NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  Management Statement

In the opinion of the Company, the accompanying audited and
unaudited Consolidated Financial Statements present fairly the
financial position of the Company as of June 30, 1997, December 31,
1996, and June 30, 1996, and the results of operations and the
changes in financial position for the six month period ended June
30, 1997 and 1996.

Certain reclassifications of 1996 balances have been made to
conform with the June 30, 1997 presentation; there was no impact on
net income, earnings per share or stockholders' equity.  Also per
share amounts and weighted average shares outstanding have been
retroactively adjusted to reflect a previously disclosed stock
split-ups.

In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standard No. 128 (SFAS 128),
Earnings Per Share, which establishes new standards for computing
and presenting earnings per share.  SFAS 128 is effective for
financial statements issued for periods ending after December 15,
1997 and requires restatement of all prior-period earnings per
share data.  Early application of SFAS 128 is not permitted.  The
Company's adoption of the provision of SFAS 128 will result in the
dual presentation of basic and diluted earnings per share.  The
Company has previously disclosed basic earnings per share.  Diluted
earnings per share as calculated under SFAS 128 is not expected  to
materially differ, if at all from previously disclosed earnings per
share.

NOTE 2.  Securities

Most of the securities are classified as available-for-sale and are
stated at fair value, and unrealized holding gains and losses, net
of related deferred taxes, are reported as a separate component of
stockholders' equity.  Gains or losses on available-for-sale
securities sales are reported as part of noninterest income based
on the net proceeds and the adjusted carrying amount of the
securities sold, using the specific identification method.
Carrying amount and fair values at June 30, 1997 and December 31,
1996 were as follows:

NOTE 4.  ALLOWANCE FOR LOAN LOSSES

The allowance for loan loss is maintained at levels considered
adequate by management to provide for possible loan losses.  The
allowance is based on management's assessment of various factors
affecting the loan portfolio, including problem loans, business
conditions and loss experience, and an overall evaluation of the
quality of the underlying collateral.  Changes in the allowance for
loan loss during the three and six months ended June 30, 1997 and
1996 were as follows:

NOTE 5.  SUBSEQUENT EVENTS

Effective July 18, 1997 the Company acquired five branches from
Wells Fargo Bank.  United Security Bank acquired two of the
branches in Moses Lake and Davenport, Washington.  Home Security
Bank acquired three of the branches in Walla Walla, Mabton, and
Naches, Washington.  These branches are located in the identified
market place for the two Banks.  The acquisitions will increase
deposits by approximately $35 million, premises and equipment by
$1.8 million, and other assets by $2.3 million for the core deposit
acquisition cost.  These acquisitions will increase the Company's
totals beginning in third quarter 1997.

The Company previously disclosed a loss due to an embezzlement by a
former employee of its subsidiary, Home Security Bank.  On July 17,
1997 the Company received from its insurance carrier $637,000.
This represents the reconciled amount of the principal portion
embezzled, less the insurance policy deductible of $50,000.  The
income will increase third quarter 1997 results.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATION (continued)

Net Interest Income

Net interest income grew 11% to $6,536,000 in 1997 compared to
$5,903,000 in 1996.  The increase is primarily the result of loan
growth.  Total loans grew 10% to $185,611,000 as of June 30, 1997
compared to $168,533,000 as of June 30, 1996.  The net interest
margin to average earning assets was 6.14% and 6.33% as of June 30,
1997 and 1996, respectively.

Provision for Loan Losses

The allowance for loan losses grew 26%, comparing June 30, 1997 to
1996, which represents 1.07% and .93% of loans, respectively.

Noninterest Income

Noninterest income decreased by 7% to $1,384,000 during the first
six months of 1997 compared to $1,481,000 for the same period in
1996.  Fees and service charges increased 6% to $583,000 in 1997
from $549,000 in 1996 due to deposit growth patterns.  This was
offset by an 8% decline in insurance commissions, a loss on sales
of available-for-sale securities.  The loss on the sales of
securities allowed the Company to reposition its securities
portfolio to improve the yield on the new securities purchased.

Noninterest Expense

Noninterest expense increased by 3% in 1997 compared to first
quarter 1996.  The Company efficiency ratio was 58.42% for 1997
compared to 60.23% for 1996.

Liquidity and Capital Resources

The company had $18.5 million of cash and cash equivalents as of
June 30, 1997.  As described in other subsequent events the Company
will receive approximately $31 million in liquid funds from the
acquisition of 5 branches in July, 1997.  The funds will be
initially invested in short-term investments until new loans are
originated.  The current and future capital resources of the
Company are allowing future growth with these acquisitions.
