NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Western Sierra Bancorp and subsidiaries (the "Company") have been prepared in
accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and
Article 10 of Regulation S-X. In the opinion of management, all adjustments (which consist solely of normal recurring accruals) considered necessary for a fair presentation
of the results for the interim periods presented have been included. These interim condensed consolidated financial statements should be read in conjunction with the financial statements and related
notes contained in the Company's 2000 Annual Report to Shareholders.

The
condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Western Sierra National Bank (WSNB) and Lake Community Bank
(LCB). All significant inter-company balances and transactions have been eliminated. Operating results for the three and nine months ended September 30, 2001 are not necessarily indicative of
the results that may be expected for the year ending December 31, 2001. Certain amounts in the consolidated financial statements for the year ended December 31, 2000 have been
reclassified to conform to the presentation of the consolidated financial statements in 2001.

2.  Earnings per Share

Basic earnings per share (EPS), which excludes dilution, is computed by dividing net income by the weighted-average number of common shares outstanding for the
period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock, such as stock options, result in the issuance of common stock which shares
in the earnings of the Company. Earnings per share is retroactively adjusted for stock dividends for all periods presented. A reconciliation of the numerators and denominators of the basic and diluted
EPS computations is as follows (dollars in thousands, except for per share data).

3.  Stock Repurchase Plan

On June 21, 2001, the Company announced that its Board of Directors approved a plan to repurchase up to 5% (or 160,000 shares) of the Company's common
stock. During the third quarter of 2001, the Company repurchased 111,500 shares at an average price of $14.95 per share. Year to date

purchases total 140,000 shares at an average price of $14.83 per share. The repurchase is in contemplation of reissuing such shares as part of the banks normal declaration of annual stock dividends.

4.  Recent Accounting Pronouncements

In June 2001, the Financial Accounting Standards Board (FASB) issued SFAS 141,Business
Combinations. This Statement addresses financial accounting and reporting for business combinations, which are to be accounted for using a single methodthe
purchase method. In addition, this Statement requires that intangible assets be recognized as assets apart from goodwill if they meet one of two criteriathe contractual-legal criterion or
the separability criterion. The provisions of this Statement apply to all business combinations initiated after June 30, 2001. This Statement also applies to all business combinations accounted
for using the purchase method for which the date of acquisition is July 1, 2001, or later. The Company has no transactions that meet this criteria.

In
June 2001, the FASB issued SFAS 142,Goodwill and Other Intangible Assets. This Statement addresses financial
accounting and reporting for acquired goodwill and other intangible assets. Goodwill and intangible assets that have indefinite useful lives will not be amortized but rather will be tested annually
for impairment. Intangible assets that have finite useful lives continue to be amortized over their useful lives, but without the constraint of an arbitrary ceiling. Because goodwill will no longer be
amortized. The reported amounts of goodwill will not decrease at the same time and in the same manner as under previous standards. The provisions of this Statement are required to be applied starting
with the years beginning after December 15, 2001. However, goodwill and intangible assets acquired after June 30, 2001, will be subject immediately to the provisions of this Statement.

In
October 2001, the FASB issued Statement No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, that replaces FASB Statement
No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of. The accounting model for long-lived assets to be
disposed of by sale applies to all long-lived assets, including discontinued operations, and replaces the provisions of APB Opinion No. 30, Reporting Results of Operations-Reporting
the Effects of Disposal of a Segment of a Business, for the disposal of segments of a business. Statement 144 requires that
those long-lived assets be measured at the lower of carrying amount or fair value less cost to sell, whether reported in continuing operations or in discontinued operations. Therefore,
discontinued operations will no longer be measured at net realizable value or include amounts for operating losses that have not yet occurred.

Statement
144 also broadens the reporting of discontinued operations to include all components of an entity with operations that can be distinguished from the rest of the entity and
that will be eliminated from the on going operations of the entity in a disposal transaction. The provisions of Statement 144 are effective for financial statements issued for fiscal years beginning
after December 15, 2001 and, generally, are to be applied prospectively. In management's opinion, the adoption of this statement will not have a material impact on the Company's current
financial position or results of operations.

