Item 5.   Other Events and Required FD Disclosure.

     On February 21, 2003, FirstBank NW Corp. ("FirstBank") entered into a
Merger Agreement (the "Agreement") with Oregon Trail Financial Corp. ("Oregon
Trail"), Baker City, Oregon. Under the terms of the Agreement, Oregon Trail
will be merged with and into FirstBank. The Agreement also provides for the
merger of Oregon Trail's subsidiary financial institution, Pioneer Bank, A
Federal Savings Bank, with and into FirstBank's subsidiary financial
institution, FirstBank Northwest.

     Under the terms of the Agreement, Oregon Trail shareholders may elect to
receive either $22.00 in cash or 1.031 shares of FirstBank common stock in
exchange for their shares of Oregon Trail common stock. The election of the
Oregon Trail shareholders will be subject to the allocation and proration
procedures set forth in the Agreement such that the transaction will qualify
as a tax free reorganization for federal income tax purposes. The aggregate
purchase price for the transaction is approximately $73.9 million.

     On September 8, 2003, Oregon Trail issued a press release announcing the
mailing of election forms to shareholders of Oregon Trail as of September 5,

allocation and proration procedures.  Oregon Trail shareholders have until
5:00 p.m., Eastern Daylight Time, on October 14, 2003 to return their Election
Form and Letter of Transmittal.  The specific terms and requirements that need
to be followed for shareholders to make a proper election are contained in the
