3)   Ratios

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

4)   Dividends Declared

     On September 27, 2006, the Board of Directors declared a $.17 per share
     quarterly cash dividend payable on October 19, 2006 to stockholders of
     record on October 10, 2006.

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 as 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:

     There were approximately 538,433 and 197,209 average shares excluded from
     the nine months ended diluted share calculation as of September 30, 2006,
     and 2005, respectively, due to the option exercise price exceeding the
     market price.

6)   Stock Based Compensation

     The Company has three stock based compensation plans outstanding. The
     Directors 1994 Stock Option Plan was approved to provide for the grant of
     options to outside Directors of the Company. The Employees 1995 Stock
     Option Plan was approved to provide the grant of options to certain
     full-time employees of the Company. The Employees 1995 Stock Option Plan
     expired in April 2005 and has granted but unexpired options outstanding.
     The 2005 Stock Incentive Plan was approved by shareholders on April 27,
     2005 which provides awards to certain full-time employees of the Company.
     The 2005 Stock Incentive Plan permits the granting of options, share
     appreciation rights, restricted shares, restricted share units, and
     unrestricted shares, deferred share units, and performance awards. Upon
     exercise of the stock options the shares are obtained from the authorized
     and unissued stock.

     The Company adopted SFAS No. 123 (Revised) Share-Based Payment, as of
     January 1, 2006 and, accordingly, has determined compensation cost based on
     the fair value of the option at the grant date. The Company adopted the
     modified prospective transition method in reporting financial statement
     results in the current and for future reporting periods. Under the modified
     prospective method, SFAS No. 123 (Revised) applies to new awards and to
     awards modified, repurchased, or cancelled after the effective date;
     accordingly the prior interim and annual periods do not reflect restated
     amounts. Additionally, the compensation cost for the portion of awards
     outstanding for which the requisite service has not been rendered that are
     outstanding as of the required effective date are recognized as the
     requisite service is rendered on or after the required effective date. For
     the nine months ended September 30, 2006, the compensation cost for the
     stock option plans was $2,410,000, with a corresponding income tax benefit
     of $707,000, resulting in a net earnings and cash flow from operations
     reduction of $1,703,000, or a decrease of $.05 per share for both basic and
     diluted earnings per share. For the three months ended September 30, 2006,
     the compensation cost for the stock option plans was $726,000, with a
     corresponding income tax benefit of $207,000, resulting in a net earnings
     and cash flow from operations reduction of $519,000, or a decrease of $.02
     per share for both basic and diluted earnings per share. Additionally, in
     the cash flow statement, the excess tax benefit from stock options
     decreased the net cash provided from operating activities and increased the
     net cash provided by financing activities by $990,000 and $319,000 for the
     nine and three months ended September 30, 2006,


                                       9



     respectively. Total unrecognized compensation cost, net of income tax
     benefit, related to non-vested awards which are expected to be recognized
     over the next weighted period of 1 year was $1,570,000 as of September 30,
     2006. The total fair value of shares vested during the nine months ended
     September 30, 2006 and 2005 was $1,245,000 and $920,000, respectively. The
     total fair value of shares vested during the three months ended September
     30, 2006 and 2005 was $709,000 and $368,000, respectively.

     Prior to the adoption of SFAS No. 123 (Revised), the Company utilized the
     intrinsic value method and compensation cost was the excess of the market
     price of the stock at the grant date over the amount an employee must pay
     to acquire the stock. The exercise price of all stock options granted has
     been equal to the fair market value of the underlying stock at the date of
     grant and, accordingly, the intrinsic value has been $0 and no compensation
     cost was recognized prior to the adoption of SFAS No. 123 (Revised). The
     Company did not modify any outstanding options prior to the adoption of the
     standard. If the Company had determined compensation cost based on fair
     value of the options at the grant date under SFAS 123 (Revised) prior to
     the date of adoption, the Company's net income would have been reduced to
     the pro forma amounts indicated below:

     The per share weighted-average fair value of stock options granted during
     2006 and 2005 was $6.47 and $3.52, respectively, on the date of grant using
     the Black Scholes option-pricing model with the following assumptions: 2006
     -- expected dividend yield 2.23%, risk-free interest rate of 4.35%,
     volatility ratio of 27%, and expected life of 3.3 years: 2005 - expected
     dividend yield 2.23%, risk-free interest rate of 3.44%, volatility ratio of
     18%, and expected life of 3.4 years. Expected volatilities are based on
     historical volatility and other factors. The Company uses historical data
     to estimate option exercise and termination with the valuation model.
     Employee and director awards, which have dissimilar historical exercise
     behavior, are considered separately for valuation purposes. The risk-free
     rate for periods within the contractual life of the option is based on the
     U.S. Treasury yield in effect at the time of the grant. The option awards
     generally vest upon six month or two years of service for directors and
     employees, respectively, and generally expire in five years.

