PART I

ITEM 1. DESCRIPTION OF BUSINESS

GENERAL. Western Sierra Bancorp was incorporated under the laws of the State
of California on July 11, 1996. Western Sierra was organized pursuant to a
plan of reorganization for the purpose of becoming the parent corporation of
Western Sierra National Bank, and on December 31, 1996, the reorganization
was effected and shares of Western Sierra common stock were issued to the
shareholders of Western Sierra National Bank for the common shares held by
Western Sierra National Bank's shareholders. In April 1999, Western Sierra
acquired Roseville 1st National Bank and Lake Community Bank in a stock for
stock exchange. In May of 2000, Western Sierra acquired Sentinel Community
Bank in a stock for stock exchange. In addition, these mergers were accounted
for as a pooling of interest and accordingly, all prior period financial
statements have been restated to reflect the combined operations of Western
Sierra, Roseville 1st National Bank, Lake Community Bank and Sentinel
Community Bank. Sentinel Community Bank was merged into Western Sierra
National Bank. Also in May of 2000, Roseville 1st National Bank was merged
into Western Sierra National Bank. In October of 2000, Western Sierra
National Bank purchased the deposits and certain other assets and liabilities
of the Columbia branch of Pacific State Bank. Western Sierra is a registered
bank holding company under the Bank Holding Company Act. Western Sierra
conducts its operations at 3350 Country Club Drive, Suite 202, Cameron Park,
California 95682.

Western Sierra National Bank was organized under national banking laws and
commenced operations as a national bank on January 4, 1984. Western Sierra
National Bank is a member of the Federal Reserve System and its deposits are
insured to the maximum amount permitted by law by the FDIC. Western Sierra
National Bank's head office is located at 4011 Plaza Goldorado Circle,
Cameron Park, and its branch offices are located at 2661 Sanders Drive,
Pollock Pines, 3970 J Missouri Flat Road, Placerville, 1450 Broadway,
Placerville, 3880 El Dorado Hills Blvd., El Dorado Hills, 571 5th Street,
Lincoln, 1545 River Park Dr. #101 & #200, Sacramento, 229 South Washington
Street, Sonora, 13753-A Mono Way, Sonora, 18711 Tiffeni Drive, Twain Harte,
1801 Douglas Blvd., Roseville, 6951 Douglas Blvd., Granite Bay, and 22712
Main Street, Columbia. Western Sierra National Bank does not have any
affiliates or subsidiaries, other than Lake Community Bank and Sentinel
Associates, Inc.

Roseville 1st National Bank was founded in 1983 as Countryside Thrift and
Loan (Countryside). Countryside operated as an industrial loan company until
its conversion to a national bank on July 1, 1992. Roseville 1st National
Bank was merged into Western Sierra National Bank in May of 2000, and
operates as a DBA Roseville 1st National Bank - a branch of Western Sierra
National Bank.

Lake Community Bank was incorporated as a banking corporation under the laws
of the State of California on March 9, 1984 and commenced operations as a
California state-chartered bank on


4


November 15, 1984. Lake Community Bank is an insured bank under the Federal
Deposit Insurance Act and is not a member of the Federal Reserve System. Lake
Community Bank engages in the general commercial banking business in Lake
County in the State of California from its headquarters banking office
located at 805 Eleventh Street, Lakeport, California, and its branch located
at 4280 Main Street, Kelseyville, California. Lake Community Bank does not
have any affiliates or subsidiaries, other than Western Sierra National Bank
and Sentinel Associates, Inc.

Sentinel Community was incorporated under the laws of the State of California
on December 24, 1980, and commenced operations on April 2, 1982. The
corporation was formed as a State Chartered Savings and Loan Association.
Sentinel Community converted its charter to a Federal Savings and Loan
Association on June 9, 1989. In October of 1996, Sentinel Community changed
its name to Sentinel Community Bank, while remaining chartered as a Federal
Savings and Loan Association. Sentinel Community Bank was merged into Western
Sierra National Bank in May, 2000, and operates as a DBA Sentinel Community
Bank - a branch of Western Sierra National Bank.

Western Sierra has an inactive subsidiary (acquired from Sentinel), Sentinel
Associates, Inc., which is administered out of the main office. Sentinel
Associates, Inc., was formed in October, 1983, for the purpose of developing
single family residential real estate.

BANKING SERVICES. Western Sierra is a locally owned and operated bank holding
company, and its primary service area is the Northern California communities
of Cameron Park, Pollock Pines, Placerville, El Dorado Hills, Lincoln,
Sacramento, Roseville, Granite Bay, Sonora, Twain Harte, Columbia, Lakeport
and the surrounding communities. Western Sierra's primary business is
servicing the banking needs of these communities and its marketing strategy
stresses its local ownership and commitment to serve the banking needs of
individuals living and working in Western Sierra's primary service areas and
local businesses, including retail, professional and real estate-related
activities, in those service areas.

Western Sierra offers a broad range of services to individuals and businesses
in its primary service areas with an emphasis upon efficiency and
personalized attention. Western Sierra provides a full line of consumer
services and also offers specialized services, such as courier services to
small businesses, middle market companies and professional firms. Each of
Western Sierra's subsidiary banks offers personal and business checking and
savings accounts (including individual interest-bearing negotiable orders of
withdrawal ("NOW"), money market accounts and/or accounts combining checking
and savings accounts with automatic transfer), IRA accounts, time
certificates of deposit and direct deposit of social security, pension and
payroll checks, computer cash management and internet banking including bill
payment. Western Sierra's subsidiary banks also make available commercial,
construction, accounts receivable, inventory, automobile, home improvement,
real estate, commercial real estate, single family mortgage, agricultural,
Small Business Administration, office equipment, leasehold improvement,
installment and credit card loans (as well as overdraft protection lines of
credit), issue drafts and standby letters of credit, sell travelers' checks
(issued by an independent entity), offer ATMs tied in with major statewide
and


5


national networks, extend special considerations to senior citizens and offer
other customary commercial banking services.

Most of Western Sierra's deposits are obtained from commercial businesses,
professionals and individuals. There is no concentration of deposits or any
customer with 5% or more of any of the subsidiary banks' deposits.

Other special services and products include both personal and business
economy checking products, business cash management products and mortgage
products and services.

EMPLOYEES. At December 31, 2000, Western Sierra and its subsidiaries employed
213 persons on a full-time equivalent basis. Western Sierra believes its
employee relations are excellent.

SUPERVISION AND REGULATION. Western Sierra is a bank holding company within
the meaning of the Bank Holding Company Act of 1956, as amended (BHCA), and
is registered as such with and is subject to the supervision of the Board of
Governors of the Federal Reserve System (the FRB). Generally, a bank holding
company is required to obtain the approval of the FRB before it may acquire
all or substantially all of the assets of any bank, or ownership or control
of the voting shares of any bank if, after giving effect to such acquisition
of shares, the bank holding company would own or control more than 5% of the
voting shares of such bank. The FRB's approval is also required for the
merger or consolidation of bank holding companies.

Western Sierra is required to file reports with the FRB and provide such
additional information as the FRB may require. The FRB also has the authority
to examine Western Sierra and each of its subsidiaries, as well as any
arrangements between Western Sierra and any of its subsidiaries, with the
cost of any such examination to be borne by Western Sierra.

Banking subsidiaries of bank holding companies are also subject to certain
restrictions imposed by federal law in dealings with their holding companies
and other affiliates. Subject to certain restrictions set forth in the
Federal Reserve Act, a bank can loan or extend credit to an affiliate,
purchase or invest in the securities of an affiliate, purchase assets from an
affiliate, or issue a guarantee, acceptance, or letter of credit on behalf of
an affiliate, provided that the aggregate amount of the above transactions of
the bank and its subsidiaries does not exceed 10 percent of the capital stock
and surplus of the bank on a per affiliate basis or 20 percent of the capital
stock and surplus of the bank on an aggregate affiliate basis. In addition,
such transactions must be on terms and conditions that are consistent with
safe and sound banking practices and, in particular, a bank and its
subsidiaries generally may not purchase from an affiliate a low-quality
asset, as that term is defined in the Federal Reserve Act. Such restrictions
also prevent a bank holding company and its other affiliates from borrowing
from a banking subsidiary of the bank holding company unless the loans are
secured by marketable collateral of designated amounts. Further, Western
Sierra and its subsidiaries are prohibited from engaging in certain tie-in
arrangements in connection with any extension of credit, sale or lease of
property or furnishing of services.

A bank holding company is prohibited from itself engaging in or acquiring
direct or indirect ownership or control of more than 5% of the voting shares
of any company engaged in


6


nonbanking activities. One of the principal exceptions to the prohibition is
for activities found by the FRB by order or regulation to be so closely
related to banking or managing or controlling banks as to be a proper
incident thereto. In making these determinations, the FRB considers whether
the performance of such activities by a bank holding company would offer
advantages to the public which outweigh possible adverse effects.

Federal Reserve Regulation Y sets out those activities which are regarded as
closely related to banking or managing or controlling banks, and thus, are
permissible activities that may be engaged in by bank holding companies
subject to approval in individual cases by the FRB. Most of these activities
are now permitted for national banks. There has been litigation challenging
the validity of certain activities authorized by the FRB for bank holding
companies, and the FRB has various regulations in this regard still under
consideration. The future scope of permitted activities is uncertain.

Western Sierra National Bank is subject to primary supervision, examination
and regulation by the Office of the Comptroller of the Currency (the
Comptroller) and also subject to applicable regulations of the FDIC and the
FRB, and in addition the provisions of California law, insofar as they are
not preempted by federal banking law. Lake Community Bank is subject to
primary supervision, examination and regulation by the California Department
of Financial Institutions (DFI) and the FDIC and is subject to applicable
regulations of the FRB. The deposits of both financial institutions are
insured by the FDIC to applicable limits. As a consequence of the extensive
regulation of commercial banking activities in California and the United
States, the subsidiary banks' businesses are particularly susceptible to
changes in California and federal legislation and regulations, which may have
the effect of increasing the cost of doing business, limiting permissible
activities or increasing competition.

