statement 123. FASB 123R requires recognition of
      compensation cost related to share-based payment plans to be recognized in
      the financial statements based on the fair value of the equity or
      liability instruments issued. The Company will adopt the statement at the
      earliest required adoption date.

      interest income, are shown in the following table on the basis of the
      amount of any increases (or decreases) attributable to changes in the
      dollar levels of the Company's interest-earning assets and
      interest-bearing liabilities ("Volume") and the yields earned and rates
      paid on such assets and liabilities ("Rate"). The change in interest
      income and interest expense attributable to changes in both volume and
      rates has been allocated proportionately to the change due to volume and
      the change due to rate.

      On February, 28, 2005 the Company completed the acquisition of First
      National Bank - West, Evanston, Wyoming, ("FNB") with total assets of $241
      million, loans of $90 million, and deposits of $225 million. This bank has
      seven locations in western Wyoming and became the eighth subsidiary bank
      of the Company and the first to be located in the state of Wyoming. A
      portion of the purchase price was allocated to core deposit intangible of
      $2,446,000 and goodwill of $22,813,000.

      The acquisition of Citizens Bank Holding Company and its subsidiary bank
      Citizens Community Bank, Pocatello, Idaho, with assets of approximately
      $115 million, was completed after the close of business on March 31, 2005.
      This bank operates from three banking offices in Pocatello and Idaho
      Falls, and a loan production office in Rexburg, Idaho. As of April 1, 2005
      this bank became the ninth subsidiary bank of the Company.

      Mountain West Bank of Coeur d'Alene entered into a purchase and sale
      agreement with Zions First National Bank to acquire the Zions branch in

      Subject to regulatory approval the transaction is expected to close on May
      20, 2005.

      Acquisitions are accounted for under the purchase method of accounting.
      Accordingly, the assets and liabilities of acquired branches and banks are
      recorded by the Company at their respective fair values at the date of the
      acquisition and the results of operations are included with those of the
      Company from the date of acquisition forward. The excess of the Company's
      purchase price over the net fair value of the assets acquired and
      liabilities assumed, including identifiable intangible assets, is recorded
      as goodwill.

At March 31, 2005 total assets were $3.306 billion, which is $477 million
greater than the March 31, 2004 assets of $2.829 billion, an increase of 17
percent, and $296 million greater than the December 31, 2004 balance, an
increase of 10 percent. Asset growth without FNB was $246 million, or 9 percent
over the prior year.

Total loans have increased $419 million from March 31, 2004, an increase of 28
percent, with the growth occurring in all loan categories. Commercial loans
increased $214 million, or 25 percent, real estate loans gained $118 million, or
37 percent, and consumer loans grew by $87 million, or 29 percent. Without the
FNB additions, loans increased $329 million from a year ago, a 22 percent
increase. Loan volume continues to be very strong with loans increasing $91
million, without the FNB acquisition, during the first quarter, which has
historically been a slow quarter for loan growth. During the same quarter last
year loans increased by $36 million.

Investment securities, including interest bearing deposits in other financial
institutions, and federal funds sold, have decreased $14 million from March 31,
2004. Without the addition of FNB, investments would have declined $110 million
from March 31, 2004. Cash flow from investment maturities, principal reductions,
and proceeds from sale of securities is now being used to fund the significant
growth in loans. Without the FNB additions, investments have decreased $24
million since December 31, 2004.

The Company typically sells a majority of long-term mortgage loans originated,
retaining servicing only on loans sold to certain lenders. The sale of loans in
the secondary mortgage market reduces the Company's risk of holding long-term,
fixed rate loans in the loan portfolio. Mortgage loans sold for the three months
ended March 31, 2005 and 2004 were $59 million and $67 million, respectively.
The Company has also been active in generating commercial SBA loans. A portion
of some of those loans is sold to other investors. The amount of loans sold and
serviced for others at March 31, 2005 was approximately $196 million.

Non-interest bearing deposits have increased $162 million, or 44 percent, since
March 31, 2004 and $292 million, or 11 percent, since December 31, 2004. Without
the FNB additions, the increase was $109 million, or 30 percent, since March 31,
2004. This continues to be a primary focus of our banks and the programs we have
initiated this past year continue to gain momentum. Total deposits have
increased $385 million from March 31, 2004, or 24 percent. Without the FNB
deposits, the increase was $163 million. This growth in deposits, a low cost
stable funding source, gives us increased flexibility in managing our asset mix.
Federal Home Loan Bank advances increased $57 million and repurchase agreements
and other borrowed funds increased $16 million from March 31, 2004 as we
continue to take advantage of these cost effective and flexible funding sources.