15)  Rate/Volume Analysis

     Net interest income can be evaluated from the perspective of relative
     dollars of change in each period. Interest income and interest expense,
     which are the components of net 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.

17)  Recent Acquisitions

     On September 1, 2006, the Company completed the acquisition of First
     National Bank of Morgan with total assets of $89 million, loans of $41
     million, and deposits of $67 million. The bank is a national banking
     association with its main office in Morgan, Utah and one branch office in
     Mountain Green, Utah. First National Bank of Morgan became the Company's
     tenth subsidiary bank and the first whole-bank acquisition in Utah,
     expanding Glacier's focused community bank strategy in Utah and
     complementing its two existing Utah branches. A portion of the purchase
     price was allocated to core deposit intangible of $896,000 and goodwill of
     $10,715,000.

     On October 1, 2006, the acquisition of Citizens Development Company was
     completed. Citizens Development Company is a Billings, Montana-based bank
     holding company that owns five community banks located throughout Montana,
     with principal banking offices in Billings, Lewistown, Hamilton, Columbia
     Falls and Chinook. At September 30, 2006, Citizens had total assets of $411
     million, net loans of $308 million, total deposits of $361 million, and
     stockholders' equity of $37 million. A portion of the purchase price will
     be allocated to core deposit intangible and goodwill. As a condition to
     closing imposed by the bank regulators, the Company has entered into a
     definitive agreement with the Bank of the Rockies to divest of the
     Lewistown branch of its subsidiary, Western Security Bank. The Lewistown
     branch has approximately $19 million in loans and $26 million in deposits.

     Acquisitions are accounted for under the purchase method of accounting.
     Accordingly, the assets and liabilities of the acquired 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 since the date of acquisition. 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.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Impact of Recently Issued Accounting Standards

The Company adopted SFAS No. 123 (Revised) Share-Based Payment, as of January 1,
2006 and, accordingly, has determined compensation cost based on the fair value
of the option at the grant date. Net earnings was reduced as a result of the
adoption of SFAS 123(R) Share-based Payment beginning January 1, 2006, which
requires recording the estimated fair value of stock options as compensation
expense. For additional information regarding the standard see Note 6 to the
Consolidated Financial Statements. The following table illustrates the affect of
the adoption of SFAS 123(R) if it would not have been adopted in 2006.

At September 30, 2006 total assets were $4.127 billion, which is $420 million,
or 11 percent, greater than the December 31, 2005 assets of $3.706 billion.
Without the acquisition of Morgan total assets increased $331 million, or 9
percent, from year end 2005. Of the $537 million increase in total assets since
September 30, 2005, $296 million, or 8 percent, was from internal growth.

Total loans have increased $422 million from December 31, 2005, or 17 percent,
with the growth occurring in all loan categories. The Morgan acquisition
accounted for $42 million, or 2 percent of the increase. Including loans
acquired, commercial loans have increased $203 million, or 15 percent, real
estate loans gained $150 million, or 25 percent, and consumer loans grew by $69
million, or 15 percent. Total loans have increased $590 million, or 26 percent,
with internal loan growth of $436 million, from September 30, 2005, with all
loan categories showing increases. Including loans acquired, commercial loans
increased the most, $277 million, or 22 percent, followed by real estate loans
which increased $219 million, or 41 percent, which was the largest percentage
gain, and consumer loans, which are primarily comprised of home equity loans,
increasing by $93 million, or 21 percent.

Investment securities, including interest bearing deposits in other financial
institutions, and federal funds sold have decreased $75 million from December

September 30, 2005. Investment securities, without interest bearing deposits and
federal funds sold, have decreased $125 million from December 31, 2005, and $182
million from September 30, 2005. Investments, including interest bearing
deposits and federal funds sold, at September 30, 2006 represented 22% of total
assets versus 29% the prior year, which is a result of the continued use of
investment cash flow to fund loan growth.