Various other requirements and restrictions under the laws of the United
States and the State of California affect the operations of the subsidiary
banks. Federal and California statutes and regulations relate to many aspects
of the banks' operations, including reserves against deposits, interest rates
payable on deposits, loans, investments, mergers and acquisitions,
borrowings, dividends, branching, capital requirements and disclosure
obligations to depositors and borrowers. The Comptroller regulates the number
and locations of the branch offices of a national bank, but may only permit a
national bank to maintain branches in locations and under the conditions
imposed by state laws upon state banks. California law presently permits a
bank to locate a branch office in any locality in the state. Additionally,
California law exempts banks, including national banks, from California usury
laws.

IMPACT OF MONETARY POLICIES. The earnings and growth of Western Sierra are
subject to the influence of domestic and foreign economic conditions,
including inflation, recession and unemployment. The earnings of Western
Sierra are affected not only by general economic conditions but also by the
monetary and fiscal policies of the United States and federal agencies,
particularly the Federal Reserve. The Federal Reserve can and does implement
national monetary policy, such as seeking to curb inflation and combat
recession, by its open market operations in United State Government
securities and by its control of the discount rates applicable to borrowings
by banks from the Federal Reserve System. The actions of the Federal Reserve
in

7


these areas influence the growth of bank loans, investments and deposits and
affect the interest rates charged on loans and paid on deposits. As
demonstrated over the past several years by the Federal Reserve's actions
regarding interest rates, its policies have had a significant effect on the
operating results of commercial banks and are expected to continue to do so
in the future. The nature and timing of any future changes in monetary
policies are not predictable.

RECENT AND PROPOSED LEGISLATION. The operations of Western Sierra are subject
to extensive regulation by federal, state and local governmental authorities
and are subject to the various laws and judicial and administrative decisions
imposing requirements and restrictions on part or all of its operations.
Western Sierra believes that it is in substantial compliance in all material
respects with applicable federal, state and local laws, rules and
regulations. Because the business of Western Sierra and its subsidiaries are
highly regulated, the laws, rules and regulations applicable to each of them
are subject to regular modification and change.

From time to time, legislation is enacted which has the effect of increasing
the cost of doing business, limiting or expanding permissible activities or
affecting the competitive balance between banks and other financial
institutions. Proposals to change the laws and regulations governing the
operations and taxation of banks and other financial institutions are
frequently made in Congress, in the California legislature and before various
bank regulatory agencies. Most recently, the Gramm-Leach-Bliley Act was
signed into law. This legislation eliminates many of the barriers that have
separated the insurance, securities and bank industries since the Great
Depression. The federal banking agencies (the Federal Reserve, FDIC, Office
of the Comptroller of the Currency) among others, are currently drafting
regulations to implement the Gramm-Leach-Bliley Act. The likelihood of any
major change from these regulations, and the impact such change may have on
Western Sierra is impossible to predict.

The Gramm-Leach-Bliley Act, signed into law on November 12, 1999, is the
result of a decade of debate in the Congress regarding a fundamental
reformation of the nations' financial system. The law is subdivided into
seven titles, by functional area. Title I acts to facilitate affiliations
among banks, insurance companies and securities firms. Title II narrows the
exemptions from the securities laws previously enjoyed by banks, requires the
Federal Reserve and the SEC to work together to draft rules governing certain
securities activities of banks and creates a new, voluntary investment bank
holding company. Title III restates the proposition that the states are the
functional regulators for all insurance activities, including the insurance
activities of federally-chartered banks. The law bars the states from
prohibiting insurance activities by depository institutions. The law
encourages the states to develop uniform or reciprocal rules for the
licensing of insurance agents. Title IV prohibits the creation of additional
unitary thrift holding companies. Title V imposes significant requirements on
financial institutions related to the transfer of nonpublic personal
information. These provisions require each institution to develop and
distribute to accountholders an information disclosure policy, and requires
that the policy allow customers to, and for the institution to, honor a
customer's request to "opt-out" of the proposed transfer of specified
nonpublic information to third parties. Title VI reforms the Federal Home
Loan Bank system to allow broader access among depository institutions to the
systems advance programs, and to improve the corporate governance and capital
maintenance requirements for the system. Title VII addresses a multitude of
issues including disclosure of ATM surcharging


8


practices, disclosure of agreements among non-governmental entities and
insured depository institutions which donate to non-governmental entities
regarding donations made in connection with the Community Reinvestment Act,
and disclosure by the recipient non-governmental entities of how such funds
are used. Additionally, the law extends the period of time between CRA
examinations of community banks.

Western Sierra intends to comply with all provisions of the
Gramm-Leach-Bliley Act and all implementing regulations as they become
effective, and intends to develop appropriate policies and procedures to meet
its responsibilities in connection with the privacy provisions of Title V of
that Act.

CONSUMER PROTECTION LAWS AND REGULATIONS. The bank regulatory agencies are
focusing greater attention on compliance with consumer protection laws and
they are implementing regulations. Examination and enforcement have become
more intense in nature and insured institutions have been advised to monitor
carefully compliance with such laws and regulations. Western Sierra is
subject to many federal consumer protection statutes and regulations, some of
which are discussed below.

The Community Reinvestment Act (CRA) is intended to encourage insured
depository institutions, while operating safely and soundly, to help meet the
credit needs of their communities. The CRA specifically directs the federal
regulatory agencies, in examining insured depository institutions, to assess
a bank's record of helping meet the credit needs of its entire community,
including low and moderate-income neighborhoods, consistent with safe and
sound banking practices. The CRA further requires the agencies to take a
financial institution's record of meeting its community credit needs into
account when evaluating applications for, among other things, domestic
branches, mergers or acquisitions, or holding company formations. The
agencies use the CRA assessment factors in order to provide a rating to the
financial institution. The four point rating scale ranges from a high of
"outstanding" to a low of "substantial noncompliance."

The Equal Credit Opportunity Act (ECOA) generally prohibits discrimination in
any credit transaction, whether for consumer or business purposes, on the
basis of race, color, religion, national origin, sex, marital status, age
(except in limited circumstances), receipt of income from public assistance
programs, or good faith exercise of any rights under the Consumer Credit
Protection Act. The Truth in Lending Act (TILA) is designed to ensure that
credit terms are disclosed in a meaningful way so that consumers may compare
credit terms more readily and knowledgeably. As a result of the TILA, all
creditors must use the same credit terminology to express rates and payments,
including the annual percentage rate, the finance charge, the amount
financed, the total of payments and the payment schedule, among other things.

The Fair Housing Act ("FH Act") regulates many practices, including making it
unlawful for any lender to discriminate in its housing-related lending
activities against any person because of race color, religion, national
origin, sex, handicap or familial status. A number of lending practices have
been found by the courts to be, or may be considered, illegal under the FH
Act, including some that are not specifically mentioned in the FH Act itself.
The Home Mortgage Disclosure Act (HMDA) grew out of public concern over
credit shortages in certain urban neighborhoods

9


and provides public information that will help show whether financial
institutions are serving the housing credit needs of the neighborhoods and
communities in which they are located. The HMDA also includes a "fair
lending" aspect that requires the collection and disclosure of data about
applicant and borrower characteristics as a way of identifying possible
discriminatory lending patterns and enforcing anti-discrimination statutes.

The Right To Financial Privacy Act (RFPA) imposes a new requirement for
financial institutions to provide new privacy protections to consumers.
Financial institutions must provide disclosures to consumers of its privacy
policy, and state the rights of consumers to direct their financial
institution not to share their nonpublic personal information with third
parties (opt out).

Finally, the Real Estate Settlement Procedures Act (RESPA) requires lenders
to provide borrowers with disclosures regarding the nature and cost of real
estate settlements. Also, RESPA prohibits certain abusive practices, such as
kickbacks, and places limitations on the amount of escrow accounts.

Penalties under the above laws may include fines, reimbursement and other
penalties. Due to heightened regulatory concern related to compliance with
CRA, TILA, FH Act, ECOA, HMDA, RFPA and RESPA generally, Western Sierra may
incur additional compliance costs or be required to expend additional funds
for investments in its local community.

RECENT ACCOUNTING PRONOUNCEMENTS. In June 1998, the Financial Accounting
Standards Board (FASB) issued Statement of Financial Accounting Standards
(SFAS) 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITY, which
was subsequently amended in June 1999 by SFAS 137 and in June 2000 by SFAS
138. SFAS 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. It requires that entities recognize
all derivatives as either assets or liabilities in the balance sheet and
measure those instruments at fair value. SFAS 137 deferred the required
adoption date to fiscal quarters of all fiscal years beginning after June 15,
2000. SFAS 138 addressed certain issues causing difficulties in implementing
SFAS 133. Western Sierra adopted these statements on January 1, 2001 and, in
management's opinion, the implementation of these pronouncements is not
expected to have a material effect on the future consolidated financial
statements.

In September 2000, the FASB issued SFAS 140, ACCOUNTING FOR TRANSFERS AND
SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF LIABILITIES, to replace
SFAS 125 which was issued in June 1996. The original statement addresses
issues related to transfers of financial assets in which the transferor has
some continuing involvement with the transferred assets or with the
transferee. SFAS 140 resolves implementation issues which arose as a result
of SFAS 125, but carries forward most of the provisions of the original
statement. SFAS 140 is effective for transfers occurring after March 31, 2001
and for disclosures relating to securitization transactions and collateral
for fiscal years ending after December 15, 2000. Management does not believe
the adoption of this statement will have a significant impact on its
financial statements.

