                         INDEPENDENT AUDITORS' REPORT

To the Administrative Committee
Pioneer Bank, FSB Profit Sharing 401(k) Plan
Baker City, Oregon

We have audited the accompanying statements of net assets available for
benefits of Pioneer Bank, FSB Profit Sharing 401(k) Plan as of December 31,
2002 and 2001, and the related statement of changes in net assets available
for benefits for the year ended December 31, 2002.  These financial statements
are the responsibility of the Plan's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with U.S. generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of Pioneer Bank,
FSB Profit Sharing 401(k) Plan as of December 31, 2002 and 2001 and the
changes in net assets available for benefits for the year ended December 31,
2002 in conformity with U.S. generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedule of assets
held for investment purposes is presented for purposes of additional analysis
and are not a required part of the basic financial statements but is
supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974.  The supplemental schedules have been subjected to the
auditing procedures applied in our audits of the basic financial statements
and, in our opinion, are fairly stated in all material respects in relation to
the basic financial statements taken as a whole.

                         December 31, 2002 and 2001

NOTE A - DESCRIPTION OF THE PLAN

General
- -------

The following description of the Pioneer Bank, FSB (the Employer) Profit
Sharing 401(k) Plan (the Plan) provides general information.  Participants
should refer to the Plan agreement for a description of the Plan provisions.

The Plan is a profit sharing plan established July 1, 1959, to provide
retirement and incidental benefits to eligible employees.  The Plan is subject
to the provisions of the Employee Retirement Income Security Act of 1974
(ERISA).

All regular employees are eligible to participate in the Plan upon attaining
the age of 18 and completing one hour of service.

Prudential Mutual Fund Management, Inc. is the Plan Administrator and
Custodian.  The Trustees are Michelle D. Kaseberg, William H. Winegar,
Jonathan McCreary, and Anne Raffetto.

Employee Contributions
- ----------------------

Participants may elect to defer up to 10% of their annual compensation, as
defined by the Plan, up to the maximum deferrable amount allowed by the
Internal Revenue Service.  The Plan accepts rollover contributions of amounts
distributed from another qualified plan or a qualified individual retirement
account.  Participants may elect to deposit their contributions in any of the
investment options available.

Employer Contributions
- ----------------------

The Employer makes dollar-for-dollar matching contributions to a participant's
account up to a maximum of 3.33% of the participant's annual pretax
compensation that is beneath the annual compensation limit imposed by the IRS.

Additional Employer contributions may be made on a discretionary basis, in
amounts determined by the Employer annually.  Employer contributions are
allocated to all employees who are eligible for the Plan and employed on the
last day of the Plan year, as well as employees who died or became disabled
during the Plan year, and former employees who retired under the Plan.
Employer contributions are allocated based on the ratio of each participant's
compensation in relation to total compensation of all eligible participants.

                            December 31, 2002 and 2001

Vesting
- -------

Participants are, at all times, fully vested in their employee account
balance.  Participants become vested in their employer account balance over a
six-year period based upon their years of service with the employer as
follows:

             Years of                                Percentage of
             Service                                Vested Interest
             --------                               ---------------

             Less than 2 years                             0%
             2 years                                      20%
             3 years                                      40%
             4 years                                      60%
             5 years                                      80%
             Six or more years                           100%

Participants vest immediately in their employee deferrals and rollover
contributions plus actual earnings thereon.  The Plan provides for
participants to be fully vested upon death, permanent disability or the
attainment of age 65.

Distributions
- -------------

Upon a participant's retirement, death or separation from service,
participants may elect either a lump sum cash payment or, if the value of the
benefit exceeds $5,000, approximate equal payments made at least once a year
over a period not to exceed the life expectancy of the participant or
beneficiary.

The Plan has provisions for hardship withdrawals from the participant's
deferral account.  Matching contributions and allocated earnings are not
available for hardship withdrawals.

Forfeitures
- -----------

Upon termination of employment with the Employer, participants are entitled to
a distribution of their vested account balances. Forfeitures of terminated
participant's non-vested benefits are applied to pay administrative expenses
and reduce the Employer's contributions to the Plan.  For the years ended
December 31, 2002 and 2001, there were $17,971 and $4,621 of forfeited account
balances, respectively.

                          December 31, 2002 and 2001

Participant Accounts
- --------------------

Each participant's account is credited with the employee's contributions and
the employer's discretionary matching contributions.  Dividend and interest
income, net of administrative expenses with respect to each category of
investments, is allocated to participants' accounts based upon their pro-rata
share of the equity in each investment fund before such allocation.

Expenses
- --------

Substantially all administration expenses of the Plan are paid by the Employer
on behalf of the Plan and will not be reimbursed.  The participant pays
expenses incident to certain transactions.

Termination
- -----------

Although the Employer expects to continue the Plan indefinitely, the Employer
may terminate the Plan in whole or in part at any time upon giving written
notice to the Administrator and Trustee.  If the Plan is terminated, the
account of each participant will be fully vested and non-forfeitable as of the
effective date of the Plan termination.

Participant Loans
- -----------------

Participants may borrow from their fund accounts up to a maximum equal to the
lesser of $50,000 or 50% of their vested account balance.  Loan transactions
are treated as a transfer from the investment to the Loan Fund.  Payments on
loans are treated as a transfer from the Loan fund to the investment.  Loan
terms generally range from 1-10 years with principal and interest payments
monthly.  The loans are secured by the balance in the participant's account
and bear interest at a rate commensurate with local prevailing rates as
determined by the Plan administrator.

Plan Amendments
- ---------------

The Company has the right to amend or terminate the Plan and Trust Agreement.

NOTE B - SUMMARY OF ACCOUNTING POLICIES

Investment Valuation and Income Recognition
- -------------------------------------------

Investments in guaranteed interest accounts are carried at contract value,
which approximates principal amounts contributed to the accounts, plus accrued
interest, less distributions from the contract.  Investments in all other
investment options are carried at their fair value measured and quoted market
prices in active markets or by the contracted price.  Investment income is
recorded as earned.

Purchases and sales of securities are recorded on a trade-date basis.
Dividends are recorded on the ex-dividend date.

Payment of Benefits
- -------------------

Benefits are recorded when paid.

Estimates
- ---------

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires the plan administrator to make
estimates and assumptions that affect certain reported amounts and
disclosures.  Accordingly, actual results may differ from those estimates.

NOTE C   INVESTMENTS

At December 31, 2002 and 2001, investment that constitute 5% of Plan assets
are as follows:

NOTES TO FINANCIAL STATEMENTS
December 31, 2002 and 2001

NOTE F - INCOME TAX STATUS

The Plan adopted a prototype plan and consequently is relying on the
determination received by the prototype.  The Plan has been amended since
adoption of the prototype plan.  However, the Plan administrator and the
plan's tax counsel believe the Plan is currently designed and being operated
in compliance with the applicable requirements of the Internal Revenue Code.
Therefore, no provision for income taxes has been included in the Plan's
financial statements.

NOTE G   SUBSEQUENT EVENT

Oregon Trail Financial Corp. (the Company) has entered into an agreement to
merge with First Bank Northwest later this year.  It is anticipated by
management that the plan will be terminated after the merger.

                                      -8-