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 nine months
ended September 30, 2006 and 2005 were $329 million and $331 million,
respectively, and for the three months ended September 30, 2006 and 2005 were
$119 million and $156 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 September
30, 2006 was approximately $170 million.

Non-interest bearing deposits have increased $85 million, or 13 percent, since
December 31, 2005, and by $67 million, or 10 percent, since September 30, 2005.
Acquisitions accounted for $14 million of the 2006 increase and $36 million of
the increase from September 30, 2005. This low cost of funding continues to be a
primary focus of each of our banks. Interest bearing deposits have increased
$232 million since December 31, 2005, with Brokered and National Market CD's
adding $68 million, and the Morgan acquisition adding $53 million to the total.
Since September 30, 2005 interest bearing deposits have increased $397 million,
or 23 percent, with $127 million of that amount from broker and Internet
sources, and $140 million from acquisitions. Federal Home Loan Bank (FHLB)
advances decreased $25 million, and repurchase agreements and other borrowed
funds increased $17 million from December 31, 2005. FHLB advances are $277
million less than the September 30, 2005 balances due primarily to the above
described increases in deposits and other funding sources including $163 million
in U.S. Treasury Tax and Loan Term Auction funds, and $30 million additional
subordinated debentures.

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 earnings. In addition, all of the banking subsidiaries are
members of the FHLB. As of September 30, 2006, the Company had $928 million of
available FHLB borrowing line of which $377 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.

Non-performing assets as a percentage of total bank assets at September 30, 2006
were at .22 percent, the same percentage as at September 30, 2005, but
decreasing slightly from .26 percent at December 31, 2005. The Company ratios
compare favorably to the Federal Reserve Bank Peer Group average of .43 percent
at June 30, 2006, the most recent information available. The allowance for loan
losses was 455 percent of non-performing assets at September 30, 2006, up from
439 percent a year ago. The allowance, including $3.555 million from
acquisitions, has increased $8.710 million, or 25 percent, from a year ago. The
allowance of $43.216 million, is 1.51 percent of September 30, 2006 total loans
outstanding, down slightly from the 1.52 percent a year ago. The

provision for loan losses expense was $3.840 million for the first nine months
of 2006, a decrease of $809,000, or 17 percent, from the same period in 2005.
Net charged off loans was $42 thousand, or .001% of loans, for the nine months
ended September 30, 2006. Loan growth, average loan size, and credit quality
considerations will determine the level of additional provision expense.

 RESULTS OF OPERATIONS -- THE THREE MONTHS ENDED SEPTEMBER 30, 2006 COMPARED TO
                   THE THREE MONTHS ENDED SEPTEMBER 30, 2005.

The Company reported net quarterly earnings of $15.806 million, an increase of
$2.231 million, or 16 percent, over the $13.575 million for the third quarter of
2005. Net quarterly earnings were reduced by $519,000, or $0.02 per share, due
to the January 1, 2006 adoption of SFAS 123(R) Share-based Payment which
requires recording the estimated fair value of stock options as compensation
expense. Diluted earnings per share for the quarter of $0.47 is an increase of
12 percent over the per share earnings of $0.42 for the same quarter of 2005.
Excluding the affects of SFAS 123(R), diluted earnings per share would have been
$0.49, or an increase of 17 percent over the prior year quarter. Annualized
return on average assets and return on average equity for the quarter were 1.58
percent and 16.24 percent, respectively, which compares with prior year returns
for the third quarter of 1.52 percent and 17.88 percent.

Net Interest Income

Net interest income for the quarter increased $5.245 million, or 16 percent,
over the same period in 2005, and $1.379 million from the second quarter of
2006. Total interest income increased $14.322 million from the prior year's
quarter, or 29 percent, while total interest expense increased $9.077 million,
or 57 percent. The increase in interest expense is primarily attributable to the
volume increase in interest bearing deposits, and increases in short term
interest rates during 2005 continuing into 2006. The net interest margin as a
percentage of earning assets for the quarter, on a tax equivalent basis, was
4.28 percent which was 4 basis points higher than the 4.24 percent result for
the third quarter of 2005. The margin for the third quarter of 2006 decreased 6
basis points from the second quarter of 2006 margin of 4.34 percent, primarily a
result of the continued increase in funding costs. Issuing the $30 million
subordinated debentures in advance of acquisitions also reduced net interest
income by approximately $62,000 in the third quarter of 2006.