The Financial Standards Accounting Board released for comment on February 14,
2001, a revised proposal for the elimination of "pooling of interests"
accounting. The FASB indicated that it would accept comments through March
16, 2001. As proposed, it is currently anticipated that the FASB will issue a
final statement in June 2001, which would likely require, among other
matters, that all mergers initiated after the issuance of the final statement
be accounted for as "purchase" transactions. As proposed, a merger or
business combination would be considered initiated if the major terms of the
transaction, including the exchange or conversion ratio, are publicly
announced or otherwise disclosed to shareholders of the combining companies.
The revised proposal contemplates that goodwill will not be amortized to
earnings as originally proposed. Instead, goodwill would be recognized as an
asset in the financial statements, measured as the excess of the cost of an
acquired entity over the net of the amounts assigned to identifiable assets
acquired and liabilities assumed, and then tested for impairment to assess
losses and expensed against earnings only in the periods in which the
recorded value of goodwill exceeded its implied fair value, based on
standards to be specified in the final statement. The effect of the proposal
upon bank mergers is uncertain, however, the goodwill in a purchase
accounting transaction may not be included in the calculation of regulatory
capital requirements and some investment bankers have expressed the view that
the elimination of "pooling of interests" accounting will result in lower
merger premiums for sellers with the possibility of fewer transactions
occurring after the effective date of the final statement.

10


OTHER. Other legislation which has been or may be proposed to the United
States Congress and the California Legislature and regulations which may be
proposed by the FDIC and the DFI may affect the business of Western Sierra.
It cannot be predicted whether any pending or proposed legislation or
regulations will be adopted or the effect such legislation or regulations may
have upon the business or Western Sierra.

OTHER INFORMATION CONCERNING WESTERN SIERRA. Western Sierra holds no material
patents, trademarks, licenses, franchises or concessions.

No expenditures were made by Western Sierra since inception on material
research activities relating to the development of services or the
improvement of existing services. Based upon present business activities,
compliance with federal, state and local provisions regulating discharge of
materials into the environment will have no material effects upon the capital
expenditures, earnings and competitive position of Western Sierra.

ITEM 2. PROPERTIES

Western Sierra owns six depository branches and leases twelve other locations
used in the normal course of business located throughout Western Sierra's
service areas. There are no contingent rental payments and Western Sierra has
two sublease arrangements. Total rental expenses under all leases, including
premises, totaled $381,000, $361,000 and $376,000, in 2000, 1999 and 1998
respectively. The expiration dates of the leases vary, with the first such
lease expiring during 2001 and the last such lease expiring during 2007.
Western Sierra maintains insurance coverage on its premises, leaseholds and
equipment, including business interruption and record reconstruction coverage.

ITEM 3. LEGAL PROCEEDINGS

From time to time, Western Sierra and/or its subsidiary banks are a party to
claims and legal proceedings arising in the ordinary course of business.
Western Sierra's management is not aware of any material pending litigation
proceedings to which either it or any of its subsidiary banks is a party or
has recently been a party, which will have a material adverse effect on the
financial condition or results of operations of Western Sierra taken as a
whole.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matters were submitted to vote of the security holders during the fourth
quarter of the period covered by this report.

Under applicable Federal laws, the Comptroller restricts the total dividend
payment of any national banking association in any calendar year to the net
income of the year, as defined, combined with the net income for the two
preceding years, less distributions made to shareholders during the same
three-year period. In addition, the California Financial Code restricts the
total dividend payment of any State banking association in any calendar year
to the lesser of (1) the bank's retained earnings or (2) the bank's net
income for its last three fiscal years, less distributions made to
shareholders during the same three-year period. At December 31, 2000, the
subsidiaries had $7,754,371 in retained earnings available for dividend
payments to Western Sierra.

Western Sierra' primary source of revenue to pay dividends to its
shareholders is dividends from its subsidiaries. The amount and payment of
dividends by Western Sierra is set by Western Sierra's Board of Directors.
Any further dividends will be decided based on a number of factors including
results of operations, general business conditions, capital requirements,
general financial conditions, and other factors deemed relevant by the Board
of Directors.

Prior to the merger with Western Sierra, Sentinel Community Bank paid a $.34
per share cash dividend to shareholders of record as of 12/31/99. The
dividend was paid on Jan 6, 2000 and totaled $483,529.

ITEM 7. MANAGEMENT'S DISCUSSION & ANALYSIS

GENERAL. The Board of Directors and Management of Western Sierra believe that
the Company plays an important role in the economic well being of the
communities it serves. Its Subsidiary banks have a continuing responsibility
to provide a wide range of lending and deposit services to both individuals
and businesses. These services are tailored to meet the needs of the
communities served by Western Sierra and its subsidiary banks.

Various loan products are offered which promote home ownership and affordable
housing, fuel job growth and support community economic development. Types of
loans offered range from personal and commercial loans to real estate,
construction, agricultural, and mortgage loans. Banking decisions are made
locally and the goal is customer satisfaction.

Various deposit products are offered which are geared to provide both
individual and business customers with a wide range of choices. These
products include both high and low volume transaction accounts, savings and
money market products, certificate of deposit accounts with a wide range of
maturities, and IRA accounts including Roth and Educational IRAs as well.

Western Sierra remains committed to its shareholders and will continue its
efforts in 2001 to increase shareholder value. During 1999, the Company
became a member of NASDAQ and began trading on the NASDAQ exchange. As a
result, there has been increased liquidity in the Company's stock. During
2000, Management worked closely with its market makers and expanded the
information provided in the quarterly shareholder newsletter. The Company did
receive a "Buy" rating from Hoefer & Arnett early in the year. Management is
aware of the adverse stock market conditions over the past year, and the fact
that Western Sierra is still a relatively small and unnoticed Company. In
2001, Management will continue to spend time with both its market makers, and
others who can help increase the visibility of the Company, its earnings and
projections.

The following discussion is designed to provide a better understanding of
significant trends related to Western Sierra's financial condition, results
of operations, liquidity, capital resources and interest rate sensitivity. It
should be read in conjunction with Western Sierra's audited financial
statements and notes thereto and the other financial information appearing
elsewhere herein.

The following discussion pertains to Western Sierra's financial condition,
changes in financial condition and results of operations as of December 31,
2000 and 1999 and for each of the three years in the period ended December
31, 2000. The consolidated financial statements of Western Sierra include the
financial position and results of operations of Roseville 1st Community
Bancorp, Lake Community Bank and Sentinel Community Bank both before and
after their respective mergers with Western Sierra as a result of applying
the pooling-of-interests method of accounting for each transaction. The
discussion should be read in conjunction with Western


14


Sierra's audited consolidated financial statements and notes thereto and the
other financial information appearing elsewhere herein.

FINANCIAL CONDITION

2000 COMPARED TO 1999

The Company experienced another year of growth and expansion in 2000. Total
assets at December 31, 2000 were $474.6 million, an increase of $82.7
million, or 21%, over total assets of $391.9 million at December 31,1999.
Loans were $329.2 million, an increase of $54.9 million or 20%, over total
loans of $274.3 million at December 31, 1999. Loan growth was the result of
continued marketing efforts, strong economic conditions and the increased
lending opportunities and additional market areas resulting from the mergers
of Roseville 1st National Bank, Lake Community bank and Sentinel Community
Bank. In addition Western Sierra occasionally purchased pools of loans in
order to further diversify the portfolio and maximize profitability.

Total deposits at December 31, 2000 were $433.8 million, an increase of $90.6
million, or 26.4%, over total deposits of $343.2 million at December 31,
1999. Most of the deposit growth occurred in time deposits of $100,000 or
more, an increase of 59% to $86.4 million at December 31, 2000. NOW accounts
increased 26% to $52.8 million at December 31, 2000 and other time deposits
increased 28% to $139.8 million at December 31, 2000. The majority of Western
Sierra's deposits remain local core deposits. Lake Community Bank does
occasionally fund its loan growth with non-local certificates of deposit.

Total shareholders' equity at December 31, 2000 was $36.1 million, an
increase of $5.2 million over total shareholders' equity of $30.9 million at
December 31, 1999. The increase in equity is due to an increase in retained
earnings of $3.8 million for the twelve months ended December 31, 2000 and
the exercise of stock options by employees and directors, which was partially
offset by the repurchase of 29,165 shares of Western Sierra common stock
during 2000.

1999 COMPARED TO 1998

The total assets at December 31, 1999 were $391.9 million, an increase of
$9.3 million or 2.4% over total assets of $382.5 million at December 31,
1998. Loans were $274.4 million, an increase of $59.0 million or 27% over
total loans of $215.4 million at December 31, 1998.

Total deposits at December 31, 1999 were $343.2 million, almost even with
total deposits of $343.4 million at December 31, 1998. Non-interest bearing
deposits decreased 8% to $71.6 million at December 31, 1999, while interest
bearing deposits increased 2.5% to $271.6 million at December 31, 1999, for a
net decrease of $300,000 in total deposits for the year 1999.

Total shareholders' equity at December 31, 1999 was $30.9 million, an
increase of $1.6 million over total shareholders' equity of $29.3 million at
December 31, 1998. The increase in equity was due to an increase in retained
earnings of $3.3 million for the twelve months ended December 31, 1999 and
the exercise of stock options by employees and directors, and a change in the
unrealized loss on available-for-sale securities in 1999.

RESULTS OF OPERATIONS

NET INCOME. Western Sierra recorded net income of $3.9 million, or $1.12
diluted earnings per share, for the year ended December 31, 2000 compared to
net income of $3.3 million, or $.95 diluted earnings per share, in 1999 and
net income of $1.7 million, or $.51 diluted earnings per share, in 1998.

The increase in net income for each year above is generally attributed to
increases net interest income resulting from increases in earning assets,
lower provisions for loan losses attributable to improved credit quality, and
operating efficiencies.

NET INTEREST INCOME AND NET INTEREST MARGIN

Total interest income increased from $26.9 million in 1998 to $28.5 million
in 1999, and to $34.0 million in 2000, representing a 6.0% increase in 1999
over 1998 and a 19.3% increase in 2000 over 1999. The total interest income
increases in the periods discussed were primarily the result of growth in
Western Sierra's established market areas. Total interest expense decreased
from $11.0 million in 1998 to $10.9 million in 1999, and increased to $14.6
million in 2000, representing a 0.9% decrease in 1999 from 1998, and a 33.9%
increase in 2000 over 1999. The minimal decrease in interest expense from
1998 to 1999 was due to slightly lower interest rates across all deposit
types. The increase in interest expense in 2000 from 1999 was due to both
increased deposits and an increasing interest rate environment.