Liquidity and Capital Resources

The objective of liquidity management is to maintain cash flows adequate to meet
current and future needs for credit demand, deposit withdrawals, maturing
liabilities and corporate operating expenses. The principal source of the
Company's cash revenues is the dividends received from the Company's banking
subsidiaries. The payment of dividends is subject to government regulation, in
that regulatory authorities may prohibit banks and bank holding companies from
paying dividends which would constitute an unsafe or unsound banking practice.
The subsidiaries source of funds is generated by deposits, principal and
interest payments on loans, sale of loans and securities, short and long-term
borrowings, and net income. In addition, seven of the eight banking subsidiaries
are members of the FHLB. As of March 31, 2005, the Company had $1.136 billion of
available FHLB line of which $859 million was utilized. Accordingly, management
of the Company has a wide range of versatility in managing the liquidity and
asset/liability mix for each individual institution as well as the Company as a
whole. During the first quarter of 2005, all eight financial institutions
maintained liquidity and regulatory capital levels in excess of regulatory
requirements and operational needs.

In the normal course of business, there are various outstanding commitments to
extend credit, such as letters of credit and un-advanced loan commitments, which
are not reflected in the accompanying condensed consolidated financial

2004 and $6 million from year end 2004. The decline is primarily a function of
interest rate changes.

Allowance for Loan Loss and Non-Performing Assets

Non-performing assets as a percentage of total assets at March 31, 2005 were at
..27 percent, a decrease from .42 percent at March 31, 2004 and .32 percent at
December 31, 2004. This compares favorably to the Federal Reserve Bank Peer
Group average of .45 percent at December 31, 2004, the most recent information
available. The allowance for loan losses was 325 percent of non-performing
assets at March 31, 2005, compared to 211 percent a year ago. The allowance,
without the addition of FNB, has increased $3.184 million, or 13 percent, from a
year ago. Including FNB the increase is $5.232 million, or 21 percent. The
allowance of $29.801 million, is 1.56 percent of March 31, 2005 total loans
outstanding, down slightly from the 1.65 percent a year ago. The first quarter
provision for loan losses expense was $1.490 million, an increase of $660
thousand from the same quarter in 2004. The additional expense relates to the
growth in loans and the inherent risk associated with the size and risk
characteristics of loans originated over the past twelve months.

RESULTS OF OPERATIONS - THE THREE MONTHS ENDED MARCH 31, 2005 COMPARED TO THE
THREE MONTHS ENDED MARCH 31, 2004.

First National Bank-West was acquired on February 28, 2005 and became the
Company's eight subsidiary. The Ione, Washington branch was acquired by Mountain
West on June 4, 2004. Accordingly, results of operations and financial condition
for the acquisitions are included from the acquisition dates forward.

The Company reported net quarterly earnings of $11.520 million, an increase of
$.9 million, or 9 percent, over the $10.610 million for the first quarter of
2004. Diluted earnings per share for the quarter of $.37, is an increase of 9
percent over the per share earnings of $.34 for the same quarter of 2004. Return
on average assets and return on average equity for the quarter were 1.50 percent
and 17.06 percent, respectively, which compares with prior year returns for the
first quarter of 1.55 percent and 17.28 percent.

Net Interest Income

Net interest income for the quarter increased $2.067 million, or 8 percent, over
the same period in 2004, and $616 thousand from the fourth quarter of 2004.
Total interest income increased $5.042 million, or 14 percent, while total
interest expense was $2.975 million, or 33 percent higher. The increase in
interest expense is primarily attributable to the increase in the subordinated
debentures issued in March 2004 for the trust preferred securities, the
increased level of FHLB advances and other borrowings, and increases in short
term interest rates during 2004 and 2005. The Federal Reserve Bank has increased
targeted fed funds rates seven times, 175 basis points, in the last twelve
months. The net interest margin as a percentage of earning assets, on a tax
equivalent basis, was 4.08 percent which was below the 4.29 percent result for
the first quarter of 2004. The margin for the first quarter decreased from the
4.16 percent experienced for the fourth quarter of 2004. The interest margin for
FNB is approximately 20 basis points lower than the average of the other seven
banks which lowered the ratio. Also having a negative impact on the first
quarter interest margin was the reduction of FHLB dividends for the 2005
quarter. Dividends received were $255 thousand less than the same quarter last
year.