Non-interest Income

Fee income increased $1.022 million, or 12 percent, over the same period last
year, driven primarily by an increased number of loan and deposit accounts from
internal growth and acquisitions. Gain on sale of loans decreased $266 thousand,
or 8 percent, from the third quarter of last year. Loan origination volume in
our markets

for housing construction continues to remain very active by historical standards
and the recent decline was expected with the slow down from unprecedented
activity last year and as interest rates increased. Other income rose $672,000
of which $543,000 was non-recurring bank owned life insurance proceeds.

Non-interest Expense

Non-interest expense increased by $3.668 million, or 15 percent, from the same
quarter of 2005. Compensation and benefit expense increased $2.307 million, or
17 percent. Excluding SFAS 123(R) compensation cost of $726 thousand the
increase would have been 12 percent. The remaining increase in compensation and
benefit expense was primarily attributed to four acquisitions during 2005 and
normal compensation increases for job performance and increased costs for
benefits. The number of full-time-equivalent employees has increased from 1,052
to 1,200, an 14 percent increase, since September 30, 2005. Occupancy and
equipment expense increased $519 thousand, or 15 percent, reflecting the bank
acquisitions, cost of additional branch locations and facility upgrades. Other
expenses increased $814 thousand, or 13 percent, primarily from acquisitions,
additional marketing expenses, and costs associated with new branch offices. The
efficiency ratio (non-interest expense/net interest income + non-interest
income) was 53 percent for the 2006 quarter, up from 52 percent for the 2005
quarter.

     OPERATING RESULTS FOR NINE MONTHS ENDED SEPTEMBER 30, 2006 COMPARED TO
                               SEPTEMBER 30, 2005

Net earnings for the nine months ended September 30, 2006 were $44.101 million,
which is an increase of $5.916 million, or 15 percent over the prior year.
Diluted earnings per share of $1.33 is an increase of 10 percent over the $1.21
earned in the first nine months of 2005. Excluding SFAS 123(R) compensation
costs of $1.703 million, diluted earnings per share increased 14 percent for the
first nine months of 2006. The 2006 nine month annualized return on average
assets and return on average equity was 1.53 percent and 16.42 percent,
respectively, which compares with prior year nine month returns of 1.51 percent
and 17.67 percent.

Net Interest Income

Net interest income for the nine months increased $18.636 million, or 20
percent, over the same period in 2005. Total interest income increased $43.155
million, or 32 percent, while total interest expense increased $24.519 million,
or 58 percent. The increase in interest expense is primarily attributable to the
volume increase in interest bearing deposits, and increases in short term
interest rates during 2005 and continuing in 2006. The net interest margin as a
percentage of earning assets, on a tax equivalent basis, was 4.33 percent which
was 16 basis points higher than the 4.17 percent result for 2005.

Non-interest Income

Total non-interest income increased $4.859 million, or 15 percent in 2006. Fee
income increased $4.256 million, or 19 percent, over last year, driven primarily
by an increased number of loan and deposit accounts, acquisitions, and
additional customer products and services offered. Gain on sale of loans
decreased $282 thousand, or 3 percent, from the first nine months of last year.
Loan origination volume in our markets for housing continues to remain very
active by historical standards and the recent decline was expected with the slow
down from unprecedented activity last year. Other income increased $750,000 of
which $543,000 was non-recurring bank owned life insurance proceeds.

Non-interest Expense

Non-interest expense increased by $14.895 million, or 23 percent, from the same
nine months of 2005. Compensation and benefit expense increased $9.939 million,
or 27 percent. Excluding SFAS 123(R) compensation cost of $2.410 million the
increase would have been 20 percent. The remaining increase in compensation and
benefit expense was primarily attributed to four acquisitions during 2005, the
addition of five new bank branches in 2006, and normal compensation increases
for job performance and increased costs for benefits. Occupancy and equipment
expense increased $1.434 million, or 15 percent, reflecting the acquisitions,
cost of additional locations and facility upgrades. Other expenses increased
$2.594 million, or 15 percent, primarily from acquisitions, additional marketing
expenses, and costs associated with new branch offices. The efficiency ratio
(non-interest expense/net interest income + non-interest income) increased to 53
percent from 52 percent for the first nine months of 2005 largely a result of
the recent acquisitions and branch openings.

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


                                       28



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 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

information about the Company's market risk than was provided in the Form 10-K

have materially affected, or are reasonably likely to materially affect the