Western Sierra's net interest margin was 5.06% in 1998, 5.10% in 1999 and
4.98% in 2000. The change from 1998 to 1999 was a result of a lower yield on
earning assets combined with an almost equal lower yield in interest expense.
In 2000, Western Sierra felt its net interest margin tighten with competition
keeping earning asset yields from increasing at the same pace as rates for
time deposits during the same period.

The following table presents for the years indicated the distribution of
consolidated average assets, liabilities and shareholders' equity, as well as
the total dollar amounts of interest income from average earning assets and
the resultant yields, and the dollar amounts of interest expense and average
interest-bearing liabilities, expressed both in dollars and in rates.
Nonaccrual loans, which are not considered material, are included in the
calculation of the average balances of loans which interest not accrued is
excluded. Savings deposits include NOW and money market accounts.

The decrease in 1999 and 2000 from 1998 was primarily the result of a slower
market for home mortgages due to increasing interest rates. Western Sierra
will continue to implement strategies to increase its non-interest income to
help offset the decreasing interest margins the industry is experiencing.

NON-INTEREST EXPENSE. Non-interest expense amounted to $16.6 million in 2000,
$15.4 million in 1999 and $16.6 million in 1998. This represents a slight
increase of $1.2 million, or 7.8%, in 2000 and a decrease of $1.2 million, or
7%, in 1999 when compared to 1998.

Western Sierra continues to believe that to be able to compete in the current
environment of decreasing interest margins and increased competition, the
controlling of operating expenses is essential. The consolidation of many
operational functions in addition to other areas such as supplies, forms,
advertising and marketing was completed in 1999. This had a positive impact
on the Company's overhead and efficiency ratios. During 2000, additional
accounting and data processing responsibilities were combined to further
enhance the operating efficiencies of the organization. Management will
continue to closely monitor this area.

for the years ended December 31, 2000, 1999 and 1998.

PROVISION FOR LOAN AND LEASE LOSSES. The provision for loan and lease losses
corresponds directly to the level of the allowance that management deems
sufficient to offset potential losses. The balance in the allowance reflects
the amount which, in management's judgement, is adequate to provide for these
potential losses after weighing the mix of the loan portfolio, current
economic conditions, past loan experience and such other factors as deserve
recognition in estimating loan and lease losses.

Management allocated $380,000 as a provision for loan and lease losses in
2000, $920,000 in 1999 and $1.0 million in 1998. Loan recoveries net of
charge-offs in 2000 were $221,000. In 1999, loan charge-offs net of
recoveries were $114,000, and in 1998 were $1.0 million. The ratio of the
allowance for loan and lease losses to total gross loans was 1.33% in 2000,
1.38% in 1999, and 1.39% in 1998.

In management's opinion, the balance of the allowance for loan losses at
December 31, 2000 was sufficient to sustain any foreseeable losses in the
loan portfolio at that time. However, no assurances can be given that Western
Sierra will not sustain substantially higher loan and lease losses.

INCOME TAXES. Income taxes were $2.3 million in 2000, $1.6 million in 1999
and $875,000 in 1998, representing effective tax rates of 37.5%, 32.6% and
34.0%, respectively.

LIQUIDITY. A Funds Management Policy has been developed by Western Sierra's
management and approved by Western Sierra's Board of Directors which
establishes guidelines for the investments and liquidity of Western Sierra.
The goals of this policy are to provide liquidity to meet the financial
requirements of Western Sierra's customers, maintain adequate reserves as
required by regulatory agencies and maximize earnings of Western Sierra.
Liquidity of Western Sierra at December 31, 2000 was 19.8%, at December 31,
1999 was 15.5% and at December 31, 1998 was 36.8% 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.
Western Sierra's management believes it maintains adequate liquidity levels.

INVESTMENT PORTFOLIO. Western Sierra classifies its investment securities as
trading, held to maturity or available for sale. Western Sierra's intent is
to hold all securities classified as held to maturity until maturity and
management believes that it has the ability to do so. Securities available
for sale may be sold to implement Western Sierra asset/liability management
strategies and in response to changes in interest rates, prepayment rates and
similar factors.

The following table summarizes the maturities of Western Sierra's securities
at their carrying value and their weighted average yields at December 31,
2000. Yields on tax-exempt securities have not been computed on a

LOAN PORTFOLIO. Western Sierra experienced a 44.8% increase in loan
production during 2000 over 1999. Despite this record increase in loan
volume, portfolio quality remained uncompromised as evidenced by criticized
assets (including ORE) at 14.59% of capital and delinquencies as a percentage
of total loans at .16% for Western Sierra National Bank and .002% for Lake
Community Bank. The majority of Western Sierra's criticized assets were
acquired in the merger with Sentinel Community Bank. Without the merger, this
ratio would have been considerably lower. The reduction of the classified
assets acquired in the Sentinel merger will be a high priority for 2001.

Western Sierra's largest historical lending categories are real estate loans
and commercial loans. These categories accounted for approximately 83.9% and
13.0% respectively of Western Sierra's total loan portfolio at December 31,
2000, and approximately 72.6% and 19.3% respectively of Western Sierra's
total loan portfolio at December 31,1999. Loans are carried at face amount,
less payments collected and the allowance for possible loan losses. Interest
on all loans is accrued


22


monthly on a simple interest basis. Typically, once a loan is placed on
nonaccrual status, Western Sierra reverses interest accrued through the date
of the transfer. Loans are placed on nonaccrual status when principal or
interest on a loan is past due 90 days or more, unless the loan is both
well-secured and in the process of collection. Interest actually received for
loans on nonaccrual status is recognized as income at the time of receipt for
loans for which the ultimate collectibility of principal is not in doubt.
Problem loans are maintained on accrual status only when management of
Western Sierra is confident of full repayment within a reasonable period of
time.

The rates of interest charged on variable rate loans are set at specific
increments in relation to Western Sierra's published lending rate and vary as
Western Sierra's lending rate varies. At December 31, 2000, approximately
53.1% of Western Sierra's loan portfolio was compromised of variable rate
loans, and at December 31, 1999, approximately 50.2% of Western Sierra's loan
portfolio was compromised of variable interest rate loans.

The following table sets forth the amounts of loans outstanding by category
as of the dates indicated.

=================================================================


While Real Estate and Commercial remain the foundation of Western Sierra's
historical lending mix, some changes in the mix have occurred due to the
changing economic environment and the resulting change in demand for certain
loan types. While Western Sierra remains committed to the agricultural
industry in Lake County, there was a decrease in agricultural loan
outstandings to $5.0 million at December 31, 2000 from $15.4 million at
December 31, 1999. This decrease was a result of agricultural loan pay-offs
and fewer renewals and extensions at this time. Some of these credits were
problem credits which were carefully and diligently worked through, adding
more stringent financial requirements for any renewals or extensions, thus
significantly improving the overall loan portfolio quality.


23


COMMERCIAL LOANS. Commercial loans are made for the purpose of providing
working capital, financing the purchase of equipment or inventory and for
other business purposes. Such loans include loans with maturities ranging
from 30 to 360 days and term loans, which are loans with maturities normally
ranging from one to five years. Short-term business loans are generally used
to finance current transactions and typically provide for periodic interest
payment, with principal being payable at maturity or periodically. Term loans
normally provide for monthly payments of both principal and interest.

Western Sierra extends lines of credit to business customers. On business
credit lines, Western Sierra specifies a maximum amount which it stands ready
to lend to the customer during a specified period in return for which the
customer agrees to maintain its primary banking relationship with Western
Sierra. The purpose for which such loans will be used and the security
pledged, if any, are determined before Western Sierra's commitment is
extended. Normally Western Sierra does not make credit line commitments in
material amounts for periods in excess of one year.

REAL ESTATE LOANS. Real Estate loans are primarily made for the purpose of
purchasing, refinancing, improving or constructing family residences as well
as commercial and industrial properties.

At December 31, 2000, approximately 58.8% of Western Sierra's single family
real estate construction loans consisted of loans secured by first trust
deeds on the construction of owner-occupied single family dwellings, and the
remaining 41.1% consisted of loans secured by first deeds on speculative
single family dwellings. Construction loans are generally written with terms
of six to twelve months and usually do not exceed a loan to appraised value
ratio of 75 to 80%. The risk associated with speculative construction lending
includes the borrower's inability to complete and sell the project, the
borrower's incorrect estimate of necessary construction funds and/or time for
completion and economic changes, including depressed real estate values and
increased interest rates. Management has established underwriting criteria to
minimize losses on speculative construction loans by lending only to
experienced developers and contractors with proven track records. To date
Western Sierra has not suffered any significant losses through its
speculative real estate construction loans.

LOAN COMMITMENTS. In the normal course of business, there are various
commitments outstanding to extend credit that are not reflected in the
financial statements. Annual review of commercial credit lines and ongoing
monitoring of outstanding balances reduces the risk of loss associated with
these commitments. As of December 31, 2000, Western Sierra had $59.2 million
in unfunded commercial real estate loan commitments which are secured by real
estate and $25.6 million in unfunded commercial commitments unsecured by real
estate. In addition, Western Sierra had $16.2 million in other unused
commitments. The Company's undisbursed commercial loan commitments represent
primarily business lines of credit. The undisbursed construction commitments
represented undisbursed funding on construction projects in process. The
mortgage loan commitments represented approved but unfunded mortgage loans
with Western Sierra's mortgage banking business.

24


Based upon prior experience and prevailing economic conditions, it is
anticipated that approximately 60% of the commitments at December 31, 2000
will be exercised during 2001.