Non-interest Income

Fee income increased $1.390 million, or 27 percent, over the same period last
year, driven primarily by an increased number of loan and deposit accounts and
additional customer services offered. Gain on sale of loans increased $321
thousand from the first quarter of last year. Loan origination activity for
housing construction and purchases remains strong in our markets and has offset
much of the reduction in refinance activity experienced last year.

Non-interest Expense

Non-interest expense increased by $1.648 million, or 9 percent, from the same
quarter of 2004. Compensation and benefit expense increased $1.138 million, or
12 percent from the first quarter of 2004, with additional bank branches, normal
compensation increases for job performance and increased cost for benefits
accounting for the majority of the increase. The number of full-time-equivalent
employees has increased from 832 to 952, a 14 percent increase, since March 31,
2004. Occupancy and equipment expense increased $224 thousand, or 9 percent,
reflecting the cost of the additional locations and facility upgrades. Other
expenses increased $478 thousand, or 11 percent, primarily from audit costs from
compliance with Sarbanes-Oxley rules, additional marketing expenses, and costs
associated with new branch offices. The efficiency ratio (non-interest
expense/net interest income + non-interest income) was 51 percent for the 2005
quarter, which is an improvement from the 52 percent for the 2004 quarter.

Critical Accounting Policies

Companies apply certain critical accounting policies requiring management to
make subjective or complex judgments, often as a result of the need to estimate
the effect of matters that are inherently uncertain. The Company considers its
only critical accounting policy to be the allowance for loan losses. The
allowance for loan losses is established through a provision for loan losses
charged against earnings. The balance of allowance for loan loss is maintained
at the amount management believes will be adequate to absorb known and inherent
losses in the loan portfolio. The appropriate balance of allowance for loan
losses is determined by applying estimated loss factors to the credit exposure
from outstanding loans. Estimated loss factors are based on subjective
measurements including management's assessment of the internal risk
classifications, changes in the nature of the loan portfolio, industry
concentrations and the impact of current local, regional and national economic
factors on the quality of the loan portfolio. Changes in these estimates and
assumptions are reasonably possible and may have a material impact on the
Company's consolidated financial statements, results of operations and
liquidity.

Effect of inflation and changing prices

Generally accepted accounting principles require the measurement of financial
position and operating results in terms of historical dollars, without
consideration for change in relative purchasing power over time due to
inflation. Virtually all assets of a financial institution are monetary in
nature; therefore, interest rates generally have a more significant impact on a
company's performance than does the effect of inflation.

Forward Looking Statements

This Form 10-Q includes forward looking statements, which describe management's
expectations regarding future events and developments such as future operating
results, growth in loans and deposits, continued success of the Company's style
of banking and the strength of the local economies in which it operates. Future
events are difficult to predict, and the expectations described above are
necessarily subject to risk and uncertainty that may cause actual results to
differ materially and adversely. In addition to discussions about risks and
uncertainties set forth from time to time in the Company's public filings,
factors that may cause actual


                                       24


results to differ materially from those contemplated by such forward looking
statements include, among others, the following possibilities: (1) local,
national and international economic conditions are less favorable than expected
or have a more direct and pronounced effect on the Company than expected and
adversely affect the company's ability to continue its internal growth at
historical rates and maintain the quality of its earning assets; (2) changes in
interest rates reduce interest margins more than expected and negatively affect
funding sources; (3) projected business increases following strategic expansion
or opening or acquiring new banks and/or branches are lower than expected; (4)
costs or difficulties related to the integration of acquisitions are greater
than expected; (5) competitive pressure among financial institutions increases
significantly; (6) legislation or regulatory requirements or changes adversely
affect the businesses in which the Company is engaged.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company believes that there have not been any material changes in
information about the Company's market risk that was provided in the Form 10-K
report for the year ended December 31, 2004.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company's Chief Executive Officer and Chief Financial Officer have reviewed
and evaluated the effectiveness of our disclosure controls and procedures (as
required by Exchange Act Rules 240.13a-15(b) and 15d-14(c)) as of the date of
this quarterly report. Based on that evaluation, the Chief Executive Officer and
Chief Financial Officer have concluded that the Company's current disclosure
controls and procedures are effective and timely, providing them with material
information relating to the Company required to be disclosed in the reports we
file or submit under the Exchange Act.