5.  Trust Preferred

On July 10, 2001, Western Sierra Bancorp (Bancorp) formed a wholly owned Connecticut statutory business trust, Western Sierra Statutory Trust I (Western
Trust I) as amended and restated on July 31, 2001. On July 31, 2001 Bancorp issued to Western Trust I Floating Rate Junior Subordinated Deferrable Interest Debentures Due 2031
(Debentures) in the aggregate principal amount of $6,000,000. These debentures qualify as Tier I capital under Federal Reserve Board guidelines. In exchange for these debentures Western Trust I paid
Bancorp $6,000,000. Western Trust I funded its purchase of the debentures by issuing $6,000,000 in floating rate capital securities (capital securities),

which were then pooled and sold. Western Trust I secured capital securities with the Debentures issued by Bancorp. The Debentures are the only asset of Western Trust I. The interest rate on both
instruments is the same and is computed on actual days divided by 360 times the rate. The rate is the three-month LIBOR (London Interbank Offered Rate) plus 3.58% not to exceed 12.5% adjustable
quarterly. The proceeds from the issuance of the Debentures were used to retire short term debt and the related accrued interest ($3,522,000), repurchase stock ($2,076,000) (see note 3), and to
partially fund the construction of the new corporate headquarters ($122,000).

The
Debentures and capital securities accrue and pay distributions quarterly based on the floating rate described above on the stated liquidation value of $1,000 per security. Bancorp
has entered into contractual agreements which, taken collectively, fully and unconditionally guarantee payment of: (1) accrued and unpaid distributions required to be paid on the capital
securities; (2) the redemption price with respect to any capital securities called for redemption by Western Trust I, and (3) payments due upon voluntary or involuntary dissolution,
winding up, or liquidation of Western Trust I.

The
capital securities are mandatorily redeemable upon maturity of the Debentures on July 31, 2031, or upon earlier redemption as provided in the indenture.

Employees.At September 30, 2001, the Company and its subsidiaries employed 193 persons on a

Financial Condition

The Company has grown from $474.6 million at December 31, 2000 to $522.1 million at September 30, 2001, an increase of
$47.5 million. Since the first of the year, total gross loans and leases have increased by $47.4 million and cash and cash equivalents has increased by $10.8 million. This loan
growth and growth in cash and cash equivalents was mostly funded by an increase in deposits $37.4 million and a decrease in investments of $11.9 million.

Results of Operations

The Company reported net income of $1.4 million for the three months ended September 30, 2001 (or $0.41 per share, diluted) compared to
$1.3 million (or $0.36 per share, diluted) for the same period in 2000. The quarterly earnings represent a $112,000 (or 8.57%) increase over the same period in 2000. The Company reported net
income of $3.9 million for the nine months ended September 30, 2001 (or $1.10 per share, diluted) compared to $2.8 million (or $0.77 per share, diluted) for the same period in
2000, an increase of $1,042,000 (or 36.9%).

Factors
contributing to the increase in operating results during the third quarter of 2001 and nine months ended September 30, 2001 as compared to the third quarter of 2000 and
nine months ended September 30, 2000 include:

These
increases in income were offset by an increase in salaries and benefits of $628,000 for the third quarter of 2001 and an increase of $1.2 million
year-to-date. For the third quarter and nine months ended September 30, 2001, occupancy and equipment expense increased by $69,000 and $80,000, respectively. These
increases are attributable to internal growth. The Company had incurred a one-time accrual of $138,000 for a new retirement benefits program for directors during the second quarter of
2001. In addition, the Company did not incur merger costs in the nine months ended September 30, 2001 as compared to $899,000 in the prior year. There were no merger costs in the third quarter
of either year.