MATURITY DISTRIBUTION. The following table sets forth of loans outstanding of
Western Sierra as of December 31, 2000 which based on the remaining scheduled

ASSET QUALITY. Western Sierra attempts to minimize credit risk through its
underwriting and credit review policies. The Company conducts its own
internal credit review processes. The Board of Directors through the loan
committee, reviews the asset quality of new and problem loans on a monthly
basis and reports the findings to the full Board. In management's opinion,
this loan review system facilitates the early identification of potential
problem loans.

With respect to Western Sierra's policy of placing loans 90 days or more
past due on nonaccrual status unless the loan is well secured and in the
process of collection. A loan is considered to be in the process of
collection if, based on a probable specific event, it is expected that the
loan will be repaid or brought current. Generally, this collection period
would not exceed 90 days. When a loan is placed on nonaccrual status Western
Sierra's general policy is to reverse and charge against current income
previously accrued but unpaid interest. Interest income on such loans is
subsequently recognized only to the extent that cash is received and future
collection of principal is deemed by management to be probable. Where the
collectibility of the principal of or interest on a loan is considered to be
doubtful by management, it is placed on nonaccrual status prior to becoming
90 days delinquent.

Interest income is recognized on impaired loans in a manner similar to that
of all loans. It is Western Sierra's policy to place loans that are
delinquent 90 days or more as to principal or interest on nonaccrual status
unless secured and in the process of collection and to reverse from current
income accrued but uncollected interest. Cash payments subsequently received
on nonaccrual loans are recognized as income only where the future collection
of principal is considered by management to be probable.

Allowance for loan and leases losses
to nonperforming loans 392.06 698.71 177.54 88.70 71.25



27


The allowance for loan and lease losses is established through charges to
earnings in the form of the provision for loan and lease losses. Loan and
lease losses are charged to and recoveries are credited to the allowance for
loan and lease losses. The provision for loan and lease losses is determined
after considering various factors such as loan and lease loss experience,
current economic conditions, maturity of the portfolio, size of the
portfolio, industry concentrations, borrower credit history, the existing
allowance for loan and lease losses, independent loan reviews, current
charges and recoveries to the allowance for loan and lease losses and the
overall quality of the portfolio as determined by management, regulatory
agencies, and independent credit review consultants retained by Western
Sierra.

The adequacy of Western Sierra's allowance for loan loss reserve is based on
specific and formula allocations to Western Sierra's loan portfolio. Specific
allocations are made for identified problem or potential problem loans. The
specific allocations are increased or decreased through management's
reevaluation of the status of the particular problem loans. Loans which do
not receive a specific allocation receive an allowance allocation based on a
formula represented by a percentage factor based on underlying collateral,
type of loan, historical charge-offs and general economic conditions which is
applied against the general portfolio segments.

It is the policy of management to make additions to the allowance for loan
and lease losses so that it remains adequate to cover anticipated charge-offs
and management believes that the allowance at December 31, 2000 is adequate.
However, the determination of the amount of the allowance is judgmental and
subject to economic conditions which cannot be predicted with certainty.
Accordingly, Western Sierra cannot predict whether charge-offs of loans in
excess of the allowance may be required in future periods.

The provision for loan and lease losses reflects an accrual sufficient to
cover projected probable charge-offs and the maintenance of the allowance at
a level deemed adequate to absorb potential future losses.

The table below sets forth the allocation of the allowance for loan and lease
losses by loan type as of the dates specified. The allocation of individual
categories of loans includes amounts applicable to specifically identified as
well as unidentified losses inherent in that segment of the portfolio and
will necessarily change whenever management determines that the risk
characteristics of the portfolio have changed.

28


Management believes that any breakdown or allocation of the allowance for
loan and lease losses into loan categories lends an appearance of exactness
which does not exist, in that the allowance is utilized as a single
unallocated allowance available for all loans and undisbursed commitments.
The allocation below should not be interpreted as an indication of the
specific amounts or loan categories in which future charge-offs may occur:

DEPOSIT STRUCTURE. Deposits represent Western Sierra's primary source of
funds. Deposits are primarily core deposits in that they are demand, savings
and time deposits generated from local businesses and individuals. These
sources are considered to be relatively stable, long-term relationships
thereby enhancing steady growth of the deposit base without major
fluctuations in overall deposit balances. Western Sierra experiences to a
small degree some seasonality with slower growth period between November
through April, and the higher growth period from May through October. In
order to assist in meeting any funding demands, Western Sierra maintains
unsecured borrowing arrangements with several correspondent banks in addition
to a secured borrowing arrangement with the Federal Home Loan Bank for longer
more permanent funding needs.

The following chart sets forth the distribution of Western Sierra's average
daily deposits for the periods indicated.

Time deposits of $100,000 or more are generally from Western Sierra's local
business and individual customer base. The potential impact on Western
Sierra's liquidity from the withdrawal of these deposits is discussed in
Western Sierra's asset and liability management committee, and is considered
to be minimal.

OTHER BORROWINGS. Western Sierra's short-term borrowing arrangements are
discussed in detail in note 8 to the financial statements.

The following table summarizes the balances outstanding at year end, the
highest amount of borrowings outstanding for a month-end during the year, the
average balance of borrowings and the weighted average rate for the years
ended December 31, 2000, 1999 and 1998

Maximum Amount at any Month End $13,817 $15,300 $ 6,150
Average Interest Rate 6.02% 4.95% 5.12%


TERMS. The terms of the short-term borrowings over this three year period
varied, consisting of the following:

1) Overnight Federal Funds purchased

2) Three and six month term borrowings under a blanket lien agreement
with FHLB, with Mortgage loans as collateral

3) Line of credit advances with FHLB, with securities as collateral

The majority of the borrowings were on behalf of Sentinel Community Bank
prior to the merger, which as a savings institution, depended more heavily on
this as a source of funds than does Western Sierra. Therefore this trend is
expected to decline substantially in the future.

ITEM 7a. QUANTITATIVE & QUALITATIVE DISCLOSURE ABOUT MARKET RISK

As a financial institution, Western Sierra'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 Banks' 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. Since virtually all of Western Sierra's
interest earning assets and all of Western Sierra's interest bearing
liabilities are located at the Bank level, virtually all of Western Sierra's
interest rate risk exposure lies at the Bank level. As a result, all
significant interest rate risk management procedures are performed at the
Bank level. Based upon the nature of their operations, the Banks are not
subject to foreign currency exchange or commodity price risk. The Banks' real
estate loan portfolios, concentrated primarily within northern California,
are subject to risks associated with the local economies.

The fundamental objective of Western Sierra's management of its assets and
liabilities is to maximize its 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 Banks' profitability is dependent to a
large extent upon their net interest income which is the difference between
their interest income on interest-earning assets, such as loans and
securities, and their interest expense on interest-bearing liabilities, such
as deposits and borrowings. The Banks, like other financial institutions, are
subject to interest rate risk to the degree that their interest-earning
assets reprice differently than their interest-bearing liabilities. The Banks
manage their mix of assets and liabilities with the goals of limiting their
exposure to interest rate risk, ensuring adequate liquidity, and coordinating
their sources and uses of funds.

The Banks seek to control their 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 Banks have adopted formal policies
and practices to monitor and manage interest rate risk exposure. As part of
this effort, the Banks will measure interest rate risk utilizing both an
internal ALMII module which runs on the mainframe computer system and
utilizing third party sources which can be compared and analyzed enabling
management to make any adjustments as necessary.

The following table sets forth as of December 31, 2000, the distribution of
repricing opportunities for Western Sierra's earning assets and
interest-bearing liabilities, the interest rate sensitivity gap, the
cumulative interest rate sensitivity gap, the interest rate sensitivity gap
ratio (i.e. earning assets divided by interest-bearing liabilities) and the
cumulative interest rate sensitivity gap ratio.

The opportunity to reprice assets in the same dollar amounts and at the same
time as liabilities would minimize interest rate risk in any interest rate
environment. The difference between the amounts of assets and liabilities
repriced at the same time, or "gap", represents the risk, or opportunity, in
repricing. In general, if more assets than liabilities are repriced at a
given time in a rising rate environment net interest income would improve
while in a declining rate environment net interest income would decline. If
more liabilities than assets were repriced under the same conditions the
opposite would result. Western Sierra appears liability sensitive in the
immediate to six month area, and turns asset sensitive in the longer term.
This can be and is influenced by the fact that interest-bearing transaction
accounts which consist of money market, NOW and savings deposit accounts are
classified as repricing within three months when in fact these deposits may
be immediately repriced at management's option, thus assisting in the further
management of interest rate risk. Western Sierra lists these deposits as it
has because this is the actual historical trend Western Sierra has
experienced.

CAPITAL STANDARDS. The federal banking agencies have risk-based capital
adequacy guidelines intended to provide a measure of capital adequacy that
reflects the degree of risk associated with a banking organization's
operations for both transactions reported on the balance sheet as assets and
transactions such as letters of credit and recourse arrangements, which are
recorded as off balance sheet items. Under these guidelines, nominal dollar
amounts of assets and credit equivalent amounts of off balance sheet items
are multiplied by one of several risk adjustment percentages, which range
from 0% for assets with low credit risk, such as certain U.S. government
securities, to 100% for assets with relatively higher credit risk, such as
certain loans.

As of December 31, 2000, Western Sierra's capital ratios exceeded applicable
regulatory requirements. The following tables present the capital ratios for
Western Sierra and the Banks compared to the standards for well-capitalized
bank holding companies and depository institutions as of December 31, 2000
(amounts in thousands except percentage amounts).

The current and projected capital positions of the Company and its Banks and
the impact of capital plans and long-term strategies are reviewed regularly
by management. Western Sierra's policy is to maintain ratios above the
prescribed well-capitalized ratios at all times. Management believes as of
December 31, 2000, that Western Sierra exceeds all capital adequacy
requirements to which it is subject.

