     Earnings Summary

     (Unaudited - $ in thousands,           Three months
      except per share data)              ended March 31,

through the rest of the year."

       Total Assets       $2,829,041    $2,322,506     $506,535        22%



    At March 31, 2004 total assets were $2.829 billion which is $507 million
greater than the March 31, 2003 assets of $2.323 billion, an increase of
22 percent.  In addition to the internal growth, the third quarter 2003 Pend
Oreille Bank (POB) acquisition added $66 million to the asset base.

    Total loans have increased $178 million from March 31, 2003, of which
$50 million was from the POB acquisition. Commercial loans have increased
$169 million, or 24 percent, and continue to be the focus of our lending.
Real estate loan volume was at record levels through much of 2003, with
$805 million originated for the year, up from $588 million in 2002.  The
majority of the real estate loan production was sold with loans held in the
loan portfolio increasing by only $14 million.  Loans held for sale declined
$21 million from the March 31, 2003 total resulting in a net reduction of
$7 million in real estate loan balances at March 31, 2004.  Consumer loans
have increased $16 million resulting from increases in home equity loans.
Home-equity loans continue to be the primary source of our consumer loan
originations and have increased approximately $28 million from a year ago.
"Loan growth has been a top priority for us this past year," said Blodnick.
"We continue to operate in good markets that have demonstrated solid and
consistent growth.  This growth has created opportunities for us to increase
our loan portfolio.  Our banks have done a good job of taking advantage of
these strong markets."

    Investment securities, including interest bearing deposits in other
financial institutions, have increased $342 million from March 31, 2003.
Additional investments were made to utilize funding liquidity that exceeded
loan growth opportunities, and to capture the value of the spread between
short term funding rates and the rate on two-to-five year maturity assets.

    Total deposits have increased $115 million from the March 31, 2003
balances of which $59 million came with the POB acquisition.  There was an
increase of $59 million, or 19 percent, in non-interest bearing deposits.
This growth in low cost stable funding gives us increased flexibility in
managing our asset mix.  Interest-bearing deposits are up $57 million, or
5 percent, of which $49 million was added by the POB acquisition.  Federal
Home Loan Bank advances have also increased $301 million as we continue to
take advantage of the flexibility of that funding source in this current
period of low interest rates.  On March 24, 2004 subordinated debentures in
the form of trust preferred securities of $45 million, with an interest rate
of 5.79 percent, were issued by the Company.  The proceeds will be used for
general corporate purposes.

from the prior year, primarily the result of earnings retention, and stock
options exercised.  Net unrealized gains on securities increased $3.4 million

changes.

    Net Interest Income

    Net interest income for the quarter increased $4.557 million, or
21 percent, over the same period in 2003.  Total interest income was
$3.403 million, or 11 percent higher than the same quarter in 2003, while
total interest expense was $1.154 million or 11 percent lower.  The decrease
in interest expense is partly attributed to the increase in non-interest
bearing deposits which reduced the need to borrow funds.  The net interest
margin as a percentage of earning assets, on a tax equivalent basis, decreased
from 4.35 percent for the 2003 quarter to 4.29 percent for the first quarter
of 2004.  The net interest margin increased from the 4.17 percent for the
fourth quarter of 2003 and was higher than any of the last three quarters of
2003.  Premium amortization on mortgage related investments for the current
quarter was $2.553 million, down from the $3.884 million during the fourth
quarter of 2003, and approximately the same level as last year's quarter.
Mortgage security prepayments have slowed resulting in less amortization
expense allowing our net interest margin to stabilize.  We continue to deploy
a strategy of investing in short term securities that carry lower current
yields.  We believe it is inappropriate in this rate environment to extend
maturities in order to achieve higher yields.


    Non-interest Income

    Fee income increased 10 percent over the same period last year, driven
primarily by an increased number of loan and deposit accounts.  Gain on sale
of loans decreased $500 thousand from the first quarter of last year and
$163 thousand from the fourth quarter of 2003, reflecting the reduced mortgage
loan refinancing activity.  Other income, which includes a variety of
activities, was $12 thousand lower than the prior year's quarter.  In the
first quarter of 2003 a valuation impairment charge of $454 thousand, due to
rapid prepayment of mortgage-backed securities, was netted against a
$17 thousand gain on sale of investments and recorded as a net loss on sale of
investments.  There were no realized gains or losses on investments in the
first quarter of 2004.

    Non-interest Expense

    Non-interest expense increased by $2.543 million, or 17 percent, from the
same quarter of 2003.  Current year includes expenses of the three branches
from the POB acquisition, two additional branches in Boise, Idaho, and a new
branch in downtown Bozeman, one of the fastest growing cities in Montana.
Compensation and benefit expense increased $1.827 million, or 23 percent from
the first quarter of 2003 with the additional bank branches, and normal
compensation increases for job performance, accounting for the majority of the
increase.  Outsourced data processing expense decreased by $149 thousand, the
result of bringing the core processing for all subsidiaries onto our in-house
data system.  Other expenses increased $713 thousand, or 20 percent, primarily
from start up expenses on implementing the High Performance Checking program
at the four banks not previously on the program, additional advertising
expense, and costs associated with the new branch offices.  The efficiency
ratio (non-interest expense/net interest income + non-interest income) was
52 percent for the 2004 quarter the same as the 2003 quarter.