Net Interest Income (Tax Equivalent Yield Basis)

Net interest income is the primary source of income for the Company and represents the excess of interest and fees earned on interest-earning assets (loans,
investments and Federal funds sold) over the interest paid on deposits and borrowed funds. Net interest margin is net interest income expressed as a percentage of average earning assets. For the three
months ended September 30, 2001, interest income on a tax equivalent basis increased by $107,000 (or 1.20%) over the same period in 2000. Interest expense on deposit accounts and borrowings
decreased $509,000 (or 13.43%) over the same three-month period in 2000. Average earning assets yielded 7.87% versus 9.16% a year ago, partly offset by a decrease in cost of funds where the average
cost of funds decreased to 3.60% from 4.76% a year ago. Net interest margin decreased 25 basis points to 5.01% from 5.26% for the same period a year ago. The moderate decrease in net interest margin
is attributed to a decreasing interest rate environment as a result of actions taken by the Federal Reserve Board during 2001 and the fact that a significant portion of the Company's investments are
tied to the long-term treasury yield curve which has not decreased at the rate of the short-term yield curve.

For
the nine months ended September 30, 2001, interest income increased $2.1 million (8.38%) over the same period in 2000. Interest expense on deposit accounts and
borrowings increased $499,000 (4.73%) over the same nine-month period in 2000. Net interest margin decreased 21 basis points to 4.88% from 5.09% for the same period a year ago. The
moderate net interest margin decrease is attributed to a decreasing rate environment, average earning assets yielding 8.20% versus 8.76% a year ago, partially offset by a decreased cost of funding
where the average cost of funding has decreased to 4.14% from 4.48% a year ago. This decrease in the cost of funds is due primarily to the easing of short term interest rates by the Federal Reserve
Bank.

The
following table sets forth the Company's daily average balance sheet, related interest income or expense and yield or rate paid for the periods indicated. Tax-exempt
investment yields have been adjusted to a tax-equivalent yield basis, based on a 40% average tax rate (dollars in thousands).

Noninterest Income

The Company's noninterest income primarily consists of service charges on deposit accounts and other service fees, mortgage loan origination and processing
fees and net gains on the sale of investment securities. For the three months ended September 30, 2001, noninterest income increased $396,000 (or 38%) over the same period in 2000. In addition,
income from mortgage loan origination

and packaging fees increased $351,000 (or 98%) over the same period in the prior year. The reasons for the increases are threefold:



For
the nine months ended September 30, 2001, noninterest income increased $1.4 million (or 54%) over the same period in 2000. The increase was due to loan origination
and packaging fees and gains on the sale of securities as discussed previously.

Noninterest Expense

Noninterest consists of salaries and related employee benefits, occupancy and equipment, data processing fees, professional fees, directors' fees, merger and
acquisition costs and other operating expenses. For the three months ended September 30, 2001, noninterest expense increased $660,000 (16.9%) over the same period in 2000. For the nine months
ended September 30, 2001, noninterest expense increased $1.0 million (8.2%) over the same period in 2000.

Salary
and benefits increased $628,000 (32.2%) over the same three-month period last year. This increase was due primarily to the integration of the former Sentinel employees into the
Company's bonus program, the increase in commissions related to the increased income on mortgage loan origination and packaging fees and the implementation of new company-wide incentive
programs. These expenses for the nine month period ended September 30, 2001 increased $1.2 million (20.7%) over the same period in the prior year for similar reasons.

The
Company's effective tax rate varies with changes in the relative amounts of its non-taxable income and non-deductible expenses. The increase in the
Company's tax provision is attributable to increases in the Company's net income and the relative amount of tax-exempt income.

Asset Quality

The Company concentrates its lending activities primarily within areas directly serviced by branches as previously discussed.

The
Company manages its credit risk through diversification of its loan portfolio and the application of underwriting policies and procedures and credit monitoring practices. Although
the Company has a diversified loan portfolio, a significant portion of its borrowers' ability to repay their loans is dependent upon the professional services and residential real estate development
industry sectors. Generally, the loans are secured by real estate or other assets and are expected to be repaid from the cash flows of the borrower or proceeds from the sale of collateral.