Sierra Bancorp and subsidiaries (the "Company") as of December 31, 2000 and 1999
and the related consolidated statements of income, changes in shareholders'
equity and cash flows for each of the years in the three-year period ended
December 31, 2000. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits. We did
not audit the balance sheet of Sentinel Community Bank as of December 31, 1999,
or the related statements of income, changes in shareholders' equity and cash
flows for each of the years in the two-year period ended December 31, 1999,
which statements reflect total assets of $92,623,000 as of December 31, 1999,
and net earnings of $503,000 and $601,000 for the years ended December 31, 1999
and 1998, respectively. Those statements were audited by other auditors whose
reports have been furnished to us, and our opinion, insofar as it relates to the
amounts included for Sentinel Community Bank for 1999 and 1998, is based solely
upon the reports of the other auditors.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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, based upon our audits and the reports of other
auditors, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Western
Sierra Bancorp and subsidiaries as of December 31, 2000 and 1999, and the
consolidated results of their operations and their cash flows for each of the
years in the three-year period ended December 31, 2000, in conformity with
generally accepted accounting principles.

The consolidated financial statements as of December 31, 2000 and 1999
and for each of the years in the three-year period ended December 31, 2000 have
been restated to reflect the pooling of interests with Lake Community Bank,
Roseville 1st Community Bancorp and Sentinel Community Bank as described in Note
2 to the consolidated financial statements.

WESTERN SIERRA BANCORP AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

GENERAL

Western Sierra Bancorp (the "Company") was incorporated on July 11,
1996, and subsequently obtained approval from the Board of Governors of
the Federal Reserve System to be a bank holding company. On December
31, 1996, Western Sierra National Bank (WSNB) consummated a merger with
Western Sierra Bancorp. On April 30, 1999, the Company consummated
mergers with Roseville 1st Community Bancorp (R1CB) and Lake Community
Bank (LCB). On May 5, 2000, R1NB merged into WSNB and ceased to exist
as a separate entity. On May 31, 2000, the Company completed its
acquisition of Sentinel Community Bank (SCB) through the merger of SCB
with and into WSNB. The mergers qualified as tax-free exchanges and
were accounted for under the pooling-of-interests method of accounting.
Information concerning common stock, stock option plans and per share
data has been restated on an equivalent share basis. WSNB and LCB (the
"subsidiaries") engage in consumer, commercial and agricultural
banking, offering a wide range of products and services to individuals
and businesses in El Dorado, Placer, Sacramento, Lake, Tuolumne and
Sonora counties.

The accounting and reporting policies of the Company and its
subsidiaries conform with generally accepted accounting principles and
prevailing practices within the financial services industry.

RECLASSIFICATIONS

Certain reclassifications have been made to prior years' balances to
conform to classifications used in 2000.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries. All material intercompany
transactions and accounts have been eliminated in consolidation.

INVESTMENT SECURITIES

Investments are classified into the following categories:

- Trading securities, reported at fair value, with unrealized
gains and losses included in earnings.

- Available-for-sale securities, reported at fair value, with
unrealized gains and losses excluded from earnings and
reported, net of taxes, as accumulated other comprehensive
income (loss) within shareholders' equity.

- Held-to-maturity securities, which management has the positive
intent and ability to hold, reported at amortized cost,
adjusted for the accretion of discounts and amortization of
premiums.

Management determines the appropriate classification of its investments
at the time of purchase and may only change the classification in
certain limited circumstances. All transfers between categories are
accounted for at fair value.

Gains or losses on the sale of investment securities are computed on
the specific identification method. Interest earned on investment
securities is reported in interest income, net of applicable
adjustments for accretion of discounts and amortization of premiums. In
addition, unrealized losses that are other than temporary are
recognized in earnings for all investments.

LOAN SALES AND SERVICING

Originated mortgage loans are either held in the loan portfolio or sold
in the secondary market. Loans held for sale are carried at the lower
of cost or market value. Market value is determined by the specific
identification method as of the balance sheet date or the date which
investors have committed to purchase the loans. At the time the loans
are sold, the related right to service the loans are either retained,
earning future servicing income, or released in exchange for a one-time
servicing-released premium. Mortgage loans subsequently transferred to
the loan portfolio are transferred at the lower of cost or market value
at the date of transfer. Any difference between the carrying amount of
the loan and its outstanding principal balance is recognized as an
adjustment to yield by the interest method. Loans serviced for others
totaled $20,962,000 and $26,099,000 as of December 31, 2000 and 1999,
respectively.

On December 21, 2000, the Company sold its rights to service the
above-mentioned loans to another financial institution and recognized a
pre-tax gain of $76,000. Cash proceeds of $58,000 were received upon
the close of escrow and a receivable of $134,000 was recorded. Under
the terms of the sales agreement, the Company will continue to service
these loans until March 2001.


F-7


WESTERN SIERRA BANCORP AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Continued)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

LOAN SALES AND SERVICING (Continued)

The guaranteed portion of certain Small Business Administration (SBA)
loans are sold to third parties with the unguaranteed portion retained.
A premium in excess of the adjusted carrying value of the loan is
generally recognized at the time of sale. A portion of this premium may
be required to be refunded if the borrower defaults or the loan prepays
within ninety days of the settlement date. However, there were no sales
of loans subject to these recourse provisions at December 31, 2000,
1999 or 1998. SBA loans with unpaid balances of $6,116,000 and
$4,324,000 were being serviced for others at December 31, 2000 and
1999, respectively.

Servicing rights acquired through 1) a purchase or 2) the origination
of loans which are sold or securitized with servicing rights retained
are recognized as separate assets or liabilities. Servicing assets or
liabilities are recorded at the difference between the contractual
servicing fees and adequate compensation for performing the servicing,
and are subsequently amortized in proportion to and over the period of
the related net servicing income or expense. Servicing assets are
periodically evaluated for impairment. Servicing rights were not
considered material for disclosure purposes.

In addition, commercial loans totaling $18,258,000 and $23,247,000 were
serviced for others as of December 31, 2000 and 1999, respectively.
These loans were sold without recourse and, therefore, their balances
are not included on the balance sheet.

LOANS AND LEASES

Loans and leases are stated at principal balances outstanding, except
for loans transferred from loans held for sale which are carried at the
lower of principal balance or market value at the date of transfer,
adjusted for accretion of discounts. Interest is accrued daily based
upon outstanding loan and lease balances. However, when, in the opinion
of management, loans and leases are considered to be impaired and the
future collectibility of interest and principal is in serious doubt,
loans and leases are placed on nonaccrual status and the accrual of
interest income is suspended. Any interest accrued but unpaid is
charged against income. Payments received are applied to reduce
principal to the extent necessary to ensure collection. Subsequent
payments on these loans and leases, or payments received on nonaccrual
loans and leases for which the ultimate collectibility of principal is
not in doubt, are applied first to earned but unpaid interest and then
to principal.

An impaired loan or lease is measured based on the present value of
expected future cash flows discounted at the instrument's effective
interest rate or, as a practical matter, at the instrument's observable
market price or the fair value of collateral if the loan or lease is
collateral dependent. A loan or lease is considered impaired when,
based on current information and events, it is probable that the
Company will be unable to collect all amounts due (including both
principal and interest) in accordance with the contractual terms of the
loan or lease agreement.

Loan and lease origination fees, commitment fees, direct loan and lease
origination costs and purchase premiums and discounts on loans and
leases are deferred and recognized as an adjustment of yield, to be
amortized to interest income over the contractual term of the loan or
lease. The unamortized balance of deferred fees and costs is reported
as a component of net loans and leases.

ALLOWANCE FOR LOAN AND LEASE LOSSES

The allowance for loan and lease losses is maintained to provide for
probable losses related to impaired loans and leases and other losses
on loans and leases identified by management as doubtful, substandard
and special mention, as well as losses that can be expected to occur in
the normal course of business. The determination of the allowance is
based on estimates made by management, to include consideration of the
character of the loan and lease portfolio, specifically identified
problem loans, potential losses inherent in the portfolio taken as a
whole and economic conditions in the Company's service area.

Loans and leases determined to be impaired or classified are
individually evaluated by management for specific risk of loss. In
addition, reserve factors are assigned to currently performing loans
and leases based on management's assessment of the following for each
identified loan and lease type: (1) inherent credit risk, (2)
historical losses and, (3) where the Company has not experienced
losses, the loss experience of peer banks. Management also computes
specific and expected loss reserves for loan and lease commitments.
These estimates are particularly susceptible to changes in the economic
environment and market conditions.

The Company's Loan Committee reviews the adequacy of the allowance for
loan and lease losses at least quarterly, to include consideration of
the relative risks in the portfolio and current economic conditions.
The allowance for loan and lease losses is adjusted based on that
review if, in the judgment of the Loan Committee and management,
changes are warranted.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

ALLOWANCE FOR LOAN AND LEASE LOSSES (Continued)

The allowance is established through a provision for loan and lease
losses which is charged to expense. Additions to the allowance for loan
and lease losses are expected to maintain the adequacy of the total
allowance for loan and lease losses after credit losses and loan and
lease growth. The allowance for loan and lease losses at December 31,
2000 and 1999, respectively, reflects management's estimate of losses
in the portfolio.

OTHER REAL ESTATE

Other real estate includes real estate acquired in full or partial
settlement of loan obligations. When property is acquired, any excess
of the recorded investment in the loan balance and accrued interest
income over the estimated fair market value of the property, net of
estimated selling costs, is charged against the allowance for loan and
lease losses. A valuation allowance for losses on other real estate is
maintained to provide for temporary declines in value. The allowance is
established through a provision for losses on other real estate which
is included in other expenses. Subsequent gains or losses on sales or
writedowns resulting from permanent impairments are recorded in other
income or expense as incurred. There was no other real estate held by
the Company at December 31, 2000. Other real estate held by the Company
at December 31, 1999 totaled $715,000 and was included on the
consolidated balance sheet in accrued interest income and other assets.

PREMISES AND EQUIPMENT

Premises and equipment are carried at cost. Depreciation is determined
using the straight-line method over the estimated useful lives of the
related assets. The useful lives of premises are estimated to be thirty
to forty years. The useful lives of furniture, fixtures and equipment
are estimated to be one to fifteen years. Leasehold improvements are
amortized over the life of the asset or the term of the related lease,
whichever is shorter. When assets are sold or otherwise disposed of,
the cost and related accumulated depreciation or amortization are
removed from the accounts, and any resulting gain or loss is recognized
in income for the period. The cost of maintenance and repairs is
charged to expense as incurred.

