Item 5.  Other Events
- ---------------------

     On October 31, 2003, FirstBank NW Corp. ("FirstBank") and its
wholly-owned subsidiary, FirstBank Northwest consummated the previously
announced acquisition of Oregon Trail Financial Corp. ("Oregon Trail") and its
wholly-owned subsidiary, Pioneer Bank, A Federal Savings Bank, pursuant to the
Merger Agreement, dated as of February 24, 2003, by and between FirstBank and
Oregon Trail.

     The merger was completed through the merger of Oregon Trail with and into
FirstBank with FirstBank being the surviving corporation in the merger.
Pursuant to the terms of the Merger Agreement, Oregon Trail shareholders who
elected to receive FirstBank stock received 1,480,064 shares of FirstBank
common stock and Oregon Trail shareholders who elected to receive cash
received $22.00 in cash for each share of Oregon Trail common stock.  Oregon
Trail shareholders who elected to receive shares of FirstBank common stock
also received a cash payment for their shares, at a rate of $22.00 per share,
because there were not enough available shares of FirstBank common stock to be
exchanged for their Oregon Trail shares. FirstBank issued a total of
approximately 1,480,064 shares and paid a total of approximately $36.5 million
in cash to the former Oregon Trail shareholders.  FirstBank issued the stock
consideration out of its authorized but unissued shares and received dividends
from FirstBank Northwest, and obtained a third-party bridge loan to pay the
cash consideration.

Item 7.  Financial Statements, Pro Forma Financial Information and Exhibits
- ---------------------------------------------------------------------------

     (a)   Financial Statements of Businesses Acquired.

     The historical consolidated financial statements of Oregon Trail,
including its consolidated balance sheets as of September 30, 2003, March 31,
2003 and March 31, 2002, and the related consolidated statements of operations
and comprehensive income (loss), changes in stockholders' equity and cash
flows for each of the years then ended, which are included in FirstBank's
Registration Statement on Form S-4 (File No. 333-106522), are incorporated
herein by reference.

     (b)   Pro Forma Financial Information.

     The unaudited pro forma condensed combined financial statements set forth
below reflect consummation of the merger between FirstBank and Oregon Trail as
if the merger had been consummated on September 30, 2003.  The unaudited pro
forma condensed combined statements of income for each of FirstBank and Oregon
Trail for the six months ended September 30, 2003 and for the year ended March
31, 2003 were prepared as if the merger had been consummated on September 30,
2003.

     The unaudited pro forma condensed combined financial statements and notes
thereto reflect the application of the purchase method of accounting.  Under
the purchase method of accounting, the assets and liabilities of Oregon Trail
are recorded on the books of FirstBank at their fair value as of the effective
time of the merger.  The difference between the cost of Oregon Trail and the
fair value of its identifiable assets, less the fair value of its liabilities,
will be recorded as goodwill.  The





unaudited pro forma condensed combined financial statements included herein
are not necessarily indicative of the future results of operations or the
future financial position of the combined entities or the results of
operations and financial position of the combined entities that would have
actually occurred had the transactions been in effect as of the dates or for
the periods presented.  Such information does not include any pro forma
adjustments relating to any future revenue enhancements and reductions in
expenses that may be realized.

                   Notes to Unaudited Pro Forma Condensed
                        Combined Financial Statements

1.   Basis of Presentation

     The unaudited pro forma condensed combined balance sheets as of September
30, 2003, March 31, 2003 and March 31, 2002 have been prepared as if the
merger had been consummated on September 30, 2003.  The unaudited pro forma
condensed combined statements of income for FirstBank and for Oregon Trail for
the six months ended September 30, 2003 and for the year ended March 31, 2003
were prepared as if the merger had been consummated on September 30, 2003.

     The unaudited pro forma condensed combined financial statements are based
on historical financial statements of FirstBank and Oregon Trail after giving
effect to the merger under the purchase method of accounting and the
assumptions and adjustments in the notes that follow.

     Assumptions relating to the pro forma adjustments set forth in the
unaudited pro forma condensed combined financial statements are summarized as
follows:

     *     Estimated fair values - Estimated fair values for securities, loans
           and deposits were obtained from appropriate valuation methodologies
           and market information used in accordance with Statement of
           Financial Accounting Standards (SFAS) No. 107, Disclosures About
           Values of Financial Instruments.

     *     The resulting premium on loans for purposes of these pro forma
           financial statements is being amortized to interest income using an
           accelerated method over the weighted lives of 3.67 years which
           approximate a constant yield to maturity. The premium on deposits
           will be amortized using an accelerated method over a weighted
           average life of 5.5 years to interest expense which approximate a
           constant yield to maturity.  A core deposit intangible analysis was
           performed that concluded there was $3,876,000 in core deposit
           intangible created as a result of the merger and is being amortized
           to interest expense using an accelerated amortization method that
           approximates a constant yield to maturity.

common stock (plus all options at a cost of $4,563,100 to purchase Oregon

38.36%.


7.   Basic earnings per common share for the six months ended September 30,
2003 and year ended March 31, 2003 is calculated by dividing net income by the
average number of common shares outstanding.  Diluted earnings per common
share is calculated using the same method as basic earning per common share,
but reflects potential dilution of common share equivalents.  Basic and
diluted weighted average number of common stock and common stock equivalents
utilized for the calculation of earnings per share for the periods presented
were calculated using FirstBank historical weighted average common stock and
common stock equivalents plus 1,480,064 shares issued to Oregon Trail
shareholders under the terms of the merger.