The
Company's nonaccrual loans decreased from $1.2 million to $933,000 in the first three months of 2001, but increased from $933 thousand to $3.7 million during
the second quarter of 2001 and decreased from $3.7 million to 3.6 million in the third quarter of 2001. In October one nonaccrual loan for $1.2 million was paid in full and
another loan for $981,000 resumed payments.

Allowance for Loan and Lease Losses (ALLL)

The Company makes provisions to the ALLL on a regular basis through charges to operations that are reflected in the Company's statements of income as a
provision for loan and lease losses. When a loan or lease is deemed uncollectible, it is charged against the allowance. Any recoveries of previously charged-off loans are credited back to
the allowance. There is no precise method of predicting specific losses or amounts that ultimately may be charged-off on particular categories of the loan portfolio.

Similarly,
the adequacy of the ALLL and the level of the related provision for possible loan and lease losses is determined on a judgment basis by management based on consideration of
(i) economic conditions, (ii) borrowers' financial condition, (iii) loan impairment, (iv) evaluation of industry trends, (v) industry and other concentrations,
(vi) loans which are contractually current as to payment terms but
demonstrate a higher degree of risk as identified by management, (vii) continuing evaluation of the performing loan portfolio, (viii) monthly review and evaluation of problem loans
identified as having loss potential, (ix) quarterly review by the Board of Directors, (x) off balance sheet risks and (xi) assessments by regulators and other third parties.
Management and the Board of Directors evaluate the ALLL and determine its desired level considering objective and subjective measures, such

17

as knowledge of the borrowers' business, valuation of collateral, the determination of impaired loans or leases and exposure to potential losses.

The
ALLL is a general reserve available against the total loan and lease portfolio and off balance sheet credit exposure. It is maintained without any interallocation to the
categories of the loan portfolio, and the entire allowance is available to cover loan and lease losses. While management uses available information to recognize losses on loans and leases, future
additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the
Company's ALLL. Such agencies may require the Company to provide additions to the allowance based on their judgment of information available to them at the time of their examination. There is also
uncertainty concerning future economic trends. Accordingly, it is not possible to predict the effect future economic trends may have on the level of the provision for possible loan and lease losses in
future periods.

The
ALLL should not be interpreted as an indication that charge-offs in future periods will occur in the stated amounts or proportions.

The
adequacy of the ALLL calculation is based on three components. First is the dollar weighted risk rating of the loan portfolio, including all outstanding loans and leases, off
balance sheet items, and commitments to lend. Every extension of credit has been assigned a risk rating based upon a comprehensive definition intended to measure the inherent risk of lending money.
Each rating has an assigned risk factor expressed as a reserve percentage. Secondly, established specific reserves are assigned to individual loans currently on the Company's Problem Loan Reports.
These are estimated potential losses associated with specific borrowers based upon collateral value and event(s) causing the risk rating. Thirdly, the Company maintains an unallocated reserve for
qualitative factors that may effect the portfolio as a whole, such as those factors described above.

Management
believes the assigned risk grades and methods for managing changes in assigned risk grades are satisfactory.

Investment Portfolio

Total investment securities decreased $11.9 million in the first nine months of 2001 or 16.8%. The decrease was primarily due to prepayment of loans
underlying the mortgage-backed securities as a result of the decrease in rates. The decrease in investments was used to partially fund the $47.4 million increase in the loan and lease
portfolio.

Liquidity

A Funds Management Policy has been developed by the Company's management and approved by the Company's Board of Directors which establishes guidelines for the
investments and liquidity of the Company. The goals of this policy are to provide liquidity to meet the financial requirements of the Company's customers, maintain adequate reserves as required by
regulatory agencies and maximize earnings of the Company. Liquidity of the Company at September 30, 2001 was 20.4% and December 31, 2000 was 19.8%, based on liquid assets (consisting of
cash and due from banks, investments not pledged, federal funds sold and loans available-for-sale) divided by total liabilities. The Company's management believes it maintains
adequate liquidity levels.