INCOME TAXES

The Company files its income taxes on a consolidated basis with its
subsidiaries. The allocation of income tax expense (benefit) represents
each entity's proportionate share of the consolidated provision for
income taxes.

Deferred tax assets and liabilities are recognized for the tax
consequences of temporary differences between the reported amounts of
assets and liabilities and their tax bases. Deferred tax assets and
liabilities are adjusted for the effects of changes in tax laws and
rates on the date of enactment. On the consolidated balance sheet, net
deferred tax assets are included in accrued interest receivable and
other assets.

CASH EQUIVALENTS

For the purpose of the consolidated statement of cash flows, cash and
due from banks and Federal funds sold are considered to be cash
equivalents. Generally, Federal funds are sold for one day periods.

EARNINGS PER SHARE

Basic earnings per share (EPS), which excludes dilution, is computed by
dividing income available to common shareholders 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. The treasury stock method has been applied to
determine the dilutive effect of stock options in computing diluted
EPS. Earnings per share is retroactively adjusted for stock dividends
for all periods presented. In addition, EPS has been restated on an
equivalent share basis for all periods presented in connection with the
mergers previously noted.

STOCK-BASED COMPENSATION

Stock options are accounted for under the intrinsic value method
prescribed in Accounting Principles Board Opinion No. 25, ACCOUNTING
FOR STOCK ISSUED TO EMPLOYEES. Accordingly, compensation cost for stock
options is measured as the excess, if any, of the quoted market price
of the Company's stock at the date of grant over the exercise price.
However, if the fair value of stock-based compensation computed under a
fair value based method, as prescribed in Statement of Financial
Accounting Standards No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION,
is material to the financial statements, pro forma net income and
earnings per share are disclosed as if the fair value method had been
applied.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

USE OF ESTIMATES

The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make
estimates and assumptions. These estimates and assumptions affect the
reported amounts of assets and liabilities at the date of the
consolidated financial statements and the reported amounts of revenues
and expenses during the reporting period. Actual results could differ
from these estimates.

NEW FINANCIAL ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) 133, ACCOUNTING FOR
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITY, which was subsequently
amended in June 1999 by SFAS 137 and in June 2000 by SFAS 138. SFAS 133
establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. It requires that entities
recognize all derivatives as either assets or liabilities in the
balance sheet and measure those instruments at fair value. SFAS 137
deferred the required adoption date to fiscal quarters of all fiscal
years beginning after June 15, 2000. SFAS 138 addresses certain issues
causing difficulties in implementing SFAS 133. The Company adopted
these statements on January 1, 2001 and, in management's opinion, the
implementation of these pronouncements is not expected to have a
material effect on the future consolidated financial statements.

In September 2000, the FASB issued SFAS 140, ACCOUNTING FOR TRANSFERS
AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF LIABILITIES,
to replace SFAS 125 which was issued in June 1996. The original
statement addressed issues related to transfers of financial assets in
which the transferor has some continuing involvement with the
transferred assets or with the transferee. SFAS 140 resolves
implementation issues which arose as a result of SFAS 125, but carries
forward most of the provisions of the original statement. SFAS 140 is
effective for transfers occurring after March 31, 2001 and for
disclosures relating to securitization transactions and collateral for
fiscal years ending after December 15, 2000. Management does not
believe the adoption of this statement will have a significant impact
on its financial statements.

2. MERGERS AND ACQUISITIONS

On May 31, 2000, the Company completed its acquisition of Sentinel
Community Bank (SCB) through the merger of SCB with and into the
Company's wholly owned subsidiary, Western Sierra National Bank. The
Company exchanged 721,132 shares of its common stock (after adjustment
for fractional shares) for all of the common stock of SCB. Each share
of SCB was exchanged for 1.491 shares of the Company. In addition, SCB
stock options were converted at the same exchange ratio into options to
purchase 110,934 shares of the Company's common stock.

The merger has been accounted for as a pooling of interests and,
accordingly, all prior period financial statements have been restated
to include the combined results of operations, financial position and
cash flows of the Company and SCB. Information concerning common stock,
stock option plans and per share data has been restated on an
equivalent share basis. In addition, the Company and SCB incurred
$1,057,000 in merger related costs which were charged to operations
during the year ended December 31, 2000.

There were no material transactions between the Company or its bank
subsidiaries and SCB prior to the merger, and the effects of conforming
the accounting policies of SCB to those of the Company were not
material.

Selected financial information for the combining entities included in
the consolidated statements of income for the five months ended May 31,
2000 (unaudited) and the two years ended December 31, 1999 and 1998 is

the years ended December 31, 1999 and 1998, respectively. Acquisition
related expenses of $47,000 were charged to operations during the year
ended December 31, 2000.

On April 30, 1999, the Company completed mergers with Lake Community
Bank (LCB) and Roseville 1st Community Bancorp (R1CB) by exchanging
856,597 and 387,486 shares, respectively, of its common stock (after
adjustment for fractional shares) for all the common stock of the two
entities. Each share of LCB and R1CB were exchanged for .6905 shares
and 1.211 shares, respectively, of the Company. In addition,
outstanding LCB and R1CB stock options were converted at the same
exchange ratios into options to purchase 67,391 and 66,643 shares,
respectively, of the Company's common stock. The mergers have been
accounted for as pooling of interests.

LEASES

The Company leases its administrative office and certain of its branch
offices under noncancelable operating leases. These leases expire on
various dates through 2004 and have various renewal options ranging
from five to ten years. Rental payments include minimum rentals, plus
adjustments for changing price indexes. Future minimum lease payments
are as follows (dollars in thousands):

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

The Company is a party to financial instruments with off-balance-sheet
risk in the normal course of business in order to meet the financing
needs of its customers and to reduce its exposure to fluctuations in
interest rates. These financial instruments include commitments to
extend credit and letters of credit. These instruments involve, to
varying degrees, elements of credit and interest rate risk in excess of
the amount recognized on the balance sheet.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK (Continued)

The Company's exposure to credit loss in the event of nonperformance by
the other party for commitments to extend credit and letters of credit
is represented by the contractual amount of those instruments. The
Company uses the same credit policies in making commitments and letters
of credit as they do for loans and leases included on the consolidated
balance sheet.

The following financial instruments represent off-balance-sheet credit
risk (dollars in thousands):

Letters of credit $ 2,574 $ 428
============= ===========


Real estate commitments are generally secured by property with
loan-to-value ratios not to exceed 80%. In addition, the majority of
the Company's commitments have variable interest rates.

Commitments to extend credit are agreements to lend to a customer as
long as there is no violation of any condition established in the
contract. Commitments generally have fixed expiration dates or other
termination clauses and may require payment of a fee. Since some of the
commitments are expected to expire without being drawn upon, the total
commitment amounts do not necessarily represent future cash
requirements. Each customer's creditworthiness is evaluated on a
case-by-case basis. The amount of collateral obtained, if deemed
necessary upon extension of credit, is based on management's credit
evaluation of the borrower. Collateral held varies, but may include
deposits, accounts receivable, inventory, equipment, income-producing
commercial properties and residential real estate.

Letters of credit are conditional commitments to guarantee the
performance or financial obligation of a customer to a third party. The
credit risk involved in issuing letters of credit is essentially the
same as that involved in extending loans to customers.

SIGNIFICANT CONCENTRATIONS OF CREDIT RISK

The Company grants real estate mortgage, real estate construction,
commercial, agricultural and consumer loans and leases to customers
throughout El Dorado, Placer, Sacramento, Lake, Tuolumne and Sonora
counties.

In management's judgment, a concentration exists in real estate-related
loans which represented approximately 84% and 72% of the Company's loan
portfolio at December 31, 2000 and 1999, respectively. Although
management believes such concentrations to have no more than the normal
risk of collectibility, a substantial decline in the economy in
general, or a decline in real estate values in the Company's primary
market areas in particular, could have an adverse impact on
collectibility of these loans. Personal and business income represent
the primary source of repayment for a majority of these loans and
leases.

In addition, a substantial portion of the loans and leases in the Lake
County area are dependent upon the agribusiness and resort and
recreational economic sectors.

9. COMMITMENTS AND CONTINGENCIES (Continued)

CONTINGENCIES

The Company is subject to legal proceedings and claims which arise in
the ordinary course of business. In the opinion of management, the
amount of ultimate liability with respect to such actions will not
materially affect the financial position or results of operations of
the Company.

FEDERAL RESERVE REQUIREMENT

Banks are required to maintain reserves with the Federal Reserve Bank
equal to the percentage of their reservable deposits. The reserve
balances held by the subsidiaries with the Federal Reserve Bank totaled
$1,631,000 and $1,625,000 at December 31, 2000 and 1999, respectively.

CORRESPONDENT BANKING AGREEMENTS

The Company maintains funds on deposit with other federally insured
institutions under correspondent banking agreements. Uninsured deposits
totaled $586,000 at December 31, 2000.

10. SHAREHOLDERS' EQUITY

DIVIDENDS

Upon declaration by the Board of Directors of the Company, all
shareholders of record will be entitled to receive dividends. Under
applicable Federal laws, the Comptroller of the Currency restricts the
total dividend payment of any national banking association in any
calendar year to the net income of the year, as defined, combined with
the net income for the two preceding years, less distributions made to
shareholders during the same three-year period. In addition, the
California Financial Code restricts the total dividend payment of any
State banking association in any calendar year to the lesser of (1) the
bank's retained earnings or (2) the bank's net income for its last
three fiscal years, less distributions made to shareholders during the
same three-year period. At December 31, 2000, the subsidiaries had
$7,754,000 in retained earnings available for dividend payments to the
Company.