Capital Adequacy

Overall capital adequacy is monitored on a day-to-day basis by the Company's management and reported to the Company's Board of
Directors on a monthly basis. The Bank's regulators measure capital adequacy by using a risk-based capital framework and by monitoring compliance with minimum leverage ratio guidelines.
Under the risk-based capital standard, assets reported on the Company's balance sheet and certain off-balance sheet items are assigned to risk categories, each of which is
assigned a risk weight.

19

---

This standard characterizes an institution's capital as being "Tier 1" capital (defined as principally comprising shareholders' equity) and "Tier 2" capital (defined as principally
comprising the qualifying portion of the ALLL).

The
minimum ratio of total risk-based capital to risk-weighted assets, including certain off-balance sheet items, is 8%. At least
one-half (4%) of the total risk-based capital (Tier 1) is to be comprised of common equity; the balance may consist of debt securities and a limited portion of the ALLL.

The
following table sets forth the Company's and its banking subsidiaries/capital ratios as of the dates indicated.

|                                                  |  | September 30, 2001 |   | December 31, 2000 |  
|------------------------------------------------- |  | ------------------ | - | ----------------- | -
|
|Total risk-based capital to risk-weighted assets  |  | 11.33              | % | 10.71             | %
|Tier 1 capital to risk-weighted assets            |  | 10.08              | % | 9.59              | %
|Tier 1 capital to average assets (leverage ratio) |  | 9.39               | % | 7.92              | %

Much
of the increase in the capital ratios is due to the new trust preferred debentures (see note 5) totaling $6 million. This increase was partially offset by a
repurchase of common stock of $2 million (see note 3). The common stock repurchase was mitigated by an exercise of options for $467,000. The balance of changes were due to normal
operations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

As a financial institution, the Company's primary component of market risk is interest rate volatility. Fluctuation in interest rates will ultimately impact
both the level of income and expense recorded on a large portion of the Company's assets and liabilities, and the market value of all interest earning assets
and interest bearing liabilities, other than those which possess a short term to maturity. Virtually all of the Company's interest earning assets and all of the Company's interest bearing liabilities
are located at the banking subsidiary level. Thus, virtually all of the Company's interest rate risk exposure lies at the banking subsidiary level. As a result, all significant interest rate risk
management procedures are performed at the banking subsidiary level. The Company's real estate loan portfolios, concentrated primarily within northern California, are subject to risks associated with
the local economies.

The
fundamental objective of the Company's management of its assets and liabilities is to maximize the Company's economic value while maintaining adequate liquidity and an exposure to
interest rate risk deemed by management to be acceptable. Management believes an acceptable degree of exposure to interest rate risk results from the management of assets and liabilities through
maturities, pricing and mix to attempt to neutralize the potential impact of changes in market interest rates. The Company's profitability is dependent to a large extent upon its net interest income
that is the difference between its interest income on interest-earning assets, such as loans and investments, and its interest expense on interest-bearing liabilities, such as deposits and borrowings.
The Company is subject to interest rate risk to the degree that its interest-earning assets reprice differently than its interest-bearing liabilities. The Company manages the mix of assets and
liabilities with the goals of limiting its exposure to interest rate risk, ensuring adequate liquidity, and coordinating its sources and uses of funds.

The
Company seeks to control interest rate risk exposure in a manner that will allow for adequate levels of earnings and capital over a range of possible interest rate environments.
The Company has adopted formal policies and practices to monitor and manage interest rate risk exposure. As part of this effort, the Company measures interest rate risk utilizing third-party sources
that are based on the Call Reports of the individual subsidiary banks' data that is downloaded from the mainframe computer system and management's assumptions. This analysis determines the affect that
100 and 200 basis point changes in the prime rate up or down have on net interest income over a projected twelve-month period.