EARNINGS PER SHARE (Continued)

Shares of common stock issuable under stock options for which the
exercise prices were greater than the average market prices were not
included in the computation of diluted earnings per share due to their
antidilutive effect. Stock options not included in the computation of
diluted earnings per share ranged from 17,392 during the first quarter
to 75,981 for the remainder of the year ended December 31, 2000. There
were no stock options excluded from the calculation of diluted earnings
per share in 1999 and 1998.

STOCK OPTIONS

In 1999, 1997, 1990 and 1989, the Board of Directors adopted stock
option plans for which 564,223 shares of common stock remain reserved
for issuance to employees and Directors under incentive and
nonstatutory agreements. The plans require that the option price may
not be less than the fair market value of the stock at the date the
option is granted, and that the stock must be paid in full at the time
the option is exercised. The options expire on a date determined by the
Board of Directors, but not later than ten years from the date of
grant. The vesting period is determined by the Board of Directors and
is generally over five years. Outstanding options under the 1997 and
1989 plans are exercisable until their expiration; however, no new
options will be granted under these plans.

The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards (SFAS) No. 123, ACCOUNTING FOR
STOCK-BASED COMPENSATION. Accordingly, no compensation expense has been
recognized for options granted under its stock option plan. Had
compensation cost for the plan been determined based on the fair value
at grant date for awards in 2000 and 1999 consistent with the
provisions of SFAS No. 123, the Company's net earnings and earnings per
share would have been reduced to the pro forma amounts indicated below.
Compensation expense is recognized in the years in which the options
become vested.

COMMON STOCK REPURCHASE PROGRAM

During 1999, the Board of Directors authorized the repurchase of up to
30,000 shares of the Company's common stock. Repurchases were generally
made in the open market at market prices. Substantially all shares
authorized under this plan have been repurchased as of December 31,
2000.

REGULATORY CAPITAL

The Company and its subsidiaries are subject to certain regulatory
capital requirements administered by the Board of Governors of the
Federal Reserve System, the Office of the Comptroller of the Currency
(OCC) and the Federal Deposit Insurance Corporation (FDIC). Failure to
meet these minimum capital requirements can initiate certain mandatory,
and possibly additional discretionary, actions by regulators that, if
undertaken, could have a direct material effect on the Company's
consolidated financial statements. Under capital adequacy guidelines
and the regulatory framework for prompt corrective action, the
subsidiaries must meet specific capital guidelines that involve
quantitative measures of their assets, liabilities and certain
off-balance-sheet items as calculated under regulatory accounting
practices. The Company's and its subsidiaries' capital amounts and
classification are also subject to qualitative judgments by the
regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital
adequacy require the Company and its subsidiaries to maintain minimum
amounts and ratios of total and Tier 1 capital to risk-weighted assets
and of Tier 1 capital to average assets as set forth on the following
page. Each of these components is defined in the regulations.
Management believes that the Company and its subsidiaries meet all
their capital adequacy requirements as of December 31, 2000 and 1999.

of credit in the amount of $200,000 and $300,000 with a director during
2000 and 1999, respectively (see Notes 8 and 14).

The Company entered into an agreement with a director to establish an
unsecured revolving line of credit in the amount of $500,000 during
2000 (see Note 8).

14. EMPLOYEE BENEFIT PLANS

PROFIT SHARING PLAN

The Western Sierra Bancorp and Subsidiaries 401KSOP is available to
employees meeting certain service requirements. The Company's
contribution to the plan is discretionary and is allocated in the same
ratio as each participant's compensation bears to total compensation
for all participants. Contributions totaled $56,000, $80,000 and
$127,000 for the years ended December 31, 2000, 1999 and 1998,
respectively.

EMPLOYEE STOCK OWNERSHIP PLAN

The Employee Stock Ownership Plan (ESOP) is designed to invest
primarily in securities of the Company purchased on the open market.
The purchase of shares is funded through contributions to the ESOP by
the Company and loans from certain members of the Board of Directors.
Contributions to the plan are at the sole discretion of the Board of
Directors and are limited on a participant-by-participant basis to the
lesser of $30,000 or 25% of the participant's compensation for the plan
year. Compensation is defined as all compensation paid during the plan
year which is considered to be W-2 income, to include amounts deferred
under the Company's 401KSOP. Employer contributions vest at a rate of
20% per year after two years of employment. Employee contributions are
not permitted. Benefits may be distributed in the form of qualifying
Company securities or cash. However, participants have the right to
demand that their benefits be distributed in the form of qualifying
Company securities.

During 1999, the ESOP purchased 19,516 shares of the Company's common
stock with the proceeds of a $300,000 loan to the ESOP by a member of
the Board of Directors. During 2000, the ESOP purchased 16,593 shares
of the Company"s common stock with the proceeds of a $200,000 loan to
the ESOP by a member of the Board of Directors. Interest expense of
$40,000 and $17,000 was incurred during the years ended December 31,
2000 and 1999, respectively.

The debt of the ESOP is recorded as debt of the Company and the shares
purchased with the proceeds are reported as unearned ESOP shares in
shareholders' equity. As the debt is repaid, shares are committed to be
released and the Company reports compensation expense equal to the
current market price of the shares. Committed to be released shares are
subsequently allocated to active employees and are recognized as
outstanding for earnings per share and capital ratio computations. Cash
dividends on allocated ESOP shares are recorded as a reduction of
retained earnings and are allocated to the participants; cash dividends
on unallocated ESOP shares are recorded as a reduction of debt and
accrued interest.

Compensation expense of $152,000, $179,000 and $90,000 was recognized
for the years ended December 31, 2000, 1999 and 1998, respectively.

SALARY CONTINUATION PLAN

Under the salary continuation plan, the Company is obligated to provide
eight key executives, or their designated beneficiaries, with annual
benefits for fifteen years after retirement or death. These benefits
are substantially equivalent to those available under insurance
policies purchased by the Company on the lives of the executives. The
estimated present value of these future benefits are accrued over the
period from the effective date of the plan until the executives'
expected retirement dates. The expense recognized under this plan
totaled $186,000, $206,000 and $257,000 for the years ended December
31, 2000, 1999 and 1998, respectively.

Under this plan, the Company invested in single premium life insurance
policies with cash surrender values totaling $2,839,000 and $2,613,000
at December 31, 2000 and 1999, respectively. On the consolidated
balance sheet, the cash surrender value of life insurance polices is
included in accrued interest receivable and other assets. Income on
these policies, net of expense, totaled $66,000, $193,000 and $208,000
for the years ended December 31, 2000, 1999 and 1998, respectively.

15. COMPREHENSIVE INCOME

Comprehensive income is reported in addition to net income for all
periods presented. Comprehensive income is a more inclusive
financial reporting methodology that includes disclosure of other
comprehensive income (loss) that historically has not been
recognized in the calculation of net income. Unrealized gains and
losses on the Company's available-for-sale investment securities are
included in other comprehensive income (loss). Total comprehensive
income and the components of accumulated other comprehensive income
(loss) are presented in the Statement of Changes in Shareholders'
Equity.

At December 31, 2000, 1999 and 1998, the Company held securities
classified as available-for-sale which had unrealized gains (losses) as
follows (dollars in thousands):

16. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

Estimated fair values are disclosed for financial instruments for which
it is practicable to estimate fair value. These estimates are made at a
specific point in time based on relevant market data and information
about the financial instruments. These estimates do not reflect any
premium or discount that could result from offering the Company's
entire holdings of a particular financial instrument for sale at one
time, nor do they attempt to estimate the value of anticipated future
business related to the instruments. In addition, the tax ramifications
related to the realization of unrealized gains and losses can have a
significant effect on fair value estimates and have not been considered
in any of these estimates.

Because no market exists for a significant portion of the Company's
financial instruments, fair value estimates are based on judgments
regarding current economic conditions, risk characteristics of various
financial instruments and other factors. These estimates are subjective
in nature and involve uncertainties and matters of significant judgment
and therefore cannot be determined with precision. Changes in
assumptions could significantly affect the fair values presented.

The following methods and assumptions were used by the Company to
estimate the fair value of its financial instruments at December 31,
2000 and 1999:

CASH, CASH EQUIVALENTS AND SHORT-TERM BORROWINGS: For cash, cash
equivalents and short-term borrowings, the carrying amount is estimated
to be fair value.

INTEREST-BEARING DEPOSITS IN BANKS: The fair values of interest-bearing
deposits in banks are estimated by discounting their future cash flow
using rates at each reporting date for instruments with similar
remaining maturities offered by comparable financial institutions.

TRADING AND INVESTMENT SECURITIES: For trading and investment
securities, fair values are based on quoted market prices, where
available. If quoted market prices are not available, fair values are
estimated using quoted market prices for similar securities and
indications of value provided by brokers.

LOANS AND LEASES: For variable-rate loans and leases that reprice
frequently with no significant change in credit risk, fair values are
based on carrying values. Fair values of loans held for sale are
estimated using quoted market prices for similar loans. The fair values
for other loans and leases are estimated using discounted cash flow
analyses, using interest rates being offered at each reporting date for
loans and leases with similar terms to borrowers of comparable
creditworthiness. The carrying amount of accrued interest receivable
approximates its fair value.

CASH SURRENDER VALUE OF LIFE INSURANCE POLICIES: The fair value of life
insurance policies are based on cash surrender values at each reporting
date as provided by the insurers.

DEPOSITS: The fair values for demand deposits are, by definition, equal
to the amount payable on demand at the reporting date represented by
their carrying amount. Fair values for fixed-rate certificates of
deposit are estimated using discounted cash flow analysis using
interest rates offered by the Company at each reporting date for
certificates with similar remaining maturities. The carrying amount of
accrued interest payable approximates its fair value.

LONG-TERM DEBT: The fair value of long-term debt is estimated using a
discounted cash flow analysis using interest rates currently available
for similar debt instruments.

COMMITMENTS TO EXTEND CREDIT: Commitments to extend credit are
primarily for variable rate loans and letters of credit. For these
commitments, there is no difference between the commitment amounts and
their fair values. Commitments to fund fixed rate loans are at rates
which approximate fair value at each reporting date.
